       TECHNICAL FIELD 
       [0002]    The present embodiments of the invention relate to a wind-powered generator system, and in particular to a compressed-air wind turbine generator system having a substantially square, movable body. 
       BACKGROUND 
       [0003]    Due to the current explosive growth in the world&#39;s population, household energy consumption is on the rise and resources are dwindling. According to some energy resource data reports, more than 85% of all electrical energy is generated from fire, nuclear, oil and gas energies. The use of these energies causes environment pollution and climate change and may directly threaten the lives of animals and humans. 
         [0004]    The traditional wind-powered generator systems used to generate electricity are often referred to as three-blade, fan-type generator systems. Such generator systems have blades similar to the blades of an electric fan which are mounted on the top of a column. Due to the arc shape of the blades, the blades rotate under the action of wind, causing the generator to convert the rotation of the blades into electricity. Such a system has a relative simple structure, but contains shortcomings. Wind power is underutilized in this system because incoming winds do not contact most of the blade area. Due to this inefficiency, several hundreds of such wind-powered generator systems generally can&#39;t provide enough electricity to satisfy the needed electrical load of even a common factory. Further, a large amount of land must be used to satisfy productive requirements leading to a waste of wind and land recourses. 
       BRIEF SUMMARY 
       [0005]    The object of the present invention is directed to overcome the above shortcomings, and to provide a compressed-air wind turbine generator system having a substantially square, movable body such that the system is low cost, efficient in its use of wind power, safe to operate, and has a large installation capacity and longevity. 
         [0006]    In some embodiments of the present invention, the compressed-air wind turbine generator system having a substantially square, movable body that includes: 
         [0007]    a wind turbine B positioned in a central portion of the system, the wind turbine having a central shaft  27  connected to input shafts of generator sets  7 ,  10  that are configured to drive the input shafts to rotate around a rotational central axis z; 
         [0008]    a plurality of compressors A 1 , A 2 , A 3 , A 4 , A 5  for providing compressed air to the wind turbine (B), the plurality of compressors being aligned and stacked at a front side of the system in the direction of the rotational central axis z, the plurality of compressors having outer ends and inner ends, the plurality of compressors extending from the outer ends to the inner ends towards the central portion of the system and tapering along a curve, the outer ends of the compressors jointly containing an air inlet surface [ 50 ,  48 ] with a first width w 1 , and the inner ends of the compressors jointly containing an air outlet surface [ 61 ] which encloses a cylindrical space for concentrically accommodating the wind turbine B; 
         [0009]    a left sail  8   a  positioned on the left side of the system and a right sail  8   b  positioned on the right side of the system, wherein the left sail and the right sail are symmetrically positioned with respect to the center of the system, the left and right sails being arranged close to a rear side of the system and extending from a front side of the system to the rear side such that the distance between the left sail  8   a  and the right sail  8   b  gradually increases; and 
         [0010]    a rear sail  72  positioned at a rear side of the system, the rear sail being arranged closer to the left sail  8   a  or the right sail  8   b,  depending the back profile of the compressors; 
         [0011]    wherein the plurality of compressors, the left and right sails and the rear sail are assembled into a unit in such a way that they can rotate together in a range of 360 degrees with respect to the wind turbine under the action of the sails to keep the air inlet surface of the compressors facing the largest wind. 
         [0012]    The main body of the present system has a shape of triangle. In order to make the air inlet surface just face the direction of incoming air, vertical sails are arranged at the two side edges of the system, and an additional sail is laterally arranged at the rear side edge of the system, thus forming a square-shaped system by means of the sails and the additional sail together with various transverse beams and straight rods. Such a design makes the incoming air flows into the air channels just in the direction of incoming air so that the wind turbine is efficiently driven to rotate. Specifically, the wind enters the compressors from the air inlet surface of the compressors, and then impacts the wind turbines from the air outlet surface after converged and compressed to drive the wind turbines to rotate to generate electricity. The ability of rotating in the range of 360 degrees under the action of the sails can always ensure the air inlet surface to just face the direction of incoming air, so that the various inlets of the system just align with the direction the incoming air to receive all the incoming air, which can improve the utilization efficiency of wind. Therefore, in the same conditions of wind, the utilization efficiency of wind of the present system is eight times greater than that of the traditional fan-type systems, and the power of one system of the present invention is 300 times greater than that of the traditional fan-type system. Moreover, the system of the present invention has a lower cost and remarkably reduces noise. 
         [0013]    Preferably, the overall height of the compressors is substantially identical to the height of the various sails and the wind turbine B; and the sails and the plurality of compressors are secured on a bottom square frame  11  and beams  14 ,  53  of a circular ring derrick, and the square frame  11  and the beams  14 ,  53  of the circular ring derrick are mounted on a circular ring rail  3  and a smooth inner circular ring ground beam  43  by means of pulleys  2 ,  47 . 
         [0014]    In one embodiment of the compressor according to the present invention, five compressors are provided, and each of the compressors includes seven air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  spaced apart from one another, the seven air channels units taperedly extending towards the central portion of the system from their outer ends to their inner ends, forming a substantially bugle shape, and the air inlet surface containing a convex cylindrical surface  50  located at the middle portion of the air inlet surface and planar surfaces  48  located at the two side portions of the air inlet surface. The across section of each of the air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  is substantially quadrangular, and the height of each of the air channel units along the rotational central axis z smoothly decreases from the outer end of this air channel unit to a position of two thirds of the total depth of the air channel unit and then smoothly increases from said position to the inner end of the air channel unit, so that a narrowing portion  23  is created at said position, whereby a respective compressor spacing  18  is formed interiorly between every two adjacent compressors of the plurality of compressors A 1 , A 2 , A 3 , A 4 , A 5 . 
         [0015]    According to the above solution, the respective compressors taper towards the central portion of the system and accordingly form spacing between them. Therefore curved, continuous air channel units are created in such a manner that the converged wind advances under the continuous squeeze and that the compressor interior spacing increases the pressure for moderately expanding the wind to increase outlet wind speed, whereby the impact speed of wind is greatly improved and facilitates the utilization efficiency of wind power. Moreover, seven air channel units with different curves constitute a bugle-shaped compressor which forms a substantially trigonal body in conjunction with the wind turbine. 
         [0016]    Further, the seven air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  are formed by means of an upper panel  21 , a lower panel D 3 , two side panels  16   a,    16   b  and six vertical partitions  52 , and each of the air channel units includes a shorter inlet section, a shorter outlet section and a longer middle section, the inlet section containing multi-stage compression channels D, E, F, G, and the outlet section containing at least one additional horizontal partition  56  and at least one additional vertical partition ( 55 ) for dividing the outlet, both the vertical partition  52  and the additional vertical partition  55  having an angle in the range from 52° to 62° with respect to the diameter line  85  of the wind turbine across the center of the air inlet surface at the inner end of the compressor. The function of the multi-stage compression channels of the inlet section is to prevent the wind after entering the channels from escaping outwards. 
         [0017]    Preferably, five stage compression channels are provided, and the first stage compression channel C is subdivided into thirty second stage compression channels D. Each of the second stage compression channels D is subdivided into four third stage compression channels E, each of the third stage compression channels E is subdivided into four fourth stage compression channels F, and each of the fourth stage compression channels F is subdivided into four fifth stage compression channels G. The inlet and the inner outlet of any stage compression channel have four edges equipped with compression sills  68 ,  63 ,  65 ,  66 , E 1 , E 2 , F 1 , F 2 , D 1 , D 2 , E 5 , E 6 , F 5 , F 6  connected to one another to form a frame. The compression sills of an inlet  67  and an inner outlet D 5  of the first stage compression channel C extend to connect to the upper panel  21 , the lower panel D 3  and two side panels  16   a,    16   b,  respectively. Each compression sill of the inlet  67  includes a H steel bar D 7  and a rolling curved plate D 6  enclosing the H steel bar D 7 . The compression sills D 8  of the inner outlet D 5  consist of round pipes. 
         [0018]    It can be seen according to a test result, that the compression sills bring at least the following advantages. Firstly, it makes the construction of the system more easily and strengthens the system, by means of the compression sill arrangement. Secondly, the compression sill arrangement with double port limitations has no effect on the wind entering the inlets  67 , and once the wind enters the air channels, it will not escape and expand within the air channels, due to the broad interior of the air channel units, so that the wind power at the outlets will be determined by the wind pressure at all the inlets of the system. 
         [0019]    Moreover, the multi-stage compression channels greatly facilitate the construction of large systems. A most advantageous point is that even very large system can be constructed only by dividing the compression channels into more stages and by continuing shortening the air compressing channels D, which will greatly save cost of the system, improve the efficiency of inspiration, and save the cost of construction more easily. 
         [0020]    Alternatively, the multi-stage compression channels can include compression channels with the stages from 2 to 11. 
         [0021]    Preferably, both of side vertical partitions  52  of the fifth air channel unit C 5  gradually close up to the center of the fifth air channel unit along the direction of the curve from the outer end to the inner end of the fifth air channel unit. The right side panel  16   b  and the vertical partitions of the first, second, third and fourth air channel units C 1 , C 2 , C 3 , C 4  are bent towards the fifth air channel unit C 5  from their respective outer ends to their respective inner ends. The left panel  16   a  and the vertical partitions of the sixth and seventh air channel units C 6 , C 7  are bent towards the fifth air channel unit C 5  from their respective outer ends to their respective positions at their respective depths of three fourths, and are then bent from the positions at their respective depths of three fourths to their respective inner ends and deflected from the fifth air channel unit C 5 . Such a design will help reducing the wind resistance.

     DETAILED DESCRIPTION 
       [0051]    The detailed structure of the present invention is further described in conjunction with the drawings; however, the present invention is not limited to the embodiments described herein. 
         [0052]      FIG. 1  is a perspective view of one embodiment of a compressed-air wind turbine generator system having a substantially square, movable body according to embodiments of present invention. In  FIG. 1 , the reference sign A denotes the after-mentioned compressors, and the reference sign B denotes the after-mentioned cylindrical wind turbines. In  FIGS. 4 ,  7  and  8 , the reference signs C, D, E, F, G denote five-stage compression channels (wherein the fifth compression channels G are not shown) of the after-mentioned compressors, respectively. The reference numeral  15  denotes the after-mentioned derrick posts. The dashed lines represent an interior. In addition, various specifications of the system configuration are determined based on the combined width of air inlet surfaces  48 ,  50  (i.e., the first width W 1 ), and the system diameter line  85  is defined to travel across the central line z and across the center of the air inlet surface. In the following description, “front side”, “left and right sides”, “rear side”, “left and right directions”, “inner and outer edges”, and “up and down direction” are all referred with respect to the compressed-air wind turbine generator system of the present invention in an assembled state. The following “radial width” refers to the width measured along the direction of the diameter of the wind turbine. 
         [0053]    In a preferable embodiment as shown in  FIGS. 1 ,  4  and  5 , the whole system includes compressors A 1 -A 5 , a square frame consisting of transverse and straight derrick beams, circular ring derrick beams, various derrick posts, beams, rod bones, sails and compression lines, sills, and various bases, which are all connected to a bottom frame and then mounted on a circular ring rail and a chassis base by means of pulleys; and a cylindrical wind turbine, wherein the wind turbine includes wind turbine units positioned within the space for moving and assigned to the inner edges of the respective compressors, and wherein the lower end of the central shaft of the wind turbine is connected to the upper end of a connector of a chain wheel and the lower end of the connector is engaged with an inner gear. The inner gear also engages with a column gear and an input shaft of the generator sets. Wind enters the inlet through the air inlet surface of the compressors, and is converged and compressed through the compression lines and the air channel units, and then impacts the space for moving outside of the outlets, and in turn drives the wind turbine to rotate to generate electricity. 
         [0054]    Specifically, five compressors A 1 , A 2 , A 3 , A 4 , A 5  are stacked at the front side of the system and are aligned with one another along the rotational central axis z. The five compressors taper as they extend along a curve towards the central portion of the system from their outer ends to their inner ends, respectively, jointly forming an air inlet surface with a first width W 1  at the outer ends of the compressors. An air outlet surface  61  is jointly formed at the inner ends of the compressors, and encloses a concentrically cylindrical space for accommodating the wind turbine B. The air outlet surface  61  has an area being 48%-58% of the area of the periphery surface of the wind turbine. A radial air exhausting spacing  18  is formed interiorly between two adjacent compressors of the five compressors. The cylindrical wind turbine B is positioned within the concentrically cylindrical space. The left and right sails  8   a,    8   b  are arranged at both left and right side edges of the system, and the rear sail  72  is arranged behind the central portion of the system. The compressors and the sails constitute an integral device. Under the action of the left and right sails  8   a,    8   b  and rear sail  72 , the integral device can rotate at an angle in the range of 360° so that the air inlet surface  48 ,  50  naturally rotates in the range of 360° to face the incoming air to receive wind power from various directions. 
         [0055]    The compressed-air wind turbine generator system according to the present invention firstly has a chassis base containing outer and inner circular ring ground beams  1 ,  43 . The chassis base includes various straight ground beams  45 ,  46  extending inwards from a peripheral guardrail web  35  and mounting bases of generator sets  7 ,  10 . A circular ring rail  3  is positioned in the plane of the outer circular ring ground beam  1  and engages bottom pulleys  2  to perform a relative movement. Each of pulleys  2 ,  47  are mounted at the bottom of the outer and inner circular ring derrick beams  53 ,  14 . The outer and inner circular ring derrick beams  53 ,  14  are integral with a bottom square frame  11  combined of transverse and straight derrick beams  4 ,  17 .

The vertical sails  8   a,    8   b  and rear sail  72  are connected to the upper straight and transverse beams  32 ,  70  and support rod bones  31 . The compression lines (dashed line  22 ) within the body of the compressors A and round tube posts  49 ,  75 ,  76  are welded into a unitary body. 
         [0056]    There are several derrick beams  59  provided at the bottom of the cylindrical wind turbine B. The derrick beams  59  are combined with the inner circular ring derrick beam  14  and pulleys  47 , and aligned within the inner circular ring ground beam  43 . The derrick beams  59  extend inward to a planar bearing  58  positioned in the central mounting plane, and are fixed with the central shaft  27  of the wind turbine B. The central shaft  27  is connected to a coupler  12  of the chain wheel.

The top mounting frame  30  of the wind turbine B is connected to the circular ring frame  26  for securing a top bearing  28  of the wind turbine B and for supporting connect beams  29  and the central shaft  27  of the wind turbine B. The top mounting frame  30  is aligned with a top circular plate  25  of the wind turbine B and the whole wind turbine B. An up-and-down radial air exhaust space  24  is provided within the top mounting frame  30  for axial air exhaust. 
         [0057]    In the following, the chassis base and the bottom frame of the system are described in detail with reference to  FIG. 2  and  FIG. 3 . 
         [0058]    The system chassis base is provided with the inner and outer circular ring ground beams  43 ,  1 . There are a working chamber  44  of the central generator sets, an annular wall  34  and square posts  33 , wherein the posts  33  are coupled with various straight beams  45  extending outwards. The smooth inner circular ring ground beam  43  and the outer circular ring ground beam  1  are coupled with each of the straight beams  45  and additional straight ground beams  46 . Four tunnels are also provided under the ground beams of the system chassis, and are communicated with the working chamber  44  through an outer doorway  40  and an inner doorway  42 , and communicated with a circular ring working passage  39  through an intermediate doorway  41 , and in turn communicated with each of gates  51  of electrical lifts within the system through the circular ring working passage  39 . As shown in  FIG. 2 , the guardrail web  35 , viewing channels  37 , inner handrails  36 , an isolated space  38  and an engagement device for the sliding circular ring rail  3  and the bottom pulleys  2  are arranged in a plane around the outer edge of the chassis. As shown in  FIG. 3 , the square frame  11  is provided with various transverse and straight derrick beams  4 ,  17  which are connected to the inner and outer circular ring derrick beams  14 ,  53 . The square frame  11  includes foundations for the derrick posts  15 ,  13 ,  5 , foundations for the vertical sails  8   a,    8   b  and additional sail  72 , foundations for the round tube posts  49 , foundations for the partitions  52  of each unit C 1 ˜C 7  of the compressor A, foundations for various straight sills  65 ,  64 , D 1 , E 2 , E 5 , F 2 , F 5  in the vertical air inlet surface  50 ,  48  for receiving wind, and foundations for the pulleys  2  with a groove and the smooth pulley  47 , and so on. All the foundations are welded into a unitary body. The transverse and straight derrick beams  4 ,  17  can be added within the position of the compressor A, and have the specifications depending on the system volume. The planes of the inner and outer circular ring ground beams  1 ,  43  keep precise balance. The number of the pulleys  2 ,  47  arranged at the position of the compressor A is at least three times greater than those arranged at the outside. The inner and outer derrick posts  13 ,  15 , the circular ring derrick beams  14 ,  53 , oblique support derrick posts  5 , and the transverse and straight derrick beams  4 ,  17 , and so on, are all made from round tubes and welded. 
         [0059]    The structure of the compressor A will be described below in detail with reference to  FIG. 4  and  FIGS. 5 to 9 . 
         [0060]    The compressor A is formed as a bugle-shaped compressor A body assembled by ten plates, and the ten plates of the compressor A are respectively one lower panel D 3  and one upper panel  21 , two side panels  16   a,    16   b  and six vertical partitions  52  that separate the air channel into the air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7 . The vertical partitions  52  taper inwardly and continuously (the upper and lower edges of the vertical partitions  52  taper inwardly and continuously) from the widest point of the outer edge (inlet  67 ) to a narrowest point (namely, a narrowing portion  23 ). The narrowest point is located at a position in any of the air channel units C 1 -C 7  that is a distance of two thirds of the total length of the partitions  52  as measured from the outer edge of any of the air channel units C 1 -C 7 . Then, the vertical partitions  52  enlarge continuously from the narrowing portion  23  to an air outlet  57 , wherein the height of the narrowest portion of any of the air channel units C 1 -C 7  is about 67% of the maximum width of the vertical partitions  52 , and the width at the air outlet  57  is about 93% of the maximum width of the vertical partitions  52 . The width of the vertical partitions  52  corresponds to the height of each of the air channel units C 1 -C 7 . 
         [0061]    As shown in  FIGS. 4 ,  5 ,  6  and  9 , the compressor A is formed of seven air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  tapered along different curves of the respective compressors A 1 , A 2 , A 3 , A 4 , A 5 , and the compressors A 1 , A 2 , A 3 , A 4  and A 5  are stacked to form a compressor assembly. As shown in  FIG. 9 , the air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  vary in curve and depth, the inlets  67  of the air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  are the same in height, the height of the outlet  57  is 93% of the height of the inlet  67 , and the height of the radial air exhausting spacing  18  is 7% of the height of the inlet  67 . 
         [0062]    The respective air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  are each a hollow quadrangular structure, each unit tapers inwardly from the inlet  67  of the vertical air inlet surfaces  48 ,  50  at the outer edge to the outlet  57 . Compared with the area of the inlet  67 , the area of the outlet  57  is reduced by 61%. Secondly, as shown in  FIG. 9 , the partitions  52  at both sides of the air channel unit C 5  substantially and symmetrically narrow at the center of the air channel unit from the inlet  67  to the outlet  57 , and the other air channel units C, such as C 6  and C 4 , as well as C 7  and C 3 , C 2 , C 1 , are all curved towards the air channel unit C 5 , for instance, the partitions  52  of the units C 6 , C 7  and the external side panel  16   a  are curved from the narrowing portion  23  inwardly and then outwardly to an inner edge of the air outlet surface  61  of the system. As shown in  FIG. 4 , the outlet  57  of the respective air channel unit C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  is provided with an additional vertical partition  55  and an additional horizontal partition  56  The additional vertical partition  55  and the additional horizontal partition  56  extends from the outlet  57  into the air channel. The width of the additional vertical partition  55  and additional horizontal partition  56  is about 5% of the total combined width of the air inlet surfaces  48 ,  50 , and the height of the additional vertical partition  55  is the same as that of the outlet  57 . Each additional vertical partition  55  forms an eccentric angle of 56° with respect to the diameter line  85  adjacent to the outlet  57 , and the side panels  16   a,    16   b  form an eccentric angle identical with that of the vertical partitions  52  with respect to the diameter line  85  adjacent to the outlet  57 . 
         [0063]    As shown in  FIGS. 5 ,  6 ,  7  and  9 , the air inlet surfaces  48 ,  50  constitute a wind source receiving inlet  67 . The inner edge of the air outlet surface  61  encloses a substantially semi-circle moving space for mounting the cylindrical wind turbine B. It can be seen from the vertical partitions  54  and the main horizontal partitions  60  as indicated by dashed lines in  FIG. 5  that the wind source receiving inlet  67  is provided with a wind source compression channel D facing inwardly, the inner width of which is about 5% to 7% of the total combined width of the air inlet surfaces  48 ,  50  of the compressor A. Each compression channel D tapers inwardly from the inlet  67  to the inner outlet D 5  such that total volume of the channel D is reduced by 7%. The inlet  67  section of the respective air channel unit C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  is provided with the wind source compression channel D, while the outlets  57  are each provided with the additional vertical partitions  55  and the additional horizontal partitions  56 . Except for the round tube posts  49 ,  75 ,  76  and the gates  51  of electrical lifts inside the air channel unit C, the other inner sections are all hollow quadrangular prisms. 
         [0064]    As shown in  FIGS. 3 ,  6  and  9 , five external edges of the air channel unit C 2 , C 3 , C 4 , C 5 , C 6  forming the air inlet surface  50  are arranged in the range of 0.9/4 of the perimeter of the external circular ring ground beam as shown in  FIG. 3 , and the external edges of the air channel units C 2  to C 6  extend beyond the circular ring ground beam  1 , the length beyond the circular ring ground beam  1  is about 0.1% to 0.5% of the perimeter of the circular ring ground beam  1 . The external edges of the air channel units C 1  and C 7  are parallel to the beam  4 . Similarly, the length of the air channel units C 1  and C 7  beyond the beam  4  is about 0.1% to 0.5% of the length of the beam  4 . As shown in  FIG. 6 , the respective compressors A 1 , A 2 , A 3 , A 4 , A 5  are closely stacked along sills  68  to form a huge grille for receiving the wind source at the air inlet surfaces  48 ,  50 , and then under the effect of the vertical sails  8  and rear sail  72 , the air inlet surfaces  48 ,  50  of the system receive wind from all around. 
         [0065]    As shown in  FIGS. 7 and 8 , the wind source compression channel D is divided by the inlet  67  section of the air channel unit of the compressor A, and each unit divides the first stage compression channel C into  30  compression channels D by five vertical partitions  54 , four horizontal partitions  60 , and horizontal partition D 9 . As shown in  FIG. 7 , the compression channel D from the inlet  67  to the inner outlet D 5  is an air channel having a shape of a hollow quadrangular prism, and the inlet  67  and the inner outlet D 5  are each provided with wind source compression sills  66 ,  65 , D 8 . The compression sill D 8  of the inner outlet D 5  uses a round tube as a horizontal sill D 2  which intersects with a vertical sill Dl to connect the side panels  16   a,    16   b , the vertical partitions  52 , the upper panel  21  and the lower panel D 3  and so on of the compressor A. In  FIG. 7 , the side panels  16   a,    16   b  and the vertical partitions  52  are delimited by a dissecting line D 4 , which interior will not be discussed herein. The H steel bar D 7  is used to connect the overlapped vertical sills  63 ,  64  and the horizontal sills of each unit inside the compression sills  66 ,  65  of the inlet  67 , wherein the vertical sills  63 ,  64  and  65  are connected to the frame  11  at the bottom of the system, and the vertical sills include the compression sill Dl of the inner outlet D 5 , the vertical sills E 2 , F 2  of the compression channels E, F subdivided in  FIG. 8 , and the vertical sills E 5 , F 5  of the inner outlet D 5 , which are connected to the frame  11  at the bottom of the system. Various compression sills of the inlet  67  are connected to the external edges with the H steel bar D 7  inside which is enclosed by a curved roll formed of the plate D 6 , in such a way that various stages of the compression sills are formed into an oval shape with two external pointed edges. As shown in  FIG. 8 , an extra large-sized system has compression channels continuously divided into at least 5 stages. The first stage compression channel C is divided into 30 second-stage compression channels D, each compression channel D is divided into 4 third-stage compression channels E, each compression channel E is divided into 4 fourth-stage compression channels F, each compression channel F is divided into 4 fifth-stage compression channels G, which can be further divided by analogy. The compression channel tapers from the inlet  67  to the inner outlet D 5 , with a tapered degree of 0.2° to 0.3° . As can be seen in  FIG. 8 , the vertical compression sill E 2  and the horizontal compression sill E 1  inside the inlet  67  of the compression channel D withdraw towards the interior of the compression channel and are then mounted in the vertical partitions  54  and the horizontal partitions  60 , and the vertical and horizontal sills E 5 , E 6  at the inner outlet D 5  are also mounted in the vertical partitions  54  and the horizontal partitions  60 . The compression channel E is about 5% shorter than the compression channel D. Similarly, the compression channel F is about 5% shorter than the compression channel E. The vertical partitions E 4 , F 3  of the compression channels E and F are also correspondingly shortened so as to be mounted in the pointed parts of the sills E 1 , E 2 , F 1 , F 2 , and the pointed parts include the vertical partitions  54 , the horizontal partitions  60  and sills  65 ,  66  of the compression channel D as well as the horizontal and vertical sills D 2 , D 1 , E 6 , E 5 , F 6 , F 5  of round tube. As shown in  FIG. 8 , the compression sills E 1 , E 2  of the compression channel E of the inlet  67  are reduced by 10% in length in comparison with the sills  65 ,  66  of the compression channel D, and the sills F 1 , F 2  of the compression channel F are reduced by 10% in length in comparison with the sills E 1 , E 2  of the compression channel E, and the sills D 1 , D 2 , E 5 , E 6 , F 5 , F 6  of the round tube of the inner outlet D 5  are reduced by 3% in length in comparison with the compression sills of the compression channel at the same stage of the inlet  67 . All the horizontal compression sills, such as the air inlet surfaces  48 ,  50  and the inner outlet D 5 , extend thoroughly through the compression channels to connect the left and right side panels  16   a,    16   b,  the upper panel  21  of the connecting device of all the vertical compression sills, the compression channels of the compressors A 5  to A 1 , and the frame  11  at the bottom of the connecting device, thereby forming a connected body. Due to the effect of the dual compression sills in conjunction with the tapered compression channels, no wind source can escape from the compression channels no matter it is big or small. A self-compressed wind turbine B is formed, wherein the rotational force of the wind turbine B is equal to the wind collecting pressure on large areas of the air inlet surfaces  48 ,  50 , thereby driving the wind turbine B in high-speed rotation. 
         [0066]    As shown in  FIG. 9 , the compressed-air wind turbine generator system is centered about the wind turbine B, in combination with the compressor A and the vertical sails  8   a,    8   b  and rear sail  72 , thus forming a square-shaped system which has a transverse width that is 8% greater than the longitudinal length thereof, the greatest distance  1  between the sails  8   a,    8   b  placed opposite to each other at two sides of the system is about 5% more than the overall width W 1  of the air inlet surface  48 ,  50  of the compressor A, and the length of the outer diameter line  85  of the wind turbine B is 32% of the overall width W i  of the air inlet surfaces  48 ,  50 . The vertical partition  52  (including the side panels  16   a,    16   b ) of each of the air channel units C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7  of the compressor A is arcuately curved toward the unit C 5 , and tapers the air channels toward a gap  73  between the compressor and the wind turbine B. the vertical partitions  52  (including the side panels  16   a,    16   b ) are gradually widened outward to the vertical air inlet surfaces  48 ,  50 , the air channel units C 1 , C 7  are placed along the derrick crossbeam  4 , forming the vertical air inlet surface  48  parallel to the derrick crossbeam  4 , the intermediate five air channel units C 2 , C 3 , C 4 , C 5 , C 6  are disposed within the range of 0.9/4 of the perimeter of the externally tubular ground beam  1 , forming a projecting cylindrical vertical surface  50 . The tube posts  49 ,  75 ,  76  are disposed with limitations, wherein the tube post  49  is located adjacent the vertical partition  54 , the tube post  75  is disposed within the narrowing portion  23 , and whether to increase the number of other tube posts  76  is dependent on the practical demand. The vertical sails  8   a,    8   b  are symmetrically disposed at two side edges behind the compressor A, an additional sail  72  is disposed at a location deviation to right at the rear side edge, each of the sails  8   a,    8   b,    72  generally has five to six curved and rolled blades  9  which are vertically arranged in a line and are the same height as the system, wherein the curved and rolled blades  9  of the opposite sails  8   a,    8   b  have different specifications. An adjacent blade, as compared with a blade closest to the compressor A, is widened 7%, and it follows that the rest blades are in turn widened 7%. The blades of the rear sails  72  are transversely arranged along the rear side edge of the system, without being widened. Transverse derrick beams  69 ,  70  and vertical derrick beam  71  and the derrick posts  15 ,  13  all can be designed based on the specification of the system, wherein the amounts, volumes and positions thereof are calculatingly determined by the specification of the system. 
         [0067]    It is necessary to indicate that as the plurality of compressors are spaced apart from each other in an up-and-down direction and are overlapped with each other with intervals, it is practical to dispose a plurality of tubular posts at the intermediate vertical partition in each air channel and elevator passageways which are disposed through each compressor, and are connected to the bottom frame, including an external derrick post, such an arrangement is used for securing and maintaining the large-scaled systems of more than 10 MW. 
         [0068]    Detailed illustrations are provided as follows for the wind turbine of the present invention with reference to  FIGS. 10-12 . 
         [0069]    The reference sign B, shown as follows, indicates a wind turbine unit, and reference signs  20 ,  82  are used to indicate the same space. 
         [0070]    The wind turbine B, has a cylindrical shape having an outer cylindrical surface  87  and an inner cylindrical surface  89 , comprises a top circular plate  25 , a bottom circular plate  77 , as well as five wind turbine units B 1 , B 2 , B 3 , B 4 , B 5  and four radial air exhaust spaces  82  located between the top circular plate  25  and the bottom circular plate  77 . The middle of the wind turbine B is a hollow cylindrical space. The central shaft  27  is connected to the circular plates of each unit B, respectively, by a radially outwardly extending connecting beams  29 , said circular plates including the top circular plate  25  and the bottom circular plate  77 . The overall height of the cylindrical wind turbine B depends on the number of overlapped compressors A of the system. 
         [0071]    Each of the units B 1 , B 2 , B 3 , B 4 , B 4  of the wind turbine B respectively includes two circular panels  98 ,  99  (i.e. a top one and a bottom one) and blade sets  80 ,  92 ,  93 , as shown in  FIG. 11 , in a body plane B 8  of the circular plate B 7 , are disposed the outer blades  80 , the intermediate blades  93 , the inner blades  92  as well as the internally tubular posts  90  and the externally tubular posts  91 , respectively. The outer blades  80 , the intermediate blades  93  and the inner blades  92  are connected to each other, forming two folds and three bends. Said outer blades  80  are connected inward from the outer cylindrical surface  87  of the circular plate B 7  to a location of the externally tubular post  91 , with a radial width of the external blades from the outer cylindrical surface  87  to said location being 37% of a unilateral radial width W 2  of the body plane B 8  of each circular plate B 7 . The intermediate blades  93  are connected to the externally tubular post  91  and the internally tubular post  90 , respectively, with a radial width of the intermediate blades  93  from the externally tubular post  91  to the internally tubular post  90  being 38% of the width W 2 . The inner blades  92  are connected to the internally tubular post  90 , and a radial width of the internal blades from the internally tubular post  90  to the inner cylindrical surface  89  of the circular plate B 7  being 25% of the width W 2 , the internally tubular posts  90 , in a total number of  32 , are uniformly distributed along the entire body plane B 8  of the circular plate B 7 , and the number of externally tubular posts  91  is  64 , said two kinds of tubular posts  90 ,  91 , which respectively extend from the double-joined bottom circular plate  77  at the bottom plane of the wind turbine B through each unit B 1 , B 2 , B 3 , B 4 , B 5 , include circular plates B 7  on each layer, additional circular plates  78  and interlayered air exhaust spaces  82 , and a top circular plate  25  connected to the wind turbine B. 
         [0072]    As shown in  FIG. 11 , the plane B 8  of the interlayered circular panels  98 ,  99  of the wind turbine B is divided into three portions, i.e. the inner portion, the intermediate portion, and the outer portion, which three portions exactly are mounting positions of the outer blades  80 , the intermediate blades  93  and the inner blades  92  of each of the units B 1 , B 2 , B 3 , B 4 , B 5 , e.g. the external blades extend from the outer cylindrical surface  87  of the circular plate B 7  to the externally tubular post  91 , with the body line thereof extend inwardly to form an angle of  35  degree with respect to the diameter line  85 , on the contrary, the intermediate blades  93  and the inner blades  92  extend outwardly to form an angle with respect to the diameter line  85 , respectively, with the angle between the inner blades  92  and the diameter line being 70 degrees and the angle between the intermediate blades  93  and the diameter line being 50 degrees, the outer blades  80  are in the form of a elliptical semi-body, with the depth of the curves thereof being 25% of the width thereof, the intermediate blades  93  are semi-arcuate, with the depth of the curves thereof being 43% of the width thereof, and the inner blades  92  are arcuate, with the depth of the curves thereof being 13% of the width thereof. The number of said inner blades  92 , intermediate blades  93 , and outer blades  80 , which are connected to form two folds and three bends are divided into three portions each of which includes  32  blades based on  64  internally tubular post  90  and externally tubular post  91 . In addition, the additional outer blades  95  include  32  tubular posts  91 . in the air inlet port  79  between the outer blades  80  and the additional outer blades  95 , are further provided with a plurality layers of curved wedge plates B 6  for enhanced connection of the surrounding of the wind turbine B, and in the plane B 8  of the interlayered circular panels  98 ,  99 , each blade  92 ,  93 ,  80  forms a torch-shaped pattern of two folds and three bends. But in the interlayered air exhaust space  82  are disposed only  64  external wind exhaust blades  81  equal to the total number of the outer blades  80  and the additional outer blades  95 . Inside, there are disposed only circular tubes  96 , instead of blades, for connecting angle iron posts  94  in the unit B, all the ends of the circular tubes  96  are connected to each other through each unit B and the radial exhaust space  20  is connected to the bottom and top circular plates  77 ,  25 , the respective number of said circular tubes  96  and the angle iron posts  94  is  32  equal to that of the inner blades  92 . As shown in  FIG. 12 , two side edges of the angle iron posts  94  are mounted on the front side of the inner blades  92 , but the angle iron posts  94  have a square angle of 90 degrees which cannot extend beyond the inner edge of the inner cylindrical surface  89  of the circular plate B 7 , and the angle iron posts  94  have a dimension which occupies 50%-90% of the width of the air exhaust port  88  of the inner edge of the inner cylindrical surface  89 . from the layout of the inner, intermediate and outer blades  92 ,  93 ,  80  in the plane B 8  of the circular plate B 7 . As shown in  FIG. 11 , it can be seen that each of the units B 1 , B 2 , B 3 , B 4 , B 5  has a narrow air inlet port  79  and an internally wide air inlet space, which arrangement enables easy wind entry and expansion occurred in the interior wind sources, forming a wind force that can balance the overall suction force. As shown in  FIGS. 5 and 6 , with respect to the inner edge of the air outlet surface  61  of the compressor A, half of the periphery plane of the outer cylindrical surface  87  of the wind turbine B belongs to the space of the air inlet port  79  while the rest belongs to the air exhaust space, in addition to the interlayered radial air exhaust space  82  and the up-and-down radial air exhaust space  24 , and 47% of the area of the outer cylindrical surface  87  of the wind turbine B is the air inlet port  79  while 53% thereof is the combined air exhaust space. 
         [0073]    The diameter of the units B 1 , B 2 , B 3 , B 4  and B 5  will now be explained. The diameter herein refers to the diameter of the outer cylindrical surface  87 , and is sized to be 32% of the combined width of the air inlet surfaces  48 ,  50  of the compressor A. The circular plate B 7  occupies 29.5% of the diameter, and the portion  86  of the inner blades  92  extending beyond the exhaust port  88  of the inner edge of the inner cylindrical surface  89  of the circular plate B 7  occupies 1% of the diameter, the cylindrical body of the space  24  occupies 69.5% of the diameter. The height of the unit B is 0.3% to 1% more than the total height of the outlet  57  of the compressor A, and the height of the exhaust space  20  is 0.3% to 1% less than the height of the spacing  18  of one upper compressor A and one lower compressor A. These sizes are of the inlet port  79  of the units B 1 , B 2 , B 3 , B 4 , B 5  of the wind turbine B with respect to the outlet  57  of the inner edge of the air outlet surface  61 . As shown in  FIG. 12  taken along the line  97 , the exhaust space  20  has an upper circular panel  98  and a lower circular panel  99 , and is inclined at an angle of 5° to 10° from inside to outside, and the unit B is inclined at an angle of 5° to 10° from outside to inside. 
         [0074]    When used in a typical large-sized device, the units B 1 , B 2 , B 3 , B 4  and B 5  of the cylindrical wind turbine B must be provided with multiple layers of additional circular ring panel  78  because the spaced unit of each spaced inlet port  79  has a height not more than two meters, and a width not more than 1.8 meter. The additional circular ring panel  78  is used to reinforce the wind turbine B, while the unit B of the wind turbine B and the spaced exhaust space  82  are dependent on the number of the layers of the compressor A required according to the size of the device, and may be additionally increased. The connecting ends of the beams  29  welded to the inner cylindrical surface  89  of the circular panels  25 ,  77 ,  98 ,  99  and circular plate B 7  are gradually widened towards to the inner cylindrical surface  89 , while the other ends thereof are fixed with the central shaft  27  via a flange  83 . The lower end of the shaft  27  is connected with the planar bearing  58 , and the upper end thereof is narrowed to be neck for mounting a bearing  28  in engagement with the flange  83  of a bearing housing  74 , so as to connect the mounting frame  30  and the circular ring frame  26 . However, the number of the beams can be determined as actually required. 
         [0075]    The units of the wind turbine are all coupled to the central shaft by means of the beam bone. The upper end of the central shaft is fixed by the bearing, and the lower end thereof is connected with the sprocket connector by the planar bearing and then inputs the kinetic energy into the generator assembly by a push bearing. This is a rough process and can be easily constructed no matter how large the system is, which can simplify the construction and further save the cost. 
         [0076]    Furthermore, the specifications and sizes of the device are calculated based on the width of the air surfaces of the compressor. However, the eccentric degree of the curves of the compressor are all calculated based on the center of the wind turbine with respect to the air surface of the compressor, and the air supply area of the movable space only occupies about 47% of the actual area of the external edge of the wind turbine, and the rest 53% thereof is the air exhaust area of the wind turbine. 
         [0077]    The present device varies greatly in size, for instance, a small-sized device can generate 100W for streetlight illumination, and a large-sized device can generate 1 million KW, such that the large-sized device generates a power which is about thousands of times of the small-sized device. The increase of the capacity of the device can be achieved by division of the compression channel at more levels and addition of blades, curved wedge plates, external cylindrical posts and outer blades. Such a design makes the device more compact and cost-effective.
