Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a natural power about wind energy, sea wave energy, and solar energy. These energies are used in large energies. For example, wind power is generated by wind force to drive a generator, it is effective as the wind is strong. Thus, it is confined by geography and thus cannot be used widely. For example, sea wave energy cannot be performed effectively. Since the sea level is not fixed, which changes with time, hour, day and month. Moreover, the size of the sea wave is irregular. For example, in solar energy generation, the output is viewed as a load. In application, according to the requirement of load, a large amount of solar batteries are necessary. Thus, the cost is high and does not conform to the requirement of economics. 
     SUMMARY OF THE INVENTION 
     Therefore, the present invention severs to use low power energy from natural power. In the present invention, power is accumulated and stored to become high power energy and then is used effectively. Currently, most areas have low or middle powers, thus, by the present invention, these low power energy can be used widely without any pollution and thus conforms the requirement of economics. The area arranged according to the feature of the present invention can be programmed as an appreciating area. 
     The primary structure of the present invention is formed by energy conversion devices, air storing tanks, energy accumulating devices and a reservoir. By the power of natural power, and energy conversion devices, the power can be converted as dynamic energy of air for being stored in an air storing tank. Then the energy in the air storing tank serves as power for rising water in a low level to a high level. Finally, this high level water flows into a reservoir to accumulate to a predetermined amount for further being used. The energy conversion devices of the present invention can be classified into three classes. 
     In the present invention, according to the features of geography, one or more energy conversion devices can be used. For example, in seashore, wind energy conversion devices, sea wave energy conversion devices and solar energy conversion devices can be used. In the land, wind energy conversion devices and solar energy conversion devices can be used. 
     The solar energy conversion device is currently used, and thus, it is not the primary concern of the present invention. The wind energy conversion device uses directional wind blades which swing with the wind direction. The directional power serves to control the wind blades. As the wind blade moves along the wind direction, then it is vertical. Inversely, it is horizontal to accept a minimum wind resistance. Therefore, the wind energy can be converted into rotary power to drive air pumps so as to become air dynamics. The power of air is further stored in an air storing tank. The air power from the air pumps can be classified into two classes: one is high pressure air with a pressure larger than atmosphere pressure, and one is low pressure air with a pressure smaller then atmosphere pressure. 
     In the sea wave energy conversion device, a movable pontoon moving with the level of sea wave stops on the sea level. When sea wave is high (higher than sea level), the pontoon will rise by buoyancy. When sea wave descends, the pontoon will descend due to weight itself. Therefore, whenever the pontoon rises or descends, by a set of linkage and ratchet, the pontoon can generate a rotary power. Then, by the transmission assembly, a continuous rotary power is generated. This power will output with the displacement of pontoon and numbers of displacement. Thus rotary force may directly drive air pumps to generate dynamic power of air. This air power is stored in an air storing tank. 
     In the present invention, the energy accumulating device uses the air power of air storing tank (high pressure or low pressure). The object thereof is to rise water of low level to high level. In this system, according to the pressure of the air storing tank it can be classified as high pressure air and low pressure air. In the system for using a high pressure air, a container with a fixed volume is used. As the water of low level is full, a high pressure air is input to push water to a level of high pressure (atmosphere pressure). The potential energy from level difference of water is equal to the difference of air pressure. In the height, an identical container is located and is sustained in an atmosphere pressure for receiving this water of low level. When the water in the container is completely drained out gradually, the high pressure air is closed and atmosphere is communicated. Then, the container is restored to the original state for storing water. Thus, the water in one container can be driven by air energy to be risen to a container with a fixed height. Similarly, in the container of fixing height, the water therewithin can be drive by the same high pressure air to be further risen to another container of fixed height. The process can be repeated. Such driving force of high pressure air can be transferred to different containers of different levels. Namely, the water level can be risen stage by stage. 
     In the energy accumulating device of the present invention, a container of fixed volume is communicated with a low pressure air to be at a lower pressure. Thus, for water of low level, in atmosphere pressure, it can be risen to a container (the potential for rising water is equal to the energy of difference of air pressure. As water is full. The low pressure air source is closed and is communicated with atmosphere. Therefore, for the water in low level and in atmosphere pressure, if it is absorbed by a low pressure air, the water will rise to a container of fixing height. Similarly, the water in the container of fixing height can be absorbed by the same low pressure air so as to be risen to another container of another fixing height. Therefore, by this absorbing force of low pressure air, the water in lower level can be transferred to different layers. 
     In the present invention, a natural power of low or middle power can be converted to rise the level of water so that the energy is stored in a water. Therefore, the cost is low. Moreover, the present invention conforms to the requirement of environmental protection. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 is a schematic view about energy conversion of a natural power. The energy of natural energy source is converted to be stored in air, then the energy is further stored in an energy accumulating device for converting the water level from a lower level to a high level. 
     Water  1  in FIG. 1 is in high level, The water  1  is firstly stored in a reservoir  2 . A water tube  3  serves to output water from an energy accumulating device  4 . Sea water  6  is in lower level, which is input to the energy accumulating device  4  through a check valve  5 . One end of the air storing tank  7  is connected to the energy accumulating device  4 , while another end is connected to an air transmission tube  8 . A plurality of energy conversion devices  12  are installed at the seashore  10 . Each four energy conversion devices  12  are fixed by a connecting body  13  so as to form an energy conversion region  14 . The extension region  15  represents the expansion of the energy conversion region  14 . The energy converted by the energy conversion region  14  is concentrated in the air transmission tube  8  through an air valve  9  by an air transmission tube  11 , and then enters into the air storing tank  7 . 
     The energy of natural power is converted by the energy conversion device  12  to be stored in air, then the air enters into an air storing tank  7 . The energy accumulating device  4  uses the dynamic energy of air in the air storing tank  7  to convert the sea water  6  of lower level to the sea water  1  of high level. 
     Please refers to FIGS. 2,  2 A and  2 B. There are four supporters  21  which are fixed by connecting bodies  13 . A pontoon  23  and a pontoon  25  are connected to the supporters  21  by linkages  83  and  93 . The air transmission tube  26  is connected to the air transmission tube  28 , air valve  9  and wind energy conversion device  100  through the air valve  27 . 
     There are two energy conversion devices, as shown in FIG. 2B, wherein the upper layer is the wind energy conversion device  100 , and the lower layer is the sea wave energy conversion device  200 , with the supporter  21 , fixed on the floor  24  of the sea near the seashore, supporting both devices. 
     At the upper layer of the supporter  21 , there are three wind energy conversion devices  100  installed with an equal angle, and the wind blades within each device, when driven by wind, are independently capable of rotating and outputting power. 
     The sea wave energy conversion device  200 , at the lower layer of the supporter  21 , contains two pontoons  23  and  25  which, by moving up and down following the sea wave, can provide kinetic energy through connecting apparatus. 
     In the energy conversion region  14 , each supporter  21  has two kind of energy conversion devices, one is wind energy conversion devices  100 , which including three devices that are installed with an equal angle. Another is sea wave energy conversion device  200 , wherein the pontoon  23  and pontoon  25  are serves to convert the energy of sea wave. The air dynamic energies from these two energy conversion devices are output through an air transmission tube  26 . Through the air valve  27 , it is connected to the air transmission tube  28 . Finally, the air dynamic energy is output from the air valve  9 . 
     In FIG. 3, the supporter  21  and the supporting rod  33  are connected as a rigid body. The transmission shaft  35  is supported on the supporting rod  33  by a bearing  34 . A direction blade  37  is connected with a cam  38 , and is connected to a transmission shaft  35  by a bearing  36 . A linkage  39  is supported by a supporting shaft  40  which is fixed to the transmission shaft  35 . One end of the supporting rod  41  is fixed to the transmission shaft  35  so as to rotate synchronously with the transmission shaft  35 . Another end thereof is combined with a wind blade  43  by a bearing  42 , and thus, the wind blade  43  also rotates synchronously with the transmission shaft  35 . The sleeve  44  on the wind blade  43  is driven by the linkage  39  so that the wind blade  43  swings with a supporting rod  41 . A curved wheel  45  is fixed to the transmission shaft  35 . A curved shaft  46  is connected to the curved wheel  45  and linkage  47 . Another end of the linkage  47  is connected to the supporting shaft  48 . The supporting shaft  48  pushes the air pump  49 . The supporting rod  50  supports the air pump  49  to be fixed to the supporting rod  33 . The extension regions  78  represent the expansion of the wind blade  43 . 
     The direction blade  37  and the wind blade  43  in FIG. 3 are driven by wind. The direction blade  37  rotates along the wind direction so as to stop in certain orientation, and therefore, the cam  38  is fixed. The wind causes the wind blade  43  to drive the transmission shaft  35  to rotate. When the transmission shaft  35  rotates, the wind blade  43  will move with the wind direction. If the blade is vertical to the wind direction, a maximum wind force is obtained. If the wind blade  43  is reversed with the wind direction, it will be horizontal with the wind direction, then a minimum wind resistance is obtained. FIGS. 4,  5  and show the swing way of the wind blade and the wind direction. 
     FIG. 4 is a schematic view showing the wind direction and the swinging way of the wind blade  43 . As the transmission shaft  35  rotates, the wind blade  43  is supported by a bearing  42 , which may rotate to be vertical to the wind direction. The wind blade  43  reversing the wind direction  51  rotates to be horizontal. The swinging of the wind blade  43  is controlled as that shown in FIGS. 5 and 6. 
     FIG. 5 is an expansion view of cam groove. The central line  61  in FIG. 5 represents one half of the cam groove. The cam groove may allow a pulley to move therewithin. When the pulley moves to a descending groove  62 , the pulley will descend. When the pulley moves to a lifting groove  63 , the pulley will be lifted. 
     In FIG. 6, the linkage  39  is connected to a crank  72  through a fulcrum  73 . The crank  72  is supported by a supporting shaft  40 , and the fulcrum  70  serves as a rotary shaft. The supporting shaft  40  is fixed to the transmission shaft  35  shown in FIG.  3 . The linkage  39  and the crank  72  will rotate synchronously with the transmission shaft  35 . The fulcrum  71  is a sliding shaft moving within the cam groove of FIG.  5 . When the pulley shaft moves to the lifting groove  63  of FIG. 5, the fulcrum  71  will move to the point  75 , and the fulcrum  73  will move to the point  74 . Then, the linkage  39  moves to the position of the linkage  39 . The sleeve  44  is fixed to the wind blade  43 . The sleeve  44  is driven by the linkage  39 . Therefore, as the linkage  39  moves to the lifting position of the linkage  39 , the wind blade  43  moves to a position vertical to the wind blade  43 . Thus, the wind blade  43  is vertical to the wind direction and suffers a maximum force. As the fulcrum  71  moves to the descending groove  62  of FIG. 5, the linkage  39  will drive the wind blade  43  to be arranged horizontally. The extension  78  represents the assembling of the linkage  39  and the wind blade  43 . 
     In FIG. 3, there are three sets of assembly of linkage  39  and wind blade  43  which are spaced with an equal angle. Since the direction blade  37  will move along the wind blade to be fixed in one orientation cam  38  is fixed. Thus, when any assembly of the linkage  39  and the wind blade  43  moves to an orientation along the wind direction, the transmission shaft  35  will obtain power. As the transmission shaft  35  turns one circle, each wind blade will convert one wind energy. Finally, the power of the transmission shaft  35  is from an air power (compressing air, or absorption air) through the curved shaft  46  of the curved wheel  45 , a linkage  47  and a supporting shaft  48  to an air pump  49 . When the strength of the wind force is varied, the transmission shaft  35  will change the rotary speed. The air pump  49  changes the variation of rotary speed into the dynamic power of air. The number of assemblies of the wind blades  43  can be selected as required.

     When the sea level  121  in FIG. 7 rises, the pontoon  23  rises along the track  122  by the buoyancy of the pontoon. Through the linkage  86 , the linkage  88  will move counterclockwise a long the track  125 . Similarly, pontoon  25  will rise due to its buoyancy along a track  128 . Through the linkage  96 , the linkage  98  will move clockwise along the track  131 .

Through the linkage  96 , the linkage  98  will move counterclockwise along the track  131 . 
     In FIG. 7, the pontoon  23  moves along the track  122 , thus, it can match with the level change of sea tide to convert the energy of sea wave. The lowest water level allowable is at the position of point  123 , while the highest one is at point  124 , while the respect positions of the linkage  88  are point  126  and point  127 . Similarly, the pontoon  25  displaces along the track  128 , thus, it can match with the level change of sea tide to convert the energy of sea wave. The lowest water level allowable is at the position of point  129 . While the highest one is at point  130 , while the respect positions of the linkage  98  are point  132  and point  133 . 
     In FIG. 7, the displacement energies of the linkages  88  and  98  represents the converting energies of the pontoon  23  and pontoon  25  driving by the energy of sea tide. The transformation of these energies are shown in FIG.  8 .

The air pump  221  is fixed on the supporter  21 . The air energy is outputted from an air outlet  222 . 
     In FIG. 8, one end of a linkage  98  is a supporting shaft  97 , and another end thereof is engaged in shaft  224  by a bearing. Thus, the linkage  98  swings around the shaft  224 . Two ends of the shaft  224  are engaged on the supporter  21  by a bearing. The ratchet  225  is fixed on the shaft  224  and thus is operated synchronously. A palm  226  is assembled to a ratchet  225 , which are fixed to a linkage  98  by a supporting shaft  227 . As the linkage  98  swings clockwise, the palm  226  pushes the ratchet  225 .

The body is engaged on the shaft  224  by a bearing  234 . The palm  231  is assembled with the ratchet  230 , and is fixed on the linkage  98  by a supporting shaft  232 . As the linkage  98  swings counterclockwise, the palm  231  pushes the ratchet  230 . As the linkage  98  swings clockwise, the palm  231  released and swings back. The gear  233  drives the gear  235 . The gear  235  is engaged on the shaft  217  by a bearing. The gear  235  drives the gear  236 . The gear  236  and  237  are all fixed on the shaft  215 . The gear  237  is further engaged with the gear  238 . The gear  238  is fixed on the shaft  224 . A curved shaft  239  is placed on the gear  237 . By the curved rod  240  to drive the air pump  241  which is fixed on the supporter  21 , air energy is output from an air outlet  242 . 
     The linkage  88  and supporting shaft  87  in FIG. 8 is the linkage  88  and supporting shaft  87  in FIG.  7 . When the sea wave rises, the linkage  88  moves counterclockwise, the ratchet  203  will drive the gear  213  to push the air pump  221  through the gear  218  to generate air energy. Then, the gear  218  will drive the gear  216 , gear  214  and gear  211  so that the ratchet  208  move clockwise, while the palm  209  assembled therewith is in a releasing state. 
     When the sea wave descends, the linkage  88  swings clockwise, the ratchet  208  will drive the gear  211  to push air pump  221  through the gears  214 ,  216  and  218  to generate air energy. Then, the gear  218  also drives the gear  213  and ratchet  203 . The ratchet  203  moves counterclockwise, while the palm  204  assembled is in a releasing state. It is known that when the sea wave rises or descends, the gear  218  moves in the same direction. The amount of displacement of the sea wave is positive proportional to the rotary degree of the gear  218 . Therefore, the energy of air wave can be converted as energy of air by the air pump  221 . 
     The linkage  98  and supporting shaft  97  in FIG. 8 is the linkage  98  and supporting shaft  97  of FIG.  7 . As the sea wave rises, the linkage  98  moves clockwise, the ratchet  225  will drive the gear  238  to push the air pump  241  through the gear  237  to generate air energy. Then, the gear  237  also drives the gears  236 ,  235  and  233  so that the ratchet  230  rotates counterclockwise and the palm  231  assembled is in a releasing state. 
     When the sea wave descends, the linkage  98  swings counterclockwise, the ratchet  230  will drive gear  233  to drive the air pump  241  through gears  235 ,  236  and  237  so as to generate air energy. Then, the gear  237  drives the gear  238  and ratchet  225 , and the ratchet  225  rotates clockwise, while the palm  226  assembled is in a releasing state. It is known, whenever the sea wave rises or descends, the gear  237  may operate in the same direction. The amount of displacement of sea wave is positively proportional to the rotation of the gear  237 . Thus, the energy of sea wave all can be converted into the energy of air by the air pump  241 .

One end of the water tube  330  is connected to the upper portion of the water box  324  through a check valve  5 , while another end thereof is connected to the water  6  in the water source  332 . One end of the check valve  328  is connected to the water tube  330 , while another end thereof is connected to other water box in other set through an extension  329 . One end of the air valve  333  is connected to the air tube  309 , while another end thereof is connected to an air storing tank  7  through an air tube  334 . One end of the air valve  335  is connected to the air tube  334 , while another end thereof is connected to other air tubes in other sets through an extension  336 . The air valve  338  has one end connected to the air storing tank  7 , while another end thereof is connected to a high pressure air source (such as air pumps in FIGS. 6 and 8) through an extension  339 . 
     The water  6  in FIG. 9 is at atmosphere pressure and has a level higher than that of the water box  324 . When the water in water box  324  is in a low level, the air valve  325  is opened and communicates with atmosphere, and the air valve  326  is closed, thus water  6  flows into the water box  324 . After water is full, the air valve  325  closes, and air valve  326  is opened, then the high pressure air in air tube  309  will flow into the water box  324  so that the water box  324  is in high pressure. Then, the check valve  5  is closed. If water in water box  319  is in lower level, then it is in atmosphere pressure, thus, the check valve  323  is opened, and the water in water box  324  flows to the water box  319  through the check valve  323  and the water tube  322 . The energy of difference of the water levels of water boxes  319  and  324  are equal to the energy of difference of air pressures thereof. When the water in water box  324  is lowered to a low level again, the air valve  325  is opened and is communicated with atmosphere, and the air valve  326  is closed. Then, water  6  will flow into the water box  324  again. After water is full, the process is repeated. Similarly, the connecting tubes and processes in the water box  319 , water box  313  and water box  305  are identical, such functions are shown in FIGS. 10 and 11. 
     In FIG. 10, one end of the linkage  405  is fixed to the housing  401  through a supporting base  402  for swinging. Another end thereof is placed with a pontoon  407  at the lower edge and is connected to a pressing block  406  at the upper edge thereof. The pressing block  406  controls the switches  408  and  409 . The air valve  320  and air valve  321  are fixed on the housing  401 . The outlet of the air valve  320  is communicated with the outlet. The air valve  321  is connected to a high pressure source air tube  309  by a air tube  412 . Water flows into a water box through a water tube  414 . One end of the rope  415  is connected to the linkage  404 , while another end is connected to the pontoon  417  through the sliding base  423  of FIG.  11 . One end of the pontoon  417  is fixed to the housing  401  by a supporting base  416 . The check valve  318  is connected to the water outlet tube  317 . Water in water box flows out from the water outlet tube  317 . As the water in water box is in low water level, the pontoon  417  stops in point  418 . The linkage  405  and pontoon  417  stops in point  421 . The linkage  404  stops in point  424 . As the water in water box is full, the linkage  405  is hooked by the tilt surface  422  and is fixed on the upper layer. 
     In FIG. 10, as the water level in the water box is low, since the pontoon  417  has no buoyancy and thus, descends due to weight itself so as to stop in point  418  and thus to drive rope  415 . As shown in FIG. 11, the linkage  404  stops in point  424 , the linkage  405  will not be supported by the tilt surface  422  and then is descent to point  421 . Since the switches  408  and  409  are not pressed by the pressing block  406  and thus are released, thus, the air valve  320  is communicated with air and the air valve  321  is closed. When the water box is in atmosphere pressure, the water in water inlet tube  414  will flow into the water box when it is pushed by a high pressure air. 
     In FIG. 10, when the water in water box rises gradually, the pontoon  417  will rise by buoyancy, then the rope  415  will release. The linkage  404  will swing back to the original state around a supporting base  403  due to the weight of itself. 
     In FIG. 10, the water in water box rises to a full level, the pontoon  407  will rise due to the action of buoyancy. The linkage  405  will push the linkage  404  through the tilt surface  422  (shown in FIG.  11 ). As it passes through the tilt surface  422 , the linkage  404  returns to the original place. Then the linkage  405  is hooked by the tilt surface  422  and is fixed thereon. Meanwhile, the pressing block  406  on the linkage  405  will actuate the switches  408  and  409  so that the air valve  320  closes and the air valve  321  opens and is communicated with air tube  412 . Then the high pressure air in the high pressure source air tube  309  will flow into the water box so that the water in the water box is in high pressure. The water inlet tube  414  is connected to the check valve of a water tube in the next stage. Therefore, as the water box is in high pressure, the check valve will close. Since the water outlet tube  317  is connected to the water inlet tube in the previous stage. If the water box in the previous stage is in lower level, and is in atmosphere pressure, the water in the water outlet tube  317  flows into the water box in previous stage until the water in water box descends to a low level and the pontoon  407  descends, water is input again. 
     In FIG. 9, as the water box  324  in the lowest layer is in a full state, the high pressure air in the air tube  309  will flow into the water box to enforce the water in the water box will flow into the water box  319  through the check valve  323  and the water tube  322 . Similarly, as the water in water box  319  is in a full state, the high pressure air in the air tube  309  flows into the water box to enforce the water in water box to flow to the water box in previous stage through the check valve  312  and the water tube  311 . As the extension  316 , the number of water boxes can be selected as required. Finally, as the water box  305  is in a full state, the high pressure air in the air tube  309  will flow into the water box to enforce the water in the water box flows into the reservoir  2  through the check valve  304  and the water tube  3 . 
     In FIG. 12, the water tube  3  is connected to a check valve  504  at the lower portion of the water box  505  from the highest level of a reservoir  2 . Other than connecting tubes, others of the water box  505  are closed. The air valve  506 , air valve  507  and water tube  509  are connected to the upper portion of the water box  505 . The air tube  508  is connected to the air valve  507 . Another end of the water tube  509  is connected to the lower portion of the water box  511  through check valve  510 . The water box  511  is lower than that of the water box  505  with a distance. The air valve  512 , air valve  513  and water tube  514  are connected to the upper portion of the water box  511 . The air tube  508  is connected to the air valve  513 . Other than connecting tubes, others of the water box  511  are closed. The water tube  515  is connected to the lower portion of the water box  517  through a check valve  516 . The air valve  518  and air valve  519  are connected to the upper portion of the water box  517 . The air tube  508  is connected to air valve  519 . Other then connecting tubes, others of the water box  517  are closed. Extension  520  is connected to the water inlet tube in previous water box. The extension  521  is connected to the air tube  508 . One end of the air tube  522  is connected to the upper portion of the water box  517 , while another end thereof is connected to the lower portion of the water box  524  through a check valve  523 . The level of the water box  524  is lower than that of the water box  517  with a distance. The air valve  525  and air valve  526  are connected to the upper portion of the water box  524 . The air valve  526  is connected to the air tube  508 . One end of the water tube  528  is connected to the upper portion of the water box  524  through a check valve  527 . While another end thereof is connected to water  6  in the water source  332 . Other then connecting tubes, others of the water box  524  are closed. One end of the air valve  531  is connected to the air tube  508 , while another end thereof is connected to the a low pressure air barrel  535  through an air tube  532 . One end of the air valve  533  is connected to the air tube  532 , while another end thereof is connected to other tubes through extension  534 . One end of the air valve  535  is connected to the lower pressure air barrel  535 , while another end thereof is connected to a low pressure air source (such as air pumps in FIGS. 6 and 8) through an extension  536 . 
     Water  6  of FIG. 12 is in atmosphere pressure with a level lower than that of water box  524  with a distance. When the water in water box  524  is in low level, the air valve  525  is closed, and the air valve  526  is opened, then the air in the water box  524  will flow out through the air tube  508  so that the water box  524  is in low pressure. If the water in water box  517  is at atmosphere pressure, the check valve  523  will close, since the water  6  is in atmosphere pressure, the check valve  527  is opened. Thus, water  6  will flow into the water box  524 . After the water is full, the air valve  525  is opened, and the air valve  526  is closed, then the water within the water box  524  is in atmosphere pressure. Then, the check valve  527  is closed. Similarly, water in water box  517  is at low level, the air valve  518  is closed, and the air valve  519  is opened, then the air in the water box  517  will flow out through the air tube  518  so that the water box  517  is in low pressure. Then, the check valve  523  is opened. Since the water in water box  524  is in atmosphere pressure, the water flows into the water box  517  through the water tube  522 . After water is full, the air valve  518  is opened, and the air valve  519  is closed. Thus, the water in water box  517  is again in atmosphere pressure. The energy from the difference of water levels of the water box  517  and the water box  524  are equal to the energy from the difference of air pressures thereof. When water in the water box  524  is again reduced to a low level, the air valve  525  is closed, and the air valve  526  is opened, then water  6  will flow into the water box  524 . After water is full, the process is repeated. Similarly, the connecting tubes in the water box  511  and water box  505  are the same working processes, such as those shown in FIGS. 13 and 14. FIG. 13 has similar means as those in FIG.  10 . Only difference is the flowing way of air and air valves. The means of FIG. 14 are all identical to that of FIG.  11 . 
     In FIG. 13, one end of the linkage  605  is fixed to the housing  601  through a supporting base  602  for swinging. The lower edge of another end thereof is placed with a pontoon  607  and the upper edge thereof is connected to the pressing block  606 . The pressing block  606  actuates the switches  608  and  609 . The air valve  518  and air valve  519  are fixed to the housing  601 . The outlet of air valve  518  is communicated with atmosphere. The air valve  519  is connected to a lower pressure source  508  through an air tube  612 . Water flows into a water box through a water inlet tube  614 . One end of rope  615  is connected to a linkage  604 , and another end thereof is connected to the pontoon  617  through the sliding base  623  of FIG.  14 . One end of the pontoon  617  is fixed to the housing  601  by a supporting base  616  for swinging. The check valve  516  is connected to the water outlet tube  515 . Water in water box may flow out from the water outlet tube  515 . When the water in water box is in a low water level, the pontoon  617  stops in point  618 , and the linkage  605  and pontoon  617  stop in point  621 . The linkage  604  stops in point  624 . As the water in water box is in a full level, the linkage  605  is hooked by tilt surface  622  so as to stop at an upper layer. 
     In FIG. 13, as water in water box is in a low level, since the pontoon  617  has no buoyancy, it will descend by the weight itself as to stop in point  618 . Then the rope  615  is driven. As shown in FIG. 14, the linkage  604  stops in point  624 , then linkage  605  will not be supported by the tilt surface  622  and then descend to point  621 . Since the switches  608  and  609  are not pressed by the pressing block  606  and thus is released, the air valve  518  is closed, and air valve  519  is opened, then air in water box will flow into a low pressure source air tube  508  through the air tube  612  so that the water box is in a low pressure state. Meanwhile, the check valve  516  will close. When the air pressure within the water box is lower to a predetermined level, the water connected to the water inlet tube  614  and in atmosphere pressure will flow into the water box. 
     In FIG. 13, when the water in water box rises gradually, the pontoon  617  will rise due to buoyancy, then the rope  615  is released. Thus, the linkage  604  swings back around the supporting base  603  by the weight itself. 
     In FIG. 13, when the water in water box rises to a full level, the pontoon  607  will rise due to the action of buoyancy. As the linkage  605  passes through the tilt surface  622 , it will push away the linkage  604 , while as it has passed out of the tilt surface  622 , the linkage  604  will return to the original state. The linkage  605  is hooked by the tilt surface  622  and therefore is fixed thereon. At the same time, the pressing block  606  on the linkage  605  will actuate the switches  608  and  609  so that the air valve  518  is opened and the air valve  519  is closed. When the air valve  518  is opened, the air flows into the water box, so that the water in the water box is in the atmosphere pressure. The water inlet tube  614  is connected to the check valve of next water tube. Therefore, as the water in the water box is in atmosphere pressure, the check valve also closes (until the water in the water box is again reduced to a low level to present a low pressure state, the check valve is opened). Since the water outlet tube  515  is connected to the water inlet tube of the previous water box. If the water box in previous stage is in low level, the air pressure is in low pressure, thus, water in water outlet tube  515  flows into the previous water box until the water in water box is again reduced to a low level and the pontoon  607  descends, the water enters again. 
     In FIG. 12, as the water box  524  in the lowest layer is in low level, the water box  524  is communicated with the air tube  508  and is in low pressure, thus, the water  6  in water source  332  has a high pressure (atmosphere pressure), which will flow into the water box  524  through the water tube  528 . Similarly, as the water of water box  519  is in low level, the water box  519  will communicate with air tube  508  and thus is in a low pressure. Therefore, as the water box  524  in the next layer has a high pressure (atmosphere pressure), water flows into the water box  519  through the water tube  522 . As the extensions  520  and  521 , the number of water boxes can be selected as required. Similarly, as the water in the water box  511  is in a low level, the water box  511  is communicated with the air tube  508  to be in a low pressure, thus the water box in the next layer is in high pressure (atmosphere pressure), the water in water box will flow into the water box  511  through the water tube  514 . Similarly, the water in water box  505  is in a low level, the water box  505  is communicated with the air tube  508  so as to be in low pressure. Thus, the water box  511  in the next stage is in a high pressure (atmosphere pressure), water will flow into the water box  505  through the water tube  509 . When the water in water box  505  is full, the air valve  506  is opened to be in high pressure (atmosphere pressure), then, water in water box  505  will flow to the reservoir  2  through the check valve  504 .
