(a) TECHNICAL FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to an energy concentration device, and more particularly to an energy concentration device that comprises a pneumatic cylinder that allows for contact with waving sea water of the nature to make a float device to drive a piston rod to achieve an effect of up and down piston movement so as to realize an effect of pressurization of air inside the pneumatic cylinder, whereby the air may achieve an effect of increase of pressurization level through multi-staged pressurization and an effect of accumulation by being stored in a high-pressure air storage device for the purposes of electrical power generation with the pressurized air and supplying pneumatic power required by other applications, such as automobiles, motorcycles, buses, and factories and also for supplying of pneumatic power to household devices, such as household appliances and pneumatically-operating doors. 
       (b) DESCRIPTION OF THE PRIOR ART 
       [0002]    People have been aware of the use of hydraulic power and wind power since far ancient times and such powers are referred to as “old ways of renewable energy”. Since 1970, after the oil crisis, the use and development of new sources of energy (nuclear energy, wind energy, solar energy, and biomass energy) have been significantly progressed, leading human beings into a new milestone. With the creation of steam engines by Watt in 1759, human beings enter the steam age. Machines driven by coal brought a new way of energy that lead human civilization into the industrial age, where mass production brought wealth and comfortable living, but also caused a non-returning way of fate for the use of fossil energy caused various pollutions and global warming. In addition, the fossil energy is limited and lots of mining areas have already been or are going to be exhausted. On the other hand, renewable energies are generally unlimited. Although uranium based nuclear power generation is not considered belonging to fossil energy, yet the reserves of uranium is still limited. Thus, the fission based nuclear power is not considered a renewable energy. The importance and likelihood of nuclear power as being considered a renewable energy can only be emphasized after new breakthrough of the fusion based nuclear power occurs. Before the 19th century when the use of coal has been greatly advanced, all sorts of energy used are renewable energies and the general sources are human labor and animal power, and cattle, mules, horses, hydraulic milling and wind milling, and wood fires are commonly used. Fossil oil and natural gas did not gained their importance until 1900, and wind power and solar energy became important in 2010. Further, except unclear energy, tidal energy, and geothermal energy, the basic supply of energy for human activities is generally obtained from sunlight. Other energies, such as wind power, hydraulic power, and ocean flows, are also the result of sunlight heating air and water of the Earth. 
         [0003]    The advance of modern society makes consumption of electrical power by human beings increased so that the conventional way of power generation no longer suffices to meet the need of the general consumers and may suffer continuous rise of power generation cost. Consequently, power generation has changed from the traditional way to new ways that are based on renewable energy sources. Power generation with renewable energy sources includes hydraulic energy, solar energy, geothermal energy, ocean energy, and wind power, among which ocean energy includes tidal energy, wave energy, and ocean flow energy. The electrical energy generated with these renewable energy based electrical power generation can be stored for subsequent use or may be directly used after generation. 
         [0004]    A common way of storing or accumulating the electrical power generated with renewable energies is to stored the electrical power in a power storage device, such as a rechargeable battery, to achieve the purpose of collection and storage of electrical power. Although the rechargeable battery may receive and store the electrical energy generated with the renewable energies up a maximum level of 100%, yet the rechargeable battery, after being stored for a period of time, may readily discharge the electrical power so that when a user later attempts to use the electrical power stored in the rechargeable battery, there is only about 70%-80% of the total electrical power left in the battery. This is a natural way of energy loss and all the electrical power may eventually get totally lost with the lapse of time, leading to an unexpected consequence that the rechargeable battery is powerful enough to supply electrical power as scheduled to an electronic or electrical device when a user attempts to provide electrical power to the electronic or electrical device. Under such a condition, an additional or spare rechargeable battery may be needed for backup purposes in order to achieve expected supply of electrical to the electronic or electrical device. 
         [0005]    Thus, the present invention aims to provide a solution to overcome or alleviate the above-discussed issues and problems.

         [0031]    wherein each of the pneumatic cylinders  10  and each of the pressurization barrels  20  are grouped together as a pressurization system  90 ; the pressurization systems  90  are connected in a horizontal direction to each other in a serial connection manner; each of the pneumatic cylinders  10  is provided with a protection enclosure  17  and the protection enclosure  17  is provided in each of four internal corners thereof with a support post  171  with each of the support posts  171  coupled to an inner top end of the protection enclosure  17 ; and 
         [0032]    wherein the float device  14  is contactable with waving sea water of the nature to cause the float device  14  to drive the piston rod  132  to achieve up-and-down piston movement. 
         [0033]    The first one-way valves  11 ,  21 ,  301  are ingress-allowed egress-prohibited one-way check valves. 
         [0034]    The second one-way valves  12 ,  22 ,  302  are egress-allowed ingress-prohibited one-way check valves. 
         [0035]    Referring to  FIGS. 2 and 3 , each of the pneumatic cylinders  10  and each of the pressurization barrels  20  are grouped together as a pressurization system  90 . The pressurization systems  90  are connected in a horizontal direction to each other in a serial connection manner. Thus, in an initial condition, the piston device  13  of the front-most one of the pneumatic cylinders  10  receives a supply of external air through the air inlet tube  15  so that the interior of the piston device  13  is full or air thereby providing the interior of the piston device  13  with a predetermined air pressure. For example, considering the interior air pressure of the front-most one of the pneumatic cylinders  10  is 0 pound, with the piston device  13  comprising therein the piston rod  132  and an opposite end of the piston rod  132  provided with the float device  14 , when the present invention is placed on a sea surface or at a seashore, the float device  14  is driven by sea water that waves and thus contacts the float device  14  in such a way that the float device  14  is forced to reciprocally move up and down by the waving of the sea water. As such, the float device  14  drives the piston rod  132  to perform up and down piston movement within the piston device  13  and at the same time, air in the interior of the piston device  13  is subjected to an effect of up and down air pressurization, whereby the pressurized air is conducted through the air outlet tube  16  to an interior of the pressurization barrel  20 . Further, with the top  101  and the bottom  102  of the piston device  13  and the air inlet tube  15  and the air outlet tube  16  being respectively provided therebetween with the first one-way valves  11  and the second one-way valves  12  and the first end  201  and the second end  202  of the pressurization barrel  20  being respectively provided with the first one-way valve  21  and the second one-way valve  22  and the first one-way valves  11 ,  21  and the second one-way valves  12 ,  22  being ingress-allowed, egress-prohibited valves and egress-allowed, ingress-prohibited valves, when air flows through the first one-way valves  11 ,  21  and the second one-way valves  12 ,  22 , no reverse flow may occur and the pressurized air can be reliably preserved in the pressurization barrel  20 . And, with air being pressurized by the up and down piston movement of the piston rod  132  of the piston device  13 , the air pressure of the interior of the pressurization barrel  20  may be raised through the pressurization to 10 pounds. Thus, when the air pressure inside the pressurization barrels  20  reaches 10 pounds, the air having an air pressure of 10 pounds can be conveyed to a rearward one of the pneumatic cylinders  10  to be further compressed by the piston device  13  to reach an air pressure of 20 pounds inside the rearward pressurization barrel  20 , and so on, whereby through the piston movement achieved with the piston device  13  of the next rearward one of the pneumatic cylinders  10  to pressurize air, an air pressure that is desired by a user may be reached and the so pressurized air can be stored in the high-pressure air storage device  30  for subsequent use by the pneumatic power device  50  to generate electrical power that is then supplied to all sorts of household appliances and transportations that need electrical power. On the other hand, referring to  FIG. 4 , a second embodiment of the present invention is shown, in which according to different needs of users, two groups of serial-connection based pressurization systems  90  can be provided, where each group of the pressurization system  90  can feed pressurized air into the high-pressure air storage device  30  and the number of the high-pressure air storage device  30  may be more than one to suit the need of a predetermined level of pressure.

         [0040]    wherein each of the pneumatic cylinders  10  and each of the pressurization barrels  20  are grouped together as a pressurization system  90  and each of the pressurization system  90  is coupled through vertical stacking on each other; each of the pneumatic cylinders  10  is provided with a protection enclosure  17  and the protection enclosure  17  is provided in each of four internal corners thereof with a support post  171  with each of the support posts  171  extending through an inner top end of the protection enclosure  17  so that the support posts  171  function as rails along which movements can be made;

         [0042]    Referring to  FIG. 5 , the protection enclosure  17  of the present invention may be further provided with a coupling device  19 ; an end of the coupling device  19  is provided with a bearing portion  191  and an opposite end of the coupling device  19  is provided with an engagement element  192 ; the support post  171  is provided with a plurality of recesses and the recesses are engageable with the engagement element  192  in order to provides an effect of positioning, whereby with the coupling device  19  of the protection enclosure  17  comprising the bearing portion  191 , when the lowermost one of the float devices  14  is hit by sea waves, the float device  14  is moved upward to get into contact with the bearing portion  191  of the coupling device  19  and with the bearing portion  191  being so contacted, the engagement element  192  disengages from the recesses of the support post  171  and under this condition, when the hitting force of the sea waves reaches a predetermined level, the bottommost one of the protection enclosures  17  moves upward along the support post  171  so as to cause a cushioning device  18  to contact the upper float device  14  and the bearing portion  191  of the coupling device  19  of the protection enclosure  17  thereof to achieve an effect of two-staged air pressurization and so on.
