Description

[Technical field]

[0001] The present invention relates to a device for compressing a fluid, and more particularly to a fluid compressor capable of compressing a fluid by utilizing seawater pressure. [Background technology]

[0002] In recent years, clean power sources that do not use fossil fuels and are environmentally friendly, such as solar and geothermal power generation and hydrogen fuel cells, have been attracting attention. Among these, power sources that use seawater can utilize wave power and water pressure, and various methods have been considered. However, since power generated from natural energy sources is constantly changing depending on various conditions in the surrounding environment, such as weather, topography, time of day, etc., it has been difficult to maintain a stable output. Therefore, there was a need for a power structure that could utilize seawater, which is less affected by the surrounding environment, and continue to provide stable power.

[0003] In order to solve the above problems, a technical proposal has been made as described in JP 2013-164059 A (Patent Document 1). That is, Patent Document 1 proposes a technical proposal to generate compressed air by the up and down movement of a piston connected to a float that moves up and down using wave energy. However, because it uses wave energy, which changes greatly depending on weather changes, etc., there is an unevenness in the amount of compressed air generated by the float, making it difficult to provide a stable output at all times, and the above problems have not yet been solved.

[0004] The applicant therefore came up with the idea of ​​creating a fluid compression mechanism using seawater, and focused on a piston that can move up and down using seawater pressure. He developed a fluid compressor that can compress fluid by using multiple underwater pistons that move up and down due to seawater pressure in conjunction with each other, which has led to the proposal of the "fluid compressor" of the present invention.

[0005] [Patent Document 1] JP 2013-164059 A Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above problems, an object of the present invention is to provide a fluid compressor capable of compressing a fluid by a subsea piston that moves up and down due to seawater pressure. [Means for solving the problem]

[0007] In order to solve the above problems, the fluid compressor according to the present invention comprises a compression unit and a sliding unit. The compression unit comprises a compression tube having a hollow portion, extending substantially perpendicular to the sea surface, with a closed top surface and an open bottom surface, a compression head that closes the bottom surface of the compression tube and slides up and down inside the compression tube, a supply pipe capable of introducing a fluid to be compressed into a hollow portion between the top surface of the compression tube and the compression head, and a delivery pipe capable of delivering the fluid compressed by the sliding of the compression head to a subsequent stage. The sliding unit comprises a compression tube having a hollow portion, extending substantially perpendicular to the sea surface, with a closed top surface and an open bottom surface, a compression head that closes the bottom surface of the compression tube and slides up and down inside the compression tube, a supply pipe capable of introducing a fluid to be compressed into a hollow portion between the top surface of the compression tube and the compression head, and a delivery pipe capable of delivering the fluid compressed by the sliding of the compression head to a subsequent stage. The compression head in the compression unit is composed of a sliding tube that extends approximately perpendicular to the surface and has closed top and bottom surfaces, a sliding head that slides up and down within the sliding tube, a sliding rod that is provided on the upper surface of the sliding head, extends upward and is connected to the bottom surface of the compression head, a sliding water inlet that can introduce seawater from outside the sliding tube into the hollow space between the bottom surface of the sliding tube and the bottom surface of the sliding head, and a sliding water outlet that discharges seawater that has flowed into the sliding tube to the outside. A piston mechanism in the sliding unit that is operated by seawater pressure slides the compression head in the compression unit.

[0008] In addition, the present invention is configured such that a push-up plate is provided below the sliding unit, and one or more push-up units are arranged below the push-up plate, and the push-up unit is composed of a push-up pipe having a hollow portion, extending approximately perpendicular to the sea surface and having closed top and bottom surfaces, a push-up head that slides up and down within the push-up pipe, a push-up rod that is provided on the upper surface of the push-up head, extends upward and is connected to a predetermined location on the bottom surface of the push-up plate, a push-up water inlet that can introduce seawater outside the push-up pipe into the hollow portion between the bottom surface of the push-up pipe and the bottom surface of the push-up head, and a push-up water outlet that discharges seawater that has flowed into the push-up pipe to the outside, and a means is adopted in which the push-up plate is pushed up by the push-up unit, causing the sliding unit to rise.

[0009] Furthermore, the present invention employs a means in which a drainage tank in which seawater drained from the sliding unit and the push-up unit is stored via a drain pipe is disposed downstream of the push-up unit, an air tank is provided in the sea and stores air that remains in the drainage tank and is discharged as seawater flows in, and a power generation unit that generates power using the air stored in the air tank. Effect of the Invention

[0010] According to the fluid compressor of the present invention, the piston of the sliding unit slides upward due to the increased water pressure caused by seawater flowing into the hollow part of the sliding tube, and the compression head in the compression tube connected to the piston moves upward. This makes it possible to cover the energy required to compress the fluid stored in the hollow part of the compression tube with stable natural energy, that is, seawater pressure, thereby achieving the unprecedented excellent effect of contributing to energy savings in the entire operation and stabilization of output.

[0011] Furthermore, according to the fluid compressor of the present invention, by arranging a boost plate and a boost unit below the sliding unit, the sliding unit itself can be pushed up by operating the boost unit, thereby providing the excellent effect of more powerful compression of the fluid in the compression pipe.

[0012] Furthermore, according to the fluid compressor of the present invention, a drainage tank, an air tank, and a power generation unit are provided downstream of the boost unit, so that it is possible to generate electricity using the seawater that flows in for fluid compression. Part of This has the excellent effect of contributing to energy conservation by using it as a fuel cell. [Brief description of the drawings]

[Figure 4] FIG. 4 is an explanatory diagram showing another embodiment of a fluid compressor according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The greatest feature of the fluid compressor according to the present invention is that the fluid stored in the compression pipe is compressed by the seawater pressure using a piston mechanism that moves up and down due to seawater pressure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a fluid compressor according to the present invention will be described with reference to the drawings.

[0015] The fluid compressor according to the present invention is not limited to the embodiments described below, and can be modified as appropriate within the scope of the technical concept of the present invention, i.e., within the scope of shapes, dimensions, materials, etc. that can achieve the same functional effects.

[0016] A fluid compressor 1 according to the present invention will be described with reference to the drawings. Fig. 1 is an explanatory diagram showing an embodiment of a fluid compressor according to the present invention, in which (a) shows a state in which a fluid is flowing into a compression unit, and (b) shows a state in which the fluid is compressed by the operation of a sliding unit. FruitFIG. 3 is an explanatory diagram showing another embodiment of the fluid compressor according to the present invention, and more specifically, shows the installation of the compression unit, the sliding unit, the boost plate, and the boost unit. FIG. 3 is an explanatory diagram showing another embodiment of the fluid compressor according to the present invention, and more specifically, shows the simplified operation of the compression unit, the sliding unit, the boost plate, and the boost unit, where (a) shows a state in which the compression unit is filled with fluid, (b) shows a state in which the fluid is compressed by the sliding unit, and (c) shows a state in which the boost unit and the boost plate raise the sliding unit and further compress the fluid. FIG. 4 is an explanatory diagram showing another embodiment of the fluid compressor according to the present invention, and more specifically, shows the installation of the drain tank, the air tank, and the power generation unit disposed downstream of the boost unit. A fluid compressor 1 according to the present invention is basically constituted mainly by a compression unit 2 and a sliding unit 3.

[0017] The compression unit 2 is a unit that stores a fluid, compresses it, and sends it to the subsequent stage. The fluid is compressed by the sliding unit 3, which is disposed below the compression unit 2 and serves as a fluid compression means, sliding up and down. The compression unit 2 is installed in an offshore facility, and the sliding unit 3 is disposed in the sea below the compression unit 2, and since the sliding unit 3 slides upward to compress the fluid, it is necessary to install the sliding unit 3 at a location having a predetermined depth at which it can be disposed. There are no particular limitations on the fluid compressed by the compression unit 2, but possible modes include compressing air, carbon dioxide, LP gas, etc., and turning it into compressed air, dry ice, liquefied gas, etc., and sending it to a downstream stage. The compression unit 2 is composed of a compression pipe 10 having a supply port 13 and a delivery port 15 , and a compression head 11 disposed inside the compression pipe 10 and having a bottom surface connected to the sliding unit 3 .

[0018] The compression pipe 10 is a tubular body that constitutes the compression unit 2, and has a compression head 11 disposed inside the hollow portion. The compression tube 10 is a tubular body having a hollow portion, and the top surface of the compression tube 10 is entirely closed so that the compression head 11 slides upward by the upward sliding of the sliding unit 3 to compress the fluid stored in the hollow portion. The bottom surface of the compression tube 10 is partially or entirely open so as not to impede the operation of the compression head 11 which slides up and down. The shape and length of the compression tube 10 are formed in a substantially cylindrical shape with an inner diameter (slightly larger than the outer diameter of the compression head 11 provided in the hollow portion) within which the compression head 11 can slide, and the compression tube 10 is formed to have a total length approximately equal to or greater than the vertical sliding distance of the sliding unit 3 connected to the compression head 11. At a predetermined position above the compression pipe 10, there are provided a supply port 13 through which the fluid to be compressed can flow into the hollow portion, and a delivery port 15 through which the fluid compressed by the upward sliding of the compression head 11 can be delivered to a downstream facility, and the fluid can be introduced, compressed, and delivered automatically or manually. In addition, by installing the compression pipe 10 in a state where it extends approximately vertically to the sea surface, the pressure from the piston mechanism provided in the sliding unit 3 is transmitted directly to the compression head 11, making it possible to compress the fluid smoothly.

[0019] The supply port 13 is for allowing a fluid to flow into the hollow portion of the compression tube 10, more specifically, for allowing a fluid to flow between the closed top surface of the compression tube 10 and the top surface of the compression head 11 provided in the hollow portion. After the fluid is introduced into the hollow portion from the supply port 13, the hollow portion is sealed by closing the supply port 13 with a valve structure or other means. In this state, the hollow portion is compressed by sliding the compression head 11 upward, and the fluid stored in the hollow portion is compressed at the same time. The position of the supply port 13 is not particularly limited, but for example, when carbon dioxide, which is heavier than air, is caused to flow into a hollow portion blocked by the compression tube 10 and the compression head 11, providing the supply port 13 on the top surface or upper part of the side surface of the compression tube 10 allows the carbon dioxide to flow from above the compression tube 10 toward the top surface of the compression head 11, making it possible to prevent backflow of the introduced carbon dioxide. In addition, the supply port 13 is naturally connected to the supply pipe 12, and the fluid flows from the supply pipe 12 through the supply port 13 into the hollow portion of the compression tube 10.

[0020] The outlet 15 is for sending the fluid compressed in the hollow part of the compression pipe 10 to a downstream facility, and more specifically, for sending the compressed fluid, which is the fluid stored in the hollow part of the compression pipe 10 and compressed by the upward sliding of the compression head 11, to a downstream facility. During the compression operation into the hollow part by the sliding unit 3 and the compression head 11, the hollow part is sealed by closing it by means of a valve structure or the like, similar to the supply port 13. Then, by opening the outlet 15 upon completion of the compression operation, the fluid at high pressure is sent to the downstream facility. The position of the delivery outlet 15 is not particularly limited, as with the supply port 13, but since the fluid compressed by the upward sliding of the compression head 11 is delivered, the delivery of the compressed fluid present in the hollow portion can be well balanced by providing the delivery outlet 15 above the upper limit position of the compression head 11, preferably at approximately the center of the top surface. Also, the delivery outlet 15 is naturally connected to a delivery pipe 14, and the compressed fluid is delivered from the hollow portion through the delivery outlet 15 to the delivery pipe 14 and provided to a downstream facility.

[0021] The compression head 11 is a piston member provided in the hollow portion of the compression tube 10, and the bottom surface of the compression head 11 is connected to the sliding unit 3 so that the compression head 11 slides up and down vertically within the hollow portion. The compression head 11 is substantially cylindrical in shape, and although there is no particular limit to the length (total height) from top to bottom, it has an outer shape that is slightly smaller in diameter than the inner diameter of the compression tube 10 to the extent that it can slide in the hollow part of the compression tube 10. In this case, it is preferable to ensure watertightness by providing a water leakage prevention means, such as one or more piston rings in sliding contact with the upper outer peripheral wall of the compression head 11, so that the fluid stored above the compression head 11 does not leak below the compression head 11 through the small gap between the compression head 11 and the compression tube 10. In addition, by making the inside of the substantially cylindrical compression head 11 hollow to reduce its weight, it is possible to reduce the pressure load on the piston mechanism provided in the sliding unit 3 during the compression operation.

[0022] The sliding unit 3 is a tubular body having a sliding piston mechanism 25 installed therein, and causes the sliding piston mechanism 25 to slide up and down by supplying and discharging seawater from the bottom surface portion. The sliding unit 3 is disposed in a state where the entire sliding unit 3 is submerged in the sea as shown in Fig. 1, or in a state where the upper part of the sliding unit 3 is submerged in the sea so as to be above the sea surface (not shown). There is no particular limitation on the disposition means, and for example, a mode in which a base is installed at a required height from the seabed and the sliding unit 3 is fixedly placed on the base, or a mode in which the side wall of the sliding unit 3 is fixedly connected to the offshore facility on which the compression unit 2 is installed, etc. are conceivable. In addition, there is no particular limitation on the number of installations, but it is determined based on the required pressure for the fluid to be compressed by the compression unit 2. The sliding unit 3 is composed of a sliding tube 20, a sliding piston mechanism 25 provided in the hollow portion of the sliding tube 20, and a sliding water inlet 23 and a sliding water outlet 24 provided in the bottom portion.

[0023] The sliding tube 20 is a tubular body that constitutes the sliding unit 3, and has a sliding piston mechanism 25 disposed in its hollow portion. The sliding tube 20 is a tubular body having a hollow portion, and the top surface of the sliding tube 20 is partially or entirely open so that the sliding piston mechanism 25 can move up and down, and the bottom surface of the sliding tube 20 is closed to store the inflowing seawater. Regarding the shape and length of the sliding tube 20, the sliding tube 20 is formed in a substantially cylindrical shape with an inner diameter (slightly larger than the outer diameter of the sliding head 21 described later) that allows the sliding head 21 to slide, and is formed to have a total length longer than the upward movable distance that can exert the necessary pressure on the fluid stored in the compression unit 2. A sliding water inlet 23 that allows seawater to flow into the hollow portion and a sliding water outlet 24 that allows seawater that has flowed into the hollow portion to flow out are provided at specified locations on the bottom surface. By automatically or manually supplying and draining seawater, a sliding piston mechanism 25 installed inside the hollow portion slides up and down. The sliding pipe 20 is installed in a state where it is extended approximately vertically to the sea surface, so that when the sliding water inlet 23 opens, the sliding piston mechanism 25 installed inside the hollow portion is pushed up, and seawater automatically flows in up to the vicinity of the sea surface.

[0024] The sliding water inlet 23 is a hole for allowing seawater to flow into the hollow portion of the sliding tube 20, more specifically, a hole for allowing seawater to flow between the closed bottom surface of the sliding tube 20 and the sliding piston mechanism 25 provided in the hollow portion. By allowing seawater to flow into the hollow portion from the sliding water inlet 23, the seawater pressure pushes the sliding piston mechanism 25 upward. The water level of the seawater that has flowed into the hollow portion varies depending on the head pressure of the sliding tube 20 (the load applied to the sliding piston mechanism 25), but it can rise up to near the seawater level outside the sliding tube 20 or near the top surface of the sliding tube 20. Also, it is preferable that the sliding water inlet 23 employs a sliding water supply valve 26 that can be switched between open and closed, as shown in Fig. 1, so that the inflow of seawater can be switched between being stopped and being allowed to flow in. The position of the sliding water inlet 23 is not particularly limited, but since seawater is allowed to flow between the closed bottom surface of the sliding tube 20 and the sliding piston mechanism 25 to push up the sliding piston mechanism 25 from below, it must be provided at least in the lower region of the sliding tube 20, and more specifically, it is provided near the lower end of the bottom surface or side wall of the sliding tube 20. There is also no limitation on the size or number of the sliding water inlet 23, but a mode can be adopted in which the number of holes to be narrowed or opened can be limited so that the amount of seawater inflow can be adjusted automatically or manually. By adopting such a mode, it becomes possible to adjust the speed at which the sliding piston mechanism 25 moves upward.

[0025] The sliding drain port 24 is a hole for discharging seawater stored in the hollow portion of the sliding pipe 20 to the outside, and is provided at a predetermined position of the sliding pipe 20. By discharging seawater from the sliding tube 20 to the outside, the water level in the hollow portion is lowered, and the sliding piston mechanism 25 is lowered. A sliding drain pump 27 is connected to the sliding drain port 24, and when the sliding piston mechanism 25 is lowered, the seawater in the hollow portion is forcibly discharged to the outside. The position of the sliding drain port 24 is not particularly limited, but since the seawater between the closed bottom surface of the sliding tube 20 and the sliding piston mechanism 25 is discharged to act to lower the sliding piston mechanism 25, it is necessary to provide it at least in the lower region of the sliding tube 20, specifically, near the lower end of the bottom surface or side wall of the sliding tube 20. In addition, the size and number of the sliding drain ports 24 are not limited, and the descent speed of the sliding piston mechanism 25 can be adjusted by adjusting the amount of outflow over time by the sliding drain pump 27.

[0026] The sliding piston mechanism 25 provided in the sliding unit 3 is a sliding head 21 and a sliding rod 22 installed inside the sliding tube 20, and compresses the fluid through the compression head 11 connected to the upper end of the sliding rod 22 by sliding upward using seawater pressure. The sliding piston mechanism 25 is provided in the hollow portion of the sliding tube 20 and is composed of a sliding head 21 and a sliding rod 22. However, if a plurality of sliding tubes 20 are installed, each of them is naturally provided in the hollow portion of the sliding tube 20. Regarding the up and down sliding control of the sliding piston mechanism 25, the opening and closing operations of the sliding water inlet 23 and the sliding drain outlet 24 are performed manually or automatically, but there is no particular limitation on the control method. For example, a water level sensor may be provided in the hollow part of the compression unit 2, and the upward sliding distance based on the required pressure may be set as a program, so that after a predetermined amount of fluid is stored in the hollow part of the compression unit 2, the upward sliding operation is automatically performed in accordance with the program.

[0027] The sliding head 21 is a piston member provided in the hollow portion of the sliding tube 20, and slides up and down vertically within the hollow portion as the amount of seawater stored in the hollow portion between the bottom surface of the sliding head 21 and the bottom surface of the sliding tube 20 increases or decreases. The sliding head 21 is substantially cylindrical in shape, and although there is no particular limit to the length (total height) from top to bottom, it has an outer diameter slightly smaller than the inner diameter of the sliding tube 20 so that it can slide in the hollow part of the sliding tube 20. In this case, it is preferable to provide a water leakage prevention means such as one or more piston rings around the outer peripheral wall of the sliding head 21 to ensure watertightness so that seawater present below the sliding head 21 does not leak above the sliding head 21 through a small gap between the sliding head 21 and the sliding tube 20. In addition, it is also possible to adopt a mode in which the inside of the sliding head 21, which is substantially cylindrical, is hollow and filled with air, thereby reducing the weight of the sliding head 21 itself and amplifying its buoyancy. The lower end of the sliding rod 22 extending upward is fixed to the upper surface of the sliding head 21.

[0028] It is possible that seawater from the outside may flow in from the contact point between the top surface of the sliding tube 20 and the sliding rod 22 due to the sliding of the sliding rod 22 or a malfunction of the piston ring. For this reason, it is preferable that the sliding head 21, where the inflowing seawater accumulates, is provided in advance with a drainage path that penetrates from the top surface to the bottom and can drain seawater to the bottom of the sliding tube 20. By adopting such an embodiment, it is possible to prevent an increase in the mass of the sliding head 21 due to seawater accumulated in the top surface of the sliding head 21. In addition, the drainage path is naturally provided with a check valve that closes the drainage path during compression due to the inflow of seawater from the sliding water inlet 23. By adopting the above-mentioned drainage path in the boost unit 4 having a similar structure, it is possible to obtain the same effect, which contributes to energy saving of the entire fluid compressor 1.

[0029] The sliding rod 22 is a long rod-shaped body, and transmits the vertical movement of the sliding head 21 directly to the compression head 11 installed inside the compression unit 2. Thus, the upper end of the sliding rod 22 is connected to a predetermined location on the lower surface of the compression head 11, and the lower end of the sliding rod 22 is fixedly connected to a predetermined location on the top surface of the sliding head 21. This makes it possible to raise and lower the compression head 11 in conjunction with the vertical movement of the sliding head 21. The installation position of the lower end of the sliding rod 22 and the number of the sliding rods 22 are not particularly limited, and may be any position and number that can efficiently transmit the force generated by the vertical sliding of the sliding head 21 to the compression head 11. For example, if there is only one sliding rod 22, it is fixed to the approximate center of the top surface of the sliding head 21. Similarly, the installation position of the upper end of the sliding rod 22 and the number of the sliding rods 22 are not particularly limited, and may be any position and number that can efficiently transmit the force generated by the vertical sliding of the sliding head 21 to the compression head 11. In addition, the shape of the sliding rod 22 is not particularly limited, but the length is at least long enough that the lower surface of the compression head 11 does not contact the bottom surface of the compression tube 10 when the sliding rod 22 descends to the lowest position in the hollow part of the sliding tube 20, and the thickness is required to have a load strength that can withstand the resistance applied when compressing the fluid in the compression unit 2.

[0030] The operation of the fluid compressor 1 having the above components will be described with reference to FIG. 1(a) shows a state in which fluid has flowed into the compression unit 2 from the supply port 13. The compression head 11 is lowered, and most of the compression tube 10 is occupied by the fluid. First, seawater is injected from the sliding water inlet 23 of the sliding unit 3, and the seawater is injected into the area below the sliding head 21. As seawater is poured in, the sliding head 21 is pushed upward by the pressure of the seawater, and accordingly, the sliding rod 22 and the compression head 11 are pushed upward. 1(b) 。 The fluid is compressed by the above operation, as shown in Fig. 1 (b) . The compressed fluid is then delivered to the delivery pipe 14 through the delivery port 15.

[0031] As described above, according to this embodiment, by utilizing seawater pressure as the energy required for compressing the fluid, it contributes to energy saving in the fluid compression process.

[0032] The present invention The embodiment will be described with reference to Figs. 2 and 3. In the above embodiment, the compression unit 2 and the sliding unit 3 Only the components of As explained above, by using the push-up unit 4, the operation can be made even more effective. As shown in FIG. 2, the push-up unit 4 is located below the sliding unit 3, and the sliding unit 3 itself is pushed upward by the push-up unit 4, causing the compression head 11 connected to the sliding unit 3 to slide upward, thereby further compressing the fluid. The push-up unit 4 includes a push-up tube 30 and a push-up piston mechanism 35 .

[0033] As shown in FIG. 2 and FIG. 3, the push-up plate 5 is disposed at the bottom of the sliding unit 3, and the upper end of the push-up piston mechanism 35 in the push-up unit 4 is connected to the push-up plate 5 to assist in pushing up the sliding unit 3. but This is preferable. The push-up plate 5 used in this embodiment is a plate-like body provided on the bottom surface of the sliding tube 20, and the push-up plate 5 and the sliding unit 3 are raised and lowered by the up and down sliding of the push-up unit 4 connected to the bottom surface of the push-up plate 5, and the compression head 11 is also slid up and down. The shape of the boost plate 5 is not particularly limited, but may be, for example, a substantially rectangular plate-like body centered on the connection part with the sliding tube 20. The size of the boost plate 5 is also not particularly limited, but since the water pressure increases in proportion to the surface area of ​​the boost plate 5 and the force required to raise the boost plate 5 increases, it is desirable to have a mode in which the surface area is narrowed while taking into consideration the number and installation locations of the boost units 4 connected to the bottom surface of the boost plate 5. Furthermore, there is no limitation on the method of connecting the boost plate 5 to the sliding tube 20 and the boost plate 5 to the boost units 4, and they will be fixed by means of screwing using screws or welding or the like.

[0034] The push-up unit 4 is one or more tubular bodies each having a push-up piston mechanism 35 installed therein, and seawater is supplied and discharged from the bottom portion to slide the push-up piston mechanism 35 up and down, thereby pushing up the bottom surface of the push-up plate 5. The boost unit 4 is composed of a boost pipe 30, a boost head 31 and a boost rod 32 installed inside the boost pipe 30, and a boost water inlet 33 and a boost water outlet 34 provided on the bottom part of the boost pipe 30. There is no particular limitation on the shape of the boost pipe 30 used in the boost unit 4, but a mode in which one similar to the sliding pipe 20 used in the sliding unit 3 is used can be considered. When adopting such a mode, it is preferable that the boost piston mechanism 35 installed in the boost pipe 30 is also similar to the sliding piston mechanism 25. Furthermore, there is no particular limitation on the number of units to be installed, but it is determined based on the size of the boost plate 5 and the power required for the up and down movement of the boost plate 5. For example, as shown in FIG. 2, a mode in which a plurality of boost units 4 are connected to the boost plate 5 provided at the bottom of one sliding unit 3 can be considered. The boost unit 4 is disposed below the boost plate 5, and the upper end of the boost rod 32, which is a rod member of the boost piston mechanism 35, is connected to a predetermined location of the boost plate 5. There are no particular limitations on the means of disposition, but a preferred embodiment is one in which a base is installed at a required height from the seabed and the boost unit 4 is fixedly placed on the base. By fixing the bottom surface in this manner, the force generated by the vertical sliding of the boost piston mechanism 35 is applied only to the connection portion with the boost plate 5, which contributes to the efficient lifting of the boost plate 5.

[0035] The push-up pipe 30 is a tubular body that constitutes the push-up unit 4, and has a push-up piston mechanism 35 disposed inside the hollow portion. The boost pipe 30 is a tubular body having a hollow portion, and the top surface of the boost pipe 30 is partially or completely open to allow the boost piston mechanism 35 to move up and down, and the bottom surface of the boost pipe 30 is closed to store the seawater that flows in. Regarding the shape and length of the boost tube 30, it is formed in a roughly cylindrical shape with an inner diameter (slightly larger than the outer diameter of the boost head 31 provided in the hollow portion, described below) through which the boost piston mechanism 35 provided inside the boost tube 30 can slide, and is formed to have a total length that is equal to or greater than the distance required to push up the sliding unit 3 connected to the boost plate 5 and further compress the compression unit 2. A boost water inlet 33 that allows seawater to flow into the hollow portion and a boost water outlet 34 that allows seawater that has flowed into the hollow portion to flow out are provided at predetermined locations on the bottom portion, and a boost piston mechanism 35 provided inside the hollow portion slides up and down by automatically or manually supplying or draining seawater. In addition, the boost pipe 30 is extended substantially perpendicular to the sea surface and is installed substantially perpendicular to the bottom surface of the boost plate 5 provided at the upper stage, so that the upward pressure by the boost piston mechanism 35 provided in the boost unit 4 is directly transmitted to the boost plate 5, making it possible to smoothly push up the boost plate 5.

[0036] The boost water inlet 33 is a hole for allowing seawater to flow into the hollow portion of the boost pipe 30, and more specifically, is a hole for allowing seawater to flow between the closed bottom surface of the boost pipe 30 and the boost piston mechanism 35 provided in the hollow portion. Seawater is allowed to flow into the hollow portion from the boost water inlet 33, and the resulting seawater pressure pushes the boost piston mechanism 35 upward. The level of the seawater that has flowed into the hollow portion fluctuates depending on the head pressure of the boost pipe 30 (the load applied to the boost piston mechanism 35), but it can rise up to near the top surface of the boost pipe 30. It is also preferable that the boost water inlet 33 employs a boost water supply valve 36 that can be switched between open and closed, as shown in Figure 1, so that the inflow of seawater can be switched between on and off. The position of the boost water inlet 33 is not particularly limited, but since seawater is allowed to flow between the closed bottom surface of the boost pipe 30 and the boost piston mechanism 35 to push up the boost piston mechanism 35 from below, it must be provided at least in the lower region of the boost pipe 30, and more specifically, it is provided near the lower end of the bottom surface or side wall of the boost pipe 30. There is also no limitation on the size or number of the boost water inlet 33, but a mode can be adopted in which the number of holes to be narrowed or opened can be limited so that the amount of seawater inflow can be adjusted automatically or manually. By adopting such a mode, it becomes possible to adjust the speed at which the boost piston mechanism 35 moves upward.

[0037] The push-up drain outlet 34 is a hole that allows seawater stored in the hollow portion of the push-up pipe 30 to flow out, and is provided at a predetermined position of the push-up pipe 30. By discharging seawater from the boost pipe 30 to the outside, the water level in the hollow portion is lowered, and the boost piston mechanism 35 is lowered. Of course, a boost drain pump 37 is connected to the boost drain port 34, and when the boost piston mechanism 35 is lowered, the seawater in the hollow portion is forcibly discharged to the outside. The position of the boost drain outlet 34 is not particularly limited, but since the seawater between the closed bottom surface of the boost pipe 30 and the boost piston mechanism 35 is discharged to cause the boost piston mechanism 35 to descend, the boost drain outlet 34 must be provided at least in the lower region of the boost pipe 30, and more specifically, the boost drain outlet 34 is provided near the lower end of the bottom surface or side wall of the boost pipe 30. There is also no limitation on the size or number of the boost drain outlet 34, and the descending speed of the boost piston mechanism 35 can be adjusted by adjusting the amount of outflow over time by the boost drain pump 37.

[0038] The push-up piston mechanism 35 provided in the push-up unit 4 is a push-up head 31 and a push-up rod 32 installed inside the push-up tube 30, and pushes up the sliding unit 3 via the push-up plate 5 connected to the upper end of the push-up rod 32 by sliding upward using seawater pressure. The push-up piston mechanism 35 is provided within the hollow portion of the push-up tube 30 and is composed of a push-up head 31 and a push-up rod 32, but if multiple push-up tubes 30 are installed, then naturally each of them will be provided within the hollow portion of the push-up tube 30. Regarding the up and down sliding control of the push-up piston mechanism 35, the opening and closing operations of the push-up water inlet 33 and the push-up water outlet 34 are performed manually or automatically, but there is no particular limitation on the control method. For example, a water level sensor may be provided in the hollow part of the sliding tube 20 provided as the sliding unit 3, and the upward sliding distance based on the pressure required to push up the push-up plate 5 may be set as a program, so that after the compression operation to the compression unit 2 due to the inflow of seawater into the sliding tube 20 is completed, the upward sliding operation according to the program is automatically performed.

[0039] The push-up head 31 is a piston member provided in the hollow portion of the push-up tube 30, and slides up and down vertically within the hollow portion as the amount of seawater stored in the hollow portion between the bottom surface of the push-up head 31 and the bottom surface of the push-up tube 30 increases or decreases. The push-up head 31 is substantially cylindrical in shape, and although there is no particular limit to the vertical length (total height), it has an outer diameter that is slightly smaller than the inner diameter of the push-up tube 30 so that it can slide inside the hollow part of the push-up tube 30. In this case, it is preferable to ensure watertightness by providing a water leakage prevention means such as one or more piston rings around the outer peripheral wall of the push-up head 31 so that seawater present below the push-up head 31 does not leak above the push-up head 31 through the small gap between the push-up head 31 and the push-up tube 30. In addition, it is also possible to adopt a mode in which the inside of the substantially cylindrical push-up head 31 is hollow and filled with air, thereby reducing the weight of the push-up head 31 itself and increasing its buoyancy. The lower end of the push-up rod 32 extending upward is fixed to the upper surface of the push-up head 31.

[0040] The push-up rod 32 is a long rod-shaped body that directly transmits the up and down movement of the push-up head 31 to the push-up plate 5. Thus, the upper end of the push-up rod 32 is connected to a predetermined location on the bottom surface of the push-up plate 5, and the lower end of the push-up rod 32 is fixedly connected to a predetermined location on the top surface of the push-up head 31. This makes it possible to raise and lower the sliding unit 3 connected to the push-up plate 5 in conjunction with the up and down movement of the push-up head 31. There are no particular limitations on the installation positions of the lower ends of the push-up rods 32 or on the number of the push-up rods, so long as the force generated by the up and down sliding of the push-up head 31 can be efficiently transmitted to the push-up plate 5. For example, if there is only one push-up rod 32, it is fixed to approximately the center of the top surface of the push-up head 31. Similarly, there are no particular limitations on the installation positions of the upper ends of the push-up rods 32 or on the number of the push-up rods, so long as the force generated by the up and down sliding of the push-up head 31 can be efficiently transmitted to the push-up plate 5. In addition, there are no particular limitations on the shape of the push-up rods 32, but the length must be at least the length required for compression into a fluid performed by the sliding unit 3 that rises with the push-up against the push-up plate 5, and the thickness must have a load strength sufficient to withstand the water pressure applied to push up against the push-up plate 5.

[0041] The operation of the fluid compressor 1 composed of the above components will be described with reference to Fig. 2. Note that the operation of the compression unit 2 described with reference to Fig. 1 will be omitted. 2(a) shows a state in which fluid flows into the compression unit 2 from the supply port 13. The compression head 11 is lowered, and most of the compression tube 10 is occupied by the fluid. FIG. 2(b) shows a state in which seawater is injected into the sliding unit 3, causing the sliding piston mechanism 25 to rise, and the compression head 11 to be pushed up, thereby compressing the fluid in the compression pipe 10. The hollow portion of the sliding unit 3 is filled with seawater, and the sliding piston mechanism 25 is raised to the vicinity of the top surface portion of the sliding unit 3. Seawater is injected from the push-up water inlet 33 of the push-up unit 4. The seawater is injected into the area below the push-up head 31. As the seawater is poured in, the pressure of the seawater pushes the push-up head 31 upward. Accordingly, the push-up rod 32, the push-up plate 5, and the sliding unit 3 are pushed up, and the compression head 11 is further pushed up. This force causes the fluid to be compressed even more than in FIG. 2(b), as shown in FIG. 2(c). 2(c) 。 The fluid is compressed by the above operation, as shown in Fig. 2 (c) . The compressed fluid is then delivered to the delivery pipe 14 through the delivery port 15.

[0042] In this manner, according to this embodiment, the fluid compressed by the sliding unit 3 can be further compressed by the lifting action of the push-up unit 4, making it possible to compress fluids that require strong pressure, and by dividing the fluid compression process into two stages, the load on the sliding unit 3 and the push-up unit 4 can be distributed, which is an excellent effect.

[0043] Also, as shown in FIG. 3, a plurality of push-up units 4 may be provided for one sliding unit 3 to compress the fluid. After the fluid is compressed by the sliding unit 3, seawater is injected into the multiple push-up units 4 connected to the push-up plate 5, and each push-up piston mechanism 35 rises to lift the push-up plate 5. At this time, by making the inflow amount of seawater and the rise width of the push-up piston mechanism 35 uniform in each push-up unit 4, the upward force acting on the push-up plate 5 is smoothly transmitted to the sliding unit 3, and the compression of the fluid by the compression head 11 is efficiently performed.

[0044] In this way, according to this embodiment, the fluid compressed by the sliding unit 3 can be further compressed by the lifting action of the multiple push-up units 4, which has the excellent effect of reducing the burden on the push-up units 4 compared to the embodiment shown in Figure 2.

[0045] Another embodiment will be described with reference to Fig. 4. In the above-mentioned embodiment, only the structure was provided for compressing the fluid, but at the same time as the fluid is compressed, air and seawater are introduced and discharged from the hollow parts of the sliding unit 3 and the push-up unit 4. In this embodiment, the discharged air and seawater are used to generate wind power in the power generation unit 8, thereby aiming at effective energy circulation. As shown in FIG. 4, a drainage tank 6, an air tank 7, and a power generation unit 8 are arranged downstream of the fluid compressor 1, and wind power generation is performed by utilizing the pressure generated when the air stored in the air tank 7 is discharged.

[0046] As shown in the figure, in the case where the top surfaces of the sliding tube 20 and the push-up tube 30 are closed except for the openings necessary for the up and down movement of the piston mechanism, a sliding air inlet 28 and a push-up air inlet 38 (hereinafter sometimes simply referred to as "air inlet") are provided as air inlets that can admit the same amount of air as the discharge amount of seawater when discharging seawater stored in the hollow portion. Similarly, a sliding exhaust port 29 and a push-up exhaust port 39 (hereinafter sometimes simply referred to as "exhaust port") are also provided as exhaust ports that can release to the outside the same amount of air as the inflow amount of seawater when seawater is flowed into the hollow portion.

[0047] An air intake pipe capable of sucking in the atmosphere above the sea and supplying the air to the sliding pipe 20 and the boost pipe 30 is connected to the air intake port, and an air intake adjustment valve 50 equipped with a check valve is provided to prevent stagnant air from entering the air intake port. Although there is no particular limitation on the position of the air intake port in the sliding pipe 20 and the boost pipe 30, it is preferable that the air intake port is provided at least in the upper region in order to smoothly supply the atmosphere, and specifically, it is preferable that the air intake port is provided near the upper end of the top surface or side wall of the sliding pipe 20 and the boost pipe 30. Furthermore, there is no particular limitation on the size or number of the air intake port, but by making the diameter of the air intake port equal to or larger than that of the sliding drain port 24 and the boost drain port 34, the amount of seawater discharged from the hollow portion and the amount of air supplied from the air intake port become the same, which contributes to smooth discharge of seawater and inflow of air.

[0048] An exhaust pipe capable of discharging the air stored in the hollow parts of the sliding tube 20 and the boost tube 30 to the outside is connected to the exhaust port, and an exhaust adjustment valve 51 equipped with a check valve is provided so that the discharged air does not flow back into the hollow parts. The position of the exhaust port in the sliding tube 20 and the boost tube 30 is not particularly limited, but it is preferable that it is provided at least in the upper area in order to smoothly discharge the air in the hollow parts, and specifically, it is preferable that it is provided near the upper end on the top surface or side wall of the sliding tube 20 and the boost tube 30. The size and number of the exhaust port are also not limited, but by making the diameter of the exhaust port equal to or larger than that of the sliding water inlet 23 and the boost water inlet 33, the amount of seawater flowing into the hollow parts and the amount of air discharged from the exhaust port become the same, which contributes to smooth inflow of seawater and discharge of air. The air discharged from the sliding tube 20 and the push-up tube 30 through the exhaust port and exhaust pipe is sent to the hollow portion of the air tank 7 described below, and is stored as air to be used for wind power generation.

[0049] The drainage tank 6 is a tank that stores seawater discharged from the hollow portions of the sliding tube 20 and the push-up tube 30, sends the air in the drainage tank 6 to the downstream air tank 7, and further discharges the seawater stored in the drainage tank 6 to the outside, thereby supplying air from the atmosphere. The drainage tank 6 is a tank having a hollow portion capable of storing seawater, with the top and bottom closed, and is provided at predetermined locations with a seawater inlet 41 for flowing seawater discharged from the sliding pipe 20 and the push-up pipe 30 into the drainage tank 6, a seawater outlet 42 for discharging seawater in the drainage tank 6 to the outside, a seawater drainage pump 40, an air intake 43 for supplying air into the drainage tank 6, and an air outlet 44 for sending air in the drainage tank 6 to the downstream air tank 7. The shape and length of the drainage tank 6 may be any as long as it has a capacity capable of storing the seawater flowing in from the sliding pipe 20 and the push-up pipe 30, and specifically, a drainage tank 6 having a capacity that allows the total amount of seawater flowing into the hollow portions of the sliding pipe 20 and the push-up pipe 30 connected to the drainage tank 6 to be stored at the maximum.

[0050] The seawater inlet 41 is a hole for allowing seawater discharged from the sliding pipe 20 and the push-up pipe 30 to flow into the drainage tank 6 and be stored therein; more specifically, it is a hole that causes seawater discharged from the sliding drain outlet 24 and the push-up drain outlet 34 to be stored in the closed drainage tank 6, and acts to push up the air trapped in the drainage tank 6 from below. There is no particular limitation on the location where the seawater inlet 41 is installed, but since the top surface of the seawater inlet 41 is disposed at a position lower than the bottom surface of the push-up unit 4, it is preferable that it be installed at a location where seawater hanging down due to gravity can flow in, for example, at the upper part of the side wall of the drainage tank 6 or at a predetermined location on the top surface as shown in Fig. 4. In addition, by making the size of the seawater inlet 41 equal to or larger than the diameter of the sliding drainage outlet 24 and the push-up drainage outlet 34, seawater can flow in smoothly. As seawater flows into the drainage tank 6 through the seawater inlet 41, the total volume of seawater stored in the drainage tank 6 increases, and the air retained in the drainage tank 6 is compressed and sent from the air outlet 44 provided at the top of the drainage tank 6 to the downstream air tank 7. This action continues until the inflow of seawater from the sliding drain outlet 24 and the push-up drain outlet 34 is stopped or the seawater is discharged to the outside from the seawater outlet 42.

[0051] The seawater discharge outlet 42 is a hole for discharging the seawater stored in the drainage tank 6 to the outside, and more specifically, it is a hole for discharging the seawater stored in the drainage tank 6 to the outside while at the same time supplying air into the drainage tank 6 to cause it to remain there. Because the seawater stored in the drainage tank 6 will not be naturally discharged to the outside due to the head pressure, the seawater is discharged to the outside using a seawater drainage pump 40. The specific structure and specifications of the seawater drainage pump 40 may be any of those known in the art and are not particularly limited. The position of the seawater discharge port 42 is not particularly limited, but since the seawater stored in the drainage tank 6 is reduced by discharging the seawater in the drainage tank 6 to the outside, the seawater discharge port 42 must be provided at least in the lower region of the drainage tank 6, and specifically, is provided near the lower end of the bottom surface or side wall of the drainage tank 6. There is also no limitation on the size or number of the seawater discharge ports 42, but a preferred embodiment is one in which the seawater drainage pump 40 is provided with a drainage adjustment mechanism that can automatically adjust the amount of seawater discharged in conjunction with the up and down sliding of the piston mechanisms provided in the sliding unit 3 and the push-up unit 4. By adopting such an embodiment, it becomes possible to perform adjustments such as discharging seawater by the seawater drainage pump 40 when the piston mechanism slides upward, and stopping the seawater drainage pump 40 to store seawater when the piston mechanism slides downward. As the seawater discharge port 42 is opened and the seawater drainage pump 40 is operated, the seawater in the drainage tank 6 flows out, thereby reducing the total volume of seawater stored in the drainage tank 6 and allowing air to flow in through the air intake port 43 provided at the top of the drainage tank 6. This action continues until the seawater discharge port 42 is closed and the discharge of seawater is stopped or until the inflow of seawater from the sliding drainage port 24 and the push-up drainage port 34 begins.

[0052] The air intake port 43 is a hole for taking in air from the outside and supplying it into the drainage tank 6. More specifically, it is a hole for supplying an amount of air equal to the amount of seawater discharged into the drainage tank 6 and retaining it therein at the same time as the seawater stored in the drainage tank 6 is discharged to the outside. An air intake pipe capable of sucking in the atmosphere above the sea and supplying it to the drainage tank 6 is connected to the air intake port 43, and an air intake adjustment valve 50 equipped with a check valve is provided so that the air remaining in the drainage tank 6 does not enter the air intake pipe. Although there is no particular limitation on the position of the air intake port 43, it is preferable that the air intake port 43 is provided at least in the upper region of the drainage tank 6 in order to smoothly supply the atmosphere into the drainage tank 6, and specifically, it is preferable that the air intake port 43 is provided near the upper end of the top surface or side wall of the drainage tank 6. Although there is no particular limitation on the size or number of the air intake port 43, by making the diameter of the air intake port 43 equal to or larger than that of the seawater discharge port 42, the amount of seawater discharged from the seawater discharge port 42 and the amount of air supplied from the air intake port 43 become the same, which contributes to smooth inflow of seawater and supply of air.

[0053] The air outlet 44 is a hole for sending air stagnant in the drainage tank 6 to the air tank 7 arranged downstream, and more specifically, is a hole for sending the stagnant air from the drainage tank 6 to the air tank 7 arranged downstream as seawater flows into the drainage tank 6 from the seawater inlet 41. It is preferable that the air outlet 44 is provided with an exhaust control valve 51 that can be automatically or manually switched between open and closed. By adopting this embodiment, when air is sent to the downstream air tank 7, the timing of opening can be delayed to apply pressure to the air, and even if the air tank 7 is disposed below the drainage tank 6, the air can be normally sent by the applied pressure. In addition, the position of the air outlet 44 is not particularly limited, but since the air in the drainage tank 6 is sent to the downstream, it is necessary to provide the air outlet 44 at least in the upper region of the drainage tank 6, and specifically, it is provided near the upper end of the top surface or side wall of the drainage tank 6. In addition, the size and number of the air outlet 44 are not limited, but by making the diameter of the air outlet 44 equal to or larger than that of the seawater inlet 41, the amount of seawater flowing in from the seawater inlet 41 and the amount of air sent from the air outlet 44 become the same, which contributes to smooth inflow of seawater and supply of air. An air supply pipe extending into the hollow portion of the air tank 7 is naturally connected to the air supply port 44, and air is supplied from the drainage tank 6 to the air tank 7 via the air supply pipe.

[0054] The air tank 7 is a cylindrical tube having a hollow portion, the top surface of the air tank 7 is closed to store the incoming seawater and air, and the bottom surface of the air tank 7 is partially or entirely open to cover the air inlet 45 connected to the air supply pipes extending from the sliding exhaust port 29, the push-up exhaust port 39, and the air supply port 44. The shape of the air tank 7 is not particularly limited as long as it can store the air flowing in from the air inlet 45 near the top of the air tank 7, but may be, for example, a substantially cylindrical shape or a polygonal prism shape. The length of the air tank 7 is also not particularly limited as long as it has a capacity to store the air flowing in from the air inlet 45. As for the location of the air tank 7, it is installed at least underwater, since the air stored near the top of the air tank 7 in a compressed state by water pressure is discharged and the pressure is used to generate wind power. For example, if the air tank is installed at a depth of about 10 m, the stored air will be compressed to about half of the atmospheric air, making it possible to ensure the flow speed when the air is discharged. Seawater flows in from the open bottom of the air tank 7, filling the hollow part of the air tank 7 with seawater. Then, air flows in from the air inlet 45 provided in the hollow part of the air tank 7, so that air is stored in the upper part of the hollow part, and seawater in an amount equal to the volume of the stored air is automatically discharged to the outside from the open bottom of the air tank 7.

[0055] The air inlet 45 is a hole that allows air sent from the sliding tube 20, the push-up tube 30, and the drainage tank 6 to flow into the hollow portion of the air tank 7 via the air sending tube. The air inlet 45 is a hole provided for each air supply pipe arranged up to the hollow portion of the air tank 7. However, as shown in FIG. 4, a configuration in which multiple air supply pipes are merged into one air supply pipe and then arranged in the hollow portion of the air tank 7 is also suitable. The location of the air inlet 45 is not particularly limited as long as the air flowing into the air tank 7 does not leak out of the air tank 7, but one possible embodiment is to provide the air inlet 45 at approximately the center of the hollow part of the air tank 7 as shown in the figure. The size and number of the air inlet 45 are also not particularly limited, but by making the diameter of the air inlet 45 the same or larger as the air supply pipe disposed in the air tank 7, it is possible to expect an effect that air is supplied without unnecessary pressure when it is sent from the exhaust port or the air supply port 44 to the air inlet 45. The air flowing into the air tank 7 from the air inlet 45 rises through the seawater filled in the hollow portion of the air tank 7, and then remains in the upper part of the air tank 7.

[0056] The power generation air supply port 46 is a hole for supplying air remaining in the hollow portion of the air tank 7 to the power generation unit 8 via an exhaust pipe. There is no particular limitation on the location where the power generation air outlet 46 is installed, but it needs to be provided at least in the upper region of the air tank 7 in order to discharge the air stored in the air tank 7 toward the power generation unit 8, and specifically, it is desirable for it to be provided in approximately the center of the top surface of the air tank 7. Furthermore, although not shown, by forming a slope toward the power generation air outlet 46 on the top surface of the air tank 7 so that the air that flows in naturally accumulates toward the power generation air outlet 46, it becomes possible to efficiently discharge the air. Also, it is preferable to provide an exhaust pipe connected to the power generation air outlet 46 with an exhaust adjustment valve 51 as shown in the figure, so that a desired amount of air can be discharged automatically or manually. By adopting this embodiment, it is possible to discharge a fixed amount of air with a certain pressure, which has the excellent effect of enabling stable wind power generation in the power generation unit 8 provided downstream of the exhaust pipe. Furthermore, by making the diameters of the power generation air outlet 46 and the exhaust pipe smaller than the air inlet 45, it is possible to increase the amount of air stored in the air tank 7 and to increase the flow rate of air in the exhaust pipe.

[0057] The power generation unit 8 is provided at the rear of the air tank 7, and is a power generation facility that uses the pressure of the air discharged from the air tank 7 through an exhaust pipe. The power generation unit 8 may be any equipment that generates electricity by utilizing pressurized air supplied from the air tank 7. For example, a suitable embodiment is one in which multiple blades are provided inside the exhaust pipe and the rotational force of the blades is used to rotate a turbine generator to generate electricity. There is no particular limitation on the structure of the power generating unit 8, and for example, if the blade is a propeller type or a Savonius type, the shape is appropriately selected depending on the structure of the installation location. There is also no particular limitation on the turbine generator, and various conventionally known devices can be applied. Furthermore, there is no particular limitation on the installation location or the number of the power generating units 8. For example, in order to efficiently use the air pressure sent from the power generating air supply port 46, a first power generating unit 8 may be installed near the outlet of the exhaust control valve 51 where the air pressure discharged from the air tank 7 is the highest, and an orifice may be provided downstream of the power generating unit 8 to increase the air pressure, and a second power generating unit 8 may be installed in the rear stage. The air that has generated electricity by passing through the power generation unit 8 is discharged into the atmosphere via an exhaust pipe connected to the power generation unit 8.

[0058] There is no particular limitation on the use of the electricity generated by the power generation unit 8. For example, the electricity may be used to charge an external power source such as a battery, or may be used to power the sliding unit 3, the push-up unit 4, and the drainage pump provided in the drainage tank 6. Part of the power source It is possible to use the above-mentioned embodiment.

[0059] The operation of the fluid compressor 1 having the above-mentioned components will be described with reference to Fig. 4. Note that the power generation action in the sliding unit 3 (not shown) operates in the same manner as the power generation action in the push-up unit 4 (shown), and therefore a description thereof will be omitted. In the push-up unit 4, which performs compression action by the up-and-down sliding of the push-up head 31, when the push-up head 31 slides downward, seawater stored in the hollow portion of the push-up pipe 30 is discharged from the push-up drain outlet 34 toward the drain tank 6, and at the same time, air flows into the hollow portion of the push-up pipe 30 via the push-up air supply port 38. The air stored in the drainage tank 6 is compressed by seawater flowing into the drainage tank 6 from the upflow drain outlet 34, and is sent to the air tank 7 disposed underwater when the exhaust adjustment valve 51 is opened. After the air sent to the air tank 7 is stored in the hollow part of the air tank 7, the power generation air supply outlet 46 is opened, and power generation is performed in the power generation unit 8 using the wind power rising from the sea toward the sea surface. The air used for power generation continues to rise and is discharged into the atmosphere. In addition, when the boost head 31 slides upward, seawater flows into the hollow part of the boost pipe 30 from the boost water inlet 33, and at the same time, air stored in the hollow part of the boost pipe 30 is sent out from the boost exhaust outlet 39 to the air tank 7, and is used for generating electricity by the power generation unit 8 in the same manner as described above.

[0060] In this way, according to this embodiment, it is possible to use the air discharged during fluid compression for wind power generation, and it is also possible to send out air that can be used for wind power generation by using the inflow and outflow of air using the seawater discharged after fluid compression. As part of the power source for This contributes to energy saving of the entire fluid compressor 1.

[0061] The fluid compressor 1 according to the present invention is constituted by the above-mentioned components. In other words, the fluid compressor 1 of the present invention is composed of a compression unit 2 and a sliding unit 3, and is provided with a boost plate 5 at the bottom of the sliding unit 3 according to the pressure required for the fluid to be compressed in the hollow portion of the compression unit 2, and is also provided with a boost unit 4 capable of lifting the bottom of the boost plate 5.The fluid compressor 1 can be installed anywhere on the sea where the sliding unit 3 and the boost unit 4 can be installed, for example, at an offshore resource mining site or offshore, and will mainly compress the fluid that flows into the compression unit 2.

[0062] Although the basic configuration and operation / effects of the fluid compressor 1 according to the present invention have been described above, the present invention is not limited to the configuration shown in the above embodiment and drawings. For example, a configuration is also possible in which compressed gas that has become high temperature and high pressure in the compression unit 2 is cooled to room temperature by passing through a heat exchanger, and then passed through a pipe having multiple propellers installed therein to generate electricity in a power generating turbine, while the compressed gas with reduced pressure is sent to an air tank 7 to generate electricity again in the power generating unit 8, thereby increasing power generation efficiency and providing a stable power supply by passing through multiple power generating facilities.

[0063] As described above, according to the fluid compressor 1 of the present invention, the sliding head 21 is caused to slide upward by the water level and water pressure that increase due to seawater flowing into the hollow portion of the sliding unit 3, and the compression head 11 is caused to move upward via the sliding rod 22, thereby compressing the fluid filled in the compression unit 2, and the energy required for compressing the fluid can be compensated for by seawater pressure.

[0064] Air has the property of becoming hotter when compressed. Therefore, when air is used as the fluid to be compressed in the present invention, it is possible to use the increased temperature of the air caused by compression to exchange heat with another fluid (e.g., water). Specifically, for example, compressed air can be used to boil water by exchanging heat with water, which contributes to the effective use of generated energy. [Industrial Applicability]

[0065] The present invention is capable of compressing various fluids by adjusting the width of upward movement of the compression unit 2, installing a push-up unit 4, or adding compression units 2 and sliding units 3, and is therefore particularly suitable for use in offshore resource mining sites for natural gas and the like, and in offshore and coastal facilities that use high-pressure air. Therefore, it is believed that the "fluid compressor" of the present invention has great industrial applicability. [Explanation of symbols]
