Description

  The present invention relates to a power generation system in which a generator is installed at a floating facility and power can be generated using natural energy.

  Conventionally, wind power generation and solar power generation have been developed as a power generation system using natural energy. In these cases, since they are greatly affected by the weather conditions, they are used in a complex manner.

Further, as a power generation system at sea, there is a wave power generation as disclosed in JP-A-11-159435. Again, this is highly dependent on weather conditions. Further, a marine nuclear power plant such as JP-A-11-038172 is also disclosed.

  At present, a stable power generation apparatus has not been established using natural energy. Conventional fossil fuels and nuclear power, which are conventional power generation methods, are faced with various problems such as plutonium disposal problems, CO2 generation, resource drumming such as global warming.

  In order to solve the above problems, in the present invention, an air storage tank, an air compression device for feeding compressed air into the tank, a generator, and a generator for driving the generator to the sea-floating facility. A water pressure guiding means for feeding seawater, the water pressure guiding means is connected to the generator of the above sea levitation facility, the water pressure guiding main pipe extending into the sea, and the compressed air stored therein. A compressed air induction pipe connected to an air storage tank and for sending compressed air into the underwater side opening of the hydraulic pressure induction main pipe. By sending compressed air into the underwater side opening of the seawater, the compressed air rises in the hydraulic pressure induction main pipe by buoyancy, and the compressed air that has become bubbles rises. Inflated, pushes up the seawater by the buoyancy and the expansion force to induce water pressure, it is an hydraulic induced power generating system according to the air buoyancy, characterized in that to drive the generator of offshore floating facility.

  The sea levitation facility may be any as long as it has a power generation system and can be a levitation base that can float on the sea. The air storage tank may be any tank as long as it can store compressed air, and may also be used as an air storage tank as buoyancy of a sea-floating facility. The generator may be any generator that is driven by water pressure.

  Further, the water pressure induction main pipe is a pipe for supplying water to the generator, and is a pipe extending toward the seabed in the sea, and the pipe length is preferably 10 m or more. Longer time is better, but it is better to set timely depending on the ability of the air compressor to supply air. The tube diameter is preferably 100 mm or more. The larger the tube diameter, the better, but the tube weight becomes heavier. Also, a plurality of the main pipes may be installed and merged at the upper part. The upper tube diameter may be changed. The material of the tube is preferably a lightweight material with high strength and good corrosion resistance. In addition to a rust-proof metal pipe, a resin pipe or the like may be used.

  The induction pipe supplies compressed air in the air storage tank to the tip of the hydraulic pressure induction main pipe, and is piped along the main pipe and opened in the tip of the main pipe. It is. Any pipe that has the strength to withstand the pressure of compressed air and that has excellent corrosion resistance may be used. For example, a corrosion-resistant metal pipe such as titanium or duralumin or a resin pipe may be used. The tube diameter is sufficient if compressed air can be supplied to the main pipe, and is preferably about 5 mm to 50 mm. Further, the diameter of the tube at the tip opening may be increased so that bubbles are enlarged. In addition, a bubble reservoir may be provided to enable stable bubble formation.

  Further, in the present invention, the air compressor described above generates compressed air by driving the floater with wave power, or generates compressed air by driving with wind power using a propeller and a crankshaft. An air compressor using wind power or an air compressor driven by the power of a solar cell is used.

  The above-described water pressure guiding means is a water pressure guiding main pipe having an inner pipe diameter of 100 mm and a tip depth of 10 m, a compressed air pressure of 10 atm, a pipe diameter of the guiding pipe of 10 mm, and a supply air amount of 1 liter per second. When intermittent supply is performed at intervals of 1 second, the amount of seawater discharged is about 5 to 20 liters per second on the sea, and sufficient induction pressure for driving the generator can be secured.

  By using the power generation system described above, a power generation system utilizing natural energy can be obtained that has a great effect in preventing environmental pollution.

  The present invention described above in detail has the following effects.

1) Electricity can be generated using natural energy without using nuclear power or fossil fuels.

2) By sending compressed air to the main pipe on the sea floor, water pressure is induced by the buoyancy of the air, and a power generation system using water pressure that is blown up on the water as increased energy can be realized.

3) The power source of the air compressor can also use natural energy, and an air compressor using wave power, wind power, and solar heat (solar cell) can be realized.

4) It is possible to provide a power generation system that can have a great effect in preventing environmental pollution such as disposal problems, CO2 generation, and global warming.

  The present invention has been engaged in dredging work such as sludge on the seabed for many years, and supplies compressed air to the suction port in sludge removal work in the deep sea where it is difficult to suck up only with a pump. As a result of discovering that the suction force of the pump can be supplemented by the buoyancy of the air, and further conducting extensive research, the water pressure can be induced by the buoyancy of the air, and the generator can be driven by the induced water pressure. We found it possible, developed a marine power generation system using only natural energy, and completed the present invention.

  Embodiments of the present invention will be described below with reference to the drawings. In the embodiment shown in this drawing, as shown in FIG. 1, a power generation base is installed in a floating facility, and the whole base is floated by a floater. An air storage tank 6 is used as the base part of the floating facility. The main device has the following configuration. An air compression device A that produces compressed air, a water pressure induction means that includes a water pressure induction main pipe 8 that serves as a flow path for air to be blown up and seawater, and a guide pipe 9 that sends air to the tip side of the water pressure induction main pipe 8 on the seabed. , C and a power generator B.

  FIG. 2 shows the air compressor A shown in FIG. 1, and this air compressor A uses wave power. The piston 2 in the cylinder interior 1 is moved up and down by the floater 4 by the height difference due to the wave period and the rise of the water level. When the piston (a) 2 moves down together with the floater 4, the air sucked from the intake hole 3 is compressed to a certain pressure by the rise of the piston (a) 2 together with the floater 4 and is sent into the air storage tank 6. . By repeating this motion, the compressed air is stored in the tank 6. At this time, a check valve 5 is attached to the joint between the intake hole 3 and the air storage tank 6 so that air does not escape. Since the tank 6 needs to be blown with stable compressed air, it needs to maintain a constant air pressure and an amount of air. Therefore, a pressure control valve 7 is attached between the pressure control chamber and the air storage tank 6.

  FIG. 3 shows a water pressure guiding means for pumping seawater to the power generator B and its power generator 10, and in the pipe on the opening side of the bottom of the water pressure guiding main pipe 8 connected to the power generator 10 on the sea, By sending compressed air from the air storage tank 6 through the induction pipe 9, the seawater in the main pipe 8 is sent together with the air to the generator 10 to generate electricity.

  When compressed air is sent into the air injection part 9a on the tip side of the water pressure induction main pipe 8, the compressed air becomes bubbles and rises in the main pipe 8 by buoyancy. As the bubble rises, the bubble expands, and while the air pipe and the seawater layer are alternately formed in the main pipe 8, the bubble continues to rise and pushes up the seawater by buoyancy.

  Here, when the water bubbles are deep, even if they are small, when they rise in a limited space called a pipe due to buoyancy, the bubbles expand with the rise, so that an air layer and a seawater layer are formed in the pipe. . As a result, the buoyancy of the air layer pushes up the seawater layer. If the bubbles remain small, only the bubbles will rise by pushing out the seawater, but when the bubbles of air compressed in a deep water depth rise, it will expand and become bubbles that are as large as the pipe diameter At that time, the seawater cannot be pushed out, an air layer is formed in the pipe, and the seawater on the upper part is pushed up.

  By alternately forming a plurality of air layers and sea water layers, a force for pushing up the sea water layers is generated by the buoyancy and expansion force of the air layers. By increasing the amount of air to be supplied, the rising speed of seawater increases, but the amount of water supplied decreases. It is preferable to adjust so as to form an air layer having a capacity slightly larger than the capacity of the seawater layer. Moreover, you may make it adjust the balance of an air layer and a seawater layer by supplying air intermittently at intervals.

  In this way, the water pressure is induced, seawater is sent to the generator, and power can be generated.

  FIG. 4 shows the air compressing device C shown in FIG. 1, and this air compressing device uses wind power. The variable pitch two-propeller 11 and the crankshaft 12 are connected by a rotation shaft. A ball bearing 13 is provided between the propeller 11 and the crankshaft 12. Therefore, when the propeller rotates, the piston (b) 15 moves up and down. Air is compressed by the vertical movement of the piston (b) 15 and fed into the air storage tank 6. Moreover, even if the wind direction changes, the piston 15 and the crankshaft 12 are connected by the universal joint 14 so that the apparatus does not have any defects, so that the wind direction can be changed.

  Moreover, in this drawing, the air compressing device uses a wave power and wind power, but a solar cell is installed, and the compressor is operated by the electric power to send compressed air to the air storage tank 6. Things can be used.

  In this way, the power can be combined into one by operating the air compressor using wave power, wind power, and solar heat (solar cell). By sending air to the guide pipe to the seabed, the water pressure is induced by the buoyancy of the air and blown up on the water as increased energy. The energy can be connected to a generator to generate electricity.

  Further, the amount of energy blown up on the water can be controlled by the length of the main pipe and the amount of air to be fed. Therefore, power can be increased.

  If adjustment becomes difficult by the above method, the power can be increased by connecting the power of several main pipes.

  However, when the amount of air pressure sent due to the weather is insufficient, a power compressor is installed as auxiliary power to compensate for the insufficient amount of air pressure. By doing so, the amount of air pressure can be kept constant.
