- the electrical energy produced by the generation of hydropower by discharge of the received fluid and the generation of potential energy by the lowering of the buoyancy body is applied to another buoyancy generator installed adjacently, and the buoyancy generator receiving the power is a fluid.
- the buoyancy of the buoyancy body 20 according to the acceptance of the electric energy will be produced.
- FIG. 9 is a block diagram of another embodiment in which a plurality of buoyancy generators according to the present invention are installed.
- a second buoyancy power generator 2 composed of a first buoyancy power generator 1 and a second buoyancy power generator 2 installed adjacent to each other and installed adjacent to the first buoyancy power generator 1 is provided. Is configured to jointly use the pump 52 and the storage tank 40.
- the fluid discharged from the body housing 10 of the first buoyancy power generator 1 is accommodated in the storage tank 40 and the body housing 10 of the second buoyancy power generator 2 by pumping the pump 52. Is supplied.
- the first buoyancy power generator 1 has a potential energy due to the falling of the buoyancy body and the hydro power generation by the discharge of the fluid, while the second buoyancy power generator 2 is the electrical energy due to the rise of the buoyancy body Produced.
- the fluid discharged from the body housing 10 of the second buoyancy generator 2 is received in the storage tank 40 and the body housing 10 of the first buoyancy generator 1 by pumping the pump 52. Is supplied.
- the second buoyancy power generator 2 is generated by the potential energy due to the falling of the buoyancy body and the discharge of fluid, while the first buoyancy power generator 1 is the electrical energy due to the rise of the buoyancy body Produced.
- the main body housing 10 to which the discharged fluid is supplied under the control of the controller 40 is selected so that the electrical energy generated by the discharge of the fluid and the electrical energy generated by the falling of the buoyant body are adjacent to each other.
- the fluid discharged from the power generator is configured to receive the electrical energy in the body housing 10 to which the electric energy is applied.
- Such a configuration has the advantage of reducing equipment costs by jointly using the pump 52 and the storage tank 40 used for pumping.
- the present invention has been made to solve the problems of the prior art, to provide a buoyancy power generation device that generates power by hydraulic, gravity and buoyancy.
