PURPOSE: A power generation device using hydraulic power and buoyancy is provided to produce electric power with hydroelectric power generation using buoyancy energy by installing a buoyancy member, generating buoyancy energy by rising according to the water level of the upper stream and downstream of a dam of a hydraulic power plant. CONSTITUTION: A power generation device using hydraulic power and buoyancy comprises a hydroelectric power generation device and a buoyancy generation device. The hydroelectric power generation device comprises a dam, a water gate, and a water power generator. The buoyancy generation device comprises a water gate, a water power generator, and a buoyancy member(2), a piston(4), a cylinder(8), and a driving unit. The water gate is installed at the dam to open and close in order to discharge the water of the upper stream stored in the dam. The water power generator produces the electricity by rotating a turbine using the potential energy of the water discharged in the dam. The buoyancy member is installed at the water surface of the upper stream and the downstream of the dam. The piston is connected to the lower surface of the buoyancy member. A plurality of cylinders is fixed under water on the upper stream and the downstream. The driving unit generates the driving force from the motion of the piston. |
