TIDAL POWER STATION Russian patent published in 1994 - IPC

FIELD: hydraulic power engineering. SUBSTANCE: blade 3 and piston pump 4 are mounted on vertical piles 1, 2 under the water level and are made rolling around vertical axes by an articulated joint of the rod of pump 4 and blade 3. Piston pump 4 is connected to hydraulic turbine 5 by compensator 6, the turbine is mounted on a platform over the water level. The working surface of blade 3 is varied by a power hydraulic cylinder. When the power of the tide varies the movable plate of blade 3 moves along a stationary plate on guides by a power hydraulic cylinder increasing or decreasing the working surface of blade 3. EFFECT: improved stability of power station load. 2 cl, 4 dwg
