Abstract

FIELD: hydroelectric power engineering. SUBSTANCE: two rocking blades are installed on opposing vertical posts under water surface and piston pump is placed between them and hinged to blades. Pump is connected through compensator and piping to water-wheel generator. Working surfaces of wave-taking blades are made variable by means of hydraulic turbines. Variation in surf force causes displacement of movable plates of wave-taking blades along fixed central plates over guides under the action of hydraulic cylinders thereby increasing or decreasing working surfaces of blades which makes it possible to regulate power plant load. EFFECT: improved power take-off, simplified design of power plant. 3 cl, 6 dwg

The invention improves the power take-off and simplifies the design of the surf hydroelectric power station. Two swinging blades are mounted against each other on vertical supports below the water level, and a piston pump is located between them and is pivotally connected to the blades. The pump, with the help of a compensator and a pipeline, is connected to a hydraulic turbine with an electric generator. The working surfaces of the wave receiving blades are made variable using hydraulic cylinders 10. When the surf force is changed, the moving plates of the wave receiving blades 3 move along the central stationary plates along the guides under the action of the hydraulic cylinders, increasing or decreasing the working surfaces of the blades, which allows stabilizing the load of the surf hydroelectric power station.
