FIELD: wave power plants. SUBSTANCE: invention relates to a wave power plant using a reverse flow of water flows. The power plant contains an impeller in the form of a rotor 5 connected to a generator 4, a support fixed in the ground. The power plant is equipped with a second rotor 6 having a common axis with the first rotor 5, a platform 3 is placed on the support with a generator 4, front and rear pairs of wave-receiving shields 8 and 9 on their swivel supports with locks for the angles of their turn, located at an angle to the direction of movement of the direct and reverse flow of water. Rotors 5 and 6 are placed in a vertical position. Rotor 5 is positioned above still water to receive direct flow from wave action. The rotor 6 is placed under water to receive the reverse flow of water from damped waves. EFFECT: invention is aimed at improving the efficiency of the power plant and creating a simple design. 2 cl, 2 dwg.
