Abstract

The wave power plant is arranged on the sea surface. It has a frame with a central horizontal rotating rod (4) and floats (10) on either side of it. Rotating arms (5, 6, 7, 8, 9) connect the floats to the rotating rod. When the wave causes the float to move up, it creates torque in the rotating rod in the direction of the rod's rotation. When the float is moved down, the same occurs.
