The end of the main shaft is provided with a flywheel 7 which balances the rotating speed.

Because the utility model adopts a platform that can float on the water surface, a plurality of brackets are arranged on both sides of the platform to connect the floats, and the end of a main shaft in the middle of the platform is connected to the generator. When multiple floats move up and down in irregular sea waves, the thrust is increased through the leverage of the bracket, and the rocker arm on the main shaft is pushed back and forth by the push rod to drive the main shaft to rotate, so that the main shaft obtains power continuously, and the potential energy output through the main shaft enables power generation The machine rotates to generate electricity. Therefore, the utility model is simple in design, convenient in maintenance, large in energy acquisition, suitable for various sea areas, convenient in movement and strong in practicability.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

The utility model includes a platform for a power generation device composed of a generator 1, a transmission 4, and a shaft coupling 2, 5. The two ends of the platform are connected with buoys 12 that can float on the water surface, and a main shaft 11 is arranged on the central axis of the platform 13. Regular hexagon; platform 13 is provided with a plurality of brackets 8, brackets 8 are flexibly connected with platform 13, one end of bracket 8 is connected with float 3 that moves up and down with the water body, and the other end is a connecting rod rocker device for transmitting power; connecting rod 17 is connected Rocking arm 9 and support arm 8; Rocking arm big head 18 is sleeved on the main shaft 11 and promotes main shaft 11 to rotate, drives generator to generate electricity, and rocking arm small head 19 is connected with connecting rod 17, and rocking arm big head 18 is provided with directional wheel 20.
