Due to the inertia effect, when the sea surface waves fluctuate, the device cannot synchronously move, and at the moment, the seawater drives the blades of the second water turbine to rotate through the guide cover to drive the third generator to generate electricity. The invention integrates three power generation modes, particularly can extract the energy generated by the relative motion of the device and the sea surface waves in the vertical direction, and improves the total power generation amount and the power generation efficiency of the whole device.
