There are various huge energy in the ocean, and the wave energy is one of the main energy of the ocean energy, and the purpose of relieving energy pressure and improving the environment can be achieved by developing and utilizing the wave energy. The commonly used wave energy generating devices include swing type, wave surface raft type and oscillating water column type, but all have the following problems, the mechanism is huge, the requirement for wave condition is high, the power generation is low, and most of the equipment is expensive and the maintenance cost is high.

[0033] In the generator unit, the polytetrafluoroethylene ball 8 is rubbed with the friction film, and the electrodes of the two are opposite.
