Description

technical field [0001] The invention relates to a self-power supply device for a drifting buoy complementary to wave energy and solar energy, and belongs to the field of comprehensive utilization of renewable energy. Background technique [0002] Drifting buoys are currently widely used marine hydrometeorological monitoring platforms. They are buoys that float on the sea surface or at a certain depth with ocean currents. Their position information is obtained by satellite or acoustic methods. . Drifting buoys are disposable, and their long-term continuous monitoring at sea cannot be recovered and replaced. Therefore, long-term continuous power supply of drifting buoys is one of the difficulties. With the development of science and technology, the currently available marine natural resource power generation technologies mainly include wind energy, solar energy, and wave energy. Designing a self-powered drifting buoy device has become a hot research direction. [0003] For e...
