Ocean buoy utilizing solar energy, wind energy and ocean current energy for complementary power generation and energy supply and method

Abstract

The invention provides an ocean buoy utilizing solar energy, wind energy and ocean current energy for complementary power generation and energy supply and a method. The ocean buoy comprises an overwater platform, an underwater platform, a connecting piece, a wind turbine, a solar panel and a water-turbine generator set, the overwater platform and the underwater platform are connected through the connecting piece, the wind turbine and the solar panel are installed on the overwater platform, the water-turbine generator set is located in the underwater platform, the underwater platform floats in water to support the overwater platform in the upper portion of the water surface, and electric energy generated by the wind turbine, the solar panel and the water-turbine generator set is conveyed to a storage battery in the storage battery cabin to be stored or directly conveyed to various observation devices carried by the ocean buoy. The buoy overcomes the problems of easy observation interruption, unstable structure and easy damage caused by unstable power supply of the original buoy, and has the characteristics of simple structure, formation of complementary power generation, uninterrupted power supply, improvement of long-term stable observation performance of observation equipment, high structural strength, good stability and difficulty in damage.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and relates to a marine buoy and a method for generating and supplying energy by using solar energy, wind energy and ocean current energy to complement each other. Background technique [0002] Ocean buoy is a widely used marine hydrometeorological observation platform, which is placed on the sea surface and connected to the seabed through an anchor chain system. Various observation equipment can be carried on the buoy to measure various meteorological elements (such as wind speed, wave parameters, etc.) at sea. Because ocean buoys need to be placed on the sea for a long time, especially for ocean buoys placed in deep seas, the deployment period can reach several years, and the maintenance cost is high. important design considerations. At present, the marine buoy device that uses various renewable energy sources such as solar energy and wind energy in the surrounding environment of t...

Problems solved by technology

[0003] Chinese patent CN211930540U (Shi Xuetao, etc.) proposes a solar power supply device for marine buoys. The power supply device has self-cleaning function and is easy to install. Observation needs

[0004] Chinese patent CN110329436A (Lu Hai, etc.) proposes a buoy powered by wind and solar power, the buoy is equipped with batteries to store the generated power, which improves the flexibility and stability of the buoy energy supply system to a certain extent, however, wind power and Solar power generation is intermittent. If wind and solar power are not sufficient for a long time, or some equipment is damaged, there may still be some problems with the power supply of the buoy.

At present, Chinese patents CN205618293U (Wang Peng, etc.) and CN107401475A (Guan Saihu, etc.) have respectively proposed devices for generating electricity using ocean currents, but the above two patents are not designed for buoys, and their structural forms cannot be applied to ocean buoys
