Abstract

The invention relates to wave vibration piezoelectric power generation and solar energy combined power generating method and system. A solar-cell panel is used for converting solar energy into electric energy, and a piezoelectric element arranged on a cantilever slab is used for adsorbing the vibrating mechanical energy of waves; and when a power generating box is vibrated along with the waves, the cantilever slab is bent and elastically deformed so that the piezoelectric element adhered to the surface of the cantilever slab generates electric energy. The invention can effectively convert the wave vibration mechanical energy and solar energy into the electric energy and provides green power generating system and method. Meanwhile, the piezoelectric element of the invention is arranged in a power generating box shell, can not be impacted or damaged and has reliable work and high stability. In addition, the power generating system of the invention has the advantages of simple structure and low cost; and because solar energy and wave vibration can be obtained anywhere at broad lake or sea, and the bending deformation amount of a piezoelectric material, which is caused by vibrating, is larger, the invention has large power generating amount, wide application range and general applicability.

Description

Technical field [0001] The present invention relates to a power generation method and a power generation system thereof, in particular to a wave vibration piezoelectric power generation and solar combined power generation method and a power generation system thereof. Background technique [0002] With the development of science and technology and the acceleration of the modernization process, human demand for energy is increasing day by day, causing the primary energy consumption to rise sharply, and it will be exhausted in the near future. Therefore, people have set their sights on the largest energy storage on the planet-the sun and the ocean. Solar energy and ocean energy are clean energy sources that do not pollute the environment, and they are all renewable energy sources that are inexhaustible and inexhaustible. The use of solar energy and wave power generation can provide electricity for remote islands and offshore facilities. In addition, the power provided by solar energ...
