Description

technical field [0001] The invention belongs to the technical field of wind energy power generation and wave energy power generation, and in particular relates to an offshore wind energy-wave energy combined power generation device. Background technique [0002] Wind energy and wave energy on the ocean are renewable and clean energy in the ocean. Wave energy is a new type of renewable clean energy, and it is also a typical offshore energy resource. It has been valued by countries all over the world and has extremely high development potential. Wave energy is the most widely distributed renewable energy in the ocean. Compared with other offshore energy sources, wave energy is mainly converted into mechanical energy during the development process, which is less harmful to the environment. Wave energy has the advantages of wide distribution and high energy density, and is inexhaustible. However, how to make more effective use of wave energy to benefit mankind is currently the ...
