Breakwater structure for wave power generation using piezoelectric materials

Abstract

The invention discloses a breakwater structure capable of achieving wave energy electricity generating by using piezoelectric materials. The breakwater structure comprises a breakwater main body and amovable baffle, wherein the breakwater main body is arranged in an inclined mode, a plurality of grooves are formed in the inclined face of the breakwater main body, and a plurality of piezoelectricvibrators are arranged on the inner walls of the grooves; the movable baffle is arranged corresponding to the inclined face of the breakwater main body and is located on the surface of the inclined face, a plurality of bulges are arranged on the movable baffle, the bulges and the grooves are arranged in a one-to-one correspondence mode, and the bulges extend towards the interiors of the grooves; and an elastic piece is arranged at the end of each bulge, and a plurality of shifting pieces corresponding to the piezoelectric vibrators are arranged on the outer surfaces of the bulges. According tothe breakwater structure, a piezoelectric electricity generating technology is adopted, wave kinetic energy is directly converted to electric energy, the energy conversion efficiency is improved, themovable baffle is utilized as a wave energy absorbing device to play a buffering role, and the wave upwelling height is reduced; and the sizes of the piezoelectric electricity generating vibrators are small, a space in a breakwater is effectively saved, and the land space use rate behind the breakwater is improved.

Description

technical field [0001] The invention relates to the field of wave energy power generation, in particular to a breakwater structure using piezoelectric materials for wave energy power generation. Background technique [0002] The total length of my country's coastline is 32,000 kilometers, including 18,000 kilometers of mainland coastline and 14,000 kilometers of island coastline. It is the country with the longest coastline in the world. With the development of overseas artificial islands, my country's coastline will continue to extend, with huge coastal wave energy develop potential. Some isolated islands away from the mainland are limited by power transmission distance and power generation methods, and the power consumption on the island is tight. On the other hand, the energy density of wave energy is 4-30 times that of wind energy. must do. [0003] At present, the breakwater-type wave energy power generation device is mainly divided into three categories. The first typ...
