Pressure reduction power generation device suitable for floating breakwater

Abstract

The invention discloses a pressure reduction power generation device suitable for a floating breakwater. The device comprises an outer frame, a pressure reduction mechanism, an electric energy conversion device and an electric energy storage device, wherein one end of the outer frame is deeply arranged in the floating breakwater, and the other end is exposed out of the floating breakwater; the pressure reduction mechanism is arranged at one end, exposed out of the floating breakwater, of the outer frame for converting wave energy to kinetic energy; the electric energy conversion device and theelectric energy storage device are arranged at the end, extending into the floating breakwater, of the outer frame; the electric energy conversion device is connected with the pressure reduction mechanism and converts kinetic energy of the pressure reduction mechanism into electric energy to be stored in the electric energy storage device. Slamming of waves on the breakwater is ingeniously utilized; wave slamming force is converted into electric energy, damage of waves to the breakwater structure is reduced, the safety of the breakwater is improved, the service cycle of the breakwater is prolonged, meanwhile, an electric energy source is provided for the wave absorbing and traveling dual-purpose floating breakwater and nearby islands, and the device has the advantages of being free of pollution, easy to assemble, capable of being produced in batches and the like.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and in particular relates to a decompression generating device suitable for floating breakwaters. Background technique [0002] The world has a vast coastline and many islands. Most of the islands are far away from the land. It is too expensive to rely on the mainland to lay submarine cables to transmit electricity. Relying on its own resources and some floating structures for power generation can most effectively solve the problem of electricity consumption. question. [0003] Fluid and structure relatively move and interact in a short period of time to produce a slamming phenomenon, and at the same time produce a shock load with a destructive force. When slamming, the impact of waves on the structure may cause strength damage. As a marine engineering structure for wave dissipation and wave prevention, floating breakwaters are more frequently slammed. In this case, it is not importan...

AI Technical Summary

Problems solved by technology

[0006] Scholars at home and abroad have done a lot of research on the hydrodynamic performance of floating breakwaters and their wave-absorbing effects. At the same time, research on the piezoelectric effect has become more and more in-depth, but the combination of piezoelectric effects and floating breakwaters has rarely been studied.
