Float suspended liquid metal magnetic fluid wave energy direct generating device

Abstract

A float suspended liquid metal magnetic fluid wave energy direct generating device is composed of a float retractable wave-capturing device, a reciprocating compression device, a coupling device, a suspended liquid metal magnetic fluid generator and a mooring gear. The float retractable wave-capturing device integrates the advantages of float type, raft type and retractable slopeway type wave-capturing device, can absorb wave energy of vertical and horizontal direction and can improve absorption efficiency of wave energy. The suspended liquid metal magnetic fluid generating device can be suspended on the sea vertically and is easy for installation and maintenance.

Description

Technical field [0001] The invention relates to a liquid metal magnetic fluid wave energy direct power generation device, in particular to a wave energy direct power generation device adopting a floating and retractable wave catching device and a suspended liquid metal magnetic fluid generator. technical background [0002] The effective use of huge ocean wave energy resources has been the dream of mankind for hundreds of years. With the intensification of the greenhouse effect caused by the fossil energy crisis and environmental pollution, wave energy, as a clean and renewable energy source, has increasingly attracted global attention, and wave energy power generation technology has developed rapidly. [0003] The wave capture system and the generator are two essential parts of the wave energy power generation system, and the degree of coupling between the wave capture system and the generator determines the existence of the intermediate conversion system. The wave capture syste...

Problems solved by technology

[0005] It can be seen that the wave capture systems commonly used at present, such as the float type, shrinking ramp type and raft type, mainly use a certain energy or movement of a certain direction of the wave, and the wave energy capture efficiency is not high, such as the wave energy absorption efficiency of the float type. Generally around 50%

Chinese patent 200610144400.5 and U.S. patent 5136173 disclose the MHD wave energy direct power generation system. The MHD generator is submerged below the sea surface and has good wind and wave resistance, but it is not easy to maintain and install.
