Abstract

The invention relates to a floating, fishlike and raft-type liquid-metal magnetohydrodynamic wave energy direct power generating device which mainly comprises a front float, a rear float, a hinge, a liquid-metal magnetohydrodynamic (LMMHD) generator, a mooring system, and the like. The power generating device has a floating structure and can be arranged at different sea areas according to requirements; an adopted fishlike raft-type wave energy acquisition device can absorb the wave energy better and simultaneously has stronger storm resisting capacity; and the power generating device adopts a liquid-metal magnetohydrodynamic direct power generating technology, has less intermediate conversion links and improves the whole conversion efficiency.

Description

technical field [0001] The invention relates to a liquid metal magnetic fluid wave energy direct power generation device, in particular to a power generation device using a fish-shaped or raft type wave energy capture device and a liquid metal magnetic fluid generator. technical background [0002] It has been the dream of mankind for hundreds of years to effectively utilize the huge ocean wave energy resources. With the aggravation of the greenhouse effect caused by the fossil energy crisis and environmental pollution, wave energy, as a clean and renewable energy, has increasingly attracted global attention, and wave energy power generation technology has developed rapidly. [0003] The wave energy capture system and the generator are two essential parts of the wave energy generation system, and the coupling degree between the wave energy capture system and the generator determines the overall efficiency of the wave energy generation system. The wave energy capture system,...
