Problems solved by technology

However, in the process of operation, the generator of the AWS device showed obvious shortcomings: the generator is too large and the cost is too high; the suction between the mover and the stator is large, which brings great problems to the support system of the bearing; at the same time, There are also issues with generator losses and cooling
Therefore, it is necessary to eliminate the energy loss and instability caused by the induced magnetic field in the LMMHD wave energy direct power generation system

Abstract

An electric generation unit driven directly by wave energy in near sea and with dual channels formed by a single tube and liquid metal as magnetic fluid is composed of a magnetic body with central hole, magnetic fluid electrodes, a U-shaped tube passing through said central hole of magnetic body to form a lower annular loop, two elastic containers, and a rigid container. Under the action of wave energy, said liquid metal flows in U-shaped tube to generate inductive E.M.F. It has high output voltage.

Description

technical field [0001] The invention relates to a liquid metal magnetic fluid wave energy direct power generation device, in particular to a single-tube double-channel wave energy liquid metal magnetic fluid power generation unit device. 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. So far, there are about 10 wave power generation systems with an output power exceeding 100kW, and the maximum installed capacity has reached 750kW. [0003] At present, the wave energy generation system generally adopts the combination of oscillating water column and air impeller, oscillating float type, pendulum type, raft type and ...
