Swinging type wave energy fluid metal magnetohydrodynamic electricity generation float tube

Abstract

Disclosed is a wave energy swaying type liquid metal magnetic fluid power generation floating tube which is composed of a hook ring (1), a floating tube shell (2), storage containers (3-1) and (3-2), a power generation channel (4), a magnet (5), electrodes (6), a power output system (7) and liquid metal (8). The power generation floating tube floats on the sea and sways along with the wave surge. The liquid metal (8) moves back and forth in the power generation channel (4) along with the swaying of the floating tube shell (2), and interacts with the magnetic field generated by the magnet and generates induced electromotive force; then the electricity power is output through the plate electrodes (6) and the power output system. The wave energy swaying type liquid metal magnetic fluid power generation floating tube of the invention has the advantages of high conversion efficiency, large power density, compact and simple structure, low cost and good mobility; and is easy for commercial popularization.

Description

technical field [0001] The invention relates to a liquid metal magnetic fluid wave energy direct power generation floating tube, in particular to a swing type wave energy liquid metal magnetic fluid power generation floating tube. Background technique [0002] It has been the dream of mankind for hundreds of years to effectively utilize the huge ocean wave energy resource. 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] The traditional wave energy power generation system generally consists of three parts, namely wave collection system, intermediate conversion system and power generation system. The wav...

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

However, the device is vertically arranged in seawater near the sea surface, can only use the potential energy of waves, and has poor resistance to wind and wave impact
