Description

technical field [0001] The invention relates to a liquid metal magnetic fluid wave energy direct power generation device, in particular to a direct drive liquid metal magnetic fluid wave energy power generation device submerged at a certain depth below the sea surface. technical background [0002] Wave energy is a kind of energy that exists in the form of large force (several tons to tens of tons) and low speed (0.5-2m / s). It is the energy with the highest grade and the largest proportion in ocean energy. With the gradual reduction of mineral energy in the world and the increasing environmental pollution, wave energy is undoubtedly one of the preferred clean and renewable energy sources, and wave energy power generation is at the top of the development and utilization of marine renewable energy. [0003] Traditional wave power generation uses a high-speed, low-torque rotating generator. To couple it with low-speed, high-force wave motion, a series of mechanical devices for ...

AI Technical Summary

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

The power generation floating tube has high conversion efficiency, high power density, simple and compact structure, low cost, and good mobility, but the output characteristics change with the change of the wave, which has great randomness and instability, and floats on the sea surface. Poor wind and wave resistance
