Wave power generation device based on magnetofluid resonance

Abstract

The invention discloses a wave power generation device based on magnetofluid resonance. The wave power generation device comprises a vibration unit and a power generation unit, wherein the vibration unit comprises a vertical rod and an air cylinder; one end of the vibration unit is connected with a floater; the other end of the vibration unit is connected with a piston; the air cylinder is used for containing the piston; the power generation unit comprises a plurality of power generation pipelines; the power generation pipelines comprise horizontal segments with rectangular cross sections; magnets are mounted on the external surfaces of opposite wall surfaces of the horizontal segments; and electrodes are mounted on another opposite wall surfaces of the horizontal segments respectively. The floater is immersed in seawater to make up-and-down motion along with a wave of the seawater, and then drives the piston to make reciprocating motion in the air cylinder to increase or reduce gas pressure in the air cylinder; change of the pressure allows liquid metal in the horizontal segments of the power generation pipelines communicated with the air cylinder to make reciprocating oscillation to cut magnetic induction lines generated by the magnets to generate electric energy; and then the electric energy is collected by the electrodes. The power generation device is used for converting mechanical energy contained by the wave into the electric energy, is high in energy conversion efficiency, and is suitable for the waves with various frequencies.

Description

technical field [0001] The invention belongs to the field of marine renewable energy utilization, and more specifically relates to a wave energy generating device based on magnetic fluid resonance. Background technique [0002] The energy contained in the waves of the ocean is huge. Like wind energy and solar energy, it is a green energy that exists in nature. It can be used continuously and can be used to generate electricity. During the "Ninth Five-Year Plan" period, with the support of the Ministry of Science and Technology's research plan, Guangzhou Energy Research Institute has developed a 100kW oscillating water column wave power station in Zhelang, Shanwei City, Guangdong Province, which can realize grid-connected operation. The 100kW pendulum wave power station developed by Tianjin National Institute of Ocean Technology was successfully operated in Qingdao in September 1999. my country plans to build a 1000kW shore-based wave power station in Shanghai, Hainan, and G...
