Abstract

The invention discloses a metal fluid wave power generation device, which solves the disadvantages of low conversion efficiency and low reliability for the existing wave energy conversion equipment. The main points of the technical scheme are that, the device comprises a cylinder, a piston rod and a piston, a floater fixedly installed to the upper end of the piston rod, and a heavy object fixedly connected to the lower end of the piston rod; a flow channel for pushing the piston to do reciprocating motions by the piston rod and pipe channels for communicating both ends of the flow channel so as to form a loop for flowing liquid metal are arranged in the cylinder; the pipe channels are arranged on both sides of the flow channel, a magnetic fluid power generation channel is arranged in the pipe channel, and the Tesla valves are installed in the forward direction along same clockwise direction of the pipe channel. The metal fluid wave power generation device of the present invention is compact and simple in structure and high in reliability, and it can efficiently convert wave energy into electric energy.
