Embodiment 1

[0018] figure 1 Cutaway for the Wave Duck. 1 is the outer casing of the wave pendulum, and 2 is the swing shaft. With the ups and downs of the ocean waves, the wave duck type wave pendulum swings up and down to drive the swing shaft to swing, and the energy of ocean waves converges into the swing kinetic energy on the swing shaft. The shape of the wave pendulum is designed to absorb wave energy to the greatest extent: the tail is a garden column with a radius of R, the back is a straight line, the duck toe is arc-shaped, and the duck head is a garden head. The waves coming from the left make the wave pendulum swing, and the tail of the wave pendulum is made into a cylinder, so that there are no waves on the sea surface on the right. 3 is the sealed space inside the wave pendulum, which can inject seawater or discharge sea water to control the wave pendulum to have a suitable draft. Changing the width of the wave pendulum of the ocean wave duck can change the energy value of ...

Embodiment 2

[0020] figure 2 It is a cross-sectional schematic diagram of the ocean wave canard superconducting magnetic fluid power generation system. Wherein 4 is a rotating shaft, 5 is a transmission rod, 6 is a hydraulic pump, 7 is a liquid metal (such as mercury), 8 is a magnet (superconducting magnet), 9 is a cooling device, and 10 is a straight tube power generation channel. With the ups and downs of the ocean waves, the wave duck 1 swings up and down to drive the swing shaft 2 to swing, and the kinetic energy of the swing drives the piston of the upper and lower hydraulic pump 6 through the up and down rotation shaft 4 and the up and down transmission rod 5. figure 2 Moving back and forth in the direction of the arrow drives the liquid metal 7 to move back and forth in the straight tube power generation channel 10, cutting the magnetic field generated by the magnet 8 to generate induced electromotive force power generation. The cooling device 9 is used to cool the temperature ri...

Abstract

The invention relates to an ocean wave canard superconductive magnetic fluid power generation system and an ocean wave canard superconductive magnetic fluid power generation method, wherein ocean wave energy is converted into swinging kinetic energy which is directly converted into electrical energy by a superconductive magnetic fluid power generation device; the width of ocean wave canard wave pendulums are changed, and the energy value of ocean wave energy accumulated by the system is changed; the shape of the wave pendulums is as follows: tails of the wave pendulums are cylinders the radius of which is R, backsides of the wave pendulums are straight lines, canard toes are cambered, and canard heads are round; upper parts and lower parts of the wave pendulums are connected with rotating shafts respectively; the rotating shafts are connected with transmission rods which are connected with and drive a piston of a hydraulic pump; liquid metals are arranged inside the hydraulic pump which is connected with the superconductive magnetic fluid power generation device; and a cooling apparatus is connected with the superconductive magnetic fluid power generation device. The ocean wave canard superconductive magnetic fluid power generation system drives the liquid metals to flow to and fro in a straight-pipe power generation channel of the superconductive magnetic fluid power generation device, so as to generate induced electromotive force and then generate electricity. The system is simple and reliable and has small maintenance. Moreover, the kinetic characteristics of the generators are tallied with motion of the waves, so that the conversion efficiency of the system is greatly improved.

Description

technical field [0001] The invention relates to an ocean wave canard superconducting magnetic fluid power generation system and a power generation method using ocean wave energy for power generation, and belongs to the field of hydropower generation using ocean wave renewable energy. Background technique [0002] With the reduction of non-renewable energy stocks such as oil and coal and the intensification of the greenhouse effect caused by environmental pollution, people began to seek new energy sources. As a renewable energy, ocean wave energy has been paid more and more attention by people. It has been the dream of mankind for hundreds of years to effectively utilize the huge ocean wave energy resource. As a clean and renewable energy, wave energy has increasingly attracted global attention, and wave energy power generation technology is developing rapidly. So far, there are about 10 wave power generation systems with an output power exceeding 100kW, and the maximum ins...
