A ground effect wing tidal current energy generating device

Abstract

A ground-effect wing tidal current energy generating device belongs to the field of tidal current energy generating and marine engineering equipment. The invention solves the technical problems of low power generation and multi-hydrofoil motion coupling of the oscillating hydrofoil generating device in the prior art. The ground effect is used to increase the hydrodynamic performance of the swinging wings, thereby improving the power generation efficiency of the tidal current power generation device. The power generation device includes a four-bar mechanism, a crank connecting rod and a rack and pinion mechanism. The up and down movement of the hydrofoil drives the four-bar mechanism to operate, thereby driving the generator to generate electricity; at the same time, the four-bar mechanism can drive the crank connecting rod and the rack and pinion. The structure moves, and then drives the hydrofoil to do periodic pitching motion through the transmission wheel, which ensures the self-coupling of the hydrofoil heave motion and the pitching motion. The invention realizes the self-coupling of the heave and pitch motions of the hydrofoils, ensures the continuous energy output of the device; utilizes the ground effect between the hydrofoils, improves the power generation efficiency of the oscillating hydrofoil type tidal current energy generating device, and reduces the power generation cost.

Description

technical field [0001] The invention relates to a power generation device, in particular to a ground effect wing tidal current energy power generation device, which belongs to the fields of tidal current power generation and ocean engineering equipment. Background technique [0002] Tidal current energy is one of the important energy sources in ocean energy, which can provide people with inexhaustible and inexhaustible energy. As people's requirements for a better environment become more and more urgent, the use of fossil energy is gradually subject to more and more restrictions. Clean energy will become the direction of future development. As an important clean energy, tidal current energy has obvious advantages such as large reserves, easy prediction, and simple acquisition. In addition, my country has a long coastline and abundant tidal current energy reserves. At present, there is very little development and utilization of tidal current energy, and it has huge developme...

Problems solved by technology

[0004] However, in the prior art, the hydrofoil tidal current energy generation device has low power generation efficiency and high power generation cost, making it difficult to realize large-scale market application. At present, people only increase the total power generation power by increasing the number of hydrofoils, but a single hydrofoil The power generation efficiency of the wing has not improved
