Ground effect hydrofoil tidal current energy power generation device

Abstract

The invention discloses a ground effect hydrofoil tidal current energy power generation device, belongs to the field of tidal current energy power generation and ocean engineering equipment, and solves the technical problem of low generated power and multi-hydrofoil motion coupling of an oscillating hydrofoil power generation device in the prior art. The ground effect is utilized to improve the hydrodynamic performance of double-hydrofoil swinging, so that the power generation efficiency of the tidal current energy power generation device is improved. The power generation device comprises a four-bar mechanism, a crank connecting rod and a rack and pinion mechanism, and the four-bar mechanism is driven to run through up-and-down heaving motion of hydrofoils so as to drive a generator to generate power; and meanwhile, the four-bar mechanism can drive the crank connecting rod and the rack and pinion mechanism to move, and then a transmission wheel drives the hydrofoils to do periodic pitching motion, so that self-coupling of heaving motion and the pitching motion of the hydrofoils is guaranteed. According to the ground effect hydrofoil tidal current energy power generation device, self-coupling of heaving motion and pitching motion of the hydrofoils is realized, and continuous energy output of the device is ensured; and by utilizing the ground effect between the hydrofoils, the power generation efficiency of the oscillating hydrofoil tidal current energy power generation device is improved, and the power generation cost is reduced.

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
