A semi-active ground effect wing hydroelectric power generation method and device

Abstract

The invention can be used in the field of seawater power generation. The present invention relates to a semi-active ground effect wing water current energy generation method and device, which solves the technical problems of existing devices such as dead spots, low transmission efficiency, difficult coupling of multiple hydrofoil movements, and no consideration of ground effect. There are generators, hydrofoils, and a flat slide rail mechanism, a hydrofoil pitching motion control mechanism, a hydrofoil heave motion control mechanism and a gear shaft; hydrofoils, a hydrofoil pitching motion control mechanism, and a hydrofoil heave motion control mechanism Both are two sets; the flat slide rail mechanism is equipped with an optical axis and a connecting plate, and the connecting plate is set on the optical axis; the hydrofoil pitching motion control mechanism is equipped with a stepping motor and a control device; A plate, a rack and a gear, the gear meshes with the rack, and the rack is arranged on the connecting plate; the power generation device is provided with a rack, a gear, a pinion shaft and a generator. The invention has high transmission efficiency and can effectively utilize the ground effect to realize high-efficiency energy harvesting.

Description

technical field [0001] The present invention relates to a power generation method and device, in particular to a semi-active ground effect wing water current energy power generation method and device. Background technique [0002] my country has a long coastline and abundant water current energy reserves, but it is less developed and utilized at present, so there is a huge development potential for water current energy power generation. Through the energy conversion device, the kinetic energy contained in the ocean current energy can be converted into electrical energy for utilization. There are currently three main types of water flow power generation devices, namely horizontal axis type, vertical axis type and oscillating hydrofoil type; among them, the horizontal axis type and vertical axis type are widely used, but their design requirements are high, and the water flow can be along the The unbalanced vertical distribution of water depth also reduces the conversion effic...
