Problems solved by technology

However, wind turbines based on the above working principles need to rely on gearboxes, resulting in very complex internal structures of wind turbines; or the use of permanent magnet direct drive generators with full-power inverters is costly
At the same time, the weight of existing wind turbines is relatively heavy, which increases the overall load requirements and costs of wind turbines

Abstract

The invention provides a wind power generation dual-drive transmission device. The wind power generation dual-drive transmission device comprises a power input mechanism and a transmission mechanism,and the power input mechanism drives the transmission mechanism to drive a power generator to work. Through cooperation of engagement and disengagement of a main disc and a movable tackle as well as engagement and disengagement of a sleeve shaft and a transmission gear, continuous and stable output of power is achieved, high power generation efficiency is achieved, and good environment benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a dual-drive transmission device for wind power generation. Background technique [0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Because wind energy is a kind of clean energy, using wind power to generate electricity is very environmentally friendly, and the generated electric energy is huge, so more and more countries pay more attention to wind power generation. At present, wind power mainly relies on wind power generators. Among them, the working principle of wind power generators is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the gearbox to prompt the generator to generate electricity or use huge permanent magnets without increasing the speed. Direct-drive generators paired with expensive full-power inverters generate electricity. However, the wi...
