Abstract

The invention relates to the technical field of wind engine stall protection, and discloses a wind engine stall protection device which comprises a shell. A power shaft is movably connected to the middle of the shell, a brake pad is fixedly connected to the outer side of the power shaft, a brake cavity is formed in the inner wall of the middle of the shell, and reset springs are fixedly connectedto the inner wall of the middle of the brake pad. Centrifugal blocks are fixedly connected to the outer sides of the reset springs, and dielectric plates are fixedly connected to the middle inner walls of the centrifugal blocks. According to the wind engine stall protection device, the power shaft drives the brake pad to rotate, the brake pad drives the centrifugal blocks to rotate, and then positive plates, negative plates and the dielectric plates are used in cooperation, so that the effect of controlling on-off of electromagnets is achieved, the dielectric plates in the middles of the centrifugal blocks move along with the centrifugal blocks, the relative area of the positive plates and the negative plates is changed, the voltage between every two pole plates rises, the working voltageof a piezoresistor is reached, and the electromagnets are electrified to generate magnetic force repelling magnetic blocks.

Description

technical field [0001] The invention relates to the technical field of wind power engine stall protection, in particular to a wind power engine stall protection device. Background technique [0002] Wind energy is a clean, safe and renewable green energy, which is inexhaustible and inexhaustible. It has gradually become a new energy source that is vigorously developed and utilized by countries all over the world. At present, wind energy is mainly used by placing the rotating blades on In the vast plains, the mechanical energy is transferred through the rotation of the blades for power generation, and the wind energy is converted into electrical energy. Most of the traditional wind turbines use a gearbox between the wind wheel and the generator to control the speed of the generator. [0003] Due to the changeable natural environment, severe thunderstorms and storms are often encountered. The blades of wind turbines rotate at a fast speed. To replace parts, construction perso...
