Problems solved by technology

The natural wind is erratic, which causes the brake device to be used very frequently. At present, the brake device of wind turbines mostly uses hydraulic caliper brakes. In order to increase the braking torque, a high-pressure hydraulic system is required, which has the disadvantages of high cost and high energy consumption, and is extremely inconvenient to maintain.

Abstract

A self-torque-takeoff brake device of a wind power unit is composed of a transmission shaft, a first gear, a gear shaft, a second gear, a fixing support, an electromagnetic clutch, a third gear, a motor, a fourth gear, a floating clamp, a screw shaft, a nut, a first friction plate, a second friction plate, a rotating speed sensor, a control unit and a brake pad. Kinetic energy of a wind power transmission system is fully utilized, braking is realized through a power takeoff mechanism, a movement conversion system and a control system, and an external power source is not needed. The self-torque-takeoff brake device has the advantages of compact and simple structure, high energy saving efficiency, convenience in mounting and high response speed.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a self-capturing torque braking device for a wind turbine. Background technique [0002] Wind power is a kind of clean energy, and its proportion in the power system is increasing day by day. Due to the randomness and intermittent nature of wind power, problems such as voltage fluctuations, frequency offsets, and harmonic pollution caused by wind power to the power system have become increasingly prominent. . [0003] The brake device of the wind turbine is an important part of the main drive system of the wind turbine and an important link to ensure the safe operation and parking of the wind turbine. The natural wind is erratic, which causes the brake device to be used very frequently. At present, the brake device of wind turbines mostly uses hydraulic caliper brakes. In order to increase the braking torque, a high-pressure hydraulic system is required, which has t...
