Abstract

An automatic power take-off and bidirectional push type electronic mechanical brake device for a wind turbine generator comprises a brake disc, brake calipers, a first extrusion part, a second extrusion part, a fixing support, a motor component, a screw, an electromagnetic clutch, a first gear, a second gear, a transmission shaft, a brake shaft, a fixing flange, a first friction plate, a second friction plate, a speed sensor and a control unit. The automatic power take-off and bidirectional push type electronic mechanical brake device has the advantages that a power take-off mechanism and a motion conversion mechanism are used, the kinetic energy of the transmission shaft of the wind turbine generator is used as the power source, the bidirectional friction plates are allowed to apply brake pressure for braking at the same time, the extrusion parts are positioned through clamp grooves, the first extrusion part and the second extrusion part are mutually positioned through stepped faces, and great convenience in mounting and maintenance is achieved; the device is compact and simple in structure, energy-saving, efficient, convenient to mount, fast in response, and the like.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a self-powered and bidirectional push-type electro-mechanical 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 adopts hydraulic caliper brakes. The brake pressure is applied on one side, and then the fr...
