Energy-saving wind generating set monitoring device

Abstract

The invention discloses a monitoring device for an energy-saving wind power generating set, which includes a wind deflector, a generator housing and a tail rudder. The engine housing is also provided with a vibration acceleration sensor, a vibration eddy current sensor, a photoelectric speed sensor, a metal particle detection sensor, Multi-channel pre-signal processing module, synchronous multi-channel analog-to-digital conversion module, signal processing transmission module and host computer, the vibration acceleration sensor and the photoelectric speed sensor are all set on the rotor, and the vibration eddy current sensor is set on the wind turbine of the wind turbine. On the blade main shaft, the signal output terminals of the vibration acceleration sensor, vibration eddy current sensor, photoelectric speed sensor and metal particle detection sensor are respectively connected to the signal input terminals of the multi-channel pre-signal processing module. Monitoring the status of the wind power generator avoids the defects of manual detection, ensures the normal operation of the wind power generator, and improves the utilization rate of the wind power generator.

Description

technical field [0001] The invention relates to the technical field of energy-saving wind power generation, in particular to an energy-saving wind power generation unit monitoring device. Background technique [0002] Wind turbines use wind power to generate electricity, which is a kind of green energy. They are generally installed in remote wind farms. The wind turbines are located in the cabin on the top of the tower, and the maintenance and repair of the turbines are relatively difficult. Affected by the harsh natural environment and complex generator sets and power electronic devices, wind turbine equipment is prone to failures, including gear bearing failures of gearboxes, bearing failures of generators, lubrication system failures, and main shaft impeller failures. Once the above faults occur, it will cause the unit to shut down, causing great losses, and the maintenance and repair of the unit is difficult and costly. For example, the Chinese patent "CN203532166U" incl...
