Wind turbine generator overhead rail type cabin inspection system

Abstract

The invention relates to a wind turbine generator overhead rail type cabin inspection system which comprises an overhead rail arranged in a wind turbine generator cabin. The overhead rail is connectedwith a suspension arm. The suspension arm is driven by an electric device, can move along the overhead rail, and achieves telescopic and rotary motion in the vertical direction. The suspension arm isconnected with a camera holder, and the camera holder is fixedly provided with a bispectrum high-definition camera and an infrared temperature measurement camera. The inspection system further comprises a sound pressure sensor, a smoke sensor and an acceleration sensor which are arranged in the wind turbine generator cabin. The inspection system further comprises a signal acquisition instrument,a wind turbine generator industrial personal computer and a booster station industrial personal computer. According to the system, the functions of video monitoring, fire alarm, vibration monitoring,infrared temperature measurement and the like are integrated, integrated monitoring is realized, fan cabin equipment inspection manual operation can be replaced, the automation level of a wind power plant is improved, the number of wind power plant attendants is reduced, and the reliability of a wind turbine generator is ensured.

Description

Technical field[0001]The invention belongs to the technical field of wind power, and particularly relates to a hanging rail nacelle inspection system of a wind turbine.Background technique[0002]Wind power generation is currently an important part of my country's power generation field. As the core of wind power generation, wind turbines are one of the important daily tasks of wind power plants. The patrol inspection of engine room equipment requires operators to climb to the upper part of the wind turbine tower to enter the engine room for inspection. The safety of operation has the disadvantages of high labor intensity, low work efficiency, scattered inspection quality, and single method. The manual inspection data cannot be accurately and timely accessed MIS. Moreover, with the promotion of the unattended mode, the inspection workload is increasing, and the inspection arrival rate and timeliness cannot be guaranteed. In addition, under high altitude, lack of oxygen, cold and other...

Problems solved by technology

[0004] Generally, the site selection of wind farms is relatively remote and the geographical environment is relatively harsh. If each wind farm needs to be equipped with a certain number of maintenance personnel for daily inspection and maintenance, the demand for personnel is large and the cost is high; the video surveillance of traditional wind turbines and "Passive monitoring" is mainly "passive monitoring", which requires the on-duty personnel to monitor at all times. Most of the time it is only suitable for video review of case traceability. Vibration monitoring systems and other systems mostly operate independently, and it is difficult to achieve multi-system intelligent association and application integration. With the introduction of technical specifications, system integration has become inevitable; there are many large parts in the engine room, and the main engine manufacturers often use compact components to reduce the weight of the engine room. Due to the limited space in the engine room and the limited inspection route of the crawler-type inspection robot, it is impossible to realize the automatic inspection of the entire range of the engine room.
