Description

Wind driven generator tower body in-situ detection climbing robot
Technical Field
The utility model belongs to the technical field of climbing robots, and particularly relates to a wind driven generator tower body in-situ detection climbing robot.
Background
Under the large background of a double-carbon strategic target, wind energy is taken as a clean and renewable green resource, and plays an important role in reducing carbon emission, relieving greenhouse effect and promoting healthy and sustainable development of the environment, economy and society. With the rapid development of the wind power industry, the core requirements for wind power generators are higher power generation efficiency and less maintenance costs. At present, the number of wind driven generators in China is huge and the wind driven generators are in service for many years, and whether the fans can exert the optimal performance in the operating period is one of key factors for measuring the power generation efficiency. Therefore, operation and maintenance in the life cycle of the in-service wind turbine will be a great challenge.
The core components of the wind driven generator comprise blades, a tower, a generator, a gear box, a bearing, a hub and the like. In wind turbine structures, the tower acts to carry the loads of critical components in the supporting nacelle. The tower drum is of a hollow cylindrical structure with variable pitch diameter and variable thickness, and is generally of a three-section structure, namely a lower tower drum section, a middle tower drum section and an upper tower drum section, wherein the drum sections are connected through flanges and bolts. Once the tower barrel has structural failure, the whole wind driven generator may collapse, so that irreversible loss is caused.
The whole height of the tower body of the modern megawatt fan is generally more than 80m, the common tower body is 120m, the height is in a trend of increasing continuously, but the high tower body also has the unavoidable defect, the static strength of the structure is lower, and the deformation amount after loading is larger. Although the fan tower body is subjected to strict quality detection before delivery, some natural structural defects such as fine pores, fine cracks and the like still exist below the surface of the tower body. If the fatigue cracks can not be detected in time for corresponding overhaul, the wind turbine can cause a tower falling accident, and the life and property safety of people can be directly endangered. In addition, the working environment of the wind driven generator is relatively poor, the normal operation of the wind driven generator is always threatened by wind sand abrasion, seawater moisture corrosion and the like, the wind driven generator is easily influenced by working load and external environment in the power generation process of the wind driven generator, and faults occur, particularly the wind driven generator tower body. Under the action of such complex load, the tower body is easy to generate fatigue cracks, the fatigue cracks are easy to continue to expand and generate the instability of the tower body, once the instability phenomenon of the tower body occurs, the whole tower barrel is collapsed or is partially broken, and the whole fan is damaged. The tower body is easy to generate the conditions of crack, rust surface and the like due to the problems in the manufacturing, assembling and other processes of the tower body and the fatigue of the tower body after long-time use, the serious accident of the collapse of the tower body can be caused by not timely implementing corresponding maintenance measures, the irrecoverable economic loss and even the safety accident are caused once the fan tower body breaks down, and the later maintenance cost of the power generation equipment is very expensive.
At present, wind power enterprises mainly detect the tower body of the wind driven generator through manual detection and unmanned aerial vehicle detection, but the two conventional detection modes have obvious defects. Firstly, manual detection is that a detector works under the high altitude, the environment is severe, the dangerous degree is extremely high, safety accidents are easy to occur, and life threat is caused to the detector. The early fatigue crack in the tower body can not be detected by unmanned aerial vehicle detection, so that the early fatigue crack can be quickly expanded under a huge and complex moment after the day, the tower falling accident is caused, and huge economic loss is caused.
Therefore, the utility model provides a wind driven generator tower body in-situ detection climbing robot, which aims to reduce the risk of manual high-altitude operation, lower the operation and maintenance cost of a fan, discover early cracks in a tower body material, take corresponding remedial measures, prolong the service life of the fan and avoid the occurrence of a fan tower reversing accident.
