On-line flaw detection device of wind generating set

Abstract

An on-line flaw detection device of a wind generating set comprises an electromagnetic vertical climb robot, a circumferential movement and circumferential adjustment robot and a flaw detector, wherein the electromagnetic vertical climb robot is connected with the circumferential movement and circumferential adjustment robot and the circumferential movement and circumferential adjustment robot is connected with the flaw detector. The on-line flaw detection device provided by the invention adopts a surround type detection manner, and since the surface area of a wind power tower tube is extremely large and is of a circular terrace, the radius change amplitude is larger. A common detection means can hardly meet the detection requirements of high efficiency, quickness and full coverage, so the surround type detection manner is most suitable for the detection of the tower tube. In order to adapt to different tower tube sizes, a surround type detection device is modularized, so that the device can adapt to the tower tubes of different sizes by increasing and decreasing the number of modules. Through combination of a traditional detection technology and a moving machine technology, high-efficient and quick flaw detection on the tower tube is realized.

Description

technical field [0001] The invention is aimed at a device that solves the reliability, safety, immediacy and high efficiency of the tower detection of large and medium-sized wind power generating sets, and innovatively integrates the detection technology with the motion machinery technology and the remote control technology. But the main technical field still belongs to a type of detection flaw detection. Background technique [0002] At present, the maintenance and overhaul of large and medium-sized wind turbines are mainly divided into regular maintenance, special maintenance and regular maintenance. [0003] Routine maintenance is usually carried out with patrol inspections, including inspection, cleaning, adjustment, oil filling and troubleshooting of temporary faults. Special maintenance is carried out when major safety hazards are found in the unit or damage to main components occurs. This kind of maintenance technology is complicated, the workload is heavy, the cons...

AI Technical Summary

Problems solved by technology

Personnel climbing detection is mainly carried out through safety ropes or large-scale lifting equipment with hand-held flaw detectors. The detection is difficult and risky, and the life safety of engineers and technicians cannot be fully and efficiently guaranteed. In addition, the efficiency and accuracy of manual detection are difficult to guarantee. , and is greatly affected by the objective factors of the weather, it is even more difficult to realize the detection of wind turbines built on mountains, in the sea and in very complicated areas

The detection of small climbing robots can only achieve simple detection of a certain point or a certain area. Although it solves the problem of personnel safety, the efficiency is still very low. Minor damage cannot be dealt with immediately, and major damage cannot be accurately marked and identified. It is difficult to communicate with engineering Technicians realize online interaction and real-time communication

Limited by the environment and the level of engineering and technical personnel, it is difficult to guarantee the quality of flaw detection
