Comprehensive safety detection system and method for wind generating set

Abstract

The invention discloses a comprehensive safety detection system and method for a wind generating set. The system employs the comprehensive detection of the combination of a digital image related technology and air coupling ultrasonic detection, and employs a flight device to carry detection equipment. Surface damage detection is carried out on the wind generating set through a shooting device, internal damage detection is carried out on the wind generating set through the air coupling ultrasonic detection device, all-directional damage detection of the wind generating set is achieved, damage images are visualized, positioning is easy and convenient, and therefore, the safety detection of the whole life cycle of manufacturing, installation and operation of the wind generating set can be realized, and the detection from the parts of the wind generating set to the whole machine is realized. According to the invention, the flight device is adopted to carry the detection equipment, the whole machine measurement process is convenient and safe, unnecessary climbing operation of workers is reduced, meanwhile, non-stop detection can be realized when fixed parts of the wind generating set such as a tower are detected, and the economical efficiency of the wind generating set is ensured.

Description

technical field [0001] The invention relates to the technical field of detection of wind power generators, in particular to a comprehensive safety detection system and method for wind power generators. Background technique [0002] A wind turbine is a mechanical device that converts the kinetic energy of the wind into mechanical energy through a wind rotor, and the mechanical energy drives the generator to generate mechanical equipment. It is usually composed of a wind rotor, a transmission, a tower and ancillary components. An important component whose function is to convert wind energy into mechanical energy through blades. During the service process of the blade in the wind turbine, on the one hand, the blade needs to bear the mechanical stress caused by aerodynamic load, and on the other hand, it will be damaged by ice coating, sand erosion, rain erosion and lightning strike in the natural environment, which makes the material and structure of the blade The damage is ma...

Problems solved by technology

During the service process of the blade in the wind turbine, on the one hand, the blade needs to bear the mechanical stress caused by aerodynamic load, and on the other hand, it will be damaged by ice coating, sand erosion, rain erosion and lightning strike in the natural environment, which makes the material and structure of the blade The damage is mainly manifested as cracking of the blade, cracks and other damages, and then creates potential safety hazards; and in the production process of the blade, due to the problems of production technology and manual operation, there are problems such as empty rubber, wrinkles, and poor rubber in the shell during the production process. , lack of core material, gaps and other defects, and most of the defects exist in the interior of the blade material, and the type, size and degree of defects cannot be intuitively seen from the outer surface

The tower frame is composed of welded steel pipes rolled from steel plates and connected by flanges. Due to the problem
