Infrared thermal wave based non-destructive testing system for wind turbine blades

Abstract

The invention discloses an infrared thermal wave based non-destructive testing system for wind turbine blades. The system comprises a remote control aircraft, an infrared thermal wave testing component and a control component, wherein the infrared thermal wave testing component is connected with the remote control aircraft; the remote control aircraft and the infrared thermal wave testing component are respectively communicably connected with the control component; and the remote control aircraft is used for receiving a flight control command sent by the control component to convey the infrared thermal wave testing component to a preset test position according to the flight control command. The system provided by the invention has the technical effects that the collecting of real-time heatmap data of the wind turbine blades is realized to complete blade image analysis and automatically determine the type, the position and the size of a blade depth surface defect, so that an accurate and reliable data basis is provided to maintenance personnel of the wind turbine blades.

Description

technical field [0001] The invention relates to the technical field of unmanned inspection of wind turbine blades, in particular to a nondestructive detection system for wind turbine blades based on infrared thermal waves. Background technique [0002] Blades are the most critical components of wind turbines. During operation, they are absorbed by insects and dirt, sand erosion, rain erosion, and lightning strikes, causing the surface of the blades to corrode and crack, thereby increasing the operating cost of the wind turbine and bringing greater safety. Hidden dangers endanger the personal safety of wind farm operation and maintenance personnel. At the same time, with the expansion of the installed capacity of wind turbines, the size of the blades continues to increase, making it more difficult to inspect the blades. At present, the inspection methods of fan blades include telescope observation, spiderman, etc. This inspection method requires a lot of manual work and low ...

[0002] Blades are the most critical components of wind turbines. During operation, they are absorbed by insects and dirt, sand erosion, rain erosion, and lightning strikes, causing the surface of the blades to corrode and crack, thereby increasing the operating cost of the wind turbine and bringing greater safety. Hidden dangers that endanger the personal safety of wind farm operation and maintenance personnel

At the same time, with the expansion of the installed capacity of wind turbines, the size of the blades continues to increase, making it more difficult to inspect the blades

At present, the inspection methods of fan blades include telescope observation, spider man, etc. This inspection method has a large manual workload and low inspection efficiency
