Non-stop wind power blade detection device

Abstract

The invention provides a non-stop wind power blade detection device. The device comprises an image collection unit, an image processing unit, a master control unit and a server unit; the image collection unit, the image processing unit and the server unit are connected with the master control unit. The image processing unit comprises an image splicing module and an image slicing module; the serverunit comprises a defect detection module, a report generation module and a data storage module; the image collection unit comprises a vision trigger module, an image collection module and a cloud control module; the detection on the wind power blade is realized under the non-stop condition by controlling the coordinated operation of various unit by the master control unit. The technical scheme provided by the invention solves the problems that the detection result cannot be stored, the cost is high and the safety loophole is large in the prior art.

Description

technical field [0001] The present invention relates to the technical field of a detection system, in particular to a non-stop detection device for wind turbine blades. Background technique [0002] As a renewable resource, wind energy has a good development prospect and has great potential to become an important part of the future energy structure. As a device for capturing wind energy, fan blades are an important part of wind turbines, and their performance directly affects the operation and efficiency of wind power systems. [0003] Fan blades are an important part of wind turbines, and are generally made of glass fiber composite materials. Due to the harsh working environment and complex and variable working conditions, the blades of the fan will inevitably be damaged to varying degrees during operation. There are cracks, fractures, etc. External impact is the main cause of cracks, and fractures are usually caused by the accumulation of defect damage. [0004] At prese...

AI Technical Summary

Problems solved by technology

[0004] At present, the detection technologies for wind power blades mainly include telescopes for wind power blades, cranes and basket spiders for wind power blades, drones for wind power blades and other detection technologies. Among them, the telescope for wind power blades is a non-intelligent detection, and the detection results cannot be stored; The cost of inspecting wind power blades by cranes and basket spiders is high, and there are great potential safety hazards; drone inspection of wind power blades is difficult to control, prone to accidents, and is greatly affected by batteries and weather; international attempts to use non-destructive testing methods for blades include infrared , ultrasound, acoustic emission, ray, etc. These methods are currently in the laboratory research stage, and there are no norms and standards for forming. In China, most blade factories use methods such as static experiments, shape inspections, visual inspections, and knocking. for quality control

However, many defects on the surface of the blade, such as bonding, trachoma, white spots, wrinkles, and bulges, are small and hidden, and it is not easy to detect, and it is difficult to detect comprehensively through physical methods such as simple visual inspection of the shape.
