A non-stop detection device for wind turbine blades

Abstract

The invention provides a non-stop wind power blade detection device. The device of the present invention comprises: an image acquisition unit, an image processing unit, a main control unit and a server unit, and the image acquisition unit, the image processing unit and the server unit are all connected to the main control unit. The image processing unit includes an image splicing module and an image cutting module, and the server unit includes a defect detection module, a report generation module and a data storage module. The image acquisition unit includes a visual trigger module, an image acquisition module, and a pan / tilt control module. The main control unit controls the coordinated operation of each unit to realize the detection of wind turbine blades without stopping the machine. The technical scheme of the invention solves the problems in the prior art that the detection results cannot be stored, the cost is high, and the safety hazard is great.

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.
