Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a wind turbine blade appearance inspection device. Background Technology

[0002] Wind power generation, as a promising clean energy utilization method, occupies a key position in the global energy transition. With continuous technological innovation, wind turbine generators are constantly moving towards larger sizes and higher efficiency. As the core component for capturing wind energy, the quality of wind turbine blades directly affects the performance, power generation efficiency, and operational stability of the wind turbine generator. Therefore, wind turbine blades need to undergo appearance inspection before leaving the factory.

[0003] Currently, existing testing devices have significant drawbacks when inspecting wind turbine blades. Most devices involve moving the blades inside the testing unit for inspection. However, wind turbine blades are generally quite long, with large blades reaching tens or even hundreds of meters in length, and their weight is considerable. Moving such large and heavy blades is extremely risky, potentially causing direct damage to the blade surface. Therefore, extreme caution is required when moving the blades, which not only increases the difficulty and risk of operation but also prolongs the testing cycle, hindering safe and efficient inspection of wind turbine blades.

[0004] Therefore, it is necessary to invent a wind turbine blade appearance inspection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a wind turbine blade appearance inspection device to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade appearance inspection device, comprising an inspection component and multiple support components arranged in a linear array, wherein the multiple support components are spliced ​​together for use, each support component includes a movable base, each of the four corners of the bottom of the movable base is equipped with a self-locking roller, and each of the two ends of the top of the movable base is fixedly connected to a gantry frame, one of the gantry frames is equipped with a positioning sleeve on its top, and the other gantry frame is equipped with a positioning pin on its top, the positioning pin matching the positioning sleeve, each of the two outer walls of one gantry frame is fixedly connected with a limiting post, and each of the two outer walls of the other gantry frame is rotatably connected with a connector, one end of the connector having a slot that matches the limiting post, the inner top surfaces of the two gantry frames are fixedly connected with an I-beam, and an electric hoist trolley is slidably connected directly below the I-beam of one of the support components, the inspection component being positioned directly below the electric hoist trolley.

[0007] The basic framework of the detection device is formed by multiple support components arranged in a linear array and that can be spliced ​​together. This design allows the device to be flexibly adjusted in size according to wind turbine blades of different lengths, improving the device's versatility and adaptability.

[0008] Preferably, two adjacent bracket assemblies are positioned by inserting a positioning pin into a positioning sleeve, and two adjacent bracket assemblies are limited by engaging a slot on their connector with a limiting stake.

[0009] The insertion of the positioning pin and the positioning sleeve can quickly and accurately determine the relative position between the support components, while the locking of the slot and the limiting stake further prevents the relative movement of the support components after splicing, ensuring the stability of the entire testing device structure. This provides a reliable guarantee for the stable operation of the testing components and helps to improve the accuracy of the testing results.

[0010] Preferably, the detection assembly includes a circular loading frame for mounting on the outside of the wind turbine blades, the circular loading frame being installed directly below the electric hoist trolley, and six industrial cameras arranged in a circular array mounted on the inner wall of the circular loading frame.

[0011] Using six industrial cameras, the wind turbine blades can be captured from different angles, avoiding blind spots caused by a single shooting angle. This allows for more accurate detection of various defects on the blade surface, such as cracks, scratches, and dents, greatly improving the comprehensiveness and accuracy of the inspection.

[0012] Preferably, a controller is installed on the outer wall of one side of the gantry of one of the support assemblies, and the electric hoist trolley and the industrial camera are wirelessly connected to the controller through their respective built-in wireless communication modules.

[0013] This wireless connection method breaks free from the constraints of traditional wired connections, reduces the complexity and limitations of wiring layout, and makes the device layout more flexible.

[0014] Preferably, when the industrial camera is working, it first captures images of the wind turbine blades to obtain raw image information. Then, the industrial camera uses its own image processing chip to perform preliminary processing and compression on this image information to reduce the amount of data. Finally, the processed image information is sent to the controller through the wireless communication module according to a specific communication protocol.

[0015] After receiving the image information sent by the industrial camera, the controller will further analyze and process it, and compare it with the preset standard image to determine whether there are defects such as cracks, scratches, and dents on the surface of the wind turbine blade.

[0016] Preferably, each of the four corners of the circular loading frame is fixedly connected to an auxiliary rod, and each auxiliary rod is equipped with a set of movable rollers at its bottom.

[0017] The design of the auxiliary rod and the moving roller provides additional support and guidance for the movement of the detection component. As the detection component moves with the electric hoist trolley, the moving roller can roll on the corresponding track, sharing some of the weight and reducing the burden on the electric hoist trolley. This makes the movement of the detection component smoother and more stable, reducing shaking and deviation during the movement. It also helps the industrial camera to obtain clearer and more accurate images, thus improving the accuracy of the detection.

[0018] Preferably, four L-shaped track beams are fixedly connected between the inner walls of the two gantry frames, and four sets of movable rollers are respectively tumblingly connected to the four L-shaped track beams.

[0019] The L-shaped track beam provides a clear movement path for the moving roller, ensuring the directional stability of the moving roller during movement and further guaranteeing that the detection component moves accurately along the predetermined trajectory.

[0020] Preferably, after the multiple support components are spliced ​​together, the I-beams and L-shaped track beams on them are also spliced ​​together, so that the electric hoist trolley driven by the controller can move the detection component between the multiple support components, thereby performing a comprehensive appearance inspection of the wind turbine blades.

[0021] By centrally controlling the electric hoist trolley and industrial camera through the controller, automated inspection of wind turbine blades can be achieved.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. When using this utility model, the appropriate number of support components can be selected according to the length of the wind turbine blade, and then these support components are moved one by one to fit over the outside of the blade. Only one support component is moved at a time, which is flexible and convenient to operate. It can effectively avoid collision with the blade, reduce the difficulty and risk of operation, and is safer and more efficient than the traditional method of moving the blade for inspection.

[0024] 2. The controller controls the electric hoist carriage to move on the I-beam, which in turn drives the industrial camera on the inspection component to move and take pictures along the surface of the wind turbine blade, thereby achieving a comprehensive appearance inspection of the wind turbine blade.

Six industrial cameras 14 arranged in a circular array are installed on the inner wall of the circular loading frame 13. A controller 15 is installed on the outer wall of one side of the gantry 5 of one of the support assemblies 2. The electric hoist trolley 12 and the industrial cameras 14 are wirelessly connected to the controller 15 through their respective built-in wireless communication modules.

[0038] The industrial camera 14 first captures images of the wind turbine blades to obtain raw image information. Then, it uses its own image processing chip to perform preliminary processing and compression on these image information to reduce the amount of data.

After receiving the image information sent by the industrial camera 14, the controller 15 will further analyze and process it. By comparing it with a preset standard image, it will determine whether there are defects such as cracks, scratches, and dents on the surface of the wind turbine blades.
