Description

Technical Field

[0001] This application relates to the field of wind power equipment testing technology, and in particular to a wind turbine blade testing device. Background Technology

[0002] Wind turbine blades are the core components of wind turbine generators, enabling energy conversion. Their paint, as a crucial layer for protection and improving aerodynamic performance, affects the efficiency, stability, and lifespan of the wind turbine generator. Therefore, video footage of the paint finish must be taken and archived before wind turbine blades leave the factory to provide a basis for tracing responsibility for any subsequent paint damage.

[0003] In related technologies, the condition of the paint on wind turbine blades is usually inspected by hand-held cameras or by drones equipped with cameras.

[0004] However, as wind turbine blades become larger, the above-mentioned testing methods are prone to delays due to process interruptions or rework, making it difficult to adapt to the pace of large-scale production and shipment. Utility Model Content

The second moving part can drive the first testing sections to move toward or away from the load-bearing component via the telescopic section. The second testing section is used to detect the vertical distance between the first testing section and the load-bearing component.

[0014] In one possible implementation, the wind turbine blade testing device provided in this application includes at least one of the column and the support beam, which comprises multiple sub-parts and multiple connecting parts. The multiple sub-parts are arranged sequentially along their own length direction, and the connecting parts are connected between two adjacent sub-parts.

[0015] In one possible implementation, the wind turbine blade inspection device provided in this application includes a plurality of first inspection units, each of which includes at least one of a laser scanner, an infrared imager, a camera, and an ultrasonic probe.

[0033] In related technologies, the condition of the paint on wind turbine blades is typically inspected and archived by hand-held cameras or by drones equipped with cameras. However, as wind turbine blades become larger, these inspection methods are prone to delays due to process interruptions or rework, making them difficult to adapt to the pace of large-scale production and shipment.

[0034] In view of this, the wind turbine blade testing device provided in this application can effectively shorten the testing time of wind turbine blades through the coordinated cooperation of the load-bearing component, the support component and the testing component, thereby adapting to the pace of large-scale production and shipment.

[0035] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] See Figure 1and Figure 2 This application provides a wind turbine blade inspection device, which may include a carrier component 100, a support component 200, and a detection component 300. The carrier component 100 carries the blade 10 to be inspected. The support component 200 spans across opposite sides of the carrier component 100 in a first direction X, and is arranged around the carrier component 100. The detection component 300 is connected to the support component 200, and at least a portion of the detection component 300 has a degree of freedom of movement and rotation relative to the support component 200. The detection component 300 is used to inspect the surface morphology of the blade 10 to be inspected. One of the carrier component 100 and the support component 200 has a degree of freedom of movement relative to the other in a second direction Y, so that the detection range of the detection component 300 can cover the blade 10 to be inspected along the second direction Y. The first direction X and the second direction Y are intersecting.

[0037] It should be noted that the first direction X can be understood as the width direction of the bearing component 100, or the chord direction of the blade 10 to be tested. The second direction Y can be understood as the length direction of the bearing component 100, or the length direction of the blade 10 to be tested.

[0038] The bearing assembly 100 serves as the foundation for the blade 10 under test and can be horizontal to ensure that the blade 10 is placed stably. Optionally, the bearing assembly 100 can be a blade support frame, a blade transfer vehicle, a blade transport semi-trailer, etc., to meet the bearing and testing requirements of the blade 10 under test.

[0039] In practice, the blade 10 to be tested can be placed on the bearing assembly 100 in a flat or oblique orientation, as long as the blade 10 to be tested is placed stably.

[0040] The support component 200 spans across the bearing component 100 on opposite sides in the first direction X, forming a stable support frame around the bearing component 100, providing a reliable installation foundation for the detection component 300. For example, the support component 200 can be configured as a portal frame, which may include columns 210 fixed on both sides of the bearing component 100 and a support beam 220 spanning above the bearing component 100, ensuring both support stability and providing sufficient detection space for the detection component 300.

[0041] It is understood that either the carrier component 100 or the support component 200 may have a degree of freedom of movement relative to the other in the second direction Y. Optionally, the carrier component 100 may be able to move relative to the support component 200 in the second direction Y, or the support component 200 may be able to move relative to the carrier component 100 in the second direction Y, thereby ensuring that the detection component 300 can cover the entire length of the blade 10 to be detected with relative movement.

[0042] It should be noted that the detection component 300 is connected to the support component 200 and has both motion and rotational degrees of freedom to flexibly adapt to the curved surface contour of the blade 10 to be inspected, accurately scanning and inspecting the surface morphology of the blade 10. For example, the detection component 300 may include a detection head, which can move along the portal frame via a linear adjustment module and can also rotate at multiple angles via a rotation adjustment module such as a multi-axis gimbal, allowing the detection head to adjust the detection angle according to the curved surface of the blade 10 at different positions, reducing the probability of detection blind spots. Optionally, the detection head can be a laser scanning detection head, a high-definition vision detection head, etc. A laser scanning detection head can acquire the surface contour data of the blade 10 to be inspected by emitting a laser beam, while a high-definition vision detection head can analyze the surface morphology by acquiring images, meeting different detection accuracy requirements. Thus, the detection component 300 can scan the surface morphology of the blade 10 to be inspected.

[0043] In some optional embodiments, a storage device may also be included. This storage device can retain surface morphology information of the blade 10 to be inspected, scanned by the detection component 300. This information may include raw image data and three-dimensional contour models collected during the inspection process, providing a basis for tracing responsibility when blade paint damage is subsequently discovered. When blade paint damage occurs, the stored surface morphology information can be retrieved and compared with the blade surface state after the damage occurred to determine whether the damage originated in the production or transportation stage.

[0044] In actual testing, the blade can be placed on the carrier component 100 first, and then one of the carrier component 100 and the support component 200 can be controlled to move along the second direction Y. If the carrier component 100 moves, it will drive the blade 10 to be tested to move at a constant speed along the second direction Y, and the detection component 300 will synchronously adjust its position and angle relative to the support component 200, collecting surface morphology data of the blade 10 in real time. If the support component 200 moves, it will drive the detection component 300 to move along the second direction Y, and the detection component 300 will continuously adapt to the curved contour of the blade 10 to complete the test. The storage device is communicatively connected to the detection component 300 and can store the surface morphology information collected by the detection component 300. Through the coordinated cooperation between the carrier component 100, the support component 200, and the detection component 300, the detection component 300 can form a continuous detection trajectory covering the entire path of the blade 10 to be tested along the second direction Y, without the need for frequent start-stop adjustments, greatly shortening the testing time and thus adapting to the rhythm of large-scale production and shipment.

[0045] In other alternative embodiments, the support component 200 may also be a gantry frame, a workshop door frame, a chain or rope with a supporting function, etc., with the purpose of supporting the detection component 300 and providing detection space. The embodiments of this application are not limited here.

[0046] See Figure 2 In some embodiments, at least a portion of the detection component 300 is movable relative to the support component 200 along at least one of a first direction X and a third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged to intersect each other.

[0047] It should be noted that the third direction Z can be understood as the height direction of the bearing component 100.

[0048] When at least a portion of the detection component 300 moves along the first direction X, it can flexibly cover different width areas of the blade 10 to be detected in the first direction X, effectively avoiding the omission of the edge, curved transition section and other parts of the blade 10 to be detected due to the detection component 300 being fixed in a single position, and reducing the probability of detection blind spots.

[0049] The design of at least part of the detection component 300 moving along the third direction Z can adapt to the undulations of the blade 10 under test in the height direction, ensuring that the detection component 300 is within the optimal detection range, avoiding the inability to effectively scan some areas due to the height fluctuations of the blade 10 under test, and reducing the probability of detection blind spots.

[0050] Furthermore, in conjunction with the relative movement of one of the rental component and the support component 200 in the second direction Y, the movement of the detection component 300 along the first direction X and the third direction Z, together with the relative movement in the second direction Y, can completely cover the curved surface profile of the blade 10 to be detected, thereby significantly reducing the probability of detection blind spots.

[0051] See Figure 1 In some embodiments, one of the support component 200 and the carrier component 100 includes a first movable element 110, which is configured to move relative to the ground to move the support component 200 or the carrier component 100 as a whole.

[0052] It is understandable that if the first moving part 110 is set on the support component 200, it can be installed at the bottom of the support component 200. The first moving part 110 can be a moving wheel, a sliding block that cooperates with the ground guide rail, etc. At the same time, a drive component (such as a servo motor) is used to provide power to the first moving part 110 to ensure that the support component 200 can move smoothly along the preset path. The first moving part 110 can also integrate a braking unit. When the support component 200 moves to the target position, the movement state is locked by the braking unit to avoid the support component 200 from accidentally shifting and affecting the detection accuracy.

[0053] If the first moving part 110 is located on the support assembly 100, it can be installed on the bottom frame of the support assembly 100. The first moving part 110 can be a caster wheel, a universal wheel, or a rolling component adapted to the ground guide rail. At the same time, the first moving part 110 on the support assembly 100 can provide real-time feedback on the movement position of the support assembly 100 through a position detection component (such as a photoelectric sensor), ensuring that the support assembly 100 can accurately stop at the preset detection position or move at a set speed, thus cooperating with the detection assembly 300 to complete continuous detection.

[0054] In some embodiments, the carrier component 100 includes a carrier surface that is curved and configured to match the blade 10 to be tested, and the carrier surface is provided with a flexible buffer layer.

[0055] It should be noted that the curved surface can be set according to the common shape curvature characteristics of wind turbine blades, which can fit with the outer surface of the blade 10 to be tested, enhance the stability of the blade 10 to be tested on the bearing component 100, reduce the probability of the blade 10 to be tested shifting during the test, and provide a stable foundation for the subsequent test component 300 to accurately collect surface morphology information.

[0056] The bearing surface can also be provided with a flexible buffer layer. This flexible buffer layer can be made of materials with a certain degree of elasticity and wear resistance, such as rubber or polyurethane. It not only further fills the tiny gaps between the curved surface and the surface of the blade 10 to be tested, improving the tightness of the fit, but also acts as a buffer during the placement of the blade 10 onto the bearing surface, effectively preventing scratches and bumps on the paint surface of the blade 10. Furthermore, the flexible buffer layer can reduce the relative friction between the blade 10 and the bearing surface.

[0057] In some alternative embodiments, the carrier component 100 includes a pair of positioning protrusions arranged along a first direction X, the positioning protrusions being used to limit the blade 10 to be tested.

[0058] It should also be noted that the positioning protrusions on each side can be arranged at intervals along the second direction Y to limit the blade 10 to be tested. Optionally, the side of the positioning protrusion facing the blade 10 to be tested can be set to a shape that matches the side profile of the blade 10 to be tested.

[0059] By using paired positioning protrusions, the blade 10 to be tested can be bidirectionally limited from the first direction X, effectively preventing the blade 10 to be tested from moving along the first direction X during the testing process, further improving the stability of the blade on the bearing component 100, and ensuring that the blade 10 to be tested is within the effective testing range of the testing component 300.

[0060] See Figure 1 and Figure 2 In some embodiments, the support assembly 200 includes a pair of columns 210 arranged in a first direction X and a support beam 220 connected between the columns 210, and the detection assembly 300 is connected to at least one of the columns 210 and the support beam 220.

[0061] The paired columns 210 are respectively arranged on opposite sides of the support component 100 along the first direction X. The columns 210 can be made of high-strength square tubing, aluminum alloy profiles, etc. The extension height of the columns 210 in the third direction Z can be set to be greater than or equal to 5m, thereby providing sufficient detection space for the detection component 300 and reducing the probability of collision between the detection component 300 and the blade 10 to be detected. The bottom of the columns 210 can be adapted to different structures according to the movement requirements. For example, when the support component 200 needs to move relative to the ground via the first moving part 110, the bottom of the columns 210 can be fixedly connected to the first moving part 110, and the first moving part 110 drives the support component 200 to move smoothly as a whole. When the support component 200 is set to not move, the bottom of the columns 210 can be directly fixedly connected to the ground, and the connection stability with the ground is enhanced by fastening components (such as expansion bolts) to prevent the support component 200 from shifting during detection.

[0062] In practice, the two ends of the support beam 220 can be connected to one of the columns 210 respectively. The support beam 220 can be made of high-strength square tube, aluminum alloy profile, etc. The horizontal extension length of the support beam 220 can be set to be greater than or equal to 10m, so as to form a portal frame spanning above the load-bearing component 100 together with the column 210, so as to provide a stable installation foundation for the detection component 300 and reserve sufficient space for the placement and detection of the blade 10 to be detected.

[0063] Optionally, the detection component 300 can be connected to the column 210, the support beam 220, or both. For example, the detection component 300 can be connected to both the column 210 and the support beam 220 to expand the detection coverage. When a portion of the detection component 300 is connected to the support beam 220, the movement of the detection component 300 along the first direction X can be achieved through a sliding engagement between the portion of the detection component 300 and the support beam 220. When a portion of the detection component 300 is connected to the column 210, the movement of the detection component 300 along the third direction Z can be achieved through a sliding engagement between the portion of the detection component 300 and the column 210. This configuration allows for flexible adjustment of the position of the detection component 300 and ensures its stability through the rigid support of the column 210 and the support beam 220. Furthermore, the relative movement of the support component 200 and the load-bearing component 100 expands the detection coverage.

[0064] In some embodiments, the support assembly 200 further includes a second movable member connected to a portion of the detection assembly 300. The second movable member is movably connected to either the column 210 or the support beam 220. The second movable member is provided with a locking member for locking the relative position between the second movable member and the column 210 or the support beam 220.

[0065] It should be noted that the detection component 300 can move relative to the support component 200 via a second movable member. For example, the second movable member can be connected to the column 210, and the surface of the column 210 can be provided with a guide structure, which may include a groove, guide rail, etc. The second movable member can move along a third direction Z by sliding or rolling, thereby driving the detection component 300 to move relative to the column 210 along the third direction Z. The second movable member can also be connected to the support beam 220, and the surface of the support beam 220 can also be provided with a guide structure. The second movable member moves relative to the support beam 220 along a first direction X by cooperating with the guide structure, thereby driving the detection component 300 to move relative to the support beam 220, so that the detection component 300 can adapt to different specifications of the blade 10 to be detected and different positions of the blade 10 to be detected, thereby ensuring the detection effect.

[0066] Optionally, the second moving part can be a moving trolley, and the side of the moving trolley connected to the column 210 and / or support beam 220 can be provided with a slider, roller, etc.

[0067] The second moving part can be equipped with a locking element. This locking element is used to lock the relative position between the second moving part and the column 210 or support beam 220, ensuring that the detection component 300 remains stable after being adjusted to the target position. The locking element can be a mechanical locking structure, such as a locking bolt that threads with the second moving part. The end of the locking bolt abuts against the surface of the column 210 or support beam 220, using friction to fix the second moving part. Alternatively, an electromagnetic lock can be used, which uses electromagnetic force to attract and fix the second moving part, and allows for remote locking and releasing via a control component.

[0068] See Figure 1 and Figure 2 In some embodiments, the detection component 300 includes a plurality of first detection parts 310 and a universal adjustment seat. The first detection parts 310 are correspondingly connected to the second moving member through the universal adjustment seat. The second moving member includes a telescopic part and a second detection part. The second moving member can drive the first detection parts 310 to move toward or away from the support component 100 through the telescopic part. The second detection part is used to detect the vertical distance between the first detection parts 310 and the support component 100.

[0069] Understandably, the first detection unit 310 can be connected to the second moving part via a universal adjustment seat. Optionally, two, three, or more first detection units 310 can be provided, and each first detection unit 310 can be arranged at intervals along the extension direction of the column 210 and the support beam 220, so that the detection range of the detection assembly 300 can cover different areas of the surface of the blade 10 to be detected, reducing the frequency of reciprocating movement of a single first detection unit 310 and improving detection efficiency.

[0070] The universal adjustment seat, as a structure connecting the first detection unit 310 and the second moving part, has multiple degrees of rotational freedom, which can drive the first detection unit 310 to rotate flexibly, so that the detection end face of the first detection unit 310 can always adapt to the curved surface profile of the blade 10 to be detected, reduce the detection angle deviation caused by the change of the curvature of the blade 10 to be detected, and thus effectively reduce the detection blind zone.

[0071] It should be noted that the second moving part may also include a telescopic part and a second detection part. The second moving part can drive the first detection part 310 to move toward or away from the bearing component 100 through the telescopic part. The telescopic part can be a ball screw, hydraulic telescopic cylinder, pneumatic telescopic rod, electric push rod, etc. Its telescopic action can adjust the distance between the first detection part 310 and the surface of the blade 10 to be tested, so that the first detection part 310 can be quickly adjusted to the preset detection distance before testing. It can also finely adjust the distance in real time according to the undulation of the surface of the blade 10 to be tested during the testing process to prevent the first detection part 310 from colliding with the surface of the blade 10 to be tested, and at the same time avoid the detection data being blurred due to excessive distance.

[0072] The second detection unit can be integrated on the second moving part to detect the vertical distance between the first detection unit 310 and the bearing component 100. It can collect distance data in real time and feed it back to the control component. The control component can automatically adjust the extension and retraction of the telescopic part according to the distance data to ensure that the first detection unit 310 is kept within the preset detection distance range, thereby improving the automation and accuracy of the detection process, and at the same time improving the adaptability and reliability of the detection component 300.

[0073] Optionally, the second detection unit may include one of a laser rangefinder, an ultrasonic rangefinder, or an infrared rangefinder. The laser rangefinder can obtain the vertical distance between the first detection unit 310 and the target by emitting a laser beam onto the surface of the support assembly 100 or the blade 10 to be detected, receiving the reflected beam, and calculating the propagation time. The ultrasonic rangefinder can calculate the vertical distance by emitting ultrasonic waves, receiving the reflected waves, and using the sound wave propagation time. The infrared rangefinder can measure the distance by emitting infrared light and detecting changes in the intensity of the reflected light.

[0074] See Figure 2 In some embodiments, at least one of the column 210 and the support beam 220 includes a plurality of sub-parts 200a and a plurality of connecting parts 200b, the plurality of sub-parts 200a being arranged sequentially along their own length direction, and the connecting parts 200b being connected between two adjacent sub-parts 200a.

[0075] It is understandable that by setting multiple sub-parts 200a and multiple connecting parts 200b, the overall length and angle of the column 210 or support beam 220 can be flexibly adjusted according to actual needs, while facilitating installation and maintenance. Multiple sub-parts 200a can adopt the same or compatible cross-sectional shapes, thereby ensuring the consistency and rigidity of the overall structure after splicing. For example, sub-parts 200a can be selected as rectangular tubes, circular tubes, or other profiles, and the material can be high-strength alloys, steel, etc., to ensure that each sub-part 200a has sufficient load-bearing capacity and avoids deformation when supporting the detection component 300. For example, the extension length of each sub-part 200a can be set between 1.5m and 3m. Therefore, the column 210 can include at least three sub-parts 200a, and the support beam 220 can include at least five sub-parts 200a.

[0076] The connecting part 200b serves as a connecting component between adjacent sub-parts 200a and may include a rotary joint to allow the adjacent sub-parts 200a to rotate relative to each other, thereby adjusting the angle between the sub-parts 200a. When the sub-parts 200a extend to a preset height or angle, the two adjacent sub-parts 200a may be fixed by means of snap-fitting, inserting pins into preset holes, etc.

[0077] In some alternative embodiments, when the sub-component is a tubular structure, the connecting part 200b may also be a plug-in component with both ends inserted into the inner cavity of the adjacent sub-component 200a, and fastened with a positioning pin and bolt.

[0078] Therefore, by assembling the column 210 or support beam 220 with multiple sub-units 200a and connecting parts 200b, the overall length can be adjusted by increasing or decreasing the number of sub-units 200a to accommodate blades of different specifications, flexibly adapting to the inspection space or the inspection requirements of the special curved surface of the blade 10 to be inspected. At the same time, the disassembled sub-units 200a are easy to transport, reducing transportation difficulty and cost. Furthermore, when a sub-unit 200a is damaged, it can be replaced individually, reducing maintenance costs. The standardized design of the connecting parts 200b also ensures the interchangeability of the sub-units 200a, improving versatility and expandability.

[0079] See Figure 1 and Figure 2 In some embodiments, the detection component 300 includes a plurality of first detection units 310, each of which includes at least one of a laser scanner, an infrared imager, a camera, and an ultrasonic probe.

[0080] Optionally, the plurality of first detection units 310 may include one or more of the following: a laser scanner, an infrared imager, a camera, and an ultrasonic probe. For example, the first detection unit 310 may be a camera.

[0081] Among them, the laser scanner can quickly acquire the three-dimensional contour data of the surface of the blade 10 to be inspected by emitting a laser beam and receiving the reflected signal, and accurately identify physical morphological defects such as protrusions, depressions, and cracks on the surface; the infrared imager can indirectly reflect defects such as delamination and bubbles under the paint by capturing the temperature distribution differences on the surface of the blade 10 to be inspected; the camera can intuitively record appearance defects such as paint damage and scratches on the surface of the blade 10 to be inspected by acquiring high-resolution images; and the ultrasonic probe can detect defects such as cracks on the surface of the blade 10 to be inspected by emitting ultrasonic waves and receiving the reflected waves.

[0082] Optionally, the camera can be a high-definition 4K or higher resolution camera to ensure shooting quality.

[0083] Therefore, the first inspection unit 310 is connected to the second moving part through the universal adjustment seat, which flexibly adjusts the inspection angle and position to ensure that accurate inspection results can be obtained in all areas of the complex curved surface of the blade 10 to be inspected, thereby meeting the requirements of process inspection and shipment inspection.

[0084] See Figure 1 and Figure 2 In some embodiments, the detection component 300 further includes a plurality of supplementary lighting units 320, and supplementary lighting units 320 are disposed between at least one group of adjacent first detection units 310.

[0085] By incorporating a supplementary lighting unit 320, the problem of blurred detection caused by surface undulations, material reflection, or uneven ambient light on the surface of the blade 10 under inspection can be effectively solved, ensuring that the first inspection unit 310 can stably acquire clear and accurate surface morphology information. The supplementary lighting unit 320 can select an appropriate light source type according to the type of adjacent first inspection units 310 and the inspection requirements. For example, between cameras, the supplementary lighting unit 320 can use a high color rendering LED surface light source to provide uniform and soft light through diffuse reflection, reducing the shadows formed by the curved surface of the blade 10 under inspection and avoiding localized over-darkness that would prevent the identification of details such as paint scratches and color differences.

[0086] It should also be noted that the installation position and angle of the supplementary lighting unit 320 can be flexibly adjusted. It maintains a preset distance from the adjacent first detection unit 310 to avoid blocking the detection path. At the same time, the direction of illumination can be adjusted by the universal adjustment seat to optimize the light projection angle for the tilt angle of the curved surface of the blade 10 to be detected, so as to improve the detection effect of the detection component 300.

[0087] For example, at least three first detection units 310 may be provided on the support beam 220, and a supplementary lighting unit 320 may be installed between every two adjacent first detection units 310. At least one first detection unit 310 and at least one supplementary lighting unit 320 may be provided on the column 210. The supplementary lighting unit 320 may also be connected to the second moving member via a universal adjustment seat, thereby realizing movement in the first direction X or the third direction Z.

[0088] In some embodiments, the system further includes a control unit, a display unit, and a storage unit that are communicatively connected to each other. The control unit is communicatively connected to at least one of the carrier component 100, the support component 200, and the detection component 300. The storage unit is used to store surface morphology information collected by the detection component 300, and the display unit is used to display the surface morphology information.

[0089] By setting up control components, display components, and storage components, the detection process can be automatically controlled and the information can be managed throughout the entire process, greatly improving the intelligence level and ease of operation of the detection device.

[0090] The control component can establish a connection with the bearing component 100, the support component 200, and the detection component 300 via wired or wireless communication, receive status signals from each component (such as the position information of the bearing component 100 and the working parameters of the detection component 300), and send control signals according to a preset program or operator's instructions, such as controlling the bearing component 100 to move at a constant speed along the second direction Y, adjusting the position of the second moving part on the support component 200, or driving the universal adjustment seat to rotate the detection component 300.

[0091] The storage device receives surface morphology information transmitted in real time from the detection component 300 via a communication connection, including but not limited to surface morphology images, detection time, blade number, detection location, and other related information. This data can be stored in a structured format for easy retrieval later, providing a complete basis for blade quality traceability.

[0092] The display unit shows the surface morphology information stored in the storage unit in real time or in playback through a visual interface, allowing operators to intuitively view the surface morphology information of the blade 10 to be inspected. The display unit can also show the real-time working status of each component (such as the moving speed of the bearing component 100 and the current position of the detection component 300), and supports operators to input adjustment commands to the control unit through the display interface to realize human-machine interaction.

[0093] Alternatively, the display device can be a desktop computer, a laptop computer, or the like.

[0094] Understandably, the coordinated operation of control, display and storage components not only simplifies the operational complexity of the testing process and reduces errors caused by human intervention, but also ensures that the testing process is monitorable, data is traceable and results are analyzable through real-time transmission, storage and display of information, thereby improving the efficiency and reliability of blade testing and better adapting to the quality control needs of large-scale production.

[0095] In practice, the blade 10 to be inspected can be placed on the carrier component 100 and its surface cleaned. Simultaneously, surrounding obstacles should be cleared to ensure a clear inspection path. The relative positions of the support component 200 and the carrier component 100 are determined, and the inspection component 300 is assembled on the support component 200. After assembling all components and establishing the necessary communication connections, the inspection component 300 is activated. The inspection component 300 is adjusted according to the scanning requirements, and the number or set number of the blade 10 to be inspected is input. Then, one of the carrier component 100 and the support component 200 is moved relative to the other along the second direction Y. The position or angle of the inspection component 300 is adjusted in real time according to the scanning progress to ensure that the inspection range covers the blade 10 and that the inspection results are sufficiently clear. When an anomaly is detected, the movement direction and speed of one of the bearing component 100 and the support component 200 relative to the other can be adjusted. Screenshots of key areas of the blade 10 to be inspected can be taken, such as the blade root interface area, the marking and coating area, and the blade tip support position. After scanning all of the blade 10, the inspection component 300 is shut down, and the storage device stores the surface morphology information. Personnel can review the inspection results and, after inspecting the paint quality segment by segment, store the surface morphology information (such as video files) in a database according to the blade 10's number or kit number to ensure long-term secure backup and convenient retrieval.

This application can quickly and safely inspect the surface morphology of wind turbine blades, effectively reducing the safety risks associated with manual shooting at height. Furthermore, this application can meet the process inspection and shipment inspection needs of wind turbine blades of different specifications.
