Description

Technical Field

[0001] This invention relates to the field of wind turbine testing technology, specifically to a non-destructive testing device for wind turbine nacelle components. Background Technology

[0002] The internal structure of a wind turbine nacelle is complex, containing multiple key components such as gearboxes, generators, and brakes. The operating status of these components directly affects the power generation efficiency and safety stability of the wind turbine. Therefore, regular non-destructive testing of nacelle components is an important part of wind turbine operation and maintenance.

[0003] Existing non-destructive testing (NDT) methods for wind turbine nacelle components mostly rely on manual handheld testing equipment or fixed testing devices. The narrow space within the nacelle makes comprehensive testing difficult. Fixed testing devices, on the other hand, lack flexibility in angle adjustment and can typically only test specific areas. When testing components in different locations, the device must be disassembled and reassembled, resulting in cumbersome operations and low testing efficiency, failing to meet the demands for efficient and comprehensive testing. Therefore, we propose a new NDT device for wind turbine nacelle components. Summary of the Invention

[0004] The purpose of this invention is to provide a non-destructive testing device for wind turbine nacelle components, to solve the problems of limited testing range and inconvenient angle adjustment in existing testing equipment mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a non-destructive testing device for wind turbine nacelle components, comprising a mounting plate; The guide component one includes a mounting block, which is fixedly connected to one side of the mounting plate one. A rotating block is fixedly connected to one side of the mounting block. A rotating rod one is rotatably connected inside the rotating block. A worm gear is fixedly connected to the side surface of the rotating rod one. A rotating frame is rotatably connected to the side surface of the rotating rod one. The rotating frame is located outside the rotating block. A mounting plate two is fixedly connected to one side of the rotating frame. When using this device, a dual-dimensional angle adjustment system is constructed through the coordinated cooperation of guide component one and power component one, and guide component two and power component two. Guide component one and power component one are responsible for driving the camera to achieve vertical angle deflection, while guide component two and power component two are responsible for horizontal angle control. This allows the camera to rotate at multiple angles in three-dimensional space. At the same time, with the excellent deformation characteristics of the universal tube, the overall position of the equipment can be flexibly fine-tuned, allowing the camera to easily cover component areas at different heights and orientations inside the wind turbine nacelle, completely solving the problems of limited detection range and blind spots in traditional equipment. The first fixing component includes two connecting rings, which are fixedly connected to opposite sides of the rotating frame. Each of the two connecting rings has a number of teeth fixedly connected inside.

[0005] More preferably, the fixing component one further includes two rotating rods two, which are fixedly connected to opposite ends of the rotating rod one, and two elastic frames are fixedly connected to the side surfaces of the two rotating rods two respectively.

[0006] More preferably, a locking block is fixedly connected to each of the opposite sides of the elastic frame, and the outer side of the locking block engages with the outer side of the tooth. A power component is provided on one side of the mounting plate to prevent the camera from shifting at an angle due to equipment vibration or slight collision during the detection process, thereby ensuring the stability of the detection image and providing clear and accurate image data support for subsequent defect identification.

[0007] More preferably, the power assembly includes a mounting bracket, which is fixedly connected to the outside of the mounting block. A micro motor is fixedly connected to the outside of the mounting bracket, and a worm gear is fixedly connected to the transmission end of the micro motor.

[0008] More preferably, the outer side of the worm gear is meshed with the outer side of the worm wheel, and a protective frame is provided on the outer side of the micro motor and the worm gear, and the outer side of the protective frame is fixedly connected to the outer side of the mounting block.

[0009] More preferably, a guide component two is provided on one side of the mounting plate one, the structure of the guide component two is the same as that of the guide component one, a fixing component two is provided on the outside of the guide component two, the fixing component two is the same as that of the fixing component one, a power component two is provided on the outside of the guide component two, the outside of the power component two is the same as that of the power component one, and a mounting rod is fixedly connected to one side of the mounting plate two.

[0010] More preferably, a camera is fixedly connected to one side of the mounting rod, and a protective shell is provided on the outside of the camera. The protective shell is fitted onto the side surface of the mounting rod, effectively avoiding the inconvenience and safety hazards caused by working in the confined space inside the cabin.

[0011] In a further preferred embodiment, a universal tube is provided at the bottom of the guide component two, and a controller is provided on the outside of the universal tube. The controller is electrically connected to the micro motor and the camera. In conjunction with the excellent deformation characteristics of the universal tube, the overall position of the equipment can be flexibly and finely adjusted, so that the camera can easily cover the component areas at different heights and in different directions inside the wind turbine nacelle, completely solving the problem of limited detection range and blind spots of traditional equipment.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when using the device, a dual-dimensional angle adjustment system is constructed through the coordinated cooperation of guide component one and power component one, and guide component two and power component two. Guide component one and power component one are responsible for driving the camera to achieve vertical angle deflection, while guide component two and power component two are responsible for horizontal angle control. This enables the camera to rotate at multiple angles in three-dimensional space. At the same time, with the excellent deformation characteristics of the universal joint, the overall position of the device can be flexibly fine-tuned, allowing the camera to easily cover component areas at different heights and orientations within the wind turbine nacelle, completely solving the problems of limited detection range and blind spots in traditional equipment.

[0013] In this invention, during testing, the operator can send the equipment into the cabin through a universal joint without entering the cabin. All operations, such as camera startup, angle adjustment, and start / stop, can be completed using an external controller. This effectively avoids the inconvenience and safety risks associated with working in the confined space of the cabin. Compared to traditional testing methods that require manual handling of the equipment or repeated disassembly and reassembly of the fixing devices, this equipment significantly simplifies the testing process, reduces operating steps, significantly reduces manual labor intensity, and greatly improves testing efficiency while shortening the testing time for a single unit.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-6 The present invention provides a technical solution: a non-destructive testing device for wind turbine nacelle components, including a mounting plate 1; Guide component 1 2 includes a mounting block 201, which is fixedly connected to one side of mounting plate 1. A rotating block 202 is fixedly connected to one side of the mounting block 201. A rotating rod 1 203 is rotatably connected inside the rotating block 202. A worm gear 204 is fixedly connected to the side surface of the rotating rod 1 203. A rotating frame 205 is rotatably connected to the side surface of the rotating rod 1 203. The rotating frame 205 is located outside the rotating block 202. A mounting plate 206 is fixedly connected to one side of the rotating frame 205. The rotation of the rotating rod 1 203 simultaneously drives the rotating frame 205 to rotate around the rotating block 202. The mounting plate 206 on one side of the rotating frame 205 and the subsequently connected mounting rod 8 and camera 9 then complete the up and down angle adjustment.

[0018] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fixing component 3 includes two connecting rings 301, which are fixedly connected to opposite sides of the rotating frame 205. Several teeth 302 are fixedly connected inside each of the two connecting rings 301. The fixing component 3 also includes two rotating rods 303, which are fixedly connected to opposite ends of the rotating rod 203. Two elastic frames 304 are fixedly connected to the side surfaces of the two rotating rods 303, and locking blocks 305 are fixedly connected to opposite sides of the elastic frames 304. The outer side of the locking blocks 305 engages with the outer side of the teeth 302. A power component 4 is provided on one side of the mounting plate 1. When the rotating rod 203 rotates, it drives the rotating rods 303 at both ends to rotate synchronously. The elastic frames 304 on the rotating rods 303 are then subjected to force, causing the locking blocks 305 to disengage from the teeth 302 of the connecting rings 301, thus releasing the fixing component 3 from limiting the rotating frame 205.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, the power assembly 4 includes a mounting bracket 401, which is fixedly connected to the outside of the mounting block 201. A micro motor 402 is fixedly connected to the outside of the mounting bracket 401. A worm gear 403 is fixedly connected to the transmission end of the micro motor 402. The outside of the worm gear 403 meshes with the outside of the worm wheel 204. A protective frame 404 is provided on the outside of the micro motor 402 and the worm gear 403. The outside of the protective frame 404 is fixedly connected to the outside of the mounting block 201. When it is necessary to adjust the up and down angle of the camera 9 to detect different areas, the operator sends a start command to the power assembly 4 through the controller 12. The micro motor 402 in the power assembly 4 starts to run, and its transmission end drives the worm gear 403 to rotate synchronously. Since the worm gear 403 meshes with the worm wheel 204 on the rotating rod 203 in the guide assembly 2, the rotation of the worm gear 403 is converted into the rotation of the worm wheel 204, which in turn drives the rotating rod 203 to rotate inside the rotating block 202.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a guide component 2 5 is provided on one side of the mounting plate 1. The structure of guide component 2 5 is the same as that of guide component 1 2. A fixing component 2 6 is provided on the outside of guide component 2 5. The fixing component 2 6 has the same structure as that of fixing component 1 3. A power component 2 7 is provided on the outside of guide component 2 5. The outside of power component 2 7 has the same structure as that of power component 1 4. A mounting rod 8 is fixedly connected to one side of the mounting plate 2 2 0 6. Power component 2 7 is activated by controller 12. Since the structures of power component 2 7, guide component 2 5, and fixing component 2 6 are the same as those of power component 1 4, guide component 1 2, and fixing component 1 3, respectively, the above angle adjustment and fixing process will be repeated, driving camera 9 to complete the precise adjustment of the left and right angles.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a camera 9 is fixedly connected to one side of the mounting rod 8. A protective shell 10 is provided on the outside of the camera 9. The protective shell 10 is fitted onto the side surface of the mounting rod 8. A universal tube 11 is provided at the bottom of the guide assembly 2 5. A controller 12 is provided on the outside of the universal tube 11. The controller 12 is electrically connected to the micro motor 402 and the camera 9. The operator first starts the camera 9 through the controller 12. After ensuring that its imaging is normal, the camera 9 together with the protective shell 10 is placed in the area of ​​the component to be inspected in the wind turbine nacelle through the deformation characteristics of the universal tube 11. At this time, the protective shell 10 effectively protects the camera 9 and avoids damage from external collisions in the early stage of inspection.

[0022] The method of use and advantages of this invention: The non-destructive testing equipment for wind turbine nacelle components operates as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the operator first activates the camera 9 via the controller 12. After ensuring normal imaging, the camera 9, along with the protective housing 10, is placed inside the wind turbine nacelle into the area of ​​the component to be inspected, utilizing the deformation characteristics of the universal joint 11. At this time, the protective housing 10 effectively protects the camera 9, preventing damage from external impacts during the initial inspection. When the camera 9 needs to be adjusted in height for inspection of different areas, the operator sends a start command to the power assembly 4 via the controller 12. The micro motor 402 in the power assembly 4 starts running, and its transmission end drives the worm gear 40. 3. Synchronous rotation: Since the worm 403 meshes with the worm wheel 204 on the rotating rod 203 in the guide assembly 2, the rotation of the worm 403 is converted into the rotation of the worm wheel 204, which in turn drives the rotating rod 203 to rotate inside the rotating block 202. When the rotating rod 203 rotates, it will drive the rotating rods 303 at both ends to rotate synchronously. The elastic frame 304 on the rotating rod 303 is then subjected to force, causing the locking block 305 to disengage from the teeth 302 of the connecting ring 301, releasing the limitation of the fixing assembly 3 on the rotating frame 205. The rotation of the rotating rod 203 simultaneously drives the rotating frame 205 to rotate around. When block 202 rotates, the mounting plate 206 on one side of the rotating frame 205, along with the subsequently connected mounting rod 8 and camera 9, adjust their vertical angle accordingly. Once the angle is adjusted to the target position, the operator shuts off the micro motor 402 of power component 4 via controller 12. The elastic frame 304 returns to its original shape, pushing the locking block 305 to re-engage with the teeth 302 in the connecting ring 301, thus fixing the rotating frame 205 and ensuring that the camera 9 is stable at that angle for detection. When it is necessary to adjust the horizontal angle of the camera 9, power component 7 is activated via controller 12. Due to the operation of power component 7... The structures of guide component 2 5 and fixing component 2 6 are the same as those of power component 1 4, guide component 1 2, and fixing component 1 3, respectively. They will repeat the above angle adjustment and fixing process, driving the camera 9 to complete the precise adjustment of the left and right angles. During the entire inspection process, the universal tube 11 can assist in flexible position fine adjustment. In conjunction with the angle adjustment functions of guide component 1 2 and guide component 2 5, the camera 9 can achieve comprehensive coverage inspection of different areas of the cabin components. The inspection images acquired by the camera 9 are transmitted to the controller 12 in real time. The staff can observe and record the inspection data through the controller 12.
