Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, specifically a wind turbine tower roundness detection device. Background Technology

[0002] Wind turbine towers are the supporting structures for wind turbine generators. They are typically made of steel, cylindrical in shape, and can reach heights of tens to hundreds of meters. Their cost accounts for about 10% of the construction cost of onshore wind power and about 5% of the construction cost of offshore wind power. The tower's interior contains components such as ladders, platforms, and cable supports, and its exterior is coated with an anti-corrosion coating to extend its service life.

[0003] Regarding the aforementioned and existing related technologies: When it is necessary to detect the roundness of wind turbine towers, ultrasonic sensors are used to measure the position between the sensor and the tower. The data is then transmitted to a computer for analysis using a model to determine the roundness of the tower. However, due to the lack of a dedicated support mechanism for roundness detection, improper sensor positioning can easily affect the accuracy of the detection. Therefore, this paper proposes a wind turbine tower roundness detection device to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The wind turbine tower roundness detection device of this utility model includes a pad, a cylinder and a moving device. Two drive motors are fixedly connected to the surface of the pad, and two support rollers are rotatably connected to the inner wall of the pad. The output end of the drive motor is fixedly connected to the side wall of the support roller, and the cylinder is located on the surface of the two support rollers. Two moving devices are provided on the inner surface of the pad. The moving device includes a moving frame. The surface of the moving frame is slidably connected to the inner wall of the pad. A threaded rod is rotatably connected to the inner surface of the moving frame. A moving block is threadedly connected to the surface of the threaded rod. A sensor is slidably fixedly connected to the side wall of the moving block. A push handle is fixedly connected to the side wall of the moving frame. Pushing the push handle causes the moving frame to move. The moving frame slides on the inner wall of the pad, and the sensor detects the roundness of the cylinder. By setting the moving frame, threaded rod, moving block and push handle, the sensor can be supported, and the position of the sensor can be easily adjusted.

[0006] Preferably, the surface of the movable block is provided with a threaded hole, and the inner wall of the threaded hole of the movable block is threadedly connected to the surface of the threaded rod. When the threaded rod rotates, the threaded rod rotates on the inner wall of the threaded hole. The opening of the threaded hole facilitates the rotation of the threaded rod on the inner wall of the movable block.

[0007] Preferably, the bottom of the mobile frame is rotatably connected to two support wheels. When the mobile frame moves, the mobile frame drives the support wheels to roll on the ground. By setting the support wheels, the mobile frame can be supported.

[0008] Preferably, the side wall of the pad is provided with a sliding groove, and the inner wall of the sliding groove of the pad is slidably connected to the surface of the movable frame. When the movable frame moves, the movable frame slides on the inner wall of the sliding groove. The opening of the sliding groove can facilitate the movement of the movable frame on the inner wall of the pad.

[0009] Preferably, a support rod is fixedly connected to the inner surface of the movable frame, and a sliding hole is provided on the surface of the movable block. The inner wall of the sliding hole of the movable block is slidably connected to the surface of the support rod. When the movable block moves, the movable block slides on the surface of the support rod through the sliding hole.

[0010] Preferably, a protective device is provided on the surface of the movable block near the sensor. The protective device includes a fixed block, the upper surface of which is fixedly connected to the bottom of the movable block. A protective block is rotatably connected to the surface of the fixed block and fits onto the surface of the sensor. A locking block is fixedly connected to the upper surface of the movable block, and an elastic band is fixedly connected to the upper surface of the protective block and fits onto the surface of the locking block. After the sensor is installed, the protective block is pushed to rotate on the surface of the fixed block, and the protective block fits onto the surface of the sensor. By setting the fixed block, protective block, locking block, and elastic band, the sensor can be protected.

[0011] Preferably, a limiting block is fixedly connected to the side wall of the card block. The limiting block is located on the upper surface of the elastic band. When the elastic band moves, the elastic band will pass through the limiting block, and the limiting block can restrict the position of the elastic band.

[0012] The advantages of this utility model are: 1. When the cylinder needs to be tested, the threaded rod is rotated to rotate on the inner surface of the moving frame and the inner wall of the threaded hole of the moving block. The threaded rod drives the moving block to move, and the moving block drives the sensor to move. When the moving block moves, it slides on the surface of the support rod through the sliding hole. After the sensor is adjusted to a suitable height, the drive motor is started to drive the support roller to rotate. The support roller drives the cylinder to rotate, and then the push handle is pushed to drive the moving frame to move. The moving frame slides on the inner wall of the sliding groove on the pad. When the moving frame moves, it drives the sensor to move laterally. The moving frame also drives the support wheel to roll on the ground. By setting the entire device, the sensor can be supported, and the height and lateral position of the sensor can be easily adjusted, thereby reducing the situation where the sensor installation position is not suitable and affects the measurement.

[0013] 2. After the sensor is used up, the present invention pushes the protective block to rotate on the surface of the fixed block, and the protective block is placed on the surface of the sensor. Then, the elastic band is pulled to stretch the elastic band and let it pass through the limiting block. Then the elastic band is released and it will fit against the surface of the card block and the limiting block. By setting the entire device, the sensor can be protected and the accidental contact of the sensor when it is not in use can be reduced. Attached Figure Description

During operation, pushing the threaded rod 52 causes it to rotate on the inner surface of the moving frame 51 and the inner wall of the moving block 53, thereby driving the moving block 53. The sensor 6 moves with the push handle 54. Once the sensor 6 is at a suitable height, the push handle 54 moves the moving frame 51. The moving frame 51 slides on the inner wall of the pad 1. The sensor 6 will detect the roundness of the cylinder 4. By setting the moving frame 51, threaded rod 52, moving block 53 and push handle 54, the sensor 6 can be supported, and the position of the sensor 6 can be easily adjusted.

[0019] The surface of the movable block 53 is provided with a threaded hole 55, and the inner wall of the threaded hole 55 of the movable block 53 is threadedly connected to the surface of the threaded rod 52. During operation, the threaded rod 52 rotates on the inner wall of the threaded hole 55. The opening of the threaded hole 55 facilitates the rotation of the threaded rod 52 on the inner wall of the movable block 53.

[0020] The bottom end of the mobile frame 51 is rotatably connected to two support wheels 56; during operation, the mobile frame 51 drives the support wheels 56 to roll on the ground, and the support wheels 56 can support the mobile frame 51.

[0021] The side wall of the pad 1 is provided with a sliding groove 57, and the inner wall of the sliding groove 57 of the pad 1 is slidably connected to the surface of the movable frame 51. During operation, the movable frame 51 slides on the inner wall of the sliding groove 57. The opening of the sliding groove 57 facilitates the movement of the movable frame 51 on the inner wall of the pad 1.

[0022] The inner surface of the movable frame 51 is fixedly connected to a support rod 58, and the surface of the movable block 53 is provided with a sliding hole 59. The inner wall of the sliding hole 59 of the movable block 53 is slidably connected to the surface of the support rod 58. During operation, the movable block 53 slides on the surface of the support rod 58 through the sliding hole 59.

[0023] A protective device 7 is provided on the surface of the movable block 53 near the sensor 6. The protective device 7 includes a fixed block 71, the upper surface of which is fixedly connected to the bottom of the movable block 53.

[0025] Working principle: When the cylinder 4 needs to be tested, the threaded rod 52 is rotated, causing it to rotate on the inner surface of the moving frame 51 and the inner wall of the threaded hole 55 of the moving block 53. The threaded rod 52 drives the moving block 53 to move, which in turn drives the sensor 6 to move. As the moving block 53 moves, it slides on the surface of the support rod 58 through the sliding hole 59. After the sensor 6 is adjusted to a suitable height, the drive motor 2 is started, causing the support roller 3 to rotate. The support roller 3 drives the cylinder 4 to rotate, and then the push handle 54 is pushed, causing the moving frame 51 to move. The moving frame 51 slides on the inner wall of the sliding groove 57 on the pad 1. As the moving frame 51 moves, it causes the sensor 6 to move laterally. The moving frame 51 also causes the support wheel 56 to roll on the ground. By setting up the entire device, the sensor 6 can be supported, and the height and lateral position of the sensor 6 can be easily adjusted, thereby reducing the impact of mismatched sensor 6 installation position on measurement. After use, push the protective block 72 to rotate it on the surface of the fixed block 71. The protective block 72 will then fit over the surface of the sensor 6. Then pull the elastic band 74 to stretch it and allow it to pass through the limiting block 75. After releasing the elastic band 74, it will adhere to the surfaces of the locking block 73 and the limiting block 75. By setting the entire device, the sensor 6 can be protected, reducing the chance of accidental activation when the sensor 6 is not in use.
