Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a rust removal device for wind turbine towers. Background Technology

[0002] As the core supporting structure of wind turbine generators, the wind turbine tower bears wind loads, its own weight, and environmental corrosion for extended periods. Its surface rust prevention treatment directly affects the equipment's lifespan and safety. During tower manufacturing, processes such as steel plate rolling and welding result in residual oxide scale, welding slag, and rust layers on the surface. Efficient rust removal is necessary during factory processing to meet the adhesion standards of the anti-corrosion coating. Existing automated equipment is mostly designed for standard cylindrical towers, but actual towers often have a tapered shape. CN221020399U discloses a rust removal and grinding device for the outer wall of wind turbine towers. This device clamps and fixes the tower, and a first electric push rod brings the grinding block into contact with the outer wall of the tower. A third motor then rotates a threaded rod, which in turn moves the grinding block horizontally, thus grinding and cleaning the outer wall of the tower. However, since the tower often has a tapered shape, the length of the first electric push rod needs to be repeatedly adjusted during the rust removal process. This causes uneven contact pressure between the grinding block and the tower surface, resulting in over-grinding or under-treatment. In mild cases, the rust removal is not thorough, and in severe cases, the tower body is damaged. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a rust removal device for wind turbine towers, including a base 1. A central fixing seat 2 is fixedly connected to both sides of the top of the base 1, located at the center. Support rods 3 are rotatably connected to both sides of the central fixing seat 2. A connecting rod 4 is rotatably connected to the middle of the support rods 3. A telescopic actuator 5 is fixedly connected between the two connecting rods 4. A roller 6 is provided at one end of each support rod 3. By changing the included angle between the two support rods 3 through the telescopic actuator 5, the height of the roller 6 is changed, thereby enabling the device to handle various rust removal issues. The tapered tower has a base 1 with symmetrically arranged side fixing seats 7 on both sides of the central fixing seat 2. A side fixing seat 20 is fixedly connected to one side of the side fixing seat 7. A connecting rod 28 is rotatably connected to the center of the side fixing seat 7. A roller 29 is arranged on the surface of the connecting rod 28 near its end. A telescopic actuator 21 is rotatably connected between the side fixing seat 210 and one end of the connecting rod 28. By telescopically extending and retracting the telescopic actuator 21, the roller 29 supports the tower from the side, improving the stability of the tower.

[0020] A support column 12 is vertically fixed to one side of the top of the base 1. There are two support columns 12, and a support seat 13 is horizontally fixed to one side. A cleaning frame 14 is slidably connected to the top of the support seat 13. A rust removal roller 15 is rotatably connected inside the cleaning frame 14. The rust removal roller 15 adopts a cylindrical structure and is equipped with a wire brush on its surface. Drive motors 16 that drive the rust removal roller 15 to rotate are set at both ends of the cleaning frame 14. A rotating seat 34 is fixedly connected to one side of the cleaning frame 14. Telescopic actuators 35 are fixedly connected to the surface of the support column 12. The working end of the telescopic actuators 35 is rotatably connected to the rotating seat 34. By adjusting the two telescopic actuators 35, one side of the cleaning frame 14 is parallel to the tower, that is, the surface of the rust removal roller 15 is in uniform contact with the surface of the tower, thereby ensuring that the surface of the tower is subjected to uniform force during grinding and rust removal.

[0021] A tower cylinder 17 is placed on the surface of roller 6 and roller 9. The central axis of the tower cylinder 17 is horizontal. A movable box 18 is slidably connected to the top side of the base 1 and located in the center. A drive device is installed in the movable box 18 to drive the tower cylinder 17 to rotate around its center. The surface of the rust removal roller 15 is in contact with the surface of the tower cylinder 17 and rotates in the same direction. By rotating the rust removal roller 15 and the tower cylinder 17 in the same direction, the relative speed at the contact position between the rust removal roller 15 and the tower cylinder 17 is increased, thereby improving the grinding efficiency.

[0022] The driving device includes a disc 19, a rotating shaft 20, a motor 21, and an adjusting disc 22. The rotating shaft 20 is rotatably connected to a movable box 18. The motor 21 is fixed inside the movable box 18, and one end is fixedly connected to a gear 23. A gear 24, which meshes with the gear 23, is fixedly connected to the surface of the rotating shaft 20. The motor 21 can drive the rotating shaft 20 to rotate through gear transmission. The disc 19 is fixed to one end of the rotating shaft 20 and is coaxial with the rotating shaft 20. An adjusting screw 25 is rotatably connected inside the rotating shaft 20 and is coaxial with the rotating shaft 20. One end of the adjusting screw 25 extends to one side of the disc 19 and is movably connected to the adjusting disc 22. A connecting seat 26, which is movably connected to the adjusting screw 25, is fixedly connected to one side of the adjusting disc 22. The connecting seat 26 has a connecting groove. The cross-section is T-shaped, ensuring the rotation of the adjusting screw 25 and allowing the adjusting disc 22 to move along the length of the adjusting screw 25. A connecting rod 3 27 is rotatably connected to the edge of the disc 19. Multiple connecting rods 3 27 are provided and evenly distributed along the circumference of the disc 19. A support block 28 is rotatably connected to one end of the connecting rod 3 27. A connecting rod 4 29 is rotatably connected between the edge of the adjusting disc 22 and the middle of the connecting rod 3 27. By moving the adjusting disc 22 along the axial direction of the adjusting screw 25, the position of each support block 28 can be adjusted simultaneously, thereby clamping the inner wall of the tower through internal support. Then, the rotation of the disc 19 drives the tower to rotate. In addition, the adjusting screw 25 is used to adjust the position of the adjusting disc 22, avoiding the connection pipes or connecting wires of traditional cylinders or electric cylinders, ensuring the smooth rotation of the disc 19.

[0023] A telescopic rod 30 is fixedly connected between the disc 19 and the adjusting disc 22. The telescopic rod 30 includes an outer cylinder and an inner cylinder. The inner cylinder and the inner wall of the outer cylinder are slidably connected, which improves the stability of the adjusting disc 22. A locking nut 31 is provided on the surface of the adjusting screw 25 to prevent the adjusting screw 25 from loosening. A rubber layer is provided on the surface of the support block 28 to increase the friction between it and the inner wall of the tower.

[0024] The top of the base 1 is provided with a slide rail 32 that is compatible with the movable box 18. The top of the base 1 is also provided with a cylinder 33 that drives the movable box 18 to slide along the slide rail 32. The cylinder 33 lifts the movable box 18 to move to one side of the tower.

[0025] Telescopic actuator 1 5, telescopic actuator 2 11 and telescopic actuator 3 35 are electric push rods, and a control cabinet 36 is set on the top of the base 1 to control the telescopic amount of telescopic actuator 1 5, telescopic actuator 2 11 and telescopic actuator 3 35.

[0026] A movable seat 37 is slidably connected to the top of the base 1 and the side away from the movable box 18. A limiting roller 38 is provided on one side of the movable seat 37. A cylinder 39 is also provided on the top of the base 1 to drive the movable seat 37 to slide. The limiting roller 38 contacts the end of the tower 17 to limit its axial movement. The axial movement of the tower is avoided by the limiting roller 38, which ensures the stability during the rust removal process.

[0027] A vacuum cleaner 40 is also fixedly connected to the top of the base 1. A suction pipe 41 is connected between the inlet end of the vacuum cleaner 40 and the bottom of the cleaning frame 14 to prevent dust from flying during rust removal and protect the site environment.

[0028] Based on the taper of the tower, adjust the telescopic actuator 5 to make the entire tower horizontal after placement. Then, adjust the telescopic actuator 11 to make the roller 9 fit against the surface of the tower. Then, control the cylinder 39 to make the limiting roller 38 contact the end of the tower 17. Control the cylinder 33 to move the moving box 18 to one side of the tower. By rotating the adjusting screw 25, the adjusting plate 22 is moved, so that the inner wall of the tower is fixed by the support block 28. Then, adjust the length of the telescopic actuator 35 to make the surface of the rust removal roller 15 fit against the surface of the tower. Start the drive motor 16 and motor 21 to make the rust removal roller rotate in the same direction as the tower, and finally achieve rust removal.
