Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and specifically relates to a cleaning system for wind power generation devices. Background Technology

[0002] The tower is one of the most crucial core components of a wind turbine generator. Being exposed to the outdoors for extended periods, its surface easily accumulates pollutants, leading to corrosion and structural damage. If left uncleaned, these pollutants can react chemically with the tower material, gradually eroding the protective coating and even penetrating deep into the structure, resulting in a decrease in tower strength. Currently, cleaning is typically done manually, but due to the tower's height, manual cleaning is labor-intensive, dangerous, and inefficient. Utility Model Content

[0021] The climbing mechanism 1 can be a magnetic wall-climbing robot or a vacuum adsorption wall-climbing robot. In this embodiment, a vacuum adsorption wall-climbing robot is used.

[0022] refer to Figure 2 As shown, the vacuum suction wall-climbing robot includes a first mounting frame 11, a second mounting frame 12, a moving cylinder 13, and a vacuum generator 14. The first mounting frame 11 has first vacuum suction cups 16 at both ends and a guide seat 15 in the middle. The second mounting frame 12 is slidably engaged with the guide seat 15, and the second mounting frame 12 and the first mounting frame 11 form a cross-shaped structure. The moving cylinder 13 is located at one end of the second mounting frame 12, and the extension and retraction direction of the moving cylinder 13 is consistent with the length direction of the second mounting frame 12.

The vacuum generator 14 is located on the first mounting frame 11, and the first vacuum suction cups 16 and the second vacuum suction cups 17 are connected to the vacuum generator 14 through air pipes.

[0023] The circumferential moving mechanism 2 includes a rack 21, a gear 22, a moving base 23, and a first motor 24. (Reference) Figure 3 As shown, the rack 21 has an arc-shaped structure. The rack 21 is supported on the first mounting frame 11 or the second mounting frame 12 of the climbing mechanism 1 by a bracket. The rack 21 is detachably connected to the bracket, which facilitates the disassembly and replacement of the rack 21. The movable seat 23 is connected to the rack 21 and slides in engagement. The first motor 24 is mounted on the movable seat 23. The gear 22 is mounted on the output shaft of the first motor 24 and can rotate synchronously. The gear 22 also meshes with the rack 21. In this way, when the first motor 24 is working, it can drive the movable seat 23 to move on the rack 21.

[0024] The cleaning mechanism 3 includes a robotic arm 31, a second motor 32, and a cleaning brush 33. One end of the robotic arm 31 is fixed on the movable base 23, the second motor 32 is located at the other end of the robotic arm 31, and the cleaning brush 33 is located on the output shaft of the second motor 32.

[0025] The system also includes a water supply component 4, which includes a water tank 41, a water supply pipe 43, and a nozzle 42. The water tank 41 is used to hold clean water or cleaning solution and is equipped with a water pump. The nozzle 42 is supported on a movable base 23. One end of the water supply pipe 43 is connected to the nozzle 42, and the other end is connected to the water pump in the water tank 41. The water pump can deliver the water in the water tank 41 to the nozzle 42 through the water supply pipe 43 and spray it out from the nozzle 42. The nozzle 42 sprays in the direction of the cleaning brush 33, thus providing the cleaning effect of the cleaning brush 33.

[0026] The system also includes a wastewater recovery component 5, which includes a baffle plate 51, a wastewater storage tank 52, a wastewater recovery pipe 53, and a wastewater storage tank 54. The baffle plate 51 can be made of rubber material. The baffle plate 51 is supported on the movable seat 23 by a connecting rod and is located below the cleaning brush 33. The baffle plate 51 is inclined. A recovery funnel is provided at the lower end of the baffle plate 51. The lower end of the recovery funnel is connected to the wastewater storage tank 52 through a guide pipe. The wastewater storage tank 52 is also connected to the vacuum generator 14 through an air pipe. One end of the wastewater recovery pipe 53 is connected to the wastewater storage tank 52, and the other end is inserted into the wastewater storage tank 54.

[0027] The working principle of the wind power generation device cleaning system provided in this embodiment of the utility model is as follows: When cleaning the wind turbine tower is required, the climbing mechanism 1 is attached to the outer wall of the tower via the first vacuum suction cup 16 and the second vacuum suction cup 17. The second mounting bracket 12 faces vertically, and the water tank 41 and the wastewater storage tank 54 are placed on the ground. During cleaning, the second motor 32 drives the cleaning brush 33 to clean the outer wall of the tower. At the same time, the water pump delivers clean water or cleaning solution from the water tank 41 to the nozzle 42 through the water supply pipe 43, and sprays it from the nozzle 42 onto the area cleaned by the cleaning brush 33. Then, the first motor 24 drives the moving base 23 to move on the rack 21. The curvature of the rack 21 is consistent with the circumferential curvature of the tower, thereby driving the tower to move. The cleaning brush 33 moves along the circumference of the tower and cleans it. The baffle plate 51 is located below the cleaning brush 33 and abuts against the outer surface of the tower. In this way, the wastewater generated during cleaning will flow downwards onto the baffle plate 51 and flow along the baffle plate 51 towards its lower end. The vacuum generator 14 works to draw the wastewater from the recovery funnel of the baffle plate 51 into the wastewater storage tank 52. Then, the wastewater in the wastewater storage tank 52 flows through the wastewater recovery pipe 53 into the wastewater storage tank 54 placed on the ground. Since the tower is cleaned from bottom to top, the wastewater recovery component 5 reduces the possibility of contamination of the cleaned parts below.

[0028] After cleaning the area corresponding to rack 21 at the same height, the second vacuum suction cup 17 is released, and then the telescopic rod of the moving cylinder 13 extends to drive the second mounting bracket 12 to move upward. After moving into position, the second vacuum suction cup 17 is attached to the outer wall of the tower. At the same time, the first vacuum suction cup 16 is released, and the telescopic rod retracts to drive the first mounting bracket 11 to move upward. After moving into position, the first vacuum suction cup 16 is also attached to the outer wall of the tower, thus completing one step movement.

[0029] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
