Description

Technical Field

[0001] This utility model belongs to the field of wind turbine tower technology, and specifically relates to a wind turbine tower surface cleaning device. Background Technology

[0002] As a core component of wind power generation equipment, the wind turbine tower bears the load for the normal operation of the wind turbine generator and its rotating blades. Because wind power equipment is typically installed in remote areas such as ridges and mountaintops, the outer surface of the tower accumulates a large amount of dirt, dust, and oil over long periods of operation. Currently, the cleaning of wind turbine towers still largely relies on manual labor. Manual cleaning not only carries high safety risks but also requires operation under low wind speed conditions, increasing the difficulty and cost of the cleaning work. Furthermore, since wind turbine towers are typically tens of meters high, manual cleaning requires a significant amount of time and effort, easily leading to worker fatigue and low work efficiency.

[0003] In existing technologies, methods for cleaning the surface of wind turbine towers are relatively traditional. For example, patent CN220444481U provides a wind turbine tower surface cleaning device, including components such as a base ring, a connecting ring, and a cleaning unit. This device can clean the surface of the wind turbine tower through the reciprocating motion of the cleaning unit, the spraying of cleaning agent by nozzles, and the action of the wiping unit. Specifically, this device uses a base ring fitted onto the outer surface of the tower for cleaning operations and is hoisted by a winch and connecting ring, avoiding the influence of weather factors and improving cleaning efficiency.

[0004] However, existing technologies still have some shortcomings. First, while current devices can achieve surface cleaning, the cleaning process remains relatively complex, requires manual operation, and carries certain safety risks. Second, during the cleaning process, residual stains or cleaning agents may cause secondary contamination of the tower surface. Therefore, how to further improve the cleaning effect and reduce operational risks remains a problem that needs to be solved.

[0005] Therefore, how to improve the efficiency and quality of wind turbine tower surface cleaning while ensuring safety, and avoid secondary pollution to the environment or the tower, has become an urgent technical challenge. Utility Model Content

Figure 1 ,refer to Figure 1 and Figure 3 The wind turbine tower surface cleaning device includes: a connecting ring 1, which has a hollow inner cavity. A ring groove 2 is coaxially formed on the inner wall of the connecting ring 1. A ring body 3 is rotatably sleeved in the ring groove 2, so that the ring body 3 can rotate axially within the ring groove 2. A number of bristles 4 are arranged in a circular array on the side wall of the ring body 3 facing the hollow inner cavity. A drive assembly 5 is provided on the side wall of the connecting ring 1. The output end of the drive assembly 5 is connected to the ring body 3. The drive assembly 5 drives the ring body 3 to rotate axially, thereby driving the number of bristles 4 to perform preliminary cleaning on the surface of the wind turbine tower.

[0024] One end of the connecting ring 1 is coaxially connected to the first conveying pipe 6, the second support bar 7, and the second conveying pipe 8 in sequence, and both the first conveying pipe 6 and the second conveying pipe 8 have external end pipes 11 on their side walls; Figure 3In the example shown, the second delivery pipe 8, the second support bar 7, the first delivery pipe 6, and the connecting ring 1 are arranged vertically; the first delivery pipe 6 has a plurality of first spray heads 9 arranged in a circular array on the side wall facing the hollow inner cavity, and the second delivery pipe 8 has a plurality of second spray heads 10 arranged in a circular array on the side wall facing the hollow inner cavity, and both the first delivery pipe 6 and the second delivery pipe 8 have external end pipes 11 on their side walls.

[0028] During the cleaning operation of the wind turbine tower surface, the spectral camera 12 takes real-time pictures of the pipe wall to collect the stain image information of the pipe wall; when a large area of ​​stains is captured, the output power of the drive component 5 is adjusted accordingly, the rotation speed of the ring component 3 is increased, and the liquid output of the first spray head 9 and the second spray head 10 is increased at the same time to improve the cleaning effect.

[0029] Correspondingly, the ultrasonic sensor 13 is used to monitor the cracks in the pipe wall and send the collected information to the terminal for subsequent repair and maintenance, thereby achieving the purpose of intelligent adjustment and protection.

At the same time, cleaning agent is sprayed onto the surface of the wind turbine tower by the first spray head 9, and clean water is sprayed onto the surface of the wind turbine tower by the second spray head 10. During the ascent of the cleaning device, the tower surface is first wetted with clean water to rinse off some stains, and then the remaining stains are cleaned by the ring component 3 on top of the cleaning agent. Simultaneously, the spectral camera 12 collects image data of the tower surface, and then adjusts the flow regulating valve 1102 and the rotation speed of the ring component 3 accordingly to meet the cleaning intensity under different stain conditions, improving cleaning efficiency while reducing damage to the tower surface.

[0040] During the descent of the cleaning device in this application, the surface of the tower is rinsed with clean water to remove residual stains and cleaning agents, ensuring the cleanliness of the tower surface and achieving the purpose of intelligent adjustment and cleaning.
