[0016] Embodiment 1 like Figures 1 to 3 As shown, the present invention provides a wind turbine tower cleaning mechanism, which has waterproof and anti-corrosion properties, can adapt to different climatic conditions, and ensure cleaning efficiency and safety. Specifically, it includes a mobile vehicle 1, and climbing wheels 101 are installed on both sides of the mobile vehicle 1 to facilitate the mobile vehicle 1 to climb the wind turbine tower for convenient cleaning.

[0017] A mobile platform 2 is provided on one side of the mobile vehicle 1, and a protective device is provided on the outside of the mobile platform 2. The mobile platform 2 includes a slide rail 202, which makes the cleaning process more stable and prevents poor cleaning effect caused by tilting or vibration. At the same time, the protective device can protect the mobile platform 2 to ensure safety during high-altitude operations. Limiters 203 are provided at both ends of the slide rail 202, and the limiters 203 can ensure that the travel of the slider 204 on the slide rail 202 during the operation is controllable, greatly improving the safety of high-altitude operations.

[0018] A sliding motor 201 is provided on one side of the slide rail 202, and the sliding motor 201 is located on one side of a limiter 203. A slider 204 is provided on the slide rail 202, and the sliding motor 201 can realize the horizontal movement of the slider 204. A rotating slide 205 is installed on the slider 204, and a rotating motor 206 is installed on one side of the rotating slide 205. The rotating motor 206 is connected to the rotating slide 205 using a transmission structure in the prior art. The rotating motor 206 can change the rotation angle of the rotating slide 205, and can flexibly respond to changes in the shape of the tower, thereby improving the cleaning efficiency and adaptability. A cleaning module 3 is installed on the side of the rotating slide 205 opposite to the slider 204. Changing the rotation angle of the rotating slide 205 can adjust the inclination angle of the cleaning module 3, ensuring that the cleaning module 3 can work at different heights and inclination angles.

[0019] A sensor assembly 207 is installed at the bottom of the slider 204. The sensor assembly 207 includes a sensing camera and a sensor. The sensing camera and the sensor can sense the angle between the tower and the slider 204, thereby changing the inclination angle of the cleaning module 3 in real time, making cleaning more stable and efficient. The sensor can monitor the dirt situation and automatically adjust the cleaning parameters such as water pressure and brush plate 309 speed according to feedback to ensure the best cleaning effect.

[0020] The cleaning module 3 adopts a modular design, which is convenient for maintenance and replacement. The user can quickly disassemble and replace the cleaning module 3 according to the actual situation, saving time and reducing maintenance costs. The cleaning module 3 includes a cleaning bracket 301, and a reduction motor 302 is provided at the bottom of the cleaning bracket 301. The cleaning bracket 301 provides support for the reduction motor 302. The reduction motor 302 is connected to the first pulley 303, and the first pulley 303 is connected to the second pulley 305 through the belt 304. The second pulley 305 is connected to the transmission shaft 306. The reduction motor 302 drives the first pulley 303 to rotate, and the first pulley 303 drives the second pulley 305 to rotate through the belt 304, so that the transmission shaft 306 rotates.

[0021] A brush plate 309 is provided at the bottom of the transmission shaft 306, and a brush 310 is installed at the bottom of the brush plate 309. The rotation of the transmission shaft 306 drives the brush plate 309 to rotate, so that the brush 310 fits closely with the surface of the wind turbine tower, cleans the surface of the wind turbine tower, effectively removes dirt and dust on the surface of the wind turbine tower, and reduces damage to the tower surface, ensuring the best cleaning effect.

[0022] The middle part of the transmission shaft 306 is connected to the tension bracket 311 through the bearing 308, so that the tension bracket 311 can support the transmission shaft 306 without hindering the rotation of the transmission shaft 306. A hole retaining spring 307 is installed on the transmission shaft 306 above the bearing 308, and the hole retaining spring 307 can effectively prevent the bearing 308 from moving in the axial direction and perform precise positioning. The tension bracket 311 is connected to the cleaning bracket 301 by bolts, which is convenient for maintenance and replacement, saving maintenance time and cost.

[0023] The mobile vehicle 1, the mobile platform 2 and the cleaning module 3 are all connected to the intelligent control system. The data detected by the sensing camera and the sensor will be transmitted to the intelligent control system for analysis. The information fed back after the analysis by the intelligent control system will control the operation of the mobile vehicle 1, the mobile platform 2 and the cleaning module 3.

[0024] When a wind turbine tower cleaning mechanism provided by the present invention is used, the intelligent control system controls the mobile vehicle 1 to move to a suitable position, and then starts the reduction motor 302, so that the brush plate 309 rotates to clean the surface of the wind turbine tower. The sliding motor 201 is started to drive the slider 204 to move, so that the brush plate 309 cleans different positions. When the sensing camera and the sensor detect the angle between the surface of the wind turbine tower and the slider 204, it is transmitted to the intelligent control system, and the intelligent control system controls the rotating motor 206 to drive the rotating slide 205 to rotate, thereby changing the rotation angle of the brush plate 309. When the sensing camera and the sensor detect that the dirt on the surface of the wind turbine tower has not been removed, the information will be transmitted to the intelligent control system, and the clear parameters will be automatically adjusted according to the information fed back by the intelligent control system to ensure the best cleaning effect.

[0025] Therefore, the present invention adopts the above-mentioned wind turbine tower cleaning mechanism, the cleaning module adopts a modular design to facilitate maintenance and replacement, and an induction camera and a sensor are provided to ensure the safety and accuracy of the cleaning work. The mobile platform adopts a slide rail to facilitate the horizontal movement of the cleaning module to make the cleaning process more stable and prevent poor cleaning effect due to vibration or tilt. A rotating slide is provided to facilitate the cleaning module to adjust the inclination angle along the curvature of the tower.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
