[0032] Different from the prior art that uses manual high-altitude operations to clean wind turbine towers, which has technical problems such as low cleaning efficiency, complex operations and potential safety hazards, the present invention provides a vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers, aiming to achieve efficient automatic cleaning and improve the maintenance efficiency of wind farms. The specific structure of the vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers can be found in the following embodiments.

[0033] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of a vehicle-mounted roller brush cleaning device applicable to a wind turbine tower according to an embodiment of the present invention. The vehicle-mounted roller brush cleaning device applicable to a wind turbine tower comprises a vehicle-mounted roller brush cleaning mechanism 100 and a magnetic wall-climbing trolley 200, wherein the magnetic wall-climbing trolley 200 is adsorbed on the tower surface 300, can be stably attached to the vertical surface of the wind turbine tower, and can move autonomously, thereby effectively covering the entire cleaning area. The magnetic wall-climbing trolley 200 can push the vehicle-mounted roller brush cleaning mechanism 100 to clean the tower surface 300 according to a predetermined path.

[0034] Please refer to Figures 2 to 6 , Figure 2 This is a structural schematic diagram of a vehicle-mounted roller brush cleaning mechanism applicable to a wind power tower according to an embodiment of the present invention; Figure 3It is a partial structural schematic diagram of another perspective of a vehicle-mounted roller brush cleaning mechanism applicable to a wind power tower according to an embodiment of the present invention; Figure 4 It is a structural schematic diagram of a roller brush assembly according to an embodiment of the present invention; Figure 5 A structural schematic diagram of a roller brush assembly from another perspective of an embodiment of the present invention; Figure 6 It is a structural schematic diagram of the connection assembly of an embodiment of the present invention. In an embodiment of the present invention, the vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers is installed on a magnetic wall-climbing trolley, and the magnetic wall-climbing trolley is used to adsorb on the surface of the tower, and the vehicle-mounted roller brush cleaning mechanism is used to brush the surface of the tower. The magnetic wall-climbing robot can move freely on the vertical surface, thereby driving the vehicle-mounted roller brush cleaning mechanism to efficiently clean the surface of the tower, and its automated operation greatly improves work efficiency and reduces the need for manual intervention. Using robots for cleaning can not only shorten the construction period, but also effectively reduce operating costs, while avoiding the safety risks brought by high-altitude operations. The vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers includes:

[0035] The transverse synchronous belt module 10 includes a transverse synchronous belt 11 and a first slider 12, wherein the first slider 12 is slidably connected to the transverse synchronous belt 11, the transverse synchronous belt 11 can drive the first slider 12 to move along a first direction, and the transverse synchronous belt 11 is connected to a magnetic wall-climbing trolley;

[0036] The longitudinal synchronous belt module 20 includes a longitudinal synchronous belt 21 and a second slider 22. The second slider 22 is slidably connected to the longitudinal synchronous belt 21. The longitudinal synchronous belt 21 can drive the second slider 22 to move along the second direction. The longitudinal synchronous belt 21 is connected to the first slider 12. The longitudinal synchronous belt 21 can move synchronously with the first slider 12 in the first direction.

[0037] A connecting component 30, one side of which is connected to the second slider 22, and the connecting component 30 can move synchronously with the second slider 22 in the first direction or the second direction;

[0038] The roller brush assembly 40 is connected to the other side of the connecting assembly 30. When the magnetic wall-climbing trolley is adsorbed on the surface of the tower, the roller brush assembly 40 can move in the second direction with the second slider 22 to adjust the distance between the roller brush assembly 40 and the tower surface; the roller brush assembly 40 can move in the first direction with the first slider 12 to increase the brushing area and efficiency of the tower surface.

[0039] Specifically, the transverse synchronous belt 11 module 10 includes a transverse synchronous belt 11 and a first slider 12. The transverse synchronous belt 11 can drive the longitudinal synchronous belt 21 module 20 to move along the first direction through the first slider 12, thereby driving the connecting assembly 30 and the roller brush assembly 40 to move along the first direction. That is, when the magnetic wall-climbing trolley is stationary, the transverse synchronous belt 11 module 10 can control the movement of the first slider 12, which can increase the brushing area of ​​the vehicle-mounted roller brush cleaning mechanism when the magnetic wall-climbing trolley moves according to a single predetermined path, thereby improving the brushing efficiency. The first direction is the left and right direction relative to the tower when the magnetic wall-climbing trolley adsorbs the tower surface. The longitudinal synchronous belt 21 module 20 includes a longitudinal synchronous belt 21 and a second slider 22. The longitudinal synchronous belt 21 can drive the connecting assembly 30 to move along the second direction through the second slider 22, and then drive the roller brush assembly 40 to move along the second direction. In this way, the distance between the vehicle-mounted roller brush cleaning mechanism and the tower surface can be adjusted through the longitudinal synchronous belt 21. The working height of the roller brush assembly 40 can adapt to different towers, so that the distance between the roller brush assembly 40 and the tower surface is kept within a reasonable range to achieve the best cleaning effect. The second direction is the front-to-back direction relative to the tower when the magnetic wall climbing trolley adsorbs the tower surface.

[0040] Please continue to refer to Figure 4 and Figure 5Specifically, the roller brush assembly 40 includes a roller brush box 41, a driving motor 42, a driving wheel 47, a transmission member 43, a driving wheel 44, a roller brush shaft 45 and a roller brush 46. The driving motor 42 is arranged on the roller brush box 41, the roller brush 46 is located in the roller brush box 41 and arranged on the roller brush 46 shaft 45, and the roller brush 46 can partially extend out of the roller brush box 41; the driving wheel 44 is arranged at the end of the roller brush shaft 45, the driving wheel 47 is arranged at one end of the driving shaft of the driving motor 42, the transmission member 43 is wound around the driving wheel 47 and the driving wheel 44, and the driving motor 42 can drive the driving wheel 44 to move through the transmission member 43, thereby driving the roller brush shaft 45 and the roller brush 46 to move. The driving motor 42 is installed on a mounting plate, and the mounting plate is fixed on the roller brush box 41. The driving shaft of the driving motor 42 extends out of the mounting plate 421, and the driving wheel 47 is installed at one end of the driving shaft extending out of the mounting plate 421. In order to protect the driving motor 42, a motor cover 422 is provided outside the driving motor 42. The end of the roller brush shaft 45 exposed from the roller brush box 41 has a bearing cover 451 to protect the bearing. The roller brush box 41 has an opening at one end, and the bristles of the roller brush 46 can be partially exposed from the opening, and a gap is left between the bristles of the roller brush 46 and the inner wall of the roller brush box 41 to avoid collision between the two, which is beneficial to protecting the bristles. When the driving motor 42 is working, it drives the driving wheel 47 to rotate, and then drives the transmission wheel 44 to move through the transmission member 43, and further drives the roller brush shaft 45 to rotate through the transmission wheel 44. Since the roller brush 46 is connected to the roller brush shaft 45, it can drive the roller brush 46 to rotate to complete the cleaning work. The above-mentioned roller brush 46 is placed in the roller brush box 41, which can effectively prevent the dust rolled up by the rotation of the roller brush 46 from splashing outward.

[0041] In a specific embodiment, there are three transmission wheels 44, and the three transmission wheels 44 are all located on one side of the roller brush box 41. The transmission member 43 is sequentially wound around the driving wheel 47 and the three transmission wheels 44. There are two roller brush shafts 45 and roller brushes 46, and the driving motor 42 can drive the two roller brush shafts 45 to rotate through the three transmission wheels 44. In order to improve the cleaning efficiency, there are two roller brush shafts 45 and roller brushes 46, and the two roller brushes 46 are arranged in parallel, which is conducive to increasing the brushing area. When the driving motor 42 rotates, the two roller brushes 46 can be driven to rotate toward the inside of the tower through the transmission member 43, and then the inside of the tower surface can be cleaned, which can bring better cleaning effect. It should be pointed out that in this embodiment, one transmission wheel 44 is only connected to the roller brush shaft 45, and the roller brush shaft 45 is not connected to the roller brush 46, and is only used for transmission. The roller brush shaft 45 is close to the middle roller brush shaft 45.

[0042] In the above embodiment, the transmission member 43 is a transmission belt, and the transmission wheel 44 and the driving wheel 47 are both pulleys. Alternatively, the transmission member 43 is a transmission chain, and the transmission wheel 44 and the driving wheel 47 are both gears.

[0043] Specifically, the bristles of the roller brush 46 are hard bristles, the roller brush 46 has a hollow rubber lining, the roller brush shaft 45 extends into the rubber lining, and the roller brush 46 is fixedly connected to the roller brush shaft 45 by self-tapping screws. The rubber lining is a hollow cylinder. This structure can not only increase the wear resistance of the bristles and improve the cleaning efficiency, but also effectively reduce the damage to the tower surface. When installing the roller brush 46, first put the roller brush 46 into the roller brush box 41, and then extend the roller brush shaft 45 from the hole opened in the side wall of the main body into the hole of the rubber lining, and then use self-tapping screws to drive into the roller brush shaft 45 from the outer wall of the rubber lining, and fix the roller brush shaft 45 to the roller brush 46 to ensure that the roller brush 46 will not fall off during the working process.

[0044] In a specific embodiment, the connection assembly 30 includes a roller brush box 41 supporting a large arm 33 and a connection block 31, the second slider 22 has an installation position 23, one end of the roller brush box 41 supporting a large arm 33 is set at the installation position 23, and the other end is rotatably connected to the connection block 31, and the connection block 31 is connected to the roller brush box 41. The connection block 31 is rotatably connected to the roller brush box 41 supporting large arm 33, and the position of the roller brush box 41 and the tower wall can be adjusted to avoid collision between the roller brush box 41 and the tower wall, so as to adapt to the tower cone surface and ensure the safety and effectiveness of the operation. The connection block 31 can be fixedly connected to the roller brush box 41 by bolts.

[0045] Specifically, the connecting assembly 30 further includes a pin 32, and the roller brush box 41 supports the large arm 33 to be rotatably connected to the connecting block 31 through the pin 32. The pin 32 can make the connecting block 31 perform a small circular motion around the pin 32 to prevent the roller brush box 41 from directly contacting the tower wall.

[0046] Particularly, the roller brush box 41 supports the large arm 33 in an L-shape, which is convenient for structural connection.

[0047] Specifically, a mounting groove 13 is provided on one side of the transverse synchronous belt 11, and the transverse synchronous belt 11 is fixedly connected to the magnetic wall-climbing trolley through the mounting groove 13. The mounting groove 13 can make the installation of the magnetic wall-climbing trolley more stable.

[0048] In summary, the present invention has at least the following advantages:

[0049] 1. The present invention utilizes a robot vehicle to clean the tower instead of manually, thereby improving the efficiency and quality of wind turbine tower cleaning and greatly reducing the cost and risk of manual operation.

[0050] 2. A fully automated control system can be used to clean the tower without supervision. Through advanced sensing technology, image recognition system and control algorithm, precise control of the horizontal and vertical synchronous belts can be achieved, and the distance between the roller brush and the tower surface can be adjusted independently to ensure the best cleaning effect.

[0051] 3. Using a roller brush and dry brush to clean the wind turbine tower can effectively save water resources. This method is particularly suitable for wind turbine towers that are generally located in places with harsh environmental conditions, such as remote mountainous areas or coastal areas, where water sources are scarce or difficult to obtain. The roller brush can effectively remove dust and dirt on the surface of the tower without using water through the principle of physical friction, reducing the dependence on water for cleaning work, while avoiding the burden on the ecological environment, ensuring the cleanliness and normal operation of wind power equipment.

[0052] 4. The design of the roller brush box not only protects the entire cleaning mechanism, but also has a dust suppression function, which can effectively reduce the flying of dust during the cleaning process. This design ensures that during cleaning, dust will not reattach to the surface that has been cleaned, thereby avoiding interference and influence on subsequent cleaning work.

[0053] In an embodiment of the present invention, the vehicle-mounted roller brush cleaning device suitable for wind turbine towers includes a vehicle-mounted roller brush cleaning mechanism and a magnetic wall-climbing trolley, wherein the vehicle-mounted roller brush cleaning mechanism is installed on the magnetic wall-climbing trolley, and the vehicle-mounted roller brush cleaning mechanism includes the above-mentioned vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers. The specific structure of the vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers please refer to the above-mentioned embodiment, which will not be repeated here. Since the vehicle-mounted roller brush cleaning device suitable for wind turbine towers of this scheme applies the above-mentioned vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers, it has all the advantages and effects of the vehicle-mounted roller brush cleaning mechanism suitable for wind turbine towers.

[0054] It can be pointed out that the above-mentioned vehicle-mounted roller brush cleaning device for wind turbine towers can not only improve the cleaning quality, but also add a monitoring module to realize data collection and monitoring, provide real-time feedback, and provide an important basis for subsequent maintenance decisions. The vehicle-mounted roller brush cleaning mechanism can be combined with an intelligent control system, which can automatically adjust the cleaning intensity and speed according to the actual situation on site, ensuring the cleaning effect while reducing potential damage to the tower structure. This intelligent cleaning method not only significantly improves the cleaning efficiency of wind farms, but also greatly reduces the cost of manual cleaning. Ultimately, it ensures the efficient and safe operation of wind power stations and lays a solid foundation for the sustainable development of renewable energy.
