[0041] In the prior art, the cleaning of wind power tower barrels mainly relies on wall-climbing robots. These robots can move along the wall surface of the wind power tower barrel and clean its surface through cleaning devices such as brush disks. In the single cleaning process of the existing wind power tower barrel wall-climbing robots, as the cleaning time increases, the cleaning area continuously expands, and the brush disks will gradually become dirty, resulting in a significant decline in the cleaning effect.

[0042] In the embodiment of the present application, the rotation mechanism drives the connection component to rotate, replacing the dirty brush disk with a new one, thereby improving the cleaning effect of the wall surface. The following will further illustrate this embodiment with reference to the accompanying drawings.

[0043] Among them, Figure 1 is a schematic structural diagram of the wall surface cleaning device provided by the embodiment of the present application. Figure 2 is Figure 1 a schematic structural diagram of the rotation mechanism in Figure 3 is Figure 1 an enlarged view of part A in Figure 4 is a side view of the wall surface cleaning device provided by the embodiment of the present application. Figure 5 is Figure 1 an enlarged view of part B in Figure 6 is a top view of the wall surface cleaning device provided by the embodiment of the present application.

[0044] As Figure 1 shown, the embodiment of the present application provides a wall surface cleaning device, including a housing 100, a rotation mechanism 200, and a cleaning mechanism 300. The cleaning mechanism 300 includes a connection component 310, a driving component 320, and at least two brush disks 330.

[0045] The rotation mechanism 200 is arranged inside the housing 100, and the rotation mechanism 200 is used to connect with the connection component 310.

[0046] The connection component 310 is used to connect with all the brush disks 330. One group of brush disks 330 abuts against the wall surface. The driving component 320 is arranged on the connection component 310 and is used to drive the brush disks 330 to rotate.

[0047] When one group of brush disks 330 works for a preset time, the rotation mechanism 200 drives the connection component 310 to rotate, so that the next group of brush disks 330 abuts against the wall surface.

[0048] When cleaning the wall surface, the rotation mechanism 200 drives the connection component 310 to rotate, replacing the dirty brush disks 330 with new ones, thereby improving the cleaning effect of the wall surface.

[0049] Among them, the housing 100 in this embodiment is square or rectangular, with an opening provided on one side. The brush disk 330 extends 5 - 10 centimeters outside the housing 100 from the opening. Multiple cleaning mechanisms 300 are provided on the rotating mechanism 200. The shape of the brush disk 330 is circular, and bristles are evenly distributed on the front side of the brush disk 330. The bristles can be hard bristles and soft bristles, and users can select different bristle combinations according to needs, so as to achieve various cleaning functions.

[0050] The sum of the diameters of multiple brush disks 330 is the same as the width of the housing 100. Defining the width can ensure that the device can completely clean the area of the bottom wall surface, improving the cleaning effect.

[0051] Among them, multiple brush disks 330 are arranged around the connecting component 310, and the position of the brush disk 330 is changed by rotating the connecting component 310.

[0052] Exemplarily, if two brush disks 330 are provided, the two brush disks 330 are located on opposite sides of the connecting component 310. If three brush disks 330 are provided, the three brush disks 330 are arranged in a triangle. If four brush disks 330 are provided, the four brush disks 330 are arranged in a cross.

[0053] As Figure 2 shown, in the embodiment of the present application, the rotating mechanism 200 includes a first driving motor 210 and a rotating rod 220. The first driving motor 210 is arranged on the inner side wall of the housing 100, and the first driving motor 210 is used to connect with the rotating rod 220.

[0054] Among them, the rotating rod 220 is horizontally arranged in the housing 100. One end of the rotating rod 220 is connected to the output shaft of the first driving motor 210, and the other end is rotatably connected to the other inner side wall through a rotating seat.

[0055] As Figure 6 shown, exemplarily, the lengths of the rotating rods 220 increase in sequence from the middle to both sides. Setting different lengths of the rotating rods 220 facilitates the brush disks 330 in the device to fit the arc surface of the wind turbine tower wall, improving the cleaning effect.

[0056] Exemplarily, on the basis of the above wall surface cleaning device, it further includes an angle adjustment rotating mechanism 200. This mechanism includes an angle sensor and an angle adjuster. The angle sensor is used to detect the rotation angle of the rotating rod 220, and the angle adjuster is used to adjust the rotation angle of the rotating rod 220 according to the detection result. This can ensure that the brush disk 330 always maintains the best contact angle with the wall surface, improving the cleaning effect.

[0057] Exemplarily, on the basis of the above-mentioned wall cleaning device, a wireless control rotation mechanism 200 is further included. This mechanism includes a wireless receiving module and a control module. Users can send control instructions through a mobile device, and after the control module receives the instructions, it controls the start, stop, and speed adjustment of the first driving motor 210. In this way, remote control can be achieved, improving the convenience of operation.

[0058] On the basis of the above-mentioned wall cleaning device, a dual-driving motor system is further included. Two first driving motors 210 are provided. The second driving motor 321 is arranged on the other side wall of the housing 100 and is connected to the other end of the rotating rod 220. The dual-driving motor system can provide stronger power and a more stable rotation effect, and is particularly suitable for the situation where there are more brush discs 330 and a single motor cannot drive them.

[0059] Combined with Figure 2 As shown, in the embodiment of the present application, the connection assembly 310 includes a T-shaped tube 311 and a connecting straight tube 312. The T-shaped tube 311 is arranged on the rotating rod 220, and the connecting straight tube 312 is rotatably arranged in the T-shaped tube 311. Both ends of the connecting straight tube 312 are respectively connected with a brush disc 330.

[0060] The driving assembly 320 is arranged on the T-shaped tube 311. The driving assembly 320 is used to connect with the connecting straight tube 312 and drive the connecting straight tube 312 to rotate in the T-shaped tube 311, so as to drive the brush disc 330 on the connecting straight tube 312 to rotate.

[0061] Among them, the bottom of the T-shaped tube 311 is fixedly connected to the rotating rod 220. Both ends of the top of the T-shaped tube 311 are respectively connected with two brush discs 330. When it is necessary to switch the brush disc 330, rotate the T-shaped tube 311 by 180 degrees to extend the other brush disc 330 out of the opening.

[0062] Exemplarily, the T-shaped tube 311 can also be a cross-shaped tube. Two mutually perpendicular connecting straight tubes 312 are arranged in the cross-shaped tube. Both ends of the two connecting straight tubes 312 are respectively connected with brush discs 330. Four driving assemblies 320 are arranged on the cross-shaped tube to drive the corresponding brush discs 330 to rotate. When it is necessary to switch the brush disc 330, rotate the cross-shaped tube by 90 degrees to extend the other brush disc 330 out of the opening.

[0063] Combined with Figure 5 and Figure 6 As shown, in the embodiment of the present application, the driving assembly 320 includes a second driving motor 321, a driving wheel 322, a driven wheel 323, and a transmission belt 324.

[0064] The second drive motor 321 is arranged on the T-shaped pipe 311. The second drive motor 321 is connected to the driving wheel 322. The connecting straight pipe 312 is connected to the driven wheel 323. The driving wheel 322 and the driven wheel 323 are connected by a transmission belt 324.

[0065] Among them, the second drive motor 321 is arranged on the top of the T-shaped pipe 311. The driving shaft of the second drive motor 321 is connected to the driving wheel 322. The driven wheel 323 is sleeved on the connecting straight pipe 312, and the driven wheel 323 is located at the bottom of the driving wheel 322. When the second drive motor 321 rotates, it drives the driving wheel 322 to rotate. The driving wheel 322 drives the driven wheel 323 to rotate through the transmission belt 324. The driven wheel 323 drives the connecting straight pipe 312 to rotate, thereby driving the brush disc 330 to rotate to achieve the cleaning of the wall surface.

[0066] In the embodiment of the present application, a moving mechanism 400 is further included. The moving mechanism 400 is arranged on opposite sides of the housing 100. The housing 100 moves along the wall surface through the moving mechanism 400.

[0067] In the embodiment of the present application, the moving mechanism 400 can drive the housing 100 to move vertically along the tower wall of the wind power tower to achieve the cleaning of the wind power tower.

[0068] In the embodiment of the present application, the moving mechanism 400 includes a towing rope, a towing plate 410 and a moving component 420. The towing plate 410 and the moving component 420 are both arranged on the housing 100. The housing 100 is connected to the wall surface through the moving component 420. The towing rope is connected to the towing plate 410. The towing rope drives the housing 100 to move along the wall surface by pulling the towing plate 410.

[0069] Among them, when cleaning, a pulley needs to be arranged at the top of the wind power tower and a winch is arranged on the ground. The towing rope is sequentially connected to the winch, the pulley and the towing plate 410. The winch winds and unwinds the towing rope to lift and lower the housing 100.

[0070] Among them, at least two towing plates 410 are arranged on the side wall of the same side of the housing 100. Through holes are arranged on the towing plate 410. The fixing between the towing rope and the towing plate 410 is realized through a knot on the towing rope that is larger than the aperture of the through hole.

[0071] Among them, at least two moving components 420 are arranged on the side wall of the same side of the housing 100.

[0072] Combined with Figure 3 and Figure 4 , in the embodiment of the present application, the moving component 420 includes a first connecting plate 421, a hydraulic cylinder 422, a second connecting plate 423 and a moving wheel 424.

[0073] The first connecting plate 421 is arranged on the housing 100, the hydraulic cylinder 422 is arranged on the first connecting plate 421, the output shaft of the hydraulic cylinder 422 is connected to the second connecting plate 423, the moving wheel 424 is arranged at one end of the second connecting plate 423 away from the hydraulic cylinder 422, and the hydraulic cylinder 422 is used to drive the moving wheel 424 to abut against the wall surface.

[0074] Among them, the first connecting plate 421 is used to fix the hydraulic cylinder 422. By abutting the moving wheel 424 against the wall surface, the housing 100 can move more smoothly on the wall surface.

[0075] In the embodiment of the present application, a chute 110 is further arranged on the housing 100, the second connecting plate 423 is slidably arranged in the chute 110, and the sliding direction of the second connecting plate 423 in the chute 110 is perpendicular to the wall surface.

[0076] Among them, the chute 110 is used to limit the moving direction of the second connecting plate 423 to prevent the hydraulic cylinder 422 from bending under the action of gravity, thereby affecting the abutting effect between the moving wheel 424 and the wall surface.

[0077] In the embodiment of the present application, the moving assembly 420 further includes a magnet block 425, and the magnet block 425 is arranged on the housing 100.

[0078] Among them, the wall surface of the wind turbine tower is made of iron material. The magnet block 425 is used to avoid generating a force so that the housing 100 can be adsorbed on the wall surface to ensure the cleaning effect of the brush disc 330 and avoid the housing 100 from falling.

[0079] In the embodiment of the present application, a water spraying assembly 500 is further included. The water spraying assembly 500 is arranged on the housing 100, the water spraying assembly 500 is arranged above the cleaning mechanism 300, and the water spraying assembly 500 is used to spray water on the wall surface.

[0080] Exemplarily, the water spraying assembly 500 includes structures such as a water tank, a water pump and a nozzle, and is used to spray a cleaning liquid to improve the cleaning effect.

[0081] It should be noted that components such as the hydraulic cylinder 422 and the drive motor in the present application can all be remotely controlled by a controller. Since remotely controlling components such as the drive motor and the hydraulic cylinder 422 belongs to the prior art, the present application will not elaborate. At the same time, in order to ensure the normal operation of each electrical component, a power supply connected to each component is also arranged in the housing 100.

[0082] The process of the wall cleaning device proposed in the embodiment of the present application for cleaning the wind power tower wall is as follows: First, move the housing 100 close to the wind turbine tower wall and adsorb it through the magnet block 425. Control the hydraulic cylinder 422 to drive the moving wheels 424 on the second connecting plate 423 to abut against the wind turbine tower wall surface. Then, drive the traction rope to move through the winch, so that the whole device rises to be close to the cleaning area. Control the water spraying assembly 500 to work through the controller, spray cleaning liquid and water on the wind turbine tower wall surface. Then, control the second driving motor 321 to work through the controller, and drive the connecting straight pipe 312 and the brush disc 330 to rotate through the cooperation of the driving wheel 322, the driven wheel 323 and the transmission belt 324 to clean the wind turbine tower wall surface. After a period of time, control the hydraulic cylinder 422 to work through the controller, drive the moving wheels 424 to further press the wind turbine tower wall surface to increase the distance between the brush disc 330 close to the wind turbine tower wall surface and it. Then, control the first driving motor 210 to work through the controller, drive the rotating rod 220 to drive the plurality of T-shaped pipes 311 and the brush disc 330 to rotate 180 degrees, so that the other side brush disc 330 is close to the wind turbine tower wall surface, and repeat the above cleaning actions to complete the cleaning. Therefore, by driving the connecting assembly 310 to rotate through the rotating mechanism 200, the dirty brush disc 330 is replaced with a new brush disc 330, greatly improving the cleaning effect of the wall surface.
