For example, Chinese patent publication number CN221060578U discloses a robot for cleaning building exterior walls. The robot uses a spring to elastically support the cleaning brush, allowing the brush to elastically contact the wall for easier cleaning. However, as the brush wears and the spring stretches, the brush's cleaning power weakens. Especially when the wall surface is uneven, incomplete cleaning may occur.

[0025] An anti-residue component 4 is arranged on the side of the cleaning component 3 away from the wall, and the anti-residue component 4 is used to adjust the distance between the cleaning component 3 and the wall to avoid incomplete cleaning of stains;

[0026] Detection devices (not shown in the figures) are arranged at the upper and lower ends of the cleaning component 3 for real-time monitoring of the cleaning quality.

[0027] Among them, the rope is detachably connected to the tractor 2 for convenient storage of the device.

[0028] During use, place the winding mechanism 1 at the top edge position of the building to be cleaned, place the tractor 2 on the outer wall of the ground floor, then control the winding mechanism 1 to release the rope to the tractor 2, install the cleaning assembly 3 on the rope, and fix the end of the rope to the tractor 2. Then control the cleaning assembly 3 to move along the rope to gradually clean the wall. At the same time, the wall being cleaned can be detected in real time according to the detection device. When the cleaning is not thorough, the control device moves to this area, and the distance between the cleaning assembly 3 and the wall is changed through the anti-residue assembly 4 to increase the cleaning intensity and improve the cleaning effect, avoiding incomplete cleaning caused by uneven walls.

[0029] Specifically, the winding mechanism 1 is a winch, and the detection device is a micro probe, which can wirelessly transmit the captured image to the manual operation terminal through the control unit, and remotely judge the cleaning quality manually to ensure the cleaning quality.

[0030] In this embodiment, the cleaning assembly 3 includes: a substrate 31, a sliding cavity 311 is opened in the middle of the side of the substrate 31 facing away from the wall, a connecting block 32 is elastically slidably arranged in the sliding cavity 311, and a water tank 34 is fixedly sleeved on the outer peripheral side of the substrate 31;

[0031] A limiting hole is penetrated through the side surface of the connecting block 32 corresponding to the rope, and the limiting hole is consistent with the extending direction of the rope;

[0032] A cleaning mechanism 33 is installed in the middle of the side of the substrate 31 facing the wall;

[0034] It should be explained that a pressure sensing unit is arranged in the elastic telescopic member 35, and the distance between the cleaning assembly 3 and the wall surface is judged by changing the value of the pressure detection unit to ensure effective cleaning. Among them, the elastic telescopic member 35 is an elastic telescopic tube or an elastic telescopic rod, and the ball 36 at its end is in rolling contact with the wall surface to avoid sliding friction between the device and the wall surface, causing damage to the device or the wall surface.

[0035] In this embodiment, the cleaning mechanism 33 includes: a fixed frame 331, the fixed frame 331 is fixedly arranged on the side of the substrate 31 close to the wall, an opening is arranged at the lower end of the fixed frame 331, a cleaning cylinder 332 is rotatably arranged perpendicular to the rope in the fixed frame 331, a plurality of cleaning cylinders 332 are arranged at intervals along the rope direction, the cleaning cylinders 332 are synchronously driven by an external drive source, and a cleaning sleeve is fixedly sleeved on the outer side of the cleaning cylinder 332 for cleaning the wall.

[0036] Preferably, cleaning brushes or cleaning cotton are provided on the surface of the cleaning sleeve.

[0037] In this embodiment, the rope includes a main rope 11 and two groups of auxiliary ropes 12. The auxiliary ropes 12 are symmetrically arranged on both sides of the main rope 11 and are used to guide the cleaning assembly 3. By arranging the auxiliary ropes 12 for guiding the device, it is avoided that the device tilts during the cleaning process, affecting the cleaning effect.

[0038] In this embodiment, a driving cavity 321 is formed in the inner top of the connecting block 32 corresponding to the limiting hole of the main rope. A plurality of driving wheels 322 are rotatably arranged at intervals on both sides of the main rope 11 in the driving cavity 321. The wheel surface of the driving wheel 322 is made of a flexible material. The wheel surface of the driving wheel 322 is of an inwardly concave U-shaped or V-shaped structure. The driving wheel 322 is elastically abutted against the rope, and the driving wheel 322 is synchronously driven by an external motor.

[0039] Specifically, the external motor is installed outside the connecting block 32. When the cleaning assembly 3 moves, the external motor drives the driving wheel 322 to rotate. By using the frictional force between the wheel surface of the driving wheel 322 and the main rope 11, the cleaning assembly 3 moves along the main rope to clean the wall.

[0040] In this embodiment, a plurality of springs 323 are evenly distributed at the bottom of the connecting block 32. The connecting block 32 is elastically connected to the bottom of the sliding cavity 311 through the springs 323.

The protective frame 44 is fixedly connected to the U-shaped frame 41 through a plurality of connecting rods.

[0042] Specifically, the rotating drive mechanism 42 is a motor. By driving the fan blade 43 to rotate at different speeds by the rotating drive mechanism 42, different magnitudes of thrust are generated, so that the spring 323 is stretched, and further the distance between the cleaning assembly 3 and the wall is changed to realize the cleaning of the uneven wall surface.

[0043] In this embodiment, a plurality of spray nozzles 341 are arranged on the upper and lower parts of the side of the water tank 34 facing the wall. The spray nozzles 341 are communicated with the water tank 34.

[0044] Among them, the spray nozzles 341 are atomizing spray nozzles. The liquid in the water tank 34 is sprayed out evenly on the wall surface by the spray nozzles 341 through a liquid pumping pump, and then cleaned by the cleaning assembly 3 to improve the decontamination effect.

[0045] During specific implementation, place the rewinding mechanism at the top edge position of the building to be cleaned, place the tractor at the outer wall of the ground floor, then control the rewinding mechanism to release the rope to the tractor, install the cleaning component on the rope, and fix the end of the rope to the tractor. Then control the cleaning component to move along the rope to gradually clean the wall. At the same time, the wall being cleaned can be detected in real time according to the detection device. When the cleaning is not thorough, the distance between the cleaning component and the wall can be changed through the anti-residue component to increase the cleaning intensity and improve the cleaning effect, avoiding incomplete cleaning caused by uneven walls.
