[0021] The curved surface climbing cleaning device described in this embodiment drives the cleaning mechanism 200 to move through the climbing mechanism 100, and the cleaning mechanism 200 brushes and cleans the curved surface. During this process, the two frames 110 of the climbing mechanism 100 can rotate relative to each other, and the two floating frames 116 in any frame 110 can also rotate relative to each other, thereby ensuring that the wheel body 130 is always in contact with the curved surface 300 to be processed, and can drive the cleaning mechanism 200 to move stably along the surface of the curved surface 300 to be processed. Compared with conventional curved surface cleaning equipment at this stage, this application has significant advantages such as high flexibility of use, strong controllability, wide application range, high cleaning degree and stable processing process, and has broad application prospects in this field.

[0022] It should be noted that, for the sake of ease of expression, this embodiment defines the moving direction of the curved surface wall-climbing cleaning device as a first direction X, the width direction of the curved surface wall-climbing cleaning device as a second direction Y, and the height direction of the curved surface wall-climbing cleaning device as a third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

Specifically, the reset member 123 in this embodiment is preferably a spring, which can provide an elastic restoring force to the frame 110 when it rotates, so as to ensure that the frame 110 can abut against the wall surface to be cleaned.

[0024] See also Figures 2 to 4As shown, the frame 110 in this embodiment includes a connecting plate 111, a supporting plate 112, a fixing plate 114 and a top plate 113 connected end to end in sequence, wherein the connecting plate 111 and the fixing plate 114 are arranged at intervals along a first direction X, the supporting plate 112 and the top plate 113 are arranged at intervals along a third direction Z, the connecting assembly 120 is rotatably connected to the connecting plate 111, the two ends of the fixing shaft 115 are respectively penetrated and connected to the connecting plate 111 and the fixing plate 114, and the adjusting assembly 117 is arranged on the top plate 113. In this embodiment, the connecting plate 111, the supporting plate 112, the fixing plate 114 and the top plate 113 are all configured as a detachable connection structure to facilitate their disassembly and maintenance.

[0025] In this embodiment, the adjustment assembly 117 is configured as two adjustment plates detachably connected to the two floating frames 116, and the two adjustment plates can be connected to different positions of the frame 110 to adjust the floating frames 116. Specifically, the curved surface climbing wall cleaning device in this embodiment is suitable for curved surfaces with fixed curvatures, and the operator needs to adjust the adjustment plates according to the actual curved surface shape before the operation.

[0026] In the present embodiment, the frame body 110 in the wall climbing mechanism 100 can rotate around the adjustment axis 121, and at the same time, the floating frame 116 can also rotate around the corresponding fixed axis 115, thereby realizing the three-dimensional flexible movement of the wheel body 130, thereby achieving the purpose of always moving in conformity with the curved surface. In the present embodiment, two wheel bodies 130 are connected to any frame body 110, and the two wheel bodies 130 are respectively arranged on both sides of the frame body 110 in the second direction Y. In other embodiments, the number of wheel bodies 130 and the actual installation position can be adaptively adjusted according to actual usage requirements, and the present invention does not impose specific restrictions on this.

[0027] See also Figure 5 and Figure 6 As shown, the cleaning mechanism 200 in this embodiment further includes a driving assembly 240, which is used to adjust the actual working position of the connection housing 210 to ensure that the cleaning brush 230 can always be stably attached to the curved surface to be cleaned.

Specifically, the rotating driver 241 in this embodiment is preferably a motor.

[0028] Furthermore, the cleaning brush 230 in this embodiment is configured as a rolling brush extending along the second direction Y, which can rotate around its axial direction to achieve brushing treatment of the curved surface to be cleaned. Furthermore, in order to improve the cleaning degree of brushing, the cleaning mechanism 200 in this embodiment also includes at least one nozzle 250, and the nozzle 250 is externally connected to a cleaning medium supply device, which is connected to the housing 210 and is arranged toward the inside of the housing 210 to spray the cleaning medium toward the working range of the cleaning brush 230. Specifically, in this embodiment, three nozzles 250 are evenly spaced in the second direction Y to improve the uniformity of spraying the cleaning medium.

Therefore, the cleaning mechanism 200 in this embodiment also includes a stop brush 220, which is connected to the shell 210, extending toward the curved surface 300 to be processed and arranged around the opening to stop excess cleaning medium and contaminants.

Any of the scrapers 140 extends along the second direction Y, is attached to the curved surface 300 to be processed, and is arranged on the moving path of the cleaning mechanism 200. Specifically, the wall climbing mechanism 100 in this embodiment is provided with two scrapers 140, and the two scrapers 140 are respectively connected to the two frames 110.

[0031] In summary, see Figure 7 As shown, in this embodiment, the wall-climbing mechanism 100 can ensure that the cleaning mechanism 200 can always stably adhere to the curved surface to be cleaned during the movement through its three-dimensional adjustment. The cleaning mechanism 200 can clean the curved surface through the combined action of the leave brush, the nozzle 250 and the stop brush 220. Finally, the scraper 140 can remove the residual watermarks on the curved surface, thereby realizing a complete curved surface cleaning process. Embodiment 2

[0033] Furthermore, in this embodiment, the operator can perform real-time regulation of the wall climbing mechanism 100 and the cleaning mechanism 200 through the control system, thereby improving the flexibility of use of the device, and can also preset parameters through the control system, thereby improving the degree of automation of the device.
