[0026] Among them, the cleaning body 1 includes a main frame 11 and cleaning rollers 12. The cleaning rollers 12 are provided at both ends of the main frame 11. Auxiliary casters 13 are provided in the middle of both sides of the main frame 11. The wind pressing device 3 is provided on the main frame 11 to assist the cleaning body 1 to closely adhere to the curtain wall;

[0027] The angle adjustment mechanism 2 includes a first angle adjustment arm 21, a second angle adjustment arm 22, and an opening and closing device 23. The first angle adjustment arm 21 and the second angle adjustment arm 22 are connected to the main frame 11. The first angle adjustment arm 21 and the second angle adjustment arm 22 are both provided with connecting shafts. The opening and closing device 23 is installed between the two connecting shafts to control the spacing between the two connecting shafts.

[0028] Specifically, in order to improve the adaptability of the present invention to various special-shaped curtain walls, the angle adjustment mechanism 2 further includes a suspension arm 24 for connecting the towing rope and a slewing joint 25 for controlling the included angle between the suspension arm and the first angle adjustment arm. The suspension arm 24 is connected to the first angle adjustment arm 21 through the slewing joint 25. When encountering a stepped wall surface or an angled wall surface, the angle between the first angle adjustment arm 21 and the suspension arm 24 can be adjusted through the slewing joint 25, and then in cooperation with the wind pressure pressing device 3 to ensure that when the main frame 11 moves, the auxiliary caster 13 can contact the curtain wall. The suspension arm 24 is provided with a buffer rubber wheel 241 for contacting the curtain wall and a towing ring 242 for connecting the towing rope. The slewing joint 25 is mainly composed of a motor and a coupling. The motor rotor is fixed to the coupling, and the motor stator is fixed on the suspension arm 24.

Transmission wheels corresponding to each other are provided on both the side plate 113 and the cleaning roller 112, and the driving motor drives the cleaning roller to rotate by means of belt transmission. Correspondingly, other electrical devices, such as a power supply, a wireless communication module, a wired communication module, a data storage component, etc., can be arranged on the concave surface of the mounting plate.

[0033] See Figure 3 , to ensure that there is sufficient contact pressure between the cleaning body and the curtain wall so that the cleaning roller can effectively perform cleaning. The wind pressing device 3 includes a fan protection shell 31 and a blower 32 installed in the fan protection shell; the mounting plate 111 is provided with a plurality of mounting cylinders 115 adapted to the fan protection shell 31, and the blower 32 is installed in the mounting cylinder 115 through the fan protection shell 31. The blower 32 includes a fan rotating shaft 321, a fan motor 322 and fan blades 323. The arrangement of the mounting cylinder 115 and the fan protection shell 31 facilitates the present invention to increase or decrease the number of the wind pressing devices carried according to the actual working environment. At the same time, it protects the fan blades from being damaged by touching the outside world.

[0034] The mounting plate 111 is provided with a cleaning nozzle 116 and a water baffle 117 for connecting an external water pipe, and both the cleaning nozzle 116 and the water baffle 117 are arranged corresponding to the cleaning roller. The setting of the water baffle can prevent the electrical devices arranged on the concave surface of the mounting plate from being affected by splashing water.

[0035] For the convenience of the user to inspect the cleanliness of the cleaning operation and detect glass cracks, a video monitoring component 7 is provided on the first angle adjustment arm 21.
