[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] Combine Figure 1-Figure 3 A walking device of an inclined climbing window cleaning machine includes a chassis 1 and two cleaning discs 2. The two cleaning discs 2 are installed on the top of the chassis 1. A negative pressure groove 3 is provided in the center of the top of the chassis 1. Moving mechanisms 4 are installed on both sides of the chassis 1. A protective mechanism 5 is installed on the outside of the cleaning disc 2.

[0024] See Figure 2 , it is further obtained that the moving mechanism 4 includes two fixing frames 6 and two fixing plates 10, the two fixing plates 10 are respectively fixedly mounted on both sides of the chassis 1, and the two fixing frames 6 are respectively movably mounted on the top of the two fixing plates 10, and three rotating teeth 7 are movably mounted inside the two fixing plates 10, and motors 8 are mounted inside the rotating teeth 7 located in the middle on both sides, and rubber belts 9 are sleeved on the outside of the three rotating teeth 7, and four telescopic rods 11 are fixedly mounted on the bottom of the fixing frame 6, and the outer periphery of the telescopic rods 11 is sleeved with a first spring 12, and an air pump is provided inside the chassis 1, which forms a certain negative pressure in the negative pressure tank 3 through the air pump, so that the chassis 1 is adsorbed on the window glass.

[0025] The two fixing frames 6 and the fixing plate 10 are symmetrically arranged, and the rubber belt 9 is sleeved on the outside of the three rotating teeth 7 in a meshing connection. Through the rotation of the rotating teeth 7 and the meshing between the rubber belt 9, the rubber belt 9 is located on the surface of the window glass and moves.

[0026] The output shaft of the motor 8 is fixedly connected to the rotating gear 7. Limiting slots are provided on both sides of the top of the chassis 1. The motor 8 is located in the limiting slot and slides up and down. The two motors 8 drive the rotating gear 7 on both sides to rotate respectively, so as to move the chassis 1.

[0027] The telescopic rod 11 is slidably arranged inside the fixed plate 10. The diameter of the limit plate at the bottom end of the telescopic rod 11 is larger than the diameter of the rod body. The telescopic rod 11 is extended and contracted and the first spring 12 causes the fixing frame 6 to slide up and down.

[0028] Specifically, the negative pressure tank 3 forms a certain negative pressure through the air pump inside the chassis 1, so that the chassis 1 is adsorbed on the glass of the window. At the same time, the two rubber belts 9 and the two cleaning discs 2 are in contact with the glass. The motor 8 drives the rotating gear 7 to rotate and move. Under the extension and contraction of the telescopic rod 11 and the action of the first spring 12, the rubber belt 9 adapts to the contraction, so that the two cleaning discs 2 can contact the glass surface for cleaning.

[0029] Example 2

[0030] See Figure 3 , and on the basis of Example 1, it is further obtained that the protective mechanism 5 includes two protective rings 13, the two protective rings 13 are respectively installed on the outside of the two cleaning discs 2, and three groups of fixed columns 14 are fixedly installed on the outside of the protective rings 13. A telescopic column 15 is movably installed inside each group of fixed columns 14, and a buffer plate 16 is fixedly installed on the outer end of each group of telescopic columns 15. A second spring 17 is installed at the inner end of the telescopic column 15 and located inside the fixed column 14.

[0031] The protective ring 13 is fixed to the bottom of the chassis 1 . The inner diameter of the protective ring 13 is larger than the outer diameter of the cleaning disc 2 . The protective ring 13 is used to protect the outer ring of the cleaning disc 2 .

[0032] Three groups of fixed columns 14 are arranged in a ring shape, with each group of fixed columns 14 having three. The telescopic columns 15 are located inside the fixed columns 14 and are slidably arranged. Through the extension and retraction of the telescopic columns 15, the buffer plate 16 provides a certain buffer for the protective ring 13.

[0033] Specifically, when the buffer plate 16 contacts the external protruding structure, the telescopic column 15 and the second spring 17 provide buffering for the protective ring 13, reducing the collision with the chassis 1. The protective ring 13 provides protection for the cleaning disk 2, thereby reducing damage to the cleaning disk 2.

[0034] During actual operation, the chassis 1 is connected to a power source, and the drive system and air pump inside the chassis 1 rotate the two cleaning discs 2 to clean the window glass surface. At the same time, negative pressure is formed in the negative pressure tank 3, causing the chassis 1 to be adsorbed on the window glass surface.

[0035] When the machine case 1 is moving while being adsorbed on the glass surface, the two rubber belts 9 are in contact with the glass surface. By starting the two motors 8, the corresponding rotating teeth 7 are rotated, and the two rubber belts 9 are driven to rotate under the meshing action, so that the machine case 1 can move while cleaning. Through the extension and contraction of the telescopic rod 11 and the action of the first spring 12, the fixing frame 6 drives the rubber belts 9 to adapt and contract, thereby making the two cleaning discs 2 come into adaptive contact with the glass surface.

[0036] During protection, the buffer plate 16 contacts the external protruding structure, and the telescopic column 15 slides under the action of the second spring 17, providing a certain buffering effect on the protective ring 13, reducing the collision with the chassis 1, and providing protection for the periphery of the cleaning disk 2 through the protective ring 13, reducing damage to the cleaning disk 2 caused by external objects.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
