[0026] As Figures 1 to 3 shown, the present utility model provides a wall-climbing cleaning robot, including a wall-climbing driving mechanism 1, and a wall surface pre-cleaning mechanism 2 is arranged on the front side surface of the wall-climbing driving mechanism 1;

[0027] The wall-climbing drive mechanism 1 specifically includes a housing 11 and two drive motors 13 fixed in the inner cavity of the housing 11, the output shaft of the drive motor 13 is connected to a drive magnetic roller 12 located at the bottom of the housing 11, and a water gun controller 14 is fixed on the top surface of the housing 11, and a high-pressure water gun 15 is mounted on the upper surface of the water gun controller 14;

[0028] Refer to the instruction manual Figure 3 The wall pre-cleaning mechanism 2 includes two fixed plates 21 arranged in a mirror-symmetrical manner on the left and right, a rotating plate 28 rotatably connected to the fixed plates 21 on the side away from each other, and a crossbeam 23 fixed to the front surface of the rotating plate 28, and two convex plates 27 are fixed to the front surface of the crossbeam 23, a servo motor 24 is fixed to the right surface of the left convex plate 27, a brush roller 26 is fixedly connected to the output shaft of the servo motor 24, and a rubber scraper 25 is fixed to the front surface of the convex plate 27.

[0029] Specifically, the front side surface of the shell 11 of the present embodiment is provided with an inwardly recessed groove, and the left and right side surfaces of the inner cavity of the groove are rotatably connected to a driven magnetic roller 17, the top end face of the shell 11 is fixed with an end cover 16, and the bottom surface of the water gun controller 14 is fixedly connected to the top surface of the end cover 16, and the bottom surface of the shell 11 is provided with two rectangular through holes arranged in a left-right mirror-symmetrical manner for allowing the bottom surface of the outer ring of the driving magnetic roller 12 to be exposed from the inside of the shell 11, and the rear side of the surface of the fixing plate 21 that is away from each other is fixedly connected to the inner wall of the groove on the front side of the shell 11.

[0030] More specifically, the top surface of the cross beam 23 of the present embodiment is hinged with two servo electric cylinders 22 which are arranged in left-right mirror symmetry. The end of the servo electric cylinder 22 away from the cross beam 23 is hinged to the front area of the top surface of the end cover 16. The end of the brush roller 26 away from the output end of the servo motor 24 is rotatably connected to the left surface of the right convex plate 27.

[0031] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0032] After the wall-climbing cleaning robot is connected to the surface of the outer shell 11 and the end cover 16 with an anti-fall protection rope, it uses the magnetism of the driving magnetic roller 12 and the driven magnetic roller 17 to adsorb to the inner wall of the reactor, and drives the driving magnetic roller 12 to rotate back and forth through the driving motor 13.

[0033] During the process of the wall-climbing driving mechanism 1 moving spirally upward or downward along the inner wall of the reaction kettle, the telescopic shaft of the servo electric cylinder 22 extends and presses down the cross beam 23. After being pressed, the rotating plate 28 rotates along the rotation point with the fixed plate 21, so that the front end of the rubber scraping strip 25 contacts the inner wall of the reaction kettle. At the same time, the deformation ability and toughness of the rubber scraping strip 25 can fit with the arc surface of the inner wall of the reaction kettle, and the residual materials on the inner wall of the reaction kettle are scraped off. The scraped residual materials will be concentrated at the bottom of the reaction kettle and can be recycled and reused.

[0034] At the same time, during the process of the servo electric cylinder 22 pressing down, the brush roller 26 is forced to contact the inner wall of the reaction kettle. The brush roller 26 is driven to rotate by the servo motor 24, so that the inner wall that has been scraped once by the rubber scraping strip 25 is further rotated and scrubbed once. In addition, the high-pressure water gun 15 above the water gun controller 14 can also spray high-pressure water flow onto the inner wall that has been scraped and scrubbed, so as to thoroughly clean the inner wall surface of the reaction kettle with less water consumption.
