[0023] Refer to Figures 1 to 4 , an automatic tank washing robot includes a fixing plate 10, a driving device 20, a fixing device 30, and a cleaning device 40. The driving device 20 is arranged on the fixing plate 10. The driving device 20 is used to drive the fixing plate 10 to move along the tank wall. The fixing device 30 is arranged on the driving device 20. The fixing device 30 is used to control the driving device 20 to adsorb on the tank wall. The cleaning device 40 is arranged on the fixing plate 10. The cleaning device 40 is connected to a pressure liquid supply system. The cleaning device 40 sprays cleaning liquid onto the tank wall.

[0024] It can be understood that through the fixing device 30, the driving device 20 and the fixing plate 10 can be adsorbed on the tank wall. Subsequently, the cleaning device 40 is moved by the driving device 20 to achieve the moving cleaning of the tank wall, greatly improving the cleaning efficiency of the tank wall and reducing the safety hazards brought by long-term manual cleaning.

[0025] Refer to Figures 1 to 4 , the driving device 20 includes a wheel frame 21 and a traveling wheel 22. The wheel frame 21 is arranged on the fixing plate 10. The traveling wheel 22 is rotatably arranged on the wheel frame 21.

[0026] It is understandable that in some embodiments of the present utility model, the wheel frame 21 is arranged on the fixed plate 10, and the driving wheel 22 can be driven to rotate by a motor or other existing power devices, driving the wheel frame 21 and the fixed plate 10 to move, and further driving the cleaning device 40 to move.

[0027] It should be noted that in some embodiments of the present utility model, a rubber anti-slip sleeve is sleeved on the driving wheel 22.

[0028] It should be noted that in some embodiments of the present utility model, anti-slip patterns are printed on the driving wheel 22.

[0029] Referring to Figures 1 to 4 , there are two groups of driving wheels 22. The driving device 20 further includes a balance wheel 23. The balance wheel 23 is arranged between the two groups of driving wheels 22. The contact points of the two groups of driving wheels 22 and the balance wheel 23 with the pipe wall form an isosceles triangle.

[0030] It is worth noting that through the balance wheel 23 and the two groups of driving wheels 22, the contact of the automatic tank washing robot with the tank wall can be the three points of an isosceles triangle, and the support is balanced and stable.

[0031] It should be noted that in some embodiments of the present utility model, the fixing device 30 is arranged on the wheel frame 21. The fixing device 30 is a magnet.

The blocking ring 441 is disposed on the cleaning rack 42 and is close to the tank wall. The suction port 442 is opened on the cleaning rack 42 and is located inside the blocking ring 441. The suction port 442 is connected to a negative pressure suction device.

[0039] It should be noted that in some embodiments of the present invention, the blocking ring 441 is used to block the splashing of the waste liquid after cleaning, and the waste liquid is concentrated in the enclosed space formed by the blocking ring 441, the cleaning rack 42 and the tank wall. Subsequently, the waste liquid is pumped out through the connection between the negative pressure suction device and the suction port 442 to prevent the waste liquid from flowing down, saving the time for subsequent waste liquid cleaning and further improving the cleaning efficiency.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
