When the descaling work is completed, the lubricating liquid remaining in the gap between the wear-resistant and descaling sleeve 8 and the annular air bag 7 can be pumped out through the suction pipe connected to the delivery pipe 36, to prevent the lubricating liquid from being left for a long time and changing in viscosity, causing increased friction.

[0063] The working principle of the present application is as follows: the device is placed at the edge of the sewage treatment tank, and the annular air bag 7 is inflated to collide with the wear-resistant and descaling sleeve 8, which is then sent into the sewage treatment tank. The servo motor 15 drives the drive gear 16 to rotate, which in turn drives the inner ring gear 14 to rotate, which in turn drives the drive cylinder frame 13 to rotate, which in turn drives the wear-resistant and descaling sleeve 8 to rotate as a whole, thereby realizing the ability of the wear-resistant and descaling sleeve 8 to automatically drive the peripheral part to descale the sewage treatment tank, improving the cleaning effect and efficiency. During the rotation of the wear-resistant and descaling sleeve 8, the lubricating liquid is stored in the liquid storage cavity 10, and the lubricating liquid is supplied to the gap between the annular air bag 7 and the wear-resistant and descaling sleeve 8 through the plurality of liquid pumps 11, reducing the friction between the wear-resistant and descaling sleeve 8 and the annular air bag 7, thereby realizing the rotation and cleaning ability of the wear-resistant and descaling sleeve 8. The liquid pump 20 draws water from the stirring cavity 9 through the suction pipe 21 and delivers it to the flushing pipe 18 through the delivery pipe 22, and the plurality of nozzles 19 arranged on the flushing pipe 18 are uniformly sprayed, reducing impurities and improving cleaning effect.

[0064] In summary, by placing the device at the edge of the sewage treatment tank, the stretching arm 2 is extended from the water tank 1, and the drive frame 4 is pressed down by the electric push rod 3, so that the descaling frame 6 at the bottom of the drive frame 4 enters the sewage treatment tank. The annular air bag 7 is inflated, and the wear-resistant descaling sleeve 8 is expanded by the inflation of the annular air bag 7. The surface of the expanded wear-resistant descaling sleeve 8 contacts the tank wall of the sewage treatment tank. The wear-resistant descaling sleeve 8 is rotated as a whole by the driving assembly, so that the wear-resistant descaling sleeve 8 can clean the sewage treatment tank. The annular air bag 7 is deformed under pressure, so that the wear-resistant descaling sleeve 8 can uniformly scrub the recesses and gaps in the sewage treatment tank. The water flushing assembly sprays clean water or a mixture of clean water and cleaning agent, improving the cleaning effect of the sewage treatment tank. The stirring assembly realizes rapid mixing of clean water and cleaning agent. During the descaling process of the descaling frame 6, the rotation ability of the connecting arm 5 allows the descaling frame 6 to adjust the rotation angle, so as to better fit the curvature of the tank wall of the sewage treatment tank.
