A horizontal shaft 43 is fixedly arranged inside the annular groove of the side wall ring 41. A sliding block 44 is slidably arranged on the outer side of the horizontal shaft 43. Long rods 5 are fixedly arranged at the middle positions where the two side wall rings 41 face each other. A traction rope 6 is fixedly arranged on the outer side of the long rod 5. One end of the traction rope 6 is fixedly arranged with a winding seat 7. A transmission shaft 8 is fixedly arranged at the top end of the winding seat 7. During the rotation of the transmission shaft 8, the winding seat 7 can be driven to traction the inner wall cleaning assembly 4 of the tank body to move and clean on the inner wall of the horizontal tank body 1.

[0029] Specifically, a guiding block 47 is fixedly arranged at the middle position of the sliding block 44. A sliding groove frame 48 is slidably arranged outside the guiding block 47, and the sliding groove frame 48 is fixedly arranged with the horizontal tank body 1.

[0035] Working principle and process:

[0036] When it is necessary to clean the inner wall of the horizontal tank body 1, the connecting pipe can be separated from the port of the oil injection pipe 3 of the horizontal tank body 1, the water injection structure is connected, the cleaning liquid is poured into the interior, and the driving structure, such as a motor structure, is inserted into the top notch of the transmission shaft 8. By driving the motor to work, the rotation of the transmission shaft 8 can be controlled to rotate inside the bearing 10 of the fixed block 9. With the sealing of the positioning piece 11 and the sealing cap 12, the rotation of the transmission shaft 8 is limited. The transmission shaft 8 can control the winding seat 7 at the bottom end to rotate, and the traction rope 6 is wound and pulled. The cleaning liquid first cleans the liquid impurities inside the horizontal tank body 1. At the same time, some solid-liquid mixtures are soaked and softened, and the side wall ring 41 structure in the cleaning assembly 4 inside the tank body is moved by traction. The movement of the side wall ring 41 structure on the inner wall of the horizontal tank body 1 can be controlled, and the inner wall of the horizontal tank body 1 is efficiently cleaned in cooperation with the cleaning scraper 42, including scraping off some solid-liquid mixtures adhered to the inner wall of the horizontal tank body 1, and the cleaning effect for the solid-liquid mixtures is better, effectively avoiding the inability to clean the solid-liquid mixtures. After controlling the driving motor to drive the transmission shaft 8 to rotate until it cannot move, the driving motor is turned off and removed from the top end of the transmission shaft 8. By moving the counterweight rope 13 at the other end of the traction rope 6 inside the cross frame 14, the counterweight block 16 at the bottom end of the spring ring 15 can fall off, and the side wall ring 41 in the cleaning assembly 4 inside the tank body is connected and pulled through the long rod 5, and pulled back for secondary cleaning.
