A fixed plate 9 is mounted on the fixed box 5, and a drive motor 10 is mounted on the fixed plate 9. Transmission gears 11 are mounted on the motor shaft of the drive motor 10 and on the water outlet pipe 7. The water device includes a drain tank 12, which has an inlet 13 and an outlet 14. The outlet 14 is equipped with a filter screen 15. The bottom of the drain tank 12 is equipped with a drain pipe 16. A drain plate 17 is slidably installed inside the drain tank 12. The drain plate 17 is equipped with a drain outlet 18. An installation sleeve 19 is fixedly installed on the outlet pipe 7. An installation tube 20 is slidably installed on the installation sleeve 19. A cover plate 21 is installed on the installation tube 20. An installation plate 22 is installed inside the installation sleeve 19. An installation spring 23 is installed between the installation plate 22 and the installation sleeve 19.

[0030] In this embodiment, the cylinder is mounted on the support platform 2 using a clamping device. The drive cylinder 4 is activated, causing the fixed box 5 and the water outlet pipe 7 to move downwards. Simultaneously, the cover plate 21 abuts against the top of the cylinder. The external water pipe is connected to the inlet pipe 6, and water flows out through the nozzles 8 on the inlet pipe 6, the fixed box 5, and the water outlet pipe 7. Then, the drive motor 10 is activated, and the drive motor 10 drives the water outlet pipe 7 to rotate on the fixed box 5 through the engagement of the transmission gear 11. The rotation of the water outlet pipe 7 drives the nozzles 8 to rotate, thereby cleaning the circumference of the cylinder. The cover plate 21 prevents sewage from splashing out. Then, the drive cylinder 4 is activated again to move downwards. The cover plate 21 is pressed against the installation spring 23 in the installation sleeve 19 through the installation pipe 20 and the installation plate 22, which improves the stability and tightness of the cover plate 21 fastening. The drive cylinder 4 drives the nozzles 8 to adjust the height, thereby increasing the cleaning range and achieving comprehensive cleaning.

[0031] Please see Figures 4-5As one embodiment of the drainage device and clamping device: a movable rod 24 is slidably provided on the drainage tank 12. One end of the movable rod 24 is fixedly connected to the sewage discharge plate 17, and the other end is provided with a movable handle 25. A movable spring 26 is provided between the movable handle 25 and the drainage tank 12. A sealing ring 27 is provided between the movable rod 24 and the drainage tank 12. The clamping device includes an outer clamping frame 28 and an inner clamping frame 29. The inner clamping frame 29 is slidably provided on the outer clamping frame 28. A first spring 30 is provided between the inner clamping frame 29 and the outer clamping frame 28. A sliding groove 31 is provided on the support platform 2. A sliding block 32 is provided in the sliding groove 31. The outer clamping frame 28 is fixedly provided on the sliding block 32. A second spring 33 is provided between the sliding block 32 and the sliding groove 31. A sliding rod 34 is provided in the sliding groove 31. The sliding rod 34 passes through the sliding block 32.

[0032] More specifically, the wastewater generated during cleaning enters the drain tank 12 through the inlet 13. At this time, the drain outlet 18 of the drain plate 17 is misaligned with the drain pipe 16 of the drain tank 12, so that the wastewater is filtered through the filter screen 15 and discharged through the outlet 14. Impurities remain in the drain tank 12. When it is necessary to clean the drain tank 12, press the moving handle 25. The moving handle 25 moves the moving rod 24 and the drain plate 17, so that the drain outlet 18 on the drain plate 17 is aligned with the drain pipe 16. Continue to rinse with water to remove the wastewater. Impurities are discharged through the drain pipe 16, facilitating the cleaning of the drain tank 12 and improving practicality. When clamping the cylinder, the sliding block 32 moves on the sliding rod 34, compressing the second spring 33. The elastic force of the second spring 33 causes the outer clamping frame 28 to clamp onto the outer wall of the cylinder. At the same time, the first spring 30 is stretched, causing the inner clamping frame 29 to extend into the inner wall of the cylinder, thereby clamping the inner wall of the cylinder. This facilitates the clamping of cylinders with different wall thicknesses and diameters, improving the practicality and adaptability of the cleaning machine 1.

[0033] In summary, during the use or operation of the overall equipment: the cylinder is mounted on the support platform 2 using a clamping device. The drive cylinder 4 is activated, causing the fixed box 5 and the water outlet pipe 7 to move downwards. Simultaneously, the cover plate 21 is pressed against the top of the cylinder. The external water pipe is connected to the inlet pipe 6, and water flows out through the nozzles 8 on the inlet pipe 6, the fixed box 5, and the water outlet pipe 7. Then, the drive motor 10 is activated, and the drive motor 10, through the engagement of the transmission gear 11, drives the water outlet pipe 7 to rotate on the fixed box 5. The rotation of the water outlet pipe 7 drives the nozzles 8 to rotate, thereby cleaning the circumference of the cylinder. The cover plate 21 prevents sewage from splashing out. Then, the drive cylinder 4 is activated again to move downwards. The cover plate 21, through the mounting pipe 20 and the mounting plate 22, presses the mounting spring 23 within the mounting sleeve 19, improving the stability and tightness of the cover plate 21's fastening. The drive cylinder 4 drives the nozzles 8 to adjust their height, thereby increasing the cleaning range and achieving comprehensive cleaning.

[0034] Wastewater generated during cleaning enters the drain tank 12 through the inlet 13. At this time, the drain outlet 18 of the drain plate 17 is misaligned with the drain pipe 16 of the drain tank 12, allowing the wastewater to be filtered through the filter screen 15 and discharged through the outlet 14. Impurities remain in the drain tank 12. When it is necessary to clean the drain tank 12, press the moving handle 25. The moving handle 25 moves the moving rod 24 and the drain plate 17, aligning the drain outlet 18 on the drain plate 17 with the drain pipe 16. Continue rinsing with water to remove the wastewater. Impurities are discharged through the drain pipe 16, facilitating the cleaning of the drain tank 12 and improving practicality. When clamping the cylinder, the sliding block 32 moves on the sliding rod 34, compressing the second spring 33. The elastic force of the second spring 33 causes the outer clamping frame 28 to clamp onto the outer wall of the cylinder. At the same time, the first spring 30 is stretched, causing the inner clamping frame 29 to extend into the inner wall of the cylinder, thereby clamping the inner wall of the cylinder. This facilitates clamping cylinders with different wall thicknesses and diameters, improving the practicality and adaptability of the cleaning machine 1.
