Open the opening and closing door 13 (in the initial state, there is only the cleaning sphere 6 in the cleaning box 10, and there is no water body), and the upper end of the automobile pipe to be cleaned is penetrated from the bottom of the multi-stage clamp 3 (preferably against the partition plate 1 ). The bottom surface of the pipe fitting can prevent the outflow of water), select a suitable arc-shaped splint 301 (the inner arc of the arc-shaped splint 301 can fit with the outer circle of the pipe fitting) to clamp the pipe fitting, and the arc-shaped splint above the arc-shaped splint 301 is used. 301 are all squeezed to the side away from the pipe fitting, and the corresponding arc-shaped splints 301 of the left and right clamping pieces form a complete disk outside the pipe fitting, so that the periphery of the pipe fitting is clamped, and the clamping stability is good; the pipe fitting The part below the clamping part can be in a curved state or a straight state, that is, it is suitable for straight pipes and curved pipes;

After closing the opening and closing door 13, start the rotary motor 26 and the water pump 33, and the rotary motor 26 drives the auger hoist 25 (the cleaning ball 6 will roll along the filter plate 9 to the port 11, and enter the auger hoist along the pipe 1 22 to lift. machine 25), the conveying blade 28 pushes the cleaning ball 6 up to the height of the discharge port 23, the cleaning ball 6 enters the return pipe 24 from the discharge port 23, and then rolls along the return pipe 24 to the discharge port 7, and then Enter the upper chamber 101 of the cleaning box 10 from the feeding port 7, and then drop from the through hole 2 to just enter the pipe fittings; at the same time, the water pump 33 extracts the water body in the water storage tank 37 and transports it to the water inlet 8 along the return pipe 32, and the water body is discharged from the water inlet. 8 Enter the upper chamber 101 of the cleaning box 10, and then drip down from the through hole 2 to just enter the pipe fitting;

Because the rolling property of the sphere is the most flexible, even if the pipe fitting is a curved pipe, the cleaning sphere 6 can still pass through the curved pipe smoothly, and the impact of the water body makes the cleaning sphere 6 more smooth in the pipe fitting; The bristles 63 can brush the inner wall of the pipe fitting. After starting the driving motor 52, it drives the driving gear 51 to rotate, the driving gear 51 drives the multi-stage clamp 3 to rotate, and the pipe fitting rotates accordingly, so that the cleaning sphere 6 in the pipe fitting moves horizontally during the falling process. The circular motion of the pipe is a spiral downward movement along the pipe, which can achieve an efficient cleaning effect on the pipe;

After the cleaning ball 6 falls from the pipe fitting, it enters the material lifting mechanism 20 along the filter plate, and can be returned to the upper chamber 101 of the cleaning box 10 through the material lifting mechanism 20 to realize the circulation; The lower part of the lower chamber 102 of the tank 10 enters the water purification mechanism 30 along the drain pipe, and enters the water storage tank 37 after purification treatment in this mechanism, and can re-enter the upper chamber of the cleaning tank 10 under the action of the water pump 33 In 101, the circulation effect is realized. The circulating action of the cleaning sphere 6 and the water body can repeatedly clean the pipe fittings for many times, and can use less related materials to achieve a better cleaning effect.
