[0042] When the insertion tube 8 needs to be inserted into the pipeline body 2, the first motor 16 is started, and the first motor 16 drives the third shaft 15 to rotate through the two first gears 17, and the third shaft 15 drives the second shaft 13 to rotate, and the second shaft 13 drives the second roller 14 to rotate, and the second roller 14 cooperates with the first roller 12 to transport the insertion tube 8 located in the rolling groove upward, so that the insertion tube 8 can smoothly enter the pipeline body 2. When the insertion tube 8 needs to be retracted, it is only necessary to rotate the second roller 14 in the opposite direction to retract the insertion tube 8;

[0043] When the insertion tube 8 enters the pipeline body 2, the insertion tube 8 drives the vertical tube 7 to move upward, and the vertical tube 7 drives the third gear 26 to move upward. When the insertion tube 8 completely enters the pipeline body 2, the third gear 26 moves to the bottom of the second fixed plate 18, and the third gear 26 meshes with the second gear 25. When water is ejected from the through hole 9, the second motor 22 is started, and the second motor 22 drives the fourth rotating shaft 20 to rotate through the first pulley 21, the second pulley 23 and the transmission belt 24. The fourth rotating shaft 20 drives the second gear 25 to rotate, and the second gear 25 drives the vertical tube 7 and the insertion tube 8 to rotate through the third gear 26, so that the insertion tube 8 rotates in the pipeline body 2 and continuously ejects water, and the spraying direction of the water is changed at all times, so that the stains in the dead corner are washed away, which is conducive to cleaning the pipeline body 2;

[0044] Before the insertion tube 8 enters the pipeline body 2, the first electric push rod 27 is started, the first electric push rod 27 drives the lifting plate 28 to move upward, the lifting plate 28 drives the hollow lifting column 29 to move upward, and the hollow lifting column 29 is inserted into the pipeline body 2 through the connecting tube 31, so as to facilitate the subsequent insertion of the insertion tube 8 into the pipeline body 2;

[0045] After the hollow lifting column 29 is inserted into the pipeline body 2, water is filled into the extension tube 8, and the water will enter the hollow column 30 and the hollow lifting column 29 from the through hole 9. The amount of water in the hollow column 30 and the hollow lifting column 29 increases, and the water can push the folding plate 32 upward. The water can also enter the liquid capsule 33 through the hose 34, so that the liquid capsule 33 continues to expand. The folding plate 32 drives the continuously expanding liquid capsule 33 to move upward. The liquid capsule 33 leaves the hollow lifting column 29 from the first rectangular opening 36 under the blocking effect of the inclined plate 35, and the liquid capsule 33 enters the pipeline body 2 and continues to expand until the liquid capsule 33 blocks the pipeline body 2, thereby preventing water from entering the ventilator and the mesh cover at both ends of the pipeline body 2 during the cleaning process. When the inclined surface of the folding plate 32 is located above the second rectangular opening 37, the insertion tube 8 can enter the pipeline body 2 under the guidance of the folding plate 32. When it is necessary to suck out the water in the pipeline body 2, the water in the pipeline body 2 is sucked out through the insertion tube 8 and the through hole 9. In this process, the water in the hollow column 30 and the hollow lifting column 29 will also be sucked out, and the water in the hollow column 30 and the hollow lifting column 29 will be reduced. The water in the liquid capsule 33 enters the hollow column 30 and the hollow lifting column 29 through the hose 34, so that the water in the liquid capsule 33 is reduced, and the folding plate 32 will gradually move downward, and the liquid capsule 33 returns to the hollow lifting column 29. Finally, the hollow lifting column 29 is controlled to leave the pipeline body 2 by the first electric push rod 27;

[0046] During normal use of the pipeline body 2, the four sealing pieces 39 can seal the two ends of the pipeline body 2 to prevent gas from escaping, and the connecting rope 40 is in a stretched and taut state. When the hollow lifting column 29 moves upward and is inserted into the connecting pipe 31, the sealing piece 39 rotates and the connecting rope 40 is stretched. When the hollow lifting column 29 leaves, the four sealing pieces 39 are reset and re-seal the connecting pipe 31 under the action of the connecting rope 40.

[0047] When the pipeline body 2 needs to be cleaned, the water pump 4 is started, and the water pump 4 draws water from the first water tank 3 through the fixed pipe 46, the telescopic pipe 47 and the first L-shaped pipe 5, and the water is transported to the T-shaped pipe 6 through another fixed pipe 46 and the telescopic pipe 47, and the water can be transported to the pipeline body 2 through the insertion pipe 8. When the water in the pipeline body 2 needs to be sucked out through the insertion pipe 8, the two second electric push rods 44 are started, and the second electric push rods 44 drive the telescopic pipe 47 to retract into the fixed pipe 46 through the moving plate 45, and the third electric push rod 49 is started, and the third electric push rod 49 passes through the limiting The positioning block 50 and the limiting opening 51 drive the connecting column 52 to move, and the connecting column 52 can drive the circular plate 43 and the water pump 4 to rotate ninety degrees. The circular plate 43 rotates on the third fixed plate 41 through the rotating column 42, and the two second electric push rods 44 are started. The second electric push rods 44 drive the telescopic tube 47 to move through the moving plate 45, so that the rubber sleeve 48 is sleeved on the T-shaped tube 6 and the second L-shaped tube 61, so that the water suction port of the water pump 4 is connected to the T-shaped tube 6, and the water outlet of the water pump 4 is connected to the second L-shaped tube 61. When the water pump 4 is turned on, water can be sucked into the second water tank 60 through the extension tube 8;

[0048] During the cleaning process of the pipeline body 2, the corresponding solenoid valve 57 is opened, and the disinfectant in the liquid storage box 55 enters the T-shaped tube 6 through the filling tube 56. The disinfectant is mixed with the water passing through to disinfect the pipeline body 2. After the disinfectant cleaning is completed, the solenoid valve 57 is closed to suck out the disinfectant in the pipeline body 2, and then the disinfectant is rinsed off with water. Finally, the corresponding solenoid valve 57 is opened, and hot air is blown into the pipeline body 2 through the drying equipment 59 to accelerate the drying of the pipeline body 2. The mesh cover and the pipeline body 2 can be limited and fixed by setting the L-shaped plate 53, which is convenient for the insertion tube 8 to enter the pipeline body 2. The pipeline body 2 can be limited and fixed by setting the rubber block 54 to prevent the pipeline body 2 from shaking randomly during the cleaning process.
