[0026] As shown in Figure 5 , Figure 6 , the side wall of the piston plate 19 is provided with a sealing ring 2, and the sealing ring 2 is in sliding connection with the piston cylinder 18; by setting the sealing ring 2, the sealing property between the piston plate 19 and the piston cylinder 18 can be improved, and the problem of reduced suction force of the blockage caused by air leakage when the piston plate 19 slides in the piston cylinder 18 to adjust the air pressure can be reduced.

[0027] As shown in Figure 6 , Figure 7 , a plurality of cutting knives 3 are fixedly connected to the side wall of the piston plate 19, and the cutting knives 3 are in an array structure; in use, the piston plate 19 slides in the piston cylinder 18, and the cutting knives 3 move synchronously in the piston cylinder 18; when the blockage caused by the entry of the gelatinous mud blockage into the piston cylinder 18, the moving cutting knives 3 can cut the mud block, reducing the problem of large mud blockage blocking the piston cylinder 18; by setting the cutting knives 3, the piston plate 19 slides in the piston cylinder 18, and the cutting knives 3 move synchronously in the piston cylinder 18; when the blockage caused by the entry of the gelatinous mud blockage into the piston cylinder 18, the moving cutting knives 3 can cut the mud block, reducing the problem of large mud blockage blocking the piston cylinder 18.

[0029] As shown in Figure 1 , Figures 3 to 5 , the mud inlet 5 is a horn type, and the mud inlet 5 is located between the mud pipe 15 and the piston cylinder 18; by setting the mud inlet 5, the horn-shaped mud inlet 5 can increase the inlet area of the piston cylinder 18, and the horn-shaped inlet formed by expanding outward can avoid direct impact of sewage on the inner wall of the pipeline, reduce local resistance loss, reduce vortex and turbulent flow caused by sudden change of flow velocity, and reduce deposition of impurities at the inlet.

[0030] As Figure 1 , Figure 3 shown, the control box 6 is fixed to the side wall of the protection box 12, which is used for the start-stop control of the air inlet pump 13, the servo motor 103 and the suction pump 107. By setting the control box 6, the start-stop of the air inlet pump 13, the servo motor 103 and the suction pump 107 can be controlled.

[0031] The working principle is that, in use, the suction pump 107 is started, at which time the sludge enters the sludge conveying pipe 16 from the plurality of suction pipes 17, and then the sludge enters the sludge discharge pipe 15, realizing the suction of the sludge. When there is a blockage in the sludge discharge pipe 15, the servo motor 103 is started, and the servo motor 103 drives the screw rod 1 to rotate, at which time the connecting plate 102 slides upward on the screw rod 1, and the piston rod 101 drives the piston plate 19 to slide synchronously in the piston cylinder 18. When the piston plate 19 moves away from the sludge discharge pipe 15, the pressure in the piston cylinder 18 decreases, and the blockage is sucked into the piston cylinder 18 from the sludge discharge pipe 15. The servo motor 103 is adjusted to reverse the screw rod 1, the connecting plate 102 slides downward on the screw rod 1, and the piston rod 101 drives the piston plate 19 to move relatively close to the sludge discharge pipe 15, at which time the pressure in the piston cylinder 18 increases, and the blockage in the piston cylinder 18 is discharged into the sludge discharge pipe 15. The reciprocating movement of the piston plate 19 in the piston cylinder 18 can change the pressure in the piston cylinder 18, and the blockage in the sludge discharge pipe 15 is sucked into the piston cylinder 18 and then discharged. When the sludge discharge pipe 15 above the piston cylinder 18 is blocked, the first valve 104 is closed, the second valve 105 is opened, and the air inlet pump 13 is started to inflate the sludge discharge pipe 15, and the air pressure drives the blockage to be discharged from the end of the sludge discharge pipe 15 close to the suction pump 107. When the sludge discharge pipe 15 below the piston cylinder 18 is blocked, the second valve 105 is closed, the first valve 104 is opened, and the air inlet pump 13 is started to inflate the sludge discharge pipe 15, and the air pressure drives the blockage to enter the sludge conveying pipe 16 and then be discharged from the suction pipe 17, realizing the dredging and anti-blocking of the sludge discharge pipe 15. The piston plate 19 slides in the piston cylinder 18, and the cutting knife 3 moves synchronously in the piston cylinder 18. When the blockage of the gelatinous sludge enters the piston cylinder 18, the moving cutting knife 3 can cut the sludge block, reducing the problem of large sludge blocks blocking the piston cylinder 18. The piston plate 19 slides in the piston cylinder 18, at which time the water flow change drives the vortex fan 42 to rotate, and the rotating shaft 41 rotates synchronously. When the rotating shaft 41 rotates, the stirring rod 4 can stir the blockage entering the piston cylinder 18, reducing the problem of the blockage gathering to block the piston cylinder 18. The trumpet-shaped sludge inlet 5 can increase the inlet area of the piston cylinder 18, and the trumpet-shaped opening formed by the expansion can avoid the direct impact of the sewage on the inner wall of the pipeline, reduce the local resistance loss, reduce the vortex and turbulent flow caused by the sudden change of flow velocity, and reduce the deposition of impurities at the inlet.
