the body 1 can automatically move in the drainage pipeline by driving one of the rollers 6 to rotate through the motor, so that the operation steps of the device are further reduced, and the sealing effect on the pressure groove 2 is improved by arranging the sealing ring 7 to be mutually attached to the inner side wall of the pipeline, so that the detection precision of the pipeline is improved; the sealing ring 7 is inflated through the air supply component 3, the sealing ring 7 is expanded and is mutually attached to the inner side wall of a drainage pipeline, at the moment, the air supply component 3 supplies air and pressurizes the air to the inside of the pressure tank 2, so that the drainage pipeline is detected, then the air supply component 3 stops working, air in the sealing ring 7 is pumped out through the air pumping component 8, the sealing ring 7 is made to shrink and separate from the inner side wall of the pipeline, the motor drives the roller 6 to rotate, the body 1 is made to move to the next position, then the sealing ring 7 is made to expand and the next position is detected, and the cycle is carried out, so that the operation can avoid the problem that the sealing ring 7 is in long-time friction contact with the inner side wall of the pipeline, and the sealing ring 7 is rapidly worn and loses efficacy; during detection, the air supply assembly 3 supplies air to the pressure tank 2 for pressurization, if a leakage point exists at a certain position of the pipeline, the air in the pressure tank 2 overflows outwards through the leakage point, and then the flowing air flow drives the mounting block 11 and the sponge 12 nearby to move towards the leakage point, so that the sponge 12 extrudes the inner side wall of the pipeline and leaves a coloring agent at the leakage position, the leakage point is subjected to dyeing marking, and the positioning range of the leakage point is further narrowed; by arranging the storage cavity 14 and adding the coloring agent into the storage cavity, the absorbent cotton sliver 15 can absorb the coloring agent, so that the coloring agent in the storage cavity 14 is conveyed to the sponge 12, and the coloring agent is continuously supplemented for the sponge 12, so that the sponge 12 is kept in a full state, a coloring marking effect is more efficiently achieved, and the equipment can be recycled; by arranging the elastic sealing film 16 and completely coating the sliding hole 9, when the guide rod 10 slides in the sliding hole 9, the problem that the coloring agent in the storage cavity 14 overflows and leaks outwards through the sliding hole 9 can be avoided; when the device is in a non-detection state, the pair of arc-shaped elastic pieces 18 are close to each other and clamp the absorbent cotton sliver 15, so that the transmission speed of the coloring agent in the storage cavity 14 to the sponge 12 through the absorbent cotton sliver 15 is reduced, the problem that the coloring agent is evaporated and dissipated through the sponge 12 in a large amount to cause the coloring agent to be wasted in a large amount is solved, when the device is used for detection, the air supply assembly 3 supplies air and pressurizes air to the pressure groove 2, then the air enters the guide cavity 19 through the air inlet 22, the sliding piece 20 is pushed to slide in the guide cavity 19, and then the pair of arc-shaped elastic pieces 18 are pulled to be away from each other through the connecting rod 21, so that the arc-shaped elastic pieces 18 stop extruding the absorbent cotton sliver 15, and at the moment, the coloring agent in the storage cavity 14 can be conveyed to the sponge 12 at a normal speed; by arranging the rubber bag 23, when the pair of arc-shaped elastic sheets 18 are far away from each other, the sliding sheet 20 can synchronously extrude the air in the guide cavity 19 into the rubber bag 23 to promote the rubber bag 23 to expand and drive the absorbent cotton sliver 15 to expand, so that the absorbent cotton sliver 15 can automatically recover, and the problem that the absorbent cotton sliver 15 is plastically deformed and difficult to automatically recover after the arc-shaped elastic sheets 18 extrude the absorbent cotton sliver 15 for a long time is solved; through set up a plurality of support shell fragments 24 inside the sponge 12, can improve the supporting effect to sponge 12, improve the elasticity of sponge 12 self, avoid sponge 12 to extrude the back with the pipeline inside wall many times, sponge 12 takes place plastic deformation and is difficult to the problem of automatic recovery.
