Working principle: the device is activated after the operator places the device inside the pipe.
At this time, the first driving motor 21 is started, and the output end of the first driving motor 21 drives the second gear 23 to rotate, so as to drive the first gear 22 meshed with the second gear, so as to drive the rotating shaft 16 with one end provided with the first gear 22 to rotate, so as to drive the rotating wheels 17 at two ends of the rotating shaft 16 to rotate, so as to drive the crawler 18 matched with the outer sides of the rotating wheels 17 to rotate, and thus the equipment moves forwards.
The main detecting head 12, the top detecting device 13 and the side wall detecting device 14 which are arranged on the main machine shell 10 detect the inside of the pipeline respectively in the moving process of the equipment, the pump 42 is started so as to push water to all parts in the equipment, at the moment, the hydraulic bin inlet 37 at the top of the crushing hydraulic bin 25 starts to feed water, the connecting pressing block 31 arranged below the hydraulic bin inlet 37 is pushed to move downwards, the crushing roller 26 arranged on the connecting pressing block 31 is also pushed to move downwards, the crushing roller 26 is attached to the bottom pipe wall, after the crushing roller 26 is attached to the bottom pipe wall, the crushing roller 26 cannot move downwards continuously, at the moment, the liquid inlet piston 35 arranged in the cleaning bin inlet 34 starts to bear force, so that the liquid inlet piston 35 is pushed to move downwards until the liquid inlet piston 35 moves below the cleaning bin inlet 34, so that water flows into the cleaning nozzle 40 starts to work, and the water flows to the crushing roller 26 and the bottom pipe wall are ejected.
At this time, the third driving motor 63 disposed in the crushing hydraulic bin 25 is also started, and the output end of the third driving motor 63 drives the crushing shaft 62 to rotate, so as to drive the crushing roller 26 disposed on the crushing shaft 62 to rotate, so as to drive the crushing teeth 28 disposed on the crushing roller 26 to rotate, so as to drive the groove 29 disposed on the surface of the crushing roller 26 to rotate, so as to drive the connecting rod 27 disposed in the groove 29 to rotate, and thus drive the flexible belt 30 disposed outside the connecting rod 27 to rotate.

In the process of rotating the crushing roller 26, the telescopic pipeline 43 is also fed with water through the telescopic pipeline liquid inlet 44, so that the hydraulic telescopic rods 39 at two sides are pushed outwards until the buffer contact wheels 52 arranged at the outer sides of the hydraulic telescopic rods 39 are contacted with the pipe wall and then stop moving, in the process of contacting the buffer contact wheels 52 with the pipe wall, the buffer base 51 is connected to the bottom of the buffer contact wheels 52, the third spring 50 is arranged below the buffer base 51, so that damage caused in the process of contacting the buffer contact wheels 52 with the pipe wall is avoided, and a plurality of contact points are increased in the process of cleaning the pipeline by the design equipment, so that the equipment moves smoothly and rollover is avoided.
During the outward movement of the hydraulic telescopic rod 39, the linkage plate 65 arranged on the outer side of the buffer bin 49 will also move outwards, so that the high-pressure water pipe 38 arranged on the other side of the linkage plate 65 is driven to move outwards, at this time, the high-pressure water pipe 38 will also start to work, and then high-pressure water flow is sprayed into the pipe through the high-pressure spray nozzle 66, so that the rest part of the pipe wall is cleaned.
After the equipment runs for a period of time, impurities in the pipeline are removed completely, the main detector 12, the top detector 13 and the side wall detector 14 which are arranged on the host shell 10 also send detection results into the control panel 11, so that the damaged condition in the pipe wall is fed back to operators, and after the operators make an instruction whether to repair or not according to the condition, the equipment performs the next operation according to the instruction.
If the repairing is needed, the second driving motor 46 is started, the output end of the second driving motor 46 drives the transmission shaft 47 to rotate, so that the repairing turntable 20 arranged on the transmission shaft 47 is driven to rotate, the repairing liquid bin 55 filled with repairing liquid is driven to rotate to a position needing repairing, the heating bin 60 arranged on the repairing turntable 20 is driven to rotate to a position needing repairing, at the moment, the heating bin 60 is started, hot air is blown to the position needing repairing, and drying treatment is carried out on the position needing repairing, and after drying is finished. The pushing cylinder 54 arranged in the pushing bin 53 is also started, the output end of the pushing cylinder 54 pushes the pushing rod 56 to move forwards, so that the pushing plate 57 arranged on the pushing rod 56 pushes one side of the repairing liquid bin 55, repairing liquid in the repairing liquid bin 55 flows out to the liquid spraying port 58, and finally the repairing liquid is sprayed at the damaged position of the pipeline, at the moment, the heating bin 60 continuously works, and the repairing liquid is dried, so that the repairing liquid is tightly attached to the damaged position, and the occurrence of air bubbles at the attached position is avoided.
If no repair is needed, the repair rotary table 20 rotates the repair liquid bin 55 with the marking liquid to a corresponding position, so that the marking liquid is sprayed at the position, and a subsequent operator can quickly find the position when repairing.
