The working principle of the drainage pipe dredging equipment in this embodiment is as follows:

Put the desilting mechanism 1 into the pipe 2, and control the first electric telescopic rod 1107 on the driving mechanism 11 to be energized through the remote control device, thereby unfolding the movable arm 1102, so that the anti-skid tire 1106 on the wheel hub 1105 is in contact with the pipe 2 The inner wall of the pipe comes into contact, and then the second motor 1104 is energized to work, thereby driving the wheel hub 1105 to rotate, allowing the driving wheel 1106 to walk on the inner wall of the pipe 2, and observing the sludge condition on the inner wall of the pipe through the camera 9, while the desilting mechanism 1 is walking on the inner wall of the pipe At this time, the distribution box 71 is used to control the third motor 76 to rotate in the reverse direction, driving the gear in the second reduction box 75 to rotate, thereby driving the winding rod 73 to rotate in the reverse direction, and the winding rod 73 is used to rotate in the reverse direction, thereby rewinding The rope 5 wrapped around the rod 73 is released, allowing the dredging mechanism 1 to drive the rope 5 into the pipe 2 when walking. When the dredging mechanism 1 moves to the designated position, the second electric telescopic rod 1305 is controlled by the remote control device to contract. , thereby unfolding the mud scraper 1307, allowing one end of the mud scraper 1307 to contact the inner wall of the pipe 2, and then turning on the power through the stator coil on the stator fixed barrel 16, allowing the rotor fixed barrel 1301 to rotate around the stator fixed barrel 16, thereby driving The shovel 1307 rotates at high speed, and then uses the remote control device to control the operation of the air pump 21, thereby inflating the rubber airbag cover 23, causing the rubber airbag cover 23 to expand, so that the brush 24 on the rubber airbag cover 23 comes into contact with the pipe wall, and then through the fitting The electric box 71 controls the third motor 76 to be energized, thereby driving the winding rod 73 to rotate. The winding rod 73 is rotated to wind up the rope 5, thereby driving the desilting mechanism 1 to move from the pipe 2, without the need for the desilting mechanism 1. Providing power, when the mud scraper 1307 rotates at high speed, the sludge on the inner wall of the pipe 2 is shoveled out, and the first motor 18 is energized to drive the gear in the first reduction box 17 to rotate, thereby driving the auger 14 to rotate. Thereby, the sludge shoveled off the upper side of the inner wall of the pipe 2 falls into the mud port 15, and the sludge is transported to the connecting hose 4 through the auger 14, and is discharged from the pipe 2 through the connecting hose 4. In order to avoid excessive accumulation of sludge, The phenomenon of insufficient power of the desilting mechanism 1 also prevents excessive sludge from squeezing the sector-shaped steel plate 1307 when the rope 5 pulls the desilting mechanism 1, causing damage to the sector-shaped steel plate 1307. When the desilting mechanism 1 moves, a rubber air bag is used The brush 24 on the sleeve 23 scrapes the pipe 2 again, so that all the remaining sludge can fall off the inner wall of the pipe, and can be washed away by running water later.

This dredging equipment can be adapted to drainage pipes of different diameters, and the method is used to advance the dredging equipment to a designated position in the pipe, and then pull the dredging equipment back through the steel cable to pull the dredging equipment out of the pipe. , when pulling out, use the desilting equipment to quickly clean the silt on the pipe wall, and assist in transporting the silt through the mud transport pipeline, so that there will not be too much silt accumulated on the desilting equipment, and avoid the pulling rope from being broken, through This method can avoid the accumulation of silt in front of the dredging equipment and prevent it from being completely cleaned. Moreover, this method can use multiple cleanings to achieve segmented cleaning, reduce the power required by the dredging equipment, and avoid the phenomenon of slipping and being unable to move forward due to insufficient power. , this desilting equipment can also clean the remaining silt and moss after cleaning the silt on the pipe wall, making the cleaning more thorough.
