Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and in particular to a crushing mechanism and a pipeline desilting robot for pipeline desilting, and in particular to a crushing mechanism suitable for a horizontal well pipeline desilting robot. Background Art

[0002] Urban sewer pipes are the "blood vessels" of the city, shouldering the heavy responsibility of collecting and transporting urban sewage and rainwater, and are an important part of the urban water environment. However, as the use time increases, sewer pipes generally become clogged. Some are filled with muddy water mixed with silt, and some are clogged with garbage. The composition of the garbage varies, including soft plastic bags, textiles, and thin ropes, as well as hard bricks, stones, sticks, and metal rods. At present, the traditional method of cleaning sewer pipes is mainly manual, and silt and garbage are regularly pumped out at the manhole mouth by manual labor and taken away by tank trucks for centralized treatment.

[0003] The shortcomings of the existing technology are: first, due to the complexity of underground pipes, the manual cleaning process is complicated, and the cleaning is still inadequate or the garbage in the sewer pipes cannot be cleaned, which is inefficient; second, there are more toxic gases underground, which are more harmful to the human body.

[0004] There has been no particularly effective method for clearing the silt from underground horizontal wells. The conditions for clearing the silt are limited by the different diameters of sewage pipes, the different hardness and thickness of silt, and the complex composition of silt. When using robots to suck out the blockages, the robot's suction port is often blocked and the robot cannot move smoothly. The present invention solves this problem.

[0005] The patent document with publication number CN207776083U discloses a pipeline desilting robot and a pipeline desilting system having the robot, wherein the pipeline desilting robot includes a traveling vehicle and a sludge treatment device, wherein the traveling vehicle includes a carriage with a sludge treatment device at the front end, a power supply device and a control device arranged in the carriage, a signal feedback device arranged on the carriage, two traveling devices symmetrically arranged on the outer wall of the carriage and having anti-slip performance, a driving device arranged in the carriage for driving the two traveling devices to synchronously travel in the pipeline, and a sludge conveying component arranged on the outer wall of the carriage and connected to the sludge treatment device for conveying the sludge collected in the sludge treatment device to the outside of the pipeline. However, the patent document still has problems such as the robot's sewage suction port being blocked and the robot being unable to travel smoothly. Summary of the invention
