Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging equipment, in particular to a driving mechanism of a dredging device for a sewage pipe network. Background Art

[0002] The urban drainage system is a very important facility, mainly used for the discharge of sewage. The sewage pipe is an important part of the drainage system. The substances passing through the sewage pipe include not only sewage, but with the long-term use of the sewage pipe, some blockages will accumulate in the sewage pipe. These blockages greatly affect the amount of sewage discharged. When the sewage pipe is blocked, it needs to be dredged to ensure smooth drainage.

[0003] At present, the cleaning of sewage pipes is mostly done by flushing with a high-pressure pump device equipped with a water pipe, such as the utility model patents with announcement numbers CN220827891U and CN217079088U, which respectively disclose a municipal sewage pipe dredging device, both of which are equipped with a water pipe and a water outlet nozzle. In the above two schemes, a high-pressure device is used to transport water through a water pipe, and finally sprayed out through a nozzle. Under the backwash of the water, the nozzle moves and cleans the inside of the pipe at the same time, but the driving dredging efficiency of the dredging device in the prior art is low. Therefore, a driving mechanism with higher cleaning efficiency is needed, which can also break up the cleaned blockages for subsequent discharge. Summary of the invention
