[0002] Municipal engineering refers to municipal infrastructure construction projects. Municipal infrastructure refers to various buildings, structures and equipment set up within the planning and construction scope of urban areas and towns to provide residents with paid or free public products and services based on government responsibilities and obligations. In municipal engineering, sewage needs to be pumped out, mainly through water pumps and other devices connected to the water inlet of the water pump to achieve the effect of filtering and pumping out dirty water.

[0003] For example, the Chinese utility model patent with publication number "CN218292202U" discloses a drainage device that can clean impurities such as branches and sludge by cooperating with a scraper rod and a cleaning brush. The cleaning effect is good and highly targeted, and no manual cleaning is required during drainage, making it easy to use.

[0004] However, in the above patent, only large impurities contained in sewage can be filtered, but large impurities contained in sewage cannot be processed, which easily causes impurities to accumulate in water pipes, causing pipe blockage, and workers are required to clean the pipes, causing inconvenience in use.
