Automatically dredging device of preventing perforated strainer of underground well from blocking

Abstract

The invention relates to the field of urban municipal drainage, in particular to an automatically dredging device of preventing a perforated strainer of an underground well from blocking. The device comprises a scraping rod, the scraping rod is movably arranged on the perforated strainer of the underground well, the scraping rod is connected to a driving device through a driving rod, the driving device drives the scraping rod to make straight reciprocating motions on the perforated strainer of the underground well, the output force of the scraping rod is no more than 10 kilogram force, when water current enters the underground well, the driving device drives the scraping rod to move, and when no water current enters the underground well, the driving device is in a quiescent state. According to the automatically dredging device of preventing the perforated strainer of the underground well from blocking, the structure is simple, the scraping rod is in the quiescent state when there is no rainwater, the driving device is used for driving the scraping rod to move when there is rain, so that leaves and municipal waste on the perforated strainer of the underground well are scraped and pushed away without intermittence and then the rainwater successfully flows into the underground well, therefore, the condition of water logging of a road is prevented; in addition, due to the fact that the output force of the scraping rod is no more than 10 kilogram force, the scraping rod has no potential safety hazards towards vehicles and pedestrians.

Description

technical field [0001] The invention relates to the field of urban municipal drainage, in particular to a device for self-dragging and preventing grate clogging in sewer wells. Background technique [0002] Sewer wells are ubiquitous in urban roads, and their main function is to alleviate the phenomenon of water accumulation caused by rain on urban roads, relieve urban drainage pressure, and reduce or prevent the inconvenience and insecurity caused by road accumulation water to people's lives. Since the drainage system was designed and installed very early, it is a water outlet connected to the urban drainage pipeline at the bottom of a civil engineering tank, and a sewer grate with permeable holes is installed on the upper part, and the rainwater enters the drain through the sewer grate. In the civil tank, into the drainage system. [0003] At present, the known sewer grate is made of ductile iron, engineering plastics, cement and other materials, and is drained by more th...
