Well lid with rapid dredging function

Abstract

The invention discloses a well lid with a rapid dredging function. The well lid comprises a well lid body, a flood control disc is arranged on the well lid body, a plurality of drainage holes inclined in the circumferential direction of the well lid body are formed in the periphery of the flood control disc, a mounting frame is arranged at one end of the flood control disc, a rotating shaft is arranged on the mounting frame, the rotating shaft is connected with a rotating rod through a third connecting sleeve, the rotating rod is provided with a plurality of dredging rods, and the side, close to the well lid body, of the rotating rod is connected with a vane plate through a vertical rod. When the well lid discharges water, the water can flow out spirally and downwards in the inclined direction of the drainage holes, in the flowing-out process, the water flow flushes towards an impeller plate and drives the impeller plate to move, the impeller plate moves to drive the rotating shaft to rotate so as to drive the dredging rods to do circular motion around the rotating shaft, so that the lower portion of the well lid is dredged, water flow power during drainage is utilized in overall dredging treatment, resources are saved, dredging treatment can be automatically completed, and use is quite convenient.

Description

technical field [0001] The invention relates to the field of manhole covers, in particular to a manhole cover with a quick dredging function. Background technique [0002] The sewer is one of the most important components of urban flood control. In order to play a role in safety and protect the environment, it is necessary to install a manhole cover on the top of the sewer. [0003] At present, manhole covers used in urban sewers are mostly composed of simple filters and protective covers, and these manhole covers do not have the function of automatic dredging. When encountering heavy rain, the water flow on the road is large, and the road There will be a certain amount of garbage mixed with rainwater. When the rainwater flows from the manhole cover to the sewer, the garbage will block the filter screen, causing a large area of ​​urban roads to accumulate water, which brings great inconvenience to urban traffic. SUMMARY OF THE INVENTION [0004] The purpose of the present...

Problems solved by technology

[0003] At present, most of the manhole covers used in sewers in cities are composed of simple filters and protective covers, and these manhole covers do not have the function of automatic dredging. There will be a certain amount of garbage mixed with rainwater. When the rainwater flows from the manhole cover into the sewer, the garbage will block the filter screen, causing large areas of urban roads to accumulate water, which brings great inconvenience to urban traffic.
