An anti-clogging manhole cover with adjustable flow holes for urban roads

Abstract

The invention discloses an anti-blocking well lid capable of adjusting a drain hole used for an urban road. The anti-blocking well lid comprises a well lid body and a first cavity which is located inthe well lid body, the well lid body is internally and fixedly provided with a top-bottom-through ladder-shaped cavity which is located on the lower side of the first cavity, and accumulated water onthe urban road surface can flow into a sewer through the first cavity and the ladder-shaped cavity. According to the well lid capable of adjusting the size of the drain hole, when a rainfall detectiondevice detects that the rainfall amount in unit time is too large, and the size of the drain hole can be enlarged by the anti-blocking well lid, so that the drain amount in unit time is increased; analarm device can give out a warning tone, so that pedestrians and vehicles on a road are reminded to be away from the well lid, the safety of people is guaranteed; and a cleaning device can clean thedrainage hole in time, so that the drain hole is prevented from being blocked to affect normal drainage of a city.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to an anti-clogging manhole cover with adjustable water holes for urban roads. Background technique [0002] The drainage system of urban roads is a manhole cover and other equipment that drains water from the road surface to the sewer in a city under special circumstances such as excessive rainfall. The traditional drainage manhole cover hole is a fixed size. In the case of a sudden increase in precipitation, The drainage effect is poor, and it is easy to produce accumulated water that will affect the urban road surface and affect the safety of vehicles and pedestrians. Therefore, there is an urgent need for an anti-clogging manhole cover with adjustable water holes for urban roads to solve the above problems. In view of the above shortcomings, this Invention improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to pro...
