Anti-blocking water absorption manhole cover

Abstract

The invention discloses an anti-blocking water absorption manhole cover which comprises a manhole cover body. Multiple water inlets are formed at the upper end of the manhole cover body in the circumferential direction of the manhole cover body at equal distance. Cavities are symmetrically formed in the manhole cover body. A first telescopic airbag is fixedly connected to the inner wall of each cavity, and a second telescopic airbag is arranged on the outer side of each first telescopic airbag in a sleeving manner. A dredging device used for dredging the water inlets is mounted on the manholecover body. According to the anti-blocking water absorption manhole cover, through the arrangement of an elastic plate, a vertical rod, first cross rods, second cross rods and sliding plugs, when a vehicle passes through the elastic plate, the vertical rod can drive the first cross rods to move through the second cross rods, the sliding pugs drive the first telescopic airbags and the second d telescopic airbags to be stretched, so that ejector rods move downwards, and the process that rainwater enters the water inlets is accelerated; and the situation that when the vehicle fast runs on the manhole cover body, rainwater on the manhole cover body is drained away, and the water drainage efficiency of the manhole cover body is influenced is avoided.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to an anti-clogging water-absorbing well cover. Background technique [0002] The well cover is a device used to cover the wellhead of the road drainage well and prevent people or objects from falling during the municipal construction process. [0003] With the long-term use of the road, there will be more impurities such as sand and gravel on the road. Since the water inlet of the manhole cover is slender, it is very easy to block the water inlet after the sand and gravel enter the water inlet. The discharge capacity of rainwater is reduced. In addition, when it rains, when motor vehicles and non-motor vehicles drive quickly on the manhole cover, the accumulated water on the manhole cover will be discharged to both sides, so that there is less water on the manhole cover, which will affect the safety of the manhole cover. At the same time, the accumulated water disch...

Problems solved by technology

[0003] With the long-term use of the road, there will be more impurities such as sand and gravel on the road. Since the water inlet of the manhole cover is slender, it is very easy to block the water inlet after the sand and gravel enter the water inlet. The discharge capacity of rainwater is reduced. In addition, when it rains, when motor vehicles and non-motor vehicles drive quickly on the manhole cover, the accumulated water on the manhole cover will be discharged to both sides, so that there is less water on the manhole cover, which will affect the safety of the manhole cover. Drainage efficiency, at the same time, the accumulated water discharged to both sides is easy to cause impact on pedestrians on the road, thus causing unnecessary troubles
