Municipal engineering drainage manhole cover

Abstract

The invention discloses a municipal engineering drainage manhole cover. The municipal engineering drainage manhole cover comprises a stainless steel protection net, a rectangular opening, a manhole cover body, a spring, a bottom plate, a connecting plate and a rotating shaft. The rectangular opening is formed in the middle part of the manhole cover body, and the stainless steel protective net is welded to the upper surface of the rectangular opening. The bottom plate is mounted on the bottom surface of the rectangular opening, and the bottom plate is fixedly connected with the side of the rectangular opening through the spring. A groove is further formed in the bottom surface of the manhole cover body on the side of the rectangular opening, and the connecting plate matched with the grooveis hinged into the groove. The bottom plate is hinged to one end of the connecting plate, a through hole and a drain hole are formed in the manhole cover body, and phosphor stripes and reflective stripes are symmetrically arranged on the manhole cover body. The drainage manhole cover is simple in structure and convenient to use, when the amount of water is small, the water is directly discharged into the manhole cover through the drain hole; when the volume of the water is too large, the water pressure is greater than the tension of the spring, so that the bottom plate is opened for drainage;and the arranged phosphor stripes and the reflective stripes play an warning role at night, and better practical application value and promotion value are achieved.

Description

technical field [0001] The invention relates to the fields of water conservancy and municipal engineering, in particular to a drainage well cover for municipal engineering. Background technique [0002] In recent years, heavy rainfall and extreme weather have occurred frequently. Due to the unreasonable design of the sewer, the rainwater discharge rate is too slow, resulting in water accumulation, and many cars are submerged, causing huge losses to people. Often the staff manually open the manhole cover to drain the water. Sometimes the vortex formed by the drainage will cause danger to pedestrians. If the manhole cover is not modified, the problem of water accumulation on the road during heavy rain still cannot be solved. Contents of the invention [0003] The purpose of the present invention is to provide a municipal engineering drainage well cover to solve the problems raised in the above background technology. [0004] In order to achieve the above object, the present...
