A municipal anti-theft manhole cover

Abstract

The invention relates to the technical field of municipal engineering devices, and provides a municipal anti-theft manhole cover. The manhole cover comprises a cover body, wherein the cover body is arranged on a base; drain holes, which are used for conducting drainage, are arranged in the cover body; a locking mechanism, by which the cover body is locked on the base, is arranged on the cover body; an opening component, which is used for opening the locking mechanism, is arranged at the bottom of the cover body; and the opening component is arranged between the cover body and the base. The cover body can be stably fixed to the base under a locking effect of the locking mechanism, so that a problem that the manhole cover can be stolen easily can be solved, and serious injuries on pedestrians and vehicles due to the absence of the manhole cover can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of municipal engineering devices, in particular to a municipal anti-theft manhole cover. Background technique [0002] As an important part of the urban drainage system, the sewer pipe has become an important municipal engineering facility in urban construction. At present, most of the sewer manhole covers are directly installed on the support of the sewer by using iron steel rings or concrete. [0003] At present, the national manhole cover devices are basically divided into two categories: [0004] 1. Composite manhole covers need to be made of cement, plastic, composite materials, etc. Since they are not recyclable, they can have anti-theft effects to a certain extent. However, due to the unsatisfactory matching between the manhole cover and the well ring, the heavy-duty vehicle often jumps up when it is run over, the reinforcement steel bar is seriously corroded, and it is easy to age in the outdoor en...

AI Technical Summary

Problems solved by technology

However, due to the unsatisfactory matching between the manhole cover and the well ring, the heavy-duty vehicle often jumps up when it is run over, the reinforcement steel bar is seriously corroded, and it is easy to age in the outdoor environment, especially the service life is only three to five years, and the relative price is too high

[0005] 2. Manhole covers made of cast iron materials are said to be because cast manhole covers have recycling value and are often stolen by people, leaving the well without a cover, which has a negative social impact

[0007] The disadvantage of the prior art is that most of the existing manhole covers are made of cast iron materials, and the cast iron materials have a certain recovery value, and the manhole covers are often stolen. Once the manhole covers are stolen, the wells will be uncovered This will bring serious safety hazards to pedestrians and vehicles.
