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.

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] A municipal anti-theft manhole cover, such as figure 1 with figure 2 As shown, it includes a base 1 and a cover 6 for covering the sewer. The cover 6 slides and fits with the boss of the base 1. The center of the cover 6 is provided with a number of water leakage holes 61 for drainage. The cover 6 is provided with a locking mechanism for locking the cover 6, and the boss of the base 1 is also provided with an opening assembly 7 located between the cover 6 and the base 1 for unlocking the locking mechanism.

[0033] It should be noted that, through the locking action of the locking mechani...

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...
