Problems solved by technology

[0002] In urban planning, launching into the water is a factor that must be considered. However, due to the imperfect design of the manhole covers of many sewer wells, the manhole covers can be easily lifted, resulting in theft of the manhole covers, serious traffic accidents, and even casualties; When the rain is too heavy, it is necessary to open the manhole cover in many places to increase the drainage rate. The existing manhole cover is mostly unprotected when it is opened, and it is easy for people traveling to see that the manhole cover is removed and it will fall into the sewer well, causing personnel injuries. casualties

Abstract

The invention relates to the technical field of urban planning supplies, in particular to a sewer manhole cover, which comprises a cover body, rotating hinges, a pedestal, a barrier, a chain lock and circular rings, wherein the cover body is connected with the pedestal through the rotating hinges; the circular rings are welded on the upper part of the cover body; the barrier penetrate through the circular rings; one end of the chain lock is welded on the pedestal. According to the sewer manhole cover, a barrier design is adopted, so that the barrier can be effectively isolated at a manhole to prevent people from being swept into a sewer by rainwater when the cover body is required to be opened in heavy raining weather; when the manhole cover is opened, the manhole cover is in a standing state, so that pedestrians can be effectively warned and prevented from carelessly falling into the sewer; the manhole cover can also be effectively prevented from being stolen.
