Description

Technical Field

[0001] The utility model relates to a drainage manhole cover, in particular to a manhole cover with a large drainage volume that is easy to drain, and belongs to the technical field of municipal engineering. Background Art

[0002] Municipal sewage manhole covers are devices in municipal systems that are mainly used to cover and seal underground manholes, while allowing rainwater on the road to flow into the underground drainage system. The applicant has found that the prior art has at least the following technical problems: the drainage holes on existing municipal sewage manhole covers are small, and in the summer rainstorm season, due to heavy rainfall, rainwater is often blocked by accumulated debris, resulting in rainwater not being able to be discharged from the drainage holes into the ground in time, thus affecting traffic.

[0003] After searching, the Chinese patent with publication number CN109138133A discloses a municipal sewage manhole cover that can automatically increase the drainage volume, including a base, a top cover and a bottom cover. The bottom of the guide column is provided with a limited position boss, which can limit the position of the bottom of the spring. The beneficial effect is that when the rainfall is heavy, the bottom cover can be automatically opened to increase the drainage volume of the manhole cover, thereby avoiding serious water accumulation on the road surface; the structure is simple and safe to use.

[0004] Although the above scheme can increase the drainage capacity of the manhole cover, thereby avoiding serious water accumulation on the road, the municipal sewage manhole cover in the above patent does not have the function of filtering debris in the sewage. The manhole cover cannot filter and collect debris in the water when draining for a long time, which causes the manhole cover drainage device to be blocked; for this reason, we provide a large-discharge manhole cover that is easy to drain to solve the above problems.
