Anti-drop manhole cover device for automatically adjusting drainage

Abstract

The invention discloses an anti-drop manhole cover device for automatically adjusting drainage. The device includes a mounting ring arranged at an upper port of a manhole channel, wherein the mountingring is internally provided with a lifting ring, the lifting ring is internally provided with a cover which can be opened, a bottom side edge of the lifting ring is uniformly provided with mounting rods, a bottom surface of the mounting ring is provided with suspension rods matched with the mounting rods, lower ends of the suspension rods are hinged with lower ends of the mounting rods through levers, a water collection basin is arranged below the cover, the water collection basin is arranged on a supporting ring, the edge of the supporting ring is uniformly provided with poles matched with the mounting rods in quantity, ends of the poles are hinged with tail ends of the levers through connection rods, and a bottom surface of the water collection basin is distributed with water holes. Thedevice is advantaged in that the size of drainage gaps can be automatically adjusted according to the road area water condition, that the road area water is discharged into a sewer in time is guaranteed, opening the manhole cover is not needed, pedestrians are effectively prevented from falling into well holes, safety is greatly improved, and functions are more powerful.

Description

technical field [0001] The invention belongs to the technical field of manhole covers, in particular to an anti-falling manhole cover device for automatically adjusting drainage. Background technique [0002] The traditional manhole cover in our country is a simple disc shape, which is directly covered on the sewer well. There are leaking holes on the manhole cover, which are used to guide the road surface water into the sewer well. Although this ordinary manhole cover can be applied to ordinary cities However, in the rainy weather in the south, many urban roads often generate a large amount of accumulated water. This kind of ordinary manhole cover cannot lead the accumulated water into the well in time, causing the accumulated water on the road to form a river. Therefore, road maintenance workers only The manhole cover can be lifted to allow the water on the road to rush directly into the sewer well, but after the manhole cover is lifted directly, it will make it very dangero...

[0002] The traditional manhole cover in our country is a simple disc shape, which is directly covered on the sewer well. There are leaking holes on the manhole cover, which are used to guide the road surface water into the sewer well. Although this ordinary manhole cover can be applied to ordinary cities However, in the rainy weather in the south, many urban roads often generate a large amount of accumulated water. This kind of ordinary manhole cover cannot lead the accumulated water into the well in time, causing the accumulated water on the road to form a river. Therefore, road maintenance workers only The manhole cover can be lifted to allow the water on the road to rush directly into the sewer well, but after the manhole cover is lifted directly, it will make it very dangerous for pedestrians to walk on the road. We can often see in TV news reports that due to the excessive water on the road, Pedestrians cannot see the road clearly and fall directly into the sewer without a manhole cover. This situation often occurs in areas with heavy rain and floods in southern my country, such as Shenzhen, Guangdong, Guangxi, Hunan and other areas
