An anti-blocking manhole cover with automatic adjustment of drainage

Abstract

The invention discloses an anti-blocking well lid capable of automatically adjusting the amount of drainage. When the rainfall is relatively large, a large amount of accumulated water at a wellhead isdifficult to drain in a short time, garbage such as leaves and the like accumulated at the wellhead can directly cause the wellhead blockage, and the emergency is poor. The anti-blocking well lid comprises a lid body, wherein a total drainage hole is formed in the top of the lid body; the total drainage hole is internally provided with a cabin body; a plurality of first drainage holes are formedin the top surface of the cabin body; the bottom of the cabin body communicates with a plurality of water collecting tank bodies; a second drainage hole is formed in each of the water collecting tankbodies; a plurality of lifters are arranged at the bottom of the lid body; the water collecting tank bodies and the lifters are arranged one by one; each water collecting tank body drives the cabin body to reciprocate in the axial direction of the total drainage hole through the corresponding lifters; when the cabin body moves to a rising limit position, the outer wall of the cabin body is in close contact with the inner wall of the total drainage hole; and when the cabin body is in a descending state, a drainage channel is formed between the cabin body and the total drainage hole. The anti-blocking well lid is applied to urban groundwater pipelines.

Description

Technical field: [0001] The invention relates to a well cover, in particular to an anti-blocking well cover for automatically adjusting drainage. Background technique: [0002] my country is a country with frequent flood disasters. According to historical records, from 206 BC to 1949 AD, during the 2155 years since the founding of the People's Republic of China, there were 1029 major floods, almost once every two years. When large-scale floods occurred in the city, the passive drainage of manhole covers The process is difficult to deal with, and the emergency response is poor. It is difficult to discharge a large amount of accumulated water, which directly affects the travel of urban people and causes a large amount of economic losses. Now the role of urban groundwater pipelines is becoming more and more important. At present, the commonly used drainage manhole cover usually adopts the one-piece structure manhole cover, which can play a drainage role when the rainfall is s...

Problems solved by technology

At present, the commonly used drainage manhole cover usually adopts the one-piece structure manhole cover, which can play a drainage role when the rainfall is small. It is difficult to quickly drain away a large amount of accumulated water in a short period of time. Once it encounters garbage such as leaves accumulated at the wellhead with the water flow, it will be directly blocked and the drainage function will fail, resulting in a large amount of accumulated water around the drainage well and on the road surface, especially When the drainage well is set in a low-lying area such as an overpass, it is more likely to cause a large amount of water, which makes the traffic of passing vehicles inconvenient, and some vehicles may even be flooded and cause the engine to stall.
