Description

Technical Field

[0001] This invention belongs to the field of drainage device technology, and particularly relates to a municipal road drainage device with rapid drainage function. Background Technology

[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewage pipes". Municipal drainage pipes are widely used in urban roads, mainly to discharge rainwater into nearby rivers or sewage treatment plants, thereby greatly alleviating the traffic obstruction caused by road water accumulation.

[0003] Currently, drainage systems typically include drainage pipes and drainage manhole covers installed on the drainage pipes. When there is little water on the road, the water can enter the drainage pipes through the drainage manhole covers. When there is a lot of water on the road, it is difficult to drain the water quickly using the drainage holes on the drainage manhole covers. In this case, sanitation workers need to manually open the drainage manhole covers, which greatly increases the labor intensity of sanitation workers.

[0004] Based on this problem, Chinese invention patent CN113668665B discloses a rapid drainage system for highways. In this technology, the drainage manhole cover can automatically open or close according to the amount of rainfall, which can quickly drain a large amount of water from the road surface and greatly reduce the labor intensity of sanitation workers. However, when this drainage system opens the drainage manhole cover, it raises the cover upwards. This makes the manhole cover higher than the road surface. In rainy weather, when visibility is already obstructed, passing vehicles are prone to colliding with the drainage manhole cover, which may even cause traffic accidents, posing a great safety hazard. Summary of the Invention
