Problems solved by technology

Modern tap water manhole covers can bear the pressure from top to bottom, and because of their own weight, they can generally maintain a stable position, but they have poor resistance to the impact of water flow from below the manhole cover, especially when the manhole cover has accumulations due to waterlogging. When the water is in the water, it is easier to be washed away by the water flow under the manhole cover, which greatly increases the danger of the road surface

Abstract

The invention discloses a self-locking anti-falling well cover, which comprises a well cover and a well cover seat. The well cover is placed on the well cover seat. There is a groove for accommodating the lock hook, the bottom of the groove is provided with a wedge-shaped protrusion, and the hook-shaped end of the lock hook is connected with the wedge-shaped protrusion; there are two wedge-shaped protrusions and the lock hook. This self-locking anti-off manhole cover has a good anti-off effect, is not easy to be washed away by the water flow under the manhole cover, and can increase the safety of the road surface when waterlogging occurs.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to a self-locking anti-falling well cover. Background technique [0002] In modern cities, waterlogging often occurs due to the large area of ​​hard ground. The urban pipeline maintenance manhole covers on the street are often washed away by the gushing water, and the wellhead cannot be seen by pedestrians and vehicles when the water overflows the street. The tragedy of stepping into a well and being washed away by the current. Modern tap water manhole covers can bear the pressure from top to bottom, and because of their own weight, they can generally maintain a stable position, but they have poor resistance to the impact of water flow from below the manhole cover, especially when the manhole cover has accumulations due to waterlogging. When there is water, it is easier to be washed away by the water flow under the manhole cover, which greatly increases the danger of the road s...
