Description

A kind of city intelligent safety manhole cover Technical field

The invention relates to the technical field of municipal facilities, in particular to an urban intelligent safety manhole cover.

Background technique

The process of urbanization is accelerating, and the construction of municipal public facilities is developing rapidly. Among them, the manhole covers have the characteristics of large number, wide distribution and difficult supervision. The damage and loss of the manhole cover have a great impact on the safety of vehicles and pedestrians and social stability. The loss of the manhole cover makes the road a "trap", which is even more dangerous at night or on rainy days. Especially in the rainy season, when there is stagnant water, sometimes the sewers are flooded, and the wellhead is hidden under the stagnant water. It is not easy to detect. It is extremely dangerous. If bicycles or electric vehicles encounter vehicle damage, the vehicle will also damage the chassis.

technical problem

The manhole covers currently used by the municipal government often do not have the prompt function. They can only rely on citizens who have found "traps" to place reminders on the damaged or missing manhole covers to remind passers-by and traffic to pay attention to safety. However, this method is not very smart. No one found out in time, and the accident cannot be effectively avoided. Therefore, how to provide an urban smart safety manhole cover with a safety prompt function is an urgent problem for those skilled in the art to solve.

Buoyancy mechanisms of different sizes are suitable for areas with different levels of stagnant water, which increases the applicability of general applications.

Preferably, a number of the barrier devices are evenly distributed on the inner wall of the manhole cover support pipe. The uniformly distributed feature can ensure that the roadblock device can provide prompt functions from multiple directions.

Preferably, the number of the fixing seats is the same as the number of the roadblock devices, and each roadblock device is connected to the corresponding fixing seat through the corresponding elastic device.

Beneficial effect

The road barrier device of the present invention is divided into a raising mechanism and a buoyancy mechanism, which can effectively prompt pedestrians to detour when the manhole cover is lost or damaged, and can play its prompting role regardless of whether there is water on the road surface. When the manhole cover is misplaced or lost, the lifting mechanism is lifted on the road surface by the action of the elastic device, acting as a roadblock. When there is water on the road surface, the buoyancy mechanism will be affected by the buoyancy of the water and float on the surface of the water, playing a reminder . The invention can effectively avoid accidents and is very suitable for the popularization of municipal manhole covers.
