Auxiliary safety device for inspection well

Abstract

The invention discloses an auxiliary safety device for an inspection well. The auxiliary safety device for the inspection well mainly comprises a suspension ring, springs and a color flag. The suspension ring is made of light closed-mouth foam, the red-yellow ring is attached under a well lid, the springs are symmetrically arranged compression springs with consistent parameters, one end of each ofthe compression springs is fixed with the suspension ring, the other end of the well lid is fixed on a wall of an inspection well, and the springs are compressed by self weight of the well lid by 30-40 cm and are kept in a stable state; and the color flag is connected to the suspension ring by a 20 cm long nylon wire. After the well lid is separated from a well mouth, the suspension ring body isreleased by the springs, so that a driver can conveniently recognize a hole-hole roadblock.

Description

technical field [0001] The invention relates to an auxiliary safety device for inspection wells, in particular to a device for improving safety by prompting and warning after the inspection shaft cover is opened on the road. Background technique [0002] In cities with a lot of rain, the rainwater often collects on the road too quickly after a heavy rain, causing road accumulation and causing travel difficulties such as cars breaking down. In order to quickly remove the accumulated water on the road surface, the well cover will be opened to expand the discharge diameter; this will cause eddies and potholes on the road surface, which will easily cause passers-by and vehicles to fall into the well pit. On the other hand, if the rainwater collects too quickly, especially when there is pressurized water in the pipeline and it is difficult to discharge, the manhole cover will be pushed away and discharged outward, which will also easily cause passers-by and vehicles to fall into ...

AI Technical Summary

Problems solved by technology

[0002] In cities with a lot of rain, the rainwater often collects on the road too quickly after a heavy rainstorm, causing water accumulation on the road, which makes it difficult for cars to break down and other travel difficulties

In order to quickly remove the accumulated water on the road surface, the well cover will be opened to expand the discharge diameter; this will cause eddies and potholes to appear on the road surface, which will easily cause passers-by and vehicles to fall into the well pit

On the other hand, if the rainwater collects too quickly, especially when there is pressurized water in the pipeline and it is difficult to discharge, the manhole cover will be pushed open and discharged, which will also easily cause passers-by and vehicles to fall into the well pit

In addition, there are also sporadic cases of manhole covers being stolen and sold, which may also lead to a sudden hole in the road surface, resulting in the fall of people and vehicles.

Some owners require mandatory anti-fall nets, which can only solve the fall of people or light objects, and cannot guarantee the fall of vehicles.
