Description

technical field [0001] The invention relates to a road well cover, in particular to a road well cover safety protection washer device. Background technique [0002] The road well cover safety protection washer device is a protective device used to prevent passing pedestrians from falling into the well or driving car wheels from falling into the well due to the rupture and loss of the manhole cover. It is safe, durable, anti-aging, anti-noise, long service life, easy to obtain materials, and waste It has the advantages of being a treasure, easy to use, and has a warning function for maintenance. It can be used for traffic, road, municipal sewage, rainwater wells, tap water, power grids, telecommunications, military wells, etc. At present, the traditional road manhole cover protection devices only have manhole cover locks, electronic monitoring manhole covers, double manhole covers, and composite manhole covers instead of cast iron manhole covers. Protective devices and solut...

AI Technical Summary

Problems solved by technology

[0004] 1. Locking the manhole cover Due to the long-term wind and rain and the heavy pressure of the car, the lock is easy to rust and fail, and the key needs to be kept by a special person, which is very unscientific to use

[0005] 2. Electronic monitoring manhole covers are expensive and easy to damage, which is not conducive to popularization

[0006] 3. Composite manhole covers are as noisy and easy to break as cast iron covers. Although they have no recycling value, they are expensive to manufacture, and pedestrians and vehicles still have accidents after being broken or lost.

[0007] 4. The cost of double manhole covers is high, and it does not solve the fundamental problem if it is lost

[0008] 5. It takes 6-8 screws to fasten the nylon protective net in the well, which can prevent pedestrians from falling into the well, but it cannot prevent the wheels from collapsing, and the net needs to be opened when the well cover needs to be maintained. The work efficiency is very low, and it is only a temporary solution
