A device for warning manhole cover dislocation

Abstract

The invention relates to a device for warning the dislocation of a well lid. The device comprises a first warning device 10 and a second warning device 10, wherein the first warning device comprises a spring case 3, a steel piece 4, a spring case fastener 5, a spring 6 and a first warning ball 7; a transverse penetrating hole is formed in the first warning ball 7 and a locking hole is formed in a position at the upper part of the spring case 3; and the second warning device 20 comprises a plurality of rubber bands 11, a plurality of second warning balls 12 and a container 13 for receiving the plurality of second warning balls. The device is simple in structure and high in reliability; the existing well lid does not need to be modified; besides, the device is capable of warning the dislocation of either the submersed well lid or the non-submersed well lid, and low in cost.

Description

technical field [0001] The invention relates to a device for warning the dislocation of a manhole cover, which belongs to the technical field of safety warning devices. Background technique [0002] Various manhole covers (such as sewage manhole covers, rainwater manhole covers and cable manhole covers, etc.) on the existing urban streets often have manhole cover dislocations (the dislocations include manhole covers that are translated, opened at a certain angle, lost or washed away, etc.) The way is out of the wellhead), which brings great potential safety hazards to the road traffic of pedestrians and vehicles. Especially at night, the possibility of accidents will be greater. How to avoid the occurrence of safety accidents caused by manhole cover dislocation and effectively remind people of the danger of manhole cover dislocation has become a major safety problem that needs to be solved urgently.

Problems solved by technology

[0002] Various manhole covers (such as sewage manhole covers, rainwater manhole covers and cable manhole covers, etc.) on the existing urban streets often have manhole cover dislocations (the dislocations include manhole covers that are translated, opened at a certain angle, lost or washed away, etc.) way out of the wellhead), which has brought great safety hazards to the road traffic of pedestrians and vehicles

Especially at night, the possibility of accidents will be greater. How to avoid safety accidents caused by manhole cover dislocation and effectively remind people of the danger of manhole cover dislocation has become a major safety problem that needs to be solved urgently

[0003] Moreover, when a heavy rainstorm occurs, the lower rainwater manhole cover will be overturned or lifted from the inside of the well in some cases. In the case of such a manhole cover dislocation, because the wellhead is submerged to a certain depth, the conventional warning device is likely to be affected by the height. too low to warn

This poses a major safety hazard to pedestrians and vehicles traveling in the rain

[0004] Moreover, the existing manhole cover dislocation warning device often needs to greatly improve the structure of the existing manhole cover. If this type of technical solution is applied, the manhole cover has to be replaced or a large and complicated improvement is made to the existing manhole cover. This makes the improvement and replacement The cost is very high, which brings great economic pressure to all the units of the manhole cover; although some do not change the existing manhole cover itself but only add warning devices under the existing manhole cover, its structure is either complicated in design or inconvenient to install and disassemble. Either it is easy to bring inconvenience to the workers' downhole maintenance, or the reliability of the warning is not high, and it is easy to cause false alarms and no alarms
