Reminder manhole cover

Abstract

The invention discloses an inspection-well cover with a warning function. The inspection-well cover comprises an inspection-well cover body and an inspection-well cover base matched with the inspection-well cover body. Pressure-sensitive sensors are arranged at the matching position of the inspection-well cover body and the inspection-well cover base. A light emitting body is arranged on the periphery, positioned on the inspection-well cover body, of the inspection-well cover base. A warning device made of expansion foam is arranged in the inspection-well cover base, is fixed in the inspection-well cover base through a pull rope and is sealed by a seal cover. The pressure-sensitive sensors detect existence of the inspection-well cover body, and the light emitting body on the periphery of the inspection-well cover is controlled to emit light to warn pedestrians in case of nonexistence of the inspection-well cover body; when water flow flowing out of a sewer washes away the inspection-well cover, the inspection-well cover washed way drives the pull rope to tear the seal cover sealing the warning device, and the warning device expands and floats to the liquid level after absorbing water to warn the pedestrians that the inspection-well cover is washed away, so that safety of the pedestrians is guaranteed.

Description

technical field [0001] The invention relates to a manhole cover. Background technique [0002] Manhole covers are an indispensable municipal facility on urban roads. At present, manhole covers are often stolen. However, existing manhole covers do not have the functions of timely alarming and prompting passers-by and vehicles to avoid when the manhole covers are stolen, which often causes pedestrians to fall. Injuries in the well, damage to vehicles, and even death in severe cases. In addition, for well-known reasons, more inspection manhole covers are stolen at night. Due to the dim light at night and the difficulty of observation, inspection wells without manhole covers pose a greater threat to passers-by and vehicles. In the event of casualties or vehicle damage, it is often difficult for the relevant departments to deal with the issue of responsibility and compensation, which has caused a great burden to the country and society.

[0002] Manhole covers are an indispensable municipal facility on urban roads. At present, manhole covers are often stolen. However, existing manhole covers do not have the functions of timely alarming and prompting passers-by and vehicles to avoid when the manhole covers are stolen, which often causes pedestrians to fall. Injuries in wells, vehicle damage, and even death in severe cases

In addition, for well-known reasons, more inspection manhole covers are stolen at night. Due to the dim light at night and difficult observation, inspection wells without manhole covers pose a greater threat to passers-by and vehicles.

In the event of casualties and vehicle damage, the relevant departments often face many difficulties in dealing with the issue of responsibility and compensation, which has caused a great burden to the country and society.

[0003] In addition, in areas where floods occur, the manhole cover is often washed away by the gushing water from the sewer. Since the manhole cover is submerged in the water at this time, it cannot be seen with the naked eye, and it is easy to cause pedestrians to fall into the manhole.
