Problems solved by technology

[0003] In recent years, the problem of urban water accumulation in the rainy season has been very serious. When the underground pipes are turned upwards, the manhole cover is easily lifted by the water. At this time, it is difficult to be found because the wellhead is submerged in sewage, which puts pedestrians and vehicles in greater danger.

Abstract

The invention discloses a well cover with open protecting and warning function belonging to the technical field of water conservancy project, according to the technical solution, the well cover comprises a well ring fixed on a wellhead, a well cover and a safe net, the ring surface of the inner side of the well ring is provided with an annular element rest being coaxial with the well ring, the lower part of the inner side of the well ring is provided with a plurality of safe net hanging rings evenly distributed along the circumference; the outer edge of the well cover presses on the element rest at the inner side of the well ring and one side of the well cover is hinged to the well ring; the safe net is circular and is provided with a plurality of hooks along the circumference and the hooks match with the safe net hanging rings on the well ring. According to the well cover, the safe net and a plurality of well cover open protecting and warning devices are formed based on the traditional well cover, the invention can effectively prevent that the passer or article falls into the well no matter the opening reason for the well cover and send the warning information for the passers and vehicles by a variety of ways.

Description

technical field [0001] The invention relates to a well cover which can effectively prevent pedestrians from falling into a well, and belongs to the technical field of water conservancy engineering. Background technique [0002] As a metal product, city manhole covers are often lost in large quantities, and pedestrians fall into wells and vehicles are damaged due to this, which seriously threatens people's travel safety. [0003] In recent years, the problem of water accumulation in cities during the rainy season has been very serious. When the underground pipelines are turned upwards, the well covers are easily lifted by the water. At this time, the wellhead is submerged in sewage and it is difficult to be found, which puts pedestrians and vehicles in greater danger. [0004] Therefore, how to eliminate the threat caused by lack of urban manhole covers to pedestrians and vehicles and ensure people's travel safety has always been a difficult problem faced by relevant departme...
