Municipal manhole cover device with water level sensor

Abstract

The invention discloses a municipal manhole cover device with a water level sensor. The municipal manhole cover device comprises a manhole cover sleeve body which is fixedly installed in a roadbed and communicates with a drainage channel, and a manhole cover body. The manhole cover body comprises a cast iron base part and concrete which is poured into a containing cavity in the upper end of the cast iron base part. A square through groove is formed in the center of the cast iron base part. Two sliding grooves are symmetrically formed in the lower end wall of the cast iron base part. Communicating grooves of the square through groove are formed in the inner side end walls of the two sliding grooves. The sliding grooves are internally provided with sliding blocks in a slideable mode. Linkage arms are installed in the communicating grooves in a sldeable mode. The linkage arms are fixedly connected with the inner side ends of the corresponding sliding blocks. An inner protruding ring is arranged inside the manhole cover sleeve body. An inner annular groove is formed in the manhole cover sleeve body and located above the inner protruding ring, and the inner side end of the inner annular groove is fixedly provided with an inner gear ring. The outer side ends of the sliding blocks are provided with limiting teeth engaged with the inner gear ring.

Description

technical field [0001] The invention relates to the field of municipal facilities, in particular to a municipal inspection well cover device with a water level sensor. Background technique [0002] In urban construction, a large number of pipelines are built under the road surface, such as low-level gas pipelines, tap water pipelines, power pipelines, and communication pipelines, and these pipelines need an outlet leading to the ground, and a manhole cover needs to be installed at the outlet so as not to affect driving. and vehicle traffic, so inspection manhole covers are one of the indispensable municipal facilities in urban construction. Most of the current inspection manhole covers are made of reinforced concrete materials, and when installed, they only rely on gravity and friction to maintain stability. The method is that when some cars pass by quickly, the manhole cover is prone to large vibrations. In severe cases, the manhole cover will move. If the entrance is not c...

[0002] In urban construction, a large number of pipelines are built under the road surface, such as low-level gas pipelines, tap water pipelines, power pipelines, and communication pipelines, and these pipelines need an outlet leading to the ground, and a manhole cover needs to be installed at the outlet so as not to affect driving. and vehicle traffic, so inspection manhole covers are one of the indispensable municipal facilities in urban construction. Most of the current inspection manhole covers are made of reinforced concrete materials, and when installed, they only rely on gravity and friction to maintain stability. The method is that when some cars pass by quickly, the manhole cover is prone to large vibrations. In severe cases, the manhole cover will move. If the entrance is not covered by the manhole cover, or if it is not reinstalled in time, pedestrians will often fall into the well and be injured. damage, and even cause death
