Abnormal-motion detection unit for manhole cover

Abstract

The invention discloses an abnormal-motion detection unit for a manhole cover. The detection unit involves a shell, a microswitch, a first spring and a force transmission assembly, wherein the microswitch, the first spring and the force transfer assembly are arranged in the shell; the lower end of the force transfer assembly is arranged corresponding to a trigger head of the microswitch, and the upper end of the force transfer assembly is connected with the lower end of the first spring; and the first spring extends out of the shell, and the upper end of the first spring is used for abutting against the lower side of the manhole cover. The abnormal-motion detection unit can be suitable for different manhole covers and different scenes, and is simple in structure, stable in operation and long in service life.

Description

technical field [0001] The invention relates to an abnormal movement detection unit, in particular to an abnormal movement detection unit for a manhole cover. Background technique [0002] At present, in order to keep the urban environment clean and beautiful, it is not suitable to use the traditional exposed plug-in connector layout method for various cables. However, due to the increasing dependence of people on communication and electricity, higher requirements are put forward for related infrastructure. Therefore, it becomes an economical means to use the pipes of the underground drainage system for telecommunication laying. It can be seen that the management of pipelines is one of the key points in the current urban security field. At present, the problems caused by pipelines mainly include: First, pipeline resources are illegally occupied, and cables and facilities in pipelines are stolen and damaged from time to time. ; Second, the manhole cover is stolen or removed ...

Problems solved by technology

It can be seen that the management of pipelines is one of the key points in the current urban security field. At present, the problems caused by pipelines mainly include: First, pipeline resources are illegally occupied, and cables and facilities in pipelines are stolen and damaged from time to time. Second, the manhole cover was stolen or removed without being discovered in time, causing people and vehicles to fall into the well, causing casualties, etc.

Traditional manhole cover management usually uses manual inspection, but this method requires a lot of manpower and material resources, and is inefficient, which is difficult to meet the management of a large number of manhole covers in the city.
