Anti-theft method for well cover and anti-theft well cover therewith

Abstract

The invention relates to a method for guarding the well cover and relative anti-theft well cover, belonging to city fitting device technique, while the invention has simple structure, and easy operation. The invention comprises a well cover and a well base, wherein, the well base comprises a horizontal well base ring and an inner wall vertical to the inner circumference of well base ring. It is characterized in that: the well cover and the well base utilize two-point or three-point connection of cylinder pins; the well base has electromagnetic anti-theft lock which has at least on cylinder pin as bolt; it uses electromagnetic iron to connect the control device to control the movement of said bolt; the external power has a decode controller; and the electromagnetic anti-theft lock can start the movement of bolt when the decode controller is connected and its encode signal meets the anti-theft code. In said invention, the power control signal is encode signal which can solve the anti-theft problem.

Description

Technical field [0001] The invention relates to an anti-theft manhole cover used in an anti-theft method for road drainage wells, maintenance wells, etc., and belongs to the technical field of road matching devices. Background technique [0002] The underground pipeline system is an important part of the urban infrastructure, which is responsible for the discharge of sewage, the transportation of gas, and the laying of underground communication cables. Many of the pipelines need to be laid underground along urban roads. In order to carry out the dredging and maintenance of the pipelines, many vertical shafts are set up above the pipelines, which are covered by manhole covers that can be opened. There are a large number of manhole covers and a wide distribution area. However, the current serious loss of pipeline manhole covers in cities has not only caused major economic losses to the country, but also after the loss of road manhole covers, the exposed manholes often cause injurie...

AI Technical Summary

Problems solved by technology

However, the loss of pipeline manhole covers in cities is serious at present, which not only causes great economic losses to the country, but also exposes well holes that often cause damage to passing vehicles and pedestrians after road manhole covers are lost, directly threatening the safety of people's lives and property. The loss of manhole covers has already become a public nuisance in the city
