Cable channel anti-theft device

Abstract

The invention relates to an anti-theft device for a cable channel. The anti-theft device comprises a manhole cover mounted at the opening part of the cable channel, wherein the manhole cover is formed by combining a plurality of cover plates, and a locking mechanism is arranged between the manhole cover and the inner wall of the cable channel; the locking mechanism comprises a fixed part fixedly arranged on the inner wall of the cable channel and moving parts arranged on the cover plates respectively, and the fixed part and the moving parts can be matched for locking; the moving parts are divided into two types including at least one active locking device and passive locking devices, the at least one active locking device can be operated outside the cable channel equipped with the cover plates so as to realize the locking or unlocking action, and each passive locking device realizes the locking or unlocking action only when the cover plate where the passive locking device is located is dismounted or mounted; the all cover plates arranged at one opening part of the cable channel comprise the at least one active locking device. The anti-theft device for the cable channel can be opened conditionally, so that the cable channel can be prevented from being opened at will, the conditions that a cable is stolen, the channel resource is occupied at will and the like are avoided, and the safety of electric power facilities is effectively protected.

Description

technical field [0001] The invention relates to an anti-theft device arranged at a cable channel, in particular to a cable channel manhole cover with an anti-theft function. Background technique [0002] With the development of the distribution network, the number of cables and their channels is increasing rapidly every year, and the management of cables and their channels has become an important basis for the maintenance, transformation, and emergency repair of power distribution equipment. However, the existing cable channel usually lacks an effective anti-theft function and can be opened at will. Therefore, the cable is often stolen and channel resources are arbitrarily occupied, which seriously affects the normal operation of the cable. Therefore, in order to better protect the power infrastructure, it is necessary to develop a cable channel anti-theft device that can reduce the incidence of the above-mentioned problems. Contents of the invention [0003] The object o...
