Anti-theft monitoring equipment for backflow cable

Abstract

The invention relates to anti-theft monitoring equipment for a backflow cable. The equipment comprises the backflow cable and a wiring terminal. The wiring terminal is arranged at the backflow cable. The backflow cable anti-theft monitoring equipment further comprises a rotating protection mechanism. The rotating protection mechanism comprises a metal box, a driving motor, a driving bevel gear, linkage bevel gears, an annular guide rail, laser induction switches and a protection steel wire. The metal box is fixedly connected to the backflow cable. The driving motor is fixedly connected to the metal box. The driving bevel gear is fixedly connected to the main shaft end of the driving motor. The annular guide rail is fixedly connected to the metal box. The linkage bevel gear is rotationally connected to the annular guide rail. The driving bevel gear is meshed with the linkage bevel gears. The laser induction switches are distributed around the metal box at equal intervals. Each laser sensing switch is electrically connected with the driving motor. The protection steel wire is connected between the linkage bevel gears. The equipment has the beneficial effects that the backflow cable can be conveniently protected, and the backflow cable is prevented from being stolen.

Description

technical field [0001] The invention relates to the technical field of cable backflow cables, in particular to anti-theft monitoring equipment for backflow cables. Background technique [0002] The return cable is a low-impedance single-core insulated conductor laid in parallel along the cable line and grounded at both ends. When a ground fault occurs, the induced voltage on the return line forms a reverse ground current with the earth as the loop, offsetting most of the fault current flux in the conductor, so that the induced voltage on the adjacent communication and signal cables is significantly reduced. In general, when the return cable is installed, its two ends are fixedly connected to the corresponding positions only by the terminals. Some criminals are easy to use pliers and other utensils to cut off or damage the end of the return cable, thereby stealing the return cable, and the return cable itself does not have the anti-theft function, so it is easy to lose and c...
