Intelligent cable shearing device

Abstract

The invention relates to an intelligent cable shearing device which can easily and accurately judge the cutting position of a cable and complete cutting. A pilot signal generating device and supporting plates are arranged at one end of the cable to be cut and at the two ends of a cable section respectively, and transmission of pilot signals is completed through the cable section. A conductive coating is arranged on the end face, close to one side of the cable, of each supporting plate, a communication cell can be electrically connected with external equipment through the conductive coatings, then a breakpoint detection device and a cable cutter are arranged on the cable section, and the breakpoint detection device is embedded in the cable cutter. The breakpoint detection device comprises asensor unit, the sensor unit is provided with a sensor coil, the sensor unit detects a magnetic field signal leaked to the outside from the cable and transmits the magnetic field signal to a controldevice of the cable cutter, and whether the cable cutter completes cutting work or not is judged through the control device of the cable cutter.

Description

technical field [0001] The invention relates to the field of cable cutting, in particular to an intelligent cable cutting device. Background technique [0002] Communication cables are usually several kilometers long and are usually buried underground. When a fault breaks in the cable and the faulty section needs to be removed, it is usually necessary to pull all the cables out of the ground and replace them as a whole. This practice causes huge waste And it wastes manpower and material resources, the work efficiency is low, and it is not easy to repair; another method is to use the pilot method to replace the cables in the harsh environment (such as acid-base zone, or frequent construction, frequent crustal movement, underground subsidence, etc.) Replace it directly, and this kind of replacement usually has a certain degree of accident, and it is not possible to accurately determine the fault point of the cable and complete the cutting. [0003] Usually, the cables are exp...

[0002] Communication cables are usually several kilometers long and are usually buried underground. When a fault breaks in the cable and the faulty section needs to be removed, it is usually necessary to pull all the cables out of the ground and replace them as a whole. This practice causes huge waste And it wastes manpower and material resources, the work efficiency is low, and it is not easy to repair; another method is to use the pilot method to replace the cables in the harsh environment (such as acid-base zone, or frequent construction, frequent crustal movement, underground subsidence, etc.) Directly replace it, and this kind of replacement usually has a certain degree of accident, and it is not possible to accurately determine the fault point of the cable and complete the cutting

[0003] Usually, the cables are exposed in the maintenance pit through excavation, and the maintenance personnel are also located in the maintenance pit to carry out the cable cutting operation. In the existing technology, the method of piloting and recording is used to cut one by one and identify and judge the failure. Whether the fault point of the cut cable is correct, there is a risk of wrong cutting in this way of operation
