High-precision temperature sensing cable detection equipment

Abstract

The invention discloses high-precision temperature sensing cable detection equipment in the technical field of cable detection. The high-precision temperature sensing cable detection equipment comprises a rack, first moving tables are symmetrically connected to the left and right of the top of the rack in a sliding mode, and cable tensioning mechanisms are symmetrically connected to the left and right of the top of the rack in a sliding mode. By arranging two closable heating bins, omnibearing heating of a temperature sensing cable is achieved, the temperature sensing cable can rapidly reach adesignated temperature, meanwhile, uniform heating can be kept, and the detection efficiency is improved. A tensioning rack is arranged to drive a tensioning gear and a tensioning cam to rotate, so that the tensioning cam does not extrude a tensioning plate any more, a compressed second reset spring is reset, the temperature sensing cable is flexibly straightened, the temperature sensing cable isstraightened in the middle of the heating bin, the problem of uneven heating caused by bending is avoided, the temperature sensing cable is flexibly straightened so that the temperature sensing cableis not damaged, and the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to the technical field of cable detection, in particular to a high-precision temperature-sensing cable detection device. Background technique [0002] Inside the temperature-sensitive cable are two elastic steel wires, and each steel wire is covered with a layer of temperature-sensitive and insulating material. Under normal monitoring conditions, the two steel wires are in an insulated state. When the ambient temperature rises to the predetermined operating temperature, the temperature-sensitive The material breaks, and the two steel wires produce a short circuit, and the input module generates an alarm after detecting the short circuit signal. It can be used in power stations, substations, cable trenches, tunnels, interlayers, conveyor belts and other places. The temperature-sensing cable detector is stable and reliable, and is suitable for fire detection in harsh environments. [0003] In the invention case of a high-precision ...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of high-precision temperature-sensing cable detection equipment, to solve the problem that the current detection of the temperature-sensing cable in the above-mentioned background technology is to roast the middle section of the temperature-sensing cable, thereby detecting the quality of the temperature-sensing cable Good or bad, on the one hand, the temperature-sensing cable is easy to be heated unevenly during heating, and the temperature on the upper and lower sides will be different, which cannot quickly reach the predetermined temperature, and the detection efficiency is low. On the other hand, the length of the temperature-sensing cable intercepted during detection is slightly deviated. , it cannot be straightened when fixed, and the detection results of the temperature-sensing cable will be biased in the bent state
