Description
Technical Field
The invention belongs to the technical field of fire safety, and particularly relates to a device and a method for processing an on-off type detection line with a notch.
Background
Fig. 1 is a schematic diagram of a conventional on-off type probe line structure. As shown in fig. 1, in the field of fire fighting, the on-off type detection line 1 is wound and fixed on the outer wall of a fire-fighting gas cylinder, and the micro tensile plastic deformation occurring on the fire-fighting gas cylinder can be transmitted to the on-off type detection line 1 in time, so that the on-off type detection line 1 also generates tensile micro deformation, because the plasticity of the on-off type detection line 1 is low, the local plastic tensile deformation occurring on the outer wall of the fire-fighting gas cylinder can cause the on-off type detection line 1 to break before the fire-fighting gas cylinder bursts, and meanwhile, the monitoring box 2 connected with two ends of the on-off type detection line 1 for detecting the on-off state of the on-off type detection line 1 immediately gives an alarm signal after detecting that a loop of the on-off type detection line 1 is broken. However, the on-off detection line 1 has the disadvantages of low alarm sensitivity, difficulty in material selection during manufacturing, small application range, reduced alarm sensitivity when the temperature of the use environment rises, low stability and the like.
Chinese patent No. 201711293128.1 discloses a notched on-off type probe wire, and as shown in fig. 2, the notched on-off type probe wire 4 is made by providing a plurality of notches 3 in the length direction of a probe wire base material on a metal or nonmetal conductive wire as the probe wire base material, so that the cross-sectional area of the notches 3 on the on-off type probe wire 4 is smaller than the original cross-sectional area of the probe wire base material at the positions of the notches 3, and the pitch between the adjacent notches 3 is L. The on-off type detection line 4 has the advantages of high alarm sensitivity, easy manufacturing and material selection, wide application range, increased ambient temperature and less alarm sensitivity reduction caused by long-term work.
Theoretically, the notch 3 on the on-off type detection line 4 with the notch can be formed by adopting the modes including electric spark carving, grinding tool polishing, laser marking or laser carving, roller knurling, roller pressing and local medicament corrosion, and tests show that the laser marking or laser carving mode has the advantages of high manufacturing efficiency, low cost, corrosion resistance and the like. However, the laser marking machine hardly ensures the stability of the elongation of the whole on-off type detection line 4 after the notch 3 is arranged due to the diversity of performance parameters.
