Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a temperature-sensing optical cable for pipelines, which effectively solves the problem that the exposed cable core of the temperature-sensing optical cable on the market is easily damaged by corrosion and has a short service life. The exposed cable core will also be pulled and the unexposed cable core will also be pulled out. The use effect is poor, and the overall compression resistance cannot be better, and the cable core is easily damaged due to excessive pressure.

Abstract

The invention provides a temperature sensing optical cable for a pipeline. The temperature sensing optical cable comprises a leather sheath and a cable core, the cable core is arranged in the leather sheath, pressure-bearing balls are annularly distributed outside the leather sheath, retention pipes are fixed outside the pressure-bearing balls, reinforcing mechanisms are arranged outside the retention pipes, positioning grooves are formed outside the retention pipes, elastic positioning balls are installed in inner cavities of the positioning grooves, assembling rods are fixed outside the positioning balls, an annular closed pipe is fixed at one end of each assembling rod, a shaping block is fixed at the head end of each closed pipe, and a shaping groove matching the shaping block is formed in the tail end of the closed pipe; an adjustable length telescopic tube is arranged on the side of the leather sheath in each closed pipe, a supporting rod is fixed to the surface of each closed pipe, a reset spring is installed at one end of each supporting rod, and an elastic block is installed at the end, located on the side face of a reset spring, of the supporting rod. The optical cable has the advantages that the cable core is not exposed after being cut, shielding protection can be performed, the service life is long, the cable is not easy to pull out, the use effect is good, integral compression resistance can be performed, and the compression of the cable core is small.

Description

technical field [0001] The invention belongs to the technical field of optical cables, in particular to a temperature-sensitive optical cable for pipelines. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable formed by an optical fiber...
