Heating heat-preservation device of pipeline optical fiber casing

Abstract

The invention discloses a heating heat-preservation device of a pipeline optical fiber casing. The heating heat-preservation device consists of three heating heat-preservation units, wherein the heating heat-preservation unit in the middle is connected with the two left and right heating heat-preservation units through connection diverters respectively; each heating heat-preservation unit consists of a middle heating layer in the middle and a first protecting layer and a second protecting layer on and below the middle heating layer; the middle heating layer of the heating heat-preservation unit in the middle is connected with the middle heating layers of the two left and right heating heat-preservation units through connection leads respectively; a connecting end is arranged in the heating heat-preservation unit in the middle; the connecting end is connected with a temperature control device. As the three heating heat-preservation units and the connection diverters are adopted, when in use, the heating heat-preservation device can be very conveniently mounted and used by rotating the heating heat-preservation units according to demands, the three heating heat-preservation units form an equilateral triangle in a surrounding manner, then the optical fiber casing can be heated, the heat can be preserved, stable operation in winter can be ensured, and adverse effects caused by rain, snow and temperature drop can be avoided.

Description

technical field [0001] The invention belongs to the technical field of pipeline optical fiber laying, and more specifically relates to a heating and heat preservation device for a pipeline optical fiber sleeve. Background technique [0002] During the construction of existing projects, it is often necessary to lay pipelines for industrial water pipelines, farmland irrigation, factory water supply and drainage, and other fields. At present, the prestressed steel cylinder concrete pipe (PCCP) is usually used. In order to ensure the safe operation of the pipeline with it as the main structure, it is generally necessary to detect the broken wire and leak of the pipeline. Due to the needs of engineering practice, it is often necessary to realize real-time detection, and this kind of real-time monitoring often uses a distributed optical fiber detection system, that is, laying optical cables inside the pipeline, using optical fibers as sensors, and detecting broken wire signals alo...

Problems solved by technology

During on-site construction, it is often necessary to protect the optical fiber. Generally, a sleeve is used to place the optical fiber in the middle for protection. When it enters winter or rainy and snowy seasons, changes in the external temperature will often cause changes in the sleeve material, and further damage to the optical fiber. The optical fiber brings adverse effects, which in turn affects the entire detection process
