Embodiment Construction

[0019] Below in conjunction with the attached drawings ( figure 1 ) Describe the present invention.

[0020] figure 1 It is a schematic diagram of the structure of a thermal pipe with an optical cable for implementing the present invention. Such as figure 1 As shown, a thermal pipe with an optical cable includes a thermal pipe main body 2 and an outer structure layer 6 covering the outer peripheral surface of the thermal pipe main body 2, and an optical cable 1 is provided in the outer structure layer 6. The optical cable 1 extends along the axial direction of the outer structural layer 6. The optical cable 1 has a double-layer armor protection structure. The optical fiber in the optical cable 1 is a single-mode optical fiber. The outer structural layer 6 includes a thermal insulation coating 3, the inner surface of the thermal insulation coating 3 is in contact with the outer peripheral surface of the thermal pipe body 2, and the optical cable 1 is laid on the thermal insul...

Abstract

The invention provides a thermal pipeline with an optical cable. By laying the optical cable in an external structure layer of the thermal pipeline in the whole process, external signal change, such as abnormal temperature or structure disturbance, can be sensed by virtue of optical fibers in the optical cable, and sensors are continuously distributed on the thermal pipeline in the whole process,thereby facilitating monitoring of the thermal pipeline with no blind zone in the whole process in use; the safe and high-quality operation of a heat pipeline network is improved. The thermal pipelineis characterized by comprising a main body of the thermal pipeline, and the external structure layer wrapping the peripheral surface of the main body of the thermal pipeline; and the external structure layer is internally provided with the optical cable.

Description

Technical field [0001] The present invention relates to a thermal pipeline networking technology, in particular a thermal pipeline with an optical cable. By laying the optical cable in the outer structural layer of the thermal pipeline, the optical fiber in the optical cable can be sensitive to external signal changes, such as abnormal temperature or Structural disturbances, etc., form a continuous sensor distribution on the thermal pipeline throughout the entire process, which is beneficial to the realization of the full-process non-blind spot monitoring of the thermal pipeline in use, and promotes the safe operation and high-quality operation of the thermal pipeline network. Background technique [0002] Heating pipelines are the basic components that form the urban heating pipeline network. They are the heating pipelines from the heat source to the heating entrance of the building. The commonly used heating medium is hot water or steam. The inventor found that the existing the...
