Description

Technical Field

[0001] This utility model relates to the field of heating pipeline monitoring technology, specifically to a dual optical cable synchronous traction cabling device for a fiber optic monitoring system of a heating pipeline, which is suitable for the installation of optical cable cabling in a fiber optic monitoring system, and is especially suitable for automated cabling operations in dual-pipe heating pipelines. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of energy demand, the safety and reliability of long-distance heating pipelines, as an important component of urban infrastructure, are receiving increasing attention. Fiber optic monitoring systems are primarily used in heating pipelines for real-time monitoring of pipeline leaks, temperature changes, and structural integrity. By utilizing fiber optic sensors to achieve precise alarm functions, this system has become the mainstream technology for modern heating pipeline monitoring. This system lays optical cables on the outer wall of the pipeline, utilizing the distributed sensing characteristics of optical fibers to detect abnormal temperatures, thereby promptly identifying potential leaks and preventing major accidents.

[0003] Traditional fiber optic cable laying methods primarily rely on manual labor, securing the fiber optic cable to heating pipes using stainless steel cable ties. While simple, this method has several significant drawbacks. First, it results in a long construction period. Since heating pipe networks often extend for kilometers or even tens of kilometers, manual laying requires a large workforce to tie the cables segment by segment, especially in areas with dense pipes or confined spaces, leading to low efficiency and extended overall construction time. Second, stainless steel cable ties are expensive and prone to rusting or loosening during use, increasing maintenance costs. Simultaneously, high labor costs, especially in high-risk working environments requiring specialized construction teams, further drive up expenses. Third, gaps exist between the fiber optic cable and the pipes. This binding method cannot ensure a tight contact between the cable and the pipes, leading to increased monitoring errors. Since fiber optic sensing relies on thermal conduction and mechanical coupling with the pipes, gaps interfere with signal accuracy, reducing system sensitivity and reliability. Furthermore, in some heating pipe network designs, the fiber optic cable needs to be installed between two parallel heating pipes in confined spaces, making manual operation difficult and increasing installation difficulty and safety risks. Meanwhile, the uninstalled optical cables are heavy and not easy to move or transport. They are also prone to damage at the construction site, which can further affect system performance.

[0004] While existing technologies offer some auxiliary cabling tools, such as simple pulling devices or single-fiber optic cable laying machines, most of these devices are designed for single-pipe installations and cannot achieve simultaneous dual-pipe cabling. Furthermore, they still require significant manual intervention and cannot achieve full automation. In addition, existing devices do not consider fiber optic cable protection mechanisms, leaving the cables exposed and vulnerable to environmental factors such as dust and mechanical damage. To address these issues, there is an urgent need for a high-efficiency, automated, and low-cost fiber optic cable cabling device to meet the requirements of modern heating network fiber optic monitoring systems. This device should be able to achieve simultaneous pulling and cabling of two fiber optic cables, ensuring close contact between the cables and the pipes, improving monitoring accuracy, while shortening the construction period and reducing costs.
