Based on the above situation, the distributed optical fiber pipeline safety monitoring system was born.

[0003] However, it still has the following disadvantages in actual use:

[0004] When using the existing distributed fiber optic pipeline safety monitoring system, the optical cable needs to be passed through the pipeline. Since the optical cable will be exposed to water pressure inside the pipeline and leak, the optical cable will be damaged after long-term use. In addition, when the optical cable is passed through, the optical attenuation and waveform of the optical cable may be affected for a certain period of time. Utility Model Content

[0005] The purpose of the utility model is to provide a distributed optical fiber pipeline safety monitoring system cable threading component to solve the problem proposed in the above background technology that the existing distributed optical fiber pipeline safety monitoring system needs to pass the optical cable through the inside of the pipeline when in use. Since the optical cable will be subjected to water pressure inside the pipeline and leak, the optical cable will be damaged when used for a long time, and the optical cable may be affected by the optical attenuation and waveform of the optical cable within a certain period of time when being threaded.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0011] Furthermore, the support mechanism further includes a base;

[0012] The connecting pipe is fixedly connected to the top position of the base.

[0013] Furthermore, the cable threading mechanism also includes an internally threaded ball valve, a ball valve handle, a waterproof joint, a cap and an optical cable;

[0014] The internal thread ball valve is fixedly connected to the top of the conduit, the ball valve handle is movably connected to the outside of the internal thread ball valve, the waterproof joint is fixedly connected to the top of the internal thread ball valve, the cap is fixedly connected to the top of the waterproof joint, and the optical cable is placed in the central position inside the pipe.

[0015] Furthermore, the optical cable passes through the connecting pipe and extends upward, and a water pipe is welded to the outer end of the connecting pipe.

[0016] Furthermore, the hexagonal bolts extend downward through the flange, and the hexagonal bolts are located around the outer ends of the flange and the blind flange.

[0017] Furthermore, the conduit and the connecting pipe are in a vertically collinear state, and the optical cable passes through the cover cap and extends upward.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] The utility model can effectively seal the connecting pipe and the conduit by arranging a fixed flange, a gasket and a blind flange between the connecting pipe and the conduit, and can prevent water from entering the conduit from the outside of the cap by using an internal thread ball valve and a waterproof joint, thereby increasing the waterproofness of the optical cable without affecting the light attenuation and waveform of the optical cable.
