Description

Technical Field

[0001] The utility model relates to the field of optical fibers, in particular to an active early warning optical fiber with segmented positioning. Background Art

[0002] Optical fiber refers to optical fiber, which is a fiber made of glass or plastic. Optical fiber can be used as a light transmission tool. The transmission principle is "total reflection of light". With the rapid development of communication technology, optical fiber communication technology has become the cornerstone of modern communications due to its advantages such as fast transmission speed, large capacity and strong anti-interference.

[0003] However, in special fields such as slope monitoring, the application of optical fiber still faces many challenges, such as the fiber optic wrapping mode, connector device, coupling method with the slope body, etc. The optical fiber used in slope monitoring is mostly segmented optical fiber. Segmented optical fiber means that multiple sections of optical fiber are connected through a fiber optic coupler. Segmented optical fiber has a wide range of applications.

[0004] However, when the existing segmented optical fiber is used, it is not convenient to actively warn the light segments with damaged points in the segmented optical fiber, and it is not conducive to monitoring the optical fibers in different segments. For example, when a damaged point appears in a certain section of the segmented optical fiber, it is necessary to check each section in the segmented optical fiber, which is not conducive to accurately locating the optical fiber segment with damaged points.

[0005] Therefore, we propose an active warning optical fiber with segmented positioning. Utility Model Content

For example, when a certain segment of the segmented optical fiber line 2 has a damage point, it is convenient to promptly discover the optical fiber line 2 with the damage point, and it helps to accurately locate the segment of the optical fiber line 2 with the damage point.

[0034] Among them, a matching notch is provided in the middle of the upper side of the inner ring surface of the protective tube 11 corresponding to the GPS chip 3, and a matching limiting groove 16 is provided in the middle of the lower side of the inner ring surface of the protective tube 11 corresponding to the signal transmitter 5, the GPS chip 3 is electrically connected to the signal transmitter 5, the optical fiber loss point identifier 4 is electrically connected to the signal transmitter 5, and the signal transmitter 5 is connected to an external signal receiver, and the limiting groove 16 on the protective tube 11 helps to limit the signal transmitter 5; matching retaining grooves 6 are provided in the middle of both ends of the optical fiber coupler body 1 corresponding to the internal threaded tube 8, and the outer ring surfaces of the internal threaded tube 8 are matched and fitted with the inner ring surfaces in the corresponding retaining grooves 6 on the optical fiber coupler body 1, and the retaining grooves 6 on the optical fiber coupler body 1 help to limit the internal threaded tube 8.

[0035] A fixing tube 7 is fixed on the inner side of the corresponding internal threaded tube 8 in the retention groove 6 on the main body 1 of the optical fiber coupler. The outer side of the fixing tube 7 is threadedly connected to the inner side of the corresponding internal threaded tube 8, and the fixing tube 7 can limit the threaded internal threaded tube 8; the connecting blocks 9 are located on the inner side of the corresponding end of the protective tube 11, and the outer annular surface of the connecting blocks 9 is matched and fitted with the inner annular surface of the corresponding position on the protective tube 11.

[0036] The edge portion of the surface of one side of the baffle 10 close to the protective tube 11 is located on the outside of the protective tube 11 and is fixed with a connecting tube 12.
