Description

Technical Field

[0001] The utility model relates to the technical field of rat-proof optical cables, in particular to a rat-proof optical cable with a triangular stretching body design. Background Art

[0002] Traditional rat-proof optical cables, such as those using glass yarn and capsaicin, are difficult to achieve the desired effect. The use of metal armored optical cables is costly, heavy, and difficult to construct. The terrain of optical cable construction is complex and the construction scenes are changeable. The tensile, torsion, and lateral pressure resistance of the optical cables directly affect the service life of the optical cables. Rapid fault inspection and positioning of optical cables constructed in complex environments is one of the important improvement issues in the subsequent maintenance of optical cable communications.

[0003] The application number is 202310709458.3, which discloses a rat-proof optical cable, which includes a cable core, an inner reinforcement element, an inner sheath, an inner friction reinforcement layer, an outer reinforcement element, an outer friction reinforcement layer and an outer sheath arranged in sequence from the inside to the outside along the radial direction of the rat-proof optical cable; the inner reinforcement element includes at least one inner reinforcement layer, and the twisting directions of adjacent inner reinforcement layers are opposite; the outer reinforcement element includes at least one outer reinforcement layer, and the twisting directions of adjacent outer reinforcement layers are opposite; in the outer reinforcement element, the outer reinforcement layer located on the outermost side is made of glass elements. The friction reinforcement layer is inserted into both sides of the outer reinforcement element, and the friction between the layers is increased by using the friction reinforcement layer to ensure that when the optical cable is subjected to force, the force value can be transmitted from the outer sheath inward, through the outer reinforcement element, the inner sheath, the inner reinforcement element to the cable core in sequence, so as to realize the layer-by-layer transmission of the force value, thereby solving the problem that the force value between the components of the mixed yarn structure optical cable in the related art cannot be effectively transmitted, and finally improving the overall mechanical properties of the optical cable.

[0004] However, there are some shortcomings. The rat-proof optical cable passes through the outer reinforcement element, inner sheath, inner reinforcement element to the cable core, realizing layer-by-layer transmission of force, thereby solving the problem that the force between the various layers of components of the mixed yarn structure optical cable in the related technology cannot be effectively transmitted, and ultimately improving the overall mechanical properties of the optical cable, but the device has poor rat-proof performance. Utility Model Content

[0005] The purpose of the utility model is to provide a rat-proof optical cable with a triangular tensile body design, so as to solve the problem proposed in the above background technology that the rat-proof optical cable passes through an outer reinforcement element, an inner sheath, and an inner reinforcement element to the cable core to achieve layer-by-layer transmission of force, thereby solving the problem in the related technology that the force between the various layers of components of the mixed yarn structure optical cable cannot be effectively transmitted, and ultimately improves the overall mechanical properties of the optical cable, but the device has poor rat-proof performance.

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

[0007] The utility model is a rat-proof optical cable with a triangular stretching body design, comprising a mold core, one side of the mold core is movably connected with a mold sleeve, the inner side of the mold sleeve is fixedly connected with an optical cable protection sleeve, the inner side of the mold sleeve is fixedly connected with a sleeve, the inner side of the mold sleeve is fixedly connected with an optical fiber communication unit, the inner side of the mold sleeve is fixedly connected with a fluorescent or color-changing material, the inner side of the mold sleeve is fixedly connected with a circular FRP rat-proof material, and the inner side of the mold sleeve is fixedly connected with a flat FRP rat-proof material.

[0008] Furthermore, the optical fiber communication unit is wrapped around by flat and round glass fiber reinforced plastic.

[0009] Furthermore, two circular FRP rodent-proof materials are symmetrically arranged.

[0010] Furthermore, two of the flat FRP rodent-proof materials are symmetrically arranged.

[0011] Furthermore, the circular FRP rodent-proof material and the flat FRP rodent-proof material are both arranged on the inner side of the optical cable protective sheath.

[0012] The utility model has the following beneficial effects:

[0013] (1) The optical fiber communication unit provided in the utility model is wrapped around by flat and circular glass fiber reinforced plastic (GFRP). The triangular wrapping saves raw materials and has a stable structure. Then, through the triangular design of the cable type, circular glass fiber reinforced plastic (GFRP) is arranged at the three corner ends to serve as auxiliary rodent-proof and tensile-resistant elements. The optical cable structure is a triangular tensile body design. Due to the stability of the triangle, the optical cable has very good torsion resistance and lateral pressure resistance. At the same time, the glass fiber reinforced plastic used for rodent prevention can play a tensile role. Therefore, the optical cable of this design has excellent tensile, compressive and torsion resistance. The circular reinforcement unit at three angles is also replaceable. For example, it can be replaced with a communication single-line copper cable, and the energized cable can be used. Finally, fluorescent or other color-changing reaction materials are sprayed on the surface of the circular and flat reinforcement members. When the outer sheath is damaged, the fault point can be quickly located through fluorescent reaction or other color-changing or color-developing reaction, and the outer sheath of the optical cable can be remedied or repaired in time to prevent the optical cable communication unit from being destroyed or damaged due to the failure to repair the outer sheath in time.
