As shown in Figure 1, the utility model relates to a kind of microtubule 100 for optical fiber that blows, and comprising: pipeline 110, and described pipeline 110 limits the pipeline space S1 passing through for optical cable; And elongated traction element 120, the whole described pipeline space S1 of extend through, for drawing optical cable 200 (Fig. 2) into microtubule 100.Elongated traction element 120 can be traction rope or drawing bar, and its end can be connected with the reinforcement 230 in optical cable 200, so that optical cable is drawn in microtubule 100.
Alternatively, described pipeline 110 comprises oversheath pipe layer 111 and Kev trombone slide layer 112, and described Kev trombone slide layer 112 engages with the internal face of external sheath layer 111.Kev trombone slide layer 112 is closed back and is combined for some strands of Kevs, can provide excellent pull resistance and anti-deformation nature for microtubule.
Further alternatively, described pipeline 110 also comprises lubrication management layer 113, and described lubrication management layer 113 is for optical cable 200 is by greasy property is provided, and engages with the internal face of Kev trombone slide layer 112.The internal face contacting with described optical cable of described lubrication management layer 113 can be provided with silicon core layer.So, when air-blowing or traction, can provide good lubricity so that optical cable passes through for optical cable.
General fire-retardant, low cigarette, the not halogen-containing material of adopting of described oversheath pipe layer can not produce toxic gas when burning.Overcoat pillar can be made by high-density polyethylene plastics, under the resistant to elevated temperatures condition of needs, can be made by crosslinked polyethylene plastic.
When manufacturing above-mentioned microtubule, can be when manufacturing described pipeline by described elongated traction element in advance in described pipeline.Can adopt any by the elongated traction element method in described pipeline in advance.For example, can first provide elongated traction element, the described elongated traction element of then substantially take is longitudinal axis, along described elongated traction element, progressively forms the pipeline around described elongated traction element.Also can be after pipeline have been got well in manufacture, more elongated traction element is incorporated in pipeline.
The utility model also relates to a kind of optical cable 200, and it is suitable for coordinating with the elongated traction element 120 in microtubule 100.Referring to Fig. 2, optical cable 200 comprises: optical fiber 210; Cable outer sheath 220, arranges to form optical fiber spatial accommodation S2 around optical fiber 210; And reinforcement 230, be arranged in described spatial accommodation S2, be suitable for being connected with the end of elongated traction element 120 in above-mentioned microtubule 100 with by described elongated traction element 120 tractions.
Reinforcement 230 not only can, for whole optical cable provides excellent physical strength, also coordinate as tow attachment with the elongated traction element in microtubule.
Optical fiber 210 can be multi-core fiber, as 12 core fibres and 24 core fibres.
When there is high temperature resistant requirement, cable outer sheath 220 also can be made by crosslinked polyethylene plastic.
As shown in Figure 2, optical cable 200 can also comprise that at least one Kev draws strand 240, is arranged in described spatial accommodation S2.Kev draws strand 240 reinforcement 230 and the end of elongated traction element 120 to be linked together by winding.In addition, Kev draws strand 240 can also strengthen the bulk strength of optical cable.
At needs when being blown into optical cable 200 in microtubule 100, first can link together one end of the reinforcement 230 of the end of the elongated traction element 120 in microtubule 100 and optical cable 200 (for example, by the mode of binding), then can utilize pressurized air to blow optical cable 200, particularly, utilize pressure gas that optical cable 200 is blown into and coordinates external force to the draw of elongated traction element 120 so that optical cable 200 is through to the other end of described microtubule from one end of described microtubule 100 from one end of described microtubule 100.Interior when mobile at microtubule 100 at optical cable 200, elongated traction element 120 shifts out gradually from microtubule 100.In other words, in optical cable 200 is arranged into microtubule 100 after, elongated traction element 120 also exits completely in microtubule, now, the described elongated traction element 120 that and described reinforcement that expose from described microtubule 100 are connected removes.
When the end of elongate traction element 120 and one end of reinforcement 230, the in the situation that of existing Kev to draw strand 240 in optical cable 200, can use this Kev to draw strand 240 to be wound around the end of elongated traction element 120 and one end of reinforcement 230.
In addition, when needs replacing has been blown into the optical cable 200 in microtubule, reinforcement 230 in optical cable in reinforcement in other optical cable 230 and microtubule (for example can be linked together, by binding), one end of reinforcement of optical cable and one end of the reinforcement of optical cable to be blown into of being about to be positioned at described microtubule link together.The in the situation that of existing Kev to draw strand 240 in optical cable 200, can utilize Kev to draw strand 240 to be wound around the end of two reinforcements.So, the optical cable that is positioned at microtubule plays the effect of above-mentioned elongated traction element.Afterwards, utilize pressure gas that described the first optical cable is blown into and coordinates external force to the draw of the second optical cable so that the first optical cable is through to the other end of described microtubule from one end of described microtubule from one end of described microtubule.After this, described the second optical cable reinforcement with described the first optical cable exposing from described microtubule being connected removes.
In the utility model, while there is no optical cable in microtubule, owing to there being elongated traction element, so, even if the microtubule of laying apart from very long or existence bending, also can utilize the draw of elongated traction element and guarantee that optical cable passes through microtubule smoothly when being blown into optical cable.In addition, while being blown into above-mentioned optical cable in microtubule, in the situation that needs are changed optical cable, owing to being provided with reinforcement in optical cable, so can utilize connection between the reinforcement of two optical cables to make the optical cable that exists in microtubule as the traction element of the other optical cable in microtubule to be blown into, thereby even the microtubule of laying distance is very long or have bending, also can when being blown into optical cable, utilizes the draw of the optical cable having existed in microtubule and guarantee that the optical cable blowing passes through microtubule smoothly.
Although disclose the exemplary embodiment that combines principle of the present utility model above, the utility model is not limited to the disclosed embodiments.On the contrary, the application is intended to use rule of the present utility model to cover any variation of the present utility model, purposes or modification.And, the utility model intention contain depart from present disclosure, as fallen under the utility model this content within the scope of the known or usual practice in field.
