Embodiment
Although fully describe the present invention with reference to the accompanying drawing containing preferred embodiment of the present invention, before this describes, should be appreciated that those of ordinary skill in the art can revise invention described herein, obtain technique effect of the present invention simultaneously.Therefore, Yan Weiyi discloses widely to those of ordinary skill in the art must to understand above description, and its content does not lie in restriction exemplary embodiment described in the invention.
As shown in Figure 1, the present invention relates to one and blow optical fiber microtubule 100, comprising: pipeline 110, described pipeline 110 limits the pipeline space S1 passed 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 be drawn in microtubule 100 by optical cable.
Alternatively, described pipeline 110 comprises oversheath tube 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 combined for some strands of Kevs are closed back, and can provide excellent pull resistance and anti-deformation nature for microtubule.
Further alternatively, described pipeline 110 also comprises lubrication tube layer 113, and described lubrication tube layer 113 for optical cable 200 is by providing greasy property, and engages with the internal face of Kev trombone slide layer 112.The internal face contacted with described optical cable of described lubrication tube layer 113 can be provided with silicon core layer.So, when air-blowing or traction, good lubricity can be provided so that optical cable passes through for optical cable.
Described oversheath tube layer generally adopts fire-retardant, low cigarette, not halogen-containing material, can not produce toxic gas when burning.Overcoat pillar can be made up of high-density polyethylene plastics, under the resistant to elevated temperatures condition of needs, can be made up of crosslinked polyethylene plastic.
When manufacturing above-mentioned microtubule, can when manufacturing described pipeline by described elongated traction element in advance in described pipeline.Can adopt any by the method for elongated traction element in advance in described pipeline.Such as, can first provide elongated traction element, then basic with described elongated traction element for longitudinal axis, progressively form the pipeline around described elongated traction element along described elongated traction element.Also after pipeline has been got well in manufacture, more elongated traction element can be incorporated in pipeline.
The present invention also relates to a kind of optical cable 200, it is suitable for coordinating with the elongated traction element 120 in microtubule 100.See Fig. 2, optical cable 200 comprises: optical fiber 210; Cable outer sheath 220, arranges to form fiber containment space S 2 around optical fiber 210; And reinforcement 230, be arranged in described spatial accommodation S2, be suitable for being connected to be drawn by described elongated traction element 120 with the end of the elongated traction element 120 in above-mentioned microtubule 100.
Reinforcement 230 not only can provide excellent physical strength for whole optical cable, also coordinates 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 up of crosslinked polyethylene plastic.
As shown in Figure 2, optical cable 200 can also comprise at least one Kev and draw strand 240, is arranged in described spatial accommodation S2.Kev draws strand 240 can be linked together by the end of reinforcement 230 with elongated traction element 120 by being wound around.In addition, Kev draws strand 240 can also strengthen the bulk strength of optical cable.
When needs are blown into optical cable 200 in microtubule 100, first one end of the end of the elongated traction element 120 in microtubule 100 and the reinforcement 230 of optical cable 200 can be linked together (mode such as by bundling), then pressurized air can be utilized to blow optical cable 200, particularly, utilize pressure gas to be blown into from one end of described microtubule 100 by optical cable 200 and coordinate external force to be through to the other end of described microtubule to make optical cable 200 from one end of described microtubule 100 to the draw of elongated traction element 120.When optical cable 200 is mobile in microtubule 100, elongated traction element 120 shifts out gradually from microtubule 100.In other words, after optical cable 200 is arranged in microtubule 100, elongated traction element 120 also exits completely in microtubule, now, the described elongated traction element 120 be connected with described reinforcement exposed is removed from described microtubule 100.
When one end of the end of elongate traction element 120 and reinforcement 230, in optical cable 200, there is Kev when drawing strand 240, this Kev can be used to draw strand 240 to be wound around the end of elongated traction element 120 and one end of reinforcement 230.
In addition, when needing to change the optical cable 200 be blown in microtubule, can the reinforcement 230 in other optical cable be linked together (such as with the reinforcement 230 in the optical cable in microtubule, by binding), be about to one end of the reinforcement of the optical cable being positioned at described microtubule and link together with one end of the reinforcement of optical cable to be blown into.In optical cable 200, there is Kev when drawing strand 240, Kev can be utilized to draw strand 240 to be wound around the end of two reinforcements.So, the optical cable being positioned at microtubule plays the effect of above-mentioned elongated traction element.Afterwards, utilize pressure gas to be blown into from one end of described microtubule by described first optical cable and coordinate external force to be through to the other end of described microtubule to make the first optical cable from one end of described microtubule to the draw of the second optical cable.After this, described second optical cable be connected with the reinforcement of described first optical cable exposed from described microtubule is removed.
In the present invention, when there is no optical cable in microtubule, owing to there is elongated traction element, so, even if the microtubule distance of laying is very long or there is bending, also can utilizes the draw of elongated traction element when being blown into optical cable and ensure that optical cable passes through microtubule smoothly.In addition, when being blown into above-mentioned optical cable in microtubule, when optical cable changed by needs, owing to being provided with reinforcement in optical cable, so the optical cable that the connection between the reinforcement of two optical cables can be utilized to make to exist in microtubule is as the traction element of the other optical cable in microtubule to be blown into, even if thus the microtubule distance of laying is very long or there is bending, also can utilize the draw of the optical cable existed in microtubule when being blown into optical cable and ensure that the optical cable blowed passes through microtubule smoothly.
Although be disclosed above the exemplary embodiment combining principle of the present invention, the present invention is being not limited to the disclosed embodiments.On the contrary, the application is intended to use rule of the present invention to cover any change of the present invention, purposes or amendment.And, the invention is intended to contain depart from present disclosure, as fallen into this content within the scope of the known or usual practice in field belonging to the present invention.
