Technical field
The present invention relates to cable protection technical field, be specifically related to a kind of cable sheath tube.
Background technology
At present laying field at power transmission line is mainly that the pipeline that common plastic material is made adopts the mode of directly sunkening cord to carry out cabling, but the pipeline that common plastic material is made in the middle of practical application is easy to run into a lot of problems, such as:
1, the flexibility of conventional pipelines is poor is easy to cause pipeline break, and the rigidity of pipeline is low so that the weight bearing power of pipeline is very poor;
2, conventional pipelines is owing to adopting common plastic cement material to make, and its acid and alkali-resistance corrosion resistance is poor, is easily corroded, and affects the use of pipeline;
3, when excess Temperature or when too low, conventional pipelines is easy to occur quality problems, even fracture;
4, traditional pipeline radiation hardness, ageing resistace is bad, useful life is short, poor fire.
Be more than the some shortcomings of traditional pipeline, but be but easy to cause pipeline normally to use, more serious may damage cable, causes the fault of power transmission line, bring very large economic loss, traditional cable transfer pipeline can not meet the needs of modern social development.
Summary of the invention
Object of the present invention, for having solved above-mentioned existing technical disadvantages, the invention provides a kind of superior performance, the cable sheath tube of long service life.
For achieving the above object, the technical solution used in the present invention is: a kind of cable sheath tube, the interface end and the female end that include protecting pipe body, be connected with protecting pipe body, the skin that described protecting pipe body comprises endosexine and is composited with described endosexine one, described outer field thickness is more than or equal to the thickness of endosexine, described endosexine is PVC plastic layer or PE plastic layer or MPP plastic layer, and described skin is frp layer.
Preferably: described frp layer is entwined by glass fiber impregnated flame-retarded resin.
Preferably: in described interface end, be also equipped with at least one groove, described groove has been embedded in sealing ring; Described female end is that the protecting pipe one end that is arranged on made from this body by integral forming of protecting pipe has the extended pipeline of caliber.
Preferably: the position joining at described interface end and protecting pipe body is also provided with positive stop lug boss, and the external diameter of described positive stop lug boss is suitable with the external diameter of described female end.
Preferably: described outer field surface is also provided with reinforcing rib structure.
Preferably: described outer field surface is also coated with anti-aging or fire-retardant auxiliary agent.
Useful technique effect of the present invention is: in technical scheme of the present invention, by the skin of protecting pipe body being arranged to comprise endosexine and be composited with endosexine, the weight that the endosexine of PVC plastic layer or PE plastic layer or MPP plastic layer makes protecting pipe is lighter, increase useful life, acid and alkali-resistance corrosion resistance is strong, compound described skin is frp layer, described outer field thickness is more than or equal to the thickness of endosexine, weight bearing power is strong, there is lightweight, easily construction, good airproof performance, composite performance is stable, good flame resistance, the features such as long service life.

In figure: 1, protecting pipe body, 2, interface end, 3, female end, 4, endosexine, 5, skin, 6, sealing ring, 7, positive stop lug boss, 8, reinforcement.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 and Figure 2, as the first specific embodiment of the present invention.
A kind of cable sheath tube, the interface end 2 and the female end 3 that include protecting pipe body 1, be connected with protecting pipe body 1, the skin 5 that protecting pipe body 1 comprises endosexine 4 and is composited with endosexine 4 one, outer 5 thickness is more than or equal to the thickness of endosexine 4, endosexine 4 is PVC plastic layer or PE plastic layer or MPP plastic layer, adopting PVC plastic layer or PE plastic layer or MPP plastic layer is liner, cold-resistant, the heat resistance of protecting pipe are further improved, can use at-40 ℃～130 ℃ long-term, and acid-alkali-corrosive-resisting is strong; Outer 5 is frp layer, and frp layer is entwined by glass fiber impregnated flame-retarded resin, makes the inner wall smooth coefficient of friction of protecting pipe less, effectively prevents that the later stage from occurring from situations such as inner surface filoselle, stuck cables while use; Join between being also provided with for the protecting pipe positive stop lug boss 7 of time limit stationary interface end 2 and female end 3 positions of the position joining at interface end 2 and protecting pipe body 1, female end 3 is for to have the extended pipeline of caliber with the one-body molded protecting pipe one end that is arranged on of making of protecting pipe body 1; In interface end 2, be also equipped with at least one groove, the degree of depth of groove is less than the thickness of frp layer, in the present invention, preferred groove quantity is one, the rubber seal 6 being arranged in groove is arranged at the position near positive stop lug boss 7 in interface end 2, obviously, the quantity of groove can also be two, three etc., is embedded in rubber seal 6 for further strengthening the sealing after connecting between protecting pipe at groove; Positive stop lug boss 7 is made with protecting pipe body 1 is one-body molded, and the external diameter of the external diameter of positive stop lug boss 7 and female end 3 is suitable, and outer 5 surface is also provided with reinforcement 8 for further strengthening the rigidity of protecting pipe, makes the weight bearing power of protecting pipe stronger; Also be coated with anti-aging or fire-retardant auxiliary agent on outer 5 surface for preventing that protecting pipe is aging, further strengthen the fire resistance of protecting pipe, obviously anti-aging or fire-retardant auxiliary agent also can apply at the outer surface of female end 3; In the present invention, preferred auxiliary agent is carbon black, also can use other auxiliary agents, such as bromide etc., tubing still can normally be used in the open under environment; By contrast, the present invention is more superior than the properties of the general cable sheath tube on market, long service life, rigidity are more than the twice of plastic-coated steel, there is the advantages such as cost is low, Never-rusty, can be widely the cables such as urban network reconstruction, town road construction, electrified railway remodelling, expressway construction, optical cable, news cable lay protection in apply.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
