Abstract
The invention discloses a stranded type corrosion-resistant wear-resistant optical cable protection pipe which is characterized in that the overall protection pipe which can bended for mutual fastening is twisted by special-shaped lines with Z-shaped or inverse Z-shaped cross section for protecting laying construction of optical cables and wear-easy local complex districts of sea bottom. The invention has the advantages of obviously reducing the cost of the optical cables, decreasing joints of the optical cables and improving the operation reliability of the optical cables.
Description
Technical field
The present invention relates to the safeguard measure to optical cable, cable and optoelectronic composite cable, promptly stranded formula anticorrosive wear-resistant decreases the optical cable protection tube.
Background technology
The optical cable of prior art or cable can both use in normal operation, but in special area and location, easily go wrong, the optical cable and the cable that for example are operated in the seabed run into through some coarse hard sea beds, the complex regions such as trench that steepness is very big through regular meeting, outer jacket quick-wearing very under seawater surge breaks down the whole piece circuit even breaks cable; When the horizontal drilling cable laying operation of non-excavation, optical cable and protective coverings of cable relate to through can't stand the powerful resistance that time drags tractive in boring and laying with ditch or with pipe with oil and gas pipeline that the mechanical performance gap is excessive to make outer jacket heavy wear.In order to increase the resistance to wear of cable, a kind of way is the overstriking armouring wire, but the result has strengthened the diameter and the weight of cable, the transmission performance of deterioration cable, and cost greatly increases; Another kind of way is that the outer whole process of cable extrudes and thickens oversheath, extrusion process is carried out continuously, whole process thickens, increased cost meaninglessly, only the complex region section is extruded and thicken oversheath, then each section increases by two optical cable joints, has reduced the reliability of omnidistance circuit, more than two kinds of methods all undesirable.
Summary of the invention
In order to overcome existing optical cable decreases performance at complex work section anticorrosive wear-resistant deficiency; the invention provides a kind of stranded formula anticorrosive wear-resistant and decrease the optical cable protection tube; easily optical cable is operated in complicated partial section and strengthens its anticorrosive wear-resistant damage performance; can significantly reduce the cost of cable; reduce joint, improve the reliable working operation of optical cable.
The present invention solves the technical scheme that its technical problem takes: a kind of stranded formula anticorrosive wear-resistant decreases the optical cable protection tube, by shape of cross section is that Z-shaped special-shaped line, anti-Z-shaped special-shaped line, interior reinforcement and outer reinforcement are formed, and it is characterized in that by shape of cross section being that Z-shaped special-shaped line or anti-Z-shaped special-shaped line strand are made the Global Macros pipe; The above-mentioned Z-shaped special-shaped line and the shape of cross section of anti-Z-shaped special-shaped line are that inside and outside perimeter line is that curved line, sides adjacent sideline are that the special-shaped tenon of shape complementarity is connected with a joggle inside and outside S shape or the anti-S shape, the special-shaped line radical of each layer strand layer is 〉=2 positive integer, being shaped as after stranded is tubular, and its shape of cross section is complete annular; Above-mentioned special-shaped line is by metal or nonmetally draw, pull out, squeeze, be rolled into, special-shaped line for non-metal wire the time be provided with axially in the line in reinforcement, line is outside equipped with outer reinforcement; Above-mentioned special-shaped line and the special-shaped line of interior reinforcement is arranged and the number of plies of outer reinforcement strand layer is individual layer, two-layer or multilayer.
Good effect of the present invention is can be according to on-the-spot actual needs, add the outside that is stranded in local complex section optical cable, cable or optical cable outer jacket, the tension and the anticorrosive wear-resistant that improve optical cable decrease intensity, significantly reduce the optical cable cost, reduce the optical cable joint, improve the optical cable reliability of operation.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1～Fig. 6 is the version cross-sectional view of sub-fraction optical cable protection tube of the present invention.
In Fig. 1～Fig. 6: 1. shape of cross section is Z-shaped special-shaped twisted wire, and 2. cross sectional form is anti-Z-shaped special-shaped twisted wire, 3. interior reinforcement, 4. outer reinforcement.
Embodiment
In Fig. 1～Fig. 6, a kind of stranded formula anticorrosive wear-resistant decreases the optical cable protection tube, by shape of cross section is that Z-shaped special-shaped twisted wire (1), shape of cross section formed for anti-Z-shaped special-shaped twisted wire (2), interior reinforcement (3) and outer reinforcement (4), it is characterized in that by shape of cross section being that Z-shaped special-shaped line (1) or shape of cross section made protection tube flexible, that fasten mutually for anti-Z-shaped special-shaped line strand; The shape of cross section of above-mentioned special-shaped line (1,2) is that inside and outside perimeter line is that concentric arcs, sides adjacent sideline are that the special-shaped tenon of shape complementarity is connected with a joggle inside and outside S shape or the anti-S type, the radical of the special-shaped twisted wire of each layer is 〉=2 positive integer, being shaped as after this abnormal shape line is stranded is tubular, and its shape of cross section is complete annular; Above-mentioned special-shaped line is by metal or nonmetally draw, pull out, squeeze, be rolled into, special-shaped line for non-metal wire the time be provided with axially in the line in reinforcement, line is outside equipped with outer reinforcement (4); The number of plies of above-mentioned special-shaped line (1,2) and outer reinforcement (4) strand layer is individual layer, two-layer or multilayer.
Embodiment 5; a kind of stranded formula anticorrosive wear-resistant decreases the optical cable protection tube; Fig. 5 is the optical cable protection tube by the two-layer special-shaped line strand system that interior reinforcement is arranged, and has than high-tensile and is used to have the complex section protection of the submarine fiber cable of heavy wear hazardous location, and is respond well.
Embodiment 6, and a kind of stranded formula anticorrosive wear-resistant decreases the optical cable protection tube, and Fig. 6 is by the optical cable protection tube of Z-shaped special-shaped line (1) and anti-Z-shaped special-shaped line and (4) three layers of strand system of outer reinforcement, and optical cable is had good tension, the protection of anticorrosive wear-resistant damage.
The foregoing description is the very little part of conception plans of the present invention; according to special-shaped line radical and the strand number of plies what; can also permutation and combination change the execution mode that many kinds of versions and equivalence; too numerous to mention; all in the protection scheme scope of the present invention's design, needn't repeat one by one at this.
