Description
technical field
The utility model relates to a kind of watertight towing load-bearing control cables, belongs to electric wire field.
Background technology
Along with scientific and technological development, watertight pull serial cable be under water with marine technology field in the middle of indispensable communication components and parts.When ocean is surveyed, undersea detection device often needs a umbilical cable to carry out reliable signal with lash ship to be connected and mechanical connection in actual use procedure, and this just needs a kind of watertight that can bear certain resistance to tension with direction waterproof performance to pull bearing cable.Watertight towing bearing cable has good resistance to environmental suitability, can block water, tensile strength is large, can use up to a hundred times in alternating bending folding and unfolding under small-bend radius.It should guarantee to provide under normal condition the reliability of electric power transfer and control signal transmission, guarantees again the safety of undersea detection device under accident situation.The development of watertight towing load-bearing control cables has solved has that watertight requires and electric power transfer and control and the communications problem of certain weight capacity, meets the actual needs in dark undersea detection field.
Utility model content
The utility model patent is to provide a kind of watertight towing load-bearing control cables, successfully solved the problem of load-bearing trailing cable direction waterproof deficiency under light water, make cable there is excellent watertightness, under certain hydraulic condition, can normally keep the reliability of electric power transfer and control signal transmission, and there is higher strength-weight ratio, flexural property, good corrosion-resistant, wear-resistant and folding and unfolding ability repeatedly flexibly.
Scheme of the present utility model is as follows: watertight towing load-bearing control cables, comprise the copper conductor being formed by some strands of copper wire bunchys, described copper conductor applies sealing glue outward and forms sealant I, described sealant I extrudes the elastic body insulated layer of TPV outward and forms insulated wire cores, when insulation core wire twisted synthesizing cable, with the gap that the glue that blocks water tamps between heart yearn, form water blocking layer, the wrapped band that blocks water outside stranding cable core, at the wrapped band that blocks water, be wound around armouring aramid fiber tension enhancement layer outward, the wrapped band I that blocks water outside aramid fiber tension enhancement layer, in the wrapped band I that blocks water, extrude polyurethane inner sheath outward, at inner sheath external application tin annealed copper wire woven shield coating sealing glue, form sealant II, sealant II extrudes polyurethane oversheath outward.
Further, the insulation thickness of the elastic body insulated layer of described TPV is 0.8～2.4mm.
Further, the jacket thickness of described polyurethane inner sheath is 1.3～2.5mm.
Further, the jacket thickness 2.0～3.5mm of described polyurethane oversheath.
The beneficial effects of the utility model:
1, good direction waterproof: watertight towing load-bearing control cables is by the improvement to the common encapsulant that blocks water, in material water-proof material, insert crosslinking sodium polyacrylate salt, can imbibition after meeting water, form gel, thereby guaranteed the reliability of cable direction waterproof performance.In the situation that cable is surprisingly broken, by these treatment measures that block water, can guarantee cable anhydrous oozing out under the hydraulic pressure of 4.5MPa, ensure the fail safe of underwater units.
2, good flexibility and resistance to bend(ing): cable has fully taken into account flexibility in design process, so all adopt the pitch of little lay ratio to carry out stranded at conductor on stranded and laying up pitch, the lay ratio of conductor is controlled between 10～12 times, cable core twisting pitch is controlled between 10～13 times of lay ratios, and adopt new TP V elastomer as insulation and polyurethane as sheath, effectively improved pliability and the resistance to bend(ing) of cable, made cable folding and unfolding use repeatedly.
3, bearing is good: watertight towing load-bearing control cables adopts and is wound around aramid fiber as tension enhancement layer, a kind of novel high-tech synthetic fibers, there is superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, lightweight, insulation, the advantage such as anti-aging, adopt aramid fiber to effectively raise watertight towing load-bearing control cables bearing as reinforced layer, improve anti-rupture pull force, and reduced whole cable quality.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Watertight towing load-bearing control cables, comprise the copper conductor 1 being formed by some strands of copper wire bunchys, the outer coating sealing of described copper conductor 1 glue forms sealant I 2, the outer elastic body insulated layer 3 of TPV that extrudes of described sealant I 2 forms insulated wire cores, when insulation core wire twisted synthesizing cable, with the gap that the glue that blocks water tamps between heart yearn, form water blocking layer 4, the wrapped band 5 that blocks water outside stranding cable core, at the wrapped outer winding armouring of the band 5 aramid fiber tension enhancement layer 6 that blocks water, in the outer wrapped band I 7 that blocks water of aramid fiber tension enhancement layer 6, outside the wrapped band I 7 that blocks water, extrude polyurethane inner sheath 8, at inner sheath 8 external application tin annealed copper wire woven shields 9 coating sealing glue, form sealant II 10, the outer polyurethane oversheath 11 that extrudes of sealant II 10.
The insulation thickness of the elastic body insulated layer 3 of described TPV is 0.8～2.4mm.The jacket thickness of described polyurethane inner sheath 8 is 1.3～2.5mm.Jacket thickness 2.0～the 3.5mm of described polyurethane oversheath 11.
