After the tensile element is armored, a layer of high-intensity fiber materials is woven as a fastening layer which can lead close bonding between a tensile layer of the cable and an outer jacket; as water repellent treatment is respectively carried out in each processing procedure of the cable, each structure of the cable has no gaps, and the cable can bear a longitudinal and transverse water pressure of 6.0MPa, 2h without water leakage. As the tensile reinforcement element of the cable adopts the technique of bunch-stranded armored high-intensity fibers, the cable leads high tensile intensity, low specific gravity and small outer diameter.
Description
Technical field
The utility model relates to the novel rescue buoy system that is applied to undersea ship, is specifically related to warship rescue buoy cable.
Background technology
In the prior art, the rescue buoy system that is used for submarine adopts the J6P type warship cable wire signal cable of Zhang Zhiqing's production, this cable to adopt cable wire to strengthen more, and cable is harder, and heavier, has reduced the available buoyancy of buoy.In addition, this cable can not satisfy the requirement of direction waterproof, and the fail safe in the use can not guarantee.The primary structure figure of this cable as shown in Figure 1.11 for strengthening cable wire among the figure, generally adopts 84 * 0.3mm stainless steel wire stranded, plays tension and strengthen; 12 is conductor wire, and generally adopting 19 * 0.23 tinned wires is conductor, adopts rubber insulation; 13 is the rubber oversheath, generally adopts the neoprene sheath.
This construction of cable is simpler, and six cores are only arranged, and can only transmit simple control signal and low-power energy, can not transmit communications signals.The centre has adopted cable wire to strengthen element as tension, and the proportion that causes cable is big (nearly 1.8), and external diameter also reaches 20mm.In addition, this cable just can not satisfy the direction waterproof under the high hydraulic pressure in use in case oversheath is galled, and water can infiltrate into equipment along cable, makes the equipment fault that is short-circuited easily, can't satisfy actual needs.In addition, this cable tensile strength is low, and maximum only is 7kN, can not satisfy the requirement that the rescue buoy system discharges under deep diving.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel warship rescue buoy cable, can satisfy novel buoyage with the watertight of cable ability vertical, horizontal 4.5MPa require, can satisfy transmit communications signals and certain power electric energy simultaneously requirement, tensile strength height (connect back pull with connector and reach 1.5T), folding and unfolding fault-free repeatedly, satisfy cable proportion little (≤1.27), specification requirement that external diameter is little.
For solving the problems of the technologies described above, the utility model is to propose following technical scheme to realize:
A kind of novel warship rescue buoy cable mainly comprises conductor, tensile elements, oversheath; It is characterized in that: described conductor is arranged on cable center, is made of some power lines and some multiple twin line of symmetry symmetry is arranged; Described tensile elements is to be arranged on the outer tension enhancement layer of conductor, and described tension enhancement layer adopts armouring high tensile strength fibrous material structure.
Be woven with one deck high tensile strength fibrous material as fastened layer between described tension enhancement layer and the oversheath.
The tensile structure of armouring high tensile strength fibrous material can adopt restraints the configuration formula that tangles, and also can adopt the version of braiding, also the form that can adopt both to combine.
In all spaces such as twisted wire conductor, stranding, braiding, all insert the fluid sealant that blocks water, make whole cable seamless.
The utility model brings following beneficial effect:
This cable has all carried out the processing that blocks water in each road manufacturing procedure, make each structure tight of cable, confirms through test, adopts the cable of these PROCESS FOR TREATMENT can stand 6.0MPa, and the vertical, horizontal hydraulic pressure of 2h and not having leaks.
The tension of cable strengthens the technology that element has adopted the armouring high strength fibre, making cable percentage elongation when standing the pulling force of 15kN only is 3%, be significantly less than the percentage elongation of cable, the reliability of cable when use is stressed increased greatly with metal material and nonmetallic materials minimum 20%.And adopted high tensile strength fibrous material as tensile elements, the proportion of cable is also reduced greatly, maximum only is 1.27.
After the armouring tensile elements, braiding one deck high tensile strength fibrous material is as fastened layer, can make between the tensile layer of cable and the oversheath can cohere closely, and its interlayer slippage power maximum can reach 300N/30cm, is not easy to occur the phenomenon that heart yearn shrinks or stretches out.
