Abstract
The utility model relates to a cable, in particular to an over-water floating cable which comprises an outer insulation layer, an inner insulation layer and at least two cable core, wherein a waterproof layer is arranged between the outer insulation layer and the inner insulation layer, a fiber braid layer is arranged between the inner insulation layer and the cable cores, the outer insulation layer is formed by foam thermoplastic extrusion and is flat. As the technical proposal is adopted, the over-water floating cable can float on water surface, has the advantages of flexibility, good bending property, strong water resistance and ideal mechanical strength.
Description
Technical field
The utility model relates to cable, is specifically related to a kind of cable that can swim on the water surface.
Background technology
The engineering of operation on the water in the ocean, is normally carried out in the waters of rice up to a hundred and even thousands of meters, and this operation also needs to use the cable of transferring electric power except that necessary hardware facility such as equipment, instrument.Requirement for the cable that uses under this environment is often very harsh, there is following shortcoming in general common cable, on the one hand, owing to be operation on the water, for the insulating properties big city that guarantees cable increases the insulation number of plies of cable, like this cable will become very heavy; On the other hand, the cable that most of engineering equipments are used all can not swim in the water, and so cable is many more to what fall under water in the process that engineering equipment moves forward, increases the burden of mobile engineering equipment more, and is easy to cause coming off of cable two ends; Moreover cable is owed by water logging and makes its visibility reduce greatly, is easy to when dragging by damages such as biology in the water or rocks, but also can't observes damaged condition timely.
Therefore be badly in need of a kind of can swim in waterborne, flexibility good, and mechanical strength ideal, cable that block-water performance is good are carried out operation at sea.
The utility model content
The purpose of this utility model is, a kind of floating on water surface cable is provided, and solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The floating on water surface cable, comprise external insulation layer, inner insulating layer, cable core, it is characterized in that, be provided with water blocking layer between described external insulation layer and the inner insulating layer, also be provided with the fibrage layer between described inner insulating layer and the cable core, described cable core has two at least, and described external insulation layer is one deck external insulation layer that the foamed thermoplastic body extrudes, and becomes flat.
Thermoplastic elastomer has favorable chemical resistance and environmental resistance, destroys seldom water absorption that the serviceability temperature scope is wide, low and low gas release amount under ozone and UV-irradiation.External insulation layer can float on the water surface for the foamed thermoplastic body makes floating on water surface cable proportion diminish, and has further increased the insulating properties of cable.
Described water blocking layer adopts polyester twining package tape or nonwoven fabrics, effectively prevents the cable core of water intrusion to the floating on water surface cable.
The composite material that described inner insulating layer adopts rubber and polyvinyl chloride to constitute, described composite material not only has high flexibility, also has characteristics such as water-fast and wear-resisting simultaneously.
The fibrage layer that it is fiber that described fibrage layer can adopt cotton synthetic fibre silk, adopt cotton synthetic fibre silk both to increase the mechanical strength of flexible cable, can also make flexible cable quite soft, has the high ventilation performance, described fibrage layer also can adopt the fibrage layer of diamagnetic metallic fiber braiding, makes it have the advantage of protection and electromagnetic shielding.Cable core evenly is arranged in the fibrage layer closely, the protection cable core wearing and tearing and make moist.
Described cable core comprises the insulation sheath of inner wire and inner wire outer wrapping.Described insulation sheath can adopt polyolefin or polyvinyl chloride.Described inner wire is by copper wire and spin the synthetic fibre skein silk and knit and form, and can adopt copper wire and spins synthetic fibre silk fine pith braiding structure strand and knit, and under the prerequisite that guarantees ampacity, this structure makes conductor have certain retractility and intensity, and it is good to have flexibility, and tensile strength is good, and is in light weight.Inner wire have respectively outward insulation sheath, fibrage layer, inner insulating layer, water blocking layer, external insulation layer protection, safe and reliable to the protection of cable core inner wire, can prevent the seawater invasion and attack, and mechanical strength ideal.
The whole profile of described floating on water surface cable is a flat, swims on the water surface, makes the staff to see intuitively, the moving more convenient of operation at sea and connected engineering equipment, the unnecessary damage that more can avoid cable to flood in the water being brought.
Beneficial effect: owing to adopted technique scheme, advantage such as the utility model can swim in waterborne, has flexibility, good bandability, and block-water performance is strong, mechanical strength is desirable, can frequently move.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, the floating on water surface cable, comprise external insulation layer 1, inner insulating layer 3, cable core 5, be provided with water blocking layer 2 between external insulation layer 1 and the inner insulating layer 3, be provided with fibrage layer 4 between inner insulating layer 3 and the cable core 5, cable core 5 has two at least, with reference to Fig. 1, can select three cable cores closely and come in the fibrage layer 4, external insulation layer 1 is one deck external insulation layer that the foamed thermoplastic body extrudes, and becomes flat.
Thermoplastic elastomer has favorable chemical resistance and environmental resistance, destroys seldom water absorption that the serviceability temperature scope is wide, low and low gas release amount under ozone and UV-irradiation.External insulation layer 1 can float on the water surface for the foamed thermoplastic body makes floating on water surface cable proportion diminish, and has further increased the insulating properties of cable.
Water blocking layer 2 adopts polyester twining package tape or nonwoven fabrics, effectively prevents the cable core of water intrusion to the floating on water surface cable.The composite material that inner insulating layer 3 adopts rubber and polyvinyl chloride to constitute, composite material not only has high flexibility, also has characteristics such as water-fast and wear-resisting simultaneously.The fibrage layer that it is fiber that fibrage layer 4 can adopt cotton synthetic fibre silk, adopt cotton synthetic fibre silk both to increase the mechanical strength of flexible cable, can also make flexible cable quite soft, has the high ventilation performance, fibrage layer 4 also can adopt the fibrage layer of diamagnetic metallic fiber braiding, makes it have the advantage of protection and electromagnetic shielding.Cable core 5 evenly is arranged in fibrage layer 4 inner edge closely, the protection cable core 5 wearing and tearing and make moist.
