Description

Longitudinal watertight cable for ships

Technical Field

The utility model relates to a marine cable.

Background

The prior art discloses the announcement number as: CN 203787190U, bulletin date 2014.08.20, comprises a cable core, wherein the cable core is formed by stranding a plurality of insulated wire cores; a filling layer is arranged at the gap of the cable core, a low-smoke halogen-free isolation belt is wound outside the cable core, and a low-smoke halogen-free flame-retardant rubber sheath is extruded outside the low-smoke halogen-free isolation belt; the insulated wire core is composed of a conductor and a high-resistance thin insulating layer extruded outside the conductor. The utility model has the advantages of softness, tear resistance, salt spray resistance, acid and alkali resistance, tensile strength and the like; the diameter of the copper wire adopted by the conductor is smaller, and the cable made of the copper wire has better flexibility. The utility model discloses an insulation and sheath adopt two kinds of different materials, combine the advantage of rubber and plastics together organically, have solved the problem that compliance and light in weight can not compromise, are applicable to the environment that uses on the ocean. However, the cable has poor water-blocking effect, can only meet the situation of low water pressure, and cannot meet the requirement of air tightness.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a naval vessel is with vertical watertight cable, it is effectual to block water, can satisfy the high water pressure occasion, can satisfy airtight requirement simultaneously.

In order to achieve the above object, the utility model provides a naval vessel is with vertical watertight cable, including a plurality of sinle silks, the periphery of sinle silks is provided with blocks water around the band, block water and have sealed glue around packing between band and the sinle silks, block water and be provided with the inner sheath around the periphery of band, the periphery of inner sheath is provided with the enhancement layer, the periphery of enhancement layer is provided with the oversheath.

Compared with the prior art, the beneficial effects of the utility model reside in that, sinle silk periphery parcel blocks water around the band, blocks water around the band in, packs sealed glue among the gap between the sinle silk, the effect of blocking water of improvement cable that can be very big satisfies the requirement of gas tightness and water proofness to inner sheath and oversheath can promote the corrosion resisting property of cable, and the enhancement layer then can make the cable can bear bigger water pressure, and it is effectual to block water, can satisfy high water pressure occasion, can satisfy airtight requirement simultaneously, the utility model discloses can be used to the marine power consumption.

As a further improvement, the sinle silk includes the conductor of 7 copper wire transposition, the periphery of conductor is provided with the insulating layer, it has the resin to fill between insulating layer and the conductor, fills vertically in the gap between the conductor like this and carries out the shutoff for the sinle silk can bear bigger water pressure and the promotion that the gas tightness can be higher.

As the utility model discloses a further improvement, the insulating layer is high density polyethylene insulation sheath, can further promote the insulating properties of sinle silk like this, can also make the sinle silk possess acid and alkali-resistance performance simultaneously, uses under water better.

As a further improvement, the enhancement layer is the steel wire weaving layer, can provide higher intensity for the cable can bear bigger water pressure, can use under deeper water, but also can bear bigger horizontal pulling force.

As a further improvement, the inner sheath is linear medium density polyethylene sheath, can further promote the corrosion resisting property of cable, and electrical insulation.

As a further improvement of the utility model, the outer sheath is a polyurethane sheath, so that the cable has better stability. Chemical resistance, rebound resilience and mechanical property, difficult compression deformation, low water absorption and further improvement of the water tightness of the cable.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The cable comprises an outer sheath 1, a reinforcing layer 2, an inner sheath 3, a water-blocking wrapping tape 4, sealant 5, a conductor 6, resin 7 and an insulating layer 8.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the longitudinal watertight cable for ships comprises a plurality of wire cores, wherein a water-blocking wrapping tape 4 is arranged on the periphery of each wire core, a sealant 5 is filled between each water-blocking wrapping tape 4 and each wire core, an inner sheath 3 is arranged on the periphery of each water-blocking wrapping tape 4, a reinforcing layer 2 is arranged on the periphery of each inner sheath 3, and an outer sheath 1 is arranged on the periphery of each reinforcing layer 2; the wire core comprises a conductor 6 formed by twisting 7 copper wires, an insulating layer 8 is arranged on the periphery of the conductor 6, and resin 7 is filled between the insulating layer 8 and the conductor 6; the insulating layer 8 is a high-density polyethylene insulating sheath; the reinforced layer 2 is a steel wire braided layer; the inner sheath 3 is a linear medium density polyethylene sheath; the outer sheath 1 is a polyurethane sheath.

The utility model discloses in, the gap between conductor 6 and the conductor 6 adopts resin 7 to fill, the gap between sinle silk and the sinle silk adopts sealed glue 5 to block up, the water pressure that not only bears is bigger, also reach airtight requirement, make the cable can still can normally work under 3 times pulling force bearing the dead weight through the steel wire weaving layer, and can be 400 meters under water uses, and can also satisfy the requirement to the water proofness, it is effectual to block water, can satisfy the high water pressure occasion, can satisfy airtight requirement simultaneously.
