Description

Novel torsion-resistant zero-buoyancy cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to a novel torsion-resistant zero buoyancy cable.

Background

The zero-buoyancy cable means that the density of the cable is the same as that of water, so that the gravity of the cable is offset from the buoyancy borne by the cable, and the operation of equipment connected with the cable is facilitated. However, the zero-buoyancy cable in the prior art has poor torsion resistance, and the long-term torsion can cause the outer skin of the cable to be damaged, so that the cable cannot normally work, and the service life of the cable is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming of the poor anti-torsion performance existing in the prior art and providing a novel anti-torsion zero-buoyancy cable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel resistant zero buoyancy cable that twists reverse, includes the protective layer, the inboard fixed connection elastic layer of protective layer, the inboard fixed connection of elastic layer has the toughness layer, the inboard fixed connection parcel layer of toughness layer, parcel in situ side is provided with many cable cores, the outside parcel of cable core has the insulating layer, the parcel in situ is filled with elastic filling layer, the fixed haulage rope that bonds of elastic filling layer inner circle.

Preferably, the protective layer comprises a waterproof layer, an inner ring of the waterproof layer is fixedly bonded with a penetration-proof layer, and an inner ring of the penetration-proof layer is fixedly bonded with a heat insulation layer.

Preferably, the cable core is made of copper wires.

Preferably, the thickness of the protective layer is one quarter of the total cable thickness.

Preferably, the thickness ratio of the elastic layer to the flexible layer is 1: 1.

the utility model provides a novel resistant zero buoyancy cable that twists reverse, beneficial effect lies in: through the design on elastic layer and toughness layer, strengthened the elasticity and the toughness of cable, prevent that the cable from twisting when folding, causing the epidermis to appear the damaged condition, strengthened the resistant commentaries on classics nature of cable, be favorable to prolonging the life of cable.

Drawings

Fig. 1 is a schematic structural view of a novel torsion-resistant zero-buoyancy cable provided by the present invention;

fig. 2 is the structural schematic diagram of the novel torsion-resistant zero-buoyancy cable protective layer provided by the utility model.

In the figure: the cable comprises a protective layer 1, an insulating layer 2, an elastic layer 3, a toughness layer 4, a cable core 5, a traction rope 6, a wrapping layer 7, an elastic filling layer 8, a penetration-proof layer 9, a waterproof layer 10 and a heat-insulating layer 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1, a novel torsion-resistant zero-buoyancy cable, including protective layer 1, protective layer 1 thickness accounts for the fourth of total cable thickness, and the inboard fixed connection elastic layer 3 of protective layer 1, the inboard fixed connection of elastic layer 3 have toughness layer 4, and elastic layer 3 is 1 with the thickness ratio on toughness layer 4: 1, elastic layer 3 is made for the nitrile rubber material, and toughness layer 4 is made by acrylonitrile-butadiene-styrene copolymer, has strengthened cable elasticity through elastic layer 3's design, so that carry out the bending folding to the cable, through toughness layer 4's design, has strengthened the toughness of cable, prevents that the cable from receiving external force and the condition of breaking occur, thereby has strengthened the resistant ability of turning round of cable, prevents that the cable from taking place the damage, is favorable to prolonging the life of cable.

The inboard fixed connection parcel layer 7 on toughness layer 4, 7 inboards on parcel layer are provided with many cable cores 5, cable core 5 is made for the copper wire, the outside parcel of cable core 5 has insulating layer 2, parcel layer 7 is polytetrafluoroethylene material with insulating layer 2 and makes, play insulating effect to the cable, pack elastic filling layer 8 in parcel layer 7, elastic filling layer 8 material is made for cis-butadiene rubber, play the effect of packing between to cable core 5 through elastic filling layer 8, play fixed effect to

cable core

5, 8 inner circles of elastic filling layer are fixed to be bonded and have haulage rope 6, haulage rope 6's design, be favorable to the tensile ability of reinforcing cable.

Example 2

Referring to fig. 1-2, as the utility model discloses a further preferred embodiment, the difference with embodiment 1 lies in, protective layer 1 includes waterproof layer 10, waterproof layer 10 is made for the PVC material, waterproof layer 10 inner circle is fixed to be bonded has penetration-proof layer 9, penetration-proof layer 9 is that ABS material and PVC material mix to make, penetration-proof layer 9 inner circle is fixed to be bonded has thermal-insulated layer 11, thermal-insulated layer 11 is made for the rock wool fibre, penetration-proof layer 9's design, the intensity of epidermis has been strengthened, prevent that the cable from being punctureed by hard thing, thermal-insulated layer 11's design, play the effect of thermal-insulated to the temperature, prevent expend with heat and contract with cold, cause the damage along with the cable is inside.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
