Description

Integral firecracker cable

Technical Field

The utility model relates to a marine seismic survey equipment field, in particular to whole big gun cable.

Background

The seismic cable is a connecting channel between an underwater marine seismic source and deck equipment and comprises a cable and a high-pressure air pipe. When the number of the seismic sources is small, a plurality of independent cables are generally connected with a plurality of independent air pipes and are wrapped by a sheath for protection, namely the split seismic cable. However, when the number of the seismic sources is large, the number of the cables and the number of the air pipes are large, and the split cannon cables are large in diameter, large in size, large in weight, easy to disperse and wind. Therefore, there is a need to provide a new integral cannon cable, which integrates the cable and the air pipe into the same firm cable, and effectively solves the above problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the integral cannon cable integrates the cable and the air pipe into the same firm cable, and has the advantages of small diameter, light weight, firmness and durability.

The utility model provides a pair of whole big gun cable, include, oversheath layer, armor, inner sheath layer, signal cable, supply cable and the high-pressurepipe of arranging from the extroversion inwards.

Further, the high-pressure air pipe (and the inner sheath layer) is tightly filled with the signal cable and/or the power supply cable, and is provided with an exhaust filling rope.

Further, the armor layers are spirally arranged around the outer wall of the inner sheath layer in the axial direction, and the signal cables and the power supply cables are spirally arranged around the outer wall of the high-pressure air pipe in the axial direction.

Further, the high-pressure air pipe is a high-pressure hose.

Further, the vent filling rope has a gap, so that gas seeped from the high-pressure gas pipe is discharged from the end part of the integral gunwire.

Further, the armor layer is composed of high-strength metal wires, high-strength metal bands or high-strength fibers.

Further, the outer sheath layer is made of nylon, polyurethane, polyethylene, rubber or other wear-resistant and corrosion-resistant materials.

Further, the inner sheath layer is made of polyurethane, rubber, polyethylene or other protective materials.

To sum up, the utility model provides a whole big gun cable, its compact structure, arrange neatly, the volume is less, weight reduction, the leakproofness is good, work under long-term focus vibrations condition, it is airtight, no leakage, with gas circuit and circuit design in an organic whole, make its small in size, save space, whole flexible, the intensity of the whole big gun cable of armor reinforcing, make whole big gun cable can bear great vertical pulling force, and protect whole big gun cable inner assembly and avoid damaging, reduce maintenance work, reduce the maintenance cost, use the reliability promotion, in, the oversheath has excellent waterproof nature, oil resistance, corrosion resistance and insulating properties, can prevent the erosion of sea water to whole big gun cable, also have certain pliability when having better mechanical strength, make whole big gun cable crooked more easily.

Detailed Description

The invention will be described in further detail with reference to the following drawings and specific embodiments:

as shown in fig. 1, the utility model provides a pair of whole big gun cable, include, arrange from the extroversion in including the oversheath layer 1, armor 2, inner sheath layer 3, signal cable 4, supply cable 5 and the high-pressurepipe 6 of arranging from the extroversion in, high-pressurepipe 6 with exhaust packing rope 7 has between the inner sheath layer 3.

In a preferred embodiment, the signal cable 4 and/or the power supply cable 5 are tightly filled between the inner sheath layer 3 and the high-pressure air pipe 6; this kind is with signal cable, power supply cable and high-pressurepipe in order to fold layer upon layer, the mode of closely laminating, has saved thickness and the weight of many cable sheaths, and compact structure has greatly reduced the volume and the weight of whole big gun cable.

In a preferred embodiment, the armor layer 2 is arranged around the outer wall of the inner sheath layer 3 in an axial spiral mode, and the signal cable 4 and the power supply cable 5 are arranged around the outer wall of the high-pressure air pipe 6 in an axial spiral mode. The spiral arrangement mode has a compact structure, is orderly arranged, works under the long-term seismic source vibration condition, can effectively disperse longitudinal tension, and is not easy to break, so that the tensile strength of the whole gun cable is improved; the air circuit and the circuit are designed into a whole, so that the ship is small in size, saves space and reduces the weight of the ship body.

In a preferred embodiment, the high-pressure air pipe 6 is a high-pressure hose, is positioned at the center of the whole cannon cable, has good flexibility and can be bent together with the cannon cable.

In a preferred embodiment, the vent filling rope 7 has a gap, so that the gas seeped out from the high-pressure gas pipe 6 is discharged from the end part of the integral gunwire, and the internal components of the integral gunwire are protected from being damaged.

In a preferred embodiment, the armor layer 2 is made of high-strength steel wires, high-strength steel belts or high-strength fibers, the strength of the whole cannon cable is enhanced, and the cannon cable can bear large longitudinal tension, so that the force acting on the whole cannon cable can be dispersed, the local acting force acting on the whole cannon cable is reduced, meanwhile, the internal components of the whole cannon cable are protected from being damaged, the maintenance cost is reduced, the use reliability is improved, and in addition, the high-strength fibers can be adopted for replacement according to actual needs.
