It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

At present, an umbilical cable is widely applied to the field of ocean engineering and provides power for underwater facilities and equipment or transmits media such as electricity, gas, liquid and the like. The armored umbilical cable reinforced by steel wire armor in the related technology can overcome the tension of the self weight of the umbilical cable, and the umbilical cable is heavy and high in cost and is mostly applied to deep sea facilities. And the use of armored umbilical cables in underwater facilities and equipment operated in shallow sea is not economical. Based on this, this application embodiment provides a low cost's plain type umbilical cable for shallow water operation, uses the inside pipeline of insulating sheath cladding umbilical cable, compares with conventional armoured umbilical cable, has abandoned the scheme that carries out steel wire armouring and strengthens to the oversheath of umbilical cable, and insulating sheath protects the demand of metal rope and a plurality of conveyer pipes when can satisfy umbilical cable shallow water operation equally to insulating sheath's preparation is simpler, and the cost is lower.

The technical solution provided by the present invention is described in detail below with reference to the accompanying drawings 1-3.

Fig. 1 is a schematic structural diagram of a cross section of an umbilical provided in an embodiment of the present application.

As shown in fig. 1, an umbilical provided by an embodiment of the present application may include: a metal cord 2, a plurality of delivery tubes 3, and an insulating sheath 1 covering the metal cord 2 and the plurality of delivery tubes 3.

In the present embodiment, the metal rope 2 may be used to carry the weight of the umbilical itself and the weight of the underwater working equipment. The plurality of delivery pipes 3 can be used for delivering media such as water, gas, oil, etc. or delivering signals such as electric power, sensor signals, etc. The insulating sheath 1 has insulating property, wear-resisting anticorrosive property, can protect metal rope and a plurality of conveyer pipes when the umbilical cable shallow water operation.

It should be noted that compared with the conventional steel wire armoured structure, the insulating sheath can also meet the requirement of protecting the metal rope and a plurality of conveying pipes during the shallow water operation of the umbilical cable, and the manufacturing of the insulating sheath is simpler and the cost is lower.

Further, in the present embodiment, the insulating sheath 1 may be a heat shrinkable tube. The heat shrinkable tube is a special polyolefin heat shrinkable sleeve. The heat shrinkable tube can be formed by compounding and processing a high-quality soft cross-linked polyolefin material adopted by the outer layer and a hot melt adhesive material adopted by the inner layer, the outer layer has the characteristics of insulation, corrosion resistance, wear resistance and the like, the inner layer has the advantages of low melting point, water tightness, high adhesion and the like, and the heat shrinkable tube has the sealing and water-proof functions of a plurality of strands of wire harnesses.

It can be understood that, the material of the heat shrinkable tube is not particularly limited in the embodiments of the present application, and the specific type of the heat shrinkable tube can be flexibly selected according to the operation requirement of the underwater equipment. For example, the heat shrinkable tube may be a double-wall heat shrinkable tube containing glue, or other heat shrinkable tubes with high-temperature shrinkage, softness, flame retardancy, and insulation corrosion prevention functions.

It should be pointed out that, the pyrocondensation pipe of umbilical cable cuts off the back, and metal rope and all kinds of conveyer pipes in the umbilical cable of convenient change, maintenance, metal rope and all kinds of conveyer pipes are better after changing, carry out the pyrocondensation again to the pyrocondensation pipe and can continue to use this umbilical cable, further reduce the cost of umbilical cable.

It can be understood that, the customization degree of conventional armoured umbilical cable is high, and working range is single, because armor structure, umbilical cable internal line is highly concentrated fixedly, if certain pipeline appears damaging, can't effectively change, and whole umbilical cable all will be unable to use. Compare with conventional armor umbilical, the change of inside pipeline can be realized to the umbilical that this application embodiment provided, has increased the whole life of umbilical, has enlarged the application range of umbilical.

That is, the conveying pipes flexibly arranged according to the underwater work requirement may include one or more types, and the number of each type of conveying pipe flexibly selected according to the underwater work requirement may be one or more. For example, in one particular embodiment, as shown in FIG. 1, a signal cable 31, two air tubes 32, an ultra high pressure tube 33, and six hydraulic hoses 34 may be provided within the umbilical.

It should be noted that, compared with the umbilical cable of the conventional steel wire armoured structure, the plurality of conveying pipes provided by the embodiment of the present application are not provided with the filling layer therebetween, and at least two conveying pipes in the plurality of conveying pipes are in contact with each other. Specifically, viewed from the cross section of the umbilical cable, the cross sections of the two conveying pipes can be tangent under an ideal condition, and a small part of the two conveying pipes are in contact; when the umbilical cable actually carries out shallow water work, because do not set up the filling layer between a plurality of conveyer pipes, pressure probably makes two conveyer pipes extrusion deformation each other under water, and the space between the conveyer pipe diminishes, and two conveyer pipes large tracts of land contact. Compared with the conventional armored umbilical cable, the umbilical cable provided by the embodiment of the application has no filling layer, is simpler to manufacture and has lower cost.
