TECHNICAL FIELD

[0001] The present application relates to the technical field of cables, in particular to a floating cable. BACKGROUND

[0002] In the fields of power transmission and communication, cables play a crucial role as transmission media. However, in certain application scenarios such as underwater, marshland, or environments requiring crossing rivers, traditional cables are prone to sinking, displacement, or damage due to their own weight and water flow, thereby affecting normal power transmission or communication. To address this issue, people have begun to explore and develop cables with floating capabilities to adapt to the needs of the above-mentioned special environments.

[0003] Currently, floating cables on the market usually increase buoyant materials on the outside of the cable to achieve the floating effect. However, the existing floating cables often have insufficient buoyancy and poor tensile strength, limiting their long-term use in harsh environments such as underwater.

[0004] Therefore, how to design a cable that not only has good floating performance but also has excellent tensile strength has become a problem to be solved in the current cable technology field. CONTENT OF THE INVENTION

[0008] By adopting the above technical solutions, the conductor core is made of copper foil wire, which makes the cable have excellent electrical conductivity. The insulating layer wrapped on the outer side of the conductor core serves the purpose of electrical insulation protection. The tensile layer made of Kevlar material enables the cable to have strong tensile strength. The buoyancy layer made of modified TPU foaming material enables the cable to float in water while maintaining the stability of buoyancy. Therefore, the present application has good floating performance and excellent tensile strength.

[0015] Optionally, the modified TPU foaming material of the buoyancy layer has a closed cell structure for providing buoyancy to the cable.

[0016] By adopting the technical scheme, the buoyancy layer can provide stable and lasting buoyancy to the cable.

[0017] Optionally, the thickness of the buoyancy layer is greater than the thickness of the insulating layer.

[0018] By adopting the technical scheme, the thickness of the buoyancy layer is designed to be greater than the thickness of the insulating layer, which can ensure that the cable has sufficient buoyancy.

[0025] Optionally, a conductive shielding layer is arranged between the outer skin layer and the buoyancy layer.

[0026] By adopting the technical scheme, the conductive shielding layer is arranged between the outer skin layer and the buoyancy layer, so that the electromagnetic interference signals from the outside can be effectively absorbed and reflected, thereby ensuring the stability and accuracy of the signal transmission inside the cable.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0036] In the description of the embodiments of the present application, the words such as "for example" or "for instance" are used to represent an example, illustration or description. Any embodiment or design scheme described as "for example" or "for instance" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as "for example" or "for instance" are intended to present the relevant concept in a specific manner.

[0037] In the description of the embodiments of the present application, the term "a plurality of" means two or more. For example, a plurality of systems means two or more systems, and a plurality of screen terminals means two or more screen terminals.

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] Referring to Figure 1 In the embodiments of the present application, a floating cable is disclosed, comprising: a conductor core 10, an insulation layer 20, a tensile layer 30, a buoyancy layer 40 and an outer skin layer 50 which are sequentially wrapped.

[0040] The conductor core 10 is made of copper foil wire to form the core of the cable, which can make the core have good electrical conductivity. The insulation layer 20 is made of Teflon material, which is seamlessly and uniformly wrapped on the outer side of the conductor core 10 for insulation protection. In this way, the integrity and consistency of the insulation layer 20 can be ensured, and electrical failure caused by unevenness or gaps in the insulation layer 20 can be prevented, thereby improving the safety and reliability of the cable.

[0041] The tensile layer 30 is made of Kevlar material, i.e. bulletproof silk, which is woven to wrap the outer side of the insulation layer 20 away from the conductor core 10, so as to enhance the tensile resistance of the cable.

[0042] The buoyancy layer 40 is made of modified TPU (thermoplastic polyurethane elastomer rubber) foaming material, which is wrapped on the outer side of the tensile layer 30 away from the insulation layer 20, so as to make the cable float in water while maintaining the stability of the buoyancy.

[0043] The outer skin layer 50 is made of wear-resistant TPU material, which is wrapped on the outer side of the buoyancy layer 40 away from the tensile layer 30, so as to protect the internal structure from the external environment, thereby playing a role of external protection and prolonging the service life of the cable.

[0044] Specifically, the conductor core 10 is twisted by multiple small copper foil wires, which can increase the surface area and electrical conduction path of the conductor core 10, thereby improving its electrical conductivity efficiency and flexibility. In addition, such design makes the cable more flexible when bending or twisting, reducing the risk of failure caused by the fracture of the conductor core 10.

[0045] In another embodiment, the tensile layer 30 can also adopt a composite weaving structure, combining Kevlar with other high-strength fibers such as carbon fiber or glass fiber to form a hybrid woven tensile layer 30, so that the cable has strong tensile resistance, wear resistance and durability.

[0046] The modified TPU foaming material of the buoyancy layer 40 has a closed-cell structure, which can provide stable and lasting buoyancy for the cable. In addition, the thickness of the buoyancy layer 40 is greater than the thickness of the insulation layer 20, which can further ensure that the cable has sufficient buoyancy.

[0047] In another embodiment, the buoyancy layer 40 also adopts another high-performance foaming material, such as polyethylene foaming material, which also has excellent buoyancy characteristics and strong weather resistance, and can maintain stable performance in various harsh environments.

[0048] The outer surface of the outer skin layer 50 is provided with anti-skid texture, which can increase the friction of the cable surface, and facilitate fixing and anti-skid during installation and operation.

[0049] Further, in order to increase the adhesion between the insulation layer 20 and the conductor core 10, in this embodiment, an adhesive layer 60 is arranged between the insulation layer 20 and the conductor core 10.

[0050] The adhesive layer 60 can adopt epoxy resin material, so that the adhesive layer 60 has good adhesion and weather resistance, and can increase the overall structure.

[0051] Further, in order to ensure the stability and accuracy of the internal signal transmission of the cable, in this embodiment, a conductive shielding layer 70 is added between the buoyancy layer 40 and the outer skin layer 50, which can effectively absorb and reflect external electromagnetic interference signals. The material of the conductive shielding layer 70 is not limited in this embodiment.

[0052] In summary, the floating cable disclosed in the embodiment of the present application adopts modified TPU foaming material as the buoyancy layer 40, which can make the cable have good buoyancy, can float on the water surface, and is convenient for cable laying in water operation or wet environment; the insulation layer 20 adopts Teflon material, which is used for electrical insulation protection; the tensile layer 30 adopts Kevlar material, which can make the cable have strong tensile property; the outer skin layer 50 adopts TPU material, which can play a role in external protection. Therefore, the cable can have good floating performance and excellent tensile property.

[0053] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
