[0003] In nearshore areas, cables are sometimes punctured by fishhooks during use, causing damage to the outer layer of the cable and reducing its service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a near-shore cable that prevents fishhook entanglement and barbs, thereby solving the technical problems in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a near-shore anti-fishhook entanglement and barb protection cable, comprising multiple sets of cable cores and an outer cable shell, wherein an inner protective layer for wrapping the cable cores is provided on the outside of the cable cores, an outer protective layer is provided between the inner protective layer and the cable shell, the outer protective layer wraps the inner protective layer, and a connecting component for connecting the inner and outer protective layers is provided inside the cable shell.

[0006] By adopting the above technical solution, through a multi-layered setup, specifically an outer protective layer, an inner protective layer, and a cable outer shell, and connecting them together with a connecting component to wrap the cable core, even if the fishhook pierces the cable outer shell, it will not affect the internal cable core.

[0007] Furthermore, the connecting assembly includes an outer support strip inside the cable housing, and an outer protective layer is fixedly connected to the other side of the outer support strip.

[0008] By adopting the above technical solution, the outer support strip connects the outer cable shell and the outer protective layer together, improving their connectivity.

[0009] Furthermore, the connecting component also includes an inner support strip fixedly connected inside the outer protective layer, with the other end of the inner support strip fixedly connected to the inner protective layer.

[0010] By adopting the above technical solution, the inner support strip is used to maintain a certain distance between the outer protective layer and the inner protective layer.

[0011] Furthermore, an anti-corrosion layer is fixedly provided on the outer side of the outer protective layer.

[0012] By adopting the above technical solution, when a fishhook pierces the cable outer shell, the anti-corrosion layer can also reduce the corrosion of the inside by seawater.

[0013] Furthermore, a damping sheet is fixedly provided on the outer side of the anti-corrosion layer.

[0014] By employing the above technical solutions, cables may suffer various mechanical damages during laying and use, such as compression and abrasion. The damping sheet, as an additional protective layer, can provide extra mechanical protection for the cable, reducing the impact of these damages.

[0015] Furthermore, there is a certain gap between the anti-corrosion layer and the cable shell, and a flexible filler is used to fill the gap between the inner protective layer and the outer protective layer.

[0016] By adopting the above technical solution, the flexible filler can provide support for the outside of the cable.

[0017] Furthermore, the inner protective layer is provided with a flexible insulating layer for wrapping multiple sets of cable cores.

[0018] By adopting the above technical solution, the flexible insulation layer can further protect the inside of the cable core.

[0019] Furthermore, the flexible insulating layer is made of a polymer material.

[0020] In summary, this application offers the following beneficial technical effects: the multi-layered structure and connecting components significantly enhance the cable's resistance to damage, durability, safety, and transmission performance. Specifically, the cable, through the tight cooperation of its outer shell, outer protective layer, and inner protective layer, constructs a robust protective barrier. Even if the cable shell is pierced by sharp objects such as fishhooks, the outer and inner protective layers continue to provide protection, effectively preventing damage from spreading to the cable core and ensuring the normal operation of the cable's transmission function. Simultaneously, the use of corrosion-resistant materials for the cable shell and outer protective layer, along with the reinforced design of connecting components such as support bars, significantly enhances the cable's corrosion resistance and mechanical strength, enabling it to operate stably for extended periods in harsh marine environments. Furthermore, the multi-layered structure allows for convenient partial replacement of the cable when damaged, reducing maintenance costs and improving repair efficiency. More importantly, the tight wrapping of the inner protective layer effectively isolates external environmental interference, protects the electrical performance of the cable core, and reduces signal attenuation during transmission, thereby improving the cable's transmission efficiency and quality.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Example, refer to Figure 1 A near-shore cable designed to prevent entanglement and barbs from fishhooks comprises multiple inner cable cores 1 and an outer cable shell 2. An inner protective layer 11 is provided on the outside of the inner cable cores 1 to enclose them. An outer protective layer 12 is positioned between the inner protective layer 11 and the cable shell 2, enclosing the inner protective layer 11. A connecting assembly is provided inside the cable shell 2 to connect the inner protective layer 11 and the outer protective layer 12. Through this multi-layered design—specifically, the outer protective layer 12, the inner protective layer 11, and the cable shell 2—and their connection via the connecting assembly, the cable cores 1 are protected. Even if a fishhook pierces the cable shell 2, it will not affect the inner cable cores 1.

[0025] In this embodiment, the connecting assembly includes an outer support strip 3 inside the cable shell 2, and an outer protective layer 12 is fixedly connected to the other side of the outer support strip 3. The outer support strip 3 connects the outer cable shell 2 and the outer protective layer 12 together, improving their connectivity.

[0026] In this embodiment, the connecting assembly further includes an inner support strip 31 fixedly connected inside the outer protective layer 12, with the other end of the inner support strip 31 fixedly connected to the inner protective layer 11. The inner support strip 31 is used to maintain a certain distance between the outer protective layer 12 and the inner protective layer 11.

[0027] In this embodiment, an anti-corrosion layer 21 is fixedly provided on the outer side of the outer protective layer 12. When a fishhook pierces the cable outer shell 2, the anti-corrosion layer 21 can also reduce the corrosion of the interior by seawater.

[0028] In this embodiment, a damping plate is fixedly installed on the outer side of the anti-corrosion layer 21. During the laying and use of cables, they may be subjected to various mechanical damages, such as compression and abrasion. As an additional protective layer, the damping plate can provide extra mechanical protection for the cable and reduce the impact of these damages on the cable.

[0029] In this embodiment, a flexible filler 32 is filled between the inner protective layer 11 and the outer protective layer 12. The flexible filler 32 can provide support for the outer side of the cable.

[0030] In this embodiment, a flexible insulation layer 10 for wrapping multiple sets of cable cores 1 is disposed inside the inner protective layer 11. The flexible insulation layer 10 can further protect the inside of the cable cores 1. The flexible insulation layer 10 is made of polymer material.

[0031] Specific usage process: It consists of multiple sets of cable cores 1, each set of cable cores 1 is tightly wrapped by an inner protective layer 11, providing initial electrical protection and mechanical support. The inner protective layer 11 is made of high-strength, corrosion-resistant material, which can effectively resist the erosion of the external environment.

[0032] Outside the inner protective layer 11 is the outer protective layer 12. The outer protective layer 12 not only encloses the inner protective layer 11 but is also tightly connected to the cable outer shell 2 via connecting components. The connecting components include an outer support strip 3 inside the cable outer shell 2 and an inner support strip 31 inside the outer protective layer 12, which are respectively fixedly connected to the outer protective layer 12 and the inner protective layer 11, forming a robust structural system. This design not only enhances the overall strength of the cable but also ensures a tight fit between the layers, effectively preventing the penetration of moisture and humidity.

[0033] The cable outer shell 2, as the outermost protective barrier, is made of corrosion-resistant and wear-resistant materials, and has excellent waterproof and anti-aging properties. Even if it is pierced by sharp objects such as fishhooks, the cable outer shell 2 can provide effective protection, ensuring that the internal cable core 1 is not affected.

[0034] To further enhance the durability and safety of the cable, an anti-corrosion layer 21 is fixedly installed on the outer side of the outer protective layer 12. The anti-corrosion layer 21 is made of a special anti-corrosion material, effectively resisting the corrosive effects of seawater and extending the cable's service life. Simultaneously, a damping plate is also fixedly installed on the outer side of the anti-corrosion layer 21, providing additional mechanical protection for the cable. As an additional protective layer, the damping plate reduces damage such as compression and abrasion experienced by the cable during laying and use, ensuring the cable's integrity and functionality.

[0035] In addition, a certain gap is left between the outer protective layer 12 and the cable shell 2, and this gap is filled with a flexible filler 32. The flexible filler 32 not only provides additional support for the cable, but also acts as a buffer when the cable is subjected to external forces, reducing cable deformation and damage.

[0036] The inner protective layer 11 contains a flexible insulation layer 10 for wrapping multiple cable cores 1. The flexible insulation layer 10 is made of a high-polymer material, possessing excellent insulation and high-temperature resistance. It effectively isolates electrical interference between the cable cores 1, ensuring the stability and accuracy of the cable's signal transmission. Simultaneously, the flexible insulation layer 10 provides additional mechanical protection, preventing damage to the cable cores 1 during laying and use.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
