Description

TECHNICAL FIELD

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

[0002] The outer sheath of the floating cable is usually made of special foaming material. This material has a low density, so that the overall density of the cable can be equal to or less than the density of water. Therefore, when the cable is placed in water, it can be supported by sufficient buoyancy and float on the water surface. Because the cable has a low density, the wear and tear on the outside of the cable will increase when it is bent in water, resulting in a reduced service life of the cable. CONTENT OF THE UTILITY MODEL

[0003] In view of the deficiencies in the prior art, the purpose of the present application is to provide a floating cable special for underwater robots to solve the technical problems in the background art.

[0004] The above-mentioned purpose of the present application is achieved by the following technical solution: a floating cable special for underwater robots, comprising an outer cable and a plurality of cable cores inside, wherein the outer cable is provided with an outer wrapping layer inside, the outer wrapping layer surrounds the plurality of cable cores, a plurality of cylindrical holes are formed in the outer wrapping layer, a plurality of strip-shaped columns are placed in the cylindrical holes, and the strip-shaped columns are filled with a gas having a density less than water.

[0005] By adopting the above-mentioned technical solution, the cable material in the present application uses normal material, and the buoyancy is improved by the gas in the strip-shaped columns inside the wrapping layer, so that the cable can float while ensuring the service life of the cable.

[0006] Further, an outer connecting assembly is arranged between the outer cable and the outer wrapping layer, and an inner wrapping layer is further arranged between the outer wrapping layer and the cable core.

[0007] By adopting the above-mentioned technical solution, considering that the pressure under water will extrude the cable core inside the cable, the present application provides a plurality of protective layers for the cable core.

[0008] Further, the outer connecting assembly comprises an outer connecting strip fixedly connected to the inner side of the outer cable, the other end of the outer connecting strip is fixedly connected to the outer wrapping layer, and an inner connecting assembly is arranged between the outer wrapping layer and the inner wrapping layer.

[0009] By adopting the above-mentioned technical solution, the outer connecting strip arranged between the outer wrapping layer and the outer cable can improve the connectivity between the outer cable and the outer wrapping layer.

[0010] Further, the inner connecting assembly comprises an inner connecting strip fixedly connected to the inner side of the outer wrapping layer, and the other end of the inner connecting strip is fixedly connected to the inner wrapping layer.

[0011] Through the adoption of the above technical solutions, the inner connecting strip can improve the connectivity between the outer wrapping layer and the inner wrapping layer.

[0012] Further, there is a certain gap between the outer cable and the outer wrapping layer, and the same gap exists between the outer wrapping layer and the inner wrapping layer.

[0013] Through the adoption of the above technical solutions, by allowing a gap between the multiple layers, compression space can be provided and weight can be reduced, ensuring that the buoyancy of the cable is sufficient.

[0014] Further, the outer side of the outer cable is fixedly provided with a corrosion-resistant layer.

[0015] Through the adoption of the above technical solutions, the corrosion-resistant layer further improves the service life of the cable underwater.

[0016] Further, the inner wrapping layer is internally provided with a flexible filling layer for wrapping the cable core.

[0017] Further, the flexible filling layer is made of flexible rubber.

[0018] Through the adoption of the above technical solutions, the flexible filling layer not only protects the cable core but also has a certain flexibility and elasticity, ensuring that there is a space for compression and elasticity underwater.

[0019] In summary, the present application includes the following beneficial technical effects: by providing a cylindrical hole in the outer wrapping layer and placing a strip-shaped column filled with a gas having a density less than water, the buoyancy of the cable is significantly enhanced. This design allows the cable to maintain a good floating state even underwater, thereby reducing the energy consumption of the underwater robot when dragging the cable and improving the working efficiency of the robot. Although the cable material is made of normal materials, the multi-layer structure (including the outer cable, the outer wrapping layer, the inner wrapping layer, etc.) provides all-round protection for the cable. These protective layers not only effectively resist corrosion and wear in underwater environments, but also act as a buffer when the cable is subjected to external pressure, thereby prolonging the service life of the cable. The setting of the outer connecting assembly and the inner connecting assembly enhances the connectivity between the layers of the cable, making the overall structure of the cable more stable. This stability not only helps to maintain the floating state of the cable underwater, but also prevents the cable from twisting or breaking in complex underwater environments. The gaps between the outer cable and the outer wrapping layer, and the outer wrapping layer and the inner wrapping layer provide the necessary compression space for the cable, allowing it to maintain a certain elasticity and adaptability in different water depths and water pressure environments. This adaptability helps to ensure the stable operation of the cable in underwater environments. BRIEF DESCRIPTION OF DRAWINGS

[0022] The application will be further described in detail below with reference to the accompanying drawings.

[0023] Embodiment, refer to Figure 1 The floating cable special for underwater robots includes an outer cable 1 and a plurality of cable cores 10 inside. The outer cable 1 is provided with an outer wrapping layer 3, which surrounds the plurality of cable cores 10. A plurality of cylindrical holes are formed in the inner part of the outer wrapping layer 3, and a plurality of strip-shaped columns 4 are placed in the cylindrical holes. The strip-shaped columns 4 are filled with gas having a density less than water. The cable material in the application adopts normal material, and the buoyancy is improved by the gas in the strip-shaped columns in the wrapping layer, so that the cable can float and the service life of the cable can be guaranteed.

[0024] In the embodiment, an outer connecting assembly is arranged between the outer cable 1 and the outer wrapping layer 3, and an inner wrapping layer 2 is further arranged between the outer wrapping layer 3 and the cable core 10. Considering that the underwater pressure will extrude the cable core 10 inside the cable, the cable core 10 is provided with multi-layer protection in the application.

[0025] In the embodiment, the outer connecting assembly includes an outer connecting strip 31 fixedly connected to the inner side of the outer cable 1, and the other end of the outer connecting strip 31 is fixedly connected to the outer wrapping layer 3. An inner connecting assembly is arranged between the outer wrapping layer 3 and the inner wrapping layer 2. The outer connecting strip 31 arranged between the outer wrapping layer 3 and the outer cable 1 can improve the connectivity between the outer cable 1 and the outer wrapping layer 3.

[0026] In the embodiment, the inner connecting assembly includes an inner connecting strip 21 fixedly connected to the inner side of the outer wrapping layer 3, and the other end of the inner connecting strip 21 is fixedly connected to the inner wrapping layer 2. The arrangement of the inner connecting strip 21 can improve the connectivity between the outer wrapping layer 3 and the inner wrapping layer 2.

[0027] In the embodiment, there is a certain gap between the outer cable 1 and the outer wrapping layer 3, and there is also the same gap between the outer wrapping layer 3 and the inner wrapping layer 2. By allowing the gaps between the multiple layers, the compression space can be provided and the weight can be reduced, so that the buoyancy of the cable is sufficient.

[0028] In the embodiment, a corrosion-resistant layer is fixedly arranged on the outer side of the outer cable 1. The arrangement of the corrosion-resistant layer further improves the service life of the cable under water.

[0029] In this embodiment, the inner wrapping layer 2 and the inner part are provided with a flexible filling layer 11 for wrapping the cable core 10, which is made of flexible rubber. The flexible filling layer 11 not only protects the cable core 10 but also has certain flexibility and elasticity, ensuring the underwater compression has elasticity space.

[0030] Specific use process: First, the outer cable 1 is internally provided with an outer wrapping layer 3, which surrounds the multiple groups of cable cores 10 and plays a preliminary protection role. The outer wrapping layer 3 is ingeniously provided with multiple cylindrical holes inside, in which the strip-shaped columns 4 filled with gas with a density less than water are placed. This design ingeniously utilizes the buoyancy of the gas, enabling the cable to maintain a floating state underwater, while avoiding the additional burden on the underwater robot caused by the heavy cable. It is worth noting that although this special design is adopted, the material of the cable is still normal, thereby ensuring its basic electrical performance and mechanical strength.

[0031] In order to further enhance the durability and stability of the cable, the outer connecting assembly is arranged between the outer cable 1 and the outer wrapping layer 3, and the inner wrapping layer 2 is arranged between the outer wrapping layer 3 and the cable core 10 in this embodiment. The outer connecting assembly includes outer connecting strips 31 fixedly connected to the inner side of the outer cable 1, and the other ends of the connecting strips are fixedly connected to the outer wrapping layer 3, thereby enhancing the connectivity between the two. Similarly, the inner connecting assembly includes inner connecting strips 21 fixedly connected to the inner side of the outer wrapping layer 3, and the other ends of the connecting strips are fixedly connected to the inner wrapping layer 2, further improving the stability and overall structural strength of the cable.

[0032] In addition, in order to cope with the pressure changes that may be brought about by the underwater environment, certain gaps are reserved between the outer cable 1 and the outer wrapping layer 3, and between the outer wrapping layer 3 and the inner wrapping layer 2 in this embodiment. These gaps not only provide the necessary compression space, enabling the cable to maintain a certain elasticity and adaptability in the underwater environment, but also help to reduce the overall weight of the cable, further improving its buoyancy.

[0033] Considering the corrosive nature of the underwater environment, a corrosion-resistant layer is fixedly arranged on the outer side of the outer cable 1 in this embodiment. This layer can effectively resist the corrosion of corrosive substances underwater, thereby prolonging the service life of the cable.

[0034] Finally, the inner wrapping layer 2 is internally provided with a flexible filling layer 11 for wrapping the cable core 10. This layer is made of flexible rubber, not only having good protection performance, but also being able to provide certain flexibility and elasticity, so that the cable can have certain elasticity space when compressed underwater, thereby maintaining the integrity of its structure and the stability of its function.

[0035] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
