Description

Technical Field

[0001] The utility model relates to the technical field of underwater cables, in particular to a special underwater coaxial cable. Background Art

[0002] In underwater environments, the use of cables faces many challenges. Traditional underwater cable designs often have difficulty effectively coping with complex and changeable water flow environments, making the cables vulnerable to water flow impact and damage. This not only affects the service life of the cables, but may also have a serious impact on the normal operation of underwater equipment.

[0003] Specifically, traditional underwater cables may have deficiencies in design and material selection, which makes the cables lack sufficient stability and durability when facing the impact of water flow. For example, the outer sheath of some cables may not be able to effectively resist the erosion of water flow, resulting in damage to the outer sheath, which in turn affects the wires inside the cable. In addition, the complexity and uncertainty of the underwater environment may also interfere with the signal transmission of the cable and affect the normal operation of underwater equipment. In view of this, we propose a coaxial cable specifically for underwater use. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A special underwater coaxial cable comprises a cable body 1, with a guide plate 2 installed on both sides of the cable body 1. The cross-section of the guide plate 2 is triangular, and the end away from the cable body 1 is a vertex of the triangle. A guide groove 22 is provided on the surface of the guide plate 2. The inside of the guide plate 2 is hollow, and the top and bottom inner walls are integrally formed with a reinforcing net 21. A T-shaped plug plate 23 is integrally formed on the outer wall of the guide plate 2 close to the cable body 1. A slot 10 connected to the T-shaped plug plate 23 is opened on the outer wall of the cable body 1, and the T-shaped plug plate 23 fits tightly with the slot 10. By installing guide plates 2 on both sides of the cable body 1, the cross-section of the guide plates 2 is designed to be triangular, which can optimize the flow state of water when passing through the cable, reduce the impact of water on the cable, and improve the stability of the cable underwater. The interior of the guide plate 2 is designed to be hollow, which can reduce the weight of the entire cable and facilitate installation and movement. The design of the reinforcing net 21 enhances the structural strength of the guide plate 2 and improves its durability. The design of the T-shaped plug plate 23 and the slot 10 enables the guide plate 2 to be firmly connected to the cable body 1, ensuring the stability and reliability of the structure and facilitating disassembly.

[0024] As a preferred embodiment of the present invention, the cable body 1 includes an inner conductor layer 11 located at the innermost part and an outer conductor layer 14 in the middle, and an insulating layer 13 is provided between the inner conductor layer 11 and the outer conductor layer 14. These three layers constitute the basic structure of the coaxial cable, which can realize effective signal transmission.

[0025] As a preferred embodiment of this embodiment, a waterproof film 12 is provided between the insulating layer 13 and the inner conductor layer 11, thereby improving the waterproof performance of the cable and ensuring stable signal transmission when used underwater.

[0026] As a preferred embodiment of the present invention, a water-blocking layer 15 is provided on the outer side of the outer conductor layer 14, a sheath 17 is provided on the outer side of the water-blocking layer 15, and the slot 10 is opened on the sheath 17. The water-blocking layer 15 further enhances the waterproof capability of the cable and protects the internal structure from being corroded by water. The design of the sheath 17 provides additional physical protection for the cable and enhances the durability and service life of the cable.

[0027] As a preferred embodiment of this embodiment, a shielding layer 16 is provided between the water-blocking layer 15 and the sheath 17, which can effectively reduce the influence of external electromagnetic interference on signal transmission and improve signal quality.

[0028] As a preferred embodiment of the present invention, the guide plate 2 and the sheath 17 are made of the same material, and the inner wall of the slot 10 and the surface of the T-shaped plug plate 23 are provided with anti-skid patterns. The guide plate 2 and the sheath 17 are made of the same material, which simplifies the production process and ensures the compatibility of the two. The anti-skid patterns designed on the inner wall of the slot 10 and the surface of the T-shaped plug plate 23 enhance the stability of the connection and prevent loosening that may occur during underwater use.

[0029] As a preferred embodiment of the present invention, the insulating layer 13 is made of ceramic, and the shielding layer 16 is woven from steel wire or tinned copper mesh. The insulating layer 13 is made of ceramic material, which improves the high temperature resistance and insulation performance of the cable and ensures the stability and safety of signal transmission. The shielding layer 16 is woven from steel wire or tinned copper mesh, which effectively improves the anti-interference ability of the cable and ensures high-quality signal transmission.

[0030] The underwater special coaxial cable of the utility model ensures efficient and stable transmission of signals in an underwater environment based on its unique structural design and material selection.

[0031] First, the core part of the cable is composed of an inner conductor layer 11, a waterproof film 12, an insulating layer 13 and an outer conductor layer 14, forming a coaxial structure. When the signal is transmitted in the inner conductor layer 11, the insulating layer 13 and the outer conductor layer 14 work together to form an electromagnetic shield to protect the signal from external electromagnetic interference. This coaxial design ensures the accuracy and stability of signal transmission.

[0032] The waterproof film 12 is located between the inner conductor layer 11 and the insulating layer 13 to prevent water from penetrating. In an underwater environment, the waterproof film 12 effectively blocks the contact between water and the internal structure of the cable, thereby protecting the signal transmission from being affected by water.

[0033] The water-blocking layer 15 is located outside the outer conductor layer 14, further enhancing the waterproof performance of the cable. Even in extreme cases, if moisture breaks through the waterproof film 12, the water-blocking layer 15 can also play a secondary protective role to prevent moisture from further corroding the internal structure of the cable.

[0034] The shielding layer 16 is located between the water-blocking layer 15 and the sheath 17 and is woven from steel wire or tinned copper mesh. This layer can effectively absorb and reflect external electromagnetic interference, ensuring that the signal is not affected by external electromagnetic noise during transmission, thereby improving signal clarity and transmission efficiency.

[0035] As the outermost layer of the cable, the sheath 17 provides physical protection for the internal structure. It can not only resist physical impact in the underwater environment, but also prevent the cable from being scratched or damaged by sharp objects.

[0036] In addition, the guide plates 2 on both sides of the cable body 1 play a key role in guiding the water flow. Its triangular cross-section design can optimize the flow state of water when it passes through the cable and reduce the impact of the water flow on the cable. This not only improves the stability of the cable underwater, but also extends the service life of the cable.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model.
