Description

Technical Field

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

[0002] With the accelerating pace of human ocean development, underwater robot technology, as the most important means for humans to explore the ocean, has received unprecedented attention and development. As the key to connecting various underwater devices, cables need to be frequently connected and used. Although existing underwater cables can basically meet the daily use requirements, there are still some deficiencies that need to be improved.

[0003] During the use of underwater robots, the cables widely used in the market are often pulled and towed underwater by the robots. Due to the complex underwater environment, the cables are prone to friction with the stones on the bottom of the water, resulting in surface wear. Therefore, we propose an underwater cable to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an underwater cable to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an underwater cable, including a cable body. Inside the cable body, there are multiple groups of conductor cores. Outside the conductor cores, there is a shielding layer. Between the shielding layer and the conductor cores, there are multiple groups of filling strips. At one end of the shielding layer away from the conductor cores, there is a water-blocking layer. At one end of the water-blocking layer away from the shielding layer, there is a wear-resistant layer.

[0006] As a further preference of this technical solution, the filling strips can be closely attached to the outer wall of the conductor cores and the inner wall of the shielding layer.

[0007] As a further preference of this technical solution, the conductor cores are composed of multiple strands of 6-category copper wires stranded with water-blocking yarns.

[0008] As a further preference of this technical solution, the shielding layer uses fine copper wires as raw materials, and the shielding layer is fixed inside the cable body by a weaving method.

[0009] As a further preference of this technical solution, the wear-resistant layer uses polyurethane as raw material and is sprayed on the surface of the cable body.

[0010] The utility model provides an underwater cable, which has the following beneficial effects:

[0011] The utility model is provided with a shielding layer inside the cable body, enabling the copper braided net to adhere to the surface of the conductor core and effectively shielding the electrical signals emitted by the conductor core, ensuring that the conductor core can transmit signals stably. Then, by arranging a water-blocking layer outside the shielding layer, it can effectively prevent water molecules from entering the inside of the cable body, improving the waterproof performance of the cable body and ensuring that the cable body can be used normally underwater. Furthermore, by spraying a wear-resistant layer on the outermost layer of the cable body, it can effectively improve the wear-resistant performance of the cable body surface, enabling the cable body to be smoothly towed and erected underwater, preventing damage to the cable body surface, and prolonging the overall service life of the cable body.

[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0017] The utility model provides the following technical solutions: As Figures 1 to 3 shown, in this embodiment, an underwater cable includes a cable body 1. A plurality of conductor cores 2 are arranged inside the cable body 1. A shielding layer 3 is arranged outside the conductor cores 2. A plurality of filler strips 4 are filled between the shielding layer 3 and the conductor cores 2. A water-blocking layer 5 is arranged at one end of the shielding layer 3 away from the conductor cores 2. A wear-resistant layer 6 is arranged at one end of the water-blocking layer 5 away from the shielding layer 3.

[0018] By arranging a shielding layer 3 inside the cable body 1, the copper braided mesh can be attached to the surface of the conductor core 2, and the electrical signals emitted by the conductor core 2 can be effectively shielded. Then, through multiple sets of filling strips 4 installed inside the cable body 1, the gap between the cable body 1 and the conductor core 2 can be effectively reduced, thereby preventing air from entering the cable body 1, ensuring that the entire cable body 1 can be attached to the bottom of the water. Further, through the water-blocking layer 5 arranged outside the shielding layer 3, water molecules can be effectively prevented from entering the cable body 1, improving the waterproof performance of the cable body 1 and ensuring that the cable body 1 can be used normally at the bottom of the water. Additionally, through the wear-resistant layer 6 sprayed on the outermost layer of the cable body 1, the wear-resistant performance of the surface of the cable body 1 can be effectively improved, enabling the cable body 1 to be smoothly towed and erected at the bottom of the water, preventing damage to the surface of the cable body 1, and extending the overall service life of the cable body 1.

[0019] In other embodiments, the filling strip 4 can be closely attached to the outer wall of the conductor core 2 and the inner wall of the shielding layer 3.

[0020] Through this design, the gap between the cable body 1 and the conductor core 2 can be effectively reduced, thereby preventing air from entering the cable body 1 and preventing the entire cable body 1 from floating.

[0021] In other embodiments, the conductor core 2 is formed by stranding multiple 6 - type copper wires and water-blocking yarns.

[0022] Through this design, the overall flexibility and water-blocking performance of the conductor core 2 can be effectively improved, thus facilitating the towing of the cable body 1 by the underwater robot.

[0023] In other embodiments, the shielding layer 3 is made of fine copper wires and is fixed inside the cable body 1 in a braided manner.

[0024] By braiding the fine copper wires into a copper braided mesh and placing the copper braided mesh outside the conductor core 2, the copper braided mesh can be attached to the surface of the conductor core 2, and the entire copper braided mesh has good flexibility and shielding performance, which can effectively shield the electrical signals emitted by the conductor core 2 and also facilitate the towing operation of the cable body 1.

[0025] In other embodiments, the water-blocking layer 5 is made of polyurethane as the raw material.

[0026] Since the polyurethane waterproof material is mainly two-component, composed of polyurethane and curing agent, a chemical reaction will occur after mixing to generate polyurethane elastomer, and this elastomer has excellent waterproof performance, thereby effectively preventing water molecules from entering the cable body 1.

[0027] In other embodiments, the wear-resistant layer 6 is made of polyurethane as the raw material.

[0028] The wear-resistant layer 6 is sprayed on the surface of the cable body 1 with polyurethane as the raw material, which can form a protective film on the surface of the cable body 1. When the cable body 1 is dragged along the bottom of the water, it can effectively reduce the wear on the surface of the cable body 1, effectively improve the overall wear resistance of the cable body 1, and effectively prevent the surface of the cable body 1 from being damaged.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
