Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a submarine towing cable. Background Art
[0002] Submarine towed cables are commonly used in various marine exploration and surveying activities, such as marine seismic exploration, scientific research, and military reconnaissance. During installation, the cable is generally connected to the rear of a tugboat, and the depth of the towboat is adjusted according to the speed of the tugboat and the elasticity and weight of the towboat. The tugboat then slowly drags the cable across the seabed while transmitting data or electrical energy through the cable.
[0003] After searching, an existing patent is found for an anti-drag deep-sea exploration waterproof cable, with publication number CN215069370U. In its embodiment, the flexibility and bendability of the cable are increased by means of a notch on the flexible waterproof layer. When dragging and swaying occurs, the notch provides a certain deformation space for the cable to prevent the cable from being torn due to bending and dragging. Moreover, the two layers of notches are staggered, which improves the flexibility of the cable while preventing it from breaking due to insufficient rigidity.
[0004] However, since the submarine dragged cable is installed at the bottom of the seabed for a long time, and there are a large number of fish living in the ocean, in some cases, the fish may be attracted to the vicinity of the cable. These fish may try to gnaw the cable, causing damage to the cable surface, which may cause problems such as leakage or short circuit. Therefore, submarine dragged cables are urgently needed to solve the above problems. Utility Model Content
[0005] In view of the problem that the above-mentioned existing fish may try to gnaw the cable, causing damage to the cable surface, which may cause leakage or short circuit and other problems, the present utility model is proposed.
[0006] Therefore, the purpose of the utility model is to provide a submarine towing cable, which aims to solve the problem that fish may try to gnaw the cable, causing damage to the cable surface, which may cause leakage or short circuit and other problems.
[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a submarine towing cable, which includes a core and a filling layer, the surface of the core is provided with a steel wire, the steel wire and the core are both located inside the filling layer, the surface of the filling layer is installed with an insulating layer, the surface of the insulating layer is installed with a braided layer, the surface of the braided layer is installed with a sheath, the surface of the sheath is installed with a waterproof layer, the surface of the waterproof layer is installed with a protective sleeve, the surface of the protective sleeve is provided with an anti-bite coating, and the surface of the protective sleeve is installed with a protective mesh sleeve.
[0008] As a preferred solution of the submarine towing cable of the utility model, the steel wires are arranged in a circular array and are evenly distributed around the wire core.
[0009] As a preferred solution of the submarine towing cable of the utility model, the insulating layer is made of rubber.
[0010] As a preferred solution of the submarine towing cable of the utility model, the protective tube sleeve is made of polyvinyl chloride material, and the anti-bite coating is a bitter acrylic ester compound.
[0011] As a preferred solution of the submarine towing cable of the utility model, the protective net sleeve is made of nylon.
[0012] Beneficial effects of the utility model:
[0013] 1. The utility model is provided with an anti-gnaw coating and a protective tube sleeve. When in use, the protective net sleeve made of nylon fiber can withstand greater tension and impact force to resist the bite of fish, thereby protecting the cable. Since it is installed on the surface of the anti-gnaw coating, it will be penetrated by the coating to attach a part of the odor on its surface. If the fish continues to bite, the protective net sleeve made of nylon fiber can resist the bite. Since the protective net sleeve is in a grid shape, it is easy to dissipate the odor of the anti-gnaw coating. When the fish bites the protective net sleeve, it will drive it to shake on the surface of the cable, which will accelerate the dissipation of the odor of the anti-gnaw coating. When the fish continuously smells the bitter acrylic ester compound, it will stay away from the cable, thereby reducing the risk of fish biting the cable.
[0014] 2. The utility model is provided with steel wire and a braided layer. When in use, the braided layer is made of high-strength fiber and is installed outside the insulating layer to increase the tensile strength of the cable, and can help the cable to evenly distribute the force when dragging, so as to avoid problems such as breakage when dragging. The steel wire ring array can make the cable have higher tensile strength and compressive strength, and can withstand greater tension and pressure to maintain the overall stability of the cable. It can also keep the cable flexible and bendable, which is convenient for installation and wiring, and can reduce damage to the cable due to twisting and dragging. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 1. Wire core; 2. Steel wire; 3. Filling layer; 4. Insulation layer; 5. Braided layer; 6. Sheath; 7. Waterproof layer; 8. Protective pipe sleeve; 9. Anti-bite coating; 10. Protective mesh sleeve. DETAILED DESCRIPTION
[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0020] Reference Figure 1 , which is the first embodiment of the utility model, provides a submarine towed cable, which includes a core 1 and a filling layer 3. The surface of the core 1 is provided with a steel wire 2, and the steel wire 2 and the core 1 are both located inside the filling layer 3. The surface of the filling layer 3 is provided with an insulating layer 4, the surface of the insulating layer 4 is provided with a braided layer 5, the surface of the braided layer 5 is provided with a sheath 6, the surface of the sheath 6 is provided with a waterproof layer 7, the surface of the waterproof layer 7 is provided with a protective sleeve 8, the surface of the protective sleeve 8 is provided with an anti-bite coating 9, and the surface of the protective sleeve 8 is provided with a protective mesh sleeve 10.
[0021] The steel wires 2 are arranged in a circular array and are evenly distributed around the core 1. The steel wires 2 are arranged in a circular array so that the cable has higher tensile strength and compressive strength, and can withstand greater tension and pressure to maintain the overall stability of the cable. The cable can also maintain flexibility and bendability, which is convenient for installation and wiring, and can reduce damage to the cable due to twisting and bending.
[0022] The insulating layer 4 is made of rubber material. Rubber has good flexibility and wear resistance, can provide good insulation protection, and can facilitate the cable dragging operation.
[0023] The protective tube sleeve 8 is made of polyvinyl chloride material, and the anti-bite coating 9 is a bitter acrylate compound with a very strong bitter taste. Once fish come into contact with the coating containing bitter acrylate, they usually feel uncomfortable, thereby reducing the biting behavior on the pipe. This method can protect the cable from damage by fish and extend the service life of the cable.
[0024] The protective net 10 is made of nylon, which can provide an additional layer of protection to prevent the cable surface from being physically damaged, worn or bitten. The protective tube sleeve 8 and the anti-bite coating 9 made of acrylic acid bitter ester compound can reduce the risk of the cable being bitten by fish.
[0025] By installing the steel wires 2 in a ring array around the wire core 1, a tight mesh structure can be formed between the steel wires 2, thereby improving the shear resistance and elongation at break of the steel wires 2. The steel wires 2 are made of galvanized steel wires, which have good corrosion resistance and can resist corrosion in seawater, thus extending the service life of the cable. At the same time, the cable can be protected when it is bent and stretched.
[0026] Rubber has good flexibility and elasticity. By installing the rubber insulating layer 4 on the surface of the filling layer 3, the flexibility and elasticity of the cable can be improved, thereby reducing the strain of the cable when it is stretched and preventing the cable from being damaged.
[0027] The braided layer 5 is made of high-strength fiber and is installed outside the insulating layer 4 to increase the tensile strength of the cable, which can help the cable to evenly distribute the force when dragging, so as to avoid problems such as breakage during dragging. The braided layer 5 has good wear resistance, which can increase the wear resistance of the cable and improve the service life of the cable.
[0028] The protective sleeve 8 is made of polyvinyl chloride material, which has insulation performance and corrosion resistance, can play a good protective role on the cable, prevent the cable from being polluted and corroded in a humid and dusty environment, and improve the service life of the cable. In addition, the protective sleeve 8 made of polyvinyl chloride material can improve the flexibility of the cable, making the cable more convenient to install and transport, and at the same time avoid damage to the cable caused by dragging;
[0029] By applying an anti-bite coating 9 of a bitter acrylate compound on the surface of the protective tube sleeve 8, the cable can have a pungent smell to drive away fish, thereby reducing the biting behavior of fish on the cable and further reducing the risk of fish biting the cable;
[0030] Nylon fiber has extremely high tensile strength and elastic modulus. The protective mesh 10 made of nylon fiber can withstand large tensile and impact forces. Since it is installed on the surface of the anti-gnaw coating 9, it will be penetrated by the coating to attach a part of the smell on its surface. If the fish continues to bite, the protective mesh 10 made of nylon fiber can resist the bite. Since the protective mesh 10 is in a grid shape, it is easy to dissipate the smell of the anti-gnaw coating 9. When the fish bites the protective mesh 10, it will drive it to shake on the surface of the cable, which will accelerate the dissipation of the smell of the anti-gnaw coating 9. When the fish continuously smells the bitter acrylic ester compound, it will stay away from the cable, thereby reducing the risk of fish biting the cable. In addition, nylon fiber has good wear resistance and can well prevent the cable surface from being rubbed and worn by objects such as bushes and stones, so as to protect the cable and achieve the purpose of increasing the service life of the cable.
[0031] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
