Description

Technical Field

[0001] This utility model relates to the field of ship equipment and marine engineering technology, and in particular to high-strength wear-resistant cables for ships. Background Technology

[0002] In shipboard electrical systems, cables serve as the core carriers for power transmission and signal communication. Their performance directly affects the ship's navigation safety and combat effectiveness. However, the special working environment of ships places extremely stringent requirements on cables. Long-term exposure to high salt spray and high humidity environments can easily cause electrochemical corrosion of metal components. Ship vibration and equipment friction lead to frequent wear of cable sheaths and a high crack rate. During deep-sea or polar voyages, the wide temperature range of -40°C to 90°C can cause thermal expansion and contraction of materials, leading to insulation aging or conductor breakage. At the same time, the strong electromagnetic radiation from radar, communication and other equipment can easily cause signal interference, while the attachment of marine organisms such as barnacles can exacerbate local wear and poor heat dissipation.

[0003] Existing technologies for traditional ship cables suffer from multiple performance shortcomings: Abrasion resistance and strength are difficult to balance; for example, deep-water cables using neoprene sheaths, while possessing some water resistance, exhibit high abrasion rates in abrasion tests and have a lifespan of less than 1000 hours under high-frequency vibration. Some cables, while meeting strength standards, suffer from excessive rigidity, resulting in a bending radius ≥10 times the outer diameter, making them unsuitable for wiring in confined spaces. Protection systems are often simplistic, with most cables relying solely on a single layer of water-blocking tape or metal shielding, leading to a water penetration rate of up to 15% under water pressures above 10 bar and a corrosion rate exceeding 20% ​​for metal components after 5000 hours of salt spray testing. Intelligent maintenance capabilities are lacking, relying on periodic manual inspections, making it difficult to detect hidden damage (such as internal wire breaks or insulation aging), and troubleshooting takes over 24 hours, severely impacting ship availability. Furthermore, biofouling resistance is insufficient; in deep-sea environments, traditional sheaths can accumulate up to 60% of the cable surface area within 3 months, causing a 3-fold increase in localized wear rates.

[0004] As modern ships upgrade towards electrification and intelligence, the reliability requirements of cables for equipment such as radar and carrier-based aircraft have increased significantly. The passive protection, single performance optimization, and modes of traditional cables can no longer meet the needs. Therefore, developing a new type of ship cable with high strength, wear resistance, all-environment protection, intelligent monitoring, and self-repair functions has become the key to solving the existing technical bottlenecks. Utility Model Content

[0005] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a high-strength, wear-resistant cable for ships, which can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wear-resistant cable for ships, comprising nickel-plated soft copper wire, wherein the nickel-plated soft copper wire is provided with a conductor layer, a buffer layer, an insulation layer, an insulation film, a water-blocking layer, a water-blocking gap, a shielding layer, a reinforcing layer, a graphene film, an intelligent detection layer, a composite shielding layer, a sacrificial anode strip, a repair layer, a sheath layer, and an anti-biological coating arranged sequentially from the inside out.

[0007] Preferably, the stranding ratio of the nickel-plated soft copper wire in the conductor layer is 12-14 times, the single wire diameter of the nickel-plated soft copper wire is 0.5 mm, and the thickness of the nickel plating layer is 5-8 μm.

[0008] Preferably, the buffer layer is a composite structure of silicone rubber and metal corrugated pipe. The metal corrugated pipe is made of 316L stainless steel with a wall thickness of 0.1mm, and is spirally wound. The pipe is filled with highly elastic silicone rubber.

[0009] Preferably, the insulating layer is made of irradiated cross-linked ethylene propylene rubber, and the insulating film is a polyimide film wrapped around the outer periphery of the insulating layer.

[0010] Preferably, the water-blocking layer is an expanded water-blocking tape containing cross-linked sodium polyacrylate, the width of the water-blocking gap is 0.1 mm, and the shielding layer is an annealed copper strip, which is longitudinally welded to the periphery of the water-blocking gap.

[0011] Preferably, the reinforcing layer is made of composite yarn twisted together, the composite yarn containing 5% single-walled carbon nanotubes and 95% aramid fibers, and the graphene film has a thickness of 0.1 mm, covering the periphery of the reinforcing layer and filling its gaps.

[0012] Preferably, the intelligent detection layer comprises three distributed optical fibers with a diameter of 0.125 mm, which are uniformly distributed at 120° along the cable axis, and the surface of the optical fibers is engraved with Bragg gratings with a spacing of 0.5 mm.

[0013] Preferably, the anti-biological coating is a 0.1 mm thick cuprous oxide and graphene composite coating containing 5% cuprous oxide nanoparticles.

[0014] Preferably, the repair layer contains hollow glass microspheres, each microsphere encapsulating a two-component repair agent consisting of isocyanate and polyol in a 1:1 ratio.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The high-strength wear-resistant cable for ships combines the stress dispersion effect of carbon nanotubes, aramid stranded structure and graphene film in the reinforcing layer, which improves the impact resistance of the cable by 40% and can withstand the impact of 1000g instantaneous acceleration. At the same time, the bending radius is only 6 times the outer diameter, which solves the contradiction of being too rigid and too flexible. The composite design of silicone rubber and metal corrugated tube in the buffer layer extends the working temperature range to -55℃ to 150℃. With the double protection of water-blocking layer and sacrificial anode strip, the salt spray tolerance time is extended to 8000 hours, which is 60% higher than that of traditional cables, and is fully adapted to the extreme environment of ships with high salt spray and wide temperature variation.

[0017] (2) The ship uses a high-strength wear-resistant cable. The distributed optical fiber and composite shielding layer of the intelligent detection layer can monitor temperature, strain and electromagnetic interference in real time, realize millimeter-level fault location, and improve the fault response speed by 24 times. The hollow glass microbead repair agent of the repair layer is automatically released and solidified when damaged, and completes micro-damage repair within 30 minutes, restoring wear resistance to more than 80%. Combined with the 90% bio-adhesion inhibition rate of the anti-bio-coating, the maintenance cycle is extended by more than 3 times. This closed-loop design of active protection + intelligent early warning greatly reduces the fault risk of ship electrical system compared with the passive maintenance mode of traditional cables, and provides long-term safety guarantee for high-end ship equipment.

Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a high-strength wear-resistant cable for ships, including a nickel-plated soft copper wire 1, a conductor layer 2 is provided around the nickel-plated soft copper wire 1, a buffer layer 3 is provided around the conductor layer 2, an insulation layer 4 is provided around the buffer layer 3, and an insulation film 5 is provided around the insulation layer 4.

[0029] Conductor layer 2 wraps multiple stranded nickel-plated soft copper wires 1;

[0030] Nickel-plated soft copper wire 1 resists seawater corrosion due to its chemical inertness, while its multi-strand stranded structure reduces high-frequency signal transmission loss.

[0031] The buffer layer 3 is a composite structure of silicone rubber and metal bellows. The radial stress generated by the ship's vibration is offset by the helical elastic deformation of the metal bellows, which compensates for the thermal expansion and contraction of the conductor layer and avoids conductor stress fatigue fracture.

[0032] An insulating film 5 is surrounded by a water-blocking layer 6, a water-blocking gap 7 is surrounded by the water-blocking layer 6, a shielding layer 8 is surrounded by the water-blocking gap 7, a reinforcing layer 9 is surrounded by the shielding layer 8, and a graphene film 10 is covered around the reinforcing layer 9.

[0033] The water-blocking layer 6 is an expanding water-blocking tape containing cross-linked sodium polyacrylate, which together with the water-blocking gap 7 forms a gradient waterproof system. When seawater seeps in, the material of the water-blocking layer 6 expands within 3 seconds, filling the water-blocking gap 7 to form a gel seal.

[0034] The carbon nanotubes and aramid fibers in the reinforcing layer 9 are stranded together.

[0035] The reinforcing layer 9 adopts a carbon nanotube and aramid stranded structure, which forms a mechanical skeleton through cross stranding. The high elastic modulus of carbon nanotubes and the high breaking strength of aramid enhance the tensile strength of the cable. The graphene film 10 covering its periphery disperses local stress through interlayer sliding effect, and together with the reinforcing layer 9, it bears more than 90% of the tensile and impact loads, enabling the cable to withstand more instantaneous acceleration impacts.

[0036] A smart detection layer 11 is provided outside the graphene film 10. A composite shielding layer 12 is provided around the smart detection layer 11. A sacrificial anode strip 13 is provided around the composite shielding layer 12. A repair layer 14 is provided around the sacrificial anode strip 13. A sheath layer 15 is provided around the repair layer 14. An anti-biological coating 16 is provided around the sheath layer 15.

[0037] Working principle: The innermost nickel-plated soft copper wire 1 serves as the conductive core, with multiple strands twisted together to form the conductor layer 2. The nickel plating layer resists seawater corrosion due to its chemical inertness, while the multi-strand twisted structure reduces high-frequency signal transmission loss. The buffer layer 3 surrounding the conductor layer 2 is a composite structure of silicone rubber and metal bellows. The helical elastic deformation of the metal bellows offsets the radial stress generated by ship vibration. The internal silicone rubber filling layer contracts or expands during temperature changes from -55℃ to 150℃, compensating for the thermal expansion and contraction of the conductor layer and preventing conductor stress fatigue fracture. The insulating layer 4 outside the buffer layer 3 is radiation-crosslinked ethylene propylene rubber, which provides dielectric strength through a three-dimensional network crosslinking structure to block current leakage. The outer insulating film 5 is polyimide, which utilizes its resistance to partial discharge to prevent insulation aging during high-frequency signal transmission and ensures that the volume resistivity meets the standard at a long-term operating temperature of 90℃. The water-blocking layer 6 surrounding the membrane 5 is an expanding water-blocking tape containing cross-linked sodium polyacrylate, forming a gradient waterproof system with the water-blocking gap 7. When seawater seeps in, the material of the water-blocking layer 6 expands by ≥200% within 3 seconds, filling the water-blocking gap 7 to form a gel seal. Combined with the physical barrier of the longitudinally welded annealed copper strip of the outer shielding layer 8, it achieves 24 hours of no water leakage under 10 bar water pressure. At the same time, the shielding layer 8 acts as a grounding electrode to guide electromagnetic interference signals into the ship's grounding system. The reinforcing layer 9 surrounding the shielding layer 8 adopts a carbon nanotube and aramid stranded structure, forming a mechanical skeleton through cross-stretching. The high elastic modulus of carbon nanotubes and the high tensile strength of aramid enhance the tensile strength of the cable. The graphene film 10 covering it disperses local stress through interlayer sliding effect, and together with the reinforcing layer 9, it bears more than 90% of the tensile and impact loads, enabling the cable to withstand more instantaneous acceleration impacts.

[0038] The intelligent detection layer 11 on the outer side of the graphene film 10 contains three distributed optical fibers arranged at 120°. It monitors temperature and strain in real time via Bragg grating wavelength shift. When the local strain exceeds 2%, the signal is transmitted to the shipboard system to trigger an early warning. The surrounding composite shielding layer 12 is a copper-nickel alloy mesh + nanocrystalline ribbon. The alloy mesh enhances electromagnetic shielding, while the giant magnetoresistance effect of the nanocrystalline ribbon senses changes in the surrounding magnetic field, achieving dual monitoring of leakage current and strong electromagnetic radiation. The sacrificial anode strip 13 on the outer side of the composite shielding layer 12 is made of zinc-aluminum alloy. It preferentially corrodes seawater corrosive ions, protecting internal metal components and extending salt spray tolerance time. The repair layer 14 surrounding the sacrificial anode strip 13 contains a hollow core. Glass microspheres, containing a two-component repair agent of isocyanate and polyol, together with the sheath layer 15 (chloroprene rubber-shape memory polyurethane), form a wear-resistant self-repairing system. When the sheath layer 15 suffers damage ≥0.3mm deep due to friction or impact, the outer shell of the glass microspheres ruptures, releasing the repair agent. Under the catalytic effect of the high humidity environment on the ship, this agent solidifies within 30 minutes, forming an elastic sealing layer. The diamond-shaped pattern and PTFE wear-resistant strips on the surface of the sheath layer 15 further reduce the coefficient of friction and decrease continuous wear. The outermost bio-resistant coating 16 (cuprous oxide-graphene composite layer) slowly releases cuprous oxide nanoparticles to create an antibacterial environment, reducing the amount of barnacles and other organisms adhering to the cable by 90%, making it suitable for bio-rich environments such as deep seas and ports. Through a tightly connected structural design, each layer forms a complete closed loop of transmission, protection, monitoring, and repair, ensuring stable operation of the cable with high strength, wear resistance, and long service life in the extreme environment of the ship.

[0039] Structural Description:

[0040] Nickel-plated soft copper wire 1 is the conductive core of the cable, which is wrapped by conductor layer 2 after being twisted into multiple strands; function: as the basic carrier for current and signal transmission, it directly undertakes the function of power and data transmission; benefits: the nickel plating layer resists seawater corrosion due to its chemical inertness, the soft copper wire material ensures the flexibility of the conductor, and the multi-strand twisting design reduces high-frequency signal transmission loss and improves transmission efficiency.

[0041] Conductor layer 2 wraps multiple stranded nickel-plated soft copper wires 1 to form a bundle structure; function: to integrate the scattered nickel-plated soft copper wires into a unified conductive unit, enhancing the overall structural stability; benefits: the stranded bundle structure makes the conductor bend evenly, avoiding the breakage of a single copper wire, while expanding the conductive cross-section and reducing DC resistance.

[0042] The buffer layer 3 is a silicone rubber-metal corrugated tube composite structure, which is set on the periphery of the conductor layer 2. Its function is to counteract the radial stress generated by ship vibration and compensate for the expansion and contraction of the conductor layer due to temperature changes. Its advantages are that the spiral elastic deformation of the metal corrugated tube can absorb vibration energy, and the internal silicone rubber filling layer shrinks or expands when the temperature changes from -55℃ to 150℃, which prevents the conductor from breaking due to stress fatigue and widens the operating temperature range of the cable.

[0043] Insulation layer 4 is made of irradiated cross-linked ethylene propylene rubber and extruded around the buffer layer 3; function: to block current leakage and provide electrical insulation protection; benefits: the three-dimensional network cross-linked structure makes the dielectric strength ≥20kV / mm, can withstand the long-term working temperature of 90℃, and ensures stable volume resistivity and insulation performance in high humidity environment.

[0044] The insulating film 5 is made of polyimide and is wrapped around the outer perimeter of the insulating layer 4. Its function is to assist the insulating layer in enhancing its resistance to partial discharge and to protect the insulating layer from mechanical damage. Its benefits are that the partial discharge resistance (discharge amount ≤10pC) of the polyimide film can prevent insulation aging during high-frequency signal transmission, while its high-temperature resistance further improves the reliability of the insulation system.

[0045] The water-blocking layer 6 is an expandable water-blocking tape containing cross-linked sodium polyacrylate, which is placed around the insulating film 5. Its function is to expand rapidly upon contact with water to form a seal and prevent seawater from seeping into the internal structure. Its advantages are that the material has an expansion rate of ≥200% within 3 seconds, which can quickly fill gaps and form a gradient waterproof system with the water-blocking gap 7, thereby improving the longitudinal water-blocking capability of the cable.

[0046] The water-blocking gap 7 is a 0.1mm space reserved between the water-blocking layer 6 and the shielding layer 8; its function is to provide a buffer space for the expansion of the water-blocking layer 6, so as to avoid damage to the outer structure by the expansion pressure; its benefit is to prevent interlayer peeling caused by space limitation when the water-blocking layer expands, and to ensure the integrity of the waterproof seal.

[0047] The shielding layer 8 is a 0.15mm thick annealed copper strip, which is longitudinally welded to the periphery of the water-blocking gap 7 with an overlap rate of ≥15%; its function is to achieve both electromagnetic shielding and longitudinal watertightness; its advantage is that the sealed structure formed by the copper strip welding can remain watertight for 24 hours under 10 bar water pressure, and at the same time, it serves as a grounding electrode to guide electromagnetic interference signals into the ship's grounding system.

[0048] The reinforcing layer 9 is composed of carbon nanotubes and aramid fibers in a stranded structure and is set around the shielding layer 8. Its function is to serve as the "mechanical skeleton" of the cable, improving the overall tensile strength and impact resistance. Its benefits are that the high elastic modulus of carbon nanotubes and the high breaking strength of aramid fibers combine to increase the cable's tensile strength to 18kN / m. The cross-stretched structure can disperse more than 90% of the tensile and impact loads and withstand 1000g instantaneous acceleration impact.

[0049] A graphene film 10 covers the periphery of the reinforcing layer 9, filling its gaps; its function is to disperse local stress and enhance the overall stress uniformity of the reinforcing layer; its benefits are that the interlayer sliding effect of graphene can reduce the stress concentration factor, and together with the reinforcing layer, further improve the fatigue resistance of the cable and extend its service life.

[0050] The intelligent detection layer 11 contains three distributed optical fibers arranged at 120° along the axis and is located on the outside of the graphene film 10. Its function is to monitor the temperature and strain of the cable in real time and realize fault early warning. Its benefits are that temperature and strain can be accurately monitored by the wavelength shift of the Bragg grating. When the local strain exceeds 2%, the shipborne system will be triggered to provide an early warning, realizing millimeter-level fault location and improving the fault response speed by 24 times.

[0051] The composite shielding layer 12 is a composite structure of copper-nickel alloy mesh and 0.02mm thick nanocrystalline ribbon, and is set on the periphery of the intelligent detection layer 11. Its function is to enhance electromagnetic shielding performance and monitor leakage current and external strong electromagnetic radiation. Its benefits are that the alloy mesh improves shielding efficiency and the giant magnetoresistance effect of the nanocrystalline ribbon can sense changes in the magnetic field, thus realizing dual electromagnetic protection and safety monitoring.

[0052] The sacrificial anode strip 13 is a 0.2mm thick zinc-aluminum alloy strip wrapped around the outer perimeter of the composite shielding layer 12. Its function is to consume corrosive ions from seawater through preferential corrosion, thus protecting the internal metal components. Its benefits are that the corrosion rate of the zinc-aluminum alloy is ≤0.1mm / year, which can extend the salt spray tolerance time of the cable to 8000 hours and reduce the corrosion risk of metal components.

[0053] Hollow glass microspheres are distributed within the repair layer 14, each encapsulating a two-component repair agent consisting of isocyanate and polyol, and are positioned around the periphery of the sacrificial anode strip 13. Function: Automatically releases the repair agent when the sheath layer is damaged, achieving self-repair of micro-damage. Benefits: When the sheath layer suffers damage ≥0.3mm deep, the glass microspheres rupture, releasing the repair agent, which cures within 30 minutes under high humidity catalysis, restoring wear resistance to over 80% and reducing maintenance frequency.

[0054] The sheath layer 15 is a neoprene rubber-shape memory polyurethane interpenetrating network structure with a diamond pattern on the surface. Polytetrafluoroethylene wear-resistant strips are embedded in the grooves and it is set around the repair layer 14. Its function is to provide outer wear-resistant protection and work with the repair layer to achieve damage repair. Its benefits are that the composite structure has a Shore hardness of 75±3A, and the diamond pattern and wear-resistant strips reduce the coefficient of friction to 0.25, reducing continuous wear and extending the life of the sheath.

[0055] The anti-biodegradation coating 16 is a 0.1mm thick cuprous oxide-graphene composite layer coated on the outer periphery of the sheath layer 15; its function is to inhibit the attachment of marine organisms such as barnacles and reduce wear caused by biological erosion; its benefits are that the annual release rate of cuprous oxide nanoparticles is ≤10%, forming a long-lasting antibacterial environment, reducing the amount of biological attachment by 90%, and making it suitable for deep-sea, port and other biologically rich environments.
