Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a high-strength, aging-resistant shipboard cable. Background Technology

[0002] Shipboard cables are cable products specifically designed for use on ships and other watercraft to transmit electrical energy and signals, and to connect various electrical devices. They provide power support for various power equipment, lighting systems, and communication equipment on ships, ensuring their normal operation, and are responsible for transmitting various signals, including communication signals, control signals, and monitoring signals.

[0003] Chinese patent publication number CN218768819U discloses a cable core with an insulation layer on its exterior and an inner sheath on the exterior of the insulation layer. The outer sheath features an arc-shaped groove that limits the position of a rubber ring. The rubber ring and outer sheath are rotatably connected, and a paraffin coating reduces resistance between them. This design allows the rotation of the rubber ring to reduce impact force on the cable when subjected to heavy blows, thus improving the cable's impact resistance. The inner sheath has an outer mounting groove. The water-absorbing resin and high-density foam inside the groove absorb water when the cable is partially damaged. The expansion of the resin deforms the outer wall of the groove, sealing the leak and preventing the aging of the cable due to moisture.

[0004] The above-mentioned patent has the following shortcomings: the cable is prone to deformation, damage and other forms of corrosion from the external environment when it is pulled.

[0005] Therefore, we provide a high-strength, aging-resistant ship cable. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a high-strength, aging-resistant ship cable that is less prone to deformation and damage when stretched.

[0007] In view of this, the present invention provides a high-strength and aging-resistant ship cable, comprising a coating assembly, an armor assembly, an outer jacket assembly, an insulation assembly, and an inner core assembly.

[0008] The armor assembly includes aramid fibers and steel strips. The aramid fibers are disposed inside the coating assembly, and the steel strips are disposed inside the aramid fibers. The steel strips are spirally woven onto the outside of the outer jacket assembly.

[0009] Preferably, the outer sheath assembly includes a thermoplastic elastic sheath and a neoprene rubber sheath, the thermoplastic elastic sheath being disposed inside the steel strip, the neoprene rubber sheath being disposed inside the thermoplastic elastic sheath, and the inner side of the neoprene rubber sheath being installed and connected to the insulation assembly.

[0010] Preferably, the coating assembly includes an antifouling coating and an anticorrosion coating, the antifouling coating being disposed outside the anticorrosion coating, and the anticorrosion coating being disposed outside the steel strip in the armor assembly.

[0014] Compared with the prior art, this utility model provides a high-strength, aging-resistant ship cable, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of steel strip, enables the combined use of aramid fiber and steel strip. The steel strip adopts a composite armor structure combining spiral winding and braiding on the outer casing assembly. The outer braided aramid fiber and steel strip armor provide good compressive and tensile strength, preventing the cable from being damaged by external mechanical forces. At the same time, the outer braided aramid fiber enhances the cable's tensile and impact resistance. This composite structure can comprehensively improve the mechanical protection performance of the cable, adapt to the complex mechanical stress environment of ships, and thus make the cable less prone to deformation and breakage when pulled during use, increasing the cable's service life.

[0016] 2. This utility model, through the setting of a thermoplastic elastic sheath, allows the thermoplastic elastic sheath to be used in conjunction with a neoprene rubber sheath. The thermoplastic elastic sheath combines the high elasticity of rubber and the easy processing of plastic, and has excellent wear resistance and bending resistance. It can maintain good physical properties in the environment of frequent vibration and bending of ships, reducing the risk of outer sheath damage caused by mechanical stress and tension. At the same time, the neoprene rubber sheath has good oil resistance, water resistance and chemical corrosion resistance, and can effectively resist the erosion of seawater, oil and other pollutants, and has high mechanical strength and wear resistance.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
