[0017] Referring to Figures 1 to 4 As shown, the present invention provides an anti-corrosion composite cable, including: an auxiliary cable core 1 and an inner protective layer 2. The outer side of the auxiliary cable core 1 is fixedly connected to the inner protective layer 2, and the outer side of the inner protective layer 2 is fixedly connected to the outer protective layer 3. The auxiliary cable core 1 is composed of an inner core 4 and a corrosion-resistant layer 5, and the surface of the inner core 4 is fixedly connected to the corrosion-resistant layer 5. The inner protective layer 2 is composed of an insulation layer 6, a waterproof layer 7 and an antibacterial layer 8. The insulation layer 6 is fixedly connected to the outer side of the auxiliary cable core 1, and the outer side of the insulation layer 6 is fixedly connected to the waterproof layer 7. The outer side of the waterproof layer 7 is fixedly connected to the antibacterial layer 8. At the same time, the outer protective layer 3 is composed of a heat-resistant layer 9 and a sheath layer 10. The heat-resistant layer 9 is fixedly connected to the outer side of the inner protective layer 2, and the outer side of the heat-resistant layer 9 is fixedly connected to the sheath layer 10.

[0018] In this embodiment, a corrosion-resistant layer 5 is first coated on the surface of the inner core 4, and then three groups of inner cores 4 are twisted into strands to form the supporting sub-cable core 1. The insulating layer 6 is wrapped around the outer surface of the sub-cable core 1 by extrusion, which can assist in enhancing the overall structural strength and stability of the sub-cable core 1. The waterproof layer 7 is wound around the outer surface of the insulating layer 6 by lapping, and one side of the aluminum foil tape used for the waterproof layer 7 is superimposed on the other side surface, thereby enhancing the waterproof and moisture-proof effect of the waterproof layer 7 and also being able to achieve a good light-shielding effect. When the antibacterial layer 8 is fixed on the outer surface of the waterproof layer 7 by weaving, it can not only assist in enhancing the winding stability of the waterproof layer 7 but also reduce the probability of the waterproof layer 7 being worn. Then, the three groups of sub-cable cores 1 are helically wound around each other to form the main cable core, which can effectively enhance the overall structural strength of the cable and also avoid the problem of the overall structure becoming loose due to the fracture of a single inner core 4. At the same time, the heat-resistant layer 9 woven on the outer surface of the main cable core can effectively improve the heat-resistant effect on the surface of the cable, and the sheath layer 10 woven on the outer surface of the heat-resistant layer 9 can effectively enhance the overall abrasion resistance of the cable, and the outer protective layer 3 can also assist in enhancing the overall structural stability of the main cable core.

[0019] As a preferred embodiment, the sub-cable core 1 is made by twisting three groups of inner cores 4 into strands. All three groups of inner cores 4 are made of steel wire, and a corrosion-resistant layer 5 is coated on the outer surface of all three groups of inner cores 4. The corrosion-resistant layer 5 is made of epoxy asphalt.

[0020] In this embodiment, as Figure 1 and Figure 2 , the sub-cable core 1 is made by twisting three groups of inner cores 4 into strands, which can effectively enhance the structural strength of the sub-cable core 1, and a corrosion-resistant layer 5 is coated on the surface of each inner core 4, thereby effectively enhancing the overall corrosion resistance of the sub-cable core 1.

[0021] As a preferred embodiment, the insulating layer 6 is made of soft rubber, and the insulating layer 6 is wrapped around the outer side of the sub-cable core 1 by extrusion.

[0022] In this embodiment, as Figure 3 , the setting of the insulating layer 6 can not only assist in enhancing the overall structural strength of the sub-cable core 1 but also enhance the insulation and waterproof effect of the sub-cable core 1, and at the same time can also assist in enhancing the anti-impact effect of the sub-cable core 1, effectively extending the service life of the sub-cable core 1.

[0023] As a preferred embodiment, the waterproof layer 7 is made of aluminum foil, and the aluminum foil tape is evenly wound around the outer surface of the insulating layer 6 by lapping.

[0024] In this embodiment, as Figure 3, the aluminum foil tape is light in weight, has no thermal adhesiveness, good light-shielding property, strong light reflection ability, is not easily corroded, has good barrier property, moisture-proof and waterproof performance, and strong airtightness. Therefore, it can further enhance the corrosion resistance and moisture-proof and waterproof effects of the auxiliary cable core 1, and reduce the probability of the auxiliary cable core 1 contacting water vapor.

[0025] As a preferred embodiment, the antibacterial layer 8 is made of nylon fiber material, and the nylon fiber is fixedly connected to the outer surface of the waterproof layer 7 by weaving.

[0026] In this embodiment, as Figure 3 , silver ion ceramic material is mixed in the nylon spinning process, which will release trace amounts of silver ions, and then achieve a good antibacterial effect, and then can effectively prevent bacteria from growing inside the cable, thereby reducing the probability of corrosion inside the cable.

[0027] As a preferred embodiment, there are three groups of auxiliary cable cores 1 in total. The three groups of auxiliary cable cores 1 are helically wound around each other to form the main cable core, and the heat-resistant layer 9 fixedly connected to the outer surface of the main cable core is made of glass fiber material.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the three groups of auxiliary cable cores 1 wound around each other can assist in enhancing the structural strength of the main cable core, and the setting of the heat-resistant layer 9 can effectively enhance the overall heat-resistant effect of the cable, ensure that the cable can be exposed to sunlight for a long time, and also play a certain fireproof effect.

[0029] As a preferred embodiment, the sheath layer 10 is made of polyester fiber material, and the polyester fiber is woven on the outer side of the heat-resistant layer 9.

[0030] In this embodiment, as Figure 1 and Figure 4 , the setting of the sheath layer 10 makes the outer surface of the cable have good wear resistance, so as to provide good protection for the internal structures of the cable.

[0031] The anti-corrosion composite cable for ships of the present invention, through the cooperation of the inner protective layer 2 and the outer protective layer 3, enables the auxiliary cable core 1 to have a multi-layer protection structure, thereby effectively enhancing the overall anti-corrosion effect of the cable, and ensuring the stability of the cable when exposed to wind and sunlight at sea.
