[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a corrosion-resistant polyurethane cable, including a conductor 1, an insulating layer 2, an inner lining layer 3, a filler 4 and a sheath layer 5. The inner lining layer 3 is arranged outside the conductor 1, the insulating layer 2 is arranged outside the inner lining layer 3, the filler 4 is arranged between the insulating layer 2 and the sheath layer 5, and the sheath layer 5 is made of a polyester ammonia material.

[0025] The sheath layer 5 made of the polyester ammonia material has extremely high corrosion resistance and can resist the erosion of harsh environments such as strong acids, strong alkalis, and oil stains for a long time. At the same time, this material also has excellent electrical properties, heat resistance, cold resistance, and wear resistance, ensuring the long-term stable operation of the cable in harsh environments.

[0026] Furthermore, as shown in Figure 1 and Figure 2 , it is specifically noted that the conductor 1 is made of multi-strand ultra-fine precision-stranded oxygen-free copper wires, which have the advantages of high electrical conductivity, excellent mechanical properties, corrosion resistance, etc., and can ensure extremely low power loss during power transmission and improve the power transmission efficiency.

[0027] Furthermore, as shown in Figure 1 and Figure 2 , it is specifically noted that the thickness of the sheath layer 5 is 1.0 - 2.0 mm.

[0028] Furthermore, as shown in Figure 1 and Figure 2 , it is specifically noted that the filler 4 is made of a PVC core rope.

[0029] By selecting the PVC core rope as the filler 4 to fill the gap between the insulating layer 2 and the sheath layer 5, the overall structural stability of the cable is enhanced.

[0030] According to the above working process, it can be seen that: by using the sheath layer 5 made of corrosion-resistant polyurethane material, the cable can resist the erosion of harsh environments such as strong acids, strong alkalis, and oil stains for a long time. This material significantly extends the service life of the cable in complex environments and reduces the failure rate and replacement cost caused by corrosion.

[0031] Furthermore, as Figure 3 shown, it is specifically noted that the filler 4 is composed of a first polyester yarn 401, a second polyester yarn 402, and a hemp rope 403. The hemp rope 403 is disposed between the first polyester yarn 401 and the second polyester yarn 402. The first polyester yarn 401 is connected to the sheath layer 5, and the second polyester yarn 402 is connected to the insulating layer 2.

[0032] Through the filler 4 provided by the first polyester yarn 401, the second polyester yarn 402, and the hemp rope 403, when the cable is recycled, by pulling the conductor 1, the conductor 1 can form a tear between the first polyester yarn 401 and the hemp rope 403 under the pulling of the second polyester yarn 402 through the close arrangement with the insulating layer 2 and the inner lining layer 3, thereby facilitating the pulling out of the conductor 1 from inside the cable, making it convenient to recycle and reuse the cable after it is discarded.

[0033] Furthermore, as Figure 4 shown, it is specifically noted that the sheath layer 5 further includes a composite sheath layer 501. The composite sheath layer 501 is provided in one or more layers and is made of reinforced polyester fiber or nano-composite material or special coating.

[0034] By adding one or more composite sheath layers 501 on the basis of the specially made corrosion-resistant polyurethane sheath layer 5, these composite sheath layers 501 can select materials with different materials and functions, such as reinforced polyester fiber, nano-composite material, or special coating, etc. The multi-layer composite sheath design can not only further improve the corrosion resistance of the cable, but also enhance its anti-wear, anti-tear, and compressive properties, and improve the survival ability of the cable in extreme environments.

[0035] This solution has the following working process: The sheath layer 5 made of polyester ammonia material has extremely high corrosion resistance and can resist the erosion of harsh environments such as strong acids, strong alkalis, and oil stains for a long time. And through the setting of one or more composite sheath layers 501, materials with different materials and functions are selected, which can not only further improve the corrosion resistance of the cable, but also enhance its abrasion resistance, tear resistance and compressive resistance, improving the survival ability of the cable in extreme environments. And through the setting of the filler 4, it is used to fill the gap between the insulating layer 2 and the sheath layer 5, enhancing the overall structural stability of the cable. At the same time, for the filler 4 set by the first polyester yarn 401, the second polyester yarn 402 and the hemp rope 403, when the cable is recycled, by pulling the conductor 1, the conductor 1 can be torn between the first polyester yarn 401 and the hemp rope 403 under the pulling of the second polyester yarn 402 through the close setting with the insulating layer 2 and the inner lining layer 3, so as to facilitate pulling out the conductor 1 from inside the cable, making the cable easy to recycle and reuse after being discarded, which conforms to the concept of sustainable development.

[0036] In summary: By adopting the sheath layer 5 made of corrosion-resistant polyurethane material, the cable can resist the erosion of harsh environments such as strong acids, strong alkalis, and oil stains for a long time. This material significantly extends the service life of the cable in complex environments, reducing the failure rate and replacement cost caused by corrosion; By setting the filler 4, it can not only enhance the overall structural stability of the cable, but also facilitate pulling out the conductor 1 during the recycling process, thereby improving the recycling efficiency of the conductor 1 material, so that the cable can be easily recycled and reused after being discarded, which conforms to the concept of sustainable development.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
