At the same time, the above-cited patent documents do not propose relevant solutions to solve the above problems.

[0005] Therefore, in order to solve the above problems, a high-strength wave-resistant underwater cable is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength wave-resistant water cable to solve the problems raised in the above-mentioned background technology.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] As attached Figure 1-4 A high-strength wave-resistant water cable is shown, comprising a cable body 5, the cable body 5 comprising a conductor 1, an insulating layer 2, a reinforcing filler 3, and a waterproof outer sheath 4. The conductor 1 is disposed inside the cable body 5, and an insulating layer 2 is disposed inside the cable body 5 near the outer wall of the conductor 1.

[0024] A reinforcement filler 3 is provided inside the cable body 5 near the outer wall of the insulating layer 2 , and a waterproof outer sheath 4 is provided on the outer wall of the cable body 5 .

[0025] Among them: the arrangement of the conductor 1 ensures the stability of the line when laid on water in the event of water surface fluctuations; the insulating layer 2 enables the cable body 5 to maintain excellent electrical insulation performance in moisture or water; at the same time, the reinforced filling 3 also enhances the strength and impact resistance of the cable body 5; the arrangement of the waterproof outer sheath 4 improves the water-blocking performance of the cable body 5 and further improves the wave impact resistance.

[0026] Example 2

[0027] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working methods. Figure 1-4 As shown, see the following description for details:

[0028] As a preferred embodiment, the cable body 5 has an elliptical shape, and the waterproof outer sheath 4 is tightly connected to the cable body 5; further, the elliptical appearance of the cable increases the contact area with water and improves the buoyancy of the cable. At the same time, when waves hit the cable from the side, the two sides of the ellipse can act as a diversion to disperse the waves, reduce the direct impact force of the waves on the cable, and make the cable line more stable during operation.

[0029] As a preferred embodiment, the conductor 1 is made of Class 6 tinned copper wire, and several groups of conductors 1 are arranged inside the cable body 5; further, when laid on water, the stability of the line is ensured when the water surface fluctuates. The conductor 1 adopts Class 6 tinned copper wire, which has good conductivity and softness, and can still maintain normal conductivity after bending. In addition, the tinned copper wire has better corrosion resistance than ordinary copper wire, ensuring that it will not be oxidized in humid environments.

[0030] As a preferred embodiment, the insulating layer 2 is made of polypropylene insulation, and the density of the insulating layer 2 is about 0.90 to 0.91 g / cm3; further, through the setting of the insulating layer 2 in the cable, the insulating layer 2 is particularly stable to water, and the water absorption rate in water is only 0.01%, and it can maintain excellent electrical insulation performance in moisture or water.

[0031] As a preferred embodiment, the insulating layer 2 is extruded around the outer wall of the conductor 1, and the thickness of the insulating layer 2 is approximately 0.7 mm. Furthermore, the insulating layer 2 is particularly stable to water, with a water absorption rate of only 0.01% in water, and can maintain excellent electrical insulation performance in moisture or water.

[0032] In a preferred embodiment, the reinforcing filler 3 is made of aramid fiber rope, extruded outside the insulating layer 2. Furthermore, the reinforcing filler 3 enhances the strength and impact resistance of the cable body 5. The aramid fiber material is stronger than steel wire, boasting exceptional strength while weighing only one-fifth of steel. The reinforcing filler 3 surrounds the cable core, significantly increasing its strength. Furthermore, the aramid fiber rope itself is relatively soft, providing a cushioning effect when the cable is subjected to impact, enhancing its impact resistance.

[0033] As a preferred embodiment, the waterproof outer sheath 4 is made of longitudinally wrapped polyester tape + high-density polyethylene, and the size of the waterproof outer sheath 4 is the same as that of the cable body 5. Further, the water-blocking performance of the cable body 5 is effectively improved. First, the longitudinally wrapped polyester tape can tighten the cable core to ensure the stability of the core-to-core structure. Second, when the longitudinally wrapped polyester tape is extruded with high-density polyethylene, it is subjected to high temperature and high pressure, and the overlapping parts will adhere to each other, forming a closed cylindrical shape that completely covers the internal cable core, preventing moisture from radially penetrating the cable. At the same time, the polyethylene material has a low water absorption rate. During extrusion, the high-temperature polyethylene and the polyester tape are tightly bonded, greatly improving the waterproof performance of the cable. High-density polyethylene has good chemical stability, physical and mechanical properties, and resistance to environmental stress cracking. Among them, the most important advantage is that it has low water absorption and a smooth surface with high hardness, which reduces the resistance to water flow when impacted by waves, further improving the wave impact resistance.

[0034] The working process of this utility model is as follows:

[0035] First, conductor 1 utilizes Category 6 tinned copper wire, which offers excellent conductivity and flexibility. It maintains normal conductivity even after bending. Tinned copper wire also offers superior corrosion resistance compared to ordinary copper wire, ensuring it will not oxidize in humid environments. Insulation layer 2 utilizes polypropylene, a material with a density of only 0.90-0.91 g / cm³. Polypropylene is particularly stable to water, with a water absorption rate of only 0.01%, maintaining excellent electrical insulation properties even in wet or submerged environments. A reinforced filler 3 is provided, made of aramid fiber rope. Aramid fiber surpasses steel wire in strength, boasting exceptional strength while weighing only one-fifth of steel. Filling the core with this fiber significantly enhances the cable's strength. The aramid fiber rope itself is relatively soft, providing a cushioning effect when impacted, improving the cable's impact resistance. A waterproof outer sheath 4 is constructed from a longitudinally wrapped polyester tape and high-density polyethylene. First, the longitudinal polyester tape can tighten the cable core, ensuring the stability of the core-to-core structure. Second, when the longitudinal polyester tape is extruded with high-density polyethylene, it is subjected to high temperature and high pressure, and the overlapping parts will adhere to each other, forming a closed cylindrical shape that completely covers the internal cable core and prevents moisture from radially penetrating the cable. At the same time, the polyethylene material has a low water absorption rate, and the high-temperature polyethylene and polyester tape are tightly bonded during extrusion, greatly improving the cable's waterproof performance. High-density polyethylene has good chemical stability, physical and mechanical properties, and resistance to environmental stress cracking. Among its main advantages, it has low water absorption and a smooth and hard surface, which reduces resistance to water flow when impacted by waves, further improving wave impact resistance, thus completing the use process of this high-strength wave-resistant offshore cable.

[0036] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
