Technical Field

[0002] Pre-stranded wire sheaths are used to protect conductors from vibration, clamp stress, friction, electric arcs, and all other external damage. Pre-stranded short wire sheaths can protect conductors from electric arcs, friction, or other damage over short spans when conductor vibration is not severe. They can also be used as repair strips to repair damaged conductors, restoring them to their original mechanical strength and conductivity. They can also be used to protect branch lines, preventing damage to conductor branch points caused by electric arcs and friction. Pre-stranded wire sheaths and pre-stranded short wire sheaths have a simple structure; a set of pre-stranded wires forms a hollow tube that wraps around the conductor, creating a gripping force to protect it. Therefore, a corrosion-resistant pre-stranded armored wire sheath is needed.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-4 A corrosion-resistant pre-stranded armored protective line includes a core 1, an inner protective layer 2 wrapped around the outer wall of the core 1, inner aramid fibers 3 wrapped around the outer wall of the inner protective layer 2, an inner adhesive layer 4 coated around the outer wall of the inner aramid fibers 3, a waterproof layer 5 adhered to the outer wall of the inner adhesive layer 4, an outer adhesive layer 6 coated around the outer wall of the waterproof layer 5, outer aramid fibers 7 adhered to the outer wall of the outer adhesive layer 6, and an outer protective layer 8 wrapped around the outer wall of the outer aramid fibers 7. Both the outer aramid fibers 7 and the inner aramid fibers 3 are arranged in a mesh pattern, and the inner aramid fibers 3 are movably connected to the inner protective layer 2. The surface of the waterproof layer 5 is tightly adhered to the outer wall of the inner aramid fibers 3 and the inner wall of the outer aramid fibers 7, and the waterproof layer 5 is glued to the inner aramid fibers 3 and the outer aramid fibers 7. Through the mesh pattern of the inner aramid fibers 3 and the outer aramid fibers 7, external forces can be effectively dispersed, improving the tensile strength and shear resistance of the protective line. The waterproof layer 5 can prevent water from seeping into the core 1 and causing damage.

[0026] Please see Figure 1-4A corrosion-resistant pre-stretched armored protective line has an outer protective layer 8 coated with a zinc-nickel alloy coating 9. A collar 10 is installed on the outer wall of the outer protective layer 8, and a temperature detector 11 is installed on the outer wall of the collar 10. A fixing bolt 12 passes through the interior of the temperature detector 11. The zinc-nickel alloy coating 9 is tightly bonded to the surface of the outer protective layer 8 and is also adhesively bonded to the outer protective layer 8. The collar 10 is pressed into the outer protective layer 8, and the temperature detector 11 is threadedly connected to the collar 10. Through the zinc-nickel alloy coating 9 on the outer protective layer 8, the metal substrate is prevented from being corroded through electrochemical protection, enhancing the corrosion resistance of the protective line. Furthermore, by monitoring the temperature changes of the protective line through the temperature detector 11, the working environment of the protective line can be understood in a timely manner, and an alarm can be issued when the temperature is abnormal, reminding the staff to take appropriate measures, such as cooling the protective line in high-temperature environments or providing anti-corrosion and moisture-proof protection for the protective line in low-temperature environments.

[0027] Please see Figure 1-4 A corrosion-resistant pre-stretched armored protective line has a first connector 13 installed on the outer wall of the outer protective layer 8, a second connector 14 installed on the inner wall of the first connector 13, a sleeve post 15 installed on the outer wall of the second connector 14, a spring 16 installed on the inner wall of the sleeve post 15, a spring 16 installed on the outer wall of the spring 16, and a buckle 17 provided on the outer wall of the second connector 14. The first connector 13 and the second connector 14 are pressed against the outer protective layer 8 and are engaged. The buckle 17 is movably connected to the sleeve post 15, and the buckle 17 forms a telescopic structure with the sleeve post 15 through the spring 16. When it is necessary to connect the two sections of the protective line, simply press the buckle 17 on the second connector 14 of one end of the protective line and insert it into the first connector 13 on the other end of the protective line. The buckle 17 is fixed by the spring 16, which facilitates the connection of the two sections of the protective line. At the same time, the first connector 13 and the second connector 14 can protect the break points at the connection points of the protective lines.

[0028] Working Principle: In use, first assemble the device. Insert the core 1 into the inner protective layer 2, then cover it with the inner aramid fiber 3, then adhere the inner adhesive layer 4 to the inner aramid fiber 3, then adhere the waterproof layer 5 to the inner aramid fiber 3, then adhere the outer adhesive layer 6 to the waterproof layer 5, then adhere the outer aramid fiber 7 to the waterproof layer 5, then wrap the waterproof layer 5 around the outer aramid fiber 7, and finally apply a coating to the outer protective layer 8. Simultaneously, fix the temperature detector 11 to the outer protective layer 8 using fixing bolts 12. Then, put it into use. During use, the mesh-like structure of the inner aramid fiber 3 and outer aramid fiber 7 effectively disperses external forces, allowing stress to be evenly distributed throughout the fiber mesh when subjected to different types of forces such as tension, bending, or compression. When water flows onto the device… The waterproof layer 5 prevents water from seeping into the wire core 1. At the same time, the temperature detector 11 is activated to detect the temperature of the device, preventing high temperature from causing corrosion and low temperature from causing moisture. When it is necessary to connect the other end of the protective line, the first connector 13 and the second connector 14 are pressed onto the two sections of the protective line. Simply press the buckle 17 on the second connector 14 by hand. The buckle 17 is compressed by the spring 16, which retracts the buckle 17. Then, the second connector 14 is inserted into the first connector 13. Then, release your hand and push the buckle 17 into the hole provided on the first connector 13. The buckle 17 is fixed in place by the spring 16. This completes the use of the device.
