[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0032] Reference Figures 1 to 7As shown, wires and cables are necessary electrical equipment for transmitting electric energy and are the only route for electric energy to flow. They are widely used in various fields such as petroleum, chemical industry, metallurgy, power generation, ships, railways, tunnels, aerospace, construction, mining, housing, hospitals, schools, etc. These fields have high requirements for various indicators of wires and cables, such as chemical corrosion resistance, cold resistance, high temperature resistance, good insulation performance, good mechanical properties, anti-aging, softness, halogen-free low-smoke flame retardant, good conductivity, energy saving and low consumption, and more importantly, the characteristics of ensuring safety and environmental protection. The conductor materials that people are accustomed to using for wire and cable products are copper and aluminum, of which the use of copper conductors accounts for more than 80% of the total amount of wire and cable products. In addition, copper used in other industrial production also accounts for more than 90% of the total copper used in the country. With the rapid development of my country's economic construction, the use of copper in industrial production is increasing year by year. my country's copper resources are scarce. At the same time, my country is a major copper-consuming country. More than 80% of the copper demand is met by imports. Therefore, energy conservation and consumption reduction have attracted the attention of the whole society. At present, domestically produced wire and cable products consume a large amount of copper, and domestic copper resources are scarce. There is a great risk in relying on imported copper. In addition, ordinary aluminum conductor wires and cables have poor performance and low flame retardant properties. When burned by flames in a fire, hydrogen chloride gas and halogen harmful substances are released, causing "secondary disasters" to the victims in the fire and unable to maintain effective power transmission in the fire.If the wire and cable with aluminum conductor has poor anti-aging performance and weak anti-overload capacity of the line, the line overload short circuit will cause a short circuit to the ground, causing the line to burn and lead to a fire. In order to solve this problem, a power-saving, fire-proof and anti-aging copper alloy wire is proposed, including a copper alloy cable 1, the copper alloy cable 1 includes a plurality of cable cores 101 and a plurality of copper alloy conductive wire cores, a high-silica fiber belt is arranged on the outside of the high-silica fiber belt, and a flame-retardant polyester film layer, an aluminum-plastic composite belt layer, and a metal shield are arranged on the outside of the high-silica fiber belt in sequence. The outer walls of the plurality of cable inner cores 101 are all sleeved with cable protective sleeves 102, the outer walls of the cable protective sleeves 102 are sleeved with a heat-insulating flame-retardant layer 103, the outer walls of the heat-insulating flame-retardant layer 103 are sleeved with an insulating coating layer 104, the outer walls of both ends of the copper alloy cable 1 are sleeved with protective members 2, an adjusting mechanism 3 is rotatably installed between the protective members 2 at both ends, one side of the adjusting mechanism 3 is rotatably connected with a reinforcing member 4, the protective member 2 includes a protective member sleeved on the outer wall of the insulating coating layer 104 The outer shell 21 has a plurality of first arc grooves 22 formed inside the protective outer shell 21, and a plurality of second arc grooves 23 formed on the outer wall of the protective outer shell 21, and filter plates 24 are fixedly installed inside the plurality of second arc grooves 23, and a plurality of protective cover plates 25 are hingedly connected to the outer wall of the protective outer shell 21; by arranging a plurality of protective cover plates that can be opened and closed on the outer wall of the insulating coating layer, the heat generated inside and outside the insulating coating layer can circulate with the outside air, thereby avoiding the heat from always accumulating on the insulating coating layer, and making it easier to dissipate the heat generated by the copper alloy cable as a whole in time, thereby avoiding the problem of the internal temperature of the copper alloy cable as a whole being too high and being damaged, and by squeezing the sealing rubber ball, a gap can be generated between the connecting groove and the sealing rubber ball, thereby exposing the lubricating oil to be coated on the surface of the protective outer shell and the protective cover plate, thereby playing a role in lubricating and protecting the surface of the protective outer shell and the protective cover plate, thereby avoiding the problem of sunburn and aging on the surface of the protective outer shell and the protective cover plate, thereby greatly improving the strength and anti-aging performance of the wires and cables.

[0033] It should be noted that the protective member 2 includes a protective shell 21 sleeved on the outer wall of the insulating coating layer 104, a plurality of first arc grooves 22 are provided inside the protective shell 21, a plurality of second arc grooves 23 are provided on the outer wall of the protective shell 21, and a filter plate 24 is fixedly installed inside the plurality of second arc grooves 23. The purpose of such arrangement is to allow a cavity to exist between the outside and the insulating coating layer 104, and to allow the filter plate 24 in the cavity to be ventilated and isolated from the outside, so that the heat inside the filter plate 24 can be discharged through the filter plate 24, and the external cold air can also enter through the filter plate 24. Enter the inner cavity of the first arc groove 22, and perform heat exchange treatment on the heat generated by the outer wall of the insulating coating layer 104 in turn, so as to avoid the heat always accumulating on the outer wall of the insulating coating layer 104, affecting the actual use of the copper alloy cable 1 as a whole. At the same time, the outer wall of the protective shell 21 is hinged with multiple protective cover plates 25. When there is no need to cool down the copper alloy cable 1 as a whole, the second arc groove 23 and the filter plate 24 can be blocked by multiple protective cover plates 25, so that the protective shell 21 combined with the protective cover plates 25 can be used normally to enclose the outer wall of the insulating coating layer 104 for protection.

[0034] Further, on the basis of the above, considering the special use occasions of copper alloy cables, especially the use in the high temperature and radiation environment of nuclear power plants, in order to further improve the heat dissipation effect of wires and cables, multiple first arc grooves 22 and filter plates 24 are arranged in a one-to-one correspondence state, and multiple first arc grooves 22 and filter plates 24 are arranged in a circular and equidistant state in sequence around the circumferential surface of the protective shell 21 as a trajectory. The purpose of such a setting is to allow the internal and external temperatures to be evenly heat exchanged through the multiple first arc grooves 22, so that the temperature of the outer wall of the insulating coating layer 104 is more uniform, avoiding uneven heating and then damage. At the same time, refer to Figure 5 As shown, multiple protective cover plates 25 are arranged in a one-to-one correspondence with the second arc groove 23. A magnetic strip 26 is fixedly installed on one side of the protective cover plate 25, and an arc-shaped magnetic protective cover 27 is fixedly installed on the outer wall of the protective shell 21. The magnetic strip 26 is clamped in the inner cavity of the arc-shaped magnetic protective cover 27. The purpose of this arrangement is that when multiple protective cover plates 25 are blocked at the second arc groove 23, the mutual engagement of the magnetic strip 26 and the arc-shaped magnetic protective cover 27 can make the installation of the protective cover plate 25 more secure, thereby preventing the protective cover plate 25 from being impacted by external force and opening the second arc groove 23 during use. At the same time, the hinge between the protective cover plate 25 and the protective shell 21 and the outer wall of the magnetic strip 26 are covered with a water-swellable rubber pad. The purpose of this arrangement is that when encountering rainy weather, rainwater will not leak into the interior of the first arc groove 22.

[0035] In addition, the design of the high flame retardant and fireproof function of the copper alloy wire in the present invention is that the copper alloy conductor is covered with a fireproof phlogopite layer in the product structure, and then covered with a halogen-free low-smoke flame-retardant ceramicized polyolefin insulation coating layer and a high-temperature flame-retardant and fireproof quartz cloth and a high-temperature flame-retardant high-silica fiber layer, so that the high flame retardant and fireproof performance, insulation performance, overload resistance and aging resistance are more prominent. The fireproof phlogopite, high-temperature flame-retardant and fireproof quartz cloth and high-temperature flame-retardant high-silica fiber materials used in the product are not only non-toxic and odorless, but also have good physical and mechanical properties, good chemical resistance and good processability. Under high temperature and flame ablation above 1200℃, high temperature flame retardant fireproof quartz cloth, high temperature flame retardant high silica fiber material and halogen-free low smoke flame retardant ceramic polyolefin insulation components will be ablated and converted into hard solidified substances in a very short time, forming a good heat insulation layer on the surface of the wire and cable conductor to prevent the continued burning of the flame. Moreover, the longer the ablation time and the higher the temperature, the more obvious the hardening effect of the solidified substance, so that the wire and cable can still transmit electricity normally when placed on the flame. No harmful hydrogen halide gas and smoke are produced during combustion, which improves the visibility of the fire scene, effectively wins time for fire rescue, and creates an escape opportunity for the victims of the fire.

[0036] This solidified material after high temperature combustion can reach a fire resistance of 1200℃, so that the cable can still maintain normal operation in the combustion environment; at the same time, no ash remains after burning. It really plays a good role in fire fighting, fire prevention and safety and environmental protection. The aluminum-plastic composite tape and metal shielding layer inside the product structure play an anti-interference and moisture-proof role. The halogen-free low-smoke flame-retardant silicone rubber is soft and elastic as a protective layer for the internal insulator to prevent it from mechanical damage by external forces and also enhance the flame retardant effect.

[0037] It should also be noted that the above-mentioned structure cannot be opened smoothly because the protective cover 25 is fixed to the rotating pressure plate 37 during the deflection process, and thus the heat dissipation cannot be smoothly performed. In order to further stably drive the protective cover 25 to deflect and improve the uniformity of heat dissipation, the present embodiment has an annular sleeve 28 fixedly connected to both ends of the protective shell 21, and the adjustment mechanism 3 includes an annular groove 31 provided on the outer wall of the annular sleeve 28, and a plurality of connecting slides 32 are slidably installed on the outer wall of the annular groove 31, and a connecting ring 33 is fixedly connected between the plurality of connecting slides 32, so that the plurality of connecting slides 32 can synchronously rotate on the outer wall of the annular groove 31, and at the same time, the plurality of connecting slides The bottom of each connecting slide plate 32 is fixedly installed with an arc-shaped serrated plate 34, and the bottom of the arc-shaped serrated plate 34 is meshed with a gear plate 35 rotatably connected to the annular sleeve 28. A rotating rod 36 is fixedly connected to one side of the gear plate 35, and a rotating pressure plate 37 hinged to the protective cover plate 25 is fixedly installed on the outer wall of the rotating rod 36. The purpose of this arrangement is that when the connecting slide plate 32 is rotated as a whole, the displacement of the arc-shaped serrated plate 34 can drive the gear plate 35 to rotate, and then the rotating rod 36 drives the rotating pressure plate 37 as a whole to deflect the protective cover plate 25 as a whole, thereby exposing the second arc groove 23, so that the inside and outside of the first arc groove 22 are ventilated and heat-dissipated, wherein, with reference to Figure 3 As shown, the outer walls of the plurality of protective cover plates 25 are provided with limit grooves 38, and the interiors of the plurality of limit grooves 38 are slidably installed with guide slide columns 39 hinged to the rotating pressure plate 37, and the plurality of guide slide columns 39 are fixedly connected with connecting ring sleeves 310. The purpose of such a setting is that in the process of the deflected rotating pressure plate 37 driving the protective cover plate 25 to deflect and open, the guide slide columns 39 can slide in the inner cavity of the limit groove 38, thereby further stably driving the protective cover plate 25 to deflect, thereby avoiding the problem that the protective cover plate 25 cannot be smoothly opened during the deflection process due to being fixed to the rotating pressure plate 37. At the same time, through the setting of the connecting ring sleeve 310, the plurality of rotating pressure plates 37 can be synchronously offset, and then the plurality of second arc grooves 23 are synchronously exposed, so that the heat emitted through the second arc grooves 23 is more uniform, and thus the temperature of the insulating coating layer 104 is more uniform.

[0038] Furthermore, considering the strength and anti-aging requirements of the copper alloy cable, on the basis of the above embodiment, the reinforcement member 4 includes a connecting rod 41 rotatably installed on one side of the connecting slide 32, and the connecting rod 41 and the connecting slide 32 and the rotating pressure plate 37 are arranged in a one-to-one correspondence, and multiple connecting rods 41 are arranged on the outer wall of the rotating pressure plate 37. The purpose of this arrangement is to synchronously drive the connecting rod 41 to move when the connecting slide 32 is rotated, and then when the connecting rod 41 moves to the outer wall of the rotating pressure plate 37, the rotating pressure plate 37 can be limited, so that the protective cover plate 25 is again blocked at the second arc groove 23. The blocking of the protective cover plate 25 is more firm. At the same time, referring to Figure 6 and Figure 7 As shown, a rotating drum 42 is fixedly installed on the outer wall of the connecting rod 41, and a plurality of storage barrels 43 are fixedly installed in a circular shape and equidistantly in sequence in the inner cavity of the rotating drum 42 around the outer circumferential surface of the connecting rod 41, and the plurality of storage barrels 43 are linearly and equidistantly arranged in sequence along the horizontal direction of the outer wall of the rotating drum 42, a conducting groove 44 is provided inside the storage barrel 43, and a connecting groove 45 connected to the conducting groove 44 is provided at one end of the storage barrel 43 close to the outer wall of the rotating drum 42.

[0039] It is worth mentioning that the inner diameter length of the connecting groove 45 is greater than the inner diameter length of the conducting groove 44, and the inner cavity of the connecting groove 45 is provided with a sealing rubber ball 46, and the outer wall of the sealing rubber ball 46 is fixedly installed with a tension spring 47 fixedly connected to the storage barrel 43. Under normal conditions, the tension spring 47 is in an expanded state to push the sealing rubber ball 46 to the connecting groove 45, so that the care oil inside the storage barrel 43 cannot be discharged to the outer surface of the protective shell 21 or the protective cover 25 through the connecting groove 45. When the connecting slide 32 is turned to adjust so that the protective cover 25 is opened, the connecting rod 41 can synchronously drive the rotating drum 42 It moves on the surface of the protective cover 25 and the protective shell 21, and then when the outer wall of the rotating drum 42 comes into contact with the surface of the protective shell 21 or the protective cover 25, it can produce pressure on the sealing rubber ball 46, and then squeeze and contract the tension spring 47, so that a gap is generated between the sealing rubber ball 46 and the connecting groove 45, and then the care oil in the inner cavity of the conducting groove 44 can be coated on the outer surface of the protective shell 21 and the protective cover 25, so as to care for the outer wall of the protective shell 21 and the protective cover 25, and avoid the problem of cracks and drying on the surface of both due to long-term exposure to the sun, thereby greatly improving the strength and anti-aging performance of the wires and cables.

[0040] In addition, in the specific implementation, the protective cover plate 25 is first covered and sealed at the second arc groove 23, so that the copper alloy cable 1 can be used for normal communication transmission as a whole. When the temperature of the copper alloy cable 1 is too high, by rotating the connecting slide plate 32, the arc-shaped sawtooth plate 34 can synchronously drive the gear plate 35 to deflect, and then the rotating rod 36 and the rotating pressure plate 37 can synchronously drive the protective cover plate 25 to deflect, exposing the second arc groove 23, so that the heat inside the copper alloy cable 1 is discharged through the filter plate 24 for heat dissipation treatment, thereby reducing the temperature of the surface of the insulating coating layer 104, and then reducing the temperature of the inner core of the cable. 101, at the same time, the rotating connecting slide plate 32 synchronously drives the connecting rod 41 and the rotating drum 42 to move on the surface of the protective cover 25 and the protective shell 21, so that the sealing rubber ball 46 comes into contact with the outer wall of the protective shell 21 and the protective cover 25, and then a gap is generated between the connecting groove 45 and the conducting groove 44, and then the care oil in the conducting groove 44 leaks to the surface of the protective shell 21 and the protective cover 25, and the surface of the protective shell 21 and the protective cover 25 is lubricated and cared for, thereby preventing the surface of the protective shell 21 and the protective cover 25 from aging and cracking.

[0041] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
