Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a flexible, high-performance aluminum alloy photovoltaic cable manufacturing system and the cable thereof. Background Technology

[0002] Photovoltaic cables are specialized cables for solar power generation systems. The core difference lies in their material properties and environmental adaptability. They use special irradiated cross-linked materials that can resist ultraviolet rays, high temperatures, and mechanical damage for a long time, while ordinary cables cannot meet the requirements of extreme outdoor environments. Photovoltaic cables need to be matched with the DC voltage characteristics of the solar system. Ordinary cables may cause short circuits or reduced efficiency due to insufficient insulation. During the cable manufacturing process, an insulation layer needs to be wrapped around the outside of the conductor using a cable extruder to ensure its normal use and safety.

[0003] The patent application number CN202420902132.2 mentions "a cable extruder that is easy to heat". This equipment reduces heat loss by setting an insulation layer, makes it easier to adjust the temperature inside the mixing drum, and improves the heating effect of the material by setting an opposing conical structure of the mixing rod and mixing drum, thereby improving the stability of the extruded material.

[0004] However, in the current cable manufacturing process, the conductor wire needs to pass exactly through the center of the cable extruder. If there is a deviation, it will lead to uneven insulation thickness or even wear on the mold. After the cable is wrapped with insulation, its outer side is a softened insulation layer. When it is transported to the cooling structure, the outer side tends to gather downwards due to gravity. When it is directly fed into the cooling structure, the outer side is prone to unevenness due to excessive temperature difference and uneven cooling. Summary of the Invention

[0005] This invention provides a flexible, high-performance aluminum alloy photovoltaic cable manufacturing system and cable, which can effectively solve the problems mentioned in the background art, such as misalignment, uneven cable insulation layer thickness, even wear on the mold, tendency of the outer side to tend to gather downward due to gravity, and unevenness of the outer side of the cable due to excessive temperature difference and uneven cooling when directly fed into the cooling structure.

[0017] According to the above technical solution, a high-efficiency cooling component is installed on one side of the counterweight water tank, and the high-efficiency cooling component includes a high-efficiency water-cooled box;

[0018] A high-efficiency water-cooled box is placed on one side of the counterweight water tank. A liquid nitrogen pump is installed at the bottom of the outer side of the high-efficiency water-cooled box. The discharge end of the liquid nitrogen pump passes through the high-efficiency water-cooled box and is connected to a liquid nitrogen box.

[0020] According to the above technical solution, a high-efficiency water-cooled box is placed on one side of the counterweight water tank.

[0022] According to the above technical solution, the inner tube, extrusion head, support box and high-efficiency water-cooled box pass through the cable in sequence;

[0023] A wire diameter measuring instrument is placed between the outlet pipe and the extended external threaded pipe.

[0024] The input terminals of the tensioning electric actuator, liquid nitrogen pump, exhaust fan, and wire diameter gauge are electrically connected to the output terminal of the external controller.

[0025] A flexible, high-performance aluminum alloy photovoltaic cable, manufactured by a flexible, high-performance aluminum alloy photovoltaic cable manufacturing system according to the above technical solution, wherein the cable contains an aluminum alloy conductor.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. Equipped with a cooling guide assembly, the aluminum alloy conductor is wrapped with an insulation layer through an extrusion head to form a cable. The contact point between the cable and the two inner hollow rollers is cooled while preventing the outer insulation layer from directly contacting and sticking to the inner hollow rollers.

[0028] The negative pressure at both ends of the exhaust pipe near the atomizing tube will attract water mist to be discharged through the exhaust pipe. During this process, the water mist will come into contact with the high-temperature outer insulation layer and cool it. In conjunction with the aforementioned hollow inner roller, the outer side of the cable can be quickly and initially cooled and supported. While initially hardening, it prevents deformation of the outer insulation layer, thereby reducing the temperature difference during subsequent cooling of the cable, resulting in better cooling effect and avoiding unevenness and bumps on the outer side.

[0029] 2. A centering adjustment component is provided. When the aluminum alloy conductor enters the extrusion head, the slider will slide along the spring groove under the push of the reset spring in the spring groove. The centering wheel is close to the aluminum alloy conductor. If the pressure difference between the aluminum alloy conductor and each micro pressure sensor is very small, the aluminum alloy conductor will be in the center position, and the insulation layer can be directly extruded and wrapped.

[0030] If the pressure difference between the various miniature pressure sensors is large, the drive gear will rotate the gear ring, which in turn will rotate the outer tube inside the mounting ring. This will cause the center wheel to rotate and push the aluminum alloy conductor closer to the center position. During this process, the ball rolls on the outside of the aluminum alloy conductor to prevent scratching the cable, improve the centering rate of the internal conductor, and improve the forming effect.

[0031] If the pressure difference between the various miniature pressure sensors is large and cannot be adjusted by the above methods, manual inspection is required. Different solutions should be used for different deviations to ensure that the aluminum alloy conductor is centered inside the cable and to prevent the mold from being scratched.

[0032] 3. Equipped with a high-efficiency cooling component, after the initial cooling is completed, the cable enters the high-efficiency water cooling box through the internal threaded pipe. The cable will be cooled by the cooling water. The liquid nitrogen pump slowly delivers liquid nitrogen and discharges it through the liquid nitrogen box and grid holes, cooling the cooling water and the cable at the same time, improving the cooling effect. The return water pipe will draw water from the top to the bottom. The water discharged from the uniform drainage holes at the bottom of the inverted T-shaped pipe will come into contact with the liquid nitrogen and cool it quickly, maintaining the cooling effect.

[0033] The exhaust fan accelerates airflow and evaporation on the outside of the cable outside the movable guide roller, aiding in cooling and improving the cooling effect. This method of cooling not only improves the cooling effect but also reduces the waste of cooling water and the space occupied. If the cable insulation layer is thick, another high-efficiency water-cooled box can be installed side by side on one side of the high-efficiency water-cooled box. The internal threaded pipe connects the two opposite extended external threaded pipes, which can further improve the cooling effect. Depending on the usage requirements, the cooling efficiency is guaranteed, and the use is more convenient.

[0034] In summary, both the guiding cooling component and the centering adjustment component can provide auxiliary support for the cable. The central axis of the inner tube and the axis of the outlet tube coincide, allowing the centering adjustment component to better center the cable. The two components work together to achieve better adjustment. The guiding cooling component provides initial cooling, hardens the outer insulation layer, and reduces the temperature difference of the subsequent high-efficiency cooling component, improving the cooling and shaping effect. This results in a smoother outer surface of the cable after cooling. The three components work together to achieve a better cable shaping effect. Attached Figure Description

[0064] A return water pipe 610 is installed on one side of the high-efficiency water-cooled box 601. A return water pump 611 is installed in the middle of the return water pipe 610. The bottom end of the return water pipe 610 passes through the bottom end of the high-efficiency water-cooled box 601 and is connected to an inverted T-shaped pipe 612. The inverted T-shaped pipe 612 has uniformly spaced drainage holes 613 near the top surface of the liquid nitrogen box 608. A filter box 614 is connected to the top end of the return water pipe 610. The filter box 614 is connected to the inside of the high-efficiency water-cooled box 601. The middle of the top surface of the high-efficiency water-cooled box 601 is... An exhaust fan 618 is installed through the tube. Two opposite external threaded tubes 602 are respectively connected to the two ends of the internal threaded tube 615 by threads. Anti-deviation tubes 616 are welded on both sides of the external threaded tube 602 on one side of the high-efficiency water-cooled box 601.

The inner tube 408, the extruder 2, the support box 303 and the high-efficiency water-cooled box 601 pass through the cable 7 in sequence.

[0065] A wire diameter gauge 5 is placed between the outlet pipe 304 and the extended external thread pipe 602. The input terminals of the tensioning electric actuator 606, liquid nitrogen pump 607, exhaust fan 618 and wire diameter gauge 5 are electrically connected to the output terminal of the external controller to ensure that the tensioning electric actuator 606, liquid nitrogen pump 607, exhaust fan 618 and wire diameter gauge 5 work normally.

[0066] like Figure 10 As shown, a flexible high-performance aluminum alloy photovoltaic cable is manufactured by a flexible high-performance aluminum alloy photovoltaic cable manufacturing system according to the above technical solution. The cable 7 has an aluminum alloy conductor 8 inside.

[0067] The working principle and usage process of this invention: The aluminum alloy conductor 8 passes through the center position of the inner tube 408, and the height of the telescopic adjustment rod 402 is adjusted so that the axis of the inner tube 408 coincides with the axis of the extrusion head 2 and enters the extrusion head 2. During this process, under the pushing action of the reset spring 412 in the spring groove 411, the slider 414 will slide along the spring groove 411, and the center wheel 416 will approach the aluminum alloy conductor 8 until the outer ball 417 is in contact with the outer side of the aluminum alloy conductor 8.

[0068] During the conveying process, if the pressure difference between the aluminum alloy conductor 8 and each micro pressure sensor 413 is small, the aluminum alloy conductor 8 will be in the center position. If the pressure difference between the micro pressure sensors 413 is large, the centering motor 407 will be started, driving the drive gear 406 to rotate the gear ring 405, which in turn drives the outer tube 404 inside the mounting ring 403 to rotate. This causes the centering wheel 416 to rotate and push the aluminum alloy conductor 8 closer to the center position. During this process, the ball bearing 417 rolls on the outside of the aluminum alloy conductor 8 to prevent scratching the cable 7. If the pressure difference between the micro pressure sensors 413 is large and cannot be adjusted by the above adjustment method, manual inspection is required. Different solutions are used for different deviations to ensure that the aluminum alloy conductor 8 is in the center position inside the cable 7 and to prevent the mold from being scratched.

[0069] Next, the aluminum alloy conductor 8 is wrapped with an insulating layer through the extrusion head 2 to form a cable 7. At this time, the outer side of the cable 7 will immediately enter the space between the two inner hollow rollers 310 of the support box 303 through the outlet pipe 304. The cooling fan 316 is started. The air supplied by the cooling fan 316 enters the inner hollow roller 310 through the docking box 315, the air supply ring 313 and the air supply hole 314 in sequence. Finally, it is sprayed out from the cooling air hole 317 to the outer side of the cable 7 between the two inner hollow rollers 310. While cooling the contact position between the cable 7 and the two inner hollow rollers 310, the outer insulating layer and the inner hollow rollers 310 are prevented from directly contacting and sticking together.

[0070] When the ultrasonic atomizer 306 is activated, the water in the counterweight water tank 301 is atomized. The mist enters the atomizing tube 305 through the telescopic tube 302 and is discharged from both ends of the atomizing tube 305. When the exhaust air pump 309 is activated, the two ends of the exhaust pipe 307 near the end of the atomizing tube 305 are under negative pressure, which will attract water mist to be discharged through the exhaust pipe 307. During this process, the water mist will come into contact with the high-temperature outer insulation layer and cool the outer insulation layer. In conjunction with the aforementioned hollow inner roller 310, the outer side of the cable 7 can be quickly and initially cooled and supported. While initially hardening, the deformation of the outer insulation layer is avoided, which reduces the temperature difference when the cable 7 is cooled later, resulting in better cooling effect and avoiding unevenness and bumps on the outer side.

[0071] Both the cooling guide assembly 3 and the centering adjustment assembly 4 can provide auxiliary support for the cable 7. The central axis of the inner tube 408 and the axis of the outlet tube 304 coincide, which makes the centering adjustment assembly 4 better able to center the cable 7. The two components work together to achieve better adjustment.

[0072] After initial cooling, the wire diameter gauge 5 measures the outer diameter of the cable 7. Cooling water is poured into the high-efficiency water-cooling box 601, with the water level equal to the top of the return water pipe 610. The cable 7 enters the high-efficiency water-cooling box 601 through the internal threaded pipe 615. During the cooling process, the cable 7 is first guided by two fixed guide rollers 603 on one side and then passes around the movable guide roller 605 at the top. It is then guided by two fixed guide rollers 603 on the other side and then led out from the internal threaded pipe 615. The tensioning electric push rod 606 is activated to push the movable guide roller 605 along the guide opening 604 to prevent over-tensioning and deformation of the insulation layer on the outside of the cable 7 that has not been fully cooled. During the movement of the cable 7, the cable 7 will be cooled by the cooling water.

[0073] During the cooling process described above, as the water temperature rises, the liquid nitrogen pump 607 is activated, slowly introducing liquid nitrogen and discharging it through the liquid nitrogen box 608 and the grid holes 609. This simultaneously cools the cooling water and the cable 7, improving the cooling effect. Meanwhile, the water is pumped by the return water pump 611, and the return water pipe 610 draws water from the top to the bottom. The water discharged from the uniform drainage holes 613 at the bottom of the inverted T-shaped pipe 612 comes into contact with the liquid nitrogen, rapidly cooling it and maintaining the cooling effect. The exhaust fan 618 continues to run, accelerating airflow and evaporation on the outside of the cable 7 outside the movable guide roller 605, thus assisting in cooling. Cooling improves the cooling effect, reduces the waste of cooling water, and reduces the space occupied. If the insulation layer of cable 7 is thick, a single high-efficiency water-cooled box 601 cannot completely cool it. In this case, another high-efficiency water-cooled box 601 is installed side by side on one side of the high-efficiency water-cooled box 601. The anti-deviation pipe 616 is aligned with the anti-deviation rod 617 and the internal threaded pipe 615 connects the two opposite extended external threaded pipes 602, which can further improve the cooling effect. Depending on the needs of use, the cooling efficiency is guaranteed and the use is more convenient.

[0074] The cooling component 3 guides the initial cooling, hardens the outer insulation layer, and reduces the temperature difference of the subsequent high-efficiency cooling component 6, improving the cooling and forming effect. This makes the outer side of the cable 7 smoother after cooling. The two components work together to achieve a better cooling effect.

[0075] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
