Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing, and in particular to a manufacturing device for a fireproof photovoltaic cable core for a photovoltaic power station and a fireproof photovoltaic cable. Background Art

[0002] Cable is an important material used for power transmission and information transfer. Fireproof photovoltaic cables are fireproof cables that have added fireproof properties to ordinary photovoltaic cables, which allows them to maintain normal operation for a certain period of time when a fire occurs and will not easily burn or spread flames, thereby improving fire resistance and allowing the cables to work at high temperatures. The manufacture of cables is usually a complex process involving multiple steps to ensure the quality and performance of the final product.

[0003] In the existing patent CN104821195A, it includes a cable core and a sheath. The cable core is formed by twisting a number of insulating wire cores. The insulating wire core is composed of a conductor and a fireproof insulating layer. It is characterized in that the fireproof insulating layer is a composite double-layer insulation structure. A polymer composite ceramic polyolefin material is extruded outside the cable core as a fireproof protective layer, and the sheath is placed outside the fireproof protective layer. The constituent materials of the present invention are all halogen-free and environmentally friendly materials, which are pollution-free to the environment and meet the needs of modern people for environmental awareness. The new material "polymer composite ceramic polyolefin" is used as the fireproof layer of the cable. Under the condition of ensuring that the cable has the same fireproof properties, the outer diameter of the cable, the manufacturing cost and the production cycle are reduced, and the production efficiency is improved. At the same time, the fireproof layer structure can form a hard shell after high-temperature combustion, which can protect the line from stress damage, so that the cable can still have the ability to work normally for a long time under the action of the flame.

[0004] In the above structure, the cable can achieve a fire-proof function, but during the cable core twisting process, that is, when the conductor is generated, the cable core needs to be rotationally twisted. When the speed is too fast, the cable core will be forced to produce centrifugal force, thereby causing the cable core to bend, and the automatic correction effect of the cable core cannot be achieved.

[0049] Working principle: When preparing the cable, first use all the conductor monofilaments to twist to form a conductor, then the traction machine continuously pulls out the conductor, pulls the conductor to different extruders, and introduces different required materials to form a fireproof photovoltaic cable in turn;

[0050] Before twisting to form the conductor, preparatory work is performed. The pay-off reel 502 with the secondary conductor monofilament installed is passed through the clamping rod 501 until the pay-off reel 502 is aligned with the clamping rod 501, and the clamping nut 504 is rotated so that the clamping nut 504 is rotated to a reasonable position on the clamping screw 503, so that the clamping nut 504 installs the pay-off reel 502 on the clamping rod 501, so that the pay-off reel 502 and the clamping rod 501 are integrated, and the installation of multiple pay-off reels 502 is completed in sequence according to the steps, and the head of the secondary conductor monofilament on the pay-off reel 502 is pulled out and passed through the guide ring 803, the guide support ring 804, the two adjustment rollers 1005, the wire hole 7, the upper guide roller 902 and the lower guide roller 903 in sequence, until the multiple secondary conductor monofilaments and the main conductor monofilaments are introduced into the bushing 1303 of the paralleling mold 1302, so that the formed conductor passes through the paralleling port 1304 and is wound on the traction machine;

[0051] When the secondary conductor monofilament is twisted with the main conductor monofilament, the motor 401 is started, the output shaft of the motor 401 rotates to drive the driving gear 402 to rotate, the driving gear 402 drives the driven gear 404 to rotate, the driven gear 404 drives the rotating disk 403 to rotate, the rotating disk 403 drives the connecting cylinder 801 and the clamping rod 501 to rotate, the connecting cylinder 801 drives the support rod 802, the guide ring 803 and the guide support ring 804 to rotate synchronously, forcing the secondary conductor monofilament to move synchronously with the guide ring 803 and the guide support ring 804, the connecting cylinder 801 drives the rotating guide plate 6 to rotate synchronously, the rotating guide plate 6 drives the wire hole 7 to move, forcing the sliding block 901, the upper guide roller 902 and the lower guide roller 903 to rotate synchronously, forcing the secondary conductor monofilament to come out of the corresponding wire hole 7, and the main conductor monofilament is led out of the connecting cylinder 801, forcing a plurality of secondary conductor monofilaments to be wound around the main conductor monofilament to form a twist, and at the same time the traction machine pulls out the conductor, so that the formed conductor is continuously pulled out and introduced into the next processing step;

[0052] When the rotation speed is too fast, the secondary conductor monofilament will be centrifugally bent, which will cause the secondary conductor monofilament to derail easily or even wear and break. At this time, the secondary conductor monofilament bends and moves outward. Since the adjusting roller 1005 is in contact with the secondary conductor monofilament, the adjusting roller 1005 is forced to generate a force, so that the adjusting roller 1005 moves clockwise outward. The adjusting roller 1005 drives the rotating block 1004 to rotate, and the rotating block 1004 drives the shaft 1003 to rotate clockwise. Since the adjusting outer rod 1006 is hinged on the fixed plate 1001 and the adjusting inner rod 1007 is hinged on the rotating block 1004, the adjusting spring 1008 is forced to be compressed, and the adjusting inner rod 1007 slides in the adjusting outer rod 1006 to a reasonable position, that is, a force balance is formed under the action of the secondary conductor monofilament and the reverse action of the adjusting spring 1008.

[0053] The shaft 1003 rotates clockwise to drive the transmission gear 1 1101 to rotate, forcing the transmission gear 2 1104 to rotate counterclockwise, and the other transmission gear 1 1101 rotates clockwise. The rotation of the other transmission gear 1 1101 drives another shaft 1003 to rotate clockwise, driving another rotating block 1004 to rotate clockwise, forcing another adjusting roller 1005 to rotate clockwise, so that the other adjusting roller 1005 drives the secondary conductor monofilament to move inward;

[0054] The transmission gear 1104 rotates counterclockwise to drive the rotating rod 1103 to rotate counterclockwise, and the rotating rod 1103 drives the pulley 1202 to rotate counterclockwise. Under the action of the belt 1203, the other pulley 1202 is forced to rotate counterclockwise, and the rotating gear 1204 is forced to rotate counterclockwise, and the spur rack 1206 is forced to move outward. The spur rack 1206 drives the connecting rod 1205 to move, and the connecting rod 1205 drives the sliding block 901 to move outward, forcing the upper guide roller 902 and the lower guide roller 903 to drive the secondary conductor monofilament to move outward. At this time, the length of the secondary conductor monofilament in this section from the guide support ring 804 to the wire hole 7 is increased, thereby reducing the degree of outward bending of the secondary conductor monofilament at the eccentric position. At the same time, because another adjusting roller 1005 drives the secondary The conductor monofilament moves inward, and the upper guide roller 902 and the lower guide roller 903 drive the secondary conductor monofilament to move outward, so that the secondary conductor monofilament is bent inward before entering the wire hole 7 and the guide support ring 804, avoiding the contact between the secondary conductor monofilament and the guide support ring 804 and the rotating guide plate 6, reducing the wear of the secondary conductor monofilament, and finally forcing the secondary conductor monofilament to bend outward to form an S-shaped bend, thereby reducing the degree of bending at the centrifugal position and achieving the effect of automatic correction of the secondary conductor monofilament. When the staff finds it, they slowly reduce the rotation speed until the secondary conductor monofilament is horizontal. At this time, the adjustment component 10, the transmission component 11 and the guide component 9 automatically return to their original positions, thereby completing the automatic adjustment of the secondary conductor monofilament while continuously forming the conductor.
