Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to an interlocking armored directly buried photovoltaic cable processing device and a processing method. Background Art

[0002] With the rapid development of solar photovoltaic technology, photovoltaic cables, as an indispensable part of the photovoltaic system, their performance and quality are directly related to the operating efficiency and safety of the entire photovoltaic system. The interlocking armored directly buried photovoltaic cable is applied to direct burial laying, and has excellent mechanical protection performance and corrosion resistance. During its processing, it is necessary to perform water cooling and shaping on the extruded cable.

[0003] For this reason, Chinese Patent No. CN118507164A proposes a cable processing device and a cable processing method that can initially cool the cable through the chuck part to avoid deformation during subsequent cooling and affect the performance. However, when this device is used, the insulating layer of the extruded cable is in a high-temperature state and is easily oxidized when exposed to air, resulting in material degradation, rough surface or reduced electrical performance. At the same time, its nozzle can only reciprocate linearly under the drive of the slide plate, resulting in the spraying of the water spray trajectory in a single plane and unable to form a circumferential continuous coverage, easily resulting in cooling blind spots, inconvenient to use, and requiring an additional power source such as a water pump to transport cold water, with low automation.

One ends of the plurality of first connecting pipes 11 are respectively communicated with the plurality of water boxes 10.

[0032] A processing method for the above interlocking armored directly buried photovoltaic cable processing device includes the following steps:

[0033] First step, make the cable core formed by stranding the conductors sequentially pass through the push head 31, the extrusion pipe 3, the rotating pipe 8 and the water pipe 12;

[0034] Second step, start the servo motor 5 to make its output shaft rotate intermittently clockwise and counterclockwise. Make the cable move forward through the driving component so that its exterior is wrapped with an insulating layer. By setting the anti-oxidation component, blow argon gas to the extruded cable to inhibit the oxidation of the insulating layer, reducing surface defects. By setting the water cooling component, perform spiral water spraying on the outer circumference of the cable for preliminary cooling and shaping.

[0035] When the present invention is in use, the cable core formed by stranding wires sequentially passes through the push head 31, the extrusion pipe 3, the rotating pipe 8 and the water pipe 12. After the cable core passes through the extrusion pipe 3, an insulating layer is wrapped around the outside. The insulating layer is generally made of rubber, and the melted rubber is wrapped around the cable core. The servo motor 5 is started to make its output shaft rotate reciprocally clockwise and counterclockwise. By setting the rotating shaft 21 and the first bevel gear 20, the second bevel gear 22 can be made to rotate reciprocally clockwise and counterclockwise, and then the rotating pipe 8 can be made to rotate reciprocally clockwise and counterclockwise. By setting the spiral moving groove 9, the moving block 30 and the guiding of the two air outlet rods 29 on the moving orifice plate 6, the moving orifice plate 6 can be made to move reciprocally back and forth. When the moving orifice plate 6 moves reciprocally back and forth, by setting the long plate 19, the moving box 2 and the push plate 4 can be made to move reciprocally back and forth. When the moving box 2 and the push plate 4 move forward, the sliding pipe 32 is driven to move forward, so that the sliding pipe 32 moves relative to the elastic clamping plate. The inner diameter of the inner wall of the sliding pipe 32 gradually decreases, so that the elastic clamping plate can be squeezed during movement, and the front end of the elastic clamping plate can be clamped inwardly on the cable core. Then, as the sliding pipe 32 continues to move, the compression return spring is compressed, and then the push head 31 is driven to move synchronously, so as to clamp the cable core and move forward synchronously. At the same time, by setting the slideway, the elastic rod 35, the first inclined surface and the second inclined surface, the two clamping heads 33 can be made to approach each other to wrap the cable, avoiding knocking the insulating layer and causing deformation. When the moving box 2 and the push plate 4 move backward, the sliding pipe 32 is reset, and the cable is no longer clamped by the front end of the elastic clamping plate. At the same time, the two clamping heads 33 move away from each other and reset;

[0036] When the moving orifice plate 6 moves reciprocally back and forth, by setting the air outlet rod 29, the air outlet piston 28 can be made to slide reciprocally back and forth in the air blowing cylinder 16, so that the argon gas in the air storage box 15 can be reciprocally sucked into the air blowing cylinder 16 through the air inlet pipe 18 and then be squeezed and sprayed onto the extruded cable through the air outlet pipe 17, so as to inhibit the oxidation of the insulating layer and reduce surface defects. When the moving orifice plate 6 moves reciprocally back and forth, by setting the connecting rod 7, the rectangular plate 23 and the water pipe 12 can be made to move reciprocally back and forth. When the rotating pipe 8 rotates reciprocally clockwise and counterclockwise, by setting the mounting block 24 and the water outlet rod 26, the water pipe 12 can be made to rotate reciprocally clockwise and counterclockwise accordingly. In this way, the water pipe 12 can rotate reciprocally clockwise and counterclockwise while moving reciprocally back and forth, so that the water outlet piston 27 can reciprocally slide back and forth in the cavity 25. The water in the water box 10 is sucked into the cavity 25 through the first connecting pipe 11 and then is squeezed and sprayed out through the second connecting pipe 13. Repeating this way, the cable can be spirally sprayed with water for preliminary cooling and shaping, improving the cooling and shaping effect.

[0037] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
