AI Technical Summary
During the photovoltaic construction process, due to the influence of moisture in the working environment or other factors, moisture will adhere to the surface of the optical cable. When the optical cable is wound into a winding, the moisture is difficult to evaporate, and it is easy to invade the optical cable and react with the optical fiber, causing the optical fiber to attenuate. In the severe cold season, icy and expansion will also damage the optical fiber.
An optical cable winding device for photovoltaic construction is designed, including a water absorption mechanism and a limiting assembly. The water absorption mechanism absorbs moisture on the surface of the optical cable through the cooperation of the sponge water absorption ring and the movable rod, and collects the aqueous solution through the water collection box. The limiting assembly passes through the shaft and gear system to avoid excessive bending of the optical cable during the water absorption process.
It effectively reduces the probability of moisture entering the optical cable, avoids damage to the optical fiber, and maintains the long-term working efficiency of the water absorption mechanism by regularly extruding the sponge water absorption ring. At the same time, the equipment ensures uniform arrangement of optical cables and winding effect through the design of guide rings and winding mechanisms.

Description
Technical Field
[0001] The present invention relates to the technical field of photovoltaic construction, and particularly relates to an optical cable winding device for photovoltaic construction. Background Technique
[0002] Photovoltaic construction is based on the photovoltaic effect, using solar cells to directly convert solar energy into electrical energy. Whether used independently or for grid-connected power generation, a photovoltaic power generation system mainly consists of three major parts: solar panels (modules), a controller, and an inverter. They are mainly composed of electronic components. During the process of photovoltaic construction, it is necessary to bundle the optical cable into several uniform lengths for subsequent use.
[0003] The outermost layer of the optical cable is a plastic sheath, inside which is a metal sheath, and further inside is a water-swellable water-blocking layer. The cable core has an ointment and optical fibers adhered together. Such a setting makes the optical cable have a certain waterproof performance. For the convenience of transportation, currently, a winding device is used to wind the optical cable. However, in actual work, due to the influence of a humid working environment or other factors, a certain amount of moisture will adhere to the surface of the optical cable. When the optical cable is wound into a roll, the moisture is even more difficult to volatilize, resulting in the moisture being easily introduced into the interior of the optical cable and reacting chemically with the optical fibers, causing an increase in optical fiber attenuation. In severe cold seasons, ice expansion will also damage the optical fibers. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENT
[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1 to 4 As shown in the figure, the present invention is an optical cable winding device for photovoltaic construction, including a base 1. Support plates 11 are symmetrically arranged on the base 1. A winding mechanism is arranged between the two support plates 11. A movable column 2 is arranged on the base 1. A guiding ring 3 is fixed at the top of the column 2. A water absorption mechanism 4 is fixed on one side of the column 2. The water absorption mechanism 4 includes two moving plates 401. A water collecting box 402 is jointly fixed at the bottom of the two moving plates 401. The cross-section of the water collecting box 402 is an isosceles trapezoid structure with a wider top and a narrower bottom. One side of the water collecting box 402 is fixedly connected to the column 2 through a fixing rod 418. Activity rods 403 are movably arranged on both of the two moving plates 401. Extrusion blocks 405 are arranged at the closer ends of the two activity rods 403. A sponge water absorption ring 406 is arranged on the closer side of the two extrusion blocks 405. Force-bearing blocks 404 are fixed at the farther ends of the two activity rods 403. A first spring 407 is connected between the force-bearing block 404 and the moving plate 401. L-shaped push rods 5 are fixed on the outer side walls of the two support plates 11 away from each other. The push rods 5 are at the same height as the force-bearing blocks 404. Limit components are arranged on both of the two moving plates 401 to make the bending angle of the optical cable small when the sponge water absorption ring 406 is extruded. When winding the optical cable, the optical cable is sequentially passed through the guiding ring 3 and the sponge water absorption ring 406 and then fixed on the winding mechanism. The winding mechanism works to wind the cable. At the same time, the column 2 drives the guiding ring 3 and the water absorption mechanism 4 to move. The movement of the guiding ring 3 makes the optical cable arranged evenly. The sponge water absorption ring 406 wipes and dries the water on the surface of the optical cable. When the water absorption mechanism 4 moves from one end to the other end, the push rod 5 will push the force-bearing block 404 to move. After the force-bearing block 404 moves, it extrudes the sponge water absorption ring 406, thereby discharging the water. The aqueous solution drips into the water collecting box 402 for collection. When the water absorption mechanism 4 moves back towards the initial position again, under the action of the first spring 407, the force-bearing block 404 resets. When it moves to the initial position, it squeezes the sponge water absorption ring 406 again. This process is continuously repeated, so that no water remains on the surface of the optical cable after winding, reducing the probability of water invading the interior of the optical cable.
[0020] Refer to Figure 1 、 Figure 3 and Figure 4, the limiting component includes a mounting rod 408 fixed to one side of the moving plate 401. A rotating shaft 409 is rotatably mounted on the mounting rod 408. A limiting plate 410 is mounted on the rotating shaft 409. A gear 411 is mounted at one end of the rotating shaft 409. Rack bars 6 are mounted on the side walls of the two support plates 11 close to each other. The rack bars 6 are meshed with the gear 411. In order to avoid large bending of the optical cable during extrusion, the limiting component is used to limit the force-receiving block 404. When the water absorption mechanism 4 moves to one side, the gear 411 on this side contacts and meshes with the rack bar 6, causing the limiting plate 410 to flip by 90°. The limiting plate 410 on this side releases the limit on the force-receiving block 404, and the force-receiving block 404 can be pushed by the push rod 5. While the limiting plate 410 on the other side blocks the force-receiving block 404 on the other side to prevent it from moving, so that large bending of the optical cable can be avoided during extrusion.
[0021] Refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 , cross plates 413 are fixed on both side walls of the water collecting box 402. A lifting rod 414 is movably arranged on the cross plate 413. A U-shaped positioning frame 416 is fixed at one end of the lifting rod 414, and a collar 415 is fixed at the other end. A second spring 417 is connected between the positioning frame 416 and the cross plate 413. A positioning block 412 is arranged at the end of the limiting plate 410 close to the rotating shaft 409, and the positioning block 412 matches the positioning frame 416 in size. Guide rods 7 are fixed on the side walls of the two support plates 11 away from each other. The guide rod 7 is composed of two straight line segments and an inclined line segment, and the inclined line segment is located between the two straight line segments. In order to prevent the limiting plate 410 on the other side from flipping during extrusion, the positioning block 412 on the limiting plate 410 is fixed by the positioning frame 416, so that the limiting plate 410 on the other side cannot flip during extrusion, ensuring the extrusion drainage effect.
[0022] Refer to Figure 1 and Figure 7 , the winding mechanism includes a winding roller rotatably mounted between the two support plates 11. A winding motor is mounted on one of the support plates 11, and the output shaft of the winding motor is connected to the winding roller. A drying plate 10 is mounted between the two support plates 11. The drying plate 10 is of a cavity structure, and ventilation holes are arrayed on one side wall of the drying plate 10. An air inlet pipe is connected to the drying plate 10, and one end of the air inlet pipe is connected to an external air source, and the external air source is a hot air blower. A track 8 is arranged on the base 1. A slider 9 is slidably connected in the track 8, and the slider 9 is fixed to the column 2. A reciprocating lead screw is arranged in the track 8, and the reciprocating lead screw is threadedly connected to the slider 9. A driving motor is mounted on one side of the track 8, and the output shaft of the driving motor is connected to the reciprocating lead screw.
[0023] Working principle of the present invention: During winding, the optical cable is sequentially passed through the guiding ring 3 and the sponge water-absorbing ring 406 and then fixed on the winding roller. The winding motor (not shown) is started to drive the winding roller to rotate for winding. At the same time, the driving motor (not shown) is started to drive the reciprocating lead screw (not shown) to rotate, so that the slider 9 and the column 2 move along the track 8. The column 2 drives the guiding ring 3 and the water-absorbing mechanism 4 to move. The movement of the guiding ring 3 arranges the optical cable evenly, and the sponge water-absorbing ring 406 wipes and dries the moisture on the surface of the optical cable; Take Figure 1 as an example. When the water-absorbing mechanism 4 moves from the left side to the right side, the left gear 411 contacts and meshes with the left rack 6, causing the left limiting plate 410 to rotate clockwise by 90°. And the left collar 415 moves along the left guiding rod 7. When the collar 415 moves to the inclined section of the guiding rod 7, the collar 415 and the lifting rod 414 gradually rise, so that the positioning frame 416 cooperates with the positioning block 412 to fix the position of the left limiting plate 410. When the water-absorbing mechanism 4 is about to move to the right side, the right collar 415 cooperates with the guiding rod 7, the collar 415 and the lifting rod 414 descend, and the right positioning frame 416 disengages from the positioning block 412 to release the positioning of the right limiting plate 410. Subsequently, the right gear 411 contacts and meshes with the rack 6, causing the right limiting plate 410 to rotate clockwise by 90°. Finally, the force-receiving block 404 contacts the push rod 5, and the push rod 5 will push the force-receiving block 404 to move. After the force-receiving block 404 moves, it drives the extrusion block 405 to extrude the sponge water-absorbing ring 406, thereby discharging the moisture. The aqueous solution drips into the water collection box 402 for collection. At this time, the left force-receiving block 404 and the extrusion block 405 are blocked by the left limiting plate 410 and cannot move, avoiding the optical cable from being squeezed and bent. Similarly, when the water-absorbing mechanism 4 moves to the rightmost end and then moves to the left side again, the right limiting plate 410 is reset. Before extrusion, the left limiting plate 410 will rotate counterclockwise by 90° to a horizontal state, and then the extrusion and drainage work is carried out again. This process is continuously repeated, so that no moisture remains on the surface of the optical cable after winding, reducing the probability of moisture invading the inside of the optical cable and ensuring the winding effect; After the optical cable is wound on the winding roller, a hot air blower (not shown) is used to convey hot air into the drying plate 10, and then it is blown onto the optical cable through the ventilation holes to further improve the drying effect.
[0024] The above has described an embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
