Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic construction, and specifically 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 components: 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-blocking layer that swells when exposed to water. The cable core has an ointment and optical fibers glued together. This setting gives the optical cable a certain degree of waterproof performance. For convenient 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 coil, the moisture is even more difficult to volatilize, resulting in the moisture easily penetrating into the interior of the optical cable and reacting 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

[0004] The purpose of the present invention is to provide an optical cable winding device for photovoltaic construction, and solve the following technical problems: 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 coil, the moisture is even more difficult to volatilize, resulting in the moisture easily penetrating into the interior of the optical cable and reacting with the optical fibers, causing an increase in optical fiber attenuation. In severe cold seasons, ice expansion will also damage the optical fibers.

L-shaped push rods are fixedly arranged on the farther side walls of the two support plates. The push rods are at the same height as the force receiving blocks;

[0008] Limit components are arranged on the two moving plates, so that the bending angle of the optical cable is small when the sponge water absorption ring is extruded.

[0011] As a further scheme of the present invention: cross plates are fixedly arranged on the two side walls of the water collecting box. A lifting rod is movably arranged on the cross plate. A U-shaped positioning frame is fixedly arranged at one end of the lifting rod, and a sleeve ring is fixedly arranged at the other end.

A positioning block is arranged at the end of the limit plate close to the rotating shaft, and the positioning block is matched with the positioning frame in size. Guide rods are fixedly arranged on the farther side walls of the two support plates.

[0012] As a further scheme of the present invention: the guide rod is composed of two straight line segments and an oblique line segment, and the oblique line segment is located between the two straight line segments.

[0016] Advantages of the present invention:

[0017] (1) By setting the water absorption mechanism, when winding the optical cable, the water on the surface of the optical cable can be wiped and dried, thereby greatly reducing the probability of water intrusion into the optical cable, avoiding damage to the internal optical fiber, and the sponge water absorption ring can be squeezed regularly to squeeze out the water in the sponge water absorption ring, which is beneficial to the long-term operation of the water absorption mechanism. Moreover, the water absorption mechanism can move together with the guiding ring, enabling the optical cable to be evenly arranged on the winding mechanism and improving the winding effect;

[0018] (2) By setting the limiting component, in order to avoid bending the optical cable when squeezing the sponge water absorption ring, the limiting plate in the limiting component flips according to the position, thereby supporting one side of the optical cable, having little influence on the optical cable when squeezing the sponge water absorption ring, avoiding deformation of the optical cable, and ensuring the winding effect;

[0019] (3) By setting structures such as the lifting rod, the sleeve ring, the positioning frame, and the positioning block, the positioning block is fixed by the positioning frame, thereby fixing the position of the limiting plate, avoiding the flipping of the limiting plate when stressed, and ensuring the squeezing effect.

Detailed implementation manners

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 4As shown in the figure, the present invention is an optical cable winding device for photovoltaic construction, including a base 1. On the base 1, support plates 11 are symmetrically arranged. Between the two support plates 11, a winding mechanism is provided. On the base 1, a movable column 2 is provided. At the top of the column 2, a guide ring 3 is fixed. On one side of the column 2, a water absorption mechanism 4 is fixed; the water absorption mechanism 4 includes two moving plates 401. At the bottom of the two moving plates 401, a water collection box 402 is jointly fixed. The cross-section of the water collection box 402 is an isosceles trapezoid structure with a wider top and a narrower bottom. One side of the water collection box 402 is fixedly connected to the column 2 through a fixing rod 418. On both moving plates 401, movable rods 403 are movably arranged. At the closer ends of the two movable rods 403, extrusion blocks 405 are provided. On the closer sides of the two extrusion blocks 405, a sponge water absorption ring 406 is provided. At the farther ends of the two movable rods 403, force-receiving blocks 404 are fixedly connected. Between the force-receiving blocks 404 and the moving plates 401, first springs 407 are connected. On the farther side walls of the two support plates 11, L-shaped push rods 5 are fixedly connected. The push rods 5 are at the same height as the force-receiving blocks 404; on both moving plates 401, limiting components are provided to make the bending angle of the optical cable small when the sponge water absorption ring 406 is extruded; when winding the cable, the optical cable is sequentially passed through the guide 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 guide ring 3 and the water absorption mechanism 4 to move. The movement of the guide 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-receiving block 404 to move. After the force-receiving block 404 moves, it extrudes the sponge water absorption ring 406, thereby discharging the water. The aqueous solution drips into the water collection 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-receiving block 404 resets. When it moves to the initial position, it extrudes 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 inside of the optical cable.

[0032] 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 engaged with the gear 411. To prevent the optical cable from being bent too much during extrusion and affecting the winding, 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 that side contacts and engages with the rack bar 6, causing the limiting plate 410 to flip 90°. The limiting plate 410 on that side releases the limit on the force-receiving block 404, and the force-receiving block 404 can then be pushed by the push rod 5. The limiting plate 410 on the other side blocks the force-receiving block 404 on the other side and prevents it from moving. In this way, the optical cable can be prevented from being bent too much during extrusion.

[0033] 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. Lifting rods 414 are movably arranged on the cross plates 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. 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. In this way, the limiting plate 410 on the other side cannot flip during extrusion, ensuring the extrusion and drainage effect.

[0034] 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 has 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. 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.

[0035] 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 absorbs the moisture on the surface of the optical cable;

[0036] 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 squeeze 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 to ensure 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;

[0037] 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.

[0038] The above has described an embodiment of the present invention in detail, but the content described is only the 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 shall still fall within the scope covered by the patent of the present invention.
