Description

Technical Field

[0001] The utility model relates to the field of cable storage, in particular to a cable storage device for photovoltaic engineering cables. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They transmit electricity or information from one place to another. Each group of conductors is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. Cables have the characteristics of being powered inside and insulated outside.

[0003] After searching, the existing Chinese patent announcement number is: CN220484949U, which provides a cable storage device for photovoltaic engineering cables. The patent provides a number of connecting components on both sides of the support rod, and a limit component is provided at the end of the connecting component away from the support rod. In this way, when the storage tray is inserted into the connecting component, the limit component flips over and contacts the storage tray. The limit component and the storage tray are connected to each other, which avoids the rotation of the storage tray and avoids the problem of internal cables falling off due to the rotation of the storage tray.

[0004] Although the above patent can fix the cable to prevent it from falling off, there are still the following problems in actual use: when the cable is rolled up and stored, some dust will be absorbed on the surface of the cable. If the dust is not cleaned in time, the insulation layer will be contaminated, affecting the insulation performance of the cable, thereby causing safety problems such as cable leakage. At the same time, if it is in a dusty environment for a long time, the insulation layer of the cable will become brittle, aged, and easy to crack, and even insulation breakdown will occur, which has low safety and low practicality.

[0005] In view of the above problems, we propose a cable storage device for photovoltaic engineering cables. Utility Model Content

The right end of the first worm 17 rotates and passes through the connecting box 4. The staff can drive the two first worm gears 16 to rotate synchronously by rotating the first worm 17. The rotation of the two first worm gears 16 drives the two right-side bidirectional threaded rods 8 to rotate respectively, thereby finally realizing the wiping or fixing of the cable.

[0031] Combination Figure 6 The winding assembly includes a winding roller 18, which is rotatably connected to the interior of the storage box 3, and the front end of the winding roller 18 rotates and penetrates into the interior of the storage box 3.

[0033] Combination Figure 1 The upper part of the storage box 3 is rotatably connected with a cover body 22. The setting of the cover body 22 is convenient for the staff to perform the threading operation and also convenient for the staff to take the cable.

[0034] Working principle: when the staff needs to reel up and store the cable, the cable is passed through the interior of the storage box 3 through the first wire hole 5 and the second wire hole 6 and bypasses the reeling component. The staff then operates the driving component to rotate clockwise, which will drive the right-side bidirectional threaded rod 8 to rotate. At this time, the rotation of the right-side bidirectional threaded rod 8 drives the driving gear 14 to rotate, and the rotation of the driving gear 14 drives the driven gear 15 to rotate in the opposite direction, so that the left-side bidirectional threaded rod 8 rotates in the opposite direction. The rotation of the two bidirectional threaded rods 8 will make the two guide plates 9 on the left side approach each other inside the guide groove 7, while the two guide plates 9 on the right side will be in the guide groove 7.

After the subsequent winding and wiping are completed, the driving assembly is operated to rotate counterclockwise again. At this time, the two guide plates 9 on the left will move away from each other, and the two guide plates 9 on the right will move closer to each other, thereby driving the two second connecting plates 11 on the right to move closer to each other, until the two second connecting plates 11 clamp the cable, and the anti-slip pad 13 will contact the cable, and finally the cable is limited and fixed.
