Description

A special storage tool for substation optical fiber

technical field

The utility model relates to a supporting tool for substation construction and maintenance, in particular to a special storage tool for optical fiber in a substation.

Background technique

Workers in the power industry need to carry a large number of optical cables during the construction and maintenance of digital smart substations. When carrying the optical cables, they need to be wound and stored on the reels, but the existing reels cannot fix the joints of the optical cables. The wound optical cable is easily loosened from the reel during transportation, causing the optical fiber connector at the end of the optical cable to drop to the ground. Since the optical fiber connectors are mostly made of fine plastic parts, they are easily damaged when they are squeezed or stepped on , leading to the failure of normal communication of the optical cable, we can only wait for professionals to use optical fiber splicing equipment to remake the optical fiber connector on site, which seriously affects the work progress.

detailed description

A special storage tool for substation optical fiber described in the utility model includes a cylindrical roller, the outer peripheral walls of the two ends of the cylindrical roller are respectively provided with a first baffle 2 and a second baffle 3, the first baffle 2 and the second baffle A plurality of gaps 4 are provided on the circumference of the plate 3, and each gap 4 is evenly distributed along the first baffle 2 or the second baffle 3 circles. The gap 4 on the first baffle 2 and the gap 4 on the second baffle 3 The position corresponds to one by one, the inner wall of the cylindrical roller is provided with a ring guide rail 5, and the first slider 6 is installed on the ring guide rail 5, and the first slider 6 can move along the ring guide rail 5, and the first slider 6 and the first strap 7 end To connect, the front and back sides of the first strapping strap 7 are respectively provided with a hook surface and a suede surface of the Velcro. The cylinder roller described in the utility model and the first baffle plate 2 and the second baffle plate 3 at both ends jointly constitute a reel for accommodating the optical cable. When the optical cable is accommodated, the optical cable is wound on the outer wall of the cylinder roller. The first slider 6 moves along the circular guide rail 5 to the position corresponding to the notch 4 at the end of the optical cable, and uses the first strap 7 on the first slider 6 to pass through the notch 4 to bind the end of the optical cable on the reel, and the Velcro on the strap Prevents strapping from unraveling. The notch 4 can limit the position of the strapping strap and prevent the strapping strap from shifting. The utility model can fix the ends of the accommodated optical cables, prevent the wound optical cables from being scattered, avoid damage to the optical fiber joints at the ends of the optical cables, and at the same time help to improve the convenience of carrying the optical cables.

Because the optical cable itself has a certain hardness, the head end of the optical cable will always move or open when it is directly wound on the reel, which is difficult to operate. In order to fix the head end of the optical cable, the utility model can adopt the following The above structure: the first baffle plate 2 and the second baffle plate 3 have at least one group of gaps 4 at the bottom that are aligned with the outer surface of the cylindrical roller, and the second slider 8 is also installed on the ring guide rail 5, and the second slider 8 is also Can move along the circular guide rail 5, the second slide block 8 is connected with one end of the second binding belt 9, and the front and back sides of the second binding belt 9 are respectively provided with a hook surface and a suede surface of a velcro. When winding the optical cable, place the head end of the optical cable at the notch 4 aligned with the outer surface of the cylindrical roller, move the second slider 8 to the notch 4, and use the second strap 9 on the second slider 8 Through the gap 4, the head end of the optical cable is bundled on the outer wall of the cylindrical roller, and the velcro on the strap can prevent the strap from loosening. After the head end of the optical cable is bundled, the head end of the optical cable does not move any more, and the optical cable can be easily wound, which helps to reduce the difficulty of operation when storing the optical cable.

Since the lengths of optical cables used in various substations are different, when carrying various lengths of optical cables, it is best to ensure that the optical cables can be wrapped around the reel, so as to ensure that the bending angle of the end of the optical cable is relatively small, and prevent the end of the optical cable from being pulled from the binding band. In the case of breaking free, or the end of the optical cable is lifted and the optical fiber protruding from the end of the optical cable is still bundled by the binding tape, causing the optical fiber to be excessively bent and damaged. In order to make optical cables of various lengths fully wound on the reel, the utility model can adopt the following structure: the cylindrical roller includes an outer cylinder 10 and an inner cylinder 11 which are nested with each other, and one end of the outer cylinder 10 is connected to the first The baffle plate 2 is connected, and one end of the inner cylinder 11 is connected with the second baffle plate 3, and the inner wall of the outer cylinder 10 is provided with a keyway 12 along the axial direction, and a key 13 is installed in the keyway 12, and the key 13 is connected with the inner cylinder 11. This structure makes the length of the cylindrical roller adjustable, so that the maintenance personnel can adjust the wire capacity of the reel according to the length of the optical cable to be wound, so as to ensure that the optical cable can be wrapped completely on the reel.

In order to locate the relative position of the inner tube 11 and the outer tube 10 in the utility model, bumping beads 14 can be arranged on the outer wall of the inner tube 11 , and a plurality of limit holes 15 cooperating with the bumping beads 14 can be set on the inner wall of the outer tube 10 .
