[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] like Figure 1 and Figure 2 As shown, in the first aspect, the embodiment of the present application provides an optical fiber storage device, including a frame 100 and a plurality of optical fiber storage mechanisms, wherein:

[0041] The frame 100 is provided with supporting columns 110 and a plurality of connecting beams 120 , and the plurality of supporting columns 110 and the plurality of connecting beams 120 are connected to form a frame structure.

[0042] The optical fiber storage mechanism includes a bearing structure 200, a fiber winding structure 300 and a locking structure 400. The fiber winding structure 300 is arranged on the bearing structure 200. The bearing structure 200 is slidably assembled on the supporting column 110. The bearing structure 200 can slide relative to the supporting column 110 to change the height of the bearing structure 200. The locking structure 400 is used to fix the bearing structure 200 on the supporting column 110.

[0043] The support column 110 and the connecting beam 120 can be made of the same material. For example, the support column 110 and the connecting beam 120 can be made of metal material or high-strength composite material. In a specific example, the support column 110 and the connecting beam 120 are both aluminum profiles with grooves on four sides. The aluminum profile has high strength and can achieve stable support, and the aluminum profile is light in weight, which is convenient for moving the optical fiber storage mechanism. The processing technology of the aluminum profile with grooves on four sides is mature and easy to process and manufacture.

[0044] The support column 110 and the connection beam 120 are fixedly connected. For example, the support column 110 and the connection beam 120 can be fixedly connected by welding or bolting.

[0045] The length direction of the supporting column 110 is the vertical direction, and the length direction of the connecting beam 120 can be the horizontal direction or can be inclined relative to the horizontal direction.

[0046] The support columns 110 and the connecting beams 120 are connected to form a frame structure. Figure 2 As shown, in a specific example, the length direction of the support column 110 is the vertical direction, the length direction of the connecting beam 120 can be the horizontal direction, and the outer contour of the frame structure formed by connecting the support column 110 and the connecting beam 120 is a cube shape. Figure 2 In the embodiment, there are four supporting columns 110, which are arranged in a matrix shape. Among the four supporting columns 110, a connecting beam 120 is connected between the bottoms of two adjacent supporting columns 110, and a connecting beam 120 is connected between the tops of two adjacent supporting columns 110, so that a stable rectangular parallelepiped frame structure can be formed by connecting four supporting columns 110 and eight connecting beams 120. Furthermore, a larger number of connecting beams 120 can be connected between two adjacent supporting columns 110 to improve the support stability of the frame structure.

[0047] The bearing structure 200 may be a plate-shaped bearing structure 200 , a frame-shaped bearing structure 200 , or a bearing structure 200 that combines a plate and a frame.

[0048] A plurality of optical fiber storage mechanisms are provided in the optical fiber storage device, so that the optical fibers can be stored in partitions, which is convenient for the maintenance and management of the optical fibers. The bearing structure 200 of the optical fiber storage mechanism can slide relative to the supporting column 110, and can be fixed on the column by the locking structure 400, so that the distance between adjacent bearing structures 200 can be adjusted according to the demand, and thus adjusted according to the space required by the optical fiber storage mechanism on the bearing structure 200, which is conducive to improving the space utilization of the optical fiber storage device. It can be seen from the above that the above-mentioned optical fiber storage device can adjust the space between adjacent bearing structures 200 to make adaptive adjustments according to the optical fiber storage requirements, which is convenient for improving the space utilization, avoiding excessive stacking of optical fibers in the longitudinal direction, and storing the optical fibers in partitions through multiple optical fiber storage mechanisms, which is convenient for the later management and maintenance of the optical fibers.

[0049] Furthermore, when the amount of optical fiber to be stored in the optical fiber storage device is small, the position of each supporting structure 200 can be adjusted so that the distance between adjacent supporting structures 200 is relatively small, for example, the supporting structures 200 are stacked from bottom to top (such as Figure 3 As shown), the upper space of the optical fiber storage device is freed up to save space occupied by the optical fiber storage device.

[0050] like Figure 1 and Figure 4 As shown, in an optional design, the fiber winding structure 300 includes a fiber storage unit box, the fiber storage unit box includes a line inlet 311 and a line outlet 312, a fiber winding drum 320 is arranged in the fiber storage unit box, and the fiber storage unit box is placed on the bearing structure 200. The fiber storage unit box is used to store optical fibers, and the optical fibers enter through the line inlet 311 of the fiber storage unit box, and after winding redundant optical fibers on the fiber winding drum 320, they extend out through the line outlet 312 of the fiber storage unit box. The fiber storage unit box plays a dust-proof and protective role for the optical fibers. The fiber storage unit box is placed on the bearing structure 200, which is convenient for addition and removal. In the case of needing to accommodate more optical fibers, more fiber storage unit boxes can be placed on the bearing structure 200; and in the case of relatively less optical fiber accommodation requirements, the fiber storage unit boxes may not be placed on the bearing structure 200, so that the distance between the unused bearing structures 200 can be adjusted to be relatively smaller, so as to further reduce space occupation.

[0051] like Figure 4 As shown, the fiber storage unit box includes a box body 310, a line inlet 311 and a line outlet 312 are arranged on opposite sides of the box body 310, and an inspection opening 313 is arranged on the front side of the box body 310. The inspection opening 313 can be connected to the line inlet 311 or not; the inspection opening 313 can be connected to the line outlet 312 or not. Figure 4In the fiber storage unit box shown, the inspection opening 313 is connected to both the outlet 312 and the inlet 311. A dustproof door body 314 is provided at the inspection opening 313. The bottom of the dustproof door body 314 is hinged to the box body 310. A buckle 315 is provided on the top of the dustproof door body 314. The dustproof door can rotate relative to the box body 310 and can be connected to the box body 310 through the buckle 315, so that the dustproof door can be locked and opened. The provision of the inspection opening 313 facilitates the maintenance and management of the optical fibers located in the fiber storage unit box from the front side. Figure 4 In the fiber storage unit box shown, buckles 315 are respectively provided at both ends of the top of the dustproof door body 314.

[0052] A positioning hook 316 may also be provided on the box body 310. For example, multiple positioning hooks 316 are provided in both the line inlet 311 and the line outlet 312. Multiple positioning hooks 316 are provided on the side wall of the line inlet 311 away from the inspection opening 313. Multiple positioning hooks 316 are provided in sequence in the vertical direction. Multiple positioning hooks 316 are provided on the side wall of the line outlet 312 away from the inspection opening 313. Multiple positioning hooks 316 are provided in sequence in the vertical direction. The positioning hooks 316 can be used to position the optical fiber, which facilitates the management of the optical fiber.

[0053] The fiber winding tube 320 includes a column and a baffle. One end of the column along the axial direction is connected to the inner wall of the box 310. The other end of the column along the axial direction is provided with a baffle. The cross-sectional area of ​​the baffle is larger than the cross-sectional area of ​​the column. The optical fiber can be wound on the column. The baffle and the inner wall of the box 310 respectively play a certain degree of stopping role for the optical fiber wound on the column on opposite sides. The column can be cylindrical or elliptical.

[0054] One or more fiber winding drums 320 may be disposed in the box 310. Figure 4 The fiber storage unit box shown in FIG. 1 is provided with two fiber winding drums 320. In other embodiments, the fiber storage unit box may also be provided with more than two fiber winding drums 320.

[0055] In the case where the fiber winding structure 300 includes a fiber storage unit box, an anti-skid layer may be provided on the top surface of the bearing structure 200, and the anti-skid layer may increase the friction between the fiber storage unit box and the bearing structure 200, thereby improving the placement stability of the fiber storage unit box on the bearing structure 200. In another embodiment, a limiting groove may be provided on the top surface of the bearing structure 200, and a part of the bottom area of ​​the fiber storage unit box is extended into the groove, and the inner wall of the groove plays a certain degree of limiting role for the fiber storage unit box. In yet another embodiment, a first magnetic patch may be attached to the top surface of the bearing structure 200, and a second magnetic patch may be attached to the bottom of the fiber storage unit box, and the first magnetic patch and the second magnetic patch are magnetically attracted to each other, thereby improving the placement stability between the fiber storage unit box and the bearing structure 200.

[0056] In another embodiment, the fiber winding structure 300 includes a fiber winding drum 320, which is detachably connected to the bearing structure 200. In this arrangement, the fiber winding structure 300 does not include a fiber storage unit box, but includes a fiber winding drum 320, which is directly installed on the bearing structure 200, and the fiber winding drum 320 is detachably connected to the bearing structure 200. In this arrangement, the amount of optical fiber carried on the bearing structure 200 is not limited by the inner cavity space of the fiber storage unit box, and the space utilization rate is higher. Since the fiber winding drum 320 is detachably connected to the bearing structure 200, fiber winding drums 320 of different structural sizes can be installed on the bearing structure 200 according to demand, and the flexibility of demand adaptation is high. Since the fiber winding drum 320 is detachably connected to the bearing structure 200, when the demand for optical fiber storage is low, the fiber winding drum 320 can be removed from the bearing structure 200, so that the distance between the unused bearing structures 200 can be adjusted to be relatively smaller, so as to further reduce space occupation.

[0057] The fiber winding tube 320 may include a column, a connecting plate and a baffle, and the two ends of the column in the axial direction may be connected to the connecting plate and the baffle respectively, and the connecting plate is detachably connected to the bearing structure 200. The connection between the connecting plate and the bearing structure 200 may be plug-in, clamped, screwed, etc. Exemplarily, the connecting plate may be connected to the bearing structure 200 by bolts or pins.

[0058] In an alternative design, Figure 5 As shown, the optical fiber storage device further includes a flexible dustproof layer 330, which is disposed around the outer side of the fiber winding structure 300, and the flexible dustproof layer 330 is detachably connected to two adjacent supporting structures 200. The flexible dustproof layer 330 can be a plastic film or a dustproof cloth. The flexible dustproof layer 330 is connected to the two supporting structures 200, so that a dustproof chamber is formed between the two supporting structures 200 through the flexible dustproof layer 330.

[0059] The flexible dustproof layer 330 can be a strip-shaped structure, so that one end of the flexible dustproof layer 330 can be wrapped around the periphery of the frame 100 for a circle and then fixed to the other end, so that the flexible dustproof layer 330 is surrounded by the outside of the frame 100, and the upper supporting structure 200 of the two adjacent supporting structures 200 is detachably connected to the top area of ​​the flexible dustproof layer 330, and the lower supporting structure 200 is detachably connected to the bottom area of ​​the flexible dustproof layer 330, so that the flexible dustproof layer 330 is surrounded by the outside of the fiber winding structure 300 and is respectively connected to the two supporting structures 200.

[0060] In another configuration, the flexible dustproof layer 330 may be a cylindrical structure, which is disposed around the outside of the fiber winding structure 300 and is located inside the frame 100. The upper supporting structure 200 of the two adjacent supporting structures 200 is detachably connected to the top area of ​​the flexible dustproof layer 330, and the lower supporting structure 200 is detachably connected to the bottom area of ​​the flexible dustproof layer 330, so that the flexible dustproof layer 330 is disposed around the outside of the fiber winding structure 300 and is respectively connected to the two supporting structures 200.

[0061] Since the flexible dustproof layer 330 is flexible and can be deformed, even if the distance between the two supporting structures 200 is adjusted within a certain range, the dustproof effect of the flexible dustproof layer 330 is not affected.

[0062] In another optional design, the bearing structure 200 is a rectangular plate-shaped structure, and four flexible dustproof layers 330 are arranged between two adjacent bearing structures 200. The four flexible dustproof layers 330 and the two adjacent bearing structures 200 are arranged to form a rectangular dustproof chamber, and the fiber winding tube 320 is located in the dustproof chamber. In this setting, the optical fiber in the dustproof chamber can be inspected by opening one of the flexible dustproof layers 330, without removing all the flexible dustproof layers 330, which facilitates the inspection and maintenance of the optical fiber and improves the operation efficiency.

[0063] In other embodiments, among two adjacent supporting structures 200, only the upper supporting structure 200 is connected to the flexible dustproof layer 330, so that the bottom of the flexible dustproof layer 330 naturally hangs to the outside of the lower supporting structure 200, thereby forming a dustproof chamber between the two supporting structures 200.

[0064] In an optional design, the outer side of the bearing structure 200 is provided with a first magnetic attraction structure, and the flexible dustproof layer 330 is provided with a second magnetic attraction structure, and the first magnetic attraction structure is magnetically connected to the second magnetic attraction structure. One of the first magnetic attraction structure and the second magnetic attraction structure can be a magnetic part, and the other can be a metal part that can be adsorbed by the magnetic part, or both can be magnetic parts, and the two magnetic parts are magnetically attracted to each other. The provision of the first magnetic attraction structure and the second magnetic attraction structure facilitates the installation and removal of the flexible dustproof layer 330, is convenient to operate, and has high installation and removal efficiency.

[0065] The first magnetic structure can be fixed to the outside of the bearing structure 200 by pasting. The second magnetic structure can be pasted on the flexible dustproof layer 330, or can be separated from the flexible dustproof layer 330. In the case where the second magnetic structure is separated from the flexible dustproof layer 330, in the process of fixing the flexible dustproof layer 330 to the bearing structure 200, the second magnetic structure is placed at one end of the flexible dustproof layer 330 away from the first magnetic structure, so that when the first magnetic structure and the second magnetic structure are adsorbed, the flexible dustproof layer 330 is clamped and fixed between the first magnetic structure and the second magnetic structure.

[0066] It is understandable that the bearing structure 200 and the flexible dustproof layer 330 may be connected by other detachable connection methods, such as Velcro, hooks, and other structural connections.

[0067] like Figures 6 to 10 As shown, in an optional design, the bearing structure 200 is connected with an adapter 210, and the adapter 210 is provided with a through hole 211; the locking structure 400 includes a slider 410, a stud 420 and a locking portion 430, and the support column 110 is provided with a slide groove 111 along the vertical direction, and the slider 410 is slidably installed in the slide groove 111, and the size of the slider 410 is larger than the opening of the slide groove 111, and the slider 410 is connected with the stud 420, and the stud 420 extends out of the opening of the slide groove 111 and passes through the through hole 211, and the locking portion 430 is provided with a threaded hole, and the locking portion 430 is located on the side of the adapter 210 away from the slider 410, and the locking portion 430 is screwed with the stud 420 to connect the adapter 210 and the support column 110. It is worth noting that the opening of the slide groove 111 has a length direction and a width direction, the length direction is the vertical direction, and the width direction is the horizontal direction. In the width direction of the opening of the slide slot 111, the size of the slider 410 is larger than the size of the opening of the slide slot 111, so that the slider 410 can move along the length direction of the slide slot 111, and the slider 410 will not be separated from the slide slot 111 in the horizontal direction. The locking portion 430 is sleeved on the stud 420, and the locking portion 430 is tightened, so that the support column 110 and the adapter 210 can be clamped and fixed by the slider 410 and the locking portion 430, so that the bearing structure 200 is fixedly connected to the support column 110. The locking portion 430 is loosened, so that the distance between the locking portion 430 and the slider 410 increases, so that the bearing structure 200 can be moved in the vertical direction, and the height of the bearing structure 200 can be adjusted, thereby changing the distance between two adjacent bearing structures 200.

[0068] The support column 110 can be made of an aluminum profile with grooves on four sides, and the groove on one side can be used to form a slide groove 111. The slide groove 111 is a T-shaped groove, and the width of its internal space is greater than the width of the opening, so that the slider 410 can move longitudinally along the slide groove 111 and will not leave the slide groove 111 in the horizontal direction, so that the slide groove 111 has a better guiding and positioning effect on the slider 410.

[0069] In an optional design, as shown in Figure 10, the adapter 210 includes a transverse plate 212, a longitudinal plate 213 and a reinforcing plate 214. The transverse plate 212 is vertically arranged and connected to the longitudinal plate 213. The reinforcing plate 214 is respectively connected to the transverse plate 212 and the longitudinal plate 213. The transverse plate 212 is detachably connected to the bearing structure 200, and the longitudinal plate 213 is provided with a through hole 211. The transverse plate 212 is located at the bottom of the bearing structure 200, the top surface of the transverse plate 212 is in contact with the bottom surface of the bearing structure 200, one end of the transverse plate 212 is connected to the top of the longitudinal plate 213, and the longitudinal plate 213 covers a part of the area outside the opening of the slide slot 111 and is in contact with the supporting column 110. The reinforcing plate 214 is perpendicular to the transverse plate 212 and the longitudinal plate 213, and the reinforcing plate 214 is respectively connected to the transverse plate 212 and the longitudinal plate 213. The reinforcing plate 214 improves the connection strength between the transverse plate 212 and the longitudinal plate 213, and can reduce the probability of relative bending of the transverse plate 212 and the longitudinal plate 213 to a certain extent. In a specific embodiment, the reinforcing plate 214 is a plate body of a right-angled triangle structure, one right-angled side of which is connected to the edge of the transverse plate 212, and the other right-angled side is connected to the edge of the longitudinal plate 213. The transverse plate 212 and the bearing structure 200 can be connected by a first bolt 500. A threaded hole can be provided on the bearing structure 200, and a through hole 211 is provided on the transverse plate 212. The first bolt 500 passes through the through hole 211 and is screwed into the threaded hole, thereby connecting the transverse plate 212 to the bearing structure 200. In a specific embodiment, the through hole 211 on the transverse plate 212 can be an oblong hole (or a waist-shaped hole).

[0070] In an alternative embodiment, Figure 6As shown, the bearing structure 200 includes a carrier plate 220, and the carrier plate 220 is connected to the cross plate 212. In another optional embodiment, the bearing structure 200 includes a carrier plate 220 and a reinforcement frame, and the reinforcement frame is formed by connecting a plurality of reinforcement beams 230, and the edge area of ​​the carrier plate 220 overlaps the top surface of the reinforcement beam 230 and is connected to the reinforcement beam 230. The reinforcement beam 230 is connected to the cross plate 212. In this arrangement, the carrier plate 220 and the reinforcement frame can be made of different materials. For example, the carrier plate 220 can be made of a wooden board, a metal plate or a resin board, and the reinforcement frame can be made of an aluminum profile.
