Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Considering larger storage capacity, the pressure of the fiber winding disc is larger, and the optical cables on the disc are contacted with the inner cylinder at larger side pressure. The inner barrel of the light panel is generally formed by splicing straight battens, and due to the low processing degree, the spliced parts between the battens are excessively bent, even the edges of the battens are exposed, as shown in fig. 1 a. For a common cable or other cables, the side pressure formed turning transition does not cause obvious sound. For the optical cable, because the inner optical fiber is sensitive to bending, the inner tube bent in the transition way can cause severe microbending of the optical cable in the lateral direction under large lateral pressure, which may result in increased optical loss of the inner optical fiber.
The present invention adopts bamboo inner cylinder, and utilizes the natural curved surface of bamboo to form petal-shaped inner cylinder section by bamboo strips, as shown in figure 1 b. Each bamboo strip keeps an outward convex arc line and forms lateral arc surface contact with the optical cable wound on the inner tube, so that turning contact is avoided, micro bending of the optical cable is avoided, and increase of optical loss caused by side pressure is reduced.
The invention provides an optical cable wire spool, which comprises an inner barrel and two side baffle discs;
the inner drum of the disc is formed by enclosing a plurality of parallel straight bamboo strips, and the first end and the second end of each straight bamboo strip are respectively and fixedly connected with one side baffle disc;
for each straight bamboo strip, the straight bamboo strip is provided with an inner surface, an outer surface and two side surfaces, the inner surface and the outer surface are smooth, the outer surface keeps an outward convex arc line, the outer surface is used for keeping arc line contact with the optical cable, and the joint of the outer surface and each side surface is respectively processed into an arc transition without a sharp angle so as to prevent the optical cable from being cut.
Referring to the attached drawings, the optical cable wire spool provided by the invention comprises a wire spool inner barrel 1 and two side baffle disks 2, wherein the wire spool inner barrel 1 is formed by enclosing a plurality of parallel straight bamboo strips 11, and the first end and the second end of each straight bamboo strip 11 are respectively fixedly connected with one side baffle disk 2; the side baffle discs 2 are made of willow or cedar, pine is forbidden because the bending strength, compression strength, shock strength and other strength of the willow or the cedar can meet the use requirement of the wire spool, and the pine is soft after degreasing, has low bearing capacity in the aspect of loading, cannot be collided, is easy to have a concave hole, is not compact enough, and is easy to deform, crack, turn over and corrode, so the use requirement of the optical fiber wire spool cannot be met.
Each straight bamboo strip 11 has an inner surface 111, an outer surface 112 (inner and outer surfaces 112 are determined according to the structural characteristics of bamboo itself, inner and outer surfaces 111, 112 of bamboo are also inner and outer surfaces 111, 112 of straight bamboo strip 11 respectively) and two side surfaces 113, each side surface 113 connects inner and outer surfaces 111, 112 respectively, two side surfaces 113 may be parallel to each other or at an angle, the inner surface 111 may be planar, the inner surface 111 may be perpendicular to the side 113, both the inner and outer surfaces 112 may be smooth and the outer surface 112 may maintain a domed shape, i.e., the outer surface 112 is curved, preferably curved, and the outer surface 112 is adapted to contact the fiber optic cable, the outer surface is arched, so that the pressure resistance is strong, and the joints of the outer surface 112 and each side surface 113 are respectively processed into arc-shaped transition without sharp corners so as to prevent the optical cable from being cut; the single straight bamboo strip 11 has excellent mechanical properties and can resist the pressure of a heavy optical cable and the tensile force of the side baffle discs 2 at two ends. The straight bamboo strips 11 are preferably made of natural bamboos, are processed quickly and can be conveniently applied to the wire spool.
The straight bamboo strips 11 forming the inner barrel 1 of the disc device are distributed in a circumferential manner, so that the cross section of the inner barrel 1 of the disc device is in a petal shape, and all contact surfaces with the optical cable are in arc surface contact, thereby preventing the optical cable from forming micro-bending. The straight bamboo strips 11 are distributed on a circle, so that the inner barrel 1 of the disc tool formed by enclosing has stable structure, can resist deformation from all directions, is not easy to crush and has long service life. The arch line of the outer surface 112 of the straight bamboo batten 11 is fitted to form a circle as much as possible, so that the inner barrel 1 of the dish is more stable, therefore, the maximum width of each straight bamboo batten 11 is preferably 30-60 mm, the maximum thickness of each straight bamboo batten 11 is preferably 6-12 mm, and the straight bamboo battens 11 with the size are adopted, so that the processing is convenient, the outer surface 112 can be fitted to form a circle as much as possible, and the winding requirement of the optical cable is met. Any part of the straight bamboo strip 11, which is in contact with the optical cable, is smooth, so that the optical cable cannot be damaged.
Further, referring to fig. 6, as another preferable scheme, for any two adjacent straight bamboo strips 11, bosses 114 are cut and formed on the side surface of each straight bamboo strip 11, and the boss 114 on the side surface of one straight bamboo strip 11 is laid on the boss 114 of the other straight bamboo strip 11. The width and thickness of the boss 114 are determined according to specific conditions, and can be determined after finite element analysis, so as to facilitate stress. After the optical cable coil is stored on the wire spool, the pressure borne by one straight bamboo strip 11 can be transmitted to the other adjacent straight bamboo strip 11 through the boss 114, any two adjacent straight bamboo strips 11 have interaction force, so that the straight bamboo strips 11 on the whole circle can bear the pressure of the optical cable together, the straight bamboo strips and the straight bamboo strips are not separately stressed but form a stress network for resisting the pressure of the optical cable together (mainly resisting radial force), and the radial stability of the inner barrel 1 of the coil is good.
In addition, for any two adjacent straight bamboo strips 11, the outer edge 115 of one boss 114 abuts against the side surface of the other straight bamboo strip 11, so that after the inner barrel 1 of the coil device is pressed by the optical cable more and more, the straight bamboo strips 11 on the whole circle have the tendency of diameter reduction, the straight bamboo strips 11 on the whole circle can bear the pressure of the optical cable together, and form a stress network which resists the pressure of the optical cable together (mainly resists the circumferential force), so that the circumferential stability of the inner barrel 1 of the coil device is good.
Further, each side baffle disc 2 comprises an outer disc 21 and an inner disc 22 which are fixedly connected together, wherein the outer disc 21 and the inner disc 22 are circular discs and are coaxially arranged, and the diameter of the inner disc 22 is smaller than that of the outer disc 21; two of the inner discs 22 are located between two of the outer discs 21; each end of the straight bamboo strips 11 respectively rests on the outer circumferential surface of one of the inner discs 22 and is fixed to the outer circumferential surface of the inner disc 22 by nails. This is because if the straight bamboo strips 11 are nailed along the length direction thereof, the straight bamboo strips 11 are easily cracked, and the straight bamboo strips 11 are also thin, and the straight bamboo strips 11 are easily detached from the side catch tray 2 after being cracked, so that nails are driven into the inner surface 111 along the outer surface 112 of the straight bamboo strips 11 at the ends of the straight bamboo strips 11 after the ends of the straight bamboo strips 11 are placed on the outer circumferential surface of the inner tray 22, so that the ends of the straight bamboo strips 11 are not easily cracked, and thus the straight bamboo strips 11 and the inner tray 22 of the side catch tray 2 can be well connected together, and the assembly of the wire spool is facilitated. The side baffle disc 2, particularly the inner disc 22, is made of wood, and is convenient for nailing.
Further, the outer disc 21 includes an outer plate and an inner plate fixedly connected together, the inner plate is located between the outer plate and the inner disc 22, the outer plate is formed by splicing a plurality of first battens parallel to each other, the inner plate is formed by splicing a plurality of second battens parallel to each other, and the first battens and the second battens are perpendicular to each other. Through this kind of vertically and horizontally staggered's stuff structure, can help outer dish 21 to resist the collision in transport and transfer, transportation for it can keep the stability of structure, is difficult to loose the frame, and through the stuff concatenation, the preparation is also more convenient moreover. Preferably, the first wood strip and the second wood strip are fixedly connected through densely distributed nails, so that the outer layer plate and the inner layer plate are fixedly connected together. When the nails are driven into the outer disc 21, a part of the nails can be distributed in the circular projection area of the inner barrel on the outer disc 21, and then a part of the nails can be distributed in the circular ring area at one section of the edge of the outer disc 21, so that the first batten and the second batten can be well fixed. The nails do not need to be densely distributed on the whole outer disc 21, so that firstly, the operation is more complicated, secondly, the nails are driven too many, the wood strips are likely to crack, and the strength of the outer disc 21 is reduced, so that the outer disc 21 is likely to be damaged, and more importantly, the tips of the nails are likely to be exposed on the inner side of the side blocking disc, and the risk of damaging the optical cable is caused.
Further, the outer disc 21 and the inner disc 22 are both provided with a central through hole, and the central column 23 is installed at the central through hole and is tightly matched with the outer disc 21 and the inner disc 22. The central column 23 can quickly realize the coaxiality of the outer disc 21 and the inner disc 22 and the quick assembly together, and can prevent the damage of the outer disc 21 caused by the uneven stress of the outer disc 21 due to the different shafts of the outer disc 21 and the inner disc 22 after the optical cable disc is stored on the inner drum 1 of the disc tool.
Furthermore, the wire spool also comprises a plurality of metal connecting pull rods 3, the metal connecting pull rods 3 are parallel to the straight bamboo strips 11, and the metal connecting pull rods 3 can be regarded as metal frameworks of the wire spool and can play a role in improving the overall strength of the wire spool. Each end of each metal connecting pull rod 3 respectively penetrates through one side baffle disc 2 and each end is penetrated with a locknut 4. The optical cable is stored in the inner barrel 1 of the tray to form a cylindrical structure, and two ends of the cylindrical structure can also have certain extrusion force to the inner side of the outer disk 21 of the side retaining disk 2, namely the outer disk 21 tends to be pushed away outwards, so that the side retaining disk 2 needs to be fastened by matching the metal connecting pull rod 3 with the anti-loosening nut 4, and the side retaining disk 2 is prevented from falling outwards due to the extrusion force of the optical cable in the long-term use process. Preferably, the outer surface 112 of each metal connecting pull rod 3 is painted with black anti-rust paint for anti-rust treatment, so as to prevent the metal connecting pull rod 3 from rusting and affecting the service performance thereof in long-term use.
Further, a round tray inner barrel supporting plate 5 is arranged between the two side baffle plates 2, and each straight bamboo strip 11 is placed on the outer circular surface of the tray inner barrel supporting plate 5 and fixed on the outer circular surface of the tray inner barrel supporting plate 5 through nails. Each metal connecting pull rod 3 respectively penetrates through the disk inner barrel supporting plate 5.
