Optical fiber is a fiber made of glass or plastic, and is used for long distance information transmission in daily life because the transmission loss of light in the optical fiber is much lower than the transmission loss of electricity in the electric wire. The optical fiber must be covered by a protective structure before use, and the covered cable is called an optical cable. The protective structure enables the optical fiber to bend without breaking.
Excessive stretching, bending, squeezing or other impact forces on the cable can cause damage to the fiber, thereby affecting its performance. Accordingly, the cable should be stored in an appropriate manner. At present, a spool is generally adopted to spool an optical cable, and the diameter of an inner barrel of the spool is not smaller than the minimum bending radius of the optical cable, otherwise, the optical fiber is damaged and the performance of the optical fiber is affected.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Considering the larger storage capacity, the pressure of the fiber winding disc is larger, and the optical cable on the disc is contacted with the inner cylinder by larger side pressure. The inner cylinder of the optical line disc is formed by splicing straight wood strips, and the splicing parts among the wood strips are excessive in turning and even the edges of the wood strips are exposed due to lower processing degree, as shown in fig. 1 a. For a typical cable or other cable, the turning transition of the side pressure is not significantly affected. For the optical cable, the inner tube which is bent and transited in such a way is sensitive to bending, so that under the condition of larger side pressure, the optical cable forms more serious microbending in the lateral direction, which may cause the increase of the optical loss of the inner fiber.
The invention adopts the bamboo inner cylinder, and the natural curved surface of the bamboo is utilized to form the petal-shaped inner cylinder section by the bamboo strip, 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 coiled on the inner barrel, thereby avoiding turning contact, avoiding microbending of the optical cable and reducing the increase of optical loss caused by side pressure.
The invention provides an optical cable wire spool, which comprises a spool inner barrel and two side baffle spools;
the inner barrel of the tray 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 fixedly connected with one side baffle plate respectively;
for each straight bamboo strip, the inner surface, the outer surface and the two side surfaces are smooth, the outer surface keeps an outward 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 arc transition without sharp angle so as to prevent the optical cable from being cut.
Referring to the drawings, the optical cable wire spool provided by the invention comprises a spool inner barrel 1 and two side baffle disks 2, wherein the spool inner barrel 1 is formed by encircling a plurality of parallel straight bamboo strips 11, and a first end and a second end of each straight bamboo strip 11 are fixedly connected with one side baffle disk 2 respectively; the material of each side baffle disc 2 is selected from willow or fir, and pine is forbidden to be used, because the bending strength, compressive strength, shock resistance and other strength of the willow or fir can meet the use requirement of the wire spool, while the pine is softer after degreasing, has lower bearing capacity in terms of load, is forbidden to collide, is easy to have pits, is not compact enough, is easy to deform, crack, turn up and corrode, and therefore cannot meet the use requirement of the optical fiber wire spool.
For each straight bamboo strip 11, the inner surface 111 and the outer surface 112 are provided (the inner surface 112 and the outer surface 112 are determined according to the structural characteristics of the bamboo, the inner surface 111 and the outer surface 112 of the bamboo are respectively the inner surface 111 and the outer surface 112 of the straight bamboo strip 11), and two side surfaces 113, each side surface 113 is respectively connected with the inner surface 111 and the outer surface 112, the two side surfaces 113 can be parallel to each other or can be at a certain angle, the inner surface 111 can be a plane, the inner surface 111 can be perpendicular to the side surfaces 113, the inner surface 112 and the outer surface 112 are smooth, the outer surface 112 keeps a cambered shape, namely, the outer surface 112 is a curved surface, preferably a cambered surface, the outer surface 112 is used for being contacted with an optical cable, the outer surface is cambered, so the pressure resistance is strong, and the joint of the outer surface 112 and each side surface 113 is respectively processed into a cambered transition without a sharp angle so as to prevent the optical cable from being cut; the single straight bamboo strip 11 has excellent mechanical properties and can resist the compression force of the optical cable with great weight and the tensile force of the side baffle discs 2 at the two ends. The straight bamboo strips 11 are preferably processed from natural bamboo, and the processed product is fast and can be conveniently applied to the wire reel.
The straight bamboo strips 11 forming the inner barrel 1 of the tray are distributed circumferentially, so that the cross section of the inner barrel 1 of the tray is petal-shaped, and all contact surfaces with the optical cable are cambered surfaces, thereby avoiding the optical cable from forming microbending. The straight bamboo strips 11 are distributed on the circle, so that the enclosed inner tray barrel 1 is stable in structure, can resist deformation from all directions, is not easy to crush, and is long in service life. The arcuate line of the outer surface 112 of the straight bamboo strip 11 is fitted as much as possible to form a circle, so that the inner drum 1 of the tray has higher stability, therefore, the invention prefers that the maximum width of each straight bamboo strip 11 is 30 mm-60 mm, and the maximum thickness is 6 mm-12 mm, and by adopting the straight bamboo strip 11 with the size, the processing is convenient, and the outer surface 112 can be fitted as much as possible to form a circle, thereby meeting the winding requirement of the optical cable. Any part of the straight bamboo strip 11 contacted with the optical cable is smooth, and the optical cable is not damaged.
Further, referring to fig. 6, as another preferred embodiment, for any adjacent two straight bamboo strips 11, the side face of each straight bamboo strip 11 is cut to form a boss 114, and the boss 114 of the side face of one straight bamboo strip 11 rests on the boss 114 of the other straight bamboo strip 11. The width and thickness of the boss 114 may be determined by finite element analysis to facilitate stress, as the case may be. Thus, after the optical cable reel is stored on the wire reel, the pressure born by one straight bamboo strip 11 can be transmitted to the other adjacent straight bamboo strip 11 through the boss 114, and 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, and the straight bamboo strips are not singly stressed separately, but form a stressed network which jointly resists the pressure (mainly resists radial force) of the optical cable, so that the radial stability of the inner barrel 1 of the reel is good.
In addition, for any two adjacent straight bamboo strips 11, the outer edge 115 of one boss 114 abuts against the side face of the other straight bamboo strip 11, so that after the inner drum 1 of the disc is pressed by the optical cable more and more tightly, the diameter of the inner drum is reduced, the straight bamboo strips 11 on the whole circle can bear the pressure of the optical cable together to form a stressed network which jointly resists the pressure (mainly the circumferential force) of the optical cable, and the circumferential stability of the inner drum 1 of the disc is good.
Further, each of the side catch plates 2 includes an outer plate 21 and an inner plate 22 fixedly connected together, which are both circular plates and coaxially disposed, the diameter of the inner plate 22 being smaller than that of the outer plate 21; the two inner discs 22 are located between the two outer discs 21; each end of the straight bamboo strip 11 is respectively rested on an outer circumferential surface of one of the inner disks 22 and fixed on the outer circumferential surface of the inner disk 22 by nails. This is because if the straight bamboo strip 11 is nailed along its length direction, the straight bamboo strip 11 is easy to split, and the straight bamboo strip 11 is also thinner, and after splitting, it will be easy to drop from the side catch plate 2, so after the end of the straight bamboo strip 11 is placed on the outer circular surface of the inner plate 22, the nail is driven into the end of the straight bamboo strip 11 along the direction of the outer surface 112 of the straight bamboo strip 11 to the inner surface 111, so that the end of the straight bamboo strip 11 is not easy to split, and in this way, the straight bamboo strip 11 and the inner plate 22 of the side catch plate 2 can be well connected together, thereby facilitating the assembly of the wire spool. The side guard 2, and in particular the inner plate 22, of the present invention is made of wood, and is also convenient for driving nails.
Further, the outer plate 21 includes an outer plate and an inner plate fixedly connected together, the inner plate is located between the outer plate and the inner plate 22, the outer plate is made up of a plurality of first wooden strips parallel to each other, the inner plate is made up of a plurality of second wooden strips parallel to each other, and the first wooden strips are perpendicular to the second wooden strips. Through this kind of crisscross batten 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 for the frame that looses, and splice through the batten moreover, the preparation is also more convenient. Preferably, the first wood strip and the second wood strip are fixedly connected through closely-distributed nails, so that the outer layer plate and the inner layer plate are fixedly connected together. When nails are driven into the outer disc 21, a part of nails can be distributed in the circular projection area of the inner barrel on the outer disc 21, and then a part of nails can be distributed in the circular ring area of one section at the edge of the outer disc 21, so that the first batten and the second batten can be well fixed. The nails are not required to be densely distributed on the whole outer disc 21, so that the operation is complicated, too many nails are nailed, the wood strips can be cracked easily, the strength of the outer disc 21 can be reduced, the outer disc 21 is damaged easily, and more importantly, the tips of the nails are likely to be exposed to the inner side of the side baffle disc, so that the risk of damaging an optical cable is caused.
Further, the outer and inner discs 21, 22 each have a central through hole where a central post 23 is mounted and is a close fit with both the outer and inner discs 21, 22. The outer disc 21 and the inner disc 22 can be quickly coaxially assembled together through the center post 23, and the outer disc 21 is prevented from being damaged due to uneven stress of the outer disc 21 caused by the non-coaxiality of the outer disc 21 and the inner disc 22 after the optical cable disc is stored on the inner drum 1 of the optical disc.
Furthermore, the invention also comprises a plurality of metal connecting pull rods 3, wherein 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 a metal framework of the wire spool, so that the effect of improving the overall strength of the wire spool can be achieved. Each end of each metal connecting pull rod 3 passes through one side baffle plate 2 and each end is provided with a locknut 4. After the optical cable is stored on the inner barrel 1 of the disc tool, a cylindrical structure is formed, two ends of the cylindrical structure also have certain extrusion force on the inner side of the outer disc 21 of the side blocking disc 2, namely, the trend of pushing the outer disc 21 outwards is provided, so that the side blocking disc 2 needs to be fastened by matching the metal connecting pull rod 3 with the locknut 4, and the extrusion force of the optical cable in the long-term use process is prevented from leading the side blocking disc 2 to fall outwards. Preferably, the outer surface 112 of each of the metal connecting rods 3 is painted with a black rust-preventing paint to perform rust-preventing treatment, so that the metal connecting rods 3 are prevented from being rusted to affect the service performance in long-term use.
Further, the inner drum support plate (5) is circular and positioned between the two side baffle plates (2), and each straight bamboo strip (11) is placed on the outer circular surface of the inner drum support plate (5) and fixed on the outer circular surface of the inner drum support plate (5) through nails. Each metal connecting pull rod 3 respectively passes through the inner barrel supporting disk 5 of the disk tool. The diameter of the inner tub supporting plate 5 of the dish is equal to the outer diameter of the inner plate 22 of the side catch plate 2, so that the nails are convenient to fix the straight bamboo strips 11 on the inner plate 22 and the inner tub supporting plate 5 of the dish, so that the straight bamboo strips 11 maintain a straight state without bending. The tray inner tub supporting tray 5 can play a role of supporting the tray inner tub 1 so that the tray inner tub 1 is not easily deformed.
