[0053] In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0054] Embodiment 1:

[0055] Embodiment 1 of the present utility model provides an optical cable reel with multiple slots on both sides, as Figure 1 shown, including: a first disk surface 1, a second disk surface 2, and a fiber coiling part 3, wherein: the first disk surface 1 is arranged on one side of the fiber coiling part 3, and the second disk surface 2 is arranged on the other side of the fiber coiling part 3.

[0056] In this embodiment, both the first disk surface 1 and the second disk surface 2 are circular, the fiber coiling part 3 is cylindrical, the end face on one side of the fiber coiling part 3 is connected to the center position of the first disk surface 1, and the end face on the other side of the fiber coiling part 3 is connected to the center position of the second disk surface 2; the axes of the first disk surface 1, the fiber coiling part 3, and the second disk surface 2 are consistent; the sizes of the first disk surface 1 and the second disk surface 2 are the same.

[0057] As Figure 1 shown, a first preset number of first fiber guiding ports 11 are arranged on the circumferential side of the first disk surface 1. One side of the first fiber guiding port 11 leads to the inside of the first disk surface 1, and the other side leads to the outside of the first disk surface 1; a first preset number of second fiber guiding ports 21 are arranged on the circumferential side of the second disk surface 2. One side of the second fiber guiding port 21 leads to the inside of the second disk surface 2, and the other side leads to the outside of the second disk surface 2.

[0058] As Figure 1 and Figure 2 shown, where Figure 2 is another optical cable reel with different numbers of fiber outlet ports.Figure 2 shows the situation when the optical cable is stored on the optical cable reel, and Figure 2 a protective shell is provided on the circumferential side of the optical cable reel in . In order to show the fiber coiling part 3 inside, part of the protective shell is hidden; the fiber coiling part 3 is used for coiling the optical cable on the side wall of the fiber coiling part 3; the first fiber guiding port 11 is used for guiding the optical cable out of the fiber coiling part 3 to the outside of the first disk surface 1 and docking with other optical cables; the second fiber guiding port 21 is used for guiding the optical cable out of the fiber coiling part 3 to the outside of the second disk surface 2 and docking with other optical cables.

[0059] In this embodiment, the first fiber guiding port 11 is arranged on the side wall of the circumferential side of the first disk surface 1 and extends towards the center of the first disk surface 1, and the second fiber guiding port 21 is arranged on the side wall of the circumferential side of the second disk surface 2 and extends towards the center of the second disk surface 2.

[0060] In this embodiment, since the number of optical cables that need to be coiled on the fiber coiling part 3 may be large, if only one fiber guiding port is provided on the first disk surface 1 and the second disk surface 2, then all the optical cables can only be led out from this fiber guiding port and docked at a position near this fiber guiding port, which will cause the optical cables on the disk surface to be concentrated near this fiber guiding port, resulting in very messy optical cables on the disk surface; therefore, in this embodiment, multiple fiber guiding ports are provided on both the first disk surface 1 and the second disk surface 2; the first preset number can be 2 - 4, the number of the first fiber guiding ports 11 on the first disk surface 1 is the same as the number of the second fiber guiding ports 21 on the second disk surface 2, and the distribution of the first fiber guiding ports 11 on the first disk surface 1 is the same as the distribution of the second fiber guiding ports 21 on the second disk surface 2. If too many fiber guiding ports are provided on the first disk surface 1 and the second disk surface 2, it may cause the structural strength of the first disk surface 1 and the second disk surface 2 to be too low, so the number of fiber guiding ports that can be provided on the first disk surface 1 or the second disk surface 2 does not exceed 4.

[0061] In this embodiment, on the one hand, the optical cable reel with multiple lateral slots is used for coiling multiple optical cables, and on the other hand, it is also necessary to ensure that all the optical cables on the optical cable reel are in a state where they are docked with each other. When the optical cables of the optical cable reel need to be used, the optical cables can be unloaded from the optical cable reel and directly used, without the need to dock each section of the optical cable at the application site, which can greatly improve the efficiency of the actual application of the optical cable; therefore, in this embodiment, the head or tail end of each section of the optical cable on the fiber coiling part 3 is led out through the first fiber guiding port 11 and the second fiber guiding port 21, and the head and tail ends of different optical fibers are docked outside the first disk surface 1 or the second disk surface 2, so as to connect the head and tail of all the optical cables on the fiber coiling part 3 in sequence and form an optical cable with a specified length.

[0062] For ease of understanding, the following example is used for demonstration: Fiber optic cables a, b, and c are all coiled on the fiber optic coiling part 3. The three fiber optic cables need to be connected in sequence according to the order of fiber optic cables a, b, and c. Fiber optic cables a, b, and c are all coiled on the fiber optic coiling part 3. The head end of fiber optic cable a is led out from the first fiber guiding port 11, and the tail end of fiber optic cable a is led out from the second fiber guiding port 21. The head end of fiber optic cable b is led out from the second fiber guiding port 21. The tail end of fiber optic cable a and the head end of fiber optic cable b are butted outside the second disk surface 2. The tail end of fiber optic cable b is led out from the first fiber guiding port 11. The head end of fiber optic cable c is led out from the first fiber guiding port 11. The tail end of fiber optic cable b and the head end of fiber optic cable c are butted outside the first disk surface 1. The tail end of fiber optic cable c is led out from the second fiber guiding port 21, completing the sequential connection of fiber optic cables a, b, and c.

[0063] It should be noted that in this embodiment, each fiber optic cable includes multiple fiber cores. The butt joint between different fiber optic cables refers to the corresponding interconnection of the fiber cores in different fiber optic cables. Multiple fiber cores in one fiber optic cable are connected one-to-one with the same number of multiple fiber cores in another fiber optic cable, enabling optical path connection between different fiber optic cables.

[0064] In this embodiment, in order to ensure that the butt joint positions of each fiber optic cable can be evenly distributed on the first disk surface 1 or the second disk surface 2, thereby avoiding the messy placement of fiber optic cables on the first disk surface 1 or the second disk surface 2, it is necessary to ensure that the lead-out positions of all fiber optic cables on the first disk surface 1 or the second disk surface 2 are evenly distributed. Therefore, this embodiment involves the following design:

[0065] As Figure 1 and Figure 2 shown, the included angles between the connections of the centers of every two adjacent first fiber guiding ports 11 and the first disk surface 1 are all equal; the included angles between the connections of the centers of every two adjacent second fiber guiding ports 21 and the second disk surface 2 are all equal.

[0066] In this embodiment, all the first fiber guiding ports 11 on the first disk surface 1 are evenly distributed around the center of the first disk surface 1, and the included angles between the connections of the centers of two adjacent first fiber guiding ports 11 on the first disk surface 1 and the center of the first disk surface 1 are all the same. All the second fiber guiding ports 21 on the second disk surface 2 are evenly distributed around the center of the second disk surface 2, and the included angles between the connections of the centers of two adjacent second fiber guiding ports 21 on the second disk surface 2 and the center of the second disk surface 2 are all the same.

[0067] In this embodiment, when the optical cable is led out from the first fiber guiding port 11 to the side of the first disk surface 1 or from the second fiber guiding port 21 to the side of the second disk surface 2, the optical cable needs to be bent correspondingly at the first fiber guiding port 11 or the second fiber guiding port 21, and the bending path needs to pass through the notch edge of the first fiber guiding port 11 or the second fiber guiding port 21. To avoid damage to the optical cable caused by the sharp corner at the notch edge of the first fiber guiding port 11 or the second fiber guiding port 21, the following design is involved in this embodiment: As Figure 3 and Figure 4 shown, a first transition slope 12 is provided on the side where the first fiber guiding port 11 leads to the outside of the first disk surface 1. The first transition slope 12 is arranged around the circumferential side of the first fiber guiding port 11. The upper end of the first transition slope 12 extends to the outer side surface of the first disk surface 1, and the lower end of the first transition slope 12 extends to the first fiber guiding port 11. A second transition slope 22 is provided on the side where the second fiber guiding port 21 leads to the outside of the second disk surface 2. The second transition slope 22 is arranged around the circumferential side of the second fiber guiding port 21. The upper end of the second transition slope 22 extends to the outer side surface of the second disk surface 2, and the lower end of the second transition slope 22 extends to the second fiber guiding port 21.

[0068] In this embodiment, in the actual application scenario, when the optical cable needs to be removed from the optical cable reel, the common method is mostly to fix the axis of the optical cable reel and let the optical cable reel rotate around the axis position. While rotating, the optical cable is removed in the fiber coiling direction. Therefore, in order to facilitate the removal of the optical cable from the optical cable reel in this embodiment, the following design is also involved: As Figure 4 shown, the optical cable reel with multi-grooves on both sides also includes a rotating hole 4, and the rotating hole 4 penetrates through the first disk surface 1, the fiber coiling part 3, and the second disk surface 2 in sequence.

[0069] In this embodiment, the rotating hole 4 is located at the central positions of the first disk surface 1, the second disk surface 2, and the fiber coiling part 3, and is used to insert a rotating shaft into the rotating hole 4 when the optical cable needs to be removed later, so that the optical cable reel rotates around the rotating shaft while the optical cable is removed.

[0070] In this embodiment, in order to separate the optical cable inside the optical cable reel from the outside, the following design is also involved in this embodiment: As Figure 5 shown, the optical cable reel with multi-grooves on both sides also includes a protective shell 5, where: the protective shell 5 is arranged around the circumferences of the first disk surface 1 and the second disk surface 2. One end of the protective shell 5 is connected to the circumferential side of the first disk surface 1, and the other end of the protective shell 5 is connected to the circumferential side of the second disk surface 2.

[0071] In this embodiment, since the optical cables stored in the optical cable reel need to be butt-jointed in sequence, and the butt-joint positions of the respective optical cables are located outside the first disk surface 1 or the second disk surface 2, the following design is involved for the 6 butt-joint connectors between the optical cables in this embodiment: As Figure 5 and Figure 6 shown, a second preset number of butt-joint connectors 6 are detachably provided on the first disk surface 1, and a third preset number of butt-joint connectors 6 are detachably provided on the second disk surface 2; the butt-joint connectors 6 provided on the first disk surface 1 are used to butt-joint two optical cables led out from different first fiber leading-out ports 11; the butt-joint connectors 6 provided on the second disk surface 2 are used to butt-joint two optical cables led out from different second fiber leading-out ports 21.

[0072] In this embodiment, both the second preset number and the third preset number are set by those skilled in the art according to the number of optical cables, that is, the butt-joint number of optical cables on the first disk surface 1 is the second preset number, and the butt-joint number of optical cables on the second disk surface 2 is the third preset number. In this embodiment, since the butt-joint connector 6 itself has a certain weight, the butt-joint connector 6 will pull on the optical cable due to its own gravity, which may cause damage to the optical cable and affect the stability of the butt-joint part of the optical cable. Therefore, it is necessary to fix the butt-joint connector 6 on the first disk surface 1 or the second disk surface 2 to prevent the butt-joint connector 6 from pulling on the optical cable and damaging the optical cable. However, since the butt-joint connector 6 needs to be removed from the first disk surface 1 or the second disk surface 2 synchronously when the stored optical cable needs to be removed, in this embodiment, the butt-joint connector 6 is detachably installed on the first disk surface 1 or the second disk surface 2, which is convenient for fixing the butt-joint connector 6 on the first disk surface 1 or the second disk surface 2 when transporting the optical cable reel, and at the same time is convenient for detaching the butt-joint connector 6 from the first disk surface 1 or the second disk surface 2 when the optical cable needs to be removed, that is, the said detachable setting; in this embodiment, the detachable setting can be realized by the cooperation of screws and corresponding screw holes.

[0073] Since the butt-joint connector 6 needs to be connected to two optical cables at the same time and needs to provide corresponding space for the butt-joint between the cores of the two optical cables, the following design is also involved in this embodiment: As Figure 7 and Figure 8As shown in the figure, the docking device 6 specifically includes: a housing box body 61, a first docking port 611, a second docking port 612, and a tensile member 65, where: the first docking port 611 is disposed on one side of the housing box body 61, and the first docking port 611 communicates the outside and the inside of the housing box body 61; the first docking port 611 is used to connect to a first optical cable, and the fiber core and the reinforcing rib 7 in the first optical cable are introduced into the housing box body 61 through the first docking port 611; the second docking port 612 is disposed on the other side of the housing box body 61, and the second docking port 612 communicates the outside and the inside of the housing box body 61; the second docking port 612 is used to connect to a second optical cable, and the fiber core and the reinforcing rib 7 in the second optical cable are introduced into the housing box body 61 through the second docking port 612; the inside of the housing box body 61 is used for coiling and docking the fiber cores of the first optical cable and the second optical cable; the tensile member 65 is respectively connected to the reinforcing rib 7 of the first optical cable and the reinforcing rib 7 of the second optical cable; wherein, the first optical cable and the second optical cable are any two different optical cables.

[0074] In this embodiment, the first optical cable and the second optical cable may refer to any two adjacent connected optical cables stored on the fiber coiling part 3.

[0075] In the existing optical cable design, in order to ensure that the optical cable has a certain toughness during actual use and storage, and will not cause damage to the internal fiber core due to bending, one or more reinforcing ribs 7 with a certain toughness are provided in the optical cable. The reinforcing rib 7 can be made of metal to ensure that the optical cable itself has a certain toughness. In this embodiment, in order to ensure the stability when two optical cables are docked through the docking device 6, the reinforcing ribs 7 in the two optical cables are led out in the docking device 6 and are respectively connected to the two reinforcing ribs 7 through the tensile member 65, so that in addition to being docked through the docking device 6, the two optical cables are also connected through the respective reinforcing ribs 7 and the tensile member 65 of the two optical cables, greatly enhancing the docking strength and stability between the optical cables.

[0076] In addition, it is worth mentioning that, as Figure 8 shown, if there are at least two reinforcing ribs 7 in a single optical cable, the docking device 6 includes at least two tensile members 65; one tensile member 65 is used to connect to one of the reinforcing ribs 7 of the first optical cable and one of the reinforcing ribs 7 of the second optical cable respectively, and the other tensile member 65 is used to connect to the other reinforcing rib 7 of the first optical cable and the other reinforcing rib 7 of the second optical cable respectively. Through the connection of the two tensile members 65, the docking strength is further enhanced.

[0077] In this embodiment, the following design is involved for the tensile member 65: as Figure 9As shown, the tensile member 65 specifically includes: a base 651, a first screw 6522, a second screw 6532, a first nut 654, and a second nut 655, where:

[0078] The first screw 6522 and the second screw 6532 are arranged on the base 651.

[0079] The first screw 6522 is used for the reinforcing rib 7 of the first optical cable to wind around. The first nut 654 is sleeved on the first screw 6522. The first nut 654 is located above the reinforcing rib 7 wound on the first screw 6522. The first nut 654 is used to limit the reinforcing rib 7 wound on the first screw 6522.

[0080] The second screw 6532 is used for the reinforcing rib 7 of the second optical cable to wind around. The second nut 655 is sleeved on the second screw 6532. The second nut 655 is located above the reinforcing rib 7 wound on the second screw 6532. The second nut 655 is used to limit the reinforcing rib 7 wound on the second screw 6532.

[0081] In this embodiment, to further ensure the stability of the winding and fixing of the two reinforcing ribs 7 on the screw, the following design is also involved in this embodiment: As Figure 10 and Figure 11 shown, the tensile member 65 further includes: a limiting plate 656, where: a third through hole 6561 and a fourth through hole 6562 are provided on the limiting plate 656; the third through hole 6561 is sleeved on the first screw 6522, and the fourth through hole 6562 is sleeved on the second screw 6532; the limiting plate 656 is located between the first nut 654 and the reinforcing rib 7 wound on the first screw 6522, and the limiting plate 656 is also located between the second nut 655 and the reinforcing rib 7 wound on the second screw 6532; the limiting plate 656 is used to limit the reinforcing rib 7 wound on the first screw 6522 and the reinforcing rib 7 wound on the second screw 6532.

[0082] In this embodiment, the installation method of the tensile member 65 is as follows: Wind and fix the strengthening ribs 7 of two optical cables around the outer perimeters of the first screw rod 6522 and the second screw rod 6532 respectively. Insert the limit plate 656 downward from the upper position of the base 651, and sleeve the third through hole 6561 and the fourth through hole 6562 around the outer perimeters of the first screw rod 6522 and the second screw rod 6532 respectively. At this time, the limit plate 656 is above the strengthening ribs 7 wound around the outer perimeters of the first screw rod 6522 and the second screw rod 6532. Then, sleeve the first nut 654 and the second nut 655 around the outer perimeters of the first screw rod 6522 and the second screw rod 6532 respectively, and through the cooperation of the first nut 654 and the second nut 655 with the first screw rod 6522 and the second screw rod 6532 respectively, press the first nut 654 and the second nut 655 above the limit plate 656 respectively, so that the strengthening ribs 7 wound around the outer perimeters of the first screw rod 6522 and the second screw rod 6532 are stably pressed and fixed by the limit plate 656; the stability of the tensile member 65 is improved.

[0083] On the other hand, when actually docking two optical cables, a part of the optical fibers in the two optical cables need to be led out and docked. Therefore, the docking device 6 also needs to be provided with a corresponding storage box for storing the optical fibers led out from the two docked optical cables to avoid the chaotic placement of the optical fibers in the docking device 6. Therefore, this embodiment also involves the following settings: As Figure 12 shown, the docking device 6 further includes a fiber coiling box 64, and the fiber coiling box 64 is arranged in the outer shell box body 61; one end of the fiber coiling box 64 facing the first docking port 611 is provided with a first input port 641, and the first input port 641 is used to introduce the optical fibers of the first optical cable introduced from the first docking port 611 into the interior of the fiber coiling box 64; one end of the fiber coiling box 64 facing the second docking port 612 is provided with a second input port 642, and the second input port 642 is used to introduce the optical fibers of the second optical cable introduced from the second docking port 612 into the interior of the fiber coiling box 64. The interior of the fiber coiling box 64 is used for coiling and docking the optical fibers of the first optical cable and the optical fibers of the second optical cable.

[0084] In this embodiment, the optical fibers of the first optical cable and the second optical cable are arranged in a multi-turn coiling in the fiber coiling box 64 and are docked at a specified position in the multi-turn coiling. In this embodiment, the fiber coiling box 64 can also be provided with corresponding limiting platforms for limiting the optical fibers in the fiber coiling box 64 to make the optical fibers coil and be stored according to a predetermined track.

[0085] On the other hand, considering that after butt-jointing each section of optical cable and using it in an actual application scenario, it is necessary to monitor the positions of each section of the butt-jointed optical cable to detect the real-time status of the optical cable and the environment of the application scenario. Mostly, corresponding sensors are connected to the fiber cores in the optical cable, and the transmission status of the optical signals in the fiber cores is detected for monitoring, so as to obtain the index parameters of the optical cable or the actual application scenario. Therefore, this embodiment also involves the following design: As Figure 12 shown, a sensor docking port 613 is further provided on the outer shell box body 61. The sensor docking port 613 is used to dock with an external sensor, and the external sensor is used to connect to the fiber core of the first optical cable or the second optical cable in the outer shell box body 61. A first output port 643 is further provided on the fiber optic splice tray 64. The first output port 643 is used for the fiber core of the first optical cable or the second optical cable in the fiber optic splice tray 64 to be led out of the fiber optic splice tray 64 and connected to the external sensor through the sensor docking port 613.

[0086] In this embodiment, since the sensor needs to be connected to at least one fiber core to detect the corresponding parameters of the optical signals in the optical cable, when every two optical cables are butt-jointed, at least one fiber core needs to be separated from the first optical cable and the second optical cable for being led out from the first output port 643 and docked with the external sensor through the sensor docking port 613. Therefore, in this embodiment, when every two optical cables are butt-jointed, at least one fiber core needs to be led out for docking with the sensor. As the optical cables are butt-jointed in sequence, at least one fiber core is fixedly led out and docked with the sensor each time of docking. The number of fiber cores for butt-jointing between subsequent optical cables decreases in sequence. Therefore, it is necessary to set the number of fiber cores in the optical cable according to the total number of optical cables required to ensure that sensors are provided at each docking position and there are enough fiber cores for butt-jointing between optical cables at all docking positions.

[0087] To illustrate the above design more clearly, the following example is given: In an actual application scenario, 5 optical cables need to be butt-jointed in sequence for operation. One fiber core is required at each docking position for docking with the sensor, and each fiber core is provided with 6 fiber cores. When the first optical cable and the second optical cable are butt-jointed, 5 fiber cores in the first optical cable and the second optical cable are correspondingly connected, and one fiber core is connected to the sensor. When the second optical cable and the third optical cable are butt-jointed, 4 fiber cores in the second optical cable and the third optical cable are correspondingly connected, and one fiber core is connected to the sensor. When the third optical cable and the fourth optical cable are butt-jointed, 3 fiber cores in the third optical cable and the fourth optical cable are correspondingly connected, and one fiber core is connected to the sensor. When the fourth optical cable and the fifth optical cable are butt-jointed, 2 fiber cores in the fourth optical cable and the fifth optical cable are correspondingly connected, and one fiber core is connected to the sensor.

[0088] It is worth mentioning that, in order to prevent failures in individual optical fibers in the optical cable, a certain number of optical fibers can be reserved in the optical cable without being connected between the optical cables temporarily and without being used for docking with the sensor temporarily, and they are only used as spare optical fibers when some working optical fibers fail.

[0089] In this embodiment, in order to ensure the detachable setting of the docking device 6 relative to the first disk surface 1 and the second disk surface 2, a preferred setting is provided as follows: As Figure 13 and Figure 14 shown, a plurality of screw hole platforms 63 are further provided on the outer side of the outer shell box body 61, and a first screw hole 631 is provided on each screw hole platform 63. Second screw holes 8 are provided at corresponding positions on the first disk surface 1 and the second disk surface 2. The second screw holes 8 are used to correspond to the positions of the first screw holes 631, and the docking device 6 is fixed on the first disk surface 1 or the second disk surface 2 through screws.

[0090] In this embodiment, the docking device 6 needs to be arranged on the periphery of the through hole 4 of the first disk surface 1 and the second disk surface 2. Therefore, the second screw holes 8 corresponding to the first screw holes 631 are located on the periphery of the through hole 4 of the first disk surface 1 and the second disk surface 2. In this embodiment, the outer shell box body 61 is in a cuboid shape, and four screw hole platforms 63 are provided on the four side surfaces of the outer shell box body 61. Corresponding to this, every four second screw holes 8 on the first disk surface 1 and the second disk surface 2 are in a group, and are used to cooperate with the first screw holes 631 on the screw hole platforms 63 of the corresponding outer shell box body 61 through screws. Each group of second screw holes 8 is arranged on the periphery of the through hole 4 and is located between two adjacent first fiber guiding ports 11 or two adjacent second fiber guiding ports 21.

[0091] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
