Description

Technical Field

[0002] In the existing optical cable applications, it is usually necessary to transport multiple optical cables to the corresponding application scenarios, connect each optical cable in a predetermined order in the application scenarios, and install and deploy them in the corresponding application scenarios. When storing multiple optical cables, they are coiled in the corresponding reels. If you want to connect each optical cable in the preset connection order, you need to remove each optical cable from the reel one by one to complete the connection work. When the optical cables are coiled in the reel, it is impossible to connect each optical cable, resulting in great limitations and low efficiency in optical cable-related operations.

[0055] 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.

[0056] Embodiment 1:

[0057] Embodiment 1 of the present utility model provides a fiber optic cable reel system with multiple slots on both sides, as Figure 1 shown, including: multiple fiber optic cables, a docking connector 6, and a fiber optic cable reel 9, where: each of the fiber optic cables is coiled in the fiber optic cable reel 9, multiple first fiber guiding ports 11 are provided on one side of the fiber optic cable reel 9, multiple second fiber guiding ports 21 are provided on the other side of the fiber optic cable reel 9, and both ends of each fiber optic cable are respectively led out from the first fiber guiding port 11 and the second fiber guiding port 21 to both sides of the fiber optic cable reel 9; all the fiber optic cables are connected in sequence on both sides of the fiber optic cable reel 9 according to a preset connection sequence, and each adjacent two fiber optic cables in the preset connection sequence are connected through the docking connector 6.

[0058] In this embodiment, the optical cable reel 9 is used for winding and storing multiple optical cables. Both ends of each optical cable stored in the optical cable reel 9 can be led out through the first optical fiber leading port 11 and the second optical fiber leading port 21 respectively. After being led out, the optical cables can be connected end to end in sequence according to the specified order. The optical cables can be connected through the connector 6, so as to complete the connection of the optical cables in the state of winding and storing the optical fibers, avoiding the need to take out the optical cables one by one from the storage device and perform on-site connection in the actual application scenario of the optical cables. In this embodiment, all the optical cables can also complete the corresponding connection in the state of being stored in the optical cable reel 9. Therefore, after transporting the optical cable reel 9 storing the optical cables to the application scenario, the connected optical cables can be directly unloaded from the optical cable reel 9 and the optical cables can be deployed and installed, without the need to connect each optical cable at the application work site, greatly improving the efficiency of the actual application of the optical cables and the efficiency of installation and deployment.

[0059] As Figure 1 shown, a sensor interface 613 is further provided on each connector 6. The sensor interface 613 is used to connect with an external sensor, and at least one optical fiber core led out from two optical cables connected by the connector 6 is connected to the external sensor.

[0060] When the optical cable segments are connected and used in the actual application scenario, it is necessary to monitor the positions of the connected optical cable segments to detect the real-time status of the optical cables and the environment of the application scenario. Therefore, in this embodiment, in addition to being used to connect two optical cables, the connector 6 is also provided with an additional sensor interface 613 for connecting with an external sensor. The external sensor monitors by detecting the transmission state of the optical signal in the optical fiber core, so as to obtain the index parameters of the optical cable or the actual application scenario. By monitoring the connection positions of every two optical cables through an external sensor, the status of each position of the entire connected optical cable can be understood.

[0061] As Figure 1 and Figure 2 shown, the optical cable reel 9 includes: a first disk surface 1, a second disk surface 2 and a fiber winding part 3, wherein: the first disk surface 1 is arranged on one side of the fiber winding part 3, and the second disk surface 2 is arranged on the other side of the fiber winding part 3.

[0062] In this embodiment, both the first disk surface 1 and the second disk surface 2 are circular, the fiber winding part 3 is cylindrical, one end face of the fiber winding part 3 is connected to the center position of the first disk surface 1, and the other end face of the fiber winding part 3 is connected to the center position of the second disk surface 2; the axes of the first disk surface 1, the fiber winding part 3 and the second disk surface 2 are the same; the sizes of the first disk surface 1 and the second disk surface 2 are the same.

[0063] AsFigure 1 and Figure 2 As shown in Figure 2 , a plurality of first fiber guiding ports 11 are arranged on the peripheral side of the first disk surface 1. One side of the first fiber guiding port 11 leads to the inner side of the first disk surface 1, and the other side leads to the outer side of the first disk surface 1; a plurality of second fiber guiding ports 21 are arranged on the peripheral side of the second disk surface 2. One side of the second fiber guiding port 21 leads to the inner side of the second disk surface 2, and the other side leads to the outer side of the second disk surface 2.

[0064] As Figure 1 and Figure 2 shown, where Figure 2 is another optical cable reel 9 with different numbers of fiber outlet ports, Figure 1 and Figure 2 show the situation when the optical cable is stored on the optical cable reel 9, and Figure 1 and Figure 2 a protective shell is arranged on the peripheral side of the optical cable reel 9 in Figure 2 . 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 leading the optical cable from the fiber coiling part 3 to the outer side of the first disk surface 1 and docking with other optical cables; the second fiber guiding port 21 is used for leading the optical cable from the fiber coiling part 3 to the outer side of the second disk surface 2 and docking with other optical cables.

[0065] In this embodiment, the first fiber guiding port 11 is arranged on the side wall of the peripheral 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 peripheral side of the second disk surface 2 and extends towards the center of the second disk surface 2.

[0066] In this embodiment, since the number of optical cables to be coiled on the fiber coiling part 3 may be large, if only one fiber guiding port is arranged 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 the optical cables on the disk surface being very messy; therefore, in this embodiment, a plurality of fiber guiding ports are arranged on both the first disk surface 1 and the second disk surface 2. The number of the first fiber outlet ports 11 on the first disk surface 1 and the number of the second fiber outlet ports 21 on the second disk surface 2 can be the same, and both can be 2 - 4.

[0067] 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 arranged 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. Therefore, the number of fiber guiding ports that can be arranged on the first disk surface 1 or the second disk surface 2 does not exceed 4.

[0068] In this embodiment, on the one hand, the optical cable reel is used for coiling multiple optical cables. On the other hand, it is necessary to ensure that all the optical cables coiled on the optical cable reel 9 are in a butted state with each other. When the optical cables of the optical cable reel 9 are needed, the optical cables can be unloaded from the optical cable reel 9 and directly used without butt-jointing 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 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 butted outside the first disk surface 1 or the second disk surface 2, so that all the optical cables on the coiling part 3 are butted end to end in sequence and connected into an optical cable of a specified length.

[0069] For easy understanding, the following example is used for demonstration: The a optical cable, the b optical cable, and the c optical cable are all coiled on the coiling part 3. It is necessary to connect the three optical cables in sequence according to the order of the a optical cable, the b optical cable, and the c optical cable. The a optical cable, the b optical cable, and the c optical cable are all coiled on the coiling part 3. The head end of the a optical cable is led out from the first fiber guiding port 11, and the tail end of the a optical cable is led out from the second fiber guiding port 21. The head end of the b optical cable is led out from the second fiber guiding port 21. The tail end of the a optical cable and the head end of the b optical cable are butted outside the second disk surface 2. The tail end of the b optical cable is led out from the first fiber guiding port 11. The head end of the c optical cable is led out from the first fiber guiding port 11. The tail end of the b optical cable and the head end of the c optical cable are butted outside the first disk surface 1. The tail end of the c optical cable is led out from the second fiber guiding port 21, completing the sequential connection of the a optical cable, the b optical cable, and the c optical cable.

[0070] It should be noted that in this embodiment, each optical cable includes multiple fiber cores. The butt-jointing between different optical cables refers to the corresponding interconnection of the fiber cores in different optical cables. The multiple fiber cores in one optical cable are connected to the same number of multiple fiber cores in another optical cable one by one, so that the optical paths between different optical cables are connected.

[0071] In this embodiment, in order to ensure that the butt-jointing positions of all optical cables can be evenly distributed on the first disk surface 1 or the second disk surface 2, so as to avoid the disorderly placement of optical cables on the first disk surface 1 or the second disk surface 2, it is necessary to ensure that the leading-out positions of all optical cables on the first disk surface 1 or the second disk surface 2 are evenly distributed. Therefore, this embodiment involves the following design:

[0072] The included angles between the center lines connecting every two adjacent first fiber guiding ports 11 and the center of the first disk surface 1 are all equal; the included angles between the center lines connecting every two adjacent second fiber guiding ports 21 and the center of the second disk surface 2 are all equal.

[0073] In this embodiment, all the first fiber guiding openings 11 on the first disk surface 1 are evenly distributed around the center of the first disk surface 1, and the angles between the connecting lines of two adjacent first fiber guiding openings 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 openings 21 on the second disk surface 2 are evenly distributed around the center of the second disk surface 2, and the angles between the connecting lines of two adjacent second fiber guiding openings 21 on the second disk surface 2 and the center of the second disk surface 2 are all the same.

[0074] In this embodiment, when the optical cable is led out from the first fiber guiding opening 11 to the side surface of the first disk surface 1 or from the second fiber guiding opening 21 to the side surface of the second disk surface 2, the optical cable needs to be bent correspondingly at the first fiber guiding opening 11 or the second fiber guiding opening 21, and the bending path needs to pass through the notch edge of the first fiber guiding opening 11 or the second fiber guiding opening 21. In order to avoid damage to the optical cable caused by the sharp corner at the notch edge of the first fiber guiding opening 11 or the second fiber guiding opening 21, the following design is involved in this embodiment: As Figure 3 and Figure 4 shown, a first transition inclined surface 12 is provided on the side of the first fiber guiding opening 11 leading to the outside of the first disk surface 1. The first transition inclined surface 12 is arranged around the circumferential side of the first fiber guiding opening 11. The upper end of the first transition inclined surface 12 extends to the outer side surface of the first disk surface 1, and the lower end of the first transition inclined surface 12 extends to the first fiber guiding opening 11. A second transition inclined surface 22 is provided on the side of the second fiber guiding opening 21 leading to the outside of the second disk surface 2. The second transition inclined surface 22 is arranged around the circumferential side of the second fiber guiding opening 21. The upper end of the second transition inclined surface 22 extends to the outer side surface of the second disk surface 2, and the lower end of the second transition inclined surface 22 extends to the second fiber guiding opening 21.

[0075] In this embodiment, in the actual application scenario, when it is necessary to remove the optical cable from the optical cable reel 9, the common method is mostly to fix the axis of the optical cable reel 9 and let the optical cable reel 9 rotate around the axis position, and remove the optical cable in the fiber coiling direction while rotating. Therefore, in order to facilitate the removal of the optical cable from the optical cable reel 9 in this embodiment, the following design is also involved: As Figure 4 shown, the optical cable reel 9 further includes a rotating hole 4. The rotating hole 4 is located at the central axis position of the first disk surface 1, the fiber coiling part 3 and the second disk surface 2, and penetrates through the first disk surface 1, the fiber coiling part 3 and the second disk surface 2 in sequence.

[0076] 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 for inserting a rotating shaft into the rotating hole 4 when the optical cable needs to be removed subsequently, so that the optical cable reel 9 rotates around the rotating shaft, and the optical cable is removed at the same time.

[0077] In this embodiment, in order to separate the optical cables inside the optical cable reel 9 from the outside, the following designs are also involved in this embodiment: Figure 5 As shown, the optical cable reel 9 also includes a protective outer shell 5, wherein: the protective outer shell 5 is arranged around the circumference of the first reel surface 1 and the circumference of the second reel surface 2, one end of the protective outer shell 5 is connected to the circumferential side of the first reel surface 1, and the other end of the protective outer shell 5 is connected to the circumferential side of the second reel surface 2.

[0078] In this embodiment, the docking device also involves the following designs: Figure 5 and Figure 6 As shown, a second preset number of docking connectors 6 are detachably provided on the first disk surface 1, and a third preset number of docking connectors 6 are detachably provided on the second disk surface 2; the docking connectors 6 arranged on the first disk surface 1 are used to connect two optical cables led out from different first fiber lead-in ports 11; the docking connectors 6 arranged on the second disk surface 2 are used to connect two optical cables led out from different second fiber lead-in ports 21.

[0079] In this embodiment, the second preset number and the third preset number are both set by technicians in this field according to the number of optical cables, that is, the number of optical cables connected on the first disk surface 1 is the second preset number, and the number of optical cables connected on the second disk surface 2 is the third preset number. In this embodiment, since the docking device 6 itself has a certain weight, the docking device 6 will pull the optical cable due to its own gravity, which may cause damage to the optical cable and affect the stability of the docking part of the optical cable. Therefore, the docking device 6 needs to be fixed on the first disk surface 1 or the second disk surface 2 to prevent the docking device 6 from pulling the optical cable and damaging the optical cable. However, when the stored optical cable needs to be removed, the docking device 6 needs to be removed from the first disk surface 1 or the second disk surface 2 at the same time. Therefore, in this embodiment, the docking device 6 is detachably installed on the first disk surface 1 or the second disk surface 2, which is convenient for fixing the docking device 6 on the first disk surface 1 or the second disk surface 2 when transporting the optical cable disk, and at the same time, it is convenient to remove the docking device 6 from the first disk surface 1 or the second disk surface 2 when the optical cable needs to be removed, that is, the detachable setting; in this embodiment, the detachable setting can be achieved by the cooperation of screws and corresponding screw holes.

[0080] Since the butt joint 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 fiber cores of the two optical cables, this embodiment also involves the following designs: 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, and a second docking port 612, where: the first docking port 611 is arranged 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 optical fiber core in the first optical cable is introduced into the housing box body 61 through the first docking port 611; the second docking port 612 is arranged 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 optical fiber core in the second optical cable is 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 optical fiber cores of the first optical cable and the second optical cable; where the first optical cable and the second optical cable are any two optical cables led out from different first optical fiber leading ports 11 or different second optical fiber leading ports 21.

[0081] In this embodiment, the first optical cable and the second optical cable can refer to any two adjacent and sequentially connected optical cables stored on the optical fiber coiling part 3.

[0082] 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 optical fiber core due to bending, one or more reinforcing ribs 7 with a certain toughness are provided in the optical cable. The reinforcing ribs 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 of the two optical cables when they 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.

[0083] In this embodiment, as Figure 7 shown, the sensor docking port 613 is arranged on the housing box body 61, and the sensor docking port 613 is used to dock with an external sensor, and the external sensor is used to connect to the optical fiber core of the first optical cable or the second optical cable in the housing box body 61.

[0084] In this embodiment, since the sensor needs to be connected to at least one optical fiber core to detect the corresponding parameters of the optical signal in the optical cable, when every two optical cables are butt-jointed, at least one optical fiber core needs to be separated from the first optical cable and the second optical cable for leading out from the first output port 643, and is butt-jointed with an external sensor through the sensor butt-joint port 613. Therefore, in this embodiment, when every two optical cables are butt-jointed, at least one optical fiber core needs to be led out for butt-jointing with the sensor. As the optical cables are butt-jointed in sequence, at least one optical fiber core is fixedly led out for butt-jointing with the sensor each time of butt-jointing, and the number of optical fiber cores for butt-jointing between subsequent optical cables decreases in sequence. Therefore, it is necessary to set the number of optical fiber cores in the optical cable according to the total number of optical cables required, so as to ensure that sensors are arranged at each butt-joint position and there are enough optical fiber cores at all butt-joint positions for butt-jointing between optical cables.

[0085] 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 optical fiber core is required at each butt-joint position for butt-jointing with the sensor, and each optical fiber core is provided with 6 optical fiber cores. When the first optical cable and the second optical cable are butt-jointed, the 5 optical fiber cores in the first optical cable and the second optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the second optical cable and the third optical cable are butt-jointed, the 4 optical fiber cores in the second optical cable and the third optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the third optical cable and the fourth optical cable are butt-jointed, the 3 optical fiber cores in the third optical cable and the fourth optical cable are correspondingly connected, and one optical fiber core is connected to the sensor. When the fourth optical cable and the fifth optical cable are butt-jointed, the 2 optical fiber cores in the fourth optical cable and the fifth optical cable are correspondingly connected, and one optical fiber core is connected to the sensor.

[0086] It is worth mentioning that in order to prevent individual optical fiber cores in the optical cable from failing, a certain number of optical fiber cores can be reserved in the optical cable and not be connected between optical cables temporarily, nor be used for butt-jointing with the sensor temporarily, but only be used as spare optical fiber cores when some working optical fiber cores fail.

[0087] 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 butt-joint device 6 includes at least two tensile members 65. One tensile member 65 is used to be connected 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 be connected 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 butt-joint strength is further enhanced.

[0088] 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:

[0089] The first screw 6522 and the second screw 6532 are arranged on the base 651.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] In this embodiment, the installation method of the tensile member 65 is as follows: Wind and fix the reinforcing ribs 7 of two optical cables around the outer perimeters of the first screw 6522 and the second screw 6532 respectively. Insert the limit plate 656 downward from the upper position of the base 651, and sleeved the third through hole 6561 and the fourth through hole 6562 around the outer perimeters of the first screw 6522 and the second screw 6532 respectively. At this time, the limit plate 656 is above the reinforcing ribs 7 wound around the outer perimeters of the first screw 6522 and the second screw 6532. Then, sleeve the first nut 654 and the second nut 655 around the outer perimeters of the first screw 6522 and the second screw 6532 respectively, and through the cooperation of the first nut 654 and the second nut 655 with the first screw 6522 and the second screw 6532 respectively, press the first nut 654 and the second nut 655 above the limit plate 656 respectively, so that the reinforcing ribs 7 wound around the outer perimeters of the first screw 6522 and the second screw 6532 are stably pressed and fixed by the limit plate 656; the stability of the tensile member 65 is improved.

[0094] On the other hand, since when actually docking two optical cables, a part of the cores in the two optical cables need to be led out and docked, a corresponding storage box needs to be provided in the docking device 6 to store the cores led out from the two docked optical cables, to avoid the chaotic placement of the cores 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 core 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 core 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 cores of the first optical cable and the second optical cable.

[0095] The fiber coiling box 64 is further provided with a first output port 643, and the first output port 643 is used to allow the core of the first optical cable or the core of the second optical cable in the fiber coiling box 64 to be led out from the fiber coiling box 64 and connected to an external sensor through the sensor docking port 613.

[0096] In this embodiment, the cores of the first optical cable and the second optical cable are set for multi-turn fiber coiling in the fiber coiling box 64 and are docked at a specified position in the multi-turn fiber coiling. In this embodiment, corresponding limit platforms can also be provided in the fiber coiling box 64 to limit the cores in the fiber coiling box 64 and make the cores coil and store according to a predetermined trajectory.

[0097] 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. 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 by screws.

[0098] 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.
