Description

Technical Field

[0001] This utility model belongs to the field of drone accessories, and specifically relates to a fiber optic roll storage bin for use in drones. Background Technology

[0002] With the continuous development of drone technology, its application scenarios are becoming increasingly widespread. As a bridge connecting drones and ground control stations, drone communication modules play a crucial role. Fiber optic communication, due to its significant advantages such as large transmission bandwidth and strong anti-interference capabilities, is very suitable for long-distance data transmission or high-precision operations, and is also used in drone communication.

[0003] Existing drones typically use fiber optic cables in the form of fiber optic canisters for operation. During use, the fiber optic canister is fixed in a designated position on the drone's fuselage, ensuring that the cable laying direction matches the flight direction to avoid interference with the rotor and arms. The fiber optic canister contains a fiber optic roll and a fiber optic module. One end of the fiber optic roll connects to a ground-based optical transceiver via a fiber optic connector, which in turn connects to the ground control terminal. The other end connects to the fiber optic module, which in turn connects to the drone's onboard optical transceiver via a fiber optic port. During drone flight, the fiber optic roll lays out the cable synchronously, enabling data communication between the drone and the ground control terminal. The data captured by the drone is then transmitted to a ground-based display device for display.

[0004] However, traditional fiber optic bins are not very stable when storing fiber optic rolls due to their unreasonable structural design, and the fiber optic rolls are not easy to unload. Utility Model Content

[0005] To address the aforementioned problems, the primary objective of this invention is to provide an optical fiber roll storage bin that can improve the structural stability of the internally installed optical fiber rolls and optical fiber modules.

[0006] Another objective of this invention is to provide an optical fiber roll storage bin that facilitates the unloading of optical fiber rolls.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] This utility model provides an optical fiber roll storage bin, comprising:

[0009] The barrel has a first receiving cavity for accommodating an optical fiber roll and a second receiving cavity for accommodating an optical fiber module. A support partition is provided on the inner wall of the barrel. The first receiving cavity and the second receiving cavity are located above and below the support partition, respectively. The support partition is also provided with a through hole for optical fiber to pass through. The first receiving cavity and the second receiving cavity are connected through the through hole.

[0010] A top cover is attached to the upper end of the barrel body to seal the first receiving cavity;

[0011] A bottom cover is attached to the bottom end of the barrel body to seal the second receiving cavity;

[0012] The top cover has a fiber extraction port at the end opposite to the barrel body, which is connected to the first receiving cavity.

[0013] Furthermore, the top cover, bottom cover, and barrel body are threaded together, which facilitates the installation and maintenance of fiber optic modules and fiber optic rolls.

[0014] Furthermore, the bottom surface of the support partition is provided with several protrusions for fixing the optical fiber module, and the protrusions form an installation area for installing the optical fiber module.

[0015] Furthermore, the bottom surface of the support partition is also provided with a limiting member for limiting the optical fiber connector. The lower end of the optical fiber roll is inserted into the second receiving cavity through the through hole, and then plugged into the socket of the optical fiber module through the optical fiber connector. The limiting member can limit and fix the optical fiber connector, thereby improving the structural stability of the optical fiber module.

[0016] Furthermore, the limiting member has a limiting groove that runs through the front and back, and the limiting groove has an opening on the side away from the supporting partition. The above structure design not only limits the optical fiber connector, but also facilitates the installation and removal of the optical fiber connector.

[0017] Furthermore, the inner wall of the second receiving cavity is also provided with cable management posts for managing optical fiber cables, which can sort out the optical fiber cables entering the second receiving cavity and prevent the optical fiber cables from being messy and disorderly.

[0018] Furthermore, one end of the cable management post is connected to the inner wall of the second receiving cavity, and the other end has a cable management groove between it and the inner wall of the second receiving cavity. An opening for the entry and exit of the optical fiber cable is also provided between the cable management post and the bottom surface of the supporting partition. When the optical fiber cable at the bottom end of the optical fiber roll enters the second receiving cavity, it can enter the cable management groove through the opening for sorting, and then connect to the interface of the optical fiber module through the optical fiber connector. This not only limits the movement of the optical fiber cable but also ensures smoother cable movement.

[0019] Furthermore, the outer wall of the barrel is provided with a socket at the position corresponding to the second receiving cavity, and the on-board optical transceiver of the UAV can be connected to the optical fiber module through the socket to realize optical fiber communication.

[0020] Furthermore, two sets of symmetrical binding posts are provided on the outer wall of the barrel, with two or more binding posts in each set, forming a binding groove between the two binding posts, so that the fiber optic barrel can be easily bound to the drone by Velcro straps.

[0021] Furthermore, the top cover includes an integrally formed barrel docking part, an arc-shaped part, and a tubular part. The barrel docking part, the arc-shaped part, and the tubular part are all hollow structures. One end of the barrel docking part is connected to the upper end of the barrel, and the other end is connected to the tubular part through the arc-shaped part. The fiber pick-up port is located at the end of the tubular part away from the arc-shaped part.

[0022] Furthermore, the inner wall of the arc-shaped part is an arc-shaped smooth surface, which allows the optical fiber cable to slide smoothly out of the barrel and avoids the increase in attenuation caused by the optical fiber tailing.

[0023] Furthermore, the fiber optic port is matched in shape and size to the fiber optic connector, and a protective cap for fixing and protecting the fiber optic connector is also installed on the fiber optic port.

[0024] The beneficial effects of this utility model are as follows: Compared with the prior art, this application installs the fiber optic roll by setting a first receiving cavity and the fiber optic module by setting a second receiving cavity. The fiber optic roll and the fiber optic module are fixed, supported and separated by a support partition, which can improve the structural stability of the fiber optic roll and the fiber optic module. At the same time, the fiber pick-up port opened at the end of the top cover can realize the laying of the fiber optic cable, which can improve the convenience of fiber optic cable laying.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in 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 present utility model and are not intended to limit the present utility model.

[0033] To achieve the above objectives, the technical solution of this utility model is as follows:

[0034] See Figure 1-4 As shown, this embodiment provides an optical fiber roll storage bin, including:

[0035] The barrel 1 has a first receiving cavity 11 for accommodating an optical fiber roll and a second receiving cavity 12 for accommodating an optical fiber module. A support partition 13 is provided on the inner wall of the barrel 1. The first receiving cavity 11 and the second receiving cavity 12 are located above and below the support partition 13, respectively. The support partition 13 is also provided with a through hole 14 for optical fiber to pass through. The first receiving cavity 11 and the second receiving cavity 12 are connected through the through hole 14.

[0036] Top cover 2, which is attached to the upper end of the barrel body 1 to close the first receiving cavity 11;

[0037] Bottom cover 3, which is attached to the bottom end of the barrel body 1 to close the second receiving cavity 12;

[0038] The top cover 2 has a fiber extraction port 4 at the end opposite to the barrel body 1, which is connected to the first receiving cavity 11.

[0039] In this application, the first receiving cavity 11 and the second receiving cavity 12 are used to install the optical fiber roll and the optical fiber module, respectively. The optical fiber roll and the optical fiber module are fixedly supported and separated by the supporting partition 13, which can improve the structural stability of the optical fiber roll and the optical fiber module. The fiber pick-up port 4 opened at the end of the top cover 2 can realize the laying of optical fiber, which can improve the convenience of optical fiber laying.

[0040] Furthermore, the top cover 2, bottom cover 3 and barrel body 1 are threaded together, which facilitates the installation and maintenance of fiber optic modules and fiber optic rolls.

[0041] Furthermore, the bottom surface of the support partition 13 is provided with four protrusions 15 for fixing the optical fiber module. The four protrusions 15 form an installation area 16 for installing the optical fiber module. The protrusions 15 are provided with connection holes, which can be used to install rivets or screws. The optical fiber module is fixed to the installation area 16 on the bottom surface of the support partition 13 by screws or rivets.

[0042] Furthermore, the bottom surface of the supporting partition 13 is also provided with a limiting member 17 for limiting the optical fiber connector. The lower end of the optical fiber roll is inserted into the second receiving cavity 12 through the through hole 14, and then plugged into the socket of the optical fiber module through the optical fiber connector. The limiting member 17 can limit and fix the optical fiber connector, thereby improving the structural stability of the optical fiber module.

[0043] Furthermore, a limiting groove 18 is provided on the limiting member 17. The limiting groove 18 is through the front and back, and the limiting groove 18 has an opening on the side away from the supporting partition 13. The above structure design can not only limit the fiber optic connector, but also facilitate the installation and removal of the fiber optic connector.

[0044] Furthermore, the inner wall of the second receiving cavity 12 is also provided with cable management posts 19 for managing optical fiber cables, which can sort out the optical fiber cables entering the second receiving cavity 12 and prevent the optical fiber cables from being messy and disorderly.

[0045] Furthermore, one end of the cable management post 19 is connected to the inner wall of the second receiving cavity 12, and the other end has a cable management groove 110 between it and the inner wall of the second receiving cavity 12. An opening for the entry and exit of the optical fiber cable is also provided between the cable management post 19 and the bottom surface of the supporting partition 13. When the optical fiber cable at the bottom end of the optical fiber roll enters the second receiving cavity 12, it can enter the cable management groove 110 through the opening for sorting, and then connect to the interface of the optical fiber module through the optical fiber connector. This not only limits the movement of the optical fiber cable but also ensures smoother cable movement.

[0046] Furthermore, the outer wall of the barrel 1 is provided with a socket 111 at the position corresponding to the second receiving cavity 12, and the on-board optical transceiver of the UAV can be connected to the optical fiber module through the socket 111 to realize optical fiber communication.

[0047] Furthermore, two sets of symmetrical binding posts 112 are provided on the outer side wall of the barrel 1. Each set of binding posts 112 has two posts, and a binding groove 113 is formed between the two binding posts 112, so that the fiber optic barrel can be easily bound to the drone by Velcro straps.

[0048] Furthermore, the top cover 2 includes an integrally formed barrel-shaped docking portion 21, an arc-shaped portion 22, and a tubular portion 23. All three portions are hollow. One end of the barrel-shaped docking portion 21 is connected to the upper end of the barrel 1, and the other end is connected to the tubular portion 23 via the arc-shaped portion 22. The fiber optic port 4 is located at the end of the tubular portion 23 opposite to the arc-shaped portion 22. The fiber optic cable at one end of the fiber optic coil within the first receiving cavity 11 can enter the tubular portion 23 from the barrel-shaped docking portion 21 and the arc-shaped portion 22, and then slide out from the fiber optic port 4, thus achieving cable exit.

[0049] Furthermore, the inner wall of the arc-shaped part 22 is an arc-shaped smooth surface, which allows the optical fiber cable to slide smoothly out of the barrel 1 and avoids the optical fiber tailing that leads to increased attenuation.

[0050] Furthermore, the fiber optic port 4 is matched in shape and size to the fiber optic connector, and a protective cap 5 for fixing and protecting the fiber optic connector is also installed on the fiber optic port 4. The shape and size of the fiber optic connector at the end of the fiber optic coil are precisely matched with the fiber optic port 4, enabling stable insertion and removal. When not in use, the fiber optic connector is precisely snapped and fixed on the fiber optic port 4, and secured by the protective cap 5, providing dustproof, anti-loosening, and anti-external damage protection. In this embodiment, the fiber optic connector at the end of the fiber optic coil is an FC-type fiber optic connector, and correspondingly, the shape and size of the fiber optic port 4 are also adapted to the FC-type fiber optic connector. However, in actual products, other types of fiber optic connectors may be used, and the shape and size of the fiber optic port 4 may change accordingly. These changes should all be within the scope of protection of this application.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
