[0002] With the rapid development of drone technology, the stability and security of wireless communication are receiving increasing attention. To address the susceptibility of wireless connections to electromagnetic interference and signal interception, an emerging technology called "fiber optic tether" has emerged. It establishes a stable, high-speed, and interference-resistant "lifeline" between the drone and the ground controller. The fiber optic tether, also commonly referred to as a drone fiber optic tethering system, consists at its core a compact cable reel containing several kilometers of ultra-fine optical fiber. This system is typically installed on the drone or as part of ground equipment. During drone flight, the fiber optic cable is released or retracted, establishing a direct physical connection between the drone and the ground station.

[0003] Existing UAV fiber optic cable technology connects the UAV to the ground control unit via a fiber optic composite cable, achieving stable data transmission and continuous power supply free from electromagnetic interference, thus ensuring long-term aerial operations for UAVs in complex environments. However, in the structures commonly used in existing technologies, the fiber optic composite cable, which serves as the lifeline for the entire system's communication and control, is directly wound and stored outside an open reel or barrel. This design, which completely exposes core components, has inherent and serious safety flaws.

[0004] In view of this, we propose an optical fiber bucket. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 9As shown, this utility model provides a technical solution: an optical fiber barrel, comprising: a housing 1; a base 2, the bottom of the housing 1 being disposed on the base 2; and a drum 31, which is connected to the base 2 and located inside the housing 1. The top of the housing 1 has an optical fiber outlet. An annular rotating drum 32 is rotatably connected to the outer wall of the drum 31. By rotatably connecting the annular rotating drum 32 to the fixed outer wall of the drum 31, a "fixed-axis rotation" winding mechanism is formed, providing a mechanical carrier for the subsequent orderly storage and unloading of optical fibers. The combination of the housing 1 and the base 2 constitutes the external protection and support system of the equipment.

[0023] The base 2 has a flexible buckle 22 on its side wall, a positioning protrusion 23 on its side wall, and an optical fiber cable port 24 on its side wall. The housing 1 has a fixing slot 25 for engaging with the flexible buckle 22, and a positioning groove 26 for engaging with the positioning protrusion 23. The engagement of the flexible buckle 22 and the fixing slot 25 enables quick assembly and disassembly of the base 2 and the housing 1. The engagement of the positioning protrusion 23 and the positioning groove 26 ensures installation accuracy. The optical fiber cable port 24 is the optical fiber channel. These four components work together to ensure the functionality, convenience, and structural stability of the base 2.

[0024] The base 2 has a decoder 5 at its bottom. The outer wall of the decoder 5 is connected to the base 2. The bottom of the base 2 has a mounting groove that matches the shape of the decoder 5. The decoder 5 is embedded in the mounting groove. The mounting groove provides a physical limit for the decoder 5, restricting its horizontal displacement and reducing external impact. The rigid connection between the base 2 and the decoder 5 ensures the stability of optical signal transmission. The embedded design takes into account both protection and space utilization, and is suitable for fixed scenarios of precision electronic components.

[0025] It also includes a press button 43. An adjustment slot 41 is provided on the outer wall of the housing 1. A main body slot 42 is provided on the outer wall of the housing 1. The main body slot 42 is slidably connected to the press button 43. An adjustable buckle 44 is fixedly connected to the side wall of the press button 43. The adjustable buckle 44 is provided with multiple arrays of raised horizontal bars. The adjustable buckle 44 is slidably connected to the adjustment slot 41. The main body slot 42 provides a sliding track for the press button 43. The engagement of the raised horizontal bars of the adjustable buckle 44 with the adjustment slot 41 realizes multi-level pressure adjustment. By controlling the pressure of the press button 43 on the annular rotating drum 32, it can adapt to optical fibers with different winding diameters and prevent the optical fibers from loosening when not in operation.

[0026] The top outer wall of the housing 1 is provided with a mounting slot 61, and a connecting cylinder 62 is inserted into the top of the housing 1. A pressing buckle 63 is connected to the connecting cylinder 62 for aligning with the mounting slot 61. A gooseneck tube 64 is connected to the top of the connecting cylinder 62. The mounting slot 61 and the pressing buckle 63 form a quick-release structure, realizing the tool-based disassembly of the connecting cylinder 62. The flexible bending characteristics of the gooseneck tube 64 allow for multi-angle adjustment of the wire laying path. The combination of the two improves the ease of maintenance and flexibility of use of the equipment.

[0027] The end of the gooseneck tube 64 away from the connecting tube 62 is fixedly connected to a flared end 65. The arc-shaped opening of the flared end 65 is designed to reduce frictional damage between the cable and the edge. The flared structure of the flared end 65 prevents the optical fiber from directly contacting the hard edge when it is led out. The arc-shaped transition design significantly reduces the risk of wear on the surface of the optical fiber. Together with the guiding function of the gooseneck tube 64, it achieves double protection of the optical fiber output end.

[0028] It also includes an annular block 71, which is rotatably connected to the inner wall of the housing 1. Two connecting frames 72 are symmetrically connected to the bottom of the annular block 71, and concave wheels 73 are rotatably connected to the two connecting frames 72. The annular block 71 can rotate freely through bearings, which drives the concave wheels 73 to adjust synchronously with the winding angle. The rotatable connection design of the concave wheels 73 converts the sliding friction between the optical fiber and the component into rolling friction. The "O-shaped channel" formed by the symmetrical distribution of the two wheels provides lateral restraint for the optical fiber, preventing it from shifting or bending.

[0029] The base 2 is made of transparent material, which is used to make it easy to observe the remaining optical fiber. Transparent materials such as acrylic and PC have high light transmittance, allowing users to intuitively judge the remaining optical fiber without disassembling the housing 1, reducing maintenance steps and improving equipment efficiency. It is especially suitable for scenarios that require real-time monitoring of consumable status.

[0030] In use, the fiber optic cable of this invention involves aligning the base 2 with the bottom of the housing 1, inserting the positioning protrusion 23 on the base 2 into the positioning groove 26 of the housing 1 for initial mechanical positioning. Pressing down on the base 2 causes the elastic buckle 22 on its side wall to engage with the fixing groove 25 on the housing 1, completing the secure connection between the base 2 and the housing 1. The elastic buckle 22 utilizes the elastic deformation of the material to engage with the fixing groove 25, providing a stable connection force while facilitating disassembly and maintenance. This ensures accurate relative positioning between the base 2 and the housing 1, preventing installation deviations from affecting the coordinated operation of internal components. Fiber optic cables are then inserted through the fiber optic cable port 24 on the base 2 to connect the fiber optic cable to the drone. The material of the base 2 allows observation of the internal fiber optic cable status, enabling the determination of the remaining fiber quantity without opening the cable.

[0031] The relative rotation between the annular rotating drum 32 and the winding drum 31 enables the smooth release and retrieval of the optical fiber during use, ensuring uniform tension during optical fiber transmission and preventing breakage due to pulling. Through the winding function of the annular rotating drum 32, long optical fibers are tightly and regularly stored inside the housing 1, avoiding bending, wear, or tangling caused by the optical fiber being exposed to the outside. At the same time, the closed structure of the housing 1 further isolates it from external environmental interference.

[0032] The mounting groove restricts the horizontal displacement of the decoder 5 on the base 2, ensuring its relative position is fixed and preventing displacement due to equipment vibration or transportation. It also wraps around the edges of the decoder 5, reducing direct impact from external collisions. The bolted connection provides stronger fixing force than clips or glue, ensuring the decoder 5 remains secure during long-term use. At least two bolts symmetrically distributed along the central axis ensure even stress distribution on the decoder 5, preventing deformation of the base 2 or decoder 5 due to unilateral stress, ensuring a tight fit and reducing resonance noise. The mounting groove provides initial physical positioning, while the bolts further lock the position, forming a dual guarantee of "mechanical limiting + rigid fixing." This ensures the coaxiality and perpendicularity of the decoder 5 and base 2, preventing installation deviations from affecting fiber optic connection accuracy. The bolted connection also supports tool-based disassembly, facilitating individual replacement or repair of the decoder 5. Compared to a non-removable integrated design, this is more flexible. This combination of "mechanical limiting + rigid fixing + stress optimization" ensures both the accuracy and stability of the decoder 5 installation while also considering equipment protection and maintainability, making it suitable for precision equipment scenarios with high requirements for the reliability of electronic component fixation.

[0033] The adjustable latch 44 on the side wall of the press button 43 has multiple arrayed raised horizontal bars that can be engaged in the adjustment slot 41 on the outer wall of the housing 1. By selecting different positions of the raised horizontal bars to engage with the slot, the position of the press button 43 can be adjusted, thereby controlling the pressure on the annular drum 32. The spacing of the raised horizontal bars forms "gear positions," which the user can switch between by pressing or pulling the press button 43 to accommodate optical fibers with different winding diameters. The main body slot 42 on the outer wall of the housing 1 provides a sliding track for the press button 43, ensuring the stability of the movement direction of the press button 43 during adjustment and avoiding displacement that could lead to positioning failure.

[0034] The mounting slot 61 and the press-fit buckle 63 form a quick-release structure. The press-fit buckle 63 can be elastically inserted into the mounting slot 61 to fix the connecting cylinder 62 to the housing 1. During disassembly, pressing the buckle 63 will separate the cylinder. The gooseneck tube 64 at the bottom of the connecting cylinder 62 has the ability to be bent and shaped at any angle, and the flared end 65 can be manually adjusted to guide it to the target position. The flared design of the flared end 65 facilitates the smooth exit of the cable after it enters the connecting cylinder 62, while reducing friction damage between the cable and the edges. The overall structure, through the combination of "buckle fixing + flexible guidance + flared protection," achieves flexible adjustment of the cable laying path and safe protection of the cable.

[0035] Two concave wheels 73 have their outer edges abutting against each other, and their concave portions are positioned opposite each other, allowing the optical fiber to pass through the channel formed by the concave portions of the two concave wheels 73. The annular block 71 is rotatably connected to the inner wall of the housing 1 via a bearing, and can rotate smoothly around the central axis of the housing 1, thereby driving the two connecting frames 72 at the bottom and the concave wheels 73 to adjust their overall angle. The outer edges of the two concave wheels 73 abut against each other, and their concave portions are positioned opposite each other to form an "O-shaped channel." When the optical fiber passes through the channel, the arc-shaped contact surface of the concave wheel 73 can adapt to the diameter of the optical fiber and provide lateral restraint, preventing the optical fiber from shifting or bending. The concave wheel 73 is rotatably connected to the connecting frame 72, and when the optical fiber passes through, it can drive the concave wheel 73 to roll synchronously, converting sliding friction into rolling friction and reducing wear on the surface of the optical fiber. The overall structure, through the design of "rotational adjustment + rolling guidance + elastic restraint," achieves multi-angle turning of the optical fiber and low-damage transmission within the housing 1.
