Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a three-dimensional intelligent hangar for UAVs. Background Technology

[0002] With the development of science and technology, drones are widely used, and drone hangars are rapidly developing. A drone intelligent three-dimensional hangar refers to a drone parking facility with multi-level storage and automatic scheduling capabilities. It is a multi-functional site specifically designed for drones, integrating parking, charging, and maintenance, providing drones with storage, charging, data exchange, and weather protection functions.

[0003] Currently, in intelligent drone hangars, drones need to enter and exit the hangar sequentially through a central lifting platform. Under high-frequency tasks, this can easily lead to queuing bottlenecks and prevent multiple drones from responding quickly at the same time. With only a single entrance and exit, drone retrieval and placement rely on complex track switching mechanisms, which can easily cause problems such as jamming and inaccurate positioning.

[0004] Therefore, there is an urgent need for an intelligent three-dimensional warehouse for drones with large-capacity three-dimensional storage, high degree of automation, and efficient take-off and landing scheduling, in order to adapt to the development trend of drone swarm operations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a three-dimensional intelligent hangar for unmanned aerial vehicles (UAVs). The three-dimensional intelligent hangar can not only store multiple UAVs, but also realize the parallel take-off and landing of UAVs, thus solving the technical problem of low efficiency of UAV entry and exit in the prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A three-dimensional intelligent hangar for unmanned aerial vehicles (UAVs) includes: The hangar body has multiple sets of landing dams arranged around it, and support plates are placed on the landing dams for parking drones; the top surface of the hangar body has a take-off and landing port; A circular track is provided on the inner bottom surface of the tank body, and the landing port is projected onto the circular track. A retraction and deployment mechanism, which displaces along the circular track, includes a gripping component and a lifting component. The gripping component grips a corresponding support plate on the landing dam, and the lifting component raises the gripping component to or lowers it from the landing opening. An timing module is electrically connected to the take-up and take-down mechanism and is used to drive the take-up and take-down mechanism.

[0007] The beneficial effects of this invention are as follows: Through the three-dimensional design of the helipad, compared to traditional single-layer planar hangars, the storage capacity of drones is significantly increased, enabling the orderly storage of multiple drones in designated areas. The deployment and retrieval mechanism, through the coordinated work of lifting and gripping components, can flexibly adjust the position of drones. Accurate positioning and movement control via a circular track enable automated movement of drones from storage locations to take-off and landing points. The deployment and retrieval mechanism, in conjunction with the aircraft selection module, achieves fully automated drone retrieval and deployment, and also fully automated drone retrieval, deployment, and scheduling. This significantly reduces drone take-off and landing waiting time and improves take-off and landing efficiency. Simultaneously, the hangar provides protection for internal components, further ensuring a stable drone storage environment and extending equipment lifespan. The three-dimensional intelligent drone hangar of this application features a high degree of automation, large storage capacity, and high scheduling efficiency, making it suitable for drone swarm operations in various scenarios.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the lifting assembly includes a base, a lifting platform, and a lifting drive component; the base moves along the annular track, the lifting platform is slidably connected to the base via a lifting guide rail, and the lifting drive component is fixedly connected to one side of the base for driving the lifting platform to rise or fall.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the lifting platform and the base are connected by lifting guide rails to form a structure that can extend and retract vertically, and the lifting drive provides sufficient power support for the lifting platform.

[0011] Furthermore, the lifting drive component includes a drive motor and a steel wire rope. The drive motor is fixed on the base, one end of the steel wire rope is connected to the output end of the drive motor, and the other end is connected to the lifting platform. The drive motor drives the lifting platform to move up and down by winding and unwinding the steel wire rope.

[0012] The beneficial effects of adopting the above-mentioned further solution are: by combining the lifting guide rail with the wire rope drive, the platform can be raised and lowered smoothly, and the risk of jamming can be reduced by the flexible traction of the wire rope.

[0013] Furthermore, the gripping assembly includes a telescopic rod and a telescopic motor. The telescopic motor is fixed on the lifting platform, and the output direction of the telescopic motor is horizontal. One end of the telescopic rod is connected to the output end of the telescopic motor, and the other end is connected to a support claw, which is used to grip the support plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the telescopic motor drives the telescopic rod to move horizontally, so that the support claw can directly and accurately grab or put back the support plate from the side, without the need for a lifting platform or drone to make complex lateral adjustments.

[0015] Furthermore, the lifting platform is also connected to a first slide rail, which is parallel to the telescopic rod. The bottom of the support plate is connected to a roller assembly, which is used to slide with the first slide rail.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the first slide rail provides physical constraints on both sides of the support plate, preventing it from shifting laterally, tilting, or swaying during transfer. This is crucial for protecting the drone (especially the landing gear) parked on it, avoiding equipment damage caused by sudden bumps or misalignment.

[0017] Furthermore, a track trolley is connected to the bottom of the base, and the track trolley moves along the circular track.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the track trolley rolls on the circular track by means of wheels, which greatly reduces the moving resistance compared to the sliding friction method.

[0019] Furthermore, the receiving and releasing mechanism is provided in multiple sets, and multiple lifting and lowering ports are opened on the top surface of the storage body, with each of the multiple lifting and lowering ports corresponding to a different set of receiving and releasing mechanisms.

[0020] The beneficial effects of adopting the above-mentioned further solution are that multiple sets of deployment and retrieval mechanisms can work independently and simultaneously, allowing multiple drones to be retrieved, prepared, launched, or recovered and stored at the same time.

[0021] Furthermore, each of the take-off and landing ports is equipped with a hatch, which is a folding door.

[0022] The beneficial effect of adopting the above-mentioned further solutions is that the storage facility forms a closed indoor environment, effectively isolating the drones and precision equipment inside from rain, snow, wind, sand, dust, ultraviolet rays and extreme temperatures.

[0023] Furthermore, each of the aforementioned shutdown dams includes a frame and a region division and positioning component, the frame is provided with a storage space, and the support plate is placed in the storage space; The area division and positioning component is electrically connected to the timing module and includes a positioning post, a position sensor, and a number plate. The positioning post is located next to the storage location, and the position sensor and the number plate are both located on the positioning post. The position sensor is used to detect whether there is a drone in the storage location, and the number plate is used to mark the storage location number and the corresponding drone information.

[0024] The beneficial effects of adopting the above-mentioned further solutions are: the timing module can grasp the information of the drone in real time, providing the most direct data basis for the scheduling, storage and task allocation of the drone, and realizing dynamic inventory management.

[0025] Furthermore, a second slide rail is connected to the frame, and the support plate is slidably connected within the second slide rail.

[0026] The beneficial effect of adopting the above-mentioned further solution is that it, together with the first slide rail on the lifting platform, forms a continuous track docking system. Attached Figure Description

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] according to Figures 1 to 6As shown in the figure, this application provides an embodiment of an unmanned aerial vehicle (UAV) three-dimensional intelligent hangar, including: The storage body 1 has multiple sets of landing dams 2 arranged around it. Support plates 23 are placed on the landing dams 2 for parking drones. The top surface of the storage body 1 has a take-off and landing port 11. A circular track 41 is provided on the inner bottom surface of the tank body 1, and the landing port 11 is projected onto the circular track 41. A retraction mechanism 3, which moves along the annular track 41, includes a gripping component and a lifting component. The gripping component grips the corresponding support plate 23 on the landing dam 2, and the lifting component lifts the gripping component to or lowers it from the landing opening 11. An timing module is electrically connected to the take-up and take-down mechanism 3 and is used to drive the take-up and take-down mechanism 3.

[0031] The timing module includes a positioning module, a control module, and an execution module. The positioning module includes a laser emitter and a displacement encoder. The laser emitter is used to detect the position of a preset point on the landing pad, and the displacement encoder is used to record the movement distance of the deployment and take-up mechanism 3. The control module is connected to the position sensor on the landing pad and controls the execution module to work based on the data detected by the positioning module. The execution module is connected to the control module and is used to drive the deployment and take-up mechanism 3 to the required UAV storage point.

[0032] The laser emitter emits a laser beam toward a preset marker point on the helipad and calculates the distance deviation between the retraction mechanism 3 and the target position by receiving the reflected signal. Simultaneously, a displacement encoder detects and records the movement displacement of the retraction mechanism 3 in real time. The two work together to achieve high-precision positioning of the retraction mechanism 3. The control module uses a PLC to pre-set parameters such as lifting height and extension length for each storage location and generates control commands for the lifting components and extension rod 35 based on data feedback from the positioning module. After receiving the control commands, the execution unit drives the retraction mechanism 3 to move along a predetermined trajectory, ensuring accurate movement to the target position on the helipad.

[0033] The laser emitter in the positioning module is a semiconductor laser emitter with a wavelength of 650nm, a positioning distance range of 0.5-10m, and a positioning accuracy of ±0.5mm. The displacement encoder is an incremental encoder, capable of recording the movement displacement of the positioning module in real time. The control module uses a Siemens S7-1200 PLC controller, which presets the stroke of the gripping component and the height of the lifting component for different storage locations. Based on the positioning detection data, it automatically adjusts the actions of the take-up and take-down mechanism 3 to achieve precise drone transport.

[0034] This application's embodiment, through a three-dimensional design of the helipad, significantly increases the storage capacity of drones compared to traditional single-layer planar hangars 1, enabling the orderly, partitioned storage of multiple drones. The deployment and retrieval mechanism 3, through the coordinated operation of lifting and gripping components, can flexibly adjust the drone's position. Accurate positioning and movement control via the circular track 41 enable automated movement of drones from storage locations to take-off and landing points. The deployment and retrieval mechanism 3, in conjunction with the aircraft selection module, achieves fully automated drone retrieval and deployment, as well as fully automated drone retrieval, deployment, and scheduling. This significantly reduces drone take-off and landing waiting time and improves take-off and landing efficiency. Simultaneously, the hangar 1 provides protection for internal components, further ensuring a stable drone storage environment and extending equipment lifespan. This application's three-dimensional intelligent drone hangar boasts a high degree of automation, large storage capacity, and high scheduling efficiency, making it suitable for drone swarm operations in various scenarios.

[0035] Based on the above technical solution, the present invention can be further improved as follows.

[0036] Preferably, in an embodiment, the lifting assembly includes a base 31, a lifting platform 32, and a lifting drive component 33; the base 31 is displaced along the annular track 41, the lifting platform 32 is slidably connected to the base 31 via a lifting guide rail 36, and the lifting drive component 33 is fixedly connected to one side of the base 31 for driving the lifting platform 32 to rise or fall.

[0037] In this embodiment, the lifting platform 32 and the base 31 are connected by a lifting guide rail 36 to form a structure that can extend and retract vertically, and the lifting drive component 33 provides sufficient power support for the lifting platform 32.

[0038] The lifting platform 32 is connected to the base 31 via a rigid lifting guide rail 36, ensuring that the lifting platform 32 moves only in the vertical direction during lifting, effectively resisting swaying, tilting, or torsion caused by lateral forces or off-center loads. This provides a solid foundation for the safety of the UAV during lifting and the precise alignment of subsequent grabbing / storage operations. The guide rail pair provides high rigidity while also allowing for micron-level motion precision, enabling the lifting platform 32 to accurately stop at any height aligned with the landing dam 2.

[0039] The base 31 bears and transmits all loads from the rails and drive components to the ground rail system. The lifting guide rail 36 directly and vertically transmits the gravity and inertial forces of the lifting platform 32 and its load (UAV, support plate 23) to the base 31. This design makes the force path clear and reasonable, avoiding complex internal stresses. The stable base 31 serves as the chassis of the entire lifting assembly, and its firm connection with the circular rail 41 (e.g., via the rail trolley 42) provides an extremely stable reference benchmark for the lifting platform 32 during high-altitude operations.

[0040] Preferably, in an embodiment, the lifting drive component 33 includes a drive motor 331 and a wire rope 332. The drive motor 331 is fixed to the base 31, and one end of the wire rope 332 is connected to the output end of the drive motor 331, while the other end is connected to the lifting platform 32. The drive motor 331 drives the lifting platform 32 to move up and down by winding and unwinding the wire rope 332. Specifically, according to Figure 7 As shown, the drive motor 331 outputs rotational power, which is transmitted through the transmission shaft to drive the transmission wheels at both ends to rotate, thereby driving the wire rope 332 to be wound and unwound. A platform connector 39 is provided on the side of the lifting platform 32 near the drive motor 331. The platform connector 39 is connected to one end of the wire rope 332, and finally the lifting platform 32 is pulled to complete the lifting and lowering along the preset lifting guide rail 36, thereby realizing the position adjustment of the lifting platform 32.

[0041] In this embodiment, a combination of lifting guide rail 36 and wire rope 332 transmission is used to ensure smooth platform lifting and lowering while reducing the risk of jamming through the flexible traction of the wire rope 332. The lifting guide rail 36 consists of multiple parallel channel steels mounted on the frame 21 of the take-up and release mechanism 3. The drive motor 331 is a variable frequency servo motor, which can control the take-up and release speed of the wire rope 332 by adjusting the frequency, thereby controlling the lifting speed of the lifting platform 32 to meet the transfer requirements of storage positions at different heights. The wire rope 332 is made of high-strength galvanized steel wire rope with a diameter of 8-12mm, possessing strong load-bearing capacity and wear resistance, ensuring the long-term stable operation of the lifting components.

[0042] Preferably, in an embodiment, the gripping component includes a telescopic rod 35 and a telescopic motor 34. The telescopic motor 34 is fixed on the lifting platform 32, and the output direction of the telescopic motor 34 is horizontal. One end of the telescopic rod 35 is connected to the output end of the telescopic motor 34, and the other end is connected to a support claw 38, which is used to grip the support plate 23.

[0043] Specifically, the telescopic boom 35 features a large telescopic stroke and stable structure. The telescopic stroke can be set from 0-1.5m, meeting the distance adjustment requirements between the support plate 23 and the landing pad / take-off / landing point. The telescopic motor 34 is a servo motor. It offers the advantages of controllable speed and precise positioning. The motor speed can be adjusted via a PLC controller to achieve uniform telescopic boom 35 extension and retraction, ensuring the stability of the drone during transport and preventing swaying due to excessive extension speed. The telescopic boom 35 achieves multi-stage extension and retraction through chain drive, and a locking device ensures stability when the boom extends to a certain length. Figure 4As shown, in this embodiment, the telescopic rod 35 of the retracting mechanism 3 is made of aluminum alloy, with a maximum telescopic stroke of 1.5m and a telescopic speed that is adjusted by the telescopic motor 34, with an adjustment range of 0.1-0.5m / s.

[0044] In this embodiment, the telescopic motor 34 drives the telescopic rod 35 to move horizontally, enabling the support claw 38 to directly and accurately grab or return the support plate 23 from the side, without requiring complex lateral adjustments by the lifting platform 32 or the drone. This decouples the vertical lifting and horizontal retrieval actions, simplifies the operation process, and improves the retrieval speed. The grabbing action is performed when the lifting platform 32 is stationary at the corresponding height of the parking dam 2, forming a continuous and efficient automated assembly line operation with the movement of the track and the lifting of the platform.

[0045] The gripping component targets the support plate 23, rather than directly gripping the drone. This avoids potential scratches, squeezing, or signal interference that could occur from direct contact between the mechanical gripper and the drone body, maximizing the safety of the drone. The gripping component is applicable as long as the drone is placed on the standardized support plate 23, offering greater compatibility with differences in drone model, size, and landing gear structure, thus improving the versatility of the hangar 1.

[0046] Furthermore, the telescopic motor 34 is horizontally fixed to the lifting platform 32, and the telescopic rod 35 extends and retracts horizontally, making full use of the side space of the lifting platform 32 and avoiding the need for complex mechanisms stacked in the vertical direction. This allows for control of the overall height of the lifting platform 32, enabling the design of a denser vertical parking dam 2 in the warehouse 1, further improving space utilization. The timing module can coordinate the movement of the circular track 41 (positioning to the correct parking dam 2), the lifting and lowering of the lifting platform 32 (positioning to the correct height), and the extension and retraction of the telescopic rod 35 (precise gripping / releasing), achieving precise coordinate positioning and operation in three-dimensional space. The telescopic motor 34 and the end support claw 38 can integrate position sensors, pressure sensors, etc., to provide real-time feedback of the gripping status to the timing module, forming a closed-loop control to ensure the safety and reliability of operation.

[0047] Preferably, in an embodiment, the lifting platform 32 is further connected to a first slide rail 37, the first slide rail 37 is parallel to the telescopic rod 35, and the bottom of the support plate 23 is connected to a roller assembly, the roller assembly being used to slide in connection with the first slide rail 37.

[0048] In this embodiment, when the telescopic rod 35 pushes the support plate 23, the roller assembly at the bottom of the support plate 23 engages with the first slide rail 37 on the lifting platform 32. This changes the movement of the support plate 23 from "sliding friction" to "rolling friction," significantly reducing motion resistance and ensuring that even when carrying a heavy drone, it can be smoothly and easily pulled into or out of the lifting platform 32. The first slide rail 37 provides physical constraints on both sides of the support plate 23, preventing it from shifting laterally, tilting, or swaying during transfer. This is crucial for protecting the drone (especially the landing gear) parked on it, avoiding equipment damage caused by sudden bumps or misalignment.

[0049] The first slide rail 37 acts as a rigid guide reference, ensuring that the support plate 23 automatically aligns and reaches a unique and precise preset position each time it is pulled into the lifting platform 32. This reduces reliance on visual sensors or complex positioning algorithms, improving the system's reliability and speed. When the support plate 23 is returned to the parking dam 2, the rollers extend along the first slide rail 37, naturally guiding the support plate 23 back to its original position accurately, achieving hard positioning and greatly improving the success rate of the storage operation.

[0050] The weight of the support plate 23 and the drone on it is evenly transferred to the robust first slide rail 37 and lifting platform 32 structure via rollers, rather than being entirely borne by the telescopic rod 35 and its drive mechanism. This significantly reduces the load on the telescopic motor 34 and the telescopic rod 35, minimizing their deformation and wear, and extending the service life of the core moving components. When the support plate 23 is fully retracted into the lifting platform 32, the cooperation between the rollers and the slide rail forms a stable whole, enhancing the overall structural rigidity of the lifting platform 32 during lifting and movement, and improving the system's vibration resistance. Even if minor deformation or installation errors occur in the structure of the storage unit 1 or the track after prolonged use, the roller and slide rail cooperation mechanism can make certain adaptive adjustments through rolling, providing stronger fault tolerance compared to purely rigid push-pull mechanisms.

[0051] Preferably, in this embodiment, a track trolley 42 is connected to the bottom of the base 31, and the track trolley 42 moves along the annular track 41. The annular track 41 is an I-beam track with a diameter of 5m, and is coaxially arranged with the helipad. The rollers at the bottom of the track trolley 42 roll in contact with the track surface of the annular track 41, with a rolling friction coefficient ≤0.02. The servo motor has a power of 1kW and a speed adjustment range of 0-1500r / min, and the moving speed of the track trolley 42 can be controlled by pulse signals.

[0052] In this embodiment, the track trolley 42 rolls on the circular track 41 via its wheels, significantly reducing movement resistance compared to sliding friction. This results in lower power requirements and smoother movement, enabling rapid and low-energy displacement even when carrying the weight of the entire deployment and take-off mechanism 3 (lifting platform 32, base 31, etc.), including the drone. The wheels of the track trolley 42 typically have matching flanges or guide structures to ensure it runs strictly along the predetermined circular path without deviation or derailment, providing a fundamental guarantee for precise positioning of the target landing dam 2.

[0053] The track trolley 42 distributes the concentrated load of the deployment and take-off mechanism 3 to the robust circular track 41 via its wheels. This design optimizes stress distribution, reduces localized pressure on the circular track 41 and the foundation of the storage unit 1, and enhances structural safety for long-term use. A stable and movable base 31 is a prerequisite for the smooth lifting and lowering operation of the lifting platform 32. The track trolley 42 provides a stable and level reference surface for the base 31, ensuring that the UAV will not be at risk due to foundation swaying during lift-off.

[0054] Preferably, in the embodiment, the take-up and take-down mechanism 3 is provided in multiple sets, and multiple lifting and lowering ports 11 are opened on the top surface of the storage body 1, and the multiple lifting and lowering ports 11 correspond to the multiple sets of take-up and take-down mechanisms 3 respectively.

[0055] In this embodiment, multiple sets of take-up and drop-off mechanisms 3 can operate independently and simultaneously, allowing multiple drones to be retrieved, prepared, launched, or retrieved and stored at the same time. This solves the waiting queue problem caused by the serial operation of a single take-up and drop-off mechanism 3, resulting in a multiplier increase in the overall scheduling capacity of the warehouse 1. For scenarios requiring simultaneous deployment or rapid rotation of drone swarms, such as logistics transfers, large-area inspections, and emergency responses, this design is a core infrastructure for ensuring mission timeliness.

[0056] When a fault occurs in one of the receiving / delivering mechanisms 3, requiring maintenance, the other mechanisms can continue to operate. The storage unit 1 only experiences a decrease in capacity rather than complete failure, greatly enhancing system availability and robustness. The timing module can intelligently allocate tasks, preventing overuse of any single device. Furthermore, maintenance work can be carried out by the different units in rotation without affecting overall operation.

[0057] Different take-off and landing ports 11 can point to different external work areas. The selection module can intelligently choose the optimal entrance / exit based on the mission destination, reducing unnecessary flights after the drone leaves the hangar. Different types of operations can be diverted to different channels based on drone model, mission priority, or energy status, achieving more refined operation management.

[0058] The timing module can direct the launch and recovery mechanism 3, which is closest to the target UAV, to grab it, significantly reducing the idle travel time of the launch and recovery mechanism 3 on the track, thereby shortening the overall time from mission notification to UAV takeoff, which is especially suitable for emergency missions.

[0059] Preferably, in the embodiment, each of the take-off and landing ports 11 is provided with a hatch 12, and the hatch 12 is a folding door.

[0060] In this embodiment, when the drone is not operating, the folding door is closed, creating a closed indoor environment within the hangar 1. This effectively isolates the drone and precision equipment from rain, snow, sandstorms, dust, ultraviolet radiation, and extreme temperatures. This significantly extends equipment lifespan and reduces maintenance frequency and costs. During takeoff and landing, the hatch 12 can be quickly opened to create a partial passageway, minimizing external environmental interference (such as gusts of wind and rain) during the high-risk phases of takeoff and landing, thus improving operational safety and reliability.

[0061] Compared to hinged or sliding doors, folding doors can be stacked vertically when open, taking up almost no valuable space on the outer or inner side of the top of the storage unit 1. This allows for a more densely packed design of multiple openings 11 without requiring a large amount of space for door swing. When closed, the multiple door panels of the folding door can form a flat or continuous surface that matches the curvature of the top, helping to maintain the overall structural strength, airtightness, and neat appearance of the top of the storage unit 1.

[0062] The closed hatch 12 is crucial for maintaining a stable internal temperature within the storage tank 1. This is especially important for applications requiring battery storage, charging, or equipment maintenance in a constant temperature or air-conditioned environment, significantly reducing energy consumption. It also enables the implementation of environmental control measures such as dehumidification, air filtration, or micro-positive pressure dust control within the storage tank 1, creating an ideal storage environment for precision electronic equipment.

[0063] Preferably, in the embodiment, each group of the stop dam 2 includes a frame 21 and a region division and positioning component, the frame 21 is provided with a storage space, and the support plate 23 is placed in the storage space; The area division and positioning component is electrically connected to the timing module and includes a positioning post 24, a position sensor, and a number plate. The positioning post 24 is located next to the storage location. The position sensor and the number plate are both located on the positioning post 24. The position sensor is used to detect whether there is a drone in the storage location, and the number plate is used to mark the storage location number and the corresponding drone information.

[0064] Specifically, the helipad frame 21 is arranged in a circle around the central support column, which can make full use of the space inside the storage unit 1 and significantly increase the storage capacity. The position sensors of the partition positioning component can detect the occupancy status of the storage positions in real time, avoiding the problem of misplacement or duplicate storage when storing drones. The number plate can mark the storage position number, drone model, battery level and other information, which can facilitate the staff to quickly identify and manage, and improve the accuracy and convenience of scheduling in the storage unit 1.

[0065] like Figure 3 As shown, in this embodiment, the frame 21 is constructed from aluminum alloy. The diameter of the frame arranged around the central support column is 6m, and the layer spacing is 2m, ensuring that the drones do not interfere with each other during storage. There are a total of 12 evenly distributed storage slots, each measuring 1.2m × 1.2m, sufficient to accommodate multi-rotor drones. The support plate 23 is made of rubber with a thickness of 5mm and features anti-slip textures on its surface, which not only absorbs impact but also prevents the drones from sliding. The roller assembly, including rollers and roller seats, is installed at the bottom of the support plate 23 and is adapted to the first slide rail 37 of the take-up and take-down mechanism 3. Through the linkage between the first slide rail 37 and the roller assembly, the support plate 23 slides horizontally, facilitating the take-up and take-down mechanism 3 to retrieve and place the drones. The partition positioning component uses infrared sensors installed on the outside of the storage slots. When a drone is stored in a storage slot, the infrared sensor is blocked, sending an occupancy signal to the control module; when it is not blocked, it sends an idle signal. The number plate uses an electronic tag, which is placed on the inner edge of the storage slot to display information such as the storage slot number and the drone's battery level.

[0066] In this embodiment, a position sensor (such as an infrared, ultrasonic, or pressure sensor) next to each storage slot can automatically detect in real time whether there is a drone (or support plate 23) at that slot. This information is directly fed back to the scheduling module, forming an accurate storage status map. The scheduling module can know in real time which slots are vacant and which are occupied, providing the most direct data basis for drone scheduling, storage, and task allocation, and realizing dynamic inventory management.

[0067] The positioning post 24 itself provides a clear physical reference for the visual or mechanical positioning of the take-up and take-down mechanism 3. Combined with a unique number plate, each storage location is assigned precise physical coordinates and a logical number. The take-up and take-down mechanism 3 can quickly identify the positioning post 24 and the number plate, achieving millimeter-level precise docking and alignment, greatly improving the success rate and speed of the grasping and storage actions.

[0068] By combining the drone's status (battery level, mission type, health status) with the real-time status of the storage slots, the timing module can intelligently plan the movement path of the deployment and retrieval mechanism 3, prioritizing the nearest or most suitable available slot, or urgently retrieving specific drones to achieve optimal overall efficiency. After summarizing the status information of all storage slots, operators can have a clear overview of the entire fleet (which drones are performing missions, which are in storage, and which are charging), facilitating macro-level decision-making.

[0069] The number plates clearly indicate the storage location number and the corresponding drone information (such as serial number and model), greatly facilitating manual inspection, maintenance, replacement, or manual operation in special circumstances. When a storage location or drone malfunctions, its number and location information can help maintenance personnel quickly and accurately pinpoint the problem, shortening troubleshooting and repair time.

[0070] Long-term collected data on storage space occupancy and drone entry / exit frequencies can be used to analyze warehouse 1 utilization, predict maintenance cycles, and optimize fleet size, enabling data-driven, refined operations. Positioning post 24 can serve as a platform for integrating more sensors, such as environmental sensors (monitoring temperature and humidity) or charging status sensors, and can be easily upgraded to a smart charging station or deep maintenance station in the future.

[0071] Preferably, in an embodiment, the frame 21 is further connected to a second slide rail 22, and the support plate 23 is slidably connected within the second slide rail 22.

[0072] In this embodiment, the second slide rail 22 provides physical guidance for the support plate 23 on the storage side. When the support plate 23 is pushed into the storage position by the retraction mechanism 3, the roller assembly at its bottom can smoothly engage with the second slide rail 22, ensuring that the support plate 23 can reach a unique and highly repeatable preset position each time, thus eliminating storage errors.

[0073] After the support plate 23 is fully slid in, its weight and load are evenly distributed to the second slide rail 22 and the sturdy frame 21 via the roller assembly. This rigid connection effectively prevents any shaking, sliding or tilting of the support plate 23 during storage, providing an extremely stable parking platform for the drone.

[0074] This design, together with the first slide rail 37 on the lifting platform 32, forms a continuous track docking system. During storage and retrieval, the support plate 23 is smoothly transferred as if between two precisely aligned tracks, achieving zero-impact, low-resistance transfer from the mobile vehicle to the fixed shelf. This track docking method minimizes the bumps, vibrations, and lateral stress on the support plate 23 and the drone above it during storage and retrieval, fundamentally avoiding mechanical damage that may be caused by rough docking.

[0075] The drone launch process is as follows: 1. The positioning module of the timing module detects the storage position of the landing pad through a laser emitter, the displacement encoder records the movement distance of the take-up and take-down mechanism 3, and the control module drives the execution module according to the detected data to make the take-up and take-down mechanism 3 move to the target storage position.

[0076] 2. The lifting component of the take-up and release mechanism 3 starts the variable frequency servo motor, and the take-up and release steel wire rope 332 drives the lifting platform 32 to rise along the lifting guide rail 36 to the second floor height. Then the telescopic motor 34 of the grabbing component drives the telescopic rod 35 to extend and move to directly below the target storage position.

[0077] 3. After the support claw 38 at the front end of the telescopic rod 35 moves to the preset position, the lifting platform 32 rises. Then the telescopic rod 35 retracts, transporting the support plate 23 carrying the drone to the top of the lifting platform 32.

[0078] 4. The track trolley 42 moves along the circular track 41 to directly below the take-off and landing port 11, the hatch 12 opens, the lifting platform 32 rises to its highest position, the UAV takes off from the support plate 23, and the hatch 12 closes. The take-off process is complete.

[0079] The drone retrieval process is as follows: 1. Based on the information provided by the position sensors on the landing pad, the timing module drives the track trolley 42 to move the take-up and drop-off mechanism 3 to the vacant storage position. The lifting platform 32 rises to the designated height, the telescopic rod 35 extends directly below the target storage position, and after the support claw 38 is in place, the lifting platform 32 rises, moving the support plate 23 on the storage position into the take-up and drop-off mechanism 3.

[0080] 2. The top hatch 12 of the tank body 1 opens, the track trolley 42 moves to directly below the landing port 11, the lifting platform 32 rises to the highest point, and the telescopic rod 35 remains in the retracted state.

[0081] 3. The drone lands on the support plate 23 at the front end of the telescopic pole 35, the lifting platform 32 moves to the height of the target storage location, and the hatch 12 closes.

[0082] 4. The control module of the timing module drives the take-up and take-down mechanism 3 to the corresponding position based on the information of the target storage location on the apron.

[0083] 5. The telescopic pole 35 extends, moving the support plate 23 carrying the drone to the target storage location. The lifting platform 32 descends to a certain height to store the drone in the target storage location. The telescopic pole 35 retracts, and the lifting component drives the lifting platform 32 to the lowest point, completing the drone retrieval process.
