Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) take-off and landing platform technology, and in particular to a height-adjustable UAV take-off and landing platform. Background Technology

[0002] A drone takeoff and landing platform provides a flat and stable surface for drones to take off and land, preventing takeoff and landing failures caused by uneven ground or debris (e.g., a dedicated platform is needed for grassy or muddy ground in field operations). In traditional agricultural or forestry scenarios, the ground is densely vegetated and full of obstacles. Taking off and landing at low altitudes can easily cause drone propellers to get caught in branches and leaves, and dust can clog the engine. Furthermore, pesticide spraying can contaminate the platform. Therefore, drone takeoff and landing platforms are often installed at high altitudes, allowing drones to take off and land above the vegetation layer. This avoids ground obstacles and dust, reduces engine damage, lowers the risk of pesticide contamination, improves takeoff and landing stability, shortens the time to reach operating height, and increases operational efficiency. However, this installation method places the drone and the support frame at a high position, requiring climbing for maintenance, which inconveniences the process. Utility Model Content

[0003] The purpose of this utility model is to address the problem that in traditional agriculture or forestry, due to dense ground vegetation and numerous obstacles, low-altitude take-off and landing can easily lead to drone malfunctions and platform contamination. Therefore, take-off and landing platforms are often installed at high places to avoid risks and improve operational efficiency. However, this makes the drone and its support structure high up, and maintenance requires climbing to a height, which is inconvenient. This utility model proposes a drone take-off and landing platform with adjustable height.

[0004] The technical solution of this utility model is as follows: A height-adjustable UAV take-off and landing platform, including a base and a take-off and landing platform, and further including: a base rod, fixedly connected to the top of the base; a first insert rod and a second insert rod sequentially installed on the top of the base rod, the top end of the second insert rod being fixedly connected to the take-off and landing platform, and a steel wire rope provided at one end of the base rod and the first insert rod to extend the first insert rod and the second insert rod when tensioned; a rope winch mechanism disposed in the base to drive the tension of the steel wire rope; and a locking mechanism disposed in the base to lock the rope winch mechanism so that it cannot rotate.

[0005] Optionally, the rope winding mechanism includes a pair of mounting cavities within a base, one of which houses a first rotating shaft motor, and the other of which houses a second dual-shaft motor. The output shafts at both ends of the first rotating shaft motor and the second dual-shaft motor are fixedly connected to a pair of movable connecting rods that penetrate the base. The ends of the connecting rods away from the first rotating shaft motor and the second dual-shaft motor are fixedly connected to a winding wheel, and the winding wheel is fixedly connected to the corresponding end of the wire rope.

[0006] Optionally, the ends of the first and second inserts are provided with through holes for the steel wire rope to pass through, and the ends of the bottom rod and the first insert are also provided with rotating grooves for the steel wire rope to pass through.

[0007] Optionally, each of the rotating grooves is rotatably connected to a pulley that supports the sliding of the wire rope.

[0008] Optionally, the locking mechanism includes a pair of cylinders that are fixedly connected to a pair of synchronous switches inside the base. The base also has a pair of anti-rotation grooves corresponding to the cylinders. The anti-rotation grooves are connected to the mounting cavity. Each anti-rotation groove is provided with an anti-rotation clip that is fixedly connected to the piston rod of the cylinder. The output shafts at the ends of the first rotating shaft motor and the second dual-shaft motor are both fixedly fitted with gear sleeves that are locked by the anti-rotation clips.

[0009] Optionally, each of the mounting cavities is rotatably connected to a protective door, and each of the protective doors is fixedly connected to a handle.

[0010] Optionally, a mounting base plate is fixedly connected to the end of the base away from the base rod, and the mounting base plate is provided with a plurality of fixing bolts distributed in a circumferential array.

[0011] Optionally, the outer wall of the base is fixedly connected with a plurality of support sleeves that are slidably engaged with the connecting rod.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a base, motor, wire rope, and pole to create a height-adjustable drone take-off and landing platform. The motor drives a winding wheel to raise and lower the wire rope, which in turn extends and retracts the pole to adjust the platform's height. This adjustable height design allows the platform to take off and land above vegetation, avoiding ground obstacles and pollution, improving take-off and landing stability and operational efficiency. Furthermore, the adjustable height lowers the platform, solving the problem of inconvenient high-altitude installation and maintenance in traditional methods. Attached Figure Description

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model proposes a height-adjustable drone take-off and landing platform, including a base 1 and a take-off and landing platform 5. The take-off and landing platform 5 is equipped with multiple mechanisms working together to achieve drone take-off and landing. Among them, the support and positioning mechanism uses a high-strength frame and limiting baffles, combined with visual markings or lidar positioning devices on the platform surface, to ensure precise drone docking; the buffer and shock absorption mechanism uses elastic elements such as springs and rubber pads to absorb landing impact and protect the drone; the windproof and anti-slip mechanism is equipped with windproof railings, anti-slip coatings, and anti-overturning locking devices to resist strong winds at high altitudes and prevent the drone from deviating or overturning; the automatic docking and charging mechanism can automatically align with the charging contacts to replenish battery power when the drone lands; and the status monitoring sensor provides real-time feedback on the platform's levelness and pressure data to ensure safe take-off and landing. These mechanisms, through the cooperation of mechanical structures and sensors, enable the drone to take off, land, and remain stationary in high-altitude environments. Multiple support sleeves 7 are fixedly connected to the outer wall of the base 1, which slidably engage with the connecting rod 17. The support sleeves 7 provide support and guidance for the connecting rod 17, reducing its shaking during rotation and ensuring smooth rotation of the winding wheel 18. The top of the base 1 is fixedly connected to the bottom rod 2, which serves as the support base for the first insertion rod 3 and the second insertion rod 4. The bottom rod 2 has a rotating groove 231 and a through hole 233 at its end for the wire rope 234 to pass through and be guided.

[0027] Among them, such as Figures 1 to 2As shown, a first insert rod 3 and a second insert rod 4 are sequentially installed on the top of the base rod 2. The first insert rod 3 is sleeved on the top of the base rod 2 and can extend and retract along the base rod 2. Its end has a rotating groove 231 and a through hole 233. A steel wire rope 234 passes through and drives it to extend or shorten, thereby supporting and adjusting the height of the lifting platform 5. The second insert rod 4 is sleeved on top of the first insert rod 3, and its top end is fixedly connected to the lifting platform 5. It moves with the extension and retraction of the first insert rod 3, jointly supporting the lifting platform 5 and achieving height adjustment. The top end of the second insert rod 4 is fixedly connected to the lifting platform 5. One end of the base rod 2 and the first insert rod 3 is provided with a steel wire rope 234, which, when taut, allows the first insert rod 3 and the second insert rod 4 to extend. The steel wire rope 234 passes around a pulley 232, through the through hole 233, and its two ends are fixedly connected to a winding wheel 18. Through the winding and unwinding action of the winding wheel 18, the first insert rod 3 and the second insert rod 4 are pulled to extend or shorten, driving the lifting platform 5 to rise and fall.

[0028] Secondly, such as Figures 2 to 3 As shown, the base 1 is equipped with a rope winding mechanism that drives the tension of the wire rope 234. The rope winding mechanism includes a pair of mounting cavities 101 within the base 1. The mounting cavities 101 provide mounting space for the components of the first rotating shaft motor 11 and the second dual-axis motor 12, allowing the components to be arranged in an orderly manner. The first rotating shaft motor 11 is installed in one mounting cavity 101, and the second dual-axis motor 12 is installed in the other mounting cavity 101. The first rotating shaft motor 11 and the second dual-axis motor 12 work together to ensure that the wire rope 234 is wound and unwound synchronously, enabling the lifting platform 5 to rise and fall smoothly. The output shafts at both ends of the first rotating shaft motor 11 and the second dual-axis motor 12 are fixedly connected to a pair of movable connecting rods 17 that penetrate the base 1. The two ends of the connecting rods 17 are respectively connected to the motor output shaft and the winding wheel 18, transmitting motor torque and driving the winding wheel 18 to rotate. At the same time, they slide and engage with the support sleeve 7 to ensure the stability of the rotation process. One pair of shorter reels connected to the output shaft of the first rotating shaft motor 11, and the other pair connected to the output shaft of the second dual-shaft motor 12, are designed to ensure smooth transmission between the winding reels 18 and the wire rope 234, preventing the winding reels 18 on the first rotating shaft motor 11 and the second dual-shaft motor 12 from obstructing the operation. The end of the connecting rod 17 furthest from the first rotating shaft motor 11 and the second dual-shaft motor 12 is fixedly connected to a winding reel 18. Both ends of the winding reel 18 are equipped with baffles to ensure that the wire rope 234 can be engaged in the middle of the winding reel 18 after winding, preventing it from coming off. The winding reels 18 are fixedly connected to the corresponding ends of the wire rope 234.

[0029] Furthermore, the first shaft motor 11 and the second dual-axis motor 12 are dual-axis motors, which are special motors with output shafts designed to extend from both ends of the motor body. Both ends of the shaft can drive the load independently or synchronously. Compared to a single-axis motor (which outputs power from only one end), a dual-axis motor can drive two different mechanical systems simultaneously from the same power source, simplifying the transmission structure. It is often used in scenarios requiring synchronous action or bidirectional output.

[0030] In addition, such as Figures 1 to 2 As shown, both the first insertion rod 3 and the second insertion rod 4 have through holes 233 at their ends for the steel wire rope 234 to pass through. The through holes 233 allow the steel wire rope 234 to pull the insertion rods to extend or retract, thus adjusting the height of the lifting platform 5. The ends of the base rod 2 and the first insertion rod 3 also have rotating grooves 231 for the steel wire rope 234 to pass through. Inside each rotating groove 231, pulleys 232 are rotatably connected to support the sliding of the steel wire rope 234. The pulleys 232 support the steel wire rope 234 and make its sliding more flexible, reducing frictional loss between the steel wire rope 234 and the groove wall, and ensuring smooth lifting and lowering of the lifting platform 5.

[0031] It is worth noting that, such as Figures 3 to 4 As shown, a locking mechanism is installed inside the base 1 to prevent the rope mechanism from rotating. The locking mechanism includes a pair of cylinders 14 fixedly connected to a pair of synchronous switches inside the base 1. The piston rod of the cylinder 14 is connected to an anti-rotation locking strip 16. Through telescopic movement, the anti-rotation locking strip 16 is pushed into or out of the gear sleeve 13, thereby locking and unlocking the rope mechanism. The base 1 also has a pair of anti-rotation grooves 15 corresponding to the cylinders 14. The anti-rotation grooves 15 communicate with the mounting cavity 101, providing guidance for the movement of the anti-rotation locking strip 16 and ensuring its accurate engagement with the gear sleeve 13. The anti-rotation grooves 15 are connected to the mounting cavity 101, and each anti-rotation groove 15 has an anti-rotation locking strip 16 fixedly connected to the piston rod of the cylinder 14. Driven by the cylinder 14, the anti-rotation locking strip 16 moves along the anti-rotation groove 15 and engages in the tooth groove of the gear sleeve 13, preventing the motor output shaft from rotating and locking the height of the lifting platform 5. The output shafts at the ends of the first rotating shaft motor 11 and the second dual-shaft motor 12 are both fixedly fitted with gear sleeves 13 that are locked by anti-rotation clips 16. The gear sleeves 13 cooperate with the anti-rotation clips 16. When the cylinder 14 pushes the anti-rotation clips 16 into the gear sleeves 13, the motor output shaft is locked to prevent the height of the lifting platform 5 from changing.

[0032] Furthermore, such as Figures 1 to 2 As shown, each mounting cavity 101 is rotatably connected to a protective door 19. The protective door 19 is rotatably connected within the mounting cavity 101 to shield and protect the motor components inside, preventing dust and debris from entering. Each door has a handle for easy opening and closing. Each protective door 19 is fixedly connected to a handle. When the wire rope 234 is taut, the end of the second insert rod 4 inserted into the first insert rod 3 will have an excess end that cannot be dislodged. This ensures stable lifting and lowering of the second insert rod 4 within the first insert rod 3. The end of the first insert rod 3 inserted into the base rod 2 follows the same principle.

[0033] Furthermore, such as Figures 1 to 2As shown, a mounting base plate 6 is fixedly connected to the end of the base 1 away from the base rod 2. The mounting base plate 6 is fixedly connected to the end of the base 1 away from the base rod 2, and has multiple fixing bolts 61 for fixing the base 1 to the ground or other supporting surface to ensure the overall stability of the lifting platform. The mounting base plate 6 has multiple fixing bolts 61 arranged in a circumferential array. The fixing bolts 61 pass through the mounting base plate 6 and connect to the ground or supporting surface to fix the base 1 and prevent the lifting platform from moving.

[0034] In this embodiment, when using a height-adjustable UAV take-off and landing platform, the first rotating shaft motor 11 and the second dual-axis motor 12 are activated. Their output shafts drive the corresponding connecting rods 17 to rotate, thereby causing the winding wheel 18 to wind up or release the wire rope 234. When the wire rope 234 is taut, it pulls the first insert rod 3 and the second insert rod 4 to extend, causing the take-off and landing platform 5 to rise; when it is relaxed, the take-off and landing platform 5 descends under the action of gravity. After adjusting to the target height, the cylinder 14 is activated, and its piston rod pushes the anti-rotation clip 16 to engage with the gear sleeve 13, locking the rope winding mechanism and preventing the height of the take-off and landing platform 5 from changing. The support sleeve 7 guides the connecting rod 17 to slide, the mounting base plate 6 fixes the base 1 with fixing bolts 61, and the pulley 232 supports the sliding of the wire rope 234 to reduce friction.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
