Description

Technical Field

[0001] This invention relates to the field of airborne flame spraying technology, and more specifically, to a lightweight airborne flame rack with an attitude adaptive adjustment mechanism and its application. Background Technology

[0002] The lightweight airborne flame strip pyrotechnic rack is a high-efficiency load system designed specifically for aviation platforms such as drones. Its core feature is that it significantly reduces its own weight while ensuring load-bearing strength and rigidity, thereby effectively extending the platform's endurance and improving flight performance. The overall design is compact and has low air resistance. It is mainly used in artificial weather modification operations, such as rain enhancement and hail suppression, and is a key device for achieving efficient and automated catalytic seeding tasks.

[0003] Patent application number CN202421012834.X discloses an airborne flame spreader for unmanned aerial vehicles (UAVs). The UAV includes an upper frame located below the wings on both sides. A first connecting rod is rotatably connected to one bottom side of the upper frame, and a second connecting rod is rotatably connected to the other bottom side of the upper frame. A lower frame is located at the bottom of the first and second connecting rods. By setting up the upper frame, the first connecting rod, the second connecting rod, the lower frame, and the first locking mechanism, stability, adjustability, and ease of operation are combined, providing an efficient and reliable solution for spreading operations.

[0004] However, existing airborne flame strip pyrotechnic racks typically employ fixed or single-function structural designs, resulting in drawbacks such as bulky structures, poor aerodynamic performance, and fixed functions. Their rack structures are mostly rigid connections that cannot be retracted, leading to high drag and energy consumption for UAVs. They are also prone to swaying under airflow disturbances, affecting operational stability. Furthermore, existing racks often lack the ability to adjust the flame strip angle synchronously during deployment, making it impossible to achieve precise catalyst delivery to cloud structures, thus limiting the effectiveness and adaptability of weather modification operations.

[0005] In view of this, we propose a lightweight airborne flame bar mount with an attitude adaptive adjustment mechanism and its application. Summary of the Invention

[0006] The purpose of this invention is to provide a lightweight airborne flame strip rack with an attitude adaptive adjustment mechanism and its application. Through a telescopic movable frame structure, combined with a front fairing that can be sequentially spliced, the overall lightweight design and streamlined shape of the telescopic rack are achieved, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A lightweight airborne flame strip pylon mount with an attitude adaptive adjustment mechanism and its application, comprising a drone and a loading mechanism disposed under the wing of the drone, the loading mechanism comprising a fixed platform and a drive and a telescopic mount disposed inside the fixed platform;

[0009] The driver includes a pair of motors arranged in parallel front and rear, and a lead screw and a rotating shaft driven by the two motors respectively.

[0010] The telescopic rack includes several horizontally parallel movable frames, frame strips set on the outer wall of the movable frames, a pair of X-shaped intersecting connecting rods hinged between adjacent movable frames, a placement frame that rotates on the bottom surface of the movable frames, a worm gear sleeved on the end of the central shaft of the placement frame, and a worm gear that meshes with the worm gear and slides on the outside of the rotating shaft.

[0011] After the lead screw rotates, it only drives the outer end of the movable frame to move to the right. Through the linkage, it causes several movable frames in the middle to move synchronously. After the rotating shaft rotates, it drives the worm to mesh with the worm wheel, thereby adjusting the fixed angle of the placement frame.

[0012] The fixed platform includes a pair of round rods located at the ends of the telescopic path of the mobile frame, a sliding plate located below the round rods, and a clamping rod that moves with the sliding plate. The ends of the round rods are provided with paddles, and the sliding plate is provided with inclined grooves.

[0013] When the movable frame extends to its maximum stroke, its outer wall presses against the round rod, causing the lever to slide along the inclined groove, which drives the slide plate to move the clamping rod and lock the telescopic hanger.

[0014] In the technical solution of the present invention, the fixed platform further includes connecting beams arranged parallel to each other on the left and right sides below the wing of the UAV, sliding rods snapped and fixed between a pair of connecting beams, several guide fairings regularly arranged on the front side of a pair of connecting beams, and a square frame welded and fixed to the inner wall of the guide fairing.

[0015] In the technical solution of the present invention, two through square grooves are provided on the outer wall of the connecting beam on the right side. Both connecting beams are fixedly connected to the frame at the bottom of the UAV wing by bolts. The fairing on the far left is snapped and fixed to the outer wall of the connecting beam. The longitudinal cross-sectional dimensions of the fairings increase from left to right.

[0016] In the technical solution of the present invention, the round rod is slidably connected to the outer wall of the connecting beam, the lever is integrally formed with the round rod, the slide plate is slidably connected to the inside of the connecting beam, and the clamping rod is fixedly connected to the top surface of the slide plate by bolts.

[0017] In the technical solution of the present invention, the longitudinal section of the round rod is T-shaped and a spring is sleeved on the outside. The elastic force provided by the spring pushes the round rod to move away from the slide plate.

[0018] The above configuration allows the telescopic rack to maintain a low drag state during flight, while mechanical locking ensures stability during operation, thus balancing aerodynamic performance and operational reliability.

[0019] In the technical solution of the present invention, the motor is fixedly connected to the inner wall of the connecting beam on the left side by screws, the lead screw and the rotating shaft are coaxially connected to the output shafts of the front and rear motors respectively, and the ends of the lead screw and the rotating shaft are rotatably connected to the outer wall of the connecting beam on the right side.

[0020] This setting enables independent control of telescopic extension and angle adjustment, providing a precise driving basis for subsequent attitude adaptive adjustment.

[0021] In the technical solution of the present invention, the telescopic bracket further includes a frame strip welded and fixed to the outer wall of the mobile frame, a fixed cover fixedly connected to the top surface of the mobile frame by screws, and brackets welded and fixed to the front and rear ends of the top surface of the mobile frame. The ends of the mobile frame are fixedly connected to the inside of the square frame by bolts.

[0022] In the technical solution of the present invention, a slot with through-hole is provided on the outer wall of the movable frame located at the right end. A frame strip is welded and fixed on the outer wall of the movable frame. The bracket at the front end of the top of the movable frame located at the right end is threadedly connected to the lead screw. The rear end of the connecting rod is rotatably connected to the protruding frame on the outer wall of the movable frame, and the front end of the connecting rod is slidably connected to the inside of the frame strip.

[0023] In the technical solution of the present invention, the worm gear is rotatably connected to the inner wall of the fixed cover, and the worm gear has a through hole that runs through the left and right sides and whose size is adapted to the rotating shaft. The worm wheel is fixedly connected to the end position of the central shaft of the placement frame by a snap pin.

[0024] The aforementioned placement rack expands the working range of the flame strip, and the angle of the placement rack can be adjusted through the worm gear and worm wheel, ensuring the accuracy of catalyst delivery.

[0025] On the other hand, the present invention also provides an application of a lightweight airborne flame strip holder with an attitude adaptive adjustment mechanism, which is used in weather modification operations based on an unmanned aerial vehicle platform.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This lightweight airborne flame strip pylon with attitude adaptive adjustment mechanism and its application, through a telescopic movable frame structure, combined with a front fairing that can be sequentially spliced, achieves a lightweight design and streamlined shape for the telescopic pylon. The fairing allows the telescopic pylon to be fully retracted, maintaining a low-drag state during UAV flight. When the telescopic pylon is fully extended, a linkage locking mechanism between the round rod and the clamping rod achieves mechanical locking of the telescopic pylon, ensuring the structural rigidity and stability of the telescopic pylon in the operational deployment state, effectively avoiding structural swaying that may be caused by airflow disturbances, and providing a platform foundation for subsequent operations.

[0028] 2. The lightweight airborne flame strip holder with attitude adaptive adjustment mechanism and its application utilize a worm gear that can slide on a rotating shaft. This ensures that the worm gear remains effectively engaged with the worm wheel while the moving frame is unfolding or retracting. When the motor drives the rotating shaft to rotate the worm gear, the fixed angle of the placement frame can be precisely adjusted via the worm wheel. This allows for control of the flame strip's spray direction while it is being deployed, enabling the catalyst to be precisely aimed at the core operating area based on the cloud structure. This significantly improves the targeting and effectiveness of weather modification operations. Attached Figure Description

[0044] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0045] Please see Figures 1-7 As shown, this embodiment provides the following technical solution:

[0046] A lightweight airborne flame strip pylon with an attitude adaptive adjustment mechanism is used in weather modification operations based on a drone platform. The pylon includes a drone 100 and a loading mechanism 200 located under the wing of the drone 100.

[0047] Specifically, the loading mechanism 200 includes a fixed platform 210 and a drive unit 220 and a telescopic hanger 230 disposed inside the fixed platform 210.

[0048] Furthermore, the fixed platform 210 includes a pair of round rods 215, a slide plate 217 located below the round rods, and a clamping rod 218 that moves with the slide plate 217. The ends of the round rods 215 are provided with a lever 2150, and the slide plate is provided with a slanted groove 2170.

[0049] Furthermore, the fixed platform 210 also includes connecting beams 211 arranged parallel to each other on the left and right sides below the wings of the UAV 100, sliding rods 212 snapped and fixed between a pair of connecting beams 211, several fairings 213 regularly arranged on the front side of a pair of connecting beams 211, and a frame 214 welded and fixed to the inner wall of the fairings 213.

[0050] Furthermore, two through square grooves are provided on the outer wall of the connecting beam 211 on the right side. Both connecting beams 211 are fixedly connected to the frame at the bottom of the wing of the UAV 100 by bolts. The fairing 213 on the far left is snapped and fixed to the outer wall of the connecting beam 211. The longitudinal cross-sectional dimensions of several fairings 213 increase from left to right.

[0051] Furthermore, the round rod 215 is slidably connected to the outer wall of the connecting beam 211, the lever 2150 is integrally formed with the round rod 215, the slide plate 217 is slidably connected to the inside of the connecting beam 211, and the clamping rod 218 is fixedly connected to the top surface of the slide plate 217 by bolts.

[0052] Furthermore, the longitudinal section of the round rod 215 is T-shaped and a spring 216 is also sleeved on the outside. The elastic force provided by the spring 216 pushes the round rod 215 to move away from the slide plate 217.

[0053] Furthermore, the connecting beam 211 ensures the stability of the connection between the fixed platform 210 and the UAV 100. Simultaneously, the connecting beam 211 on the left provides a placement area for the internal structure of the actuator 220. The slide bar 212 provides a sliding area for the internal structure of the telescopic rack 230. During UAV takeoff, the sequentially assembled fairing 213 forms a streamlined structure, reducing the additional aerodynamic drag caused by the addition of the loading mechanism 200 and the flame strip, thereby avoiding decreased flight stability and increased energy consumption. The frame 214 provides a fixed base point for the structure within the telescopic rack 230. The round rod 215 causes the lever 2150 to slide along the inclined groove 2170, driving the slide plate 217 to move the clamping rod 218 to lock the telescopic hanger 230. After the telescopic hanger 230 retracts, the round rod 215 returns to its original position under the action of the spring 216. This setting allows the telescopic hanger 230 to maintain a low drag state during flight, and can also ensure stability through mechanical locking during operation, taking into account both aerodynamic performance and operational reliability. By integrating multiple independent and fixed attachment points into a telescopic hanger 230 that is retractable and shares a main structure, the number and weight of structural components are reduced.

[0054] Please see Figures 1-2 As shown, in this embodiment, the driver 220 includes a pair of motors 221 arranged in parallel front to back, and a lead screw 222 and a rotating shaft 223 driven by the two motors 221 respectively.

[0055] Specifically, motor 221 is fixedly connected to the inner wall of the left connecting beam 211 by screws, and lead screw 222 and rotating shaft 223 are coaxially connected to the output shafts of the front and rear motors 221 respectively. The ends of lead screw 222 and rotating shaft 223 are rotatably connected to the outer wall of the right connecting beam 211.

[0056] Furthermore, after the two motors 221 are started, they drive the lead screw 222 and the rotating shaft 223 to rotate respectively. This setting realizes independent control of telescopic extension and angle adjustment, providing a precise driving basis for subsequent attitude adaptive adjustment.

[0057] Please see Figures 8-12 As shown, in this embodiment, the telescopic bracket 230 includes several horizontally parallel movable frames 231, frame strips 232 disposed on the outer wall of the movable frames 231, a pair of X-shaped connecting rods 235 hinged between adjacent movable frames 231, a placement frame 238 rotatably mounted on the bottom surface of the movable frames 231, a worm gear 237 sleeved on the end of the central shaft of the placement frame 238, and a worm 236 meshing with the worm gear 237 and sliding on the outside of the rotating shaft 223. After the lead screw 222 rotates, it only drives the movable frame 231 at the outer end to move to the right, and through the connecting rods 235, it drives the several movable frames 231 located in the middle to move synchronously. After the rotating shaft 223 rotates, it drives the worm 236 to mesh with the worm gear 237, thereby adjusting the fixed angle of the placement frame 238.

[0058] Specifically, the telescopic bracket 230 also includes a frame strip 232 welded and fixed to the outer wall of the movable frame 231, a fixed cover 233 fixedly connected to the top surface of the movable frame 231 by screws, and a bracket 234 welded and fixed to the front and rear ends of the top surface of the movable frame 231. The ends of the movable frame 231 are fixedly connected to the inside of the square frame 214 by bolts.

[0059] Furthermore, a through slot 2310 is provided on the outer wall of the movable frame 231 located at the right end. A frame strip 232 is welded and fixed on the outer wall of the movable frame 231. The bracket 234 at the front end of the top surface of the movable frame 231 located at the right end is threadedly connected to the lead screw 222. The brackets 234 at the front end of the top surface of the remaining movable frames 231 are all slidably connected to the lead screw 222. The brackets 234 at the rear end of the top surface of the remaining movable frames 231 are all slidably connected to the slide rod 212. The rear end of the connecting rod 235 is rotatably connected to the protruding frame on the outer wall of the movable frame 231, and the front end of the connecting rod 235 is slidably connected to the inside of the frame strip 232.

[0060] Furthermore, the worm 236 is rotatably connected to the inner wall of the fixed cover 233. The worm 236 has a through hole that runs through the left and right sides and whose size is adapted to the rotating shaft 223. The worm wheel 237 is fixedly connected to the end of the central shaft of the placement frame 238 by a snap pin.

[0061] Furthermore, after the lead screw 222 rotates, it drives the movable frame 231 at the outer end to move to the right. Through the X-shaped cross-hinged connecting rod 235, several movable frames 231 located in the middle are simultaneously deployed, causing the originally retracted and stacked placement frames 238 to be arranged linearly, expanding the deployment range of the flame strip. After the rotating shaft 223 rotates, it drives multiple worm gears 236 to rotate. After the worm gears 236 mesh with the worm wheel 237, they drive the placement frames 238 to rotate around their central axis, thereby precisely adjusting the spray angle of the flame strip, so that the flame strip is aimed at the target area in the cloud, improving the accuracy and effectiveness of catalyst delivery. This setting expands the working range of the flame strip by deploying the placement frames 238, and the angle adjustment of the placement frames 238 is achieved through the worm gears 236 and the worm wheel 237, ensuring the accuracy of catalyst delivery.

[0062] When using the lightweight airborne flame strip rack with attitude adaptive adjustment mechanism of the present invention, the operator first inserts the flame strips into the placement rack 238 in the loading mechanism 200, and after ensuring that the flame strips are securely fixed, controls the UAV 100 to take off and move toward the target area in the clouds with high supercooled water content and suitable for catalysis.

[0063] During the takeoff of the UAV, several movable frames 231 in the loading mechanism 200 are in a retracted state. The flow guide 213, which is sequentially spliced ​​on the front side of the several movable frames 231, forms a streamlined structure, reducing the additional aerodynamic drag caused by the addition of the loading mechanism 200 and the flame strip, thereby avoiding a decrease in flight stability and an increase in energy consumption.

[0064] Next, when the UAV 100 moves to the target area, the motor 221 located at the front of the driver 220 is started first, which drives the lead screw 222 to rotate, thereby driving the outer end of the moving frame 231 to move to the right. Through the X-shaped cross-hinged connecting rod 235, the moving frames 231 located in the middle are simultaneously unfolded, so that the original retracted and stacked placement frames 238 are arranged in a linear unfolding pattern, expanding the deployment range of the flame strips.

[0065] At this time, the rightmost movable frame 231 extends to its maximum stroke, and its outer wall presses against the round rod 215 in the fixed platform 210, causing the paddle block 2150, which is integrally formed with the round rod 215, to slide along the inclined groove 2170 on the slide plate 217. This drives the slide plate 217 to move the clamping rod 218, so that the clamping rod 218, which extends into the slot 2310, is in close contact with the slot wall, thereby achieving mechanical locking of the telescopic hanger 230 and ensuring the stability of the hanger during operation.

[0066] Subsequently, based on the data collected by the cloud particle high-resolution imaging device carried by the UAV, combined with airflow analysis and particle concentration algorithm, the area with high supercooled water content in the cloud is identified. The motor 221 located on the rear side of the driver 220 is started, which drives the rotating shaft 223 to rotate synchronously, thereby driving multiple worm gears 236 to rotate. After the worm gears 236 mesh with the worm wheel 237, they drive the placement frame 238 to rotate around its central axis, thereby precisely adjusting the spray angle of the flame strip so that the flame strip is aimed at the target area in the cloud, improving the accuracy of catalyst delivery and the operational effect.

[0067] After the operation is completed, during the return of the UAV, the two motors 221 in the control driver 220 rotate in opposite directions, causing the telescopic bracket 230 to gradually retract. At the same time, the round rod 215 is reset under the action of the spring 216, the clamping rod 218 disengages from the slot 2310, and the placement frame 238 returns to its initial compact state, which facilitates the safe landing of the UAV 100.

[0068] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
