Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically a rapid docking device for water tanks of fire-fighting UAVs. Background Technology

[0002] Current firefighting methods primarily rely on manual spraying, which is inefficient, costly, and involves high risks and complex operations, especially at heights. With rapid technological advancements, drones are becoming increasingly common, and firefighting infrastructure is constantly improving. Dedicated firefighting drones, equipped with intelligent controls, replace manual spraying, significantly reducing the labor demand in firefighting operations.

[0003] However, in existing firefighting drones, the water tanks used to hold liquids are mostly fixed by threaded connections or mechanical fasteners. This process is time-consuming, hinders rapid water intake, and delays firefighting opportunities.

[0004] Therefore, this application provides a quick docking device for water tanks of fire-fighting drones to solve the above problems. Utility Model Content

[0005] This application provides a quick docking device for water tanks of fire-fighting drones, which aims to solve the problems of inconvenience in the existing docking and fixing methods for water tanks of fire-fighting drones mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a quick docking device for a fire-fighting drone water tank, comprising a bracket installed for fixing to the drone equipment, a locking mechanism disposed on the bracket for quick docking and fixing to the water tank body, and a controller connected to the drone system terminal for controlling the operation of the locking mechanism. At least four handles with a U-shaped design are fixedly installed on the water tank body, arranged symmetrically in pairs; The locking mechanism includes a servo motor fixedly mounted on the hanger and electrically connected to the control terminal of the controller. The output end of the servo motor is driven by a chain drive system to a drive rod that is rotatably connected to the hanger. The two ends of the drive rod are driven by a worm gear drive system to two adjusting rods that are rotatably connected to the hanger. Two bidirectional lead screws are fixedly mounted at both ends of the two adjusting rods. Two symmetrically distributed L-shaped locking blocks are screwed onto the bidirectional lead screws. The locking blocks are inserted into the handle. In this way, when in use, the water tank, whether full or empty, is placed on the ground with the handle facing upwards. The drone is then controlled to fly above the water tank. The drone is mounted on a frame above the water tank. The drone is then positioned so that the retracted locking blocks align with the handle and insert. The controller then activates the servo motor, which, through a chain drive system, controls the rotation of the drive rod. The drive rod, through a worm gear drive system, controls the synchronous rotation of two adjusting rods, thereby driving the bidirectional lead screws on the adjusting rods to move synchronously. This causes the locking blocks to move in opposite directions, opening up two adjacent locking blocks and locking the handle, thus quickly connecting and fixing the water tank. This eliminates the need for manual adjustment of screws or mechanical fasteners, effectively improving the fixing speed and enhancing fire extinguishing efficiency.

[0007] Preferably, in order to drive the drive rod, the chain drive system includes a first sprocket fixedly mounted on the output end of the servo motor and a second sprocket fixedly mounted on the drive rod. A chain is fitted on the first sprocket and the second sprocket, thereby precisely controlling the rotation of the drive rod, which is stable and reliable.

[0008] Preferably, in order to protect the motor, a cover plate is fixedly installed on the hanger. The cover plate has through holes adapted to the chain. The servo motor is fixedly installed on the cover plate, and the chain passes through the through holes to facilitate maintenance and heat dissipation of the servo motor.

[0009] Preferably, for synchronous operation, the worm gear transmission system includes two worms with the same thread direction fixedly installed at both ends of the drive rod, and worm wheels that are adapted to the worms fixedly installed on two adjusting rods. The worms and worm wheels mesh, and the force received at each clamp is uniform and stable, improving the docking efficiency.

[0010] Preferably, in order to reduce wear and tear, a sealing plate is fixedly installed on the hanger on the side opposite to the cover plate, and the drive rod and adjusting rod are rotatably installed between the cover plate and the sealing plate to reduce wear and corrosion and improve the service life of the equipment.

[0011] Preferably, for stable operation, a limiting groove adapted to the locking block is provided between the sealing plate and the hanger. The locking block is set through the limiting groove to prevent rotation and ensure stable insertion of the handle.

[0012] Preferably, for ease of installation, a connecting rod is fixedly installed on the cover plate of the hanger, a connecting piece is fixedly installed on the connecting rod, and a fixed long groove is opened on the connecting piece to adapt to multiple models of drone frames, thereby improving the applicability of the equipment.

[0013] This docking device involves placing a full or empty water tank on the ground with the handle facing upwards. A drone is then controlled to fly above the tank and mounted on a frame. The drone's orientation is adjusted so that the retracted locking blocks align with the handle and insert. A servo motor is then activated via a chain drive system, which in turn drives a drive rod through a worm gear transmission system. This drive rod, in turn, controls two adjusting rods to rotate synchronously, causing the bidirectional lead screws on the adjusting rods to move synchronously. This causes the locking blocks to move in opposite directions, unfolding two adjacent blocks and locking the handle, thus quickly docking and securing the water tank. This method eliminates the need for manual screw adjustments or mechanical fasteners, effectively increasing the docking speed and firefighting efficiency.

[0014] This docking device, when installing the hanger, connects with the pre-drilled holes on the drone frame through a universal fixed long slot, adapting to multiple drone frame models and expanding the applicability of the equipment. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Example 1 This embodiment provides a rapid docking device for water tanks of fire-fighting drones, such as... Figure 1-5 As shown, the docking device includes a bracket 1 installed for fixing to the drone equipment, a locking mechanism 3 mounted on the bracket 1 for quick docking and fixing to the water tank body 2, and a controller 4 connected to the drone system terminal for controlling the operation of the locking mechanism 3. At least four handles 21, arranged in a U-shape and symmetrically distributed in pairs, are fixedly installed on the water tank body 2. The locking mechanism 3 includes a servo motor 31 that is fixedly installed on the hanger 1 and electrically connected to the control terminal of the controller 4. The output end of the servo motor 31 is connected to a drive rod 33 that is rotatably connected to the hanger 1 via a chain drive system 32. The two ends of the drive rod 33 are connected to two adjusting rods 35 that are rotatably connected to the hanger 1 via a worm gear drive system 34. Two bidirectional lead screws 36 are fixedly installed at both ends of the two adjusting rods 35. Two symmetrically distributed L-shaped locking blocks 37 are screwed onto the bidirectional lead screws 36. The locking blocks 37 are inserted into the handle 21.

[0019] In use, place the water tank body 2, which is full or empty, on the ground with the handle 21 facing upwards. Control the drone to fly above the water tank body 2. The drone is mounted on the water tank body 2 via a frame. Control the drone to adjust its position so that the retracted locking block 37 is aligned with the handle 21 and inserted. Then, the servo motor 31 is started by the controller 4. The servo motor 31 controls the drive rod 33 to rotate through the chain drive system 32. The drive rod 33 controls the two adjusting rods 35 to rotate synchronously through the worm gear drive system 34, thereby driving the bidirectional lead screw 36 on the adjusting rod 35 to move synchronously. This causes the locking blocks 37 to move in opposite directions synchronously, so that the two adjacent locking blocks 37 unfold and lock the handle 21, completing the quick docking and fixing of the water tank body 2. The water tank is docked and fixed without the need for manual adjustment of screws or mechanical fixing buckles, which effectively improves the fixing speed and fire extinguishing efficiency.

[0020] Specifically, the chain drive system 32 includes a first sprocket 321 fixedly mounted on the output end of the servo motor 31 and a second sprocket 322 fixedly mounted on the drive rod 33, with a chain 323 sleeved on the first sprocket 321 and the second sprocket 322.

[0021] In use, the servo motor 31 drives the first sprocket 321 to rotate through the output end. The first sprocket 321 drives the second sprocket 322 to rotate through the chain 323. The second sprocket 322 drives the drive rod 33 to rotate, thereby precisely controlling the rotation of the drive rod 33, which is stable and reliable.

[0022] More specifically, a cover plate 11 is fixedly installed on the hanger 1, and a through hole 12 adapted to the chain 323 is opened on the cover plate 11. The servo motor 31 is fixedly installed on the cover plate 11, and the chain 323 is set through the through hole 12.

[0023] In use, the top of the hanger 1 is covered by the cover plate 11 to support the servo motor 31. The chain 323 is placed outside the hanger 1 and passes through the cover plate 11 through the through hole 12 to connect with the second sprocket 322, which facilitates the maintenance and heat dissipation of the servo motor 31.

[0024] Furthermore, the worm gear transmission system 34 includes two worms 341 with the same thread direction fixedly installed at both ends of the drive rod 33, and worm wheels 342 that are fixedly installed on two adjusting rods 35 and adapted to the worms 341, with the worms 341 meshing with the worm wheels 342.

[0025] In use, the drive rod 33 rotates, causing the worm gears 341 at both ends to rotate synchronously. This causes the worm gears 341 to mesh and drive the worm wheel 342 to rotate, thus completing the synchronous adjustment of the adjusting rod 35. This ensures that each locking block 37 operates synchronously, and that the force received by each locking block is uniform and stable, thereby improving docking efficiency.

[0026] Furthermore, a sealing plate 13 is fixedly installed on the hanger 1 on the side opposite to the cover plate 11, and the drive rod 33 and the adjusting rod 35 are both rotatably installed between the cover plate 11 and the sealing plate 13.

[0027] In use, the other side of the hanger 1 is blocked by the sealing plate 13, thereby protecting the drive rod 33 and the adjusting rod 35 inside, reducing wear and corrosion, and improving the service life of the equipment.

[0028] Among them, a limiting groove 14 adapted to the locking block 37 is provided between the sealing plate 13 and the hanger 1, and the locking block 37 is set through the limiting groove 14.

[0029] In use, the locking block 37 is guided and limited by the limiting groove 14 to ensure that the locking block 37 moves along the trajectory when sliding in the limiting groove 14, avoiding self-rotation and ensuring stable insertion of the handle 21.

[0030] Example 2 A connecting rod 15 is fixedly installed on the cover plate 11 on the hanger 1, and a connecting piece 16 is fixedly installed on the connecting rod 15. A fixed long groove 17 is opened on the connecting piece 16.

[0031] When using the device, the mounting bracket 1 is installed by connecting it to the pre-drilled holes on the drone frame through the universal fixed long slot 17, which is compatible with multiple drone frames and improves the applicability of the equipment.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
