[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Referring to Figures 1 and 2, one embodiment of this utility model provides a river rescue drone, including a fixed plate a1, which serves as a core support component, providing stable support for the entire drone. The top of the fixed plate a1 is fixedly connected to the drone shell 2. Inside the drone shell 2 are motors a3 and b4, both high-performance brushless DC motors with advantages such as high efficiency, low noise, and long lifespan. The bottoms of motors a3 and b4 are fixedly connected to the top of the fixed plate a1, providing a power source for subsequent angle adjustment. A connecting column a5 is fixedly connected to the drive end of motor a3. The connecting column a5 is made of high-strength stainless steel to ensure stability and durability during transmission. The connecting column a5 is externally rotatably connected to the inside of the fixed plate a1, ensuring smooth rotation. A positive... Gear A7, specifically the spur gear A7, is made of high-quality alloy steel and precision-machined, resulting in high tooth profile accuracy and smooth transmission, effectively reducing energy loss during transmission. A connecting column B6, also made of high-strength stainless steel, is fixedly connected to the drive end of motor B4. Connecting column B6 is externally rotatably connected to the inside of fixed plate A1, ensuring stable rotation. A spur gear B8, made of the same material as spur gear A7, is fixedly connected to the outside of connecting column B6, possessing high precision and durability, providing reliable support for subsequent gear transmission. A fixed column A9, made of solid stainless steel, is fixedly connected to the bottom of fixed plate A1, offering high strength and the ability to withstand [damage / constraints]. With a large torque, the fixed column a9 is externally rotatably connected to an angle adjustment component. This component allows for flexible adjustment of the gripper assembly's angle to adapt to different rescue scenarios. A gripper assembly is fixed to the bottom of the angle adjustment component for grasping rescue supplies. The angle adjustment component includes a fixed column b10, which has a hollow interior and is made of aluminum alloy to reduce weight while maintaining strength. The fixed column b10 is internally rotatably connected to the outside of the fixed column a9, enabling relative rotation. A spur gear c11 is fixedly connected to the outside of the fixed column b10, meshing with spur gear a7. When motor a3 drives connecting column a5 to rotate spur gear a7... The spur gear c11 rotates, which in turn drives the fixed column b10 to rotate around the fixed column a9, initially adjusting the angle of the gripper assembly. The bottom of the spur gear c11 is provided with a spur gear d12, which is made of the same high-quality alloy steel as the spur gear a7. The bottom of the spur gear d12 is fixedly connected to a bevel gear a13. The rotation of the spur gear d12 drives the bevel gear a13 to rotate. Both the spur gear d12 and the bevel gear a13 are rotatably connected to the outside of the fixed column b10. The spur gear d12 meshes with the spur gear b8. When the motor b4 drives the connecting column b6 to rotate the spur gear b8, the spur gear d12 rotates accordingly, which in turn drives the bevel gear a13 to rotate.The fixed column b10 is externally fixedly connected to the limiting column a14, which is made of stainless steel and serves as a support and positioning element. The limiting column a14 is externally fixedly connected to the bevel gear b15, which meshes with the bevel gear a13. The rotation of the bevel gear a13 drives the bevel gear b15 to rotate, which in turn drives the limiting column a14 to rotate. The limiting column a14 is externally rotatably connected to the connecting plate a16, which is made of aluminum alloy, is lightweight and has high strength. The rotation of the limiting column a14 drives the connecting plate a16 to rotate, further assisting in adjusting the angle of the gripper assembly so that the gripper assembly can be accurately aligned with the rescue target.

[0025] The gripper assembly includes a cylinder a17, which is a high-precision pneumatic actuator with advantages such as fast response and high control accuracy. The bottom of cylinder a17 is fixedly connected to the outside of connecting plate a16. A push rod a18 is slidably connected inside cylinder a17. Push rod a18 is made of high-strength stainless steel and slides smoothly. A rack a19 is fixedly connected to the bottom of push rod a18. The movement of rack a19 drives the rotation of connecting gear a20. A frame housing 23 is fixedly connected to the bottom of connecting plate a16. The frame housing 23 is made of aluminum alloy, has a robust structure, and provides protection for internal components. Two connecting gears a20 are rotatably connected inside the frame housing 23. Each connecting gear a20 is made of high-quality alloy steel. The two connecting gears a20 mesh with the rack a19 respectively. When the cylinder a17 drives the push rod a18 to move the rack a19, the two connecting gears a20 rotate synchronously. Each connecting gear a20 is fixedly connected to a connecting rod a21. The connecting rod a21 is made of high-strength aluminum alloy, which is lightweight and strong. Each connecting rod a21 is fixedly connected to a limit post b22 inside. The limit post b22 is made of stainless steel and serves as a support and positioning function. Each limit post b22 is rotatably connected to two connecting plates b25. The connecting plates b25 are made of aluminum alloy, which is lightweight and strong. The frame shell 23 has two rotatably connected internally to two connecting rods b24. The internal parts of the two connecting rods b24 are rotatably connected to the external parts of two limiting posts b22. The external parts of the limiting posts b22 are rotatably connected to the internal parts of two connecting plates b25. Through this simple linkage mechanism, when the connecting gear a20 rotates, it drives the connecting rods a21 and b24 to move, which in turn drives the connecting plate b25 to move. The bottom of the connecting plate b25 is fixedly connected to a fixing block 26. The fixing block 26 is made of rubber with a non-slip texture on the surface, which can effectively increase the friction between the fixing block and the rescue materials and ensure stable gripping. Through the coordinated work of the various components, the opening and closing action of the gripper assembly is realized, completing the gripping and release of the rescue materials.

[0026] Referring to Figures 3 and 4, a storage box 27 is fixedly connected to the bottom of the drone shell 2. This storage box 27 is made of high-strength engineering plastic, enabling long-term use in complex and variable river rescue environments, providing reliable storage space for rescue supplies. Its interior undergoes special waterproofing treatment to effectively prevent river water from seeping in and damaging supplies. A cylinder b28 is fixedly connected to the inner wall of the storage box 27. Cylinder b28 is a high-performance pneumatic actuator with fast response and stable thrust, capable of completing extension and retraction movements in a short time, providing power support for subsequent storage and release operations. The cylinder b28 has an internal sliding mechanism. A push rod b29 is dynamically connected, and the push rod b29 can slide smoothly under the drive of the cylinder b28, ensuring efficient power transmission. A rack b30 is fixedly connected to the right side of the push rod b29, and the rack b30 converts the linear motion of the push rod b29 into the rotational motion of the gear. A limit post c32 is fixedly connected to the inner wall of the storage box 27. The limit post c32 plays a supporting and positioning role, ensuring the stable rotation of subsequent components. A connecting gear b31 is rotatably connected to the outside of the limit post c32. The connecting gear b31 meshes with the rack b30. When the rack b30 moves, the connecting gear b31 will rotate around the limit post. The rotation of column c32 enables power transmission and direction conversion. Externally, the limiting column c32 is rotatably connected to a limiting rod a33, which is made of high-strength aluminum alloy, lightweight and high-strength, reducing overall weight while ensuring structural strength. Internally, the limiting rod a33 is rotatably connected to a limiting column d35, which serves as a connection and positioning element. A fixing plate b36 is fixedly connected to the limiting column d35, a key component in the storage box 27 used for closing and opening the storage space. Externally, the storage box 27 is fixedly connected to the interior of another limiting column d35, which is similar to... To provide stable support for subsequent components, the external rotatable connection of the limiting post d35 is a limiting rod b34. The limiting rod b34 and the limiting rod a33 together form a linkage mechanism, which realizes the movement of the fixed plate b36 through rotational cooperation. The external rotatable connection of the limiting rod b34 is to the outside of the fixed plate b36. When the cylinder b28 drives the push rod b29 to move the rack b30, thereby causing the connecting gear b31 to rotate, the limiting rod a33 and the limiting rod b34, through the coordinated action of the linkage mechanism, drive the fixed plate b36 to open and close within the storage box 27, thereby realizing the storage and release operation of rescue materials.

[0027] Working Principle: When this river rescue drone is in operation, motors a3 and b4 work together for angle adjustment. After motor a3 starts, its drive end drives the connecting column a5 to rotate inside the fixed plate a1. According to the gear meshing transmission principle, the rotation of spur gear a7 will drive spur gear c11 to rotate synchronously. The rotation of spur gear c11 will cause the fixed column b10 to rotate around the fixed column a9, thereby realizing the rotation of the angle adjustment component around the fixed column a9, initially adjusting the angle of the gripper component so that it can face the general rescue direction. At the same time, motor b4 starts, and its drive end drives the spur gear b8 fixed on the connecting column b6 to rotate. The rotation of spur gear b8 will drive the spur gear d12 to rotate, and drive the bevel gear a13 fixed on it to rotate. The rotation of bevel gear a13 will drive the bevel gear... Wheel B15 rotates, which in turn drives the limiting post A14 to rotate. The limiting post A14 is externally connected to the connecting plate A16. The rotation of the limiting post A14 will drive the connecting plate A16 to rotate, thereby further assisting in adjusting the angle of the gripper assembly, so that the gripper assembly can be accurately aligned with the rescue target, ensuring the accuracy of the rescue operation. When it is necessary to grab rescue materials, cylinder A17 is activated, and push rod A18 slides inside cylinder A17, driving rack A19 to move. The movement of rack A19 will drive two connecting gears A20 to rotate. The rotation of connecting gears A20 will drive connecting rod A21 and limiting post B22 to rotate. The rotation of limiting post B22 will drive connecting plate B25 and connecting rod B24 to move, ultimately causing fixed block 26 to complete the gripping action, realizing the grabbing of rescue materials for river rescue operations.

[0028] When the relevant components of storage box 27 are working, cylinder b28 is activated, and its internal push rod b29 moves, driving the fixedly connected rack b30 to move synchronously. Because rack b30 meshes with connecting gear b31 fixed outside of limit post c32 and rotatably connected to it, the movement of rack b30 causes connecting gear b31 to rotate around limit post c32, thereby driving limit rod a33 rotatably connected to limit post c32 to rotate. Limit rod a33 is connected to fixed plate b36 through limit post d35, and together with limit rod b34 rotatably connected to another limit post d35 fixed outside storage box 27, they form a linkage mechanism. The rotation of limit rod a33 drives limit rod b34 to move through the linkage mechanism, causing fixed plate b36 to move, realizing the opening and closing of storage space in storage box 27, and completing the storage and release of rescue supplies.
