Description

Technical Field

[0001] This utility model relates to the field of drone rescue equipment technology, and in particular to a drone lifebuoy continuous throwing device. Background Technology

[0002] A drone-based lifebuoy delivery system is a piece of equipment used for water rescue. It improves rescue efficiency by quickly and accurately deploying lifebuoys to the location of a person in the water. Traditional drone-based lifebuoy delivery systems typically use simple release mechanisms, relying on gravity or spring force for deployment. However, they cannot perform continuous deployments, requiring a return trip to replenish lifebuoys after each rescue, delaying rescue time. Furthermore, lifebuoys are prone to getting stuck or tangled during deployment, leading to failed deployments.

[0003] Furthermore, traditional throwing devices offer poor protection and stability, and lifebuoys may detach or be damaged during transport due to shaking. Therefore, there is an urgent need for a drone-based lifebuoy throwing device that is simple in structure, highly reliable, and supports continuous throwing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a continuous throwing device for lifebuoys for drones, which overcomes the shortcomings of the existing technology and effectively solves the problems that traditional throwing devices in the existing technology cannot achieve continuous throwing and have poor protection and stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuous life ring throwing device for drones includes a protective cylinder with a bottom shell screwed to its bottom. A limiting mechanism is provided between the protective cylinder and the bottom shell. The limiting mechanism includes a circular block, a fixed rod welded and fixed to the top of the circular block, a hanging ring rotatably connected to the top of the fixed rod, a fixed cylinder welded and fixed to the bottom of the circular block, a movable block disposed inside the fixed cylinder, a threaded rod rotatably connected to the bottom of the movable block, a ball block welded and fixed to the bottom of the threaded rod, and an internally threaded tube welded and fixed to the bottom of the fixed cylinder and screwed to the threaded rod.

[0007] After the drone, equipped with the throwing device, flies to the target area, the flight control system triggers the servo motor to start. The servo motor drives the threaded rod to rotate. Since the threaded rod is screwed to the internal threaded pipe, the movable block slides upward along the slide groove. As the movable block moves upward, the lifebuoy, no longer restrained by the ball block, slides along the inclined surface of the bottom shell towards the throwing port. When the extended ball block contacts the inclined surface of the bottom shell, it acts as a restraint before the lifebuoy slides out, ensuring that the lifebuoy is released as needed. After one throwing is completed, the servo motor reverses, driving the movable block to reset, and the next lifebuoy automatically falls into the restrained position. Repeating the above process enables continuous throwing. The structural design of the protective cylinder and the bottom shell ensures that the lifebuoy remains stable during flight and throwing, avoiding throwing failure due to external interference. The entire device achieves precise and efficient rescue operations through mechanical linkage and motor control.

[0008] Preferably, the bottom of the bottom shell is a slope, and a throwing port is provided on one side of the bottom end of the slope, which is located on one side of the annular outer wall of the bottom shell.

[0009] Preferably, the top of the protective cylinder has an opening, and the inner diameter of the opening is larger than the outer diameter of the circular block, while the inner diameter of the opening is smaller than the distance from one end of the connecting rod to the center of the circular block.

[0010] Preferably, sliders are welded and fixed on both sides of the outer annular wall of the movable block, and grooves that slide with the sliders are provided on both sides of the inner annular wall of the fixed cylinder.

[0011] Preferably, a servo motor is mounted and fixed on the top of the movable block, and the output shaft of the servo motor is connected and fixed to the top end of the threaded rod through a coupling.

[0012] Preferably, the inner diameters of the protective cylinder and the bottom shell are both adapted to the outer diameter of the lifebuoy, and the lifebuoy and the inclined surface of the bottom shell are limited and fixed by an extended ball block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This device achieves stable fixation and precise release of the lifebuoy through a limiting mechanism. The cooperation between the round block, the fixed rod, and the hanging ring allows the device to be suspended and connected to the drone, facilitating the transportation of the lifebuoy. The linkage design of the movable block and the threaded rod enables the lifebuoy to be gradually lowered and thrown by the servo motor, avoiding deviation caused by a one-time release. The inclined design of the bottom shell and the throwing port further ensure that the lifebuoy slides out in the predetermined direction, improving the throwing accuracy.

[0015] 2. This device supports continuous throwing. The inner diameter of the protective cylinder and the bottom shell is adapted to the outer diameter of the lifebuoy, which can accommodate multiple lifebuoys. Through the step-by-step release of the limiting mechanism, the drone can complete multiple rescue missions without frequent return. In addition, the sliding cooperation between the slider and the groove and the limiting effect of the ball block enhance the stability and reliability of the device, avoiding lifebuoy jamming or entanglement. The overall structure is simple, easy to maintain, and suitable for water rescue in complex environments. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] Reference Figure 1-4 A continuous life ring throwing device for drones includes a protective cylinder 1, a bottom shell 2 screwed to the bottom of the protective cylinder 1, a limiting mechanism 3 provided between the protective cylinder 1 and the bottom shell 2, the limiting mechanism 3 including a circular block 4, a fixing rod 5 welded and fixed to the top of the circular block 4, a hanging ring 6 rotatably connected to the top of the fixing rod 5, a fixing cylinder 8 welded and fixed to the bottom of the circular block 4, a movable block 9 provided in the fixing cylinder 8, a threaded rod 12 rotatably connected to the bottom of the movable block 9, a ball block 13 welded and fixed to the bottom of the threaded rod 12, and an internally threaded tube 14 welded and fixed to the bottom of the fixing cylinder 8 and screwed to the threaded rod 12;

[0024] The bottom of the bottom shell 2 is inclined, and a throwing port is provided on one side of the bottom end of the inclined surface, which is located on one side of the annular outer wall of the bottom shell 2. The inclined surface design of the bottom shell 2 allows the life ring to slide naturally towards the throwing port after release, avoiding jamming. The top of the protective cylinder 1 has an opening, the inner diameter of which is larger than the outer diameter of the circular block 4 and smaller than the distance from one end of the connecting rod 7 to the center of the circular block 4. The bottom of the protective cylinder 1 is connected to the bottom shell 2 by a thread, which is convenient for disassembly and maintenance. The opening size at the top of the protective cylinder 1 is designed to be slightly larger than the outer diameter of the circular block 4, but smaller than the extension length of the connecting rod 7, to ensure that the life ring will not fall off when it is inserted. The fixing rod 5 of the limiting mechanism 3 is rotatably connected to the hanging ring 6, so that the life ring can be freely suspended at the bottom of the drone and maintain balance. The movable block 9 has sliders 10 welded and fixed on both sides of the annular outer wall. The fixed cylinder 8 has grooves on both sides of the annular inner wall that form a sliding fit with the sliders 10.

[0025] A servo motor 11 is fixedly mounted on the top of the movable block 9. The output shaft of the servo motor 11 is connected and fixed to the top of the threaded rod 12 via a coupling. The control signal of the servo motor 11 can be remotely triggered by the UAV flight control system to achieve automated throwing. The threaded connection design between the threaded rod 12 and the internal threaded tube 14 ensures the movement accuracy of the movable block 9 and avoids misoperation. The inner diameters of the protective cylinder 1 and the bottom shell 2 are both adapted to the outer diameter of the lifebuoy. The inclined surfaces of the lifebuoy and the bottom shell 2 are limited and fixed by an extended ball block 13. The inside of the fixed cylinder 8 The movable block 9 slides up and down through the cooperation of the slider 10 and the slide groove, ensuring the stable movement of the threaded rod 12. The servo motor 11 drives the threaded rod 12 to rotate, causing the movable block 9 to move upward, thereby gradually releasing the life ring. The contact surface between the ball block 13 and the life ring is arc-shaped to reduce frictional resistance and ensure that the life ring slides out smoothly. The inner diameter of the protective cylinder 1 and the bottom shell 2 are strictly matched with the outer diameter of the life ring to prevent the life ring from shaking during transportation. Multiple life rings can be stacked in the protective cylinder 1 and released sequentially through the limiting mechanism 3 to achieve continuous throwing.

[0026] Working principle:

[0027] After the drone carrying the throwing device flies to the target area, the flight control system triggers the servo motor 11 to start. The servo motor 11 drives the threaded rod 12 to rotate. Since the threaded rod 12 is screwed to the internal threaded tube 14, the movable block 9 slides upward along the slide groove. When the movable block 9 moves upward, the lifebuoy loses the limiting obstruction of the ball block 13 and slides along the inclined surface of the bottom shell 2 towards the throwing port. When the extended ball block 13 contacts the inclined surface of the bottom shell 2, it can act as a limiting obstruction before the lifebuoy slides out, ensuring that the lifebuoy is released as needed. After one throwing is completed, the servo motor 11 reverses, driving the movable block 9 to reset, and the next lifebuoy automatically falls into the limiting position. Repeating the above process can achieve continuous throwing. The structural design of the protective cylinder 1 and the bottom shell 2 ensures that the lifebuoy remains stable during flight and throwing, avoiding throwing failure due to external interference. The entire device achieves precise and efficient rescue operations through mechanical linkage and motor control.
