[0002] UAVs, short for unmanned aerial vehicles, are aircraft capable of autonomous flight or remote control without human control. They are primarily operated using radio remote controls and self-contained programmable controls. They boast advantages such as small size, low cost, ease of use, minimal operational requirements, and strong battlefield survivability.

[0003] Drones can be classified according to their purpose and size. Based on their purpose, drones can be divided into two categories: military and civilian. Military drones are typically used for tasks such as reconnaissance, communications relay, and electronic jamming, while civilian drones are widely used in agricultural monitoring, environmental monitoring, aerial photography, and other fields. Based on their technical configuration, drones can be divided into fixed-wing, helicopter (including coaxial twin-propeller, tandem, and traditional configurations), multi-rotor, compound wing, and tilt-rotor types. In addition, based on their empty weight and take-off weight, drones can be divided into different levels such as micro, light, small, medium, and large.

[0004] With the development of science and technology, in the field of UAV technology, especially the need for rapid response to water rescue applications, UAVs have the advantages of quick response and strong maneuverability, and are being used more and more widely. Therefore, the requirements for water rescue technology itself are also getting higher and higher. Therefore, finding a method of using UAVs to carry aerial lifesavers is a new requirement and idea.

[0005] The existing method of deploying lifebuoys is mostly manual deployment, and there are many water rescue areas that are inaccessible to humans, so timely rescue cannot be carried out; some use drones to deploy lifebuoys for rescue, but some drone lifebuoy deployment equipment has limited limit on the lifebuoy when transporting the lifebuoy, which can easily cause the lifebuoy to shake left and right during transportation, which will affect the flight stability of the drone.

[0006] Therefore, it is necessary to design an aerial lifebuoy delivery device based on a drone to solve the above-mentioned problems. Utility Model Content

[0011] As a preferred solution of the present invention, the clamping heads located on the left and right sides drive the hydraulic rods through hydraulic cylinders to fix the lifebuoy.

[0012] As a preferred solution of the present invention, the bottom of the hydraulic rod is fixedly connected to an electric telescopic rod, and a resistance rod is fixedly connected to one side of the lifebuoy below the electric telescopic rod.

[0013] As a preferred solution of the present invention, the front ends of the interference rods on the left and right sides are spherical in design to clamp and fix the position below the lifebuoy.

[0025] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0026] The aerial lifebuoy delivery device based on a drone includes a drone body 1, and side frames 2 are fixedly connected to the left and right sides of the drone body 1. A blade 3 is installed on the upper side of the side frame 2 away from the drone body 1. The lower part of the blade 3 is driven by a brushless motor. A protective cover 4 is also provided on the periphery of the blade 3. A lifebuoy fixing structure 5 is provided at the bottom of the side frame 2 through a connecting frame 7. A lifebuoy 6 is fixed on the lifebuoy fixing structure 5. A camera 10 is installed in the middle position of the lower front side of the drone body 1. A 4G module is also provided inside the drone body 1. The remote control end of the drone is wirelessly connected to the drone body 1 through the 4G module.

[0027] Specifically, the lifebuoy fixing structure 5 includes a hydraulic cylinder 51 fixedly connected to the connecting frame 7, the output end of the hydraulic cylinder 51 is connected to a hydraulic rod 52, and the side of the hydraulic rod 52 away from the hydraulic cylinder 51 is fixedly connected to a clamping head 53; the clamping heads 53 on the left and right sides drive the hydraulic rod 52 through the hydraulic cylinder 51 to fix the lifebuoy 6; the hydraulic cylinder 51 is remotely controlled by the remote control end of the drone to work, and then the hydraulic cylinder 51 controls the hydraulic rod 52 to retract, thereby releasing the originally fixed lifebuoy 6 to achieve the purpose of aerial delivery.

[0028] Among them, the bottom of the hydraulic rod 52 is fixedly connected to an electric telescopic rod 54, and the bottom of the electric telescopic rod 54 is fixedly connected to a resistance rod 55 on one side of the lifebuoy 6; the bottom of the hydraulic rod 52 is fixedly connected to the electric telescopic rod 54, and the bottom of the electric telescopic rod 54 is fixedly connected to a resistance rod 55 on one side of the lifebuoy 6; in the process of contraction of the above-mentioned hydraulic rod 52, the resistance rod 55 is synchronously moved away from the lifebuoy 6; further, the upper and lower positions of the resistance rod 55 can be changed by the electric telescopic rod 54 to adapt to lifebuoys 6 of different sizes.

[0029] Preferably, a buffer rod 8 is fixedly connected to the bottom of the left and right connecting frames 7, and a supporting seat 9 is fixedly connected to the bottom of the buffer rod 8; when the drone body 1 lands on the ground after transporting the lifebuoy 6, the buffer rod 8 and the supporting seat 9 are used for buffering to reduce the direct impact of the ground on the drone body 1 during landing.

[0030] The working process of the present invention is as follows: when using the drone-based aerial lifebuoy delivery device, the hydraulic cylinder 51 is first controlled by the remote control end of the drone body 1 to operate, so that the hydraulic rod 52 contracts and releases, and then the lifebuoy 6 is placed between the two clamping heads 53, and then the hydraulic cylinder 51 is controlled to operate again, so that the hydraulic rod 52 extends to make the lifebuoy 6 be put on the left and right clamping heads 53. At the same time, the resistance rod 55 resists the left and right sides of the bottom of the lifebuoy 6, and then, the remote control of the drone body 1 is used to control the drone body 1 to fly to the sky above the designated delivery position. After reaching the sky, 4G technology is used to remotely control the drone remote control to control the hydraulic cylinder 51 again to operate, so as to cause the hydraulic rods 52 on the left and right sides to contract, thereby releasing the originally fixed lifebuoy 6, thereby achieving the purpose of aerial delivery.
