Description

Technical Field

[0001] The utility model relates to the field of throwing devices, in particular to an aerial throwing device for an aircraft. Background Art

[0002] With the continuous maturity and development of civil drone technology, the application of drones in water rescue has received more and more attention. Drones have the advantages of low maintenance cost, flexible take-off and landing, and simple operation. At present, drones have been used in many aspects of water rescue, such as personnel positioning and search and rescue, long-distance video transmission, positioning and medical rescue equipment, and undertake monitoring, exploration, and search. For example, after receiving a report of people falling into the water at sea, the drone can take off from the nearest rescue boat and find and locate the specific location of the person in distress from the air at the first time. As a modern aerial flight platform, drones will experience shaking of the equipment carried during flight, and cannot achieve good results in accurate throwing during shaking, causing life jackets or lifebuoys to fall too far away from the person in distress, resulting in rescue failure.

[0003] According to a UAV stable throwing device provided by patent publication number CN216301478U, the UAV stable throwing device includes a UAV tripod and a stabilizing component; the stabilizing component is a parallel arranged strip component connected to the UAV tripod. The UAV is equipped with a thrower, and the stabilizing component is located below the thrower hook of the thrower. The device has a simple structure, is easy to implement, can be fixed and disassembled, and is convenient to obtain materials. The device is lightweight and has little effect on the load of the UAV, and is suitable for most throwing situations. The device mainly affects the degree of swing of the thrown heavy object during the flight of the UAV, thereby improving the throwing accuracy. In rescue operations, the use of the device can prevent objects from shaking in the air and accurately deliver them to the vicinity of the person in distress, achieving stable control of life jackets or lifebuoys, and greatly improving the quality of rescue.

[0004] There are still some shortcomings in the patent application. The patent can limit the shaking of the thrown objects to a certain extent, but life jackets or lifebuoys are light items. When encountering strong winds, the thin rope will be driven by the suspended objects to deviate from the predetermined landing point, and accurate throwing cannot be achieved. Therefore, an aerial throwing device for an aircraft is needed to solve this problem. Utility Model Content
