Description

Technical Field

[0001] The utility model belongs to the technical field of water rescue, and in particular relates to a water rescue device based on unmanned aerial vehicle traction. Background Art

[0002] For water rescue, drones can now be used to pull up the rescue airbag and drag it to the water surface. Currently, the connection between the two is basically through a sling. However, due to the space limitations of drones, it is not conducive to the layout of the rope winding device. Therefore, the sling is always in a taut state, that is, there is a large height difference between the rescue airbag and the drone. Due to the influence of its own gravity and the influence of wind during driving, the rescue airbag will cause insufficient stability, which is not conducive to the control of the drone.

[0003] At the same time, the existing rescue airbags are of various types, not just limited to lifebuoys, such as cylindrical airbags, wearable airbag clothing or boat-shaped airbag boats and other airbag structures with various functions. The current rescue is to use lifebuoys mounted on drones, and the remaining airbag parts will have a worse stability problem due to the larger contact surface with the gas.

[0004] Therefore, it is a problem that needs to be solved by the staff in this field to design a rescue device that can connect the rescue airbag to the drone and release it instantly after it is in place. Utility Model Content
