Description

TECHNICAL FIELD

[0001] The present application relates to the field of unmanned aerial vehicles and applications, and in particular to a fire-fighting bomb throwing device. BACKGROUND

[0002] With the rapid development of unmanned aerial vehicle technology and the maturation of the market, unmanned aerial vehicles are widely used in the fields of firefighting, transportation, and investigation. In the field of firefighting, unmanned aerial vehicles often throw fire-fighting bombs through a throwing device to extinguish fires.

[0003] The existing throwing device needs to be pre-processed when using fire-fighting bombs, that is, the safety pin of the fire-fighting bomb needs to be manually pulled out or the limiting tail of the safety pin needs to be manually cut off. The fire-fighting bomb that has undergone such pre-processing is in an unstable state and is prone to explosion and cause danger to personnel in the case of misoperation.

[0004] For example, Chinese patent CN211663452U provides a fire-fighting bomb throwing device for unmanned aerial vehicles, which includes a throwing cylinder, a release assembly (a rudder-driven pull rod controls a release buckle), a guide groove, and other structures. The device realizes accurate throwing of fire-fighting bombs through the driving of a rudder. Similar to the present application, the device uses a rudder-driven mechanical structure to realize the throwing action, but does not involve the automatic pulling out and secondary disassembly of the safety pin of the fire-fighting bomb.

[0005] In addition, most throwing devices cannot safely disassemble the fire-fighting bomb that has been pulled out without performing the throwing task. Even if the fire-fighting bomb with the tail of the safety pin cut off can be disassembled, it cannot be restored to its original state and can only be scrapped, causing waste.
