Description

Unmanned aerial vehicle four-shot fire extinguishing bomb throwing device Technical Field The utility model relates to the technical field of unmanned aerial vehicle matched equipment, in particular to an unmanned aerial vehicle four-fire extinguishing bomb throwing device. Background Unmanned aerial vehicle fire extinguishing bomb throwing device among the prior art, a can only be used for throwing spherical fire extinguishing bomb, adopts to hold a plurality of spherical fire extinguishing bomb of chamber dress, and unmanned aerial vehicle reaches the back of target position, opens the hatch door that holds the chamber, and spherical fire extinguishing bomb freely falls. The other type of fire extinguishing bomb is used for throwing a cylindrical fire extinguishing bomb, the fire extinguishing bomb is clamped and fixed by the clamp, and after the unmanned aerial vehicle reaches a target position, the clamp is controlled to be opened to throw the fire extinguishing bomb. In the first scheme, the number of fire extinguishing bombs put in cannot be precisely controlled, and meanwhile, spherical fire extinguishing bombs are usually designed to be directly thrown for use and lack safety devices such as safety bolts and the like equipped with bottled fire extinguishing bombs. In case of storage, transportation or non-emergency, the spherical extinguishing bomb may be triggered in advance due to false touch, high temperature or other unexpected factors, resulting in potential safety hazard. In the second scheme, the structure of the clamp is complex, the clamp needs to be controlled to be opened, the transmission structure is complex, and the cost is high. Meanwhile, the cylindrical fire extinguishing bomb thrown by the unmanned aerial vehicle is also not provided with a safety bolt, and potential safety hazards exist. Disclosure of utility model In view of the above analysis, the embodiment of the utility model aims to provide a four-fire extinguishing bomb throwing device of an unmanned aerial vehicle, which is used for solving the problem that the existing unmanned aerial vehicle fire extinguishing bomb throwing device can not realize throwing and simultaneously pulls out a safety latch.
