An air fire-extinguishing bomb dropping device and method of an unmanned aerialvehicle

Abstract

The invention discloses an air fire-extinguishing bomb dropping device of an unmanned aerial vehicle, whihch includes a hanging plate for carrying the whole throwing device and connecting an unmannedaerial vehicle body ;a connecting lug connected to the mounting plate; a hanging frame, which is connected with a connecting lug, wherein the two hanging frames are arranged opposite to each other toform a space for placing a ball-shaped dry powder fire-extinguishing bomb; a locking link, one end of the locking link being connected to the hanging frame and the other end of the locking link beingconnected to the control mechanism; a control mechanism connected to the mounting plate, the control mechanism comprising a swing linkage, a series linkage support and a series linkage connected to the series linkage support; the servo steering gear whichis connected with the control mechanism, and the servo steering gear controls the swinging linkage and the series linkage of the control mechanism to make the horizontal motion, so as to realize the opening or closing state of the control mechanism. The invention also discloses an air fire-extinguishing bomb dropping method of an unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial fire extinguishing bomb throwing device and method of an unmanned aerial vehicle. Background technique [0002] Forest fire emergency has been paid more and more attention by the country. When a fire occurs or a potential hidden fire source is found, most firefighters throw fire extinguishing bombs by hand. This type of fire extinguishing bomb is thrown, and its accuracy is poor, and the personal safety of firefighters is not guaranteed. With the development of UAV technology, UAV supporting special load equipment is widely used in the field of forest firefighting. Firefighters can use UAV to mount fire extinguishing bombs to throw from the air. [0003] At present, the technology of domestic UAV fire extinguishing bomb throwing equipment is immature, and it is still unable to meet the following requirements: 1. The spherical dry powder fire extinguish...

AI Technical Summary

Problems solved by technology

[0003] At present, the technology of domestic UAV fire extinguishing bomb throwing equipment is immature, and it is still unable to meet the following requirements: 1. The spherical dry powder fire extinguishing bombs are accurately thrown to the fire source; 2. Individual throwing in batches; 3. 1. Automatic throwing in the air; 4. Precise throwing; 5. Light weight, can be mounted with the help of a small multi-rotor drone; 6. Has sufficient strength and rigidity, and there will be no problems such as vibration when mounted on the drone. Does not affect aircraft safety
