The present invention relates to a foldable firefighting drone with a fire extinguisher, which comprises: a mainframe unit including an upper end base and a lower end base, which are connected to each other by a support pillar, and a wing supporter on a lower side of the upper end base; a wing unit in which an upper arm and a lower arm connected by a wing supporter and a wing unit pin are connected to a motor supporter by the wing unit pin, and in which a driving motor including a propeller is installed on one side of the motor supporter; and a cargo unit in which the fire extinguisher is mounted on a fire extinguisher transport box, and in which a quick coupler is fastened with a discharge unit of the fire extinguisher, and in which the quick coupler is connected to a hose, and in which the hose is connected to a solenoid and a nozzle. The present invention is able to extinguish fire on a high-rise building in an early stage, and protect the human lives and properties. In addition, in ordinary times, when the wing unit and the leg are folded, the volume of the drone can be much smaller than that of conventional drones. In addition, the position of the nozzle is maintained to have the same angle to the ground surface by the weight of the fire extinguisher, and when a fire-extinguishing agent is sprayed, the center of the generated repulsion force equals the center of the lifting force of the drone at any time. Accordingly, even if the spray repulsion force makes the drone move backward or a control command makes the drone move forward, the same spray angle is maintained, so the fire-extinguishing agent can be continuously sprayed to the point of fire, thereby efficiently extinguishing the fire.

    본 발명에 따른 소화기가 탑재된 접이식 화재진화 드론은 상단베이스와 하단베이스는 지지기둥으로 연결되고, 상단베이스의 하부에는 날개지지대가 설치된 메인프레임부;, 날개지지대와 날개부핀으로 연결된 상부암 및 하부암이 모터지지대와 날개부핀으로 연결되고, 모터지지대의 일측에는 프로펠러를 포함한 구동모터가 설치되는 날개부; 및 소화기가 소화기운반함에 탑재되고, 소화기의 토출부에는 퀵커플러가 체결되며, 퀵커플러는 호스와 연결되고 호스는 솔레노이드 및 노즐에 연결되는 화물부;를 포함하되, 고층건물의 화재발생시에 날개부와 다리를 펼치고 화재발생지점까지 비행하여 소화약재를 분사함으로써, 고층건물의 화재를 조기에 진압하여 인명과 재산을 보호하는 효과가 있다. 또한, 평상시에 날개부와 다리를 접으면, 종래의 드론에 비하여 부피가 매우 작아지는 효과가 있다. 또한, 노즐의 위치는 소화기의 중량에 의하여 지면과의 각도를 동일하게 유지되고, 소화약재 분사시 발생하는 반력의 중심은 항상 드론의 양력중심과 일치하므로, 분사반력에 의하여 드론의 위치가 후퇴하거나 제어명령에 의하여 전진하더라도 동일한 분사각도를 유지하므로 소화약재를 화재지점에 계속하여 분사할 수 있어서, 효율적으로 화재진화하는 효과가 있다.
