The invention discloses a fire extinguishing unmanned aerial vehicle capable of automatically avoiding obstacles, and belongs to the field of unmanned aerial vehicles, the fire extinguishing unmanned aerial vehicle comprises upper and lower main body plates, the two main body plates are connected through four connecting short pipes, extension sheets are arranged on the front and rear sides of the main body plates, and positioning columns are rotatably arranged in the middles of the extension sheets; a torsion arm is fixedly installed on the positioning column, an impeller is arranged at the top end of the torsion arm, and the impeller is installed at the output end of the servo motor. When the unmanned aerial vehicle device is used, a worker enables the unmanned aerial vehicle device to take off and enter a fire-fighting site through a remote controller, when a narrow slit exists in the fire-fighting site, a stepping motor drives two spiral blocks to start to rotate, spiral grooves in the outer sides of the spiral blocks fluctuate while the spiral blocks rotate, and a positioning needle twists; at the moment, the torsion arms can be twisted along with the positioning needle and combined together, the width of the unmanned aerial vehicle equipment is narrowed, and then the unmanned aerial vehicle equipment can fly in a small gap.

    本发明公开了一种自动避障的灭火无人机,属于无人机领域,该装置包括主体板,所述主体板共设置有上下两个,两个主体板之间通过四个连接短管连接,所述主体板的前后两侧均设置有延伸片,延伸片的中间旋转设置有定位柱,定位柱上固定安装有扭转臂,所述扭转臂顶端设置有叶轮,叶轮安装在伺服电机的输出端上。本发明在使用的时候,工作人员通过遥控器让无人机装置起飞进入到救火现场,当救火现场有窄缝的时候,步进电机带动两个螺旋块开始旋转,螺旋块在旋转的同时,螺旋块外侧的螺旋槽会波动定位针发生扭转,此时的扭转臂会随着定位针一起扭转并且合并在一起,无人机设备的宽度就变窄了,进而无人机设备就可以在较小的缝隙里飞行。
