The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-falling protection device for a police unmanned aerial vehicle. A through hole is formed in the upper end of the unmanned aerial vehicle shell, a through pipe is mounted on the through hole, and an air pump is mounted at the lower end of the through pipe; a buffering mechanism is installed at the upper end of the unmanned aerial vehicle shell and comprises a first outer cylinder fixedly installed at the upper end of the unmanned aerial vehicle shell, and the first outer cylinder communicates with the through pipe; a connecting mechanism is arranged on the periphery of the buffering mechanism, the connecting mechanism comprises a connecting cylinder communicating with the first outer cylinder body, and an air outlet pipe is arranged at the upper end of the connecting cylinder; the first arc-shaped barrel and the second arc-shaped barrel are jointly combined to form a semi-annular structure which is annularly arranged on the periphery of the propeller and used for protecting the propeller so as to reduce hair twining on the propeller, and the air outlet pressure of the air outlet holes is increased by increasing the pressure of the air pump so as to improve the defense effect of the gas defense wall on the periphery of the propeller.

    本发明涉及无人机技术领域,具体为一种警用无人机的防坠落保护装置,包括无人机外壳;所述无人机外壳的上端开设有通孔,所述通孔上安装有通管,所述通管的下端安装有气泵;所述无人机外壳的上端安装有缓冲机构,所述缓冲机构包括固定安装在所述无人机外壳上端的第一外筒体,所述第一外筒体与所述通管相连通;所述缓冲机构的四周设置有连接机构,所述连接机构包括与所述第一外筒体相互连通的连接筒,所述连接筒的上端开设有出气管;第一弧形筒和第二弧形筒共同组合成的半环形结构环设在螺旋桨的外周,用于对螺旋桨进行防护,以减少毛发缠绕在螺旋桨上,通过增加气泵的压力来增加出气孔出气的压力,以增加螺旋桨外周气体防御墙的防御效果。
