The invention discloses a propeller locking device and method of an engine, and relates to the technical field of aircrafts. The sleeve is fixedly connected to the side, away from the engine, of the first mounting base, and a notch is formed in the side wall of the sleeve; the first mounting seat is provided with a first mounting hole communicated with the sleeve; a groove is formed in the inner wall of the first mounting hole, and the supporting piece is connected into the groove in a sliding mode and partially extends into the first mounting hole; one end of the limiting piece extends into the sleeve and abuts against the top face of the supporting piece, and a bolt hole is formed in the other end of the limiting piece. One end of the limiting bolt penetrates through the mounting hole of the propeller and is connected to the bolt hole; the clamping mechanism is detachably connected to the end face of the output shaft of the engine and penetrates through the notch to clamp the limiting piece. The side, away from the groove, of the supporting piece is connected to the clamping mechanism. According to the unmanned aerial vehicle, unintentional swinging of the propeller in the transportation process is effectively prevented, so that the risk that the propeller collides with the inner wall of the box body is reduced, and the overall safety and reliability of the unmanned aerial vehicle are ensured.
本申请公开了一种发动机的锁桨装置及方法,涉及飞行器技术领域。套管固定连接于第一安装座远离发动机的一侧,套管的侧壁设置有缺口;第一安装座设置有与套管贯通的第一安装孔;第一安装孔的内壁设置有凹槽,支撑件滑动连接于凹槽内,并部分伸入第一安装孔;限位件的一端伸入套管内并抵接于支撑件的顶面,另一端设置有螺栓孔;限位螺栓的一端穿过螺旋桨的安装孔并连接于螺栓孔;夹紧机构可拆卸连接于发动机输出轴端面,并穿过缺口夹紧限位件;支撑件远离凹槽的一侧连接于夹紧机构。本申请有效地防止了螺旋桨在运输过程中的无意摆动,从而降低了螺旋桨与箱体内壁发生碰撞的风险,确保了无人机的整体安全性和可靠性。
