The invention discloses a smoke injection system for a police unmanned aerial vehicle. The smoke injection system comprises an unmanned aerial vehicle holder, a stepping motor is installed at the axis of the outer wall of the bottom of the unmanned aerial vehicle holder through bolts, a rim seat is welded to the outer wall of the bottom of the stepping motor through a bobbin, and a limiting groove is formed in the axis of the inner side wall of the rim seat; a gear ring is welded to the inner side wall of the limiting groove, rotating discs are arranged on the outer walls of the top and the bottom of the limiting groove, rectangular grooves distributed in an annular structure at equal intervals are formed in the periphery of the outer wall of the front face of each rotating disc, and roller columns are movably connected to the inner walls of the two ends of each rectangular groove through rotating shafts. Smoke can be sprayed at different angles around, the smoke spraying area is enlarged, the smoke spraying efficiency is improved, the structure is novel, operation is convenient, and the practicability is high; and the roller columns slide in the positioning rings, the smoothness of the box body in the rotating process is improved, the structure is compact, practicability is high, and the system is suitable for popularization.
本发明公开了一种警用无人机用的烟雾喷射系统,包括无人机云台,无人机云台底部外壁的轴心处通过螺栓安装有步进电机,且步进电机底部外壁上通过筒管焊接有轮圈座,轮圈座内侧壁轴心处开设有限位槽,且限位槽的内侧壁上焊接有齿圈,限位槽的顶部和底部外壁上设置有转盘,且转盘正面外壁的四周开设有等距离呈环形结构分布的矩形槽,矩形槽两端的内壁上通过转轴活动连接有辊柱。本发明可对四周不同角度进行烟雾喷射,扩大了烟雾喷射面积,提升了烟雾喷射的效率,结构新颖,操作方便,实用性强;辊柱在定位圈的内部滑动,提升了箱体转动过程中的流畅性,结构紧凑,实用性强,适合推广。
