The invention relates to the technical field of unmanned aerial vehicles, and provides a fire extinguishing unmanned aerial vehicle which comprises an unmanned aerial vehicle body, two fixing strips are symmetrically and fixedly mounted at the bottom of the unmanned aerial vehicle body, convex sliding grooves are formed in the bottoms of the two fixing strips, and convex sliding blocks are movably embedded in the two convex sliding grooves. According to the invention, when a fire extinguishing bomb is gradually thrown to a forest fire site, the mass of the whole unmanned aerial vehicle body is reduced, and the pressure of the weight of the fire extinguishing bomb on a disc II is gradually reduced, so that the disc II gradually moves towards a disc I under the reset acting force of a compression spring II, and a movable rod I synchronously slides upwards along the disc I; the distance between the first disc and the second disc is gradually decreased, so that the size of the fire extinguishing bomb carrier is decreased, wind resistance borne by the fire extinguishing bomb carrier is small, the situation that the unmanned aerial vehicle body shakes can be avoided, and then the flying safety of the unmanned aerial vehicle body is improved.
本发明涉及无人机技术领域,提供了一种消防灭火无人机,包括:无人机本体,所述无人机本体的底部对称固定安装有两个固定条,两个所述固定条的底部均开设有凸形滑槽,两个所述凸形滑槽的内部均活动嵌设有凸形滑块。本发明,当灭火弹逐渐投放到森林火灾场地时,无人机本体整体的质量变轻,此时圆盘二受到的灭火弹重量的压力逐渐变小,使得圆盘二在压缩弹簧二的复位作用力下,逐渐朝向圆盘一移动,同步使活动杆一沿圆盘一向上滑动,从而使圆盘一与圆盘二之间的距离逐渐变小,从而使灭火弹载体的体积变小,这样灭火弹载体受到的风阻较小,从而可以避免无人机本体出现晃动的情况,进而提高无人机本体飞行的安全性。
