The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for sampling detection of underground pipelines, which comprises an unmanned aerial vehicle body, a stop lever mechanism convenient for supporting the unmanned aerial vehicle body during sampling is arranged on the unmanned aerial vehicle body, and a sampling mechanism convenient for the unmanned aerial vehicle body to sample is arranged on the unmanned aerial vehicle body. The stop lever mechanism comprises a push rod, a movable ring, a fixed shaft and a telescopic rod, a cabin is formed in the side end of the unmanned aerial vehicle body, and two cylindrical grooves are formed in the lower end of the inner side wall of the cabin in a penetrating mode. Through cooperation of a connecting plate and a first spring, when sludge stored in the sampling box moves downwards, a certain pulling force is increased, the situation that when the unmanned aerial vehicle body ascends, the sampling box is stressed to move downwards too fast, and the stability of the unmanned aerial vehicle body is affected is avoided, it can be guaranteed that the sampling box is in a slow downward moving state, and the sampling efficiency is improved. And a certain protection effect is achieved when the unmanned aerial vehicle body ascends.
本发明涉及无人机技术领域,特别是涉及一种用于地下管道采样检测的无人机,包括无人机机体,所述无人机机体上设有便于在采样时对无人机机体进行支撑的挡杆机构,所述无人机机体上设有便于无人机机体进行采样的取样机构,所述挡杆机构包括推杆、活动环、固定轴和伸缩杆,所述无人机机体的侧端部开设有机舱,所述机舱内侧壁的下端部贯穿开设有两个柱形槽。本发明通过设置了连接板和第一弹簧相配合,在采样箱内存储上污泥向下移动时,提高一定的拉力,避免在无人机机体上升时,采样箱受力向下移动过快,对无人机机体机身的稳定性造成影响,可以保证采样箱处于较缓向下移动的状态,在无人机机体升起时起到一定的防护作用。
