The invention discloses an unmanned aerial vehicle high-altitude gas sampler. The sampler comprises an unmanned aerial vehicle body and a sampling module, the sampling module is mounted at the bottom of the unmanned aerial vehicle body and comprises a sampling block, a plurality of cavities formed in the sampling block, a telescopic piece and a piston plate; the telescopic piece comprises a fixed end and a telescopic end, the fixed end is connected with the sampling block, and the telescopic end is connected with the piston plate; the upper part of the cavity is communicated with the external space of the sampling block, and the lower part of the cavity is provided with a valve module; the piston plate is in interference fit with the cavity and can move in the axial direction of the cavity; and the valve module is opened when the telescopic end of the telescopic piece moves, and is closed when the telescopic end of the telescopic piece stops moving. The valve module is opened when the telescopic end of the telescopic piece moves and is closed when the telescopic end of the telescopic piece stops moving, and air leakage in the sampling block can be effectively prevented.

    本发明公开了一种无人机高空气体取样器,所述取样器包括:无人机体以及取样模块;所述取样模块,安装在所述无人机体的底部,包括取样块、若干个设于所述取样块内的空腔、伸缩件以及活塞板;所述伸缩件,包括固定端和伸缩端,所述固定端与所述取样块连接,所述伸缩端与所述活塞板连接;所述空腔,其上方与所述取样块的外部空间连通,其下方设有阀门模块;所述活塞板,与所述空腔过盈配合,可沿所述空腔的轴向移动;所述阀门模块,在所述伸缩件的伸缩端移动时开启,在所述伸缩件的伸缩端停止移动时关闭。本发明阀门模块在伸缩件的伸缩端移动时开启,在伸缩件的伸缩端停止移动时关闭,可有效防止取样块内的空气泄漏。
