The invention discloses a harmful gas sampling device based on an unmanned aerial vehicle in the technical field of air sampling, and the harmful gas sampling device comprises an unmanned aerial vehicle body, a fixed box is arranged on the bottom side of the unmanned aerial vehicle body, and a lifting mechanism is arranged on the upper side of an inner cavity of the fixed box and comprises an electric telescopic rod and two groups of telescopic cylinders; the electric telescopic rod and the two telescopic cylinders are arranged on the upper side of an inner cavity of the fixing box, the two telescopic cylinders are symmetrically arranged on the two sides of the electric telescopic rod, two fixing bases are arranged at the bottom end of the fixing box, a sampling mechanism is arranged between the two fixing bases, and a first extrusion mechanism and a second extrusion mechanism are symmetrically arranged at the upper ends and the lower ends of the two fixing bases correspondingly. And a traction mechanism is arranged between the first extrusion mechanism and the second extrusion mechanism. The unmanned aerial vehicle can be used for sampling harmful gas, meanwhile, the sampling device is sealed immediately after sampling is finished, air circulation between the sampling device and the outside is prevented, and air sampling leakproofness and detection accuracy are guaranteed.

    本发明公开了空气采样技术领域的一种基于无人机的有害气体采样装置,包括无人机本体,无人机本体底侧设置有固定箱,固定箱内腔上侧设置有升降机构,升降机构包括电动伸缩杆和两组伸缩筒,电动伸缩杆以及两组伸缩筒均设置在固定箱内腔上侧,且两组伸缩筒对称设置在电动伸缩杆的两侧,固定箱底端设置有两组固定座,两组固定座之间设置有采样机构,两组固定座上下端分别对称设置有第一挤压机构和第二挤压机构,第一挤压机构和第二挤压机构之间设置有牵引机构。本发明能够使用无人机对有害气体进行采样,同时在采样结束之后立马将采样装置密封,防止了采样装置和外界的空气流通,保证了空气采样的严密性和检测准确性。
