According to the sampler for the unmanned aerial vehicle, a cup opening of a sampling cup can be always kept upward under the action of gravity through a rotating shaft and a rotating groove, water sample scattering caused when the unmanned aerial vehicle flies is avoided, meanwhile, stable flight of the unmanned aerial vehicle is guaranteed through a multi-stage buffer structure, and the sampling efficiency is improved. The sampling structure is characterized in that a take-off and landing rod is of a symmetrical structure, a fixed circular ring is fixedly arranged in the middle of the take-off and landing rod, an outer circular ring is arranged in the fixed circular ring through a rotating shaft, a connecting circular ring is arranged in the outer circular ring through a rotating shaft, and an inner circular ring is arranged in the connecting circular ring through a rotating shaft; a sampling cup is arranged on the inner circular ring, the inner circular ring is arranged at the middle upper part of the sampling cup, the two ends of the lifting rod horizontally extend in the direction far away from the fixed circular ring, then are gradually bent downwards, then are bent in the direction far away from the fixed circular ring and then vertically extend upwards, and the lowest end of the lifting rod is lower than the lowest end of the sampling cup. And the damping device is arranged on the sampling device.

    本发明一种无人机用采样器公开了一种能够通过转动轴和转动槽使取样杯在重力的作用下一直保持杯口向上,避免无人机飞行时造成水样洒落,同时通过多级缓冲结构,保证无人机的平稳飞行,减缓无人机飞行中杯内水体的晃动幅度的采样结构,其特征在于起降杆为对称结构,起降杆中部固定置有固定圆环,固定圆环内通过转动轴置有外圆环,外圆环内通过转动轴置有连接圆环,连接圆环内通过转动轴置有内圆环,内圆环上置有取样杯,且所述内圆环置于取样杯的中上部位,起降杆的两端均向远离固定圆环的方向水平延伸,再逐渐向下折弯,再向远离固定圆环的方向折弯,再向上竖直延伸,所述起降杆最低端低于取样杯最低端,减震装置置于采样装置上。
