The invention discloses an ecological environment water quality detection sampling device and a sampling method thereof. The sampling device comprises a first gas conveying pipeline, a second gas conveying pipeline, and a gravity ball, a first airbag and a sampling cylinder which are arranged at the lower end of the second gas conveying pipeline; the first air bag is communicated with the lower end of the second air conveying pipeline; the first air bag is subjected to inflation and deflation control through the second air conveying pipeline; the gravity ball is fixedly arranged in the first air bag; the sampling cylinder is connected to the lower end of the gravity ball; the two second air bags at the lower end of the first air conveying pipeline are positioned in the sampling cylinder; when the second air bag contracts, a gap is formed between the second air bag and the inner wall of the sampling cylinder; when the second air bag is inflated, the second air bag is in close contact with the inner wall of the sampling cylinder. The first air bag is inflated through the second air conveying pipeline, and the buoyancy of the first air bag is adjusted according to the inflation degree, so that the whole sampling device ascends or descends at a constant speed, and the stability of the device is improved.

    本发明公开了一种生态环境水质检测采样装置及其采样方法。采样装置包括第一输气管道、第二输气管道以及设置在所述第二输气管道下端的重力球、第一气囊和采样筒;所述第一气囊连通在所述第二输气管道的下端;通过所述第二输气管道对所述第一气囊进行充放气控制;所述重力球固定设置在所述第一气囊的内部;所述采样筒连接在所述重力球的下端;所述第一输气管道下端的两个第二气囊位于所述采样筒内;当所述第二气囊收缩时,与所述采样筒内壁产生间隙;当所述第二气囊充气时,与所述采样筒内壁紧密接触。通过第二输气管道向第一气囊内充气,根据充气的大小,调节第一气囊的浮力大小,从而使采样装置整体匀速上升或下降,提高装置稳定性。
