A negative pressure type unmanned sampling ship disclosed by the present invention comprises a floating plate, a top plate and a sampling assembly, the floating plate and the top plate are connected through a telescopic rod, the sampling assembly comprises a plurality of fixing cylinders connected to the bottom end of the top plate, the fixing cylinders are uniformly arranged in a rectangular array form, the fixing cylinders are communicated with the top plate, and a pair of directional grooves is formed in the inner wall of each fixing cylinder. A sample storage barrel is slidably clamped in the fixed barrel, an exhaust valve is arranged on the sample storage barrel, a pair of directional blocks is arranged on the outer wall of the sample storage barrel, a plurality of holding grooves are formed in the two directional blocks, the directional blocks are slidably clamped in the directional grooves, and an opening and closing assembly is arranged at one end of the sample storage barrel; the sampling assembly can collect a water sample and a gas sample of a water-gas interface, and helps a user to detect the gas condition of the water-gas interface at the central position of a water body, so that the problem of insufficient research in the central area of the water body due to the fact that an existing sampling ship cannot collect the gas sample is solved; the greenhouse gas emission of rivers and lakes cannot be accurately evaluated.
本发明公开了一种负压式无人采样船,包括漂浮板、顶板和采样组件,漂浮板和顶板间通过伸缩杆连接,采样组件包括顶板底端接设的多个固定筒,固定筒以矩形阵列形式均匀排列,固定筒和顶板连通,固定筒内壁上开设有一对定向槽,固定筒内滑动卡设有储样筒,储样筒上设置有排气阀,储样筒外壁上设置有一对定向块,两个定向块上均开设有多个握持槽,定向块滑动卡设在定向槽内,储样筒一端设置有开合组件,本发明中设置的采样组件可对水样和水气界面的气体样本进行采集,帮助使用者检测水体中心位置水气界面的气体状况,从而解决了现有采样船无法采集气样导致的水体中心地区的研究不足,不利于准确评估河流和湖泊温室气体排放的问题。
