The invention discloses a submersible type solid phase microextraction sampling device which comprises a submarine body, an extraction mechanism and a sealing plate, the submarine body is provided with a hollow mounting cavity, a water inlet is formed in the bottom of the mounting cavity, the extraction mechanism comprises a mounting frame, a pressing plate, a lifting assembly and a plurality of sets of extraction units, and the mounting frame comprises a mounting plate and a fixing plate; the pressing plate is arranged between the mounting plate and the fixing plate in a sliding mode, each extraction unit comprises a needle seat and a probe inserted into the needle seat, the needle seats are fixedly arranged on the fixing plate, the tops of the probes are fixedly connected with the pressing plate, the lifting assembly can drive the pressing plate to move in the vertical direction, and the sealing plate is arranged in the water inlet in a sliding mode. By means of the arrangement, the submarine body is used for conveying the multiple sets of extraction units to the preset depth, the transmission assembly is used for lowering the pressing plate to expose the bottoms of the probes, meanwhile, the water inlets are opened, the bottoms of the multiple probes can make contact with a to-be-sampled water sample at the preset depth at the same time, and multiple samples are collected at the same time.

    本发明公开了一种潜水式固相微萃取采样装置,包括潜水艇本体、萃取机构和密封板,潜水艇本体具有中空的安装腔,安装腔的底部开设有进水口,萃取机构包括安装架、压板、升降组件和多组萃取单元,安装架包括安装板和固定板,压板滑动设置于安装板和固定板之间,每组萃取单元包括针座和插装于针座的探针,针座固定设置于固定板上,探针的顶部与压板固定连接,升降组件且能够驱使压板沿竖向移动,密封板滑动设置于进水口内。通过上述设置,利用潜水艇本体将多组萃取单元运送至预定深度,并利用传动组件,在降低压板以露出探针底部的同时打开进水口,使多个探针的底部能够同时与预定深度的待采样水样接触,同时采集多份样品。
