The invention discloses multi-layer water taking equipment for water quality monitoring, and belongs to the field of water taking equipment.The multi-layer water taking equipment comprises a sampling pipe, a water guide pipe is fixedly connected to the outer surface of the sampling pipe, a water storage cavity is formed in the inner side of the water guide pipe, a water injection assembly is arranged on the inner side of the water guide pipe, and the water injection assembly comprises a movable part and a water injection part; the movable part comprises a limiting plate fixedly connected with the outer surface of the water guide pipe, the outer surface of the limiting plate is slidably connected with a floating rod, and the outer surface of the floating rod is fixedly connected with a connecting plate. Through the arrangement of the water injection assembly, when synchronous sampling operation is carried out on water at different depths, the sampling pipe is vertically placed into the water, and the sealing ring can seal the interior of the water guide pipe, so that the water at different depths can be prevented from entering the same group of water guide pipes, and the probability of doping among water at different depths can be reduced; and therefore, the stratified sampling precision can be effectively improved.
本发明公开了一种水质监测用多层次取水设备,属于取水设备领域,包括取样管,所述取样管外表面固定连接有导水管,所述导水管内侧开设有储水腔,所述导水管内侧设置有注水组件,所述注水组件包括活动部与注水部,所述活动部包括与导水管外表面固定连接的限位板,所述限位板外表面滑动连接浮动杆,所述浮动杆外表面固定连接有连接板。可以实现通过设置注水组件,在对不同深度的水进行同步取样操作时,将取样管呈竖直状放入水中,密封圈能够对导水管内部进行密封,从而能够阻止不同深度的水进入相同一组导水管内,从而能够降低不同水深水质之间出现掺杂的几率,进而能够有效地提高分层取样精度。
