Hydrogeological water sampling probe

This utility model relates to the field of hydrogeological and environmental technology, and discloses a hydrogeological and environmental geological water sampling probe, comprising: a shovel body, a threaded cylinder fixedly connected to the top of the shovel body, a vertical cylinder threadedly connected to the inner wall of the threaded cylinder, a flexible tube inside the vertical cylinder, a housing connected to the top of the flexible tube, and a first quick-connect fitting installed at the bottom of the flexible tube. This hydrogeological and environmental geological water sampling probe, through the coordinated operation of its components, closes the control switch on top of the housing, the battery inside the housing powers the pump body, and the pump body begins operation, creating negative pressure inside the flexible tube, short tube, and convex cylinder. Water can then be drawn out through the filter holes, convex cylinder, short tube, and flexible tube. Because the suction end is far from the sedimented soil layer in the water during water sampling, it is not easy to draw up the sedimented soil particles, thereby significantly reducing the content of soil and other impurities in the water sample and reducing the probability of impurities clogging the filter holes, facilitating high-quality and effective water sampling.
