Abstract

The application relates to the technical field of sampling devices, and discloses an underground water sampling device which comprises a lifting frame, a hollow shaft, a spline housing, a spline shaft, a cylinder, a helical blade, a rotating shaft, a circular plate and a filter cartridge. When the rotary type rotary drum is used, the hollow shaft is driven by external force to rotate, and then the cylinder, the helical blades and the circular plate can be driven to synchronously rotate. Then, the lifting frame is controlled to work, and the 匚 template can synchronously descend the cylinder, the spiral blade and the circular plate until the cylinder, the spiral blade and the circular plate are inserted into the ground sampling position. And the spline shaft can drive the rotating shaft to move after being driven by external force to slide, so as to drive the circular plate to move, and the circular plate can open the lower port of the cylinder. At this time, the underground water can enter the cylinder after being filtered by the filter cylinder. Finally, the belleville pipe is placed into the cylinder through the through hole, so that the underground water in the cylinder can be collected, and the underground water sampling work is completed. The drilling device is not required to be additionally arranged for hole turning, and the operation is simple and convenient.
