The utility model provides an underground water sampling pump with a piston water storage structure, and relates to the technical field of sampling pumps. A driving motor is mounted in the shell; two limiting columns are symmetrically welded in the shell, a connecting pipe is slidably connected in the shell, and the connecting pipe is connected with the two limiting columns in a clamped mode. Through the arrangement of the water inlet, the water inlet and the water outlet are formed in the upper portion of the shell, and the water inlet is obliquely formed, in the using process, due to the fact that the water inlet is oblique, a check valve can be conveniently installed, and the problems that firstly, an existing device is not convenient enough when the check valve is installed, and the installation efficiency is affected are solved; and secondly, the problem that the extraction amount is easily reduced due to the fact that the extraction speed of an existing device is too high during extraction is solved. 本实
