Same-diameter multi-time water pumping device for hydrogeological drilling

The same-diameter multi-time water pumping device comprises a bottom plate, a rectangular groove is formed in the lower end of the bottom plate, a U-shaped plate is installed in the middle of the upper end of the bottom plate, a water pump is installed on the right portion of the upper end of the bottom plate, and the left inner wall and the right inner wall of the U-shaped plate are jointly and movably connected with a vertical plate. A motor is installed at the upper end of the vertical plate, a rectangular through groove is formed in the front end of the vertical plate, and the output end of the motor extends into the rectangular through groove and is connected with a lead screw. According to the same-diameter multi-time water pumping device for hydrogeological drilling, the pressure sensor, the spring, the guide rod and the sieve plate are arranged to be matched together so that the water taking pipe can be prevented from making contact with rocks, it is avoided that the water taking pipe continues to des
