before monitoring, the turntable (14) is rotated to drive the transmission mechanism to transmit, so that the screw (8) synchronously rotates to drive the stop block (9) to slide to one end of the screw (8) far away from the water taking part (51), and the stop block is exposed from the outlet and extrudes the inner wall of the drilled hole;
when water exists in the drill hole and the water-swelling water stop strip (12) is soaked, the water-swelling water stop strip (12) swells to fill the gap position between the stop block (9) and the drill hole;
water enters the cavities (511) of the water taking part (51) from the water seepage port (512), the sensor (19) obtains water quality condition information of the water and converts the information into an electric signal, the electric signal is transmitted to the background through the microcontroller, and a monitoring result is displayed on the background.
