s3, driving the threaded rod to rotate by utilizing the motor, so that the threaded rod drives the sealing sleeve in threaded connection to move upwards, thereby exposing the water inlet, and at the moment, the threaded rod drives the adjusting plate in threaded connection to move upwards, so that the adjusting plate contacts with the bottom surface of the supporting plate, the supporting plate moves out of the placing groove, and the supporting plate and the pulled-open protective net can support the hole wall;
s4, groundwater enters the collecting pipe through the water inlet hole for collection;
s5, when the water in the collecting pipe increases, the floating ball is driven to rise, the floating ball drives the connected T-shaped rod to move upwards, and when the water quantity is enough, the T-shaped rod is contacted with the pressure sensor, so that the pressure sensor sends out a signal to prompt a worker by using external control equipment;
s6, the device supporting plate is retracted by the motor, the water inlet hole is sealed by the sealing sleeve, the device is pulled out by the cable, and then the sample can be taken out by the water outlet valve.
