s4, according to the real-time data sent back by the liquid level sensor (81), an operator can check the height of the water level at a computer end and perform online monitoring on the reserve volume of underground water resources;
s5, an operator pulls the pull rope (74) upwards, the pull rope (74) drives the liquid blocking plate (73) to rotate, underground water resources enter an inner cavity of the sampling cup (4) from the position of the liquid outlet (72), after 10-15S, the operator releases the pull rope (74), under the rebound action of the torsion spring (75), the liquid blocking plate (73) is clamped on the surface of the liquid outlet (72) again to seal the liquid outlet (72), then the operator starts the electric hoist (3), and the electric hoist (3) lifts the water sample protection box (1) out of the monitoring hole through the rope (82);
s6, water sample protection box (1) takes out the back, operating personnel stirs driving lever (65) downwards, driving lever (65) drive spacing fastener (62) overcome the elasticity downstream of spring (64), make the top of spacing fastener (62) break away from spacing draw-in groove (63), make to sample cup (4) break away from spacingly, operating personnel will sample cup (4) and take out from water sample protection box (1) inner chamber, will sample the groundwater sample in cup (4) inner chamber and take out, for the censorship.
