s3: when the sensor senses to the bottom, the sensor stops to be placed, clean water is injected into the water pump (1) in a reverse direction, then the water pump (1) is started, the water pump (1) can pump water at the upper end of the air pushing ring (415) outwards, the air pushing ring (415) can be enabled to move upwards at the moment, the air at the lower end of the air pushing ring (415) has an upward pushing force, the upper water stopping ball (5231) is driven to move upwards under the action of the pumping force of the air at the moment, a gap is reserved between the connecting rod (5232) and the sampling piece (521), water flows into the sampling bin from the gap, when the pumping force of the air continues to act, the lower water stopping ball (5233) plugs the opening of the sampling piece (521) at the moment, the water stopping effect is achieved, the water pump (1) is stopped at the moment, the upper water stopping ball (5231) rapidly drops under the reaction force, the opening of the sampling piece (521) is plugged again, a part of the sampling bin can remain liquid at the moment, and the sampling bin is further sampled.
7. The method of claim 6, wherein in S3, after the weight (432) enters the water body, the gravity of the sealing weight (433) is greater than the buoyancy of the water, the lower end opening of the liquid storage bin (4321) is in a closed state, after the weight (432) is sunk to the bottom, the sealing weight (433) is supported, the weight (432) continues to move downwards, a gap is reserved between the weight (432) and the sealing weight (433), and the water can enter the liquid storage bin (4321) to sample the water bottom.
