Meanwhile, the water sampling volume of the bottle-type water sampler is limited, water samples with different water depths are possibly mixed in the sampling process, the controllable distance is short, and the labor consumption in the sampling process is large. The vacuum pump is limited by air pressure for pumping water and sampling, and when the water depth exceeds 10 meters, the water sample cannot be normally pumped and collected because the vacuum pump reaches the atmospheric pressure.
