The negative pressure of the sampling tube 54 draws the water inside the river into the sampling tube 54 through the sampling port 55 at one end. Then, by placing the sampling tube 54 in water bodies of different depths, sample collection work at different positions can be completed, thereby achieving the effect of sampling different water depths without using multiple sampling devices, which is convenient for personnel to use;
