[0029] In order to ensure that the sampling device can be submerged in water, a counterweight portion may be provided as required. The counterweight portion may be provided on the upper portion of the upper plate 102 or around the cylindrical sampling tube 100 .

[0030] When sampling surface water, the columnar sampling tube 100 is slowly placed into the water body by connecting the hanging ring 103.
