Abstract
A DGT passive sampling device for water body detection includes a bottom fixed unit, where the bottom fixed unit includes an inserting drill bit; a passive sampling unit arranged at the top of the bottom fixed unit; and a floating marking unit arranged at the top of the passive sampling unit, where the floating marking unit includes a winding cylinder I, and the winding cylinder I is movably connected to the chassis by control inner ropes. After the inserting drill bit is inserted into the underwater soils, the bottom cavity winding source is started, the rotation of the bottom cavity roll releases the downward movement of the middle ropes, so that the passive sampling unit falls, while the bottom cavity roll may make the passive sampling unit regularly distributed at different heights of the water bottom by releasing different lengths of the middle ropes.
