Layered automatic sampling device of automatic water quality monitoring station

The utility model discloses a layered automatic sampling device of an automatic water quality monitoring station, which comprises a sampling frame and a filter screen, and a plurality of groups of adjusting cavities are uniformly arranged on the inner surface of the sampling frame. After the water taking pipeline and the water taking pump are adopted and water depth detection is carried out, the water taking pipeline can be released to have different lengths through different running time of a plurality of groups of driving motors, and at the moment, water can be extracted through a sampling head in a supporting seat at the bottom of the water taking pipeline; the sampling water quality is directly guided to an analysis instrument from the output pipe through the operation of the water taking pump, so that the sampling water quality at different depths does not need to be lifted and then detected, and the phenomenon that the sampling water quality is damaged and mixed is avoided; the device can be supported o
