Phytoplankton sampling device with water filtering function

The phytoplankton sampling device with the water filtering function comprises an L-shaped supporting rod, the left end of the L-shaped supporting rod is fixedly connected with a vertical pipe, the bottom end of the vertical pipe is of a plugging structure, and the top end of the vertical pipe is rotationally connected with a rotating box with an opening in the top. Through the arrangement of the telescopic handle assembly, the position and the operation length of a handle can be conveniently adjusted according to actual requirements, through the arrangement of the eight L-shaped clamping blocks and the phytoplankton collecting and water filtering assembly, the box-shaped filter screen can be rigidly connected and supported, and therefore a worker can directly control the box-shaped filter screen to obliquely scoop up algae and phytoplankton on the water surface conveniently; the sampling efficiency of the algae phytoplankton on the water surface is improved by utilizing an inclined scooping mode, by arranging
