Description

technical field [0001] The invention relates to the technical field of environmental monitoring, and more specifically relates to a device and method for collecting and storing water samples for environmental monitoring. Background technique [0002] At present, when carrying out environmental monitoring, it is necessary to sample and test water samples at different water depths. The common method is to lower the liquid inlet of the sampling pipe to a designated water depth, and then take a water sample at that position, and place the water sample after it is taken. to other storage facilities for storage. This sampling method is inconvenient to operate, and the collected water samples need to be stored in other equipment, which increases equipment investment and reduces work efficiency. Contents of the invention [0003] The invention overcomes the disadvantages of inconvenient operation and low work efficiency in collecting and storing environmental monitoring water sam...
