Water taking device with quantitative function for surface water quality detection

The invention relates to the technical field of surface water taking, and discloses a water taking device with a quantitative function for surface water quality detection, the water taking device comprises a water pumping unit, the water pumping unit comprises a small water pump and a water inlet pipe arranged at the water inlet end of the water pump, and scale values are arranged on the outer pipe wall of the water inlet pipe; the water outlet pipe is arranged at the water outlet end of the water suction pump. According to the water taking device with the quantitative function for surface water quality detection, water with the required depth is quantitatively sampled by selecting the depth of the water inlet pipe inserted into water, the extracted water sample is divided into initial water and rear water, and the initial water is used for cleaning the inner wall of the water pipeline and discarding the water, so that the accuracy of water sample detection is improved, and the detection efficiency is improve
