The sampler widely used at present is a sampler with an upper cover and a lower cover, wherein the bottom of the sampler is provided with a water inlet cover, and the top of the sampler is provided with a drainage cover. When the sampler is put into water, the sampler sinks by means of dead weight, the liquid pushes open the water inlet cover at the bottom, so that a water sample automatically and continuously flows into the sampler along with the continuous transfer of the sampler, when the sampler is completely immersed into the water, the water discharge cover is opened, the sampler continuously sinks, and the liquid continuously flows into the sampler from the water inlet at the bottom and flows out from the water outlet at the top. When the sampler stops moving, the upper cover and the lower cover fall back to the original positions by means of self weight, and the water inlet and the water outlet are closed, so that sampling is completed. Although the water sample is supposed to continuously flow in and continuously flow out from the sampler, the sinking speed of the sampler cannot be matched with the inflow and outflow of the water sample due to the internal resistance of the sampler, so that the sample is a mixed sample with different depths, fixed-point sampling cannot be achieved, the sampled sample is not representative, and the error is large when the concentration of the water sample changes greatly along with the depth of the water.
