Description

Technical Field

[0001] The utility model relates to the technical field of water body stratified sampling, in particular to a water body stratified sampling device. Background Art

[0002] Collect water samples from polluted water bodies and obtain basic data on water pollution through analysis and measurement. Water samples for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, and frequency are determined according to the characteristics of the water body and the purpose of analysis. Water samples for analyzing the chemical composition of natural water in rivers are generally collected 0.2 to 0.5 meters below the water surface in the flow measurement section of the hydrological station. Sampling points should be increased when the section is open. Shore sampling points must be located where the water flow is unobstructed. If necessary, sampling can also be carried out in layers at different depths. The number of sampling times is evenly distributed in different periods and different flow rates according to changes in water conditions.

Therefore, we need to provide a water layered sampling device. Utility Model Content
