Description

TECHNICAL FIELD

[0002] In water quality detection, the water quality of different water layers can be quite different. The traditional sampling method can only obtain water samples of a single depth, and it is difficult to comprehensively and accurately reflect the overall water quality of the water body. With the increasing requirements for water resource protection and management, it is necessary to more accurately understand the water quality parameters of different depths of the water body.

[0003] For example, Chinese patent CN219104458U discloses a water body layered sampling device. This device can solve the problem that the existing water body layered sampling device can only simply sample the water body to be detected, which is inconvenient for sampling samples of different depths, resulting in inaccurate sampling data and cannot truly reflect the situation of water bodies of different depths.

[0004] However, in the above-mentioned technical solution, when the liquid taking assembly of the layered sampling device for water quality detection continues to penetrate downward after sucking the water body, there will be residual water in the interior of the liquid taking assembly, which will pollute the water body during the next sampling, making the experimental results inaccurate. Therefore, we propose a layered sampling device for water quality detection, which can clean the interior of the sampling device after the previous work, ensuring that the next sampling can obtain pure samples and ensuring the accuracy and quality of water body detection.
