Description

technical field [0001] The invention relates to the technical field of layered collection of deep lake water samples, in particular to a device for layered collection and storage of deep lake water samples. Background technique [0002] Water quality status is one of the important evaluation indicators to measure the quality of the ecological environment. Water quality monitoring and analysis are the main means to detect the components in the water body. Water sample collection is a key link in water quality monitoring. In order to ensure the accuracy of water quality analysis, First of all, it is necessary to ensure the standardization of water sample collection and storage. When collecting deep lake water samples, due to the long depth of the lake in the vertical direction, there are large differences in water body density and pressure between layers, and different layers have different ecological properties. In order to study the ecological environment at different levels...

Problems solved by technology

[0003] In addition, when collecting water samples from deep lakes, the collection device is usually moved downward directly, and the collection device can easily drain the upper water body downward. When collecting water samples in layers, the collected water samples are cross-mixed water samples , the accuracy is greatly reduced, which cannot meet the needs of follow-up research, especially in the study of deep lake water samples, the differences in water bodies at different levels are relatively large, the longitudinal water flow is easy to damage the stratification performance, and the turbulent flow in the water body is easy to It will affect the moving direction and cause the direction to shift, which is not conducive to the recovery of the collection device. Different positions at the same height will also affect the composition of the water sample and affect the analysis effect
