[0001] This utility model relates to the technical field of water quality testing and sampling equipment, and in particular to a lake survey stratification water sampling device. Background Technology

[0002] A lake survey stratification sampling device is a device used to extract water from specific strata in lakes and water bodies. It is mainly used in fields such as environmental monitoring, water quality analysis, and ecological research. This type of device can extract water samples from specific water layers for water quality testing, ecological surveys, and water health assessments.

[0003] Existing lake survey stratification sampling devices involve fixing multiple sampling bottles to a mounting frame with bolts, connecting the bottle caps to a control unit using steel cables, placing the mounting frame in the lake to be surveyed, and opening different bottle caps according to different water depths via the control unit to collect water samples at a specific depth. After sampling, tools are needed to remove the sampling bottles and collect water samples from inside. This process is cumbersome and time-consuming, making it difficult to quickly install and remove the sampling bottles. Therefore, this solution proposes a new stratification sampling device for lake surveys to address these issues. Utility Model Content
