An ultra-deep reservoir stratified water sample and sediment core integrated artificial intelligence sampling device, comprising a sampling device main chamber, an attitude balance sensor, a propeller, a balance base, and a sampler body, wherein the attitude balance sensor and the sampler body are disposed inside the sampling device main chamber; the propeller is disposed outside the sampling device main chamber; and the balance base is located at a bottom end of the sampling device main chamber. The sampling device of the present invention is an intelligent sampling device integrating high-definition underwater topography observation, undisturbed sediment core collection, vertical stratified accurate sampling of water bodies, and real-time in-situ monitoring of key physical and chemical parameters, and can be flexibly applied to deep and shallow water environments under complicated conditions.

Intelligent device for integrated sampling of layered water and sediment core of deep reservoir

An experimental system comprises a water level indicator, a data processing module, and an experimental simulator. The water level indicator is connected to the data processing module, and the water level indicator is mounted nearby the experimental simulator when in use. The experimental simulator comprises several experimental units. Each experimental unit comprises a first pipe, a second pipe, and a third pipe, wherein the first pipe perpendicularly communicates with the second pipe, a check valve which allows water to flow out but allows no water to flow in is connected to the water outlet of the second pipe, and the third pipe perpendicularly communicates with the second pipe and is parallel to the first pipe. The heights of the third pipes of the several experimental units are in a decreasing or increasing order.
