Abstract

The invention relates to a deep sea sampling technology, and aims to provide a deep sea multi-path high-spatial-resolution water sampler carried on an ROV (Remote Operated Vehicle). The water sampler comprises a flow distribution valve structure, a conversion valve structure and a piston structure, the flow distribution valve structure comprises a flow distribution valve and a driving motor; the conversion valve structure comprises a conversion valve and a driving motor; the piston structure comprises a piston drawing structure and a driving motor. A piston drawing structure is used for providing a negative pressure condition for the water sampler, and under the condition of maintaining the original state of the deep sea water environment, high-spatial-resolution collection is performed on a deep sea water sample in real time, so that water body samples at different positions, different depths and different time resolutions are obtained. The invention provides important technical means support for the development of a deep sea water sampling technology in the fields of marine natural gas hydrate exploration and exploitation, marine ecological environment monitoring and the like. The device can be carried on equipment such as a deep-sea mobile platform and an ROV (Remote Operated Vehicle) to sample sea water of 4000 meters and above deep sea.
