Columnar Sediment Sampling System with In-Situ Data Acquisition Function

The present disclosure provides a columnar sediment sampling system with an in-situ data acquisition function, including a data acquisition unit and a columnar sampler. The data acquisition unit includes a hydrological data acquisition unit and a heat flow data acquisition unit. The hydrological data acquisition unit includes a multi-parameter hydrological recorder, a bracket and a connecting rod. The multi-parameter hydrological recorder is mounted in the bracket. The hydrological data acquisition unit is mounted above the columnar sampler through the connecting rod. The columnar sampler is provided with a ballast lead block and a sampling pipe. The present disclosure may achieve continuous acquisition of full -depth-water multi-parameter hydrological data with single lowering of the columnar sampler and fully utilise the ship time for lowering and withdrawing of the sampler.
