Columnar and Box-Type Integrated Sampler Applicable to Deep-Sea Sediment Sampling Operation

The present disclosure provides a columnar and box-type integrated sampler applicable to deep-sea sediment sampling operations, including a scraper knife connecting rod system, a box-type sampling system, a columnar sampling system and an in-situ hydrological parameter collection system. The scraper knife connecting rod system includes a lifting fence connected to a driving mechanism and a release lock catch fixed on a bracket, and is connected with a scraper knife at the bottom end of the sampler through a connecting rod. The box-type sampling system is provided with a ballast lead block; the top is provided with a sealed box cover; the bottom is provided with a sampling box body; a fixed plate is arranged on the outer side; and the columnar sampling system is connected to the fixed plate; a main body of the columnar sampling system is a sampling pipe; the top of the sampling pipe is provided with a unidirectional valve, and the bottom is provided with a knife head; a liner pipe is sleeved inside; and the in-situ hydrological parameter collection system is located above the ballast lead block. The present invention achieves single lowering of the columnar sampler and the box-type sampler and in-situ collection of hydrological information, and fully uses the ship time of lowering and withdrawing of the samplers.
