Abstract:

Based on the operation principle analysis of hydrostatic corer, a novel sediment corer driven by marine hydrostatic was proposed, which was supported by the research of operational mode trigger mechanism of hydrostatic corer controlled by sampling tube's support reaction force, and the research of hydrostatic pressure driven sampling mechanism based on distribution flow spool position's control in driven units. Mechanical structure of the corer was designed firstly. Then, the prototype was completed. Finally, a practical sea trial was conducted successfully. The results of the sea trial verify the reasonableness of the hydrostatic corer's design.
