To solve the docking problem of seawater sampling from lifting multi-bottle ampling arrays to storage and distribution, a set of design schemes for seawater transfer ocking device according to seawater sampling requirements is proposed. The docking ransmission device is composed of an upper fixed joint and a lower docking seat, where compressed guide claws surrounding the upper joint contact the lower cone, making a ough claws-cone docking mechanism and compensating rod and cone docking of the second ine docking of the positioning error to lessen the positioning accuracy requirements. The echanical structure ensures to meet the requirements of O-ring assembly in the seawater eccentric flow channel from the samplers to the distribution system. To eliminate the influence f variations in the docking process, the axial displacement and radial eccentricity are ompensated by the flexible connection of the orrugated pipe. The purpose is to prolong he service life of the device. Based on the SolidWorks Motion simulation, the centering rocess of the whole docking system is simulated to reveal influence of various kinds of ariations on the docking mechanism. The stress state of the guide claw in the docking rocess is simulated with SolidWorks Simulation, showing rationality of the structure design.
