为解决采样海水从吊放式采水器到储存分配系统对接传输问题, 根据海水取样要求, 提出了一套海水从采水器到分配储存系统的对接传输装置设计方案. 对接传输装置由上定对接头和下对接座组成, 其中上定对接头的导向爪组与下对接座的锥钢套采用杆锥方式的粗对接,以补偿上定对接头滑套中心底锥孔与下对接座导向锥管的二次精对接定位误差, 降低其定位精度要求. 这样, 从机械结构上保证了采水器到分配储存系统的海水偏心流道的O形密封圈装配要求. 为了消除对接过程中各种变差对系统的影响, 该装置采用了弹簧阻尼减震, 再配以波纹管柔性连接补偿轴向位移及径向偏心, 目的是为延长装置寿命. 基于SolidWorks Motion仿真还原了整个对接系统定心过程, 揭示了装置中各种变差对系统的影响. 再基于SolidWorks Simulation仿真了导向爪组在对接过程中的受力状态, 验证了整个装置结构设计的合理性.

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.
