【摘要】：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Solid Works 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Solid Works 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.
[Abstract]:In order to solve the problem of the docking transfer of the sampled seawater from the suspended water collector to the storage and distribution system, according to the requirement of seawater sampling, A design scheme of a docking transmission device for seawater from water collector to distribution storage system is put forward. The docking transmission device consists of upper pair joint and lower butt joint. The guide claw group of the upper pair joint and the tapered steel sleeve of the lower butt seat adopt the coarse docking method of the rod cone to compensate the secondary fine docking error between the bottom cone hole in the upper fixed pair joint slide sleeve and the guide cone tube in the lower butt seat. In order to eliminate the influence of various variations on the system during the docking process, the O-ring assembly requirements of the water collector to the seawater eccentric flow channel of the distribution storage system are ensured from the mechanical structure. The device adopts spring damping to reduce vibration, coupled with corrugated tube flexible connection to compensate axial displacement and radial eccentricity. In order to prolong the device's life, the whole centering process of docking system is simulated and restored based on Solid Works Motion. The influence of various variations in the device on the system is revealed, and the force state of the guide claw group in the docking process is simulated based on Solid Works Simulation, which verifies the rationality of the structure design of the whole device.
