【摘要】：為解決采樣海水從吊放式采水器到儲(chǔ)存分配系統(tǒng)對(duì)接傳輸問(wèn)題,根據(jù)海水取樣要求,提出了一套海水從采水器到分配儲(chǔ)存系統(tǒng)的對(duì)接傳輸裝置設(shè)計(jì)方案.對(duì)接傳輸裝置由上定對(duì)接頭和下對(duì)接座組成,其中上定對(duì)接頭的導(dǎo)向爪組與下對(duì)接座的錐鋼套采用桿錐方式的粗對(duì)接,以補(bǔ)償上定對(duì)接頭滑套中心底錐孔與下對(duì)接座導(dǎo)向錐管的二次精對(duì)接定位誤差,降低其定位精度要求.這樣,從機(jī)械結(jié)構(gòu)上保證了采水器到分配儲(chǔ)存系統(tǒng)的海水偏心流道的O形密封圈裝配要求.為了消除對(duì)接過(guò)程中各種變差對(duì)系統(tǒng)的影響,該裝置采用了彈簧阻尼減震,再配以波紋管柔性連接補(bǔ)償軸向位移及徑向偏心,目的是為延長(zhǎng)裝置壽命.基于Solid Works Motion仿真還原了整個(gè)對(duì)接系統(tǒng)定心過(guò)程,揭示了裝置中各種變差對(duì)系統(tǒng)的影響.再基于Solid Works Simulation仿真了導(dǎo)向爪組在對(duì)接過(guò)程中的受力狀態(tài),驗(yàn)證了整個(gè)裝置結(jié)構(gòu)設(shè)計(jì)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.
