The invention provides a follow-up unfolding type plume dust raising prevention closed opening and closing device and method, and belongs to the technical field of spaceflight. The problems that an existing opening and closing mechanism is complex in mechanism and large in occupied space in the release application occasion of the volatile component preparation unit are solved. The cover opening and closing device comprises an opening and closing mechanism and a locking mechanism, the opening and closing mechanism is installed on the upper end face of a cover opening and closing rack, and the locking mechanism is arranged perpendicular to the upper end face of the cover opening and closing rack; when a bulge on an unlocking assembly mounting seat is matched with a right-angle surface of one groove, a locking pressing block at the upper end of an unlocking rotating shaft presses a pressing part of a sample receiving opening and closing cover, an opening and closing mechanism is in a closed state, and a free-ranging film cover and an absorbing sheet film cover of the opening and closing mechanism cover an opening in the upper end surface of an opening and closing cover rack; when the unlocking deflector rod is rotated, the unlocking deflector rod drives the unlocking rotating shaft to rotate and simultaneously lifts upwards, so that the locking pressing block unlocks the sample receiving opening and closing cover, and the sample receiving opening and closing cover is in an open state under the action of the elastic piece. The method is suitable for preventing the influence of plume dust raising on the volatile component preparation process.
本发明提供了一种随动展开式防羽流扬尘密闭开合装置及方法,属于航天技术领域。解决现有开合机构在挥发分制备单元的释放应用场合存在机构复杂占用空间大的问题。它包括开合机构和锁紧机构,开合机构安装在开合盖机架的上端面上,锁紧机构垂直开合盖机架的上端面布置;当解锁组件安装座上的凸起与其中一个凹槽的直角面配合时,解锁转轴上端的锁定压块压紧接样开合盖的压紧部,开合机构处于关闭状态,开合机构的散养薄膜盖和吸纳片薄膜盖覆盖开合盖机架的上端面上的开口;转动解锁拨杆,解锁拨杆带动解锁转轴转动的同时向上抬起使锁定压块解锁接样开合盖,接样开合盖在弹性件作用下处于开启状态。本发明适用于防止羽流扬尘对挥发分制备过程的影响。
