The invention relates to the technical field of small celestial body detection, in particular to a sample anti-escape device in a microgravity environment, which comprises a mechanical arm tail end execution assembly, a lofting container and a flexible door, and is characterized in that the mechanical arm tail end execution assembly is driven by a multi-degree-of-freedom mechanical arm to collect sample particles on the celestial body surface in the peripheral area of the lofting container; the sample particles are conveyed into a sample placing container; the flexible door is arranged at the opening end of the lofting container and is integrally formed with the lofting container; the sample containing container is used for containing sample particles with the diameter larger than or equal to 30 mm. As an important component of a small celestial body sample sealing subsystem, the small celestial body sample storage device is mainly responsible for storage and escape prevention work of samples collected by a mechanical arm, storage of celestial body sample particles with the diameter larger than or equal to 30 mm can be achieved, a flexible door is installed and fixed in a limited space, and opening and closing of the flexible door are achieved under the passive condition; sample particles in the lofting container are prevented from escaping.
本申请涉及小天体探测技术领域,具体而言,涉及一种微重力环境下样品防逃逸装置,包括机械臂末端执行组件、放样容器以及柔性门,其中:机械臂末端执行组件在多自由度机械臂的驱动下采集放样容器周边区域天体表面的样品颗粒,并将样品颗粒运送至放样容器中;柔性门设置在放样容器的开口端,与放样容器一体成型;放样容器用于收纳放置直径≥30mm的样品颗粒。本申请作为小天体样品密封子系统的重要组成部分,主要负责机械臂采集样品的收纳和防逃逸工作,能够实现对直径≥30mm天体样品颗粒的收纳,在有限的空间下进行柔性门的安装固定,在无源条件下实现柔性门的开启与闭合,防止放样容器内部的样品颗粒逃逸。
