The invention relates to a repeatable unfolding device capable of being used for protection, and belongs to the technical field of spacecraft protection. Comprising an extensible protective cover, an unfolding mechanism, a mounting seat, a rope driving mechanism and a locking mechanism, the mounting seat is of a conical cylinder structure which is vertically arranged in the axial direction; the interior of the mounting base is a hollow cavity, and a circular opening is formed in the top of the mounting base; the unfolding mechanism is arranged at the outer edge of the top opening of the mounting seat; the deployable protective cover is connected with the extending end of the deploying mechanism; the rope driving mechanism and the locking mechanism are both mounted on the deployable protective cover; the unfolding mechanism rotates by taking the outer edge of the opening in the top of the mounting seat as an axis to drive the deployable protective cover, the rope driving mechanism and the locking mechanism to turn over; the rope driving mechanism drives the deployable protection cover to unfold or fold; the locking mechanism is used for locking the deployable protective cover in an unfolding state; the protection device can be flexibly folded and locked after being unfolded, and therefore protection on equipment in a specific area of a spacecraft is achieved.

    本发明涉及一种可用于防护的可重复展开装置,属于航天器防护技术领域;包括可展开保护罩、展开机构、安装座、绳索驱动机构和锁紧机构;安装座为轴向竖直放置的锥柱体结构;安装座的内部为中空腔体,且安装座的顶部设置有圆形开口;展开机构设置在安装座顶部开口的外沿处;可展开保护罩与展开机构的伸出端连接;绳索驱动机构和锁紧机构均安装在可展开保护罩上;展开机构实现以安装座顶部开口的外沿为轴旋转,带动可展开保护罩、绳索驱动机构和锁紧机构翻转;绳索驱动机构实现驱动可展开保护罩展开或折叠;锁紧机构实现对可展开保护罩展开状态下的锁定;本发明能够实现防护装置的柔性折叠以及展开后的锁定,从而实现对航天器特定区域设备的保护。
