本发明提供了一种四点联动释放的非自锁螺纹式连接分离装置及方法,属于航天领域。解决了传统的卫星分离方案已经无法满足当前和未来微纳卫星的分离需求的问题。它包括卫星、运载平台、连接锁紧组件和解锁触发组件,解锁触发组件安装在运载平台的中心处,连接锁紧组件设置四组,且四组连接锁紧组件均匀布置在解锁触发组件的四周,四组连接锁紧组件各通过一条约束纤维线与解锁触发组件连接,卫星通过四个连接螺杆与四组连接锁紧组件的正反丝套筒连接,锁紧状态下,四组连接锁紧组件将卫星锁紧在运载平台上,分离时,解锁触发组件运作使四组连接锁紧组件同步解锁,释放卫星。本发明结构紧凑,所占空间小,冲击低,无污染,解锁同步性好。

    The invention provides a four-point linkage release non-self-locking thread type connection and separation device and method, and belongs to the field of spaceflight. The problem that a traditional satellite separation scheme cannot meet the separation requirements of current and future micro-nano satellites is solved. The device comprises a satellite, a carrying platform, four connecting locking assemblies and an unlocking triggering assembly, the unlocking triggering assembly is installed at the center of the carrying platform, the four connecting locking assemblies are evenly arranged on the periphery of the unlocking triggering assembly, and the four connecting locking assemblies are connected with the unlocking triggering assembly through constraint fiber lines respectively. The satellite is connected with the forward and reverse thread sleeves of the four connecting and locking assemblies through the four connecting screws, in the locking state, the satellite is locked on the carrying platform through the four connecting and locking assemblies, and during separation, the unlocking trigger assembly operates to enable the four connecting and locking assemblies to be unlocked synchronously, and the satellite is released. The device is compact in structure, small in occupied space, low in impact, free of pollution and good in unlocking synchronism.
