The invention provides a thermal control device for a space telescopic rod mechanism and a satellite-borne laser radar. The thermal control device comprises a sleeve, a push rod, a supporting frame and a heat insulation assembly. One end of the push rod extends into the telescopic sleeve and is in sliding fit with the telescopic sleeve, one end of the supporting frame is connected with the end, extending out of the telescopic sleeve, of the push rod, the push rod drives the supporting frame cover to synchronously move in the length direction of the telescopic sleeve, and the supporting frame cover is arranged on the push rod. The heat insulation assembly wraps the supporting frame. The supporting frame and the push rod are kept in a relatively static state all the time through the supporting frame moving along with the push rod and the heat insulation assembly, thermal protection is conducted on the push rod through the heat insulation assembly wrapping the supporting frame, the push rod is not directly affected by external heat flow all the time, thermal deformation of the push rod is reduced, and thermal protection on the push rod is achieved.
本发明提供了一种用于空间伸缩杆机构的热控装置及星载激光雷达,包括套筒、推杆、支撑框架以及隔热组件;所述推杆的一端伸入伸缩套筒内并与其滑动配合,所述支撑框架的一端与推杆伸出伸缩套筒的一端连接,所述推杆带动支撑框架罩沿伸缩套筒长度方向同步运动,且所述支撑框架罩设推杆;所述隔热组件包覆支撑框架。通过与推杆随动的支撑框架和隔热组件,使支撑框架与推杆始终保持相对静止的状态,借助包覆在支撑框架上的隔热组件对推杆进行热防护,使推杆始终不受外热流的直接影响,有助于减少推杆的热变形,实现对推杆的热保护。
