The invention discloses a planetary seismograph autonomous slow release device which comprises a lander and a planetary seismograph, the lander is electrically connected with the planetary seismograph below the lander, the planetary seismograph autonomous slow release device further comprises a mounting disc, explosive bolts and a damping pay-off mechanism, and the mounting disc is mounted at the bottom of the lander; the planetary seismograph is mounted at the bottom of the mounting disc through explosive bolts; the damping pay-off mechanism is installed on the installation disc, and the damping pay-off mechanism is connected with the planetary seismograph through a rope. According to the invention, on one hand, load tension of a launching section and a planet landing section can be borne, reliable installation and fixation of the planet seismograph and a lander are ensured, on the other hand, the planet seismograph can be autonomously released to the planet surface, a speed limiting function and a swing slowing function are provided in the falling process, and impact at the landing moment of the planet seismograph is reduced; and bouncing and even rollover after landing are avoided.
本发明公开了一种行星地震仪自主缓慢释放装置,包括着陆器和行星地震仪,着陆器与其下方的行星地震仪电性连接,还包括安装盘、爆炸螺栓和阻尼放线机构,安装盘安装在着陆器的底部;行星地震仪通过爆炸螺栓安装在安装盘的底部;阻尼放线机构安装在安装盘上,且阻尼放线机构与行星地震仪通过线绳连接。本发明一方面,能够承受发射段和行星着陆段的载荷拉力,保证行星地震仪与着陆器可靠安装固定,另一方面,能够自主释放行星地震仪到行星表面,并在下落过程中提供限速功能和减缓摆动功能,降低行星地震仪落地瞬间的冲击,避免落地后弹起乃至侧翻。
