The invention belongs to the technical field of liquid rockets, and particularly relates to a dynamic stabilizing device for propellant filling during marine launching of a liquid rocket, which comprises a storage part, a collection mechanism, a damping mechanism and an auxiliary mechanism, the storage part comprises a storage tank and a sealing plate; the sealing plate is detachably mounted at the upper end of the storage tank; the collecting mechanism comprises a buoyancy plate, a connecting cylinder and a sliding rod, the bottom of the connecting cylinder is fixedly connected with the upper end face of the buoyancy plate, and the sliding rod is slidably arranged in an inner cavity of the connecting cylinder; the damping mechanism comprises a mounting frame, two magnetic blocks and a transmission plate, the transmission plate is a metal conductor plate, the mounting frame is rotatably mounted on the bottom surface of the closing plate, the two magnetic blocks are fixedly mounted on the outer wall of the mounting frame, and the magnetic poles of the ends, close to each other, of the two magnetic blocks are opposite; the fluctuation energy is absorbed through the change of buoyancy, so that the liquid level shaking amplitude is reduced, the liquid level shaking frequency is prevented from being the same as the shaking frequency of the storage tank, and the effects of damping and improving stability are achieved.

    本发明属于液体火箭技术领域,具体的说是液体火箭海上发射加注推进剂的动态稳定装置,包括存储部、采集机构、阻尼机构和辅助机构;存储部包括存储罐和封闭板,封闭板可拆卸安装在存储罐的上端;采集机构包括浮力板、连接筒和滑杆,连接筒的底部与浮力板的上端面固定连接,滑杆滑动设置在连接筒的内腔;阻尼机构包括安装架、磁力块和传动板,传动板为金属导体板,安装架转动安装在封闭板的底面,磁力块固定安装在安装架的外壁,并设置有两个,两个磁力块相互靠近的一端磁极相反;通过浮力的变化吸收波动能量,进而减小液面晃动的幅度,防止液面晃动的频率与存储罐晃动的频率相同,从而达到减震提高稳定性的效果。
