The invention discloses a bulkhead sealing device for a floating propulsion system. The bulkhead sealing device comprises a split shell assembly, a ball sealing ring inner ring assembly, a ball sealing ring outer ring assembly, a gear transmission mechanism, a hydraulic motor and an electromagnetic directional valve. The split type shell assembly and the ball seal ring outer ring assembly are arranged on the ball seal ring inner ring assembly in a sleeving mode, the axial inner side of the ball seal ring outer ring assembly is used for making contact with a main shaft boss, and an end face sealing ring is arranged on the axial inner side of the ball seal ring outer ring assembly. The spherical seal ring outer ring assembly and the spherical seal ring inner ring assembly form a spherical hinge in clearance fit; the gear transmission mechanism comprises a lead screw and a plurality of gears; the hydraulic motor is connected with the gear transmission mechanism; wherein the hydraulic motor is used for driving the gear transmission mechanism, the gear transmission mechanism converts rotary motion into linear motion and drives the ball seal ring inner ring assembly and the ball seal ring outer ring assembly to move towards the axial inner side, and the spherical hinge is used for adjusting the angle of the ball seal ring outer ring assembly so that the axial inner side of the ball seal ring outer ring assembly can be attached to and sealed with a main shaft boss.

    本发明公开了一种浮式推进系统用隔舱密封装置,包括:剖分式壳体组件、球封环内环组件、球封环外环组件、齿轮传动机构、液动马达与电磁换向阀;剖分式壳体组件、球封环外环组件分别套设在球封环内环组件上,球封环外环组件的轴向内侧用于和主轴凸台接触,球封环外环组件的轴向内侧上设有端面密封圈;球封环外环组件与球封环内环组件构造出间隙配合的球面铰;齿轮传动机构包括丝杠和多个齿轮;液压马达与齿轮传动机构连接;其中,液压马达用于驱动齿轮传动机构,齿轮传动机构将旋转运动转换为直线运动,驱动球封环内环组件和球封环外环组件向轴向内侧运动,球面铰用于调整球封环外环组件的角度,使球封环外环组件的轴向内侧与主轴凸台贴合并密封。
