The invention relates to the technical field of drag reduction of moon pool engineering ships, in particular to a moon pool bottom sealing device and method. Comprising a baffle assembly which is arranged at the bottom of the moon pool, is used for closing and opening the moon pool and comprises a plurality of baffles which are connected in series, and every two adjacent baffles are hinged to each other; the driving assembly comprises a plurality of first driving oil cylinders; the locking assembly is arranged opposite to the driving assembly and fixed to the other side wall, opposite to the driving assembly, of the moon pool, and when the baffle assembly seals the moon pool, the locking assembly locks and limits the baffle assembly; the moon pool bottom sealing device is simple in structural form, small in occupied moon pool space and low in cost, the first driving oil cylinder drives the baffle assembly to seal the moon pool, the resistance of a moon pool ship during sailing is reduced, and the cost is saved; the baffle assembly is vertically folded and stored on one side of the moon pool, the operability is good, and the extremely high popularization and practical value is achieved.

    本发明涉及月池工程船减阻技术领域,尤其涉及一种月池底部封闭装置及方法;包括:挡板组件,设置于月池的底部,用于封闭、开启所述月池,包括多个串联连接的挡板,相邻两个所述挡板之间铰接;驱动组件,包括多个第一驱动油缸;锁紧组件,与所述驱动组件相对设置,固定在与所述驱动组件相对的所述月池的另一侧壁上,所述挡板组件封闭所述月池时,所述锁紧组件对所述挡板组件进行锁紧限位;月池底部封闭装置,结构形式简单,占用月池空间小,成本低,通过第一驱动油缸带动挡板组件对月池进行封闭,减小月池船航行时的阻力,节省成本;挡板组件竖直折叠收纳在月池的一侧,可操作性好,具有极高的推广和实用价值。
