The invention relates to the technical field of ships, in particular to a moon pool structure of a polar scientific investigation ship, which comprises a moon pool, the moon pool is fixedly connected with a plurality of reinforcing pieces, the moon pool is provided with a first shell, the first shell is provided with a filter screen and a heating piece, the first shell is fixedly connected with and communicated with a second shell, and the second shell is provided with a filter screen and a heating piece. A filter screen is arranged on the first shell and used for filtering seawater entering the second shell, the second shell is fixedly connected and communicated with a guide pipe, a sliding push rod is arranged on the guide pipe in a sealing and sliding mode, the guide pipe and the sliding push rod are each provided with a round hole provided with a one-way valve, and the second shell is fixedly connected with a first power piece. Seawater in the moon pool is driven to rotate slowly through work of the first power part, surface shear flow caused by rotation can destroy a boundary layer formed under a still water condition and delay formation of a stable low-temperature interface required by ice crystal nucleation, and stability and safety of lowering test equipment are ensured by matching with collection of crushed ice by a filter screen in the first shell.
本发明涉及船舶技术领域,尤其涉及一种极地科考船的月池结构,包括有月池,所述月池固接有多个加强件,所述月池设置有第一壳体,所述第一壳体设置有滤网和加热件,所述第一壳体固接并连通有第二壳体,所述第一壳体上滤网用于对进入所述第二壳体内的海水进行过滤,所述第二壳体固接并连通有导管,所述导管密封滑动设置有滑动推杆,所述导管和所述滑动推杆均设置有安装单向阀的圆孔,所述第二壳体固接有第一动力件。本发明通过第一动力件的工作,驱动月池内海水缓慢旋转,旋转造成的表面剪切流可破坏静水条件下形成的边界层,延缓冰晶成核所需的稳定低温界面形成,再配合第一壳体中滤网对碎冰的收集,确保下放测试设备的稳定与安全。
