Anti-rolling water tank and ship

The stabilization water tank comprises a water tank shell with one end open and a plurality of damping plates, and the two ends of each damping plate are arranged on the two opposite side walls in the water tank shell respectively in a sliding mode. A locking assembly used for locking the relative position of the damping plate on the water tank shell is arranged between the damping plate and the water tank shell, and a plurality of through holes are formed in the damping plate. The anti-rolling device is simple in structure, easy to repair and maintain, good in economical efficiency and applicability, small in occupied ship space and capable of achieving the anti-rolling effect at all navigational speeds. 本实用新型提供了一种减摇水舱及船舶，其中减摇水舱包括一端开口的水舱外壳和若干阻尼板，阻尼板的两端分别滑动设置在水舱外壳内相对的两侧壁上，阻尼板和水舱外壳之间设有用于锁定阻尼板在水舱外壳上的相对位置的锁定组件，阻尼板上开设有若干通孔。本实用新型结构简单，易于维修保养，经济型和应用性较好，并且占用船舶空间较小，能够在所有航速下都具有减摇效果。
