The invention relates to the technical field of ships, in particular to a ship water tank and a ship. The ship water tank comprises a first water tank body, a second water tank body and a pipeline assembly, and the first water tank body is arranged on the peripheral side of a stern shaft of a ship in a surrounding mode and used for cooling the stern shaft; the second water tank is located above the first water tank and used for containing ballast water. The pipeline assembly is used for connecting the first water tank and the second water tank so that ballast water in the second water tank can enter the first water tank. The ship water tank has the following advantages that the first water tank has the cooling effect on the ship tail shaft, normal work of the tail shaft is guaranteed, and the service life of the tail shaft is prolonged; the second water tank has the effect of a stern water ballast tank and can be used for adjusting the gravity center position, the floating state and the stability of the ship so as to solve the problem that the stability of the ship is insufficient due to oil and water consumption and gravity center rising in the sailing process. In this way, ballast water in the second water tank can enter the first water tank, a water supply pipeline system does not need to be arranged in the first water tank, equipment expenditure is saved, and cost is reduced.

    本发明涉及船舶技术领域,尤其涉及一种船舶水舱及船舶。所述船舶水舱包括第一水舱、第二水舱和管路组件,第一水舱围设于船舶的艉轴周侧,用于冷却艉轴;第二水舱位于第一水舱的上方,用于容置压载水;管路组件用于连接第一水舱和第二水舱,以使第二水舱内的压载水能够进入第一水舱内。该船舶水舱具有以下优点:第一水舱具有冷却船舶艉轴的冷却效果,保证艉轴正常工作,延长艉轴的使用寿命;第二水舱具有艉部压载水舱的作用,可用于调整船舶的重心位置、浮态和稳性,以解决船舶在航行过程中因油水消耗、重心升高而导致稳定性不足的问题;第二水舱内的压载水能够进入第一水舱内,而无需在第一水舱内设置供水管路系统,节省设备开支,降低成本。
