Background

In order to improve the quality of life of passengers and crews, swimming pools are arranged on a plurality of ships; especially large cruise ships, usually have several swimming pools. Since the surface of the swimming pool is open, a free liquid surface is formed, which may reduce the stability of the ship. When the ship encounters severe sea conditions, the ship can generate rolling motion, and the water in the swimming pool can also roll along with the rolling motion of the ship, so that the rolling motion of the ship is intensified, and the safety of the ship is even seriously influenced.

In the prior art, if a large-wave sea condition is met, the swimming pool water can be completely discharged into the sea or other water tanks. However, due to the large number of swimming pools, the large volume of water, and for sanitary reasons, the swimming pool water is not usually filled into other tanks, but is discharged directly into the sea. From an economic perspective, the swimming pool water is fresh water, generally supplied onshore or generated by a water generator, which is very costly and can be discharged into the sea with great waste if exposed to high wind and waves. Some ships are provided with special anti-rolling tanks to reduce the rolling of the ships, but the operation is not suitable for the cruise ship because the internal space of the cruise ship is precious and the special anti-rolling tanks are rarely arranged.
