The invention provides a hollow device for reducing additional resistance of a moon pool, which comprises a ship body provided with the moon pool, a concave guide surface is arranged at the bottom of the ship body on one side of a bottom opening of the moon pool close to the advancing direction, and the guide direction faces the bottom of the moon pool. A streamline guide surface is arranged at the bottom of the ship body in front of the moon pool, so that water flow passing through the upstream is redirected to the position below the bottom of the moon pool to the maximum extent by means of the inward concave shape, the effect of reducing flow exchange between the moon pool and an external area is achieved, and the effect of reducing the resistance of the moon pool is achieved.

    本发明提供一种用于减小月池附加阻力的空心装置,包括设置有月池的船体,在月池底部开口靠近行进方向一侧的船体底部设置有内凹的引导面,且引导方向朝向月池的底部。本发明在月池前方的船体底部设置流线型引导面,从而利用内凹的形状使上游通过的水流最大程度的向月池底部的下方进行重定向,实现减少月池与外部区域之间流量交换的效果,达到降低月池阻力的效果。
