The invention discloses a large flow guide moon pool structure capable of reducing sailing resistance. The large flow guide moon pool structure comprises a moon pool body, and a connecting assembly is fixedly connected with the moon pool body; the end, away from the moon pool body, of the first drainage plate is rotationally connected with the fixing block, the other end of the first drainage plate is connected with the connecting assembly, and the connecting assembly drives the first drainage plate to open and close relative to the horizontal plane to adjust the included angle between the first drainage plate and the horizontal plane; the second drainage plate is arranged on the outer side of the first drainage plate, the end, away from the moon pool body, of the second drainage plate is rotationally connected with the fixing block, the other end of the second drainage plate is connected with an opening and closing supporting structure, and the opening and closing supporting structure drives the second drainage plate to conduct opening and closing movement relative to the horizontal plane to adjust the included angle between the second drainage plate and the first drainage plate. Through cooperation of the first drainage plate, the second drainage plate, the connecting assembly and the opening and closing supporting structure, vortexes formed when fluid passes through the rear wall of the moon pool body are reduced or avoided, a flow field is smoother, and then the water flow resistance borne by the moon pool body is reduced.

    本发明公开了一种可减少航行阻力的大型导流月池结构,包括月池本体,连接组件与月池本体固定连接;引流板一,引流板一远离月池本体的一端与固定块转动连接,另一端与连接组件连接,连接组件驱动引流板一相对于水平面发生张合运动调节引流板一与水平面之间的夹角;引流板二,引流板二设置在引流板一外侧,其远离月池本体的一端与固定块转动连接,其另一端连接张合支撑结构,张合支撑结构驱动引流板二相对于水平面发生张合运动调节引流板二与引流板一之间的夹角。本发明通过引流板一、引流板二、连接组件和张合支撑结构之间的配合,达到了减少或避免流体经过月池本体后壁形成的旋涡,使流场更加顺畅,进而降低月池本体受到的水流阻力。
