The invention provides a ship bubble drag reduction device and a drag reduction method, and belongs to the technical field of ship drag reduction. The device comprises a mounting frame, an air box, a hydrofoil plate, a driving mechanism and a plugging mechanism, the mounting frame is fixedly arranged on the inner side of a mounting hole, a mounting cavity is formed in the mounting frame, an air pipe is connected to the bottom of the mounting frame, the air box is arranged in the mounting cavity in an up-down sliding mode, and a telescopic hose is connected between the air box and the bottom of the mounting frame. A plurality of second air holes are formed in the lower side face of the air box, the hydrofoil plate is horizontally and fixedly arranged below the air box, the length direction of the hydrofoil plate is consistent with the length direction of the mounting hole, the driving mechanism can drive the air box to move up and down, and the blocking mechanism can block the second air holes. The pressure of the bubble outlet can be reduced, backward movement of bubbles is accelerated, the bubble layer can cover the whole ship body bottom plate, the ship drag reduction effect is improved, and energy consumption is further reduced.

    本发明提供了一种船舶气泡减阻装置及减阻方法,属于船舶减阻技术领域。本发明包括安装框、空气盒、水翼板、驱动机构和封堵机构,所述安装框固设在安装孔的内侧,所述安装框内设有安装腔,所述安装框的底部连接有空气管,所述空气盒上下滑动设置在安装腔内,所述空气盒和安装框底部之间连接有伸缩软管,所述空气盒的下侧面开设有若干个第二透气孔,所述水翼板水平固设在空气盒的下方,所述水翼板的长度方向和安装孔的长度方向一致,所述驱动机构能够带动空气盒上下移动,所述封堵机构能够将若干个第二透气孔都封堵起来。本发明能够降低气泡排出口的压力,加速气泡向后移动,使气泡层可以覆盖整个船体底板,提高船舶减阻效果,进一步降低能耗。
