The invention discloses a marine gooseneck ventilator and a ship, the marine gooseneck ventilator comprises a gooseneck ventilator body and a self-sealing structure, and the gooseneck ventilator body is provided with a first connecting part; one axial end of a connecting cylinder of the self-closing structure is in sealed connection with the first connecting part, the other end of the connecting cylinder is hinged to a sealing cover, the sealing cover is used for opening or closing an opening of the connecting cylinder, the self-closing assembly comprises a self-closing piece arranged in the connecting cylinder, and the self-closing piece is configured to have a first working position where the connecting cylinder and the gooseneck ventilator body are disconnected; and the buoyancy of seawater can drive the self-sealing piece to move from the second working position to the first working position. When the water level of the seawater is higher than the first working position of the self-sealing piece, the seawater can be prevented from flowing into the cabin from the gooseneck ventilator body, and when the water level of the seawater is lowered below the second working position of the self-sealing piece, air in the cabin can interact with external air again.

    本发明公开了船用鹅颈通风筒和船舶,船用鹅颈通风筒包括鹅颈通风筒本体和自封闭结构,鹅颈通风筒本体设有第一连接部;自封闭结构的连接筒沿轴向的一端与第一连接部密封连接,另一端与封盖铰接,封盖用于打开或封闭连接筒的开口,自封闭组件包括设置于连接筒内的自封闭件,自封闭件被配置为具有断开连接筒和鹅颈通风筒本体的第一工作位置,以及连接筒和鹅颈通风筒本体的第二工作位置,海水的浮力能带动自封闭件由第二工作位置移动至第一工作位置。当海水的水位高于自封闭件的第一工作位置时,能避免海水由鹅颈通风筒本体流入舱室内,当海水的水位下降至自封闭件的第二工作位置以下时,舱室内的空气能够重新与外界的空气进行交互。
