The invention relates to the technical field of marine shutters, and discloses a marine noise reduction shutter which comprises a window frame, a plurality of inner blades are distributed in the window frame at equal intervals, the two sides of each inner blade are rotationally connected with the inner side wall of the window frame through connecting shafts, and first cavities are formed in the bottom ends of the interiors of the inner blades; and each cavity I is filled with a sound absorption plate. Through mutual cooperation of the opening and closing mechanism and the gas flowing assembly, in the opening and closing process of the shutter, the gas content in the miniature air cylinder is synchronously controlled, when the shutter is closed, the bottom ends of the outer blades shield a closed gap between the upper inner blade and the lower inner blade, outer layer sealing of the inner blades is achieved, and the service life of the shutter is prolonged. And meanwhile, when the louver is in a closed state, the sealing gasket can be automatically protected so as to reduce sea wind erosion on the sealing gasket, and meanwhile, by means of dislocation between the through holes and the connecting holes, protection on the acoustic board is synchronously achieved.

    本发明涉及船用百叶窗技术领域,公开了一种船用降噪百叶窗,包括窗框,所述窗框的内部等间距分布有多个内叶片,且每个内叶片的两侧均通过连接轴与窗框的内侧壁转动连接,所述内叶片内部的底端均开设有空腔一,且空腔一的内部均填充有吸音板。本发明通过启闭机构与气体流动组件之间的相互配合,使百叶窗在启闭过程中,同步控制微型气筒内部的气体含量,使百叶窗在闭合时,外叶片的底端对上下两个内叶片之间的闭合缝隙进行遮挡,实现对内叶片的外层密封,同时使百叶窗在闭合状态时能够自动对密封垫进行防护,以减少密封垫受到的海风侵蚀性,同时利用通孔与连接孔之间的错位,同步实现对吸音板的防护。
