The invention discloses a door-free weather-tight shutter with fireproof and electromagnetic shielding functions, which comprises a frame, an insect-proof and rat-proof net is arranged on the front side in the frame, a shutter structure and a multi-layer high-shielding waveguide structure which are positioned behind the insect-proof and rat-proof net are further arranged in the frame, and the shutter structure comprises a plurality of blades which are uniformly arranged up and down; a plurality of fireproof sealing strips are fixed to the frame, and when the shutter is closed, each fireproof sealing strip can seal a gap between every two adjacent blades. By arranging the multi-layer high-shielding waveguide structure and conducting fireproof treatment on the positions of the blades of the shutter, effective ventilation of the interior of a cabin is guaranteed, meanwhile, fireproof, electromagnetic shielding and wind and rain prevention are achieved, and therefore the diversified function requirements of the door-free wind and rain tight shutter in the ship ventilation field are met.
本发明公开了一种具有防火及电磁屏蔽功能的无门风雨密百叶窗,包括框架,框架内前侧设有防虫防鼠网,框架内还设有位于防虫防鼠网后方的百叶结构和多层高屏蔽波导结构,百叶结构包括多个上下均匀排列的叶片,框架上固定有多个防火密封条,在百叶窗关闭时,每个防火密封条能封闭一个相邻两叶片之间的缝隙。本发明通过设置多层高屏蔽波导结构,以及对百叶窗叶片位置进行防火处理,在保证舱室内部有效通风的同时,实现防火、电磁屏蔽以及防风雨,从而满足船舶通风领域无门风雨密百叶窗多样化功能需求。
