Zusammenfassung: | According to an aspect of the present invention, provided is a flood-proof vent that is installed on a hull and has a ventilation pipe through which air flows, and blocks the intrusion of seawater to prevent flooding. The flood-proof vent comprises: an air chamber for reducing the flow rate of the vent; a water catcher positioned adjacent to the air chamber and removing scattered seawater; a bent pipe having one end connected to the air chamber, the other end connected to an opening through which the vent communicates with the outside, and having a flow path in the shape of L; and a buoyancy damper provided at the other end of the bent pipe to open or block the opening depending on whether it is submerged.
본 발명의 일 측면에 따르는 침수 방지형 통풍구는 선체에 설치되어 공기가 유동하는 통풍관을 구비하며, 해수의 침입을 차단하여 침수를 방지하는 침수 방지형 통풍구로서, 상기 통풍구의 유속을 감소시키는 에어챔버; 상기 에어챔버와 인접하도록 위치하며, 비산된 해수를 제거하는 워터캐쳐; 일단부는 상기 에어챔버와 연결되고, 타단부는 상기 통풍구가 외부와 연통하는 개구부에 연결되며, ㄱ 형상으로 굽혀진 유로를 갖는 굽힘관; 및 상기 굽힘관의 타단부에 구비되며 침수 여부에 따라 상기 개구부를 개방 또는 차단시키는 부력댐퍼를 포함한다. |
