The invention relates to a water curtain device of a marine LNG (Liquefied Natural Gas) filling station for LNG leakage protection. The water curtain device comprises a structural part, a pipe frame and a water curtain pipe, the structural part is arranged on the side of the ship body and hinged to the pipe frame. The water curtain pipe is horizontally fixed on the pipe frame and can overturn around the structural member along with the pipe frame, so that the water curtain pipe can be in two states of extending out of the broadside and retracting to the broadside; the water curtain pipe is provided with at least one row of strip-shaped open holes in the length direction of the water curtain pipe, and the strip direction of the strip-shaped open holes is also in the length direction of the water curtain pipe. Round open holes of the water curtain pipe are optimized to be strip-shaped open holes, so that the water curtain pipe is not prone to being blocked, the area, covering the outer plate, of the water curtain is increased, and potential safety hazards are reduced; compared with a water curtain pipe with a circular hole, the water curtain pipe with the strip-shaped hole is more convenient to manufacture; the water curtain pipe is made into a storable type, is placed outside the ship during working, and is recovered in the ship in a non-working state, so that the ship width is not increased, and the attractiveness is not influenced.

    本发明涉及一种用于LNG泄露保护的船用LNG加注站的水帘装置,包括结构件、管架、水帘管;结构件设于船体舷侧,管架与结构件铰接;水帘管水平地固定在管架上,并可随管架一同绕结构件翻转,使之可处于伸出舷侧和收回舷侧两种状态;水帘管上设有至少一排沿水帘管长度方向的条状开孔,条状开孔的长条方向也沿水帘管长度方向。本发明将水帘管的圆形开孔优化为条形开孔,使得水帘管不易堵塞,且增加了水帘覆盖到外板的面积,减小了安全隐患;条形开孔的水帘管相比圆形开孔的制造更为方便;将水帘管做成可收纳式的,工作时放在船外,非工作状态即回收于船内,不会增加船宽,也不影响美观。
