An embodiment of the present invention relates to a nozzle device for extinguishing a fire, which is installed on a helideck or in a helicopter landing area. Provided is a nozzle device comprising: a piston formed in a cylindrical shape with a top and a bottom opened, and including a plurality of piston holes arranged on an outer circumference surface to spray, to the outside, water introduced inside through a water supply pipe; a nozzle connected to the upper part of the piston to increase or reduce the entire length, and including rotation holes, which are arranged on an outer circumference surface to spray water to the outside while generating a rotational force using the water transmitted through the piston, and a nozzle spray holes for allowing water to be sprayed toward an upper part or a side part; and a nozzle head coupled to the upper end of the nozzle to cover the tops of the nozzle spray holes when the nozzle device for extinguishing a fire does not operates. Therefore, provided is a nozzle device for extinguishing a fire, wherein the horizontal reach and vertical reach of sprayed fire-extinguishing water are excellent, and fire-extinguishing water can be emitted even when a nozzle cannot protrude.

    본 발명의 일실시예는 헬리데크(Helideck) 또는 헬리콥터 착륙지역에 설치되는 소방용 노즐장치에 있어서, 상하가 개구된 원통 형상으로 형성되고, 급수관을 통해 내부로 유입되는 물이 외부로 분사하기 위해 외주면 상에 마련되는 복수개의 피스톤 홀들을 포함하는 피스톤과, 상기 피스톤의 상부에 연결되어 전체 길이를 신장시키거나 축소시키며, 상기 피스톤을 통해 전달되는 물에 의해 회전력을 발생하면서 물을 외부로 분사하기 위해 외주면 상에 마련되는 로테이션 홀들과, 상부 또는 측부를 향해 물이 분사되도록 하는 노즐 분사 홀들을 포함하는 노즐과, 상기 노즐의 상단에 결합되어, 상기 소방용 노즐장치가 미작동 시에 상기 노즐 분사 홀들의 상부를 커버하는 노즐 헤드를 포함하는 소방용 노즐장치를 제공한다.
