Disclosed is an LNG cargo tank having a leakage detection apparatus. According to an embodiment of the present invention, the LNG cargo tank having a leakage detection apparatus comprises: a main body unit (110) having three or more blade guide frames (120) mounted to form an equilateral polygonal shape when viewed from above, an image recognition device (130) mounted on an upper surface or a lower surface thereof, and a control unit (170) embedded therein; a sensor moving belt (140) provided with a gas detection sensor (150) mounted on an outer surface thereof, and mounted to be moved along outer circumferential surfaces of the blade guide frames (120); a detection device suction fixing unit (160) mounted on one side of the main body unit (110) and attached to a surface (1) of a detection target by a suction pressure; and the control unit (170) to receive a control signal supplied from an operator to control operation of an leakage detection apparatus (100), and transmit gas detection information detected from the gas detection sensor (150) and image information acquired from the image recognition device (130) to the operator. According to the LNG cargo tank having a leakage detection apparatus, gas leakage detection work for a high point can be easily performed in a cargo tank test.

    누설 탐지장치를 갖는 LNG 화물창이 개시된다. 본 발명의 실시예에 따른 누설 탐지장치를 갖는 LNG 화물창은, 셋 이상의 블레이드 가이드 프레임(120)을 평면상 정다각형 배치를 이루도록 장착하고, 상부면 또는 하부면에 영상인식장치(130)를 장착하며, 내부에 제어부(170)를 내장하는 본체부(110); 외부면에 가스탐지센서(150)가 장착되고, 블레이드 가이드 프레임(120)의 외주면을 따라 이동 가능하도록 장착되는 센서이동벨트(140); 본체부(110)의 일측부에 장착되고, 흡착압력에 의해 탐지대상 표면(1)에 부착되는 탐지장치 흡착 고정부(160); 운용자로부터 제공되는 제어신호를 수신하여 누설 탐지장치(100)의 작동을 제어하고, 가스탐지센서(150)로부터 검출된 가스검출정보 및 영상인식장치(130)로부터 획득한 영상정보를 운용자에게 전송하는 제어부(170);를 포함하는 내부누설장치를 갖는 것을 요지로 한다. 본 발명의 누설 탐지장치를 갖는 LNG 화물창에 따르면, 카고 탱크 테스트(Cargo tank test)에 있어서 높은 지점에 대한 가스 누설 탐지작업을 손쉽게 실시할 수 있는 누설 탐지장치를 갖는 LNG 화물창을 제공할 수 있다.
