도 1은 본 발명의 일 실시예에 따른 수소가스의 누설 부위 검출 장치를 설명하기 위한 개념도, 도 2는 본 발명의 일 실시예에 따른 수소가스의 누설 부위 검출 방법의 구성도이다.1 is a conceptual diagram for explaining an apparatus for detecting a hydrogen gas leakage portion according to an embodiment of the present invention, and FIG. 2 is a configuration diagram of a method for detecting a hydrogen gas leakage portion according to an embodiment of the present invention.
도 1에 도시된 바와 같이 본 발명에 의한 수소가스의 누설 부위 검출 장치는 통상의 파이프와 같은 몸체(10)의 하단에 붓의 털을 원주형으로 붙여 놓은 것과 같이 털 하나하나의 표면에 수소가스를 만나면 화학적으로 변색되는 액체를 도포 또는 도장한 것을 접착시킬 수 있다.As shown in FIG. 1, the hydrogen gas leak detection device according to the present invention is similar to attaching the hair of a brush to the lower end of the body 10, such as a normal pipe, in a cylindrical shape. It is possible to attach a liquid that is chemically discolored when it meets or is coated with it.
몸체(10)의 원형 파이프 단면에 솔(Brush)이 다수 부착되어있는 형태가 될 수 있으며, 이는 칫솔이 원형으로 되어 있는 것과 같은 형태의 검출수단(20)이 되되, 몸체(10) 및 검출수단(20)의 형태는 이에 한정되지 아니하며 몸체(10)에서의 검출수단(20)의 부착 위치는 조정할 수 있다.The body 10 may have a shape in which a plurality of brushes are attached to the cross section of the circular pipe, which becomes the detection means 20 in the same shape as that of a toothbrush, the body 10 and the detection means The shape of (20) is not limited thereto, and the attachment position of the detection means (20) in the body (10) can be adjusted.
솔 형태의 검출수단(20)의 일측은 수소가스 누설 부위에 접촉할 수 있다.One side of the brush-shaped detection means 20 may contact the hydrogen gas leakage site.
이러한 솔 형태의 검출수단(20)을 수소가스 누설 부위를 향하여 누르면서 이동시키면 몸체(10)의 원통 내외부로 휘어진 솔, 즉 칫솔의 솔을 눌렀을 때 솔이 ㄴ(니은)자로 구부러지게 되고, 수소가스 누설 부위와 접촉하게 되는 구부러진 솔의 부분은 원통의 원주 부위를 벗어나므로 원통형인 몸체(10) 안팎으로 보일 수 있다.When the brush-shaped detection means 20 is moved while pressing toward the hydrogen gas leakage site, the brush bent into and out of the cylinder of the body 10, that is, when the brush of the toothbrush is pressed, the brush is bent into an L-shape, and hydrogen gas leakage The part of the bent brush that comes into contact with the part is outside the circumference of the cylinder, so it can be seen in and out of the cylindrical body 10 .
이러한 솔의 형태로 미세하게 누설되는 수소가스를 감지할 수 있으며 그보다 큰 수소가스의 누설이 발생하는 부위를 찾아낼 수 있다.In the form of such a brush, it is possible to detect a small leak of hydrogen gas, and it is possible to find a location where a larger leak of hydrogen gas occurs.

System), it is possible to determine whether the input image contains the discoloration state of the brush, and take action to inform that a leak is occurring.
