상기와 같은 구성을 가진 본 발명의 바람직한 실시 예를 살펴보면 다음과 같다.Looking at the preferred embodiment of the present invention having the configuration as described above are as follows.

우선, 본 발명은 제철소 내의 압연실(1)에 설치하여 압연실(1)의 압연롤에서 철강을 가공하는 과정을 촬영할 수 있도록 도 5에서 도시된 바와 같이 압연실(1)의 벽면이나 천정에 한개 내지는 다수개로 하여 제철소 압연실 내부 감시카메라(30)를 설치한다.First, the present invention is installed in the rolling chamber (1) in the steel mill to be photographed the process of processing steel in the rolling roll of the rolling chamber (1) as shown in Figure 5 on the wall or ceiling of the rolling chamber (1) The monitoring camera 30 inside a steel mill rolling chamber is installed as one or many pieces.

그런 후, 상황실에서 모니터(도면에 도시되지 않음)를 통해 압연실(1)을 감시할 수 있도록 제철소 압연실 내부 감시카메라(30)에 일반적으로 사용하는 전용회선(도면에 도시되지 않음)을 연결하고, 영상조합기나 영상편집기(도면에 도시되지 않음)를 별도로 더 설치하도록 한다.Thereafter, a dedicated line (not shown) commonly used for monitoring camera 30 inside the steel mill rolling chamber is connected so that the rolling chamber 1 can be monitored through a monitor (not shown) in the situation room. In addition, a video combiner or an image editor (not shown in the drawing) may be further installed.

상기와 같이 설치가 완료되면 전원을 인가하여 상황실에서 압연실(1) 내부에서 압연롤에 의해 작업하는 과정을 실시간으로 볼 수 있게 된다.When the installation is completed as described above it is possible to see in real time the process of working by the rolling roll in the rolling chamber 1 in the situation room by applying power.

여기서 상기 제철소 내의 압연실(1)에는 철강을 가공하기 위해 압연롤에 열과 함께 압력을 가하여 철강을 가공하게 되며, 이로 인해 발생하는 열을 식히기 위해 냉각유를 이용하게 되는데, 이러한 압연실(1) 내의 환경에 의해 촬영시 시야 확보의 어려움 및 카메라의 고장이 많이 발생하곤 하였다.In this case, the rolling chamber 1 in the steel mill is subjected to pressure to the rolling rolls together with heat to process the steel to process the steel, and cooling oil is used to cool the heat generated thereby, such a rolling chamber 1 Difficulties in securing the field of view and camera failures were often caused by the internal environment.

이에 본 발명에서는 이러한 문제점을 해결하기 위해 도 7 내지 도 8에서 보는 바와 같이 렌즈(2)의 촛점(P)이 정확하게 핀홀하우징(10)의 촛점홀(12)에 형성될 수 있는 것을 사용함으로써, 직경(d)이 1 ∼ 2.5mm 밖에 안되는 촛점홀(12)을 통해서도 촬영이 가능하며, 특히 직경(d)이 작은 촛점홀(12)에 의해 압연실(1)에서 발생하는 수증기라던가 냉각유가 핀홀하우징(10) 내부에 유입되지 않기 때문에 렌즈(2)나 카메라(3)의 손상을 미연에 방지할 수 있다.Accordingly, in the present invention, in order to solve this problem, as shown in FIGS. 7 to 8, the focal point P of the lens 2 may be accurately formed in the focal hole 12 of the pinhole housing 10. Photographing is also possible through the focusing hole 12 having a diameter d of only 1 to 2.5 mm. In particular, the steam or cooling oil generated in the rolling chamber 1 by the focusing hole 12 having a small diameter d is a pinhole. Since it does not flow into the housing 10, damage to the lens 2 or the camera 3 can be prevented in advance.

또한, 핀홀하우징(10)의 압축공기홀(13)에 연결되어 있는 압축공기관(22)과 상기 압축공기관(22)과 연결되어 있는 압축공기 생성부(21)로 이루어진 냉각부(20)에서 생성된 압축공기가 핀홀하우징(10) 내부에 유입되어 렌즈(2)나 카메라(3)를 냉각시킴으로써 열로부터 렌즈(2)나 카메라(3)를 보호할 수 있다.In addition, the cooling unit 20 is composed of a compressed air engine 22 connected to the compressed air hole 13 of the pinhole housing 10 and a compressed air generator 21 connected to the compressed air engine 22. The compressed air is introduced into the pinhole housing 10 to cool the lens 2 or the camera 3, thereby protecting the lens 2 or the camera 3 from heat.

아울러, 상기 핀홀하우징(10) 내부에 유입되는 압축공기는 촛점홀(12)을 통해 외부로 분사되면서 제철소 압연실 내부 감시카메라(30)의 시야확보를 할 수 있도록 작용한다.In addition, the compressed air flowing into the pinhole housing 10 serves to secure the field of view of the monitoring camera 30 inside the steel mill rolling room while being injected to the outside through the focus hole 12.

이를 상세히 설명하면, 일반적으로 압연실(1) 내부에는 전술한 바와 같은 수 증기, 냉각유 등에 의해 시야 확보를 함에 있어 어려움이 있었다.In detail, the rolling chamber 1 generally has a difficulty in securing a field of view by water vapor, cooling oil, or the like as described above.

하지만 본 발명에서는 핀홀하우징(10)의 촛점홀(12)로 압축공기를 분사시킬 수 있는 구조로 형성되어 있기 때문에 본 발명의 제철소 압연실 내부 감시카메라(30)가 촬영하고자 하는 일정범위 내에 수증기나 냉각유 기타 이물질이 압축공기의 분사에 의해 제거되면서 시야 확보를 할 수 있으며, 특히, 압축공기의 분사로 인해 핀홀하우징(10) 내부로 수증기나 냉각유 및 기타 이물질이 내부로 유입되지 않도록 작용하여 카메라(3)를 보호함과 동시에 원활한 시야 확보가 이루어지기 때문에 별도의 장비를 구비하지 않더라도 압연실(1) 내부를 잘 촬영하여 압연실(1) 내부의 감시를 효율적으로 할 수 있게 되는 것이다.However, in the present invention, since the compressed air is injected into the focusing hole 12 of the pinhole housing 10, the steel sheet rolling chamber internal monitoring camera 30 according to the present invention has steam or Cooling oil and other foreign matter is removed by the injection of compressed air to ensure visibility, in particular, by the injection of compressed air to prevent water vapor or cooling oil and other foreign matter from entering the inside of the pinhole housing (10) Since the camera 3 is protected and a smooth field of view is secured, the inside of the rolling chamber 1 can be efficiently photographed by monitoring the inside of the rolling chamber 1 even without a separate equipment.

상술한 실시예는 본 발명의 가장 바람직한 예에 대하여 설명한 것이지만, 상기 실시예에만 한정되는 것은 아니며, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 다양한 변형이 가능하다는 것은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어서 명백한 것이다.Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above embodiments, and various modifications are possible within the scope without departing from the technical spirit of the present invention. It is evident to those who have knowledge of.

상기에서 살펴본 바와 같이 본 발명의 제철소 압연실 내부 감시카메라는 핀 홀하우징 내부에 형성된 렌즈의 촛점이 핀홀하우징의 촛점홀에 촛점이 형성되도록 렌즈를 가공하여, 지름이 작은 촛점홀에 의해서도 압연실 내부의 촬영이 가능하여 촛점홀로 이물질이 유입되지 않아 카메라를 보호할 수 있다.As described above, the monitoring camera inside the steel mill rolling chamber of the present invention processes the lens so that the focal point of the lens formed inside the pinhole housing is focused on the focal hole of the pinhole housing. The camera's camera can be protected because foreign materials do not flow into the focus hole.

또한, 핀홀하우징 내부에 압축공기를 유입시켜 내부의 렌즈 및 카메라를 보호함과 동시에 촛점홀로 압축공기가 분사될 수 있도록 경사면을 형성하여, 일정거 리에 형성된 압연실 내부의 수증기 및 기름 유입을 차단함과 동시에 시야 확보를 용이하게 할 수 있어, 카메라의 보호 및 압연실 내부를 효율적으로 감시할 수 있는 유용한 발명이다.In addition, the compressed air is introduced into the pinhole housing to protect the lens and the camera inside, and at the same time, the inclined surface is formed so that the compressed air can be injected into the focus hole to block the inflow of water vapor and oil in the rolling chamber formed at a certain distance.
