The present invention relates to a housing for an air-cooled camera, and more particularly, the cooling air injected into the interior of the housing is introduced through a plurality of inflow holes formed in the upper portion of the cap installed on the front of the housing, By spraying in the direction to discharge through the discharge port formed in the lower portion of the cap to prevent the foreign matter such as dust or dust adhered to the observation glass mounted on the rear of the cap, and at the same time the flame caused by radiant heat and soot and steam by steam It relates to a housing for an air-cooled camera to block the.

일반적으로 용광로나 전기로에서 나오는 선철은 고온 상태이므로 선철이 이송되는 이송로 주변이나 로 내부의 온도 역시 매우 높게 유지되기 때문에 이송과정에서 발생할 수 있는 이상 유무를 작업자가 근접하여 인위적으로 감시하는 것이 곤란하므로 이송로 주변이나 로 내부의 적정위치에 원격조정 카메라를 내장한 하우징을 설치하여 원격?감시토록 하고 있다.In general, pig iron from the blast furnace or electric furnace is in a high temperature state, so the temperature around the inside of the furnace and inside of the furnace is also kept very high. Remote monitoring is provided by installing a housing with a remote control camera at a suitable location around the transport path or inside the furnace.

이러한 경우 상기 하우징이 직접 열을 받아 가열됨에 따라 이를 그대로 방치하면 하우징은 물론 내장된 카메라 역시 쉬 훼손되는 문제가 발생하므로, 종래에는 하우징을 냉각시켜 주기 위해 상기 하우징의 전면에 착설된 캡의 내부에 냉각공기를 주입시켜 상기 냉각공기가 전면부를 냉각시켜줌과 동시에 캡의 중앙부에 개구된 유통구를 통해 전방으로 분사되면서 상기 유통구를 통한 이물질의 유입을 방지토록 하고 있다.In this case, since the housing is directly heated to heat and left as it is, the housing as well as the built-in camera may also be damaged. Thus, in order to cool the housing, the inside of the cap installed on the front of the housing is conventionally used. Cooling air is injected to cool the front part, and at the same time, the cooling air is injected forward through the outlet opening in the center of the cap to prevent the inflow of foreign substances through the outlet.

그러나 상기 하우징의 캡을 통해 분사된 냉각공기는 유통구를 따라 선회하게 되므로 먼지나 분진 등의 이물질이 상기 캡의 후면에 착설된 관찰유리에 부착되는 것을 효과적으로 방지하지 못할 뿐더러 상기 관찰유리의 전면에 이물질이 점차 퇴적되어 카메라의 시야를 차단하는 심각한 문제점이 있었다.However, since the cooling air injected through the cap of the housing is pivoted along the distribution port, it does not effectively prevent foreign matter such as dust or dust from adhering to the observation glass installed on the rear of the cap. There was a serious problem that the foreign matter is gradually deposited to block the view of the camera.

또한, 상기 캡의 유통구를 통해 냉각공기가 분사되더라도 관찰유리의 전면에 발생하는 복사열에 의한 화염 및 그을음과 수증기에 의한 김서림을 완전하게 차단하지 못하므로 관찰유리의 파손을 야기하는 문제점이 있었다.
In addition, even though cooling air is injected through the outlet of the cap, there is a problem of causing damage to the observation glass because it does not completely block the flame caused by the radiant heat generated on the front surface of the observation glass, and the mist of soot and steam.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 하우징의 내부로 주입된 냉각공기가 상기 하우징의 전면에 착설된 캡의 상부에 형성된 다수의 유입공을 통해 유입된 후 유도턱에 의해 하방향으로 분사되어 상기 캡의 하부에 형성된 배출구를 통해 배출되도록 함으로써 상기 캡의 후방에 착설된 관찰유리에 먼지나 분진 등의 이물질이 부착됨을 방지함과 동시에 복사열에 의한 화염 및 그을음과 수증기에 의한 김서림을 차단할 수 있도록 하는 공랭식 카메라용 하우징을 제공하는 데 그 목적이 있다.
