본 발명은 원자력 발전소의 고방사능 지역에 설치되는 체크밸브, 게이트 밸브의 시트링의 상태를 촬영하여 표면의 상태를 육안으로 관찰 할 수 있도록 장치에 관한 것이다.The present invention relates to a device that can visually observe the state of the surface by photographing the state of the seating of the check valve, the gate valve installed in the high radiation area of the nuclear power plant.

발전기 시스템에 사용되는 각종 밸브는 고온과 고압상태를 유지하므로 주기적으로 밸브와 시트링의 상태를 점검하여 안전사고에 대비하고, 정비방향을 결정하여야 한다.Since various valves used in the generator system maintain high temperature and high pressure, it is necessary to periodically check the valve and seating ring to prepare for safety accidents and to determine the maintenance direction.

종래에는 밸브의 상태를 점검하기 위하여 육안으로 관찰하고 판단하므로 인하여 관찰하는 사람마다 개인별로 판단이 다를 수 있으므로 일관성 있게 작업하기 어려운 문제점이 있었다.Conventionally, since the observation and judgment by the naked eye to check the state of the valve, there is a problem that it is difficult to work consistently because the judgment can be different for each person to observe.

이러한 문제점을 해소하기 위하여 화이버 옵티칼 카메라(Fiber Optical Camera)를 사용하여 밸브시트링을 촬영하여 이를 모니터에서 확인하는 작업을 하였으나 이러한 기존의 화이버 옵티칼 카메라는 촬영하고자 하는 위치에 팁을 삽입하고 팁의 전면에서 보이는 부분을 촬영하므로써 정확도를 높일 수 있으나 사용중에 팁의 오염되는 경우가 많아 정확하게 촬영하기 어려운 문제점이 있으며, 또한 팁의 위치를 고정하기가 곤란하여 결함부위를 정확히 찾아내기 어려운 문제점이 있었다.In order to solve this problem, the valve seating was taken by using a fiber optical camera and the valve seating was taken and checked on the monitor. However, in the conventional fiber optical camera, a tip is inserted at a desired location and the front of the tip is inserted. It is possible to increase the accuracy by taking the visible part, but there is a problem that the tip is often contaminated during use, it is difficult to accurately shoot, and also difficult to pinpoint the location of the tip has a problem that it is difficult to pinpoint the defect.

또한 촬영할 때의 해상도, 조명 및 촬영한 각도가 다르므로 비교가 어려운 문제점이 있었다.In addition, since the resolution, lighting and the shooting angle when shooting was different, there was a difficult problem.

본 발명은 상기와 같은 문제점을 해소하기위하여 안출한 것으로 동일한 각도와 위치에서 촬영하여 사진의 크기가 항상 동일하게 하여 작업자가 판단을 정확히 할 수 있도록 함을 목적으로 한다.The present invention has been made in order to solve the above problems is to shoot at the same angle and position to ensure that the size of the picture is always the same so that the operator can make a precise decision.

본 발명의 또 다른 목적은 밸브 내부의 협소한 공간에서도 시트전체를 촬영할 수 있도록 하여 한번에 밸브의 상태를 체크할 수 있도록 하여 작업성을 향상시킬 수 있도록 함에 있다. Still another object of the present invention is to improve the workability by allowing the entire seat to be photographed even in a narrow space inside the valve so that the state of the valve can be checked at once.

상기 목적을 달성하기 위한 본 발명은 밸브에 착탈가능하게 설치되는 카메라 마운트와; 상기 카메라 마운트에 설치되는 카메라 베이스와; 상기 카메라베이스에 설치되는 카메라 및 조명기와; 상기 카메라의 렌즈로 상을 보내기 위하여 밸브내부 에 설치되어 전면을 비출 수 있는 구형(球形)밀러로 구성됨을 특징으로 한다.
The present invention for achieving the above object is a camera mount detachably installed on the valve; A camera base installed on the camera mount; A camera and an illuminator installed on the camera base; In order to send an image to the lens of the camera is installed in the valve is characterized in that it consists of a spherical (sphere) that can be illuminated on the front.

이하 본 발명의 실시예를 첨부된 도면을 참조하여 구성 및 작용효과를 상세히 설명하면 하기와 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail the configuration and effect.

우선 도 1을 참조하여 본 발명의 구성을 설명하면 밸브에 착탈가능하게 설치되는 카메라 마운트(10)와; 상기 카메라 마운트(10)에 설치되는 카메라 베이스(20)와; 상기 카메라베이스(20)에 설치되는 카메라(21) 및 조명기와; 상기 카메라(21)의 렌즈(23)로 상을 보내기 위하여 밸브내부에 진입되어 전면을 비출 수 있는 구형(球形)밀러(30)로 구성되며, 상기 카메라 마운트(10)는 하부의 베이스(11)로부터 카메라 베이스(20)를 상하로 이동할 수 있도록 지지하는 지지대(13)와, 상기 베이스(11)의 전면에 설치되며, 밸브의 내부로 진입하는 미러지지대(25)가 볼트(26)로 고정되고, 상기 밀러지지대(25)의 중앙에는 클립(32)으로 고정된 구형밀러(30)가 설치된다.First, the configuration of the present invention will be described with reference to FIG. 1 and a camera mount 10 detachably mounted to a valve; A camera base 20 installed on the camera mount 10; A camera 21 and an illuminator installed on the camera base 20; In order to send an image to the lens 23 of the camera 21 is composed of a spherical mirror (30) that can enter the inside of the valve to illuminate the front, the camera mount 10 is the base 11 of the lower base 11 A support 13 for supporting the camera base 20 so as to move up and down, and a mirror support 25 installed at the front of the base 11 and entering the inside of the valve, are fixed by bolts 26. In the center of the mirror support 25 is provided a spherical mirror 30 fixed with a clip (32).

또한 상기 지지대(13)의 홈(15)에는 카메라(21)가 고정된 카메라 베이스(20)의 T형 돌기(25)가 삽입되어 카메라 베이스(20)를 이동가능하게 고정할 수 있도록 설치되고, 상기 카메라 베이스(20)에는 카메라(21)의 렌즈(23)를 홀더(26)로 고정시키며, 조명등을 구비한다. In addition, the groove 15 of the support 13 is inserted to the T-shaped projection 25 of the camera base 20 is fixed to the camera 21 is installed to be movable to fix the camera base 20, The camera base 20 fixes the lens 23 of the camera 21 with a holder 26 and includes a lamp.

위와 같이 구성되는 본 발명은 밸브의 내부를 촬영하기 위하여서는 밸브(40)의 본네트를 열고 내장품을 제거하고, 본네트의 가스켓을 제거한다.The present invention configured as described above to open the bonnet of the valve 40 to remove the internals, to remove the gasket of the bonnet in order to photograph the inside of the valve.

이후 밸브몸체위에 남아 있는 방사능물질을 깨끗이 청소한 후 밸브(40) 안쪽에 남아 있는 물을 닦아낸다.After cleaning the remaining radioactive material on the valve body and then wipe the remaining water inside the valve (40).

우선 카메라 마운트(10)의 베이스(11)에 밀러지지대(25)를 고정볼트(26)를 이용하여 고정하고 카메라 마운트의 홈(15)에 카메라베이스(20)의 후방의 T형 돌기(25)를 맞추어 조립한 후 밀러지지대(25)가 밸브(40)의 내부로 들어가도록 하여 중앙에 설치된 밀러가 밸브(40)의 내부에 설치된 시트링(42) 부위를 반사할 수 있는 상태로 카메라 마운트를 밸브의 일측에 플렉시블 핀(18)을 이용하여 부착시킨다. 이는 카메라 마운트의 방향을 조절할 수 있도록 하기 위한 것이다.First, the support base 25 is fixed to the base 11 of the camera mount 10 using the fixing bolt 26, and the T-shaped protrusion 25 behind the camera base 20 in the groove 15 of the camera mount 20. After assembling the assembly, the mirror support 25 enters the inside of the valve 40 so that the center mounted mirror can reflect the seat ring 42 installed inside the valve 40. Attach to one side of the valve using a flexible pin (18). This is to allow the direction of the camera mount to be adjusted.

위와 같은 상태에서 카메라의 초점을 맞추어 촬영을 하면 촬영된 상을 모니터를 통하여 자료를 시각적으로 확인할 수 있는 상태가 되는 것으로 이를 보다 상세히 설명하면 도 4에 도시한 바와 같이 구형거울(30)이 밸브의 중앙에 위치한 상태이므로 밸브의 일측에 설치되는 시트링을 밸브의 내부에서 보는 것과 같이 구형거울에 비추여 반사되면 이를 카메라에서 촬영할 수 있게 된다.In the above state, when the camera focuses and photographs, the photographed image is visually checked through the monitor, which will be described in more detail. As shown in FIG. Since it is located in the center, the seat ring installed on one side of the valve can be photographed by the camera when it is reflected by a spherical mirror as seen from the inside of the valve.

위와 같이 촬영된 데이터를 화상복원프로그램을 이용하여 보정하게 되는데 이는 카메라에 촬영된 상이 구형거울에 의해 반사된 상이므로 구형면에 따라 왜곡된 상태이므로 구형거울에서 왜곡된 상을 보정하여 원래의 상으로 변환하여 모니터에서 시각적으로 확인할 수 있게 되는 것으로 화상복원프로그램에 대하여서는 상세한 설명을 생략한다. The data taken as above is corrected by using an image restoration program. Since the image taken by the camera is reflected by the spherical mirror, it is distorted according to the spherical surface, so it is corrected by the spherical mirror. The conversion can be confirmed visually on the monitor, and detailed description of the image restoration program is omitted.

또한 상기 과정에 의해 보정된 상의 데이터를 저장하여 추후에 시트링의 침식 진행상태를 예측할 수 있게 되어 예방정비가 가능해진다. In addition, by storing the data of the phase corrected by the above process it is possible to predict the progress of the erosion of the seating in the future it is possible to preventive maintenance.

또한 밸브시트링의 침식상태를 모니터에서 관찰하므로써 방사능 피폭을 저감할 수 있게 된다.In addition, the radiation exposure can be reduced by monitoring the erosion state of the valve seat ring on the monitor.

상기한 바와 같이 본 발명에 의하면 동일한 각도와 위치에서 촬영하여 사진의 크기가 항상 동일하게 하여 작업자가 판단을 정확히 할 수 있게 되어 안정을 기할 수 있게 되는 것이며, 밸브 내부의 협소한 공간에서도 시트전체를 촬영할 수 있도록 하여 한번에 밸브의 상태를 체크할 수 있도록 하여 작업성을 향상시킬 수 있게 되는 것이다.











As described above, according to the present invention, the photographs are taken at the same angle and position so that the size of the photograph is always the same, so that the operator can make an accurate judgment, thereby ensuring stability. By taking a picture, you can check the status of the valve at a time to improve workability.
