본 고안은 파이프 관내를 직시 촬영함은 물론 관내측벽을 원추형으로 돌아가면서 특시 촬영이 가능하도록 하여 관내측벽 및 분기관의 상태를 명확히 조사 확인할 수 있게한 파이프내에 조사용 TV카메라 헤드의 측시촬영장치에 관한 것이다.The present invention not only photographs the inside of the pipe directly, but also enables the special shooting by rotating the inside wall of the pipe in a conical shape so that the state of the inside wall and the branch pipe can be clearly investigated and checked. It is about.

종래에는 파이프내에 스케일이 끼이거나 이임부가 어긋나거나 또는 부식공 등이 생기는 것을 확인하기 위하여 관내에 TV카메라 헤드를 진행시키어 그 전방을 직시 촬영하여 조사하고 있으나, 직시 촬영시에는 통상 TV카메라 헤드의 촛점거리가 50-100㎜이기 때문에 피사체의 모습이 파이프관내 50-100㎜사이의 전체 모습이 나타나므로 관내의 전체적 상태를 알 수 있으나, 관내측벽의 일부를 촬영하거나 또는 기존 파이프에 연결된 분기관의 이옴부 및 그 분기관 내부를 전현 촬영할 수 없는 실정이다.Conventionally, in order to check whether the scale is pinched in the pipe, the seams are shifted, or the corrosion hole is made, the TV camera head is advanced in the tube and the front of the tube is photographed and examined. Because the distance is 50-100mm, the whole body of the subject appears between 50-100mm in the pipe, so the overall condition of the pipe can be seen.However, the part of the inner wall of the pipe can be taken or the branch of the branch pipe connected to the existing pipe can be seen. The omnibus and its branch can not be filmed inside.

본 고안은 이러한 문제점을 해결하기 위하여 안출된 것으로 몸체내에 TV카메라 헤드부를 모우터에 의해 좌우를 회전되게 하고 몸체의 선단부에는 TV카메라 헤드부와 연통되는 커버를 돌설시키어 그 내에 위치한 TV카메라 헤드의 렌즈부 전방에 솔레노이드에 의해 반사경이 각도 조정되도록 하므로서 TV카메라 헤드부를 회전시키어 촬영위치에 설정시킨 후 반사경을 통하여 관내의 측벽이나 분기관의 연결부 및 그 내부를 명확히 조사할 수 있게 하는데 그 목적이 있다.The present invention was devised to solve this problem, and the lens of the TV camera head located therein is rotated left and right by the motor and the cover is in communication with the TV camera head part at the tip of the body. The angle of the reflector is adjusted by the solenoid in front of the part so that the TV camera head can be rotated and set at the photographing position, and then the reflector can clearly examine the connection part and the inside of the side wall or branch pipe in the tube.

이하 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter will be described in detail based on the accompanying drawings.

내부 중앙에 격벽(2)이 형성된 관형의 몸체(1)내의 전방에 TV카메라 헤드부(3)가 내삽되어 TV카메라 헤브부(3)의 후면 중앙에 마련된 중심축(5)이 격벽(2)의 중앙에 축설되고 이 중심축(5)에는 대기어(6)가 고정되어 그 양측에 모우터(9)에 의해 전동되는 소기어(7) 및 로터리 인코더(Rotary Encorder)(10)의 소기어(8)가 각각 치합하여 연동되며 TV카메라 헤드부(3)의 둘레에는 TV카메라 헤드부(3)의 외면에 접하도록 여러개의 로울러(11)(11')가 몸체(1)내의 고정 설치된다.The TV camera head portion 3 is inserted in the front of the tubular body 1 in which the partition wall 2 is formed in the inner center, so that the central axis 5 provided at the rear center of the TV camera head part 3 is the partition wall 2. Small gears 7 and rotary encoders 10, which are arranged in the center of the main shaft 5 and which are equipped with a standby gear 6 fixed to the central shaft 5 and driven by a motor 9 on both sides thereof. (8) is interlocked with each other, and a plurality of rollers (11, 11 ') are fixedly installed in the body (1) so as to contact the outer surface of the TV camera head (3) around the TV camera head (3). .

그리고 몸체(1)의 선단부에는 커버(12)가 TV카메라 헤드부(3)에 고정되면서 몸체(1)에 유설되어 TV카메라 헤드부(3)와 연동되어진다.The cover 12 is fixed to the TV camera head 3 at the distal end of the body 1, and remains on the body 1 to be interlocked with the TV camera head 3.

상기 커버(12)는 상부가 절곡되고 그 후방에 돌출부(12')가 형성되어져 커버(12)의 전면 및 상면에 투시부(13)(13')가 구비되고 그 투시전방을 밝게 조명할수 있도록 전면 투시부(13)의 둘레에는 여러개의 헬로겐램프(14)가 설치되며 또한 돌출부(12')상에도 헬로겐램프(14')가 설치되어진다.The cover 12 is bent at the top and a protrusion 12 'is formed at the rear thereof, so that the projections 13 and 13' are provided on the front and the upper surface of the cover 12 so that the front and the front of the cover are brightly illuminated. A plurality of hellogen lamps 14 are installed around the front perspective part 13, and a hellogen lamp 14 ′ is also provided on the protrusion 12 ′.

또 커버(12)내의 렌즈부(4)의 전방에는 상면에 위치한 투시부(13')를 비출수 있도록 반사경(15)이 솔레노이드(16)의 작동에 의해 적정각도로 위치되게 유설되어진다.In addition, in front of the lens portion 4 in the cover 12, the reflector 15 is positioned to be positioned at an appropriate angle by the operation of the solenoid 16 so as to project the see-through portion 13 'positioned on the upper surface.

아울러 커버(12)의 외부로 노출되어 결합되는 부품들을 외부의 물이 유입되지 않도록 밀폐되어 있다.In addition, the parts that are exposed and coupled to the outside of the cover 12 are sealed to prevent external water from entering.

미 설명부호 17은 콘넥타, 18은 밀폐용 베어링, 19는 파이프, 20은 분기관, 21은 케이블이다.Reference numeral 17 is a connector, 18 is a sealing bearing, 19 is a pipe, 20 is a branch pipe, 21 is a cable.

이와같이 구성된 본 고안은 몸체(1)에 자주차나 미끄럼쇠(도면에 표시되지 않았음)등을 부착시키어 파이프(19)내에서 진행시키게 되는데 제4도의 (a)에서와 같이 파이프(19)내를 직시 촬영시에는 솔레노이드(15)를 작동시키어 렌즈부(4)의 전방에 위치한 반사경(15)이 하방으로 내려가게 되면 렌즈부(4)가 그 전방의 투시부(13)를 통해 직사되면서 파이프(19)내의 전방부가 촬영되어 이를 TV를 통해 관내의 전체적인 상태를 조사하게되고 관내의 측벽을 보고자 할때에는 다시 솔레노이드(16)를 다시 작동시키어 커버(12)의 상면에 위치한 투시부(13')로 부터 들어오는 피사체가 렌즈부(4)에 들어오도록 반사경(15)이 위치시키고 동시에 모우터(9)를 구동시키면 TV카메라 헤드부(3)가 회전되면서 관내측벽의 피사체가 반사경(15)을 통해 촬영되어 관내측벽 둘레의 상태를 면밀히 조사할 수 있게되고 TV카메라 헤드부(3)의 좌우 회전범위는 대기어(6)에 의해 치합 연동되어 작동하는 로터리 인코더(10)가 입력되어 있는 지정 회전범위 만큼 모우터(9)를 콘트롤시키어 준다.The present invention configured as described above proceeds in the pipe 19 by attaching a car or a slip (not shown in the drawing) to the body 1 and proceeds in the pipe 19, as shown in (a) of FIG. In direct view, when the solenoid 15 is operated so that the reflector 15 located in front of the lens unit 4 descends downward, the lens unit 4 is directly struck through the front view unit 13 in front of the pipe ( 19) The front part of the body is photographed to examine the overall condition of the inside of the tube through the TV. To see the side wall of the tube, the solenoid 16 is operated again to the see-through part 13 'located on the upper surface of the cover 12. When the reflector 15 is positioned so that the incoming object enters the lens unit 4 and the motor 9 is driven at the same time, the TV camera head 3 is rotated and the subject of the inner wall is photographed through the reflector 15. The state around the inner wall The left and right rotation ranges of the TV camera head 3 can be closely inspected and the motor 9 is controlled by the designated rotation range in which the rotary encoder 10 operated in engagement with the standby gear 6 is input. Let it be.

그리고 제4도의 (b)와 같이 몸체(1)가 분기관(20)에 이르게 되어 그 내부를 조사하고자 할 경우에는 그 위치에서 진행을 정지시키고 커버(12)의 상면에 위치한 투시부(13')를 분기관(20)내를 볼수 있게 모우터(9)를 정지시키게 되면 TV카메라 헤드부(3)가 투시부(13')를 통하여 반사경(15)에 비추어주는 분기관(20)의 이음부 및 분기관(20)를 촬영하여 TV에 송출하므로서 TV를 통해 그 내부 상태를 면밀히 조사할 수 있게된다.And as shown in (b) of FIG. 4, when the body 1 reaches the branch pipe 20 and wants to examine the inside thereof, the process stops at the position and the perspective part 13 'located on the upper surface of the cover 12. When the motor 9 is stopped so that the inside of the branch pipe 20 can be seen, the joint of the branch pipe 20 through which the TV camera head 3 projects the reflector 15 through the see-through part 13 'is reflected. By taking the secondary and branch pipes 20 and sending them to the TV, it is possible to closely examine the internal state through the TV.

이상과 같이 본 고안은 관(19)내벽의 측부만을 촬영하여 볼 수 있을 뿐만 아니라, 진행하다가 각 부위에 연결된 분기관(20)의 내부까지 극히 간단한 조정에 의해 촬영할 수 있어 그 시용범위를 극대화 할수 있는 우수한 고안이다.As described above, the present invention can not only photograph and view the side portion of the inner wall of the tube 19, but can also be photographed by the extremely simple adjustment of the inside of the branch pipe 20 connected to each part while maximizing its application range. That is an excellent design.
