Description

광섬유를 이용한 비만관 수위 측정 장치{level meter device with optical fiber}Obesity tube level measurement device using optical fiber

본 발명은 어두운 맨홀 내에 설치된 비만관의 수위를 측정하는 장치에 관한 것으로 더욱 상세하게는 광섬유를 이용하여 비만관의 수위를 측정하는 장치에 관한 것이다.The present invention relates to an apparatus for measuring the level of obesity tubes installed in a dark manhole, and more particularly, to an apparatus for measuring the level of obesity tubes using an optical fiber.

유체가 관을 완전히 채우지 않은 상태의 비만관에서의 유량을 측정하는 비만관 유량계로는 다양한 형태의 것이 있으나, 크게 초음파 수위계와 압력 수위계로 대별될 수 있다.There are various types of obesity tube flowmeters for measuring the flow rate in the obesity tube in which the fluid does not completely fill the tube, but it can be roughly classified into an ultrasonic level gauge and a pressure level gauge.

초음파 수위계는 발진된 초음파가 수면과 바닥을 통해 반사되어 되돌아오는 시간차에 따른 환산값을 이용하여 수위를 계측하고, 압력 수위계는 수위에 따라 가해지는 수압차를 계산하여 수위를 계측하는 유량계이다.The ultrasonic level gauge measures the water level using the converted value according to the time difference when the oscillated ultrasonic wave is reflected through the water surface and the bottom, and the pressure level meter measures the water level by calculating the pressure difference applied according to the water level.

초기에는 압력 수위계만을 사용하였으나, 압력 수위계의 경우 6 시 방향에 압력 센서가 설치되기 때문에 부득이하게 함유된 침전물이나 고형물들에 의해 압력 전송관이 막히게 되면 압력 센서가 측정한 정보를 송신할 수 없게 되는 문제가 발생한 바, 이러한 단점을 극복하기 위하여 초음파 수위계도 비만관 유량계에 사용하게 되었다.Initially, only the pressure level gauge was used. However, in the case of the pressure level gauge, the pressure sensor is installed at the 6 o'clock position, so if the pressure transmission pipe is blocked by inadvertently contained sediment or solids, the pressure sensor cannot transmit the information. In order to overcome this drawback, an ultrasonic water level meter has also been used in an obesity tube flow meter.

도 1 은 종래의 초음파 압력 복합 수위계측식 비만관 유량계를 나타낸 도면이다. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing a conventional ultrasonic pressure complex level gauge type obesity flowmeter.

이러한 유량측정장치에는 배관(100)의 하단에 유속을 측정하여 유량을 산출하는 유량센서(200)가 설치되고, 또한, 수위를 측정하기 위해 배관(100)의 하단 일측에 압력센서(300)가 설치되고, 초음파 센서 (400) 가 배관 (100) 의 상단에 설치되어 수위를 측정하게 된다.The flow rate measuring device is provided with a flow rate sensor 200 for calculating the flow rate by measuring the flow rate at the bottom of the pipe 100, and, in order to measure the water level, the pressure sensor 300 is provided on one side of the bottom of the pipe 100 The ultrasonic sensor 400 is installed on the upper end of the pipe 100 to measure the water level.

그러나 이러한 종래의 비만관 수위표시장치는 센서를 통해 수위를 표시하게 되는 바, 배관 내의 수위를 눈으로 볼 수 없고, 센서가 고장난 경우에는 수위 측정이 불가능하다는 단점이 있다. 또한, 구조가 복잡하고 유량계가 맨홀 내에 설치되어 있기 때문에 조명수단이 별도로 필요하다는 단점이 있다.
However, such a conventional obesity tube level display device displays the water level through the sensor, there is a disadvantage that the water level in the pipe can not be seen visually, the water level measurement is impossible when the sensor is broken. In addition, since the structure is complicated and the flow meter is installed in the manhole, there is a disadvantage that the lighting means is required separately.

광원(54)으로의 전원공급은 접촉단자 또는 전원선(58)과 같은 일반적인 방법으로 가능하다.Power supply to the light source 54 is possible in a general manner such as contact terminal or power line 58.

슬레이트(56)는 양 단부가 이동가이드 홈(59)에 삽입되는 ㄷ 자 형태로 제조되며, 슬레이트(56)의 중앙부에 설치된 광원(54)으로의 전원 공급은 입광부 내부에 삽입되는 배터리와 연결된 전원선(58)을 광원(54)에 연결시킴으로써 달성될 수 있다.Slate 56 is manufactured in the form of the letter c is inserted into the movement guide groove 59 at both ends, the power supply to the light source 54 installed in the center portion of the slate 56 is connected to the battery inserted into the light incident portion This can be accomplished by connecting the power supply line 58 to the light source 54.

입광부(50) 측면에 전원선(58)을 이동가이드 홈(59)을 따라 부착하고 슬레이트(56)에 전원선(58)과 전기적으로 접촉되는 전원단자를 구비하여 슬레이트(56)를 이동할 때 슬레이트(56)의 전원단자가 입광부(50)의 전원선(58)과 접촉되어 전원이 공급될 수 있도록 한다.
When the power line 58 is attached to the side of the light incident part 50 along the movement guide groove 59 and the slate 56 is provided with a power terminal that is in electrical contact with the power line 58. The power terminal of the slate 56 is in contact with the power line 58 of the light incident portion 50 so that power can be supplied.

이하, 상기 구성으로 인한 본 발명의 작용에 대하여 설명한다.Hereinafter, the operation of the present invention due to the above configuration will be described.

작업자에게 보이는 출광부(40) 측의 광섬유(42)의 발광이 부유체(17)의 수위를 경계로 달라지는 바, 광섬유(42)의 발광이 보이는 부분과 보이지 않는 부분의 경계에 해당하는 슬레이트(56) 위치의 눈금(53)을 읽어 하수의 수위를 알 수 있다.Since the light emission of the optical fiber 42 on the light exiting part 40 side seen by the worker varies with the boundary of the water level of the floating body 17, a slate corresponding to the boundary between the visible and invisible portions of the optical fiber 42 ( 56) The level of the sewage can be known by reading the scale 53 of the position.

작업자는 입광부(50) 측의 슬레이트(56)를 좌우로 이동시키면서 투명관(16)에 비치는 빛, 즉 출광부(40) 측에서 발광되는 빛의 발광상태를 본다.The worker sees the light emitting state of the light reflected on the transparent tube 16, that is, the light emitted from the light exiting part 40 side while moving the slate 56 on the light incident part 50 side.

만약, 관(2)의 수위가 절반 정도 차 있다고 가정하였을 때, 슬레이트(56)가 입광부(50)의 중간 정도 위치에 왔을 때, 즉 슬레이트(56)의 광원(54)의 빛이 입광부(50)의 중간에 설치된 광섬유(42)에 입사될 때, 출광부(40)에서 발광되는 빛은 부유체(17)에 가려 작업자는 빛을 확인할 수 없다.If it is assumed that the water level of the tube 2 is about half full, when the slate 56 is in the middle position of the light incident portion 50, that is, the light of the light source 54 of the slate 56 is incident on the light incident portion. When incident on the optical fiber 42 installed in the middle of the 50, the light emitted from the light exit portion 40 is covered by the floating body 17, the operator can not confirm the light.

즉, 부유체(17)가 위치한 수평선상의 광섬유(42)에서 발광되는 빛은 부유체(17)에 가려서 작업자의 눈에 보이지 않지만, 상기 수평선 위에 위치한 광섬유(42)에서 발광되는 빛은 작업자에게 보인다.That is, the light emitted from the optical fiber 42 on the horizontal line on which the floating body 17 is located is not visible to the operator because it is covered by the floating body 17, but the light emitted from the optical fiber 42 located on the horizontal line is visible to the worker. .

따라서, 슬레이트(56)를 움직일 때 투명관(16)에 비치는 불빛이 보이는 위치와 안보이는 위치의 경계가 바로 관 내의 유체 수위가 된다.
Therefore, the boundary between the position where the light reflected on the transparent tube 16 is visible and the invisible position when the slate 56 is moved is the fluid level in the tube.

그러므로, 지금까지 전술한 예는 모든 면에서 예시적인 것으로서, 본 발명을 한정하기 위한 것이 아니며, 특허청구범위의 의미 및 범위 그리고 균등한 개념으로부터 도출되는 모든 변경 또는 변형된 형태가 본 발명의 범위에 포함된다.Thus, the foregoing examples are to be considered in all respects only as illustrative and not restrictive of the invention, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts are within the scope of the invention.
