주유소용 유량측정장치{The flow meter for a gasoline station}Flow meter for gas station {The flow meter for a gasoline station}

본 발명은 주유소용 유량측정장치에 관한 것으로서, 더욱상세하게는 레이저 거리측정기를 이용하여 유류탱크 내부의 유량을 측정함으로써, 줄자를 이용하여 눈금을 확인하거나 또는 도르래의 회전수를 감지하여 유량을 측정하는 장치들에 비하여 구조가 간단하고 저렴한 가격으로 제작할 수 있는 주유소용 유량측정장치에 관한 것이다.The present invention relates to a flow rate measuring device for a gas station, more specifically, by measuring the flow rate inside the oil tank using a laser range finder, by using a tape measure to check the scale or to detect the rotational speed of the pulley to measure the flow rate The present invention relates to a flow measuring device for a gas station, which is simple in structure and can be manufactured at a low price as compared to the devices.

일반적으로 주유소의 유류탱크에 저장된 휘발유 또는 경유의 량을 정확하게 측정하여 재고관리 및 일일 판매량을 확인하고 있는데, 상기 유류탱크가 지하에 매설된 관계로 인하여 직접 확인하기가 쉽지 않기 때문에 대부분 유류탱크 내부에 부구를 설치하고 이 부구의 수두차를 측정하여 유량을 확인하였다.In general, the amount of gasoline or diesel stored in the oil tank of the gas station is accurately measured to check inventory management and daily sales volume. Since the oil tank is buried underground, it is not easy to check it directly. A float was installed and the head difference was measured to check the flow rate.

종래에는 국내 공개특허 제1993-0001723호에 포텐쇼미터를 이용하여 유량을 측정하거나 또는 국내 공개특허 제2009-0103215호에 개시된 바와같이 엔코더를 이용하여 유량을 측정하였다.In the related art, a flow rate was measured using a potentiometer in Korean Patent Publication No. 1993-0001723 or an encoder as disclosed in Korean Patent Publication No. 2009-0103215.

이들 종래의 방식들은 상기 부구와 로프로 연결된 도르래의 회전수를 감지하여 이를 전기적 신호로 변환한뒤 유량을 환산하는 방식이었다. 그러나 로프가 휘발유나 경유에 잠기기 때문에 도르래에 감기는 로프가 헛돌게 되면 정확한 회전수를 감지할 수 없으므로 유량 환산에 오차가 발생되는 문제가 있었다.These conventional methods were to convert the flow rate after converting the number of revolutions of the pulley connected to the float and the rope to an electrical signal. However, because the rope is immersed in gasoline or diesel, the rope wound on the pulley can not detect the exact number of revolutions because the rope pulled out, there was a problem in the conversion of the flow rate.

또한 국내 특허 제915382호에는 눈금자를 이용하여 유량을 측정하는 장치가 제안된 바 있다. 이는 상기 눈금자의 양단에 부구와 무게추를 연결하고 상부는 롤러에 걸어둔 구성으로써, 상부 롤러가 있는 곳에 투시창을 마련하여 눈금을 육안으로 확인하도록 구성된 것이다. 그러나 유량을 직접 확인하고 환산해야 되므로 번거로운 단점이 있으며, 무게추와 줄자 및 롤러와 부구 등 다수의 부품이 필요하므로 구성이 복잡한 등의 단점이 있었다.In addition, Korean Patent No. 9938 has proposed a device for measuring the flow rate using a ruler. It is configured to connect the ball and the weight on both ends of the ruler, and the upper part is hanged on the roller, to provide a viewing window where the upper roller is located to visually check the scale. However, there is a disadvantage in that it is cumbersome because the flow rate must be checked and converted directly, and a large number of components such as weights, tape measure, rollers, and balls are required.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 레이저 거리측정기를 이용하여 유류탱크 내부의 유량을 측정함으로써, 줄자를 이용하여 눈금을 확인하거나 또는 도르래의 회전수를 감지하여 유량을 측정하는 장치들에 비하여 구조가 간단하고 또한 원격지 사무실에서 유량을 실시간으로 확인할 수 있으므로 재고 및 판매관리가 편리한 주유소용 유량측정장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to measure the flow rate inside the oil tank using a laser range finder, to check the scale using a tape measure or to detect the rotational speed of the pulley Compared to the measuring devices, the structure is simple and the remote office can check the flow rate in real time, thereby providing a flow rate measuring device for a gas station that is convenient for inventory and sales management.

이를 위하여 본 발명은 유류탱크 상부의 검사구에 보호캡이 구비되고, 상기 보호캡의 상단에는 레이저 거리측정기가 구비되며, 상기 보호캡의 내부에는 유류에 잠기는 승강안내축이 수직으로 구비되고, 상기 승강안내축에는 상기 레이저 거리측정기 쪽으로 승강되는 부구가 구비되어 상기 레이저 거리측정기의 광발생부에서 발사된 레이저가 상기 부구에서 반사된 뒤 상기 레어저 거리측정기의 광검출부에 도달된 시간을 거리로 환산하여 유량이 측정되도록 한 특징이 있다.To this end, the present invention is provided with a protective cap in the inspection port of the upper portion of the oil tank, the upper end of the protective cap is provided with a laser range finder, the lifting guide shaft to be immersed in the oil is provided vertically inside the protective cap, A lifting guide shaft is provided with a float that is lifted toward the laser range finder so that the laser light emitted from the light generating portion of the laser range finder is reflected from the float and converted to the distance of reaching the light detector of the laser range finder as a distance. It is characterized by the flow rate to be measured.

본 발명에 따르면 레이저 거리측정기를 이용하여 유량을 측정하기 때문에 줄자를 이용하여 눈금을 확인하는 방식에 비하여 편리하고 유량을 정확하게 측정할 수 있는 이점이 있다. 또한 엔코더나 포텐쇼미터를 이용하여 도르래의 회전수를 전기적 신호로 변환한 뒤 이를 이용하여 유량을 환산하는 방식에 비하여 구성이 간단하다.According to the present invention, since the flow rate is measured using a laser range finder, there is an advantage in that the flow rate is more convenient and accurate than the method of checking the scale using a tape measure. In addition, the configuration is simpler than using a encoder or a potentiometer to convert the rotational speed of the pulley into an electrical signal and convert the flow rate using the same.

즉 엔코더나 포텐쇼미터의 경우 부구와 무게추 및 이들을 연결하는 로프와 도르래가 있어야 하나 본 발명의 경우 레이저 거리측정기 및 부구만 있으면 유량을 정확하게 측정할 수 있으므로 구성이 간단하다. 또한 엔코더나 포텐쇼미터의 경우 로프가 유류에 잠기기 때문에 도르래에 걸려 헛돌수 있으므로 회전수를 정확하게 감지할 수 없는 구조적인 단점이 있으나, 본 발명의 레이저 거리측정기의 경우 부구의 높낮이에 따른 레이저의 반사거리만 정확하게 측정하면 되므로 유량을 보다 정확하게 측정할 수 있으며 원거리의 사무실에서 유류탱크 내부의 유량을 실시간으로 정확하게 측정하므로 재고 및 판매관리가 편리해지는 이점이 있다.That is, in the case of an encoder or a potentiometer, a weight and weight and a rope and a pulley connecting them should be provided. However, in the present invention, a laser range finder and a float can be used to accurately measure the flow rate, so the configuration is simple. In addition, in the case of encoders or potentiometers, ropes are immersed in oil, so they may be caught in pulleys, and thus there is a structural disadvantage in that the rotational speed cannot be accurately detected. Because accurate measurement is possible, the flow rate can be measured more accurately, and the flow rate inside the oil tank is accurately measured in real time in the remote office, which has the advantage of convenient inventory and sales management.
