본 고안은 저유탱크의 물검출기에 관한 것으로 특히 주유소의 지하탱크 또는 주유기 펌프내의 수분검출기에 관한 것이다.The present invention relates to a water detector of a low oil tank, and more particularly, to a water detector in an underground tank or an oil pump of a gas station.

종래 저장용 기름탱크의 저면에는 기름보다 무거운 수분이 아래로 침강하여 몰림으로서 물이 고이는 예가 있다. 뿐만 아니라 또 기름 수송 차량으로 운반하여 저유할 때 고의던 고의가 아니던 물이 밑에 있을 수가 있어서 이런 것이 회를 거듭하게 되면 지하의 저장용 기름탱크에는 기름이 물위에 떠 있어서 기름의 량을 측정하기 어려운 점이 있다. 따라서 본 고안은 저장용 기름탱크 내의 물을 검출하여 마그네트 펌프에 의해 수분을 저장탱크 내로부터 제거시켜 주고저 하는 것이 본 고안의 목적이다.At the bottom of a conventional storage oil tank, there is an example in which water that collects by moisting down and heavier than oil is collected. In addition, when the oil is transported by an oil transportation vehicle, there may be water intentionally or unintentionally underneath it, and when this is repeated, it is difficult to measure the amount of oil because the oil is floating in the underground storage oil tank. There is a point. Therefore, an object of the present invention is to detect water in an oil storage tank and to remove water from the storage tank by a magnet pump.

상기와 같은 본 고안의 목적을 달성하기 위하여 휘발유나 등유 또는 방커씨유는 전기적으로 거의 부도체이며 또 순수한 물 또한 전기적으로 부도체이나 순수물은 거의 없고 천연의 물에는 미네랄과 같은 무기물이 용융되어 있어서 전기적으로 도전성이 있는 것에 착안하여 물검출기로 플러그를 저유탱크에 설치하여 물이 있는 경우 플러그의 플러스 단자를 통해 트랜지스터의 베이스에 인가하여 출력을 증폭시켜 경보기를 울리도록 하고 또 마그네트 펌프를 동작시켜 수분을 제거토록 한 것으로 이하 본 고안은 첨부된 도면에 따라 상술하면 다음과 같다.In order to achieve the above object of the present invention, gasoline, kerosene or bunker oil are almost non-conductors electrically, and pure water is also electrically non-conductors or pure water, and natural water is dissolved in minerals such as minerals. With the water detector installed, the plug is installed in the oil storage tank. If there is water, the plug is applied to the base of the transistor through the positive terminal of the plug to amplify the output to sound an alarm and operate the magnet pump. Hereinafter, the present invention to be removed as described in detail according to the accompanying drawings as follows.

첨부된 도면은 본 고안을 설명키 위한 전기적 회로도 플러그(Pu)의 음극(-)을 저유탱크에 접지되고 양극(+)은 저항(R1)을 통해 에미터 접지된 트랜지스터(TR1)의 베이스에 연결되고 콜렉터는 저항(R2, R3)을 통해 에미터 접지된 트랜지스터(TR2, TR3)로 되는 증폭회로를 기처 릴레이(Ry) 코일에 연결되어 있다. 또 강압트랜스(T)의 2차 측에 보리저정류회로(D)를 통해 릴레이(Ry) 코일에 정류된 전류를 공급하도록 되고 릴레이(Ry)의 접점단자에는 경보기(Sp)와 마그네트(Mg)에 연결되도록 하여서 된것이다. 도면 중 부호 C는 평활용 콘덴서이다.The drawing is an electrical circuit diagram plug (Pu) cathode for explanation key for the intended attachment-Base of being ground to a low dielectric tank anode (+) is the resistance (R 1), an emitter grounded transistor (TR 1) through () The amplification circuit connected to the relay coil Ry is connected to the collector and resistors R 2 and R 3 to emitter grounded transistors TR 2 and TR 3 . Also, the rectified current is supplied to the relay coil through the barley rectifier circuit D on the secondary side of the step-down transformer T, and the alarm Sp and the magnet Mg are provided at the contact terminals of the relay Ry. It is intended to be connected to. In the figure, code | symbol C is a smoothing capacitor.

상기와 같은 구성으로 된 것이므로 플러그(Pu)를 저장탱크의(도시하지 않은) 저면에 설치하는 경우 순수 기름만이 있을 때 플러그(Pu)의 양단자 사이는 무한대의 저항이 형성됨으로서 트랜지스터(TR1)의 베이스에는 아무런 전기적 흐름도 없으므로 트랜지스터(TR1)은 아무런 동작도 없다.Since the plug Pu is installed at the bottom of the storage tank (not shown) when the pure oil is present, an infinite resistance is formed between both terminals of the plug Pu so that the transistor TR 1 is formed. Since there is no electrical flow at the base of the transistor, the transistor TR 1 has no operation.

따라서 릴레이(Ry)의 코일을 려자하지 못해 릴레이(Ry)의 단자에 연결된 경보기(Sp)와 마그네트(Mg)에도 아무런 동작이 없다.Therefore, there is no operation in the alarm Sp and the magnet Mg connected to the terminal of the relay Ry because the coil of the relay Ry cannot be tried.

그러나 저장탱크의 저면에 설치된 플러그(Pu)의 양극 사이에 도전성의 물이 검출되는 경우 양극(+)을 통해 트랜지스터(TR1)의 베이스에는 바이페스되어 포화되기 시작함으로서 트랜지스터(TR1)의 콜렉터-에미터 사이는 도통되어 트랜지스터(TR2)에 의해 증폭되고 다시 트랜지스터(TR3)의 콜렉터-에 미터가 도통되어 릴레이(Ry)가 려자되는 것이다.However, when conductive water is detected between the anodes of the plug Pu installed on the bottom of the storage tank, the base of the transistor TR 1 is bypassed and started to saturate through the anode +, thereby collecting the collector of the transistor TR 1 . The conduction between the emitters is conducted and amplified by the transistor TR 2 , and the meter conducts again to the collector of the transistor TR 3 so that the relay Ry is intended.

따라서 릴레이(Ry) 단자에 전원과 연결되도록 되는 경보기(Sp)가 울리게 됨과 동시 마그네트(Mg)가 동작되어 수분은 저장탱크 밖으로 펌핑하게 되는 것이다. 본 고안에서 강압트랜스(T)을 사용함은 유류의 취급에 있어 불꽃 방전에 의해 유류에 정화하는 것을 방지하기 위함이며 또 트랜지스터(TR1)의 베이스와 에미터 사이에 플러그(Pu)를 연결함은 저장탱크 내에서의 전기적 접신에 의한 불꽃방전을 방지하고 확실하게 검출하기 위한 것이다.Therefore, the alarm (Sp) to be connected to the power supply to the relay (Ry) is ringing and the magnet (Mg) is operated at the same time the water is pumped out of the storage tank. The use of the step-down transformer (T) in the present invention is to prevent the purification of the oil by the spark discharge in the handling of the oil and to connect the plug (Pu) between the base and the emitter of the transistor (TR 1 ) To prevent and reliably detect spark discharges caused by electrical contact in storage tanks.

상기와 같이 본 고안을 불꽃 방전을 방지하면서도 플러그에 의해 수분을 확실하게 검출하여 경보하면서 동시에 마그네트를 동작시켜 펌핑하도록 한 것이므로 실용적이며 동작이 확실한 점 등의 효과가 있는 것이다.As described above, since the present invention prevents spark discharge and reliably detects and detects moisture by a plug while operating a magnet, the pump is pumped by a practical and reliable operation.
