Description

유류탱크의 수직천공 누유감지장치 및 그 설치방법 {Oil leak detector of oil storage tank and method of establishing thereof}Oil leak detector of oil storage tank and method of establishing

본 발명은 유류탱크의 수직천공 누유감지장치 및 그 설치방법에 관한 것으로, 더욱 구체적으로는 지중으로 유류탱크가 매설된 상태에서 유류탱크의 주변에 수직으로 천공한 천공부에 누유감지부재를 설치하여 지층으로 유류가 누설되는 것을 신속하게 감지할 수 있도록 한 유류탱크의 수직천공 누유감지장치 및 그 설치방법에 관한 것이다.The present invention relates to a vertical perforated oil leakage detecting device and an installation method of the oil tank, and more specifically, to install a leakage oil detecting member in the perforated vertically periphery of the oil tank in the state in which the oil tank is buried underground The present invention relates to a vertical perforated oil leakage detection device and an installation method of the oil tank that can quickly detect the leakage of oil into the strata.

일반적으로 유류저장고, 주유소 등에서 유류를 저장하기 위해 사용하는 유류탱크는 부피가 매우 크므로 그만큼 설치면적이 넓어지고 지상설치시 외부노출로 인해 안전상의 문제점이 뒤따르게 된다. 따라서 대부분 유류탱크를 지하에 매설하여 설치면적과 안전상의 문제점을 해결하게 된다.In general, the oil tank used to store the oil in the oil reservoir, gas station, etc. is very large in volume, so the installation area is widened, and safety problems are caused by external exposure during the ground installation. Therefore, most oil tanks are buried underground to solve the problem of installation area and safety.

그러나 유류탱크가 지하에 매설됨으로써 탱크에 균열이나 파손이 발생되더라 도 육안으로 확인할 수 없는 것이었다. 이로 인해 야기되는 누유량은 엄청난 것이었고, 특히 누유되는 유류는 그대로 땅속으로 스며들어 토양과 지하수를 오염시키는 환경훼손의 심각한 문제점이 있었다.However, even when oil tanks were buried underground, even if cracks or breakage occurred in the tanks, they could not be visually confirmed. The amount of oil leakage caused by this was enormous, and there was a serious problem of environmental damage that oil leaked into the ground and contaminated soil and groundwater.

이를 감안하여 종래에도 지하에 매설되는 유류탱크의 하부에 수평으로 누유감지부재를 설치한 것이 있었으나, 유류탱크에서 누유가 발생하여 플룸(plume)의 형식으로 확산이 되면 오염지층이 누유감지부재의 인입위치와 다를 시 누유를 감지하지 못하는 상황이 발생하게 되는 등 감지효율성이 떨어지는 단점이 있다.In view of this, in the past, the oil leakage sensing member was horizontally installed in the lower part of the oil tank buried underground, but when oil leakage occurs in the oil tank and spreads in the form of plume, the contaminated layer enters the oil leakage sensing member. When the position is different from the above, there is a disadvantage in that the detection efficiency is inferior, such as a situation in which leakage is not detected.

또한, 종래에는 지하에 유류탱크에 매설된 상태에서는 하부에 누유감지부재를 설치할 수 없었고, 유류탱크를 지하에 매설하기 전에 누유감지부재를 설치해야 할 뿐만 아니라 누유감지부재의 교체 및 수리 등을 하기 위해서는 유류탱크를 분리해야 하므로 누유감지부재의 지속적인 관리에 어려움이 있다.In addition, in the prior art, the oil leakage detecting member could not be installed at the lower part when the oil tank was buried underground, and before the oil tank was buried underground, the oil leakage detecting member had to be installed, and the oil leakage detecting member was replaced and repaired. In order to separate the oil tank, it is difficult to continuously manage the leak detection member.

또, 종래에는 유류탱크 하부에 설치된 수평으로 설치된 누유감지부재가 지하수 등의 영향에 의해 지반이 침하하는 경우에 설치위치가 변경되더라도 이를 쉽게 확인할 수 없었기 때문에 누유감지부재가 제 기능을 발휘하는지 알 수 없었고, 감지부재의 증설 등에 어려움이 있다.In addition, in the related art, the horizontal oil leakage detecting member installed in the lower portion of the oil tank is not easily confirmed even if the installation position is changed when the ground subsides due to the influence of groundwater. No, there is a difficulty in adding the sensing member.

본 발명은 이러한 문제점을 해결하기 위하여 안출한 것으로, 지중으로 유류탱크가 매설된 상태에서 유류탱크의 주변에 등간격으로 수직으로 형성한 천공부에 다수의 통공이 형성된 유공관을 설치하고 상기 유공관 내에 감지선과 신호선으로 구비된 누유감지부재를 내장한 다음 누유감지부재의 상단은 감지선과 신호선이 인출되어 지상에 설치되는 제어부로 인가되게 한 구성으로 유류탱크에서 플룸(plume)의 형식으로 누유가 발생하여 확산이 되는 것을 신속하고 정확하게 감지할 수 있고 누유감지부재의 교체 등이 용이하고 설치가 용이하도록 한 것이다.The present invention has been made to solve this problem, and installed in the perforated portion formed vertically at equal intervals vertically at the periphery of the oil tank in the state in which the oil tank is buried underground and installed in the perforated pipes The oil leakage detecting member provided with wires and signal lines is built in, and the upper end of the oil leakage detecting member is configured so that the detection lines and signal lines are drawn out and applied to the control unit installed on the ground, and oil leakage occurs in the form of plume in the oil tank. This will be able to quickly and accurately detect and to facilitate the replacement of the leak detection member and easy installation.

또, 상기 천공부와 유공관 사이의 공간부에는 모래를 채운 다공층을 형성하여 다공층에 의해 누설되는 유류가 신속하게 유공관 내에 침투하여 누유감지부재에 전달되도록 함으로서 감지효율성을 높일 수 있도록 함에 있다.In addition, by forming a porous layer filled with sand in the space portion between the perforated portion and the perforated tube, the oil leaked by the perforated layer may quickly penetrate into the perforated tube and be delivered to the leaked oil detecting member to increase the sensing efficiency.

본 발명은 유류탱크의 주변에 등간격으로 수직으로 형성한 천공부에 유공관이 직립되게 설치되되 주벽 둘레에 다수의 통공이 형성되어 중공부와 관통되게 한 유공관과, 상기 유공관 내에 길이방향으로 설치되어 용제(유류)와 화학적으로 반응하여 부풀어 오르도록 한 튜브의 내부에 두 가닥의 신호선과 두 가닥의 감지선이 구비되고 튜브 외부는 메쉬형 커버로 감싸진 형태로 구비된 누유감지장치와, 상기 누유감지부재의 신호선과 감지선이 인출되어 제어부로 인가되게 한 구성으로 누유를 감지할 수 있도록 한 유류탱크의 수직천공 누유감지장치 및 그 설치방법을 특징으로 한다.The present invention is installed in the perforated portion formed vertically at equal intervals in the periphery of the oil tank upright, but a plurality of through-holes are formed around the main wall through the hollow portion and the perforated pipe, and installed in the longitudinal direction in the perforated pipe The oil leakage detection device is provided with two strands of signal lines and two strands of sensing lines inside the tube to swell chemically with a solvent (oil), and the outside of the tube is covered with a mesh cover. It is characterized by a vertical perforated oil leakage detection device and an installation method of the oil tank to detect the oil leakage in the configuration that the signal line and the detection line of the sensing member is drawn out and applied to the controller.

본 발명은 지중으로 유류탱크가 매설된 상태에서 유류탱크의 주변에 등간격으로 수직으로 천공하여 누유감지부재를 포함하는 누유감지장치를 간편하게 설치할 수 있고, 이러한 수직으로 설치된 누유감지장치에 의해 플룸(plume)의 형식으로 확산되는 오염지층의 누유상태를 정확하고 효과적으로 감지할 수 있게 되어 감지효율성을 높일 수 있게 되며, 누유감지부재의 교체 및 수리를 용이하므로 안정적이고 지속적인 관리가 가능하며, 천공부와 유공관 사이에 형성되는 다공층에 의해 누설되는 유류가 쉽게 누유감지부재에 침투하여 신속한 감지를 할 수 있는 효과가 있다.The present invention can easily install an oil leak detecting device including an oil leak detecting member by perforating vertically at equal intervals around the oil tank in a state where the oil tank is buried underground, and using a plume oil leak detecting device installed vertically ( It is possible to accurately and effectively detect the leakage state of the polluted layer spread in the form of plume), which improves the efficiency of detection.

상기와 같은 본 발명의 유류탱크의 누유감지장치는 다음과 같은 과정으로 설치된다.Oil leakage detection device of the oil tank of the present invention as described above is installed in the following process.

지중에 매설된 유류탱크(10)의 주변에서 지면에 등간격으로 수직으로 천공하여서 된 천공부(20) 형성단계와, 상기 천공부(20)에 다수의 통공(36)이 형성된 유공관(30)을 직립설치하는 단계와, 상기 천공부(20)와 유공관(30) 사이의 형성되도록 한 간극부(22)에 모래를 채워 다공층(24)을 형성하는 단계와, 상기 유공관(30) 내부에 용제(유류)와 화학적으로 반응하여 부풀어 오르도록 한 튜브(46)의 내부에 두가닥의 신호선(41)과 두가닥의 감지선(42)이 구비되고 튜브(46) 외부는 메쉬형 커버(48)로 감싸진 형태로 구비된 누유감지부재(40)를 설치하는 단계와, 상기 누유감지부재(40)의 상단에 신호선(41)과 감지선(42)이 인출되어 지상에 돌출되게 설치되는 제어부(50)로 인가되게 하는 단계를 포함하여서 된 것이다.A perforated part 20 is formed by vertically perforating the ground at equal intervals in the periphery of the oil tank 10 embedded in the ground, and the perforated part 30 having a plurality of through holes 36 formed in the perforated part 20. The step of installing the upright, and filling the sand in the gap portion 22 to be formed between the perforated portion 20 and the hole tube 30 to form a porous layer 24, and in the hole tube 30 Two strands of signal lines 41 and two strands of sensing lines 42 are provided inside the tube 46 which is chemically reacted with a solvent (oil) to inflate, and the outside of the tube 46 has a mesh cover 48.

And 50 to be applied.

상기와 같이 설치되는 본 발명의 누유감지장치는 지중에 유류탱크(10)가 매설된 상태에서 유류탱크(10)의 주변에 수직으로 천공한 천공부(20)에 간편하고 신속하게 설치하게 되는바, 이는 유류탱크(10)에서 누유가 발생하여 플룸(plume)의 형식으로 확산이 되면 유류탱크(10)의 주변에 등간격으로 수직으로 천공된 어느 하나의 천공부(20)에 도달하게 되면서 천공부(20)에 설치된 유공관(30)을 거쳐 누유감지부재(40)에 침투하여 용제(유류)를 감지하는 감지선(42)에 의해 누유감지를 하여 이를 제어부(50)에 인가하는 수단으로 누유감지를 하게 된다.The oil leakage detecting device of the present invention installed as described above is easily and quickly installed in the perforated part 20 drilled vertically around the oil tank 10 in the state where the oil tank 10 is buried in the ground. When the oil leaks from the oil tank 10 and diffuses in the form of plume, the oil reaches the one perforated part 20 vertically perforated at equal intervals around the oil tank 10. Leak oil is detected by means of a sensing line 42 that penetrates through the oil pipe 30 installed in the study 20 and detects a solvent (oil) and applies it to the controller 50. Will be detected.

이때 누유감지부재(40)의 다공성 폴리머 튜브(46)는 물은 통과하지 못하도록 하면서 용제(유류)에 의해 부풀어오르는 화학반응을 일으키게 되면 메쉬형 커버(48)에 의해 튜브(46)가 내측으로 부풀어오르면서 튜브(46) 내에 있는 두가닥의 감지선(42)이 튜브(46)와 접촉되어 쇼트(short)가 발생하게 되는바, 이러한 쇼트 발생으로 인하여 평시와 다른 전류 루프를 변경시키면서 생성되는 저항값은 신호선(41)에 의해 제어부(50)에 인가하여 제어부(50)에서 거리 표시 및 경고음과 같은 경보신호에 의해 누유상태를 지속적으로 감지하게 된다.At this time, when the porous polymer tube 46 of the oil leakage detecting member 40 causes a chemical reaction that is swelled by a solvent (oil) while preventing water from passing through, the tube 46 is inflated by the mesh cover 48 to the inside. As the two strands of the sensing line 42 in the tube 46 are in contact with the tube 46, a short is generated. As a result of the short, a resistance generated by changing a current loop different from the normal time is generated. The value is applied to the controller 50 by the signal line 41 so that the controller 50 continuously detects a leakage state by an alarm signal such as a distance display and a warning sound.

즉, 본 발명은 누유발생이 되지 않은 평상시에는 도 8의 (가)에서 보는 바와 같이 튜브(46) 내에 누유감지부재(40)에 두가닥의 감지선(42)이 튜브(46)와 이격된 상태로 놓여 있고, 누유가 발생하여 튜브(46)에 용제(유류)가 접촉하게 되면 도 8 의 (나)에서와 같이 튜브(46)가 내측으로 부풀어 오르게 되고, 이와 같이 튜브(46)가 점차적으로 부풀어오르면서 두가닥의 감지선(42)과 접촉하게 되면 도 8의 (다)와 같이 쇼트(short)가 발생하는 수단에 의해 누유감지신호를 제어부(50)로 인가하게 되는 것이다.That is, according to the present invention, as shown in (a) of FIG. 8, when the leakage oil is not normally generated, two detection lines 42 are separated from the tube 46 by the leakage detection member 40 in the tube 46. When it is in a state where leakage occurs and the solvent (oil) comes into contact with the tube 46, the tube 46 swells inward as shown in (b) of FIG. 8, and the tube 46 is gradually When inflated to contact the two sensing lines 42, the leak detection signal is applied to the controller 50 by means of generating a short as shown in FIG.
