BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for detecting an oil leakage in a soil, and more particularly, to an apparatus for detecting a leakage of oil in a soil that can prevent pollution of the soil and groundwater by detecting oil leaked into the soil.

Oil handling facilities such as gas stations and oil reservoirs contain not only oil storage tanks but also diverse and complex facilities for oil distribution and transport, and there is always a risk of oil leakage from each facility. Leaked oil seeps into the soil and contaminates the soil.

Prolonged soil contamination due to oil spills can directly affect the underground environment and may pollute the surrounding groundwater. Therefore, the living environment around the oil handling facilities and the industrial environment such as the enrichment industry are also deteriorated. Moreover, long-term oil leakage increases the cost of recovering soil contamination if the area in which the oil-handling facility is located is to be changed to another use.

To prevent soil contamination by oil, it should be able to detect the oil that flows into the soil. The oil leak detector can be accomplished by installing a sensor in the soil layer where oil leakage is expected.

According to the prior art, there is known a method of detecting and measuring the oil accumulated in the empty space by forming a sump in the lower soil layer of the oil-leaking device such as the oil distributor or the injection device of the oil-handling facility have.

However, the above-described technology for forming a void space in the soil layer is problematic in that it is expensive and installation is complicated. That is, in order to form an empty space in the soil layer, the size of the work including excavation is increased, and in order to form an empty space in the lower portion of the existing facility, temporary transfer of the facility is also required.

On the other hand, according to Japanese Laid-Open Patent Publication No. 2011-0137162, there is disclosed a leak detection method of a leak detection system including a leak detection unit, a central processing unit, and a web server provided with an oil detection sensor including an optical fiber sensor installed in a specific place.

The oil leakage detection method may include detecting oil detected by the oil leakage detection unit through the oil detection sensor; Receiving, by the central processing unit, the detected state information of the detected oil using at least one of the Internet, the wireless communication, and the geographic information system (GIS); And the central processing unit transmitting the received detection status information of the oil to a specific web server.

The infrared sensor or the buoy type sensor used as the oil detection sensor in the above conventional art has a problem in that it is not suitable for detecting the oil leaked to the soil.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for detecting a leakage of a soil.

Another object of the present invention is to provide an apparatus for detecting a leak in a soil which can be installed simply at a relatively low cost.

It is another object of the present invention to provide an oil-based exposure sensing apparatus which can be widely installed around a oil-handling facility so as to prevent contamination of soil and groundwater in advance.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings.

1 is a schematic perspective view of an apparatus for detecting a leakage of a soil according to the present invention.

Referring to the drawings, an apparatus for detecting a leaking oil in a soil according to the present invention comprises a funnel 10 composed of a truncated conical portion 10a and a cylindrical portion 10b and buried in the ground, And a communication cable 12 extending from the resistance sensor 11. The resistance sensor 11 is inserted into the cylindrical portion 10b of the housing 10,

The funnel 10 has a truncated conic section 10a as shown in the figure. When the funnel 10 is buried in the ground, the extended upper portion of the truncated conic section 10a faces upward. The expanded upper portion of the truncated conic section 10a has a function of attracting the oil permeated into the soil into the interior of the funnel 10.

It is preferable that a plurality of grooves 10c are formed on the inner surface of the truncated conic section 10a. The plurality of grooves 10c extend from the upper portion toward the cylindrical portion 10b. The leaked oil can be collected in the cylindrical portion 10b along the plurality of grooves 10c.

A cylindrical portion 10b extends below the truncated conic section 10a. A resistance sensor 11 is inserted into the cylindrical portion 10b. It is preferable that the diameter of the cylindrical portion 10b is determined so as to be suitable for the size of the resistance sensor 11. [ A minute gap is formed between the outer surface of the resistance sensor 11 and the cylindrical portion 10b so that the fluid can flow downward.

A valve 15 may be provided under the cylindrical portion 10b. The valve 15 includes a blocking member 15a having an opening and a shutter 15b capable of opening and closing the opening. The shutter 15b can be rotatably installed by an actuator (not shown). When the valve 15 is opened, fluid introduced into the funnel 10 can be discharged naturally by gravity. When the valve 15 is closed, water or leaked oil may be present inside the funnel 10.

It is preferable that the resistance sensor 11 is installed in the cylindrical portion 10b in a state covered with, for example, the epoxy 11a. The communication cable 12 extends from the bottom of the resistance sensor 11. The resistance sensor 11 may have various configurations.

As shown in FIG. 2, the resistance sensor may include a base film 21 and a conductive strip line 22 deposited on the upper surface of the base film.

The conductive strip line 22 is formed of a polymer compound such as a porous polymer or a conductive polymer. When the oil contacts the conductive strip line, the resistance value of the conductive strip line 22 changes, so that it is possible to sense that the oil has leaked. The base film 21 may be provided in the resistance sensor 11 in a rounded state. Also, a protective coating (not shown) may cover the base film 21, and a protective structure may be provided with a porous structure permeable to oil. The specific configuration of the resistance sensor 11 will not be described in detail here. Those skilled in the art will appreciate that various other types of resistance sensors as well as such resistance sensors may be used.

The communication cable 12 may be connected to a pollution analysis console as will be described later. Communication between the oil leak detection device and the contamination analysis console C can be performed using, for example, the RS-485 communication method. As is well known, the RS-485 communication method has a transmission distance of about 1,200 meters at 100 kbps, so that it can be used to install a large number of oil leak detection devices in a wide area. In addition, since it does not use ground for data transmission, it has an advantage that long distance transmission is possible. It is preferable that the communication cable 12 is wrapped with a cloth or embedded in the ground in a state where it is inserted into a cable protection tube to prevent damage.

Alternatively, a plate 13 having a plurality of fine holes 13a may be disposed on the upper side of the funnel 10. The inside of the truncated conical section 10a of the funnel 10 becomes empty when the leakage sensing device 1 is buried in the ground with the plate 13 being installed. The leaked oil is drawn into the interior of the funnel 10 through the fine holes 13a of the plate 13 and is sensed by the resistance sensor 11. [ In the case where the plate 13 is provided, it is possible to reduce the possibility that the resistance sensor 11 is damaged or the funnel 10 itself is damaged due to a change in the underground environment.

On the contrary, when the plate 13 is not provided, the soil fills the interior of the truncated conical portion 10a of the funnel 10. When the soil fills the interior of the funnel 10, the oil leaked to the soil can directly contact the resistance sensor 11, while the resistance sensor 11 can be damaged by contact with the soil. Therefore, it is preferable that the resistance sensor 11 is surrounded by the epoxy 11a.

3 is a schematic block diagram of an example of a petroleum handling facility including an apparatus for detecting a leaking oil in a soil according to the present invention.

Referring to the drawings, an oil storage tank T is provided on an earth surface, and an infusion pump P and an oil distribution apparatus D corresponding to facilities for handling oil are arranged around the oil storage tank T do. The infusion pump P and the storage tank T are connected through an infusion pipe 31 and the oil dispenser D and the storage tank T are connected through a delivery pipe 32.

The oil leakage detection device 1 according to the present invention is buried in the ground below the oil storage tank T, the injection pump P and the oil distribution device D. Although the oil leakage sensing device 1 is shown as being embedded in the lower part of the infusion pump P and the lower part of each of the oil distribution devices D in the example shown in the figure, in practice, not only the lower part of the storage tank T A plurality of oil leakage sensing devices 1 can be installed at a plurality of points throughout the entire oil handling facility.

The communication cable 12 extending from the resistance sensor 11 of the oil leak detection device 1 is connected to the analysis console C in the central control center. The operator can monitor whether the oil leakage is detected in the oil leakage detection device 1 through the analysis console C. [ If oil leaks are detected, the operation of the facility can be stopped immediately and countermeasures can be taken to prevent contamination.
