A specific oil leakage detection circuit in the detection sensors 3a, 3b, 3c,... Will be described later.

  FIG. 5 shows a cross-sectional structure including the underground tank 15 and the oiling pipe 16 in particular. As described above, the oil supply pipe 16 is provided with the oil supply port 20, oil (gasoline) is supplied from the oil supply port 20, and the oil (gasoline) is stored in the underground tank 15 through the oil supply pipe 16. As shown in the figure, the oil supply pipe 16 also has a double structure, in which a primary pipe 30 made of resin is used as a base pipe, and a secondary pipe 31 made of the same resin is covered with the primary pipe 30. Here, the characteristics of the double structure of the oil supply pipe 16 of this example will be further described.

  FIG. 6 is a perspective view of the oil supply pipe 16 of this example. As described above, the lubrication pipe 16 is covered with the same resin secondary pipe 31 with respect to the resin primary pipe 30, and a gap 32 having a predetermined width is provided between the primary pipe 30 and the secondary pipe 31. Is formed. In the gap 32, the above-described oil leakage detection line 25 is disposed. The primary pipe 30 and the secondary pipe 31 are not limited to thermoplastic resins such as polyethylene and polyamide, and thermosetting resins such as phenol resins and epoxy resins and steel pipes can be used as materials.

FIG. 7A is a cross-sectional view (cross-sectional view taken along line BB in FIG. 6) of the oil supply pipe 16, and FIG. 7B is an enlarged view of a dotted-line circle mark portion A in FIG. As described above, the oil supply pipe 16 has a double structure, and the primary pipe 30 is covered with the secondary pipe 31. In addition, as shown in FIGS. 4A and 4B, the oil leakage detection line 25 is disposed in the gap 32 between the primary pipe 30 and the secondary pipe 31, and oil leakage from the primary pipe 30 is prevented. Detect. The oil leakage detection line 25 is linearly arranged on the lower surface of the primary pipe 30 (upper surface of the secondary pipe 31). Therefore, even if gasoline (oils) flowing in the primary pipe 30 leaks from, for example, a defective portion formed in the primary pipe 30, the leaked gasoline flows down along the outer surface of the primary pipe 30, It is a structure that can be reliably detected by the oil leak detection line 25.
In addition, the secondary pipe 31 serves as a tray, and it is possible to prevent leaked gasoline (oils) from flowing out and contaminating the soil.

  FIG. 8 is a cross-sectional view (cross-sectional view taken along the line CC) of FIG. 7B, and the wiring configuration of the oil leakage detection line 25 disposed in the gap 32 between the primary pipe 30 and the secondary pipe 31 described above. Indicates. As shown in the figure, the oil leak detection line 25 is arranged in a straight line along the lower lower surface of the primary pipe 30 (lower upper surface of the secondary pipe 31) and leaks from a defective portion of the primary pipe 30. Gasoline (oils) can be detected reliably.

  Further, the configuration of the oil leak detection line 25 will be described by enlarging the circle D portion shown in the figure. The oil leak detection line 25 includes an oil absorption part 34 and a detection part 35. The oil absorbing part 34 has a property of absorbing oil such as gasoline, and is made of, for example, a fluororesin film, and the detecting part 35 detects oil sucked by the oil absorbing part 34. In this configuration, as shown in an enlarged schematic diagram of the circle E part of the figure, when oil comes into contact with the detection unit 35 through the oil absorption unit 34, the oil penetrates into the element 36 of the detection unit 35, The resistance value of the detection unit 35 is changed. This change in resistance value is notified to the aforementioned oil leakage detection monitor 28 via the cable 27.

  FIG. 9 shows a structure of a pipe 38 for taking out the oil leakage detection line 25 to the outside. This pipe 38 is basically a double pipe structure composed of the primary pipe 30 and the secondary pipe 31 described above. A wiring extraction part 39 for taking out the oil leakage detection line 25 to the outside is provided. In addition, the above-mentioned normal double pipe, for example, 39 is connected to the pipe 38 shown in the figure before and after, a plurality of these pipes 38 and 39 are connected, and the oil leak detection line 25 is connected to all the double pipes. Route through. The oil leak detection line 25 is made of fluororesin as described above, and is excellent in weather resistance and chemical resistance.

  FIG. 10 is a diagram showing the configuration of the oil leak detection line 25 used in this embodiment. As shown in the figure, the oil leakage detection line 25 used in this example uses an element 36 having a resistance value of the detection unit 35 different depending on the arrangement position. For example, the resistance value of the first predetermined width L1 of the oil leak detection line 25 is set to R36-1, the resistance value of the next predetermined width L2 is set to R36-2, and the resistance value of the next predetermined width L3 is A detection line which is set to R36-3 and whose resistance value changes in order of R36-4, R36-5,. By using the oil leak detection line 25 having such a configuration, it is possible to specify the position where oil such as gasoline has leaked.

  FIG. 11 is a diagram illustrating a circuit configuration (oil leakage detection circuit 40) used in this example. In this case, a signal from the same oil leak detection line 25 is input to the oil leak detection line 25, and the resistance values of the voltage dividing resistors R1, R2, R3,. Thus, an output can be obtained from the position of the transistor Tr corresponding to the oil leakage position. For example, if there is a detection output from the output of the transistor Tr by matching the resistance value of the voltage dividing resistor R with the resistance change of the detection unit 35 (element 36) of the oil leakage detection line 25 at a position where the pipe is present, It can be seen that the oil leaks from the corresponding position.

  Specifically, by making the resistance value of the voltage dividing resistor R1 coincide with the resistance change of the detection unit 35-1 (element 36-1) at the position of the resistor R36-1 of the oil leakage detection line 25, the resistance from the transistor Tr1. If there is a detection output (output 1), it can be seen that oil leaks from the position L1 of the pipe. Further, by making the resistance value of the voltage dividing resistor R2 coincide with the resistance change of the detection unit 35-2 (element 36-2) at the position of the resistor R36-2 of the oil leakage detection line 25, the detection output from the transistor Tr2 ( With output 2), it can be seen that oil leaks from the position L2 of the pipe.

  Similarly, by making the resistance value of the voltage dividing resistor R3 coincide with the resistance change of the detection unit 35-3 (element 36-3) at the position of the resistor R36-3 of the oil leakage detection line 35, the detection output from the transistor Tr3. (Output 3) indicates that oil leaks from the position of L3 of the pipe, and the resistance value of the voltage dividing resistor R4 is detected by the detection unit 35-4 (position of the resistor R36-4 of the oil leak detection line 25). By matching the resistance change of the element 36-4), it can be seen that if there is a detection output (output 4) from the transistor Tr4, oil leaks from the position L4 of the pipe.

  The example shown in FIG. 12 is, for example, a case where there is an oil leak at the position L2 of the pipe. In this case, the resistance value of the detection unit 35-2 (element 36-2) is changed, and the detection output of the transistor Tr2 ( It can be seen from the output 2) that there is an oil leak at the position of the pipe L2.

  Therefore, in this example as well, the piping location to be repaired can be pinpointed in advance, and excavation work, repair work, etc. can be performed efficiently, and this is a double piping system with an extremely effective structure. The predetermined width can be arbitrarily set. For example, the predetermined width can be set as necessary from several cm intervals to several m intervals.

In the above configuration, the processing of this example will be described below.
FIG. 13 is a flowchart for explaining the processing of this example. In the figure, the processing on the left side shows the processing of the detection sensors 3a, 3b, 3c,..., And the processing on the right side shows the processing of the control notification device 1.

  First, the detection sensors 3a, 3b, 3c,... Provided in the oiling stations and underground tank stores A, B, C,... Start monitoring oil leakage (step (hereinafter referred to as ST) 1) ). For monitoring the oil leakage, for example, first, the oil leakage of the underground tank 15 is determined (ST2), and then the oil leakage of the pipe 16 is determined (ST3). Specifically, it is determined whether the detection line 14 provided in the underground tank 15 detects an oil leak in the underground tank 15, and the detection line 25 provided in the pipe 16 detects an oil leak in the pipe 16. Judgment is made based on whether or not to detect.

  For example, when a long period of time has elapsed since the installation of the underground tank 15 and corrosion or pitting occurs, the underground tank 15 of this example has a double-shell structure as described above, and the detection line is between the steel material 15a and the FRP 15c. Since 14 is disposed, when oil (for example, gasoline) leaks due to corrosion or pitting, the detection line 14 immediately detects the oil leak (YES in ST2).

  As soon as an oil leak is detected in the underground tank 15 by the detection line 14, the corresponding detection sensors 3a, 3b, 3c,... Are supplied with the codes of the oil handling station or the underground tank storage A, B, C,. It is added (ST4), and Wi-Fi is used to notify the control notification device 1 that an oil leak has occurred (ST5). At this time, the code information added at the same time is also transmitted to the control notification device 1.

  The control notification device 1 constantly monitors whether there is an oil leak notification from any refueling station or underground tank storage A, B, C,... (Step (hereinafter referred to as STP) 1), When there is the above notification (YES in STP2), the underground tank 15 in which the notification has been made is confirmed (STP3). Specifically, the refueling station or underground tank storage A, B, C,... That received the report is identified from the code information included in the received information, and the place where the oil leaked is the underground tank 15 Or pipe 16 (STP4).

  The control notification device 1 notifies this information to the call center 4 using Wi-Fi. Based on the received information, the call center 4 records, for example, in a database (STP5) and displays necessary information on a display (STP6). FIG. 14 is a diagram showing this display, together with the display of “oil leak information”, information such as the installation address of the oil handling station or underground tank storage A, B, C,. indicate. For example, as a refueling handling station or an underground tank storage where an oil leak has occurred, the display of the refueling handling station “A” and the information on the installation location of the refueling handling station “A” are displayed.

  In addition, the display shows that the place where it occurred is an “underground tank”, and information on the date and time when the oil leak occurred. Therefore, the administrator who sees this display can immediately grasp the installation location of the refueling handling station “A” where the oil leak occurred, and the equipment where the oil leak occurred is the underground tank 15, and the date and time when the oil leak occurred. Can also grasp. Therefore, from the above information, the call center 4 can notify the maintenance company 5 to repair the oil leak, and can direct the worker from the maintenance company 5 to the refueling handling station “A” where the oil leak has occurred.

  On the other hand, the same applies when an oil leak occurs in the pipe 16. For example, corrosion or pitting corrosion occurs in the pipe 16, oil leaks from the primary pipe 30 of the pipe 16, and the primary pipe 30 and the secondary pipe 31. The detection line 25 wired in between detects oil (gasoline) leakage and immediately notifies the detection sensor 3 (YES in ST3). When an oil leak is detected, the detection sensor 3 immediately adds code information, and also adds information indicating that the equipment in which the oil leak has occurred is the pipe 16 (ST6), and notifies the control notification device 1 as described above. (ST7). When oil leakage occurs in the pipe 16, information for specifying the occurrence location in the pipe 16 is also added and notified to the control notification device 1.

  As in the above, the control notification device 1 constantly monitors whether there is a report of oil leakage from any of the refueling stations or underground tank stores A, B, C,... Then, the device that has received the notification is confirmed, and the refueling station or underground tank storage A, B, C, etc. that has been notified is identified from the transmitted code information (STP3), and there is an oil leak. It is determined that the connected device is the pipe 16 (STP4). Furthermore, the generation | occurrence | production location in the piping 16 is specified based on the said information.

  And the information which shows that the oil leak has generate | occur | produced in the oil supply handling place or underground tank storage place and piping 16 which were identified from the code number is notified to the call center 4 using Wi-Fi. Based on the received information, the call center 4 records, for example, in a database (STP7) and displays necessary information on a display (STP8).

  FIG. 15 is a diagram showing an example of this display. In addition to the display of “oil leakage information”, the information of the oil handling center or underground tank storage where the oil leakage has occurred, for example, the underground tank storage “B”, and the installation address thereof is shown. Is displayed. In addition, a display indicating that the place where the oil leak has occurred is “piping” and information on the date and time of occurrence are displayed, and information for specifying the location where the oil leak has occurred is also displayed.

  Accordingly, the call center 4 can immediately grasp the underground tank storage “B” where the oil leak has occurred and the installation location thereof, and the place where the oil leak has occurred is the pipe 16, and the date and time when the oil leak has occurred can also be known. . Further, it is possible to specify the position of the pipe 16 where the oil leak has occurred, and the call center 4 notifies the maintenance company 5 to repair the oil leak, and the maintenance company 5 informs the operator of the underground tank where the oil leak has occurred. Can be directed to reservoir “B”.

  As described above, according to the present invention, when the underground tank 15 or the pipe 16 is corroded or pitted, and an oil leak occurs, the Wi-Fi is used immediately and the call center 4 is transmitted via the control notification device 1. The call center 4 notifies the maintenance company 5 in order to repair the oil leak, and the maintenance company 5 notifies the worker of the oil handling station or underground tank storage “A” to “A” where the oil leak has occurred. The underground tank 15 and the pipe 16 where oil leakage has occurred can be quickly repaired.

  Accordingly, human resources for repair can be dispatched immediately to the installation location of the equipment, and problems such as equipment troubles such as equipment leaks and soil contamination can be prevented in advance. In addition, since the device in which the oil leak has occurred can be specified, and the position where the oil leak has occurred can be specified, the repair work at the site can be quickly performed.

  In the above description of the embodiment, Wi-Fi is used for communication between the control notification device 1 and the detection sensors 3a, 3b, 3c,..., Communication between the control notification device 1 and the call center 4, etc. Of course, it is not limited to Fi, and other communication networks may be used.
