When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1: as shown in FIG. 1, the hydrocarbon oil leakage detection device of the present invention comprises a main controller 1 and a sensing line 2 electrically connected to the main controller 1, and can further comprise a human-computer interaction system (not shown), and the detection device is controlled by the human-computer interaction system.
The sensing line 2 comprises two conductive electrodes 21 respectively arranged at two ends of the sensing line 2, a conductive circuit (not shown) connected with the two conductive electrodes 21, and an induction layer 22 arranged on the surface of the conductive circuit and respectively connected with the two conductive electrodes 21; the sensing layer 22 is made of graphene material.
In preparing the sensing layer 22, a graphene material may be applied to the surface of the conductive circuit to form the sensing layer 22.
The main controller 1 is configured to collect a voltage between the two conductive electrodes 21, and determine whether a leakage condition exists according to a collected voltage value.
The main controller 1 comprises a divider resistor, a voltage acquisition module 11 and a microcontroller 12 electrically connected with the voltage acquisition module 11.
The divider resistor is connected with the sensing wire 2 in series; the voltage acquisition module 11 is configured to acquire voltages at two ends of the sensing line 2 and send acquired voltage values to the microcontroller 12; the microcontroller 12 is configured to receive the voltage value sent by the voltage acquisition module 11, and compare the voltage value with a preset value to determine whether there is a leakage condition. Specifically, the original voltage value and the upper voltage limit value of the sensing line 2 may be set, and it is determined that a leakage condition exists when the voltage value received by the microcontroller 12 exceeds the upper voltage limit value, otherwise, it is determined that the leakage condition is normal.
The microcontroller 12 is a MCU.
In order to find the leakage condition in time, an alarm can be arranged in the detection device and electrically connected with the microcontroller 12, and when the microcontroller 12 judges that the leakage condition exists, the microcontroller 12 controls the alarm to be turned on to remind a worker of paying attention.
In order to supply power to the detection device so that the detection device can work normally, a power interface can be arranged in the main controller 1 and connected with an external power supply to supply power to the detection device. It is also possible to directly build a power supply in the circuit of the detection device to supply power to the device. Or in order to prevent the continuous work caused by power failure, an external power supply and an internal power supply can be simultaneously arranged.
The human-computer interaction system can set a preset voltage value in the memory of the microcontroller 12, and receive and display real-time information of the detection device, and discover leakage problems in time.
The graphene has lipophilicity and good solubility in a nonpolar solvent, and can be quickly adsorbed and dissolved in a graphene material when the hydrocarbon oil leaks, so that the detection device can quickly respond. When the graphene coating is contacted with hydrocarbon oil, the conductivity of the graphene can be reduced by the hydrocarbon oil, so that the impedance of the graphene is increased, the voltage is influenced, the microcontroller 12 judges the leakage condition through the change of the voltage, and alarm information is output.
Graphite alkene has high carrier mobility, and electric conductivity is strong, and sensitivity is high to graphite alkene's electron mobility receives temperature variation's influence less, is applicable to various environment, consequently the utility model discloses a detection ring border is extensive. And after the graphene is contacted with the hydrocarbon oil, chemical impurities are embedded in the graphene, the carrier mobility of the graphene is greatly reduced due to scattering of oil impurities, the resistivity of the sensing line 2 is influenced and changed, and the characteristic that the resistivity is changed after the graphene is contacted with the hydrocarbon oil is utilized to detect the graphene-based sensor.
For proving the utility model discloses a detection device can use repeatedly, and the hydrocarbon oil is paintd to response layer 22 repeatedly to the special adoption to the resistivity change value of the induction line before and after paintd is paintd at every turn in the detection. As shown in fig. 2, which is a test graph of the change in resistivity after the hydrocarbon oil is contacted with the sensor line 2. Wherein the original value R is the original resistance value of the sensing wire 2 that has not contacted the hydrocarbon oil, the 1 st coating is the first contact of the sensing layer 22 with the hydrocarbon oil, and R1 is the resistance value of the sensing wire 2 that has contacted the hydrocarbon oil; the 1 st recovery is after the sensing layer 22 recovers after the sensing layer 22 first contacts hydrocarbon oil (the recovery refers to that the leakage of the hydrocarbon oil is removed), R2 is the resistance value of the sensing line 2 after the 1 st recovery, and so on, and the change of the resistivity of the sensing line 2 gradually tends to be stable after the 4 th hydrocarbon oil smearing and recovery. However, at this time, the resistance of the sensor layer 22 after contact with hydrocarbon oil is still significantly different from the resistance of the sensor line 2 after recovery. The graph shows that the resistivity change of the sensing line 2 after the sensing line is contacted with the hydrocarbon oil for the first time is the largest, the resistivity change of the sensing line 2 after the sensing line is coated for the 4 th time tends to be stable, and at the moment, the resistance value of the sensing line 2 after the sensing line is contacted with the hydrocarbon oil is still much larger than the resistance value of the sensing line 2 after the sensing line is recovered, so that the resistance value can still be used as a detection basis.
Graphene has electric conductivity, the utility model discloses a regard graphite alkene as the pivot that switches on between two conducting electrodes 21, graphite alkene response layer 22 on conducting circuit contacts the back with hydrocarbon oil, the resistivity receives the influence, the impedance increase, thereby the magnitude of voltage that makes two conducting electrodes 21 output changes, voltage acquisition module 11 gathers the voltage between two conducting electrodes 21, voltage signal transmission to MCU that will gather again, MCU is as the judgement foundation according to the change signal of voltage, thereby judge whether there is the leakage condition.
The utility model discloses a hydrocarbon oil leakage detection device's theory of operation as follows: when there is hydrocarbon oil to leak when detecting range, the hydrocarbon oil of leakage is adsorbed by the graphite alkene of response layer 22 fast, imbed chemical impurity in the graphite alkene, because oil impurity scattering, lead to graphite alkene carrier mobility to descend, the resistance grow, voltage acquisition module 11 gathers the voltage between two conducting electrodes 21, and send the collection result for microcontroller 12, microcontroller 12 receives the voltage acquisition value that voltage acquisition module 11 sent, and compare this value with predetermineeing the voltage value, when received voltage value exceedes voltage upper limit value, then judge that there is the leakage condition, and control the alarm and report to the police in order to remind the staff in time to overhaul. When the hydrocarbon oil leakage does not occur, the voltage value between the two conductive electrodes 21 is not changed, and the microcontroller 12 compares the received voltage value with the preset voltage value, and the voltage value does not exceed the upper limit value, so that the leakage condition is judged to be absent.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
