Description

Technical Field

[0001] This application relates to the field of electrostatic detection technology for oil guns, and in particular to a novel electrostatic detection device for oil guns. Background Technology

[0002] During the daily operation of gas stations, the fuel nozzles are prone to accumulating static electricity due to contact and friction with refueling vehicles or people. If the static electricity is not released in time, it may cause sparks during refueling, posing a serious safety hazard.

[0003] Currently, most gas stations use manual testing. Operators need to open the hydraulic compartment door of the fuel dispenser and use measuring instruments to test the resistance between the fuel nozzle and the grounding busbar of the fuel dispenser. When the test result is lower than the set resistance threshold, the fuel nozzle is considered to have normal electrostatic discharge function. Although this method plays a role in electrostatic detection to some extent, the existing inspection method requires opening the fuel dispenser body. Since the process of opening the fuel dispenser body and connecting the measuring instruments is cumbersome, the testing efficiency is low, which may affect the normal operation of refueling services and even prolong customer waiting time. Utility Model Content

[0004] The purpose of this application is to provide a novel electrostatic detection device for fuel dispensers, which has the advantages of improving detection efficiency. It solves the problem that existing inspection methods require opening the fuel dispenser body during detection. The process of opening the fuel dispenser body and connecting the measuring instrument is cumbersome, resulting in low detection efficiency, which may affect the normal operation of refueling services and even prolong customer waiting time.

[0005] The novel electrostatic precipitator for fuel dispensers provided in this application adopts the following technical solution: A novel electrostatic precipitator for fuel dispensers includes a fuel dispenser body. A detection device body is fixedly connected to one side of the fuel dispenser body. A detection port is opened on one side of the surface of the detection device body. A first operating module is fixedly connected to the side of the surface of the detection device body away from the detection port. A first display screen is fixedly connected to the upper surface of the detection device body. An indicator light is fixedly connected to the upper end of the detection device body. A transmission antenna is fixedly connected to the upper side of one side of the detection device body. A connector is fixedly connected to one side of the bottom of the detection device body. A wire is fixedly connected to the grounding busbar of the fuel dispenser body. The end of the wire away from the fuel dispenser body is fixedly connected to the connector.

[0006] By adopting the above technical solution, the detection device body is fixedly connected to the fuel dispenser body to form an integrated structure. The surface of the detection device body is equipped with a first operation module and a first display screen. Operators can easily control the detection process through the first operation module and view the detection results in real time through the first display screen. The operation is convenient and intuitive. The design of the detection port allows the fuel nozzle to be quickly inserted for detection without complicated preparation work, improving detection efficiency. An indicator light is fixedly connected to the upper end of the detection device body. When an abnormality is detected, the indicator light will light up immediately to remind the operator to deal with it in time, enhancing the safety of the gas station. Through the transmission antenna, the detection device can transmit the detection data to the background management system in real time, which is convenient for managers to remotely monitor and analyze, and promptly discover and deal with potential safety hazards. The detection device body is fixedly connected to the grounding busbar of the fuel dispenser body through a wire, ensuring a stable and reliable electrical connection between the detection device and the fuel dispenser. This allows the detection device to measure the resistance value between the fuel nozzle and the grounding busbar, thereby more accurately determining whether the electrostatic discharge function of the fuel nozzle is normal.

[0008] By adopting the above technical solution, the fixing block firmly connects the oil pipe to the fuel dispenser body, preventing the oil pipe from becoming loose due to shaking or pulling, reducing the risk of oil leakage, and improving equipment safety.

[0009] Preferably, a placement slot is provided on one side of the fuel dispenser body.

[0010] By adopting the above technical solution, the placement slot can be used to store the fuel nozzle, avoiding damage caused by the fuel nozzle being placed randomly.

[0011] Preferably, two second displays arranged in a mirror image are fixedly connected to the upper surface of the fuel dispenser body, a card reader is fixedly connected to one side of the fuel dispenser body, two second operating modules arranged in a mirror image are fixedly connected to the fuel dispenser body, and an emergency stop button is fixedly connected to the fuel dispenser body.

[0012] By adopting the above technical solution, the two mirror-distributed second displays can simultaneously display different information. One screen can display core data such as transaction amount and fuel volume, while the other screen displays promotional activities, advertisements, or operation guides, improving information transmission efficiency. The two operation modules can control different functions separately, avoiding misoperation and improving operation efficiency. The emergency stop button is located in a conspicuous position on the surface of the fuel dispenser, making it easy for operators to quickly identify and press in an emergency, and can immediately cut off the power to the fuel dispenser in an emergency to prevent the accident from escalating.

[0013] Preferably, the refueling nozzle is movably positioned inside the detection port.

[0015] Preferably, the inner wall of the detection port is provided with copper foil.

[0016] By adopting the above technical solution, the copper foil has a low resistivity and covers the inner wall of the detection port, forming contact with the oil filling end of the fuel nozzle. The copper foil is connected to the detection circuit, which can measure the resistance value between the fuel nozzle and the grounding terminal in real time. If the resistance is greater than the industry standard threshold, the indicator light will light up and trigger an alarm to prevent refueling.

[0017] Preferably, the oil injection end of the refueling gun is in contact with the copper foil.

[0018] By adopting the above technical solution, the copper foil is connected to the detection circuit, the oil injection end of the fuel nozzle contacts the copper foil, and the resistance value between the oil injection end and the grounding end is measured in real time.

[0019] Preferably, the fuel dispenser body and the detection device body are electrically connected.

[0020] By adopting the above technical solution, the resistance value is measured when the fuel nozzle comes into contact with the copper foil, and the detection result is transmitted to the fuel dispenser body to control the start and stop of the fuel pump.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This novel electrostatic discharge (ESD) detection device for fuel dispensers integrates the device body with the fuel dispenser body into a single structure. Through components such as a detection port, indicator light, and transmission antenna, it enhances operational convenience, detection efficiency, and safety. The detection port's inner wall is lined with copper foil. When the fuel dispenser is inserted, its injection end directly contacts the copper foil, allowing for real-time measurement of the resistance between the fuel dispenser and the grounding terminal. This accurately determines whether the fuel dispenser's ESD discharge function is functioning correctly. If an abnormal resistance is detected, the indicator light immediately illuminates, effectively alerting the operator to take timely action and preventing the fuel pump from starting, thus avoiding potential safety hazards. Simultaneously, the detection device transmits the detected data via the antenna. Data is transmitted in real time to the back-end management system, facilitating remote monitoring and analysis by managers to promptly identify and address problems. Furthermore, the second display screen, card reader, operating module, and emergency stop button on the fuel dispenser further enhance its functionality and safety. The second display screen can simultaneously show different information, improving information transmission efficiency; the card reader supports convenient payment; the dual-zone operating module prevents accidental operation; and the emergency stop button can quickly cut off power in emergencies to prevent accidents from escalating. Through structural optimization and functional integration, this device improves the safety management level and operational convenience of gas stations, providing strong support for the safe and efficient operation of refueling.

[0025] Example 1: A novel electrostatic detection device for oil guns, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a fuel dispenser body 1, with a detection device body 2 fixedly connected to one side of the fuel dispenser body 1. The detection device body 2 and the fuel dispenser body 1 are fixedly connected to form an integrated structure. A detection port 3 is provided on one side of the surface of the detection device body 2. The design of the detection port 3 allows the fuel nozzle to be quickly inserted for detection without complicated preparation, improving detection efficiency. A first operation module 4 is fixedly connected to the side of the surface of the detection device body 2 away from the detection port 3. The operator can easily control the detection process through the first operation module 4. A first display screen 5 is fixedly connected to the upper surface of the detection device body 2, allowing real-time viewing of the detection results. An indicator light 6 is fixedly connected to the upper surface of the detection device body 2. When an abnormality is detected, the indicator light 6 will immediately illuminate. This system reminds operators to handle issues promptly, enhancing the safety of gas stations. A transmission antenna 7 is fixedly connected to the upper side of the detection device body 2. Through the transmission antenna 7, the detection device can transmit detection data to the back-end management system in real time, facilitating remote monitoring and analysis by management personnel, enabling timely detection and handling of potential safety hazards. A connector 8 is fixedly connected to the bottom side of the detection device body 2. A wire 9 is fixedly connected to the grounding busbar of the fuel dispenser body 1. The end of the wire 9 furthest from the fuel dispenser body 1 is fixedly connected to the connector 8. The detection device body 2 is fixedly connected to the grounding busbar of the fuel dispenser body 1 via the wire 9, ensuring a stable and reliable electrical connection between the detection device and the fuel dispenser. This allows the detection device to measure the resistance value between the fuel nozzle and the grounding busbar, thereby more accurately determining whether the electrostatic discharge function of the fuel nozzle is normal.

[0026] A fixing block 10 is fixedly connected to the upper end of one side of the fuel dispenser body 1, and an oil pipe 11 is fixedly connected to the bottom end of the fixing block 10. The end of the oil pipe 11 away from the fixing block 10 is fixedly connected to the fuel nozzle 12. The fixing block 10 firmly connects the oil pipe 11 to the fuel dispenser body 1, preventing the oil pipe 11 from becoming loose due to shaking or pulling, reducing the risk of oil leakage, and improving equipment safety. A placement slot 13 is provided on one side of the fuel dispenser body 1. The placement slot 13 can be used to store the fuel nozzle 12, preventing damage caused by random placement of the fuel nozzle 12.

[0027] Example 2: A novel electrostatic detection device for oil guns, referring to... Figure 1 , Figure 4 and Figure 5Two mirror-shaped second display screens 14 are fixedly connected to the upper surface of the fuel dispenser body 1. These two screens can simultaneously display different information; one screen can display core data such as transaction amount and fuel volume, while the other displays promotional activities, advertisements, or operation guides, improving information transmission efficiency. A card reader 15 is fixedly connected to one side of the fuel dispenser body 1. Two mirror-shaped second operation modules 16 are also fixedly connected to the surface of the fuel dispenser body 1. These modules can control different functions separately, avoiding misoperation and improving operational efficiency.

Located in a prominent position on the surface, the emergency stop button 17 allows operators to quickly identify and press it in an emergency, immediately cutting off the fuel dispenser's power and preventing the accident from escalating. The fuel nozzle 12 is movably positioned inside the detection port 3, which allows refueling. The nozzle 12 is inserted directly without manual alignment or angle adjustment, reducing operation time. After insertion, the nozzle 12 automatically triggers detection without additional operation. A copper foil 301 with low resistivity covers the inner wall of the detection port 3, making contact with the oil filling end of the nozzle 12. The copper foil 301 is connected to the detection circuit, allowing real-time measurement of the resistance between the nozzle 12 and the grounding terminal. If the resistance exceeds the industry standard threshold, the indicator light 6 illuminates and an alarm is triggered, preventing refueling.

The resistance between the oil filling end and the grounding terminal is measured in real-time. The fuel dispenser body 1 and the detection device body 2 are electrically connected. When the nozzle 12 contacts the copper foil 301, the resistance value is measured, and the detection result is transmitted to the fuel dispenser body 1 to control the start and stop of the fuel pump.

[0028] It should be noted that the detection device body 2 has an integrated data analysis system, which is used to analyze the measured resistance value to see if it is greater than the industry standard threshold, and to determine whether the electrostatic discharge function of the oil gun is normal.

[0029] The implementation principle of this application embodiment is as follows: Before refueling, the fuel nozzle 12 is inserted into the detection port 3 of the detection device body 2. The copper foil 301 on the inner wall of the detection port 3 contacts the fuel nozzle 12's filling end. The detection device is connected to the grounding busbar of the fuel dispenser body 1 via the wire 9, forming an electrical circuit to measure the resistance value between the fuel nozzle and the grounding busbar. If the resistance value is abnormally greater than the industry standard threshold, the indicator light 6 will light up to alarm, and the detection data will be transmitted to the backend via the transmission antenna 7. The fuel dispenser body 1 will also control the fuel pump to stop working to prevent static electricity hazards. If the resistance is normal, the detection device will display the result on the first display screen 5. The operator can control the detection process through the first operation module 4. After use, the fuel nozzle 12 is placed in the placement slot 13 of the fuel dispenser body 1 for storage. The fixing block 10 ensures that the fuel pipe 11 is firmly connected to the fuel dispenser body 1. In addition, the second display screen 14 on the fuel dispenser body 1 can simultaneously display transaction information or advertisements. The card reader 15 is used for payment operations.
