Description

Technical Field

[0001] This application relates to the field of refueling equipment technology, specifically to a locomotive fuel dispensing device. Background Technology

[0002] Traditional diesel refueling systems in existing railway locomotive depots typically consist of a fixed refueling machine, a separate dispensing room, and a back-end management computer. In this system, refueling operators must first input or verify order information (such as locomotive number and refueling volume) on the back-end management system before proceeding to the refueling machine to perform the actual refueling operation. Because the management terminal and the refueling equipment are often some distance apart, refueling operators must frequently travel between the two locations, resulting in cumbersome procedures, low efficiency, and an increased risk of human error.

[0003] As equipment ages, the drawbacks of the original refueling system become increasingly apparent: the failure rate of core components remains high even after multiple replacements; the communication module has poor stability, often leading to data transmission interruptions or delays; the accuracy of mechanical flow meters has decreased, making it difficult to achieve precise measurement; and the traditional manual operation mode relies on on-site manual control, resulting in slow refueling speeds that cannot meet the operational needs of modern locomotive depots with high flow rates and high frequencies.

[0004] Currently, there has been some progress in the field of liquid refueling technology both domestically and internationally, such as the adoption of high-precision flow sensors, integrated control systems, and remote data interaction solutions. However, there is still a lack of specifically optimized solutions for the special scenarios of railway locomotive depots, which require compatibility with high-flow-rate diesel refueling (hundreds of liters per minute or more), strong environmental adaptability, high safety, and seamless integration with existing railway management systems. Existing refueling devices often do not fully consider the actual needs of locomotive refueling operations, such as multi-station parallel operation, real-time reporting of refueling data to the railway dispatching system, and high explosion-proof requirements.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0012] In some embodiments of this disclosure, a filter is connected in series in the oil inlet line.

[0013] In some embodiments of this disclosure, the oil pipeline includes a first oil pipeline and a second oil pipeline connected in parallel; the first oil pipeline is connected in series from upstream to downstream with a first ball valve and a first flow meter electrically connected to the control module; the second oil pipeline is connected in series with a second flow meter electrically connected to the control module, a second ball valve connected in series downstream of the second flow meter and correspondingly in parallel, and a solenoid valve electrically connected to the control module.

[0014] In some embodiments of this disclosure, a manual ball valve is connected in series in the oil outlet pipeline.

[0015] One or more technical solutions provided in the embodiments of this application have at least one of the following technical effects or advantages: 1.

[0027] This application provides a locomotive fuel dispensing device that, through a management unit connected to the China Railway Logistics Cloud Platform network, achieves the technical effect of improving refueling efficiency; by setting a partition and an emergency stop button between the fuel supply module and the control module, the safety of the refueling machine is ensured; and by setting a cover plate on the outside of the display manager and the start keyhole, the safety of the refueling equipment is protected.

[0028] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This example discloses a locomotive fuel dispensing device; see [link to relevant documentation]. Figures 1 to 2 The device includes a housing 1, a fuel supply module 2 located inside the lower side of the housing 1, a control module 3 located inside the housing 1 and above the fuel supply module 2, and a management unit 4 electrically connected to the control module 3. The housing 1 provides support and protection for the entire device, and its surface has heat dissipation holes and openings for display devices. The fuel supply module 2 is connected to the fuel tank 51 of the gas station, and there is a submersible pump 52 between the fuel supply module 2 and the fuel tank 51. Under the joint action of the control module 3 and the management unit 4, the fuel in the fuel tank 51 is supplied to the locomotive.

[0030] The management unit 4 includes a display manager 41 located on the other side of the control module 3 and hinged to the device housing 1, a scanning component 42 located inside the device housing 1 and behind the display manager 41, and a start keyhole 43 located below the display manager 41 and embedded in the device housing 1. The fuel supply module 2 is electrically connected to the control module 3, and the management unit 4 is connected to the China Railway Logistics Cloud Platform network. The management unit 4 is the most important control device of this system, including a display manager 41 for interacting with the refueling operator, a scanning component 42 for scanning refueling reports, and a start keyhole 43 for starting the refueling process. The display manager 41 is connected to the device housing 1 via a hinge on its side, providing not only a more efficient maintenance and replacement path for itself but also a more convenient maintenance method for the scanning component 42 behind it. The display manager 41 is electrically connected to the scanning component 42 and can display train number information. It is connected to the China Railway Logistics Cloud Platform network through its internal fiber optic interface to submit reports to the back-end management system. The display manager 41 is also electrically connected to the control module 3, communicating with each other about the refueling status. The scanning component 42 is a camera that takes pictures of the reports and transmits them to the display manager 41, thereby uploading them to the background management system. The start keyhole 43 is the device's fuel supply start device; by using a matching key, the management unit 4 recognizes the correct refueling command, thus initiating the refueling process.

[0031] refer to Figure 6 The management unit 4 is equipped with a power-off protection circuit to protect system data. It uses an internal battery to continue supplying power to the motherboard during a sudden power outage, ensuring that system data is not lost and supporting the display of the last transaction data for 15 minutes.

[0032] The device housing 1 includes a report placement drawer 11 located below the management unit 4, and a toolbox 12 located below the report placement drawer 11. The report placement drawer 11 stores reports inside the device, preventing external interference from hindering report submission. Furthermore, the report placement drawer 11 is closer to the scanning component 42, allowing for faster report uploading. The toolbox 12, located on the lower side of the device, can store commonly used tools.

[0033] The device housing 1 includes a partition 13 for separating the fuel supply module 2 and the control module 3, and a cover 14 located outside the display manager 41 and the start keyhole 43. Both the partition 13 and the cover 14 are components that ensure the safety of the device. The partition 13 separates the fuel supply module 2 and the control module 3, preventing static electricity in the circuit from entering the filling area, thereby preventing fires or even explosions caused by static electricity igniting fuel. The cover 14 of the management unit 4 has a keyhole, which, by enclosing the management unit 4, prevents damage to the equipment from the external environment or unauthorized personnel.

[0034] The control module 3 includes a main board 31 electrically connected to the management unit 4, a drive board 32 electrically connected to the main board 31, and an emergency stop button 33 electrically connected to the main board 31 and embedded in the device housing 1, which also controls the power supply status of the device. The main board transmits information from the fuel supply module 2 to the management unit 4 and receives refueling commands from the management unit 4. The drive board 32, controlled by the main board 31, supplies external power to the main board 31, the management unit 4, the submersible pump 52, and the fuel supply module 2. The emergency stop button 33 is located between the external power supply and the drive board 32, controlling the power supply to the entire device by closing or opening it, and promptly cutting off the circuit in case of fuel leakage to prevent fire.

[0035] See Figure 3 , Figure 4 The fuel supply module 2 includes, in sequence, an inlet fuel line 21, a delivery fuel line connected in series with the inlet fuel line 21, and an outlet fuel line 23 connected in series with the delivery fuel line. The connections between the pipes in this design are sealed with gaskets to effectively prevent fuel leakage. Static electricity bridging plates are used between flanges, and the fuel dispenser has a grounding busbar to ensure proper grounding. All electrical components in the hydraulic area are explosion-proof, and all wiring in the hydraulic area is completed in explosion-proof junction boxes. An isolation zone exists between the hydraulic area and the computer box, complying with the requirements of national standard GB / T22380.1.

[0036] The oil inlet line 21 includes a filter 211. The oil pumped from the gas station tank 51 is filtered through the filter 211 to prevent impurities from being added to the receiving container 54 through the oil supply module 2.

[0037] The oil pipeline includes a first oil pipeline 221 and a second oil pipeline 222 connected in parallel with the first oil pipeline 221. The first oil pipeline 221 includes, in sequence, a first ball valve 2211 and a first flow meter 2212 connected in series with the first ball valve 2211 and electrically connected to the control module 3. The second oil pipeline 222 includes, in sequence, a second flow meter 2221 electrically connected to the control module 3, a second ball valve 2222 connected in series with the second flow meter 2221, and a solenoid valve 2223 connected in series with the second flow meter 2221 and in parallel with the second ball valve 2222, and electrically connected to the control module 3. This oil circuit design primarily uses one path containing solenoid valve 2223 for refueling; when solenoid valve 2223 malfunctions, it can be replaced by one path through the second ball valve 2222 for refueling; when the second flow meter 2221 malfunctions, it can be replaced by one path through the first ball valve 2211 and the first flow meter 2212 for refueling. This design prevents refueling from being impossible when the refueling device is damaged.

[0038] The oil outlet line 23 includes a manual ball valve 231. The manual ball valve 231 controls whether fuel can flow out of the equipment.

[0039] When using, such as Figure 5As shown, the refueling operator inserts the fuel nozzle 53 into the receiving container 54, uses a key to open the cover 14, and places the report into the report placement drawer 11. At this time, the scanning component 42 takes a picture of the report and transmits it to the display manager 41. The report photo in the display manager 41 is then uploaded to the background management system via optical fiber. After confirmation by the background management system, the display manager 41 displays information such as refueling time, refueling amount, and train number, and synchronizes this information with the background management system.

[0040] Insert the ignition key into the ignition keyhole 43 and turn it. At this time, the display manager 41 receives the refueling signal. The display manager 41 instructs the drive board 32 to supply power to the submersible pump 52 and the solenoid valve 2223 through the main board 31 of the control module 3. At this time, the submersible pump 52 operates, the solenoid valve 2223 opens, and the fuel passes through the filter 211, the second flow meter 2221, the solenoid valve 2223, and the manual ball valve 231 to the fuel nozzle 53 and inject the fuel into the receiving container 54. During this process, the second flow meter 2221 transmits the fuel refueling amount to the main board 31 through the flow sensor. The main board 31 then synchronizes the refueling amount to the display manager 41 so that the refueling operator can see it intuitively. The display manager 41 also uploads the refueling amount to the background management system so that the railway transportation management system can monitor the refueling machine in real time.

[0041] When refueling is finished, the main control board of the management unit 4 notifies the drive board 32 to disconnect the power supply to the submersible pump 52 and the solenoid valve 2223. The refueling operator puts the refueling nozzle 53 back in place, locks the cover plate 14, and the refueling process ends.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
