Technical Field

[0001] This utility model relates to the field of vehicle fuel tank monitoring technology, specifically to a fuel monitoring device for railway engineering vehicles. Background Technology

[0002] The main power source for all large track maintenance machinery is diesel engines. Fuel expenditure plays a crucial role in the cost control of the large machinery section of the railway bureau. With the expansion of the railway network, the workload of track maintenance machinery has increased year by year. At the same time, with the rise in oil prices in recent years, the proportion of fuel costs for large machinery in the cost expenditure of the large machinery operation and supervision section has gradually increased. Accurately calculating fuel consumption and controlling fuel costs are important means of controlling the cost of track maintenance machinery.

[0003] Currently, most large road maintenance vehicles have hollow fuel tanks. When the vehicle moves or brakes, the fuel inside the tank will be subject to significant impact and shaking. This will cause errors in the monitoring equipment's measurement of the fuel level, affecting the vehicle's equipment's accurate calculation and judgment of fuel consumption, thus reducing its practicality.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] See Figures 1-4 As shown, this utility model provides a fuel monitoring device for railway engineering vehicles, including a fuel tank 1, a monitoring host 2, and a fuel level sensor 3. The fuel tank 1 is provided with several flow stabilizing plates 4, which divide the internal space of the fuel tank 1 into several interconnected oil storage chambers. Each oil storage chamber is provided with a float 5 that can move up and down. A fuel inlet 7 is provided on one side of the fuel tank 1. The inner wall of the fuel tank 1 is provided with an anti-theft structure to prevent fuel theft. The fuel level sensor 3 is fixedly installed in the middle of the upper surface of the fuel tank 1, and the detection end of the fuel level sensor 3 extends into the interior of the fuel tank 1.

[0024] As an optional implementation, the flow stabilizer plate 4 is provided with several through holes 8, and each flow stabilizer plate 4 is provided with a flow groove 9 at its lower end, so that the oil injected into the oil tank 1 can flow smoothly between the several flow stabilizers 4 and avoid large-scale shaking of the oil.

[0025] Reference Figure 2 As shown, the float plate 5 is a hollow box-shaped structure, and each float plate 5 has a support foot 13 fixedly connected to the four corners of its bottom surface. The hollow structure of the float plate 5 allows it to float smoothly in the oil and stabilize the swaying of the liquid surface. At the same time, the support foot 13 allows a certain gap between the float plate 5 and the bottom of the oil tank 1, which facilitates the oil to rush into the bottom of the float plate 5 and lift it up.

[0026] As an optional implementation, the float plate 5 is fixedly connected to both sides of the middle section with sliding sleeves 10 that pass through it, and two sliding rods 11 that are inserted into the sliding sleeves 10 are fixedly connected between the upper and lower side walls of the oil tank 1, which can make the float plate 5 more stable when moving up and down, and at the same time prevent the float plate 5 from swinging with the oil.

[0027] Reference Figure 3As shown, the anti-theft structure includes a guide pipe 6 fixedly connected to the inner wall of the fuel tank 1. The length of the guide pipe 6 is adapted to the height of the fuel tank 1, and the upper end of the guide pipe 6 is designed with a large diameter and connects to the fuel inlet 7. A filter screen 14 is fixedly connected to the upper side of the inside of the guide pipe 6, which allows the oil to be smoothly injected into the bottom of the fuel tank 1 through the guide pipe 6. At the same time, the filter screen 14 can effectively prevent criminals from stealing oil from the fuel inlet 7 through the conduit.

[0028] Specifically, one of the float plates 5 is fixedly connected to an insert sleeve 12 that is fitted onto the detection end of the oil level sensor 3, which allows the float plate 5 located at the oil level sensor 3 to move freely up and down, and allows the oil level sensor 3 to successfully monitor the oil level.

[0029] Reference Figure 4 As shown, the monitoring host 2 consists of an MCU controller, a power module, an tilt sensor, a locomotive operating condition acquisition module, a human-machine interface, an RS485 module, a 4G communication module, and a USB data transfer and alarm module. The output terminals of the oil level sensor 3, the tilt sensor, and the locomotive operating condition acquisition module are all electrically connected to the input terminal of the MCU controller. The input terminal of the power module is electrically connected to the on-board 24V power supply, and the power module supplies power to all electrical equipment. The MCU controller is electrically connected to the RS485 module, the 4G communication module, and the USB data transfer and alarm module. The RS485 module is electrically connected to the human-machine interface. The oil level sensor 3 measures the change in oil level in the oil tank 1 in real time, and the tilt sensor monitors the change in angle of the oil tank 1 in real time. The change information is fed back to the industrial tablet PC through the acquisition module. The industrial panel PC monitors and judges signals during the standby, running, and operation phases of large railway maintenance locomotives. Through software algorithms, it accurately determines the fuel consumption of railway engineering vehicles under various working conditions, records and saves the information, and also records and saves the amount of fuel added each time. The data is uploaded to the server for storage via 4G network communication, realizing real-time storage, query, display, and alarm of fuel consumption data, including fuel level, remaining fuel, average fuel consumption, and low fuel alarm.

[0030] The working principle of this utility model:

[0031] When in use, the oil gun is inserted into the oil inlet 7 to inject oil into the oil tank 1. At this time, the oil gradually rises through the gap between the float plate 5 and the inner wall of the oil tank 1. The buoyancy drives the float plate 5 to rise in each oil storage chamber. When the vehicle is moving, several flow stabilizers 4 can effectively prevent the water hammer effect of the oil and reduce the impact force of the oil. At the same time, the float plate 5 can stabilize the upper surface of the oil and avoid large-scale shaking of the upper surface of the oil. At this time, the oil level sensor 3 monitors the relatively stable oil surface in real time, which improves the accuracy of monitoring.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
