Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil level measurement, and particularly relates to a fuel tank with an oil level display for a diesel locomotive. Background Technique
[0002] The locomotive has excellent anti - hunting and anti - skidding functions, and has the characteristics of high wheel - circumference efficiency, high adhesion utilization rate, fast starting and acceleration, and good dynamic and braking performances.
[0003] Previously, the locomotive used an iron oil dipstick to measure the oil level through the fuel tank inspection hole, and the operation was rather difficult. The scale of the oil dipstick was not clearly visible, especially when used at night, it was even more difficult. Usually, the train crew needed to prepare their own "chalk" and smear it before measurement to distinguish the oil level. Over time, powder entered the fuel tank. At the same time, the minimum scale of the oil dipstick was 2000 liters, while the safety oil level of the locomotive was 1000 liters. That is, when the oil level was lower than 2000 liters, only subjective estimation could be made.
[0004] Therefore, it is difficult to manually measure the oil level of the diesel locomotive fuel tank, and there are problems such as being unable to read the value when the oil level is below 2000 liters and the inaccuracy of the original liquid level measurement method. Content of the Utility Model
[0005] The purpose of the utility model patent: In order to solve the problems of difficult manual measurement of the oil level of the diesel locomotive fuel tank, being unable to read the value when the oil level is below 2000 liters and the inaccuracy of the original liquid level measurement method, the utility model proposes a fuel tank with an oil level display for a diesel locomotive.
[0006] The utility model is realized through the following scheme:
[0007] A fuel tank with an oil level display for a diesel locomotive, which comprises a fuel tank body, an information display device box and a plurality of magnetostrictive liquid level sensors;
[0008] At least two magnetostrictive liquid level sensors are fixed to the fuel tank body. A plurality of internal thread interfaces and an oil filling position are arranged at the top of the fuel tank body. The lower external thread section of the connection body of each magnetostrictive liquid level sensor is thread - connected with an internal thread interface, and the plurality of magnetostrictive liquid level sensors are arranged in a staggered manner. The top signal lines of the plurality of magnetostrictive liquid level sensors are all connected to the information display device box. The outside of the signal line is covered with a protection tube, and each end of the protection tube is connected with a connecting female head. The connecting female head at one end of the protection tube is thread - connected with the upper external thread section of the connection body of the magnetostrictive liquid level sensor, and the connecting female head at the other end of the protection tube is thread - connected with the external thread section on the information display device box. A circuit board is arranged in the information display device box, and a display screen is embedded on the information display device box. The information collected by the magnetostrictive liquid level sensor is transmitted to the circuit board and displayed on the display screen after information conversion.
[0009] Further, the fuel tank body is a special-shaped fuel tank adapted to the shape of the bottom of the diesel locomotive.
[0010] Still further, the information display device box is fixed to the fuel tank body by a bracket.
[0011] Further, a plug is installed on the internal thread interface that is not connected to the magnetostrictive liquid level sensor.
[0012] Still further, the protection tube is a flexible rubber protection tube.
[0013] Further, the display screen is selected as a low-temperature and low-power consumption display screen.
[0014] Beneficial effects:
[0015] This solution measures the oil level of the fuel tank of a diesel locomotive. The oil level measurement does not require complicated operations. Only by the value on the display screen of the information display device box, the current oil level status can be known. This solution uses a magnetostrictive liquid level sensor for liquid level measurement. With high sensitivity, it can complete real-time monitoring. At the same time, its high measurement accuracy can measure the liquid level when the reading is impossible for less than 2000 liters. And the measured liquid level is much more accurate than the original oil dipstick measurement method, which is beneficial to measuring more accurate data. At least two magnetostrictive liquid level sensors are fixed to the fuel tank body, and the multiple magnetostrictive liquid level sensors are arranged in a staggered manner. Even if the fuel tank body is uneven, the measurement data obtained by combining the two can be comprehensively judged to reduce the measurement error. Moreover, even if one of the magnetostrictive liquid level sensors is damaged, the other magnetostrictive liquid level sensors can still work and continuously measure the oil level, enabling the staff to know the oil level at any time, which is beneficial to the monitoring of the oil level.

[0020] Detailed implementation manner one: A fuel tank with an oil level display for a diesel locomotive, which includes a fuel tank body 1, an information display device box 5, and multiple magnetostrictive liquid level sensors 3;
[0021] At least two magnetostrictive level sensors 3 are fixed to the fuel tank body 1. A plurality of internal thread interfaces 1-1 and an oil filling level 1-2 are arranged at the top of the fuel tank body 1. The lower external thread section of the connection body of each magnetostrictive level sensor 3 is threadedly connected to an internal thread interface 1-1. The plurality of magnetostrictive level sensors 3 are arranged in a staggered manner. The top signal lines of the plurality of magnetostrictive level sensors 3 are all connected to the information display device box 5. The outside of the signal line is coated with a protective tube 4. A connection female head 4-1 is connected to each end of the protective tube 4. The connection female head 4-1 at one end of the protective tube 4 is threadedly connected to the upper external thread section of the connection body of the magnetostrictive level sensor 3. The connection female head 4-1 at the other end of the protective tube 4 is threadedly connected to the external thread section on the information display device box 5. A circuit board is arranged in the information display device box 5. A display screen 5-1 is embedded on the information display device box 5. The information collected by the magnetostrictive level sensor 3 is transmitted to the circuit board and displayed on the display screen 5-1 after information conversion.
[0022] The magnetostrictive level sensor adopts the most advanced magnetostrictive principle, and the measurement accuracy is 0.1 mm. Taking the installation on the fuel tank of the HXN5 locomotive as an example, the installation hole (internal thread interface) is 6 British pipe threads, and the installation height is 1180 mm.
[0023] In this embodiment: at least two magnetostrictive level sensors are fixed to the fuel tank body, and the plurality of magnetostrictive level sensors are arranged in a staggered manner. Even if the fuel tank body is uneven, the measurement data obtained by combining the two can be comprehensively judged to reduce the measurement error. Moreover, even if one of the magnetostrictive level sensors is damaged, the other magnetostrictive level sensors can still work and continuously measure the oil level, enabling the staff to know the oil level at any time, which is beneficial to the monitoring of the oil level and convenient for observing the fuel tank liquid level and oil quantity information at any time during refueling. A plurality of internal thread interfaces are arranged on the fuel tank body, and the magnetostrictive level sensor and the internal thread interface can be quickly disassembled and assembled, which is convenient for maintenance and replacement. The top signal lines of the magnetostrictive level sensors are all connected to the information display device box. The signal line transmits the information collected by the magnetostrictive level sensor to the information display device box. The circuit board built in the information display device box performs signal conversion and output. The display screen embedded on the information display device box is used to display the oil level information. The outside of the signal line is coated with a protective tube. The protective tube is coated outside the signal line to avoid damage to the signal line of the magnetostrictive level sensor. A connection female head is connected to each end of the protective tube to connect the magnetostrictive level sensor box and the information display device box respectively, which is convenient for quick connection and installation and has a stable connection.
[0024] The high-precision liquid level sensors are located at the tops of the two fuel tanks and are installed diagonally. This sensor uses the magnetostrictive principle, which is also known as the Joule effect. It has three manifestations: ① The relative change in the size along the direction of the external magnetic field is called longitudinal magnetostriction; ② The relative change in the size perpendicular to the direction of the external magnetic field is called transverse magnetostriction; ③ The relative change in the volume of the material is called volume magnetostriction. Longitudinal or transverse magnetostriction is collectively referred to as linear magnetostriction, which is specifically manifested as the elongation or shortening of the linear dimension of a ferromagnetic material during magnetization. Transverse and volume magnetostriction are not commonly seen in engineering applications. The magnitude of magnetostriction is represented by the relative elongation of the material:
[0025]
[0026] In the formula, Δl is the change in the length of the material;
[0027] L is the overall length of the material.
[0028] The sign of λ is positive, indicating that as the magnetic field increases, the length change of the material is elongation, which is called positive magnetostriction; conversely, the sign of λ is negative, indicating that as the magnetic field increases, the length change of the material is shortening, which is called negative magnetostriction. The magnetostriction coefficient at saturation is called the saturation magnetostriction coefficient, denoted as λ.
