Description

Technical Field

[0001] This invention relates to the field of fuel refueling technology, and more particularly to a fuel refueling training device for Russian-made equipment. Background Technology

[0002] Due to the lack of training equipment, training for refueling certain types of Russian-imported equipment can only be conducted using actual equipment. This results in low operator error tolerance, poor training effectiveness, and significant wear and tear on refueling components, impacting equipment availability and lifespan. To optimize the existing training model, enabling personnel to quickly master the key points, procedures, and precautions of equipment refueling, and to address the problem of insufficient training equipment to meet training needs, the introduction of a highly realistic fuel refueling training device is imperative. Therefore, we propose a fuel refueling training device for Russian-imported equipment to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fuel refueling training device for Russian equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A refueling training device for Russian equipment includes a support vehicle. A placement frame is rotatably connected to one side of the upper end of the support vehicle. A simulated compartment is fixed to the upper end of the placement frame by two fixing straps. Both ends of the simulated compartment are fixed with end caps. A horizontal level and a vertical level are fixedly installed at the upper end of the simulated compartment. Two partitions are fixed to the circumferential sidewalls inside the simulated compartment, and a connecting pipe runs through the two partitions. A movable empty box is fixed to the bottom of the simulated compartment. The sidewalls inside the simulated compartment are provided with a refueling-venting port, a pressurization port, an accumulator exhaust port, a pipeline exhaust port, and a venting port. A first metal oil pipe is fixedly installed on the refueling-venting port and is located inside the simulated compartment. A first separator is fixedly installed on the pressurization port. A second separator is fixedly installed on the accumulator exhaust port. A second metal oil pipe is fixedly installed on the pipeline exhaust port.

[0006] Preferably, an adjusting bracket is fixed to one side of the lower end of the placement frame, the lower end of the adjusting bracket is fixed to one side of the upper end of the support vehicle, and adjusting wheels are installed on the adjusting bracket.

[0007] Preferably, parking outriggers are fixed at all four corners of the lower end of the support vehicle.

[0008] Preferably, an electrostatic drag strap is fixed to one side of the lower end of the support vehicle.

[0009] Preferably, a steering tow bar is installed at one end of the support vehicle.

[0010] Preferably, an accessory box is placed on the upper end of the support vehicle.

[0011] Preferably, the simulated compartment is made of 316 stainless steel.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The training device's simulation chamber uses a 316 stainless steel shell, compared to the actual equipment which uses an aluminum alloy shell. Under the same training intensity and usage environment, the equipment's weather resistance and structural strength are greatly improved, achieving the high reliability and long service life that the simulation chamber should have as a reusable training equipment.

[0014] 2. The training device's simulation compartment has been equipped with a bottom vent valve, which can be used to vent the internal fuel, effectively solving the problem that the actual equipment does not have a low-level vent valve, which means that some of the internal fuel cannot be completely vented, posing a certain safety risk.

[0015] 3. The end caps on both sides of the simulated compartment adopt a press-fit structure, which is convenient for disassembly and assembly, and facilitates troubleshooting and internal cleaning;

[0016] 4. The actual fuel tank section does not have a level testing device. To ensure the simulated tank section remains level during teaching tasks, one set of longitudinal and one set of transverse levels are installed on the top of the shell. Operators can adjust the front and rear height of the simulated tank section through the support bracket adjustment mechanism and visually check the level indicator to ensure it is in a level position.

[0017] 5. Set a grounding wire connection point on the shell and configure a set of static electricity conductive cable. Connect the compartment grounding point and the static electricity drag strip through the stainless steel clamps at both ends of the cable to achieve the grounding function, ensure the safety of the simulated compartment during the fuel refueling training process, and avoid the operational safety risks caused by static electricity hazards.

[0018] In summary, this invention adopts a highly realistic internal structure and a refueling operation process consistent with the actual equipment, realizing a complete refueling training function. It can completely simulate the refueling action key points and operation process of a certain type of Russian-launched equipment. Compared with the actual equipment, certain structural improvements and technical replacements have been made, which improves reliability and maintenance convenience, and enhances the applicability and testability as a training equipment for the troops.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-4 A refueling training device based on Russian equipment includes a support vehicle 3. The chassis frame of the support vehicle 3 is welded from carbon structural steel profiles and steel plates, and has four tires installed at the front and rear. The tires are high-elasticity solid tires. A placement frame 10 is rotatably connected to one side of the upper end of the support vehicle 3. A simulated compartment 8 is fixed to the upper end of the placement frame 10 by two fixing straps 7. Both ends of the simulated compartment 8 are fixed with end caps 9. Both end caps 9 adopt a press-fit structure and are fixed and sealed to the simulated compartment 8 using fasteners and O-rings, which facilitates cleaning of the internal cavity and maintenance of parts. A transverse level 13 and a longitudinal level 1 are fixedly installed on the upper end of the simulated compartment 8. 4. Two bulkheads 23 are fixed on the side walls of the simulated compartment 8. A connecting pipe 22 is connected through the two bulkheads 23. A movable empty box 18 is fixed at the bottom of the simulated compartment 8. By setting up a fixed cavity area and a movable cavity body, part of the internal space is occupied, and the remaining area can form a closed space with an effective volume of about 107L to meet the relevant technical requirements. This ensures that the positions of the valves on the simulated compartment are consistent with the positions of the valves on the actual fuel tank. At the same time, it solves the problem of volume difference that will occur when the diameter and length are the same because the shell of the simulated compartment is a regular cylinder and the actual fuel tank is an irregular shape.

[0026] The side walls of the simulation compartment 8 are equipped with a fuel filling / venting port 20, a pressurization port 15, an accumulator vent 16, a pipeline vent 17, and a venting port 26. After training, opening the plug on the venting port 26 can completely empty the internal residual fuel, effectively avoiding safety risks. A first metal oil pipe 19 is fixedly installed on the fuel filling / venting port 20, located inside the simulation compartment 8. A first separator 21 is fixedly installed on the pressurization port 15, and fuel is continuously injected into the first separator 21 located inside the simulation compartment 8 through a straight-line vent connector. 0.01 MPa compressed air, after the first separator 21 expands in volume, pressurizes the interior of the simulated compartment 8, and discharges the attached air bubbles generated around the irregular internal structure. This process is repeated multiple times until the fuel is full. At this time, the first separator 21 will be completely compressed due to the pressure difference and will not occupy the internal volume. During long-term storage, an oil and gas adsorbent box is connected to the pressurization port 15 as required. The oil and gas adsorbent stored in the box adsorbs the oil and gas generated by temperature changes during equipment storage. The first separator 21 is made of fluororubber and has a volume of 7L.

[0027] A second separator 24 is fixedly installed on the accumulator exhaust port 16. The accumulator gas supply and pressurization process can be simulated through the accumulator exhaust port 16 and the second separator 24. The process of accumulator pipeline exhaust gas bubbles being discharged can be simulated through the pipeline exhaust port 17 and the second metal oil pipe 25. The second separator 24 is made of fluororubber and has a volume of 5L. The second metal oil pipe 25 is fixedly installed on the pipeline exhaust port 17.

[0028] In this invention, an adjustment bracket 1 is fixed to one side of the lower end of the placement frame 10. The lower end of the adjustment bracket 1 is fixed to one side of the upper end of the support vehicle 3. An adjustment wheel 2 is installed on the adjustment bracket 1. The adjustment bracket 1 consists of a mounting base and an adjustment mechanism. It is assembled from parts and standard parts made of aluminum alloy and high-quality carbon structural steel. When the simulated compartment 8 needs to be adjusted, the leveling operation can be completed by rotating the adjustment wheel 2 in conjunction with the horizontal level 13 and the longitudinal level 14 at the upper end of the shell.

[0029] In this invention, parking legs 4 are fixed at the four corners of the lower end of the support vehicle 3. The parking legs 4 are assembled from high-quality carbon structural steel components and can be adjusted according to the ground conditions to complete the support function.

[0030] In this invention, an electrostatic tow strap 5 is fixed to one side of the lower end of the support vehicle 3. The electrostatic tow strap 5 is installed at the rear of the chassis. It is made of rubber and has built-in copper wires. During installation, one end of the built-in copper wires of the electrostatic tow strap needs to be in contact with the ground, and the other end is connected to the vehicle body through metal fasteners. The grounding resistance is 4Ω, which can ensure smooth conduction of static electricity. At the same time, a set of electrostatic conductive cable is configured. The grounding point of the simulated compartment 8 and the electrostatic tow strap 5 are connected through stainless steel clamps at both ends of the cable to realize the grounding function.

[0031] In this invention, a steering tow bar 6 is installed at one end of the support vehicle 3. The steering tow bar is mainly composed of a tow bar and a steering connecting rod, and is assembled from carbon structural steel parts and fasteners. It plays the role of traction of the whole vehicle and adjustment of the direction of travel.

[0032] In this invention, an accessory box 11 is placed on the upper end of the support vehicle 3. The accessory box 11 is placed on the base frame of the support vehicle 3 and is mainly used to place filling accessories and maintenance tools. It adopts a flip-top structure and a foam board is fixed at the bottom. The foam board is made into a groove according to the outer dimensions of each accessory, which facilitates the classification and unified management of each component.

[0033] In this invention, the simulated compartment 8 is made of 316 stainless steel, while the actual compartment uses an aluminum alloy shell. Under the same operating conditions, this significantly improves the weather resistance and structural strength of the equipment, and extends its service life.

[0034] In this invention, during use, the support vehicle 3 is moved to the training position by controlling the steering lever 6, the parking legs 4 are adjusted to touch the ground, the adjusting wheel 2 is rotated to adjust the adjusting bracket 1, and the simulated compartment 8 is adjusted to be level with the help of the lateral level 13 and the longitudinal level 14. When simulating the refueling training function, the refueling pipeline is connected to the refueling-venting port 20 of the simulated compartment 8 of the training device through a matching special refueling tool, the refueling tool switch is turned on to inject fuel at a pressure of 0.12 MPa; simultaneously, excess gas in the simulated compartment 8 can be discharged through a special venting tool inserted into the vent 12. When simulating the venting training function, the compressed gas pipeline is connected to the vent 12 on the simulated compartment 8 through a special venting tool, the venting tool switch is turned on to inject compressed air at a pressure of 0.2 MPa, and the fuel in the simulated compartment 8 is discharged through the pipeline inserted into the refueling-venting port 20. When simulating air supply and exhaust training, the vent connector is connected to the pressurization port of the simulated compartment 8. On step 15, during the fuel refueling operation, the air supply pipeline continuously injects 0.01 MPa compressed air into the first separator 21 located inside the simulated compartment 8 through the air vent connector. After the first separator 21 expands in volume, it pressurizes the interior of the compartment and discharges internal air bubbles that may be generated during the refueling process due to the irregular structure inside the simulated compartment 8. This process is repeated multiple times until the fuel is full. At this time, the first separator 21 is completely compressed due to the pressure difference and does not occupy internal volume. The air vent connector is connected to the pipeline exhaust port 17 on the simulated compartment 8, and the special oil gun is connected to the accumulator exhaust port 16. The air supply pipeline injects 0.1 MPa compressed air into the second separator 24 inside through the air vent connector from the pipeline exhaust port 17. After the second separator 24 expands in volume, it pressurizes the internal accumulator tank. The internal air is discharged through the accumulator exhaust port 16 and the special oil gun. This process is repeated multiple times until the accumulator tank is full of fuel. At this time, the second separator 24 is completely compressed due to the pressure difference, completing the pipeline air supply and exhaust operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
