Description

Technical Field

[0001] The utility model relates to the field of fire emergency equipment, in particular to a fire motor refueling vehicle. Background Art

[0002] Firefighting mobile refueling trucks, as critical logistical support equipment, play an indispensable role in emergency rescue scenarios such as natural disasters, emergencies, and fires. Designed to quickly and safely refuel various firefighting vehicles, emergency equipment, and temporary facilities, they are capable of swiftly responding and traversing complex environments, ensuring uninterrupted rescue operations. Firefighting mobile refueling trucks not only improve rescue efficiency but also significantly enhance the flexibility and reliability of the emergency response system, playing a vital role in protecting the lives and property of the people.

[0003] Traditional fuel tankers, with their large load capacity and stable transport performance, have long been the mainstay of fuel distribution. However, these vehicles are bulky and complex to operate, making them unsuitable for all rescue scenarios. In particular, in complex terrain such as urban villages, tunnels, mountain roads, and narrow roads, the movement and operation of large tanker trucks are significantly restricted, making it difficult to quickly reach the rescue site. In these areas, refueling is sometimes necessary by transporting fuel in drums. However, drum transport is not only inefficient and slow to refuel, but also carries the risk of fuel leaks. This led to the development of three-wheeled fuel tankers. Their three-wheel design significantly reduces their size and weight, enhancing their ability to navigate extreme environments such as narrow alleyways in urban villages, low-ceiling tunnels, and rugged mountain roads, opening up new avenues for emergency rescue.

[0004] Tricycles are only refueled through oil pipes, which is still inefficient. Moreover, when carrying fuel through areas with poor road conditions, the inevitable potholes will cause the vehicle to shake. When the fuel shakes, it collectively tilts to one side, impacting one side of the fuel tank, causing the overall center of gravity of the tricycle and fuel to shift. The tricycle may overturn, causing serious consequences such as fuel leakage. Utility Model Content

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] Example: A fire-fighting mobile refueling vehicle, such as Figure 1-Figure 3As shown, it includes an electric tricycle 1, a PVC diesel barrel 2, a sealing cover 201, a mounting frame 3, a first refueling pump 4, a first oil pipeline 5, a 10-meter refueling pipe 501, a first hard oil pipe 502, a first refueling gun 6, a strengthening component and a limiting mechanism.

The other end of the oil pipe 5 is connected to the top of the PVC diesel barrel 2 and is connected to the first hard oil pipe 502. The first hard oil pipe 502 is located inside the PVC diesel barrel 2 and extends into the bottom of the PVC diesel barrel 2 to ensure that all the fuel can be extracted. The oil outlet of the first refueling pump 4 is connected to a 10-meter refueling pipe 501. The other end of the 10-meter refueling pipe 501 is connected to a first refueling gun 6. The first refueling gun 6 is placed on the mounting bracket 3. A reinforcement component is also provided on the PVC diesel barrel 2. The reinforcement component is used to add a large amount of fuel. A limiting mechanism for limiting fuel shaking is provided in the PVC diesel barrel 2.

[0022] like Figure 1 and Figure 2 As shown, the reinforcement component includes a second oil pipeline 7, a 5-meter refueling pipe 701, a second hard oil pipe 702, a second refueling pump 8, a second refueling gun 9 and a hook 901. The second refueling pump 8 is installed at the rear end of the electric tricycle 1. The power of the second refueling pump 8 is greater than that of the first refueling pump 4. Specifically, the first refueling pump 4 uses a 24V voltage, while the second refueling pump 8 uses a 220V voltage. One end of the second oil pipeline 7 is connected to the oil inlet of the second refueling pump 8, and the other end of the second oil pipeline 7 is connected to the top of the PVC diesel barrel 2 and is connected to The second hard oil pipe 702 is located in the PVC diesel barrel 2 and extends into the bottom of the PVC diesel barrel 2. The oil outlet of the second refueling pump 8 is connected to a 5-meter refueling pipe 701. The other end of the 5-meter refueling pipe 701 is connected to a second refueling gun 9. The unit flow of the second refueling gun 9 is greater than that of the first refueling gun 6. Specifically, the first refueling gun 6 is a 100-liter refueling gun, and the second refueling gun 9 is a 120-liter refueling gun. A hook 901 is connected to the PVC diesel barrel 2, and the second refueling gun 9 is clamped on the hook 901.

[0023] like Figure 2 and Figure 3As shown, the limiting component includes a guide rod 10, a screw rod 11, a motor 12, a limit plate 13, an exhaust lifting and contraction pipe 14 and a filter sleeve 15. Multiple guide rods 10 are connected to the PVC diesel barrel 2. The motor 12 is installed on the PVC diesel barrel 2. The output shaft of the motor 12 faces downward and is connected to the screw rod 11. The bottom of the screw rod 11 is rotatably connected to the PVC diesel barrel 2. The limit plate 13 is slidably connected to the guide rod 10. The limit plate 13 is threadedly connected to the screw rod 11. The limit plate 13 is slidably connected to the first hard oil pipe 502 and the second hard oil pipe 702. The limit plate 13 is connected to the exhaust lifting and contraction pipe 14. The top of the exhaust lifting and contraction pipe 14 is connected to the filter sleeve 15. The top of the filter sleeve 15 is connected to the upper wall of the PVC diesel barrel 2.

[0024] Under normal circumstances, the sealing cover 201 is opened, the PVC diesel barrel 2 is filled with fuel, and then the PVC diesel barrel 2 is sealed with the sealing cover 201 for fire rescue. When the electric tricycle 1 is needed to transport fuel, the fire truck carries the electric tricycle 1 to the rescue site quickly, and then drives the electric tricycle 1 to transport the fuel. Before transportation, the motor 12 is turned on, and the motor 12 drives the screw rod 11 to rotate, pushing the limit plate 13 to move downward, pushing the limit plate 13 to slide along the guide rod 10 and the hard oil pipe, and finally making the limit plate 13 close to the upper surface of the fuel, so that during transportation, the electric tricycle 1 shakes and the fuel When it shakes, it contacts the limit plate 13, so it will not tilt to one side and maintain the position of the center of gravity. After refueling other equipment, the fuel in the PVC diesel barrel 2 is reduced, and the motor 12 still drives the screw rod 11 to rotate to ensure that the limit plate 13 is in contact with the upper surface of the fuel, limiting the shaking amplitude of the fuel. When the limit plate 13 moves, the exhaust riser 14 stretches, and the air between the fuel and the limit plate 13 is stretched and transported upward through the exhaust riser 14, and finally discharged through the filter sleeve 15. The PVC diesel barrel 2 is provided with an air valve to maintain the air pressure in the PVC diesel barrel 2;

[0025] When refueling other equipment, select a suitable refueling gun according to the amount of fuel to be replenished and the refueling location. If some equipment is far away from the electric tricycle 1 and the electric tricycle 1 cannot get closer, use the refueling gun connected to the 10-meter refueling pipe 501. For example, for a forklift with a large refueling volume, use the 220V second refueling pump 8. During the refueling process, first remove the selected refueling gun. If the first refueling gun 6 is selected, remove it from the mounting bracket 3, pull out the 10-meter refueling pipe 501, insert the first refueling gun 6 into the fuel tank port of the equipment, turn on the first refueling pump 4, and the first refueling pump 4 draws the fuel in the PVC diesel barrel 2 through the first oil pipeline 5 and the first hard oil pipe 502, and completes the refueling process through the 10-meter refueling pipe 501 and the first refueling gun 6. If the second refueling gun 9 is selected, remove the second refueling gun 9 from the hook 901, turn on the second refueling pump 8 to complete the refueling. After refueling is completed, turn off the refueling pump, tidy up the refueling pipe and put the refueling gun back.

[0026] like Figure 1 and Figure 2 As shown, a tool box 16 is also included. The tool box 16 is provided at the bottom of the rear end of the electric tricycle 1.

[0027] The tool box 16 contains basic maintenance tools, such as a wrench for tightening screws, tools for repairing the electric tricycle 1, etc. The driver uses the tools to ensure the transportation process of the fuel.

[0028] like Figure 1 and Figure 2 As shown, it also includes a buckle 17. A plurality of buckles 17 are connected to the PVC diesel barrel 2. The 10-meter refueling pipe 501 and the 5-meter refueling pipe 701 are snapped into the buckle 17.

[0029] The refueling pipe is connected to the PVC diesel barrel 2 through a buckle 17, which is convenient to remove when in use, and the tidying process after refueling is more convenient.

[0030] like Figure 2 As shown, a meter 18 is also included. The mounting frame 3 is mounted with the meter 18 , and the meter 18 is used to measure the oil storage amount of the PVC diesel barrel 2 .

[0031] During the refueling process, the meter 18 can display the amount of fuel added in a single refueling and the amount of fuel remaining in the PVC diesel barrel 2, which helps the driver to determine whether the electric tricycle 1 at the other end needs to be refueled to ensure the smooth progress of the rescue process.

[0032] like Figure 2 As shown, it also includes an electrostatic grounding alarm 19. The electrostatic grounding alarm 19 is installed on the rear side of the PVC diesel barrel 2. When the equipment generates static electricity, the electrostatic grounding alarm 19 can emit an audible and visual alarm and eliminate the generated static electricity at the same time.

[0033] When firefighting and fuel transportation are needed, the fire truck carries an electric tricycle 1 equipped with a PVC diesel barrel 2 to quickly reach the rescue site. After arriving, the electric tricycle 1 is started for transportation, and the motor 12 drives the screw 11 to rotate, causing the limit plate 13 to slide downward along the guide rod 10 and the hard oil pipe until it is close to the upper surface of the fuel, thereby limiting the shaking of the fuel during transportation and maintaining the stability of the vehicle's center of gravity. When the limit plate 13 moves, the exhaust riser 14 is stretched accordingly, and the air between the fuel and the limit plate 13 is discharged through the filter sleeve 15, maintaining the air pressure balance in the PVC diesel barrel 2. After arriving at the refueling location, select the appropriate refueling gun based on the refueling location and refueling amount required. If the distance is far or the refueling amount is large, use the second refueling gun 9 with a longer refueling pipe and a second refueling pump 8; if the distance is close or the refueling amount is moderate, use the first refueling gun 6. When refueling, remove the refueling gun from the mounting bracket 3 or hook 901, pull out the refueling hose of the corresponding length, insert the refueling gun into the fuel tank port of the device to be refueled, turn on the corresponding refueling pump, and the fuel will be transported to the device tank through the oil pipeline, hard oil pipe and refueling hose. During the refueling process, the meter 18 displays the amount of fuel added in a single shot and the amount of fuel remaining in the PVC diesel barrel 2 in real time, helping the driver determine whether to call another electric tricycle 1 for refueling. After refueling is completed, turn off the refueling pump, tidy up the refueling hose and put the refueling gun back in place. At the same time, the basic maintenance tools in the tool box 16 provide the driver with the ability to deal with emergencies, ensuring the smooth progress of the entire fuel transportation and refueling process.
