[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 6 This utility model provides a heavy-duty truck alcohol-hydrogen fuel refueling device, which includes: a transport tank 1, a support frame 2 fixedly installed at the bottom of the transport tank 1, a coaxial oil supply pipe 3 fixedly installed inside the transport tank 1, and a feed pipe 31 connected to the oil supply pipe 3 fixedly installed at the top of the transport tank 1. The lower end of the oil supply pipe 3 abuts against the inner bottom wall of the transport tank 1, and a through hole 32 is opened on the oil supply pipe 3 and located near the inner bottom of the transport tank 1. A discharge pipe 4 that can be connected to the fuel gun is fixedly installed at the bottom of the transport tank 1, and a manual valve 41 is installed on both the discharge pipe 4 and the feed pipe 31. A float 51 slidably connected to the oil supply pipe 3 is installed inside the transport tank 1, and a counterweight 5 is fixedly installed on the float 51. A damping sleeve 52 is fixedly fitted on the counterweight 5 and sleeved on the oil supply pipe 3. The damping sleeve 52 is interference-fitted with the oil supply pipe 3. An exhaust mechanism 6 is installed on the transport tank 1.

[0026] It should be noted that: the transport container 1 in this utility model is transported by a refueling truck to refuel heavy trucks en route. The transport container 1 is supported and elevated by the support frame 2, and fuel is added to the inside of the transport container 1 through the feed pipe 31. When adding fuel to the transport container 1, the exhaust mechanism 6 is opened, and the feed pipe 31 is opened through the manual valve 41 to inject fuel. The fuel enters the oil supply pipe 3 and enters the inside of the transport container 1 through the bottom through hole 32. As fuel is gradually added, the float 51 floats on the fuel and gradually rises along the oil supply pipe 3 until the transport container 1 is full of fuel. The transport container 1 is then transported by the transport vehicle to the heavy truck for refueling. The refueling gun is connected to the discharge pipe 4, and the discharge pipe 4 is opened through the manual valve 41. The heavy truck is refueled using a refueling gun. As the fuel inside the transport container 1 gradually decreases, the float 51, under the weight of the counterweight 5, gradually slides downwards, always in contact with the fuel level. During the subsequent transport of the transport container 1, the float 51 and the counterweight 5 prevent the fuel in the lower space of the transport container 1 from shaking. This utility model, by setting the float 51 and the counterweight 5 inside the transport container 1, ensures that the float 51 is always in contact with the fuel level during fuel transport, effectively preventing the alcohol-hydrogen fuel inside the transport container 1 from shaking, reducing the possibility of static electricity generated by friction between the alcohol-hydrogen fuel and the container wall, reducing the safety risks caused by the shaking of the alcohol-hydrogen fuel, and improving the safety of alcohol-hydrogen fuel transport.

[0027] Among them, the counterweight 5 is cone-shaped, and the horizontal height of the counterweight 5 gradually decreases from its axis to the annular edge. That is, the weight of the counterweight 5 is larger in the middle, which makes the sliding of the float 51 on the oil pipeline 3 more stable.

[0028] Among them, the damping sleeve 52 on the counterweight 5 and the oil pipe 3 are interference fit, which can make the rising or falling process of the float 51 more stable.

[0029] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 The support frame 2 is L-shaped and has mounting holes 21. The support frame 2 supports the transport barrel 1, and the mounting holes 21 are used for bolt connection and fixation between the support frame 2 and the transport vehicle, thereby fixing the transport barrel 1 on the transport vehicle.

[0030] In the embodiments of this utility model, please refer to Figure 5 An annular sealing gasket 53 is fixedly installed between the counterweight 5 and the float 51, and the annular sealing gasket 53 is interference-fitted with the inner wall of the transport barrel 1; the annular sealing gasket 53 fills the gap between the counterweight 5 and the float 51 and the inner wall of the transport barrel 1, so that fuel will not enter the upper space of the counterweight 5 from the gap.

[0031] In the embodiments of this utility model, please refer to Figure 4 A limiting ring 54 is fixedly sleeved on the oil pipeline 3 near the bottom of the transport barrel 1, and the limiting ring 54 is located above the through hole 32; the limiting ring 54 limits the float 51 to prevent the float 51 from descending too far and blocking the through hole 32.

[0032] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 and Figure 6 The exhaust mechanism 6 includes an exhaust pipe 61 fixedly installed on the top of the transport barrel 1, and the bottom end of the exhaust pipe 61 extends into the interior of the transport barrel 1. A slide pipe 62 is slidably connected inside the exhaust pipe 61, and a vent hole 63 is opened on the outer ring wall at the lower end of the slide pipe 62. A rubber sealing plate 64 is fixedly installed at the bottom of the slide pipe 62. A stop block 66 located above the exhaust pipe 61 is also fixedly installed on the slide pipe 62. A threaded cap 65 is installed at the upper end of the slide pipe 62.

[0033] It should be noted that when exhaust is required, the threaded cover 65 is opened to connect the upper space of the transport tank 1 with the external environment, so that fuel can be added to the transport tank 1 and the heavy truck can be refueled. When adding fuel to the transport tank 1, as the fuel gradually increases, the counterweight 5 on the float 51 gradually rises until it touches the rubber sealing plate 64, pushing the slide tube 62 to slide upward in the exhaust pipe 61. By observing whether the slide tube 62 is lifted, it can be known whether the fuel inside the transport tank 1 is full. At the same time, the stop block 66 limits the slide tube 62, so that the slide tube 62 is confined in the exhaust pipe 61.

[0034] The threaded cap 65 is threadedly connected to the slide tube 62, and a dust filter cloth is installed at the top opening of the slide tube 62. The threaded cap 65 can easily and quickly seal or open the upper opening of the slide tube 62. The dust filter cloth filters the air entering the transport barrel 1 to prevent dust and other impurities from entering.

[0035] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 A vertical strip opening 11 is provided on the outer ring wall of the transport barrel 1, and an explosion-proof transparent glass 12 is fixedly embedded in the strip opening 11.

[0036] It should be noted that the state of the fuel inside the transport container 1 can be directly observed through the explosion-proof transparent glass 12 at the strip opening 11, allowing for timely fuel replenishment.

[0037] The working principle of the heavy-duty truck alcohol-hydrogen fuel refueling device provided by this utility model is as follows:

[0038] In this invention, the transport container 1 is transported by a refueling truck to refuel heavy trucks en route. The transport container 1 is supported and elevated by a support frame 2, and fuel is added to the inside of the transport container 1 through the feed pipe 31. When adding fuel to the transport container 1, the threaded cap 65 is unscrewed to open the venting mechanism 6, and the feed pipe 31 is opened through the manual valve 41 to inject fuel. The fuel enters the fuel delivery pipe 3 and enters the transport container 1 through the bottom through hole 32. As fuel is gradually added, the float 51 floats on the fuel and gradually rises along the fuel delivery pipe 3 until the transport container 1 is full. The transport container 1 is then transported by the transport vehicle to the heavy truck for refueling. The refueling gun is connected to the discharge pipe 4, and the discharge pipe is opened through the manual valve 41. 4. Use a refueling gun to refuel the heavy truck; as the fuel inside the transport container 1 gradually decreases, the float 51, under the gravity of the counterweight 5, gradually slides downwards, always in contact with the fuel level. During the subsequent transport of the transport container 1, the float 51 and the counterweight 5 prevent the fuel in the lower space of the transport container 1 from shaking. This utility model, by setting the float 51 and the counterweight 5 inside the transport container 1, ensures that the float 51 is always in contact with the fuel level during fuel transport, effectively preventing the alcohol-hydrogen fuel inside the transport container 1 from shaking, reducing the possibility of static electricity generated by friction between the alcohol-hydrogen fuel and the container wall, reducing the safety risks caused by the shaking of the alcohol-hydrogen fuel, and improving the safety of alcohol-hydrogen fuel transport.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
