Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please refer to the following: Figures 1 to 10 This invention provides a specific embodiment of a mobile hydrogen refueling system. The mobile hydrogen refueling system includes a hydrogen storage component 1, a venting component 2, a driving component 3, and a moving component 4. The hydrogen storage component 1 includes several hydrogen storage cylinders 11, each connected to a hydrogen storage device via an inlet pipe 12 and to a receiving device 8 via an outlet pipe 13. The venting component 2 is located on the outlet pipe 13 and is used to control the venting of hydrogen from the hydrogen storage component 1 according to required operating parameters. The driving component 3 is located on the inlet pipe 12 and is used to drive the movement of hydrogen within the inlet pipe 12. The moving component 4 is connected to the hydrogen storage component 1, the venting component 2, and the driving component 3, and is used to move between the hydrogen storage device and the receiving device 8.

[0057] For ease of explanation, please refer to Figure 1 A rectangular coordinate system is established with any point in space as the origin, the setting direction of the upper mounting frame 41 in the movable component 4 relative to the lower mounting frame 42 as the Z-axis, the setting direction of the handle 44 in the movable component 4 relative to the upper mounting frame 41 as the X-axis, and the straight line direction that is perpendicular to both the X-axis and the Z-axis as the Y-axis. The XY plane is a horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, and the direction indicated by the Z-axis is the vertical direction.

[0058] In this embodiment, the hydrogen storage cylinder 11 is a carbon fiber composite gas cylinder used to store high-pressure hydrogen, for storing external hydrogen and supplying hydrogen to fuel cell drones; the venting component 2 controls the hydrogen flow direction and releases excess gas from the pipeline; the drive component 3 can be one or more portable electric piston hydrogen booster pumps, used to increase the hydrogen pressure from low to high and complete the hydrogen refueling function; the moving component 4 integrates the hydrogen storage component 1 and the drive component 3 together, enabling convenient movement of the entire device.

The inner liner 111 is connected to both the outlet pipe 13 and the inlet pipe 12, and the inner liner 111 is provided with a cavity for storing hydrogen. The reinforcing layer 112 is spirally wound on the inner liner 111, and the reinforcing layer 112 has multiple layers, with the winding directions of adjacent reinforcing layers 112 intersecting. The protective layer 113 is disposed on the side of the reinforcing layer 112 away from the inner liner 111, and is used to provide protection for the reinforcing layer 112.

[0061] In this embodiment, the inner liner 111 is made of aluminum and is wound with carbon fiber. An additional layer of carbon fiber is spirally wound around the outer layer of the inner liner 111, forming two interwoven fiber layers (reinforcing layer 112) in cross-section. A single layer of fiber (protective layer 113) is wound around the reinforcing layer 112, providing protection for the reinforcing layer 112 and preventing the carbon fiber of the reinforcing layer 112 from breaking under impact. This design of the hydrogen storage cylinder 11 reduces the volume of hydrogen storage and, in conjunction with the venting component 2, addresses current problems with hydrogen refueling while further ensuring safety.

By using the opening and closing of different shut-off valves 23, the flow of hydrogen in different pipeline directions can be changed to achieve hydrogen flow direction control, and at the same time, the function of releasing residual gas in the pipeline can be achieved. In use, the temperature sensor transmits the detected temperature information to the controller 24. The controller 24 has pre-set temperature threshold data. The controller 24 determines whether the temperature is within the safe range. When the temperature reaches 110℃±5℃, in order to protect the equipment safety, the bottle mouth valve 21, in conjunction with the shut-off valve 23, discharges hydrogen through the venting pipeline 22, protecting the equipment and personnel safety. Here, anything that can achieve the above-mentioned performance functions of the controller 24, bottle mouth valve 21, and shut-off valve 23 is within the scope of protection of this application.

The hydrogen storage cylinder 11 is fixedly connected to the upper frame 412 by a clamp 5; several hydrogen storage cylinders 11 are symmetrically arranged on both sides of the controller 24.

[0069] The storage and supply method is as follows: hydrogen from the long-tube trailer or the hydrogen production unit in the station is transported to the hydrogen storage component 1 for pressurization from low pressure to high pressure. The drive component 3 can increase the low pressure hydrogen from 3MPa to 14MPa to 35MPa. In addition, the hydrogen in the hydrogen storage cylinder 11 can be balanced from high pressure to low pressure. The drive component 3 can also be used to provide the required gas pressure for the hydrogen cylinder of the UAV.

[0070] For example, please refer to Figure 9 The mobile hydrogen refueling system operates in three modes: storage mode, refueling mode, and pressurization mode. There are five shut-off valves 23, which are designated as K1, K2, K3, K4, and K5, respectively, and the outlet pressure gauge 15 is designated as P2.

[0071] Mode 1: Gas Storage Mode

[0072] As a gas storage device, low-pressure hydrogen gas (3MPa to 15MPa) is introduced into the inlet port 16, pressurized to 35MPa by the drive assembly 3, and stored in two 54L carbon fiber composite high-pressure hydrogen storage cylinders 11. The operation process is as follows: the gas source (3MPa to 15MPa) is connected to the inlet port 16, K2 is opened to balance the pressure between the gas source and the hydrogen storage cylinder 11, K2 is closed after balance, K1 and K3 are opened, the drive assembly 3 is started, and the P2 display instrument (pressure transmission pressure at the outlet of the booster pump) is observed. When the instrument displays 35MPa, the drive assembly 3 is closed, the shut-off valve on the gas source is closed, and then K1 and K3 are closed. At this time, 35MPa hydrogen gas has been stored in the hydrogen storage cylinder 11; K5 is opened to release the gas in the pipeline; the gas storage process is completed.

[0073] Mode 2: Supply Unit

[0074] As a refueling device, it can supply hydrogen gas of not less than 3MPa from the hydrogen storage cylinder 11 to the receiving device 8 for pressurization. The operation process is as follows: Connect the outlet port 17 to the receiving device 8 using a metal hose. Open K3 and K4 to balance the pressure between the hydrogen storage cylinder 11 and the receiving device 8. After balancing, close K3, open K1 and K2, start the drive assembly 3, and observe the P2 display instrument (pressure transmission pressure at the outlet of the booster pump). When the instrument displays 35MPa, close the drive assembly 3, close the shut-off valve on the receiving device 8, and then close K1, K2, and K4. At this point, the receiving device 8 has been pressurized to 35MPa. Open K5 to release the gas in the pipeline; the refueling process is complete.

[0075] Mode 3: Boosting device

[0076] As a pressurization device, it can directly supply hydrogen gas of not less than 3MPa to the receiving device 8 for pressurization. The operation process is as follows: connect the gas source of 3MPa to 15MPa to the inlet port 16, and use a metal hose to connect the outlet port 17 to the receiving device 8; open K1 and K4, and turn on the drive assembly 3. At this time, the entire system will act as a single pressurization device, using the gas source to pressurize the receiving device 8. Observe the P2 display instrument (pressurization pump outlet pressure). When the instrument displays 35MPa, close K1 and K4. Disconnect the connection with the gas source and disconnect the connection with the receiving device 8; open K5 to release the gas in the pipeline; the pressurization process is completed.

[0077] The device replenishes hydrogen from the hydrogen storage cylinder 11 into a small hydrogen cylinder, such as the hydrogen cylinder used in a fuel cell drone. The process is as follows: 1) Close K2 and open K4 to directly fill the drone's cylinder with the high-pressure gas from the hydrogen storage cylinder 11; 2) Close K3 and open K2 to pressurize the remaining gas in the hydrogen storage cylinder 11 to the required pressure of the refueling tank via the drive assembly 3.
