In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or embodiments in a suitable manner.

[0028] Please refer to Figure 1 The embodiment of the utility model provides a kind of mobile hydrogenation station, the mobile hydrogenation station includes hydrogen source 1, pressure reducing valve 5, protection component, solid hydrogen storage bottle 10 and mounting frame 12, wherein:

[0029] In the embodiment, hydrogen source 1 is fixedly arranged on mounting frame 12, and the bottom of mounting frame 12 is provided with movable device, when needed, hydrogen source 1 can be moved by moving mounting frame 12, and in the embodiment, hydrogen source 1 is used to store hydrogen, and then supply the user who needs hydrogen.

[0030] The outlet of hydrogen source 1 is communicated with pressure reducing valve 5 by hydrogen pipeline 2, and at the same time, filter 3 and check valve 4 are connected between hydrogen source 1 and pressure reducing valve 5 by hydrogen pipeline 2.

[0031] In this embodiment, one end of the filter 3 is connected to the outlet of the hydrogen source 1 through the hydrogen pipeline 2, the other end is connected to one end of the check valve 4 through the hydrogen pipeline 2, and the other end of the check valve 4 is connected to one end of the pressure reducing valve 5 through the hydrogen pipeline 2, so that the hydrogen from the hydrogen source 1 can be filtered through the filter 3 and then enter the subsequent use process, and the check valve 4 is used to prevent hydrogen backflow.

[0032] During the hydrogenation process, hydrogen flows out of the hydrogen source, passes through the filter 3 and the check valve 4, enters the pressure reducing valve 5, and then is reduced to a suitable filling pressure. The entire process needs to monitor the flow and pressure of hydrogen in real time to ensure the safety and efficiency of hydrogenation.

[0033] Therefore, the mobile hydrogenation station can be quickly deployed to where it is needed, especially in areas where the initial hydrogen energy infrastructure is not perfect, and can provide hydrogen supply in temporary activities or emergency situations. Compared with fixed hydrogenation stations, the initial investment and operating cost of mobile hydrogenation stations are lower, which is suitable for the initial development stage of the market.

[0034] In addition, the mobile hydrogenation station is equipped with various safety protection devices such as safety valves, shut-off valves and leak detection systems to ensure the safety of the hydrogenation process.

[0035] It should be noted here that the filter 3 in this embodiment is a tee-type filter, and the check valve 4 is a straight-through check valve.

[0036] Further, the other end of the pressure reducing valve 5 is connected to a tee valve 6 through the hydrogen pipeline 2, the first end of the tee valve 6 is connected to the corresponding end of the pressure reducing valve 5, the second end is connected to the protection assembly through the hydrogen pipeline 2, and the third end is connected to the solid hydrogen storage bottle 10 through the hydrogen pipeline 2.

[0037] The main function of the pressure reducing valve 5 is to reduce the high-pressure hydrogen gas from the outlet of the hydrogen source 1 to a safe and usable pressure level. The pressure reducing valve 5 automatically adjusts the pressure through the internal flow channel design and spring adjustment mechanism, ensuring that the outlet pressure is stable at the set value. This automatic adjustment mechanism can reduce energy loss and protect downstream equipment from excessive pressure.

[0038] In this embodiment, the protection assembly includes an active relief valve 7 and a relief valve 8, wherein one end of the active relief valve 7 is connected to the corresponding end of the tee valve 6 through the hydrogen pipeline 2, the other end is connected to one end of the relief valve 8 through the hydrogen pipeline 2, and at the same time, the other end of the relief valve 8 is blocked, so that the active relief valve 7 and the relief valve 8 can be used for pressure relief when needed to protect the entire device.

[0039] The three-way valve 6 is communicated with the solid hydrogen storage bottle 10, and the gas inlet switch valve 9 is communicated with the three-way valve 6 through the hydrogen pipeline 2, and the other end is communicated with the solid hydrogen storage bottle 10 through the hydrogen pipeline 2.

[0040] At the same time, the solid hydrogen storage bottle 10 is provided with a cooling box 11, so that the hydrogen from the hydrogen source 1 can be cooled to form solid hydrogen and stored in the solid hydrogen storage bottle 10 with the help of the cooling box 11.

[0041] The three-way valve 6 in the embodiment has three ports, which can control the flow direction of the fluid, realize the functions of flow splitting, flow combining or switching. In the mobile hydrogen refueling station, the first end of the three-way valve 6 is communicated with the pressure reducing valve 5, the second end is communicated with the protection assembly, and the third end is communicated with the solid hydrogen storage bottle 10. Such design makes the three-way valve 6 can flexibly control the flow direction of hydrogen, which can not only transport hydrogen to the protection assembly to ensure safety, but also directly supply hydrogen to the solid hydrogen storage bottle 10.

[0042] The flexibility of the three-way valve 6 is crucial for the operation of the hydrogen refueling station, because it allows quick adjustment of the flow direction of hydrogen under different operating conditions.

[0043] It should be noted that in actual working conditions, the number of solid hydrogen storage bottles 10 can be set according to demand, and the corresponding gas inlet switch valve 9 and cooling box 11 should also be set in corresponding number, as long as the demand is met, which is not limited by the drawings of the embodiment.

[0044] In addition, in the embodiment, the hydrogen source 1, the filter 3, the check valve 4, the pressure reducing valve 5, the active pressure relief valve 7, the pressure relief valve 8, the solid hydrogen storage bottle 10 and the cooling box 11 are fixedly arranged on the mounting frame 12, so that they can move with the mounting frame 12.

[0045] The working mode of the mobile hydrogen refueling station in the embodiment is as follows:

[0046] Firstly, hydrogen can be output by the hydrogen source 1, then filtered by the filter 3 and stored in the solid hydrogen storage bottle 10, and then the solid hydrogen storage bottle 10 can be used when needed.

[0047] Although the utility model discloses as above, the utility model is not limited to this. Any person skilled in the art, without departing from the utility model concept, can also make several modifications and improvements, which all belong to the protection scope of the utility model, therefore the protection scope of the utility model patent should be limited by the range defined in the claims.
