[0044] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0045] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0046] Please also read Figure 1 and Figure 2 , first direction, the embodiment of the present application discloses a hydrogen storage system 2 protection assembly 1, including a base plate 11, two mounting plates 12, a skeleton beam 13, a protection plate 14 and a side plate 15. The two mounting plates 12 are arranged along the first direction (such as Figure 1 The two ends of the frame beam 13 are respectively connected to the ends of the two mounting plates 12 away from the base plate 11. The protection plate 14 is installed on the frame beam 13. The side plate 15 is arranged in a second direction (as shown in the X direction). Figure 1 The second direction is perpendicular to the first direction. The side panels 15, the protective panels 14, the mounting plate 12 and the base plate 11 form an installation space for installing the hydrogen storage system 2.

[0047] It should be noted that the hydrogen storage system 2 of the embodiment of the present application can be mainly composed of hydrogen storage bottles, or other storage devices, which is not limited here. In addition, the protection component 1 of the hydrogen storage system 2 can be installed on a rail vehicle, or other vehicles, which is not limited here.

[0048] The first direction and the second direction are both parallel to the substrate 11 .

[0049] The mounting plate 12 can be perpendicular to the substrate 11 or can be inclined relative to the substrate 11, which is not limited here. The interval between the two mounting plates 12 in the first direction is the size of the mounting space in the first direction, that is, the two mounting plates 12 in the first direction define the size of the mounting space in the first direction.

[0050] Both ends of the skeleton beam 13 are respectively connected to the two mounting plates 12 , providing a stable mounting frame for the protection plate 14 , thereby providing support for the protection plate 14 and improving the stability of the protection assembly 1 .

[0051] The side plates 15 are arranged on both sides of the protective plate 14 in the second direction, thereby limiting the size of the installation space in the second direction. The side plates 15 are connected to the protective plate 14 and the base plate 11, thereby substantially closing the installation space, thereby protecting the hydrogen storage system 2 arranged in the installation space, preventing the hydrogen storage system 2 from being hit and damaged by foreign objects such as stones, thereby providing a safe and stable operating environment for the hydrogen storage system 2.

[0052] In addition, the protective plate 14 can be set on the side surface of the skeleton beam 13 away from the substrate 11, or on the side surface of the skeleton beam 13 close to the substrate 11, or in the middle position between the side surface of the skeleton beam 13 away from the substrate 11 and the side surface close to the substrate 11.

[0053] Please continue reading Figure 1 and Figure 2 In some embodiments, the skeleton beam 13 includes a first beam body 131, a second beam body 132, and a third beam body 133 connected in sequence. One end of the first beam body 131 away from the second beam body 132 and one end of the third beam body 133 away from the second beam body 132 are respectively connected to the ends of the two mounting plates 12 away from the substrate 11. The second beam body 132 is in the third direction (such as Figure 2 The second beam body 132 is spaced apart from the substrate 11 in the direction (shown in the Z direction), and the spacing between the second beam body 132 and the substrate 11 is greater than the height of the mounting plate 12. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0054] It should be noted that the interval between the second beam 132 and the substrate 11 refers to the minimum distance between the second beam 132 and the substrate 11 in the third direction, and the height of the mounting plate 12 refers to the maximum dimension of the mounting plate 12 in the third direction.

[0055] Among them, the height of the mounting plate 12 refers to the size of the mounting plate 12 in the third direction. It should be noted that the height of the mounting plate 12 can be equal to or greater than the diameter of the hydrogen storage bottle, so that at least one row of hydrogen storage bottles can be arranged between the two mounting plates 12 along the first direction. In addition, the difference between the spacing between the second beam body 132 and the substrate 11 in the third direction and the height of the mounting plate 12 can be equal to or greater than the diameter of the hydrogen storage bottle, so that at least one row of hydrogen storage bottles can be arranged in the third direction and between the second beam body 132 and the mounting plate 12 along the first direction. The spacing between the second beam body 132 and the substrate 11 is greater than the height of the mounting plate 12, which increases the hierarchical nature of the installation space in the third direction, and can increase the volume of the installation space, so as to facilitate the arrangement of more hydrogen storage bottles to form a larger hydrogen storage system 2.

[0056] In some other embodiments, the interval between the second beam 132 and the base plate 11 may be equal to the height of the mounting plate 12 .

[0057] Please continue reading Figure 1 and Figure 2 In some embodiments, the second beam 132 extends along the first direction.

[0058] Among them, the second beam body 132 extends along the first direction, that is, the second beam body 132 is a flat plate structure parallel to the substrate 11, which enhances the rigidity of the second beam body 132 in the first direction, thereby improving the rigidity of the skeleton beam 13 in the first direction and preventing the skeleton beam 13 from deforming in the first direction.

[0059] In some other embodiments, the second beam 132 may also be an arc-shaped structure.

[0060] Please continue reading Figure 1 and Figure 2 In some embodiments, the second beam 132 is located between the two mounting plates 12 in the first direction.

[0061] The second beam body 132 is located between the two mounting plates 12 in the first direction, that is, the size of the second beam body 132 in the first direction is smaller than the interval between the two mounting plates 12 in the first direction, so that the size of the two mounting plates 12 in the first direction is the maximum size of the installation space in the first direction, so that the number of hydrogen storage bottles in the third direction and located between the second beam body 132 and the mounting plates 12 is less than the number of gas storage bottles 21 located between the two mounting plates 12, so as to improve the stability of the installation of the gas storage bottles 21.

[0062] In some other embodiments, the dimension of the second beam 132 in the first direction is equal to the interval between the two mounting plates 12 in the first direction.

[0063] Please continue reading Figure 1 and Figure 2 In some embodiments, the extension direction of the first beam 131 and the extension direction of the third beam 133 are both inclined relative to the first direction and the third direction.

[0064] The extension direction of the first beam 131 and the extension direction of the third beam 133 are both inclined relative to the first direction and the third direction, that is, the first beam 131 and the third beam 133 are also flat plate structures. The first beam 131 and the third beam 133 are both inclined relative to the first direction and the third direction, so that the size of the two mounting plates 12 in the first direction is the maximum size of the mounting space in the first direction, so that the number of hydrogen storage bottles located between the third beam 133 and the mounting plate 12 in the third direction is less than the number of gas storage bottles 21 located between the two mounting plates 12, so as to improve the stability of the installation of the gas storage bottles 21.

[0065] In some other embodiments, the first beam body 131 and the second beam body 132 may be arc-shaped structures.

[0066] Please continue reading Figure 1 In some embodiments, the number of the skeleton beams 13 is at least two, and at least two skeleton beams 13 are arranged at intervals from each other along the second direction.

[0067] At least two spaced-apart skeleton beams 13 are arranged in the second direction, so that the protective plate 14 is carried by at least two skeleton beams 13, thereby improving the stability of the skeleton beams 13 carrying the protective plate 14 and preventing the weight of the protective component 1 from being too heavy.

[0068] In some other embodiments, the number of the skeleton beam 13 may be one.

[0069] See also Figure 3 In some embodiments, the protective plate 14 is connected to the skeleton beam 13 by bolts (not shown in the figure), and the protective plate 14 and the skeleton beam 13 are connected by an anti-departure chain 16, and the side plate 15 and the protective plate 14 are connected by an anti-departure chain 16.

[0070] The anti-drop chain 16 may be a rope or a metal chain, which is not limited here.

[0071] The protective plate 14 is connected to the skeleton beam 13 via an anti-detachment chain 16, which can provide additional connection protection between the protective plate 14 and the skeleton beam 13, prevent the protective plate 14 from being separated from the skeleton beam 13 after the bolts are accidentally loosened or fall off, and prevent the protective plate 14 from falling off and causing accidents.

[0072] Similarly, the side panels 15 and the protective panel 14 are connected via the anti-detachment chain 16 , which can provide a connection guarantee between the side panels 15 and the protective panel 14 and prevent the side panels 15 from detaching from the protective panel 14 .

[0073] In some other embodiments, the protection plate 14 may also be clamped on the skeleton beam 13 .

[0074] Please also read Figure 3 and Figure 4 In some embodiments, the protective plate 14 and the side plate 15 are both provided with a hydrogen exhaust port 17 .

[0075] The protection plate 14 and the side plate 15 are provided with a hydrogen discharge port 17, which can prevent the side plate 15, the protection plate 14, the mounting plate 12 and the base plate 11 from forming a completely closed mounting space, so that after an accidental hydrogen leakage occurs in the hydrogen storage system 2, the leaked hydrogen can be discharged out of the mounting space through the hydrogen discharge port 17, thereby preventing the leaked hydrogen from being in the mounting space, causing the hydrogen concentration in the mounting space to be too high and causing an accident.

[0076] In some other embodiments, a hydrogen exhaust port 17 may be provided on the substrate 11 .

[0077] In some more specific embodiments, a plurality of hydrogen discharge ports 17 may be arranged in rows and columns on the side plate 15. Specifically, each row may include 4 to 6 hydrogen discharge ports 17, and 20 to 22 columns of hydrogen discharge ports 17 may be arranged on the side plate 15. Of course, the number of hydrogen discharge ports 17 in each row and the number of columns of hydrogen discharge ports 17 may be other numbers, which are not limited here.

[0078] Please continue reading Figure 4 In some embodiments, the side panel 15 is provided with an observation port 18 .

[0079] Among them, the observation port 18 is arranged on the side panel 15 near the valve of the hydrogen storage bottle, which can facilitate the staff to check the working status of the valve of the hydrogen storage bottle, or the staff can directly operate the valve of the hydrogen storage bottle through the observation port 18.

[0080] In some other embodiments, the side panel 15 may be provided with a rotatable operating door, which is opened when observation or operation is required.

[0081] In a second aspect, an embodiment of the present application further discloses a rail vehicle (not shown in the figure), comprising the above-mentioned hydrogen storage system 2 protection component 1.

[0082] The rail vehicle in this embodiment is connected to the protective plate 14 and the base plate 11 through the side panel 15, thereby roughly closing the installation space, thereby protecting the hydrogen storage system 2 arranged in the installation space, and preventing the hydrogen storage system 2 from being hit and damaged by foreign objects such as stones during the movement of the rail vehicle, thereby providing a safe and stable operating environment for the hydrogen storage system 2.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
