Description

[Technical Field]

[0001] The present invention relates to a trailer-mounted high-pressure fluid storage container fixing structure, and more particularly to a trailer-mounted high-pressure fluid storage container fixing structure for safely fixing an array of containers to a trailer, the array including multiple high-pressure fluid storage containers arranged side by side in the horizontal direction, with one or more containers stacked vertically. [Background technology]

[0002] Fossil fuels, which have traditionally been used as the main energy source, are expected to run out over time, and due to environmental pollution issues, human interest is gradually shifting to alternative energy sources.

[0003] Among these alternative energy sources, hydrogen fuel is attracting attention. Hydrogen is not only extremely abundant, but also poses no environmental pollution concerns, and has great potential.

[0004] In particular, hydrogen-fueled automobiles have been researched as an alternative to existing automobiles using internal combustion engines, and the results are now beginning to appear.

[0005] For this reason, various researches are being actively conducted on storage containers that can be installed in automobiles and charging stations and can safely store hydrogen gas filled at high pressure. In connection with this, research is also being continuously conducted on trailer fixing structures for safely transporting such hydrogen gas storage containers.

[0006] However, conventional trailer fixing structures for transporting hydrogen gas storage containers require each hydrogen gas storage container to be individually fixed so that it does not move, which not only makes the loading and unloading process take a long time but also requires additional manpower, increasing transportation costs.

[0007] Therefore, a solution to this problem is needed. [Prior art documents] [Patent documents]

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0030] 1 and 2 are diagrams showing the state of a trailer-mounted high-pressure fluid storage container fixing structure according to a first embodiment of the present invention.

[0031] FIG. 3 is a diagram showing a detailed structure of the trailer-mounted high-pressure fluid storage container fixing structure according to the first embodiment of the present invention.

[0032] The trailer-mounted high-pressure fluid storage container fixing structure according to the first embodiment of the present invention can be constructed on a trailer, which is the loading section of a transportation means, in order to fix one or more container arrays AR stacked vertically to the trailer.

[0033] Here, the container array AR is a unit including a plurality of high-pressure fluid storage containers 1 arranged side by side in the horizontal direction, and is a unit set for the convenience of explanation.

[0034] As shown in FIGS. 1 to 3, the trailer-mounted high-pressure fluid storage container fixing structure according to the first embodiment of the present invention includes a main frame 10, a fixing plate 100, a first auxiliary angle 110, and a second auxiliary angle 120.

[0035] The main frame 10 includes vertical and horizontal frames and is provided along the periphery of the trailer, and defines a loading space inside in which the high-pressure fluid storage container 1 is loaded.

[0036] The fixing plate 100 extends in the arrangement direction of the plurality of high-pressure fluid storage containers 1 included in the container array AR, that is, in the horizontal direction, and is provided so as to simultaneously fix the neck portions 2 of the high-pressure fluid storage containers 1.

[0037] In addition, both ends of the fixing plate 100 can be fastened to the vertical frame of the main frame 10 at a predetermined height.

[0038] That is, the fixing plate 100 serves to simultaneously fix and support each of the high-pressure fluid storage containers 1 arranged in one container array AR.

[0039] The first auxiliary angle 110 is a component provided at the upper end of the fixing plate 100 along the extension direction of the fixing plate 100 to provide reinforcing force, and the second auxiliary angle 120 is a component provided at the lower end of the fixing plate 100 along the extension direction of the fixing plate 100 to provide reinforcing force.

[0040] In this embodiment, the first auxiliary angle 110 and the second auxiliary angle 120 are each formed to have a U-shaped end surface, so that the horizontally formed bottom plate is connected to the fixing plate 100 in a vertical direction, thereby providing reinforcing force.

[0041] In particular, in this embodiment, a first piping fixing channel 111 may be formed inside the first auxiliary angle 110, and a second piping fixing channel 121 may be formed inside the second auxiliary angle 120.

[0042] In the first piping fixing channel 111 and the second piping fixing channel 121, a piping (not shown) through which a predetermined fluid flows, which is used in the transport process of the high-pressure fluid storage container 1, can be placed.

[0043] In this case, the first piping fixing channel 111 may have a shape that opens upward, and the second piping fixing channel 121 may have a shape that opens downward.

[0044] In other words, in this embodiment, the front and rear directions of the first piping fixing channel 111 and the second piping fixing channel 121 are hidden by the side plates of the first auxiliary angle 110 and the second auxiliary angle 120, respectively, so that the piping placed inside the first piping fixing channel 111 and the second piping fixing channel 121 can be safely protected.

[0045] In this way, the present invention includes a plurality of high-pressure fluid storage containers 1 arranged side by side in the horizontal direction, and can be fixed to a trailer in container arrays AR, with one or more containers stacked vertically, which not only makes the entire transportation process, including loading and unloading, more convenient, but also improves the overall safety of the work process.

[0046] In particular, the trailer-mounted high-pressure fluid storage container fixing structure of the present invention has an advantage that the overall structure is simple, thereby reducing manufacturing costs.

[0047] This embodiment has been described in detail above, but other embodiments of the present invention will be described below. In each of the embodiments described below, duplicated descriptions of components that are the same as those in the first embodiment will be omitted.

[0048] FIG. 4 is a diagram showing a detailed structure of a trailer-mounted high-pressure fluid storage container fixing structure according to a second embodiment of the present invention.

[0049] The second embodiment of the present invention shown in FIG. 4 includes all of the same components as the first embodiment described above, with the additional feature of including a support unit 200.

[0050] The support unit 200 is provided between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top, and serves to provide a supporting force.

[0051] Specifically, in this embodiment, the support unit 200 may include a first support plate 210 and a second support plate 220 .

[0052] The first support plate 210 provides support on the side in the direction in which the high-pressure fluid storage container 1 is located, and the second support plate 220 is positioned a predetermined distance away from the first support plate 210 and provides support on the opposite side of the first support plate 210 from the direction in which the high-pressure fluid storage container 1 is located.

[0053] In this case, the lower ends of the first support plate 210 and the second support plate 220 may be fastened to the first auxiliary angle 110 of the container array AR located at the bottom, and the upper ends of the first support plate 210 and the second support plate 220 may be fastened to the second auxiliary angle 120 of the container array AR located at the top.

[0054] As a result, in this embodiment, the area between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top is completely shielded by the first support plate 210 and the second support plate 220, so that the piping installed in the first piping fixing channel 111 and the second piping fixing channel 121 inside are not exposed to the outside, thereby increasing safety.

[0055] FIG. 5 is a diagram showing a support structure between container arrays in a fixed structure of a trailer-mounted high-pressure fluid storage container according to a second embodiment of the present invention.

[0056] As shown in FIG. 5, a first buffer member 112 made of an elastic material may be provided inside the first auxiliary angle 110 of the container array AR located at the bottom to support the lower ends of the first support plate 210 and the second support plate 220.

[0057] In addition, a second buffer member 122 made of an elastic material may be provided inside the second auxiliary angle 120 of the upper container array AR, supported by the upper ends of the first and second support plates 210 and 220.

[0058] In other words, in this embodiment, the first buffer member 112 and the second buffer member 122 can prevent the contact portions between the first auxiliary angle 110 and the first support plate 210 and the second support plate 220, and the contact portions between the second auxiliary angle 120 and the first support plate 210 and the second support plate 220, from coming into direct contact with each other, being pressurized, and becoming worn.

[0059] FIG. 6 is a diagram showing a support structure between container arrays in a fixed structure of a trailer-mounted high-pressure fluid storage container according to a third embodiment of the present invention.

[0060] The third embodiment of the present invention shown in Figure 6, like the second embodiment described above, includes a support unit 200 that is arranged between a first auxiliary angle 110 of a container array AR located at the bottom and a second auxiliary angle 120 of a container array AR located at the top to provide support, and such support unit 200 may include a first support plate 210 and a second support plate 220.

[0061] In addition, in this embodiment, the second support plate 220 has a feature that a portion thereof contacts the first support plate 210 and provides a supporting force to the first support plate 210 .

[0062] This is because the first support plate 210 is provided closer to the high-pressure fluid storage container 1 and is therefore subjected to a larger load from the container array AR.

[0063] That is, the second support plate 220 of this embodiment distributes the load applied to the first support plate 210, thereby forming a more stable support structure.

[0064] For this purpose, the second support plate 220 of this embodiment may include a second support portion 221 , a second extension portion 222 , and a load support portion 223 .

[0065] The second support portion 221 is provided to provide support between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top.

[0066] The second extension portion 222 has a shape that protrudes from the second support portion 221 in the direction of the first support plate 210.

[0067] Furthermore, the load support portion 223 has a shape that protrudes further from the end of the second extension portion 222 toward the first support plate 210 side, and a step may be formed between the load support portion 223 and the second extension portion 222 at its upper portion.

[0068] Furthermore, in this embodiment, the first support plate 210 may include a first support portion 211 , a first extension portion 212 , and a load application portion 213 .

[0069] The first support portion 211 is provided to provide support between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top.

[0070] The first extension portion 212 has a shape that protrudes from the first support portion 211 in the direction of the second support plate 220.

[0071] Furthermore, the load application portion 213 has a shape that protrudes further from the end of the first extension portion 212 toward the second support plate 210, and is placed on the upper part of the load support portion 223 of the second support plate 220 to apply a load to the load support portion 223. For this reason, a step may be formed between the lower part of the load application portion 213 and the first extension portion 212.

[0072] That is, the first support plate 210 and the second support plate 220 may be formed in a shape that interlocks with each other, or the load application portion 213 may be placed on top of the load support portion 223 to provide a structure that distributes the load.

[0073] Meanwhile, in this embodiment, the lower surface of the first support plate 210, which is connected by the first support portion 211, the first extension portion 212, and the load application portion 213, and the lower surface of the second support plate 220, which is connected by the second support portion 221, the second extension portion 222, and the load support portion 223, are formed in an arch shape at the end surfaces, thereby providing strong load resistance.

[0074] FIG. 7 is a diagram showing a support structure between container arrays in a trailer-mounted high-pressure fluid storage container fixing structure according to a fourth embodiment of the present invention.

[0075] The third embodiment of the present invention shown in Figure 7, like the second embodiment described above, includes a support unit 200 that is arranged between a first auxiliary angle 110 of a container array AR located at the bottom and a second auxiliary angle 120 of a container array AR located at the top to provide support, and such support unit 200 may include a first support plate 210 and a second support plate 220.

[0076] Furthermore, in this embodiment, the first support plate 210 and the second support plate 220 are characterized by forming a separately partitioned auxiliary channel C between them so that the coolant can flow therethrough.

[0077] For this purpose, in this embodiment, the first support plate 220 may include a first support portion 211 and a first channel forming portion 214 .

[0078] The first support portion 211 is provided to support between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top.

[0079] The first channel forming portions 214 are shaped to protrude from the first support portion 211 toward the second support plate 220, and are provided in pairs spaced apart from each other in the vertical direction.

[0080] Furthermore, in this embodiment, the second support plate 220 may include a second support portion 221 and a second channel forming portion 224 .

[0081] The second support portion 221 is provided to provide support between the first auxiliary angle 110 of the container array AR located at the bottom and the second auxiliary angle 120 of the container array AR located at the top.

[0082] The second channel forming portions 224 are shaped to protrude from the second support portion 221 toward the first support plate 210, and are provided in pairs spaced apart from each other in the vertical direction.

[0083] At this time, the first channel forming portion 214 and the second channel forming portion 224 come into contact with each other at their ends to form an auxiliary channel C therebetween. For this purpose, steps may be formed at the ends of the first channel forming portion 214 and the second channel forming portion 224 to engage with each other.

[0084] In this manner, in this embodiment, the first support plate 210 and the second support plate 220 are separately partitioned between each other to form an auxiliary channel C through which the refrigerant flows, thereby effectively suppressing the temperature rise of the fluid flowing through the piping placed in the first piping fixing channel 111 and the second piping fixing channel 121 and the temperature rise in the loading space in which the high-pressure fluid storage container 1 is loaded.

[0085] Although the preferred embodiments of the present invention have been described above, it will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the present invention. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
