The present invention relates to a high-pressure fluid storage container fixing structure for trailer loading, and more specifically, to a high-pressure fluid storage container fixing structure for trailer loading for safely fixing an array of containers including a plurality of high-pressure fluid storage containers arranged in parallel in a horizontal direction and stacked one or more in a vertical direction on a trailer.
Fossil fuels, traditionally used as the primary energy source, are being exhausted over time, and have environmental pollution issues, so human attention is gradually shifting towards alternative energy sources.
Among the alternative energy sources, hydrogen fuel has attracted attention. Hydrogen is not only abundant but also free from environmental pollution concerns, thereby having a high potential.
In particular, researches on vehicles using hydrogen fuel as an alternative to conventional internal combustion engine vehicles are under way, and show promising results.
Accordingly, various studies on storage containers, which are equipped in vehicles and refueling stations to safely store hydrogen gas filled under high pressure are actively being conducted. In connection with the above studies, researches on a fixing structure of trailers for safely transporting hydrogen gas storage containers are also under way.
However, the conventional fixing structure of trailers for transporting hydrogen gas storage containers adopt a method of individually fixing the hydrogen gas storage containers not to move, resulting in prolonged loading and unloading time and increased transportation costs due to additional manpower.
Therefore, there is a demand for methods to address the problems.

In particular, the high-pressure fluid storage container fixing structure for trailer loading according to the present invention can have a simple overall structure, thereby having an advantage of reducing manufacturing costs.
Till now, the first embodiment has been described in detail. Hereinafter, other embodiments of the present invention will be described. In the following description of each embodiment, a repeated description of components that are provided identically to the first embodiment will be omitted.
In the second embodiment of the present invention illustrated in
The support unit 200 plays a role of providing a support force between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
Specifically, in the present embodiment, the support unit 200 may include a first support plate 210 and a second support plate 220.
The first support plate 210 provides a support force from the direction where the high-pressure fluid storage container 1 is located, and the second support plate 220 is spaced apart from the first support plate 210 by a predetermined distance and provides a support force from the opposite direction to the direction where the high-pressure fluid storage container 1 is located with respect to the first support plate 210.
In this case, the lower portions of the first support plate 210 and the second support plate 220 can be coupled to the first auxiliary angle 110 of the array of containers (AR) located at the lower side, and the upper portions of the first support plate 210 and the second support plate 220 can be coupled to the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
Accordingly, in the present embodiment, the region between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side is completely covered by the first support plate 210 and the second support plate 220, so that the pipe installed inside the first pipe fixing channel 111 and the second pipe fixing channel 121 is not exposed to the outside, thereby improving safety.
As shown in
Additionally, on the inside of the second auxiliary angle 120 of the array of containers (AR) located at the upper side, an elastic second cushion member 122 may be provided to be supported by the upper portions of the first support plate 210 and the second support plate 220.
In other words, the present embodiment 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 being directly in contact and pressed or worn out through the first cushion member 112 and the second cushion member 122.
As shown in
Furthermore, in the present embodiment, a portion of the second support plate 220 is in contact with the first support plate 210 to provide supporting force relative to the first support plate 210.
The reason for doing so is that the first support plate 210 is closer to the high-pressure fluid storage container 1, so it receives a larger load from the array of containers (AR).
In other words, the second support plate 220 of the present embodiment can form a more stable support structure by dispersing the load applied to the first support plate 210.
For this purpose, in the present embodiment, the second support plate 220 may include a second support portion 221, a second extension portion 222, and a load support portion 223.
The second support portion 221 is provided to support the space between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
Furthermore, the second extension portion 222 protrudes from the second support portion 221 towards the first support plate 210.
Also, the load support portion 223 protrudes further toward the first support plate 210 from the end of the second extension portion 222, and a step difference may be formed on the upper side with respect to the second extension portion 222.
Moreover, in the present embodiment, the first support plate 210 may include a first support portion 211, a first extension portion 212, and a load applying portion 213.
The first support portion 211 is provided to support the space between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
And the first extension portion 212 protrudes in the direction of the second support plate 220 from the first support portion 211.
Also, the load application portion 213 protrudes further toward the second support plate 220 from the end of the first extension portion 212, and is placed on the upper side of the load support portion 223 of the second support plate 220 to apply a load to the load support portion 223. For this purpose, a step difference may be formed on the lower side of the load application portion 213 with respect to the first extension portion 212.
In other words, the first support plate 210 and the second support plate 220 are formed in an interlocking manner, and the load application portion 213 being seated on the upper side of the load support portion 223 can provide a structure for dispersing the load.
In the present embodiment, the lower surface of the first support plate 210 connected from the first support portion 211 to the first extension portion 212 to the load application portion 213, and the lower surface of the second support plate 220 connected from the second support portion 221 to the second extension portion 222 to the load support portion 223 may be formed in an arched shape in cross-section to provide strong resistance to the load.
As shown in
Additionally, in the present embodiment, the first support plate 210 and the second support plate 220 form an auxiliary channel C which is separately partitioned between the first support plate 210 and the second support plate 220 and through which a refrigerant can flow.
For this purpose, in the present invention, the first support plate 220 may include a first support portion 211 and a first channel forming portion 214.
The first support portion 211 is provided to support the space between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
Furthermore, the first channel forming portion 214 has a shape protruding from the first support portion 211 toward the second support plate 220, and a pair of the first channel forming portions 214 are vertically spaced apart from each other.
Moreover, in the present embodiment, the second support plate 220 may include a second support portion 221 and a second channel forming portion 224.
The second support portion 221 is provided to support the space between the first auxiliary angle 110 of the array of containers (AR) located at the lower side and the second auxiliary angle 120 of the array of containers (AR) located at the upper side.
Furthermore, the second channel forming portion 224 has a shape protruding from the second support portion 221 toward the first support plate 210, and a pair of the second channel forming portions 224 are vertically spaced apart from each other.
In this case, the first channel forming portion 214 and the second channel forming portion 224 have their ends in contact with each other to form an auxiliary channel (C) inside. For this purpose, a step for interlocking may be formed at the ends of the first channel forming portion 214 and the second channel forming portion 224.
As described above, the present embodiment has the auxiliary channel C separately partitioned between the first support plate 210 and the second support plate 220 and allowing the flow of the refrigerant, thereby effectively suppressing the temperature rise of the fluid flowing inside the pipes placed in the first pipe fixing channel 111 and the second pipe fixing channel 121, and the temperature rise in the loading space where the high-pressure fluid storage containers 1 are loaded.
As described above, while desirable embodiments of the present invention have been examined, it is understood by those skilled in the art that the present invention can be embodied in various specific forms without departing from the spirit or scope of the present invention. Therefore, the described embodiments should be considered as illustrative, not restrictive, and accordingly, the present invention can be modified within the scope of the appended claims and the equivalents.
