Description

Technical Field

[0001] The present invention relates to a fixing structure for a high-pressure fluid storage container for trailer loading, and more particularly, to a fixing structure for a high-pressure fluid storage container for trailer loading for safely fixing a container array including a plurality of high-pressure fluid storage containers arranged side by side in the lateral direction, with one or more stacked in the vertical direction, to a trailer.

Background Art

[0002] Conventionally, fossil fuels, which have been utilized as the main energy source, have become a concern for depletion over time, and due to environmental pollution problems, human interest is gradually shifting to other alternative energy sources.

[0003] Among such alternative energy sources, hydrogen fuel has attracted attention. Hydrogen is not only extremely abundant but also has no concerns about environmental pollution and has a very high potential.

[0004] In particular, automobiles using hydrogen fuel are being studied as an alternative to automobiles using existing internal combustion engines, and currently, the results are emerging.

[0005] Therefore, various studies on storage containers that can safely store high-pressure hydrogen gas provided in automobiles, charging stations, etc. are also actively being conducted. In relation to this, continuous research is also being carried out on the fixing structure of trailers for safely transporting such hydrogen gas storage containers.

[0006] However, the conventional fixing structure of trailers for transporting hydrogen gas storage containers is a method of individually fixing each hydrogen gas storage container so that it does not move. Therefore, not only does the loading and unloading process take a long time, but there is also a problem that the transportation cost increases due to additional manual labor.

[0007] Therefore, a method for solving such problems is required.

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

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

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

[0032] The high-pressure fluid storage container fixing structure for trailer loading according to the first embodiment of the present invention can be constructed on a trailer, which is a loading part of a conveying means, in order to fix a container array AR in which one or more are stacked in the vertical direction 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 convenience of explanation.

[0034] As shown in FIGS. 1 to 3, the high-pressure fluid storage container fixing structure for trailer loading 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 a vertical frame and a horizontal frame and is provided along the periphery of the trailer, and a loading space in which the high-pressure fluid storage container 1 is loaded is formed inside.

[0036] The fixed 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 to simultaneously fix the neck portions 2 of each high-pressure fluid storage container 1.

[0037] Also, both ends of the fixed plate 100 can be fastened to a predetermined height of the vertical frame of the main frame 10.

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

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

[0040] In the present embodiment, since the first auxiliary angle 110 and the second auxiliary angle 120 are each formed to have a U-shaped end face, the horizontally formed bottom plate is connected in a direction perpendicular to the fixed plate 100 to provide a reinforcing force.

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

[0042] Pipes (not shown) through which a predetermined fluid utilized in the transportation process of the high-pressure fluid storage container 1 flows can be placed in such first pipe fixing channel 111 and second pipe fixing channel 121.

[0043] At this time, the first pipe fixing channel 111 may have an opening facing upward, and the second pipe fixing channel 121 may have an opening facing downward.

[0044] That is, in the present embodiment, since the front-rear directions of the first pipe fixing channel 111 and the second pipe fixing channel 121 are each hidden by the side plates of the first auxiliary angle 110 and the second auxiliary angle 120, the pipes placed inside the first pipe fixing channel 111 and the second pipe 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 one or more can be fixed to the trailer in the unit of the container array AR stacked in the vertical direction. Therefore, not only can the entire transportation process including loading and unloading be conveniently carried out, but also the overall safety of the working process can be improved.

[0046] In particular, the high-pressure fluid storage container fixing structure for trailer loading of the present invention has the advantage that the manufacturing cost can be reduced because the overall structure is simply formed.

[0047] The above has been described in detail for the present embodiment. Hereinafter, other embodiments of the present invention will be described. In each of the embodiments described below, redundant descriptions of the same components as those in the first embodiment described above will be omitted.

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

[0049] The second embodiment of the present invention shown in FIG. 4 has the feature of similarly including all the components of the first embodiment described above and further including a support unit 200.

[0050] Such a support unit 200 is provided between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part, and plays a role of providing a supporting force.

[0051] Specifically, in the present 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 a support force on the side in the direction where the high-pressure fluid storage container 1 is located, and the second support plate 220 is disposed at a predetermined distance from such a first support plate 210 and provides a support force on the side opposite to the direction where the high-pressure fluid storage container 1 is located with respect to the first support plate 210.

[0053] At this time, 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 lower part, 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 upper part.

[0054] Thereby, in the present embodiment, since the region between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part is completely shielded by the first support plate 210 and the second support plate 220, the pipes installed in the first pipe fixing channel 111 and the second pipe fixing channel 121 inside thereof are not exposed to the outside, and the safety can be further enhanced.

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

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

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

[0058] That is, in the present 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 between the second auxiliary angle 120 and the first support plate 210 and the second support plate 220 from directly contacting each other, being pressurized, and wearing.

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

[0060] The third embodiment of the present invention shown in FIG. 6 includes a support unit 200 provided between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part to provide a supporting force, similar to the aforementioned second embodiment. Such a support unit 200 may include a first support plate 210 and a second support plate 220.

[0061] Further, in the present embodiment, the second support plate 220 has a feature that a part 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 adjacent to the high-pressure fluid storage container 1 side, so it receives a greater load applied from the container array AR.

[0063] That is, the second support plate 220 of the present embodiment can disperse the load applied to the first support plate 210 to form a more stable support structure.

[0064] For this purpose, the second support plate 220 of the present 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 support between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part.

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

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

[0068] Furthermore, in the present 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 support between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part.

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

[0071] Furthermore, the load application portion 213 has a shape that further protrudes from the end portion of the first extension portion 212 toward the second support plate 210 side, 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 side. For this purpose, a step with the first extension portion 212 may be formed at the lower part of the load application portion 213.

[0072] That is, the first support plate 210 and the second support plate 220 may be formed in a shape that meshes with each other, or a structure for dispersing the load may be provided by placing the load application portion 213 on the upper part of the load support portion 223.

[0073] On the one hand, in the present embodiment, since the lower surface of the first support plate 210 connected by the first support portion 211 - the first extension portion 212 - the load application portion 213 and the lower surface of the second support plate 220 connected by the second support portion 221 - the second extension portion 222 - the load support portion 223 are formed in an arch shape at the end surface, strong load resistance can be provided.

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

[0075] The third embodiment of the present invention shown in FIG. 7, similar to the aforementioned second embodiment, includes a support unit 200 provided between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part to provide a supporting force. Such a support unit 200 may include a first support plate 210 and a second support plate 220.

[0076] Furthermore, in the present embodiment, the first support plate 210 and the second support plate 220 are characterized in that they form an auxiliary channel C separately partitioned so that a refrigerant flows between them.

[0077] For this purpose, in the present 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 lower part and the second auxiliary angle 120 of the container array AR located at the upper part.

[0079] Also, the first channel forming portion 214 has a shape protruding from such a first support portion 211 toward the second support plate 220, but is provided in pairs at intervals in the vertical direction.

[0080] Furthermore, in the present 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 support between the first auxiliary angle 110 of the container array AR located at the lower part and the second auxiliary angle 120 of the container array AR located at the upper part.

[0082] In addition, the second channel forming portion 224 has a shape protruding from such a second support portion 221 toward the first support plate 210, and is provided in pairs at intervals in the vertical direction.

[0083] At this time, 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, steps that mesh with each other may be formed at the ends of the first channel forming portion 214 and the second channel forming portion 224.

[0084] As described above, in the present embodiment, the first support plate 210 and the second support plate 220 form an auxiliary channel C in which the refrigerant flows separately between them, so that the fluid flowing in 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 container 1 is loaded can be effectively suppressed.

[0085] As described above, the preferred embodiments according to the present invention have been described. However, in addition to the above-described embodiments, it is obvious to those having ordinary knowledge in the art that the present invention can be embodied in other specific forms without departing from the spirit and scope thereof. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus the present invention is not limited to the above description, and may be modified within the scope of the appended claims and their equivalents.
