[0033] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Figure 1 and Figure 2 1 is a diagram showing a fixing structure of a high-pressure fluid storage container for trailer loading according to a first embodiment of the present invention.

[0035] also, Figure 3 1 is a diagram showing a detailed structure of a fixing structure for a high-pressure fluid storage container for trailer loading according to a first embodiment of the present invention.

[0036] The high-pressure fluid storage container fixing structure for trailer loading according to the first embodiment of the present invention can be installed on a trailer as a loading portion of a transport vehicle to fix one or more container arrays AR stacked in a vertical direction in the trailer.

[0037] In this case, the container array AR is a unit including a plurality of high-pressure fluid storage containers 1 arranged side by side in the lateral direction, and is a unit set for convenience of explanation.

[0038] like Figures 1 to 3As shown, the fixing structure of a high-pressure fluid storage container for trailer loading according to the first embodiment of the present invention includes a main frame 10 , a fixing plate 100 , a first auxiliary corner piece 110 and a second auxiliary corner piece 120 .

[0039] The main frame 10 includes a vertical frame and a horizontal frame, is disposed along the periphery of the trailer, and has a loading space formed therein for loading the high-pressure fluid storage container 1 .

[0040] The fixing plate 100 extends along the arrangement direction (ie, the lateral direction) of the plurality of containers 1 included in the container array AR to simultaneously fix the necks 2 of the plurality of high-pressure fluid storage containers 1 .

[0041] In addition, both ends of the fixing plate 100 may be coupled to the vertical frames of the main frame 10 at a predetermined height.

[0042] In other words, the fixing plate 100 plays a role of simultaneously fixing and supporting each of the high-pressure fluid storage containers 1 arranged in one container array AR.

[0043] The first auxiliary corner piece 110 is a component provided at the upper side of the fixing plate 100 along the extension direction of the fixing plate 100 to provide reinforcement, and the second auxiliary corner piece 120 is a component provided at the lower side of the fixing plate 100 along the extension direction of the fixing plate 100 to provide reinforcement.

[0044] In the present embodiment, the first auxiliary corner piece 110 and the second auxiliary corner piece 120 are both formed to have a “⊏”-shaped longitudinal section, in which a bottom plate formed horizontally is vertically connected to the fixing plate 100 to provide a reinforcing force to the fixing plate 100 .

[0045] In case of the present embodiment, the first auxiliary corner piece 110 may have a first pipe fixing channel 111 formed at an inner side, and the second auxiliary corner piece 120 may have a second pipe fixing channel 121 formed at an inner side.

[0046] The first pipe fixing passage 111 and the second pipe fixing passage 121 may accommodate pipes (not shown) through which fluid flows during transportation of the high-pressure fluid storage container 1 .

[0047] In this case, the first pipe fixing passage 111 may be opened upward, and the second pipe fixing passage 121 may be opened downward.

[0048] That is, in this embodiment, the front-to-rear directions of the first pipe fixing channel 111 and the second pipe fixing channel 121 are covered by the side panels of the first auxiliary corner piece 110 and the second auxiliary corner piece 120, thereby ensuring the safety protection of the pipes placed inside the first pipe fixing channel 111 and the second pipe fixing channel 121.

[0049] As described above, the present invention conveniently performs the transportation process including loading and unloading, and improves the overall safety during the working process by fixing a container array AR including multiple high-pressure fluid storage containers 1 arranged side by side in the horizontal direction and one or more container arrays AR stacked in the vertical direction as a unit on a trailer.

[0050] 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.

[0051] So far, the first embodiment has been described in detail. Hereinafter, other embodiments of the present invention will be described. In the description of each of the following embodiments, repeated description of the same components as the first embodiment will be omitted.

[0052] Figure 4 1 is a diagram showing a detailed structure of a fixing structure for a high-pressure fluid storage container for trailer loading according to a second embodiment of the present invention.

[0053] exist Figure 4 In the second embodiment of the present invention, the fixing structure of the high-pressure fluid storage container for trailer loading according to the second embodiment of the present invention includes all the components mentioned in the first embodiment, and further includes a supporting unit 200 .

[0054] The supporting unit 200 plays a role in providing a supporting force between the first auxiliary corner fitting 110 of the container array AR located at the lower side and the second auxiliary corner fitting 120 of the container array AR located at the upper side.

[0055] Specifically, in the present embodiment, the support unit 200 may include a first support plate 210 and a second support plate 220 .

[0056] The first support plate 210 provides support force from the direction of the high-pressure fluid storage container 1, and the second support plate 220 is spaced a predetermined distance from the first support plate 210 and provides support force from the direction opposite to the direction of the high-pressure fluid storage container 1 relative to the first support plate 210.

[0057] In this case, the lower portions of the first support plate 210 and the second support plate 220 may be connected to the first auxiliary corner piece 110 of the container array AR located on the lower side, and the upper portions of the first support plate 210 and the second support plate 220 may be connected to the second auxiliary corner piece 120 of the container array AR located on the upper side.

[0058] Therefore, in this embodiment, the area between the first auxiliary corner piece 110 of the container array AR located on the lower side and the second auxiliary corner piece 120 of the container array AR located on the upper side is completely covered by the first support plate 210 and the second support plate 220, so that the pipes installed inside the first pipe fixing channel 111 and the second pipe fixing channel 121 will not be exposed to the outside, thereby improving safety.

[0059] Figure 5 1 is a diagram showing a support structure between container arrays of a trailer-mounted high-pressure fluid storage container fixing structure according to a second embodiment of the present invention.

[0060] like Figure 5 As shown, an elastic first buffer member 112 may be provided inside the first auxiliary corner piece 110 of the container array AR located at the lower side to support the lower portions of the first support plate 210 and the second support plate 220 .

[0061] In addition, at the inner side of the second auxiliary corner piece 120 of the container array AR located at the upper side, an elastic second buffer member 122 may be provided to be supported by the upper portions of the first and second support plates 210 and 220 .

[0062] In other words, this embodiment can prevent the contact parts between the first auxiliary corner piece 110 and the first support plate 210, the second support plate 220, and the contact parts between the second auxiliary corner piece 120 and the first support plate 210, the second support plate 220 from directly contacting and being compressed or worn through the first buffer member 112 and the second buffer member 122.

[0063] Figure 6 1 is a diagram showing a support structure between container arrays of a trailer-mounted high-pressure fluid storage container fixing structure according to a third embodiment of the present invention.

[0064] like Figure 6 As shown, similar to the aforementioned second embodiment, the third embodiment of the present invention includes a support unit 200 arranged between a first auxiliary corner piece 110 of a container array AR located on the lower side and a second auxiliary corner piece 120 of a container array AR located on the upper side, and the support unit 200 may include a first support plate 210 and a second support plate 220.

[0065] Furthermore, in the present embodiment, a portion of the second support plate 220 contacts the first support plate 210 to provide a supporting force relative to the first support plate 210 .

[0066] The reason for this 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 container array AR.

[0067] In other words, the second support plate 220 of the present embodiment may form a more stable support structure by dispersing the load applied to the first support plate 210 .

[0068] To this end, 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 .

[0069] The second supporting portion 221 is provided to support a space between the first auxiliary corner fitting 110 of the container array AR located at the lower side and the second auxiliary corner fitting 120 of the container array AR located at the upper side.

[0070] In addition, the second extending portion 222 protrudes from the second supporting portion 221 toward the first supporting plate 210 .

[0071] In addition, the load supporting portion 223 further protrudes from the end of the second extending portion 222 toward the first supporting plate 210 , and a step difference may be formed at an upper side with respect to the second extending portion 222 .

[0072] 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 applying portion 213 .

[0073] The first supporting portion 211 is provided to support a space between the first auxiliary corner fitting 110 of the container array AR located at the lower side and the second auxiliary corner fitting 120 of the container array AR located at the upper side.

[0074] In addition, the first extending portion 212 protrudes from the first supporting portion 211 toward a direction of the second supporting plate 220 .

[0075] In addition, the load applying portion 213 further protrudes from the end of the first extending portion 212 toward the second supporting plate 220, and is placed on the upper side of the load supporting portion 223 of the second supporting plate 220 to apply a load to the load supporting portion 223. For this purpose, a step difference may be formed on the lower side of the load applying portion 213 relative to the first extending portion 212.

[0076] In other words, the first support plate 210 and the second support plate 220 are formed in an interlocking manner, and the load applying portion 213 positioned on the upper side of the load supporting portion 223 may provide a structure for dispersing the load.

[0077] In this embodiment, the lower surface of the first support plate 210 connected from the first support portion 211 to the first extension portion 212 and even the load applying 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 and even the load supporting portion 223 can be formed in an arched shape in cross section to provide strong resistance to the load.

[0078] Figure 7 1 is a diagram showing a support structure between container arrays of a trailer-mounted high-pressure fluid storage container fixing structure according to a fourth embodiment of the present invention.

[0079] like Figure 7 As shown, similar to the aforementioned second embodiment, the fourth embodiment of the present invention includes a support unit 200 arranged between a first auxiliary corner piece 110 of a container array AR located on the lower side and a second auxiliary corner piece 120 of a container array AR located on the upper side, and the support unit 200 may include a first support plate 210 and a second support plate 220.

[0080] In addition, in the present embodiment, the first support plate 210 and the second support plate 220 form an auxiliary channel C which is individually partitioned between the first support plate 210 and the second support plate 220 and through which the refrigerant can flow.

[0081] To this end, in the present invention, the first support plate 210 may include a first support portion 211 and a first passage forming portion 214 .

[0082] The first supporting portion 211 is provided to support a space between the first auxiliary corner fitting 110 of the container array AR located at the lower side and the second auxiliary corner fitting 120 of the container array AR located at the upper side.

[0083] In addition, the first passage 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 passage forming portions 214 are spaced apart from each other in the vertical direction.

[0084] Furthermore, in the present embodiment, the second support plate 220 may include a second support portion 221 and a second passage forming portion 224 .

[0085] The second supporting portion 221 is provided to support a space between the first auxiliary corner fitting 110 of the container array AR located at the lower side and the second auxiliary corner fitting 120 of the container array AR located at the upper side.

[0086] In addition, the second passage 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 passage forming portions 224 are spaced apart from each other in the vertical direction.

[0087] In this case, ends of the first and second passage forming portions 214 and 224 contact each other to internally form the auxiliary passage C. To this end, steps for interlocking may be formed at ends of the first and second passage forming portions 214 and 224 .

[0088] As described above, the present embodiment has an auxiliary channel C that is independently separated between the first support plate 210 and the second support plate 220 and allows the flow of 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 of the loading space loaded with the high-pressure fluid storage container 1.

[0089] As described above, although the desired embodiments of the present invention have been reviewed, it will be appreciated by those skilled in the art that the present invention may be implemented in various specific forms without departing from the spirit or scope of the present invention. Therefore, the described embodiments should be considered illustrative rather than restrictive, and accordingly, the present invention may be modified within the scope of the appended claims and equivalents.
