Description

{Supporting device for high-pressure fluid storage container}

The present invention relates to a support device for a high-pressure fluid storage vessel, and more specifically, to a support device for a high-pressure fluid storage vessel which, when loading an end box to form a manifold, prevents damage to the fastening portion by providing the fastening portion inside the end box, and enables the end box to be loaded safely.

Fossil fuels, which were previously used as the main energy source, are increasingly being depleted, and due to environmental pollution issues, human interest is gradually shifting to other alternative energy sources.

Among these alternative energy sources, hydrogen fuel is attracting attention. Hydrogen is not only very abundant, but also has no concerns about environmental pollution, so its potential is very high.

In particular, hydrogen fuel cell vehicles are being studied as an alternative to conventional internal combustion engine vehicles, and the results are currently being seen.

Accordingly, various studies are actively being conducted on storage containers that can be installed in automobiles and charging stations to safely store hydrogen gas filled at high pressure, and research is also continuously being conducted on fixing devices to safely transport containers storing such hydrogen gas.

As an example of this, prior art documents disclose a hydrogen tank support device that prevents deformation of the support device due to the load of the hydrogen tank by inserting and supporting the hydrogen tank in a frame. However, since it is in the form of wrapping around the body of the hydrogen tank, there is a limitation in that the support device takes up a large volume.

Therefore, the need for development of a support device for a high-pressure fluid storage vessel to solve such problems is increasing.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

A support device for a high-pressure fluid storage vessel according to one embodiment of the present invention includes a high-pressure fluid storage vessel (100), an end box (200), and a fastening member (300).

First, the high-pressure fluid storage tank (100) may be a tank that stores high-pressure gas such as hydrogen, LNG, LN ₂ , CNG, etc., and among these, hydrogen may be preferably stored.

Next, the end box (200) can be formed to be coupled to one side of the high-pressure fluid storage container (100) and surround the neck of the high-pressure fluid storage container (100).

The above end box (200) is intended to support one side of the high-pressure fluid storage tank (100), and its overall shape can be formed in a box shape.

At this time, the end box (200) may include a frame portion (210) and a plate portion (220).

The above frame portion (210) may be configured to be located at the outermost portion of the end box (200), and may form a space surrounding the neck portion of the high-pressure fluid storage container (100) and provide the overall shape of the end box (200). Here, the shape of the end box (200) may be a box shape as described above.

Additionally, the frame portion (210) may have a shape in which both longitudinal sides are open.

In addition, the plate portion (220) is provided on the frame portion (210), and at this time, it can be formed in a square shape along the frame portion (210) so that it can be stably provided on the frame portion (210).

At this time, the plate portion (220) may be provided at the center of the length direction of the frame portion (210), but is not necessarily fixed at this position, and may be fixed so as to be able to move along the length direction within a certain range by a sliding portion (not shown in the drawing) to be described later.

Additionally, the plate portion (220) may include a through hole (230) formed in the center so that the neck portion of the high-pressure fluid storage container (100) passes through it.

Accordingly, the high-pressure fluid storage container (100) can be more stably supported on the end box (200) because the neck portion is inserted and fixed into the through hole (230) and supported by the plate portion (220).

In addition, the end box (200) may further include a sliding part (not shown in the drawing), and the sliding part may be provided at a position where the plate part (220) and the frame part (210) are connected so that the plate part (220) can slide along the longitudinal direction of the frame part (210).

Accordingly, when the high-pressure fluid storage vessel (100) expands or contracts due to the high-pressure gas stored therein or is shaken by an external impact, the plate portion (220) can be moved along the longitudinal direction of the frame portion (210) to respond to the change and be stably connected.

Next, the end box (200) may include a groove (211) formed so that the fastening part (300) is provided within the space formed by the end box (200). The details of the fastening part (300) will be described later.

At this time, the home portion (211) may include a first home portion (211a) formed on one surface of the frame portion (210) and a second home portion (211b) formed on the other surface of the frame portion (210).

At this time, the shapes of the first groove portion (211a) and the second groove portion (211b) may be the same as the first groove portion (211a) and the second groove portion (211b), and the first groove portion (211a) and the second groove portion (211b) may be distinguished according to the position where they are formed on the upper or lower surface of the frame portion (210).

In addition, since the frame portion (210) can be formed in a vertically symmetrical shape, the first groove portion (211a) and the second groove portion (211b) can be distinguished based on the time at which the high-pressure fluid storage tank (100) is loaded.

In addition, the first groove portion (211a) and the second groove portion (211b) may be formed by opening a portion of the facing surface of the frame portion (210).

At this time, the width of the first groove portion (211a) and the second groove portion (211b) can be formed to correspond to the diameter of the neck portion of the high-pressure fluid storage container (100).

In addition, the length of the first groove portion (211a) and the second groove portion (211b) can be formed to correspond to a length that the high-pressure fluid storage container (100) does not reach when the end box (200) is connected to one end of the high-pressure fluid storage container (100).

As the width and length of the first groove portion (211a) and the second groove portion (211b) are formed in this manner, when the high-pressure fluid storage container (100) is coupled to the end box (200), the fastening portion (300) is prevented from protruding out of the end box (200), thereby preventing the fastening portion (300) from being damaged by an external force.

In addition, by preventing damage to the fastening portion (300), the phenomenon of the high-pressure fluid storage container (100) being separated or detached from the end box (200) can be prevented.

At this time, when two or more of the high-pressure fluid storage containers (100) are loaded, the end boxes (200) may also be provided in multiple units so that they can be respectively connected to the ends of the multiple high-pressure fluid storage containers (100).

In addition, when two or more of the high-pressure fluid storage containers (100) are loaded, the end boxes (200) can be loaded in the radial direction of the plurality of high-pressure fluid storage containers (100) so that the second groove (211b) of the end box (200) provided at the upper portion and the first groove (211a) of the end box (200) provided at the lower portion are in contact.

Accordingly, the home portion (211) provides a guideline so that the high-pressure fluid storage container (100) and the end box (200) can be loaded in an accurate position when loaded in the radial direction of the plurality of high-pressure fluid storage containers (100), thereby enabling them to be loaded in an accurate position more efficiently than when loaded based only on the side of the end box (200).

Next, the above-mentioned fastening portion (300) can connect the plurality of high-pressure fluid storage containers (100) without protruding outside the end box (200) by the above-mentioned groove portion (211).

At this time, the connecting member (300) may include a connecting member (310) connecting the plurality of high-pressure fluid storage containers (100) and a bracket member (320) that is connected at both ends to the end box (200) to secure the connecting member (310) so that it is provided in the groove (211).

At this time, the connecting member (310) can be formed in a tube shape and can be used to connect the high-pressure fluid storage containers (100) to form a manifold.

In addition, the bracket member (320) may be provided at a position such that the groove portion (211) is not exposed to the outside as shown in FIGS. 3 and 4, and both ends of the bracket member (320) may be fixed to the frame portion (210).

Accordingly, the bracket member (320) can be provided at every location where the groove portion (211) is formed, and the phenomenon of the connecting member (310) provided in the groove portion (211) being bounced off when damaged can be prevented, thereby preventing additional accidents caused by the damaged connecting member (310).

In addition, compared to the case where the connecting member (310) is exposed to the outside of the end box (200) as in the conventional fastening method, the space occupied by the connecting member (310) can be reduced, and the connecting member (310) can be provided by utilizing the space that was previously wasted, so that the high-pressure fluid storage container (100) can be efficiently loaded in a narrow space.

In addition, since the length of the connecting member (310) is shortened, the effect of reducing the manufacturing cost can be expected.

Above, one embodiment of the present invention has been described in detail, and below, another embodiment of the present invention will be described with reference to FIG. 5. In other embodiments of the present invention described below, it is obvious that the same or similar configuration as described above can be understood to have the same or similar purpose and to exhibit an effect.

Accordingly, the third groove (211c) can form a space in which a fixing plate (330), a first auxiliary angle (331), and a second auxiliary angle (332) are provided to fix and support the plurality of high-pressure fluid storage containers (100) when they are loaded in a horizontal direction. The contents of the fixing plate (330), the first auxiliary angle (331), and the second auxiliary angle (332) will be described later.

At this time, referring to FIG. 5, the third groove portion (211c) may be formed at the center of the width direction of each side of the frame portion (210), and one side of the third groove portion (211c) may be formed in a form that contacts the plate portion (220). However, the shape of the third groove portion (211c) is not limited thereto, and may be formed in the center of a portion of the frame portion (210) located outside the plate portion (220) so as not to contact the plate portion (220).

Accordingly, when the third groove portion (211c) is formed, the frame portion (210) may be extended in the longitudinal direction compared to when the third groove portion (211c) is not formed, and the plate portion (220) may be provided at a position that is tilted inward from the longitudinal center of the frame portion (210).

Here, the outside may mean the opposite direction to the location where the high-pressure fluid storage tank (100) is installed, and the inside may mean the direction where the high-pressure fluid storage tank (100) is installed.

In addition, the width and length of the third home portion (211c) can be formed so that the fixed plate (330), the first auxiliary angle (331), and the second auxiliary angle (332) described later can pass through.

Accordingly, even when the plurality of high-pressure fluid storage containers (100) are arranged side by side in the horizontal direction, the plurality of high-pressure fluid storage containers (100) can be fixed and supported at the same time, enabling more efficient transport, and the fixing plate (330), the first auxiliary angle (331), and the second auxiliary angle (332) described later are also provided inside the space of the end box (200) to prevent damage due to external force.

Next, the fastening member (300) may further include a fixing plate (330) extending in the arrangement direction of the plurality of high-pressure fluid storage containers (100) so as to simultaneously fix the necks of the plurality of high-pressure fluid storage containers (100) arranged in the horizontal direction, a first auxiliary angle (331) provided at the upper end of the fixing plate (330) along the extension direction of the fixing plate (330) to provide reinforcing force, and a second auxiliary angle (332) provided at the lower end of the fixing plate (330) along the extension direction of the fixing plate (330) to provide reinforcing force.

That is, the fixed plate (330) can simultaneously fix and support each of the high-pressure fluid storage containers (100) arranged in the horizontal direction, and the first auxiliary angle (331) and the second auxiliary angle (332) are respectively provided at the upper and lower ends of the fixed plate (330) along the extension direction of the fixed plate (330) to provide reinforcing force.

At this time, the first auxiliary angle (331) and the second auxiliary angle (332) are each formed to have a cross-section in the shape of the letter 'ㄷ', so that the floor plate formed horizontally can be connected in a direction perpendicular to the fixed plate (330) to provide reinforcing force.

In addition, a first pipe fixing channel may be formed inside the first auxiliary angle (331), and a second pipe fixing channel may be formed inside the second auxiliary angle (332).

At this time, a pipe (not shown in the drawing) through which a predetermined fluid used in the transportation process of the high-pressure fluid storage tank flows is installed in the first pipe fixing channel and the second pipe fixing channel, and accordingly, the pipe can be safely protected by being covered by the side plates of the first auxiliary angle (331) and the second auxiliary angle (332).

Therefore, during the transport process including loading and unloading, the fastening member (300) and the pipe can be safely protected by the end box (200), and the high-pressure fluid storage tank (100) can be loaded in both the longitudinal and transverse directions, thereby enabling more efficient transport.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto, and various embodiments are possible within the scope equivalent to the technical idea of the present invention and the scope of the patent claims to be described below by a person skilled in the art to which the present invention pertains.
