Description

{Supporting device for high-pressure fluid storage container}

The present invention relates to a support device for a pressure vessel equipped with a valve protection cap, and more specifically, to a support device for a pressure vessel equipped with a valve protection cap, which safely and stably loads the pressure vessel on a transport vehicle using an end box when transporting the pressure vessel to a specific location, and prevents a major accident in advance by preventing the valve connected to a hydrogen tank from being damaged and causing hydrogen gas to leak due to transport in an exposed state by fastening a valve protection cap to the end box.

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 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, 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.

In addition, since the valve connected to the hydrogen tank is transported in an exposed state, the valve may break and hydrogen gas may leak, which may cause a major accident.

Therefore, there is an increasing need for the development of a support device for a pressure vessel equipped with a valve protection cap to solve such problems.

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

A support device for a pressure vessel equipped with a valve protection cap according to one embodiment of the present invention includes a pressure vessel (100), an end box (200), a fastening part (300), and a valve protection cap (400).

First, the pressure vessel (100) may be a vessel storing high-pressure gas such as hydrogen, LNG, LN2, CNG, etc., and among these, hydrogen may preferably be stored.

Next, the end box (200) can be formed to be coupled to one side of the pressure vessel (100) and surround the neck of the pressure vessel (100).

The above end box (200) is intended to support one side of the pressure vessel (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 pressure vessel (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 movable 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 pressure vessel (100) passes through it.

Accordingly, the pressure vessel (100) can be supported more stably on the end box (200) since 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 pressure vessel (100) expands or contracts due to high-pressure gas stored therein or is shaken by 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 part (211a) and the second groove part (211b) may be the same as the first groove part (211a) and the second groove part (211b), and the first groove part (211a) and the second groove part (211b) may be distinguished according to the position where they are formed on the upper or lower surface of the frame part (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 pressure vessel (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 (211a) and the second groove (211b) can be formed to correspond to the diameter of the neck of the pressure vessel (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 pressure vessel (100) does not reach when the end box (200) is coupled to one end of the pressure vessel (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 pressure vessel (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 external force.

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

At this time, when two or more of the above pressure vessels (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 pressure vessels (100).

In addition, when two or more of the pressure vessels (100) are loaded, the end boxes (200) can be loaded in the radial direction of the plurality of pressure vessels (100) so that the second groove (211 b) 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 pressure vessel (100) and the end box (200) can be loaded in an accurate position when the pressure vessel (100) and the end box (200) are loaded in the radial direction of the plurality of pressure vessels (100), thereby enabling the pressure vessel (100) and the end box (200) to be loaded in an accurate position more efficiently than when loading based only on the side of the end box (200).

Next, the above-mentioned fastening portion (300) can connect the plurality of pressure vessels (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 pressure vessels (100) and a bracket member (320) that is connected at both ends to the end box (200) to fix 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 pressure vessels (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 pressure vessel (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 to be described below, it is obvious that the same or similar configuration as that described above can be understood to have the same or similar purpose and to exhibit an effect.

First, as illustrated in FIG. 5, a support device of a pressure vessel according to another embodiment of the present invention may further include a third groove (211c), a fixed plate (330), a first auxiliary angle (331), and a second auxiliary angle (332).

First, the groove portion (211) is formed on a side of the frame portion (210) and may further include a third groove portion (211c) that is formed to have a wider width than the first groove portion (211a) and the second groove portion (211b).

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 pressure vessels (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 home 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 come into contact with 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 position where the pressure vessel (100) is installed, and the inside may mean the direction where the pressure vessel (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 pressure vessels (100) are arranged side by side in the horizontal direction, the plurality of pressure vessels (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 pressure vessels (100) so as to simultaneously fix the necks of the plurality of pressure vessels (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 pressure vessels (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 longitudinal 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 gas used in the transport process of the pressure vessel 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 pressure vessel (100) can be loaded in both the longitudinal and transverse directions, thereby enabling more efficient transport.

In addition, a valve protection cap (400) according to another embodiment of the present invention illustrated in FIGS. 6 to 10 is fastened to one side of the end box (200) to protect a valve provided in a pressure vessel (100).

The above valve protection cap (400) is fastened to the first groove (211a) from which the valve (B) of the pressure vessel (100) protrudes among the grooves divided by the bulkhead in the end box (200).

That is, the valve protection cap (400) is formed with the same size and shape as the first groove (211a) of the end box (200), and is fastened to the end box (200) using a bolt or the like through a fastening hole (201, 401) using a flange (410) formed on the outer periphery of the valve receiving portion (420).

At this time, as shown in Fig. 9, when fastening the valve protection cap (400), a shock absorbing member (411) may be additionally provided at the area where the flange (410) and the end box (200) are in close contact, thereby absorbing shock transmitted from the outside and preventing the valve protection cap (400) from being damaged.

And, a valve receiving portion (420) is provided to protrude from one side of the flange (410). Accordingly, the valve (B) connected to the pressure vessel (100) is received inside the valve receiving portion (420), thereby protecting the valve (B) from external impact and preventing it from being damaged.

At this time, the valve receiving portion (420) is formed with the upper and lower surfaces open. This is to prevent interference with the valve receiving portion (420) by connecting it in a vertical direction when connecting a separate device (e.g., connecting member, 310) to the pressure vessel (100).

That is, the reason why the valve receiving portion (420) is opened at the top and bottom is that when the pressure vessel (100) is placed, it is placed inside the end box (200) that is interconnected, so that one end of a separate device (e.g., connecting member, 310) is directed upward and the other end is directed downward, so that even if the end protrudes somewhat from the end box (200), interference does not occur.

At this time, as shown in Fig. 9, one end of the front plate (421) formed to be separated from the front of the valve receiving portion (420) is fastened to the side plate (423) on the same side that is in close contact with the front plate (421) by a hinge (424) so that the front plate (421) can be opened, thereby allowing the valve (B) and the like to be replaced and removed from the pressure vessel (100).

And as shown in Fig. 10, instead of forming the valve receiving portion (420) as an integral part with the flange (410), a hinge (424) is used, and one side of the hinge (424) is fastened to the side plate (423) of the valve receiving portion (420) and the other side is fastened to the flange (410), thereby opening the entire valve receiving portion (420) as needed to allow the valve (B) or a separate device (connecting member, 310) to be fastened or separated from the pressure vessel (100).

At this time, it is desirable to provide a separate locking device (not shown) in the opposite direction to which the hinge (424) is fastened.

And an opening (430) is provided on the front side of the valve receiving portion (420).

Accordingly, when a separate device (e.g., connecting member, 310) is horizontally fastened to a valve or pressure vessel (100) accommodated in a valve receiving portion (420) integrally formed with a flange (410), it can be fastened or separated through the opening (430), and this is to prevent the separate device (e.g., connecting member, 310) fastened horizontally from interfering with the valve receiving portion (420) even if it protrudes partially.

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.
