Description

Technical Field

[0001] This application relates to the field of thermal insulation technology, and more specifically, to a medium container and storage system. Background Technology

[0002] Media containers are typically used to contain gaseous, liquid, and solid media. When using media containers to contain these media, some media often require the container to have thermal insulation properties to maintain the original temperature of the contained medium. For example, liquefied hydrogen.

[0003] Currently, heat-insulating media containers typically include a shell and an inner liner inside the shell, with the air between the inner liner and the shell restricting heat transfer between them.

[0004] However, due to the high thermal conductivity of the connection mechanism between the inner liner and the shell, heat transfer between them cannot be effectively limited. In other words, the thermal insulation performance of current media containers is not high enough. Summary of the Invention

[0005] The purpose of this application is to provide a media container and storage system, which connects the inner liner and the shell through a connecting rod to reduce the contact area between the inner liner and the shell, thereby limiting heat transfer between the inner liner and the shell and ultimately improving the thermal insulation performance of the media container.

[0006] In a first aspect, this application provides a medium container, including a shell, an inner liner, and a connecting mechanism; the shell includes a side wall located in the middle of the shell and an end wall located at an end of the shell, the end wall being connected to the end of the side wall and forming a receptacle inside the shell; the shell has a shell length direction extending along the line connecting the two ends of the shell; the inner liner is disposed within the receptacle and has a receiving space for receiving a target medium; the connecting mechanism includes at least three telescopic links and a locking assembly; the length directions of the at least three telescopic links intersect at a point; one end of each telescopic link is movably connected to the inner liner, and the other end of each telescopic link is movably connected to the side wall; one end of the locking assembly is connected to the inner liner, and the other end of the locking assembly is connected to the end wall; the locking assembly is configured to restrict the movement of the inner liner in the shell length direction.

[0007] The aforementioned media container, by employing at least three telescopic connecting rods to connect the inner liner to the side wall of the shell, and using a locking assembly to connect the inner liner to the end wall of the shell, reduces the contact area between the shell and the inner liner, thereby improving the thermal insulation performance of the media container. Furthermore, the telescopic connecting rods allow for adjustment of the inner liner's position within the shell. After adjusting the inner liner's position, the locking assembly secures its position within the shell. This further enhances the ease of use of the media container.

[0008] In conjunction with the first aspect, optionally, one end of the telescopic link is rotatably connected to the inner liner; wherein the axis of rotation is parallel to a plane perpendicular to the length direction of the shell; the other end of the telescopic link is rotatably connected to the side wall; wherein the axis of rotation is parallel to a plane perpendicular to the length direction of the shell.

[0009] The aforementioned media container is rotatably connected to the inner liner and side walls via telescopic connecting rods. Compared to universal joint connections, this is a simpler, more flexible connection method. This simplifies the structure of the media container and reduces its cost.

[0010] In conjunction with the first aspect, optionally, the locking assembly includes a bolt; the end wall is provided with a connecting hole for the bolt to pass through; the inner liner is provided with a threaded hole that matches the bolt; the bolt passes through the connecting hole and is screwed into the threaded hole to lock the shell and the inner liner.

[0011] The aforementioned media container, through bolts and corresponding threaded connections, not only achieves locking of the inner liner but also simplifies the structure of the locking assembly. This, in turn, simplifies the structure of the media container and reduces its cost.

[0012] In conjunction with the first aspect, optionally, the inner liner has an inner liner length direction; wherein, the inner liner length direction is parallel to the shell length direction; and the central axis of the inner liner in the inner liner length direction is collinear with the central axis of the shell in the shell length direction.

[0013] The aforementioned media container, by having its inner liner's central axis along its length collinear with the outer shell's central axis along its length, positions the inner liner at the very center of the shell. This results in a more uniform spatial distribution between the inner liner and the shell, maximizing the thermal insulation effect of the space between them. Ultimately, this further improves the thermal insulation performance of the media container.

[0014] In conjunction with the first aspect, optionally, the number of the retractable links is four; the four retractable links are rotationally symmetrical with respect to the central axis in the length direction of the inner liner.

[0015] The aforementioned media container employs four retractable connecting rods, evenly distributed within the shell, to achieve a balance between the stability of the inner liner connection and the number of retractable connecting rods. In other words, a high level of connection stability is achieved with a minimal number of retractable connecting rods.

[0016] In conjunction with the first aspect, optionally, a connecting rod is provided on the inner liner; a threaded hole is provided on the connecting rod, and the depth direction of the threaded hole is parallel to the length direction of the connecting rod; the connecting rod is connected to the bolt through the threaded hole.

[0017] The aforementioned media container, by incorporating a connecting rod on its inner liner and specifically placing threaded holes on the connecting rod for bolt connection, reduces the requirement for bolt length, thus expanding the range of bolt options and consequently improving the ease of manufacturing the media container.

[0018] Optionally, in conjunction with the first aspect, the locking assembly further includes a first connecting pin and a second connecting pin; the inner liner is also provided with a first connecting seat; the first connecting seat has a first recessed portion for accommodating one end of the connecting rod; one end of the connecting rod is accommodated by the first recessed portion, and the first connecting pin enters from one side of the first recessed portion and passes through one end of the connecting rod, and then exits from the other side of the first recessed portion; the end wall is provided with a second connecting seat; the second connecting seat has a second recessed portion for accommodating the other end of the connecting rod; the other end of the connecting rod is accommodated by the second recessed portion, and the second connecting pin enters from one side of the second recessed portion and passes through the other end of the connecting rod, and then exits from the other side of the second recessed portion.

[0019] In the aforementioned media container, if the connecting hole on the shell is not perfectly aligned with the threaded hole on the connecting rod, the connecting rod can be adjusted by using hinges between it and both the inner liner and the end wall to ensure the threaded hole is aligned with the connecting hole, thus facilitating bolt assembly. This improves the connection stability between the inner liner and the shell.

[0020] In conjunction with the first aspect, optionally, the connecting rod includes a connecting rod body and a hinge joint; one end of the connecting rod body is connected to the first connecting seat via a first connecting pin, and the other end of the connecting rod body is connected to the second connecting seat via a second connecting pin; a threaded hole is provided at the first end of the hinge joint, and the second end of the hinge joint has an annular connecting portion; the first end of the hinge joint is connected to the bolt via the threaded hole; the second end of the hinge joint is inserted into the other end of the connecting rod body and sleeved on the second connecting pin.

[0021] The aforementioned media container connects the connecting rod body and the bolt via a hinge joint that can swing around the second connecting pin. If adjusting the connecting rod body fails to align the threaded hole with the connecting hole, further adjustment of the hinge joint can ensure that the threaded hole aligns with both the connecting hole and the bolt. This further facilitates bolt assembly and, consequently, improves the connection stability between the inner liner and the outer shell.

[0022] In conjunction with the first aspect, the target medium may optionally include liquefied hydrogen.

[0023] The aforementioned medium container, by using the medium container provided in this application for the storage of liquefied hydrogen, provides excellent heat insulation for the stored liquefied hydrogen, thereby limiting the vaporization of the liquefied hydrogen and thus limiting the increase in pressure inside the medium container during the storage of liquefied hydrogen.

[0024] In a second aspect, this application provides a storage system including a media container as described in the first aspect.

[0025] The above-described storage system has the same beneficial effects as the media container provided by the first aspect or any optional embodiment of the first aspect, which will not be repeated here.

[0026] In summary, the media container and storage system provided in this application connect the inner liner and the shell via a connecting rod, thereby reducing the contact area between the inner liner and the shell, limiting heat transfer between them, and improving the thermal insulation performance of the media container. The use of bolts and corresponding threaded connections not only locks the inner liner but also simplifies the structure of the locking assembly. By ensuring that the central axis of the inner liner along its length is collinear with the central axis of the shell along its length, the inner liner is positioned at the very center of the shell, maximizing the thermal insulation effect of the space between the inner liner and the shell. This further improves the thermal insulation performance of the media container. By providing a connecting rod on the inner liner and specifically placing threaded holes on the connecting rod for bolt connection, the bolt length requirement is reduced, thus expanding the range of bolt options. Even when the connecting hole on the shell is not perfectly aligned with the threaded hole on the connecting rod, the connecting rod can be adjusted by using hinges between the connecting rod and both the inner liner and the end wall to ensure the threaded hole aligns with the connecting hole, facilitating bolt assembly. This, in turn, improves the connection stability between the inner liner and the shell. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Please refer to Figure 1 , Figure 1 This is a first perspective view of the medium container 100 provided in this application embodiment. The medium container 100 provided in this application embodiment may include a shell 110, an inner liner 120, and a connecting mechanism 130. The shell 110 may include a side wall 111 located in the middle of the shell 110 and an end wall 112 located at the end of the shell 110. The end wall 112 may be connected to the end of the side wall 111 and may form a receiving body inside the shell 110. The shell 110 may have a shell length direction extending along the line connecting the two ends of the shell 110. The inner liner 120 may be disposed in the receiving body and may have a receiving space for receiving the target medium. The connecting mechanism 130 may include at least three telescopic links 140 and a locking assembly 131. The length directions of the at least three telescopic links 140 may intersect at a point. One end of the telescopic link 140 may be movably connected to the inner liner 120, and the other end of the telescopic link 140 may be movably connected to the side wall 111. One end of the locking assembly 131 can be connected to the inner liner 120, and the other end of the locking assembly 131 can be connected to the end wall 112. The locking assembly 131 can be configured to restrict the movement of the inner liner 120 in the length direction of the housing.

[0039] There can be two end walls 112, each connected to one end of the side wall 111. The connection can be made by welding or by integral molding, etc. The inner liner 120 can also have a structure similar to the shell 110. The target medium can be a liquefied fuel medium, such as liquefied hydrogen.

[0040] The retractable connecting rods 140 are movably connected to the inner liner 120 and the side walls 111, respectively. Specifically, this connection can be a hinge connection or a universal joint connection, etc. The connection between the shell 110 and the inner liner 120 can be achieved by one side wall 111 being connected using at least three retractable connecting rods 140 as described in the embodiments of this application, while the other side wall 111 is connected using other connection methods known to those skilled in the art. Alternatively, both side walls 111 can be connected using at least three retractable connecting rods 140 as described in the embodiments of this application. This connection of at least three retractable connecting rods 140 between the inner liner 120 and the shell 110 allows the inner liner 120 to move along the length of the shell.

[0041] To improve the stability of the inner liner 120 within the housing 110, a locking assembly 131 connects the inner liner 120 to the end wall 112 of the housing 110. The locking assembly 131 may specifically be a fixed-length connecting rod 121 or other components, and is non-movably connected to both the inner liner 120 and the end wall 112 of the housing 110.

[0042] In the above implementation process, by using at least three telescopic connecting rods 140 to connect the inner liner 120 to the side wall 111 of the shell 110, and by using a locking assembly 131 to connect the inner liner 120 to the end wall 112 of the shell 110, the contact area between the shell 110 and the inner liner 120 is reduced, thereby improving the heat insulation performance of the medium container 100. Furthermore, by connecting the inner liner 120 to the side wall 111 of the shell 110 via the telescopic connecting rods 140, the position of the inner liner 120 inside the shell 110 is adjustable. After adjusting the position of the inner liner 120, the locking assembly 131 is used to connect the inner liner 120 to the end wall 112 of the shell 110 to fix the position of the inner liner 120 inside the shell 110. This further improves the ease of use of the medium container 100.

[0043] Please continue to refer to Figure 1 In some alternative embodiments, one end of the telescopic link 140 can be rotatably connected to the inner liner 120. The axis of rotation can be parallel to a plane perpendicular to the length direction of the housing. The other end of the telescopic link 140 can be rotatably connected to the side wall 111. The axis of rotation can also be parallel to a plane perpendicular to the length direction of the housing.

[0044] The retractable connecting rod 140 is rotatably connected to the inner liner 120 and the side wall 111, respectively, by means of a pin whose length direction is parallel to a plane perpendicular to the length direction of the shell. Specifically, the pin can pass through the inner liner 120 and the retractable connecting rod 140, and the side wall 111 and the retractable connecting rod 140.

[0045] In the above implementation process, the retractable connecting rod 140 is rotatably connected to the inner liner 120 and the side wall 111 respectively. Compared with universal joint connections and other methods, this is a simpler movable connection method. This simplifies the structure of the medium container 100 and reduces its cost.

[0046] Please refer to Figure 2 , Figure 2 This is a partial enlarged view of the medium container 100 provided in an embodiment of this application. In some optional embodiments, the locking assembly 131 may include a bolt 1321. A connecting hole for the bolt 1321 to pass through may be provided on the end wall 112. A threaded hole matching the bolt 1321 may be provided on the inner liner 120. The bolt 1321 can pass through the connecting hole and can be screwed into the threaded hole to lock the shell 110 and the inner liner 120.

[0047] The length of bolt 1321 can be determined based on the distance between the inner liner 120 and the end wall 112. After the inner liner 120, the telescopic connecting rod 140, and the outer shell are assembled, and the position of the inner liner 120 inside the shell 110 is determined, bolt 1321 can be inserted through the connecting hole on the end wall 112 and then into the threaded hole on the inner liner 120. Tightening bolt 1321 will lock the inner liner 120.

[0048] In the above implementation process, the inner liner 120 is locked by bolts 1321 and corresponding threaded connections, while the structure of the locking assembly 131 is simplified. This also simplifies the structure of the medium container 100 and reduces its cost.

[0049] Please continue to refer to Figure 1 In some optional embodiments, the inner liner 120 may have an inner liner length direction. This inner liner length direction may be parallel to the shell length direction. The central axis of the inner liner 120 in the inner liner length direction may be collinear with the central axis of the shell 110 in the shell length direction.

[0050] For example, the inner liner 120 and the outer shell 110 are cylindrical in shape with different dimensions. The central axis of the cylinder of the inner liner 120 is collinear with the central axis of the cylinder of the outer shell 110, so that the inner liner 120 is located at the center of the outer shell 110.

[0051] In the above-described process, by ensuring that the central axis of the inner liner 120 along its length is collinear with the central axis of the shell 110 along its length, the inner liner 120 is positioned at the very center of the shell 110. This results in a more uniform spatial distribution between the inner liner 120 and the shell 110, thereby maximizing the thermal insulation effect of the space between them. Ultimately, this further improves the thermal insulation performance of the medium container 100.

[0052] Please refer to Figure 3 , Figure 3 This is a second perspective view of the medium container 100 provided in the embodiments of this application. In some optional embodiments, the number of telescopic links 140 can be four. The four telescopic links 140 can be rotationally symmetrical with respect to the central axis in the length direction of the inner liner.

[0053] In other words, when there are four telescopic links 140, the projection of the four telescopic links 140 onto a plane perpendicular to the length of the housing is a cross shape.

[0054] In the above implementation process, four retractable connecting rods 140 are specifically adopted and evenly distributed within the shell 110. This balances the connection stability of the inner liner 120 with the number of retractable connecting rods 140. In other words, a high connection stability of the inner liner 120 is achieved with a minimum number of retractable connecting rods 140.

[0055] Please continue to refer to Figure 2 In some alternative embodiments, a connecting rod 121 may be provided on the inner liner 120. A threaded hole may be provided on the connecting rod 121, and the depth direction of the threaded hole may be parallel to the length direction of the connecting rod 121. The connecting rod 121 can be connected to a bolt 1321 through the threaded hole.

[0056] The connecting rod 121 can be solid or hollow. Its material can be a fiber-reinforced resin composite or other material with good thermal insulation properties. The connection between the connecting rod 121 and the inner liner 120 can be detachable, fixed, or movable, excluding the length direction of the inner liner.

[0057] In the above implementation process, a connecting rod 121 is provided on the inner liner 120, and a threaded hole is specifically provided on the connecting rod 121 to connect the bolt 1321. This reduces the requirement for the length of the bolt 1321, that is, it expands the range of bolts that can be selected, thereby improving the manufacturing convenience of the medium container 100.

[0058] Please continue to refer to Figure 2In some optional embodiments, the locking assembly 131 may further include a first connecting pin 1322 and a second connecting pin 1323. A first connecting seat 122 may also be provided on the inner liner 120. The first connecting seat 122 may have a first recess to accommodate one end of the connecting rod 121. One end of the connecting rod 121 can be accommodated by the first recess, and the first connecting pin 1322 can enter and pass through one end of the connecting rod 121 from one side of the first recess, and then exit from the other side of the first recess. A second connecting seat 113 may be provided on the end wall 112. The second connecting seat 113 may have a second recess to accommodate the other end of the connecting rod 121. The other end of the connecting rod 121 can be accommodated by the second recess, and the second connecting pin 1323 can enter and pass through one side of the second recess, and then exit from the other side of the second recess.

[0059] In other words, the connecting rod 121 is hinged to the inner liner 120 and the end wall 112 via the first connecting pin 1322 and the second connecting pin 1323, respectively. This enables the connecting rod 121 to be movably connected to the inner liner 120 and the end wall 112 via hinges. Even when the connecting hole on the housing 110 is not perfectly aligned with the threaded hole on the connecting rod 121, the connecting rod 121 can be adjusted via this movable connection.

[0060] In the above implementation process, when the connecting hole on the shell 110 is not completely aligned with the threaded hole on the connecting rod 121, the connecting rod 121 can be adjusted by using the hinge connections between the connecting rod 121 and the inner liner 120 and the end wall 112 respectively, so that the threaded hole is aligned with the connecting hole, which facilitates the assembly of the bolt 1321. This improves the connection stability between the inner liner 120 and the shell 110.

[0061] Please continue to refer to Figure 2 In some alternative embodiments, the connecting rod 121 may include a connecting rod 121 body and a hinge joint 1212. One end of the connecting rod 121 body can be connected to a first connecting seat 122 via a first connecting pin 1322, and the other end of the connecting rod 121 body can be connected to a second connecting seat 113 via a second connecting pin 1323. A threaded hole may be provided at the first end of the hinge joint 1212, and the second end of the hinge joint 1212 may have an annular connecting portion. The first end of the hinge joint 1212 can be connected to a bolt 1321 via the threaded hole. The second end of the hinge joint 1212 can be inserted into the other end of the connecting rod 121 body and can be sleeved on the second connecting pin 1323.

[0062] In other words, the connecting rod 121 body is connected to the bolt 1321 via a movable hinge joint 1212. Since the hinge joint 1212 is sleeved on the second connecting pin 1323, the hinge joint 1212 can swing around the second connecting pin 1323.

[0063] In the above implementation process, the connecting rod 121 body and the bolt 1321 are connected by a hinge joint 1212 that can swing around the second connecting pin 1323. If adjusting the connecting rod 121 body still cannot make the threaded hole align with the connecting hole, the hinge joint 1212 can be further adjusted to make the threaded hole align with the connecting hole and the bolt 1321. This further facilitates the assembly of the bolt 1321. Thus, the connection stability between the inner liner 120 and the shell 110 is further improved.

[0064] In some alternative implementations, the target medium may include liquefied hydrogen.

[0065] In other words, the medium container 100 provided in the preceding embodiments of this application is used for the storage of liquefied hydrogen.

[0066] In the above implementation process, by using the medium container 100 provided in the preceding embodiments of this application for the storage of liquefied hydrogen, the stored liquefied hydrogen is well insulated, thereby limiting the vaporization of liquefied hydrogen and thus limiting the increase in pressure inside the medium container 100 during the storage of liquefied hydrogen.

[0067] Based on the same concept, the storage system provided in this application embodiment may include the media container 100 described in the preceding embodiments.

[0068] In addition to the medium container 100, the storage system may also include components such as pressure gauges, level gauges, and operating valves.

[0069] The above implementation process can be the same as that of the medium container 100 described in the previous embodiments, and will not be repeated here.

[0070] In summary, the medium container 100 and storage system provided in the various embodiments of this application connect the inner liner 120 and the shell 110 via a connecting rod, thereby reducing the contact area between the inner liner 120 and the shell 110, thus limiting heat transfer between the inner liner 120 and the shell 110 and improving the thermal insulation performance of the medium container 100. The inner liner 120 is locked using bolts 1321 and corresponding threaded connections, while the structure of the locking assembly 131 is simplified. By ensuring that the central axis of the inner liner 120 along its length is collinear with the central axis of the shell 110 along its length, the inner liner 120 is positioned at the very center of the shell 110, maximizing the thermal insulation effect of the space between the inner liner 120 and the shell 110. This further improves the thermal insulation performance of the medium container 100. A connecting rod 121 is provided on the inner liner 120, and a threaded hole is specifically provided on the connecting rod 121 to connect the bolt 1321. The requirement for the length of bolt 1321 has been reduced, meaning the range of bolts that can be selected for 1321 has been expanded. When the connecting hole on the housing 110 is not perfectly aligned with the threaded hole on the connecting rod 121, the connecting rod 121 can be adjusted via hinges connecting it to both the inner liner 120 and the end wall 112, ensuring the threaded hole aligns with the connecting hole, thus facilitating the assembly of bolt 1321. This, in turn, improves the connection stability between the inner liner 120 and the housing 110.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
