Description

Technical Field

[0001] This application relates to the field of liquefied gas storage equipment technology, and in particular to a leveling structure and liquefied gas storage equipment. Background Technology

[0002] Liquefied petroleum gas (LPG) storage equipment includes a container wall. The inner surface of the container wall has numerous uneven areas, resulting in poor flatness of the LPG storage equipment. A leveling structure is installed on the inner surface of the container wall to improve its flatness, thereby improving the overall flatness of the LPG storage equipment.

[0003] In related technologies, the process of setting up the leveling structure requires a lot of time, which increases the production cost of liquefied gas storage equipment. Utility Model Content

[0004] This application provides a leveling structure and a liquefied gas storage device, which shortens the assembly time of the leveling structure and thus reduces the production cost of the liquefied gas storage device.

[0005] In a first aspect, this application provides a leveling structure applied to a liquefied gas storage device. The leveling structure includes multiple support wedges. Each support wedge includes a support body and a first magnet. The support body includes a first surface disposed along a first direction, where the first direction is the thickness direction of the container wall in the liquefied gas storage device. The first surface is attached to the inner surface of the container wall, and a first mounting groove is formed on the first surface. The container wall includes a first structural block, which is made of a magnetically attractive metal. The first magnet is used to attract the first structural block. The first magnet is connected in the first mounting groove, and the end of the first magnet near the opening of the first mounting groove is not higher than the first surface. The ends of the first magnets in the multiple support wedges near the opening of the first mounting groove are all N poles. Alternatively, the ends of the first magnets in the multiple support wedges near the opening of the first mounting groove are all S poles.

[0006] The leveling structure provided in the first aspect of this application includes multiple support wedges, enabling the leveling of uneven portions on the inner surface of the container wall. A first surface of a support body within each support wedge, positioned along a first direction, adheres to the inner surface of the container wall, replacing the uneven portions. A first magnet within each support wedge is connected to the support body via a first mounting groove on the first surface, connecting the first surface of the support body to a first structural block of the container wall. This ensures a secure connection between the support wedge and the container wall while facilitating easier and faster disassembly and installation of the support wedge, thereby shortening the assembly time of the leveling structure. Furthermore, the end of the first magnet near the opening of the first mounting groove is not higher than the first surface, allowing the first surface to fully adhere to the inner surface of the container wall, ensuring a stable connection between the support wedge and the container wall. Additionally, the ends of the first magnets in the multiple support wedges near the opening of the first mounting groove all have N / S poles, ensuring that the magnetic field directions of the first surfaces of the multiple supports are aligned, thus enabling the first structural block of the container wall to smoothly engage and connect with the multiple support wedges.

[0007] In one possible design, multiple support wedges are stacked along a first direction. The support body includes a second surface. The second surface and the first surface are opposite to each other in the first direction. A second mounting groove is formed on the second surface. A second magnet is connected within the second mounting groove, with the end of the second magnet near the opening of the second mounting groove not exceeding the height of the second surface. The second magnet is used to attract the first magnets among the other support wedges. When the ends of the first magnets in the multiple support wedges near the opening of the first mounting groove are all N poles, the ends of the second magnets near the opening of the second mounting groove are all S poles. Alternatively, when the ends of the first magnets in the multiple support wedges near the opening of the first mounting groove are all S poles, the ends of the second magnets near the opening of the second mounting groove are all N poles.

[0008] Based on the description of the above embodiments, multiple support wedges are stacked along a first direction, so that the leveling structure has different heights in the first direction. This allows multiple depressions or protrusions of varying degrees on the inner surface of the container wall to be leveled into a single plane, thereby further improving the leveling effect of the leveling structure. A second magnet is connected to a second mounting groove on the second surface of the support body, allowing the second magnet to attract the first magnet on another support wedge. This ensures a firm connection between the multiple support wedges while making the disassembly and installation of the multiple support wedges more convenient and faster, reducing the assembly steps and time of the multiple support wedges, further shortening the assembly time of the leveling structure, and thus reducing the production cost of the liquefied gas storage equipment. Furthermore, the end of the second magnet near the opening of the second mounting groove is not higher than the second surface, which ensures the stability of the connection between the multiple support wedges. In addition, when the ends of the first magnets in the multiple support wedges near the opening of the first mounting groove are all N / S poles, the ends of the second magnets near the opening of the second mounting groove are all S / N poles, allowing the second surface of one support wedge to smoothly attract the first surface of another support wedge.

[0009] In one possible design, the support wedge includes multiple first magnets and multiple second magnets. Multiple first mounting slots are provided on a first surface. Multiple second mounting slots are provided on a second surface. The number of first magnets, second magnets, first mounting slots, and second mounting slots are equal. The positions of the first mounting slots and second mounting slots correspond one-to-one in the first direction.

[0010] Based on the description of the above embodiments, the support wedge includes multiple first magnets and multiple second magnets, which can increase the connection area between the multiple support wedges and the container wall, and reduce the volume of the first and second magnets, thereby improving the stability of the connection between the multiple support wedges and the container wall while reducing the production cost of the liquefied gas storage equipment. The number of first magnets, second magnets, first mounting slots, and second mounting slots are the same, and the positions of the first and second mounting slots in the first direction correspond one-to-one, so that each second magnet can be attracted and connected to one first magnet, thereby ensuring the leveling effect of the leveling structure.

[0011] In one possible design, the first mounting slot and the corresponding second mounting slot are through holes extending through the support. Both the first magnet and the second magnet are connected within the through holes.

[0012] Based on the description of the above embodiments, a first mounting groove and a corresponding second mounting groove are a through hole in the support body, and the first magnet and the second magnet are both connected in the through hole. This allows the second magnet to correspond to and be attracted to the first magnet, while reducing the number of holes to be drilled on the support, thereby shortening the drilling time, saving assembly time, and thus reducing the production cost of the liquefied gas storage equipment.

[0013] In one possible design, the support includes an auxiliary structure. The auxiliary structure is a countersunk hole or groove formed on the first surface.

[0014] Based on the description of the above embodiments, the auxiliary structure is a countersunk hole or groove opened on the second surface, which makes it convenient for the operator to pick up the support wedge, thereby optimizing the leveling structure.

[0015] In one possible design, an anti-slip structure is provided in the countersunk hole or groove.

[0016] Based on the description of the above embodiments, the anti-slip structure is used to prevent the support wedge from slipping or falling from the operator's hand during the handling process, saving the operator's handling time and shortening the assembly time of the leveling structure, thereby further reducing the production cost of the liquefied gas storage equipment.

[0017] In one possible design, the first magnet can be detachably connected within the first mounting slot.

[0018] In one possible design, the second magnet can be detachably connected to the second mounting slot.

[0019] Based on the description of the above embodiments, the first magnet is detachably connected to the first mounting slot, allowing for easy replacement and maintenance. Similarly, the second magnet is detachably connected to the second mounting slot, allowing for easy replacement and maintenance. In summary, replacing or maintaining only the first or second magnet reduces the minimum maintenance unit of the leveling structure, lowers the maintenance cost of the leveling structure, and consequently reduces the production cost of the liquefied gas storage equipment.

[0020] In one possible design, both the first and second magnets are permanent magnets made of bonded neodymium iron boron material.

[0021] Based on the description of the above embodiments, both the first magnet and the second magnet are permanent magnets made of bonded neodymium iron boron material, which makes the first magnet and the second magnet less brittle and reduces the production cost of the first magnet and the second magnet, thereby reducing the production cost of the liquefied gas storage equipment.

[0022] Secondly, this application provides a liquefied gas storage device, including a container wall and a leveling structure as described in any of the above embodiments. The leveling structure is disposed on the inner surface of the container wall.

[0023] The beneficial effects of the liquefied gas storage device provided in the second aspect above can be found in the first aspect and the beneficial effects of the various possible embodiments of the first aspect, and will not be repeated here. Attached Figure Description

[0047] Liquefied petroleum gas (LPG) storage equipment includes a container wall. The inner surface of the container wall has numerous uneven areas, resulting in poor flatness of the LPG storage equipment. A leveling structure is installed on the inner surface of the container wall to improve its flatness, thereby improving the overall flatness of the LPG storage equipment.

[0048] In related technologies, the process of setting up the leveling structure requires a lot of time, which increases the production cost of liquefied gas storage equipment.

[0049] Based on this, this application provides a leveling structure and a liquefied gas storage device. By incorporating a magnet in the leveling structure, the supporting wedge is magnetically connected to the container wall, shortening the assembly time of the leveling structure and thus reducing the production cost of the liquefied gas storage device. The following is in conjunction with... Figures 1-5 Please provide a detailed explanation.

[0050] In a first aspect, this application provides a leveling structure 100 applied to a liquefied gas storage device. The leveling structure 100 includes multiple support wedges 1. Each support wedge 1 includes a support body 11 and a first magnet 12. The support body 11 includes a first surface 111 disposed along a first direction X. The first direction X is the thickness direction of the container wall 200 in the liquefied gas storage device. The first surface 111 is attached to the inner surface of the container wall 200, and a first mounting groove 1111 is formed on the first surface 111. The container wall 200 includes a first structural block (not shown in the figure), which is made of a magnetically attractive metal. The first magnet 12 is used to attract the first structural block. The first magnet 12 is connected in the first mounting groove 1111, and the end of the first magnet 12 near the opening of the first mounting groove 1111 is not higher than the first surface 111. The ends of the first magnets 12 in the multiple support wedges 1 near the opening of the first mounting groove 1111 all have a North pole (N pole a). Alternatively, the first magnet 12 in the multiple support wedges 1 has an S pole b at the end near the opening of the first mounting groove 1111.

[0051] Because the inner surface area of ​​the container wall 200 in the liquefied gas storage equipment is too large, it is impossible to guarantee a high degree of flatness on the inner surface of the container wall 200 during its manufacturing process. In other words, there may be multiple uneven areas on the inner surface of the container wall 200. Based on this, if... Figure 1 As shown, the leveling structure 100 can be multiple support wedges 1 arranged on the inner surface of the container wall 200. When there are multiple uneven areas on the inner surface of the container wall 200, one or more support wedges 1 can be arranged at the uneven areas to replace the uneven parts of the inner surface of the container wall, thereby improving the flatness of the inner surface of the container wall 200 and achieving leveling of the inner surface of the container wall 200. Specifically, the support wedges 1 can be small plate-like structures, allowing multiple support wedges 1 to be arranged on the inner surface of the container wall 200, so that multiple uneven areas on the inner surface of the container wall 200 can be leveled. In addition, the small area of ​​the support wedges 1 allows even small uneven areas to be compensated, further improving the flatness of the inner surface of the container wall 200.

[0052] The support wedge 1 may include a support body 11. Specifically, the support body 11 may be an insulated plate-like structure. For example, the support body may be a single-layer wood board, composite wood board, or plywood, etc., and this application does not specifically limit it in this regard.

[0053] Furthermore, the support wedge 1 may also include a first magnet 12, which has magnetic properties and can be attracted and connected to a magnetically dissipating metal material. The first magnet 12 is disposed on the first surface 111 of the support body 11, so that the first surface 111 of the support body 11 can be connected to the magnetically dissipating metal material via the first magnet 12.

[0054] The container wall 200 includes a first structural block, which is made of a magnetically disintegrating metal. When the container wall 200 is made of a non-metallic material, the first structural block can be embedded within the container wall 200. When the container wall 200 is made of a magnetically disintegrating metal, the first structural block can be the container wall 200 itself. Therefore, the first magnet 12 is attracted to the first structural block, allowing the first surface 111 of the support 11 to connect to the inner surface of the container wall 200. The support 11 achieves leveling of the inner surface of the container wall 200 through its own thickness. It should be noted that when the liquefied gas storage equipment is a land-based storage tank, the container wall 200 is a non-metallic tank wall, such as a concrete tank wall. In this case, the first structural block can be a metal plate or a keel structure encased within the container wall 200. Specifically, the keel structure can improve the structural strength of the container wall 200. When the liquefied gas storage equipment is a marine storage tank, the container wall 200 is a tank wall made of a magnetically disintegrating metal. In this case, the first structural block can be the container wall 200 itself.

[0055] Furthermore, compared to adhesive bonding between the support wedge 1 and the inner surface of the container wall 200, such as tape, double-sided tape, and structural adhesive, the first magnet 12 provides a magnetic connection between the support wedge 1 and the inner surface of the container wall 200. This ensures a strong connection while making the disassembly and installation of the support wedge 1 more convenient and quick, and enabling its recycling. Moreover, the support wedge 1 leaves no adhesive residue after disassembly, allowing it to be directly stacked and stored after recycling, or reused directly. This eliminates the need for de-adhesive removal after recycling, reducing assembly steps and time, and thus shortening the assembly time of the leveling structure 100.

[0056] Specifically, such as Figure 2 and Figure 3 As shown, the support body 11 includes a first surface 111 disposed along a first direction X. The first direction X is the thickness direction of the container wall 200 of the liquefied gas storage device. The first surface 111 is in contact with the container wall 200, and a first mounting groove 1111 is formed on the first surface 111. A first magnet 12 is installed in the first mounting groove 1111, allowing the first magnet 12 to be disposed on the first surface 111 of the support body 11.

[0057] Furthermore, the end of the first magnet 12 near the opening of the first mounting groove 1111 is not higher than the first surface 111, so as to avoid the first magnet 12 protruding from the first surface 111 and affecting the flatness of the first surface 111, thereby enabling the first surface 111 to be completely in contact with the inner surface of the container wall 200, so as to ensure a stable connection between the support wedge 1 and the container wall 200.

[0058] Furthermore, the ends of the first magnets 12 in the plurality of support wedges 1 that are near the opening of the first mounting groove 1111 are all N poles a. Alternatively, the ends of the first magnets 12 in the plurality of support wedges 1 that are near the opening of the first mounting groove 1111 are all S poles b. When a plurality of support bodies 11 are connected to a first structural block, making the ends of the first magnets 12 in the plurality of support wedges 1 that are near the opening of the first mounting groove 111 have the same polarity can make the magnetic field direction of the first surface 111 of the plurality of support bodies 11 consistent, thereby enabling the aforementioned first structural block to be smoothly attracted and connected to the plurality of support wedges 1.

[0059] In summary, the leveling structure 100 provided in the first aspect of this application includes a plurality of support wedges 1, which enable the leveling of uneven portions on the inner surface of the container wall 200. The first surface 111 of the support body 11 in the support wedge 1, arranged along the first direction X, fits against the inner surface of the container wall 200, replacing the uneven portions of the inner surface of the container wall 200. The first magnet 12 in the support wedge 1 is connected to the support body 11 through a first mounting groove 1111 provided on the first surface 111, so that the first surface 111 of the support body 11 is connected to the first structural block of the container wall 200. This ensures a firm connection between the support wedge 1 and the container wall 200 while making the disassembly and installation of the support wedge 1 more convenient and quick, thereby shortening the assembly time of the leveling structure 100. Furthermore, the end of the first magnet 12 near the opening of the first mounting groove 1111 is not higher than the first surface 111, so that the first surface 111 can be completely attached to the inner surface of the container wall 200, ensuring a stable connection between the support wedge 1 and the container wall 200. In addition, the ends of the first magnets 12 in the plurality of support wedges 1 near the opening of the first mounting groove 1111 are all N / S poles, which can make the magnetic field direction of the first surface 111 of the plurality of support bodies 11 be consistent, so that the first structural block of the container wall 200 can be smoothly attracted and connected to the plurality of support wedges 1.

[0060] Furthermore, in order to further improve the leveling effect of the leveling structure 100 and save the assembly time of the leveling structure 100, the present application can also make the following improvements:

[0061] In some embodiments, a plurality of support wedges 1 are stacked along a first direction X. The support body 11 includes a second surface 112. The second surface 112 and the first surface 111 are opposite to each other in the first direction X. A second mounting groove 1121 is formed on the second surface 112. A second magnet 13 is connected within the second mounting groove 1121, and the end of the second magnet 13 near the opening of the second mounting groove 1121 is not higher than the second surface 112. The second magnet 13 is used to attract the first magnets 12 in the other support wedges 1. When the ends of the first magnets 12 in the plurality of support wedges 1 near the opening of the first mounting groove 1111 are all N poles a, the ends of the second magnets 13 near the opening of the second mounting groove 1121 are all S poles b. Alternatively, when the ends of the first magnets 12 in the plurality of support wedges 1 near the opening of the first mounting groove 1111 are all S poles b, the ends of the second magnets 13 near the opening of the second mounting groove 1121 are all N poles a.

[0062] The uneven surface of the container wall can include protruding and recessed portions. Based on this, such as... Figure 4 As shown, multiple support wedges 1 are stacked along the first direction X, so that the leveling structure 100 has different heights in the first direction X, so as to adapt to the protruding and recessed parts on the inner surface of the container wall 200, thereby further improving the leveling effect of the leveling structure 100.

[0063] For example, a support wedge 1 has a thickness of 4 mm in the first direction X. There are two recessed portions on the inner surface of the container wall 200, where the first recessed portion is 8 mm below the reference plane and the second recessed portion is 12 mm below the reference plane. In this case, two support wedges 1 can be stacked along the first direction X, connecting them to the first recessed portion, and three support wedges 1 can be stacked along the first direction X, connecting them to the second recessed portion, thereby leveling the two recessed portions and improving the flatness of the inner surface of the container wall 200. It should be noted that the reference plane can be a preset target plane, and the number of stacked support wedges 1 is not specifically limited in this application.

[0064] Furthermore, the support wedge 1 can include various thicknesses, for example, the thickness of the support wedge can range from 4mm to 16mm. For example, the thickness of the support wedge can be 4mm, 4.2mm, 4.4mm, 4.6mm, 7.8mm, 8.0mm, 10.0mm, 12.0mm, 16.0mm, etc. Support wedges 1 of various thicknesses can be arranged and combined arbitrarily so that multiple recesses or protrusions of different degrees on the inner surface of the container wall 200 can be leveled into a plane.

[0065] Specifically, the support 11 includes a second surface 112. The second surface 112 and the first surface 111 are opposite to each other in the first direction X. Figure 1 and Figure 4 As shown, the first surface 111 faces the inner surface of the container wall 200, and the second surface 112 faces away from the inner surface of the container wall 200. Therefore, the support wedges 1 can be stacked on the second surface 112.

[0066] Specifically, such as Figure 3 As shown, a second mounting groove 1121 is formed on the second surface 112 of one of the support bodies 11. A second magnet 13 is connected in the second mounting groove 1121. The second magnet 13 attracts the first magnet 12 provided on the other support body 11, thereby realizing the stacking of two support wedges 1. Similarly, the stacking method of two or more support wedges 1 is the same as the stacking method of two support wedges 1 described above, and will not be repeated here. Compared with the adhesive connection between multiple support wedges 1, the magnetic connection between multiple support wedges 1 can ensure a firm connection while making the disassembly and installation of multiple support wedges 1 more convenient and quick. Moreover, multiple support wedges 1 will not leave glue residue after disassembly, eliminating the glue removal process when multiple support wedges 1 are reused, reducing the assembly steps and assembly time of multiple support wedges 1, further shortening the assembly time of the leveling structure 100, thereby reducing the production cost of liquefied gas storage equipment.

[0067] Furthermore, the end of the second magnet 13 near the opening of the second mounting groove 1121 is not higher than the second surface 112, so as to avoid the second magnet 13 protruding from the second surface 112 and affecting the flatness of the second surface 112, thereby enabling the second surface 112 to be completely in contact with the first surface 111, ensuring the stability of the connection between the multiple support wedges 1.

[0068] Furthermore, when the end of the first magnet 12 near the opening of the first mounting groove 1111 in the plurality of support wedges 1 is N / S pole, the end of the second magnet 13 near the opening of the second mounting groove 1121 is S / N pole, so that the first surface 111 and the second surface 112 have magnetic fields with opposite directions, so that the second surface 112 of one support wedge 1 can be smoothly attracted to the first surface 111 of another support wedge 1.

[0069] As described in the above embodiments, multiple support wedges 1 are stacked along the first direction X, so that the leveling structure 100 has different heights in the first direction X. This allows multiple recesses or protrusions of varying degrees on the inner surface of the container wall 200 to be leveled into a single plane, thereby further improving the leveling effect of the leveling structure 100. A second magnet 13 is connected to the second mounting groove 1121 opened on the second surface 112 of the support body 11. The second magnet 13 attracts the first magnet 12 set on another support wedge 1. This ensures that the multiple support wedges 1 are firmly connected, while making the disassembly and installation of the multiple support wedges 1 more convenient and faster. It reduces the assembly steps and assembly time of the multiple support wedges 1, further shortening the assembly time of the leveling structure 100, thereby reducing the production cost of the liquefied gas storage equipment.

[0070] Furthermore, the end of the second magnet 13 near the opening of the second mounting groove 1121 is not higher than the second surface 112, which ensures the stability of the connection between the multiple support wedges 1. In addition, when the ends of the first magnets 12 near the opening of the first mounting groove 1111 in the multiple support wedges 1 are all N / S poles, the ends of the second magnets 13 near the opening of the second mounting groove 1121 are all S / N poles, so that the second surface 112 of one support wedge 1 can be smoothly attracted to the first surface 111 of another support wedge 1.

[0071] Furthermore, when a first magnet 12 is provided on the first surface 111 of the support body 11, and a second magnet 13 that can engage with the first magnet 12 is provided on the second surface 112 of the support body 11, multiple support wedges 1 can also be magnetically connected into a whole during transportation and storage, thereby facilitating transportation and storage. For example, when the support wedges need to be recycled and reused, the recycled support wedges 1 can be magnetically connected into a whole, thereby facilitating the storage, transportation, and eventual reuse of the recycled support wedges 1.

[0072] Furthermore, in order to further ensure the leveling effect of the leveling structure 100, the present application may be improved as follows:

[0073] In some embodiments, such as Figure 3 As shown, the support wedge 1 includes multiple first magnets 12 and multiple second magnets 13. Multiple first mounting slots 1111 are provided on the first surface 111. Multiple second mounting slots 1121 are provided on the second surface 112. The number of first magnets 12, second magnets 13, first mounting slots 1111, and second mounting slots 1121 are the same. The positions of the first mounting slots 1111 and the second mounting slots 1121 in the first direction X correspond one-to-one.

[0074] The support wedge 1 includes a plurality of first magnets 12, which can increase the connection area between the support wedge 1 and the inner surface of the container wall 200, thereby improving the stability of the connection between the support wedge 1 and the inner surface of the container wall 200. Similarly, the support wedge 1 includes a plurality of second magnets 13, which can increase the connection area between the plurality of support wedges 1, thereby improving the stability of the connection between the plurality of support wedges 1.

[0075] Accordingly, a plurality of first mounting slots 1111 are provided on the first surface 111 for mounting the plurality of first magnets 12. Similarly, a plurality of second mounting slots 1121 are provided on the second surface 112 for mounting the plurality of second magnets 13.

[0076] Furthermore, the number of first magnets 12, second magnets 13, first mounting slots 1111 and second mounting slots 1121 are the same, and the positions of the first mounting slots 1111 and second mounting slots 1121 in the first direction X correspond one-to-one, so that each second magnet 13 can be attracted and connected to a first magnet 12, thereby ensuring the stability of the connection between the multiple support wedges 1 and the inner surface of the container wall 200, that is, ensuring the stability of the connection between the leveling structure 100 and the inner surface of the container wall 200, thereby ensuring the leveling effect of the leveling structure 100.

[0077] Specifically, multiple first magnets 12 / second magnets 13 can be evenly distributed on the support 11. This reduces the volume of the first magnets 12 / second magnets 13 while ensuring connection stability, thereby reducing the input of production materials and lowering the production cost of the liquefied gas storage equipment. For example, as... Figure 3 As shown, two first magnets 12 are provided on the first surface 111 of the support body 11, and two second magnets 13 are provided on the second surface 112 of the support body 11. The two first magnets 12 and the two second magnets 13 are symmetrically arranged at both ends of the support body 11 along the length direction of the support body 11.

[0078] According to the description of the above embodiments, the support wedge 1 includes a plurality of first magnets 12 and a plurality of second magnets 13, which can increase the connection area between the plurality of support wedges 1 and the container wall 200 and reduce the volume of the first magnets 12 and the second magnets 13, thereby improving the stability of the connection between the plurality of support wedges 1 and the container wall 200, while reducing the production cost of the liquefied gas storage equipment. The number of first magnets 12, second magnets 13, first mounting grooves 1111 and second mounting grooves 1121 are the same, and the positions of the first mounting grooves 1111 and the second mounting grooves 1121 in the first direction X correspond one-to-one, so that each second magnet 13 can be attracted and connected to one first magnet 12, thereby ensuring the leveling effect of the leveling structure 100.

[0079] To further reduce the production cost of liquefied gas storage equipment, this application may also include the following design:

[0080] In some embodiments, the first mounting groove 1111 and the corresponding second mounting groove 1121 are through holes extending through the support body 11. The first magnet 12 and the second magnet 13 are both connected within the through holes.

[0081] According to the description of the above embodiments, a first mounting groove 1111 and a corresponding second mounting groove 1121 are a through hole penetrating the support body 11, and the first magnet 12 and the second magnet 13 are both connected in the through hole. This allows the second magnet 13 to correspond to and be attracted to the first magnet 12, while reducing the number of holes to be drilled on the support, thereby shortening the drilling time, saving assembly time, and thus reducing the production cost of the liquefied gas storage equipment.

[0082] To further optimize the leveling structure 100, this application may also include the following design:

[0083] In some embodiments, the support 11 may include an auxiliary structure 2. The auxiliary structure 2 may be a countersunk hole or a groove formed on the first surface 111.

[0084] Since the support body 11 is generally a smooth rectangular plywood, there is no suitable force point on the support wedge 1 for the operator to hold.

[0085] Based on this, the auxiliary structure 2 provided on the support body 11 can be used to facilitate the operator's handling of the support wedge 1. Specifically, as shown in... Figure 5 As shown, the auxiliary structure 2 is a countersunk hole or groove opened on the first surface 111, so that the operator's hand or picking tool can be inserted into the countersunk hole or groove to complete the picking or disassembly of the support wedge 1, thereby optimizing the leveling structure 100.

[0086] In some examples, when the support wedge 1 needs to be recycled, the operator's hand or a tool can be inserted into the countersunk hole or groove to remove the support wedge 1 from the container wall 200 of the liquefied gas storage device, and the recycled support wedges 1 can be connected into a whole for storage.

[0087] In other examples, when the recycled support wedge 1 needs to be reused, the operator's hand or a tool can be inserted into the countersunk hole or groove to remove the support wedge 1 from the recycled whole and lay the support wedge 1 on the container wall 200 of the liquefied gas storage device to achieve the reuse of the support wedge 1.

[0088] According to the description of the above embodiments, the auxiliary structure 2 is a countersunk hole or groove opened on the first surface 111, which makes it convenient for the operator to pick up the support wedge 1, thereby optimizing the leveling structure 100.

[0089] Furthermore, in some embodiments, an anti-slip structure may be provided in the countersunk hole or groove.

[0090] Specifically, the anti-slip structure can be a rubber sheet pasted in the countersunk hole or groove to increase the friction between the auxiliary structure 2 and the operator's hand or picking tool, so that the support wedge 1 is gripped more firmly and the support wedge 1 is prevented from loosening or slipping during the picking process.

[0091] Based on the description of the above embodiments, the anti-slip structure is used to prevent the support wedge 1 from slipping or falling from the operator's hand during the handling process, saving the operator's handling time and shortening the assembly time of the leveling structure 100, thereby further reducing the production cost of the liquefied gas storage equipment.

[0092] Furthermore, in some embodiments, locking holes and locking blocks adapted to the locking holes can be respectively provided on two opposite surfaces of the support wedge 1. The opposite surfaces are perpendicular to the first surface 111 and the second surface 112.

[0093] The snap-fit ​​hole can be a hole-like structure opened on the support wedge 1, and its shape can be a circular hole or a square hole, without specific limitation here.

[0094] The snap-fit ​​block can be a snap-fit ​​structure formed on the support wedge 1, and its shape corresponds to the shape of the snap-fit ​​hole, so that the snap-fit ​​block can snap into the snap-fit ​​hole to fit the snap-fit ​​hole. For example, when the snap-fit ​​hole is a circular hole, the snap-fit ​​block is a cylinder. When the snap-fit ​​hole is a square hole, the snap-fit ​​block is a square prism.

[0095] Specifically, multiple support wedges 1 are stacked along the first direction X to form a group of recyclable units. Multiple groups of recyclable units are then stacked perpendicular to the first direction X. Each support wedge 1 has a locking hole and a locking block on its two opposite sides perpendicular to the first direction X. This allows the locking block of a support wedge 1 in one group of recyclable units to engage with the locking hole of a support wedge 1 in another group of recyclable units, thereby connecting the two groups of recyclable units into a single unit. This reduces the storage space required for multiple support wedges 1 during recycling along the first direction X, thus optimizing the recycling and storage of the support wedges 1.

[0096] Furthermore, to reduce the maintenance cost of the leveling structure 100, in some embodiments, the first magnet 12 can be detachably connected to the first mounting groove 1111. And the second magnet 13 can be detachably connected to the second mounting groove 1121.

[0097] Based on the description of the above embodiments, the first magnet 12 is detachably connected to the first mounting groove 1111, allowing for easy replacement and maintenance. Similarly, the second magnet 13 is detachably connected to the second mounting groove 1121, allowing for easy replacement and maintenance. In summary, either the first magnet 12 or the second magnet 13 can be replaced and maintained individually, reducing the minimum maintenance unit of the leveling structure 100, lowering the maintenance cost of the leveling structure 100, and consequently reducing the production cost of the liquefied gas storage equipment.

[0098] Specifically, the detachable connection can be a snap-fit ​​connection, a threaded connection, an adhesive connection, etc., and this application does not make any specific limitation on this.

[0099] In some embodiments, the first magnet 12 and the second magnet 13 are both permanent magnets made of bonded neodymium iron boron material.

[0100] Bonded NdFeB magnets possess high toughness and mechanical strength, and are not easily brittle. Furthermore, bonded NdFeB magnets are formed by compression molding, eliminating the need for high-temperature sintering, thus reducing costs.

[0101] According to the description of the above embodiments, the first magnet 12 and the second magnet 13 are both permanent magnets made of bonded neodymium iron boron material, which makes the first magnet 12 and the second magnet 13 less brittle and reduces the production cost of the first magnet 12 and the second magnet 13, thereby reducing the production cost of the liquefied gas storage equipment.

[0102] Secondly, this application provides a liquefied gas storage device, including a container wall and a leveling structure as described in any of the above embodiments. The leveling structure is disposed between the container wall and the tank body.
