Description

Technical Field

[0001] This application relates to the technical field of storage tank containers, and particularly to a thin-film storage tank, its leveling assembly, and installation method. Background Art

[0002] During the storage and transportation of liquefied natural gas (LNG), the heat insulation performance of LNG storage tanks is crucial. Since LNG needs to be stored at extremely low temperatures (about -162°C), any heat infiltration may cause the liquefied natural gas to vaporize, resulting in increased pressure and safety risks. Therefore, LNG storage tanks usually adopt a double-layer structure, with the inner tank for storing LNG, the outer tank as a protective layer, and heat insulation modules installed between the two to maintain a low-temperature environment.

[0003] The installation quality of the heat insulation modules directly affects the heat preservation effect and safety of the storage tank. However, whether it is a marine LNG storage tank or a land-based LNG storage tank, the installation base surface (such as the metal wall of the ship's cabin or the inner wall of the concrete outer tank) often has surface unevenness problems. In marine applications, the metal cabin wall may be uneven due to welding deformation, processing errors, or long-term stress; while in land-based storage tanks, the concrete pouring process may result in a rough or locally protruding surface due to formwork deformation, shrinkage, or construction errors.

[0004] This unevenness will cause the heat insulation modules not to fit tightly with the base surface, resulting in gaps, reducing the heat insulation effect, and even causing module damage or detachment due to local stress concentration. In addition, during ship transportation, if the heat insulation modules are not installed firmly, they may also shift due to ship swaying or vibration, further exacerbating the decline in heat insulation performance and safety risks.

[0005] Currently, traditional heat insulation module installation methods usually rely on manual adjustment or gasket filling, but this method is inefficient, inaccurate, and difficult to adapt to the irregular shapes of different base surfaces. Therefore, there is an urgent need for a thin-film storage tank, its leveling assembly, and installation method to ensure that the heat insulation modules can be stably and tightly installed on various base surfaces, thereby improving the safety and heat insulation performance of LNG storage tanks. Summary of the Invention

[0006] This application provides a thin-film storage tank, its leveling assembly, and installation method to solve the current problems of concrete unevenness and low installation efficiency.

[0007] In a first aspect, the present application provides a leveling assembly for a thin-film storage tank, comprising: at least two first connection structures embedded inside the installation layer; a support body having a first surface facing the installation layer and a second surface facing away from the installation layer, the second surface facing the insulation module; a plurality of second connection structures are provided on the first surface, the number of the second connection structures is at least greater than that of the first connection structures, and the second connection structures can be cooperatively connected with the first connection structures; when the first connection structures and the second connection structures are connected, the relative distance between the first connection structures and the second connection structures can be adjusted.

[0008] Through the above solution, the precise connection between the support body and the installation layer is realized through the first connection structures embedded inside the installation layer and the second connection structures on the support body. The number of the second connection structures is more than that of the first connection structures, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The relative distance between the first connection structures and the second connection structures can be adjusted, which enables the leveling assembly to adapt to the inner wall surfaces with various flatnesses and can be finely adjusted according to the actual situation during the construction process to ensure the flatness and stability of the support body. By embedding the connection structures inside the installation layer, the connection strength between the storage tank and the wall is enhanced, and the inclination or damage after fixing the insulation module due to external forces or uneven settlement is avoided. The design of this leveling assembly simplifies the construction process, reduces the complex leveling operations in traditional construction, reduces the construction difficulty and time cost, and can achieve a firm and tight installation, thereby improving the safety and insulation performance of the LNG storage tank.

[0009] In a possible design, the area of the second surface is smaller than the area of the installation surface of the insulation module, and the first surface is parallel to the second surface.

[0010] Through the above solution, the area of the second surface being smaller than the area of the installation surface of the insulation module means that the size of the support body is relatively small, which can save materials and installation space. This compact design makes the entire leveling assembly lighter, facilitating transportation and installation, and reducing the construction difficulty and cost. Since the first surface is parallel to the second surface and the area of the second surface is smaller, the leveling assembly can be more conveniently adjusted in the horizontal or vertical direction during the installation process to ensure a tight connection between the insulation module and the storage tank. The area of the second surface of the support body is smaller than the area of the installation surface of the insulation module, but through the cooperation of a plurality of second connection structures and the first connection structures, the force can be evenly dispersed to the installation layer, avoiding local stress concentration, thereby enhancing the stability of the entire storage tank system. This design makes the installation of the support body simpler. Construction workers can quickly complete the connection between the support and the installation layer, and at the same time reduce the errors caused by improper installation. Since the first surface is parallel to the second surface and the area of the second surface is smaller, the leveling assembly can be quickly calibrated in the horizontal or vertical direction through simple tools or manual adjustment during the installation process, improving the construction efficiency.

[0011] In a possible design, the bracket body is composed of criss-crossing reinforcing ribs, forming multiple intersection points, and a second connection structure is formed at each intersection point.

[0012] Through the above solution, the design of criss-crossing reinforcing ribs can effectively disperse and bear the weight of the storage tank and the insulation module, improve the bearing capacity of the bracket, and the second connection structure at the intersection points provides multiple connection points, which can flexibly cooperate with the pre-embedded first connection structure to ensure accurate leveling of the storage tank during installation. The criss-crossing reinforcing rib structure reduces material waste while ensuring strength, and reduces manufacturing costs. The cross structure of the reinforcing ribs can effectively resist external forces, such as seismic loads or wind forces, and improve the overall seismic performance of the storage tank. The design of the bracket body composed of criss-crossing reinforcing ribs not only improves the structural stability and connection accuracy of the storage tank leveling component, but also optimizes material use and construction efficiency, with high practicality and economy.

[0013] In a possible design, the second connection structure is a threaded hole; the first connection structure includes a pre-embedded installation part and a connection bolt fixed on the pre-embedded installation part.

[0014] Through the above solution, the threaded hole is directly machined at the intersection point of the bracket body and can cooperate with the connection bolt. The pre-embedded installation part is pre-embedded inside the installation layer to ensure close bonding with the concrete. The connection bolt is fixed on the pre-embedded installation part and is used to cooperate with the threaded hole of the bracket body for connection. Through the cooperation of the bolt and the threaded hole, high-precision connection and fine adjustment can be achieved. During installation, the position of the bracket body can be adjusted as needed to ensure the levelness and verticality of the storage tank. Threaded connection has high strength and stability, can effectively bear the weight of the storage tank and the insulation module, and reduce deformation caused by external forces or uneven settlement.

[0015] In a possible design, the connection bolt is a universal joint bolt.

[0016] Through the above solution, the universal joint bolt can adapt to the angular offset between axes. Even if there is a certain angular deviation during installation, it can ensure the stability and reliability of the connection. This is particularly important for the installation of thin-film storage tanks because there may be a small angular error between the storage tank and the bracket, and the universal joint bolt can effectively compensate for these errors.

[0017] In a possible design, at least one end of the connection bolt is provided with a spherical washer.

[0018] Through the above solution, the spherical washer can create an accurate parallel contact surface between the bolt head and the nut and automatically adjust to compensate for the angular deviation between the planes. This feature is particularly applicable to the installation scenario of thin-film storage tanks because there may be minor angular errors between the storage tank and the support, and the spherical washer can effectively compensate for these errors to avoid bolt bending. The spherical washer can evenly distribute the clamping force of the bolt over the entire contact surface, thereby reducing local stress concentration. This not only improves the reliability of the connection but also reduces the fatigue of the bolt caused by uneven stress. The design of the spherical washer can prevent bolt bending, thereby reducing the possibility of bolt relaxation. In this embodiment, the spherical washer is made of high-grade alloy steel and undergoes special surface treatment to provide better protection in humid or corrosive environments.

[0019] In a possible design, the second connection structure is a snap interface; the first connection structure includes a pre-embedded snap base and a snap connector; the pre-embedded snap base includes a spherical or gimbal structure that can rotate freely within a certain angle range; the snap interface is connected to the pre-embedded snap base through a spherical snap or gimbal snap.

[0020] Through the above solution, the snap interface is designed for quick connection and separation with the snap connector, with simple operation. The pre-embedded snap base is pre-embedded inside the installation layer and adopts a spherical or gimbal structure that can rotate freely within a certain angle range, providing angle compensation ability. The snap connector: is fixed on the pre-embedded snap base and is used to cooperate with the second connection structure (snap interface) to achieve quick connection. The snap interface is connected to the pre-embedded snap base through a spherical snap or gimbal snap. This connection method allows for angle adjustment during installation to ensure precise alignment between the storage tank and the support. The pre-embedded snap base with a spherical or gimbal structure can rotate freely within a certain angle range to adapt to the possible angular deviation during installation and ensure precise alignment between the storage tank and the support. This design combines the snap interface with the pre-embedded snap base with a spherical or gimbal structure to achieve the flexibility of angle adjustment, the convenience of quick installation and disassembly, the reliability of structural strength and stability, and the convenience of maintenance and replacement. It is used for the installation of the thin-film storage tank system and can significantly improve the overall performance and construction efficiency of the system.

[0021] In a possible design, multiple snap positions are designed inside the snap interface or on the snap connector, and the snap interface and the snap connector can achieve fixation at different gears to realize height or angle adjustment.

[0022] Through the above solution, multiple snap positions are designed inside the snap interface for realizing height or angle adjustment at different levels. Combined with the pre-embedded snap base with a spherical or gimbal structure, it can significantly improve the overall performance and construction efficiency of the system.

[0023] In a possible design, the end of the first connection structure can pass through the support body and form a fixed connection with the thermal insulation module.

[0024] Through the above solution, the end of the first connection structure is designed to be able to pass through the support body and form a fixed connection with the thermal insulation module, which can ensure the stability of the fixation of the thermal insulation module.

[0025] In a possible design, it further includes at least one gasket, and the gasket is sleeved on the first connection structure and / or the second connection structure; the gasket is arranged between the support body and the installation layer and / or between the thermal insulation modules.

[0026] Through the above solution, the gasket can be used to adjust the gap between the first connection structure and the second connection structure, ensure the tightness of the connection, and prevent loosening. It can make the force on the connection structure more uniform, reduce local stress concentration, and improve the stability of the connection; the gasket arranged between the support body and the installation layer and / or between the thermal insulation modules can better achieve leveling.

[0027] In a possible design, it further includes a resin mortar layer, and the resin mortar layer wraps the support body.

[0028] Through the above solution, the resin mortar layer can tightly bond each part of the support body together to form a whole, improving the structural strength and stability of the support. The wrapping of the resin mortar layer can reduce the loosening and deformation of the support body caused by vibration or external forces during use. The resin mortar layer can fill the tiny gaps and unevenness on the surface of the support body to form a smooth surface, providing a better foundation for the installation of the thermal insulation module.

[0029] In a second aspect, the present application provides a thin-film storage tank, including an installation layer, a thermal insulation module, and a leveling assembly according to any one of the above, the leveling assembly is fixed on the installation layer, and the thermal insulation module is fixed on the leveling assembly.

[0030] For the thin-film storage tank provided in the above second aspect and each possible design of the second aspect, the beneficial effects can refer to the beneficial effects brought by the above first aspect and each possible implementation manner of the first aspect, which will not be elaborated here.

[0031] In a third aspect, the present application provides an installation method for a thin-film storage tank, including the steps of: installing the first connection structure on the installation layer; providing a leveling assembly according to any one of the above, connecting the second connection structure and the first connection structure, and adjusting the distance between the second connection structure and the first connection structure according to the surface condition of the installation layer to make the surfaces between the support bodies parallel; covering the thermal insulation module on the support body and fixedly connecting the thermal insulation module through the first connection structure.

[0032] In the installation method of the thin-film storage tank provided in the above-mentioned second aspect and each possible design of the second aspect, according to the surface condition of the installation layer, the main body of the installation bracket is installed, and the distance between the second connection structure and the first connection structure is adjusted so that the main body of the bracket meets the flatness requirements for the installation of the thermal insulation module. The main body of the installation bracket can be quickly leveled, so that the thermal insulation module can be quickly installed, improving the installation efficiency of the thin-film storage tank.

[0033] In a possible design, before covering the thermal insulation module on the main body of the bracket, the method further includes the step of pouring resin mortar into the main body of the bracket to form a resin mortar layer.

[0034] Through the above solution, resin mortar is poured into the main body of the bracket, so that the main body of the bracket is buried inside the resin mortar layer. The resin mortar layer can further play a role in leveling and stabilizing, and also provides a better adhesion foundation for the thermal insulation module, enhancing the bonding force between the thermal insulation module and the main body of the bracket.

[0054] As can be seen from the background art, during the manufacturing process of a thin-film storage tank at present, the stability and heat insulation effect of the heat insulation module 300 are very important for the quality of the storage tank. However, the installation of the heat insulation module 300 usually requires a flat inner wall surface. Otherwise, it will lead to difficulties in installation, poor heat insulation effect, and even problems such as detachment.

[0055] In view of this, the embodiments of the present application provide a thin-film storage tank, its leveling assembly and installation method. In the leveling assembly of the thin-film storage tank, through the first connection structure 120 embedded inside the installation layer 100 and the second connection structure 210 on the support body 200, the precise connection between the support body 200 and the installation layer 100 is achieved. The number of the second connection structures 210 is more than that of the first connection structures 120, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The second connection structure 210 can be selected to be connected with the corresponding first connection structure 120 according to the actual situation of the concrete wall surface, so as to achieve a better leveling effect. The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted, which enables the leveling assembly to adapt to the inner wall surfaces with various flatnesses, and at the same time can be finely adjusted according to the actual situation during the construction process to ensure the flatness and stability of the support body 200. The design of this leveling assembly simplifies the construction process, reduces the complex leveling operations in traditional construction, reduces the construction difficulty and time cost, and improves the manufacturing efficiency.

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0057] Figure 1 It is a schematic overall view of the installation of the adiabatic module 300 provided in this embodiment on the inner wall. Please refer to Figure 1 In this embodiment, the leveling assembly of the thin-film storage tank includes: at least two first connection structures 120 embedded inside the installation layer 100 and the support body 200. The support body 200 has a first surface facing the installation layer 100 and a second surface facing away from the installation layer 100, and the second surface faces the adiabatic module 300; there are a plurality of second connection structures 210 on the first surface, and the number of the second connection structures 210 is at least greater than that of the first connection structures 120, and the second connection structures 210 can be connected in cooperation with the first connection structures 120; when the first connection structure 120 and the second connection structure 210 are connected, the relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted.

[0058] The installation layer can be the concrete layer of a land storage tank or the metal wall of the cabin of an LNG ship.

[0059] The support body 200 is fixed on the installation layer 100. By adjusting the relative position between the support body 200 and the installation layer 100, a flat attachment and fixing surface can be provided for the adiabatic module 300.

[0060] In some embodiments, the contour of the support body 200 can be of any shape, for example, it can be square or circular. It can be understood that the shape of the first surface and / or the second surface is square or circular.

[0061] The material of the adiabatic module 300 consists of adiabatic materials such as polystyrene foam and reinforced polyurethane foam, as well as plywood on both sides of the adiabatic material, and its structure is similar to a "sandwich" structure. The plywood can play the roles of connection, fixation, and support, improving the strength of the adiabatic module 300 and avoiding breakage.

[0062] Figure 2 Schematic diagram of the first connection structure 120 provided in this embodiment and fixed on the installation layer 100. Please refer to Figure 2 , the quantity and position of the first connection structure 120 should be flexibly determined according to the situation of the concrete inner wall, and can be set to 2, 3, or 4. The more the number of the first connection structures 120, the tighter the connection between the support main body 200 and the installation layer 100. However, too many first connection structures 120 will affect the adiabatic performance of the thin-film storage tank and reduce the subsequent installation speed. Therefore, in this embodiment, the number of the first connection structures 120 does not exceed 4.

[0063] Through the above solution, the first connection structure 120 embedded inside the installation layer 100 and the second connection structure 210 on the support main body 200 achieve the precise connection between the support main body 200 and the installation layer 100. The number of the second connection structures 210 is more than that of the first connection structures 120, which can provide more connection points, thereby improving the installation accuracy of the storage tank. The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted, which enables the leveling component to adapt to the inner wall surfaces with various flatness degrees, and at the same time can be finely adjusted according to the actual situation during the construction process to ensure the flatness and stability of the support main body 200. By embedding the connection structure inside the installation layer 100, the connection strength between the storage tank and the wall is enhanced, and the inclination or damage after fixing the adiabatic module 300 caused by external force or uneven settlement is avoided. The design of this leveling component simplifies the construction process, reduces the complex leveling operations in traditional construction, reduces the construction difficulty and time cost, and can achieve a stable and tight installation, thereby improving the safety and adiabatic performance of the LNG storage tank.

[0064] In this embodiment, the area of the second surface is smaller than the area of the installation surface of the adiabatic module 300, which means that the size of the support main body 200 is relatively small, which can save materials and installation space. This compact design makes the entire leveling component lighter, facilitating transportation and installation, and reducing the construction difficulty and cost.

[0065] In this embodiment, the first surface is parallel to the second surface, that is, the support main body 200 is a flat structure. In this way, by adjusting the relative distance between the first connection structure 120 and the second connection structure 210, the adjustment of the support main body 200 in the horizontal or vertical direction can be realized, so as to ensure the tight connection of the adiabatic module 300.

[0066] Through the cooperation of multiple second connection structures 210 with the first connection structure 120, the force can be evenly dispersed onto the installation layer 100, avoiding local stress concentration, thereby enhancing the stability of the entire storage tank system. This design makes the installation of the bracket body 200 simpler. Construction workers can quickly complete the connection between the bracket and the installation layer 100, while reducing errors caused by improper installation. Since the first surface is parallel to the second surface and the area of the second surface is small, the leveling component can be quickly calibrated in the horizontal or vertical direction through simple tools or manual adjustment during the installation process, improving the construction efficiency.

[0067] Figure 3 This is a schematic structural diagram of the bracket body 200 provided in an embodiment of the present application. Figure 4 This is a schematic structural diagram of the bracket body 200 provided in another embodiment of the present application. Please refer to Figure 3 and Figure 4 , the bracket body 200 is composed of crisscrossing reinforcing ribs, forming multiple intersection points, and a second connection structure 210 is formed at each intersection point.

[0068] Such as Figure 3 the crisscrossing reinforcing ribs in can be square bars, or as Figure 4 in, the crisscrossing reinforcing ribs are round bars. The diameter of the round bar reinforcing ribs or the width of the square bar reinforcing ribs does not exceed 1 cm.

[0069] Through the above solution, the design of the crisscrossing reinforcing ribs can effectively disperse and bear the weight of the storage tank and the insulation module 300, improving the bearing capacity of the bracket. The second connection structure 210 at the intersection points provides multiple connection points, which can flexibly cooperate with the pre-embedded first connection structure 120 to ensure precise leveling of the storage tank during installation. The crisscrossing reinforcing rib structure reduces material waste while ensuring strength, reducing manufacturing costs. The cross structure of the reinforcing ribs can effectively resist external forces, such as seismic loads or wind forces, improving the overall seismic performance of the storage tank. The design of the bracket body 200 composed of crisscrossing reinforcing ribs not only improves the structural stability and connection accuracy of the leveling component of the storage tank, but also optimizes material usage and construction efficiency, with high practicality and economy. And, since the first surface and the second surface are parallel, a second connection structure 210 is formed inside each intersection point. When the insulation module 300 directly contacts the bracket body 200, it makes the insulation module 300 have a relatively flat attachment surface, which can improve the installation stability of the insulation module 300.

[0070] The relative distance between the first connection structure 120 and the second connection structure 210 can be adjusted by setting gaskets 130 and different connection structures.

[0071] Figure 5Schematic diagram of the gasket being respectively disposed between the bracket main body and the installation layer and between the bracket main body and the thermal insulation module. Figure 6 Schematic diagram of the gasket being only disposed between the bracket main body and the installation layer. Please refer to Figure 5 and Figure 6 , in this embodiment, it includes at least one gasket 130, and the gasket 130 is sleeved on the first connection structure 120 and / or the second connection structure 210; the gasket 130 is disposed between the bracket main body 200 and the installation layer 100 and / or between the thermal insulation modules 300.

[0072] The material of the gasket 130 can be a non-metal gasket, such as rubber, polytetrafluoroethylene, etc. The non-metal gasket has good corrosion resistance, can protect the connection structure from chemical erosion, and extend the service life.

[0073] Through the above solution, the gasket 130 can be used to adjust or assist in adjusting the distance between the first connection structure 120 and the second connection structure 210, that is, it can be used to adjust the gap between the first connection structure 120 and the second connection structure 210, and can ensure the tightness of the connection and prevent loosening. It can make the force on the connection structure more uniform, reduce local stress concentration, and improve the stability of the connection. When needed, the use of the gasket 130 is simple and convenient, and the construction personnel can quickly complete the installation without complex tools or operations.

[0074] In some embodiments, if after the bracket main body 200 is fixed on the installation layer 100 and leveled, when installing the thermal insulation module 300 subsequently, it is found that the bracket main body 200 does not meet the surface flatness requirements for the installation of the thermal insulation module 300, a gasket 130 can also be set between the bracket main body 200 and the thermal insulation module 300 as needed (such as Figure 5 shown) to further level, so as to meet the installation requirements of the thermal insulation module 300. Furthermore, it can improve the installation effect of the storage tank and ensure the stability of the storage tank.

[0075] In some embodiments, a plurality of second connection structures 210 are correspondingly designed on the main body structure.

[0076] In this embodiment, the second connection structure 210 may be a threaded hole. The threaded hole is directly machined at the intersection position of the bracket body 200, can cooperate with the connection bolt, and can reasonably utilize the space area, so that the number of the second connection structures 210 is as large as possible. In this way, according to the surface condition of the concrete inner wall, the second connection structure 210 at a suitable position can be selected to be connected with the first connection structure 120. Since the number of the second connection structures 210 is large enough, the accuracy requirement for the embedded installation of the first connection structure 120 is reduced (any first connection structure 120 can find a suitable second connection structure 210 for corresponding connection). Thus, the installation position of the first connection structure 120 is relatively flexible, the calibration time can be reduced, and the installation efficiency is improved.

[0077] In some embodiments, the first connection structure 120 includes an embedded installation part 110 and a connection bolt fixed on the embedded installation part 110.

[0078] Through the above solution, the embedded installation part 110 can be pre-buried inside the installation layer 100 by an anchoring method to ensure a tight combination with the concrete. The connection bolt is fixed on the embedded installation part 110 and is used for cooperating and connecting with the threaded hole of the bracket body 200. Through the cooperation of the bolt and the threaded hole, high-precision connection and fine adjustment can be achieved. During the installation process, the position of the bracket body 200 can be adjusted as needed to ensure the levelness and verticality of the storage tank. The threaded connection has high strength and stability, can effectively bear the weight of the storage tank and the insulation module 300, and reduce the deformation caused by external force or uneven settlement.

[0079] In this embodiment, the connection bolt is a universal joint bolt.

[0080] Through the above solution, the universal joint bolt can adapt to the angular offset between the axes. Even if there is a certain angular deviation during the installation process, the stability and reliability of the connection can be ensured. This is particularly important for the installation of the thin-film storage tank because there may be a small angular error between the storage tank and the bracket, and the universal joint bolt can effectively compensate for these errors.

[0081] In this embodiment, spherical washers are provided at at least one end of the connection bolt.

[0082] Through the above solution, the spherical washer can create an accurate parallel contact surface between the bolt head and the nut and automatically adjust to compensate for the angular deviation between the planes. This characteristic is particularly applicable to the installation scenario of thin-film storage tanks because there may be minor angular errors between the storage tank and the support, and the spherical washer can effectively compensate for these errors to avoid bolt bending. The spherical washer can evenly distribute the clamping force of the bolt across the entire contact surface, thereby reducing local stress concentration. This not only improves the reliability of the connection but also reduces the fatigue of the bolt caused by uneven stress. The design of the spherical washer can prevent bolt bending, thereby reducing the possibility of bolt relaxation. In this embodiment, the spherical washer is made of high-grade alloy steel and undergoes special surface treatment, capable of providing better protection in humid or corrosive environments.

[0083] The process of installing the support main body 200 through the above-mentioned embedded mounting frame can be as follows: First, position the support main body 200 at the corresponding position, then pre-connect the threaded holes and connecting bolts at appropriate positions, and then adjust the distance between the threaded holes and the universal joint bolts according to the need for flatness. When adjusting the distance between the threaded holes and the connecting bolts, the angle of the universal joint bolts can be appropriately adjusted according to the situation, so as to ensure the flatness of the support main body 200 through fine-tuning. Finally, fix the universal joint bolts to ensure the stability of the mounting bracket.

[0084] In this embodiment, the second connection structure 210 is a snap interface; the first connection structure 120 includes an embedded snap base and a snap connector; the embedded snap base includes a spherical or universal joint structure and can rotate freely within a certain angle range; the snap interface is connected to the embedded snap base through a spherical snap or a universal joint snap.

[0085] Through the above solution, the snap interface is designed for quick connection and separation with the snap connector, with simple operation. The embedded snap base is embedded inside the installation layer 100, adopts a spherical or universal joint structure, and can rotate freely within a certain angle range, providing angle compensation ability. The snap connector: is fixed on the embedded snap base and is used to cooperate with the second connection structure 210 (snap interface) to achieve quick connection. The snap interface is connected to the embedded snap base through a spherical snap or a universal joint snap. This connection method allows for angle adjustment during installation to ensure precise alignment between the storage tank and the support. The embedded snap base with a spherical or universal joint structure can rotate freely within a certain angle range to adapt to the possible angle deviation during installation and ensure precise alignment between the storage tank and the support. This design combines the snap interface with the embedded snap base of a spherical or universal joint structure to achieve the flexibility of angle adjustment, the convenience of quick installation and disassembly, the reliability of structural strength and stability, and the convenience of maintenance and replacement. It is used for the installation of the thin-film storage tank system and can significantly improve the overall performance and construction efficiency of the system.

[0086] In this embodiment, multiple snap positions are designed inside the snap interface or on the snap connector. The snap interface and the snap connector can achieve fixation at different gears, realizing height or angle adjustment.

[0087] When the snap interface and the snap connector achieve fixation at any gear, they are locked and will no longer rotate or move.

[0088] Through the above solution, multiple snap positions are designed inside the snap interface for realizing adjustment of different heights or angles. Combined with the embedded snap base with a spherical or gimbal structure, the overall performance and construction efficiency of the system can be significantly improved.

[0089] The process of installing the main body 200 of the mounting bracket through the above-mentioned embedded mounting frame can be as follows: First, align the main body 200 of the bracket at the corresponding position, then pre-connect the snap interface and the snap connector at an appropriate position, and then adjust the distance between the snap interface and the snap connector according to the need for flatness. Or the angle of the spherical snap or gimbal snap can also be adjusted to achieve fine adjustment. When adjusting the distance between the snap interface and the snap connector, the snap positions inside the snap interface can be appropriately adjusted according to the situation to ensure the flatness of the main body 200 of the bracket and guarantee the stability of the installed bracket.

[0090] Please continue to refer to Figure 5 and Figure 6 In this embodiment, the end of the first connection structure 120 can pass through the main body 200 of the bracket and form a fixed connection with the heat insulation module 300.

[0091] Through the above solution, the end of the first connection structure 120 is designed to be able to pass through the main body 200 of the bracket and form a fixed connection with the heat insulation module 300, which can ensure the stability of the fixation of the heat insulation module 300.

[0093] After the installation of the main body 200 of the bracket is completed, the resin mastic layer 400 can be formed inside and on the surface of the main body 200 of the bracket by pouring, spraying or brushing.

[0094] Through the above solution, the resin mastic layer 400 can tightly bond various parts of the support body 200 together to form an integral whole, improving the structural strength and stability of the support. The wrapping of the resin mastic layer 400 can reduce the looseness and deformation of the support body 200 caused by vibration or external forces during use. The resin mastic layer 400 can fill the tiny gaps and unevenness on the surface of the support body 200 to form a smooth surface, providing a better foundation for the installation of the insulation module 300 and making the installation of the insulation module 300 more stable.
