Description

Technical Field

[0001] The present application relates to the field of fluid transportation technology, and in particular to a film enclosure system for a cryogenic storage tank and fluid transportation equipment. Background Art

[0002] A cryogenic storage tank is a container used to store cryogenic liquids (such as liquid natural gas, liquid oxygen, liquid nitrogen, etc.). Its containment system refers to the shell and insulation layer of the tank. The design and material selection of these structures must be able to adapt to and maintain the low temperature environment inside the tank to prevent heat from entering and causing the liquid to heat up, thereby ensuring the stability and safety of the stored substances.

[0003] The existing enclosure system has a limited maximum thickness due to production process limitations. Therefore, a bridge block is set between two adjacent insulation modules.

[0004] However, the connection of existing bridge blocks is unstable and easily produces a cold bridge effect, which reduces the thermal insulation effect. Summary of the invention

[0005] The present application provides a film enclosure system and fluid transport equipment for a cryogenic storage tank, which can break through the thickness limitation of the existing insulation module of the bridging block, and through the setting of the bridging block, can solve the problem of cold leakage in the gap between two adjacent insulation modules.

[0006] In a first aspect, the present application provides a film enclosure system for a cryogenic storage tank. The enclosure system is installed on the inner wall of the cryogenic storage tank. The enclosure system includes a plurality of thermal insulation modules and bridging blocks.

[0007] A plurality of heat insulation modules are installed on the inner wall of the storage tank, the plurality of heat insulation modules are spliced ​​and cover at least part of the inner wall of the storage tank, and an assembly groove is provided at the splicing position of the heat insulation modules. A bridge block is installed in the assembly groove, and the bridge block can connect two adjacent heat insulation modules together.

[0008] The setting of the bridging block can easily increase the thickness of the entire insulation module. Adding a bridging block can solve the problem of the maximum thickness of the insulation module of 350mm in the prior art (such as the insulation module whose insulation material is polyurethane). Moreover, through the setting of the bridging block, the problem of cold leakage in the gap between two adjacent insulation modules can be solved. In other words, the film enclosure system of the low-temperature storage tank in the present application can break through the thickness limit of the existing insulation module of the bridging block, and through the setting of the bridging block, the problem of cold leakage in the gap between two adjacent insulation modules can be solved.

[0009] Specifically, the containment system is designed and installed on the inner wall of the cryogenic storage tank to provide effective thermal insulation protection.

[0010] The insulation modules are mounted on the inner wall of the tank and cover at least part of the inner wall of the tank by precise splicing. Assembly grooves are provided at the splicing positions of the insulation modules to ensure that the modules can be tightly connected together.

[0011] The bridging blocks are installed in these assembly grooves. The function of the bridging blocks is to firmly connect two adjacent insulation modules to form a continuous insulation layer. This design not only increases the overall thickness of the entire insulation system, but also effectively overcomes the thickness limitations of the insulation modules in the prior art by increasing the number of bridging blocks. For example, when polyurethane is used as the insulation material, the maximum thickness of the traditional insulation module is usually limited to 350mm. With the setting of the bridging blocks, insulation modules of greater thickness can be set, such as insulation modules of 400mm, 500mm, 600mm, etc. The specific thickness can be set as needed and is not limited to the above examples.

[0012] The introduction of the bridge block also solves another technical problem, which is how to effectively reduce or eliminate the gaps that may appear between two adjacent insulation modules, thereby avoiding the leakage of cold air. Through this design, the insulation performance of the cryogenic storage tank can be significantly improved, ensuring that the low-temperature environment inside the tank is better maintained.

[0013] Furthermore, the design of the bridge block not only improves the splicing flexibility of the insulation module, but also significantly enhances the overall structural stability of the enclosure system. Specifically, the material of the bridge block can be the same or similar to that of the insulation module. The bridge block can be used to block the gap between two adjacent insulation modules. The bridge block with insulation performance can ensure the insulation effect of the entire enclosure system.

[0014] In addition, a sealing structure can be set on the bridge block. The sealing structure needs to have a certain elastic deformation margin, which can ensure a certain sealing effect before and after deformation to improve the thermal insulation effect. For example, an elastic sealing strip or a flexible sealant can be used to form an effective seal at the joint of the thermal insulation module to prevent cold leakage and further improve the thermal insulation effect of the enclosure system. The sealing structure can also be omitted and can be set according to specific needs.

[0015] The bridging block may also be equipped with a quick connection mechanism, such as a snap, bolt or threaded connection, to facilitate the rapid installation and removal of the insulation module, thereby simplifying the maintenance and replacement operations of the enclosure system.

[0016] In addition, the design of the bridge block also enhances the structural stability of the containment system, making the connection between the insulation modules more secure and reducing the impact of thermal stress caused by temperature changes on the containment system. In some preferred examples, the bridge block is made of a material compatible with the insulation module to ensure good thermal conduction isolation while maintaining the integrity and strength of the structure. The combined use of the insulation module and the bridge block not only improves the thermal insulation performance of the cryogenic storage tank, but also effectively extends the service life of the storage tank and reduces maintenance costs.

[0017] In some examples, the bridging block is fixedly connected to the inner wall of the assembly groove, and a deformation margin is provided at the fixed connection position.

[0018] The above-mentioned design allows the bridge block to have a certain degree of adaptability during the installation process, and ensures a tight fit between the bridge block and the assembly slot even when there is a certain manufacturing error or installation error in the size of the assembly slot. The setting of the deformation allowance not only improves the convenience of installation, but also enhances the stability and reliability of the entire containment system. In addition, this design also helps to reduce the structural stress caused by temperature changes or changes in pressure inside the tank, further extending the service life of the containment system.

[0019] In some examples, a side of the thermal insulation module close to the inner wall of the storage tank is a fixed side, and the fixed side is fixed to the inner wall of the storage tank by at least one of riveting, bonding, welding, magnetism, and clamping.

[0020] The selection of these fixing methods is intended to ensure that the connection between the insulation module and the inner wall of the tank is both firm and efficient. Riveting and welding provide a strong mechanical connection that can withstand greater stress or pressure, ensuring that the insulation module will not fall off due to external factors. Adhesive and magnetic methods provide more flexible installation options, especially when the insulation module needs to be installed or replaced quickly, these two methods can significantly improve work efficiency. The snap-on method combines the advantages of firmness and convenience, ensuring the stability of the connection while facilitating disassembly and maintenance.

[0021] In some examples, a bonding structure is provided between the fixed side and the inner wall of the tank, and expansion studs are provided on the inner wall of the tank. The expansion studs penetrate part of the insulation module and are locked with the insulation module by nuts.

[0022] The above-mentioned design of composite installation of the two fixing methods not only enhances the connection strength between the insulation module and the inner wall of the tank, but also provides an additional insulation layer. The bonding structure can also have a certain insulation effect, further improving the insulation effect. The use of expansion studs allows the insulation module to be fine-tuned during installation to ensure better fit with the inner wall of the tank, reducing heat leakage caused by excessive installation errors.

[0023] In some examples, the bonding structure includes a plurality of bonding sub-bodies spaced apart from each other, and depending on the shape of the inner wall of the storage tank, the thickness of the bonding sub-bodies at different positions are at least partially the same, and / or the thickness of the bonding sub-bodies at different bonding positions are at least partially the same.

[0024] The above-mentioned design enables the bonding structure to better adapt to the complex shape of the inner wall of the tank, ensuring a close fit between the thermal insulation module and the inner wall of the tank. By adjusting the thickness and distribution of the bonding sub-body, the thermal insulation effect can be further optimized and heat leakage can be reduced. At the same time, the spacing of the bonding sub-body can also provide a certain degree of elasticity, so that the thermal insulation module can better adapt to the slight deformation of the inner wall of the tank during installation and use, thereby enhancing the stability and durability of the enclosure system. In addition, the design of this bonding structure also simplifies the installation process, improves installation efficiency, and reduces installation costs.

[0025] In some examples, a reserved hole adapted to the expansion stud is provided on the thermal insulation module, and a diameter of the reserved hole is smaller than a diameter of the expansion stud and smaller than a diameter of a circumscribed circle of the nut.

[0026] The above-mentioned design enables the expansion studs to firmly fix the insulation module to the inner wall of the tank after passing through the reserved holes and tightening the nuts. The close fit between the reserved holes and the expansion studs effectively prevents the insulation module from loosening and falling off during installation and use, further enhancing the stability and safety of the containment system. At the same time, the provision of the reserved holes also simplifies the installation process, improves the installation efficiency, and makes the installation of the insulation module more convenient and quick. In addition, the adaptation design of the reserved holes and the expansion studs also enables the insulation module to adapt to expansion studs of different specifications and sizes, improving the flexibility and versatility of the containment system.

[0027] In some examples, the insulation module includes a first mounting plate, an insulation body, and a second mounting plate.

[0028] The first assembly plate is connected to the inner wall of the storage tank, and the fixed side is arranged on the first assembly plate.

[0029] The heat insulating body is connected to the first assembly plate and is located at a side of the first assembly plate away from the inner wall of the storage tank.

[0030] The second mounting plate is connected to the heat insulation body and is located at a side of the heat insulation body away from the first mounting plate.

[0031] The above structural design makes the insulation module have better layering and stability. The firm connection between the first assembly plate and the inner wall of the tank ensures that the insulation module can fit tightly on the inner wall of the tank, effectively preventing the transfer and leakage of heat. As the core part of the insulation module, the insulation body has excellent insulation performance, which can significantly reduce the temperature difference between the inner and outer walls of the tank and improve the insulation effect of the tank. The second assembly plate plays a role of further protection and fixation, making the insulation module more stable and reliable during installation and use. In addition, this layered design also facilitates the maintenance and replacement of the insulation module. When the insulation body is damaged or aged, only the corresponding part needs to be replaced, without the need for overall replacement, which reduces maintenance costs.

[0032] In some examples, the insulation body includes a first body and a second body, a first side of the first body is connected to a first assembly plate, a portion of the second side of the first body is connected to a first side of the second body, a portion of the second side of the first body is connected to a second assembly plate, and a second side of the second body is connected to the second assembly plate.

[0033] An avoidance groove is arranged at the edge of the heat insulation body. When two heat insulation modules are spliced ​​together, the two avoidance grooves are spliced ​​together to form an assembly groove.

[0034] The above design not only enhances the structural strength of the insulation body, but also improves the assembly flexibility and sealing between the insulation modules. The combination of the first body and the second body enables the insulation body to better adapt to the inner walls of tanks of different shapes and sizes while maintaining excellent insulation performance, ensuring the uniformity and consistency of the insulation effect.

[0035] Part of the second side of the first body is connected to the first side of the second body, while the other part is connected to the second assembly board. Such a layout optimizes the heat transfer path and reduces the risk of heat leakage.

[0036] In some examples, the second assembly plate includes a second assembly main plate and a second assembly sub-plate, the second assembly main plate is disposed on a side of the second body facing away from the first body, and the second assembly sub-plate is disposed in the avoidance groove.

[0037] The second assembly main board is the main connection component. It is firmly fixed to the outside of the second main body, providing reliable support for the insulation module. The second assembly sub-board is embedded in the avoidance groove, which not only enhances the connection strength between the insulation modules, but also ensures the flatness of the joints. The second assembly sub-board can be more stably connected to the bridge block to seal the gap between the two insulation modules. This design enables the insulation module to better cooperate with the bridge block during splicing, thereby forming a tighter insulation layer, effectively preventing heat transfer and improving the thermal insulation performance of the entire enclosure system. In addition, the close fit between the second assembly sub-board and the avoidance groove also reduces errors in the assembly process and improves construction accuracy and efficiency.

[0038] In some examples, at least one first mounting seat is disposed on the second assembly sub-plate, and each first mounting seat is disposed on a first assembly stud, which passes through the bridging block and is anchored to the bridging block.

[0039] The above design enables the second assembly sub-plate and the bridge block to be firmly connected together, further enhancing the structural stability and thermal insulation effect of the entire enclosure system. The first mounting seat is used as a connection point. The reasonable layout of its position and number can ensure that the thermal insulation module is evenly stressed during splicing, avoiding structural damage caused by stress concentration. At the same time, the first assembly stud runs through the bridge block and is anchored to the bridge block. This connection method is not only simple and reliable, but also can effectively resist the erosion of the external environment, extending the service life of the enclosure system.

[0040] In some examples, the projection positions of the first assembly stud and the expansion stud on the second assembly secondary plate are staggered.

[0041] This setting can avoid the formation of cold bridges after connecting multiple insulation modules and improve the insulation effect.

[0042] In addition, by staggering the positions of the first assembly studs and the expansion studs, the stress caused by assembly can be effectively dispersed, further enhancing the structural stability of the insulation module. In the actual application of cryogenic storage tanks, this design can better adapt to various complex environments and working conditions, ensuring the long-term reliable operation of the enclosure system. At the same time, this staggered layout also provides more flexibility for the assembly of the insulation module, making the installation process more efficient and convenient.

[0043] In some examples, there is a gap between two adjacent thermal insulation modules, and the spacing between different positions of the gap is always equal, and the gap between two adjacent thermal insulation modules can be filled with thermal insulation material.

[0044] The above-mentioned uniform gap design further optimizes the performance of the enclosure system. By ensuring that the gaps between adjacent insulation modules are consistent at all locations, the thermal bridge effect can be effectively avoided, heat transfer can be reduced, and the insulation effect of the entire cryogenic storage tank can be improved. In addition, uniform gaps also help maintain the stability of the temperature field inside the enclosure system and reduce temperature fluctuations, which is particularly important for storing temperature-sensitive media. At the same time, this design also simplifies the installation process, allowing workers to complete the splicing of insulation modules more quickly and accurately, improving construction efficiency and quality.

[0045] In some examples, the enclosure system also includes an insulation corner module, which includes a first bending portion and a second bending portion, the first bending portion and the second bending portion are arranged at an angle, the insulation corner module is arranged adjacent to the insulation module, and the connection method is the same as the connection method between two adjacent insulation modules.

[0046] The design of the above-mentioned insulating corner module enhances the thermal insulation performance of the enclosure system in the corner area. The angle setting of the first bend and the second bend can be adjusted according to specific needs to adapt to corner areas of different angles, thereby ensuring the integrity and continuity of the enclosure system. By connecting the insulating corner module with the insulating module in the same way, it not only simplifies the installation process, but also ensures the stability and reliability of the entire enclosure system structure. In addition, the use of the insulating corner module also effectively reduces the heat loss caused by insufficient insulation in the corner area, further improving the insulation effect and energy efficiency of the cryogenic storage tank.

[0047] In some examples, the containment system further includes a shielding module connected to the thermal insulation module.

[0048] At least one second mounting seat is arranged on the second mounting plate, and each second mounting seat is arranged with a second mounting stud, which is connected to the shielding module.

[0049] The design of the above-mentioned shielding module enhances the electromagnetic shielding performance of the enclosure system and effectively prevents the influence of external electromagnetic interference on the interior of the cryogenic storage tank. The connection method between the shielding module and the thermal insulation module ensures the stability of the structure and is also easy to install and maintain. The second mounting seat and the second assembly stud design on the second assembly plate provide a reliable installation point for the shielding module and ensure the close connection between the shielding module and other parts of the enclosure system. This design not only improves the overall performance of the enclosure system, but also provides a strong guarantee for the safe operation of the cryogenic storage tank.

[0050] In some examples, the shielding module includes a first shielding layer, a second shielding layer, and a third assembly board, the first shielding layer is spaced apart from the second shielding layer, and the third assembly board is located between the first shielding layer and the second shielding layer.

[0051] The design of the shielding module includes three main parts, namely the first shielding layer, the second shielding layer and the third assembly plate. The first shielding layer is set to maintain a certain spacing distance from the second shielding layer, and the third assembly plate is cleverly placed between the first shielding layer and the second shielding layer. Such a structural design is intended to achieve a more effective shielding effect.

[0052] The spacing between the first shielding layer and the second shielding layer helps to reduce the capacitive coupling effect between the shielding layers, thereby reducing the penetration of electromagnetic waves. The third assembly board serves as a connection and support structure, which can enhance the mechanical strength of the shielding module.

[0053] In some examples, the second assembly stud passes through the first shielding layer and is connected to the third assembly board; and / or, the first shielding layer is provided with a third assembly stud, and the third assembly stud is connected to the third assembly board.

[0054] The above design not only further enhances the structural stability of the enclosure system, but also optimizes the path of electromagnetic shielding. Specifically, the second assembly stud penetrates the first shielding layer and is connected to the third assembly plate, forming a tighter assembly structure and reducing the possibility of electromagnetic leakage.

[0055] In some examples, a third mounting seat is disposed on a side of the third assembly board facing away from the first shielding layer, and the second shielding layer is fixedly connected to the third mounting seat.

[0056] The above design details further strengthen the overall structure of the enclosure system. The third mounting seat set on the third assembly plate provides a stable support point for the fixed connection of the second shielding layer. Through precise assembly technology, the second shielding layer is closely connected to the third mounting seat to form a seamless electromagnetic shielding network. This design not only enhances the structural strength of the enclosure system, but also optimizes the electromagnetic shielding effect, so that the entire system can show higher stability and reliability when facing complex electromagnetic environments. In addition, this design also facilitates subsequent maintenance and overhaul work, reducing the system's operation and maintenance costs.

[0057] In some examples, the third mounting seat is a metal piece and is embedded in the third assembly board, and the second shielding layer is welded to the third mounting seat.

[0058] The above-mentioned combination of metal embedding and welding ensures a firm connection between the third mounting seat, the third assembly plate and the second shielding layer. The choice of metal material not only provides good conductivity and enhances the electromagnetic shielding effect, but also ensures the long-term stable operation of the enclosure system in harsh environments due to its high strength and corrosion resistance. Welding, as a reliable connection method, can form a continuous and stable electrical connection, further improving the electromagnetic shielding effectiveness of the entire system. In addition, this design also simplifies the assembly process and improves production efficiency, making the film enclosure system of the cryogenic storage tank more convenient and efficient during the manufacturing and installation process.

[0059] In some examples, the first shielding layer and the second shielding layer each include a plurality of spliced ​​sub-bodies, and two adjacent spliced ​​sub-bodies are welded and sealed.

[0060] The above-mentioned splicing design allows the shielding layer to more flexibly adapt to cryogenic storage tanks of different sizes and shapes, improving the versatility and adaptability of the enclosure system. At the same time, the welding and sealing method ensures the close connection between adjacent spliced ​​sub-bodies, effectively preventing the leakage of electromagnetic waves, and further enhancing the electromagnetic shielding effect. In addition, the splicing structure also facilitates the replacement or repair of a single spliced ​​sub-body, reducing maintenance costs and extending the service life of the enclosure system. This design fully considers the actual needs of the cryogenic storage tank enclosure system and provides an efficient and reliable solution for electromagnetic shielding.

[0061] In some examples, in the second shielding layer, at least two spliced ​​sub-bodies are adapted to be connected to the third mounting seat, and after the at least two spliced ​​sub-bodies are sequentially welded to the third mounting seat, the at least two spliced ​​sub-bodies are welded to each other and sealed.

[0062] This design not only enhances the structural strength of the second shielding layer, but also ensures a firm connection between the spliced ​​sub-bodies. Through the adaption connection of the third mounting seat, the spliced ​​sub-bodies can be accurately aligned and fixed, avoiding the reduction of the electromagnetic shielding effect due to improper installation. At the same time, the spliced ​​sub-bodies welded on the third mounting seat in sequence, as well as the welding seals between each other, form a continuous electromagnetic shielding layer, which effectively blocks the propagation path of electromagnetic waves and further improves the electromagnetic shielding performance of the cryogenic tank enclosure system. This refined design and manufacturing process provides a more reliable and efficient solution for the electromagnetic protection of cryogenic tanks.

[0063] In some examples, the first mounting board, the second mounting board, and the third mounting board are all plywood.

[0064] The above material selection not only provides sufficient strength and stability, but also ensures the convenience of the assembly process. Plywood has good bending strength and weather resistance, and can maintain stable performance under different climatic conditions, which is crucial for the long-term operation of the cryogenic tank containment system. In addition, plywood is easy to process and cut, so that the first assembly plate, the second assembly plate and the third assembly plate can be precisely adjusted in size according to actual needs, thereby meeting the diverse installation requirements of the cryogenic tank containment system. The application of this material not only improves assembly efficiency, but also reduces manufacturing costs, providing a cost-effective solution for the film containment system of cryogenic tanks.

[0065] In some examples, the thermal insulation body is made of at least one thermal insulation material selected from the group consisting of polyurethane, foam plastic, mineral wool, glass fiber, and ceramic fiber.

[0066] With their excellent thermal insulation and stability, the above materials can effectively reduce the transfer of heat in low temperature environments, thereby ensuring that the temperature in the cryogenic storage tank is maintained within a set range. Polyurethane has excellent thermal insulation effect and good waterproof performance, which can effectively prevent external moisture and cold air from eroding the interior of the storage tank. Foam plastics, with their light weight, easy processing and low cost, have become one of the commonly used thermal insulation materials in cryogenic storage tank enclosure systems. Mineral wool and glass fiber, with their high temperature stability and good fire resistance, provide additional safety for cryogenic storage tanks. Ceramic fiber, with its high temperature resistance and corrosion resistance, can still maintain a stable thermal insulation effect in extreme environments. By selecting these high-performance thermal insulation materials, the cryogenic storage tank enclosure system of the present application can maintain efficient thermal insulation performance in various harsh environments, thereby ensuring the quality and safety of the materials stored in the storage tank.

[0067] In a second embodiment, the present application further provides a fluid transport device, comprising a cryogenic storage tank and a device body, wherein the cryogenic storage tank comprises the above-mentioned film enclosure system of the cryogenic storage tank. The cryogenic storage tank is arranged in the device body.

[0068] After the fluid transportation equipment has the above-mentioned film enclosure system of the low-temperature storage tank, it can break through the thickness limit of the existing insulation module of the bridge block, and through the setting of the bridge block, the problem of cold leakage in the gap between two adjacent insulation modules can be solved.

[0069] In the process of fluid transportation, cryogenic storage tanks are used to store and transport various liquid or gaseous substances that need to be stored at low temperatures, such as liquefied natural gas, liquid oxygen, liquid nitrogen, etc. The fluid transportation equipment provided by the present application, by adopting the above-mentioned film enclosure system of the cryogenic storage tank, can ensure the efficient thermal insulation performance of the storage tank during transportation, and effectively prevent the degradation of material quality or safety hazards caused by heat transfer.

[0070] The fluid transport equipment can be air transport equipment, land transport equipment, river transport equipment or sea transport equipment, and can be set according to specific needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0085] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0086] A cryogenic storage tank is a container used to store cryogenic liquids (such as liquid natural gas, liquid oxygen, liquid hydrogen, liquid nitrogen, etc.). Its containment system refers to the shell and insulation layer of the tank. The design and material selection of these structures must be able to adapt to and maintain the low temperature environment inside the tank to prevent heat from entering and causing the liquid to heat up, thereby ensuring the stability and safety of the stored substances.

[0087] The cryogenic storage tank of the present application may be a large cryogenic storage tank for ship transportation, and the outer layer may be provided with a protective shell made of cement, stone, brick or other materials and having a hard texture, the protective shell having an assembly cavity, the enclosure system being arranged as a whole in the assembly cavity of the protective shell, and the inner wall of the assembly cavity being the inner wall of the tank described below.

[0088] The cryogenic storage tank of the present application may also be a cryogenic storage tank for vehicle transportation or air transportation, and the material of the protective shell can be set according to needs.

[0089] To solve the above technical problems, please refer to Figure 1-Figure 8 As shown, the first aspect of the present application proposes a film enclosure system for a cryogenic storage tank, which can break through the thickness limitation of the existing insulation module 200 of the bridging block 300, and through the setting of the bridging block 300, the problem of cold leakage in the gap between two adjacent insulation modules 200 can be solved.

[0090] Figure 1 This is a schematic diagram of the structure of some units of the membrane enclosure system of a cryogenic storage tank in an example of the present application. In order to reflect the hierarchy between the modules in the drawings of the present application, some structures of some modules are hidden in the drawings.

[0091] Reference Figure 1 and Figure 2 In some examples, the present application provides a membrane enclosure system for a cryogenic storage tank, the enclosure system being installed on an inner wall 100 of the cryogenic storage tank, and the enclosure system comprising a plurality of thermal insulation modules 200 and a bridging block 300 .

[0092] A plurality of heat insulation modules 200 are installed on the inner wall 100 of the storage tank. The plurality of heat insulation modules 200 are spliced ​​together and cover at least a portion of the inner wall 100 of the storage tank. Assembly grooves 260 are provided at the splicing positions of the heat insulation modules 200 .

[0093] The bridging block 300 is installed in the assembly groove 260 , and the bridging block 300 can connect two adjacent insulation modules 200 together.

[0094] The setting of the bridging block 300 can conveniently increase the thickness of the entire insulation module 200. Breaking through the bridging block 300 can solve the problem of the maximum thickness of the insulation module 200 (such as the insulation module 200 whose insulation material is polyurethane) being 350 mm in the prior art. In addition, by setting the bridging block 300, the problem of cold leakage in the gap between two adjacent insulation modules 200 can be solved. In other words, the film enclosure system of the low-temperature storage tank in the present application can break through the thickness limit of the existing insulation module 200 of the bridging block 300, and by setting the bridging block 300, the problem of cold leakage in the gap between two adjacent insulation modules 200 can be solved.

[0095] Specifically, the containment system is designed and installed on the inner wall of the cryogenic storage tank to provide effective thermal insulation protection.

[0096] The heat insulation module 200 is installed on the inner wall 100 of the storage tank, and covers at least a part of the inner wall 100 of the storage tank by precise splicing. At the splicing position of these heat insulation modules 200, assembly grooves 260 are opened to ensure that the modules can be tightly connected together.

[0097] The bridging blocks 300 are installed in these assembly grooves 260. The function of the bridging blocks 300 is to firmly connect two adjacent insulation modules 200 to form a continuous insulation layer. This design not only improves the overall thickness of the entire insulation system, but also effectively overcomes the thickness limitation of the insulation module 200 in the prior art by increasing the number of bridging blocks 300. For example, when polyurethane is used as the insulation material, the maximum thickness of the traditional insulation module 200 is usually limited to 350 mm. With the setting of the bridging blocks 300, a thicker insulation module 200 can be set, such as an insulation module 200 of 400 mm, 500 mm, 600 mm, etc. The specific thickness can be set as needed and is not limited to the above examples.

[0098] The introduction of the bridge block 300 also solves another technical problem, namely how to effectively reduce or eliminate the gap that may appear between two adjacent insulation modules 200, thereby avoiding the leakage of cold air. Through this design, the insulation performance of the cryogenic storage tank can be significantly improved, ensuring that the low temperature environment inside the storage tank is better maintained.

[0099] Furthermore, the design of the bridge block 300 not only improves the splicing flexibility of the insulation module 200, but also significantly enhances the overall structural stability of the enclosure system. Specifically, the material of the bridge block 300 can be the same or similar to that of the insulation module 200. The bridge block 300 can be used to block the gap between two adjacent insulation modules 200. The bridge block 300 with heat insulation performance can ensure the heat insulation effect of the entire enclosure system.

[0100] In addition, a sealing structure may be provided on the bridge block 300. The sealing structure needs to have a certain elastic deformation margin, which can ensure a certain sealing effect before and after deformation to improve the thermal insulation effect. For example, an elastic sealing strip or a flexible sealant can be used to form an effective seal at the joint of the thermal insulation module 200 to prevent cold leakage and further improve the thermal insulation effect of the enclosure system. The sealing structure may not be provided, and it may be provided according to specific needs.

[0101] The bridging block 300 may also be equipped with a quick connection mechanism, such as a snap, bolt or threaded connection, to facilitate the quick installation and removal of the insulation module 200, thereby simplifying the maintenance and replacement operations of the enclosure system.

[0102] In addition, the design of the bridge block 300 also enhances the structural stability of the containment system, making the connection between the insulation modules 200 more secure and reducing the impact of thermal stress caused by temperature changes on the containment system. In some preferred examples, the bridge block 300 is made of a material compatible with the insulation module 200 to ensure a good thermal conduction isolation effect while maintaining the integrity and strength of the structure. The combined use of the insulation module 200 and the bridge block 300 not only improves the thermal insulation performance of the cryogenic storage tank, but also effectively extends the service life of the storage tank and reduces maintenance costs.

[0103] Furthermore, the shape and size of the heat insulation module 200 can be customized according to the specific conditions of the inner wall 100 of the storage tank to ensure that the heat insulation module 200 can fit closely to the inner wall 100 of the storage tank to reduce heat transfer. In addition, the heat insulation module 200 is made of efficient heat insulation material and has sufficient heat insulation performance, which can effectively reduce the loss of temperature inside the storage tank and improve the heat preservation effect of the storage tank.

[0104] The design of the bridge block 300 also fully considers the stability and reliability of the connection. The two ends of the bridge block 300 are respectively matched with the assembly grooves 260 of the two adjacent insulation modules 200, and through appropriate fixing methods, such as bolt connection, snap connection, etc., the connection between the insulation modules 200 is ensured to be firm and reliable, avoiding loosening or falling off during use.

[0105] In some examples, the bridging block 300 is fixedly connected to the inner wall of the assembly groove 260 , and a deformation margin is provided at the fixed connection position.

[0106] The above-mentioned design allows the bridge block 300 to have a certain degree of adaptability during the installation process, and even when there is a certain manufacturing error or installation error in the size of the assembly groove 260, the bridge block 300 can be ensured to fit tightly with the assembly groove 260. The setting of the deformation margin not only improves the convenience of installation, but also enhances the stability and reliability of the entire containment system. In addition, this design also helps to reduce the structural stress caused by temperature changes or changes in the internal pressure of the storage tank, further extending the service life of the containment system.

[0107] Reference Figures 1 to 3 In some examples, the side of the insulation module 200 close to the inner wall 100 of the storage tank is a fixed side, and the fixed side is fixed to the inner wall 100 of the storage tank by at least one of riveting, bonding, welding, magnetism, and clamping.

[0108] The selection of the above fixing methods is intended to ensure that the connection between the insulation module 200 and the inner wall 100 of the tank is both firm and efficient. Riveting and welding provide a strong mechanical connection that can withstand greater stress or pressure, ensuring that the insulation module 200 will not fall off due to external factors. Adhesive and magnetic methods provide more flexible installation options, especially when the insulation module 200 needs to be installed or replaced quickly, these two methods can significantly improve work efficiency. The snap-on method combines the advantages of firmness and convenience, which not only ensures the stability of the connection, but also facilitates disassembly and maintenance.

[0109] In addition, the design of the fixed side can also maximize the thermal insulation effect. By ensuring the close fit between the thermal insulation module 200 and the inner wall 100 of the storage tank, the heat transfer path is reduced, thereby improving the thermal insulation performance of the entire enclosure system. This design not only helps to maintain the stability of the low-temperature environment inside the storage tank, but also effectively reduces energy consumption and improves energy utilization efficiency.

[0110] Reference Figure 1 and Figure 2 In some examples, a bonding structure 500 is provided between the fixed side and the inner wall 100 of the tank, and an expansion stud 110 is provided on the inner wall 100 of the tank. The expansion stud 110 penetrates part of the insulation module 200 and is locked with the insulation module 200 by a nut.

[0111] The above-mentioned design of composite installation of the two fixing methods not only enhances the connection strength between the heat insulation module 200 and the inner wall 100 of the storage tank, but also provides an additional heat insulation layer, and the bonding structure 500 can also have a certain heat preservation effect, further improving the heat preservation effect. The use of the expansion stud 110 allows the heat insulation module 200 to be fine-tuned during the installation process to ensure that it fits better with the inner wall 100 of the storage tank, reducing heat leakage caused by excessive installation errors.

[0112] At the same time, by locking the nut, the thermal insulation module 200 can be effectively prevented from being displaced due to vibration or temperature changes during long-term use, thereby ensuring the stability and durability of the enclosure system.

[0113] In addition, the combination of the bonding structure 500 and the expansion studs 110 makes the installation of the insulation module 200 more flexible and diverse, and can adapt to the inner walls 100 of the tanks of different shapes and sizes, thereby improving the applicability and practicality of the enclosure system.

[0114] In some examples, the bonding structure 500 includes a plurality of bonding sub-bodies spaced apart from each other. Depending on the shape of the tank inner wall 100 , the thickness of the bonding sub-bodies at different positions are at least partially the same, and / or the thickness of the bonding sub-bodies at different bonding positions are at least partially the same.

[0115] The above-mentioned design enables the bonding structure 500 to better adapt to the complex shape of the inner wall 100 of the storage tank, ensuring the close fit between the thermal insulation module 200 and the inner wall 100 of the storage tank. By adjusting the thickness and distribution of the bonding sub-body, the thermal insulation effect can be further optimized and heat leakage can be reduced. At the same time, the bonding sub-body arranged at intervals can also provide a certain degree of elasticity, so that the thermal insulation module 200 can better adapt to the slight deformation of the inner wall 100 of the storage tank during installation and use, thereby enhancing the stability and durability of the enclosure system. In addition, the design of the bonding structure 500 also simplifies the installation process, improves installation efficiency, and reduces installation costs.

[0116] Reference Figures 1 to 3 In some examples, a reserved hole 270 adapted to the expansion stud 110 is provided on the thermal insulation module 200, and the diameter of the reserved hole 270 is smaller than the diameter of the expansion stud 110 and smaller than the circumscribed circle diameter of the nut.

[0117] The above-mentioned design enables the expansion stud 110 to firmly fix the insulation module 200 on the inner wall 100 of the storage tank after passing through the reserved hole 270 and tightening the nut. The close fit between the reserved hole 270 and the expansion stud 110 effectively prevents the insulation module 200 from loosening and falling off during installation and use, and further enhances the stability and safety of the containment system. At the same time, the provision of the reserved hole 270 also simplifies the installation process, improves the installation efficiency, and makes the installation of the insulation module 200 more convenient and quick. In addition, the adaptation design of the reserved hole 270 and the expansion stud 110 also enables the insulation module 200 to adapt to expansion studs 110 of different specifications and sizes, thereby improving the flexibility and versatility of the containment system.

[0118] Moreover, the arrangement of the above structure can make the enclosure system have more deformation margin, so that the enclosure system has more room for deformation. Inside the cryogenic storage tank, a large number of insulation modules 200 are arranged. Each of these insulation modules 200 is based on the structural design described above, and each insulation module 200 has a certain deformation activity space. This design enables the entire enclosure system to have enough deformation space to cope with fluctuations in external temperature. When the temperature outside the enclosure system changes, these deformation spaces can play an important role, thereby effectively reducing the potential damage to the enclosure system caused by temperature fluctuations.

[0119] In addition, this design also takes into account the problems of material aging and thermal stress accumulation that may occur in the long-term use of cryogenic storage tanks. By providing sufficient deformation margin for the enclosure system, the structural stress concentration caused by these factors can be effectively alleviated, and the service life of the enclosure system can be extended. At the same time, this deformation margin design also enables the enclosure system to better adapt to the operating requirements of cryogenic storage tanks under different working conditions, improving the reliability and safety of the entire storage tank.

[0120] In summary, the membrane enclosure system for the cryogenic storage tank provided in the present application not only improves the installation efficiency and flexibility, but also enhances the stability and safety of the enclosure system, providing a strong guarantee for the long-term stable operation of the cryogenic storage tank.

[0121] Reference Figures 1 to 3 In some examples, the thermal insulation module 200 includes a first mounting plate 210 , a thermal insulation body 220 , and a second mounting plate 230 .

[0122] The first assembly plate 210 is connected to the inner wall 100 of the storage tank, and the fixed side is arranged on the first assembly plate 210 .

[0123] The heat insulating body 220 is connected to the first assembly plate 210 and is located on a side of the first assembly plate 210 facing the inner wall 100 of the storage tank.

[0124] The second assembly plate 230 is connected to the heat insulation body 220 and is located at a side of the heat insulation body 220 away from the first assembly plate 210 .

[0125] The above structural design makes the insulation module 200 have better layering and stability. The firm connection between the first assembly plate 210 and the inner wall 100 of the storage tank ensures that the insulation module 200 can fit tightly on the inner wall 100 of the storage tank, effectively preventing the transfer and leakage of heat. As the core part of the insulation module 200, the insulation body 220 has excellent insulation performance, which can significantly reduce the temperature difference between the inner and outer walls of the storage tank and improve the insulation effect of the storage tank. The second assembly plate 230 plays a role of further protection and fixation, making the insulation module 200 more stable and reliable during installation and use. In addition, this layered design also facilitates the maintenance and replacement of the insulation module 200. When the insulation body 220 is damaged or aged, only the corresponding part needs to be replaced, without the need for overall replacement, which reduces maintenance costs.

[0126] When the insulation module 200 as a whole is damaged or aged, only the corresponding insulation module 200 needs to be replaced without replacing the entire enclosure system, which further reduces maintenance costs.

[0127] Reference Figures 1 to 3In some examples, the insulation body 220 includes a first body 221 and a second body 222, the first side of the first body 221 is connected to the first assembly plate 210, the second side of a portion of the first body 221 is connected to the first side of the second body 222, the second side of a portion of the first body 221 is connected to the second assembly plate 230, and the second side of the second body 222 is connected to the second assembly plate 230.

[0128] An avoidance groove 261 is provided at the edge of the heat insulation body 220 . When two heat insulation modules 200 are spliced ​​together, the two avoidance grooves 261 are spliced ​​together to form an assembly groove 260 .

[0129] The above-mentioned design not only enhances the structural strength of the heat insulation body 220, but also improves the assembly flexibility and sealing between the heat insulation modules 200. The combination of the first body 221 and the second body 222 enables the heat insulation body 220 to better adapt to the inner wall 100 of the storage tank of different shapes and sizes while maintaining excellent heat insulation performance, thereby ensuring the uniformity and consistency of the heat insulation effect.

[0130] Part of the second side of the first body 221 is connected to the first side of the second body 222 , while the other part is connected to the second assembly board 230 . Such a layout optimizes the heat transfer path and reduces the risk of heat leakage.

[0131] The setting of the avoidance groove 261 cleverly solves the assembly problem when splicing the insulation modules 200, so that the two insulation modules 200 can be tightly and firmly spliced ​​together to form a continuous insulation layer, effectively improving the thermal insulation performance of the entire enclosure system.

[0132] In addition, the assembly groove 260 formed by the two avoidance grooves 261 can facilitate the installation of the bridging block 300, allowing the bridging block 300 to sink between the two insulation modules 200 without protruding to occupy more space. The cooperation between the assembly groove 260 and the bridging block 300 can seal the gap between two adjacent insulation modules 200, reduce the cold leakage in the gap, and also facilitate the disassembly and replacement of the insulation module 200, further reducing the maintenance difficulty and cost.

[0133] The first body 221 and the second body 222 are both made of heat-insulating materials. The first body 221 and the second body 222 can be processed successively and then connected by bonding or hot melting. This separate processing method can break through the limitation of the maximum thickness of a single piece and cooperate to process a thicker heat-insulating body 220. The heat-insulating body 220 can also be provided with a third body, a fourth body and other more parts as needed, which can be set according to actual needs.

[0134] Both sides of the insulation module 200 are provided with avoidance grooves 261. When two adjacent insulation modules 200 are spliced, the two avoidance grooves 261 are spliced ​​together to form a larger assembly groove 260, and the assembly groove 260 can be used to install the bridge block 300. The shape of the bridge block 300 is set as required.

[0135] The bridging block 300 also has a three-layer structure, which is respectively a first bridging plate 310 , a heat insulating plate 320 and a second bridging plate 330 . The bridging block 300 as a whole can be embedded in the assembly groove 260 .

[0136] Reference Figures 1 to 3 In some examples, the second assembly plate 230 includes a second assembly main plate 231 and a second assembly sub-plate 232 , the second assembly main plate 231 is disposed on a side of the second body 222 away from the first body 221 , and the second assembly sub-plate 232 is disposed in the avoidance groove 261 .

[0137] The second assembly main board 231 is the main connection component. The second assembly main board 231 is firmly fixed to the outside of the second main body 222, providing reliable support for the insulation module 200. The second assembly sub-board 232 is embedded in the avoidance groove 261, which not only enhances the connection strength between the insulation modules 200, but also ensures the flatness of the joints. The second assembly sub-board 232 can be more stably connected to the bridge block 300 to seal the gap between the two insulation modules 200. This design enables the insulation module 200 to better cooperate with the bridge block 300 during splicing, thereby forming a tighter insulation layer, effectively preventing the transfer of heat, and improving the thermal insulation performance of the entire enclosure system. In addition, the close fit between the second assembly sub-board 232 and the avoidance groove 261 also reduces errors in the assembly process and improves construction accuracy and efficiency.

[0138] Reference Figures 1 to 3 In some examples, at least one first mounting seat 240 is disposed on the second assembly sub-plate 232 , and each first mounting seat 240 is disposed with a first assembly stud 241 , which passes through the bridging block 300 and is anchored to the bridging block 300 .

[0139] The above design enables the second assembly sub-plate 232 and the bridge block 300 to be firmly connected together, further enhancing the structural stability and thermal insulation effect of the entire enclosure system. The first mounting seat 240 is used as a connection point. The reasonable layout of its position and number can ensure that the thermal insulation module 200 is evenly stressed during splicing, avoiding structural damage caused by stress concentration. At the same time, the first assembly stud 241 passes through the bridge block 300 and is anchored to the bridge block 300. This connection method is not only simple and reliable, but also can effectively resist the erosion of the external environment, thereby extending the service life of the enclosure system.

[0140] In addition, the arrangement of the first mounting seat 240 and the first assembly stud 241 also facilitates the disassembly and replacement of the thermal insulation module 200. When the enclosure system needs to be maintained or upgraded, the staff can easily separate the second assembly sub-plate 232 and the bridge block 300 by disassembling the first assembly stud 241, thereby realizing the rapid replacement or adjustment of the thermal insulation module 200. This design not only improves the construction efficiency, but also reduces the maintenance cost, providing a strong guarantee for the long-term stable operation of the cryogenic storage tank.

[0141] The bridging block 300 is provided with an assembly hole 340 adapted to the first assembly stud 241 . After the assembly stud is anchored by a nut or other structure, the assembly hole 340 can be sealed with a heat-insulating material of similar size to reduce cold leakage at the hole position.

[0142] Reference Figures 5 to 8 In some examples, the projection positions of the first assembly stud 241 and the expansion stud 110 on the second assembly sub-plate 232 are staggered.

[0143] Such a configuration can avoid the formation of cold bridges after multiple insulation modules 200 are connected, thereby improving the insulation effect.

[0144] In addition, by staggering the positions of the first assembly studs 241 and the expansion studs 110, the stress caused by assembly can be effectively dispersed, further enhancing the structural stability of the insulation module 200. In the actual application of low-temperature storage tanks, this design can better adapt to various complex environments and working conditions, ensuring the long-term reliable operation of the enclosure system. At the same time, this staggered layout also provides more flexibility for the assembly of the insulation module 200, making the installation process more efficient and convenient.

[0145] In some examples, there is a gap between two adjacent thermal insulation modules 200 , and the spacing between different positions of the gap is always equal, and the gap between two adjacent thermal insulation modules 200 can be filled with thermal insulation material.

[0146] The above-mentioned uniform gap design further optimizes the performance of the enclosure system. By ensuring that the gaps between adjacent insulation modules 200 remain consistent at all locations, the thermal bridge effect can be effectively avoided, heat transfer can be reduced, and the insulation effect of the entire cryogenic storage tank can be improved. In addition, uniform gaps also help maintain the stability of the temperature field inside the enclosure system and reduce temperature fluctuations, which is particularly important for storing temperature-sensitive media. At the same time, this design also simplifies the installation process, allowing staff to complete the splicing of the insulation modules 200 more quickly and accurately, improving construction efficiency and quality.

[0147] Such a gap design not only helps to improve the overall insulation performance, but also effectively prevents mutual squeezing or deformation between modules due to thermal expansion. The filling of thermal insulation material further enhances the thermal insulation effect and reduces the possibility of heat transfer. At the same time, the equally spaced gap layout makes the filling of thermal insulation material more uniform, avoiding local overheating or overcooling, thereby ensuring the stability and reliability of the entire enclosure system. In the application of fluid transportation equipment, this design can significantly improve the thermal insulation performance of the equipment, reduce energy consumption, and extend service life.

[0148] The above-mentioned gap can be set within the range of 20mm±5mm on the same side. Such a size design not only meets the precision requirements during the assembly of the insulation module 200, but also ensures the stability and reliability of the containment system under various working conditions. The gap range of 20mm±5mm not only takes into account the error tolerance during the installation process, but also ensures the close fit between the insulation modules 200, avoiding the problem of heat leakage caused by excessive gaps. At the same time, this design also provides convenience for subsequent maintenance and overhaul. The staff can easily inspect and replace the insulation module 200 without destroying the overall structure of the containment system. In summary, the design of the above-mentioned gap size is an important innovation in the cryogenic storage tank containment system, which significantly improves the thermal insulation performance and installation efficiency of the system.

[0149] Reference Figures 9 to 12 In some examples, the enclosure system further includes a heat insulation corner module 600, which includes a first bending portion 610 and a second bending portion 620. The first bending portion 610 and the second bending portion 620 are arranged at an angle. The heat insulation corner module 600 is arranged adjacent to the heat insulation module 200, and the connection method is the same as the connection method between two adjacent heat insulation modules 200. Figures 9 to 12 Two types of thermal insulation corner modules 600 are shown in the figure, and the thermal insulation corner modules 600 in the present application are not limited to the two types shown in the figure.

[0150] The design of the above-mentioned insulating corner module 600 enhances the thermal insulation performance of the enclosure system in the corner area. The angle setting of the first bend 610 and the second bend 620 can be adjusted according to specific needs to adapt to corner areas of different angles, thereby ensuring the integrity and continuity of the enclosure system. By connecting the insulating corner module 600 to the insulating module 200 in the same manner, not only the installation process is simplified, but also the stability and reliability of the entire enclosure system structure are guaranteed. In addition, the use of the insulating corner module 600 also effectively reduces the heat loss caused by insufficient insulation in the corner area, further improving the insulation effect and energy efficiency of the cryogenic storage tank.

[0151] The design of the insulation corner module 600 allows it to be conveniently connected to the insulation module 200 through the bridge block 300, which provides flexible installation options. In addition, the connection between two adjacent insulation corner modules 600 can also be achieved by using the bridge block 300 to complete this process. The choice of this connection method depends entirely on the needs and design considerations in the actual application.

[0152] In the design of the heat insulation corner module 600, the angle between the first bending portion 610 and the second bending portion 620 can be adjusted according to specific application requirements. The adjustment range of this angle is very wide, and can be any angle between 0 degrees and 180 degrees. In order to meet different design requirements, each part of the first bending portion 610 and the second bending portion 620 can be designed to be arc-shaped. Such a design is not only beautiful, but also can provide a certain bending structure, thereby meeting specific engineering requirements.

[0153] Reference Figures 4 to 8 In some examples, the enclosure system further includes a shielding module 400 , which is connected to the thermal insulation module 200 .

[0154] At least one second mounting seat 250 is disposed on the second mounting plate 230 . Each second mounting seat 250 is disposed with a second mounting stud 251 . The second mounting stud 251 is connected to the shielding module 400 .

[0155] The design of the above-mentioned shielding module 400 enhances the electromagnetic shielding performance of the containment system and effectively prevents the influence of external electromagnetic interference on the interior of the cryogenic storage tank. The connection method between the shielding module 400 and the thermal insulation module 200 ensures the stability of the structure and is also convenient for installation and maintenance. The design of the second mounting seat 250 and the second assembly stud 251 on the second assembly plate 230 provides a reliable mounting point for the shielding module 400 and ensures the close connection between the shielding module 400 and other parts of the containment system. This design not only improves the overall performance of the containment system, but also provides a strong guarantee for the safe operation of the cryogenic storage tank.

[0156] It should be known that the shielding layer in the film enclosure system of the cryogenic storage tank mainly plays the role of electromagnetic shielding. During the operation of the cryogenic storage tank, various electromagnetic wave interferences may be generated, which will not only affect the normal operation of the equipment inside the tank, but also may have adverse effects on the surrounding environment. The shielding layer is set to effectively block the propagation of these electromagnetic waves, ensuring the stability of the internal environment of the tank and the safety of the external environment.

[0157] Specifically, the shielding layer can absorb, reflect or guide electromagnetic waves, making them unable to penetrate the enclosure system, thereby achieving a shielding effect. This shielding effect not only improves the electromagnetic compatibility of the storage tank, but also protects the cryogenic medium stored in the tank from interference from external electromagnetic waves, ensuring the quality and safety of the medium.

[0158] Therefore, the shielding layer in the membrane enclosure system of the cryogenic storage tank is an important component to ensure the normal operation of the tank and the safety of the surrounding environment.

[0159] In some examples, the shielding module 400 includes a first shielding layer 410 , a second shielding layer 420 , and a third assembly board 430 . The first shielding layer 410 is spaced apart from the second shielding layer 420 , and the third assembly board 430 is located between the first shielding layer 410 and the second shielding layer 420 .

[0160] The design of the shielding module 400 includes three main parts, namely, a first shielding layer 410, a second shielding layer 420 and a third assembly plate 430. The first shielding layer 410 is arranged to maintain a certain spacing distance from the second shielding layer 420, and the third assembly plate 430 is cleverly arranged between the first shielding layer 410 and the second shielding layer 420. Such a structural design is intended to achieve a more effective shielding effect.

[0161] The spacing between the first shielding layer 410 and the second shielding layer 420 helps to reduce the capacitive coupling effect between the shielding layers, thereby reducing the penetration of electromagnetic waves. The third assembly board 430 serves as a connection and support structure, which can enhance the mechanical strength of the shielding module 400.

[0162] The first assembly plate 210 , the second assembly plate 230 and the third assembly plate 430 can all be made of plywood, or other materials as required.

[0163] Furthermore, the electromagnetic shielding performance is further optimized through the selection of materials and structural design of the third assembly plate 430. For example, the third assembly plate 430 can be made of a highly conductive material to provide an additional electromagnetic shielding layer, while ensuring that the electrical connection between the first shielding layer 410 and the second shielding layer 420 is stable and reliable. This multi-layer shielding structure design enables the enclosure system to exhibit better shielding performance when facing a complex electromagnetic environment, providing a more solid guarantee for the safe operation of the cryogenic storage tank.

[0164] In some examples, the second assembly stud 251 passes through the first shielding layer 410 and is connected to the third assembly plate 430 ; and / or, the first shielding layer 410 is provided with a third assembly stud 411 , and the third assembly stud 411 is connected to the third assembly plate 430 .

[0165] The above design not only further enhances the structural stability of the enclosure system, but also optimizes the path of electromagnetic shielding. Specifically, the second assembly stud 251 penetrates the first shielding layer 410 and is connected to the third assembly plate 430, forming a tighter assembly structure and reducing the possibility of electromagnetic leakage.

[0166] At the same time, the connection between the third assembly stud 411 additionally provided on the first shielding layer 410 and the third assembly plate 430 further enhances the firmness of the overall structure, so that the enclosure system can function more stably when facing external electromagnetic interference. This design not only improves the electromagnetic shielding effectiveness, but also provides a strong guarantee for the safe operation of the cryogenic storage tank.

[0167] In some examples, a third mounting seat 431 is disposed on a side of the third assembly plate 430 facing away from the first shielding layer 410 , and the second shielding layer 420 is fixedly connected to the third mounting seat 431 .

[0168] The above design details further strengthen the overall structure of the enclosure system. The third mounting seat 431 provided on the third assembly plate 430 provides a stable support point for the fixed connection of the second shielding layer 420. Through precise assembly technology, the second shielding layer 420 is closely connected to the third mounting seat 431 to form a seamless electromagnetic shielding network. Such a design not only enhances the structural strength of the enclosure system, but also optimizes the electromagnetic shielding effect, so that the entire system can show higher stability and reliability when facing a complex electromagnetic environment. In addition, this design also facilitates subsequent maintenance and overhaul work, reducing the operation and maintenance costs of the system.

[0169] In some examples, the third mounting seat 431 is a metal piece and is embedded in the third assembly board 430 , and the second shielding layer 420 is welded to the third mounting seat 431 .

[0170] The above-mentioned combination of metal embedding and welding ensures a firm connection between the third mounting seat 431 and the third assembly plate 430 and the second shielding layer 420. The choice of metal material not only provides good conductivity and enhances the electromagnetic shielding effect, but also ensures the long-term stable operation of the enclosure system in harsh environments due to its high strength and corrosion resistance. Welding, as a reliable connection method, can form a continuous and stable electrical connection, further improving the electromagnetic shielding effectiveness of the entire system. In addition, this design also simplifies the assembly process and improves production efficiency, making the film enclosure system of the cryogenic storage tank more convenient and efficient during the manufacturing and installation process.

[0171] In some examples, the first shielding layer 410 and the second shielding layer 420 each include a plurality of spliced ​​sub-bodies, and two adjacent spliced ​​sub-bodies are welded and sealed, wherein the spliced ​​sub-bodies constituting the first shielding layer 410 are first spliced ​​sub-bodies, and the spliced ​​sub-bodies constituting the second shielding layer 420 are second spliced ​​sub-bodies; part of the first spliced ​​sub-bodies are welded to the second mounting seat 250, and part of the second spliced ​​sub-bodies are welded to the third mounting seat 431.

[0172] The above-mentioned splicing design allows the shielding layer to more flexibly adapt to cryogenic storage tanks of different sizes and shapes, improving the versatility and adaptability of the enclosure system. At the same time, the welding and sealing method ensures the close connection between adjacent spliced ​​sub-bodies, effectively preventing the leakage of electromagnetic waves, and further enhancing the electromagnetic shielding effect. In addition, the splicing structure also facilitates the replacement or repair of a single spliced ​​sub-body, reducing maintenance costs and extending the service life of the enclosure system. This design fully considers the actual needs of the cryogenic storage tank enclosure system and provides an efficient and reliable solution for electromagnetic shielding.

[0173] Part of the first spliced ​​sub-body is welded to the second mounting seat 250, and part of the second spliced ​​sub-body is welded to the third mounting seat 431. This connection method not only improves the connection strength between the shielding layer and the mounting seat, but also ensures the stability and reliability of the shielding layer in the enclosure system. This design enables the film enclosure system of the cryogenic storage tank to always maintain excellent electromagnetic shielding performance when facing a complex and changeable electromagnetic environment, providing a strong guarantee for the normal operation of the fluid transportation equipment.

[0174] In some examples, the portion of the first splicing sub-body connected to the second mounting seat 250 is provided with a first cut angle, at least two first splicing sub-bodies are connected to the second mounting seat 250 and are relatively sealed, at least two first cut angles are spliced ​​to form a through hole, and the second assembly stud 251 is welded to the second mounting seat and passes through the through hole.

[0175] This design not only optimizes the connection structure between the splicing sub-body and the mounting seat, but also enhances the overall sealing performance. The setting of the first cutting angle enables the adjacent first splicing sub-bodies to fit more closely when connected, reducing the risk of electromagnetic wave leakage caused by the splicing gap. At the same time, at least two first splicing sub-bodies are relatively sealed and connected to the second mounting seat 250, further improving the continuity and integrity of the shielding layer. The formation of the through hole provides accurate positioning for the second assembly stud 251, ensuring that the stud can be firmly welded to the second mounting seat and the splicing sub-body is tightly fixed together through the through hole. This sophisticated design not only improves the structural strength of the enclosure system, but also effectively guarantees the stability and durability of the electromagnetic shielding effect.

[0176] In some examples, during the assembly process of the first shielding layer 410, at least two first spliced ​​sub-bodies are overlapped to the second mounting seat in sequence and spot welded, and then two adjacent spliced ​​sub-bodies are welded and sealed, the part of the first spliced ​​sub-body connected to the second mounting seat 250 is welded and sealed, and the second assembly stud 251 is welded to the second mounting seat through the through hole.

[0177] This assembly step ensures the stability and reliability of the first shielding layer 410 during the construction process. First, at least two first splicing sub-bodies are accurately placed and overlapped on the second mounting seat, and are initially fixed by spot welding, which provides a basis for subsequent more refined welding. Next, the two adjacent splicing sub-bodies are tightly connected by welding, and at the same time, the sealing is ensured. This step is crucial to prevent fluid leakage and maintain the stability of the internal environment. Subsequently, the connection between the first splicing sub-body and the second mounting seat 250 is also welded and sealed, which not only enhances the integrity of the structure, but also further enhances the shielding effect. Finally, through the through hole, the second assembly stud 251 is accurately welded to the second mounting seat. This step not only consolidates the fixation of the splicing sub-body, but also ensures the structural strength of the entire enclosure system. This meticulous and orderly assembly process enables the film enclosure system of the cryogenic storage tank to maintain its performance in extreme environments, thereby ensuring the stable operation of the fluid transport equipment.

[0178] In some examples, in the second shielding layer 420 , at least two spliced ​​sub-bodies are adapted to be connected to the third mounting seat 431 , and after the at least two spliced ​​sub-bodies are sequentially welded to the third mounting seat 431 , the at least two spliced ​​sub-bodies are welded to each other and sealed.

[0179] This design not only enhances the structural strength of the second shielding layer 420, but also ensures a firm connection between the spliced ​​sub-bodies. Through the adaption connection of the third mounting seat 431, the spliced ​​sub-bodies can be accurately aligned and fixed, avoiding the reduction of the electromagnetic shielding effect due to improper installation. At the same time, the spliced ​​sub-bodies welded to the third mounting seat 431 in sequence, as well as the welding seals between each other, form a continuous electromagnetic shielding layer, which effectively blocks the propagation path of electromagnetic waves and further improves the electromagnetic shielding performance of the cryogenic tank enclosure system. This refined design and manufacturing process provides a more reliable and efficient solution for the electromagnetic protection of cryogenic tanks.

[0180] In some examples, the first mounting board 210 , the second mounting board 230 , and the third mounting board 430 may all be plywood.

[0181] The above material selection not only provides sufficient strength and stability, but also ensures the convenience of the assembly process. Plywood has good bending strength and weather resistance, and can maintain stable performance under different climatic conditions, which is crucial for the long-term operation of the cryogenic tank containment system. In addition, plywood is easy to process and cut, so that the first assembly plate 210, the second assembly plate 230 and the third assembly plate 430 can be precisely adjusted in size according to actual needs, thereby meeting the diverse installation requirements of the cryogenic tank containment system. The application of this material not only improves assembly efficiency, but also reduces manufacturing costs, providing a cost-effective solution for the film containment system of cryogenic storage tanks.

[0182] The first assembly plate 210 , the second assembly plate 230 and the third assembly plate 430 may also be replaced with plate structures made of other materials as needed.

[0183] In some examples, the heat insulating body 220 is made of at least one heat insulating material selected from the group consisting of polyurethane, foam plastic, mineral wool, glass fiber, and ceramic fiber.

[0184] With their excellent thermal insulation and stability, the above materials can effectively reduce the transfer of heat in low temperature environments, thereby ensuring that the temperature in the cryogenic storage tank is maintained within a set range. Polyurethane has excellent thermal insulation effect and good waterproof performance, which can effectively prevent external moisture and cold air from eroding the interior of the storage tank. Foam plastics, with their light weight, easy processing and low cost, have become one of the commonly used thermal insulation materials in cryogenic storage tank enclosure systems. Mineral wool and glass fiber, with their high temperature stability and good fire resistance, provide additional safety for cryogenic storage tanks. Ceramic fiber, with its high temperature resistance and corrosion resistance, can still maintain a stable thermal insulation effect in extreme environments. By selecting these high-performance thermal insulation materials, the cryogenic storage tank enclosure system of the present application can maintain efficient thermal insulation performance in various harsh environments, thereby ensuring the quality and safety of the materials stored in the storage tank.

[0188] In addition, the design of this fluid transportation equipment is flexible and diverse. Different modes of transportation such as air, land, river or sea transportation can be selected according to actual needs. It is widely used in various industrial, medical, scientific research and other fields. In air transportation equipment, cryogenic storage tanks can be fixed in the cargo hold of the aircraft, and special fixing devices and shock absorption systems are used to ensure stability and safety during flight. In land transportation equipment, cryogenic storage tanks can be installed on trucks, trains and other means of transportation, equipped with professional cooling systems and monitoring systems to monitor the temperature and pressure in the tanks in real time to ensure the safety and reliability of the transportation process. In river and sea transportation equipment, cryogenic storage tanks are usually fixed in the cargo hold of the ship, and professional fixing and insulation measures are used to effectively resist the impact of wind and waves and temperature changes on the substances in the tanks.

[0189] The design of this fluid transportation equipment fully considers the safety and stability of cryogenic storage tanks in various transportation environments. The efficient thermal insulation performance of the enclosure system ensures that the quality of the cryogenic materials in the tank will not be affected by external temperature changes during long-distance transportation. At the same time, the close integration of the equipment body and the cryogenic storage tank improves the overall transportation efficiency and safety.

[0190] Whether it is the low temperature environment that needs to be strictly controlled in air transportation equipment, or the complex climatic conditions that may be faced in land, river, and sea transportation, the fluid transportation equipment of this application can provide reliable protection. This fluid transportation equipment is not only suitable for the transportation of temperature-sensitive substances in specific industries such as medicine and chemicals, but is also widely used in food, cold chain logistics and other fields to meet the needs of different industries for low-temperature transportation.
