Description

Technical Field

[0001] The present application relates to the field of fluid transportation technology, and in particular to a containment 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 the existing bridge block is unstable. Summary of the invention

[0005] The present application provides a containment system and fluid transport equipment for a cryogenic storage tank, which can make the connection between the bridging block and the insulation module more stable and reliable, and through the corresponding structural design, break through the thickness limitation faced by the traditional bridging block when connecting the existing insulation module.

[0006] In a first aspect, the present application provides a containment system for a cryogenic storage tank, wherein the containment system is installed on an inner wall of the cryogenic storage tank, and the containment 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, and the plurality of heat insulation modules are spliced ​​together to cover at least a portion of the inner wall of the storage tank. Assembly grooves are provided at the splicing positions of the heat insulation modules.

[0008] The bridging block is installed in the assembly groove, and the bridging block can connect two adjacent insulation modules together. The bridging block is fixedly connected to the insulation module via a fastener.

[0009] The bridging block is provided with an assembly hole matched with the fastener. The bridging block comprises a first bridging plate, a heat insulating plate and a second bridging plate. The heat insulating plate is located between the first bridging plate and the second bridging plate.

[0010] The area where the assembly hole is located passes through the first bridging plate, the heat insulation plate and the second bridging plate at the same time, and the fastener is installed on the heat insulation module and passes through the assembly hole from the position of the first bridging plate.

[0011] The setting of the bridging block can conveniently increase the thickness of the entire insulation module. After adding the bridging block, 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) can be solved. In addition, the setting of the bridging block can solve the problem of cold leakage in the gap between two adjacent insulation modules. In other words, the 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 the setting of the bridging block can solve the problem of cold leakage in the gap between two adjacent insulation modules. Specifically, the enclosure system can be designed and installed on the inner wall of the low-temperature storage tank to provide effective insulation protection.

[0012] The above insulation modules will be spliced ​​together and cover at least a part of the inner wall of the tank. In order to ensure the tight splicing between the modules, an assembly groove is designed at the splicing position of each insulation module to assemble a bridge block. The function of the bridge block is to connect two adjacent insulation modules to enhance the stability of the overall structure. These bridge blocks are fixedly connected to the insulation modules by fasteners to ensure the firmness of the connection.

[0013] In order to achieve a stable connection between the bridge block and the insulation module, an assembly hole adapted to the fastener is specially provided on the bridge block. The assembly hole passes through the first bridge plate, the insulation plate and the second bridge plate, so that the fastener can be passed through the insulation module and installed in the assembly hole. The first bridge plate and the second bridge plate can make the fixed connection of the bridge block more stable and reliable.

[0014] The above structure not only makes the connection between the bridging block and the insulation module more stable and reliable, but also breaks through the thickness limitation faced by the traditional bridging block when connecting the existing insulation module through the corresponding structural design.

[0015] In some examples, the assembly hole includes a first through portion, a second through portion, and a third through portion, the first through portion penetrating the first bridging plate, the second through portion penetrating the thermal insulation board, and the third through portion penetrating the second bridging plate.

[0016] The cross-sectional size of the first penetration portion is smaller than the cross-sectional sizes of the second penetration portion and the third penetration portion.

[0017] Such a design enables the assembly holes to form a stepped structure in the bridge block, which is beneficial to enhancing the connection strength and stability of the bridge block. The smaller cross-sectional size of the first penetration portion facilitates the assembly of fasteners, such as bolts or screws, and the first bridge plate is fixedly connected to the adjacent insulation module or structural member through the first penetration portion. The larger cross-sectional sizes of the second and third penetration portions provide sufficient space to facilitate the connection of fasteners, so that the insulation board can be firmly installed between the two bridge plates to ensure that the insulation effect is not destroyed. In addition, the design of this stepped structure also helps to disperse the stress generated during the assembly process, further improving the durability and reliability of the bridge block.

[0018] In some examples, the assembly hole is a circular hole, and the aperture of the first through-hole portion is smaller than the apertures of the second through-hole portion and the third through-hole portion.

[0019] Alternatively, the assembly hole is a square hole or a diamond hole, and the cross-sectional side length of the first through-portion is smaller than the cross-sectional side lengths of the second through-portion and the third through-portion.

[0020] This design not only meets the assembly requirements, but also provides a variety of options for the bridge block. When the assembly hole is a round hole, its smooth edge helps to reduce friction during assembly and reduce the risk of fastener wear. At the same time, the design of different hole diameters allows fasteners to choose the appropriate size according to needs, ensuring the tightness and stability of the connection.

[0021] When the assembly hole is a square hole or a diamond hole, this non-circular cross-sectional shape can more effectively resist shear force and improve the shear strength of the bridge block. In addition, the design of the square hole or diamond hole is also convenient for guiding the installation of fasteners in a specific direction, making the assembly process more accurate and efficient.

[0022] Whether it is a round hole, a square hole or a diamond hole, the design of the assembly hole fully considers the connection requirements and use environment of the bridge block, ensuring its reliability and durability in fluid transportation equipment.

[0023] In some examples, the fastener passes through the first through-portion and is partially located in the second through-portion, and the portion of the fastener extending into the second through-portion is locked by a nut, and the nut is tightened and abuts against the first bridging plate.

[0024] This structure not only ensures that the fastener is firmly installed in the bridge block, but also provides a convenient locking method. When the fastener passes through the first penetration portion and enters the second penetration portion, its length is sufficient to penetrate the two components and achieve an effective connection. Subsequently, the fastener is locked in the second penetration portion by a nut, which not only enhances the stability of the connection, but also effectively prevents the fastener from loosening due to vibration or external force.

[0025] In addition, the design of the nut being locked and abutted against the first bridge plate further enhances the rigidity and durability of the connection. This abutment method not only disperses the force of the fastener and reduces the load on a single part, but also improves the overall performance of the entire bridge structure.

[0026] Through the cooperation of the fastener, the first penetration part, the second penetration part and the nut, a reliable connection between the bridging blocks is achieved, providing a strong guarantee for the stable operation of the fluid transportation equipment.

[0027] In some examples, a cross-sectional dimension of the fastener is smaller than a cross-sectional dimension of the first through-portion, and a clearance space is provided between the fastener and the first through-portion.

[0028] The cross-sectional dimension of the nut is greater than the cross-sectional dimension of the first penetration portion, and when the fastener and the first bridge plate slide relative to each other, the nut always maintains a locked state.

[0029] This structure has multiple advantages. First, the cross-sectional size of the fastener is smaller than that of the first penetration portion, which provides sufficient space for the fastener to move, facilitating flexible operation during installation and adjustment. The presence of the clearance space not only simplifies the installation steps, but also allows the fastener to be fine-tuned when necessary to ensure its precise positioning.

[0030] Secondly, the cross-sectional size of the nut is larger than that of the first penetration portion, which effectively prevents the nut from accidentally falling off during normal use. Even if relative slippage occurs between the fastener and the first bridge plate, the nut can still remain locked due to its larger cross-sectional size, thereby maintaining the stability and safety of the connection.

[0031] The above-mentioned size design not only improves the overall performance of the bridging structure, but also provides a solid guarantee for the long-term stable operation of the fluid transportation equipment.

[0032] In some examples, at least one washer is sleeved on the fastener, and the washer is located between the nut and the first bridge plate.

[0033] The design of this gasket further enhances the stability and sealing of the bridge structure. The presence of the gasket can effectively fill the tiny gap between the nut and the first bridge plate, preventing the fluid from leaking through these gaps, thereby ensuring the sealing performance of the fluid transport equipment. In addition, the gasket can also play a role in buffering and shock absorption, reducing stress concentration caused by vibration or impact, and extending the service life of fasteners and bridge plates. In specific application scenarios, gaskets of different materials and thicknesses can be selected to meet different sealing and buffering requirements, thereby achieving customized optimization of the performance of the bridge structure.

[0034] In some examples, after the nut locks the fastener, the second through-portion and the third through-portion are filled with a heat-insulating filler having a matching shape.

[0035] This insulating filler is designed to further reduce heat transfer and improve the thermal insulation performance of the cryogenic tank. The insulating filler is usually made of materials with low thermal conductivity, such as polyurethane foam, rock wool or aerogel, which can effectively block the conduction path of heat through the second penetration and the third penetration. By precisely matching the shape of the insulating filler with the inner cavity of the penetration, it can be ensured that the filling is tight and seamless, and heat is prevented from penetrating through tiny gaps. In addition, the insulating filler can also enhance the structural strength between the fastener and the bridge plate, making it more stable and reliable when subjected to thermal and mechanical stresses in low-temperature environments. This design not only improves the insulation efficiency of the cryogenic tank, but also provides strong support for the stable operation of fluid transportation equipment under extreme temperature conditions.

[0036] In some examples, the insulation module includes a first mounting plate, an insulation body, and a second mounting plate.

[0037] The first assembly plate is connected to the inner wall of the storage tank. The heat insulation body is connected to the first assembly plate and is located on a side of the first assembly plate away from the inner wall of the storage tank. The second assembly plate is connected to the heat insulation body and is located on a side of the heat insulation body away from the first assembly plate, and the fastener is installed on the second assembly plate.

[0038] After the fasteners are installed on the second assembly plate, the stability and firmness of the entire thermal insulation module can be ensured.

[0039] 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.

[0040] In some examples, the insulation body includes a first body and a second body, wherein a first side of the first body is connected to the first assembly plate, a portion of the second side of the first body is connected to the first side of the second body, a portion of the second side of the first body is connected to the second assembly plate, and a second side of the second body is connected to the second assembly plate.

[0041] 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 the assembly groove.

[0042] The second assembly plate includes a second assembly main plate and a second assembly sub-plate, the second assembly main plate is arranged on a side of the second main body away from the first main body, the second assembly sub-plate is arranged in the avoidance groove, and the fastener is installed on the second assembly sub-plate.

[0043] This structure not only enhances the structural strength of the insulation module, but also improves its assembly flexibility. When multiple insulation modules need to be connected, the design of the avoidance groove makes it easier to assemble adjacent insulation modules. Just align and splice two avoidance grooves to form a complete assembly groove, which is convenient for the installation of fasteners.

[0044] The combination of the second assembly main board and the second assembly sub-board further improves the stability of the insulation module. The second assembly main board serves as the main supporting structure, ensuring the stability of the insulation module during installation and use. The second assembly sub-board is cleverly set in the avoidance groove, which not only does not affect the overall appearance of the insulation module, but also provides an installation position for fasteners, making the connection between insulation modules tighter and more reliable.

[0045] In some examples, at least one mounting seat is disposed on the second assembly sub-plate, and the fastener is disposed on each mounting seat. The fastener passes through the bridging block and is anchored to the bridging block.

[0046] This structure not only enhances the connection strength between the insulation modules, but also ensures the stability and accuracy of the fasteners during the installation process. The setting of the mounting seat provides a stable support point for the fasteners, avoiding the problem of insulation module connection failure caused by loose fasteners. At the same time, the fasteners pass through the bridge block and are anchored to the bridge block. This connection method further improves the overall stability and reliability of the insulation module. As a key component connecting two insulation modules, the strength and stability of the bridge block are crucial. Through this structure, a strong connection is formed between the bridge block and the fastener, which effectively transmits the force and torque between the insulation modules, thereby ensuring the stability and safety of the entire insulation system.

[0047] In some examples, a receiving groove matched with the mounting seat is formed on the second assembly sub-plate, and the mounting seat is embedded in the receiving groove.

[0048] It can be ensured that the mounting seat will not protrude too much from the surface of the second assembly secondary plate after installation, and the mounting seat can be limited by the accommodating groove to improve the installation stability.

[0049] This structure not only optimizes the appearance of the insulation module and reduces the risk of collision or damage caused by the protrusion of the mounting seat, but also ensures the precise alignment of the mounting seat during installation through the limiting function of the receiving groove, avoiding the problem of unstable connection caused by position deviation. In addition, the close fit between the receiving groove and the mounting seat effectively prevents the external environment from corroding the mounting seat, extending the service life of the fasteners and the entire insulation module. This refined design reflects the high attention and control of the connection details of the insulation module, further improving the overall performance and reliability of the insulation system.

[0050] In some examples, the mounting base is fixedly connected to the second assembly sub-board, and the fixing method includes at least one of bonding, clamping, magnetic attraction, and connection with a fixing piece.

[0051] This fixing method is flexible and diverse in design, and can meet the installation requirements in different application scenarios. The bonding method is suitable for scenarios that require strong connection force and good sealing. The mounting base is firmly attached to the second assembly sub-board through a special adhesive to ensure that the connection is stable and not easy to fall off. The snap-on method is convenient for quick installation and disassembly. Through the cleverly designed snap-on structure, the convenient connection between the mounting base and the second assembly sub-board is realized, which improves the assembly efficiency. The magnetic suction method is suitable for scenarios where the position of the mounting base needs to be frequently replaced or adjusted. The principle of magnetic adsorption is used to achieve flexible positioning of the mounting base. The fixing part connection method provides a more reliable mechanical connection. The mounting base is firmly fixed to the second assembly sub-board through fasteners such as bolts and nuts. It is suitable for environments with large loads or large vibrations. The flexible use of these fixing methods not only improves the stability and reliability of the mounting base, but also provides users with more diverse installation options, enhancing the adaptability and flexibility of cryogenic storage tank containment systems and fluid transportation equipment.

[0052] In some examples, fixing holes are respectively formed at four corners of the mounting seat, and the mounting seat is connected to the second assembly via a fixing member, and the fixing member fixes the mounting seat to the second assembly sub-board through the fixing holes.

[0053] This structure not only enhances the stability of the connection, but also facilitates precise positioning during installation. The setting of the fixing holes enables the fixings to be evenly distributed, thereby dispersing the force at the connection point and improving the overall load-bearing capacity and safety. At the same time, fixing through the fixing holes can also effectively prevent the mounting base from deformation or loosening due to uneven force during long-term use. In addition, this fixing method is also convenient for subsequent maintenance and inspection work, because the fixings are usually easy to disassemble and reinstall without destroying the original connection structure. Therefore, this design of connecting the mounting base and the second assembly sub-plate using fixing holes and fixings not only improves the reliability and durability of the product, but also brings great convenience to the user's operation and maintenance.

[0054] In some examples, the fixing member includes at least one of a screw, a rivet, and an expansion screw for fixing connection.

[0055] The choice of these fixings depends on the specific application scenario and requirements. For example, screws are often used to connect components that require frequent maintenance or inspection because they are easy to remove and reinstall. Rivets are more suitable for situations that require higher strength and permanent connections because they are difficult to remove once installed, providing a more stable connection. Expansion screws are often used in scenarios where they need to be fixed on softer or fragile materials. They generate friction by expanding to achieve a firm fixation effect. Choosing appropriate fixings not only ensures the safety and stability of the connection, but also improves the overall assembly efficiency and maintainability. Therefore, during the design and manufacturing process, it is crucial to select appropriate fixings according to actual needs.

[0056] In a second aspect, 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 enclosure system of the cryogenic storage tank as described above. The cryogenic storage tank is arranged in the device body.

[0057] 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.

[0058] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] To solve the above technical problems, please refer to Figure 1-Figure 10As shown, the first aspect of the present application proposes a containment system for a low-temperature storage tank, which can make the connection between the bridging block 300 and the insulation module 200 more stable and reliable, and through the corresponding structural design, it breaks through the thickness limitation faced by the traditional bridging block 300 when connecting the existing insulation module 200.

[0076] Figure 1 This is a schematic diagram of the structure of some units of the 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.

[0077] Reference Figure 1 and Figure 2 In some examples, the present application provides a containment system for a cryogenic storage tank, the containment system being installed on an inner wall 100 of the cryogenic storage tank, and the containment system comprising a plurality of thermal insulation modules 200 and a bridging block 300 .

[0078] 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 .

[0079] The bridging block 300 is installed in the assembly groove 260 . The bridging block 300 can connect two adjacent insulation modules 200 together. The bridging block 300 is fixedly connected to the insulation module 200 via a fastener 241 .

[0080] The bridging block 300 is provided with an assembly hole 340 adapted to the fastener 241 . The bridging block 300 includes a first bridging plate 310 , a heat insulating plate 320 and a second bridging plate 330 . The heat insulating plate 320 is located between the first bridging plate 310 and the second bridging plate 330 .

[0081] The area where the assembly hole 340 is located passes through the first bridging plate 310 , the insulation plate 320 and the second bridging plate 330 . The fastener 241 is installed on the insulation module 200 and passes through the assembly hole 340 from the position of the first bridging plate 310 .

[0082] The provision of the bridging block 300 can conveniently increase the thickness of the entire insulation module 200. After adding the bridging block 300, 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 can be solved. Moreover, by providing 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 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 providing the bridging block 300, the problem of cold leakage in the gap between two adjacent insulation modules 200 can be solved. Specifically, the enclosure system can be designed and installed on the inner wall of the low-temperature storage tank to provide effective insulation protection.

[0083] The above-mentioned insulation modules 200 will be spliced ​​with each other and cover at least a part of the inner wall 100 of the storage tank. In order to ensure the tight splicing between the modules, an assembly groove 260 is designed at the splicing position of each insulation module 200 to assemble the bridge block 300. The function of the bridge block 300 is to connect two adjacent insulation modules 200 to enhance the stability of the overall structure. These bridge blocks 300 are fixedly connected to the insulation modules 200 by fasteners 241 to ensure the firmness of the connection.

[0084] In order to achieve a stable connection between the bridge block 300 and the insulation module 200, an assembly hole 340 adapted to the fastener 241 is specially provided on the bridge block 300. The assembly hole 340 penetrates the first bridge plate 310, the insulation plate 320 and the second bridge plate 330, so that the fastener 241 can be passed through the insulation module 200 and installed in the assembly hole 340. The first bridge plate 310 and the second bridge plate 330 can make the fixed connection of the bridge block 300 more stable and reliable.

[0085] The above structure not only makes the connection between the bridging block 300 and the insulation module 200 more stable and reliable, but also breaks through the thickness limitation faced by the traditional bridging block 300 when connecting the existing insulation module 200 through the corresponding structural design.

[0086] In addition, by providing the bridge block 300, the gap problem that may exist between two adjacent insulation modules 200 can be effectively solved, thereby avoiding the leakage of cold air. At the same time, the connection method using the fastener 241 further improves the connection stability between the bridge block 300 and the insulation module 200, ensuring the high efficiency performance and long-term reliability of the entire cryogenic storage tank enclosure system.

[0087] 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 structure 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 within 350 mm. With the setting of the bridging blocks 300, insulation modules 200 with greater thickness can be set, such as insulation modules 200 with thicknesses of 400 mm, 500 mm, 600 mm, etc. The specific thickness can be set as needed and is not limited to the above examples.

[0088] 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.

[0089] 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.

[0090] The heat insulation board 320 in the bridge block 300 is made of a material compatible with the heat insulation module 200 to ensure good heat conduction isolation effect while maintaining the integrity and strength of the structure. The combined use of the heat 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.

[0091] Furthermore, the shape and size of the insulation module 200 can be customized according to the specific conditions of the inner wall 100 of the storage tank to ensure that the insulation module 200 can fit closely to the inner wall 100 of the storage tank to reduce heat transfer.

[0092] Reference Figures 3 to 8 In some examples, the assembly hole 340 includes a first through portion 341 , a second through portion 342 , and a third through portion 343 . The first through portion 341 penetrates the first bridging plate 310 , the second through portion 342 penetrates the insulation plate 320 , and the third through portion 343 penetrates the second bridging plate 330 .

[0093] The cross-sectional size of the first through portion 341 is smaller than the cross-sectional sizes of the second through portion 342 and the third through portion 343 .

[0094] Such a design enables the assembly hole 340 to form a stepped structure in the bridge block 300, which is beneficial to enhancing the connection strength and stability of the bridge block 300. The smaller cross-sectional size of the first through-portion 341 facilitates the assembly of fasteners 241, such as bolts or screws, and the first bridge plate 310 is fixedly connected to the adjacent insulation module 200 or structural member through the first through-portion 341. The larger cross-sectional sizes of the second through-portion 342 and the third through-portion 343 provide sufficient space to facilitate the connection of the fasteners 241, so that the insulation board 320 can be firmly installed between the two bridge plates to ensure that the insulation effect is not destroyed. In addition, the design of such a stepped structure also helps to disperse the stress generated during the assembly process, further improving the durability and reliability of the bridge block 300.

[0095] In some examples, the assembly hole 340 is a circular hole, and the diameter of the first through-hole 341 is smaller than the diameters of the second through-hole 342 and the third through-hole 343 .

[0096] Alternatively, the assembly hole 340 is a square hole or a diamond hole, and the cross-sectional side length of the first through-hole 341 is smaller than the cross-sectional side lengths of the second through-hole 342 and the third through-hole 343 .

[0097] Such a design not only meets the assembly requirements, but also provides a variety of options for the bridge block 300. When the assembly hole 340 is a round hole, its smooth edge helps to reduce friction during the assembly process and reduce the risk of wear of the fastener 241. At the same time, the design of different hole diameters allows the fastener 241 to select a suitable size according to needs, ensuring the tightness and stability of the connection.

[0098] When the assembly hole 340 is a square hole or a diamond hole, the non-circular cross-sectional shape can more effectively resist shear force and improve the shear strength of the bridge block 300. In addition, the design of the square hole or diamond hole is also convenient for guiding the installation of the fastener 241 in a specific direction, making the assembly process more accurate and efficient.

[0099] Whether it is a round hole, a square hole or a diamond hole, the design of the assembly hole 340 fully considers the connection requirements and use environment of the bridge block 300, ensuring its reliability and durability in the fluid transportation equipment.

[0100] Reference Figures 3 to 8 In some examples, the fastener 241 passes through the first through portion 341 and is partially located in the second through portion 342 . The portion of the fastener 241 extending into the second through portion 342 is locked by a nut, which is tightened and abuts against the first bridging plate 310 .

[0101] This structure not only ensures that the fastener 241 is firmly installed in the bridge block 300, but also provides a convenient locking method. When the fastener 241 passes through the first through-portion 341 and enters the second through-portion 342, its length is sufficient to penetrate the two components and achieve an effective connection. Subsequently, the fastener 241 is locked in the second through-portion 342 by a nut, which not only enhances the stability of the connection, but also effectively prevents the fastener 241 from loosening due to vibration or external force.

[0102] In addition, the design of the nut being locked and abutted against the first bridge plate 310 further enhances the rigidity and durability of the connection. This abutment method not only disperses the force of the fastener 241 and reduces the load of a single part, but also improves the overall performance of the entire bridge structure.

[0103] Through the cooperation among the fastener 241 , the first through-portion 341 , the second through-portion 342 and the nut, a reliable connection between the bridging blocks 300 is achieved, providing a strong guarantee for the stable operation of the fluid transport equipment.

[0104] Reference Figures 3 to 8 In some examples, the cross-sectional size of the fastener 241 is smaller than the cross-sectional size of the first through-portion 341 , and there is a clearance space between the fastener 241 and the first through-portion 341 .

[0105] The cross-sectional dimension of the nut is greater than the cross-sectional dimension of the first through portion 341 , and when the fastener 241 and the first bridge plate 310 slide relative to each other, the nut always maintains a locked state.

[0106] This structure has multiple advantages. First, the cross-sectional size of the fastener 241 is smaller than the cross-sectional size of the first penetration portion 341, which provides sufficient space for the fastener 241 to move, and helps to achieve flexible operation during installation and adjustment. The existence of the clearance space not only simplifies the installation steps, but also allows the fastener 241 to be fine-tuned when necessary to ensure its precise positioning.

[0107] Secondly, the cross-sectional size of the nut is larger than the cross-sectional size of the first penetration portion 341. This design effectively prevents the nut from accidentally falling off during normal use. Even if relative slippage occurs between the fastener 241 and the first bridge plate 310, the nut can still remain locked due to its larger cross-sectional size, thereby maintaining the stability and safety of the connection.

[0108] The above-mentioned size design not only improves the overall performance of the bridging structure, but also provides a solid guarantee for the long-term stable operation of the fluid transportation equipment.

[0109] In some examples, at least one washer is sleeved on the fastener 241 , and the washer is located between the nut and the first bridge plate 310 .

[0110] The design of this gasket further enhances the stability and sealing of the bridge structure. The presence of the gasket can effectively fill the tiny gap between the nut and the first bridge plate 310, preventing the fluid from leaking through these gaps, thereby ensuring the sealing performance of the fluid transport equipment. In addition, the gasket can also play a role in buffering and shock absorption, reducing stress concentration caused by vibration or impact, and extending the service life of the fastener 241 and the bridge plate. In specific application scenarios, gaskets of different materials and thicknesses can be selected to meet different sealing and buffering requirements, thereby achieving customized optimization of the performance of the bridge structure.

[0111] There are many types of gaskets. According to the materials and occasions used, they can be mainly divided into three categories: non-metallic gaskets, semi-metallic gaskets and metallic gaskets. The following are the specific classifications: 1. Non-metallic gasket 1. Rubber gaskets: Common ones include rubber flat washers, rubber O-rings, etc., which are made of natural rubber, nitrile rubber, chloroprene rubber, etc. They have dense structure, soft texture, good resilience, easy to cut and process into various shapes, and cheap. However, they are not resistant to high pressure, easily dissolve and swell in mineral oil, are not corrosion-resistant, and are prone to aging and loss of resilience at high temperatures.

[0112] 2. Oil-resistant rubber gasket: It has excellent oil resistance and can maintain its sealing performance in an oily environment. It is usually used in an oily environment. The material cost is higher than that of ordinary rubber gaskets.

[0113] 3. Asbestos gasket: Made of asbestos fiber, rubber compounding agent, etc., it has good high temperature resistance (can withstand temperatures above 500°C), pressure resistance (can withstand pressures above 10MPa) and corrosion resistance (can withstand erosion by chemicals such as acids, alkalis, and salts). It is easy to customize and process, simple and convenient to install, and has high mechanical strength and compression resilience.

[0114] 4. Klinger gasket: a non-asbestos gasket material with similar properties to high-quality compressed asbestos gasket materials. It represents a compressed synthetic fiber material gasket with excellent sealing performance and can reliably prevent media leakage. The appropriate material and model can be selected according to different working conditions and media. It is easy to install and disassemble, reducing maintenance time and cost. It also has excellent chemical resistance and high high temperature resistance.

[0115] 5. Polytetrafluoroethylene gasket: It has extremely strong chemical stability and is one of the most corrosion-resistant materials in the world today. It can resist the erosion of most chemical corrosive media (including strong acids, strong alkalis, organic solvents, etc.), and maintain its stability and strength for a long time in high temperature environments (the operating temperature can reach 250℃ to 260℃). It also has good low-temperature resistance (it can maintain a certain mechanical toughness at temperatures of -196℃ to -180℃), and the sealing performance is stable and reliable.

[0116] 6. Graphite gasket: It is cut or stamped from pure graphite plate or metal mesh reinforced graphite plate. It has good compression resilience and plasticity, excellent sealing performance, and can work stably for a long time under high temperature, high pressure and strong corrosive environment.

[0117] 7. Red steel paper gasket: It uses red steel paper as the base material and is mainly composed of red steel paper, epoxy resin, glass fiber and other materials. It is strong and lightweight, with strength close to that of aluminum, but its specific gravity is only half of that of aluminum. It will not cause delamination and breakage, and has excellent oil resistance, electrical insulation performance and extremely high compressibility.

[0118] 8. Nylon gasket: Made of nylon 6 or nylon 66, it is a high-performance synthetic material with the characteristics of high strength, wear resistance and high temperature resistance. It has good elasticity and compressibility, can adapt to various complex application requirements, can maintain stable performance in friction and wear environments, and has good corrosion resistance to many chemicals.

[0119] 9. Silicone gasket: Made of silicone material, it has excellent high and low temperature resistance, corrosion resistance and softness. It is not easy to deform or age in high or low temperature environments. It can withstand the erosion of various acids, alkalis and organic solvents. It has certain flexibility and tension, and can adapt well to changes in equipment gaps to ensure sealing effect.

[0120] The above-mentioned polytetrafluoroethylene gasket still has sufficient performance in a low-temperature environment and can be applied to the enclosure system of the cryogenic storage tank of this application. Its excellent chemical corrosion resistance enables the polytetrafluoroethylene gasket to maintain good sealing performance when in contact with various corrosive media, effectively preventing fluid leakage. In addition, the polytetrafluoroethylene gasket also has good electrical insulation properties and a low friction coefficient, which gives it unique advantages in electrical equipment and applications that require reduced friction losses. Therefore, polytetrafluoroethylene gaskets are not only suitable for the enclosure system of cryogenic storage tanks, but are also widely used in various occasions that require high sealing, corrosion resistance and a low friction coefficient.

[0121] 2. Semi-metallic gasket Semi-metallic gaskets are usually made of a combination of metal and non-metallic materials, such as metal spiral wound gaskets, which combine the strength of metal and the sealing properties of non-metallic materials.

[0122] 3. Metal gasket Metal gaskets are mainly made of metal materials, such as stainless steel, copper, aluminum, etc., with high strength and good temperature and pressure resistance.

[0123] In summary, there are many types of gaskets. The specific type of gasket to be used needs to be considered comprehensively based on factors such as pressure, temperature, medium characteristics and sealing requirements in the actual application scenario.

[0124] In some examples, after the nut locks the fastener 241 , the second through-portion 342 and the third through-portion 343 are filled with a heat-insulating filler having a matching shape.

[0125] This insulating filler is designed to further reduce heat transfer and improve the thermal insulation performance of the cryogenic storage tank. The insulating filler is usually made of materials with low thermal conductivity, such as polyurethane foam, rock wool or aerogel, which can effectively block the conduction path of heat through the second penetration portion 342 and the third penetration portion 343. By accurately matching the shape of the insulating filler with the inner cavity of the penetration portion, it can be ensured that the filling is tight and seamless, and heat is prevented from penetrating through tiny gaps. In addition, the insulating filler can also enhance the structural strength between the fastener 241 and the bridge plate, making it more stable and reliable when subjected to thermal and mechanical stresses in a low temperature environment. This design not only improves the insulation efficiency of the cryogenic storage tank, but also provides strong support for the stable operation of fluid transportation equipment under extreme temperature conditions.

[0126] The first bridge plate 310 and the second bridge plate 330 are both made of plywood. The choice of plywood not only ensures the strength and stability of the bridge plate, but also has a certain high temperature resistance, and can resist the thermal deformation that may occur in a high temperature environment to a certain extent. The surface of the plywood can also be specially treated, such as coating with fire retardant coating, to further improve its fire resistance level and ensure that the structural integrity and sealing effect can be maintained under extreme working conditions.

[0127] Reference Fig. 9 and Fig.10 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 .

[0128] The first assembly plate 210 is connected to the inner wall 100 of the storage tank. The heat insulating body 220 is connected to the first assembly plate 210 and is located on the side of the first assembly plate 210 away from the inner wall 100 of the storage tank. The second assembly plate 230 is connected to the heat insulating body 220 and is located on the side of the heat insulating body 220 away from the first assembly plate 210, and the fastener 241 is installed on the second assembly plate 230.

[0129] After the fastener 241 is installed on the second assembly plate 230 , the stability and firmness of the entire thermal insulation module 200 can be ensured.

[0130] 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.

[0131] 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.

[0132] The first assembly plate 210 and the second assembly plate 230 can be made of plywood or other low-temperature resistant plate-like structures. Such materials not only have sufficient strength and stability, but also can maintain their performance without deformation in a low-temperature environment, thereby ensuring the overall effectiveness of the insulation module 200. Due to its multi-layer structure, plywood has good bending strength and stability, and can withstand certain pressure and load, ensuring that the insulation module 200 is not easily deformed or damaged during installation and use.

[0133] In 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.

[0134] 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 .

[0135] 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 . The second assembly sub-plate 232 is disposed in the avoidance groove 261 . The fastener 241 is installed on the second assembly sub-plate 232 .

[0136] This structure not only enhances the structural strength of the insulation module 200, but also improves its assembly flexibility. When multiple insulation modules 200 need to be connected, the design of the avoidance groove 261 makes it easier to assemble adjacent insulation modules 200. Only two avoidance grooves 261 need to be aligned and spliced ​​to form a complete assembly groove 260, which is convenient for the installation of the fastener 241.

[0137] The combination of the second assembly main board 231 and the second assembly sub-board 232 further improves the stability of the insulation module 200. The second assembly main board 231 serves as the main supporting structure, ensuring the stability of the insulation module 200 during installation and use. The second assembly sub-board 232 is cleverly arranged in the avoidance groove 261, which not only does not affect the overall appearance of the insulation module 200, but also provides an installation position for the fastener 241, making the connection between the insulation modules 200 tighter and more reliable.

[0138] In addition, this structure also takes into account the heat dissipation performance of the heat insulation module 200. The setting of the avoidance groove 261 increases the heat dissipation area on the surface of the heat insulation module 200, which is conducive to the dissipation of heat and improves the heat dissipation efficiency of the heat insulation module 200. At the same time, the existence of the second assembly sub-plate 232 also plays a certain heat dissipation role, further enhancing the heat dissipation performance of the heat insulation module 200.

[0139] In some examples, at least one mounting seat 240 is disposed on the second assembly sub-plate 232 , and each mounting seat 240 is disposed with a fastener 241 , which passes through the bridging block 300 and is anchored to the bridging block 300 .

[0140] This structure not only enhances the connection strength between the insulation modules 200, but also ensures the stability and accuracy of the fasteners 241 during the installation process. The setting of the mounting seat 240 provides a stable support point for the fasteners 241, avoiding the problem of failure of the insulation module 200 connection due to the loosening of the fasteners 241. At the same time, the fasteners 241 pass through the bridging block 300 and are anchored to the bridging block 300. This connection method further enhances the overall stability and reliability of the insulation module 200. As a key component connecting two insulation modules 200, the strength and stability of the bridging block 300 are of vital importance. Through this structure, a firm connection is formed between the bridging block 300 and the fasteners 241, which effectively transmits the force and torque between the insulation modules 200, thereby ensuring the stability and safety of the entire insulation system.

[0141] In some examples, a receiving groove matched with the mounting seat 240 is formed on the second assembly sub-plate 232 , and the mounting seat 240 is embedded in the receiving groove.

[0142] It can be ensured that the mounting seat 240 will not protrude too much from the surface of the second assembly sub-plate 232 after installation, and the mounting seat 240 can be limited by the receiving groove to improve the installation stability.

[0143] This structure not only optimizes the appearance of the insulation module 200, reduces the risk of collision or damage caused by the protrusion of the mounting seat 240, but also ensures the precise alignment of the mounting seat 240 during the installation process through the limiting effect of the receiving groove, avoiding the problem of unstable connection caused by position deviation. In addition, the close fit between the receiving groove and the mounting seat 240 also effectively prevents the external environment from corroding the mounting seat 240, and prolongs the service life of the fastener 241 and the entire insulation module 200. This refined design reflects the high attention and control of the connection details of the insulation module 200, and further improves the overall performance and reliability of the insulation system.

[0144] In some examples, the mounting base 240 is fixedly connected to the second assembly sub-board 232, and the fixing method includes at least one of bonding, clamping, magnetic attraction, and connection with a fixing piece.

[0145] Such fixing methods are flexible and diverse in design, and can meet the installation requirements in different application scenarios. The bonding method is suitable for scenarios that require strong connection force and good sealing. The mounting seat 240 is firmly attached to the second assembly sub-plate 232 through a special adhesive to ensure that the connection is stable and not easy to fall off. The snap-on method is convenient for quick installation and disassembly. Through the cleverly designed snap-on structure, the convenient connection between the mounting seat 240 and the second assembly sub-plate 232 is realized, thereby improving the assembly efficiency. The magnetic suction method is suitable for scenarios where the position of the mounting seat 240 needs to be frequently replaced or adjusted. The principle of magnetic adsorption is used to realize the flexible positioning of the mounting seat 240. The fixing part connection method provides a more reliable mechanical connection. The mounting seat 240 is firmly fixed to the second assembly sub-plate 232 through fasteners 241 such as bolts and nuts, which is suitable for environments with large loads or large vibrations. The flexible use of these fixing methods not only improves the stability and reliability of the mounting seat 240, but also provides users with more diverse installation options, and enhances the adaptability and flexibility of the cryogenic storage tank containment system and fluid transportation equipment.

[0146] In some examples, fixing holes are respectively opened at the four corners of the mounting seat 240, and the mounting seat 240 is connected to the second assembly through a fixing piece, and the fixing piece fixes the mounting seat 240 to the second assembly sub-plate 232 through the fixing holes.

[0147] This structure not only enhances the stability of the connection, but also facilitates precise positioning during the installation process. The setting of the fixing holes enables the fixings to be evenly distributed, thereby dispersing the force on the connection points and improving the overall load-bearing capacity and safety. At the same time, fixing through the fixing holes can also effectively prevent the mounting base 240 from deformation or loosening due to uneven force during long-term use. In addition, this fixing method is also convenient for subsequent maintenance and inspection work, because the fixings are usually easy to disassemble and reinstall without destroying the original connection structure. Therefore, this design of connecting the mounting base 240 and the second assembly sub-plate 232 using fixing holes and fixings not only improves the reliability and durability of the product, but also brings great convenience to the user's operation and maintenance.

[0148] In some examples, the fixing member includes at least one of a screw, a rivet, and an expansion screw for fixing connection.

[0149] The choice of these fixings depends on the specific application scenario and requirements. For example, screws are often used to connect components that require frequent maintenance or inspection because they are easy to remove and reinstall. Rivets are more suitable for situations that require higher strength and permanent connections because they are difficult to remove once installed, providing a more stable connection. Expansion screws are often used in scenarios where they need to be fixed on softer or fragile materials. They generate friction by expanding to achieve a firm fixation effect. Choosing appropriate fixings not only ensures the safety and stability of the connection, but also improves the overall assembly efficiency and maintainability. Therefore, during the design and manufacturing process, it is crucial to select appropriate fixings according to actual needs.

[0150] Reference Fig. 9 and Fig.10 The enclosure system further includes a shielding module 400 , which is connected to the thermal insulation module 200 .

[0151] In a second aspect, 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 enclosure system of the cryogenic storage tank as described above.

[0153] 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 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.

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.

[0155] 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.

[0156] 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.

[0157] The design of this fluid transportation equipment fully considers the thermal insulation performance and safety of the cryogenic tank. By applying the cryogenic tank enclosure system as described above to the cryogenic tank, it ensures that the tank can maintain efficient thermal insulation under various transportation conditions, preventing the stored materials from being damaged or dangerous due to temperature changes. The integrated design of the equipment body and the cryogenic tank not only improves the stability of the overall structure, but also optimizes the use of space, making fluid transportation more efficient and economical.
