Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, and in particular to a modular air-supported membrane cold storage that can be rapidly assembled. Background Technology

[0002] Modular air-supported membrane cold storage is a new type of cold chain facility that uses a modular air-supported membrane structure. Its core advantage lies in the ability to quickly assemble the components using pre-produced standardized air-supported membrane units and frame components in a "building block" manner. This type of cold storage is suitable for scenarios such as emergency storage of agricultural products, cold chain transportation and transshipment of vaccines, and preservation of disaster relief supplies. It also features efficient construction, low-carbon operation, and recyclability.

[0003] An investigation revealed that Chinese utility model patent CN219863325U discloses a modular air-supported membrane warehouse, comprising air-supported membrane units and end door modules. The air-supported membrane units are strip-shaped components with an arched cross-section along their width. Multiple air-supported membrane units are arranged in a row along their respective width directions and are connected and fixed to each other. Each air-supported membrane unit is anchored to the ground. A channel connecting the inner cavities of two adjacent air-supported membrane units is provided. Both ends of the air-supported membrane units are open in the length direction. Airbag clamping assemblies are provided at both ends of the air-supported membrane units. Each airbag clamping assembly is detachably equipped with an end door module for sealing the open end of the air-supported membrane unit. The end door module has a door and a window that can be opened or closed. The arched structure increases the usable area and improves space utilization. Furthermore, the rigid end door module structure solves the problem of the difficulty in shaping the end door of the airbag structure and increases the functional expansion of the door.

[0004] However, the assembly of the aforementioned air-supported membrane cold storage requires professional and complex assembly operations to assemble the modular air-supported membrane warehouse. For use scenarios such as emergency storage of agricultural products that require rapid disassembly and installation, the complex assembly operations often cause inconvenience to users. The time spent on installation directly affects the efficiency of cold storage. Furthermore, the interior of the assembled cold storage cannot be connected, resulting in a waste of internal space. The partitioned spaces after assembly also cause inconvenience for goods entering and leaving the warehouse.

[0005] Therefore, a modular air-supported membrane cold storage system that can be quickly prototyped is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapidly prototyping modular air-supported membrane cold storage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rapidly prototyping modular air-supported membrane cold storage includes a front airbag and a rear airbag. A door is mounted on the front airbag, and a refrigeration unit is mounted on the rear airbag. Several connecting airbags are arranged between the front and rear airbags. Air valves are fixedly installed on the front, rear, and connecting airbags. A snap-fit ​​portion connected to the front airbag at the end furthest from the door and a hemispherical embedded portion connected to the connecting airbag at the end furthest from the front airbag are both fixedly installed. An embedding portion connected to the rear airbag at the end furthest from the refrigeration unit and a hemispherical embedded portion adapted to the connecting airbag are also fixedly installed. The snap-fit ​​portion is a C-shaped fixing airbag, and the embedding portion is a hemispherical embedding airbag adapted to the C-shaped fixing airbag. A communication mechanism is provided between the snap-fit ​​portion and the embedding portion.

[0009] Preferably, the communication mechanism includes a communication tube fixedly installed on the embedded airbag and passing through the embedded airbag, a fixed tube fixedly installed on the C-shaped fixed airbag and communicating with it, and a communication port opened on the fixed tube. A sealing plate is slidably installed inside the fixed tube, and an adjustment mechanism is provided between the sealing plate and the fixed tube. The inner diameter of the communication tube is slightly smaller than the outer diameter of the fixed tube.

[0010] Preferably, the inner wall of the connecting tube has a plurality of annular grooves arranged in a linear array, and the end of the fixing tube near the C-shaped fixing airbag is fixedly installed with a plurality of annular protrusions that are adapted to the annular grooves.

[0011] Preferably, a limiting airbag connected to the fixed tube is fixedly installed on the fixed tube. The limiting airbag is disposed between the connecting port and the annular protrusion, and the distance between the limiting airbag and the C-shaped fixed airbag is greater than the length of the connecting tube.

[0012] Preferably, the adjusting mechanism includes a threaded sleeve rotatably mounted at one end of the fixed tube, a threaded rod threadedly mounted in the threaded sleeve, and a guide groove formed on the inner side wall of the fixed tube. A sliding plate that is slidably connected to the guide groove is fixedly mounted at one end of the threaded rod located inside the fixed tube, and a spring is fixedly mounted between the sliding plate and the sealing plate.

[0013] Preferably, a plurality of positioning plates are uniformly fixedly installed on the C-shaped fixed airbag, and a plurality of positioning blocks adapted to the positioning plates are uniformly fixedly installed on the embedded airbag. Both the positioning plates and the positioning blocks are made of magnetic material.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting C-shaped fixed airbags, embedded airbags and connecting airbags, the appropriate number of connecting airbags can be flexibly selected according to actual usage needs. The embedded airbags are fixed and wrapped by the C-shaped fixed airbags, and the air pressure is used to tightly squeeze to achieve a sealed connection between the head airbag and the connecting airbags, which greatly shortens the installation time of the air-supported membrane cold storage and achieves rapid installation.

[0016] 2. By setting up connecting pipes and fixing pipes, you only need to open the air valve on the first airbag and fill it with gas. The gas will automatically fill each module in sequence, eliminating the need to inflate each airbag individually. This simplifies the assembly process and improves assembly efficiency. The annular groove and annular protrusion increase the friction at the connection point, and the limiting airbag will expand first inside the embedded airbag and then lock the connecting pipe, ensuring the stability of the inflation and installation process. This effectively avoids the situation where the interface cannot be separated due to air pressure difference, thus preventing smooth installation.

[0017] 3. By rotating the threaded sleeve to drive the threaded rod, the distance between the sliding plate and the connecting port is adjusted, thereby changing the pressure required for the sealing plate to move to the connecting port. This allows the C-type fixed airbag to be inflated before the embedded airbag connected to it, and the embedded airbag to expand only after the internal air pressure reaches a certain level. This ensures that the embedded airbag can be stably installed in place. Combined with the pre-positioning function of the magnetic positioning plate and positioning block, the installation process is fully automated and unmanned, reducing errors and labor intensity of manual operation, and improving installation quality and efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 A rapidly prototyping modular air-supported membrane cold storage includes a front airbag 1 and a rear airbag 2. A door 21 is mounted on the front airbag 1, and a refrigeration unit 22 is mounted on the rear airbag 2. Several connecting airbags 3 are arranged between the front airbag 1 and the rear airbag 2. Air valves 31 are fixedly installed on the front airbag 1, the rear airbag 2, and the connecting airbags 3. A snap-fit ​​part is fixedly installed at the end of the front airbag 1 away from the door 21 and at the end of the connecting airbag 3 away from the front airbag 1, communicating with it. The end of the rear airbag 2 away from the refrigeration unit 22 and the connecting airbag 3 are also fixedly installed with... Each end of the connecting airbag 3 away from the tail airbag 2 is fixedly installed with an embedded part that communicates with it. The snap-fit ​​part is a C-shaped fixed airbag 32, and the embedded part is a hemispherical embedded airbag 33 that is adapted to the C-shaped fixed airbag 32. A communication mechanism is provided between the snap-fit ​​part and the embedded part. According to the actual use requirements, an appropriate number of connecting airbags 3 can be flexibly selected. The embedded airbag 33 is fixedly wrapped by the C-shaped fixed airbag 32. The sealing connection can be achieved by simply filling it with gas, which greatly shortens the installation time of the air-supported membrane cold storage and achieves rapid installation.

[0028] Reference Figures 3 to 6The connecting mechanism includes a connecting pipe 4 fixedly installed on and through the embedded airbag 33, a fixed pipe 41 fixedly installed on and connected to the C-shaped fixed airbag 32, and a connecting port 48 opened on the fixed pipe 41. A sealing plate 47 is slidably installed inside the fixed pipe 41. An adjustment mechanism is provided between the sealing plate 47 and the fixed pipe 41. The inner diameter of the connecting pipe 4 is slightly smaller than the outer diameter of the fixed pipe 41. As long as the air valve 31 on the head airbag 1 is opened and gas is filled in, the gas will automatically pass through the passage formed by the fixed pipe 41 and the connecting pipe 4 in sequence through each connecting airbag 3 and the tail airbag 2. There is no need to inflate each airbag individually, which simplifies the construction steps, improves the construction efficiency, and ensures a high-quality construction effect.

[0029] Reference Figure 5 The inner wall of the connecting pipe 4 has several annular grooves 5 arranged in a linear array. The end of the fixing pipe 41 near the C-shaped fixing airbag 32 is fixedly installed with several annular protrusions 51 that are adapted to the annular grooves 5. The annular grooves 5 and the annular protrusions 51 increase the friction between the fixing pipe 41 and the connecting pipe 4, effectively avoiding the situation where the interface cannot be separated due to air pressure difference and thus ensuring the stability of the connection structure.

[0030] Reference Figure 5 and Figure 6 A limiting airbag 52 is fixedly installed on the fixed tube 41. The limiting airbag 52 is located between the connecting port 48 and the annular protrusion 51, and the distance between the limiting airbag 52 and the C-shaped fixed airbag 32 is greater than the length of the connecting tube 4. During the process of gas filling from the first airbag 1 to the tail airbag 2, when the gas enters the next module, the limiting airbag 52 will first expand inside the embedded airbag 33 and then block the connecting tube 4, preventing the connecting tube 4 from separating from the fixed tube 41, thus ensuring the stable progress of the inflation and installation process.

[0031] Reference Figure 5 and Figure 6 The adjustment mechanism includes a threaded sleeve 42 rotatably mounted on one end of the fixed tube 41, a threaded rod 43 threaded inside the threaded sleeve 42, and a guide groove 45 formed on the inner wall of the fixed tube 41. A sliding plate 44, which is slidably connected to the guide groove 45, is fixedly mounted on one end of the threaded rod 43 inside the fixed tube 41. A spring 46 is fixedly mounted between the sliding plate 44 and the sealing plate 47. The threaded sleeve 42 drives the threaded rod 43 to move. Under the action of the guide groove 45, the sliding plate 44 moves linearly, thereby adjusting the distance between the sliding plate 44 and the connecting port 48. This changes the pressure required for the sealing plate 47 to move to the connecting port 48, allowing the C-shaped fixed airbag 32 to be inflated before the embedded airbag 33 connected to it. The embedded airbag 33 will only expand after the internal air pressure reaches a certain level, ensuring that the embedded airbag 33 can be stably installed in place.

[0032] Reference Figure 3 and Figure 4 Several positioning plates 6 are evenly fixedly installed on the C-shaped fixed airbag 32, and several positioning blocks 61 that are compatible with the positioning plates 6 are evenly fixedly installed on the embedded airbag 33. Both the positioning plates 6 and the positioning blocks 61 are made of magnetic material. Combined with the pre-positioning function of the magnetic positioning plates 6 and the positioning blocks 61, the installation process is fully automated and unmanned, reducing the error and labor intensity of manual operation, and improving the installation quality and efficiency.

[0033] The specific working principle of this utility model is as follows:

[0034] In use, the appropriate number of connecting airbags 3 can be selected according to actual needs, and the first airbag 1, the tail airbag 2 and the connecting airbag 3 can be connected in sequence. When the airbags are inflated, the first airbag 1 and the first connecting airbag 3 are fixed and wrapped by the C-shaped fixing airbag 32. After being tightly squeezed by air pressure, the sealing connection between the first airbag 1 and the connecting airbag 3 can be achieved. Similarly, the sealing connection between each module can be achieved by simply filling each connecting airbag 3 and the tail airbag 2 with gas, so as to realize the rapid installation and formation of the air-supported cold storage.

[0035] By inserting the sequentially connected fixed tubes 41 into the corresponding connecting tubes 4, it is possible to simply open the air valve 31 on the first airbag 1 and inflate it with gas. The gas will then automatically pass through the passage formed by the fixed tubes 41 and the connecting tubes 4, sequentially through each connecting airbag 3 and the tail airbag 2, achieving rapid overall construction of the air-supported membrane cold storage. This greatly simplifies the construction steps, improves construction efficiency, and ensures high-quality construction results. The annular groove 5 and the annular protrusion 51 can increase the friction between the fixed tubes 41 and the connecting tubes 4, preventing the interface from separating due to air pressure differences and hindering installation. Furthermore, by setting the limiting airbag 52, it is possible to ensure that when the gas is sequentially inflated from the first airbag 1 to the tail airbag 2, the limiting airbag 52 will first expand inside the embedded airbag 33 and then lock the connecting tube 4, ensuring that the connecting tube 4 and the fixed tube 41 will not separate, thus ensuring stable inflation and installation.

[0036] By rotating the threaded sleeve 42, the threaded rod 43 can be driven to move. Under the action of the guide groove 45, the threaded rod 43 drives the slide plate 44 to move linearly, thereby adjusting the distance between the slide plate 44 and the connecting port 48. This changes the pressure required for the sealing plate 47 to move to the connecting port 48. With proper settings, the C-shaped fixed airbag 32 can be inflated before the embedded airbag 33 connected to it. The embedded airbag 33 will only expand after the internal air pressure reaches a certain level, ensuring that the embedded airbag 33 can be stably installed in place. Combined with the pre-positioning function of the magnetic positioning plate 6 and the positioning block 61, the installation process can be fully automated and unmanned, and the cold storage can be stably and efficiently installed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
