Description

[0002] With the increase in the scale and collectivization of agriculture and breeding, the demand for refrigerated storage is also increasing. Traditional cold storage buildings are difficult to build directly in source production areas such as orchards due to high costs and long construction periods. Farmers are usually required to transport the picked products to centralized cold storage points. In addition, the source production areas are generally located in remote areas with poor transportation infrastructure, resulting in serious losses during transportation, which seriously affects the profitability of farmers. The air membrane system has relatively low cost and fast construction speed, but the thermal insulation capacity of the air membrane system is an important factor that limits its cold storage capacity. Although some air membrane systems with insulation layers have been proposed in the prior art, these air membrane systems with insulation layers are usually air-supported structures. However, the air-supported structure requires continuous inflation to support the membrane cloth to maintain rigidity, and the energy consumption is relatively large, which is too costly for farmers. The cost of the air-rib structure is lower than that of the air-supported structure. However, the air-rib structure requires air to be inflated in the middle of the air ribs. The air-rib structure in the prior art is usually a single-layer structure, and it is difficult to set up an insulation layer.

[0050] Example 1

[0051] This embodiment provides a gas pleural membrane system for cold storage, referring to Figure 1 As shown, it includes an air rib arch group, an outer film layer 1, an inner film layer 2, a flexible thermal insulation layer 3 and a pull rope 4.

[0052] Reference Figure 2 As shown, the air rib arch group includes a plurality of air rib cavities 5. After being inflated, the air rib cavity 5 extends from one end to the other end and forms an arch shape. A plurality of independent air rib cavities 5 are arranged in a direction perpendicular to the arch surface of the air rib cavity 5. The outer coating layer 1 covers the outer side of the air rib arch group, and the outer coating layer 1 spans all the air rib cavities 5, providing waterproof, heat-insulating and protective effects for the air rib body cavity. The inner coating material covers the inner side of the air rib arch group, and the inner coating layer 2 also spans all the air rib cavities 5, preventing the intrusion of internal water vapor and the like, and also has a thermal insulation effect. The flexible thermal insulation layer 3 is located between the air rib arch group and the inner coating layer 2. The flexible thermal insulation layer 3 bends with the arch shape of the air rib cavity 5. The flexible thermal insulation layer 3 is a block structure and extends continuously along the arrangement direction of the air rib cavity 5 to form a flexible thermal insulation layer 3 as a whole. The pull rope 4 connects the outer film layer 1 and the inner film layer 2, and the pull rope 4 passes between adjacent air rib cavities 5 and penetrates the flexible thermal insulation layer 3. The gravity of the flexible thermal insulation layer 3 is borne by the inner film layer 2, and the inner film layer 2 and the outer film layer 1 are connected by the pull rope 4, so that the gravity of the flexible thermal insulation layer 3 is converted to the outer film layer 1, and finally borne by the air rib cavity 5, so as to ensure the installation and support of the flexible thermal insulation layer 3. By using multiple pull ropes 4 arranged along the extension direction of the air rib cavity 5, the uniform distribution of the gravity of the flexible thermal insulation layer 3 is ensured.

[0053] By setting the inner coating layer 2, the flexible thermal insulation layer 3 can be effectively supported as a whole, and the surface of the flexible thermal insulation layer 3 can be shaped to ensure that the surface of the flexible thermal insulation layer 3 is flat and fits the air rib cavity 5, thereby ensuring that the flexible thermal insulation layer 3 has uniform thermal insulation capacity and avoiding the occurrence of cold bridge phenomenon.

[0054] The air membrane system with an air rib structure only needs to inflate the air rib cavity 5 to maintain the rigidity of the structure, and does not require continuous inflation. It has low energy consumption and low cost, and is more suitable for cold storage warehouses that are the source of fresh products such as orchards.

[0055] The air rib membrane system for cold storage provided in this embodiment transfers the gravity of the insulation layer to the outer film layer 1 through the pull rope 4, and then the air rib cavity 5 carries the weight, thereby realizing the installation of the insulation layer and ensuring the full coverage of the insulation layer. By passing the pull rope 4 through the adjacent air rib cavity 5 and the insulation layer, the insulation layer is uniformly loaded, and the air rib cavity 5 and the insulation layer can be constrained and limited, thereby ensuring the stability of the overall structure.

[0056] Specifically, refer to Figure 2 As shown, as an arrangement of the pull rope 4 in this embodiment, a first buckle 6 is provided on the outer film layer 1, and a second buckle 7 is provided on the inner film layer 2, the first buckle 6 is aligned with the second buckle 7 and both are located in the gap between adjacent air rib cavities 5; the two ends of the pull rope 4 are respectively connected to the first buckle 6 and the second buckle 7 by hooks; that is, the pull rope 4 is respectively connected to the first buckle 6 and the second buckle 7 in a linear manner, and the installation process is more convenient and quick.

[0057] Specifically, as another arrangement of the pull rope 4 in this embodiment, refer to Figure 3 As shown, the outer film layer 1 is provided with a first buckle 6, and the inner film layer 2 is provided with a second buckle 7, and the first buckle 6 and the second buckle 7 are arranged staggered. The end of the pull rope 4 is provided with a hook, and the hook is connected to the first buckle 6 or the second buckle 7. The pull rope 4 is connected to the inner film layer 2 and the outer film layer 1 through the hook, which makes the installation process of the air rib membrane system more convenient.

[0058] The pull rope 4 is divided into a plurality of pull rope segments, each of which is provided with hooks at both ends and connected to the first buckle 6 or the second buckle 7 through the hooks. Two pull rope segments are provided between two adjacent air rib cavities 5. Specifically, there are at least two winding methods for the pull rope segments.

[0059] One of the references Figure 3 As shown, the first buckle 6 is aligned with the center position of the air rib cavity 5, and the second buckle 7 is aligned with the gap position between adjacent air rib cavities 5, so that one end of the two pull rope segments located between two adjacent air rib cavities 5 are respectively connected to two different first buckles 6, and the other end is connected to the same second buckle 7.

[0060] The second reference Figure 4As shown, the first buckle 6 is aligned with the gap position of adjacent air rib cavities 5, and the second buckle 7 is aligned with the center position of the air rib cavity 5, so that one end of the two pull rope sections between two adjacent air rib cavities 5 is connected to the same first buckle 6, and the other end is connected to two different first buckles 6 respectively.

[0061] By adopting the above two methods, the pull rope segment is formed into a continuous state from beginning to end, and the pull rope segment is tensioned by the air rib cavity 5. A buckle is connected to two pull ropes 4 respectively, so that the tension distribution is more uniform, and the integrity of each part makes the overall structure more stable.

[0062] Specifically, in this embodiment, refer to Figure 5 As shown, the flexible thermal insulation layer 3 includes multiple thermal insulation unit layers stacked up and down, and the thermal insulation unit layer includes multiple thermal insulation unit blocks 8 arranged in the horizontal direction, and the thermal insulation unit blocks 8 between different thermal insulation unit layers are staggered; a hose 24 for accommodating the pull rope 4 to pass through is provided in the flexible thermal insulation layer 3, and the hose 24 is made of soft material to prevent the pull rope 4 from cutting the flexible thermal insulation layer 3 and causing damage. By staggering the thermal insulation unit blocks 8, the through seams are reduced, thereby increasing the airtightness and reducing the air leakage.

[0063] Specifically, continue to refer to Figure 3 As shown, one side of the air rib cavity 5 is buckled with the outer film layer 1, and the other side is buckled with the flexible thermal insulation layer 3. In a different manner, the air rib cavity 5 and the drawstring 4 can also share the first buckle 6.

[0064] Specifically, refer to Figure 1 As shown, it also includes a floor layer 9 and a side insulation layer 10. Figure 6 As shown, the floor layer 9 includes, from top to bottom, a heat-insulating floor 11, a concrete surface layer 12, a steel mesh layer 13, an upper moisture-proof plastic layer 14, an extruded board insulation layer 15, a lower moisture-proof plastic layer 16, a cement mortar leveling layer 17, a concrete floor 18, a crushed stone cushion layer 19 and a plain soil ramming layer 20. The lower moisture-proof plastic layer 16, the cement mortar leveling layer 17, the concrete floor 18, the crushed stone cushion layer 19 and the plain soil ramming layer 20 provide a good foundation for the hardened ground conditions of the air ventilating membrane gas. The concrete surface layer 12 and the steel mesh layer 13 are used for load bearing, and the heat-insulating floor 11, the upper moisture-proof plastic layer 14 and the extruded board insulation layer 15 are used to enhance the insulation effect.

[0065] In order to reduce cold air leakage and improve the thermal insulation effect, the side insulation layer 10 is attached to the side of the floor layer 9 and extends to the outside of the outer film layer 1. The gap between the air rib cavity 5 and the floor layer 9 is sealed.

[0066] Specifically, continue to refer to Figure 1As shown, it also includes a constant pressure inflation system 21, a refrigeration system 22 in the cold storage warehouse, and a refrigeration system 23 in the air rib cavity. The constant pressure inflation system 21 is connected to the air rib cavity 5, and the pressure in the air rib cavity 5 is monitored by a sensor, and the constant pressure inflation system 21 is controlled to keep the air rib cavity 5 at a constant pressure. The refrigeration system 22 in the cold storage warehouse is connected to the cold storage warehouse through a pipeline to provide cold air for the cold storage warehouse. In order to reduce heat loss, the pipeline can be passed from the underground into the cold storage warehouse. The refrigeration system 23 in the air rib cavity is connected to the air rib cavity 5 to control the temperature in the air rib cavity 5, thereby further reducing the temperature in the cold storage warehouse. The refrigeration system 23 in the air rib cavity can also be connected to the cold storage warehouse to provide cold air for the cold storage warehouse.

Compared with Example 1, this embodiment does not have an inner film layer 2.

[0075] Reference Fig.10As shown, the air rib arch group includes a plurality of air rib cavities 5. After being inflated, the air rib cavity 5 extends from one end to the other end and forms an arch shape. A plurality of independent air rib cavities 5 are arranged in a direction perpendicular to the arch surface of the air rib cavity 5. The outer coating layer 1 covers the outside of the air rib arch group, and the outer coating layer 1 spans all the air rib cavities 5, providing waterproof, heat-insulating and protective functions for the air rib body cavity. The flexible thermal insulation layer 3 bends along the arch shape of the air rib cavity 5. The flexible thermal insulation layer 3 is a block structure and extends continuously along the arrangement direction of the air rib cavity 5 to form a flexible thermal insulation layer 3 as a whole. The pull rope 4 connects the outer coating layer 1 and the flexible thermal insulation layer 3, and the pull rope 4 passes between adjacent air rib cavities 5. The gravity of the flexible thermal insulation layer 3 is evenly transferred to the outer coating layer 1 through the pull rope 4, and is finally borne by the air rib cavity 5. Ensure the installation and support of the flexible thermal insulation layer 3. By arranging a plurality of pull ropes 4 along the extension direction of the air rib cavity 5 , uniform distribution of gravity on the flexible thermal insulation layer 3 is ensured.

[0076] The air membrane system with an air rib structure only needs to inflate the air rib cavity 5 to maintain the rigidity of the structure, and does not require continuous inflation. It has low energy consumption and low cost, and is more suitable for cold storage warehouses that are the source of fresh products such as orchards.

[0077] The air rib membrane system for cold storage provided in this embodiment transfers the gravity of the insulation layer to the outer film layer 1 through the pull rope 4, and then the air rib cavity 5 carries the weight, thereby realizing the installation of the insulation layer and ensuring the full coverage of the insulation layer. By passing the pull rope 4 through the adjacent air rib cavity 5 and the insulation layer, the insulation layer is uniformly loaded, and the air rib cavity 5 and the insulation layer can be constrained and limited, thereby ensuring the stability of the overall structure.

[0078] Specifically, continue to refer to Fig.10 As shown, the outer film layer 1 is provided with a first buckle 6, the flexible thermal insulation layer 3 is provided with a second buckle 7, and the end of the drawstring 4 is provided with a hook, which is connected to the first buckle 6 or the second buckle 7.

[0086] Inflate the air rib cavity 5 to form the air rib cavity 5;

When installing each flexible thermal insulation layer 3, the pull rope 4 is passed through the flexible thermal insulation layer 3 and connected to the inner coating layer 2 to make the flexible thermal insulation layer 3 fit the air rib cavity 5; each flexible thermal insulation layer 3 is installed in sequence.

[0088] By placing the outer film layer 1 on the uninflated air rib cavity 5, the outer film layer 1 is directly propped up after inflation, thereby reducing the subsequent installation steps of the outer film layer 1.

At this time, the inner film layer 2 connected to the pull rope 4 supports the corresponding flexible thermal insulation layer 3. During the installation process, there is no need to additionally position and temporarily support the flexible thermal insulation layer 3, which simplifies the installation process.
