Description

Technical Field

[0001] This utility model relates to the field of cold storage equipment technology, specifically to a cold storage box fixing component for cold storage and a cold storage including the component. Background Technology

[0002] In the modern cold chain logistics and food preservation industry, cold storage plays an indispensable role. As the core infrastructure for low-temperature warehousing, these buildings create a suitable low-temperature storage environment for various goods. Currently, compression refrigeration units have become the mainstream choice for cold storage refrigeration due to their mature technology. However, this has led to enormous electricity consumption. Data shows that electricity used for cold storage refrigeration accounts for more than 20% of the total electricity consumption in society, making energy conservation and emission reduction an urgent priority.

[0003] Traditional cold storage operations rely on refrigeration compressor units working continuously to deliver cooling energy into the storage area via air coolers, thereby maintaining stable low-temperature conditions. However, this operating mechanism has significant shortcomings. During peak summer electricity consumption periods or in situations where power supply is unstable during long-distance transportation, the cooling capacity of the refrigeration units will be greatly reduced, and the temperature inside the storage area will become uncontrollable, directly threatening the quality of the stored goods.

[0004] To address energy consumption issues, cold storage technology has emerged, aiming to store cold energy during off-peak hours for use during peak hours. However, traditional cold storage methods mostly use water-based cold storage, which requires large equipment footprints, has limited storage capacity, and a small temperature difference, severely limiting its applicability and hindering its widespread adoption in industrial production. Even some patented devices attempting to apply cold storage materials to cold storage facilities have failed to achieve widespread application due to complex structures and installation difficulties.

[0005] The cold storage device described in Reference 1:

[0006] Reference 1: Chinese patent document with publication number CN 216432194 U

[0007] Reference 1 describes a cold storage device and cold storage facility, comprising K×N cold storage units and N air-cooling units, where K and N are both positive integers. Each cold storage unit includes a support frame and multiple cold storage plates. Each cold storage plate includes a shell and cold storage material filled within the shell. Assembly holes are provided through the shell. The support frame passes sequentially through the assembly holes of the multiple cold storage plates to fix them, forming a cold storage unit. Air-cooling units are used to blow air onto the cold storage plates to increase the rate at which the cold storage plates store or release cold energy. The cold storage facility includes the aforementioned cold storage device and also includes A rows of shelves. There are A cold storage devices, each installed on one of the A rows of shelves. Items are placed between adjacent rows of shelves, where A is a positive integer greater than or equal to 2. This cold storage device can reduce temperature fluctuations within the cold storage facility, providing a stable storage environment for the items inside.

[0008] Although the cold storage device in Reference 1 can reduce temperature fluctuations in the cold storage and provide a stable storage environment, it has the drawback of low space utilization. Its cold storage plate is only set on the shelf and fails to make full use of other spaces in the cold storage. Utility Model Content

[0047] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0048] <Example 1>

[0049] A cold storage box fixing assembly includes a cold storage box connector and a lifting component. The cold storage box connector includes two connecting rods 1, which pass through several cold storage boxes 14 and connect them into a whole. Limiting sleeves 5 are respectively fitted at both ends of the connecting rods 1, and the several cold storage boxes are located on the rod body between the two limiting sleeves 5. The cold storage box connector is the core structural unit for achieving integrated fixing of multiple cold storage boxes. The connecting rods mechanically connect the dispersed cold storage boxes through pre-set through holes, forming a stable assembly. The limiting sleeves fitted at both ends of the connecting rods precisely limit the position of the cold storage boxes along the axial direction of the connecting rods, effectively preventing displacement or detachment of the cold storage boxes, thereby maintaining the structural stability of the assembly.

[0050] Cold storage boxes are typically sealed containers. Their outer shells are often made of high-strength, low-temperature-resistant, and well-insulated materials, such as engineering plastics or composite materials, to prevent cold loss and withstand the low-temperature environment inside the cold storage. The interior contains a space to hold the cold storage medium, which is generally a phase change material (PCM). Common PCMs include inorganic hydrated salts and organic fatty acids. These PCMs are encapsulated inside the cold storage box. Some cold storage boxes also have special partition structures or flow channels to optimize the phase change process of the cold storage medium and improve cold storage and release efficiency. Furthermore, the surface of the cold storage box usually has through holes for connecting rods to be inserted for connection to the cold storage box fixing components.

[0051] The two ends of the two connecting rods 1 are connected together by a reinforcing rod. The reinforcing rod is a round tube 6. The connecting rod 1 and the reinforcing rod are connected together by a connector 7. The connector 7 includes a straight cylindrical part 701 through which the connecting rod 1 passes and a crimping part 702 for the reinforcing rod to be inserted. The crimping part 702 is composed of two arc-shaped plates with their inner arc surfaces facing each other. One end of the arc-shaped plate is fixed to the outer wall of the straight cylindrical part 701. A clamping channel for the reinforcing rod is formed between the two arc-shaped plates, and this clamping channel is perpendicular to the axial direction of the straight cylindrical part 701. The connector 7 also includes fastening bolts that can fasten the two arc-shaped plates and the reinforcing rod together. By applying a fastening force to the two arc-shaped plates with the fastening bolts, the reinforcing rod and the connector can be tightly fixed, thereby constructing a high-strength frame structure and significantly enhancing the load-bearing capacity and deformation resistance of the connecting parts.

[0052] The lifting assembly plays a crucial role in hoisting the assembled cold storage boxes to the top of the cold storage facility. The lifting assembly consists of a hook 3 and a lifting line 4. The hook 3 is fixed to the top of the cold storage facility 15, and one end of the lifting line 4 is fixedly connected to the hook 3, while the other end is fixedly connected to the connecting rod 1. The lifting line 4 is a closed loop mechanism, with its upper part hanging on the hook 3 and its lower part sleeved on the connecting rod 1.

[0053] There are two ways to install the hooks: First, mark the hook's installation position on the sandwich panel, then use a screwdriver or power tool to screw in the self-tapping screws, penetrating the surface steel plate and polyurethane core material to secure the hook firmly to the panel. Second, first install rivet nuts on the polyurethane sandwich panel, use a specialized rivet gun to fix the rivet nuts to the panel, and then connect the hook to the rivet nuts. Rivet nuts provide more reliable connection strength, preventing the hook from falling off during use.

Limiting sleeves 5 are respectively fitted at both ends of the connecting rods 1, and several cold storage boxes are located on the rod body between the two limiting sleeves 5.

[0056] The two ends of the two connecting rods 1 are connected together by a reinforcing rod. The reinforcing rod is a round tube 6. The connecting rod 1 and the reinforcing rod are connected together by a connector 7. The connector 7 includes a straight cylindrical part 701 through which the connecting rod 1 passes and a crimping part 702 for the reinforcing rod to be inserted. The crimping part 702 is composed of two arc-shaped plates with their inner arc surfaces facing each other. One end of the arc-shaped plate is fixed to the outer wall of the straight cylindrical part 701. A clamping channel for the reinforcing rod is formed between the two arc-shaped plates. The clamping channel is perpendicular to the axial direction of the straight cylindrical part 701.

[0057] The lifting component is a long bolt 2, and the end of the bolt 9 of the long bolt 2 can pass through the connecting rod 1 from bottom to top and be fixed to the top plate 15 of the cold storage.

[0058] <Example 3>

[0059] A cold storage box fixing assembly includes a cold storage box connector and a lifting component. The cold storage box connector includes two connecting rods 1, which are used to pass through several cold storage boxes 14 and connect them into a whole. Limiting sleeves 5 are respectively fitted at both ends of the connecting rods 1, and several cold storage boxes are located on the rod body between the two limiting sleeves 5.

[0060] The two ends of the two connecting rods 1 are connected together by a reinforcing rod. The reinforcing rod is a screw 9, with both ends of the screw 9 passing through the two connecting rods 1, and each end of the screw 9 is screwed with a fastening nut.

[0061] The lifting assembly consists of a hook 3 and a lifting line 4. The hook 3 is fixed to the top plate 15 of the cold storage. One end of the lifting line 4 is fixedly connected to the hook 3, and the other end is fixedly connected to the connecting rod 1. The lifting line 4 is a ring-shaped closed mechanism, with its upper part hanging on the hook 3 and its lower part sleeved on the connecting rod 1 or the screw 9.

[0062] <Example 4>

[0063] A cold storage facility includes shelving, which is the core supporting structure inside the cold storage. The shelving consists of uprights 10 and multiple layers of beams 11, forming a stable three-dimensional frame system. The uprights 10, as the main load-bearing components, are perpendicular to the cold storage floor and reliably fixed to the foundation, providing vertical support for the entire shelving and ensuring its structural stability when bearing goods and cold storage units. The multiple layers of beams 11 are horizontally arranged and vertically connected to the uprights, forming multiple storage planes and providing a supporting foundation for storing goods and installing cold storage units. The spacing between two opposite beams on the same layer is precisely designed according to the dimensions and specifications of the cold storage units and goods.

[0064] Several cold storage units are arranged between two opposing crossbeams 11 on the same floor. Each cold storage unit includes two longitudinal rods and several cold storage boxes 14. The cold storage boxes 14 are installed along the length of the two longitudinal rods, and the two ends of the longitudinal rods are connected to the crossbeams 11 by means of hangers 13.

[0065] The top plate 15 of the cold storage is equipped with several fixing components, and several cold storage boxes 14 are threaded through the cold storage box connectors of the fixing components. The hanging component 13 is an L-shaped plate, the horizontal part of which can be erected on the crossbeam 11, and the vertical part is provided with through holes for the longitudinal rods to pass through.

[0066] The fixed components on the cold storage roof work in conjunction with the cold storage units to further enhance the stability and controllability of the cold storage system. When significant temperature fluctuations occur inside the cold storage, the cold storage units and the cold storage boxes on the fixed components work together to store and release cold energy throughout the cold storage space through the phase change process of the phase change material. Hanging components connect the cold storage units to the shelf beams, while the fixed components are connected to the cold storage roof via a hoisting structure. Both components provide fixation and support to the cold storage boxes from different directions, ensuring the stability of the cold storage boxes during cold storage operation.

[0067] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
