Description

Technical Field

[0001] This invention relates to the field of food storage cold storage technology, and in particular to a food storage cold storage with high space utilization. Background Technology

[0002] Cold storage facilities for food are critical infrastructure in the cold chain supply chain. Their core function is to maintain a stable low-temperature environment below 0°C to inhibit microbial activity, delay the spoilage of perishable foods, and ensure the freshness and safety of meat, seafood, and prepared meals from production and transportation to sales. With the expansion of consumer demand for fresh food and the advancement of large-scale production, the proportion of foods requiring hanging storage, such as meat, is increasing. Cold storage facilities must not only meet basic low-temperature storage requirements but also adapt to scenarios involving high-frequency retrieval and the coexistence of multiple product categories, while simultaneously considering energy consumption control and operational efficiency to support the efficient operation of modern cold chain logistics.

[0003] Existing cold storage facilities for food have significant shortcomings in terms of space utilization and functional adaptation. On the one hand, traditional cold storage facilities mostly adopt "stacked storage" or "fixed-spacing suspended storage": stacked storage easily leads to the deformation of meat due to compression and the bottom layer becoming damp, while fixed-spacing suspended storage has a large amount of ineffective space due to the inability to flexibly adjust the spacing of the poles, and it is difficult to achieve "suspended + stacked" combined storage at the same time, resulting in low space utilization. On the other hand, refrigeration systems are mostly designed with fixed air outlets, which can easily create refrigeration dead zones when the storage position is adjusted, causing local temperature fluctuations in meat. Moreover, personnel need to enter the cold storage to retrieve goods, which not only causes a large loss of cold air and increases energy consumption, but also poses safety risks for low-temperature operations, making it difficult to meet the storage requirements of high efficiency, energy saving, and high space utilization.

[0004] Chinese Patent Publication No. CN207556061U discloses a uniform temperature cold storage for food, comprising a cold storage body including an outer wall, a vacuum insulation layer, a polystyrene insulation layer, and an inner wall. A horizontal uniform temperature plate is fixed inside the cold storage body, dividing it into a gas distribution chamber and a storage chamber. Multiple air vents penetrate the uniform temperature plate. Multiple layers of food placement plates are fixed to the inner wall of the storage chamber. The placement plates have a hollow structure filled with activated carbon adsorption particles, and ventilation holes are provided on their upper surfaces. An inlet pipe and an outlet pipe are connected to the upper and lower ends of the cold storage body, respectively. A refrigeration unit is installed between the inlet and outlet pipes. A gas purification device is installed on the pipe connecting the outlet pipe and the refrigeration unit. A phase change energy storage device is connected to the refrigeration unit's exhaust vent. This patent provides good insulation against the outside environment, uniformly distributes the cold air entering the cold storage body, absorbs moldy gases, and allows for energy storage and reuse, making it low-carbon and environmentally friendly.

[0005] However, the above-mentioned devices have low space utilization, are prone to creating refrigeration dead zones, and are inconvenient for taking food out. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention, through the cooperation of various components, can adjust the distance between the five suspension rods, reducing ineffective gaps between the rods and freeing up areas on both sides of the cold storage for stacking packaged foods, avoiding space waste caused by a single storage method. It can also ensure that the air outlet is always aimed at the suspended meat, ensuring that the cold air is evenly distributed around each piece of meat. At the same time, by using the push-out component, the gathering component, and the moving component, when the meat is pushed out, all the meat on the surface of the five suspension rods is gathered together. Operators do not need to adjust their positions around the stacked items and can directly complete the retrieval or hanging of goods in the centralized area, reducing manual intervention and improving the overall loading and unloading efficiency of the cold storage.

[0020] 2. This invention adjusts the spacing of the suspension rods by adjusting the component, causing the air outlet to move together with the suspension rods. This reduces ineffective gaps between the rods and frees up space on both sides of the cold storage, resulting in high space utilization. It avoids the space waste caused by a single storage method while ensuring that the air outlet is always aimed at the suspended meat, keeping the freshness of all meats consistent. When the suspension rods move the suspended meat outwards as a whole, the gathering component and the moving component work together to gather several hooks, concentrating the scattered hooks in the external operating area of ​​the cold storage body. Operators do not need to move back and forth, especially when there are goods piled on both sides, avoiding entering the interior of the cold storage body during operation, shortening the overall operation time and improving work efficiency.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, as Figure 1 and Figure 2As shown, a space-efficient food storage cold storage includes a cold storage body 1. A sliding groove 11 is provided at the rear end of the cold storage body 1. Two sliding grooves 12 are opened at the top of the inner surface of the cold storage body 1. An adjustment component 2 is provided inside the cold storage body 1. The adjustment component 2 includes five suspension rods 28 and several telescopic frames 282. A blowing component 3 is provided at the lower end of the adjustment component 2. The blowing component 3 includes five guide ports 32. When the spacing of the suspension rods 28 changes, it will synchronously drive the corresponding guide ports 32 to move, preventing some meat from falling out of the cold air coverage area due to the movement of the suspension rods 28, eliminating refrigeration dead zones, and preventing local meat from spoiling due to excessively high temperatures. A push-out component 4 is provided inside the cold storage body 1. Gathering components 5 are symmetrically arranged on both the left and right sides of the adjustment component 2. A moving component 6 is provided inside the cold storage body 1.

[0035] During the operation of this embodiment, the cooperation of various components can adjust the distance between the five suspension rods 28, reducing the ineffective gaps between the rods and freeing up the areas on both sides of the cold storage for stacking packaged foods, avoiding the waste of space caused by a single storage method. It can also ensure that the air outlet 31 is always aimed at the suspended meat, ensuring that the cold air distribution around each piece of meat is uniform. At the same time, by using the push-out component 4, the gathering component 5 and the moving component 6, when the meat is pushed out, all the meat on the surface of the five suspension rods 28 is gathered together. Operators do not need to adjust their positions around the stacked items and can directly complete the picking or hanging of goods in the centralized area, reducing manual intervention and improving the overall loading and unloading efficiency of the cold storage.

[0036] Example 2, as Figure 2-6 The adjustment component 2 also includes an outer shell 21 fixedly connected to the rear end of the cold storage body 1. Limiting rods 22 are fixedly connected to the inner surfaces of the two sliding grooves 12. Sliding seats 23 are slidably connected to the outer surfaces of the two limiting rods 22. Fixed rods 24 are fixedly connected to the inner surfaces of the lower ends of the two sliding seats 23. Five sliding blocks 25 are slidably connected to the outer surfaces of the fixed rods 24. A switch 231 is provided at the front end of the right sliding seat 23. Several hooks 281 are slidably connected to the outer surfaces of the five suspension rods 28. Adjacent hooks 281 in the horizontal direction are connected by a telescopic frame 282, so that the hooks 281 on the surface of the five suspension rods 28 can be adjusted synchronously to adjust the vertical spacing of the meat without hindering the adjustment of the spacing of the five suspension rods 28. Support plates 210 are fixedly connected to the left and right sides of the inner surface of the cold storage body 1, and other food and goods can be stacked on the surface of the support plates 210 on both sides.

[0037] Furthermore, the sliding seat 23 and the limiting rod 22 can support the fixed rod 24 as a whole, so that the five suspension rods 28 can move back and forth stably.

[0038] Each of the five sliding blocks 25 has a slot 251 at its lower end. The rear ends of each of the five sliding blocks 25 are slidably connected to a rotating shaft 26. The rear ends of the five rotating shafts 26 are rotatably connected to a telescopic connecting rod 27. The rear end of the rotating shaft 26 located in the middle position is rotatably connected to the inner surface of the outer shell 21. An electric telescopic rod 29 is fixedly installed on the right side wall of the inner surface of the sliding groove 11. The output end of the electric telescopic rod 29 is rotatably connected to the right rotating shaft 26. When the electric telescopic rod 29 pushes the rightmost rotating shaft 26 to move, it can drive the distance between the five sliding blocks 25 to shorten synchronously. The front ends of each of the five sliding blocks 25 are fixedly connected to the suspension rod 28 on the same side.

[0039] Furthermore, the telescopic link 27 is composed of multiple links, and because the rotating shaft 26 located in the middle position is connected and limited to the outer shell 21, when the rotating shaft 26 at one end is pushed, it will squeeze the entire telescopic link 27 to retract towards the middle in a synchronous manner, thereby causing the distance between the five suspension rods 28 to shrink synchronously, thus freeing up the storage space for the support plates 210 on both sides.

[0040] In the initial stage, the suspension rods 28 are at their maximum spacing. This wide spacing ensures convenient operation during the meat hanging stage and solves the problem of "inconvenient hanging of goods". The narrow spacing after being closed is adapted to the storage needs of the cold storage body 1, reduces the ineffective gaps between the suspension rods 28, and makes room for the support plates 210 on both sides to stack packaged food, realizing a composite storage mode of "suspension + stacking" and improving the overall space utilization of the cold storage.

[0041] Furthermore, after the meat is hung on the hook 281, the electric telescopic rod 29 is activated to push the rotating shaft 26 on the right side to move to the left, thereby causing the entire telescopic connecting rod 27 to converge towards the center, reducing the distance between the five suspension rods 28, thereby reducing the ineffective gaps between the rods and freeing up the area on both sides of the cold storage body 1 for stacking packaged food.

[0042] like Figure 2-4 The blowing assembly 3 includes an air outlet 31 fixedly installed on the bottom wall of the inner surface of the cold storage body 1. Five guide ports 32 are slidably connected to the upper end of the air outlet 31. The five guide ports 32 are located directly below the five sliding blocks 25. Six telescopic plates 33 are provided at the upper end of the air outlet 31. Adjacent guide ports 32 are connected by telescopic plates 33. The left end of the guide port 32 on the left side is connected to the left side wall of the inner surface of the cold storage body 1 by telescopic plates 33. The right end of the guide port 32 on the right side is connected to the right side wall of the inner surface of the cold storage body 1 by telescopic plates 33. The rear end of the upper end of each of the five guide ports 32 is fixedly connected to a connecting seat 34. The upper end of each of the five connecting seats 34 is in contact with the inner surface of the slot 251 on the same side.

[0043] When the cold storage body 1 is operating normally, the cold air generated by the refrigeration system is transported upward from the air vent at the bottom of the cold storage body 1 under the action of the fan. The density of the cold air is greater than that of the ambient air inside the cold storage. After the upward-flowing cold air reaches the top of the cold storage, it will naturally sink downward due to gravity, thus forming a closed-loop airflow of "cold air rising - top sinking". This airflow can cover most of the stored goods in the cold storage. It belongs to the conventional technical field in the prior art, so it will not be described in detail in this solution.

[0044] Furthermore, the connecting seat 34 and the slot 251 are identical in shape and interlock. When the five sliding blocks 25 move, they will simultaneously drive the connecting seat 34 and the guide port 32 on the same side to move together. During the movement, the guide port 32 will squeeze or stretch the telescopic plate 33, change its own position, and guide the cold air to ensure that the guide port 32 is always aligned with the suspended meat, ensuring that the cold air distribution around each piece of meat is uniform, and that there will be no temperature fluctuations in the meat near the stacking areas on both sides, so that the freshness of all the suspended meat remains consistent.

[0045] like Figure 4-5 The component 4 includes a hydraulic device 41 fixedly installed on the rear side wall of the inner surface of the cold storage body 1. The output end of the hydraulic device 41 is fixedly connected to an adjusting seat 42. The rear end of the adjusting seat 42 is provided with a sliding groove 3 43. A sliding rod 44 is fixedly connected to the inner surface of the sliding groove 3 43. Five limiting blocks 45 are slidably connected to the outer surface of the sliding rod 44. The rear ends of the five limiting blocks 45 are all fixedly connected to the suspension rod 28 on the same side.

[0046] Two telescopic rods 46 are fixedly connected to the rear side wall of the inner surface of the cold storage body 1. The front ends of the two telescopic rods 46 are fixedly connected to the adjustment seat 42, which can provide support for the adjustment seat 42 and increase stability. Support seats 47 are fixedly connected to the left and right sides of the inner surface of the cold storage body 1, and the outer surfaces of the two telescopic rods 46 are fixedly connected to the support seats 47 on the same side.

[0047] Furthermore, the telescopic rod 46 is divided into an outer layer and an inner layer. The outer layer of the telescopic rod 46 is fixedly connected to the support base 47, which will not affect the telescopic movement of the inner layer.

[0048] Furthermore, when taking out the meat, the hydraulic device 41 is activated to drive the adjusting seat 42 to move outward as a whole. During the movement, the rotating shaft 26 and the connecting seat 34 are disengaged from the sliding block 25 until the sliding seat 23 moves to the front end of the sliding groove 12. In this state, half of the suspension rod 28 is located outside the cold storage body 1.

[0049] like Figure 7-9The gathering component 5 includes a fixed rod 51 fixedly connected to the left side of the inner surface of the cold storage body 1. The left ends of several hooks 281 located at the far left are all fixedly connected to telescopic frames 52. The left ends of several telescopic frames 52 on the left side are fixedly connected to the inner surface of the cold storage body 1. Several telescopic frames 52 on the left side are all fixedly connected to bending frames 53. Several bending frames 53 on the left side are staggered and slidably connected.

[0050] Furthermore, the telescopic frame 2 52 is divided into an outer layer and an inner layer, and several bending frames 53 are connected to the outer layer of the telescopic frame 2 52, which will not hinder the telescopic movement of the inner layer.

[0051] The left ends of several bending frames 53 on the left are fixedly connected to movable blocks 54. Several movable blocks 54 are slidably connected to the outer surface of the left fixed rod 51. The lower ends of several movable blocks 54 are rotatably connected to telescopic connecting rod 55. An electric telescopic rod 56 is fixedly installed on the left side of the rear side wall of the inner surface of the cold storage body 1. The output end of the left electric telescopic rod 56 is fixedly connected to the movable block 54 on the left and the rearmost side. The electric telescopic rod 56 is electrically connected to switch 231. A sensor is installed inside the electric telescopic rod 56. The sensor is electrically connected to hydraulic device 41.

[0052] Furthermore, the electric telescopic rod 56 is fixedly connected to the movable block 54 located at the rear. When the electric telescopic rod 56 pushes the movable block 54, the thrust is transmitted to the telescopic connecting rod 55, which then synchronously drives the remaining movable blocks 54, causing several movable blocks 54 to slide towards the front end in the same direction. In the initial stage of sliding, the movable block 54 at the front end is quickly blocked by the fixed block and cannot continue to move. However, the telescopic connecting rod 55 can still transmit the thrust to the unobstructed movable blocks 54, allowing them to continue sliding towards the front end. At this time, the telescopic connecting rod 55 gradually contracts and folds according to the position difference of the movable blocks 54 until all the movable blocks 54 are completely in contact. At this time, all the hooks 281 are moved to the outside of the cold storage body 1 and are located in the front half of the suspension rod 28. Among them, the leftmost movable block 54 moves further than the other movable blocks 54 because it starts moving from the initial position and is not obstructed in advance.

[0053] Furthermore, the electric telescopic rod 256, which can be moved by external force when not in operation and can continue to perform electric stroke after being powered on, belongs to existing technology. Its core working principle is that a controllable "clutch / unlocking device" is added to the transmission system. When not powered on, the device is in a disengaged state, completely disconnecting the motor from the internal screw transmission mechanism, thereby releasing the system's self-locking function. At this time, the electric telescopic rod 256 can be stretched or compressed relatively freely by external force. When powered on, the device, usually an electromagnetic clutch or an electronically controlled locking pin, will instantly engage or lock, reconnecting the motor and transmission mechanism, restoring the standard electric mode. The motor drives the subsequent telescopic stroke and provides precise control and holding force. For example, in the event of a fire and power outage, firefighters or emergency systems must be allowed to manually push the window open to ventilate smoke by external force. When power is restored, it can be electrically closed or adjusted through the central control system.

[0054] like Figure 10-11 The movable component 6 includes a movable frame 61, with guide blocks 62 fixedly connected to both the left and right sides of the movable frame 61. Guide seats 63 are fixedly connected to both the left and right sides of the inner surface of the cold storage body 1. The outer surfaces of the two guide blocks 62 are slidably connected to the upper end of the guide seat 63 on the same side. The guide seat 63 is composed of two horizontal plates and one inclined plate.

[0055] The rear end of the adjusting seat 42 is fixedly connected to several fixed posts 64, and the rear end of each of the fixed posts 64 is fixedly connected to a sliding block 67. The front end of the movable frame 61 is fixedly connected to several adjusting blocks 65, and the inner surface of each of the adjusting blocks 65 is fixedly connected to an adjusting rod 66. Each of the sliding blocks 67 is slidably connected to the outer surface of the adjusting rod 66 on the same side. The movable frame 61 is slidably connected to the outer surface of several hooks 281.

[0056] Furthermore, the movable frame 61 is composed of several partitions, each of which corresponds to and is engaged with a horizontal row of hooks 281. When the hydraulic device 41 pushes the adjusting seat 42 to move, the movable frame 61 will synchronously drive the hooks 281 and the suspension rod 28 to move outward together. In this state, the two guide blocks 62 will slide on the horizontal surface of the lower side of the guide seat 63. When the suspension rod 28 is about to move to the outermost position, the guide blocks 62 will move to the inclined plate of the guide seat 63 and be lifted upward under its guiding action. When the suspension rod 28 moves to the outermost position, the movable frame 61 will completely disengage from the hooks 281. When the movable frame 61 rises, it will drive the adjusting block 65 and the sliding block 67 to rise synchronously.

[0057] Furthermore, when the hydraulic device 41 moves the sliding seat 23, the sliding block 25 will first disengage from the rotating shaft 26 and the connecting seat 34 and move outward. During this process, the movable frame 61 synchronously drives several hooks 281 to slide stably on the suspension rod 28. In this state, the distance between the hooks 281 remains unchanged. At the same time, the electric telescopic rod 56 is also in a state of being extended without being opened, moving outward at a constant speed until the sliding seat 23 drives the sliding block 25 to move to the front end of the sliding groove 12. The switch 231 is then activated, causing the hydraulic device 41 to... Stop operation and start electric telescopic rod 2 56. Electric telescopic rod 2 56 pushes the movable block 54 to move forward and squeeze, so that several movable blocks 54 gather at the front end of the fixed rod 2 51. Simultaneously, several horizontal hooks 281 gather at the part of the suspension rod 28 located outside the cold storage body 1, so that the suspended meat is away from the internal structure of the cold storage body 1 and the stacking area on both sides. The meat position is uniform, and the operator can quickly pick up or hang the goods, reducing repeated movement and actions. It also eliminates the need to reach into the narrow space inside the cold storage body 1, avoiding the risk of bumps caused by accidentally touching equipment parts.

[0058] Furthermore, the sensor inside the electric telescopic pole 56, during the extension process of the electric telescopic pole 56, when it passes the preset sensing point, determines the current motion state as "extension" through the built-in program logic of the controller, and thus actively ignores the sensing signal. When it needs to retract, the controller instructs the electric telescopic pole 56 to retract in the opposite direction. When it reaches the sensing point, since the motion direction is "retraction" at this time, the preset triggering condition is met, and the sensor will immediately send a signal to the controller. The controller will execute the "power switching" command the instant it receives the signal: immediately cut off the power supply of the electric telescopic pole 56, and at the same time start the hydraulic device 41 to retract.

[0059] After the operator finishes retrieving or hanging goods, the electric telescopic rod 56 is retracted independently. When the electric telescopic rod 56 touches the sensor inside itself, the electric telescopic rod 56 is de-energized and the hydraulic device 41 is activated simultaneously to begin retraction. At the beginning of the retraction, the hook 281 remains stationary, and the movable frame 61 begins to retract until the two guide blocks 62 move back to the horizontal plate on the lower side of the guide seat 63, so that the movable frame 61 re-attaches to the hooks 281. At this time, the hooks 281 will retract into the interior of the cold storage body 1 along with the retraction.

[0060] In this application, the internal and surrounding moving parts of the cold storage body 1 are all equipped with an active electric heating system, such as electric heating wires laid along the groove or heating plates installed at the expansion joints. The system is managed by temperature sensors and controllers and is automatically activated when the equipment is stationary or the temperature is below the freezing point. It melts the ice crystals formed by moisture condensation through precise heating, thus fundamentally preventing freezing. At the same time, a special low-temperature lubricating grease is used. This lubricant can still maintain excellent fluidity and lubrication effect in environments tens of degrees below zero and has excellent water resistance, which can effectively isolate moisture. In terms of material selection, stainless steel, metals with special coatings, or ultra-high molecular weight polyethylene, which are not easy to stick to ice, are preferred. These are all conventional technical fields in the prior art.

[0061] Therefore, this solution adjusts the spacing of the suspension rods 28 by adjusting component 2, which moves the air outlet 31 and the suspension rods 28 together. This reduces the ineffective gaps between the rods and frees up the areas on both sides of the cold storage, resulting in high space utilization. It avoids the space waste caused by a single storage method and ensures that the air outlet 31 is always aligned with the suspended meat, keeping the freshness of all meat consistent. When the suspension rods 28 move the suspended meat outward as a whole, the gathering component 5 and the moving component 6 work together to gather several hooks 281, concentrating the scattered hooks 281 in the external operating area of ​​the cold storage body 1. Operators do not need to move back and forth, especially when there are goods piled on both sides. This avoids entering the interior of the cold storage body 1 during operation, shortens the overall operation time, and improves work efficiency.

[0062] It should be noted that the specific installation methods, circuit connection methods, and control methods of the switch 231, electric telescopic rod 29, hydraulic device 41, and electric telescopic rod 56 used in this invention are all conventional designs, and will not be described in detail in this invention.
