Description

Technical Field

[0001] The present invention relates to the technical field of mobile cold storages, and more specifically, to an energy-saving mobile cold storage. Background Art

[0002] In the cold chain logistics industry, as an important storage device, mobile cold storages are widely used for the refrigeration and preservation of various goods.

[0003] In practical applications, most mobile cold storages face the problems of low space utilization rate and energy waste. When there are fewer goods in the cold storage, a large amount of space is left idle, which not only reduces the storage efficiency of the cold storage, but also, with the refrigeration space unchanged, more cold air needs to be converted to fill the entire space in order to maintain the low-temperature environment of the whole cold storage. Therefore, many manufacturers have successively launched movable folding partition walls.

[0004] Currently, although the cold storage partition wall products on the market have solved the problems of low space utilization rate and energy waste of mobile cold storages to a certain extent, they generally face a common problem: there are relatively large gaps between the partition wall and the top surface, bottom surface or side surface of the cold storage. The original intention of these gaps is to adjust the deformation or turning of the partition to adapt to different goods storage requirements. However, these gaps have become the main channels for cold air leakage. Even when the cold storage is divided into two independent spaces, a large amount of cold air will still overflow from these gaps to the space that does not require cooling, resulting in a large amount of energy waste and a reduction in the refrigeration effect.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an energy-saving mobile cold storage that can improve the space utilization rate of the cold storage while effectively preventing cold air leakage to reduce energy consumption. Summary of the Invention

[0006] The purpose of the present invention is to provide an energy-saving mobile cold storage to solve the above problems.

[0007] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: An energy-saving mobile cold storage includes a cold storage. A power supply is arranged on the left side of the cold storage, and a cooling unit is stacked above it. A storage bin is arranged inside the cold storage, and the cooling unit is used to supply cold to the storage bin. A driving mechanism, a cold air isolation mechanism and a cold storage integrated management system are arranged inside the cold storage; The driving mechanism includes a pair of laterally inner sliding grooves and laterally outer sliding grooves that are symmetrically arranged left and right at the inner end of the cold storage and communicate with the storage bin. A lead screw is provided at the geometric center of the laterally inner sliding groove. A slider is provided at the outer end of the lead screw. One end of a pair of the sliders close to each other is fixedly connected with a driven block. A grating inductor is provided at one end of a pair of the driven blocks close to each other. A motor is provided at the geometric center of the driven block. A partition that fits the outer contour thereof is provided at the outer end of the driven block, and the output end of the motor is fixedly connected with the partition. An assembly cavity is further opened at the inner end of the driven block. A connecting shaft is rotatably connected to the inner end of the assembly cavity, and the other end of the connecting shaft is fixedly connected with the partition. The cold air isolation mechanism includes a pair of longitudinally sliding grooves, a placement groove, and a limiting sliding groove that are symmetrically arranged up and down on the partition. The longitudinally sliding grooves communicate with the placement groove and the limiting sliding groove respectively. An active partition is slidably connected in the longitudinally sliding groove. A fixed electromagnet is fixedly connected to the inner bottom end of the placement groove. An active electromagnet is fixedly connected to one end of the active partition close to the fixed electromagnet. A limiting block is fixedly connected to one end of the active partition close to the limiting sliding groove, and the limiting block is slidably connected with the limiting sliding groove.

[0008] As a further improvement of the present invention, the cold storage comprehensive management system includes: Power supply module: including a power supply to provide power supply for the power equipment involved in the whole system; Control module: responsible for receiving signals from the detection module and sending instructions to other modules according to preset logics and algorithms to realize the coordinated operation of the whole system; Detection module: including a grating inductor and a feedback unit, emitting signals to detect whether there are goods stacked between the two, thereby detecting the placement position of the goods in the cold storage and feeding back the detection result to the control module, so that the control module controls the driving module and the isolation module to perform corresponding actions according to the signal result; Motion module: including a lead screw, a slider, and a motor, driving the driven block and the partition to move back and forth along the laterally outer sliding groove through the slider. At the same time, based on the signal result received by the control module from the detection module, controlling the rotation and fitting of the partition through the motor to realize the dynamic separation of the storage bin; Isolation module: including a fixed electromagnet and an active electromagnet, used to drive the isolation module to start the electromagnet program immediately after the partition moves to the specified position, so that a magnetic repulsion force is generated between the fixed electromagnet and the active electromagnet, and the active electromagnet drives the active partition to move synchronously to fill the gaps between the partition and the inner top end and the inner bottom end of the storage bin; Cooling supply module: including a cooling supply unit to provide a refrigeration function for the cold storage and keep the temperature in the storage bin constant during the transportation of goods by the mobile cold storage.

[0009] As a further improvement of the present invention, a plurality of spherical grooves are formed at one end of the connecting shaft located in the assembly cavity, and ball bearings are arranged in the spherical grooves.

[0010] As a further improvement of the present invention, the motor moves in an alternating forward and reverse direction by 90°, so that the partition performs a corresponding rotational movement, realizing precise movement and positioning of the partition in the storage bin.

[0011] As a further improvement of the present invention, the partition only performs a linear sliding or rotational movement along a preset transverse outer sliding groove. When performing a linear sliding, the partition is completely located within the transverse outer sliding groove. After performing a rotational movement, a pair of the partitions are in a fitting state.

[0012] As a further improvement of the present invention, sealing strips are fixedly connected to both the left and right ends of a pair of the partitions, and a sealing strip is also fixedly connected to the end of the movable partition away from the fixed electromagnet.

[0013] As a further improvement of the present invention, the movable partition only slides up and down along a preset longitudinal sliding groove. When a pair of limiting blocks move towards the mutually remote ends, the upper and lower movable partitions respectively fit with the inner top end and the inner bottom end of the storage bin.

[0014] As a further improvement of the present invention, the limiting sliding groove is a "T"-shaped sliding groove shorter than the height of the longitudinal sliding groove, and the shape of the limiting block matches it.

[0015] As a further improvement of the present invention, a pair of elastic connecting pieces are fixedly connected between the fixed electromagnet and the movable electromagnet, and the elastic connecting pieces are made of elastic cord bodies.

[0016] As a further improvement of the present invention, lightweight heat insulation materials are filled inside both the partition 7 and the movable partition 9.

[0017] Compared with the prior art, the advantages of the present invention are as follows: This solution can automatically adjust the partition layout in the cold storage, and divide the interior of the cold storage into two spaces according to the actual size and placement specifications of the goods. At the same time, it can ensure the tight fit between the partition and the movable partition and each surface of the storage bin, thereby greatly reducing the leakage of cold air from these gaps. This not only helps to maintain the ideal refrigeration environment in each separated space, but also significantly reduces the energy consumption of the cooling unit.

[0018] Although this solution focuses on reducing the problem of cold air leakage between the two spaces, it does not sacrifice the flexibility and applicability of the partition, and can still quickly adjust the layout according to actual needs to adapt to the storage requirements of different scales and types of goods.

[0019] This solution helps to promote the development of green and sustainable cold chain logistics, which meets the current global urgent needs for energy conservation, emission reduction and environmental protection, and also helps to enhance the competitiveness of enterprises in the cold chain logistics industry.

Detailed Embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0023] Please refer to Figure 1, An energy-saving mobile cold storage, including a cold storage 1, a power supply is arranged on the left side of the cold storage 1, and a cooling unit 2 is stacked above it. A storage bin 101 is arranged in the cold storage 1, and the storage bin 101 is cooled by the cooling unit 2. The cooling unit 2 is arranged on the side far from the door of the cold storage 1. A driving mechanism, a cold air isolation mechanism and a cold storage integrated management system are arranged in the cold storage 1.

[0024] Please refer to Figures 1-4 and Figures 6-7 , The driving mechanism includes a pair of horizontally inner sliding grooves 102 and horizontally outer sliding grooves 103 that are symmetrically arranged at the inner ends of the cold storage 1 and communicate with the storage bin 101. A lead screw 3 is arranged at the geometric center of the horizontally inner sliding groove 102. A slider 4 is arranged at the outer end of the lead screw 3. The horizontally inner sliding groove 102 is a square groove. The shape and size of the slider 4 match those of the horizontally inner sliding groove 102. One end of a pair of sliders 4 close to each other is fixedly connected with a driven block 5. The driven block 5 serves to connect the slider 4 and the partition 7. The end of the driven block 5 away from the slider 4 is semicircular. A pair of grating sensors are arranged at one end of a pair of driven blocks 5 close to each other. The placement position of the outermost goods in the storage bin 101 is captured by this pair of grating sensors. A motor 6 is arranged at the geometric center of the driven block 5. A partition 7 that fits its outer contour is arranged at the outer end of the driven block 5. The output end of the motor 6 is fixedly connected with the partition 7, so that the partition 7 can rotate along the outer contour of the driven block 5. An assembly cavity 501 is also opened at the inner end of the driven block 5. A connecting shaft 8 is rotatably connected to the inner end of the assembly cavity 501. The other end of the connecting shaft 8 is fixedly connected with the partition 7. A plurality of spherical grooves are opened at one end of the connecting shaft 8 located in the assembly cavity 501. Ball bearings 801 are arranged in the spherical grooves to reduce the friction between the connecting shaft 8 and the assembly cavity 501, making the rotation of the partition 7 smoother. The movement mode of the motor 6 is to alternately rotate forward and backward by 90°, so that the partition 7 performs corresponding rotational movements, realizing the precise movement and positioning of the partition 7 in the storage bin 101. The partition 7 only performs linear sliding or rotational movements along the preset horizontally outer sliding groove 103. When performing linear sliding, the partition 7 is completely located in the horizontally outer sliding groove 103, and the horizontally outer sliding groove 103 is not parallel to the top and bottom of the storage bin 101. Therefore, this setting method can reduce the contact generated between the goods loading and the partition 7, thereby reducing the interference with the feeding of the goods and indirectly improving the service life of the partition 7. After performing rotational movements, a pair of partitions 7 are in a fitting state. Sealing strips are fixedly connected to the left and right ends of a pair of partitions 7. The area where goods are stored in the storage bin 101 and the idle area are initially isolated by a pair of partitions 7 in a fitting state.

[0025] It should be noted that when loading goods, the slider 4 in this solution is located at the end of the transverse inner chute 102 far from the warehouse door, and the partition 7 is parallel to the transverse outer chute 103. Only after the goods are loaded will it move towards the end close to the warehouse door so that the grating sensor can accurately sense the placement position of the outermost goods in the storage bin 101.

[0026] Please refer to Figure 1 、 Figure 3 and Figures 5-7 , the cold air isolation mechanism, including a pair of longitudinally symmetrically arranged longitudinal chutes 701, placement grooves 702 and limit chutes 703 on the partition 7. The longitudinal chutes 701 are respectively connected to the placement grooves 702 and the limit chutes 703. A movable partition 9 is slidably connected in the longitudinal chute 701. The movable partition 9 only slides up and down along the preset longitudinal chute 701. When a pair of limit blocks 901 move towards the ends away from each other, the upper and lower movable partitions 9 are respectively attached to the inner top end and the inner bottom end of the storage bin 101. A sealing strip is fixedly connected to the end of the movable partition 9 away from the fixed electromagnet 10 to improve the sealing performance between the movable partition 9 and the inner top end and the inner bottom end of the storage bin 101. In this way, the movable partition 9 fills the part with gaps between the partition 7 and the inner top end and the inner bottom end of the storage bin 101, so that the side of the storage bin 101 loaded with goods and the other side are completely separated into two independent spaces, thereby greatly reducing the cold air leakage. Reducing the cold air leakage means that both of the two separated spaces can maintain a more stable temperature environment, thus improving the overall refrigeration effect, which is particularly important for goods that need to be refrigerated for a long time and helps to extend their freshness period and reduce losses.

[0027] Please refer to Figure 3 and Figure 5, a fixed electromagnet 10 is fixedly connected to the inner bottom end of the storage slot 702, and a movable electromagnet 11 is fixedly connected to one end of the movable partition 9 close to the fixed electromagnet 10. The movable partition 9 is driven to perform corresponding displacement through the fixed electromagnet 10 and the movable electromagnet 11. When these two electromagnets are energized, a magnetic repulsive force will be generated between them, causing the movable electromagnet 11 to drive the movable partition 9 to move towards the end away from the fixed electromagnet 10, so as to ensure that the movable partition 9 is always in contact with the inner top end and the inner bottom end of the storage bin 101 during transportation. A pair of elastic connectors 12 are fixedly connected between the fixed electromagnet 10 and the movable electromagnet 11. The elastic connectors 12 are made of elastic rope bodies, and other elastic components such as springs can also be used. The partition 7 and the movable partition 9 are both filled with lightweight heat-insulating materials, such as conventional polystyrene foam plastics, and polyurethane foam plastics with better heat preservation and sealing performance can also be selected according to user needs. The elastic connectors 12 are used to ensure that when the fixed electromagnet 10 and the movable electromagnet 11 are not activated, sufficient pulling force is provided for the lighter movable partition 9 located below, to prevent the sealing strip at the lower end of the movable partition 9 from rubbing against the bottom of the horizontal inner chute 102 during the sliding movement of the movable partition 9 along with the partition 7, resulting in damage to the sealing strip and affecting the overall heat-insulating performance of the equipment. A limiting block 901 is fixedly connected to one end of the movable partition 9 close to the limiting chute 703, and the limiting block 901 is slidably connected to the limiting chute 703. The limiting chute 703 is set as a "T"-shaped chute shorter than the height of the longitudinal chute 701, and the shape of the limiting block 901 matches it. The movement trajectory and movement stroke of the movable partition 9 are limited through the limiting chute 703 and the limiting block 901, preventing the movable partition 9 from colliding and squeezing with the inner top end or the inner bottom end of the storage bin 101 due to an excessive movement stroke, thereby improving the service life of the equipment.

[0028] The cold storage comprehensive management system includes: Power supply module: including a power supply to provide power supply for the electrical equipment involved in the entire system; Control module: responsible for receiving signals from the detection module and sending instructions to other modules according to preset logics and algorithms to achieve the coordinated operation of the entire system; Detection module: including a grating sensor and a feedback unit, emitting signals to detect whether there are goods stacked between them, thereby detecting the placement position of goods in the cold storage and feeding back the detection results to the control module. During the movement of the driven block 5 equipped with the grating sensor from the end far away from the warehouse door towards the end close to the warehouse door along with the slider 4, when the grating sensor does not detect goods, a signal is sent to the control module through the feedback unit, and the control module controls the drive module and the isolation module to perform corresponding actions according to the signal result; Movement module: It includes a lead screw 3, a slider 4, and a motor 6. After the goods are loaded, the control module first controls the slider 4 located at the innermost end of the transverse inner chute 102 to drive the driven block 5 and the partition 7 to move towards the end close to the warehouse door. During this process, the detection module discriminates whether the goods are detected and sends a signal to the control module. Then, based on the signal result received by the control module, the rotation and fitting of the partition 7 are controlled by the motor 6 in the movement module to achieve the dynamic separation of the storage bin 101. Isolation module: It includes a fixed electromagnet 10 and a movable electromagnet 11, which are used to, after the partition 7 moves to the specified position, immediately drive the isolation module to start the electromagnet program by the control module, so that a magnetic repulsion force is generated between the fixed electromagnet 10 and the movable electromagnet 11, causing the movable electromagnet 11 to drive the movable partition 9 to move synchronously and fill the gaps between the partition 7 and the inner top and inner bottom of the storage bin 101. Cooling module: It includes a cooling unit 2, which provides a refrigeration function for the cold storage and keeps the temperature in the storage bin 101 constant during the transportation of goods by the mobile cold storage.

[0029] The present invention can automatically adjust the separation layout in the cold storage, and divide the interior of the cold storage 1 into two spaces according to the actual size and placement specifications of the goods. At the same time, it can ensure the tight fit between the partition 7 and the movable partition 9 and each surface of the storage bin 101, thus greatly reducing the leakage of cold air from these gaps. This not only helps to maintain the ideal refrigeration environment in each separated space, but also significantly reduces the energy consumption of the cooling unit 2. Although the present invention focuses on reducing the problem of cold air leakage between the two spaces, it does not sacrifice the flexibility and applicability of the partition 7. At the same time, the present invention helps to promote the development of green and sustainable cold chain logistics, which meets the current global urgent needs for energy conservation, emission reduction and environmental protection, and also helps to enhance the competitiveness of enterprises in the cold chain logistics industry.
