Description

Technical Field

[0001] This invention relates to the field of refrigerated transport equipment technology, specifically to an intelligent refrigerated transport and transfer device for blood banks. Background Technology

[0002] To ensure the activity and stability of blood samples during storage, specialized blood sample refrigeration storage equipment is usually required. The core function of this equipment is to provide a continuous and stable low-temperature environment for blood samples and to enable orderly management and convenient access to the samples. Currently, most commercially available blood sample refrigeration and storage equipment is primarily box-type, with its interior typically divided into a single refrigeration area. All blood samples are stored together in fixed shelves or drawers within this area. While some equipment attempts to partition the internal space, the partitioning methods are rather crude, failing to design differentiated storage areas for blood samples of different sizes and storage requirements (such as bagged whole blood, bottled plasma, and test tube serum). This not only results in a chaotic internal layout but also leads to significant unused space, generally resulting in low space utilization and failing to meet the needs of medical institutions for efficient storage of large volumes of blood samples. Meanwhile, existing equipment often uses fixed drawer or pull-out shelf designs for its storage components. When blood samples need to be stored, operators must manually pull the entire drawer or shelf out of the equipment to place or retrieve the sample. This method is labor-intensive, makes it impossible to quickly access multiple samples in different locations simultaneously, and results in low efficiency. Furthermore, when the drawer or shelf is fully extended, the internal refrigeration area is exposed to the external environment for a large area and a long time, causing a significant loss of cold air. This not only increases the equipment's cooling energy consumption but also causes temperature fluctuations within the refrigeration area, disrupting the stability of the low-temperature environment and ultimately affecting the quality of stored blood samples. Summary of the Invention

[0003] In order to achieve flexible and reasonable storage and transfer of different blood samples, this application provides an intelligent refrigerated transport and transfer device for blood banks.

[0004] This invention is implemented as follows: A blood bank intelligent refrigerated transport and transfer device includes an equipment base. A transport box is fixedly installed on the upper surface of the equipment base. A partition frame is provided in the transport box. The partition frame is sealed and fixedly connected to the transport box, and the partition frame divides the space in the transport box into a fixed refrigeration area, a variable refrigeration area, and a tool area. Several sets of sliding frames are installed at an angle in the fixed refrigeration area, and a power component is also provided in the fixed refrigeration area to drive the movement of any sliding frame. A storage box is fixedly installed on the sliding frame, and the head of the storage box can extend from the side of the equipment base. A flip-top sealing plate is installed in the variable refrigeration area. The lower end of the flip-top sealing plate is rotatably connected to the transport box, and an electric cylinder is also installed in the transport box to drive the flip-top sealing plate to flip. A refrigeration component for cooling the fixed refrigeration area and the variable refrigeration area is also fixedly installed on the outer end of the equipment base.

[0005] By adopting the above technical solution, the equipment base serves as the main structure. During use, the equipment base is fixedly mounted on a transfer device such as a mobile trolley. A transport box is then fixedly installed on the upper surface of the equipment base, forming a refrigerated space. Dividers within the transport box divide the storage space into different areas: a fixed refrigerated area, a variable refrigerated area, and a tool area. This division of functional areas meets various needs, including blood sample refrigeration and tool storage. The tilted sliding rack and extendable storage box facilitate blood sample access and improve work efficiency. A power unit drives the sliding rack, allowing for accurate movement of the storage box to its designated position. The flip-top sealing plate and electric cylinder allow for flexible adjustment of the variable refrigerated area. When the sealing plate is flipped up, the variable refrigerated area is separated from the fixed refrigerated area, making it suitable for room temperature storage. When the sealing plate is flipped up, the variable and fixed refrigerated areas are connected, allowing the variable refrigerated area to be used for storing large items. The refrigeration system provides a stable low-temperature environment for both fixed and variable refrigeration zones, ensuring the storage quality of blood samples and other items.

[0006] Furthermore, the transport box includes an insulated shell, a vertical middle plate, and side covers. The insulated shell is sealed and fixed to the upper end face of the equipment base. The vertical middle plate is fixedly installed on the inner wall of the tool area. The side covers are configured as two sets, which are sealed and fixed to both sides of the insulated shell and fixedly installed at both ends of the vertical middle plate.

[0007] By adopting the above technical solution, the transport box uses an insulated shell, a vertical middle plate, and side covers. The insulation performance of the insulated shell effectively reduces cold loss and lowers refrigeration energy consumption. After the vertical middle plate is fixedly installed in the transport box, the side covers on both sides can be stably fixed to both ends of the vertical middle plate. The side covers then seal both sides of the insulated shell, ensuring the transport box's airtightness and structural stability, preventing external heat from entering, and further improving the refrigeration effect.

[0008] Furthermore, the partition frame includes a partition mesh panel, a bent baffle, and an arc-shaped partition. The partition mesh panel is installed obliquely in the insulation shell, and the lower end of the partition mesh panel is fixedly connected to the equipment base. One end of the bent baffle is fixedly installed at the head of the partition mesh panel, and the other end of the bent baffle is fixedly connected to the insulation shell. The arc-shaped partition is fixedly installed between the bent baffle and the equipment base.

[0009] By adopting the above technical solution, the combination of partition mesh panels, bent baffles, and arc-shaped partitions in the divider rack rationally divides the space inside the transport box, isolating different areas and avoiding mutual interference. The inclined installation of the partition mesh panels facilitates the layout of the guide rails and also promotes air circulation between the fixed and variable refrigeration zones, ensuring uniformity of refrigeration effect. Furthermore, it prevents damage to other components in the fixed refrigeration zone when retrieving items from the variable refrigeration zone. The bent baffles facilitate better layout and installation of the positioning seats and motor units, while the arc-shaped partitions improve the sealing performance of the flip-over sealing plate during the flipping process.

[0010] Furthermore, the sliding frame includes a positioning inclined rod, a movable seat, and a connecting bracket. The positioning inclined rod is installed obliquely in the insulation shell, and both ends of the positioning inclined rod are fixedly connected to the insulation shell. The movable seat is slidably installed on the positioning inclined rod, and the connecting bracket is slidably installed on the lower end face of the movable seat. A tension spring is also installed between the connecting bracket and the movable seat, and both ends of the tension spring are fixed to the connecting bracket and the movable seat, respectively.

[0011] By adopting the above technical solution, the structural design of the positioning diagonal rod, movable seat, and connecting plate of the sliding frame allows the movable seat to slide flexibly on the positioning diagonal rod. The cooperation between the connecting plate and the power component enables accurate movement of the sliding frame. The tension spring ensures a reliable connection between the connecting plate and the power component, and allows the connecting plate to be lifted when not in use, separating it from the multi-head lifting platform. This prevents the sliding frame from moving synchronously when the multi-head lifting platform moves upward.

[0012] Furthermore, the storage box includes a metal outer shell, a rubber inner shell, and a test tube plate. The lower end face of the metal outer shell is provided with a connecting screw that connects to the movable seat. The lower end of the connecting screw is equipped with a matching locking nut. The rubber inner shell is fitted and fixedly installed on the inner side of the metal outer shell. The test tube plate is evenly installed in the rubber inner shell and is horizontally fixed in the rubber inner shell. The test tube plate has several insertion holes.

[0013] By adopting the above technical solution, the storage box's metal outer shell, rubber inner shell, and test tube plate structure provide excellent protection. The metal outer shell offers good protection, while the rubber inner shell's cushioning properties protect the blood sample tubes from damage. The insertion holes on the test tube plate facilitate the storage and securing of blood sample tubes, ensuring sample stability during transportation. Simultaneously, the connecting screws and locking nuts ensure the storage box is stably fixed to the movable base, allowing for easy opening and closing of the storage box via the movable base during use.

[0014] Furthermore, the power assembly includes a multi-head lifting platform, a transmission belt, and a motor unit that drives the transmission belt to rotate. Several sets of guide rails are fixedly installed on the upper surface of the partition mesh plate. The multi-head lifting platform is slidably installed on the guide rails. Several sets of support strips corresponding one-to-one with the connecting card are integrally formed on the upper surface of the multi-head lifting platform. An electromagnet for attracting the connecting card is also embedded in the upper surface of the multi-head lifting platform. A positioning seat is fixedly installed on the inner side of the insulation shell. A drive wheel shaft is rotatably installed on the positioning seat. A pulley seat and a flip cover seat are fixedly installed on the upper surface of the equipment base. The two ends of the transmission belt are respectively installed on the drive wheel shaft and the pulley seat. A side seat plate connected to the multi-head lifting platform is fixedly installed on the transmission belt. The motor unit is fixedly installed on the positioning seat.

[0015] By adopting the above technical solution, the power assembly is designed as a structure that combines a multi-head lifting platform, a transmission belt, and a motor unit. During use, the motor unit drives the transmission belt to rotate, causing the multi-head lifting platform to slide on the guide rail. Several sets of support strips, each corresponding to a connecting plate, are integrally formed on the upper surface of the multi-head lifting platform. Electromagnets are also embedded in the upper surface of the multi-head lifting platform. In actual use, activating the electromagnet causes the corresponding connecting plate to overcome the tension of the spring and engage with the electromagnet under the influence of attraction. When the connecting plate engages with the electromagnet, the support strips push the connecting plate to move synchronously, realizing the lifting and movement of the sliding frame. This connectable and disconnectable method allows for selective activation of one or more storage boxes at a time via the power assembly, while the unactivated storage box can be arbitrarily selected, making it highly flexible in use. This ensures precise movement of the storage boxes and improves the accuracy and efficiency of blood sample storage and retrieval.

[0016] Furthermore, the flip-top sealing plate includes a heat insulation plate, a connecting seat, and an ear seat connected to the output end of the electric cylinder. The connecting seat is fixedly installed at the lower end of the heat insulation plate and is rotatably installed on the flip-top seat. The ear seat is fixedly installed on the lower end face of the heat insulation plate. An outer ring seal is also fixedly installed on the outer side of the heat insulation plate.

[0017] By adopting the above technical solution, the structure of the insulated plate, connecting seat, and ear seat of the flip-top sealing plate effectively reduces the heat loss of the variable refrigeration compartment due to the heat insulation performance of the insulated plate. The cooperation between the connecting seat and ear seat and the electric cylinder allows the flip-top sealing plate to be flexibly flipped, realizing the adjustment of the variable refrigeration compartment space. The outer ring seal ensures the airtightness between the flip-top sealing plate and the transport box, preventing cold leakage.

[0018] Furthermore, the refrigeration assembly includes a condenser coil assembly, a compressor, an expansion valve, and an evaporator assembly connected in sequence. The condenser coil assembly and the compressor are fixedly mounted on the equipment base. The expansion valve is fixedly mounted on the outer side of the insulation shell. The evaporator assembly is fixedly mounted on the inner side of the top surface of the insulation shell. A dust cover fitted onto the condenser coil assembly is also fixedly mounted on the equipment base. Several sets of auxiliary fans are fixedly mounted on one side of the dust cover.

[0019] By adopting the above technical solution, the condenser coil assembly, compressor, expansion valve, and evaporator assembly of the refrigeration system are connected sequentially to form a complete refrigeration cycle system. The condenser coil assembly dissipates the heat of the refrigerant, the compressor provides the cooling power, the expansion valve regulates the refrigerant flow, and the evaporator assembly absorbs heat, thus achieving cooling for both fixed and variable refrigeration zones. The dust cover and auxiliary fan prevent dust from entering the condenser coil assembly, improving the working efficiency and service life of the refrigeration system.

[0020] Furthermore, the outer surface of the side cover is provided with a first door and a second door that can be flipped open. The first door and the second door correspond to the variable refrigeration area and the tool area, respectively. A movable frame is installed between the two sets of side covers. The movable frame includes a slider seat, a connecting horizontal plate, and a wiping block that cooperates with the evaporation component. A guide groove for mounting the slider seat is opened on the inner surface of the side cover. A linkage plate that is fixedly connected to the movable seat is provided at the lower end of the slider seat. Guide rod assemblies that cooperate with the slider seat are provided at both ends of the connecting horizontal plate. The guide rod assemblies are slidably mounted on the slider seat, and a support spring that supports the guide rod assemblies is also fixedly mounted on the slider seat.

[0021] By adopting the above technical solution, the first and second doors of the side-sealed compartment facilitate the storage and retrieval of items in the variable refrigeration area and tool area. By designing the movable rack as a structure that combines a sliding block, a connecting crossbar, and a wiping block, the wiping block, through its linkage with the sliding rack, can wipe the evaporator assembly, preventing frost buildup and ensuring the stability of the cooling effect.

[0022] Furthermore, the head of the insulation shell is provided with a positioning window for the head of the storage box to extend out, and a placement platform is fixedly installed on the outer side of the insulation shell. The placement platform is located below the positioning window, and a spray pipe is installed above the positioning window. A disinfection box is fixedly installed on the outer side of the insulation shell, and a spray pump for supplying liquid to the spray pipe is installed on the upper end of the disinfection box.

[0023] By adopting the above technical solution, the positioning window and placement platform of the insulated shell facilitate the extension of the storage box and the temporary placement of blood samples. The combination of the spray pipe, disinfection box, and spray pump can disinfect the extended storage box, prevent sample contamination, and improve the safety of the transportation process.

[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) This application meets the storage needs of different items and improves space utilization by rationally dividing the area into a fixed refrigeration zone, a variable refrigeration zone, and a tool zone. The tilting sliding rack and extendable storage box design, along with the precise drive of the power component, make the storage and retrieval of blood samples more convenient and faster, improving work efficiency. The storage box is designed as a long strip structure to ensure that the refrigeration zone has minimal contact with the outside when opened, reducing the rate of cold air loss from the refrigeration zone and further reducing contamination of the refrigeration zone. Furthermore, when the power component drives the storage box, one or more storage boxes can be opened at will, and the opening size can be precisely controlled. The refrigeration component adopts a high-efficiency refrigeration cycle system, which can provide a stable low-temperature environment for the refrigeration area, ensuring the quality of blood samples.

[0025] (2) The design of the variable refrigeration compartment with flip-top panel allows for adjustment of space usage according to actual needs, adapting to different transportation tasks. When large items need refrigeration, the insulation panel can be flipped down using an electric cylinder, making it easy to place the items to be cooled on the insulation panel by opening the first compartment door. When large items do not need refrigeration, the insulation panel can be flipped up using an electric cylinder and attached to the lower end of the partition mesh panel, reducing the space required for refrigeration and thus achieving better energy-saving effects. At the same time, it can also effectively ensure the refrigeration effect of the fixed refrigeration compartment.

[0026] (3) The storage box can be disinfected by the spray disinfection device, which effectively prevents sample contamination and improves the safety of samples and items during the handling process. The movable frame ensures that the sliding block, connecting plate, and wiping block can cooperate with each other during use. Through linkage with the sliding frame, the wiping block can wipe the evaporation component, preventing frost formation and ensuring the stability of the cooling effect. Each time the power unit drives the storage box to open, the evaporation component is wiped once, preventing frost formation and ensuring the stability of the cooling effect. No separate wiping operation is required, making it more energy-efficient and convenient to use. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The intelligent refrigerated transport and transfer device for blood banks includes a base 1. A transport box 2 is fixedly installed on the upper surface of the base 1. A divider 3 is installed inside the transport box 2, and the divider 3 is sealed and fixedly connected to the transport box 2. The divider 3 divides the space inside the transport box 2 into a fixed refrigeration area 201, a variable refrigeration area 202, and a tool area 203. Several sets of sliding frames 8 are installed at an angle in the fixed refrigeration area 201, and a power component 5 is also provided in the fixed refrigeration area 201 to drive the movement of any sliding frame 8. A storage box 4 is fixedly installed on the sliding frame 8, and the head of the storage box 4 can extend from the side of the base 1. The metal outer shell 41 of the storage box 4 is made of medical-grade stainless steel, such as 304 stainless steel, which is corrosion-resistant and easy to clean. The rubber inner shell 42 of the storage box 4 is made of medical-grade silicone rubber, which is soft, wear-resistant, and has good cushioning and shock absorption performance. A flip-top sealing plate 6 is installed in the variable refrigeration zone 202. The lower end of the flip-top sealing plate 6 is rotatably connected to the transport box 2. An electric cylinder 20 is also installed in the transport box 2 to drive the flip-top sealing plate 6 to flip. A refrigeration component 7 for cooling the fixed refrigeration zone 201 and the variable refrigeration zone 202 is also fixedly installed on the outer end of the equipment base 1. The equipment base 1 serves as the main structure. In use, the equipment base 1 needs to be fixedly installed on a transfer device such as a mobile trolley. Then, the transport box 2 is fixedly installed on the upper surface of the equipment base 1, thus forming a refrigerated space. A divider 3 is installed in the transport box 2 to divide the storage space into different areas. By setting up the fixed refrigeration zone 201, the variable refrigeration zone 202, and the tool area 203, different functional areas are divided, meeting various needs such as blood sample refrigeration and tool storage. The tilted sliding frame 8 and the extendable storage box 4 facilitate the storage and retrieval of blood samples and improve work efficiency. The power unit 5 drives the sliding frame 8 to move, facilitating the accurate movement of the storage box 4 to the designated position. The configuration of the flip-top sealing plate 6 and the electric cylinder 20 allows for flexible adjustment of the usage of the variable refrigeration zone 202. When the flip-top sealing plate 6 is flipped up, the variable refrigeration zone 202 is separated from the fixed refrigeration zone 201, making it suitable for room temperature storage. When the flip-top sealing plate 6 is flipped up, the variable refrigeration zone 202 and the fixed refrigeration zone 201 are connected, allowing the variable refrigeration zone 202 to be used for refrigerating and storing large items. The refrigeration unit 7 provides a stable low-temperature environment for both the fixed refrigeration zone 201 and the variable refrigeration zone 202, ensuring the storage quality of blood samples and other items.

[0032] Reference Figure 6 , Figure 8 , Figure 9 and Figure 10The transport box 2 includes an insulated shell 21, a vertical middle plate 22, and side covers 23. The insulated shell 21 is made of high-density polyurethane foam, which has a low thermal conductivity and excellent insulation performance. The insulated shell 21 is sealed and fixed to the upper surface of the equipment base 1. The vertical middle plate 22 is fixedly installed on the inner wall of the tool area 203. The side covers 23 are configured in two sets, which are sealed and fixed to both sides of the insulated shell 21 and fixedly installed at both ends of the vertical middle plate 22. The transport box 2 adopts the structure of insulated shell 21, vertical middle plate 22, and side covers 23. The insulation performance of the insulated shell 21 can effectively reduce cold loss and reduce refrigeration energy consumption. After the vertical middle plate 22 is fixedly installed in the transport box 2, the side covers 23 on both sides can be stably fixed to both ends of the vertical middle plate 22. Then, the side covers 23 can seal both sides of the insulation shell 21, ensuring the airtightness and structural stability of the transport box 2, preventing external heat from entering, and further improving the refrigeration effect.

[0033] Reference Figure 6 and Figure 8 The partition frame 3 includes a partition mesh panel 31, a bent baffle 32, and an arc-shaped partition 33. The partition mesh panel 31 is installed obliquely in the insulation shell 21, and its lower end is fixedly connected to the equipment base 1. One end of the bent baffle 32 is fixedly installed on the head of the partition mesh panel 31, and the other end of the bent baffle 32 is fixedly connected to the insulation shell 21. The arc-shaped partition 33 is fixedly installed between the bent baffle 32 and the equipment base 1. The combination of the partition mesh panel 31, the bent baffle 32, and the arc-shaped partition 33 of the partition frame 3 rationally divides the space inside the transport box 2, isolating different areas from each other and avoiding mutual interference. The inclined installation of the partition mesh panel 31 facilitates the layout of the guide rail 311 and also promotes air circulation between the fixed refrigeration zone 201 and the variable refrigeration zone 202, ensuring uniformity of refrigeration effect. Furthermore, it prevents damage to other components in the fixed refrigeration zone 201 when items need to be placed or removed from the variable refrigeration zone 202. The bent baffle 32 facilitates better layout and installation of the positioning seat 211 and the motor assembly 53, while the arc-shaped partition 33 also improves the sealing performance of the flip-top sealing plate 6 during the flipping process.

[0034] Reference Figure 6 and Figure 7The sliding frame 8 includes a positioning inclined rod 81, a movable seat 82, and a connecting bracket 83. The positioning inclined rod 81 is installed obliquely in the insulation shell 21, and both ends of the positioning inclined rod 81 are fixedly connected to the insulation shell 21. The movable seat 82 is slidably installed on the positioning inclined rod 81, and the connecting bracket 83 is slidably installed on the lower end face of the movable seat 82. A tension spring 831 is also installed between the connecting bracket 83 and the movable seat 82, and both ends of the tension spring 831 are fixed to the connecting bracket 83 and the movable seat 82, respectively. The structural design of the positioning inclined rod 81, the movable seat 82, and the connecting bracket 83 of the sliding frame 8 allows the movable seat 82 to slide flexibly on the positioning inclined rod 81. The cooperation between the connecting bracket 83 and the power component 5 enables the accurate movement of the sliding frame 8. The tension spring 831 ensures a reliable connection between the connecting plate 83 and the power component 5. When not in use, the connecting plate 83 can be lifted by the tension spring 831 to separate the connecting plate 83 from the multi-head lifting platform 51. This prevents the sliding frame 8 from moving synchronously when the multi-head lifting platform 51 moves upward.

[0035] Reference Figure 11 and Figure 12 The storage box 4 includes a metal outer shell 41, a rubber inner shell 42, and a test tube plate 43. The lower end of the metal outer shell 41 is provided with a connecting screw 411 that connects to the movable seat 82. A matching locking nut is installed at the lower end of the connecting screw 411. The rubber inner shell 42 is fitted and fixedly installed on the inner side of the metal outer shell 41. The test tube plate 43 is evenly installed on the rubber inner shell 42 and horizontally fixed within it. Several insertion holes 431 are provided on the test tube plate 43. The structure of the metal outer shell 41, rubber inner shell 42, and test tube plate 43 in the storage box 4 provides good protection. The metal outer shell 41 provides good protection, and the cushioning performance of the rubber inner shell 42 protects the blood sample tubes from damage. The insertion holes 431 on the test tube plate 43 facilitate the storage and fixation of the blood sample tubes, ensuring the stability of the samples during transportation. Meanwhile, the connection screw 411 and the locking nut ensure that the storage box 4 can be stably fixed on the movable seat 82. During use, the movable seat 82 can be used to control the sliding opening and closing of the storage box 4.

[0036] Reference Figure 5 , Figure 6 and Figure 8The power assembly 5 includes a multi-head lifting platform 51, a transmission belt 52, and a motor 53 that drives the transmission belt 52 to rotate. Several sets of guide rails 311 are fixedly installed on the upper end face of the partition mesh plate 31. The multi-head lifting platform 51 is slidably installed on the guide rails 311. Several sets of support strips 511 corresponding one-to-one with the connecting card table 83 are integrally formed on the upper end face of the multi-head lifting platform 51. An electromagnet 512 for attracting the connecting card table 83 is also embedded in the upper end face of the multi-head lifting platform 51. A positioning seat 211 is fixedly installed on the inner side of the heat insulation shell 21. A drive wheel shaft 212 is rotatably installed on the positioning seat 211. A pulley seat 11 and a flip cover seat 12 are fixedly installed on the upper end face of the equipment base 1. The two ends of the transmission belt 52 are respectively installed on the drive wheel shaft 212 and the pulley seat 11. A side seat plate 520 connected to the multi-head lifting platform 51 is fixedly installed on the transmission belt 52. The motor 53 is fixedly installed on the positioning seat 211. By designing the power assembly 5 as a structure that integrates a multi-head lifting platform 51, a transmission belt 52, and a motor unit 53, the motor unit 53 drives the transmission belt 52 to rotate during use, causing the multi-head lifting platform 51 to slide on the guide rail 311. Several sets of support strips 511, each corresponding to a connecting bracket 83, are integrally formed on the upper surface of the multi-head lifting platform 51. An electromagnet 512 is also embedded in the upper surface of the multi-head lifting platform 51. In actual use, activating the electromagnet 512 causes the corresponding connecting bracket 83 to overcome the tension of the tension spring 831 and engage with the electromagnet 512 under the influence of attraction. When the connecting bracket 83 engages with the electromagnet 512, the support strips 511 push the connecting bracket 83 to move synchronously, thus lifting and moving the sliding frame 8. This connectable and disconnectable design allows for selective activation of one or more sets of storage boxes 4 at a time via the power assembly 5, while the set of storage boxes 4 that remains unactivated can be chosen arbitrarily, making it highly flexible in use. This ensures the precise movement of storage box 4, improving the accuracy and efficiency of blood sample retrieval.

[0037] Reference Figure 5 , Figure 6 and Figure 14The refrigeration assembly 7 includes a condenser coil assembly 71, a compressor 72, an expansion valve 73, and an evaporator assembly 74 connected in sequence. The condenser coil assembly 71 and the compressor 72 are fixedly mounted on the equipment base 1. The expansion valve 73 is fixedly mounted on the outer surface of the insulation shell 21. The evaporator assembly 74 is fixedly mounted on the inner top surface of the insulation shell 21. A dust cover 75 is also fixedly mounted on the equipment base 1 and fitted onto the condenser coil assembly 71. Several auxiliary fans 751 are fixedly mounted on one side of the dust cover 75. The sequential connection of the condenser coil assembly 71, compressor 72, expansion valve 73, and evaporator assembly 74 in the refrigeration assembly 7 forms a complete refrigeration cycle system. The condenser coil assembly 71 dissipates the heat of the refrigerant, the compressor 72 provides cooling power, the expansion valve 73 regulates the refrigerant flow, and the evaporator assembly 74 absorbs heat, thus achieving cooling for the fixed refrigeration zone 201 and the variable refrigeration zone 202. The dust cover 75 and auxiliary fans 751 prevent dust from entering the condenser coil assembly 71, improving the working efficiency and service life of the refrigeration assembly 7.

[0038] Its basic refrigeration principle is that the compressor 72 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, which enters the condenser tube group 71. The gas is cooled by the auxiliary fan 751 and becomes a high-pressure liquid. The liquid is depressurized by the expansion valve 73 and becomes a low-temperature and low-pressure mist refrigerant. The mist refrigerant enters the evaporator 74 to absorb heat in the cold storage area and becomes a gas, and the cycle repeats.

[0039] Example 2 Reference Figure 2 , Figure 4 , Figure 5 and Figure 13 The flip-top sealing plate 6 includes an insulation plate 61, a connecting seat 62, and an ear seat 63 connected to the output end of the electric cylinder 20. The connecting seat 62 is fixedly installed at the lower end of the insulation plate 61 and is rotatably mounted on the flip-top seat 12. The ear seat 63 is fixedly installed on the lower end face of the insulation plate 61, and an outer ring seal 611 is also fixedly installed on the outer side of the insulation plate 61. The structure of the insulation plate 61, connecting seat 62, and ear seat 63 of the flip-top sealing plate 6 effectively reduces the loss of cold air in the variable refrigeration zone 202 due to the insulation performance of the insulation plate 61. The cooperation between the connecting seat 62 and ear seat 63 and the electric cylinder 20 allows the flip-top sealing plate 6 to be flexibly flipped, realizing the adjustment of the space in the variable refrigeration zone 202. The outer ring seal 611 ensures the sealing between the flip-top sealing plate 6 and the transport box 2, preventing cold air leakage. In actual use, when large items need to be refrigerated, the insulation plate 61 can be flipped down using the electric cylinder 20, making it convenient to place the items to be cooled on the insulation plate 61 for refrigeration by opening the first box door 232. When large items do not need to be refrigerated, the insulation plate 61 can be flipped up using the electric cylinder 20 and attached to the lower end of the partition mesh plate 31, which can effectively ensure the refrigeration effect of the fixed refrigeration area 201.

[0040] Example 3 Reference Figure 4 , Figure 5 , Figure 9 and Figure 10 The outer side of the side cover 23 is provided with a first door 232 and a second door 233 that can be flipped open. The first door 232 and the second door 233 correspond to the variable refrigeration area 202 and the tool area 203, respectively. A movable frame 24 is installed between the two sets of side covers 23. The movable frame 24 includes a slider seat 241, a connecting horizontal plate 242 and a wiping block 243 that cooperates with the evaporation component 74. A guide groove 231 for mounting the slider seat 241 is opened on the inner side of the side cover 23. A linkage plate 240 that is fixedly connected to the movable seat 82 is provided at the lower end of the slider seat 241. Guide rod assemblies 244 that cooperate with the slider seat 241 are provided at both ends of the connecting horizontal plate 242. The guide rod assemblies 244 are slidably mounted on the slider seat 241, and a support spring 245 that supports the guide rod assemblies 244 is also fixedly installed on the slider seat 241. The first door 232 and the second door 233 of the side cover 23 facilitate the storage and retrieval of items in the variable refrigeration area 202 and the tool area 203. By designing the movable frame 24 as a structure that combines a slider base 241, a connecting cross plate 242, and a wiping block 243, and through linkage with the sliding frame 8, the wiping block 243 can wipe the evaporator assembly 74. This ensures that the evaporator assembly 74 is wiped once each time the power assembly 5 drives the storage box 4 to open, preventing frost buildup on the evaporator assembly 74 and ensuring stable cooling performance. Furthermore, the guide rod assembly 244 and the support spring 245 ensure that the wiping block 243 better fits the evaporator assembly 74, guaranteeing a good wiping effect.

[0041] Example 4 Reference Figure 5 , Figure 6 and Figure 8 The insulated housing 21 has a positioning window 213 at its head for the storage box 4 to extend out. A placement platform 214 is fixedly installed on the outer surface of the insulated housing 21, positioned below the positioning window 213. A spray pipe 215 is installed above the positioning window 213. A sterilization box 216 is fixedly installed on the outer surface of the insulated housing 21, and a spray pump 217 for supplying liquid to the spray pipe 215 is installed on the upper surface of the sterilization box 216. The positioning window 213 and placement platform 214 of the insulated housing 21 facilitate the extension of the storage box 4 and the temporary placement of blood samples. The combination of the spray pipe 215, sterilization box 216, and spray pump 217 can sterilize the inside of the extended storage box 4, preventing sample contamination and improving the safety of the transportation process.

[0042] Working principle: When blood samples need to be stored, the motor unit 53 is activated, driving the transmission belt 52 to rotate and causing the multi-head lifting platform 51 to slide on the guide rail 311. The corresponding electromagnet 512 is activated when the required storage box 4 is opened. After the electromagnet 512 engages with the connecting plate 83, the multi-head lifting platform 51 can lift the sliding frame 8 and the storage box 4 to the designated position. The head of the storage box 4 extends from the positioning window 213, facilitating the operator to insert the blood sample tubes into the insertion holes 431 of the tube plate 43 of the storage box 4. As the head of the storage box 4 extends from the positioning window 213, the spray pump 217 simultaneously starts, supplying liquid to the spray pipe 215, thereby spraying and disinfecting the inside of the storage box 4 through the spray pipe 215, ensuring that it is not contaminated by external sources during the handling process. After placement, the motor unit 53 moves the storage box 4 back into the transport box 2, and the cooling unit 7 is activated to perform a cooling operation on the transport box 2.

[0043] When larger items need to be refrigerated, the flip-top sealing plate 6 of the variable refrigeration zone 202 is controlled by the electric cylinder 20 to flip down, facilitating communication between the variable refrigeration zone 202 and the fixed refrigeration zone 201. This allows operators to place large items on the flip-top sealing plate 6 through the first door 232 for refrigeration. The items can then be transferred and transported using equipment such as a mobile trolley.

[0044] The actual control method is as follows: the PLC controls the motor unit to drive the transmission belt, which in turn moves the multi-head lifting platform. Electromagnets engage or release the connecting clamps, achieving precise movement and positioning of the sliding frame. The PLC precisely controls the extension and retraction stroke of the electric cylinder to ensure smooth flipping of the sealing plate.

[0045] Simultaneously, based on real-time data from temperature sensors, a PID algorithm controls the compressor's start / stop and cooling capacity to maintain the set temperature. The components can be linked; for example, when the storage box extends, the spray pump can be automatically activated.

[0046] This invention provides an intelligent refrigerated transport and transfer device for blood banks, integrating zoned management, automated transportation, intelligent temperature control, aseptic disinfection, and efficient storage and retrieval. It improves operational efficiency, reduces labor intensity, and enhances safety and hygiene levels without sacrificing temperature control stability, while also possessing good scalability and maintainability. Through optimized design and parameter settings of key components, it can achieve stable and reliable long-term operation, demonstrating significant application value and market potential in cold chain logistics scenarios such as blood banks and hospitals.

[0047] Preferred models, materials, and parameter expansion: The motor unit 53 can be equipped with a servo motor, such as Panasonic MSMD042G1U or Siemens 1FL6034-2AF61-0AA0, and a high-precision reducer to achieve precise control of the power components.

[0048] The electric cylinder 20 can be a servo electric cylinder, such as the THKSRG2WS or HIWINEGH series. The stroke can be set according to the requirements of flipping the sealing plate, such as 100-200mm, and the accuracy can reach ±0.01mm, which can achieve smooth and precise flipping action.

[0049] The compressor 72 of the refrigeration assembly 7 can be either a high-efficiency, low-noise Danfoss SC15CL or Copeland CR40KSB. Refrigerant can be R404A or R134a, meeting environmental standards. A temperature sensor can be installed inside the transport box to monitor the internal temperature in real time. The temperature sensor can be a high-precision NTC thermistor or PT100 platinum resistance thermometer, coupled with a PID control algorithm to achieve temperature fluctuations of ±0.1℃. The evaporator assembly 74 uses a finned tube evaporator with a large surface area and high heat exchange efficiency. It is equipped with a controller for operation, using an industrial-grade PLC such as the Siemens S7-1200 series, Mitsubishi FX5 series, or an embedded microcontroller, integrating functions such as temperature control, power control, electric cylinder control, data acquisition, and communication.

[0050] Electromagnet 512 uses a long-life, high-force electromagnetic chuck, such as a circular electromagnetic chuck, with the diameter designed according to the size of the connecting plate. Drive belt 52 uses a wear-resistant, high-strength synchronous belt, such as the HTD series.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
