Description

Technical Field

[0001] This invention relates to the field of cold storage technology, and in particular to a sealing top plate device for an open-top low-temperature cold storage. Background Technology

[0002] In recent years, fully automated cold storage facilities have received increasing attention and favor from the market. The construction of large-scale fully automated cold storage facilities can effectively address the challenges of limited land resources, reduce operational complexity, and facilitate overall sample management and planning. In existing technologies, automated sample storage facilities typically use partitions at the bottom and insulated doors at the top for insulation. This insulation structure is simple, but retrieving sample boxes requires opening the insulated door first, then removing the cryogenic rack, and finally taking out the sample boxes from the rack. To achieve true automation, specialized robotic arms are needed to open and close the insulated doors, requiring separate door designs. Furthermore, the opening and closing of the doors during sample storage and retrieval slows down the process and increases storage time. Summary of the Invention

[0003] To address the above-mentioned shortcomings, the purpose of this invention is to provide a top-opening low-temperature cold storage sealing top plate device, which aims to solve the technical problem in the prior art that the process of storing and retrieving samples still requires opening and closing the door, which affects the speed of sample storage and retrieval and results in a long storage and retrieval time.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A top-opening low-temperature cold storage sealing top plate device includes a bottom frame, a mounting frame, a middle frame, an insulation board, and a top frame arranged sequentially from bottom to top.

[0006] The bottom frame is set inside the inner library;

[0007] The mounting frame is installed on the bottom frame, and the mounting frame has multiple first through holes for the cryogenic rack to pass through.

[0008] The middle frame is installed on the mounting frame. Multiple first cavities are opened on the middle frame. Insulation blocks are installed in the first cavities. The periphery of the insulation blocks is provided with first channels that are adapted to the first through holes.

[0009] The top frame is mounted on the middle frame, and the top frame has multiple second through holes for the cryogenic racks to pass through.

[0010] The insulation board is installed between the top frames of the middle frame, and multiple second cavities are opened on the insulation board, which correspond one-to-one with the first cavity.

[0011] The top of the cryopreservation rack is inserted into the first and second through holes.

[0012] Using the above structure, the insulation blocks and heat insulation panels keep the cold storage warm. The sealing devices of each frozen storage rack are independent of each other, eliminating the need for a uniform top plate. When taking out the sample box, there is no need to use a professional robotic arm to open the insulated door. Simply take out the required frozen storage rack to retrieve the sample box. The sample storage and retrieval speed is fast and the time is short. The insulation does not use a whole structure, but rather multiple separate insulation blocks, which can avoid material shrinkage and improve insulation performance.

[0013] Preferably, the mounting frame includes a square-shaped support frame and a support plate mounted on the support frame. A first through hole is formed on the support plate. The support frame is mounted on the bottom frame, and four side panels are fixed to the four outer sides of the support frame. The four side panels enclose the mounting area of ​​the middle frame, with the outer side of the middle frame abutting the inner side of the side panels. With this structure, the bottom of the middle frame is inserted into the mounting area, allowing for positioning of the middle frame, facilitating its installation, and improving its stability.

[0014] Preferably, the first through hole is square, and an upwardly extending upright plate is provided at the edge of the first through hole. The upright plate can strengthen the first through hole, prevent tearing, and guide the insertion of the cryopreservation rack, facilitating the placement of the cryopreservation rack.

[0015] Preferably, a second, intersecting channel is formed between adjacent uprights and between the uprights and the surrounding panels, with the bottom of the central frame and the insulation block correspondingly inserted into the second channel. This structure improves the tightness of the connection between the central frame, the insulation block, and the mounting frame, further enhancing the insulation performance of the cold storage.

[0016] Preferably, the insulation block includes a first insertion block and a second insertion block vertically inserted into the first insertion block. This structure reduces the processing difficulty of the insulation block, saves materials, reduces production costs, and facilitates the replacement of the insertion blocks.

[0017] Preferably, the top of the first insertion block has a first insertion groove, and the bottom of the second insertion block has a second insertion groove. The first and second insertion blocks are interlocked through the first and second insertion grooves. This structure further reduces the processing difficulty of the insulation block, saves materials, and reduces production costs.

[0018] Preferably, the two ends of the first and second plug-in blocks are respectively attached to the sidewalls of the first cavity. This structure improves the sealing performance of the connection between the insulation block and the central frame, further enhancing the insulation performance of the cold storage.

[0019] Preferably, the top and middle frames are made of bakelite. Using this material for the top and middle frames increases the frame's strength and prevents deformation.

[0020] Preferably, the upper end of the middle frame is mounted to the top frame with screws, and the lower end of the middle frame is mounted to the mounting frame with screws. This structure facilitates the assembly of the top plate assembly.

[0021] Preferably, the insulation board is made of silicone. Using this material, the insulation board can insulate heat, further improving the insulation performance of the cold storage.

[0022] In summary, this invention provides insulation for the cold storage via a top plate device. Each frozen storage rack has an independent sealing device, eliminating the need for a uniform top plate. When retrieving sample boxes, there's no need for a specialized robotic arm to open the insulated door; simply remove the desired frozen storage rack to retrieve the sample box. Sample storage and retrieval are fast and quick. The insulation does not use a monolithic structure but rather multiple separate insulation blocks, preventing material shrinkage and improving insulation performance. It also facilitates the installation of the central frame and enhances its stability. The upright plates reinforce the first through-hole, preventing tearing, and guide the insertion of the frozen storage racks, facilitating placement. Furthermore, it improves the tightness of the connection between the central frame, insulation blocks, and mounting frame, further enhancing the cold storage's insulation performance.

They only represent relative positional relationships and do not represent absolute positional relationships.

[0034] like Figures 1 to 8 As shown, the automated cold storage consists of an outer storage room and an inner storage room 6 located inside the outer storage room. Frozen storage racks 7 are placed inside the inner storage room 6, and sample boxes 70 are placed on the frozen storage racks 7.

[0035] The present invention relates to a top-opening low-temperature cold storage sealing top plate device, comprising, from bottom to top, a bottom frame 1, a mounting frame 2, a middle frame 3, an insulation board 4, and a top frame 5; the bottom frame 1 is disposed inside the inner storage 6; the mounting frame 2 is mounted on the bottom frame, and the mounting frame 2 has multiple first through holes 20 for cryogenic racks 7 to pass through; the middle frame 3 is mounted on the mounting frame 2, and the middle frame 3 has multiple first cavities 30, in which insulation blocks 8 are installed, and the periphery of the insulation blocks 8 is provided with first channels 80 adapted to the first through holes 20; the top frame 5 is mounted on the middle frame 3, and the top frame 5 has multiple second through holes 50 for cryogenic racks 7 to pass through; the insulation board 4 is installed between the top frame 5 and the middle frame 3, and the insulation board 4 has multiple second cavities 40 corresponding one-to-one with the first cavities 30; the top of the cryogenic rack 7 is inserted into the first through holes 20 and the second through holes 50.

[0036] The insulation blocks 8 and the heat insulation panels 4 keep the cold storage warm. The sealing devices of each freezer rack 7 are independent of each other, and there is no need to set up a uniform top plate. When taking out the sample box 70, there is no need to use a professional robotic arm to open the insulated door. Just take out the required freezer rack 7 and the sample box 70 can be taken out. The sample storage and retrieval speed is fast and the time is short. Instead of using an integral structure for insulation, multiple separate insulation blocks 8 are used, which can avoid material shrinkage and improve insulation performance.

[0037] The bottom frame 1 is preferably made of aluminum. It is a square frame made of multiple aluminum profiles 10 connected together. Each aluminum profile 10 has an inverted T-shaped groove 11 on its side. The vertically placed aluminum profiles 10 and the horizontally placed aluminum profiles 10 are fixed by corner plates 14. T-bolts 12 are slidably installed in the T-shaped grooves 11. The horizontal plate 140 of the corner plate 14 is fixed to the horizontally placed aluminum profile 10 by nuts 13 and T-bolts 12. The vertical plate 141 of the corner plate 14 is fixed to the vertically placed aluminum profile 10 by nuts 13 and T-bolts 12. The mounting frame 2 is made of stainless steel and is installed on the bottom frame 1 by screws. The middle frame 3 is made of bakelite or other low-temperature resistant materials. The middle frame 3 is machined and installed on the bottom frame by screws. The middle frame 3 can be made into a square, a sun, or an eye shape. The frame structure is shaped like a grid. Insulation blocks 8 are installed inside the middle frame 3. The material of insulation blocks 8 is EVA or other insulation materials. Preferably, the material of insulation board 4 is rubber. The material of insulation board 4 can also be rubber or other insulation materials. Insulation board 4 is fixed between the middle frame 3 and the top frame 5 with low-temperature resistant adhesive. The material of top frame 5 is bakelite or other low-temperature resistant materials. Top frame 5 is machined to the required size. The bottom frame 1, mounting frame 2, middle frame 3, insulation board 4 and top frame 5 are all square and their edges are aligned. The cross-sections of middle frame 3 and insulation board 4 are the same.

[0038] The top frame 5 and the middle frame 3 are made of bakelite. Using this material for the top frame 5 and the middle frame 3 can increase their strength and prevent deformation.

[0039] The upper end of the middle frame 3 is screwed onto the top frame 5, and the lower end of the middle frame 3 is screwed onto the mounting frame 2, which facilitates the assembly of the top plate device. The insulation board 4 is made of silicone, which can insulate heat and further improve the insulation performance of the cold storage.

[0040] When assembling the top plate device, place the bottom frame 1 on the assembly platform, then place the mounting frame 2 on the bottom frame 1 and fix the mounting frame 2 on the bottom frame 1 with screws. Then place the middle frame 3 on the mounting frame 2 and fix the middle frame 3 and the mounting frame 2 with screws. Then place the insulation block 8 into the first cavity 30 of the middle frame 3, then place the heat dissipation plate on the middle frame 3. Then apply low-temperature resistant adhesive to the middle frame 3 and stick the top frame 5 onto the heat dissipation plate. Then apply low-temperature resistant adhesive to the heat dissipation plate and stick the top frame 5 onto the heat dissipation plate. Connect the middle frame 3 and the top frame 5 with screws. Finally, place the assembled device into the interior of the inner storage 6 and pass the cryopreservation rack 7 through the second through hole 50, the second cavity 40, the first channel 80, the first cavity 30 and the first through hole 20 in sequence. The bottom of the cryopreservation rack 7 reaches the bottom of the inner storage 6, completing the low-temperature storage of the cryopreservation rack 7.

[0041] When retrieving sample boxes 70, an automated mechanism lifts the cryopreservation rack 7 and removes the sample boxes 70 from it. After removal, the automated mechanism then lowers the cryopreservation rack 7 into the inner storage compartment 6. The top plate device of this invention cooperates with the top of the cryopreservation rack 7 to seal the inner storage compartment 6 and keep the sample boxes 70 warm. This invention eliminates the need for an additional door to seal the inner storage compartment 6, reducing the need for opening and closing doors, increasing the speed of sample box retrieval, saving time, and eliminating the need for a dedicated robotic arm for opening and closing the door, thus saving costs.
