Description

Technical Field

[0001] This invention relates to the field of cold storage technology, specifically to a modular cold storage unit and its assembly and construction method. Background Technology

[0002] With the rapid development of global e-commerce, fresh food, and pharmaceutical cold chain industries, the cold chain logistics market continues to expand. Industry data shows that the global cold chain logistics market size exceeded $300 billion in 2025 and is projected to grow at an average annual rate of 8% over the next five years. Cold storage, as the core infrastructure of cold chain logistics, is experiencing explosive growth in demand. However, traditional civil engineering-style cold storage suffers from significant drawbacks such as long construction cycles, poor flexibility, and limited site adaptability, making it difficult to meet rapidly changing market demands. For example, traditional cold storage typically takes 6-12 months from design to completion, and once built, it is difficult to expand or relocate according to business adjustments, leading to resource waste and increased operating costs. Currently, there are some patented cold storage technologies on the market, such as the one described in "A Modular Cold Storage": specifically, a modular cold storage where the first baffle is fixed to the front end of the base plate, and the second baffle is fixed to... At the rear end of the base plate, the upper ends of the first and second baffles are fixed. Side plates are symmetrically arranged on both sides of the base plate, located between the top and bottom plates. Multiple L-shaped plates are symmetrically arranged on both the first and second baffles. The L-shaped plates are bolted to connect the first baffle to the side plate and the second baffle to the side plate, respectively. The upper end of the base plate has multiple bases and vertical rods. The bottom ends of the vertical rods are inserted into the bases, and the vertical rods are threadedly connected to the bases. This structure is a modular structure, which does not occupy much space during transportation, facilitating transport. (See "A Assembleable Cold Storage...") The invention relates to the field of cold storage assembly technology. Specifically, it describes a assembleable cold storage unit and its assembly method. The cold storage unit includes two symmetrically arranged mounting plates, each with several ear plates fixed to its outer edge and a sealing mechanism installed within it. A connecting frame is bolted to the corresponding ear plates and also includes a sealing mechanism. The connecting frame has threaded holes for mates with the bolts. Wall panels are installed between adjacent connecting frames. This invention utilizes mounting plates, connecting frames, and wall panels for assembly to form a cold storage unit. Its assembly and disassembly are convenient, and the sealing mechanism can quickly seal the connection between the connecting frame and the wall panel, thereby ensuring the insulation effect of the cold storage. At the same time, the sealing mechanism on the mounting plate can seal the connection between the mounting plate and the wall panel during the use of the cold storage. The overall airtightness of the cold storage is strong and the insulation effect is good. The above technologies still have certain improvements and enhancements. Therefore, based on the changing needs of cold storage, the applicant proposes a modular cold storage and its assembly and construction method. It adopts modular design and production, and through modular assembly, it can realize the rapid construction and commissioning of cold storage, which is low-cost and meets market demand. Summary of the Invention

Pins are provided at the lower part of the four corners of the cold storage cover plate, and lifting rings are provided at the four corners and the middle of the upper part of the cold storage cover plate. Corresponding pipeline and electrical installation holes are reserved in the cold storage bottom plate, the short side panel, the long side panel, and the cold storage cover plate, and electromechanical pipelines and equipment are provided.

[0005] Furthermore, the modular cold storage unit is equipped with a short side panel and a long side panel. The short side panel has a built-in mounting slot near its side. Mounting plates are provided on the outer sides of the lower two corners of the short and long side panels, and the mounting plates have mounting slots inside.

[0006] Furthermore, the modular cold storage unit is equipped with a cold storage door, and the cold storage door is equipped with a door mounting base, with hexagonal holes at the upper and lower ends of the door mounting base.

[0007] Furthermore, the modular cold storage unit is equipped with a door hinge fixing mechanism. The door hinge fixing mechanism is installed on the short side plate of the cold storage unit by setting two sets of connecting blocks. An adjusting screw and a guide rod are installed between the connecting blocks. A rotating wheel is set through the connecting block at the lower end of the adjusting screw. Two sets of L-shaped mounting blocks are installed on the adjusting screw and the guide rod. A bearing is set on the L-shaped mounting block. A hexagonal rotating shaft is installed in the bearing. A threaded structure is set at the connection between the L-shaped mounting block and the adjusting screw. The adjusting screw has reverse threads from the middle to both ends.

[0008] Furthermore, the modular cold storage is equipped with a fixing mechanism. The lower part of the fixing mechanism is equipped with a fixing block welded to the bottom plate of the cold storage. The upper part of the fixing block is equipped with a rotation limiting block. The rotation limiting block is installed on the fixing block by fixing bolts. The center of the rotation limiting block is equipped with a bolt through a round hole, and the center of the fixing block is equipped with a threaded hole that matches the external thread of the fixing bolt.

[0009] Furthermore, the modular cold storage unit is equipped with a pin, and a limit ring is provided at the lower end of the pin.

[0010] Furthermore, the modular cold storage unit is equipped with a fixed base cylinder, which has a steel cylinder body. Inside the steel cylinder body, there is a magnetic iron movable block. The magnetic iron movable block is connected to the bottom of the steel cylinder body by a spring. An inner conical limiting ring is installed at the opening of the steel cylinder body. The steel cylinder body and the inner conical limiting ring are fixed by four sets of concave hexagonal head bolts. The upper part of the magnetic iron movable block has a conical structure and four sets of steel ball holes. Steel balls are installed in the steel ball holes. The magnetic iron movable block has guide holes and through holes.

[0011] Furthermore, the modular cold storage is equipped with an auxiliary mechanism. The auxiliary mechanism has an auxiliary mechanism fixing seat installed on the inner side of the short side plate of the cold storage. An auxiliary mechanism threaded rod and an auxiliary mechanism guide rod are installed on the auxiliary mechanism fixing seat. An auxiliary mechanism lifting block is installed on the auxiliary mechanism threaded rod and the auxiliary mechanism guide rod. A strong magnet is installed on the auxiliary mechanism lifting block. A rotating wheel is installed at the lower end of the auxiliary mechanism threaded rod through the auxiliary mechanism fixing seat.

[0012] Furthermore, the specific steps of the assembly and construction method for the modular cold storage are as follows:

[0013] Step 1: Use a crane or hoist to lift the cold storage floor plate to the reserved cold storage installation position, and then adjust and fix the cold storage floor plate through the reserved fixing holes on the cold storage floor plate;

[0014] Step 2: Hoist the short side panels of the cold storage on both sides of the cold storage base plate, and then fix them in place using the fixing mechanism. At the same time, seal the gaps with sealant.

[0015] Step 3: After installing the short side panels of the cold storage unit, hoist the long side panels. When hoisting the long side panels, both ends must be accurately inserted into the mounting slots of the short side panels. After hoisting, use the fixing mechanism for initial fixation, then use instruments and equipment for calibration and adjustment. After the short and long side panels are adjusted, use the fixing mechanism to secure and lock them in place.

[0016] Step 4: Hoist the cold storage cover plate. When hoisting the cold storage cover plate, insert the pins at its lower part into the fixed base cylinder, and complete the fixation of the cold storage cover plate through the self-locking of the fixed base cylinder. Sealant is used to deal with the gap positions.

[0017] Step 5: Install the cold storage door. Install and fix the cold storage door through the door shaft fixing mechanism. When installing, rotate the转轮 on the door shaft fixing mechanism, so that the L-shaped installation block moves towards both ends. After hoisting the cold storage door in place, rotate the转轮 in the reverse direction, so that the L-shaped installation block moves inward to clamp and fix the door installation seat on the cold storage door.

[0018] Step 6: Install the mechanical and electrical pipelines and equipment supporting the cold storage, and complete the debugging of the equipment, that is, complete the installation of the cold storage.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] like Figure 1-2The diagram illustrates a modular cold storage unit and its assembly method. It includes a cold storage base plate 1, short side plates 2, long side plates 3, a cover plate 4, a door 5, a door hinge fixing mechanism 6, a fixing mechanism 7, pins 8, a fixing base cylinder 9, auxiliary mechanisms 10, and lifting rings 11. The modular cold storage unit and its assembly method include a rectangular cold storage base plate 1 with pre-drilled fixing holes. The base plate 1 contains a load-bearing steel frame, an insulation layer, and a surface layer. Two sets of fixing mechanisms 7 are installed at the four corners of the base plate 1, welded to it. Short side plates 2 and long side plates 3 are installed around the upper perimeter of the base plate 1. A cold storage door 5 is installed on one of the short side plates 2, secured by the door hinge fixing mechanism 6. The door hinge fixing mechanism 6 is located at the installation point of the cold storage door 5. The cold storage short side panel 2 is located on the outside of the cold storage; a cold storage cover 4 is installed on the upper part of the cold storage short side panel 2 and the cold storage long side panel 3. A fixed base cylinder 9 is set on the upper side of the cold storage short side panel 2, and auxiliary mechanisms 10 are set on both sides of the cold storage short side panel 2. Pins 8 are set on the lower part of the cold storage cover 4 near the four corners. When installing the cold storage cover 4, the pins 8 are inserted into the fixed base cylinder 9 to fix the cold storage cover 4. Lifting rings 11 are set at the four corners and the middle of the upper part of the cold storage cover 4 to lift the cold storage cover 4. The cold storage bottom plate 1, cold storage short side panel 2, cold storage long side panel 3 and cold storage cover 4 are reserved with corresponding pipeline and electrical installation holes, and are equipped with electromechanical pipelines and equipment. The structure and insulation layer design of the cold storage bottom plate 1, cold storage short side panel 2, cold storage long side panel 3, cold storage cover 4 and cold storage door 5 all comply with the cold storage design and construction standards.

[0037] like Figure 7 As shown, the cold storage unit can be assembled with a short side panel 2 and a long side panel 3. The short side panel 2 has a built-in mounting groove 201 near its side, which matches the thickness of the long side panel 3. The two lower corners of the short side panel 2 and the long side panel 3 are provided with mounting plates 202, which have grooves 203 inside. The mounting plates 202 are prefabricated on the short side panel 2 and the long side panel 3 by welding.

[0038] like Figure 8 , Figure 9As shown, the cold storage door 5 of the assembled cold storage unit is equipped with a door mounting base 501. The door mounting base 501 has hexagonal holes 502 at its upper and lower ends. A door hinge fixing mechanism 6 is installed on the short side plate 2 of the cold storage unit. The door hinge fixing mechanism 6 is installed on the short side plate 2 of the cold storage unit via two sets of connecting blocks 601. The connecting blocks 601 are welded and fixed to the short side plate 1 of the cold storage unit. An adjusting screw 602 and a guide rod 603 are installed between the connecting blocks 601. A rotating wheel 604 is installed at the lower end of the adjusting screw 602 through the connecting block 601. Two sets of L-shaped mounting blocks 605 are installed on the adjusting screw 602 and the guide rod 603. A bearing 606 is installed on the L-shaped mounting block 605. A hexagonal rotating shaft 607 is installed inside the bearing 606. A threaded structure is provided at the connection between the mounting block 605 and the adjusting screw 602. The adjusting screw 602 shown has reverse threads from the middle to both ends. When the rotating wheel 604 is rotated forward, the L-shaped mounting block 605 can be moved to both ends. When the rotating wheel 604 is rotated in reverse, the L-shaped mounting block 605 can be moved towards the center. When installing the cold storage door, by rotating the rotating wheel 604 in the forward direction, the L-shaped mounting block 605 is separated to a sufficient distance to install the cold storage door 5. Then, the cold storage door 5 is hoisted to the installation position. The hexagonal rotating shaft 607 is inserted into the hexagonal hole 502. Then, the rotating wheel 604 is rotated in reverse to make the L-shaped mounting block 605 close and tighten the door, thereby realizing the installation and fixation of the cold storage door 5. The rotation of the cold storage door 5 shown is achieved by the rotation of the bearing 606 connected to the hexagonal rotating shaft 607.

[0039] like Figure 6 As shown, the modular cold storage unit is equipped with a fixing mechanism 7. The fixing mechanism 7 has a fixing block 701 at its lower part, which is welded to the cold storage base plate 1. The size of the fixing block 701 matches the size of the slots 203 in the mounting plates 202 located at the bottom of the short side plate 2 and the long side plate 3 of the cold storage unit. A rotation limiting block 702 is located at the upper part of the fixing block 701, and is mounted on the fixing block 701 by fixing bolts 703. A bolt passes through a circular hole at the center of the rotation limiting block 702. The fixing block 701 has a threaded hole at its center that matches the external thread of the fixing bolt 703. When installing and fixing the short side plate 2 and the long side plate 3 of the cold storage, rotate the rotating limiting block 702 to be flush with the fixing block 701. Then, insert the slot 203 of the mounting plate 202 at the bottom of the short side plate 2 and the long side plate 3 of the cold storage into the outside of the fixing block 701. Then, rotate the rotating limiting block 702 so that it forms a cross structure with the fixing block 701. Finally, tighten the fixing bolt 703 to fix the short side plate 2 and the long side plate 3 of the cold storage.

[0040] like Figures 3-5As shown, the modular cold storage unit is equipped with pins 8, and a limiting ring 801 is provided at the lower end of the pins 8. A fixed base cylinder 9 is provided at both ends of the top of the short side panel 2 of the cold storage unit. The fixed base cylinder 9 has a steel cylinder body 902, which is welded to the main body of the short side panel 2 during installation. A magnetic iron movable block 904 is provided inside the steel cylinder body 902, and the magnetic iron movable block 904 is connected to the bottom of the steel cylinder body 902 by a spring 903. An inner conical limiting ring 908 is installed at the opening of the steel cylinder body 902, and the steel cylinder body 902 and the inner conical limiting ring 908 are fixed by four sets of concave hexagonal head bolts 909. The upper part of the magnetic iron movable block 904 has a conical structure and four sets of steel ball holes 905, and steel balls 901 are installed in the steel ball holes 905. The magnetic iron movable block 904 shown is provided with a guide hole 906 and a through hole 907. When installing and fixing the cold storage cover plate 4, the pin 8 is aligned with the guide hole 906 and inserted. The magnetic iron movable block 904 moves downward under the action of the pin 8. At this time, the top of the pin 8 contacts the steel ball 901 and pushes the magnetic iron movable block 904 installed on the steel ball 901 to move downward. When the magnetic iron movable block 904 reaches a certain distance, the steel ball 901 moves outward due to the large external space. At this time, the steel ball at the front end of the pin 8 loses its force and the pin continues to move downward to the position of the through hole 907. At this time, the magnetic iron movable block 904 moves upward under the force of the spring 903. During the movement, the steel ball is subjected to the action of the upper inner conical limiting ring 908, so that part of the steel ball is stuck in the limiting ring 801. At this time, the fixed base cylinder 9 completes the limiting and fixing of the pin 8.

[0041] like Figure 10 As shown, the modular cold storage unit is equipped with an auxiliary mechanism 10. The auxiliary mechanism 10 has an auxiliary mechanism mounting base 1001 installed on the inner side of the short side panel 2 of the cold storage unit. An auxiliary mechanism threaded rod 1002 and an auxiliary mechanism guide rod 1003 are mounted on the auxiliary mechanism mounting base 1001. An auxiliary mechanism lifting block 1005 is mounted on the auxiliary mechanism threaded rod 1002 and the auxiliary mechanism guide rod 1003. A strong magnet 1006 is mounted on the auxiliary mechanism lifting block 1005. A rotating wheel 1004 is installed at the lower end of the auxiliary mechanism threaded rod 1002, which passes through the auxiliary mechanism mounting base 1001. The auxiliary mechanism 10 is mainly for disassembly / reassembly. When the cold storage cover 4 needs to be removed, the rotating wheel 1004 rotates, which in turn drives the threaded rod 1002 of the auxiliary mechanism to rotate, and at the same time drives the lifting block 1005 of the auxiliary mechanism to move upward. At the same time, the strong magnet 1006 also moves upward. When it moves to a certain position, the strong magnet magnetically attracts the magnetic iron movable block 904 of the fixed base cylinder 9, causing the magnetic iron movable block 904 to compress the spring 903 and move downward. At this time, the steel ball 901 on the top magnetic iron movable block 904 can move outward easily because of the large external space. At this time, the steel ball 901 no longer limits the limit ring 801, making it easy to pull out the pin 8.

[0042] 1. A prefabricable cold storage and its prefabrication construction method as described in claim 1, wherein the specific steps of the prefabrication construction method of the prefabricable cold storage are as follows:

[0043] Step 1: Lift the cold storage floor 1 to the reserved cold storage installation position by a crane or hoist, and then adjust and fix the cold storage floor 1 through the reserved fixing holes on the cold storage floor 1; a support steel skeleton heat insulation layer and a protective layer are provided inside the cold storage floor 1, which has overall supportability and can be installed in various scenarios such as ordinary ground, ships, vehicles, outdoors, and indoors.

[0044] Step 2: Lift the short side panels 2 of the cold storage on both sides of the cold storage floor 1, and then preliminarily fix them through the fixing mechanism 7. At the same time, sealant is used to treat the gaps.

[0045] Step 3: After installing the short side panels 2 of the cold storage, then lift the long side panels 3 of the cold storage. When lifting the long side panels 3 of the cold storage, both ends need to be accurately inserted into the installation slots 201 of the short side panels 2 of the cold storage. After the lifting is completed, preliminarily fix them through the fixing mechanism 7, and then calibrate and adjust them through instrument equipment. After the short side panels 2 and the long side panels 3 of the cold storage are adjusted, fix and lock them through the fixing mechanism 7; sealant installation treatment is involved for the gaps.

[0046] Step 4: Lift the cold storage cover plate 4. When lifting the cold storage cover plate 4, fix the cold storage cover plate 4 by inserting the pins 8 at its lower part into the fixed base cylinders 9 and locking by the self-locking of the fixed base cylinders 9. Sealant treatment is involved for the gap positions.

[0047] Step 5: Install the cold storage door 5, and fix the cold storage door through the door shaft fixing mechanism 6. When installing, rotate the转轮 604 on the door shaft fixing mechanism 6, so that the L-shaped installation block 605 moves towards both ends. After lifting the cold storage door 5 in place, rotate the转轮 604 in the reverse direction, so that the L-shaped installation block 605 moves inwards to clamp and fix the door installation seat 501 on the cold storage door 5.

[0048] Step 6: Install the mechanical and electrical pipelines and equipment supporting the cold storage, and complete the debugging of the equipment, that is, complete the installation of the cold storage.

[0049] As described above, it is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in any other form. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope protected by the present invention.
