Description
Technical Field
[0001] This invention relates to the field of cold storage technology, specifically an energy-saving partitioned cold storage. Background Technology
[0002] Energy-saving partitioned cold storage is a type of cold storage facility that reduces energy consumption through optimized design and material selection. Its core feature is the use of efficient partition technology to reduce cold loss while maintaining a stable temperature inside the storage room.
[0003] Patent publication number CN216432213U relates to an environmentally friendly and energy-saving partitioned cold storage, including a cold storage body with a refrigeration compartment inside. A door is located on one side of the cold storage body, and a handle is fixedly connected to the outer surface of the door. A mounting frame is fixedly connected to one end of the refrigeration compartment near the door, and a mounting plate is fixedly connected to one side of the mounting frame. The mounting frame is fixedly connected to the inner wall of the refrigeration compartment via the mounting plate. A connecting crossbar is provided on the adjacent side of two mounting frames. This environmentally friendly and energy-saving partitioned cold storage has a simple structure and is easy to install. By installing a heat insulation curtain at the end of the refrigeration compartment near the door, the patent effectively reduces the loss of cold air inside the refrigeration compartment when the door is opened by staff and effectively blocks hot air from the outside, thereby effectively saving energy and improving the environmental and energy-saving effects of the device.
[0004] In the aforementioned patent, installing heat insulation curtains near the warehouse door effectively saves energy and reduces the loss of cold air inside the cold storage room. However, in actual operation, employees usually need to carry goods with both hands when retrieving them, making it difficult to free their hands to lift the heat insulation curtains when returning from the cold storage room. At this time, employees can only rely on their bodies to forcefully push open the heavy heat insulation curtains, which not only increases the difficulty of operation but also easily causes goods to fall or personnel to lose balance due to excessive force, affecting work efficiency and safety. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving partitioned cold storage, solving the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving partitioned cold storage unit, comprising a storage body, the outer wall of which is provided with a double-opening door. Employees open the double-opening door to enter the transition area of the storage body, and then close the double-opening door to ensure airtightness. The unit further comprises: a partition plate, which is fixedly installed inside the storage body and is used to divide the interior of the storage body into two areas. The area of the partition plate near the double-opening door is designated as the transition area, and the area of the partition plate away from the double-opening door is designated as the refrigeration area. An opening is provided on the partition plate, and the transition area and the refrigeration area are connected through the opening. A fixed frame is fixedly installed on the side of the partition plate near the double-opening door. A rotating plate is rotatably installed on the circumferential surface of the fixed frame, and the rotating plate contacts the outer wall of the partition plate. A heat-insulating curtain is fixedly installed at the bottom of the rotating plate, and the heat-insulating curtain is used to separate the transition area from the refrigeration area.
[0007] According to the above technical solution, a spiral spring is provided between the rotating plate and the fixed frame. The rotating plate stretches the spiral spring to produce elastic deformation. The deformed spiral spring stores elastic potential energy. The spiral spring is used to reset the rotating plate.
[0008] According to the above technical solution, a cylindrical rod is fixedly installed on the top of the rotating plate, and a support plate is fixedly installed on the side of the partition plate near the cylindrical rod. When the heat insulation curtain is pushed by the arm, the heat insulation curtain drives the rotating plate to rotate away from the support plate after being subjected to force. The inner wall of the support plate is provided with magnetic sheets.
[0009] According to the above technical solution, the cylindrical rod itself is magnetic. The cylindrical rod is in contact with the inner wall of the magnet plate. Under the magnetic attraction, the cylindrical rod is firmly placed inside the magnet plate, which enhances the static stability of the rotating plate at this time.
[0010] According to the above technical solution, the partition plate is provided with a self-locking device for limiting the rotation plate, and the fixed plate is provided with an auxiliary device for ensuring smooth operation. The self-locking device includes a fixed plate, one end of which is fixedly installed on the outer wall of the partition plate, and the other end of which is fixedly installed on the inner wall of the storage body. A through groove is opened on the surface of the fixed plate, and a sliding frame is slidably installed on the bottom of the fixed plate. A compression spring is provided between the sliding frame and the through groove of the fixed plate. A blocking plate is rotatably installed on the bottom of the sliding frame. The rotating plate contacts the blocking plate to prevent the rotating plate from resetting and keep the rotating plate in the open state. A limiting plate is fixedly installed on the bottom of the sliding frame. The limiting plate contacts the surface of the blocking plate, and the sliding frame contacts the inner wall of the through groove. A torsion spring is provided between the blocking plate and the sliding frame. A cylindrical rod contacts the blocking plate and pushes it to rotate. The rotation of the blocking plate stretches the torsion spring to produce elastic deformation. The torsion spring is used to reset the blocking plate.
[0011] According to the above technical solution, a push rod is fixedly installed at the bottom of the sliding frame. The push rod is manually pushed to make the sliding frame move synchronously. A linkage rod is fixedly installed at the top of the sliding frame, and the sliding frame drives the blocking plate and the linkage rod to move synchronously.
[0012] According to the above technical solution, the auxiliary device includes a base plate, a slide rail is fixedly installed on the top of the base plate, a sliding plate is slidably installed on the top of the slide rail, a sleeve is fixedly installed on the inner wall of the sliding plate, the sleeve is in contact with the circumferential surface of the linkage rod, the linkage rod drives the sleeve to move synchronously, and the sleeve further drives the sliding plate to move.
[0013] According to the above technical solution, a spring sheet is fixedly installed on the circumferential surface of the sleeve, a rectangular plate is fixedly installed on the top of the base plate, and several triangular blocks are fixedly installed on the side of the rectangular plate near the sleeve. The spring sheet contacts the inclined surface of the triangular block during movement, and the triangular block applies resistance to the spring sheet through the inclined surface, forcing the spring sheet to undergo elastic deformation.
[0014] This invention provides an energy-saving partitioned cold storage unit. It has the following beneficial effects:
[0015] (1) In this energy-saving partition cold storage, the rotating plate drives the heat insulation curtain to quickly return to its original position, effectively blocking the cold air leakage from the cold storage area. Through the rapid closing mechanism, it is ensured that the heat insulation curtain can immediately return to a sealed state after the employees pass through, shortening the air exchange time between the transition area and the cold storage area and reducing the loss of cold energy. At the same time, the heat insulation curtain can be easily opened to both sides, reducing the passage resistance when employees return. By rotating the heat insulation curtain to both sides, the passage resistance when employees return with goods can be reduced, so that employees do not need to stop to operate, effectively improving the handling efficiency of goods.
[0016] (2) Under the magnetic adsorption effect, the cylindrical rod of the energy-saving partition cold storage is firmly fixed in the magnetic plate. By enhancing the static stability of the rotating plate, it prevents the rotating plate from accidentally deflecting during daily use, which could lead to accidental leakage of cold air.
[0017] (3) In this energy-saving partition cold storage, the baffle plate prevents the rotating plate from resetting, keeping the rotating plate in the open state. By limiting the rotating plate, the heat insulation curtain is kept in the open state, forming an unobstructed passage, which makes it convenient for employees to quickly move goods from the transition area to the cold storage area. At the same time, the employee releases the push rod, and the spring releases its elasticity to push the sliding frame to reset. Through the elasticity of the spring, the employee can complete the unlocking and reset with a single push, reducing the complexity of the operation and preventing the sliding frame from accidentally shifting.
[0018] (4) In this energy-saving partition cold storage, the sliding plate transmits the supporting force to the linkage rod through the sleeve to form a stable moving state. By enhancing the overall stability of the sliding frame movement, it makes it easier for employees to push the push rod. At the same time, the process of the compression spring pushing the sliding frame to reset is also smoother. Meanwhile, the spring quickly rebounds and hits the triangular block. By using vibration to assist the movement of the sliding frame, it can effectively remove ice crystals on the surface and prevent the sliding frame from being in a low-temperature environment for a long time, which would cause the ice crystals on the surface to affect the stability of the movement.

[0028] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0029] Please see Figure 1 - Figure 4 One embodiment of the present invention is as follows: an energy-saving partitioned cold storage, including a storage body 1, with a double-opening door 2 on the outer wall of the storage body 1, and further including: a partition plate 3, which is fixedly installed inside the storage body 1, and is used to divide the interior of the storage body 1 into two areas. The area of the partition plate 3 near the double-opening door 2 is set as a transition area, and the area of the partition plate 3 away from the double-opening door 2 is set as a refrigerated area. The partition plate 3 has a passage opening, and the transition area and the refrigerated area are connected through the passage opening; a fixed frame 4, which is fixedly installed on the side of the partition plate 3 near the double-opening door 2; a rotating plate 5, which is rotatably installed on the circumferential surface of the fixed frame 4, and the rotating plate 5 is in contact with the outer wall of the partition plate 3; and a heat insulation curtain 6, which is fixedly installed at the bottom of the rotating plate 5. The heat insulation curtain 6 is used to block the transition area and the refrigerated area. By rotating the heat insulation curtain 6 to both sides, the passage resistance when employees return with goods can be reduced, so that employees do not need to stop to operate, effectively improving the handling efficiency of goods.
[0030] A spiral spring is installed between the rotating plate 5 and the fixed frame 4. The spiral spring is used to reset the rotating plate 5. By installing the spiral spring, it is ensured that after the employee pushes open the heat insulation curtain 6, the heat insulation curtain 6 can automatically close the passage to prevent cold air from leaking out.
[0031] A cylindrical rod 7 is fixedly installed on the top of the rotating plate 5. A support plate 8 is fixedly installed on the side of the partition plate 3 near the cylindrical rod 7. A magnetic piece 9 is provided on the inner wall of the support plate 8. Through the quick closing mechanism, it is ensured that the heat insulation curtain 6 can be restored to a sealed state immediately after the employee passes through, shortening the air exchange time between the transition zone and the refrigeration zone and reducing the loss of cold energy.
[0032] The cylindrical rod 7 itself is magnetic. The cylindrical rod 7 contacts the inner wall of the magnet plate 9, which enhances the static stability of the rotating plate 5 and prevents the rotating plate 5 from accidentally deflecting during daily use, thus preventing accidental leakage of cold air.
[0033] In this embodiment, during operation, employees open the double-leaf door 2 to enter the transition area of the warehouse 1, and then close the double-leaf door 2 to ensure airtightness. When retrieving goods, they manually open the heat insulation curtain 6 to enter the refrigerated area. When employees return to the transition area with goods, they push the heat insulation curtain 6 with their arms. After being subjected to force, the heat insulation curtain 6 drives the rotating plate 5 to rotate away from the support plate 8. At this time, the rotating plate 5 stretches the spiral spring, causing it to undergo elastic deformation, and drives the cylindrical rod 7 to separate from the magnet 9, allowing the heat insulation curtain 6 to open easily to both sides, reducing the resistance to passage when employees return. This is especially convenient for employees carrying goods with both hands to pass through quickly. By rotating the heat insulation curtain 6 to both sides, the resistance to passage when employees return with goods can be reduced, allowing employees to operate without stopping. This effectively improves the efficiency of goods handling. When employees move to the transition area through partition plate 3, the elastic restoring force of the spiral spring drives the rotating plate 5 to rotate. The rotating plate 5 drives the heat insulation curtain 6 to quickly return to its initial closed position, effectively preventing the cold air from leaking out of the refrigerated area. At the same time, the rotating plate 5 drives the cylindrical rod 7 to rotate synchronously, so that it contacts the inner wall of the magnetic plate 9. Under the magnetic attraction, the cylindrical rod 7 is firmly fixed in the magnetic plate 9, enhancing the static stability of the rotating plate 5 at this time and preventing the rotating plate 5 from accidentally deflecting during daily use, which would cause the cold air to leak unexpectedly. Through the rapid closing mechanism, it is ensured that the heat insulation curtain 6 can immediately return to a sealed state after the employees pass through, shortening the air exchange time between the transition area and the refrigerated area and reducing the loss of cold energy.
[0034] Please see Figure 1 - Figure 8 In another embodiment of the present invention, based on the above embodiments, the partition plate 3 is provided with a self-locking device for limiting the rotation plate 5, and the fixed plate 21 is provided with an auxiliary device for ensuring smooth operation. The self-locking device includes a fixed plate 21, one end of which is fixedly installed on the outer wall of the partition plate 3, and the other end of which is fixedly installed on the inner wall of the storage body 1. A through groove is provided on the surface of the fixed plate 21, and a sliding frame 22 is slidably installed on the bottom of the fixed plate 21. A compression spring 23 is provided between the sliding frame 22 and the through groove of the fixed plate 21. A blocking plate 24 is rotatably installed on the bottom of the sliding frame 22, and a limiting plate 25 is fixedly installed on the bottom of the sliding frame 22. The limiting plate 25 is in contact with the surface of the blocking plate 24, and the sliding frame 22 is in contact with the inner wall of the through groove. A torsion spring is provided between the blocking plate 24 and the sliding frame 22. The torsion spring is used to reset the blocking plate 24. By limiting the rotation plate 5, the heat insulation curtain 6 is kept in the open state, forming an unobstructed passage, which facilitates employees to quickly move goods from the transition area to the cold storage area.
[0035] A push rod 26 is fixedly installed at the bottom of the sliding frame 22, and a linkage rod 27 is fixedly installed at the top of the sliding frame 22. Through the elastic force of the compression spring 23, the employee can complete the unlocking and resetting with a single push, reducing the complexity of the operation and preventing the sliding frame 22 from accidentally shifting.
[0036] The auxiliary device includes a base plate 31, a slide rail 32 fixedly mounted on the top of the base plate 31, a sliding plate 33 slidably mounted on the top of the slide rail 32, and a sleeve 34 fixedly mounted on the inner wall of the sliding plate 33. The sleeve 34 contacts the circumferential surface of the linkage rod 27, thereby enhancing the overall stability of the sliding frame 22 movement, making it easier for employees to push the push rod 26, and at the same time, the process of the compression spring 23 pushing the sliding frame 22 to reset is also smoother.
[0037] A spring piece 35 is fixedly installed on the circumferential surface of the sleeve 34, and a rectangular plate 36 is fixedly installed on the top of the base plate 31. Several triangular blocks 37 are fixedly installed on the side of the rectangular plate 36 near the sleeve 34. By using vibration to assist the movement of the sliding frame 22, the ice crystals on the surface can be effectively removed, preventing the sliding frame 22 from being in a low-temperature environment for a long time, which would cause the ice crystals on the surface to affect the stability of the movement.
[0038] In this embodiment, when restocking is needed, employees first stack the goods in the transition area and close the double-leaf door 2. Then, the employee pulls the rotating plate 5 towards the fixed plate 21. The rotating plate 5 rotates, stretching the spiral spring and causing the cylindrical rod 7 to rotate synchronously. During this process, the cylindrical rod 7 contacts the blocking plate 24 and pushes it to rotate. The blocking plate 24 rotates, stretching the torsion spring and causing it to elastically deform. When the cylindrical rod 7 completely separates from the blocking plate 24, the deformed torsion spring causes the blocking plate 24 to return to its initial position. At this time, the employee releases the rotating plate 5. The restoring force of the spiral spring drives the rotating plate 5 to rotate back. During the resetting process, the rotating plate 5 contacts the blocking plate 24, and the blocking plate 24 is limited by the limiting plate 25, preventing the rotating plate 5 from resetting and keeping it in the open state. This facilitates the employee moving the stacked goods to the cold storage area. By limiting the rotating plate 5, the employee can... The heat insulation curtain 6 remains open, forming an unobstructed passage for employees to quickly move goods from the transition area to the refrigerated area. After restocking, employees manually push the push rod 26, causing it to move the sliding frame 22 synchronously. During this process, the sliding frame 22 compresses the spring 23, causing it to deform elastically. At the same time, the sliding frame 22 moves the blocking plate 24 and the linkage rod 27 synchronously. As the blocking plate 24 moves, it releases its obstruction of the cylindrical rod 7. At this time, the rotating plate 5 returns to its initial position under the restoring force of the spiral spring. After the rotating plate 5 resets, the employee releases the push rod 26, and the spring 23 releases its elastic force to push the sliding frame 22 back to its original position. The sliding frame 22 moves the blocking plate 24 and the linkage rod 27 back to their original positions synchronously. Through the elastic force of the spring 23, employees can complete the unlocking and reset with a single push, reducing the complexity of the operation and preventing the sliding frame 22 from accidentally shifting.
[0039] When the linkage rod 27 moves, it drives the sleeve 34 to move synchronously. The sleeve 34 further drives the sliding plate 33 to move. The sliding plate 33 moves smoothly along the slide rail 32. The slide rail 32 provides support and guidance for the sliding plate 33, ensuring that the linkage rod 27 does not deviate when it moves. At the same time, the sliding plate 33 transmits the supporting force to the linkage rod 27 through the sleeve 34, forming a stable moving state. By enhancing the overall stability of the sliding frame 22's movement, it makes it easier for employees to push the push rod 26. At the same time, the process of the compression spring 23 pushing the sliding frame 22 to reset is also smoother. When the sleeve 34 moves, it drives the spring piece 35 to move synchronously. The spring piece 35 interacts with the triangular block 37 during its movement. When the inclined surfaces make contact, the triangular block 37 applies resistance to the spring piece 35 through the inclined surface, forcing the spring piece 35 to undergo elastic deformation. When the spring piece 35 separates from the triangular block 37, the spring piece 35 releases its stored elastic potential energy, causing the spring piece 35 to rebound quickly and collide with the next triangular block 37. Then the above movement is repeated, and the collision with several triangular blocks 37 forms intermittent vibration. The vibration acts on the linkage rod 27 and the sliding frame 22 as a whole through the sleeve 34, effectively breaking the ice crystals on the contact surface and preventing movement jamming in low temperature environments. By using vibration to assist the movement of the sliding frame 22, the ice crystals on the surface can be effectively removed, preventing the sliding frame 22 from being in a low temperature environment for a long time, which would cause the ice crystals on the surface to affect the stability of movement.
