DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments to make the purpose, technical solutions and advantages of the present invention more clearly understood. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0031] refer to Figure 1 The cold storage shelf device of the exemplary embodiment of the present invention includes a vertical support frame 1 and a horizontal support frame 2. The two sets of vertical support frames 1 are arranged opposite to each other, and one or more layers of mutually parallel horizontal support frames 2 are arranged between the two sets of vertical support frames 1. A cold storage device 3 is arranged on each layer of horizontal support frame 2, and one or more protrusions 31 are arranged on the outer surface of the cold storage device 3 (refer to Figure 3 ), the internal cavity of the protrusion 31 is connected to the cold storage device 3.

[0032] The cold storage shelf device of the present invention supports articles through the horizontal support frame 2 and stably supports the horizontal support frame 2 through the vertical support frame 1, thereby ensuring the stability of the articles on the cold storage shelf device. The cold storage device 3 on the horizontal support frame 2 can work after the mechanical refrigeration device fails, so that the temperature in the cold storage meets the requirements for storing articles and prevents damage to articles; under the action of the cold storage device 3, the mechanical refrigeration device can also be avoided from working continuously, thereby reducing energy consumption; the raised portion on the cold storage device 3 increases the surface area of ​​the cold storage device 3, thereby increasing the contact area with the air, and under the same conditions, the heat absorption effect of the cold storage device 3 can be improved, further reducing the working energy consumption of the mechanical refrigeration device.

[0033] Each group of vertical support frames 1 includes one or more bracket units 11, and each bracket unit 11 includes two oppositely arranged pillars 110. The two pillars 110 are connected by a cross bar 111 and / or a diagonal bar 112 to ensure the stability of the bracket unit 11 structure and the structural strength of the bracket unit 11; when each group of support frames includes multiple bracket units 11, the multiple bracket units 11 are detachably connected in sequence from low to high (detachably connected by bolts or other connecting parts) to adjust the overall height of the vertical support frame 1, so that the vertical support frame 1 can adjust its own height according to the size of the cold storage space, and can also enable the vertical support frame 1 to meet the placement requirements of goods of different sizes.

[0034] The cross-sectional shape of the pillar 110 is a U-shaped structure. A plurality of connecting through holes 113 are provided on each side of the pillar 110 along the height direction of the pillar 110. The connecting through holes 113 on each side of the pillar 110 can be at the same height position or at different height positions. The pillars 110 of adjacent bracket units 11 can be connected through the connecting through holes 113, and the horizontal support frame 2 and the pillar 110 can also be detachably connected. According to the height size of the items, the distance between adjacent layers of horizontal support frames 2 can be adjusted so that the space between adjacent layers of horizontal support frames 2 can meet the storage requirements of the items, thereby increasing the flexibility of the use of the cold storage shelf device.

[0035] refer to Figure 2 The horizontal support frame 2 includes two parallel main beams 21, which are detachably connected by a plurality of parallel secondary beams 22 to ensure the structural stability of the horizontal support frame 2. The secondary beams 22 are perpendicular to the main beams 21. Connecting portions 23 are symmetrically provided at both ends of each main beam 21. These connecting portions 23 are provided with mounting holes (not shown). These connecting portions 23 allow for detachable connection (via bolts or other connectors) between the horizontal support frame 2 and the support column 110 of the vertical support frame 1, thereby adjusting the installation height of the horizontal support frame 2 on the vertical support frame 1. The connecting portion 23 has an L-shaped cross-section. The first side of the connecting portion 23 is welded or bolted to the main beam 21, and the second side of the connecting portion 23 is bolted to the support column 110.

[0036] Mounting grooves 211 are respectively provided on the surfaces of the two main beams 21 that are close to each other. The two ends of the secondary beam 22 are respectively extended into the mounting grooves 211 of the main beam 21 and are detachably connected to the main beam 21. The main beam 21 is provided with multiple connecting holes (not shown in the figure) along the length direction. When the main beam 21 and the secondary beam 22 are connected, bolts can be passed through the main beam 21 and the secondary beam 22 at the same time to fix the main beam 21 and the secondary beam 22. The cold storage device 3 can be arranged between adjacent secondary beams 22. When arranged between adjacent secondary beams 22, the distance between adjacent secondary beams 22 can be adjusted so that the installation of the cold storage device 3 meets the storage requirements of items; when the cold storage device 3 is arranged between adjacent secondary beams 22, the opposite ends of the cold storage device 3 are respectively embedded in the installation grooves 211, and the installation grooves 211 of the main beam 21 can provide stable support for the cold storage device 3; when installing the cold storage device 3 on the main beam 21, the order of the secondary beam 22 and one or more cold storage devices 3 can be used alternately. Since the secondary beam 22 is fixedly connected to the main beam 21, the stability of the installation of the cold storage device 3 can be guaranteed under the action of the installation grooves 211 on the secondary beam 22 and the main beam 21.

[0037] The thickness of the secondary beam 22 is greater than that of the cold storage 3. When placing items on the horizontal support frame 2, the surface of the items contacts the main beam 21 or the secondary beam 22, avoiding direct contact between the surface of the items and the surface of the cold storage 3, thereby preventing damage to the items. During use, when the distance between adjacent secondary beams 22 is greater than the width of the items to be placed and the items contact the cold storage 3, a punching plate 24 can be laid along the length direction of the main beam 21 (refer to Figure 7 ), the punching plate 24 is detachably connected to the main beam 21 or the secondary beam 22. The punching plate 24 can prevent the surface of the object from contacting the surface of the cold storage device 3, and can also enable the cold storage device 3 to evenly absorb the heat of the environment surrounding the cold storage device 3, thereby preventing damage to the object and preventing the cold storage device 3 from being crushed by the heavy weight of the object.

[0038] The cold storage tank 3 is a tubular structure or a hexahedral structure. When the cold storage tank 3 is a tubular structure, a plurality of arc-shaped protrusions 31 are provided on the outer surface of the cold storage tank 3 along the length direction of the cold storage tank 3 (refer to FIG. Figure 3 ), each group of raised portions 31 is arranged along the circumference of the cold accumulator 3; when the cold accumulator 3 is a hexahedron structure, the cold accumulator 3 is preferably a box structure with a rectangular cross section, and multiple rows of raised portions 31 with arc-shaped cross sections are respectively arranged on the top surface and / or bottom surface of the cold accumulator 3 (refer to Figure 4 ) or multiple rows of raised portions 31 with rectangular or trapezoidal cross sections (reference Figure 5 、 Figure 7), adjacent rows of protrusions 31 have a certain spacing, and the spacing width of adjacent rows of protrusions 31 is preferably not greater than the maximum width of the protrusions 31 (it can also be greater than the maximum width of the protrusions 31), so as to further increase the surface area of ​​the cold accumulator 3 and improve the heat absorption effect of the cold accumulator 3; when the top and bottom surfaces of the cold accumulator 3 are both provided with protrusions 31, the protrusions 31 on the top surface of the cold accumulator 3 and the protrusions on the bottom surface of the cold accumulator 3 are on the same axis or staggered with each other.

[0039] The thickness of the raised portion 31 is not greater than 1 / 2 of the thickness of the cold storage 3, so that the cold storage 3 can fully absorb heat and prevent the items on the horizontal support frame 2 from being damaged. When the cold storage 3 is a hexahedral structure, a cold storage hole 32 is also provided on the cold storage 3 (refer to Figure 6 ), the wall of the cold storage hole 32 can also absorb ambient heat, further improving the cold storage effect. Furthermore, the cold storage device 3 is also provided with a filling port, which is sealed by a sealing cover (not shown in the figure). The phase change cold storage material can be filled into the cold storage device 3 through the filling port. The filling volume of the phase change cold storage material in the cold storage device 3 is 80% to 90% of the volume of the cold storage device 3, so that the internal space of the cold storage device 3 can accommodate the volume change of the phase change cold storage material during the phase change process. In the cold storage, the mechanical refrigeration device will cause the phase change cold storage material in the cold storage device 3 to store cold. After the mechanical refrigeration device stops working, the phase change cold storage material will cause the cold storage device 3 to absorb heat from the surface of the objects, thereby preventing damage to the objects on the horizontal support frame 2. When the cold storage device 3 adopts a tubular structure, the filling port is set on the bottom or side of the cold storage device 3. When the cold storage device 3 adopts a hexahedral structure, the filling port is set on the top, bottom or side of the cold storage device 3.

[0040] When the cold storage device 3 adopts a hexahedral structure, the cold storage device 3 can also be set in the installation groove 211 of the main beam 21. When the cold storage device 3 is installed on the main beam 21, it can also be installed in the order of the secondary beam 22, one or more cold storage devices 3, and so on. Figure 9 When the horizontal support frame structure shown in the figure is adopted, a punching plate can also be used to connect with the main beam 21 or the secondary beam 22, and the two ends of the cold storage device 3 are respectively embedded in the installation groove 211. The protrusion on the cold storage device 3 can be set along the direction of the main beam 21 or perpendicular to the main beam 21. In order to improve the structural strength of the horizontal support frame 2 and make the cold storage device 3 on the horizontal support frame 2 store cold evenly, the secondary beam 22 can be installed at the bottom or top of the main beam 21. The structural strength of the horizontal support frame 2 is ensured by the secondary beam 22, and then a removable barrier rod 25 (reference Figure 10), a barrier rod 25 is arranged near the first end of the main beam 21, and the two ends of the barrier rod 25 are respectively embedded in the installation groove 211, and then the cold storage devices 3 are installed in sequence along the length direction of the main beam 21. The width of the installation groove 211 corresponds to the thickness of the cold storage devices 3, and the surfaces of each cold storage device 3 fit together so that the cold storage devices 3 store cold evenly. After the cold storage devices 3 are installed, a removable barrier rod 26 is installed at the second end near the main beam 21 to prevent the cold storage devices 3 from moving in the installation groove 211; when the secondary beam 22 is installed on the top of the main beam 21, the secondary beam 22 can separate the items on the horizontal support frame 2 from the cold storage devices 3. According to the weight of the items to be stored, the number of secondary beams 22 can be increased and the spacing between adjacent secondary beams 22 can be reduced so that the load-bearing capacity of the horizontal support frame 2 meets the use requirements.
