For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] An energy-saving cold storage for cold chain preservation, such as Figures 1 to 11 As shown, it includes a warehouse body 1, and wall panels 2 are respectively provided at the front and rear ends of the warehouse body, and warehouse doors 3 are installed on the wall panels, wherein at least one end of the wall panel can be detachably installed on the warehouse body. As an example, four screws 4 are respectively provided at the four corners of the end face of the warehouse body, and the wall panels corresponding to the screws are respectively provided with holes 22, and the wall panels are locked by nuts 5 screwed on the ends of the screws, that is, the wall panels are locked by nuts screwed on the outer parts of the wall panels exposed by the screws, so that the warehouse body and the wall panels at the front and rear ends are combined into a whole. The screws are preset in the wall panels on the left and right sides of the warehouse body when the warehouse body is manufactured. In order to improve the sealing between the warehouse body and the wall panels, a heat preservation pad 6 can be set on the end face of the warehouse body. As an example, the heat preservation pad can be a wool felt heat preservation pad.

[0035] A partition 7 is provided in the storage body, and independent chambers 23 are formed on both sides of the partition, one side of the partition is used as a working chamber, and the other side is used as an idle chamber. A seal 8 is installed on the partition corresponding to the inner wall of the storage body, and at least two sets of walking mechanisms 9 are provided at the lower part of the partition; the seal is arranged around the outer edge of the partition, that is, the seal is arranged around the four end faces of the partition, such that the outer periphery of the partition forms an integral sealing structure, ensuring reliable sealing between the outer periphery of the partition and the inner wall of the storage body.

[0036] Specifically, the seal includes a base 10 and a sealing structure 11 on the periphery of the base, the sealing structure includes a main sealing portion 12 in the middle, and auxiliary sealing portions 13 on both sides of the main sealing portion, and the main sealing portion protrudes from the auxiliary sealing portions on both sides. A sealing installation groove 24 is provided on the outer edge of the partition, and the sealant is installed in the sealing installation groove. The two auxiliary sealing portions are symmetrically arranged on both sides of the main sealing portion. Usually, the base of the seal and the peripheral sealing structure are an integrally molded structure. The seal is made of rubber material, preferably a low-temperature resistant rubber material. As an example, the low-temperature resistant rubber material includes but is not limited to chloroprene rubber.

[0037] In actual application, the base of the seal is installed in the seal installation groove, and the base is compressed by the clamping screws 18 arranged in the corresponding grooves on the surface of the partition to ensure the stability of the seal structure. In order to isolate the heat exchange of the chambers on both sides of the partition, in an optional embodiment, the partition includes an outer shell, the inside of the outer shell is filled with thermal insulation cotton, and the seal installation grooves are arranged on the end caps around the outer shell. The partition filled with thermal insulation cotton has stronger thermal insulation capabilities than ordinary plates. The sealing structure of the seal is exposed in the seal installation groove, and contacts with the inner wall of the storage body through the sealing structure to form a good seal, thereby ensuring that the chambers on both sides of the partition are independent of each other and there is no heat exchange. Usually, the two auxiliary sealing parts of the seal are highly consistent.

[0038] The thickness of the main sealing part of the seal gradually decreases from one side of the base to the outside. The thickness of the main sealing part refers to the size of the main sealing part in the thickness direction of the partition. In the process of pushing the partition to move, the main sealing part is allowed to bend in the direction opposite to the moving direction, and the tip of the main sealing part is tightly attached to the auxiliary sealing part on the side away from the moving direction, so that the sealing structure and the inner wall of the warehouse are reliably sealed. When used, the seal on the partition fits the inner wall of the warehouse, and cavities are formed between the main sealing part and the auxiliary sealing parts on both sides, which can effectively prevent heat exchange, reduce refrigeration capacity, and save energy and protect the environment.

[0039] like Figure 7 As shown, the walking mechanism includes walking wheels 14 symmetrically arranged on both sides of the partition, and the walking wheels are installed on the partition through a bracket. The bracket includes a wheel frame 16 and a fixing seat 17, and a height adjustment mechanism is provided between the fixing seat and the wheel frame. It should be pointed out that the walking wheels are symmetrically arranged on both sides of the partition, and the walking wheels are installed on the partition through a bracket, that is, there is a certain distance between the two walking wheels of each set of walking mechanisms. Therefore, the at least two sets of walking mechanisms provided can continuously and stably keep the partition upright without tipping over, thereby ensuring a stable seal between the seal on the outside of the partition and the inner wall of the warehouse.

[0040] In an optional embodiment, the height adjustment mechanism includes an adjustment member 19 on the fixed seat, and a support member 20 is symmetrically provided on both sides of the adjustment member on the fixed seat. As an example, the adjustment member is a screw rod, and the support member is a screw. The wheel frame is slidably installed in the groove 15 at the lower part of the fixed seat, the lower end of the adjustment member is fixed to the top of the wheel frame, and the upper end passes through the fixed seat upward, and a nut 21 is screwed on the end passing through the fixed seat upward. The support member is screwed on the fixed seat, and the end of the support member extending downward into the groove of the fixed seat is against the top of the wheel frame.

[0041] When adjusting the height of the travel wheel upward, you only need to loosen the top holding piece first, that is, screw the top holding piece upward to move the top holding piece upward to the appropriate position, and then tighten the nut to move the adjustment piece upward until the wheel frame abuts against the top holding piece, and the travel wheel is at the desired height position to complete the adjustment. When adjusting the height of the travel wheel downward, you only need to loosen the nut to move the adjustment piece downward, and then tighten the top holding piece, that is, screw the top holding piece downward, so that the lower end of the top holding piece abuts against the top of the fixing seat to achieve the positioning of the fixing seat, and the travel wheel is at the desired height position to complete the adjustment.

[0042] The walking mechanism is set at the bottom of the partition, which can easily push the partition to adjust the chamber volume, which is easy to operate, saving time and effort. At the same time, the partition is supported by the walking mechanism to avoid sinking due to the weight of the partition, which causes poor sealing on the upper side of the partition. By adjusting the height of the walking wheel, it can be ensured that the seal can form a stable seal with the warehouse body on both the upper and lower sides of the partition.

[0043] Preferably, the travel wheel is a universal wheel with a built-in brake device. Before moving the partition, the brake of the travel wheel is first released. After pushing the partition to the desired position, the travel wheel can be re-fixed by the brake device to prevent the partition from moving at will. It should be noted that handles are provided on the front and rear surfaces of the partition, and the partition can be conveniently pushed by holding the handles.

[0044] In an optional embodiment, two partitions can be set in a storage body. By moving the position of the partitions, a suitable working chamber can be obtained at each end of the storage body, that is, an idle chamber is formed between the two partitions, and the side of each partition that is different from the idle chamber is a working chamber, thereby realizing the classified storage of different cold chain fresh-keeping products.

[0045] The utility model has a simple structure and reasonable design. The volume of the working chamber in the storage body can be adjusted by pushing the partition according to the total amount of cold chain preservation products and storage requirements. The temperature, humidity and other control equipment of the cold storage only need to control the environment of the working chamber, and the idle chamber on the other side of the partition no longer generates energy consumption, which not only improves the refrigeration effect in the working chamber, but also achieves energy saving and environmental protection, so as to reduce the cost of cold chain preservation. In addition, the partition is very convenient to move, easy to operate, time-saving and labor-saving, and because there is no connection between the partition and the storage body, the partition can be taken out of the storage body by removing the wall panel on one side, which is convenient for transfer to other cold storage or application to other working conditions.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
