[0032] In the prior art, the cold storage tank is provided with a generator set and a refrigerating unit, and the generator set generates power for the refrigerating unit to refrigerate and preserve fresh; however, the refrigerating unit is bulky and is easy to be damaged in the transportation process due to jolting, which increases the difficulty of fresh-keeping transportation of agricultural products; at the same time, the process of generating power for the refrigerating unit by the generator set will cause high energy consumption, resulting in the increase of the cost of fresh-keeping transportation of agricultural products.

[0033] In order to solve the above technical problems, the utility model provides a cold storage tank structure.

[0034] Please refer to Figure 1 In an embodiment of the utility model, the cold storage tank structure comprises:

[0035] The tank body 100 is divided into a refrigeration area 120 and a storage area 130 by a partition plate 110 inside the tank body 100;

[0036] The ice box 200 is arranged in the refrigeration area 120;

[0037] The air outlet duct 300 and the air return duct 400 are arranged on the partition plate 110; the air outlet duct 300 is used for guiding the cold air generated by the ice box 200 in the refrigeration area 120 to the storage area 130; and the air return duct 400 is used for guiding the air in the storage area 130 to the refrigeration area 120, so as to form an air loop between the refrigeration area 120 and the storage area 130.

[0038] The technical scheme of the utility model discloses a mode that the ice box 200 replaces the refrigeration unit, and the cold air generated by the ice box 200 flows to the storage area 130 through the air outlet duct 300 to preserve and refrigerate the agricultural products stored in the storage area 130; then the excess cold air flows to the refrigeration area 120 through the air return duct 400 to form an air loop. Understandably, compared with the refrigeration unit, the ice box is smaller in size and is not easy to be damaged in the transportation process, so as to realize the purpose of reducing the difficulty of agricultural product preservation and transportation. In addition, since the refrigeration unit is omitted, the generator set in the application also does not need to generate power for the refrigeration unit, so as to avoid the high energy consumption of the generator set and reduce the transportation cost.

[0039] The ice box 200 is made of plastic PE material or HDPE material, which is hard and has good plasticity, so as to ensure the durability and stability of the ice box during use; the content of the ice box is refrigerant, which is usually prepared by high-tech biological material or high-molecular phase change cold storage material, and is clean and non-toxic, and has excellent cold preservation performance; the ice box has excellent cold preservation performance, and the effective use of cold capacity is 3-5 times of ice, or even 6 times of ice of the same volume, so as to maintain a low-temperature environment for a long time. At the same time, the ice box has small deformation after freezing, can be reused, and has good plasticity; the ice box is widely used in the fields of cold storage and preservation of food and medicine, low-temperature cold chain transportation and the like.

[0040] In the embodiment, the air outlet duct 300 is located on the upper side of the partition plate 110, and the air return duct 400 is located on the lower side of the partition plate 110; in this way, since the cold air is heavy and flows downward, the cold air flowing out of the air outlet duct 300 flows downward under the action of gravity to refrigerate and transport the agricultural products below.

[0041] Further, the ice box 200 is made by pre-freezing; in this way, the ice box 200 is made by pre-freezing, so that the preservation and transportation of agricultural products is more flexible; it can be understood that, due to weather and climate and labor efficiency, the preservation and transportation time of agricultural products cannot be accurately determined, and if the ice box 200 is frozen after the preservation and transportation time is determined, the preservation and transportation will be delayed; for the above reasons, the ice box 200 needs to be pre-frozen.

[0042] Further, the ice box 200 is pre-frozen in the low valley period of peak-valley electricity price. In this way, since the electricity fee is lower in the low valley period of peak-valley electricity price, the pre-frozen ice box 200 in the low valley period can reduce the freezing cost of the ice box 200, and further reduce the transportation cost of the agricultural product fresh-keeping transportation.

[0043] Specifically, the air outlet duct 300 is provided with an air inducer 310. Under the driving action of the air inducer 310, the cold air generated by the ice box 200 flows from the refrigeration area 120 to the storage area 130. In this way, the air inducer 310 is used as a power source, so that the cold air generated by the ice box 200 can flow from the refrigeration area 120 to the storage area 130, to fresh-keep the agricultural products in the storage area 130, thereby ensuring the smooth implementation of the technical scheme of the present application.

[0044] Specifically, the air return duct 400 is provided with a baffle 410, and the baffle 410 is slidably connected with the air return duct 400 to enable the baffle 410 to close or open the air return duct 400. In this way, in the initial stage of refrigeration, in order to ensure that the cold air can quickly fill the entire storage area 130, the air return duct 400 is first closed by the baffle 410 to avoid the cold air flowing back to the refrigeration area 120.

[0045] Specifically, the air return duct 400 is provided with an air speed meter 420, and the air speed meter 420 is electrically connected with the air inducer 310. In this way, the air speed meter 420 is used to monitor the air speed in the air return duct 400 to determine the gas flow condition between the storage area 130 and the refrigeration area 120, and the air inducer 310 is controlled according to the monitoring data of the air speed meter 420, so that the cold air can effectively flow from the refrigeration area 120 to the storage area 130 to fresh-keep the agricultural products in the storage area 130.

[0046] As a preferred scheme of the above-mentioned embodiment, reference is made to the accompanying drawings Figure 2 The storage area 130 is provided with a temperature and humidity sensor 500, and the temperature and humidity sensor 500 is electrically connected with the air inducer 310. In this way, the temperature and humidity sensor 500 is used to monitor the temperature and humidity of the storage area 130 to ensure that the temperature and humidity of the storage area 130 meet the fresh-keeping transportation requirements of the agricultural products.

[0047] Further, the storage area 130 comprises a plurality of groups of temperature and humidity sensor groups 510, which are spaced apart along the length direction of the storage area 130 and arranged inside the storage area 130; each group of temperature and humidity sensor groups 510 comprises five temperature and humidity sensors 500, four of which are arranged on the upper, lower, left and right sides of the frame-shaped structure respectively, and the remaining one is arranged in the middle of the frame-shaped structure. In this way, the temperature and humidity sensors 500 can effectively monitor the temperature and humidity of each space area of the storage area 130, so as to avoid the damage of agricultural products caused by the temperature or humidity of a certain space area not meeting the fresh-keeping transportation requirements.

[0048] As a preferred scheme of the above-mentioned embodiment, reference is made to the accompanying drawings Figure 3 The refrigeration area 120 is provided with a placing rack 600 for carrying the ice box 200; specifically, the placing rack 600 comprises a plurality of placing plates 610 arranged in the vertical direction, and each placing plate 610 is provided with at least one placing area 611 for placing the ice box 200. In this way, a plurality of ice boxes 200 are placed on the placing areas 611 of the placing plates 610, so that the cold air generated by the combination of the plurality of ice boxes 200 can effectively preserve the agricultural products for transportation. In this embodiment, each placing plate 610 is provided with one placing area 611.

[0049] Further, the placing plate 610 is provided with a plurality of through air holes 620, and the air holes 620 are distributed on the outer periphery of the placing area 611; the air holes 620 are used for the cold air generated by the ice box 200 to pass through. In this way, since the placing plates 610 in this embodiment are arranged in the vertical direction, it is necessary to open a plurality of through air holes 620 on the placing plate 610 and distribute the air holes 620 on the outer periphery of the placing area 611, so as to ensure that the cold air can pass through the air holes 620 and flow to the air outlet 300 above the partition plate 110 through the plurality of placing plates 610.

[0050] Further, the left and right sides of the placement area 611 are respectively provided with a limiting piece 630, and the two limiting pieces 630 are combined to limit the left and right sides of the ice box 200; and the top of the limiting piece 630 is telescopically connected with a claw body 640, the free end of the claw body 640 is provided with a bent portion 650, the bent portion 650 extends to the upper area of the ice box 200, and the bent portion 650 is used to press the top of the ice box 200. In this way, the claw body 640 at the top of the limiting piece 630 is first stretched upward, then the ice box 200 is placed between the two limiting pieces 630 on the left and right sides of the placement area 611, and the two limiting pieces 630 are combined to avoid the left and right displacement of the ice box 200; then the claw body 640 is loosened to make the claw body 640 retract to the top of the limiting piece 630, so that the bent portion 650 of the claw body 640 presses the top of the ice box 200, thereby fixing the ice box 200 in the placement area 611 to avoid the ice box 200 from shaking due to road bumps during transportation and colliding with the inner wall of the box body 100 to cause damage.

[0051] Among them, there are many telescopic connection structures of the limiting piece 630 and the claw body 640, and in the embodiment, the telescopic connection structure of the limiting piece 630 and the claw body 640 is as follows: Figure 4 The inside of the limiting piece 630 is provided with a sliding cavity 631, the opening end of the sliding cavity 631 is provided with a first limiting ring 632; the claw body 640 is provided with a sliding rod 641, the free end of the sliding rod 641 penetrates through the first limiting ring 632 and is slidingly connected in the sliding cavity 631, and the free end of the sliding rod 641 is sleeved with a second limiting ring 642, the first limiting ring 632 and the second limiting ring 642 abut each other; the sliding rod 641 is sleeved with a spring piece 643, and the upper and lower ends of the spring piece 643 abut the first limiting ring 632 and the second limiting ring 642 respectively. In this way, when the claw body 640 is stretched upward, the sliding rod 641 moves upward along the sliding cavity 631 until the first limiting ring 632 and the second limiting ring 642 abut each other, and during this period, the spring piece 643 located between the first limiting ring 632 and the second limiting ring 642 is elastically compressed; after the force on the claw body 640 is removed, the claw body 640 approaches the limiting piece 630 along the sliding cavity 631 under the elastic action of the spring piece 643, so as to realize the retraction of the claw body 640; at the same time, the bent portion 650 of the claw body 640 can press the ice box 200 under the elastic action of the spring piece 643, so as to realize the pressing and fixing of the ice box 200 in the placement area 611.
