Description
Technical Field
[0001] The utility model relates to the technical field of cold chain equipment, in particular to a divided-chamber self-circulating cold chain transport box. Background Art
[0002] The compartmentalized self-circulating cold chain transport box is an advanced transport equipment with many advantages. Structurally, the compartmentalized design can store items in categories to avoid mutual influence, and can also achieve temperature zone control to meet the specific temperature requirements of different items; the self-circulating system can maintain a stable temperature, even if the external ambient temperature fluctuates greatly, it can maintain a low internal temperature, and it is energy-efficient and efficient, reducing dependence on external energy. In terms of application areas, it is widely used in the pharmaceutical industry, providing reliable transportation guarantees for drugs, vaccines, etc.; in the food industry, it can transport fresh and frozen foods to maintain freshness and quality; in the scientific research field, it can also be used to transport experimental samples and biological products. In general, the compartmentalized self-circulating cold chain transport box has precise temperature control, high reliability, strong flexibility, and is energy-saving and environmentally friendly.
[0003] At present, conventional compartmentalized self-circulating cold chain transport boxes face some challenges in practical applications. First, due to the limitations of the internal space of the box, its self-circulation capacity is relatively weak, which leads to a certain degree of energy waste. Specifically, after the refrigerant (ice cubes, etc.) absorbs heat and evaporates, these vapors are usually enclosed in an isolated storage space, and heat exchange and refrigeration are carried out only by conduction, without effectively utilizing the refrigerant, thereby reducing the energy efficiency of the overall system. In addition, after melting, the refrigerant is stored in an isolated cavity and is not reused in other ways.
[0004] To this end, the utility model provides a compartmentalized self-circulating cold chain transport box to solve the above problems. Utility Model Content

[0006] The cam is secured to the upper and lower ends of the cam, and the cam is secured to the lower ends of the cam, and the cam is secured to the lower ends of the cam.
[0007] Preferably, a drainage air channel communicating with the air flow ring groove is provided inside the sealing cover and the extension ring plate.
[0008] Preferably, the hydraulic tank is a giant structure with a C-shaped connecting tank body opened inside.

[0011] Preferably, an external buckle or strap assembly is required between the cover and the box body for auxiliary fixation.
[0012] Beneficial effects
[0013] The utility model provides a compartmentalized self-circulating cold chain transport box. Compared with the existing technology, it has the following advantages:
[0014] (1) The chambered self-circulating cold chain transport box has a box body, an air flow ring groove, an air pump, a sealing cover, an extension ring plate, a drainage air duct, a storage tank, and a second pressure relief valve. This circulating refrigeration method can make the temperature inside the box body more uniform. The circulating airflow formed by the air pump and the drainage air duct can quickly diffuse the cold air generated in the refrigeration area to the upper space inside the entire box body and the inside of the storage tank, thereby promoting the circulation of cold air. While ensuring the full utilization of the cold air, it avoids the situation where the local temperature is too low or too high, thereby better protecting the quality of the transported items.
[0015] (2) The chambered self-circulating cold chain transport box can discharge the melted liquid after heat exchange downward through the arrangement of the box body, hydraulic tank, first pressure relief valve, spring rod and piston plate, and store it in a designated sealed space. It cooperates with the hydraulic tank and piston plate to form a hydraulic state, and when subjected to bumps and vibrations, it cooperates with the spring rod to timely buffer and reduce the vibrations. At the same time, when the capacity of the spring rod and hydraulic shock absorption is exceeded, the first pressure relief valve can be used to relieve pressure to reduce the vibrations, thereby reducing the impact of bumpy sections on the transport box.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-3A chambered self-circulating cold chain transport box includes a transport structure 1, which includes a box body 11. An upwardly extending air flow ring groove 111 is provided in an annular manner along the box board path at the middle and upper position of the box board inside the box body 11. The left and right inner walls of the box body 11 are provided with communicating air holes at the positions corresponding to the air flow ring grooves 111, and an air pump 112 is fixedly provided at the input port of the air hole. The air pump 112 is electrically connected to the electric control power module inside the box body 11. The box body 11 is in the air flow ring groove 111. An extension ring plate 121 of the cover 12 is inserted at the upper port, and the extension ring plate 121 is integrally arranged at the bottom of the cover 12, and a drainage air duct 122 connected to the air flow ring groove 111 is opened inside the cover 12 and the extension ring plate 121. A handle for lifting is integrally provided at the center position of the upper surface of the cover 12. An external auxiliary fixing buckle or strap assembly is required between the cover 12 and the box body 11. The upper part of the box body 11 is positioned with a storage tank through the ring edge of the upper port of the storage tank 13. 13. A plurality of through mounting holes are provided at the bottom of the material storage trough 13, and a second pressure relief valve 131 is threadedly connected through the mounting holes. A hydraulic groove 114 is integrally provided at the bottom of the box body 11, and a mounting hole for connecting the box body 11 and the hydraulic groove 114 is provided in the front-to-back direction at the center position of the surface of the box plate separating the box body 11 and the hydraulic groove 114, and a check valve 113 is installed inside the mounting hole. The hydraulic groove 114 is a giant structure, and a C-shaped connecting groove body is provided inside it, and at least one mounting through hole is provided on the surface of the left and right side wall plates, and a first pressure relief valve 1141 is installed inside the mounting through hole. A plurality of freely retractable spring rods 1142 are fixed on the bottom surface of the central partition of the hydraulic groove 114, and the lower ends of the spring rods 1142 are fixed to the surface of the piston plate 14. The piston plate 14 consists of a plate body and two piston columns, wherein sliding rods for assisting the lifting of the piston plate 14 are integrally provided at the four corners of the plate body, and the piston seal slides inside the hydraulic groove 114.
[0022] During operation, the air pump 112 is started to pump gas (such as air) into the gas flow ring groove 111. The gas flows along the gas flow ring groove 111 and enters the interior of the storage tank 13 through the drainage air channel 122. As the air pressure inside the storage tank 13 increases, it will break through the threshold of the second pressure relief valve 131 and then flow back into the interior of the box body 11 through the second pressure relief valve 131. In this process, as the storage tank 13 and the interior of the box body 11 continue to exchange heat, the refrigerant inside the box body 11 will gradually absorb heat and melt, and the melted water will accumulate inside the box body 11 and break through the stop valve 131. The threshold of the reverse valve 113 flows into the space isolated from the hydraulic groove 114 and the piston plate 14. When the car travels on a bumpy road section, the box body 11 and the parts it carries will move downward under its own weight, and in the process of moving downward, the liquid stored between the hydraulic groove 114 and the piston plate 14 will be compressed. At the same time, the spring rod 1142 will be compressed. If the amplitude of the bump is large or the box body 11 and the parts it carries move downward too much due to their own weight, the liquid between the hydraulic groove 114 and the piston plate 14 will be compressed to discharge through the first pressure relief valve 1141, thereby achieving the effect of hydraulic shock absorption of the box body 11.
[0023] In summary, through the arrangement of the box body 11, the air flow ring groove 111, the air pump 112, the cover 12, the extension ring plate 121, the drainage air duct 122, the storage tank 13, and the second pressure relief valve 131, this circulating refrigeration method can make the temperature inside the box body 11 more uniform, and the circulating airflow formed by the air pump 112 and the drainage air duct 122 can quickly diffuse the cold air generated in the refrigeration area to the upper space inside the entire box body 11 to the inside of the storage tank 13, thereby promoting the circulation of cold air. While ensuring full utilization of the cold air, it avoids the situation where the local temperature is too low or too high, thereby better The quality of the transported items is protected; through the arrangement of the box body 11, the hydraulic groove 114, the first pressure relief valve 1141, the spring rod 1142 and the piston plate 14, the melted liquid after heat exchange can be discharged downward and stored in a designated sealed space, and cooperate with the hydraulic groove 114 and the piston plate 14 to form a hydraulic state, and when subjected to bumpy vibration, cooperate with the spring rod 1142 to buffer and reduce the vibration in time. At the same time, when the capacity of the spring rod 1142 and the hydraulic shock absorption capacity is exceeded, the first pressure relief valve 1141 can also be used to relieve pressure to reduce the vibration, thereby reducing the impact of bumpy roads on the transport box.
[0024] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.
[0025] Working principle: When working, first, place the refrigeration material (such as ice cubes, etc.) at the bottom of the box body 11, then place the storage tank 13, so that the storage tank 13 is positioned above the inside of the box body 11, and place the items to be transported inside the storage tank 13, and then cover the cover 12, ensuring that the cover 12 is tightly fixed to the box body 11 through the external buckle or strap assembly, and the extension ring plate 121 is accurately inserted into the inside of the air flow ring groove 111, so that the drainage air duct inside the cover 12 and the extension ring plate 121 122 is connected to the gas ring groove 111, and then the initial state of each component is checked, including the air pump 112, the check valve 113, the first pressure relief valve 1141, the second pressure relief valve 131, etc., to ensure that they are in a normal working state, the piston plate 14 is in the initial position in the hydraulic groove 114, and the spring rod 1142 is in a natural expansion state. Then it can be transported to the transport vehicle for transportation. During transportation, the air pump 112 is started to pump gas (such as air) into the gas ring groove 111, and the gas moves along the gas ring groove 111. The liquid flows through the tank 111 and enters the interior of the storage tank 13 through the drainage air channel 122. As the pressure inside the storage tank 13 increases, it will break through the threshold of the second pressure relief valve 131 and then flow back into the interior of the box 11 through the second pressure relief valve 131. In this process, as the storage tank 13 and the interior of the box 11 continue to exchange heat, the refrigerant inside the box 11 will gradually absorb heat and melt. The melted water will accumulate inside the box 11 and break through the threshold of the check valve 113 to flow into the hydraulic tank 114 and the piston. In the space isolated by the plate 14, when the car travels on a bumpy road section, the box body 11 and the parts it carries will move downward under their own weight, and in the process of moving downward, the liquid stored between the hydraulic groove 114 and the piston plate 14 will be compressed. At the same time, the spring rod 1142 will be compressed. If the amplitude of the bumps is large or the box body 11 and the parts it carries move downward too much due to their own weight, the liquid between the hydraulic groove 114 and the piston plate 14 will be compressed to discharge through the first pressure relief valve 1141, thereby achieving the effect of hydraulic shock absorption of the box body 11.
