Description

An energy-saving and environmentally friendly cold chain logistics equipment Technical Field

[0001] The present invention belongs to the technical field of cold chain logistics, and specifically relates to energy-saving and environmentally friendly cold chain logistics equipment. Background Art

[0002] With the rapid development of the cold chain logistics industry, energy-saving and environmentally friendly cold chain distribution equipment has gradually become a research hotspot in the logistics field due to its advantages in reducing resource waste and environmental pollution. However, existing cold chain logistics equipment has certain limitations in terms of thermal insulation performance, energy efficiency, and intelligent control, which has affected its practical application and promotion.

[0003] After searching, a simple cold chain logistics distribution equipment with the publication number CN106938742B was found, and the publication date was February 12, 2019. This patent solves the problem of supercooling demand in short-distance transportation by filling a refrigerant made of water and food-grade sodium polyacrylate between the outer shell and the inner liner of the insulation box, and combining it with a temperature-sensitive color-changing optical film to achieve temperature monitoring, while also having the characteristics of environmental protection and energy saving. However, in this technical solution, the cold release and thermal insulation performance of the refrigerant are greatly affected by the external ambient temperature, and there is room for improvement in the temperature control accuracy, which may cause temperature fluctuations in cold chain items during transportation, thereby having a certain impact on the quality of the items. In addition, the temperature-sensitive color-changing optical film can only provide visual cues of temperature changes, lacks real-time data recording and remote monitoring functions, and is difficult to meet the needs of modern logistics for informatization and intelligence. Technical issues

[0004] The above issues indicate that existing cold chain logistics equipment still has room for improvement in terms of temperature control accuracy, cold release stability, and intelligent management. Therefore, the present invention provides energy-saving and environmentally friendly cold chain logistics equipment that optimizes the cold release mechanism, improves the accuracy and stability of temperature control, and introduces an intelligent monitoring system to meet the demand for efficient, intelligent, and green cold chain equipment in modern logistics. Technical Solutions

[0005] The purpose of the present invention is to provide an energy-saving and environmentally friendly cold chain logistics equipment to solve the problems raised in the prior art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: the cold chain logistics equipment includes an insulation cabin, a cold capacity control cabin, a data acquisition cabin, a cold storage module, a temperature detection unit and a conveying pipeline. The insulation cabin, the cold capacity control cabin and the data acquisition cabin are arranged in sequence along the direction of the cold air flow. The cold storage module is fastened to the outer wall of the insulation cabin by bolts. The cold storage module is connected to the conveying pipeline. One end of the conveying pipeline is fastened to the insulation cabin. The conveying pipeline is used to convey the cold air flow. The temperature detection unit is connected to the conveying pipeline. The temperature detection unit is used to detect temperature fluctuations in the cold air flow.

[0007] This application is used to deal with the temperature control problem during cold chain transportation. The cold air flow to be processed first passes through the insulation cabin for preliminary temperature control to remove heat fluctuations in the cold air flow. The conveying pipeline then conveys the processed cold air flow to the cold capacity control cabin for precise control, so that the temperature of the cold air flow is maintained within the set range. The processed cold air flow finally flows into the data acquisition cabin for real-time recording, thereby ensuring the temperature stability of cold chain items; when the conveying pipeline conveys the cold air flow, the temperature fluctuations of the cold air flow during the conveying process are monitored in real time through the temperature detection unit, and the cold capacity released from the cold storage module is adjusted in real time according to the temperature changes of the cold air flow, thereby optimizing the temperature stability of the cold air flow.

[0008] Furthermore, an air inlet and a heat insulation layer are provided on one side of the heat insulation cabin. The heat insulation layer is connected to the inner wall of the heat insulation cabin by a snap fastener. The heat insulation layer is arranged in several layers, and the thickness of the several heat insulation layers gradually increases.

[0009] The cold air flows into the insulation cabin through the air inlet, and the heat fluctuations in the cold air flow are isolated by several insulation layers. Several insulation layers of different thicknesses realize multi-level insulation of the cold air flow, thereby improving the insulation effect. The insulation layer connected to the insulation cabin by buckles is easy to disassemble and replace.

[0010] Furthermore, the delivery pipeline includes a fan and a guide pipe, the fan is tightly connected to the insulation cabin, the air outlet of the fan is connected to the guide pipe, the air outlet of the guide pipe is connected to the cooling control cabin, and an adjustment component is provided on the guide pipe, which is used to control the amount of cooling release. The cold storage module has a built-in refrigeration pump, and a cooling delivery pipe is provided at the output end of the refrigeration pump, which is connected to the adjustment component.

[0011] The fan at the bottom of the insulation cabin can transport the cold air flow after preliminary temperature control to the cooling control cabin for processing. The guide pipe is used to provide guidance for the cold air flow. The refrigeration pump in the cold storage module pumps the cold air into the guide pipe at a certain flow rate, thereby mixing it with the cold air flow in the guide pipe. The adjustment component on the guide pipe can adjust the amount of cold release flowing from the cold delivery pipe into the guide pipe in real time according to the temperature fluctuations measured by the temperature detection unit, thereby realizing real-time adjustment of the cold release amount.

[0012] Furthermore, the temperature detection unit includes a spiral channel, a detection chamber, a diverter plate and a sensing component. The air inlet end of the spiral channel is connected to the guide pipe, the air outlet end of the spiral channel is connected to the detection chamber, the air outlet end of the detection chamber is connected to the cooling control cabin, the diverter plate and the sensing component are located in the detection chamber, the sensing component is used to detect temperature fluctuations in the cold air flow, a cooling pipeline is wound around the outside of the spiral channel, and the cooling pipeline is connected to an external low-temperature source.

[0013] Since the flow of cold air flow is a continuous process, and the temperature distribution in the cold air flow is uneven, this will cause the temperature fluctuations in the cold air flow passing through the guide tube to change, and the temperature will rise or fall within a period of time; since the gas temperature changes with the changes in the external environment, a cooling pipeline is wound around the outside of the spiral channel to cool the cold air flow passing through the spiral channel to a certain temperature. As the temperature decreases, excess heat will be separated from the cold air flow in the form of thermal radiation, and the greater the temperature fluctuation in the cold air flow, the more heat will be separated, and under the guidance of the spiral channel, it will perform spiral motion. Under the action of centrifugal force, the heat molecules with heavier weight will be distributed on the outer circle of the spiral channel, and the cold air flow passing through the detection cavity will be divided into two parts by the diverter plate. The cold air flow containing heat separations flows to the sensing component under the guidance of the diverter plate. The sensing component can determine the temperature fluctuations in the cold air flow by detecting the amount of heat separations.

[0014] Furthermore, a slide rail and a sensing groove are provided on one side of the detection chamber close to the outer ring of the spiral channel, the diverter plate is tightly connected to the detection chamber, the diverter plate is located in the middle of the flow channel of the detection chamber, the sensing assembly includes a pressure plate, a sliding block, a magnetic rod and a reset spring, the pressure plate is slidingly connected to the inner wall of the detection chamber, the pressure plate is tightly connected to the sliding block, the sliding block is slidingly connected to the slide rail, the magnetic rod is tightly connected to the sliding block, one end of the reset spring is tightly connected to the sliding block, the other end of the reset spring is tightly connected to the inner wall of the slide rail, a coil is wound around the outside of the sensing groove, the sensing groove is connected to the slide rail, and the coil is externally connected to a power supply;

[0015] During detection: insert the magnetic rod into the sensing slot.

[0016] Since the greater the temperature fluctuation in the cold air flow, the more heat is separated during cooling, and when the cold air flow containing heat separations hits the pressure plate at a certain flow rate under the guidance of the diverter plate, the greater the heat content in the cold air flow, the greater the impact force on the pressure plate; under the action of the impact force, the pressure plate will drive the sliding block to one side along the slide rail, the return spring will be stretched, the magnetic rod will be inserted into the induction slot, and the coil will move by cutting the magnetic lines of force, thereby generating an induced current, and the more heat there is in the cold air flow, the greater the impact force on the pressure plate, the longer the distance the magnetic rod is inserted into the induction slot, and the greater the induced current generated, that is, the greater the induced current generated by the coil, the greater the temperature fluctuation in the cold air flow, thereby realizing real-time detection of temperature fluctuations in the cold air flow.

[0017] Furthermore, the diverter plate is arc-shaped, and the windward surface of the pressure plate is arranged at an inclination.

[0018] The arc-shaped splitter plate can reduce resistance, and the inclined pressure plate can guide the cold air flow to prevent the heat separated from the cold air flow from accumulating on the pressure plate.

[0019] Furthermore, the diameter of the spiral channel gradually decreases.

[0020] Because the cold air flow flows through the spiral channel at a certain flow rate, the centrifugal force on the cold air flow is increased by providing a spiral channel with a gradually decreasing diameter, thereby improving the separation effect of separating heat from the cold air flow.

[0021] Furthermore, the adjustment assembly includes a fixed sleeve, a movable sleeve, a drive motor and a transmission gear. The fixed sleeve is tightly connected to the guide tube, an annular channel and a power chamber are provided in the fixed sleeve, the movable sleeve is rotatably connected to the fixed sleeve, a flow hole and a rack are provided on the movable sleeve, a cooling release hole is provided on the guide tube, the drive motor is tightly connected to the fixed sleeve, the output end of the drive motor is in transmission connection with the transmission gear, the transmission gear is located in the power chamber, and the transmission gear is meshed with the rack;

[0022] When releasing cold energy: the circulation hole is connected with the cold energy release hole.

[0023] In the initial state, the circulation holes and the cold release holes are arranged in an alternating manner, and the drive motor is the main power source of the adjustment component. When releasing cold air, the larger the overlapping area of ​​the circulation holes and the cold release holes, the larger the flow cross-section formed, and the more cold air released; when the temperature detection unit detects that the temperature fluctuation in the cold air flow increases, the drive motor starts and drives the transmission gear to rotate, thereby transmitting power to the rack engaged with it, so that the movable sleeve rotates a certain angle along the fixed sleeve, thereby increasing the overlapping area of ​​the circulation holes and the cold release holes, and increasing the amount of cold air released into the guide tube, thereby realizing automatic adjustment of the released cold air according to the real-time temperature fluctuation in the cold air flow.

[0024] Furthermore, an overflow port is provided on a side of the cooling control cabin close to the data acquisition cabin, a data outlet is provided on an upper side of the data acquisition cabin, and a heat exhaust port is provided on a lower side of the data acquisition cabin.

[0025] The cold air flow processed by the cooling control cabin flows into the data acquisition cabin through the overflow port, where it is further analyzed. The heat molecules gradually settle to the bottom of the data acquisition cabin and flow out from the heat exhaust port at the bottom, while the stable cold air flow is discharged from the data outlet.

[0026] Furthermore, a stirring device is provided in the cooling control cabin, the stirring device includes a driving motor and a rotating shaft, the driving motor is firmly connected to the cooling control cabin, the output end of the driving motor is transmission-connected to the rotating shaft, and a plurality of stirring blades are provided on the rotating shaft.

[0027] In order to promote the mixing of cold energy and cold air flow, a corresponding stirring device is set in the cold energy control cabin. During stirring, the driving motor outputs torque to drive the rotating shaft to rotate, and then drives the stirring blades to rotate in the cold energy control cabin, thereby promoting the uniform mixing of cold energy and cold air flow.

Best Mode for Carrying Out the Invention

[0039] The present invention provides a structure as shown in Figure 1, including an insulation cabin 1, a cold capacity control cabin 2, a data acquisition cabin 3, a cold storage module 4, a conveying pipeline 5 and a temperature detection unit 6. These components form a complete cold chain transportation temperature control system through a specific connection relationship and position arrangement. The insulation cabin 1 is located at the front end of the flow direction of the cold air flow, and an air inlet 7 is provided on one side thereof, and the air inlet 7 is used to introduce the cold air flow to be processed. The inner wall of the insulation cabin 1 is connected with a multi-layer insulation layer 8 by a snap fastener, and the thickness of the insulation layer 8 gradually increases along the flow direction of the cold air flow, thereby achieving a multi-stage insulation effect on the cold air flow. The outer wall of the insulation cabin 1 is fastened to the cold storage module 4 by bolts, and the cold storage module 4 has a built-in refrigeration pump. The output end of the refrigeration pump is connected to the adjustment component 11 in the conveying pipeline 5 through a cold capacity delivery pipe to achieve accurate release of cold capacity.

[0040] The delivery duct 5 includes a fan 9 and a flow guide duct 10. The fan 9 is fixedly mounted on the bottom of the insulation chamber 1 and securely connected to the chamber via a flange. The air outlet of the fan 9 communicates with one end of the flow guide duct 10, while the other end of the flow guide duct 10 communicates with the cooling control chamber 2. The flow guide duct 10 is equipped with an adjustment assembly 11. The detailed structure of the adjustment assembly 11 is shown in Figure 6 and includes a fixed sleeve 24, a movable sleeve 25, a drive motor 26, and a transmission gear 27. The fixed sleeve 24 is welded to the flow guide duct 10. An annular channel and a power chamber are defined within the fixed sleeve 24. The movable sleeve 25 is rotatably connected to the fixed sleeve 24 via a bearing. A flow hole 28 is defined in the movable sleeve 25, and a corresponding cooling release hole 29 is provided on the flow guide duct 10. The drive motor 26 is bolted to the outer wall of the fixed sleeve 24. The output end of the drive motor 26 is connected to the transmission gear 27 via a coupling. The transmission gear 27 is located within the power chamber and meshes with the rack on the movable sleeve 25. When the cold energy needs to be released, the driving motor 26 drives the transmission gear 27 to rotate, thereby driving the movable sleeve 25 to rotate, so that the overlapping area of ​​the circulation hole 28 and the cold energy release hole 29 increases or decreases, thereby adjusting the amount of cold energy released.

[0041] The temperature detection unit 6 is connected to the conveying pipe 5, and its specific structure is shown in Figures 4 and 5, including a spiral channel 12, a detection chamber 13, a diverter plate 14 and a sensing component 15. The air inlet end of the spiral channel 12 is connected to the guide tube 10, and the air outlet end is connected to the detection chamber 13. The diameter of the spiral channel 12 gradually decreases along the flow direction of the cold air flow to enhance the centrifugal force of the cold air flow, thereby improving the separation effect of the heat separation. A cooling pipeline 16 is wound around the outside of the spiral channel 12, and the cooling pipeline 16 is externally connected to a low-temperature source for cooling the cold air flow to a certain temperature. A slide rail 17 and an induction groove 18 are provided on the side of the detection chamber 13 close to the outer circle of the spiral channel 12. The diverter plate 14 is fastened to the detection chamber 13 by bolts and is located in the middle of the flow channel of the detection chamber 13. The induction assembly 15 includes a pressure plate 19, a sliding block 20, a magnetic rod 21, and a return spring 22. The pressure plate 19 is slidably connected to the inner wall of the detection chamber 13 via a slide groove. The windward side of the pressure plate 19 is tilted to reduce resistance and prevent heat accumulation. The pressure plate 19 is fastened to the sliding block 20 via bolts. The sliding block 20 is slidably connected to the detection chamber 13 via the slide rail 17. The magnetic rod 21 is fastened to the sliding block 20 via threads. One end of the return spring 22 is fastened to the sliding block 20 via a screw, and the other end is fastened to the inner wall of the slide rail 17 via a screw. A coil 23 is wound around the outside of the induction slot 18. The coil 23 is connected to an external power supply. The induction slot 18 is connected to the slide rail 17 through an opening. When the cold air flow passes through the spiral channel 12, the heat separation therein is distributed to the outer ring of the spiral channel 12 under the action of centrifugal force, and impacts the pressure plate 19 under the guidance of the diverter plate 14. The pressure plate 19 drives the sliding block 20 to move along the slide rail 17, the return spring 22 is stretched under the force, the magnetic rod 21 is inserted into the induction slot 18, and the coil 23 cuts the magnetic lines of force to generate an induced current. The magnitude of the induced current is proportional to the temperature fluctuation in the cold air flow, thereby realizing real-time detection of the temperature fluctuation of the cold air flow.

[0042] An overflow port 30 is provided on the side of the cooling control cabin 2 near the data acquisition cabin 3. A stirring device 33 is installed within the cooling control cabin 2. The stirring device 33 comprises a drive motor 26, a rotating shaft 34, and stirring blades 35. The drive motor 26 is bolted to the top of the cooling control cabin 2. The output end of the drive motor 26 is connected to the rotating shaft 34 via a coupling. Several stirring blades 35 are evenly distributed on the rotating shaft 34. Driven by the drive motor 26, the stirring blades 35 rotate, promoting the uniform mixing of the cooling energy and the cold airflow, thereby improving the accuracy of temperature control. The cold airflow processed by the cooling control cabin 2 flows through the overflow port 30 into the data acquisition cabin 3. The data acquisition cabin 3 has a data outlet 31 on one side at the top and a heat exhaust port 32 on the lower side. After further analysis within the data acquisition cabin 3, the stable cold airflow is discharged through the data outlet 31, while the heat molecules settle to the bottom and are discharged through the heat exhaust port 32.

[0043] The working process of this cold chain logistics equipment is as follows: the cold air flow first enters the insulation cabin 1 through the air inlet 7, and the heat fluctuation is removed by the insulating effect of the multi-layer insulation layer 8. The cold air flow after preliminary temperature control is transported to the guide pipe 10 by the fan 9. In the guide pipe 10, the cold air flow is mixed with the cold energy released from the cold storage module 4, and the regulating component 11 adjusts the cold energy release amount in real time according to the temperature fluctuation measured by the temperature detection unit 6 to ensure that the temperature of the cold air flow is maintained within the set range. Subsequently, the cold air flow enters the cold energy regulation cabin 2, and is further mixed evenly under the action of the stirring device 33, and finally flows into the data acquisition cabin 3 through the overflow port 30 for real-time recording and analysis. The processed cold air flow is discharged from the data outlet 31, and the separated heat is discharged from the heat exhaust port 32, thereby achieving stable temperature control during the cold chain transportation process.

[0044] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is further supplemented below in combination with a specific application scenario.

[0045] During cold chain transportation, cold chain logistics equipment must ensure the temperature stability of cold chain items throughout the entire transportation process. Taking pharmaceutical cold chain transportation as an example, vaccines and other biological products are extremely sensitive to temperature fluctuations, necessitating precise temperature control of the transportation environment. The following describes this technology in detail, combining the structural design and operating principles of the present invention.

[0046] First, the cold air flows into the insulation chamber 1 through the air inlet 7. Because the inner wall of the insulation chamber 1 is provided with multiple layers of insulation 8, and the thickness of the insulation layer 8 gradually increases along the flow direction of the cold airflow, the cold airflow is gradually isolated from the influence of external heat fluctuations as it passes through the insulation layer 8. This multi-stage insulation design can effectively reduce the interference of external ambient temperature changes on the cold airflow, thereby initially stabilizing the temperature of the cold airflow. For example, when the external temperature is high, the gradually increasing thickness of the insulation layer 8 can significantly slow the heat transfer rate, reduce the temperature rise of the cold airflow, and lay the foundation for subsequent precise control.

[0047] Subsequently, the cold air flow that has undergone preliminary temperature control is transported to the guide tube 10 by the fan 9. During this process, the refrigeration pump in the cold storage module 4 releases the cold energy into the guide tube 10 through the cold energy delivery pipe. The regulating component 11 adjusts the amount of cold energy released according to the real-time feedback of the temperature detection unit 6. Specifically, when the temperature detection unit 6 detects that the temperature fluctuation of the cold air flow is large, the drive motor 26 starts, drives the transmission gear 27 to rotate, and then drives the movable sleeve 25 to rotate, so that the overlapping area between the circulation hole 28 and the cold energy release hole 29 increases, thereby increasing the amount of cold energy released. Conversely, when the temperature of the cold air flow tends to be stable, the drive motor 26 rotates in the opposite direction, reducing the overlapping area between the circulation hole 28 and the cold energy release hole 29, and reducing the amount of cold energy released. This dynamic adjustment mechanism can ensure that the temperature of the cold air flow is always maintained within the set range, meeting the temperature accuracy requirements of cold chain transportation.

[0048] Then, the cold air flow enters the cold energy control cabin 2. Inside the cold energy control cabin 2, the stirring device 33 starts working, the driving motor 26 outputs torque, drives the rotating shaft 34 to rotate, and then drives the stirring blades 35 to evenly mix the cold air flow and the cold energy. The rotation of the stirring blades 35 allows the cold air flow to fully contact the cold energy, avoiding the occurrence of local temperatures that are too high or too low. For example, in an area where the cold air flow temperature is lower, the stirring blades 35 can guide the cold energy to an area with a higher temperature, thereby achieving overall temperature uniformity. The cold air flow after sufficient mixing flows into the data acquisition cabin 3 through the overflow port 30.

[0049] Inside data acquisition cabin 3, the cold airflow is further analyzed and processed. A stable cold airflow is discharged from data outlet 31, while the separated heat molecules settle to the bottom and are discharged through heat exhaust vent 32. This process ensures high temperature stability of the cold airflow as it exits data acquisition cabin 3, while also preventing heat accumulation from impacting system performance. For example, during long-term transportation, data acquisition cabin 3 can continuously monitor the status of the cold airflow and promptly remove excess heat through heat exhaust vent 32, preventing heat backflow from affecting the temperature control effect of the cold airflow.

[0050] In addition, the temperature detection unit 6 plays a key role in the entire process. When the cold air flow passes through the spiral channel 12, the cooling pipeline 16 wrapped around its outside cools the cold air flow to a certain temperature, and the excess heat is separated in the form of thermal radiation and distributed to the outer ring of the spiral channel 12 under the action of centrifugal force. The diverter plate 14 guides the cold air flow containing heat separation to the sensing component 15, wherein the pressure plate 19 drives the sliding block 20 to move along the slide rail 17 after being impacted, and the magnetic rod 21 is inserted into the sensing slot 18, and the coil 23 cuts the magnetic flux lines to generate an induced current. The magnitude of the induced current is proportional to the temperature fluctuation in the cold air flow, thereby realizing real-time detection of the temperature fluctuation of the cold air flow. This detection method is not only highly sensitive, but also can quickly respond to temperature changes, providing accurate feedback signals for the adjustment component 11.

[0051] In summary, this invention addresses the shortcomings of existing cold chain logistics equipment in temperature control accuracy, cold release stability, and intelligent management through a variety of technical means, including multi-stage insulation, dynamic cold capacity adjustment, mixing, and real-time temperature detection. In practical applications, this equipment can significantly improve the efficiency and reliability of cold chain transportation, and is particularly suitable for applications in the pharmaceutical and fresh produce sectors, which have strict temperature requirements.
