Description

Technical Field

[0001] This application relates to the technical field of cold chain transportation, and in particular to an intelligent equalization refrigeration device for cold chain transportation. Background Technology

[0002] Cold chain transportation refers to the transportation of goods at a constant temperature throughout the entire process, including loading and unloading, changing transportation methods, and replacing packaging equipment. Cold chain transportation can be carried out by road, water, rail, or air, or it can be a combination of multiple modes of transportation. Cold chain transportation is an important link in cold chain logistics. It is costly and involves complex mobile refrigeration technology and insulated box manufacturing technology. Cold chain transportation management involves more risks and uncertainties.

[0003] In cold chain transportation, goods are typically transported by road in refrigerated trucks. During transport, refrigeration units lower the temperature inside the cargo compartment to cool the goods. However, existing cold chain transport vehicles only have a single air outlet inside the cargo compartment for cooling. The refrigeration unit is usually installed near the front of the vehicle. Furthermore, cold chain transport cargo compartments are often quite long. When the cargo compartment is full, there is a significant temperature difference between the area near the refrigeration unit's outlet and the rear of the compartment. Cold air tends to accumulate at the bottom of the compartment, resulting in uneven temperature distribution and affecting the cooling effect. Utility Model Content

[0004] In order to improve the refrigeration effect of refrigerated trucks and ensure that the temperature is uniform throughout the cargo compartment, this application provides an intelligent balanced refrigeration device for cold chain transportation.

[0005] This application provides an intelligent balanced refrigeration device for cold chain transportation, which adopts the following technical solution:

[0006] A smart balanced refrigeration device for cold chain transportation includes a cargo compartment, a refrigeration unit installed outside the cargo compartment to deliver cold air into the cargo compartment, an automatic control unit installed on the cargo compartment to control the refrigeration unit, and a cold air flow device installed inside the cargo compartment near the rear. The end of the cargo compartment away from the refrigeration unit is hinged to a door for easy loading. The automatic control unit can automatically monitor the temperature at various points inside the cargo compartment and control the automatic start and stop of the refrigeration unit. The refrigeration unit is installed at the end of the cargo compartment near the front of the vehicle and located near the upper side of the cargo compartment. The cold air flow device includes a cross-flow fan installed inside the cargo compartment. The cross-flow fan is provided with an air inlet and an air outlet. The cross-flow fan is installed on the lower side of the cargo compartment near the door, and the cross-flow fan and the refrigeration unit are arranged diagonally upwards and downwards. The air inlet of the cross-flow fan is horizontally arranged facing the front of the cargo compartment, and its air outlet is vertically upwards.

[0007] By adopting the above technical solution, the automatic control device can automatically control the start and stop of the refrigeration equipment according to the temperature inside the cargo compartment, thereby ensuring that the cargo compartment is always at a suitable transportation temperature. The cross-flow fan installed in the cargo compartment can form an oblique design with the refrigeration equipment in space. The cold air output by the refrigeration equipment can accumulate at the bottom of the cargo compartment. Under the action of the cross-flow fan, the cold air at the bottom of the cargo compartment can be transported to the top of the cargo compartment, indirectly allowing the cold air in the cargo compartment to circulate from bottom to top, thereby keeping the various temperatures in the cargo compartment consistent and improving the refrigeration effect of the cargo compartment.

[0008] Preferably, a pair of air guide blocks are provided on the inner wall of the cargo compartment. The two air guide blocks are respectively positioned above the cross-flow fan and below the refrigeration equipment. The air guide blocks are arranged along the width direction of the cargo compartment and have an arc-shaped air guiding surface, which can change the air from a vertical state to a horizontal state. The air outlet of the refrigeration equipment is aligned with the air guide block below it.

[0009] By adopting the above technical solution, during the process of the refrigeration equipment and cross-flow fan circulating cold air up and down, the cold air output by the refrigeration equipment can be blown onto the air guide block, so that the cold air blows towards the cross-flow fan, and after being guided by the cross-flow fan, it is blown towards another air guide block, and the flow direction of the cold air is changed again. Finally, the cold air can form a circular circulation flow in the cargo compartment through the two air guide blocks, so that the cold air can circulate to every place in the cargo compartment and keep the cargo compartment in a constant state.

[0010] Preferably, the cargo compartment is provided with a partition device to divide the storage area inside the cargo compartment. The partition device includes a partition plate installed inside the cargo compartment and arranged along the cross-section of the cargo compartment. The partition plate can divide the interior of the cargo compartment into a storage area for storing goods and a blank area. The storage area is located near the refrigeration equipment. The cross-flow fan and its corresponding air guide block are both installed on the partition plate.

[0011] By adopting the above technical solution, when the goods to be transported cannot fill the cargo compartment, the partition is installed inside the cargo compartment, so that the interior is divided into a storage area for stacking goods and a blank area. During the refrigeration process, the cold air circulates only in the storage area for storing goods, reducing the waste of cold air.

[0012] Preferably, the partition plate is slidably fitted inside the cargo compartment and slides along the length of the cargo compartment.

[0013] By adopting the above technical solution, the partitions that slide inside the cargo compartment can be adjusted more easily by the staff, avoiding the need to move the partitions back and forth.

[0014] Preferably, the partition device includes a control component disposed inside the cargo compartment and used to control the sliding of the partition plate. The control component is disposed inside the cargo compartment and near its top. The control component includes a control motor fixed inside the cargo compartment and near the end of the refrigeration equipment and a pair of control components connected to the partition plate. The two control components are symmetrically disposed on the two side walls inside the cargo compartment. The control motor operates the control components to rotate.

[0015] By adopting the above technical solution and using electrically controlled partitions, the partitions can be automatically moved closer to the goods according to the amount of goods loaded, avoiding the need for manual sliding of the partitions and improving work efficiency.

[0016] Preferably, the control components include a pair of synchronous pulleys rotatably mounted on the inner wall of the cargo compartment and a toothed belt fitted onto the two synchronous pulleys. The two synchronous pulleys are symmetrically arranged near both ends of the cargo compartment. The partition plate is connected and fixed to one side of the synchronous pulleys. A synchronous shaft is connected and fixed between the corresponding two synchronous pulleys on both sets of control components. The control motor controls the rotation of one of the synchronous shafts.

[0017] By adopting the above technical solution, the motor drives the synchronous shaft to rotate, and controls the rotation of two synchronous pulleys located at the same end. Then, the toothed belt is controlled to rotate in a ring, allowing the partition plate to move horizontally. This is more convenient and faster to implement. Furthermore, the synchronous pulleys and toothed belts will not slip. In addition, the synchronous pulleys and toothed belts are cheaper to use, making it more economical to retrofit existing refrigerated trucks.

[0018] Preferably, the partition consists of two pieces of the same size, which can be spliced ​​and assembled into the interior of the cargo compartment.

[0019] By adopting the above technical solution, the partition plate is composed of two parts, which allows for better control over its movement.

[0020] Preferably, the separating device further includes a separating component, which includes a U-shaped separating frame that is slidably disposed inside the cargo compartment, with two separating plates hinged on the separating frame, and the separating frame being connected and fixed to one side of the toothed belt.

[0021] By adopting the above technical solution, the partition frame can serve as a mounting base, allowing the partition plate to be hinged on the partition frame. During the loading process, the partition plate can be rotated to open the loading opening for normal loading. After loading is completed, it can be rotated to close immediately. In addition, the partition frame can remain stable during the sliding of the partition plate, preventing the partition plate from tilting and moving into the cargo compartment.

[0022] Preferably, the partition assembly further includes a pair of guide rods fixed to the inner wall of the cargo compartment. The two guide rods are arranged along the length of the cargo compartment, and the partition frame is provided with a sliding groove. The guide rods and the sliding groove are slidably engaged.

[0023] By adopting the above technical solution, the guide rod and the slide groove slide together, allowing the partition frame to slide along the direction of the guide rod and ensuring that the partition frame is more stable during the sliding process.

[0024] Preferably, the partition assembly further includes a reset component disposed on the partition frame and keeping the partition plate in a closed state at all times. The reset component includes a guide ring fixed on the partition frame and located on one side of the hinge point. The guide ring passes through the partition plate, allowing the partition plate to rotate along the circular direction of the guide ring. A pair of reset springs are sleeved on the guide ring. The two reset springs are symmetrically disposed on both sides of the partition plate, and the two ends of the reset springs abut against the partition frame and the partition plate.

[0025] By adopting the above technical solution, the two partitions can always be kept closed under the action of the reset component, thereby keeping the storage area in a closed environment and preventing the leakage of cold air inside; during the loading process, the partitions are fixed to the inner wall of the cargo compartment, and after loading is completed, the partitions are automatically closed.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. With the help of refrigeration equipment, cross-flow fans and two air guide blocks, the cold air can circulate inside the cargo compartment, so that the cold air fills every part of the cargo compartment;

[0028] 2. The partition divides the interior of the cargo compartment into two parts, which can be used when the cargo compartment cannot be filled. When the cargo compartment cannot be filled, the partition can be installed close to the stacked cargo, thereby reducing the area that needs to be refrigerated and saving refrigeration resources.

[0029] 3. The sliding partition allows for automatic movement and adjustment via control components, eliminating the need for manual movement and improving work efficiency. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0039] This application discloses an intelligent equalization refrigeration device for cold chain transportation.

[0040] Reference Figure 1 and Figure 2 A smart balanced refrigeration device for cold chain transportation includes a rectangular, hollow cargo compartment 1. A hinged door 11 for easy loading is installed at the rear end of the cargo compartment 1. A refrigeration unit 2 for supplying cold air into the cargo compartment 1 is installed at the end of the cargo compartment 1 away from the door 11. The refrigeration unit 2 is located at the end of the cargo compartment 1 and near the top. An automatic control device for controlling the refrigeration unit 2 and monitoring the internal temperature of the cargo compartment 1 in real time is also installed on the cargo compartment 1. A cold air circulation device 4 for circulating the cold air inside the cargo compartment 1 is also installed. During the transportation of goods, the refrigeration unit 2 supplies cold air into the cargo compartment 1. Under the action of the cold air circulation device 4, the temperature inside the cargo compartment 1 reaches the temperature required for the transportation of goods. When the temperature reaches the set value, the refrigeration unit 2 stops operating. When the automatic control device detects that the internal temperature of the cargo compartment 1 is lower than the set value, the automatic control device automatically controls the refrigeration unit 2 to start and continue supplying cold air into the cargo compartment 1, so that the interior of the cargo compartment 1 always maintains a constant temperature for the transportation of goods.

[0041] The automatic control device includes a controller and multiple temperature sensors 3 installed inside the cargo compartment 1. The temperature sensors 3 are electrically connected to the controller. The temperature sensors 3 are located near the rear of the cargo compartment 1 and are used to monitor the temperature inside the cargo compartment 1 in real time. When the temperature inside the cargo compartment 1 is lower than the set value, a signal is transmitted to the refrigeration equipment 2 to start it. When the temperature inside the cargo compartment 1 reaches the set value, the controller controls the refrigeration equipment 2 to stop running, so as to avoid the refrigeration equipment 2 from running for a long time and consuming too many resources.

[0042] Inside the cargo compartment 1, a partition device 5 is installed to divide the interior of the cargo compartment 1 into two parts. The partition device 5 includes a partition plate 51 that slides inside the cargo compartment 1. The partition plate 51 is set along the cross-section of the cargo compartment 1 and can slide along the length of the cargo compartment 1. When the goods to be transported cannot fill the entire cargo compartment 1, the goods are stacked from the front of the cargo compartment 1, and then the partition plate 51 is slid to bring it closer to the stacked goods. The sliding partition plate 51 can divide the interior of the cargo compartment 1 into a storage area 12 for storing goods and an empty area 13, so that the cold air generated by the refrigeration equipment 2 only circulates in the storage area 12, avoiding the cold air from circulating throughout the entire cargo compartment 1 and avoiding waste of cold air. Furthermore, the partition plate 51 is composed of two pieces of the same size spliced ​​together, which makes it convenient for workers to quickly pick up and assemble the partition plate 51 when dividing the storage area 12 and the empty area 13.

[0043] Reference Figure 2 and Figure 3 The partition device 5 also includes a partition assembly 52 slidably disposed inside the cargo compartment 1 for mounting the partition plate 51, and a control assembly 53 disposed inside the cargo compartment 1 for controlling the sliding of the partition plate 51. The control assembly 53 is disposed inside the cargo compartment 1 near the top. The partition assembly 52 includes a U-shaped partition frame 521 slidably disposed inside the cargo compartment 1. The partition frame 521 includes a horizontally arranged horizontal plate 5211 and a pair of vertically arranged vertical plates 5212. The upper ends of the two vertical plates 5212 are vertically fixed to both ends of the horizontal plate 5211, and the lower ends of the two vertical plates 5212 are slidably engaged with the cargo compartment 1. On the inner bottom surface of compartment 1, a horizontal plate 5211 is set near the inner top wall of compartment 1; two partition plates 51 are hinged to two vertical plates 5212 on the partition frame 521. By rotating the partition plates 51, the connection or closure of the storage area 12 and the blank area 13 can be controlled. In addition, during the loading process, the rotating partition plates 51 are easier to open and close; the lower end of the partition plate 51 abuts against the bottom surface of compartment 1, and a flexible sealing block is fixed on the partition plate 51 near its lower end. The sealing block can seal the gap between the partition plate 51 and the bottom surface of compartment 1.

[0044] Reference Figure 2 , Figure 3 and Figure 4The partition assembly 52 also includes two sets of guide rods 522 fixed on the inner walls of both sides of the cargo compartment 1. Each set of guide rods 522 includes two guide rods 522. The two guide rods 522 are arranged along the length direction of the cargo compartment 1. The two guide rods 522 on the inner wall of the cargo compartment 1 on the same side are arranged in parallel. The two sets of guide rods 522 are arranged along the height direction of the cargo compartment 1. One set is set at both ends of the horizontal plate 5211 of the partition frame 521, and the other set is set at the lower end of the vertical plate 5212 of the partition frame 521. Sliding grooves 523 are provided at both ends of the horizontal plate 5211 and the corresponding vertical plate 5212. The guide rods 522 and the sliding grooves 523 slide together, so that the partition frame 521 can slide along the direction of the guide rods 522 and ensure that the partition frame 521 is more stable during the sliding process.

[0045] The control assembly 53 includes a pair of control components for connecting the partition frame 521 and a control motor 531 fixed to the inner wall of the cargo compartment 1 and near the refrigeration equipment 2. The two sets of control components are symmetrically arranged on the two side walls inside the cargo compartment 1. The control components include a pair of synchronous pulleys 532 rotatably mounted on the inner wall of the cargo compartment 1 and a toothed belt 533 sleeved on the two synchronous pulleys 532. The two synchronous pulleys 532 are symmetrically arranged inside the cargo compartment 1 and near both ends. The toothed belt 533 is arranged along the length of the cargo compartment 1, and the lower side of the toothed belt 533 is fixed to the cross plate 5211 of the partition frame 521. The inner side of the toothed belt 533 is provided with multiple tooth blocks, and the synchronous pulleys 532 are provided with corresponding tooth grooves. The synchronous pulleys 532 on the two sets of control components are at the same horizontal position, and the two synchronous pulleys 532 located at the same end are... A synchronous shaft 534 is fixedly connected between the synchronous pulleys 532. The synchronous shaft 534 passes through the axis of the synchronous pulleys 532, and both ends of the synchronous shaft 534 are fixed to the inner wall of the cargo box 1. The synchronous pulleys 532 rotate on the synchronous shaft 534. The control motor 531 is a double-headed motor, which is located in the middle position of the synchronous shaft 534, and the two output shafts of the control motor 531 are fixed to the synchronous shaft 534. After the goods in the cargo box 1 are loaded, the control motor 531 is started and drives the synchronous shaft 534 to rotate, thereby controlling the synchronous pulleys 532 and the toothed belt 533 to rotate. During the rotation of the toothed belt 533, the separator 521 is driven to move along the length of the guide rod 522, so that the separator 521 and the separator plate 51 are as close as possible to the stacked goods, controlling the size of the storage area 12, and allowing the cold air to circulate only within the storage area 12.

[0046] Reference Figure 2 , Figure 3 and Figure 4A rectangular protective shell 54 is provided on the outside of both the control component and the control motor 531 to prevent the cold air inside the cargo compartment 1 from affecting the normal operation of the control motor 531 or hardening the toothed belt 533 and affecting its normal use. A sliding hole 541 with the same length direction as the protective shell 54 is opened on the lower side of the protective shell 54 of the control component. A connecting rod 55 is fixed on the cross plate 5211 on the partition frame 521. The other end of the connecting rod 55 is fixed to the toothed belt 533. The connecting rod 55 is slidably engaged at the sliding hole 541. A flexible and elastic windproof curtain 542 is fixed on the protective shell 54 at the sliding hole 541. The windproof curtain 542 seals the sliding hole 541 without affecting the normal sliding of the connecting rod 55 and preventing cold air from entering the interior of the protective shell 54. A flexible wind deflector 56 is fixed on the horizontal plate 5211 of the partition frame 521. The upper side of the wind deflector 56 is sealed against the top wall of the cargo compartment 1, and its two ends are sealed against the protective shell 54 on the control component. This can effectively prevent cold air leakage from the storage area 12 and improve the heat preservation effect of the storage area 12. The temperature sensor 3 is installed on the horizontal plate 5211 of the partition frame 521. Since the density of cold air is greater than that of hot air, the cold air in the storage area 12 will accumulate in the cargo compartment 1 near the bottom. Therefore, placing the temperature sensor 3 at a higher position can make the monitored temperature of the cargo compartment 1 more accurate.

[0047] The airflow device 4 includes a cross-flow fan 41 mounted on the inner side of the partition 51 facing the storage area 12 and a pair of air guide blocks 42 fixed on the inner wall of the cargo compartment 1. The cross-flow fan 41 is installed on the two partitions 51 near the bottom of the cargo compartment 1. The air inlet of the cross-flow fan 41 is horizontally positioned facing the front of the vehicle, and its outlet is vertically upward. The outlet of the refrigeration equipment 2 is vertically downward. The cross-flow fan 41 and the refrigeration equipment 2 are diagonally positioned inside the storage area 12. The cold air blown by the refrigeration equipment 2 can blow towards the bottom of the cargo compartment 1, and then the cross-flow fan 41 blows the cold air upward. Through the cooperation of both, the cold air circulates in the storage area 12, preventing cold air from accumulating at the bottom of the cargo compartment 1. Both air guide blocks 42 are positioned along the width of the cargo compartment 1 and are correspondingly installed on the cross-flow fan 41. On the partition plate 51 directly above the fan 41 and on the bottom surface of the cargo compartment 1 directly below the refrigeration equipment 2, the air guide blocks 42 on the partition plate 51 are divided into two parts, which do not affect the opening and closing of the partition plate 51. The two air guide blocks 42 are set diagonally, and are located at the four vertices of the rectangle with the cross-flow fan 41 and the refrigeration equipment 2 respectively. The air guide blocks 42 are provided with arc-shaped air guide surfaces 421, which can change the air blown on the air guide blocks 42 from a vertical state to a horizontal state. The air outlets of the refrigeration equipment 2 and the cross-flow fan 41 are both aligned with the air guide surfaces 421. The air guide surfaces 421 allow the cold air blown out by the refrigeration equipment 2 to flow in a better circular manner inside the storage area 12 in conjunction with the cross-flow fan 41, thereby ensuring that the temperature inside the storage area 12 is always in a balanced state and avoiding large temperature differences between different areas.

[0048] Reference Figure 2 , Figure 3 and Figure 4The partition assembly 52 also includes a reset member 524 disposed on the partition frame 521. Multiple sets of reset members 524 are disposed on both partition plates 51. The multiple sets of reset members 524 are evenly disposed along the length direction of the partition plate 51 and are located at the hinge position between the partition plate 51 and the partition frame 521. The partition plate 51 is hinged to the partition frame 521 through a rotating shaft 5241. The reset member 524 includes a guide ring 5242 fixed on the partition frame 521 and having an annular structure. The guide ring 5242 is horizontally disposed and passes through the partition plate 51. The partition plate 51 and the guide ring 5242 are rotatably engaged, and the partition plate 51 can rotate along the annular direction of the guide ring 5242. The reset component 524 also includes a pair of reset springs 5243 sleeved on the guide ring 5242. The two reset springs 5243 are symmetrically arranged on both sides of the partition plate 51. One end of the reset spring 5243 is fixed to the partition plate 51, and the other end is fixed to the vertical plate 5212 of the partition frame 521. Under the action of the reset component 524, the two partition plates 51 can always be kept closed, so that the storage area 12 can always be kept in a closed environment to prevent the leakage of cold air inside. There are energized magnetic suction components fixed on the inner and outer sides of the partition plate 51. During the loading process, the partition plate 51 is fixed to the inner wall of the cargo compartment 1 by the magnetic suction components. After the loading is completed, the partition plate 51 can be automatically closed after the magnetic suction components are de-energized.

[0049] The implementation principle of the intelligent balanced refrigeration device for cold chain transportation in this application embodiment is as follows: After the goods in the cargo compartment 1 are loaded and unloaded, the partition plate 51 is controlled to slide towards the stacked goods, thereby changing the area in the cargo compartment 1 that needs to be refrigerated, avoiding the waste of a large amount of cold air. During the flow of cold air in the storage area 12, the cold air can circulate in a ring within the storage area 12 through the set cross-flow fan 41 and air guide block 42, avoiding the accumulation of cold air at the bottom of the cargo compartment 1, so that the cold air can fill every position, making the temperature in the cargo compartment 1 more uniform, and can monitor the temperature in the cargo compartment 1 in real time according to the set temperature sensor 3, and control the refrigeration equipment 2 to work dynamically.
