[0002] In the field of experimental animal transportation, the refrigeration system of the experimental animal transport vehicle commonly used in the current market directly conveys cold air to the interior of the carriage. Although this refrigeration method can quickly reduce the temperature inside the carriage, due to the sudden change of the environment, it often triggers stress reactions such as panic and agitation of experimental animals.

[0003] For an existing experimental animal transport vehicle, reference can be made to an experimental animal transport vehicle with the publication number CN204726303U, which includes a carriage and an air conditioner. The air conditioner includes pipelines, an indoor unit, and an outdoor unit. The indoor unit is arranged inside the front part of the carriage, the outdoor unit is arranged at the front side of the bottom of the carriage, and the indoor unit and the outdoor unit are connected through pipelines. The carriage includes an air supply port and an air exhaust port. A blower is provided at the air supply port, and an exhaust fan is provided at the air exhaust port. In the prior art, only a simple air conditioner is relied on to adjust the temperature inside the carriage, resulting in poor air quality inside the carriage, which easily causes discomfort to animals during long-distance transportation and increases the unstable factors during the transportation process.

[0004] Therefore, how to improve the air quality inside the carriage has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0007] The independent refrigeration unit is arranged on the outer side wall at the front end of the carriage, and the air outlet end of the independent refrigerator extends into the interior of the air mixing chamber;

[0008] The air inlet of the air mixing chamber is communicated with the outside of the carriage, and the fresh air device is installed in the air mixing chamber and located at the air inlet;

[0009] The air outlet chamber is located on the inner top wall of the carriage and is communicated with the air outlet of the air mixing chamber. Two or more air outlet holes are opened on both sides of the air outlet chamber facing the side wall of the carriage;

[0010] Two or more cage racks are provided inside the carriage, and the cage racks are suitable for placing animal cages.

[0011] In a possible implementation manner, there are three cage racks, and the three cage racks are respectively attached to the three inner side walls of the carriage.

[0012] In a possible implementation, a support partition is fixedly provided on the cage frame, and ventilation mesh holes are formed on the support partition, and the ventilation mesh holes are arranged in an array.

[0013] In a possible implementation, the main body of the air outlet compartment is in a cuboid structure, the length direction of the air outlet compartment is parallel to the length direction of the carriage, and the air outlet compartment is located between two opposite cage frames.

[0014] In a possible implementation, more than two support rods are provided between two opposite cage frames.

[0015] In a possible implementation, more than two restraint straps are provided on the side of the cage frame facing away from the inner side wall of the carriage, and the more than two restraint straps are arranged at equal intervals along the length direction of the cage frame.

[0016] In a possible implementation, exhaust channels are formed on both sides of the carriage, and the carriage communicates with the outside through the exhaust channels, which is suitable for balancing the air pressure inside the carriage.

In some instances, methods, means, elements, and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0035] An experimental animal transport vehicle, as Figures 1 to 6 shown, includes: a carriage 110, an independent refrigeration unit 120, a fresh air device 130, and an air outlet compartment 140; the carriage 110 is adapted to be mounted on a motor vehicle chassis, and an air mixing chamber 150 is provided at the front end inside the cavity of the carriage 110; a door 111 for opening or closing the carriage 110 is provided at the rear end of the carriage 110; the independent refrigeration unit 120 is disposed on the outer side wall at the front end of the carriage 110, and the air outlet end of the independent refrigeration unit 120 extends into the interior of the air mixing chamber 150; the air inlet of the air mixing chamber 150 is communicated with the outside of the carriage 110, and the fresh air device 130 is installed in the air mixing chamber 150 and located at the air inlet; the air outlet compartment 140 is located on the inner top wall of the carriage 110 and is communicated with the air outlet of the air mixing chamber 150, and two or more air outlet holes 141 are formed on both sides of the air outlet compartment 140 facing the side wall of the carriage 110; two or more cage racks 200 are provided in the carriage 110.

[0036] It should be noted here that the transport vehicle uses a van of model Yutong ZKH5045XLCBEV3A in the prior art. The main body of the carriage 110 is a rectangular hollow box structure. The carriage 110 is suitable for providing a closed and safe transport environment for transporting experimental animals. The independent refrigeration unit 120 is suitable for providing stable cold air for the carriage 110. The independent refrigeration unit 120 is fixedly installed on the outer side wall at the front end of the carriage 110 and the air outlet end extends into the interior of the air mixing chamber 150, so as to ensure that the cold air sent out by the independent refrigeration unit 120 directly reaches the inside of the air mixing chamber 150. Among them, the independent refrigeration unit 120 uses the model Thermo King T-800 in the prior art. The fresh air device 130 is suitable for introducing fresh air from the outside into the interior of the carriage 110. The fresh air device 130 is installed in the air mixing chamber 150 and is located at the air inlet, so as to ensure that fresh air can smoothly enter the air mixing chamber 150. The air mixing chamber 150 is suitable for mixing the fresh air from the outside with the cold air generated by the independent refrigeration unit 120, so as to provide a fresh and oxygen-rich environment for the experimental animals in the carriage 110. Preferably, the mixing ratio of the fresh air in the air mixing chamber 150 to the cold air generated by the independent refrigeration unit 120 is 4:1. It should be pointed out here that the fresh air device 130 is an intake fan. The air outlet chamber 140 is communicated with the air mixing chamber 150, so as to ensure that the air outlet chamber 140 evenly distributes the air mixed in the air mixing chamber 150 through the air outlet holes 141 to all corners of the carriage 110, ensuring uniform air circulation in the carriage 110. The cage rack 200 in the carriage 110 is suitable for placing experimental animals.

[0037] By setting the fresh air device 130, the fresh air device 130 introduces the fresh air in the outside atmosphere into the air mixing chamber 150, and the mixed air enters the carriage 110, thereby reducing the concentration of carbon dioxide in the carriage 110, effectively improving the air quality in the carriage 110, and ensuring the freshness and cleanliness of the air in the carriage 110. At the same time, through the mutual cooperation of the air mixing chamber 150, the independent refrigeration unit 120 and the fresh air device 130, the temperature and air quality in the carriage 110 are adjusted, providing a stable transport environment and good air quality for the experimental animals, reducing the stress response of the animals during transportation, and improving the comfort and survival rate of the animals.

[0038] Furthermore, as Figures 1 to 4As shown in the figure, both the air mixing chamber 150 and the independent refrigeration unit 120 are fixedly arranged on the inner and outer sides of the front side wall of the carriage 110 by welding. The air supply duct 121 of the independent refrigeration unit 120 penetrates through the outer side wall of the front end of the carriage 110 and extends into the inner cavity of the air mixing chamber 150. A through hole 112 matching the air inlet of the air mixing chamber 150 is provided on the outer side wall of the front end of the carriage 110. The air inlet of the air mixing chamber 150 is communicated with the through hole 112, so that the air inlet of the air mixing chamber 150 is communicated with the outside through the through hole 112.

[0039] Further, as Figure 3 , Figure 4 shown, there are three cage frames 200, and the three cage frames 200 are respectively attached to the inner side wall of the carriage 110. It should be noted here that as Figure 3 shown, the height h2 of the two cage frames 200 arranged oppositely along the length direction of the carriage 110 is greater than the height h3 of the cage frame 200 arranged along the width direction of the carriage 110. The difference between the height h1 of the carriage 110 and the height h3 of the cage frame 200 arranged along the width direction of the carriage 110 is greater than the height h4 of the air mixing chamber 150, which is suitable for providing an installation space for the air mixing chamber 150. The air mixing chamber 150 is fixedly installed in the carriage 110 and is located above the cage frame 200 arranged along the width direction of the carriage 110. The three cage frames 200 are respectively attached to the inner side wall of the carriage 110. Through this setting method of the cage frame 200, the vertical space of the carriage 110 can be fully utilized, and at the same time, the passage left between the two relatively arranged cage frames 200 is convenient for the staff to carry out work such as loading and unloading animals, replacing cages, and daily inspection of animals in the carriage 110.

[0040] Further, the air outlet chamber 140 is located between the two relatively arranged cage frames 200 and the air outlet chamber 140 is fixedly installed on the inner top wall of the carriage 110. The air outlet holes 141 are arranged towards both sides of the side wall of the carriage 110. After the mixed air in the air outlet chamber 140 is discharged from the air outlet holes 141, by using the principle of gravity and air flow, the mixed air diffuses downward and is evenly distributed inside the carriage 110, providing a comfortable transportation environment for the experimental animals, avoiding the direct blowing of the experimental animals on the cage frame 200 by the air outlet chamber 140 and causing stress reactions of the experimental animals, and ensuring the relatively uniform air temperature and quality inside the carriage 110.

[0041] In one possible implementation, the main body of the air outlet bin 140 is a hollow rectangular structure, which is more likely to form laminar flow when air flows, reducing the generation of eddies and dead corners, which helps to avoid the mixed air from being retained in the air outlet bin 140 and ensure smooth air circulation. More than two air outlet holes 141 are arranged in an array along the body length direction on both sides of the air outlet bin 140. The array-arranged air outlet holes 141 can ensure that the mixed air is evenly distributed in the air outlet bin 140 and is simultaneously delivered from both sides of the air outlet bin 140, ensuring that the air mixing bin 150 distributes the mixed air evenly to all corners of the compartment 110 through the air outlet holes 141.

[0042] In one possible implementation, Figure 6 As shown, a supporting partition 230 is fixedly provided on the cage frame 200 , and ventilation mesh holes 231 are opened on the supporting partition 230 , and the ventilation mesh holes 231 are arranged in an array. It should be noted here that the cage 200 is formed by more than two horizontal beams and more than two vertical beams, and the support partition 230 is fixedly arranged on the cage 200. The length direction of the support partition 230 is perpendicular to the length direction of the vertical beam of the cage 200. The support partition 230 is suitable for dividing the internal space of the cage 200 into different areas, so that the cage 200 can accommodate more experimental animals while maintaining the relative independence of each area. The support partition 230 is provided with a ventilation mesh 231, and the ventilation mesh 231 allows air to flow freely inside the cage 200, thereby reducing the odor in the compartment 110 and ensuring the freshness and dryness of the air in the box. The ventilation mesh 231 is arranged in an array, which can ensure that the air is evenly distributed and efficiently circulated in the cage 200, which helps to improve the ventilation efficiency and reduce ventilation dead corners and blind spots.

[0043] Furthermore, more than two supporting baffles 230 are provided, and the more than two supporting baffles 230 are relatively arranged on the cage frame 200 .

[0044] In a possible implementation, two or more support rods (not shown) are provided between two cages 200 that are arranged opposite to each other along the length direction of the carriage 110. It should be noted here that the support rods are fixedly arranged between the opposite cages 200 and are located at the top of the cages 200. The support rods provide a stable support force for the cages 200, so that the cages 200 are always kept in a relatively fixed position, avoiding displacement or tipping of the cages 200 during transportation, ensuring the stability between the cages 200, and the two or more support rods are equidistantly arranged along the length direction of the cages 200, reducing the shaking and displacement of the cages 200, and ensuring the stability of the cages 200.

[0045] In a possible implementation, on the side of the cage frame 200 facing away from the inner wall of the carriage 110, there are provided more than two restraint straps (not shown in the figure), and the more than two restraint straps are equidistantly arranged along the length direction of the cage frame 200.

[0046] It should be noted here that the restraint straps are suitable for preventing the experimental animals on the cage frame 200 from tipping over or falling during transportation due to factors such as sharp turns and braking. By equidistantly arranging the restraint straps along the length direction of the cage frame 200, multiple stable support points can be formed. These support points act together to significantly enhance the lateral stability of the cage frame 200, thereby ensuring the safety of transportation.

[0047] Furthermore, as Figure 6 shown, a limit ring 240 is fixedly provided on the cross beam of the cage frame 200. The limit rings 240 are equidistantly arranged along the length direction of the cross beam of the cage frame 200. The restraint straps pass through the limit rings 240. The limit rings 240 provide additional support points for the restraint straps, which helps to disperse the tension on the restraint straps and prevent the restraint straps from breaking due to excessive single-point force. At the same time, the limit rings 240 also help to fix the position of the restraint straps, making them fit more stably on the cage frame 200.

[0048] In a possible implementation, as Figure 2 shown, exhaust channels are provided on both sides of the carriage 110. The carriage 110 communicates with the outside through the exhaust channels, which is suitable for balancing the air pressure inside the carriage 110. It should be noted here that the exhaust channels are exhaust plates 310. The exhaust plates 310 are fixedly installed on the carriage 110 and are located on the side walls on both sides of the middle of the carriage 110. The main body of the exhaust plate 310 is in a rectangular plate-like structure. Exhaust holes 311 are provided on the exhaust plate 310. The exhaust holes 311 are arranged in an array. By providing the exhaust channels, the carriage 110 communicates with the outside through the exhaust holes 311 of the exhaust channels. Harmful substances such as dirty air, odors, and moisture inside the carriage 110 are discharged through the exhaust holes 311 of the exhaust channels, so as to keep the air pressure inside the carriage 110 balanced with the outside air pressure, which helps to improve the air quality inside the carriage 110 and reduce the discomfort and stress reactions of animals due to poor air quality.

[0049] In a possible implementation manner, a rain shield 160 is provided at the air inlet of the air mixing chamber 150. It should be noted here that the rain shield 160 is fixedly arranged at the through hole 112 on the outer side wall of the carriage 110 and is located at the air inlet of the air mixing chamber 150. The rain shield 160 is suitable for preventing rainwater or external impurities from entering the interior of the carriage 110 through the air mixing chamber 150, ensuring the freshness and cleanliness of the air inside the carriage 110. The main body of the rain shield 160 is in an inverted 'L' shape structure and the opening is arranged towards the air inlet of the air mixing chamber 150. By setting the rain shield 160, while blocking rainwater, it does not affect the normal air intake of the fresh air device 130, which helps to optimize the air flow in the mixing chamber and improve the mixing efficiency of the fresh air and the air inside the carriage 110. By setting the rain shield 160, it is avoided that external rainwater or impurities enter the interior of the carriage 110 through the air mixing chamber 150.

[0050] In a possible implementation manner, it further includes a split unit condenser 410 and a split unit evaporator 420; the split unit condenser 410 is located at the bottom of the carriage 110, the split unit evaporator 420 is located inside the cavity of the carriage 110, and the split unit condenser 410 is communicated with the split unit evaporator 420. It should be noted here that the split unit condenser 410 is fixedly installed at the bottom of the outer side wall of the carriage 110 through bolts, the split unit evaporator 420 is fixedly installed inside the box body of the carriage 110 through bolts, the split unit condenser 410 is communicated with the split unit evaporator 420 inside the carriage 110 after passing through the outer side wall of the carriage 110 through pipelines. The split unit condenser 410 and the split unit evaporator 420 adopt the model of Carrier SV-400 in the prior art. When the independent refrigeration unit 120 fails or cannot operate normally, the split unit condenser 410 and the split unit evaporator 420 can quickly take over the work, so as to ensure that the temperature inside the carriage 110 is maintained within a suitable range to protect the health and safety of experimental animals. By adding the split unit condenser 410 and the split unit evaporator 420, the risk of transportation interruption caused by the failure of the independent refrigeration unit 120 is reduced, ensuring the smooth progress of the transportation plan and improving the transportation efficiency.
