Description

Technical Field

[0001] The utility model relates to the technical field of cold chain transportation, in particular to a cold chain transportation cooling structure. Background Art

[0002] In today's globalized world, cold chain transportation plays a vital role. Cold chain transportation involves using a series of technical means and equipment to ensure that goods are kept in a specific low-temperature environment throughout the transportation process, thereby guaranteeing their quality and safety. There are various methods of cold chain transportation, but road cold chain transportation offers flexibility and convenience, enabling door-to-door service and is suitable for short- to medium-distance cargo transportation.

[0003] However, during cold chain transportation, abnormal air supply often occurs, resulting in uneven distribution of cold air, posing a serious threat to the quality and safety of goods. This abnormal air supply mainly manifests as unstable cold air supply and localized excessively high or low temperatures. This uneven cold air distribution can cause different parts of the goods to be affected by different degrees of temperature. Some parts may deteriorate faster due to excessive temperatures, while others may suffer frostbite due to excessively low temperatures. Based on this, those skilled in the art have proposed a cooling structure for cold chain transportation. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings existing in the prior art and to propose a cold chain transportation cooling structure. The designed cold chain transportation cooling structure utilizes multiple top sealing plates to simultaneously coordinate the temperature inside the carriage. The device provides cold source cold air at the same time through multiple top sealing plates arranged on the top of the carriage, thereby improving the uniformity of the temperature inside the carriage.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A cold chain transport cooling structure comprises a cargo box frame, wherein the upper side wall of the cargo box frame is paved with and installed with a plurality of top sealing plates, wherein the upper side wall of the top sealing plate is fixedly connected to a plurality of air intake pipes, wherein the outer side wall of the air intake pipe is installed with a main valve port, wherein an expansion bag is provided inside the air intake pipe, wherein the expansion bag is connected to the main valve port, wherein side panels are installed on the front and rear and left and right side walls of the cargo box frame, wherein an air pump is installed on the side panels, wherein a three-way valve is installed on the air pump, wherein one interface of the three-way valve is connected to a second cold air pipe, wherein the second cold air pipe is connected to the main valve port;

[0007] Through the above technical solution, the cooling structure uses multiple top sealing plates to simultaneously coordinate the temperature inside the car. In order to avoid uneven temperature inside the car, the device provides cold air from the cold source through multiple top sealing plates set on the top of the car, thereby improving the uniformity of the temperature inside the car. At the same time, when the temperature at a certain position in the car suddenly drops, the air pump at that position supplies air to the expansion bag through the three-way valve, and the gas enters the expansion bag from the second cold air pipe, causing the expansion bag to begin to expand, thereby blocking the air intake pipe for air supply. Since the flow rate of the cold air source entering the air intake pipe is reduced, the temperature at that location begins to rise, thereby effectively providing uniformity of the temperature inside the car.

[0008] Furthermore, another interface of the three-way valve is connected to a first cooling air pipe, the bottom of the first cooling air pipe is arranged at the bottom of the vehicle compartment, and an air outlet valve is arranged at the bottom of the expansion bag;

[0009] Through the above technical solution, in order to improve the uniformity of the temperature inside the car, the air pump draws the cold air at the bottom of the car into the expansion bag through the first cold air pipe, and then the expansion bag discharges the cold air back to the top of the car through the air outlet valve at its bottom, thereby realizing the internal circulation of cold air inside the car.

[0010] Furthermore, a hot air pipe is connected to the other interface of the three-way valve, and the hot air pipe passes through the side panel to the outside, and a compartment door is installed on the front side wall of the cargo box frame;

[0011] Through the above technical solution, when the cooling supply inside the carriage is abnormal, in order to prevent the materials stored inside the carriage from being frozen, the air pump will draw the external hot air into the expansion bag through the hot air pipe, and then the hot air will be discharged into the carriage through the outlet valve, thereby preventing the materials inside the carriage from being frozen. At the same time, if someone accidentally enters the carriage and cannot open the carriage door, this method can be used to restore the temperature inside the carriage, thereby avoiding accidents.

[0012] Furthermore, the bottom of the cargo box frame is paved with a plurality of bottom plates, and the bottom plates are provided with a plurality of non-through trough structures;

[0013] Through the above technical solution, cold air can enter the non-penetrating trough of the bottom plate and then come into contact with the bottom of the materials, avoiding storage problems caused by the bottom of the materials being unable to contact the cold air.

[0014] Furthermore, a number of temperature detectors matching the number of air pumps are installed on the side panel, and the temperature detectors are electrically connected to the air pump, the three-way valve, the main valve port and the air outlet valve;

[0015] Through the above technical solution, the temperature detector is used to detect the local temperature change inside the car, and the air pump, three-way valve, main valve port and outlet valve are controlled respectively according to the detected temperature signal.

[0016] The utility model has the following beneficial effects:

[0017] In the present invention, the device provides cold air from a cold source at the same time through multiple top sealing plates arranged on the top of the car, thereby improving the uniformity of the temperature inside the car. At the same time, when the temperature at a certain position in the car suddenly drops, the air pump at that position supplies air to the expansion bag through the three-way valve, and the gas enters the expansion bag from the second cold air pipe, causing the expansion bag to begin to expand, thereby blocking the air intake pipe used for air supply. Since the flow rate of the cold air source entering the air intake pipe is reduced, the temperature at that position begins to rise, thereby effectively providing uniformity of the temperature inside the car.

[0018] In the present invention, in order to improve the uniformity of the temperature inside the car, the air pump draws the cold air at the bottom of the car into the expansion bag through the first cold air pipe, and then the expansion bag discharges the cold air back to the top of the car through the air outlet valve at its bottom, thereby realizing the internal circulation of the cold air inside the car.

[0019] In the utility model, when the cooling inside the carriage is abnormal, in order to prevent the materials stored inside the carriage from being frozen, the air pump will draw the external hot air into the expansion bag through the hot air pipe, and then the hot air will be discharged into the carriage through the air outlet valve, thereby preventing the materials inside the carriage from being frozen. At the same time, if someone accidentally enters the carriage and is unable to open the carriage door, this method can be used to restore the temperature inside the carriage, thereby avoiding the occurrence of accidents.

In order to avoid uneven temperature inside the car, the device provides cold air from a cold source at the same time through multiple top sealing plates 2 set on the top of the car, thereby improving the uniformity of the temperature inside the car. At the same time, when the temperature at a certain position in the car suddenly drops, the air pump 15 at that position supplies air to the expansion bag 13 through the three-way valve 8, and the gas enters the expansion bag 13 from the second cold air pipe 11, causing the expansion bag 13 to begin to expand, thereby blocking the air intake pipe 4 for air supply. Since the flow rate of the cold air source entering the air intake pipe 4 is reduced, the temperature at that position begins to rise, thereby effectively providing uniformity of the temperature inside the car.

[0028] The other interface of the three-way valve 8 is connected with the first cold air pipe 10. The bottom of the first cold air pipe 10 is set at the bottom of the car.

At the same time, the air pump 15 The cold air at the bottom of the car is drawn into the expansion bag 13 through the first cold air pipe 10, and then the expansion bag 13 discharges the cold air back to the top of the car through the air outlet valve 14 at its bottom, thereby realizing the internal circulation of cold air inside the car, further improving the uniformity of the temperature inside the car. When the cooling inside the car is abnormal, in order to prevent the materials stored inside the car from being frozen, the air pump 15 will draw the external hot air into the expansion bag 13 through the hot air pipe 9, and then the hot air is discharged into the car through the air outlet valve 14, thereby preventing the materials inside the car from being frozen. At the same time, if someone accidentally enters the car and cannot open the car door 3, this method can be used to restore the temperature inside the car, thereby avoiding the occurrence of accidents.
