Technical Field

[0001] The utility model relates to the technical field of goods transportation, in particular to a goods transportation device for international trade. Background Art

[0002] In international trade, goods transportation devices play a crucial role. They not only carry goods but also need to protect the goods from various environmental factors during long-distance transportation, especially the threat of a humid environment.

[0003] Traditional goods transportation devices often have many deficiencies in moisture-proof design. Firstly, limitations in material selection result in poor moisture-proof performance of the device itself, making it easy to absorb moisture in a humid environment, thus affecting the quality and safety of the goods. Secondly, the sealing performance of traditional devices is not ideal, with gaps or holes, allowing external moisture to easily penetrate into the device interior, increasing the risk of goods getting damp. Therefore, to solve the above problems, this device designs a goods transportation device for international trade. Summary of the Utility Model

[0019] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] Referring to the attached Figures 1-3, a cargo transportation device for international trade proposed by the present utility model includes a cargo transportation box body 10. An air inlet pipe 11 is installed on one side side wall of the cargo transportation box body 10. A gas exchange pipe 12 is installed on the opposite side wall of the cargo transportation box body 10 where the air inlet pipe 11 is located. An air exchange mechanism is arranged inside the gas exchange pipe 12. The air exchange mechanism includes a negative pressure fan 22 installed on the inner wall of the gas exchange pipe 12. A humidity sensor b 26 is installed on the inner top wall of the cargo transportation box body 10. A controller 25 is also installed outside the cargo transportation box body 10. The humidity sensor b 26 and the negative pressure fan 22 are respectively electrically connected to the controller 25. Among them, the provided humidity sensor b 26 is used to detect the humidity of the air inside the cargo transportation box body 10. If the humidity exceeds the preset threshold range, the detected electrical signal is sent to the controller 25, and the controller 25 controls the negative pressure fan 22 to start, thereby pumping out the air inside the cargo transportation box body 10, and then realizing the exchange of the air inside the cargo transportation box body 10.

[0022] A humidity sensor a 21 is also installed on the gas exchange pipe 12. The detection end of the humidity sensor a 21 extends into the inside of the gas exchange pipe 12. The humidity sensor a 21 is electrically connected to the controller 25. Among them, the provided humidity sensor a 21 can detect the humidity of the air entering the inside of the gas exchange pipe 12, and combine with the humidity sensor b 26 to judge the humidity range after the gas inside the cargo transportation box body 10 is replaced. When the humidity detected by both the humidity sensor b 26 and the humidity sensor a 21 is within the set threshold range, after the controller receives the signal, it controls the negative pressure fan 22 to stop working.

[0023] A drying mechanism is arranged inside the air inlet pipe 11. The drying mechanism includes an electric heating wire 23 installed inside the air inlet pipe 11. The electric heating wire 23 is electrically connected to the controller 25. Among them, when replacing the air, in order to reduce the entry of humid air from the outside into the cargo transportation box body 10, the electric heating wire 23 is provided here. When the negative pressure fan 22 starts, the controller 25 controls the electric heating wire 23 to start. At this time, the electric heating wire 23 heats the humid air entering the inside of the air inlet pipe 11, so that the moisture in the air evaporates and condenses on the surface near the heating wire, thereby reducing the humidity of the air entering the container.

[0024] A first mesh plate 32 and a second mesh plate 33 are fixedly installed inside the air inlet pipe 11. A drying chamber 31 is formed between the first mesh plate 32 and the second mesh plate 33. A molecular sieve desiccant 38 is arranged inside the drying chamber 31. Among them, in order to further improve the dryness of the gas entering the cargo transportation box body 10, the molecular sieve desiccant 38 is provided here to further filter the air, so as to adsorb a small amount of residual moisture through the molecular sieve desiccant 38, and then the inside of the cargo transportation box body 10 can be replaced with dry gas.

[0025] An air inlet pipe 11 is provided with a feed inlet 34 and a material taking port 36 on its outer wall, which are communicated with the inside of the drying chamber 31. A first threaded plug 35 is threadedly installed on the inner wall of the feed inlet 34, and a second threaded plug 37 is threadedly connected to the inner wall of the material taking port 36. Among them, when the molecular sieve desiccant 38 is saturated, the molecular sieve desiccant 38 can be replenished and replaced here. After the second threaded plug 37 is opened, the molecular sieve desiccant 38 can be taken out of the drying chamber 31. After the first threaded plug 35 is opened, the molecular sieve desiccant 38 can be replenished into the drying chamber 31 through the feed inlet 34.

[0026] An electromagnetic valve a111 is also installed inside the air inlet pipe 11, and an electromagnetic valve b121 is installed inside the air exchange pipe 12. Among them, when the humidity sensor b26 detects that the air inside the cargo transportation box 10 is relatively humid, the humidity sensor b26 transmits an electrical signal to the controller 25, and the controller 25 controls the electromagnetic valve a111 and the electromagnetic valve b121 to open, so as to open the channels inside the air inlet pipe 11 and the air exchange pipe 12, facilitating the replacement of the gas inside the cargo transportation box 10. When it is not necessary to replace the gas inside the cargo transportation box 10, the electromagnetic valve a111 and the electromagnetic valve b121 are in a closed state, thus preventing the humid air from entering the cargo transportation box 10 from the inside of the air inlet pipe 11 and the air exchange pipe 12.

[0027] In this embodiment, the working principle of the device is as follows: When transporting goods in humid weather (especially when international trade goods are transported by sea), if the humidity sensor b26 inside the cargo transportation box 10 detects that the air humidity inside the cargo transportation box 10 is relatively high, the negative pressure fan 22 can be started to exchange the air inside the cargo transportation box 10.

[0028] When exchanging the air inside the cargo transportation box 10, the heating wire 23 is started to heat the air entering the air inlet pipe 11. In cooperation with the provided molecular sieve desiccant 38, dry air can enter the cargo transportation box 10, thereby exchanging the humid air inside the cargo transportation box 10, and then improving the humid environment inside the cargo transportation box 10 and enhancing the safety during the cargo transportation process.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
