Description

Technical Field

[0001] The present invention relates to the technical field of fresh-keeping containers, and in particular to a fresh-keeping container for rail vehicles. Background Art

[0002] With the development of economy, the circulation frequency of goods is increasing rapidly, so the demand for materials is increasing. Rail transportation has an important position in the field of logistics due to its high accuracy and continuity, almost unaffected by climate, and can operate regularly and accurately throughout the year. It should be noted that when transporting some fresh vegetables or meat, containers (i.e. containers) are needed for transportation, and refrigeration equipment is needed to cool the containers to keep the goods fresh.

[0003] Generally, a container is composed of a cargo warehouse and a refrigeration warehouse. The goods are placed in the cargo warehouse. Various refrigeration equipment is installed in the refrigeration warehouse, and a filter plate is added on the outside to protect the refrigeration equipment to ensure its safety. However, during the transportation of the container, due to the large span and long time of rail transportation, the container is very likely to be in a high temperature environment for a long time, while the interior of the container requires a lower temperature so that the goods can be kept fresh. Therefore, if it is in a high temperature environment for a long time, it is very easy to cause a large temperature difference between the inside and the outside, so that the refrigeration equipment needs to consume a lot of energy to maintain the temperature inside the container, which greatly increases the energy consumption of the container and even causes the refrigeration equipment to burn out. This not only easily damages the container, but also seriously causes the entire container cargo to be scrapped, causing great economic losses. Summary of the invention

It should be noted that, in the embodiment of the present invention, when the lower pressing frame 608 moves, the plurality of limiting holes 612 move on the plurality of limiting frames 613, so that the lower pressing frame 608 is restricted to move only vertically, and thus the lower pressing frame 608 can smoothly squeeze the plurality of arc-shaped push plates 602.

[0040] In summary, the working principle of a fresh-keeping container for rail vehicles provided by an embodiment of the present invention is: When the container body 1 is transported by rail, rainwater is collected by two water collecting covers 408, or water can be directly added to the water collecting covers 408, so that the water flushes the sealing plate 411, and the sealing plate 411 rotates on the support shaft 413, and the rotary torsion spring 414 is stressed, and the sealing plate 411 rotates and opens, so that water can enter the water storage bag 404 through the water collecting pipe 409, and the water filling work of the water storage bag 404 is completed, so that the container body 1 can also be replenished with water during the driving process, which effectively saves resources; in addition, when the weather is too hot, the water storage bag 404 is heated and expanded, and then Push the trigger plate 415 to move, and the trigger plate 415 turns on the delay switch 407. At this time, the water pump 405 pumps the water in the water storage bag 404, and enters the spraying frame 402 through the transmission water pipe 406, and then sprays it through multiple spraying heads 403, so as to physically cool the outside of the container body 1, and further cool the sprayed water with the help of the airflow generated by the rail transportation, so as to further take away the heat of the container body 1, effectively ensuring the reduction of the temperature outside the container body 1, and avoiding the problem of excessive temperature causing a large temperature difference between the inside and outside of the container body 1, which causes excessive energy consumption of the container body 1; Furthermore, during the rail transportation of the container body 1, due to the high speed and stable speed, the airflow can continuously blow the multiple power sheets 508, thereby causing the multiple power sheets 508 to continuously drive the driving column 507 to rotate, and the driving column 507 drives the power block 510 to move through the power slot 509, thereby driving the lifting slide 505 to slide, and the lifting slide 505 slides in the lifting frame 504, and drives the lifting plate 503 to move, and the movement of the lifting plate 503 drives the spraying frame 402 to move, and the movement of the spraying frame 402 drives the cleaning frame 501 to move, and the cleaning frame 501 cleans the filter plate 7 through the dense cleaning bristles 502 to ensure the unobstructed flow of the filter plate 7, so that the equipment in the refrigeration warehouse 3 can dissipate heat normally, thereby ensuring the refrigeration effect of the container body 1, and at the same time, when the driving column 507 rotates one circle, it can drive the lifting slide 505 to slide vertically up and down once, which can further dissipate heat to the outside of the container body 1, and ensure the cleaning effect of the filter plate 7, thereby ensuring the continuous energy-saving operation of the container body 1; Furthermore, after the cargo is loaded, the threaded column 610 is driven to rotate by rotating the handle 611, and the threaded column 610 rotates in the threaded hole 609, thereby driving the lower pressure frame 608 to move, and the lower pressure frame 608 moves and squeezes the four arc-shaped push plates 602 to move synchronously, and the arc-shaped push plates 602 move and drive the installation cross bar 604 to move through the straightening plate 603, and the installation cross bar 604 drives multiple adjustment squeeze bars 605 to straighten the cargo, so that the cargo can be placed in the center position of the container body 1, and the air circulation around the cargo is guaranteed, thereby ensuring the safety of the cargo, and the position of the adjustment squeeze bar 605 can be adjusted according to the situation of the cargo to ensure the straightening effect of the cargo, and at the same time, the cargo can be clamped around after straightening to ensure the stability of the cargo during transportation, avoid the cargo from falling due to vibration or other unexpected reasons, and further ensure the safety of the cargo.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
