Technical Field

The invention relates to the technical field of cold chain transportation equipment, in particular to a refrigerator car.

Background

The global refrigerated goods transportation usually adopts refrigerated vehicles, railway refrigerated vehicles and the like, and the refrigerated vehicles are flexible and suitable for short-distance refrigerated transportation; the railway refrigerator car relies on the advantages of railways, has obvious advantages for refrigeration transportation in long distance and remote areas, and is low in energy consumption and good in economical efficiency.

The existing railway mechanical refrigerator car is provided with a trailer refrigerating unit, and is provided with a metal oil tank to provide power for the refrigerating unit, so that the temperature control requirement in a tank at-29-30 ℃ can be realized. The capacity of the oil tank of the railway mechanical refrigerator car is extremely large, more than one thousand liters can be achieved, no oil can be added in the midway, oil can be added once a month even in some countries, and the operation and management are convenient. The mechanical refrigerator car for the railway is provided with two side doors, and meets the cargo loading and unloading requirements of stations along the railway. However, due to the railway track route, the railway mechanical refrigerator car cannot be driven to the field as a refrigerator car so as to realize the preposition of the refrigeration storage house, and the railway mechanical refrigerator car is transferred to each refrigeration storage house or a fresh food market from a railway station yard so as to solve the problem of the last kilometer. Therefore, the problem of cold chain 'chain breakage' exists in the transportation of the railway mechanical refrigerator car, the quality of goods is easily reduced and damaged due to secondary loading and unloading, and the 'door-to-door' transportation cannot be realized. In addition, due to the complex structure, high manufacturing cost and long manufacturing period of the railway mechanical refrigerator car, economically undeveloped countries such as southeast Asia and Africa, such as Bengal and Nigeria, are turning to find other more economic railway refrigerator cars.

After the refrigerated goods are shipped to ports of various countries by the refrigerated ships, the refrigerated containers for sea transportation can be installed on a railway container flat car for long-distance railway transportation. On a refrigerated vessel, a sea chest refrigeration unit of a marine refrigerated container is refrigerated by the concentrated power supply on the vessel. After the marine fridge arrives at a port, the refrigerating unit is shut down, then the marine fridge is transferred to a railway container flat car, and then the railway generator car is connected with the railway generator car to supply power for the marine fridge. After arriving at a railway station, the fresh food is transported to each refrigeration house or fresh food market by an automobile. By adopting a refrigerated truck mode of 'sea transport refrigerated storage box + railway container flat car', although the problem of secondary loading and unloading of a station yard is avoided, the problem of 'chain breakage' of a cold chain still exists in the process of transferring the sea-to-iron and the iron-to-public, and the problem of coordination and synchronization of the railway generator cars is brought because external power supply equipment is required.

On the land, some refrigerated goods are transported by railway in a refrigerated truck mode of 'land transportation refrigerated container + railway container flat car', the land transportation refrigerated container in the railway refrigerated transportation mode is provided with a trailer refrigerating unit or a T-shaped refrigerating unit, and an oil tank is arranged at the end part of the refrigerated container, so that power can be provided for the refrigerating unit, long-distance railway transportation can be realized, and the cold chain is directly connected with 'continuous chain' and 'door-to-door'. However, all the land-based and sea-based refrigerated containers for highway and railway combined transportation at present adopt an end cargo access mode, and for customers who need to unload cargos in a midway railway station, the rear-end door structure cannot meet the requirements, and only when the box body is disassembled from a railway container flat car and lifted to the ground, a forklift can enter the operation. Therefore, the refrigerated truck models of "land transportation refrigerated container + railway container flatcar" and "sea transportation refrigerated container + railway container flatcar" cannot meet the customer requirements in the yard cargo handling.

For high-end refrigerated goods, such as fish, shrimp, shellfish and other aquatic seafood, the requirements on temperature and quality of refrigerated transportation are extremely high, the lowest temperature control in the existing refrigerated truck and railway refrigerated truck box is-29 ℃, although the refrigerated transportation function of general aquatic seafood can be met, during the transportation process, frozen meat flow 'blood water' often occurs, frozen shrimps have the problem of nutrient loss such as 'blackheads', the freshness of food materials is greatly reduced, and the strict requirements of people in modern society on the quality of the high-end refrigerated goods food materials can not be met. The reality proves that the goods can be quickly frozen in a low-temperature environment of-40 ℃, and the taste of the goods is closer to the original freshness of food materials. At present, only a sea box refrigerating unit can reach the minimum temperature control temperature of-40 ℃ in global refrigeration and transportation, a trailer unit and a T-shaped unit are both used as land units, and the minimum temperature control temperature is only-29 ℃.

In view of the economic nature that the railway refrigerator car possesses long distance transport and the eager demand of each country in the world to the railway refrigerator car, seek a novel refrigerator car, this refrigerator car has both solved the cold chain "broken chain" that existing railway refrigerator car exists, the secondary loading and unloading takes place the goods loss, can't realize "door to door" transportation, the problem that structure is complicated and with high costs, the unable direct loading and unloading of railway station goods that has solved the refrigerator car that refrigerated container and railway container flatcar combination formed, realize-40 ℃ of extremely low temperature simultaneously for the first time, effectively guarantee that the original freshness of refrigerated goods taste is closer to the edible material, promoted people and experienced the taste of high-end refrigerated goods. The existing refrigerated goods railway transportation mode is as follows: railway mechanical refrigerated vehicles, land transportation refrigerated containers and railway container flat cars, sea transportation refrigerated containers and railway container flat cars.

The prior art can not solve the problems of cold chain 'chain breakage' and cargo loss caused by secondary loading and unloading of the railway refrigerator car, the 'door-to-door' transportation, complex structure and high cost can not be realized, the problem that the railway station goods can not be directly loaded and unloaded in the refrigerator car formed by combining the refrigerated container and the railway container flat car can not be solved, and the problem that the taste of the refrigerated goods is closer to the original freshness of food materials can not be realized by extremely low temperature control of-40 ℃.
