Its installation form is mostly hoisting, and multiple bolts of the M16X80 model are used in cooperation with lifting lugs for hoisting operations.

[0003] At present, a certain high-temperature phenomenon will occur inside the under-car power cabinet for rail transit due to the operation of the battery. However, the power cabinet does not have good temperature adjustment equipment inside. The working efficiency of the power cabinet will decrease in a certain temperature environment. The prior art also uses the ventilation and heat dissipation operation of a cooling fan to cool down. However, the long-term operation of the cooling fan will cause the problem of power loss, and it cannot reasonably utilize the power of the battery, nor can it utilize the airflow generated when the rail vehicle moves for heat dissipation operations. Therefore, it is urgent to design an adjustable power cabinet to solve the above problems. Content of the Utility Model
