The invention discloses a movable emergency direct current power cabinet, wherein a power cabinet body comprises a charging and feeding cabinet and a battery cabinet, vertical columns are arranged at four corners of the cabinet body, the charging and feeding cabinet is electrically connected with the battery cabinet, and multiple layers of battery devices are arranged in the battery cabinet. Each battery device comprises a battery supporting plate and battery installation grooves distributed in the battery supporting plate fixedly in a matrix mode. Supporting columns are arranged among adjacent vertical columns, and a movable device is arranged at the lower portion of the cabinet body. A hoisting ring is arranged at the top of the cabinet body, so that hoisting during transportation of the direct current power cabinet is facilitated. The movable device is arranged at the bottom of the cabinet body and replaces universal wheels directly arranged at the bottom of the power cabinet, therefore, unreliable rolling and easy damage caused by too-small wheels are avoided, and unsteady gravity of the cabinet body caused by too-large wheels is avoided. The battery supporting plate is reinforced by the supporting columns, and gravitational deformation possibly occurring during usage of the power cabinet is avoided.
