Abstract

The invention provides a fan for an auxiliary filter cabinet of an electric locomotive and the electric locomotive. The fan comprises a machine shell, a motor, a guide blade ring, and an impeller, wherein the machine shell is provided with an air inlet, an air outlet, and a cavity communicated with the air inlet and the air outlet, the motor is provided with an output shaft and is fixed at the end, close to the air inlet, of the cavity, the guide blade ring is sealed at the end, close to the air outlet, of the machine shell in a rotating mode, the output shaft penetrates through the guide blade ring, and the impeller is fixed at the end, far away from the machine shell, of the guide blade ring in a sealing mode and is further fixedly connected with the output shaft. The motor rotates so as to enable cooling gas to be absorbed in the cavity through the air inlet. The cooling gas is driven by the guide blade ring and the impeller to be exhausted from the air outlet. By the adoption of the technical scheme, the fan can be adjusted in multiple directions on the condition that the air direction of the fan is not changed, so that the requirements of the locomotive for the air direction of the auxiliary filter cabinet in different working conditions can be met.

Description

technical field [0001] The invention relates to mechanical structure technology, in particular to a fan used for an auxiliary filter cabinet of an electric locomotive and an electric locomotive. Background technique [0002] The HXD2C locomotive is equipped with an auxiliary filter cabinet to filter various signals on the locomotive. [0003] Figure 1a It is a schematic diagram of the front view of the structure of the auxiliary filter cabinet, Figure 1b for Figure 1a side view. see Figure 1a with Figure 1b , taking the direction shown in the figure as the reference direction. see Figure 1a , the auxiliary filtering cabinet is in the shape of a cube as a whole, and the internal space of the auxiliary filtering cabinet can be roughly divided into an upper space, a middle space and a lower space. Among them, the fan 1 is installed in the upper space; the left side of the middle space is the installation space of the auxiliary transformer 2, and the right side is the ...
