Therefore, it should not be construed as a limitation on the present invention.

In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection or a connectable connection. Detachable connection, or integral connection; may be mechanical connection or electrical connection; may be direct connection, or indirect connection through an intermediate medium, or internal communication between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

The present embodiment will be described in detail below in conjunction with the accompanying drawings:

This embodiment provides an all-round cleaning device for the underbody of an EMU. Please refer to Figures 1-2 in the accompanying drawings in the description.

As shown in Figure 1-2, an all-round cleaning device for the underbody of an EMU includes a soft suction pipe 1 and a dual-axis drive motor 2. One end of the dual-axis drive motor 2 drives the reducer 3 to rotate, and the output shaft of the reducer 3 rotates. It is fixedly connected with one end of the rubber soft column 16 in the soft suction pipe 1, and the other end of the biaxial drive motor 2 is located in the bellows 4, and directly drives the turbine blades 5 in the bellows 4 to rotate. The pipe interface 6 is communicated through the hollow handle pipe 7, the pipe interface 6 is fixedly connected with the end of the reducer 3, and is penetrated by the output shaft of the reducer 3, and the exhaust end of the bellows 4 is screwed with a detachable filter mesh cylinder 8 , the side wall of the soft rubber column 16 is provided with a helical blade 9 , and the helical blade 9 extends from the pipe interface 6 to the outside of the other end of the soft suction pipe 1 .

In order to facilitate hand-holding, a rechargeable battery 10 is provided on the outer walls of the biaxial drive motor 2 and the reducer 3 , and the rechargeable battery 10 supplies power to the drive motor 2 through a control switch 11 provided outside the handle pipe 7 .

In order to improve the filtering effect, a filter cloth bag 12 covering the exhaust end of the bellows 4 is arranged in the filter mesh cylinder 8 .

In order to improve the cleaning effect, there is a gap between the edge of the spiral blade 9 and the side wall of the soft suction tube 1 , and the edge of the spiral blade 9 is evenly fixed with bristles 13 in contact with the inner wall of the soft suction tube 1 .
