[0013] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0014] Please see Figure 1-3The present invention provides a technical solution: a rainwater separator for rail vehicles, comprising a frame 1, wherein a first filter layer 2 and a second filter layer 3 are sequentially arranged in the frame 1 along the air inlet direction; the first filter layer 2 comprises a hollow rectangular mounting frame 21 and a first filter element 22 installed in the mounting frame 21; the second filter layer 3 comprises a top plate 31, a bottom plate 32 and a plurality of second filter elements and a plurality of dust collection elements disposed between the top plate 31 and the bottom plate 32; a dust collection box 4 is provided at the bottom of the frame 1 for dust collection; mounting grooves 36 corresponding to the second filter elements and dust collection elements are provided on the top plate 31 and the bottom plate 32; and a through groove 13 corresponding to the dust collection elements is provided at the bottom of the bottom plate 32 for connecting the dust collection elements and the collection box 4. The first filter layer 2 and the second filter layer 3 are used to filter rainwater and impurities, so that the humidity and other properties of the air entering the carriage through this structure meet the standards. The first filter element 22 is used for coarse filtration to prevent larger foreign objects from entering. When rainwater and small dust particles pass through the first filter layer 2, the air and rainwater and dust are separated by the second filter element and the dust collector, making the air entering the carriage cleaner and drier. The rainwater and dust entering the dust collector will slide down into the collection box 4 through the channel 13.

[0015] The second filter element includes several fan-shaped diverter pipes 33 arranged in a straight line. The dust collection element includes a first dust collection pipe 34 and a second dust collection pipe 35. The first dust collection pipe 34 is located behind both sides of the fan-shaped diverter pipes 33 and is staggered with the fan-shaped diverter pipes 33. The tail of the fan-shaped diverter pipe 33 is integrally formed with a first guide plate 331. The second dust collection pipe 35 is located behind the first guide plate 331. Both the first dust collection pipe 34 and the second dust collection pipe 35 have openings facing the air inlet. The openings of the first dust collection pipe 34 and the openings of the second dust collection pipe 35 are integrally formed with inwardly folded edges. The tail of the first dust collection pipe 34 is integrally formed with a second guide plate 341. The second dust collection pipe 35 is located on the left and right sides of the second guide plate 341 and is staggered with the first dust collection pipe 34. External air undergoes a rapid change in acceleration and direction at the fan-shaped diversion pipe 33, generating centrifugal force. This causes dust and water droplets, which contain high momentum, to enter the first dust collection pipe 34 and the second dust collection pipe 35. Due to their own weight, the water droplets and dust fall and are discharged into the collection box 4. The first guide plate 331 and the second guide plate 341 act as guides, allowing water droplets and dust to enter the first dust collection pipe 34 and the second dust collection pipe 35 through the opening along with the airflow. The outward-folded edges at the openings effectively prevent water droplets and dust from leaving the first dust collection pipe 34 or the second dust collection pipe 35 under the influence of the airflow.

[0016] The frame 1 has U-shaped plates 11 on both sides facing the air inlet, with the opening edges of the two U-shaped plates 11 facing each other. The mounting frame 21 is installed between the two U-shaped plates 11. An arc-shaped elastic plate 12 is provided on the side wall of the U-shaped plate 11. A handle 23 is provided on the top of the mounting frame 21. The mounting frame 21 is restricted and fixed by the U-shaped plate 11. The mounting frame 21 can be inserted into or pulled out of the U-shaped plate 11 by the handle 23, which is convenient and quick. After the mounting frame 21 is inserted into the U-shaped plate 11, the elastic plate 12 is squeezed and deformed, and at the same time, it generates elastic force on the mounting frame 21 to fix the mounting frame 21.

[0017] The collection box 4 has an observation port along its length, and a plug 41 is installed on the observation port. The collection box 4 has multiple overflow ports 42 facing the air inlet direction. After water and dust impurities enter the collection box 4, when the liquid level in the collection box 4 exceeds the overflow port 42, the water will be discharged from the overflow port 42 to the outside of the vehicle. The plug 41 is made of transparent material, which makes it easy to observe the dust impurities accumulated in the collection box 4 so as to clean them in time.

[0018] The first filter element 22 includes filter cotton 221 and a support net 222 disposed inside the filter cotton 221 for supporting the filter cotton 221; The filter cotton 221 performs coarse filtration of the outside air, blocking larger particulate impurities from entering. The support net 222 supports the filter cotton 221, preventing it from deforming or collapsing under the action of airflow, and ensuring that the filter cotton 221 always maintains an effective filtration area and shape.

[0019] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
