When replacing and cleaning the louver grille exhaust outlet 4, the handle 11 can be pulled to deform the clamping plate 10 to disassemble and clean the louver grille exhaust outlet 4, and then the second fixed frame 503 and the first fixed frame 501 inside the filter box 2 can be taken out, so that the activated carbon and the filter element 502 can be replaced conveniently, avoiding the problem that most of the existing railway locomotive ventilation structures have a relatively single way of filtering the air, resulting in incomplete air filtering, and inconvenient replacement of the filter structure and cleaning of the exhaust outlet, thus affecting the use effect.

As a technical optimization solution of the present invention, a sealing plug 7 is provided on the front side of the second fixing frame 503 , and the surface of the sealing plug 7 is in close contact with the inside of the front side mesh 504 .

In this embodiment, the sealing plug 7 is pulled to separate from the interior of the front gauze 504 , and the second fixing frame 503 can be opened at this time, thereby achieving the effect of facilitating the opening of the second fixing frame 503 .

As a technical optimization solution of the utility model, the surface of the louver grille exhaust outlet 4 contacts the inner wall of the filter box 2, and the four corners of the rear side of the louver grille exhaust outlet 4 are fixedly connected with top columns 12, and the rear side of the top column 12 contacts the front side of the second fixed frame 503, and the rear side of the second fixed frame 503 contacts the front side of the first fixed frame 501.

In this embodiment: by connecting the louver grille exhaust outlet 4 to the filter box 2, the top column 12 contacts the front side of the second fixed frame 503, and the second fixed frame 503 and the first fixed frame 501 are pressed against the partition 6 in turn to contact the partition 6, thereby achieving the effect of limiting the first fixed frame 501 and the second fixed frame 503.

As a technical optimization solution of the present invention, ultraviolet lamps 13 are fixedly connected between the two top pillars 12 and the opposite sides of the two bottom pillars 12 .

In this embodiment, the air can be disinfected by controlling the operation of the ultraviolet lamp 13, thereby achieving the effect of convenient air disinfection.

As a technical optimization solution of the present invention, a partition 6 is fixedly connected to the inner wall of the filter box 2 , and there are several partitions 6 . The rear side of the first fixed frame 501 is in contact with the front side of the partition 6 .

In this embodiment: by controlling the operation of the fan 8, the fan 8 can suck in the external air of the railway locomotive, and then separate it through the partition 6, so that the air is quickly dispersed and evenly enters the filter element 502 for filtration, thereby achieving the effect of facilitating the uniform entry of air into the filter element 502.

As a technical optimization solution of the utility model, both sides of the front side of the louver grille exhaust outlet 4 are fixedly connected with a fixing plate 3, the rear side of the fixing plate 3 is fixedly connected with a clamping plate 10, the surfaces of the fixing plate 3 and the clamping plate 10 are in contact with the surface of the filter box 2, and a buckle groove 15 is opened inside the fixing plate 3.

In this embodiment: by moving the fixing plate 3 and the clamping plate 10 to contact with the surface of the filter box 2, the clamping plate 10 and the clamping block 14 are in contact and squeezed, causing the clamping plate 10 to deform, thereby causing the clamping block 14 to move to the inside of the through groove 9. At this time, the clamping plate 10, the fixing plate 3 and the louver grille exhaust port 4 can be limited, thereby achieving the effect of limiting the clamping plate 10.

As a technical optimization solution of the present invention, the material of the card board 10 is a highly elastic plastic, and a handle 11 is fixedly connected to the surface of the card board 10 .

In this embodiment, since the material of the card board 10 is a highly elastic plastic, when the handle 11 is pulled, the card board 10 can be deformed, thereby achieving the effect of allowing the card board 10 to be deformed.

Working principle: First, pull the sealing plug 7 to disengage the sealing plug 7 from the inside of the front side screen 504. At this time, the second fixed frame 503 can be opened, and then the activated carbon can be poured into the second fixed frame 503. At this time, the two screens 504 can limit the activated carbon inside the second fixed frame 503. Then, the first fixed frame 501, the filter element 502, the second fixed frame 503 and the activated carbon are placed in the filter box 2 in sequence. At this time, the holding buckle slot 15 moves the fixing plate 3 and the card plate 10 to contact the surface of the filter box 2. At this time, the card plate 10 is in contact with the card block 14 and squeezed, so that the card plate 10 is deformed, so that the card block 14 moves to the inside of the through groove 9. At this time, the card plate 10, the fixing plate 3 and the louver grille exhaust port 4 can be limited. Then, after the ventilation pipe 1 and the filter box 2 are installed to the internal installation position of the railway locomotive, the fan 8 and the ultraviolet lamp 13 are controlled to work. The fan 8 can work to inhale the air outside the railway locomotive, and then The air is separated by the partition 6 so that it can be quickly dispersed and then evenly enters the filter element 502 for preliminary filtration and then filtered twice by the activated carbon. Finally, it is disinfected by the ultraviolet lamp 13 and discharged from the louver grille exhaust port 4 to the interior of the railway locomotive. When it is necessary to replace the filter element 502 and the activated carbon and clean the louver grille exhaust port 4, the palm of the hand leans against the fixed plate 3 and then the finger pulls the handle 11 to deform the card plate 10 and separate it from the card block 14, so that the louver grille exhaust port 4 can be disassembled and cleaned. Then the second fixed frame 503 and the first fixed frame 501 inside the filter box 2 can be taken out, so that the activated carbon and the filter element 502 can be replaced conveniently, thereby avoiding the problem that the air filtering method in most existing railway locomotive ventilation structures is relatively single, resulting in incomplete air filtering and inconvenient replacement of the filter structure and cleaning of the exhaust port, thus affecting the use effect.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
