[0033] As shown in the accompanying drawings, Figure 4 The inside of the installation shell 1 is provided with a soundproof assembly, the soundproof assembly comprising a mounting ring 14 fixedly connected to the inside of the installation shell 1, a plurality of columnar grooves 15 opened in the lower surface of the mounting ring 14, a spring 16 fixedly connected to the inside of the columnar groove 15, a rubber pad 17 provided at one end of the spring 16, a protective shell 18 provided on the upper surface of the rubber pad 17, the protective shell 18 slidably connected to the inside of the columnar groove 15, a plurality of threaded studs 19 fixedly connected to the lower surface of the mounting ring 14, and nuts 20 threadedly connected to the outside of the threaded studs 19, the columnar groove 15 facilitating the installation of the spring 16, the rubber pad 17 facilitating the soundproof effect, reducing the noise generated by the collision between the fixing block 21 and the mounting ring 14, and the threaded studs 19 and the nuts 20 facilitating the installation of the fan 2.

[0034] As shown in the accompanying drawings, Figure 6 The outside of the fan 2 is fixedly connected with a plurality of fixing blocks 21, the middle part of the fixing block 21 is provided with a through groove 22, the threaded stud 19 penetrates through the inside of the through groove 22, and the connection of the fixing block 21 facilitates the installation of the fan 2.

[0035] As shown in the accompanying drawings, Figure 2 The lower surface of the installation shell 1 is fixedly connected with a dirt collecting plate 23, and one end of the exhaust pipe 5 is fixedly connected with a protective net 24, the dirt collecting plate 23 is conducive to collecting the dust cleaned by the dust cleaning brushes 13, preventing the dust from directly falling on the bottom of the carriage, and the protective net 24 is helpful to reduce the foreign matters falling into the inside of the exhaust pipe 5.

[0036] Working principle: when the high-speed train carriage produces smoke, the smoke detector 3 will detect the smoke first and produce an alarm, and the switch controller 4 will start the fan 2 after receiving the signal of the smoke detector 3. When the fan 2 is opened, the smoke is sucked in through the hole in the lower surface of the installation shell 1. The smoke will pass through the filter screen 6, and the filter screen 6 will intercept large-particle impurities and dust. The filtered smoke will reach the inside of the exhaust pipe 5 under the action of suction, and will be discharged through the exhaust pipe 5 connected to the outside. When the filter screen 6 intercepts a certain amount of dust and needs to be cleaned, the fan 2 is turned off and the motor 7 is turned on, so that the output end of the motor 7 drives one of the first bevel gears 8 to rotate. The first bevel gear 8 drives the second bevel gear 12 to rotate through the meshing of the first bevel gear 8 and the second bevel gear 12. The second bevel gear 12 drives the rotating rod 11 to rotate under the connection of the other first bevel gear 8, so as to drive the shaft 9 to rotate, and the shaft 9 drives the two dust cleaning brushes 13 at one end to revolve, so as to facilitate the dust cleaning brushes 13 to brush on both sides of the filter screen 6, which is beneficial to reduce the phenomenon that the smoke is discharged slowly due to the blockage of the filter screen 6.

[0037] When the fan 2 is in use, the fixed block 21 and the mounting ring 14 will collide due to vibration. When the fan 2 collides, the rubber pad 17 will be contacted first, and the rubber pad 17 will be retracted and pressed to the spring 16, so that the spring 16 generates elastic force under pressure. Then the elastic force releases to push the rubber pad 17, so that the rubber pad 17 pushes the fixed block 21. The elastic force of the rubber pad 17 and the spring 16 and the noise absorption force facilitate the reduction of the phenomenon that noise is generated due to the collision between the fan 2 and the inner wall of the pipeline after installation.

[0038] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
