Embodiment Construction

[0032] The following will be combined with Figure 1 to Figure 8 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on th...

Abstract

The invention relates to the technical field of railway vehicles, in particular to a mechanical waste discharge device of a railway vehicle. The device comprises a shell; silencing cotton adheres to the periphery of the inner side wall of the shell;a supporting base is installed in the center of the inner wall of the bottom of the shell through bolts;and baffles are welded to the inner walls of the two sides, close to the supporting base, of the shell. The device has the beneficial effects that the jackinggroove enables the supporting baseto be better attached to the outer side wall of afan; the working stability of the fan is improved; the jacking seat has a certain damping effect on the fan under the action of the spring; a good protection effect is achieved on the fan; the service lifeof the fan is further prolonged;the sound insulation lining barrel enables the noise generated by the fact that air flow impacts the air channel to be reduced when the fan sucks air through the air inlet, the silencing cotton further reduces the noise generated when the fan works, a quiet environment is provided for passengers, and the comfort of the passengers when the passengers take the rail vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a mechanical waste discharge device for rail vehicles. Background technique [0002] In rail vehicles, each car is generally equipped with one or two air-conditioning units, and each air-conditioning unit adopts a unit structure or a split structure; The air outlet is connected, the air supply duct and the air supply outlet are used to supply air to the cabin, and the return air in the cabin is sent back to the air conditioner through the return air duct for recycling; the air conditioning unit communicates with the outside of the vehicle through the fresh air outlet to Deliver fresh air in the compartment to ensure the freshness of the air in the compartment. While delivering fresh air to the compartment, part of the exhaust gas is discharged out of the compartment through the exhaust device to ensure a certain positive pressure in the compartment to improve the comfort in...
