Problems solved by technology

[0002] At present, the domestic high-speed vehicle or locomotive ventilator air intake filter is installed on the surface of the vehicle or locomotive. When the vehicle or locomotive is running at high speed, the air intake surface at the ventilation device is in a negative pressure area. Under the action of the same ventilator, the higher the speed , the greater the negative pressure effect of the air inlet surface at the ventilation device, the lower or even no air intake of the fan will affect the work of the ventilation and cooling components in the locomotive

Abstract

The invention discloses a self-adjustment ventilation device for high-speed rail transit and a locomotive. The self-adjustment ventilation device comprises a barrel with one open end. The open end of the barrel is covered with a cover plate, and the barrel and the cover plate form an installation space. The two opposite side edges of the barrel and the cover plate are all provided with a plurality of air inlets. A spoiler capable of moving in the vertical direction in the installation space is installed in the barrel. Through the self-adjustment ventilation device for the high-speed rail transit and the locomotive, the problems that air cannot enter the ventilation device or little air enters the ventilation device due to negative pressure generated near the surface of a vehicle body during traveling of a high-speed vehicle or the locomotive are solved, and effective air inlet quantity of the ventilation device can be adjusted automatically according to the operation speed of the vehicle or the locomotive.

Description

technical field [0001] The invention relates to the technical field of rail transit locomotives, in particular to a self-regulating ventilation device for high-speed rail transit and a locomotive. Background technique [0002] At present, the domestic high-speed vehicle or locomotive ventilator air intake filter is installed on the surface of the vehicle or locomotive. When the vehicle or locomotive is running at high speed, the air intake surface at the ventilation device is in a negative pressure area. Under the action of the same ventilator, the higher the speed , the greater the negative pressure effect of the air inlet surface at the ventilation device, the lower the air intake of the fan or even no air intake, which will affect the work of the ventilator cooling components in the locomotive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-regulating ventilation device and a locomotive for high-speed ...
