Abstract

The invention discloses a ventilation converting device. The ventilation converting device is arranged in a rail locomotive and comprises an outer casing, a rotating shaft, an air duct cover plate and a rotating rod, wherein the outer casing is provided with a first exhaust outlet which can be communicated with an air duct of a machine room and a second exhaust outlet which can be communicated with an air duct at the bottom of the rail locomotive; the rotating shaft is arranged in the outer casing and one end of the rotating shaft penetrates out of the outer casing; the axial direction of the rotating shaft is parallel to a plane where the first exhaust outlet is positioned and a plane where the second exhaust outlet is positioned; in addition, the rotating shaft can rotate around the axis of the rotating shaft; the air duct cover plate is fixed on the rotating shaft and can seal the first exhaust outlet and the second exhaust outlet; the rotating rod is fixed at the penetrating-out end through which the rotating shaft penetrates out of the outer casing; the rotating rod is driven to drive the rotating shaft to rotate, and the air duct cover plate can be switched for sealing and covering the first exhaust outlet or the second exhaust outlet. According to the ventilation converting device, the problems that the converting device in a ventilation duct is heavier in a narrow space of the machine room and the like are effectively solved. The invention also discloses the rail locomotive comprising the ventilation converting device.

Description

technical field

[0001] The invention relates to the technical field of rail transit locomotives, in particular to a ventilation conversion device. In addition, the present invention also relates to a rail vehicle comprising the above-mentioned ventilation switching device. Background technique

[0002] At present, the heat dissipation and ventilation of brake compressors in domestic electric locomotive machinery rooms usually use independent air ducts, and the heat dissipation of the compressors is relatively large, reaching 3.6kW. In summer, due to the high temperature in the mechanical room, the heat needs to be discharged outside the car to control the temperature inside the car; in winter, the temperature inside the car is low, and heat needs to be supplemented to increase the temperature, and the heat released by the recovery compressor is a kind of better way. The heat exhausted by the compressor is discharged through two channels: one is to discharge directly throug...
