Double-tuyere cab air supply structure

Abstract

The invention provides a double-tuyere cab air supply structure which comprises a passenger room air duct, a transition air duct, a cab air supply unit, a cab air duct and an adjustable tuyere, the passenger room air duct is L-shaped on two sides of the end of a passenger room, one end of the passenger room air duct is arranged along two sides of the passenger room, and the other end of the passenger room air duct is transversely arranged along the end of a carriage and converges in the middle of the passenger room. A passenger room air supply outlet is arranged at the junction towards the cab side; The transition air duct comprises a soft air duct, wherein one end of the soft air duct is connected with the passenger room air supply outlet, and the other end of the soft air duct is connected with the cab air supply unit; the cab air duct is Y-shaped, one end of the cab air duct is connected with the cab air supply unit, the other end of the cab air duct is divided into two branches which respectively extend to areas above a main driver seat and an auxiliary driver seat, and adjustable air ports are connected below the branches; an inner cavity of the cab air duct is gradually enlarged towards the vehicle head direction, the two sides of the cab air duct are in sealed connection with the outer sides of two branches respectively, and the inner sides of the two branches are in sealed connection. Air flow is divided into two paths to be sent to the positions above a main driver seat and an auxiliary driver seat through a cab air duct branch, the comfort of a driver is improved, and the air volume adjusting range is widened.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle manufacturing and interior decoration, and in particular relates to an air supply structure for a driver's cab with double air outlets. Background technique [0002] As an important auxiliary part of the driver's cab, the air supply device for the driver's cab in rail vehicles is usually used to replace the air in the driver's room, and send warm or cold air through the air supply device to make the temperature and humidity in the driver's room better meet the comfort of the human body. sex. [0003] In urban railway projects, when the driver's cab is equipped with an air supply structure for the driver's cab, the air supply structure for the driver's cab is generally installed above the roof of the cab aisle, and an adjustable air outlet is directly set at the lower part of the connection between the roof and the cab air supply structure. The air supply to the driver's cab, on the one hand,...
