Method for detecting vehicle air duct design by using ERC bow net track

Abstract

The invention discloses a method for detecting a vehicle air duct design by using an ERC bow net track and relates to the technical field of vehicle air duct design detection by using the bow net track. The method comprises the following steps: the air duct is made of glass fiber reinforced plastics, an air delivery duct main body is a three layer structure; a main air duct is divided into two groups of branch air ducts at the position of an observation tower through a transition air duct, the turning corner of the transition air duct adopts circular arc transition, and guide plates are arranged at the turning-in position and the turning-out position of the transition air duct; a crew room and a private room adopt a form of downward air outlets at the two sides of a top plate, and a windward plate is additionally arranged at each air outlet; a conference room adopts hidden air outlets at two sides of the top plate, and the air outlets are arranged between a side top plate and a middletop plate; air outlets of a detection chamber are arranged in the decorative strips at the two sides, and a perforated aluminum plate is arranged between the decorative strips and a side wall to serveas an air outlet. According to the invention, the air duct is made of a fire-proof material, and the transition air duct is adopted at the position of the observation tower, so that the loss of air quantity in each room is effectively reduced; the air outlets adopt the forms of downward air outlets and hidden air outlets at the two sides of the top plate and the windward plates are arranged, thereby effectively avoiding the influence on the comfort degree caused by the direct blowing of cold air to a human body.

Description

technical field [0001] The invention relates to the technical field of air duct design for a pantograph-catenary track detection vehicle, in particular to an air duct design method for an ERC pantograph-catenary track detection vehicle. Background technique [0002] In order to provide a comfortable working environment for the staff in the pantograph-catenary inspection vehicle, the pantograph-catenary inspection vehicle of the Ethiopian Railway Corporation (ERC) is equipped with an air-conditioning unit, and the air is delivered to each work room in the vehicle through the roof air duct, thus playing a role The functions of cooling, heating and filtering air provide pleasant temperature, humidity and clean air for the staff in the car. [0003] Since the roof of the ERC pantograph-catenary track detection vehicle is equipped with catenary detection equipment, in order to facilitate the observation of the detection equipment on the roof, an observation tower is installed in ...

Problems solved by technology

[0004] In order to solve the technical problems of the existing ERC pantograph-catenary track inspection vehicle that the air ducts are separated and combined at the observation tower, which easily leads to insufficient air supply in each room, and the form of air blowing directly from the top plate seriously affects the comfort of the human body. The invention provides a method for designing the air duct of an ERC pantograph-catenary track detection vehicle
