Abstract

The invention provides a totally-enclosed flow guide device for the pantograph area of a high-speed train. The device comprises a flow guide cover, two side wings are symmetrically arranged on the flow guide cover, the flow guide cover is arranged in a streamlined circular arch shape or a water drop shape, a lower arm frame hole and a pull rod hole are formed in the middle of the flow guide cover, a pantograph is arranged in the flow guide cover, the lower arm frame hole and the pull rod hole are respectively used for a lower arm frame and a pull rod of the pantograph to pass through; and the device also comprises two sets of driving devices, which are symmetrically arranged, the two sets of driving devices are connected with the two side wings correspondingly, and the driving devices are used for driving the side wings to open, close and rotate. The functions of the pantograph are not affected, the pantograph is completely closed during pantograph descending, impact of airflow with a base and a rod piece at the bottom of the pantograph and a pantograph area cavity is reduced during pantograph ascending, and therefore the purposes of reducing resistance and noise are achieved.

Description

technical field [0001] The invention relates to the technical field of high-speed trains, in particular to a fully enclosed diversion device for pantograph areas of high-speed trains. Background technique [0002] With the increase of the speed of high-speed trains, the aerodynamic effect has a greater impact on the stability and comfort of the train, and the problems of train aerodynamic resistance and aerodynamic noise have received special attention. The aerodynamic resistance and aerodynamic noise of high-speed trains mainly originate from the front and rear of the train, the bogie, the surface of the train body, and the pantograph. Among them, the pantograph is completely exposed to the air when the train is running at high speed. When the airflow passes through the pantograph area, the pantograph rod will generate a large number of vortex shedding, causing the vortices to mix with each other, making the airflow in this area very disturbed, resulting in Greater aerodyn...
