The invention discloses a subway screen door header case seasonal conversion air valve. The subway screen door header case seasonal conversion air valve comprises a frame body, a first connecting rod,a second connecting rod, a third connecting rod and a plurality of blades, wherein the first connecting rod, the second connecting rod and the third connecting rod are arranged in a mutually spaced mode; the first connecting rod, the second connecting rod and the third connecting rod are rotatably and horizontally arranged on the frame body; the blades are fixedly arranged on the first connectingrod, the second connecting rod and the third connecting rod; the first connecting rod is fixedly provided with a rotating piece and a first wheel body, the rotating piece is used for driving the first connecting rod to rotate, the second connecting rod and the third connecting rod are provided with a second wheel body and a third wheel body correspondingly, the second wheel body is engaged with the first wheel body, and the third wheel body is engaged with the second wheel body; and the first connecting rod, the second connecting rod and the third connecting rod rotate and drive the blades tobe opened or closed. In the subway screen door header case seasonal conversion air valve, the rotating piece rotates to drive the first connecting rod, the second connecting rod and the third connecting rod to rotate, thus the blades arranged on the connecting rods are rotated to complete the task of opening and closing the blades, and the ventilation and closing functions of the subway screen door header case seasonal conversion air valve can be achieved flexibly.
Description
Technical field [0001] The invention relates to the field of subway ventilation, in particular to a seasonal switching air valve for a top box of a subway screen door. Background technique [0002] The structure above the subway screen door is generally kept sealed to prevent the piston wind generated when the train enters the station from entering the platform area, which affects the temperature and wind in the platform area and cannot be flexibly opened or closed. The temperature adjustment of the platform area can only rely on a large number of cooling or heating equipment, which generates a large amount of energy consumption. Summary of the invention [0003] The embodiment of the present invention provides a seasonal switching air valve for the top box of a subway screen door, which includes a frame, a first connecting rod, a second connecting rod, and a third connecting rod arranged at intervals, and a plurality of blades. The first link, the second link and the third link ...
