Basement ventilation shaft

The utility model discloses a basement ventilation shaft. The utility model relates to the field of building design, the problems that an existing basement lighting ventilation shaft achieves the ventilation effect only through gaps of rainproof shutters; the ventilation requirement is high; in order to solve the problem that in summer with strong illumination and high temperature, the ventilationeffect cannot well meet the requirement, the technical scheme is characterized in that driving air cylinders are arranged on the opposite inner side walls of a well wall, horizontal transmission rodsare coaxially fixed to pistons of the two driving air cylinders, and the transmission rods are driven by the driving air cylinders to move in the length direction of the well wall; and a rotating assembly is arranged on the transmission rod, and the rotating assembly controls the cover plate to ascend and descend through a driving air cylinder, so that the advantage of a better ventilation effectis achieved. 本实用新型公开了一种地下室
