The invention relates to an elevator car airflow self-adaptive noise reduction ventilation device which comprises an air duct arranged on an elevator car wall, and a plurality of air deflectors are arranged in the air duct at intervals. A linkage rod is hinged to one side of each air guide plate, and two opposite electromagnets are arranged in the air duct; when the elevator car runs in the hoistway, all the air deflectors rotate with the rotating shaft as the center line under the action of airflow in the air channel, so that the linkage rods move towards the side opposite to the running direction of the elevator car and are attracted to the electromagnets in the corresponding direction. According to the air flow self-adaption noise reduction ventilation device for the elevator car, the air guide plate capable of rotating freely and the linkage rod matched with the electromagnet for use are arranged in the air channel of the elevator car wall, when an elevator runs, the air guide plate rotates in one direction under the action of air flow, the linkage rod is driven to attract the electromagnet, and noise is reduced; therefore, the air deflector deflects towards one direction, it is guaranteed that airflow can only pass through the negative pressure area, and the purpose of noise reduction is achieved while the good ventilation effect is achieved.

    本发明涉及一种电梯轿厢气流自适应降噪通风装置,包括设置于电梯轿壁的风道,风道内间隔设置有多个导风板;各导风板的一侧铰接连接有联动杆,风道内设置有两个相对的电磁铁;当电梯轿厢在井道内运行时,各导风板在风道内气流作用下以转动轴为中心线转动,以使联动杆向电梯轿厢运行方向相反的一侧移动并与对应方向上的电磁铁吸合。本发明所设计的电梯轿厢气流自适应降噪通风装置,通过在电梯轿壁风道内设置可以自由转动的导风板和配合电磁铁使用的联动杆,当电梯运行时,导风板在气流作用下转动一个方向,带动联动杆吸附电磁铁,从而使导风板朝一个方向偏转,保证气流只能从负压区通过,实现良好的通风效果的同时达到降噪的目的。
