The invention discloses a ventilation device for an elevator. The ventilation device comprises an elevator body, the same mounting strip is welded to the upper portions of the inner walls of the two sides of the elevator body, a servo double-output-shaft motor is mounted on the outer wall of the top of the mounting strip through bolts, ventilation fan blades are connected to a first output shaft of the servo double-output-shaft motor in a sleeving mode and located below the mounting strip, a ventilation box with an opening in the bottom is welded to the outer wall of the top of the elevator body, a convection hole is formed in the top of the ventilation box, and a second output shaft of the servo double-output-shaft motor is connected with a lead screw through a coupler. Ventilation and filter screen cleaning can be conducted at the same time, so that the cost is saved, and electric power resources are saved. The lead screw rotates to drive a sliding rod welded to a threaded sleeve todo reciprocating motion in a sliding groove, and finally, under the action of a connecting rod, a brush strip can clear impurities accumulated on the surface of a filter screen. Therefore, the filtering effect of the filtering screen can be guaranteed, and normal operation of the ventilation device is facilitated.
本发明公开了一种电梯用通风装置,包括电梯本体,所述电梯本体的两侧内壁上部焊接有同一个安装条,且安装条的顶部外壁通过螺栓安装有伺服双出轴电机,所述伺服双出轴电机的第一输出轴上套接有通风扇叶,且通风扇叶位于安装条的下方,所述电梯本体的顶部外壁焊接有底部为开口的通风箱,且通风箱的顶部开设有对流孔,所述伺服双出轴电机的第二输出轴通过联轴器连接有丝杆。本发明能够让通风和清理过滤网同时进行,这样节约了成本,节约了电力资源,而且丝杆转动带动螺纹套上焊接的滑杆在滑槽内做往复运动,这样最终在连杆的作用下,毛刷条能够对过滤网表面堆积的杂质进行清理,从而能够保证过滤网的过滤效果,有利于通风装置的正常进行。
