This invention discloses a self-cleaning platform screen door for
rail transit, belonging to the technical field of
rail transit. It includes a door frame, with a motor mounted on the top of the frame. The output shaft of the motor is connected to a connecting shaft via a
pulley mechanism. A gear is fixedly sleeved on the outer side of the connecting shaft, and a rack is fixed to the top of the platform screen door via a rod. It also includes a cleaning mechanism located on the inner side of the door frame. The cleaning mechanism cleans the surface of the platform screen door using a combination of sweeping and vacuuming. This self-cleaning platform screen door for
rail transit, by combining a rolling cleaning
brush with a vacuuming structure, achieves dynamic cleaning of impurities and dust on the platform screen door, avoiding problems of untimely cleaning and increased cleaning difficulty. Furthermore, the platform board connecting the platform screen door and the vehicle can absorb pedestrians' feet and fallen impurities and dust, reducing the amount of impurities and dust brought into the vehicle.
