A self-cleaning platform door for rail transit

PendingCN122078448ARealize dynamic cleaningreduce bring inRailway componentsPower-operated mechanismGear wheelBrush
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.

Agitator trap and agitator trap apparatus

ActiveCN224404988UReduce transfer frequencyreduce breedingAgitatorPhysics
The application provides a stirring collector and a stirring collection device. The stirring collector is arranged in the interior of a tank body of the stirring collection device. The stirring collector comprises a deformable collection net, a cambered collection net and a rotating main shaft. The deformable collection net is connected to the rotating main shaft, so that the deformable collection net can rotate with the rotating main shaft. The deformable collection net extends along the radial direction and the axial direction of the rotating main shaft. The cambered collection net is connected to the radial side of the deformable collection net and extends along the circumferential direction and the axial direction of the rotating main shaft. The deformable collection net comprises a plurality of collection net units, a plurality of rotating parts and a collection unit support. The collection net units are rotationally connected to the collection unit support through one or more rotating parts. The rotating shaft of the rotating part extends along the axial direction of the rotating main shaft or a direction parallel to the axial direction, so that the plurality of collection net units can change the liquid-approaching area of the deformable collection net when rotating around the rotating shaft. The plurality of collection net units are arranged in a matrix on both sides of the rotating main shaft.
