Mobile power station and collecting disc pipe device thereof

A collecting disc pipe device comprises a roller for a pipeline to be wound. A rotating shaft that supports the rotation of the roller is fixedly connected inside the roller along a center shaft of the roller, the two ends of the rotating shaft are rotatably connected to supports positioned at the two ends of a roller base, and the roller base is arranged on a flat car of a mobile power station train. Due to the fact that the roller can be used for the winding of the pipeline, the rotating shaft rotates on the roller base to drive the roller to rotate, the pipeline on the roller is gradually wound around the roller along with the rotation of the roller, the roller base is arranged on the flat car and can move along with the mobile power station train, and the purposes of conveniently and quickly pulling and retracting an air supply pipe are achieved. The invention further provides a mobile power station comprising the collecting disc pipe device.
