The motor case 5 is installed below the generator case 4, and the generator case 4 and the motor case 5 share one housing or can be separately provided with different housings. The motor in the motor case 5 is supplied with power by the generator in the generator case 4. The output shaft of the motor is in transmission connection with the second transmission assembly 6, and the cylindrical rolling brush 8 is driven by the second transmission assembly 6 to clean the track.
As shown in fig. 1 and 3, the cylindrical roller 22 is uniformly provided with a plurality of sliding grooves along the circumferential direction, each sliding groove is internally provided with a spring (not shown in the figure), one end of each spring is fixedly connected with the groove bottom of the corresponding sliding groove, the other end of each spring is fixedly connected with a corresponding fan blade 21, and each fan blade 21 is inserted into the corresponding sliding groove and partially extends out of the sliding groove under the action of the spring. The cylindrical roller 22 is rotatably connected with the fan blade shaft 23 through a one-way rotary bearing 9.
The generator box 4 is installed on one side of the electric box 1 and is in transmission connection with the combined fan blades 2 through the first transmission component 3.
When the subway runs through the side of the track, airflow is generated, under the action of the airflow, the fan blades 21 rotate, in the rotating process, the fan blades 21 slide out of the sliding grooves due to the action of centrifugal force, and the cylindrical rollers 22 are driven to rotate, so that wind energy is converted into mechanical energy.
