Drainage device for heat distribution pipeline construction

The utility model relates to the field of drainage devices, in particular to a drainage device for heat distribution pipeline construction. The cleaning device comprises a pipeline body, a rotating shaft arranged in the axial direction of the pipeline body, a cleaning piece arranged on the rotating shaft, a driving shaft rotationally connected to the pipeline body in the radial direction of the pipeline body, a driving motor arranged outside the pipeline body and connected to the driving shaft, and a transmission shell rotationally connected with the rotating shaft. The first bevel gear is coaxially and fixedly connected to the driving shaft, the second bevel gear is coaxially and fixedly connected to the rotating shaft and meshed with the first bevel gear, the end of the driving shaft extends into the transmission shell, and the first bevel gear and the second bevel gear are both located in the transmission shell. The heat distribution pipeline has the effect of improving accumulation of impurities in the he
