Drainage structure of municipal road

The utility model discloses a municipal road drainage structure which comprises an outer sleeve shell, a cleaning mechanism and a conveying mechanism. The conveying mechanism comprises a shrinkage pipe connected to the inner wall of the outer sleeve shell through a fixing bolt, a drainage pipe connected to the lower end of the shrinkage pipe, a discharging pipe installed in the center of the shrinkage pipe through a cross-shaped fixing frame, and a transmission rod rotationally installed on the lower portion of the discharging pipe. The spiral conveying blade is fixed on the outer wall of the transmission rod; and the impeller is sleeved at the bottom of the transmission rod. The shrinkage pipe of the conical structure can compress the flowing area of flowing water, so that the water storage speed of the flowing water passing through the drainage pipe is increased, the impeller rotates under the impact of the flowing water, and the impeller rotates to drive the transmission rod to rotate, so that the spiral c
