The invention discloses an intelligent railway signal machine. The intelligent railway signal machine comprises a rotating mechanism, three adjusting mechanisms and a cleaning mechanism, wherein a first motor of the rotating mechanism drives the adjusting mechanisms to rotate, signal lamps in the adjusting mechanisms are driven to rotate, the rotating mechanism adjusts the angles of the signal lamps connected with first fixing rods, and the cleaning mechanism can periodically clean protective panels. According to the intelligent railway signal machine, the rotating mechanism is used for driving the signal lamps to rotate, and meanwhile, the angles of the signal lamps are adjusted through the adjusting mechanisms, so that the signal lamps emit dynamic light with variable angles and rotation; in the haze, rain and other poor visibility extreme weather, the dynamic light is easier to find compared with traditional static signal light, and thus the signal transmission effect in the extremeweather is improved; and the cleaning mechanism is used for cleaning the protective panels of the signal lamps, additional cleaning equipment or manual cleaning does not need, and thus the maintenance management cost is reduced.
