The invention discloses a dust removing type road protection board. The dust removing type road protection board comprises a board body; a rotating rod is inserted in the external wall of one side ofthe board body; a rotating disc is fixed at the end part of the rotating rod; multiple fan blades are uniformly fixed on the external wall of the rotating disc; a cam is fixed at one end, positioned in the board body, of the rotating rod; a magnet arranged in a U shape is arranged in the board body; a coil rod is arranged in the magnet; a frame body is arranged outside the magnet in a sleeving manner; the external wall of the cam is in contact with the external wall of the frame body; the two ends of the coil rod are fixed on the internal wall of the frame body; an electrostatic transmission rod is also fixed in the board body; and the coil rod is connected with the electrostatic transmission rod through a lead. According to the dust removing type road protection board, the cam is driven to rotate through airflow formed during the running of a vehicle so as to realize the movement of the coil rod so that a magnetic induction line is cut; and therefore, current is generated to enable the electrostatic transmission rod to generate static electricity to adsorb the dust; and meanwhile, through water drainage, secondary flying of the dust is avoided.
