The invention provides an energy-saving and efficiency-improving transformation method and structure for an oil injection screw type air compressor of a power plant, and the method comprises the following steps: 1, transforming an air inlet mode of a main engine of the air compressor, changing the air inlet mode of the main engine of the air compressor into axial air inlet, shortening an air inlet, forming a bent angle between a rotor and a shell so as to change air inlet from radial air inlet to axial air inlet, the inlet air enters along the axial direction of the rotor; 2, transforming a main engine rotor of the air compressor, and shortening the length of the rotor; and thirdly, the exhaust mode of the main machine of the air compressor is transformed, an air inlet valve is arranged to be a pneumatic flap door, the pneumatic flap door is electrically connected with an electromagnetic valve, the pneumatic flap door is controlled through the electromagnetic valve, and the pneumatic flap door is used for con
