The invention discloses a vertical shaft integrated horizontal self-varied propeller-type wind power generation device. The device comprises a generator; the generator is connected with a main shaft arranged vertically through a speed changer. A plurality of paddle components are horizontally arranged on the excircle of the main shaft along axial direction; each paddle component comprises a shaftsleeve horizontally arranged on the excircle of the main shaft; a rotating shaft of the paddle is arranged in the shaft sleeve; the two ends of the rotating shaft of the paddle are respectively provided with paddles the paddle surfaces of which are vertical with each other; a clamping pin is mounted on the excircle of the rotating shaft of the paddle in a radial direction; a limited groove the width of which is one fourth of circumference of the shaft sleeve is arranged on the inner wall of the shaft sleeve; the clamping pin is arranged in the limited groove along the width direction of the limited groove in a swinging manner. The device of the invention has reasonable design, novel structure, high rotating speed, and great moment of rotation, and can drive generators with high power to work. As the paddle rotates horizontally, and the windage generated by the rotation of the paddle is small, so that high-speed rotation of the paddle can be realized in big wind.
