The invention discloses a tower-type wind driven generator which comprises a connecting rod and an impeller, wherein the impeller is of an integral structure, is not provided with a hub, and is composed of three blades; front end of the impeller is hinged to top end of the connecting rod; every two blades of three blades of the impeller are connected through a hinge; a spring and a sliding sleeve are arranged on the connecting rod; tail end of the spring is fixedly connected with the connecting rod, and the other end of the spring is connected with the sliding sleeve; a support rod is hinged to the impeller; and the other end of the support rod is hinged to the sliding sleeve. The tower-type wind driven generator has self-adaptability to the wind speed and other advantages; an installing angle can be increased or decreased according to the wind speed, so that the best reduction ratio can be realized, the working mode of starting at a low wind speed and operating at a high wind speed is realized, and the wind energy is fully and efficiently utilized.
