Horizontal double-rotor wind driven generator

The utility model discloses a horizontal double-rotor wind driven generator which comprises an inner rotor; an outer rotor is coaxially sheathed outside the inner rotor; a bearing is arranged between an inner rotor shaft and an end surface shell of the outer rotor; one end of the inner rotor shaft stretches out of the end surface shell of the outer rotor, and is connected with a first fan blade; a shaft on the end surface shell of the outer rotor is connected with a second fan blade; the rotation directions of the vanes of the first fan blade and the second fan blade are opposite; the shaft on the end surface shell has a hollow structure; the end surface shell of the outer rotor is arranged on a bracket; a bearing is arranged between the shaft on the end surface shell of the outer rotor and the bracket; and the bracket is an insulation body. The horizontal double-rotor wind driven generator with the structure uses two wind wheels with opposite rotation directions to respectively drive the inner rotor and the outer rotor to rotate along opposite directions; while the inner rotor and the outer rotor do not have any transmission relationship; and in the way, the running resistance of the generator is low, and the wind conversion efficiency is high. The horizontal double-rotor wind driven generator has simple structure, is vertically arranged, and can be used for places like families, small wind fields, etc.
