Wind assembling wind power generator

The utility model relates to a windmill generator, in particular to a windmill generator that can concentrate the wind. In the technical proposal, the windmill generator comprises an active wind cover, a rudder, a flexible catheter, a wind-collecting cylinder, a generator and a blade. The windmill generator is characterized by comprising a plurality of mobile wind-collecting wind covers; the rudder is arranged in each wind-collecting wind cover; and the wind covers are connected with the wind-collecting cylinder through the flexible catheter. And the windmill generator solves the problem of the instable rotating speed of the generator as a result of insufficient wind force and instable wind direction.
