The utility model relates to an inclined lifting tower or a yaw and mated overlapping blade at the bottom of a tower cylinder. The utility model has three characteristics: the first is a yaw structure that a ring-shaped girder, an upper and a lower guide rail and a multi-wheel trolley are arranged between a base upright column and the tower or the tower cylinder; the second is a channel fan unit consisting of a pair of tower guide rails and a pair of towers or tower cylinders which can be lifted according to needs; the third is the mated arrangement of the wind blade that two pairs of wind blades are +-shaped in full-load operation and are horizontally overlapped as a-shaped structure when stopping and landing on the ground. The utility model has the advantages of better use of wind energy, being more conducive to ground maintenance and good anti-typhoon performance of tower-type structure.
