Detailed Description

As shown in fig. 1, 2 and 3, the offshore liftable wind power generation device comprises a blade 1, a nacelle 2, a tower 3, a rack 4, a floating type base platform 5 and a gear 6. The upper end of the tower barrel 3 is provided with a cabin 2, the generator set is positioned in the cabin 2, and a connecting shaft of the generator set extends out of the cabin to be connected with the blades 1; when the blades 1 are blown by wind, the blades 1 drive a generator set in the engine room 2 to generate electricity, and current generated by the generator set is converted into direct current through the controller and is stored in a storage battery in the tower 3. The engine room 2 is provided with two sets of generator sets, and the two sets of generator sets extend out of the engine room along the axial direction and are respectively and rotatably connected with the blades 1. At least two racks 4 are fixed on the outer surface of the cylinder body of the tower drum 3; for example, as shown in fig. 1, the number of the racks 4 is three; the rack 4 is vertically arranged from the middle upper part of the tower 3 to the bottom of the tower 3, and the rack is evenly distributed on the outer surface of the tower 3. The floating type basic platform 5 consists of at least four supporting cylinders and a platform; for example, as shown in FIG. 1, four support cylinders are used; each supporting cylinder is a hollow cylindrical cylinder structure which is sealed up and down; one of the supporting cylinders with thicker pipe diameter and higher height is positioned in the middle, and the other supporting cylinders are uniformly distributed around the supporting cylinder; the supporting cylinders distributed on the periphery are connected in pairs through connecting rods and are fixedly connected to the supporting cylinder in the middle. The upper end surfaces of the supporting cylinders distributed on the periphery are communicated with each other to form a platform of an integrated structure.
