Embodiment Construction

[0028] As shown in the drawings, the present invention includes an impeller 4 composed of a vertical shaft 7 and sail blades, and a wind-control casing 3 mounted on the outside of the impeller 4. The sail blades are composed of a frame 11 and a tarpaulin 12. The frame 11 is rectangular , It is made of pipe welding with a rectangular cross section. There are several reinforcing ribs on the frame 11 to improve its strength. A number of movable hangers 13 are fitted on the frame 11, and the movable hangers 13 can move on the frame 11. , There is a cylinder on one side of the movable hanger 13, and there is a groove around its circumference on the cylinder. The tarpaulin 12 is made of canvas, nylon cloth and other sturdy cloth, and its shape is the same as that of the frame 11. There are several metal rings on the periphery of the tarpaulin 12, and each metal ring is matched with a movable hanger 13, that is, the metal ring on the tarpaulin 12 is sleeved in the groove of the cylinde...

Abstract

The invention relates to a large-wind sail vertical rotation type wind power generation tower, and solves the problems of the existing wind driven generator, such as difficult effective matching between wind wheels and a generator and low wind wheel power. The large-wind sail vertical rotation type wind power generation tower comprises impellers composed of an upright shaft and a wind sail blade,and wind control shells arranged outside the impellers. The large-wind sail vertical rotation type wind power generation tower is characterized in that multiple impellers and wind control shells are arranged and are mounted in multiple frames respectively and installed together vertically; the upright shafts of all impellers are connected with each other; and the upright shaft of the downmost impeller is connected with the main shaft of a variable-power generator, thus forming the large-wind sail vertical rotation type wind power generation tower. The invention has the advantages that as the variable-power generator is connected with the upright shafts of the impellers, the problem of difficult effective matching between the generator and the impellers is solved, and the impellers can be matched with the generator under any wind force, thereby reducing dependence on wind and improving the wind wheel power and the generating efficiency.

Description

Technical field [0001] The invention belongs to a wind power generation device, in particular to a large sail vertical rotation wind power generation tower. Background technique [0002] At present, the world's energy resources are becoming increasingly tense, and wind energy as a clean energy source has attracted more and more attention. The existing wind power generator is mainly composed of a wind wheel, a tower barrel and a generator. The wind wheel is composed of three or more blades, the blades are fixed on the axle disc, and the axle disc is installed on the tower bucket. Due to the small wind-receiving area of ​​the blades of this kind of wind wheel, each blade is very long and large in size, so the tower barrel is very high. The tower barrel of the high-power wind turbine is even more than 100 meters high, with a diameter of several meters. , And the tower barrel is rotating and requires a giant bearing with a diameter of several meters to support it. The problems of ...
