Detailed Description

The present invention will be further described with reference to fig. 1 to 4.

A novel vertical axis wind power generation device comprises a central shaft 1, a rotary drum 2, five blades 3, five support rods 4, five connecting rods 5 and a sleeve 13. The bottom end of the central shaft 1 is provided with a boss 14, and one end of the central shaft 1 is connected with a power generation rotor. The blades 3 are arranged in the circumferential direction of the drum 2. The support rods 4, the blades 3 and the connecting rods 5 correspond to one another. One end of the support rod 4 is integrally formed with the rotary drum 2, and the other end of the support rod 4 is hinged with the blade 3. Sliding connection has slider 9 on the bracing piece 4, one side of bracing piece 4 is provided with corrugated recess 11, slider 9 is connected with set screw 10, set screw 10 can open and shut and connect in recess 11 to make bracing piece 4 and slider 9 relatively fixed. One end of the connecting rod 5 is hinged with the blade 3, and the other end of the connecting rod 5 is hinged with the sliding block 9. The relative position between the slide block 9 and the support rod 4 is adjusted, so that the extension and contraction of the connecting rod 5 can be realized, and the relative angle of the blades can be changed.

The rotating cylinder 2 is sleeved with the central shaft 1, and the rotating cylinder 2 can slide along the axial direction of the central shaft 1 and can be relatively fixed with the central shaft 1. Specifically, the outer surface of the central shaft 1 and the inner surface of the rotary drum 2 are both provided with transmission threads, the rotary drum 2 is connected with the central shaft 1 in a matching manner, and the rotary drum 2 can realize the axial sliding of the rotary drum 2 along the central shaft 1.
