Embodiment Construction

[0011] As shown in the figure, the upper end of the central shaft 1 is riveted with a flat beam 2 , and the two ends of the flat beam 2 are welded or riveted with a blade support 3 . The blade 4 and the blade shaft 5 are welded or riveted into one body. The blade shaft part is installed on the outer end of the blade support 3 through a bearing. After the installed blade shaft part is installed, when the blade support 3 enters the downwind running position, the blade 4 sticks to the blade The support 3 cannot swing; when the blade support 3 enters the upwind operation position, the blade shaft part can flexibly swing back and forth. In order to reduce the noise generated by the collision of the blade 4 with the blade bracket 3 when the blade 4 swings, soft materials are installed on the rod of the blade bracket 3 and where the blade 4 and the bracket contact. The wind wheel assembly is installed on the top of the tower 9 through the central shaft 1 and a pair of tapered roller ...

Abstract

A vertical axis wind turbine wind wheel comprises a central shaft, a beam, a blade frame, blades, a blade shaft, a transmission shaft, a braking device and a tower post. When rotating downwind, the blades stick to the blade frame and can not swing, and the wind drives the blades and the frame to generate a moment to the central shaft by the beam and the central shaft rotates therewith. When rotating upwind, the blades swing to be parallel to the direction of the wind through a bearing, therefore the blades do not have thrust and resistance. The wind wheel has a large wind susceptible area, small upwind resistances, high wind energy utilization rate, simple structures, firm and durable properties, and more suitable for matching with the high power generators.

Description

technical field [0001] The invention belongs to the scope of wind power machine equipment, and in particular relates to a wind wheel of a vertical axis wind power machine. technical background [0002] The use of wind energy, a renewable energy source, for power generation has been highly valued and practically applied. There are two main types of wind turbine rotors currently in use, one is a horizontal axis rotor and the other is a vertical axis rotor. In a nutshell, the structure of the vertical axis is simpler than that of the horizontal axis, and the production cost, operation and maintenance costs are lower. However, as far as the application of wind turbines in the field of power generation is concerned, the application of horizontal-axis wind rotors is much more common than that of vertical-axis wind rotors. Matching wind wheel. The vertical-axis wind rotors that have been used, such as S-type wind rotors and Darrieus wind rotors, are difficult to design and proce...
