Embodiment Construction

[0026] Such as figure 1 , Figure 5 with Image 6 As shown, the vertical axis wind power generation device with the blades automatically adjusting the windward side of the present invention includes a plurality of blades 1, a rotating frame 4, a blade support disc 5, a vertical generator input shaft 11, a blade support disc 5 and an input shaft 11 between the transmission mechanism.

[0027] Such as Figure 5 As shown, the upper and lower fixed brackets 2a, 2b are provided on the back of the fan blade 1, and the outer side of the rotating frame 4 is pivotally or hingedly connected to the upper and lower fixed brackets 2a, 2b on the back of the fan blade 1 or can be rotated around an axis. Connected, the fan blade 1 can be rotated on the line connecting the hinge joints of the upper and lower fixed brackets 2a, 2b and the swivel frame 4 as the axis, and the inner side of the swivel frame 4 is fixed on the support plate 5 . The upper end of the back of the fan blade 1 is equ...

Abstract

The invention relates to a vertical axis wind power generating device and a fan blade angle automatic regulation mechanism thereof; the vertical axis wind power generating device comprises a plurality of fan blades, a fan blade supporting tray, an input axis, a transmission mechanism between the fan blade supporting tray and the input axis and is characterized in that the vertical axis wind power generating device also comprises the fan blade angle automatic regulation mechanism which comprises a plurality of rotating frames, a crank axis, an eccentric axis, an eccentric connecting tray, a wind rudder, and a plurality of fan blade draw bars, wherein the outer side of each rotating frame is articulated with the back of the corresponding fan blade and the inner side is fixed on the fan blade supporting tray; the crank axis is relatively and rotatably connected with the input axis and coaxial with the input axis; the eccentric axis which is relative to the axis center of the crank axis is eccentrically and fixedly arranged on the crank axis; the eccentric connecting tray is rotatably arranged on the eccentric axis; the wind rudder is fixedly arranged on the eccentric axis; and the outer end of each fan blade draw bar is rotatably connected with the corresponding fan blade and the inner end is rotatably connected with the eccentric connecting tray.

Description

technical field [0001] The invention relates to a vertical axis wind power generating device and an automatic adjustment mechanism for the angle of the fan blades. Background technique [0002] The Chinese patent application with the publication number CN1858438 discloses a vertical axis wind power generation device, which is provided with a shaft at the center of rotation of the fan blades, and the fan blades rotate back and forth around the shaft on the bracket to form a wind wheel. When the fan blades rotate back and forth on the bracket The angle range is determined by the automatic control system to control the blade rotation angle, and the blade obtains the corresponding optimal blade rotation angle at different positions. [0003] But no matter what kind of method of changing the blade angle is adopted, there will be the following defects. [0004] The disadvantage is that the corner blades are on the downwind side, and the corner blades cannot be 90 degrees with the...
