Abstract
本实用新型公开了一种风力发电机半球形风叶的改进结构,所述风力发电机为垂直轴风力发电机,其主轴上固定有多个呈水平枝状伸展的中空的半球形风叶,半球形风叶的球面底部截有圆形、方形或其它几何形状的开口;与所截球面部分形状相同、稍大于或稍小于所截球面部分的活动翻板,通过开口上方的活页固定在内球面并覆盖在开口上;外球面上靠近开口周边固定有多个支架,每个支架上固定有垂直伸向开口的缓冲棒,其靠近开口内沿,端部略向开口内伸出。上述结构由于在半球形风叶的球面底部采用了活动翻板结构,消除了位置相对的两个半球形风叶之间的风力抵销影响,从而保证发电机顺利运转发电,另外,缓冲棒的设置,可以避免活动翻板盖下时与风叶底部的开口边缘碰撞产生噪音。
The utility model discloses an improved structure of a hemispherical wind blade of a wind power generator. The wind power generator is a vertical axis wind power generator, and a plurality of hollow hemispherical wind blades extending in a horizontal branch shape are fixed on the main shaft. The bottom of the spherical surface of the hemispherical fan blade is cut with a circular, square or other geometric opening; the movable flap with the same shape as the cut spherical part, slightly larger or slightly smaller than the cut spherical part, is fixed by the loose leaf above the opening The spherical surface covers the opening; multiple brackets are fixed on the outer spherical surface close to the periphery of the opening, each bracket is fixed with a buffer rod extending vertically toward the opening, which is close to the inner edge of the opening, and the end slightly protrudes into the opening. The above-mentioned structure adopts a movable flap structure at the bottom of the spherical surface of the hemispherical fan blade, which eliminates the wind force offset effect between the two hemispherical fan blades in opposite positions, thereby ensuring the smooth operation of the generator to generate electricity. In addition, the buffer rod It can avoid the noise caused by collision with the edge of the opening at the bottom of the fan blade when the movable flap cover is lowered.
