摘要： A wind-driven power generator comprises a substantially horizontal roof including upper and lower roof members each having a peripheral edge and a contoured pressure reducing surface. The roof members are disposed in a spaced-apart relationship with the pressure reducing surfaces facing each other and defining an air space therebetween. The distance between the pressure reducing surfaces varies from a maximum spacing at the peripheral edges of the roof members to a minimum spacing at an intermediate location of the roof members. The power generator further includes a vertical suction pipe having an upper end connected to the lower roof member in flow communication with the air space at the intermediate location of the lower roof member. The lower end of the suction pipe extends downwardly from the lower roof member. An impeller is disposed in the suction pipe at the lower end thereof and rotates when air flows horizontally through the air space. In accordance with Bernoulli effect, the increase in speed of the horizontal air flow at the intermediate location creates a pressure reduction in the air space at the upper end of the suction pipe and draws air up through the suction pipe to rotate the impeller. The impeller preferably is connected to an electrical generator that generates electricity when the impeller rotates.
摘要翻译：风力发电机包括基本上水平的屋顶，其包括具有周边边缘和轮廓减压表面的上部和下部屋顶构件。屋顶构件以与彼此面对的减压表面间隔开的关系设置并且在它们之间限定空气间隔。减压表面之间的距离从屋顶构件的周边边缘处的最大间距变化到屋顶构件的中间位置处的最小间距。发电机还包括垂直吸入管，其具有连接到下部屋顶构件的上端，与下部屋顶构件的中间位置处的空气空间流动连通。吸入管的下端从下部屋顶部件向下延伸。叶轮在其下端设置在吸入管中，并且当空气水平地流过空气空间时旋转。根据伯努利效应，在中间位置处的水平空气流速的增加在吸入管的上端处的空气空间中产生压力降低，并且通过吸入管抽吸空气以使叶轮旋转。叶轮优选地连接到当叶轮旋转时发电的发电机。
