Abstract

本实用新型涉及一种高楼风力发电系统，尤其是风力发电机叶轮为轴流叶轮(1)和贯流叶轮(2)一体，综合利用高楼(4)天井(3)内的上升气流和高楼(4)高空大气气流两种风能来源，形成风能资源利用互补的叶轮组合共同发电的风力发电系统。由于高楼天井始终存在足够强的上升气流，且台风天气时，轴流叶轮将主动从天井抽气，消耗贯流叶轮产生的动力，起到减速作用。因此，即便在无风、风小或台风情况下，该系统也能正常发电。

Description

轴流贯流叶轮一体型高楼天井风力发电系统
所属技术领域
本实用新型涉及一种高楼风力发电系统，尤其是整合轴流和贯流叶轮，综合利用具有天井结构的高楼天井内因垂直气压差而形成的上升气流及高楼高空大气气流两种风能资源来源共同发电的风力发电系统。
技术背景
迄今为止，风力发电一般都限于空旷地带，无风和风小时就无法发电，从某种程度上来说，风力发电是看天发电。经检索查询，尚未发现整合轴流和贯流叶轮，综合利用高楼天井上升气流和高楼高空大气气流共同发电的风力发电系统的专利或产品、论文。
发明内容
本实用新型提供一种轴流贯流叶轮一体型高楼天井风力发电系统，其综合利用高楼天井内的上升气流及高楼高空大气气流共同发电，在风小甚至无风时也能发电。
本实用新型的技术方案是：一种轴流贯流叶轮一体型高楼天井风力发电系统，由具有天井结构的高楼和风力发电机组成，其特征在于，其风力发电机叶轮为轴流叶轮与贯流叶轮共轴一体形式。其中，贯流叶轮在外，轴流叶轮在内，轴流叶轮扇叶可同时作为贯流叶轮的支架，一体叶轮安置在高楼楼顶天井出口中央，转动轴垂直于地面。
具有天井结构的高楼，由于底层大气气压高，顶层大气气压低，因此在天井内会产生垂直大气气压差(楼高每升高12M，大气压减小1mmHg，大约133Pa)和上升气流，尤其是当高楼天井内布设排热出口(油烟机、燃气热水器等的排气口)和空调室外机，以及天井口形状上小下大时，上升气流更为剧烈，风力可达3-7级，风速可达5-17m/s，这足以驱动风力发电机的轴流叶轮旋转，并使电机输出电能；与此同时，楼顶的大气气流也将驱动贯流叶轮同向旋转。因此，两种叶轮可互补共同为发电电机提供能量。此外，当高楼高空气流风速过高(如台风天气)时，轴流叶轮将主动从天井抽气，消耗贯流叶轮产生的动力，起到减速作用。
本实用新型的有益效果是可确保高楼风力发电系统在任何气候情况(包括无风、风小和台风情况)下都能稳定输出电能。
