如图 1所示, 其为本发明风光塔式发电装置的一优选实施例的结构原 理示意图。 本实施例中, 空气流道隔板 2沿底座 9的上部圆周均匀分布形 成多个空气流道, 且自空气流道入口 1至空气流道出口 5的空气流道截面 逐渐减小, 从而根据流体力学的基本原理来实现对空气流道内流动空气的 加速作用; 本发明中, 空气流道隔板 2 设置数量根据应用场合而定, 使其 能够最大限度地利用从各个方向吹来的风, 此处不予限制。
本实施例中, 空气流道隔板 3在塔式底座 9上分隔出涡旋形空气流道, 以最大限度地减小空气流动阻力。 其中, 空气流道的数量及具体形状可以 视装置的具体应用环境而定, 使其最大限度利用各个方向吹来的风, 以克 服不同季节因风向变化造成的不利影响。
本实施例中, 该顶盖 2采用透明顶盖, 透明顶盖 2通过空气流道隔板 3 固定在底座 9上, 且在顶盖 2下方的空气流道内部设置有吸热材料 4。透明 顶盖 3可以是一体式, 也可以是拼接式, 用来满足不同规模建筑的应用需 求; 吸热材料 4可为长条式絮状体或网栅式, 并可根据需要选择采用单层 排列分布或多层排列分布。 吸热材料 4悬挂在空气流道内部、 透明顶盖 3 的下方, 在白天阳光照射条件下用来吸收透过透明顶盖 3的太阳辐射热能, 提高空气流道内部的温度, 加大空气流道内外的压力差, 增强空气流道内 流场的流速。
进一歩地, 本实施例的风光塔式发电装置中, 透明顶盖采用聚碳酸脂 ( PC ) 、 聚甲基丙烯酸甲酯 (PMMA ) 等透明有机高分子材料或玻璃等透明 无机材料, 采取整体式或者拼装式结构设计, 根据不同建筑规模和制造成 本采取相应的实施方案。 当然并不以此为限, 也可采用其它材料及其他结 构的透明顶盖, 而且, 对于不需要利用太阳光热能的场合, 前述顶盖也可 采用不透明的材质如屋面瓦等, 以节约原材料成本。
本实施例中, 透明顶盖 2与空气流道隔板 3沿底座 9的高度方向采取 多层叠加的结构, 以增大最顶端汇集的风量, 从而增加发电量, 但不以此 为限, 也可采用单层结构。
本实施例中, 空气流道中的吸热材料 4可以为条絮状或网栅状结构, 例如绿色或黑色塑料条, 加工制造和安装使用简便易行, 成本低廉, 吸热 储能性能好; 还可以采用热缓释材料将热能缓慢释放, 起到储能调峰的作 用。
优选地, 本实施例中, 底座 9上表面覆盖有反光材料, 例如铝箔、 镀 银膜等, 使太阳光辐射光能够进一歩投射到吸热材料 4上, 并能加热空气 流道内的空气, 充分利用太阳能。
可选地, 形成空气流道的隔板采用桁架结构, 且桁架外侧设置挡板而 形成风道, 这种结构支撑更加稳固, 强度高。
本实施例中, 空气流道出口 5 上方对应底座顶端的中心位置装设有发 电机支架 8, 如图所示, 叶轮 6装设在空气流道出口 5上方, 通过联轴器与 发电机 7连接, 发电机 7固定在发电机支架 8上。 当然, 该电机支架可以 直接架设于顶盖上方, 本案并不限制。
经空气流道加速后的气流从空气流道出口 5 处快速流出, 推动叶轮 6 旋转, 从而带动发电机 7工作发电, 产生电能向电网或负载供电。
本发明风光塔式发电装置中, 发电机可为直流发电机、 交流发电机、 飞轮蓄电装置或其他通用蓄电池储能装置, 可以视具体工作环境和应用要 求进行选型。 此外, 本发明风光塔式发电装置中, 如果发电机 7结构庞大, 可以将 发电机 7和发电机支架 8安装在底座 9中, 利用刚性或柔性轴穿过透明顶 盖 2和底座 9中心而将叶轮 6与发电机 7相连, 发电机 7由叶轮 6带动发 电, 这种结构方式使整个装置的顶端体积小。 进一歩地, 底座 9还可以延 伸到地下, 这样发电机的震动和噪音更小。
本发明风光塔式发电装置中的底座可以与休憩凉亭、 售货商店、 广告 灯箱、 人造景观等功能建筑相结合, 或者与住宅等建筑屋顶相结合, 也可 以独立地在沙漠、 草原、 滩涂、 水面等风能和太阳能富集的区域建设塔林 风光发电场, 大规模并网发电。
本发明发电储能方法应可通过上述对风光塔式发电装置的描述有所了 解, 其包括: 空气沿空气流道入口进入空气流道并流向空气流道出口, 经 过逐渐缩小的空气流道的增速作用后由汇聚到中心顶部的空气流道出口快 速流出, 从而推动出口处的叶轮旋转, 带动发电机工作发电。
进一歩地, 结合前述对风光塔式发电装置的描述, 可在空气流道中排 列布置有一层或多层吸热材料, 以便白天在阳光照射条件下吸收太阳光辐 射热能, 加热空气流道中的空气, 使其受热膨胀, 增大空气流道内部和外 部环境中的压力差, 加速空气流道顶部空气流道出口处的气流速度, 提高 发电效率, 减小发电装置特别是旋转叶轮所占的体积。
本领域的技术人员可以了解, 前述对本发明发电装置的具体描述均可 应用于此处的发电储能方法, 此处不再一一赘述。
列举本发明的发电方法的一具体实施例如下:
在有风状态下, 空气沿建筑物四周的空气流道入口 1进入空气流道并 流向空气流道出口 5, 依据流体力学基本原理, 通过渐缩型的空气流道的增 速作用后由流道顶部的空气流道出口 5 处快速流出, 推动出口处的叶轮 6 旋转, 叶轮 6带动发电机 7工作发电; 空气流道中排列布置有一层或多层 吸热材料 4, 白天在阳光照射条件下吸收太阳辐射热能, 加热空气流道中的 空气, 使其受热膨胀, 增大了流道内部和外部环境中的压力差, 能够加速 空气流道顶部空气流道出口 5 处的气流速度, 尤其在傍晚外部环境温度降 低时, 吸热材料 4对流道内部气体的加热效果更加明显, 能有效提高发电 效率。
虽然本发明已以具体实施例揭示, 但其并非用以限定本发明, 任何本 领域的技术人员, 在不脱离本发明的构思和范围的前提下所作出的等同组 件的置换, 或依本发明专利保护范围所作的等同变化与修饰, 皆应仍属本 专利涵盖的范畴。
