与现有技术相比， 本发明的百叶式流体动力装置的有益效果在于:
1、 本发明的百叶式流体动力装置利用处于顺流区内的轮叶上的窗 叶可以自动掩盖以关闭轮叶上的窗口及处于逆流区内的轮叶上的窗叶 可以自动翻开以打开轮叶上的窗口， 使半数轮叶迎着流体流动方向回 转时其上的窗口处于打开状态， 大大降低对流体流动所造成的阻力， 同时又使半数轮叶上的窗口处于关闭状态， 受流体动力带动而不断转 动， 进而带动轮轴转动， 转动的轮轴可以不断的向外输出动力。
2、 本发明的百叶式流体动力装置置于大气中有风流动的地方时， 因可以扩大轮叶受风面积， 用作风力发电的效果更显著。
3、 本发明的百叶式流体动力装置又可整个藏于水中， 因此对自然 环境及生态环境造成的损害甚轻微， 而且亦对船只通航航道不会有太 大影响， 同时该百叶式流体动力装置置于河流及洋流中时， 受环境局 限较小， 可以建造较大体积以求得到较大输出功率。
4、 本发明的百叶式流体动力装置由于利用的是风力或水流动力能 源， 二者同样都是物理能源， 具有一直存在、 力量庞大、 用之不尽以 及不会污染环境的优点。

首先需要说明的是： 下文中提到的转向面指的是当轮轴呈水平状 态放置于大气中或水中时， 平行于流体流动方向且经过轮轴轴线的平 面。 所述转向面把空间划分了两个区域， 所述轮叶顺着流体流动方向 转动的区域是顺流区， 所述轮叶逆着流体流动方向转动的区域是逆流 区。 中垂面是指与流体流动方向垂直且经过轮轴轴线的平面。 本发明提出的百叶式流体动力装置放置于有气流存在的大气中或 有水流存在的水域中， 处于所述顺流区内的所述轮叶上的窗叶因流体 推动作用而自然地掩盖着所对应的所述窗口， 同时处于所述逆流区内 的所述轮叶上的窗叶亦因流体推动作用而自然地翻开所对应的所述窗 口， 使所述轮叶受流体流动作用带动轮轴转动以向外不断的输出动力。
具体地， 如图 1和图 2所示， 本发明公开的一种百叶式流体动力 装置包括轮轴 2和多个轮叶 1，轮叶 1沿轮轴 2的轴向固定在轮轴 2上， 且多个轮叶 1在轮轴 2上均匀分布并呈辐射状设置， 在水流或气流的 流体动力作用下轮叶 1的旋动将带动轮轴 2单向转动。
轮叶 1由图 2所示的一个轮叶骨架 7构成， 轮叶骨架 7内形成多 个中空疏通的窗口 4。本实施例中， 窗口 4通过横纵交叉设置的杆状体 分隔而成。 而每个窗口 4上都设置有在顺流区 11用于盖住窗口 4而在 逆流区 12自动打开窗口 4的窗叶 3， 并且所有窗叶 3都置于轮叶 1的 同一侧。 如图 2所示， 本实施例中公开的轮叶骨架 7为长方形， 而每 个窗口 4也为长方形， 长方形窗口在制造上最为经济并且制造效率最 高。 并且使长方形窗口较长的一边与轮轴轴线 6平行， 这样， 铰接在 窗口外缘 5的窗叶 3翻开时较为方便。实际上， 本发明中的轮叶骨架 7 和窗口 4并不仅限于此种形式， 比如轮叶骨架 Ί的结构为曲线形或扇 形， 窗口 4 的形状也可以为弧形或其他形状， 只要在流体的推动下能 实现轮叶 1带动轮轴 2单向连续转动即可。此时， 窗叶 3要根据窗口 4 的形状变化而变化， 但窗叶 3翻开及掩盖动作的方向不变。
另外， 图 2中本实施例中的每个轮叶 1沿轮轴 2的径向开设四个 窗口 4只是一种示意， 实际上径向窗叶 3的数目可以按实际要求而定 并没有限制。 而且每个轮叶 1沿轮轴轴线 6方向设置的窗口 4的数量 也不仅限于八个， 可以根据实际需要而定。 为了清楚起见， 图 2仅示 出了窗口 4，而没有显示出窗叶 3，图 2中以深色标示其中一窗口空间。
为了实现窗叶 3转动连接在窗口 4上， 以使窗叶 3在流体的推动 下在顺流区 11掩盖住窗口 4， 而在逆流区 12打开窗口 4， 窗叶 3可采 取多种方式实现转动连接。 如图 3至图 5所示， 窗口 4远离轮轴 2的 边缘（该实施例中即为与轮轴 2平行的边缘， 以下简称窗口外缘 5 )上 设置有榫眼 9，窗叶 3上设置凸出的用于插入榫眼 9内以使窗叶 3转动 连接在窗口 4上的榫头 8。如图 6至图 8所示， 窗叶 3也可以通过铰链 10铰接在窗口外缘 5上。还可以通过如图 9至图 11所示的方式实现窗 叶的转动连接， 窗口外缘 5上设置轴杆 16， 窗叶 3上设有用于使轴杆 16穿入的窗叶孔 17， 从而使窗叶 3转动连接在窗口外缘 5。 如果窗口 外缘 5本身是圆杆状的， 则可以取消增设的轴杆， 可直接使窗口外缘 5 穿过窗叶孔 17， 使窗叶 3转动连接在窗口外缘 5上。
继续结合图 3至图 8， 为了使窗叶 3掩盖住窗口 4， 以使在顺流区 11内轮叶受到流体的推动力增大， 本实施例中的窗叶 3的面积稍大于 所对应的窗口 4的面积， 致使窗叶 3足以完全封盖所对应的窗口 4， 而 为了保证彼此之间的动作不相互影响， 相邻的窗叶 3之间应不重叠。
当然， 如果窗叶 3的面积不大于窗口 4的面积也是可以的， 如图 9 至图 11所示， 窗叶 3的面积稍小于或等于所对应的窗口 4的面积， 窗 口 4的边缘上设置挡条 15用于使窗叶 3永远位于窗口 4的同一侧而不 会转动至窗口 4的另一侧。挡条 15的作用主要是当窗叶 3位于顺流区 11受流体作用力时使其压着轮叶骨架 7， 因为挡条 15的存在， 窗叶 3 所受的流体的作用力便通过挡条 15传递到轮叶骨架 7， 从而带动轮轴 2转动。 挡条 15的设置形式可以有多种， 而并不仅限于图 9中示出的 短小条形的情况，例如，挡条 15可以设置为贯穿整个窗口 4的长条形， 条形既可以是水平的也可以是竖直的， 当然还可以是倾斜的， 而且挡 条 15也可以设置为多条。 另外， 挡条 15也可以是在窗口 4内形成的 多格状结构。
如图 4、 图 5、 图 7、 图 8、 图 10和图 11所示， 本实施例中的窗 叶 3为非平面的， 而是带有一定的弧度， 即窗叶 3的一侧面向另一侧 面内凹， 而另一侧面则相应的外凸， 内凹的一面靠贴轮叶骨架 7， 外凸 的一面背向轮叶骨架 7。 这样设置的目的是使在顺流区 11的窗叶 3更 好的贴靠在窗口 4上， 并且也能相应增大流体作用到窗叶 3上的推动 力。 当然， 如果窗叶 3设置为平而没弧度的也是可以的， 窗叶 3也会 在流体的推动作用下， 在逆流区 12内打开窗口 4， 而在顺流区 11内则 关闭着窗口 4。
另外， 继续参照图 2， 本实施例中的窗口 4是由相互垂直的横向杆 状体和纵向杆状体交叉形成， 相邻两个所述横向杆状体的间距相等， 而相邻两个所述纵向杆状体的间距相等， 从而使形成的窗口 4 的大小 形状完全相同， 实际上， 各窗口 4之间的大小形状可以不相同。 而且 本实施例中示出的是每个窗口 4上分别转动连接了一个窗叶 3，实际上 也可以两个甚至更多个窗口 4共用一个窗叶 3。或者一个窗口 4设置两 个或更多个窗叶 3也是可行的。 但应保证窗叶 3永远位于窗口 4的同 一面， 而在转动的过程中不转到窗口 4的另一面。 当多个窗口 4共用 一个窗叶 3时， 相邻两个窗口 4之间的框架则起到了挡条 15的作用。
本发明的百叶式流体动力装置使用时可以依轮轴轴向水平设置 (如图 1至图 2所示），或可以依轮轴轴向垂直竖立设置（未给出图示）。 但无论是水平设置还是垂直设置， 百叶式流体动力装置的结构是相同 的， 而且工作的原理也是相同的， 窗叶 3铰接于窗口外缘 5。 当本发明 的百叶式流体动力装置放置于流体中时， 如有气流存在的大气中或有 水流存在的水域中， 流体流动方向与轮轴轴线相交构成了转向面 13， 所述转向面 13把空间划分了顺流区 11及逆流区 12，处于顺流区 11的 轮叶 1上的窗叶 3会因为流体推动作用而掩盖着窗口 4， 处于逆流区 12的轮叶 1上的窗叶 3会因为流体推动作用而翻开打开着窗口 4， 使 在逆流区 12中的轮叶 1逆流回转时减小阻力， 同时使在顺流区 11的 轮叶 1受流体流动作用带动轮轴转动以向外不断的输出动力。
另外， 当轮轴 2竖直放置时， 本发明的百叶式流体动力装置除了 采用和轮轴 2水平放置时的结构相同外， 还可以采用如图 12和图 13 所示的结构。 如图 1和图 12所示， 两者的区别仅在于窗叶 3铰接在窗 口 4上的位置不同， 而其他结构完全相同。 继续结合图 12， 窗叶 3转 动连接在窗口 4垂直于轮轴轴向的一侧边缘上， gp， 如图 13所示， 当 轮轴 2竖直放置时， 窗叶 3铰接在窗口 4的窗口上缘 18上。 下面结合附图以轮轴水平设置为例对本发明的百叶式流体动力装 置的工作原理和工作过程简要介绍如下：
使用时， 将本发明的百叶式流体动力装置置于流体中， 即如图 1 的方式放置。
下面以其中四片轮叶 1为例进行说明， 如图 14和图 15所示， 现 将该四片轮叶分别定义为轮叶 la、 轮叶 lb、 轮叶 lc和轮叶 ld， 并且 图 14和图 15中的箭头方向标示流体的流动方向。
如图 14所示， 在顺流区 11中的轮叶 la转动至接近转向面 13时， 稍微外凸的窗叶 3的凸面仍受流体推动作用而关闭着窗口 4 (如果窗叶 3不外凸也是一样的）， 轮叶 la继续转动而越过转向面 13进入逆流区 12， 跟着如图 15所示， 轮叶 lb的窗叶 3的凹面迎着流动的流体， 受 流体推动作用而自然翻开打开窗口 4。
基本上， 轮叶 la在进入顺流区 11而还没越过中垂面 14时， 所受 流体推动的作用力最显著， 轮叶 la越过中垂面 14后， 受流体推动的 作用力便减弱了， 此时流体仍会依原流动方向流动， 除了重力外， 再 没有其它力作用在窗叶 3上， 若置于水中， 窗叶 3会采用比重或有效 比重与水相当的物料制造， 使轮叶 la所受重力与水的浮力抵销了， 所 以轮叶 la在越过中垂面 14后， 窗叶 3仍然会靠贴着窗口 4， 毕竟在实 际情况下， 流体流动方向或许稍有变化，但因窗叶 3铰接在窗口外缘 5 而可以自由活动， 尽管在轮叶 la还没越过转向面 13进入逆流区 12， 窗叶 3可能会因受实际情况而变化的流体作用力稍为翻开， 但也不会 构成对轮叶 la转动的阻力。 若置于大气中， 窗叶 3会用较轻的物料制 造， 窗叶 3或许会在未越过转向面 13进入逆流区 12前稍为翻开也不 会构成对轮叶 la转动的阻力。
再如图 14所示， 在逆流区 12中的轮叶 lc转动至接近转向面 13 时，稍微外凸的窗叶 3的凸面受流体推动作用而半关闭着窗口 4 (如果 窗叶 3不外凸也是一样的）， 轮叶 lc继续转动而越过转向面 13进入顺 流区 11，跟着如图 15所示，轮叶 Id的窗叶 3的凸面迎着流动的流体， 受流体推动作用而关闭着窗口 4。 因为流体动力作用， 流体不断这样穿过本发明的百叶式流体动力 装置， 不断带动轮叶 1进而带动轮轴 2转动， 川流不息， 以产生动能， 轮轴 2所产生的动能都可以向外输出用于发电。 本发明的百叶式流体动力装置的能量损耗主要在四部分： 1)轮轴 2的机械摩擦力； 2)轮叶 1进入逆流区 12时翻开窗叶 3所耗损的能量； 3) 轮叶 1在逆流区 12回转时轮叶骨架 7的实际面积阻挡流体所耗损 的能量； 4)本发明的百叶式流体动力装置本身所具整体质量在转动中 的耗能。
以上四部分能量损耗接近固定， 按理， 在强风的气流中或在河流 或洋流的巨大能量作用力下， 流体穿过本发明的百叶式流体动力装置 带动轮叶 1 旋转所产生的能量， 远超过能量损耗， 抵消能量损耗后， 还有大量剩余能量， 以带动发电机组发电。
下面是对本发明的百叶式流体动力装置所产生的能量通过初歩估 算进行说明：
假设轮叶 1的径向长度为 R， 假设轮叶 1的轴向长度为 L， 轮叶 1 的面积为 RL。假设流体依转向面 13方向流过 r的距离所用的时间为 t， 则流体速度 v=r/t。 流体密度为 P。
初歩估算功率 P=(l/2)mv2/t=(l/2) P rRLv2/t=(l/2) P RLv3。
若置于水流中， 水密度 P=1000Kg/m3。
假设 R为 1米， 轮叶的长 L=1000米， 水流速度 V为 1米 /秒， 功 率？=(1/2) 1000 1 1000 13=0.5百万瓦。 同样的装置， 若置于水 流速度 V 为 3 米 /秒的水流中， 则功率 P= (1/2) X 1000X 1 X 1000 X 33=13.5百万瓦。
若置于强风中， 空气密度 P=0.225Kg/m3。
假设 R为 1米， 轮叶的长 L=100米， 风速 V为 10米 /秒时， 功率 P=(1/2) X0.225X 1X 100X 103=11.2千瓦。 同样的装置， 若置于风速 v 为 20米 /秒的强风中， 功率 P=(l/2) X0.225X 1 X 100 X 203=90千瓦。
发电容量比较： 三峡大坝水电站， 共安装 32台 70万千瓦水轮发电机组， 另外还 有两台 5万千瓦的电源机组， 总装机容量为 2250万千瓦， 即 22500百 万瓦。 长江中游长一千公里， 平均流速为 1米 /秒， 可设置数万个轮叶 径向长度 1米及轴向长度 1000米的百叶式流体动力装置在河流中， 发 电量可超过三峡大坝水电站的发电量。长江上游的水流速度达 3米 /秒， 同一装置的发电量更提升十数倍。 事实上， 长江流域年均水资源总量 9960亿立方米，全流域水能理论蕴藏量约 2. 8亿千瓦，可开发量约 2. 6 亿千瓦， 约为三峡大坝水电站发电量的 11倍， 若能够发挥一半功效已 有 5倍三峡大坝水电站的发电量。
另外， 洋流能源更为巨大， 中国沿海洋流的理论平均功率为 1. 4 亿千瓦。 美国墨西哥湾流总流量便达到 7400〜9300万立方米 /秒， 比 陆地上所有河流的总量则要超出 80倍。 若与我国的河流相比， 它大约 相当于长江流量的 2600倍， 或黄河的 57000倍。 美国伍兹霍尔海洋研 究所的研究人员指出， 墨西哥湾流受到风力、 地球自转和朝向北极前 进的热量所驱使， 所带来的能量等同于美国发电能力的 2000倍。
世界上河流洋流能量资源丰富， 若考虑全世界河流洋流适当设置 本发明的百叶式流体动力装置， 所产生的发电量， 足可以取代现有所 有火力发电及核能发电设施， 大大减少因火力发电排出的废气所带给 人类的危害， 并同时能大大减少核电泄露辐射所存在的危险。 以上实施例仅为本发明的示例性实施例， 不用于限制本发明， 本 发明的保护范围由权利要求书限定。 本领域技术人员可以在本发明的 实质和保护范围内， 对本发明做出各种修改或等同替换， 这种修改或 等同替换也应视为落在本发明的保护范围内。
