Description

一种水力发电装置 技术领域
本发明是涉及水力发电技术，具体说，是涉及一种水力发电装置。
背景技术
众所周知，水资源是宝贵的清洁可再生资源，可以作为解决能源制约的长效手段。目前水力发电的原理主要是利用水位差产生的强大水流所具有的动能推动水轮机带动发电机组而发电。现在基本上都是采用螺旋桨叶式进行水力发电，如：美国在水里安装直径达70米的螺旋浆发电，利用水流推动螺旋浆旋转，带动发电机发电。但这种螺旋浆旋转的发电方法具有制造成本高的缺点，特别是桨叶边缘的线速度高、阻力大，存在水能转化率低的难题。以直径为70米、转速为10r/m的螺旋浆为例：桨叶的边缘线速度达到36.6米/秒，相当于121公里/小时的水阻力。这种水阻力的存在会极大地消耗水流自身的动能，导致发电量减少。为什么不用叶轮发电？因为当叶轮在水力推动下旋转时，轮轴的上方叶片与下方叶片的旋转方向是相反的，这种相反旋转就会相互抵销推动力，导致能耗大、发电效率低、发电成本高，没有实用价值。
发明内容
针对现有技术存在的上述问题，本发明的目的是提供一种水力发电装置，以低成本、低能耗、高效率实现水力发电，以促使水力资源的规模化应用。
为实现上述目的，本发明采用如下技术方案：
一种水力发电装置，包括叶轮和叶轮轴，所述叶轮包括叶片，其特征在于：所述叶轮的安装需使构成叶轮的部分叶片处在空气中，而余下叶片处在水流中。
本发明将与水流方向相反的上部叶片放置在空气中，由于空气的比重只有水的八百分之一，并且空气是相对静止的，这样，当上部叶片进行反向旋转时，所受的空气阻力远远小于水流所产生的阻力，从而可大幅度降低水能的损耗，提高水流发电效率。
作为优选方案，使处在空气中的叶片与处在水流中的叶片成中心对称分布。这种对称分布可以使水里的叶片尽量浸没在水流中，能受到最大水能作用。
作为优选方案，所述叶片为弧形叶片。当弧形叶片与水流方向相对时，可获得更大的水流推动力。
作为进一步优选方案，在弧形叶片的两端设有挡板。在弧形叶片的两端设置挡板，可将两端的水流锁住，提高水能的利用率。
作为进一步优选方案，在所述挡板上设置传动轮，所述传动轮与发电机相连接。
作为进一步优选方案，所述弧形叶片上设有至少一块分隔板，使所述弧形叶片被分隔为多段。通过分隔板的阻挡作用，可将水流锁住在隔离区内，防止水流扩散，提高水能的利用效率。
作为优选方案，所述水力发电装置还包括U形束水槽，叶轮位于所述U形束水槽内。通过束水槽的束流作用，可以防止水流在推动叶片时，不会向其它方向扩散，以致水流的动力仅限于叶轮的旋转方向，从而进一步提高水能的利用效率。
作为优选方案，在所述叶轮的前端设有导流罩，所述导流罩的口径由大变小，在进水口处为大口径，在叶轮的前端处是小口径。通过导流罩的导流作用，将更多的水流引入到水力发电机里，从而可提高水力发电机的工作效率。如：叶轮的进水口是5米×20米，现在通过导流罩的作用，导流罩的进水口的尺寸是15米×20米，宽度与原来一样，但高度是原来的三倍；导流罩的出水口仍然是5米×20米，与叶轮的进水口相同，并与之相接。通过导流罩的导流作用，将15米×20米的水能引入到5米×20米，进水量增加了三倍，从而大大提高了可发电的水能。
作为进一步优选方案，在所述导流罩上设有开合门。通过开合门的开启或关闭作用，可不断调整进水量的大小，使流量处于相对稳定的状态，从而保证所发电的品质。
作为进一步优选方案，所述导流罩的后端与U形束水槽的前端连接为一体。这种连接可以保证两者合二为一，可增加安装的方便性和降低制造成本。
作为优选方案，在所述叶轮轴上安装有至少一个输出轮，所述输出轮具有离合功能。水流的大小是不断变化的，通过在叶轮轴上安装一个或一个以上的动力传输轮，当水流变小时，通过离合连接功能使其中的部分动力传输轮分离，从而减少发电负荷，保证发电品质；同样，当水流变大时，使其中的动力传输轮连接上，增加发电负荷，从而充分利用水流发电，并保证发电品质。
作为优选方案，在所述叶轮轴的中部垂直设有水流方向调节轴，所述水流方向调节轴能根据水流方向变化自动调节叶轮轴与水流方向保持垂直，从而提高水力发电效率。
作为优选方案，在所述叶轮上或叶轮轴上或水流方向调节轴上设有导向舵。一旦水流方向改变，导向舵会在水流作用下，调节叶片方向与水流方向保持垂直，从而提高水力发电效率。
与现有技术相比，本发明具有如下有益效果：
本发明通过使构成叶轮的部分叶片处在空气中，余下叶片处在水流中，从而使旋转方向与水流方向相反的叶片不再受到水流的反向阻力而只是空气阻力，由于空气阻力远远小于水流所产生的阻力，因而本发明可大幅度降低水能的损耗，提高水流发电效率，经计算，发电效率相对于现有的螺旋桨发电，至少可提高一倍以上；尤其是，当在叶轮前端设置导流罩时，可将水能利用率提高到现有的二倍以上；因此，本发明可低成本、低能耗、高效率实现高品质的水力发电，对促使水流资源的规模化应用具有重要价值。

具体实施方式
下面结合实施例和附图对本发明的技术方案作进一步详细阐述：
实施例1
如图1所示，本实施例提供的一种水力发电装置，包括叶轮1和叶轮轴2，所述叶轮1包括叶片3，其特征在于：所述叶轮1的安装需使构成叶轮1的部分叶片3A处在空气中，而余下叶片3B处在水流中。
作为优选方案，使叶轮轴2的中心位于水平面4上，从而使处在空气中的叶片3A与处在水流中的叶片3B构成中心对称分布。
当水流5推动处在水流中的叶片3B时，叶片3B带动叶轮轴2旋转，产生旋转动力，可用于发电。虽然处在空气中的叶片3A会产生同步旋转，但在旋转过程中只受空气阻力，而空气是静态，尤其是，空气的比重只有水的八百分之一，因而叶片3A所受的空气阻力远远 小于水流所产生的阻力，因而相对于现有技术(叶片全部处于水流中)，可大幅度降低水能的损耗，提高水流发电效率。
实施例2
如图2所示，本实施例提供的水力发电装置，与实施例1提供的水力发电装置的不同之处在于：所述叶片3为弧形叶片，使处在水流中的叶片3B的弧形凹槽是迎流而设，而处在空气中的叶片3A的弧形凹槽是背流而设，这样可使处在水流中的叶片3B相对于直形叶片能接受更大的水流作用，而处在空气中的叶片3A所受阻力更小，从而水能损失更小，可比实施例1进一步提高水能的利用率。
实施例3
如图3所示，本实施例提供的水力发电装置，与实施例2的不同之处在于：在所述弧形叶片3的两端设有挡板6，在两挡板之间设有多块(图3中示出了3块)分隔板7，所述弧形叶片3被分隔成四段，每段的空间只有原来的四分之一。当水流冲向弧形叶片3时，不仅在挡板6的作用下，可将两端的水流锁住，而且通过分隔板7的作用，将横向扩散的水流也进行了锁定，从而相对于实施例2，本实施例可进一步提高水能的利用率。
实施例4
如图4所示，本实施例提供的水力发电装置，与实施例3的不同之处在于：在垂直固定于支撑面8的水流方向调节轴9的下端设有平面轴承10，在平面轴承10的两侧对称设有叶轮1，在所述叶轮1的叶片3两端设有挡板6，在两挡板之间设有多块(图4中示出了3块)分隔板7，所述叶片3均被分隔成四段；在所述平面轴承10的下方设有导向舵11，导向舵11与叶片3垂直，导向舵11在转动时会带动叶片3水平同步转动。当水流方向发生改变时，导向舵11会受到水流作用产生旋转，在旋转时会通过平面轴承10带动叶片3也同步旋转，从而始终保持与水流方向垂直旋转，获得最大的水能。
实施例5
如图5所示，本实施例提供的水力发电装置，与实施例1提供的水力发电装置的不同之处在于：在叶轮1的前端安装了导流罩12，所述导流罩12呈收缩式喇叭形状，在进水口处为大口径，在叶轮1的前端处是小口径，当水流5进入导流罩12后，随着导流罩12的面积逐渐缩小，水流5的水能会逐渐变大，从而可提高水力发电的效率。如：当导流罩12的面积缩小一倍时，水能会提高一倍，一个水力发电机的发电效率相当于原来两个水力发电机的发电效率。
实施例6
如图6所示，本实施例提供的水力发电装置，与实施例2的不同之处在于：在处在水流中的叶片3B的外周设置U形束水槽13，U形束水槽13的开口端为进水端，U形束水槽13可使冲向处在水流中的叶片3B的水流被束缚在U形束水槽13内，避免水流向四周扩散而损失，从而可进一步提高水能的利用率。
当然，U形束水槽13可以与导流罩12(本图中未画出)连接成一个整体，以便加工和安装，降低制造成本。
最后需要在此指出的是：以上仅是本发明的部分优选应用例，不能理解为对本发明保护范围的限制，本领域的技术人员根据本发明的上述内容做出的一些非本质的改进和调整均属于本发明的保护范围。
