Description

简易合口式水浪发电机
技术领域
本发明涉及用于水中波浪发电的发电机，特别是一种简易合口式水浪发电机。
背景技术
已有的波浪发电技术是采用在浮力筒四周安装叶片，让波浪冲击叶片下部，叶片在波浪冲击下转动，带动与浮力筒相连的发电机进行转动发电。由于波浪会随着外部天气变化发生变化，有时高，有时低，当波浪不仅打在叶片下面，同时也打在叶片上方，这样，叶片所获得转动力矩变小，使得发电机吸收能量也相应变小，发电效率相应降低，因而现有波浪发电技术只能吸收小量波浪的能量，而没有对大量波浪加以利用。
发明内容
本发明所要解决的技术问题是，针对现有技术不足，提供一种既能吸收大量波浪能量的简易合口式水浪发电机。
为解决上述技术问题，本发明采用的技术方案是：一种简易合口式水浪发电机，其包括与电力输送装置连接的发电机组和合口部分，发电机组包括发电机，该发电机的输入轴通过联轴器连接带有叶片的叶片轴；合口部分包括用于引水水浪并传送水浪的合口，该合口的一端设有朝向水浪的进水口，另一端的出水口一体连通直口的一端，且该合口的横截面积从进水口端至连通直口处逐渐减小，直口的另一端出口处设置带有叶片的叶片轴，直口内部空芯，合口和直口分别通过固定设置在水浪里的支柱支撑。
上述方案的进一步改进为，所述合口整体设置在水浪中，使直口与合口相连通，直口的尾部伸出水面。
上述方案的进一步改进为，所述叶片轴的设置位置与直口的一侧边界相平齐，这样直口出来的水只冲击到二分之一的叶片，使叶片轴的两侧叶片受力相差较大，形成大扭矩，而使叶片轴加速旋转，从而将这种加速转动的力传递给发电机的输入轴，使发电机的发力效率相应提高。
上述方案的进一步改进为，所述直口的尾部竖直设置支承柱，所述发电机及叶片轴固定安装在支承柱上。
上述方案的进一步改进为，所述简易合口式水浪发电机还包括风力发电机，且所述风力发电机与简易合口式水浪发电机同时与所述电力输送装置连接。
本发明简易合口式水浪发电机的工作原理为：本发明合口前端进水口处横截面积大，后端直口连接处的横截面积小，因而能将进水口处大量低速的波浪收集到出口很小的合口尾部；由于合口的出口很小，因而其水流速度将会加快，合口末端高速水流经直口冲击与发电机的输入轴连接的叶片轴的叶片，将使发电机获得很大的能量。
由于本发明的合口可以做得足够大，因而可以将大量的水波浪能收集起来发电，且合口的横截面积不断缩小，具有提升波浪速度的作用，因而也可以将其它水面的相对较小的水波浪能收集起来发电。由于水浪无需成本，同时，由于海浪具有随日出、季风等出现潮涨潮落的状况，因而水浪持续时间长，源源不断，使得本发明发电机可持续发电。
附图说明
图1为本发明简易合口式水浪发电机第一实施例结构示意图。
图2为图1的K向结构示意图。
图3为本发明发电机组的结构示意图。
图4为本发明合口式水浪发电机第二实施例直口设置状况示意图。
具体实施方式
如图1至图3所示，本发明简易合口式水浪发电机第一实施例包括发电机组1和合口部分2。发电机组1包括发电机11、联轴器12、叶片13、叶片轴14、轴承座15和螺母16，其中，叶片13设置于合口部分2的输出端，叶片轴14与发电机11的输入轴通过联轴器12连接固定，叶片轴14的输出端设置两个轴承座15，两轴承座15固定在合口部分1的支承柱231上，叶片13固定安装于叶片轴14上，叶片轴14的底部经螺母16锁定。合口部分2包括合口21、支柱22和直口23，支柱22为多根，且多根支柱22的一端固定设置在水里，另一端支承在合口21的支承部位或直口23的支承部位，合口21的尾部与直口23的入口连接为一体（如图2中合口21进入直口23的孔P所示），合口21的进口端设置敞口状的进水口，且该进水口设置在水中，进水口的开口面积大，但与直口23相联的尾部出口面积小，即合口21的开口端至尾端的横截面积呈现为逐渐缩小状，合口21整体设置在水中，使直口23与合口21相连处在水中，直口23的尾部伸出水面，且直口23的尾部开口处设置叶片13，叶片轴14的设置位置与直口23的一边平齐，直口23的尾部还竖直设有支承柱231，发电机11及叶片轴14通过螺栓24固定在支承柱231上。
当水从合口21的进水口进入合口21后，从合口21的尾部进入直口23，再从直口23尾部的开口处出来。在此过程中，由于合口21的进水口的过水面积比较大，中间逐渐收小，直至合口21的尾部，使合口尾部的过水面积最小；当比较慢速的水进入合口21的进水口，由于进水口面积大，所以，在流量一定情况下，由于合口21尾部的出口面积（过水面积）比较小，使合口21尾部出口水的流速加大，即水流以高速进入直口23，由于直口23从头至尾的口径不变，因而这些快速流动的水直接冲击直口出口处的叶片13，叶片13带动叶片轴14转动从而带动发电机11的输入轴转动实现发电。
本发明并不局限于以上形式，比如直口23的延伸方向不仅如上所示可向上设置，也可进行水平或向下延伸；另外如图4所示，本发明中的直口23可设备两个，装有发电机11的直口23前方也可设置闸门，而另一直口23后面接有水管，该水管连通高处的储水池，在不需要发电时，关闭发电机11前方的闸门，同时，打开另一直口23上的常闭闸门3，这样，发电机11不发电，另一直口23后水管内的水压增加，水可流进储水池；合口21的横截面也可为其它形状；本发明也可不设置直口23，而合口21出水口比进水口小，发电机组1直接安装在合口21上，由合口21出水口的水带动叶片13转动；合口21的开口端至尾端的横截面积相等；本发明也可在两个直口23的出口处都安装有发电机组1。
本发明的发电机组1和合口部分2都可设置为多个，可一个发电机组1配合多个合口部分2，也可一个发电机组1与一个合口部分2相配合，形成多组结构，多组结构可分层设置，也可水平并列设置。
本发明也可与风力发电机相接合而使用。
上述实施例仅用来例举本发明的实施态样，以及阐释本发明的技术特征，并非用来限制本发明的范畴。任何熟悉此技术者可轻易完成的改变或均等性的安排均属于本发明所保护范围内。
