Description

低水头发电水轮机
本发明提供了一种低水头发电水轮机,尤其是一种堵截性使用做功水流截面,可扩大使用做功水流静压、成倍缩小做功流量损耗投资少,又不少做功的低水头发电水轮机。
目前各种水轮机在做功过程中,都是依靠使用动能做功为主,其致命弱点是转轮做功不能和水流同步,做功转轮正常做功的速度使用水流速
Figure A9810169700031
力就要被同步丢失,只等于余下 力的 速度功率,再加上斜面受力等分力损失,所以能量利用效率,从水量损耗分析,原有水轮机所为利用效率8%它是以纯动能损耗流量为代价的,因此本发明纠正了这个弱点,利用五到八米的水头就能提高一倍能量利用效率,并且低水头电站使用其它水轮机就型体大投资多了。
下面对本发明结构原理的组成详细叙述说明书附图,为本发明结构原理组成图。
支承柱9装配在装置固定架1上,支承柱9上再装配链轮7,链轮7上装配链条6,链条6上装配挡水板5,装置固定架1上再装配压力水管4,这样,当水流从水平面2进入进水口3到压力水管4中形成挡水板5受质运动后,就会带动链轮7运转,并带动运转轴8传动发电机做功。

Claims (2)

1.本发明提供了一种低水头发电水轮机、其结构原理由:链轮7,链条6,挡水板5压力水管4,组成;
2.根据权利要求1所述的装置,其特征在于,由挡水板5和压力水管4的结构组合,形成了堵截性使用做功水流截面,在能够利用速比多用水压的条件下所致功能减少压力增大,实现了节约做功能量又设备投资少的目的。
