Description

蓄水式水轮机进水落差井
技术领域    
本发明是水轮机的一种进水落差井设计方案。
背景技术   
现有的水轮机进水落差井通常为斜坡型或垂直型管状通道,它存在容积受限导致水压受限,既无法容纳即利用峰谷期超量水流而浪费水力资源、又不能利用该超量水流增强水压以增强水能功率的不足。
发明内容   
本发明目的是针对现有技术以上所有不足提供一种蓄水式水轮机进水落差井。蓄水式水轮机进水落差井,包括水轮机地平线之下的进水口与进水落差井底端相通;该进水落差井另包括在水轮机旁设置高度与其相等、体积大于两倍、底端侧壁与水轮机进水口相通的蓄水腔,该蓄水腔有蓄水腔落差井其顶端与河流相通,底端穿入蓄水腔底端附近侧壁接近水轮机,与水轮机进水口和蓄水腔底端相通;该蓄水腔顶端设含多个排气孔的活动盖板或设随水升降的种植浮框。
从上述设计可见,蓄水腔落差井起从水轮机另端进水口向水轮机提供水能、形成双落差水压的作用。蓄水腔起蓄积来不及冲入水轮机进水口的水流至河流上层水位线,等同于再增高一倍河床落差,成倍的增强进水落差井水压和该落差出口流速、成倍增强水能功率、避免浪费峰谷期水力资源而提高电站发电效益、可降低沿河电站落差而多建电站的作用。该蓄水腔顶端可设含多个排气孔的活动盖板,起增加房屋使用面积的作用,其中排气孔起蓄水过程排出腔内空气的作用。该蓄水腔可设随水升降的种植浮框,起种植葱蒜蔬菜方便烹饪调味、填补蓄水腔占地面积的作用。 
与现有技术比,它有费省效宏、既成倍增大水能功率、又充分利用峰谷期水力资源、可降低沿河电站落差而多建电站的优点。
