Description

无落差长叶柱状水轮机
技术领域
本实用新型涉及水力发电装置，特别是水轮机。
背景技术
现有的水力发电需要有一定的水位落差，要在江河上建造拦河大坝，抬高水位，提高水头。当前，国内外的中高水头的水力发电，开发得所剩无几。现有的水下发电机用水轮机，如专利申请号01129559.7公开了一种利用海洋波浪能量驱动水下泵排水，实现海水在有一定落差的条件下形成海水循环，达到驱动水轮机发电。它只能采用水的落差驱动水轮机发电，而不能利用水下水流动驱动水轮机发电。
发明内容
本实用新型的目的在于提供一种利用结构简单、造价低、安装容易的无落差长叶柱状水轮机。
本实用新型由以下技术方案完成，它包括聚流罩、导流管，导流管为圆筒状，聚流罩为喇叭口形，设在导流管的进水口，在导流管中设有转轮轴及轴承和轴承座，在转轮轴上设有水轮机叶片，水轮机叶片前端设有泄水锥，转轮轴通过传动主轴与发电机相连接。
本实用新型为长叶柱状水轮机，水轮机的叶片为加长形的叶片，当无落差的水流进入到喇叭状的聚流加速管后，其单位的体积和流速都依现场的工况比例得到增大。在经过水轮机的加长形的叶片后与叶片产生相对的力，推动叶片作旋转运动，在水流不断的情况下，依照水轮机的相似律，得到和水力试验模型近似的转速和转矩。当流水在水轮机叶片上脱离质点时，由于受到喇叭口上游进水的压力，使水轮机作恒速运转而发电
本实用新型水轮机能在无落差水流的流速缓、流量大的情况下获得较大的转矩，再选用适配的增速箱和发电机即可用于发电，与风力发电相比具有成本低、应用范围广的特点，能产生巨大的经济效益和社会效益。本实用新型还具有成本低，结构简单，安全可靠的特点。
附图说明
图1为本实用新型结构示意图；
图2为图1的A-A剖示图；
图3为图1的轴承座结构示意图。
具体实施例
附图为本实用新型的一个具体实施例，它包括包括聚流罩1、导流管8、导流管8为圆筒状，聚流罩1为喇叭口形，聚流罩设在导流管8的进水口，在导流管中设有转轮轴5及轴承及轴承座4，在转轮轴5上设有水轮机叶片3，水轮机叶片3前端设有泄水锥2，转轮轴5通过传动主轴6与发电机相连接。
