本发明的工作原理为：
与侧推动轮转式发电机组工作原理不同，本发明公开一种双轴双向变角塔轮，密封进水端盖2密封住外筒1顶端，落水自进水口3、密封进水端盖2落入 外筒1内，依次冲击第一叶轮组5和第二叶轮组7，所述第一叶轮组5由若干个第一叶轮单元51连接而成，通过相邻的上固定环52、下固定环53上的安装孔54实现若干个第一叶轮单元51之间的连接，安装于第一叶轮安装室内的第一叶轮57与套管4底端连接，第一叶轮57边沿端固定连接于支撑柱56上，从而实现第一叶轮57与叶轮筒50内壁之间的一体式设置，当进水通道内的落水冲击第一叶轮57时，带动与第一叶轮57连接的套管4、以及与第一叶轮57连接的叶轮筒50正向转动，与套管4顶端连接的第一锥齿轮81输出该正向转动力，所述叶轮筒50侧端开设有呈螺旋状设置的镂空部55，减少叶轮筒50自重的同时，减少叶轮筒50外壁与外筒1内壁的接触面积，防止两者产生自吸力，干涉套管4的正向转动，所述第二叶轮组7位于第二叶轮安装室内，第二叶轮组7等数量于第一叶轮组5设置，第二叶轮组7通过叶轮安装部71连接于中心轴杆6上，落水经过叶片72上表面的流道，从而驱动第二叶轮组7带动中心轴杆6反向转动，与中心轴杆6顶端连接的第二锥齿轮82输出该反向转动力，最终落水自外筒1底端排出，与套管4顶端连接的第一锥齿轮81以及与中心轴杆6顶端连接的第二锥齿轮82形成了正向和反向两个不同转向的双轴双向输出形式。
本发明的有益效果为：
第一叶轮组5与第二叶轮组7在外筒1内依次间隔排布(即第一叶轮组5按奇数顺序排布于外筒1内，第二叶轮组7按偶数顺序排布于外筒1内)，落水进入进水通道内时，与位于奇数层的第一叶轮组5连接的套管4朝一个方向转动，与位于偶数层的第二叶轮组7连接的中心轴杆6朝向另一个方向转动，从而使套管4和中心轴杆6转向相反，形成“双轴同心的双向”的输出方式，正向和反向两个不同转向的双轴双向输出形式，产生两个方向的旋转力，第一 叶轮组5和第二叶轮组7的相对运动使运动旋转速度大幅提高，而旋转速度是能量转换的重要条件，通过变速箱改变动力输出端的受力方向并调整转速带动发电机旋转，达到切割磁力线来发电的目的。因此，水位差在30-50米的落水即可实现高效率发电，无需大水位落差，建设成本降低的同时，水利用高。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
