The energy efficiency control valve I 15 is in the open state, and water flows through the pressure water pipeline I 2 into the water outlet pipe I 3, driving the runner I 4 to rotate, and then driving the generator set 1 to generate electricity. When a large amount of power generation is required, the energy efficiency control valve II 16 and the energy efficiency control valve III 17 are opened, and the vertical pressure pipeline 6, the pressure water pipeline II 7, and the pressure water pipeline III 8 are connected to the pressure water pipeline I 2. Due to the greater water flow drop and faster water flow velocity in the pressure water pipeline II 7 and the pressure water pipeline III 8, the runners II and III 11 and 12 rotate faster, thereby increasing the power generation. The ecological unit energy efficiency control device of the present utility model is provided with multiple pressure water pipelines with different drops, and energy efficiency control valves are arranged on the pressure water pipelines, which is convenient for controlling the water flow rate and velocity, thereby controlling the rotation speed of the runner, and then controlling the power generation efficiency. By setting runners at different heights, it is convenient to generate electricity using water flows with different drops. By arranging a transmission mechanism between the runners, it is convenient for the lower runner to drive the higher runner to rotate, and then drive the rotor of the generator set to rotate for power generation, while reducing the influence of the lower runner on the higher runner when there is no water in the lower pipeline. As an alternative, the lower end of the runner III 12 can also be drivingly connected to a runner IV.
