step three: when the power of the power generation mechanism needs to be adjusted, the adjusting mechanism moves at the moment, and the guide vane (24) is driven to rotate through the second rotating rod (23), so that the movement track of the water flow is changed, and the power generation power of the power generation mechanism is adjusted.
