When the water flows through the water outlet section 14 of the first rotating tube 10, it will drive the first rotating tube 10 to rotate, thereby driving the first helical gear 32 to rotate, thereby driving the second helical gear 34 to rotate, and finally making the first generator 50 to rotate generate electricity.

The second rotating tube 20 is made up of a connected expansion section 21 and a conventional section 22.
