Figure 3 As shown, each turbine 3 is tilted at a certain angle, and a turbine driving mechanism is arranged above the two turbines 3 to rotate the two turbines 3 at the same time.

[0023] Please combine Figure 2 As shown, the turbine drive mechanism includes a No. 1 servo motor 9 fixedly connected to the upper end of the load-bearing plate 10, and the output end of the No. 1 servo motor 9 is fixedly connected to a No. 1 worm gear 8, and the two sides of the No. 1 worm gear 8 are respectively engaged with the two turbines 3 at the same time.
