Embodiment 1
[0019] Embodiment 1: as figure 1 , 2 As shown in . and 3, a paddle turbine blade operating mechanism includes a runner body 1, at least three blades 2 are arranged on the runner body 1, and water turbines are respectively arranged at both ends of the runner body 1. The main shaft 3 and the drain cone 4 are provided in the runner body 1 with an operating oil pipe whose end passes through the main shaft 3 of the water turbine and penetrates into the runner body 1, and an oil inlet and outlet mechanism is arranged on the penetrating end of the operating oil pipe. A super relay mechanism communicating with the oil inlet and outlet mechanism is arranged on the oil inlet and outlet mechanism, and the super relay mechanism is connected with the blade 2 through the slider 5 and the rocker arm 6 .
[0020] Wherein, the operating oil pipe includes the operating oil pipe A8 and the operating oil pipe B9; the oil inlet and outlet mechanism includes the oil receiving shaft 10, and the oil...
Embodiment 2
[0026] Embodiment 2: as Figure 4 As shown, the section of the super servomotor cylinder 18 is square, and four chutes 23 are evenly arranged on the super servomotor cylinder 18; Inside the chute 23 ; there are four blades 2 , and each slider 5 is connected to the corresponding blade 2 through a rocker arm 6 .
Embodiment 3
[0027] Embodiment 3: as Figure 5 As shown, the section of the super servomotor cylinder 18 is pentagonal, and five chutes 23 are evenly arranged on the super servomotor cylinder 18; There are five slide slots 23; there are five blades 2, and each slider 5 is connected to the corresponding blade 2 through a rocker arm 6, respectively.
[0028] Of course, according to actual needs, the super servomotor cylinder 18 can also be made into a hexagonal or octagonal shape, and the corresponding blades 2 can also adopt six blades or eight blades.
