Because the water outlet direction of the emptying pipe has a plurality of modes, the principle of the relative position of the pressure water inlet pipe 8 and the emptying pipe 7 is that the two are matched with the impeller of the hydraulic turbine and are also matched with each other, and the phenomenon of water blockage or water blocking is not allowed to occur.
As shown in fig. 2, the water outlet direction of the emptying pipe 7 and the water inlet direction of the pressure water inlet pipe 8 are coaxial. As shown in fig. 3, the direction of the water outlet of the evacuation pipe 7 is located above the hydraulic turbine 1.
The water outlet direction of the emptying pipe 7 and the water inlet direction of the pressure water inlet pipe 8 can also be the same horizontal direction.

A toggle switch (not shown in the figure) is also installed on the speed reducing unit 2 and is used for converting hydraulic drive control or hand wheel control. Although the hand wheel 6 is located on the right side of the reduction unit 2 in fig. 1, it is obvious that both the hydraulic drive and the hand wheel drive can be conveniently driven without affecting each other. As shown in fig. 4, the pressurized water inlet pipe 8 and the emptying pipe 7 are positioned in a coaxial and same-side mode, and the hydro turbine 1 and the hand wheel 6 are positioned in an optimal position relation on the left side and the right side of the speed reducer unit 2. As shown in fig. 5, when the evacuation pipe is positioned directly above the hydro turbine, the hydro turbine 1 is positioned above the reduction gear unit 2, and the hand wheel 6 is mounted on the side of the reduction gear unit in an optimum positional relationship.
