Embodiment

The utility model will be further described below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises casing 1, be arranged at main shaft 2 in the casing 1, be arranged on the main bearing 14 on the main shaft 2 and be arranged on the turbine blade 9 of main shaft 2 bottoms.Above casing 1, the cylindrical of pressing close to main shaft 2 is provided with limit casing 3, and the outside of described limit casing 3 has been horizontally disposed with two groups of four Limit Bearings 4, and the outer ring of described Limit Bearing 4 is pressed against on the cylindrical of limit casing 3, and its inner ring is connected on the casing 1; The arranged outside of described casing 1 inner main axis 2 has main spindle quill 13, described main spindle quill 13 is a drive fit with main shaft 2, and its top is provided with liquid control mill 5, and its upper end is supported on the below of main bearing 14, its arranged outside has upper water sleeve pipe 15, and the arranged outside of upper water sleeve pipe 15 has seal water pipe 16; Leave the gap between described main spindle quill 13 and the upper water sleeve pipe 15, be provided with spiral-shaped water guide blade 6 between described upper water sleeve pipe 15 and the seal water pipe 16, a side of described water guide blade 6 is provided with valve 7, and described valve 7 is connected on the screw rod control switch 8; The outer of described turbine blade 9 is connected with the inwall of water wheels outer ring 17, and described water wheels outer ring 17 is provided with water shutoff outer 18, and described water shutoff outer 18 is arranged in the ring for the sealing liquid 10, and described ring for the sealing liquid 10 is arranged on the lower end of seal water pipe 16; The lower end of described main shaft 2 is arranged in the center tube 12, and the cylindrical of main shaft 2 lower ends is provided with spiral helicine pushing gas vane 11.

During the utility model work, current have water inlet 20 to enter in the casing 1, and rotating screw bolt control switch 8 drives valve 7 and moves up and down, thus the current size that control enters water guide blade 6; Because Limit Bearing 4 is by limit casing 3, radially giving main shaft 2 certain side pressure, reduce the running clearance of main shaft 2, eliminated swing radially when main shaft 2 rotates; Because the reaction force of water, part water promote liquid control mill 5 upwards along rising on the space between main spindle quill 13 and the upper water sleeve pipe 15, drive main spindle quill 13 and make progress that supports main shaft holds 14, main shaft 2, thereby reduced the mechanical wear of bringing because of the weight of main shaft 2; The setting of water guide blade 6, the guiding water inlet forms eddy current, has increased the impulse force to turbine blade 9; The setting of water wheels outer ring 17, water shutoff outer 18 and ring for the sealing liquid 10 has reduced the leakage of working flow, has improved the utilization and the work efficiency of the energy; Because the setting of center tube 12 and pushing gas vane 11 can make down the air in sluicing discharge as early as possible, reduces rotational resistance, has been equivalent to increase the pressure of upstream current, also is equivalent to increase the water level of upstream.
