Embodiment:
A kind of double-cable type wind-driven generator is equipped with 12, two main rope of a plurality of sub-power generation systems 2 and connects by rigidity connecting rod 4 on two main rope 2, preceding blower fan 8 and rear fan 9 relative installation on same rigidity connecting rod 4 in the sub-power generation system 12.Two main rope 2 tops are also parallel to be equipped with two secondary ropes 1, and secondary rope 1 and main rope 2 are connected by track cable, and secondary rope 1 can be used as the usefulness of installation, maintenance.
Blower fan 8 and rear fan 9 relative installations before in the sub-power generation system 12.Fan shaft 11 is provided with a plurality of blade connecting rods 10 in preceding blower fan 8 and/or the rear fan 9, be provided with the pitched device in the fan shaft 11, the pitched device is connected with blade connecting rod 10, and blade connecting rod 10 is provided with blade 3, and fan shaft 11 is connected with generator 6 by transmission system 13.The generator 6 of preceding blower fan 8 and/or rear fan 9 all is fixedly mounted in the rigid sleeve 7, and rigid sleeve 7 is installed on the rigidity connecting rod 4 by fixed card 14.Secondary rope 15 is installed in parallel in below the generator 6 with main rope 2, and the generator cable 5 of drawing is sent to transformation base station, ground along secondary rope 15, carries out rectification, the back of boosting transmits electric power to electrical network.The actuating cable 16 of regulating and controlling blade connecting rod 10 slurry distances, the pitched device of blower fan 8 and rear fan 9 before also being connected to by transmission rope 15.
When wind forwards, backwards during two fan blades 3, because blade 3 is certain inclination angle, wind-force makes its rotation, preceding blower fan 8 is installed slurry apart from opposite with the blade 3 of rear fan 9, before blower fan 8 opposite with the sense of rotation of rear fan 9, the rotational speed of two generators 6, output power is identical, moment of torsion is identical, but torque direction is opposite, these two axial moments of torsion are cancelled out each other on rigid sleeve 7, thereby in sub-power generation system 12, obtained static equilibrium, even produce small moment of torsion, also can be overcome with being connected of main rope 2 by the T junction 17 at 4 two ends on the rigidity connecting rod, two main rope 2 only need be born equipment gravity and wind-force, so two main rope 2 are relatively stable.Because of after wind makes its rotation through preceding blower fan 8, the moment of torsion that produces on rear fan 9 can be less, can make by the pitch of blower fan 8 before regulating and rear fan 9 its have small difference in order to balance before moment of torsion between blower fan 8 and the rear fan 9.
When wind speed changed, by the connecting rod 10 slurry distances of blower fan before the synchronization regulation 8 with rear fan 9 blades 3, blower fan 8 kept stable with the rotating speed of rear fan 9 before can making, thereby obtains stable electric current.
Same principle when wind direction is next from oppositely blowing over, also can make two blower fans obtain stable rotating speed by the slurry distance of blower fan before the synchronization regulation 8 with rear fan 9.
