Flanged (FLGD) steel-tube construction.The steel platform 301 is both the antitorque platform of the platform, sometimes tower 30 of installing generator 20.
The inside of tower 30 is used for operational inspection and maintenance provided with vertical elevator 302.Eliminate the labor climbed under big height
It is tired, while improve routing inspection efficiency.
The top of tower 30 is provided with a horizontal positioned truss 303, and the both ends of truss 303 are stretched out in tower 30, this reality
Example is applied to wait place stretching, truss 303 is used for fixed block car.The wire rope hoist on truss 303, lifted and sent out using hoist engine
Motor 20 and vertical axis rotor 10, without other ground large crane.So the height of tower 30 is not just risen by ground
The constraint of the height of hoisting machinery.The rod member of truss 303 be connected by screw bolts (also for when installing lifting truss 303 not
Use large-scale ground crane in addition).Truss 303 and hoist engine located at the both ends of truss 303 together constitute tower 30 from
Lift-type crane, steel construction piece and the cast-in-place concrete of tower 30 are lifted when tower 30 is constructed.Exist in truss 303 and hoist engine
Generator 20 is no longer removed after installing, and is used in maintenance.
Also referring to Fig. 4 and Fig. 5, in the present embodiment, wind wheel rotating shaft 101 is cylindrical in shape and is rotatably arranged in the outer of tower 30
Wall, the inner side of wind wheel rotating shaft 101 is permanent-magnetic clamp.The stator 201 of generator 20 is additionally provided between the outer wall and permanent-magnetic clamp of tower 30,
There is air gap between stator 201 and permanent-magnetic clamp.
Above-mentioned, wind wheel rotating shaft 101 is cylindrical, and its inner side is permanent-magnetic clamp so that wind wheel rotating shaft 101 is when rotating as hair
Rotor 202 in motor 20, by the continuous rotation cutting magnetic induction line of rotor 202 so as to generate electricity, the generator 20 of the structure is
External permanent magnet direct-drive generator 20.
Stator 201 includes the iron core of stator 201 and the winding of stator 201 being wound on the iron core of stator 201, and stator 201 is unshakable in one's determination
It is sheathed in tower 30.Wind wheel rotating shaft 101 is in steel platform 301.The axial end of wind wheel rotating shaft 101 and steel platform 301 it
Between be provided with bearing, by setting bearing to reduce the frictional force between wind wheel rotating shaft 101 and steel platform 301.Wind wheel rotating shaft 101 simultaneously
Diametrically constrained between tower 30 by level to constraint bearing.
Also referring to Fig. 6, vertical axis rotor 10 includes support arm 102, wind oar rotating shaft 103 and wind oar 104.Support arm

In the present embodiment, a wind direction sensing device and a drive device 107 are equipped with each wind oar 104.Pass through
Wind direction sensing device judges the windward or leeward of wind oar 104 thereon, so as to feed back to drive device 107, drive device 107
Control wind oar 104 rotates.
Due to the presence of the angle of attack of wind oar 104, vertical axis rotor 10 could rotate, and the angle of attack is relative to one end circular motion
Outer tangent line angle, i.e., when wind direction is parallel with wind oar 104, the angle of attack is zero, and wind oar 104 does not stress, and the angle of attack is not in the case of remaining
It is zero, wind oar 104 or by thrust or by resistance.
Because the driving force that vertical axis rotor 10 rotates comes from the horizontal component of wind.Drive device 107 drives windward partly
The wind oar 104 in week divides to so that the driving force of half cycle is maximum windward perpendicular to the level of wind direction all the time.Drive device
The wind oar 104 of 107 driving contrary wind half cycles all the time parallel to wind direction level point to, though so that the resistance of contrary wind half cycle is not
Zero, but it is as small as possible, improve the utilization rate of wind energy.
Drive device 107 is motor, and the output shaft of motor is connected with wind oar rotating shaft 103.Vertical axis rotor 10 is at work
Rotating always, wind oar 104 also in continuous change in real time, the change of its angle be it is continuous, be not the change of step evolution
Change, thus noise is small at work, vibrations are small for vertical axis rotor 10, the work that can stablize.
It is appreciated that drive device 107 in addition to motor can be used to drive, can also use hydraulic-driven, connecting rod
Driving or the combination of the electronic connecting rod that surges driving.Motor drives wind oar rotating shaft 103 except that can be connected directly between wind oar rotating shaft 103
Beyond rotation, by drive link wind oar rotating shaft 103 can also be driven to rotate, the structure is relatively conventional to will not be described here.
Realize that small area is against the wind in different wind directions, improves the utilization rate of wind energy by 104 rotatable structure of wind oar.
And during vertical axis wind wheel rotates, wind oar 104 rotates in real time, turn to steady, continuous.
