Explain a kind of opposite rotary vertical shaft type wind-mill generator control that the present invention is provided in detail below in conjunction with accompanying drawing System.
With reference to Fig. 1, a kind of opposite vertical-axis wind driven generator device includes permanent magnet machines 3, and the permanent magnet machines 3 include the He of stator 30 Outer rotor 31.The stator 30 is in cylinder, and the outer rotor 31 is then cylindrical, and the inside radius of outer rotor 31 is more than institute The radius of stator 30 is stated, so that stator 30 can be at the inner hollow position of outer rotor 31 relative to freely rotating, the stator 30 and outer rotor 31 can rotate, its title is the title using conventional art, it is impossible to limit its function.
This opposite rotary vertical shaft type wind-mill generator control system also includes stator vane group 1 and outer rotor blade group 2.The stator vane group 1 is arranged on stator 30, and can drive the stator 30 in a first direction(For example clockwise) Upper rotation;And outer rotor blade group 2 then be arranged on outer rotor 31 on, and can drive the outer rotor 31 with the first direction Opposite direction(For example counterclockwise)Upper rotation.That is, stator 30 and outer rotor 31 drive in respective blade group Lower opposite direction rotating, compared with the wind-force machine that only one of which outer rotor in the prior art rotates, the technology makes turning for permanent magnet machines Speed is doubled.
In the present embodiment, the stator vane group 1 and outer rotor blade group 2 all include a plurality of(The present embodiment is 3 It is individual)Blade in blade, stator vane group 1 we term it stator vane 10, and blade in outer rotor blade group 2 we claim Be outer rotor blade 20, no matter structure or function are just as the stator vane 10 and outer rotor blade 20, thus under If only introducing one of which blade in text, another blade is also same 26S Proteasome Structure and Function, is not just described still further.
In the present embodiment, the stator vane group 1 and outer rotor blade group 2 all include a plurality of(The present embodiment is 6 It is individual)The connection blade connected in blade, stator vane group 1 connects blade 11 we term it stator, and in outer rotor blade group 2 Connection blade connect blade 21 we term it outer rotor, no matter are stator connection blade 11 and outer rotor connection blade 21 What structure or function were just as, if therefore hereinafter only introduce one of which connection blade, another connection blade It is same 26S Proteasome Structure and Function, does not just describe still further.
Whether stator vane group 1 or outer rotor blade group 2, are all to be connected to stator 30 by respective connection blade Or on outer rotor 31.
This opposite rotary vertical shaft type wind-mill generator control system also includes the support permanent magnet machines 3 and described The pylon 4 of stator vane group 1 and outer rotor blade group 2.The pylon one end connects the permanent magnet machines 3, and the other end is then embedded to ground It is lower to be used to fix the wind-force machine.
With reference to Fig. 2, the Fig. 2 is the profile of permanent magnet machines 3.The permanent magnet machines 3 include stator 30 and outer rotor 31.It is described The top of stator 30 is provided with stator flange disk 300, and the stator flange disk 300 is used to install stator connection blade 11 so as to fixed Stator vane 10.The top of the outer rotor 31 is provided with outer rotor ring flange 310, and the outer rotor ring flange 310 is used to install Outer rotor connection blade 21 is so as to fixed outer rotor blade 20.The outer rotor 31 also includes a support tube 312, in the support tube 312 top is equipped with bearing 301, and the bearing 301 can be ball bearing or the bearing of other supports and lubrication, bearing 301 contribute to stator 30 swimmingly to be rotated relative to support tube 312.In support tube 312 and the rotating part of outer rotor 31(Figure is not Show)Between bearing 311 is housed, in the present embodiment, the bearing 311 includes 4 discrete bearings, and having 3 discrete bearings to be located at should The upper end of support tube 312, has 1 discrete bearing to be located at the lower end of the support tube 312.The lower end of support tube 312 is fixed on institute State on pylon 4(It is not shown), consequently, it is possible to stator 30 can rotate relative to support tube 312, the rotating part of outer rotor 31 Rotated relative to support tube 312, as long as just may decide that stator 30 and outer rotor 31 by the different installation directions of blade group Direction of rotation.
With reference to Fig. 3, a kind of stator for opposite rotary vertical shaft type wind-mill generator control system that Fig. 3 provides for the present invention The structure chart of blade.Because the structure and mode of operation of outer rotor blade and stator vane are just the same, therefore only describe here Stator vane, outer rotor blade is not just described still further.As illustrated, stator vane 10 includes main wing 100 and wing flap 101, should Wing flap 101 is provided with gear train 102 close to one end of main wing 100, and the gear train 102 passes through a power transmission shaft(It is not shown)By one Its operating of the control of direct current generator 103, the direct current generator 103 is by a wireless remote controller(It is not shown)Control it to operate, and then control Gear train 102 processed is operated, and gear train 102 will drive the wing flap 101 to adjust drift angle relative to main wing 100.
The wind-force machine can start under breeze conditions, during breeze start-up, and it is described fixed to be controlled by wireless remote controller Partially, referring to Fig. 5, when inclined under wing flap 101, stator vane 10 will obtain larger startup torque to the wing flap 101 times of blades 10, Can smoothly it start under breeze conditions.When start completion, wind speed is also in specified scope, i.e., the wind-force machine is operated in When under normal condition, the wing flap 101 of the stator vane 10 and the no drift angle of main wing 100, ginseng are controlled by wireless remote controller See Fig. 4, i.e., the wing flap 101 keeps streamlined contour with main wing 100, and the profile meets aerodynamic characteristics requirement.When wind speed mistake It is big when needing to reduce the rotating speed of blade group, by wireless remote controller control on the wing flap 101 of the stator vane 10 partially, referring to Fig. 6, now the pneumatic torque of stator vane 10 reduces, and then reduces the rotating speed of stator vane group 1.The control device of wireless , because the technology is known technology, it can will not be repeated here using single-chip microcomputer as controller.
In one particular embodiment of the present invention, each stator vane 10 and each outer rotor blade 20 are adopted With NACA2414 or NACA23012 aerofoil profiles, there is support keel packing using centre, the structure shape of glass fibre is wrapped in outside Formula, to mitigate weight and make appearance profile ensure certain shape, strength and stiffness.
In one particular embodiment of the present invention, stator connection blade 11 and the outer rotor connection blade 21 is Lift aerofoil profile connects blade, and the lift produced using air force reduces bearing load during rotation, improves bearing and uses the longevity Life.
Above disclosed is only the preferred embodiments of the present invention, can not limit the right of the present invention with this certainly Scope, therefore the equivalent variations made according to scope of the present invention patent, still belong to the scope that the present invention is covered.
