Description
Technical field
This utility model is related to a kind of new vertical wind-driven generator.
Background technology
Existing wind-driven generator is nearly all the wind-driven generator of level, horizontal axis wind-driven generator, its fan blade system
Make complicated, during rotating a circle, by the comprehensive function of inertia force and gravity, the direction of inertia force is to change at any time to blade
, and the direction of gravity is constant all the time, suffered by such blade is exactly an alternate load, this fatigue strength right and wrong to blade
Chang Buli's.In addition the electromotor of trunnion axis is all placed in tens meters of high-altitude, and this brings to installation, maintenance and the maintenance of electromotor
A lot of inconvenience, stressing conditions in rotary course for the vertical shaft wind impeller blade are much better, due to the side of inertia force and gravity
Constant to remaining, suffered is permanent load, and therefore fatigue life is longer than horizontal axis rotor.Meanwhile, the big wind-force of vertical axises
Electromotor can be placed on the lower section of wind wheel, be easily installed and safeguard, and cost of manufacture is also little.But present vertical wind power generation
, due to the area constraints by leaf blade, power is all smaller for machine.Existing vertical-type wind-driven generator is mostly several hectowatts
To several kilowatts of small generator.Wind energy cannot be made full use of, and equipment just calculates unit power cost greatly.
Utility model content
The purpose of this utility model is to disclose a kind of new vertical wind-driven generator, after fan blade set, is somewhat like BAIYE
Window, can increase wind area, thus increasing generated output.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of new vertical wind-driven generator, bag
Include fan blade main shaft, fan blade crossbeam, fan blade assembly, magnetic bearing, base and electromotor, if described fan blade assembly is by dry tablet wind
Leaf forms, and all fan blades pass through screw connection on fan blade crossbeam, and specifically Luo is connected on all wind on a fan blade crossbeam
Leaf forms a fan blade assembly, and described fan blade beam welding on described fan blade main shaft, pass through by the lower end of described fan blade main shaft
On magnetic bearing, the lower section of described magnetic bearing sets base to screw connection, and the other end of described base connects generator main
Axle, described fan blade main shaft is connect with the main shaft Luo of described electromotor.Magnetic bearing is to be processed with permanent magnetic iron, and it passes through to repel
Supporting the weight of blower fan, the benefit of magnetic bearing is not contact to power, does not thus have frictional force, between fan blade main shaft and base
It is supported using magnetic bearing, such blower fan rotation can reduce frictional force.The power of electromotor can also be increased.
Preferably, described fan blade main shaft includes some sections of steel plates and is welded, and welded flange on steel plate, between steel plate
Using screw connection.
Preferably, described fan blade crossbeam adopts T-steel or steel alloy or other composites.
Preferably, described fan blade is streamlined triangular groove fan blade or other shapes fan blade, and centre is closed by hinge
Live.
Preferably, described fan blade adopts aluminium sheet punch forming or other composites.
Fan blade rely on wind-force can natural folding, open increase front face area when windward, close when leeward, reduce lee face
Long-pending.Multi-disc leaf blade is combined into a fan blade assembly, and all fan blade assemblys are connected on fan blade crossbeam, all fan blades
Beam welding or screw are linked on fan blade main shaft, and all fan blade assemblys form a front face area.Thus greatly increasing
Plus front face area, leeward area minimizing.
This utility model adopts above-mentioned corrective measure, has the advantage that：This utility model vertical wind power generator is exactly
Increase fan blade area, and fan blade is by assembling, is somewhat like shutter, many blades are combined into a fan, then by multigroup wind
Leaf assembly constitutes a front face area.Wind area so can be made to increase by tens times to thousands of times；And each fan blade energy
Enough foldings, rely on wind-force naturally to open certain distance, increase front face area, and when leeward, be also to rely on wind-force certainly when windward
So closure certain distance, thus reduce leeward area.Thus greatly can utilize wind energy, so that vertical axis wind power generation
The power of machine increases.This utility model vertical wind power generator can make high-power generator（Tens kilowatts are arrived MW class）,
And generating set is arranged on ground, is so easily installed and safeguards, unit power cost is just little.
