Without trunk rotation plate type vertical axis windmill

Technical field

The utility model relates to vertical axis windmill, particularly without trunk rotation plate type vertical axis windmill.

Background technique

Horizontal shaft wind-power generating system is world today's wind-power electricity generation mainstream model, technology maturation, and lots of production is large.But the shortcoming of horizontal shaft wind-power generating system is day by day remarkable, it starts, and wind speed is high, operating noise is large, wind loading rating is poor, must be to wind, use driftage gyroscopic drive system, must use gear ratio up to 100 above speed-changing gear boxs, be difficult to realize wind energy conversion system generator is directly driven.Tower cylinder or pylon height that MW class wind-force is sent out system are many at 70～80M, blade circular diameter is up to 135M, length of blade 65M, the wind-force of driftage pivoting support institute load-bearing is sent out system equipment gross weight up to more than 100 tons, and this series data shows: horizontal shaft wind-power generating system has developed into historical top stage.

From at the beginning of Wind Power Development till now, people place hope on vertical axis wind power generation system always, good its starts feature that wind speed is low, aerodynamic noise is little, wind-engaging performance is good for a long time.It is exactly vertical axis windmill that China utilizes the form of wind energy the earliest.Yet than horizontal shaft wind-power generating system, vertical axis wind power generation system does not obtain due development, big the making us of gap sighed with feeling.Vertical axis wind power generation system slower development, no doubt has the reason of the aspects such as investment, and still, main cause is still at technical elements, and the root of problem is just being hidden in the habitual things of people.

For the understanding of the Vertical direction axle of vertical axis wind power generation system, should be understood that the concept of difference main shaft and trunk, and be consistent with the main shaft concept definition of horizontal shaft wind-power generating system.Main shaft refers to from experiencing blade movement and rotates, and the line shaft that drives generator amature to rotate; Trunk refers to and self do not rotate, only the positioning support strut around, support as the blade rotating and support institute thereof.

Horizontal shaft wind-power generating system does not have trunk, and main shaft is very short, and large-scale wind electricity system only has 6～8M.Although the trunk of vertical axis wind power generation system is very high, as famous Da Lie bifolium wind energy conversion system, (the engineer Da Lie Darrieus1931 of Air France Group has invented lift vertical shaft wind energy conversion system.), there is 34M high, very grand.On Da Lie wind energy conversion system trunk, overlap a bracket tube or 2 support rings, bracket tube or support ring, around trunk, rotate with fan blade.The effective length of the main shaft of Da Lie bifolium wind energy conversion system should be from the bottom of the bracket tube that rotates or support ring to the head end of generator amature mechanism (no matter being internal rotor or external rotor), its effective length is in fact similar with the main axis length of horizontal shaft wind-power generating system, also only has 6～8M.Traditional and existing vertical axis windmill, comprise classical Φ type, and the significant structure of the H type wind energy conversion system that gets up of latest developments is: have trunk, blade and support rotate around trunk.People are accustomed to the typical structure of vertical axis windmill, the unmanned query trunk of this wind energy conversion system and the function of supporting structure.

The classical major defect with existing vertical axis windmill is:

The torque of vertical axis windmill is directly proportional to the product of blade rotary circle radius and blade average vertical length.The blade rotary circular diameter of Φ type or H type vertical axis windmill and blade average vertical length originally should be uncorrelated with height and the intensity of trunk.But, because blade and support thereof rotate around trunk, rely on trunk to support, therefore, trunk is top dog in structure.The height of trunk and intensity must restrict the increase of blade rotary circular diameter and blade vertical length, and blade rotary circular diameter and blade vertical length itself have been lost the independent attribute of autonomous change.

Classics with existing vertical axis windmill in, increase torque, can not directly strengthen blade rotary circular diameter and blade average vertical length, and must first expand and strengthen support, then could increase blade circular diameter and blade vertical length (circular arc vane can represent its average vertical length by its diameter or chord length).Blade circular diameter determines by the radial dimension of support completely, and blade average vertical length also depends on size and the intensity of place support.Conventionally be difficult to separately support be carried out to aerodynamic design, the suffered resistance of support is directly proportional to its weight and size.

In classical and existing vertical axis windmill, blade and support thereof are that external rotor rotates around the rotation of trunk.Rotating what match with external rotor is outer rotor generator, and wants drive shaft generator, just must increase transmission switching mechanism.The H type vertical axis windmill that latest developments are got up is mostly used low-power external rotor permanent magnet generator, though this small-power power generation system can be used for lighting street lamp, and can not be for commercial electricity production.The wind energy conversion system structure of external rotor is unfavorable for driving powerful rotating shaft generator.

In classical and existing vertical axis windmill, blade and support thereof rotate around trunk, this structure is unfavorable for introducing power supply on support and blade, the angle of revolution (attack angle regulator for vane of existing vertical axis windmill is all machinery type) that cannot use motor adjusting vane on the support rotating or blade; Cannot access lubricant pipe, cannot be the floating bearing automatic filling lubricant oil on blade or support with electric oil pump.
