In wind energy conversion system rotating shaft, one end of some lift-type blade support framves is fixed in support frame mounting disc, some described
Lift-type blade vertical direction arrangement, the center of each lift-type blade and the other end of corresponding lift-type blade support frame
It is fixedly connected, the pre- angle setting of lift-type blade is 0 °；To ensure stability and rigidity during the rotation of lift-type blade, three are utilized
Stayed structure is installed on angular stability principle, vertical axis windmill；The resistance-type blade mounting disc is arranged on wind energy conversion system
In rotating shaft, the resistance-type blade is arranged in resistance-type blade mounting disc, solves asking for vertical axis windmill startability difference
Topic.
The stayed structure includes suspension cable and jump stay；Between the top of adjacent lift-type blade and bottom
Between, it is connected with each other, between the two ends of lift-type blade and support frame mounting disc, is connected by suspension cable by jump stay
Connect.
The resistance-type blade not only increases the power of wind energy conversion system using oval blade using oval blade, and
And blade material is saved, reduce cost；Resistance-type blade is arranged on the lower section of lift-type blade, and two kinds of blades are mutually wrong
Open, it is to avoid influence each other its aerodynamic quality, so as to solve combined wind energy conversion system because blade combination causes power drop
Problem；And two blades of resistance-type blade laterally and longitudinally have gap, such a installation form can greatly improve vertical shaft wind
The startability and power of power machine.
The present invention compared with prior art, substantive distinguishing features and remarkable advantage is obviously protruded with following：
1. blade of vertical axis wind turbine will bear huge Wind impact under high wind speed, traditional vertical axis windmill is not
There is corresponding reinforced structure.The present invention adds the reliability of blade installation using the structure of drag-line, it is ensured that blade revolves at a high speed
Stability and rigidity under turning.
2. the startability of vertical axis windmill at low wind speeds is poor, traditional vertical axis windmill does not have accordingly
Measure.The form that the present invention is combined using lift-type blade with resistance-type blade, improves the startability of vertical axis windmill
Energy；Ellipse blade is further provided on the basis of combined blade and new blade installation form, not only increased
The startability and power of vertical axis windmill, and save blade material, reduces cost, with economy very high economy
Property.
The present invention effect be：
Inventive structure rationally, save material, the wind field environment under different wind speed be suitably applied, while not influenceing by practical function
The power and aerodynamic quality of vertical wind machine；Vertical shaft wind motor, which can effectively strengthen under blade high wind speed, bears wind
The ability of power impact, improves the startability of vertical-shaft wind at low wind speeds.

Embodiment
Accompanying drawing show vertical axis windmill according to an embodiment of the invention, below with reference to accompanying drawing in detail
Bright technical scheme.
As shown in Fig. 1 to 3, a kind of vertical axis windmill, including wind energy conversion system rotating shaft 1, lift-type blade 2, support frame installation
Disk 3, lift-type blade support frame 4, resistance-type blade mounting disc 7, resistance-type blade 8, base 9；The wind energy conversion system rotating shaft 1 is installed
On base 9, support frame as described above mounting disc 3 is arranged in wind energy conversion system rotating shaft 1, and one end of three lift-type blade support framves 4 is consolidated
It is scheduled in support frame mounting disc 3, three vertical direction of lift-type blade 2 arrangements, the center of each lift-type blade 2 and phase
The other end of corresponding lift-type blade support frame 4 is fixedly connected, and the pre- angle setting of the lift-type blade 2 is 0 °；To ensure lift
Stability and rigidity when type blade 2 rotates, using triangle stability principle, are provided with drag-line knot on vertical axis windmill
Structure；The resistance-type blade mounting disc 7 is arranged in wind energy conversion system rotating shaft 1, and the resistance-type blade 8 is pacified installed in resistance-type blade
In sabot 7, the problem of vertical axis windmill startability is poor is solved.
As shown in Fig. 2 the stayed structure includes suspension cable 5 and jump stay 6；On the top of adjacent lift-type blade 2
Between end and between bottom, be connected with each other by jump stay 6, the two ends of lift-type blade 2 and support frame mounting disc 3 it
Between, connected by suspension cable 5.
As shown in figure 3, the resistance-type blade 8 not only increases wind-force using oval blade using oval blade
The power of machine, and blade material is saved, reduce cost；Resistance-type blade 8 is arranged on the lower section of lift-type blade 2, two
Plant blade mutually to stagger, it is to avoid influence each other its aerodynamic quality, so as to solve combined wind energy conversion system because blade combination is led
The problem of causing power drop；And two blades of resistance-type blade 8 laterally and longitudinally have gap, and such a installation form can be significantly
Improve the startability and power of vertical axis windmill.
When arrives stream wind speed it is relatively low by vertical axis windmill when, resistance-type blade 8 due to its superior startability at first
Start, drive wind energy conversion system rotating shaft 1 to rotate, so as to drive lift-type blade 2 to start rotation, it is ensured that vertical axis windmill is in wind speed
Acting is remained in the case of relatively low.When wind speed is larger, impact of the external wind to lift-type blade 2 increases, now suspension cable 5
Played a role with jump stay 6, it is ensured that stability and rigidity of the lift-type blade 2 in the case where high speed rotates, improve vertical shaft wind
Reliability of the power machine under high wind speed operating mode.
