The junction of blade, connecting rod and vertical axis is easily broken off, the normal production of influence, there is potential safety hazard.Up to reason luer blade energy
It is enough to solve the problem of connecting rod is broken well, it is existing up to reason luer blade by medial arc section and be separately positioned on it is described in
Between segmental arc top and bottom straight line linkage section composition, will portion and lower part on the vertical axis in the fixed luer blade up to reason
A fixed cover is not arranged, along the circumferential direction provided with the connecting plate being be arranged in parallel with corresponding straightway on fixed cover outer wall,
Connecting plate is connected by bolt with corresponding straight line linkage section.Although without connecting rod connection, having prevented blade and having connected with connecting rod
The phenomenon for connecing place's fracture occurs, and still, straight line linkage section is connected by connecting plate with vertical axis, and connecting plate is connected with fixed cover
Place, connecting plate and straight line linkage section junction still have the risk of fracture, in addition, being limited by blade material and moulding process
System, existing height and the outside diameter ratio of impeller up to reason luer blade can not be excessive, otherwise can cause that centrifugal force is big, blade
It is unstable, therefore the wind power of wind wheel has been limited, influence generating efficiency；And it is existing up to reason luer blade tip and bottom
Straightway needs to fix with vertical axis by connector, is influenceed by wind-force and centrifugal force, connector still easy fracture, it is impossible to reach
To the purpose of safe power generation.
Utility model content：
The purpose of this utility model is to provide the vertical axis wind turbine that a kind of stability is strong, wind power is high.
The utility model is implemented by following technical scheme：Vertical axis wind turbine, it includes being respectively sleeved at vertical
One mounting flange of d-axis upper and lower part；Between two mounting flanges, along radially uniform point of the mounting flange
It is furnished with 2-8 blade；The canned paragraph of each blade passes through the bolt through fixing threaded hole and the corresponding fixation
Orchid connection.
Further, the blade includes vertical section, linkage section and the canned paragraph, on the top and bottom of the vertical section
End is respectively equipped with one section of linkage section, and two sections of linkage sections are symmetrical on the center line of the vertical section；In every section of company
The top for connecing section stretches out provided with one section of canned paragraph, and two sections of canned paragraphs are vertically set relative to the vertical section
Put, the fixing threaded hole is uniformly provided with every section of canned paragraph.
Further, the angle α between the linkage section and the vertical section is 90-135 °.
Further, the vertical section, two sections of linkage sections and two sections of canned paragraphs are formed in one structure.
Further, each mounting flange includes about two spaced annular flange dishes；It is each described
Blade tip and the canned paragraph of bottom are respectively placed between two annular flange dishes of the correspondence mounting flange.
Advantage of the present utility model：Blade interlude is vertical section, can effectively reduce rotor diameter, reduces centrifugal force,
Strengthen the stability of wind wheel；Blade vertical section and the length of linkage section than adjusting range it is wide, the utility model can be effectively improved
The wind power of the vertical axis wind turbine；Can be by blade and vertical axis by the bolt through fixing threaded hole
Fixed flange is connected, quick and easy for installation, and bonding strength is high, and cost is low, can avoid because caused by centrifugal force is excessive
Ftracture junction, it is ensured that safe and stable generating.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is blade construction schematic diagram.
Vertical axis 1, mounting flange 2, annular flange dish 21, blade 3, canned paragraph 31, bolt 32, vertical section 33, linkage section
34th, fixing threaded hole 35.
Embodiment：
As shown in Figure 1 to Figure 3, the wind turbines rotor of vertical axis 1, it includes being respectively sleeved at the top of vertical axis 1 with
One mounting flange 2 in portion；Between two mounting flanges 2,4 blades 3 are distributed with along mounting flange 2 is radially uniform；Blade 3
Including vertical section 33, linkage section 34 and canned paragraph 31, one section of linkage section 34, two are respectively equipped with the top and bottom of vertical section 33
Section linkage section 34 and the entirety of vertical section 33 are C-shaped；Reason luer blade phase is reached with equal height and the original of equal wind wheel area
Than the interlude of blade 3 is vertical section 33, can effectively reduce the wind wheel of vertical axis wind turbine described in the utility model
Diameter, reduces centrifugal force, strengthens the stability of wind wheel；Angle α between linkage section 34 and vertical section 33 is 110 °, vertical section 33
