Technical field
The invention belongs to technical field of wind power generation, be specifically related to a kind of vertical axis wind power generation impeller with moving vane.
Background technique
The energy is power and the guarantee of human social development progress.In recent years, along with the high speed development of global economy, coal, oil, the conventional energy resources such as rock gas are by fast, and a large amount of consumption, this allows the mankind not only in the face of the increasingly exhausted pressure of resource, receives the threat that environment constantly worsens simultaneously.The energy and environmental protection have become the pressing problem that mankind nowadays survival and development are badly in need of solving.Wind-powered electricity generation is as a kind of new energy of clean environment firendly, neither consume limited coal resources, also valuable underground wind-resources can not be consumed, more be conducive to the sustainable development of national economy, district greatly develops the wind power plant of the high efficient and reliable of applicable concrete area feature is throughout the country coming.Realize the industrialization of wind-power electricity generation, practical, require dynamical Fan Product, can utilize wind energy to greatest extent, this just requires that we study the performance of wind energy conversion system, improves blower fan and catches the maximum of wind energy, produces efficient energy and transforms.
At present, the principal mode of wind-power electricity generation is electric energy by blower fan apparatus by wind energy transformation, therefore design a kind of efficient, reliably blower fan be the key technology of Wind Power Utilization.The moulding of blower fan should consider that structure also will consider the other factorses such as weight.Current blower fan form mainly contains horizontal axis blower fan and vertical shaft fan two kinds, that impeller axis is parallel with the relative position of wind direction is horizontal axial type impeller (HAWT), and that impeller axis is vertical with the relative position of wind direction is perpendicular axis type impeller (VAWT).
Same level axle Wind turbines is compared, and vertical axis wind electric unit has following advantage:
(1) perpendicular axis type impeller axis is with to carry out flow path direction vertical, can catch the wind energy in any direction, and structure is simple, is well suited for miniaturization Independent Power Generation.
(2) vertical shaft fan installation and maintenance is simple, and manufacturing process is simple, and cost is low, and Economy is strong.
(3) vertical shaft fan to blade structure and requirement of strength low.
(4) perpendicular axis type impeller can be effectively worked at complicated turbulent flow, is therefore more suitable for the small-size wind power-generating place being applied in complex-terrain, as the rural area of remote districts.
(5) tip-speed ratio horizontal axis impeller little of vertical axis impeller blade, under such slow-speed of revolution, aerodynamic noise is very little, even can reach quiet effect, be conducive to environmental protection.
Vertical axis impeller common at present mainly contains lift vertical shaft impeller and resistance-type vertical axis impeller.The main representative of lift-type is Darrieus impeller, and the main representative of resistance type is Savonius impeller.
Be in the innovation and creation of US1835018 A at publication number, disclose a kind of Darrieus wind-force impeller.This blade wheel structure is simple, lift coefficient is high, but startability is poor, is difficult to especially at low wind speeds start.
Be in the innovation and creation of US1766765 A at publication number, disclose a kind of Savonius wind-force impeller.This impeller startability is good, has very large wind speed and utilizes scope, but along with the rotation of rotor, its torque amplitude of variation is from high to low very large, even can drop to the degree close to zero, therefore have lower total efficiency.

Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
As shown in Figure 1, a kind of vertical shaft wind power impeller, forms primarily of main shaft 4, upper bracket 2, lower support frame 8, first baffle plate 3, second baffle 5, third gear plate 9, fourth gear plate 11, first blade 1, second blade 6, Three-blade 7, quaterfoil 12 and mobile base 10.
As shown in Figure 2, main shaft 4 is cylindric, respectively has a boss in the position of spindle top and bottom, is respectively the first boss 13, second boss 14.Main shaft 4 is arranged in mobile base 10.
First boss 13 and the second boss 14 are cylindric, both equal diameters.The axis of the first boss 13 and the axis of the second boss 14 all with the dead in line of main shaft 4.First boss 13 is positioned at the top of main shaft 4, and the second boss 14 is positioned at the bottom of main shaft 4.
As shown in Figure 3, upper bracket 2 is cross bracket.There is a main shaft fixed hole 15 centre of upper bracket 2, and its diameter is slightly larger than the diameter of main shaft.Four external part ends of upper bracket respectively have a blade fixed hole, and be followed successively by the first blade fixed hole 16, second blade fixed hole 17, Three-blade fixed hole 18 and quaterfoil fixed hole 19, its diameter is slightly larger than the diameter of sharf.
Lower support frame 8 is identical with the structure of upper bracket 2.
First baffle plate 3, second baffle 5, third gear plate 9 are identical with the structure of fourth gear plate 11, as shown in Figure 4, are narrow cuboid.Baffle length is equal to the distance on main shaft 4 between first boss 13 and the second boss 14.
First blade 1, second blade 6, Three-blade 7 are identical with the structure of quaterfoil 12, as shown in Figure 5, are rectangle.Axle 20 on a blade is stretched out in the top of blade right hand edge, and a blade lower shaft 21 is stretched out in below, the dead in line of diaxon, and diameter is identical, is all slightly less than the diameter of blade fixed hole.Blade is fixed in the blade fixed hole of upper bracket 2 and lower support frame 8, and the axis of axle 20 and blade lower shaft 21 rotates on blade.
As shown in Figure 6, impeller rotates under the action of the forces of the wind along clockwise direction.
Turn in the process of B point at the first blade 1 by A point, when the first blade 1 does not forward substantially horizontal to, by wind effect, the first blade 1 is parallel with wind-force direction with quaterfoil 12, does not produce moment against the wind; Second blade 6 is close on second baffle 5, and Three-blade 7 is close on third gear plate 9, produces moment with the wind.
When the first blade 1 forwards substantially horizontal to, first blade 1 starts to be close on the first baffle plate 3, now, quaterfoil 12 is still parallel with wind-force direction, second blade 6 is still close on second baffle 5, but blade Three-blade 7 is left from third gear plate 9, turn over 180 degree clockwise, parallel with wind-force direction.
When the first blade 1 is rotated further the process of B point from substantially horizontal, the first blade 1 and the second blade 6 are close on the first baffle plate 3 and second baffle 5 respectively, produce moment with the wind; Three-blade 7 and quaterfoil 12 and wind direction keeping parallelism, do not produce moment against the wind.
When the first blade 1 arrives B point position, quaterfoil 12 forwards the position of original first blade 1 to, restarts the rotation process of above-mentioned first blade 1.
