Description

The novel vertical-axis wind wheel

Technical field

The utility model relates to the wind energy conversion system technology, particularly a kind of novel vertical-axis wind wheel.

Background technique

Wind energy is a kind of inexhaustible clear energy sources, and people have deep love for it, designs the countless versions wind generating unit, and this device mainly is made of wind wheel and generator.The title horizontal axis rotor that the axle horizontal of wind wheel is installed, the vertically arranged title vertical axis rotor of axle of wind wheel.Compare with horizontal wind axis wheel electricity generating device, the advantage of vertical axis rotor electricity generating device is: because do not need to aim at wind direction mechanism, do not need support tower, gear and generator are installed in ground, thus cost low, be convenient to maintenance.As Fig. 1 is the schematic top plan view of existing vertical axis rotor, existing vertical axis rotor is made of main shaft 1, wheel hub 2, link stopper 3, rotating shaft 4, flabellum 5, link stopper 3 is fixing with wheel hub 2, the two ends (not shown) of rotating shaft 4 is also fixing with wheel hub 2, flabellum 5 is connected by bearing (not shown) and rotating shaft 4, and flabellum 5 can 4 turn over an angular displacement around the shaft.False wind is to shown in arrow among the figure, flabellum 5 countershafts 4 following and the right produce counter-clockwise torque, the flabellum 5 of top down the wind, the clockwise torque that countershaft 4 produces is minimum, it is also less that flabellum 5 countershafts 4 on the left side produce clockwise torque, thereby the resultant torque of all flabellum 5 countershafts 4 makes whole wind wheel counterclockwise rotation moving.In the continuous rotation process of vertical axis rotor, flabellum 5 is done reciprocal angular displacement campaign, at the end points bump link stopper 3 of angular displacement and the cylindrical or the cushion block on the cylindrical (if cushion block is set on cylindrical) of wheel hub 2, infringement flabellum 5, have a strong impact on its life-span, and association vibration, noise.This is existing vertical axis rotor obvious defects.

Summary of the invention

The utility model designs a kind of novel vertical-axis wind wheel, and purpose is to overcome the above-mentioned defective of existing vertical axis rotor, prolongs the life-span of vertical axis rotor, improves its wind-power electricity generation efficient.

The utility model is realized by following technological scheme.

Show as Fig. 2 to Fig. 5.Non magnetic wheel hub 11 and main shaft 6 coaxial assemblings; The cylindrical of the outer ring of bearing 7 and non magnetic wheel hub 11 is fixed, the inner ring assembling of rotating shaft 8 and bearing 7, and rotating shaft 8 and bearing 7 are evenly arranged some groups along the cylindrical of non magnetic wheel hub 11, have drawn four groups among the figure and have only illustrated; In rotating shaft 8, connect flabellum 13, flabellum 13 usefulness nonmagnetic substances are made, and it is adorning the cuboid shape permanent magnet 12 that magnetizes along thick direction near the inner chamber that there is a cuboid at rotating shaft 8 places, the cross direction of permanent magnet 12 is consistent with the cross direction of flabellum 13, and length direction is consistent with the axis direction of rotating shaft 8; Near rotating shaft 8 block 18 is set evenly at two up and down of non magnetic wheel hub 11 cylindrical, block 18 is by wedge shape magnetic inductive block 14, cuboid permanent magnetic plate 15, non magnetic lath 16, wedge shape magnetic inductive block 17 fixed compositions, one straight flange of wedge shape magnetic inductive block 17 is parallel to the line of centers of rotating shaft 8 and main shaft 6, this straight flange of wedge shape magnetic inductive block 17 is more bigger than the radius of flabellum 13 root semicircles to the distance at rotating shaft 8 centers, cuboid permanent magnetic plate 15 promptly magnetizes with the tangential parallel direction of the cylindrical of non magnetic wheel hub 11 along thick direction, and require to forward its cross direction to when parallel with the line of centers of main shaft 6 with rotating shaft 8 when flabellum 13, cuboid permanent magnetic plate 15 is relative with permanent magnet 12 like poles, and the hypotenuse of wedge shape magnetic inductive block 14 is tangential along non magnetic wheel hub 11 cylindricals; The fixed non magnetic clamping plate 9 and 10 in the upper and lower end face of block 18, non magnetic clamping plate 9 are identical with block 18 with 10 shape, the coincidence of aliging vertically of non magnetic clamping plate 9 and 10 end face and the end face of block 18.

False wind is to being among the figure shown in the arrow, flabellum 13 countershafts 8 following and the right produce counter-clockwise torque, the flabellum 13 of top down the wind, the clockwise torque that countershaft 8 produces is minimum, it is also less that flabellum 13 countershafts on the left side produce clockwise torque, thereby the resultant torque of all flabellum 13 countershafts 8 makes whole wind wheel counterclockwise rotation moving.Different with existing vertical axis rotor is that when flabellum 13 forwarded near block 18, because the effect of magnetic repulsion, flabellum 13 can not clash into block 18.

The effect that the utility model is useful is:

When 1, working, flabellum 13 can not clash into block 18, thereby has avoided flabellum 13 and block 18 to injure mutually, has avoided bump vibration, noise, has prolonged the life-span of wind wheel greatly;

2, the inevitable off-energy of mechanical impact has been avoided bump also just to significantly reduce energy loss, thereby has been improved efficient, and the utility model is achieved many things at one stroke thus.
