Abstract
The invention relates to a spine line blade lift wind rotor of a vertical axis wind engine, which comprises two circular cover plates and three vertical shafts and spine line blades, wherein, the circular cover plates are completely identical and are arranged symmetrically, the vertical shafts are arranged between the circular cover plates, and the spine line blades are arranged uniformly around the circular cover plates. In a wind field, when the wind rotor rotates around the axis of the wind rotor, the three spine line blades mutually serve as spoilers so as to change the direction of airflow and form a local airflow field which generates lift for one of the spine line blades. The lift generated for the spine line blade in the airflow field drives the wind rotor to rotate. The spine line blades are smoothly connected by a long arc plate and a short arc plate with reversed top arcs, and the three spine line blades are arranged uniformly around the circular cover plates. The wind rotor has the advantages of good appearance and high utilization ratio of wind energy.
Description
Technical field:
The invention belongs to the wind motor technical field, relate to a kind of fish crestal line impeller lift wind wheel of vertical-shaft wind motor.
Background technique:
Wind energy is a kind of cleaning, reproducible green energy resource, has become a kind of new energy that countries in the world competitively develop.Wind motor can be divided into horizontal shaft wind power engine and vertical-shaft wind motor.The wind wheel of vertical-shaft wind motor can be divided into lifting wind wheel and resistance type wind wheel, and application number is the three-halberd vortex-eliminating windwheel that 200810049517.4 Chinese invention patent application has been announced a kind of vertical-shaft wind motor.The structure of this wind wheel is to be that the cover plate of three halberd shapes encloses the three leaf closed cavity structures that form by three wind acanthus leafs 1 and bottom surface, top as shown in Figure 5, and the arcs top is towards the opposite and S shape circular arc plate level and smooth binding consists of by two sections for described wind acanthus leaf 1.Wherein be distributed with the air-flow slotted hole along short transverse on the outside arc plate of one section concave surface, make air-flow wind energy be acted on the impeller that does not have to facing the wind by three leaf closed cavities of this wind wheel, therefore this wind wheel is compared with traditional this wind wheel of Saab knob, the wind energy power efficiency is higher, but because being hole system institute on the impeller, air-flow cuts apart and the retardation of three leaf closed cavities of this wind wheel, so the mobile effect that can not to impeller produce lift of air-flow between impeller.So this wind wheel still is the resistance type wind wheel.Its performance is subjected to the limitation of resistance type wind wheel characteristic, and the power efficiency of wind energy improves limited, still can not with the wind energy power efficiency of a lifting wind wheel ratio mutually.
Summary of the invention:
The object of the present invention is to provide a kind of fish crestal line impeller lift wind wheel of vertical-shaft wind motor, compare with three-halberd vortex-eliminating windwheel, this wind wheel is converted into lifting wind wheel by the resistance type wind wheel, has higher wind energy power efficiency.
Technological scheme of the present invention is a kind of fish crestal line impeller lift wind wheel of vertical-shaft wind motor, be between two the circular shroudings and two circular shroudings of three vertical set whats by identical up and down correspondence, combine along the circumferential uniform fish crestal line impeller of circular shrouding.The curve that the bus of the neuter curved surface of described fish crestal line impeller consists of for the isometrical tangent circular arc of the long and short two section of likeness in form herringbone shape, the central angle of two sections circular arcs is respectively 84.5 ° and 36.5 °, and its radius of arc is wind wheel radius R * tg30 °; Described up and down circular shrouding is the Inlaid embedding locating notch of uniform three fish crestal line impeller along the circumferential direction, and the end points of 84.5 ° of arcs of its notch assurance fish crestal line is the wind wheel radius R apart from the distance of circular shrouding center line (being the wind wheel spin axis); The end points of 36.5 ° of arcs of assurance fish crestal line is wind wheel radius R * sin15 ° apart from the distance of circular shrouding center line (being the wind wheel spin axis).In wind field, this wind wheel is when the rotation of self axis, and three fish crestal line impeller are guide plate each other, the direction of air-flow is changed, thereby form the local gas flow field that one of them fish crestal line impeller is produced lift.So be called the fish crestal line impeller lift wind wheel of vertical-shaft wind motor.

Among the figure: 1. the circular shrouding center hole of the setting circle 2-3. of the little end of arc of concave surface 2. circular shrouding 2-1. fish crestal line impeller Inlaid embedding locating notch 2-2. fish crestal lines of the convex surface 1-3. fish crestal line impeller of bus (fish crestal line) the 1-2. fish crestal line impeller of fish crestal line impeller 1-1. fish crestal line impeller neuter curved surface
Embodiment
As shown in Figure 3, wind wheel of the present invention is combined with identical up and down circular shrouding 2 by three fish crestal line impeller 1.It is that three fish crestal line impeller 1 are installed in up and down among the fish crestal line impeller Inlaid embedding locating notch 2-1 on two circular backplates 2, along fish crestal line plate with the bonding crack sealing of backplate is fixed in aggregates up and down, namely become to make it around the fish crestal line impeller lift wind wheel of the vertical-shaft wind motor of its axis rotation.
This wind wheel is lifting wind wheel, the flow field streamline distribution rough schematic of this wind wheel as shown in Figure 4, the facing the wind convex side streamline density of fish crestal line impeller of among the figure is higher, and the streamline density of concave side is lower, the airspeed of this fish crestal line impeller convex side of namely flowing through is higher, and the airspeed of this fish crestal line impeller concave side of flowing through is lower, thereby shows when air-flow passes through wind wheel, to produce lift to this fish crestal line impeller, this lift becomes the wind opinion around the motive force of wind wheel axis rotation.The result of small-sized wind tunnel test shows that also such analysis is correct.
The sample of this test is three-halberd vortex-eliminating windwheel model and the vertical-shaft wind motor fish crestal line impeller lift wind wheel model of two formal parameters and the identical vertical-shaft wind motor of supporting structure, under identical test conditions, all speed ratios of vertical-shaft wind motor fish crestal line impeller lift wind wheel (being wind wheel impeller wing tip speed/wind speed) are greater than 1, and all speed ratios of vertical-shaft wind motor three-halberd vortex-eliminating windwheel only about 0.5.This is because the resistance type wind wheel can not produce the result that blade wing tip speed surpasses or equal wind speed, also is the lower reason of resistance type wind wheel wind energy power efficiency.This test result has verified that equally vertical-shaft wind motor fish crestal line impeller lift wind wheel is the analysis conclusion of lifting wind wheel.
This wind wheel is beautiful shape not only, and the wind energy power efficiency is also higher.
