Abstract
The invention discloses a blade of a wind driven generator. The blade comprises a blade body which is composed of two blade plates, an upper cross bar, a lower cross bar and a rotating shaft. The centers of the upper cross bar and the lower cross bar are fixed on the rotating shaft, the two blade plates are movably mounted at two ends of the upper cross bar respectively and located on the same side along the axial direction of the upper cross bar, one end of the lower cross bar and the upper cross bar are located on the same side of each blade plate, and the other end of the lower cross bar is located on the other side opposite to one side, on which the upper cross bar is located , of each blade plate. The blade is simple in structure, free of a turning system, capable of utilizing wind energy by 360 degrees and high in wind energy utilization rate.
Description
Technical field
The invention belongs to wind power generation field, particularly a kind of power-driven generator leaf.
Background technique
Fan blade is the critical component of wind-driven generator, and common power-driven generator leaf is propeller formula at present.Adopt the general direction windward of propeller type fan blade to fix, and in most cases, wind vector is frequent, such wind-driven generator wind energy utilization is low, and fan blade shape designs, manufacture is complicated, and processing cost is high.Some wind-driven generators improve wind energy utilization by being provided with empennage steering system, and the wind-driven generator build of this class is huge, has increased processing cost, manufacture complicated.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, without steering system, can 360 degree utilize wind energy, and the high power-driven generator leaf of wind energy utilization.
The technical solution that realizes the object of the invention is:
A power-driven generator leaf, comprises fan blade body, and described fan blade body is comprised of impeller, upper cross bar, lower cross bar and rotating shaft; Wherein, described upper cross bar and lower cross bar center are separately fixed in rotating shaft, two impeller are movably arranged on respectively upper cross bar two ends, and be positioned at along the same side of upper cross bar direction, the coexist one side of impeller of lower cross bar one end and upper cross bar, the lower cross bar the other end is positioned at the another side of upper cross bar place impeller one side.
The present invention compared with prior art, its remarkable advantage:
A kind of blade structure for wind driven generator of the present invention is simple, is easy to manufacture, and cost is low, and 360 degree utilize wind energy, and without steering system, and wind energy utilization is high.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is working effect schematic diagram of the present invention.
Embodiment
As shown in Figure 1: a kind of power-driven generator leaf of the present invention, comprise fan blade body, described fan blade body is comprised of impeller 1, upper cross bar 3, lower cross bar 4 and rotating shaft 5; Wherein, described upper cross bar 3 and lower cross bar 4 centers are separately fixed in rotating shaft 5, two impeller 1 are movably arranged on respectively upper cross bar 3 two ends, and be positioned at along the same side of upper cross bar 3 directions, the coexist one side of impeller 1 of lower cross bar 4 one end and upper cross bar 3, lower cross bar 4 the other ends are positioned at the another side of upper cross bar 3 place impeller 1 one sides.Impeller 1 is enclosed within on upper cross bar 3 by external member 6, and upper cross bar 3 two ends are provided with bounding means 2.Upper cross bar 3 is positioned at upper half part of impeller 1.Rotating shaft 5 is provided with 1 or 1 above fan blade body.
Embodiment 1:
A power-driven generator leaf, comprises fan blade body, and described fan blade body is comprised of impeller 1, upper cross bar 3, lower cross bar 4 and rotating shaft 5; Wherein, two described impeller 1 are enclosed within on upper cross bar 3 by hollow cylinder 6 respectively, and be positioned at the axial the same side of upper cross bar 3, upper cross bar 3 and lower cross bar 4 centers are weldingly fixed on respectively in rotating shaft 5, the coexist one side of impeller 1 of lower cross bar 4 one end and upper cross bar 3, lower cross bar 4 the other ends are positioned at the another side of upper cross bar 3 place impeller 1 one sides; Described upper cross bar 3 two ends are provided with the bounding means 2 of boss structure, and upper cross bar 3 is positioned at upper half part of impeller 1, and rotating shaft 5 is provided with 1 fan blade body.
Embodiment 2:
A power-driven generator leaf, comprises fan blade body, and described fan blade body is comprised of impeller 1, upper cross bar 3, lower cross bar 4 and rotating shaft 5; Wherein, two described impeller 1 are enclosed within on upper cross bar 3 by annulus 6 respectively, and be positioned at the axial the same side of upper cross bar 3, upper cross bar 3 and lower cross bar 4 centers are spirally connected respectively and are fixed in rotating shaft 5, the coexist one side of impeller 1 of lower cross bar 4 one end and upper cross bar 3, lower cross bar 4 the other ends are positioned at the another side of upper cross bar 3 place impeller 1 one sides; Described upper cross bar 3 two ends are provided with the bounding means 2 of notch, and upper cross bar 3 is positioned at upper half part of impeller 1, and rotating shaft 5 is provided with 2 fan blade bodies.
Working principle:
As shown in Figure 2: a kind of power-driven generator leaf of the present invention, on same windward side, be positioned at two impeller 1 on rotating shaft 5 both sides, secund impeller is opened by wind, plays leakage wind action, and the impeller on this limit is the effect of wind-engaging power not; The impeller of another side is blocked by bottom end rail 4, and the impeller wind-engaging power effect on this limit, in closed state, bears wind-force.Because the wind-force that two impeller 1 on rotating shaft 5 both sides bear is uneven, therefore two impeller 1, centered by rotating shaft 5, wholely produce rotation, used dexterously lever principle, thereby the rotating shaft of rotation 5 drive wind-driven generator work.A kind of wind-driven generator novel blade of the present invention, simple in structure, be easy to manufacture, cost is low, and 360 degree utilize wind energy, and without steering system, wind energy utilization is high.
