Abstract
The invention discloses a double-blade wind power generation windmill suitable for breeze. The wind power generation windmill comprises a windmill shaft sleeve and windmill blades; the windmill shaft sleeve is connected with the windmill blades; each windmill blade comprises beams, guard plates, partition sleeves, shafts, a rotating shaft and four-blade windmills; the windmill blades are connected with the beams by the rotating shafts; the shafts are connected between the beams; the shafts are connected with the four-blade windmills; each partition sleeve is arranged between each two four-blade windmills; the rotating shafts rotate to regulate angles between the windmill blades and the windmill shaft sleeve; and the four-blade windmills rotate to drive the windmill blade to rotate under the blow of breeze. The wind power generation windmill disclosed by the invention can be driven by breeze; in the case of strong wind, the intensity of a windward side of the windmill is improved, so that generating efficiency is higher; and the double-blade wind power generation windmill suitable for breeze has a simple structure and is easy to implement.
Description
Technical field
The present invention relates to technical field of wind power generation, particularly relate to the double leaf wind power generation windmill that a kind of gentle breeze adapts to.
Background technique
Existing tens thousand of wind energy conversion systems are in operation in the world, bringing into play this huge effect as supplementary energy, but still there are some deficiencys in wind energy conversion system, is at first that energy output is unstable, particularly the utilization ratio of large scale wind power machine is low, as the condition of separate energy source, does not also possess; Secondly, the safety reliability of wind energy conversion system there is no abundant guarantee; In addition, the cost of wind energy conversion system still is not enough to compete mutually with mineral fuel in a short time.
In order to solve energy output unstable problem, the invention provides the oscillating wind windmill that a kind of gentle breeze adapts to.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the oscillating wind windmill that a kind of gentle breeze adapts to.
The technical solution adopted in the present invention is: the double leaf wind power generation windmill that a kind of gentle breeze adapts to, described power generation windmill includes windmill axle sleeve, air vane, the windmill axle sleeve connects air vane, air vane includes crossbeam, backplate, partition cover, axle, rotating shaft, four leaf wind sheets, air vane connects described crossbeam by rotating shaft, be connected with axle between crossbeam, be connected with four leaf wind sheets on axle, be equipped with between every two four leaf wind sheets and cut off cover, rotating shaft is rotated and is adjusted air vane and windmill axle sleeve angle, and four leaf wind sheets rotating drive air vane under a gentle wind springing up rotates.
Compared with prior art, the invention has the beneficial effects as follows:
1. very faint wind just can drive this wind power generation windmill;
2. while blowing hard, increased the windward side intensity of windmill, generating efficiency is higher;
3. simple in structure, be easy to realize.
The accompanying drawing explanation
The axle that waits of the oscillating wind windmill that Fig. 1 is a kind of gentle breeze adaptation is surveyed view;
The plan view of the oscillating wind windmill that Fig. 2 is a kind of gentle breeze adaptation;
The partial enlarged drawing that four leaf wind sheets of the oscillating wind windmill that Fig. 3 is a kind of gentle breeze adaptation are connected with the partition axle sleeve;
The B-B sectional view of the oscillating wind windmill plan view that Fig. 4 is a kind of gentle breeze adaptation;
The C-C of the oscillating wind windmill plan view that Fig. 5 is a kind of gentle breeze adaptation analyses and observe.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is further described, and this embodiment, only for explaining the present invention, does not form and limits protection scope of the present invention.
As Figure 1-5, the present invention is the oscillating wind windmill that a kind of gentle breeze adapts to, described power generation windmill includes windmill axle sleeve 9, air vane 8, described windmill axle sleeve 9 connects air vane 8, described air vane 12 includes crossbeam 1, backplate 2, cut off cover 3, axle 4, rotating shaft 6, four leaf wind sheets 7, described air vane 8 connects described crossbeam 1 by rotating shaft 6, be connected with axle 4 between described crossbeam 1, be connected with four leaf wind sheets 7 on described axle 4, be equipped with between every two described four leaf wind sheets 7 and cut off cover 3, described rotating shaft 6 is rotated and is adjusted air vane 8 and windmill axle sleeve 9 angles, described four leaf wind sheets 7 rotating drive air vane 8 under a gentle wind springing up rotates.
Preferably, for avoiding described power generation windmill in production and processing and safeguarding that operational phase do not destroy four leaf wind sheets, the blade end 7-1 length of described four leaf wind sheets 7 is not higher than the height of the bottom surface 1-1 of crossbeam 1.
Preferably, for increasing the swinging strength of four leaf wind sheets, between described four leaf wind sheets 7 and partition cover 3, leave gap 10, described gap 10 is not less than 0.5mm.
Preferably, backplate 2 is used high-strength bolt 5 to be connected on crossbeam 1 to guarantee its intensity.
Preferably, air vane 8 materials are the working strength that carbon fiber-reinforced resin has not only guaranteed windmill, and have alleviated the weight of windmill, have reduced the frontal resistance of windmill, are to obtain one of key factor for windmill obtains wind-force.
Further, the present invention has adopted 5 four leaf wind sheets of shape less through the same axis, and three same parallel axes are connected to the structural type on the air vane framework, two air vanes 8 that are connected on windmill axle sleeve 9 are asymmetric about windmill axle sleeve 9, the deficiency of windmill generating when this structure has made up little wind or gentle breeze also can produce larger electric weight when little wind or gentle breeze.
The oscillating wind windmill that a kind of gentle breeze of the present invention adapts to, when little wind or gentle breeze, at first utilize the weight effect of two asymmetric air vanes to swing, with this simultaneously, four leaf wind sheets 7 on air vane are because weight is lighter, swing easily the swinging strength that has increased air vane 8 under gentle breeze, thereby produce larger electric weight.
With existing wind power generation windmill, compare, the oscillating wind windmill structure that gentle breeze proposed by the invention adapts to is simple, be easy to realize, and very faint wind just can drive this wind power generation windmill; When blowing hard, increased the windward side intensity of windmill, generating efficiency is higher.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily, according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
