Abstract
The invention relates to a vertical-shaft wind-driven generator consisting of an energy obtaining device, an increasing gearbox, a generator, an inversion regulator and a rectification load. At least three blades are uniformly distributed on the radial peripheral edge of a tower rod, a shaft sleeve set is sleeved on the outer wall of the tower rod fixedly connected with the ground and is synchronously linked with the increasing gearbox by a transmission system, and a blade set support connected with a folding unit is fixedly connected on the surface of the outer wall of the shaft sleeve set; the blades are formed by sequentially connecting a plurality of mutually parallel folding units through a central shaft; and the central shaft of each folding unit is fixedly connected with a fixed blade and can be articulated with a rotary blade. The invention has the characteristics of compact structure, convenient installation, low cost, wide application range, good windward effect and the like.
Description
Affiliated technical field the present invention relates to a kind of wind power plant, especially a kind of vertical axis aerogenerator.
The background technique wind-power electricity generation is as a kind of novel energy, has characteristics such as pollution-free, environmental protection, and is cognitive and be extensive use of by people.The wind-driven generator that uses has two kinds of patterns at present, and a kind of is horizontal axis wind-driven generator, and another kind is a vertical-axis generators.In use there are problems such as cost height, installation difficulty in horizontal axis wind-driven generator, though that vertical axis aerogenerator has is easy to maintenance, blade is made easy advantage, the yawing mechanism that is used for realizing obtaining ceiling capacity from flow air is to realize functions such as control, self check by the control system of being made up of microcomputer or programmable controller.Therefore the yawing mechanism structure is comparatively complicated.
Summary of the invention the purpose of this invention is to provide a kind of vertical axis aerogenerator that can realize the self-regulated yawing mechanism simple in structure, safe and reliable.
For achieving the above object, vertical axis aerogenerator provided by the invention is made of capacitation device, step-up gear, generator, inversion regulator, rectification load, have at least three fan leafs to be distributed on tower bar outer radial periphery edge, the tower bar outer wall fixed with ground is socketed with the axle sleeve group, the axle sleeve group is by transmission system and step-up gear synchronous interaction, and the vane group frame that joins with folding unit is consolidated in axle sleeve group outer wall surface; Blade is connected to form by axis successively by the folding unit that several are arranged in parallel, in each folding unit axis with stator blade is fixed, and rotatable blade hinged.
Adopt this structure, because of each blade is mutually several angle, promptly when a part of blade was in positive upwind position, another part blade always was in an other side of vertical shaft.So the wind comes from of any direction can occur, in vertical shaft normal both sides, all can produce not reciprocity moment, produce the phenomenon of wind blows blade rotation.Because folding unit can unidirectional unlatching and closure, this moment, the folding unit of positive windward blades was all closed again, and other blades are in position against the wind, under wind action power, are in opening state.The one side force square at the blade place of therefore positive upwind position greater than the moment at other places, blade position, guarantees that also blade is in the state that rotatablely moves all the time forever.
As a further improvement on the present invention, the axis of folding unit is provided with the limit structure of rotatable blade.Limit the angle of swing of rotatable blade, be convenient in time launch under the wind.
As more step improvement of the present invention, the closed place of rotatable blade and vane group frame is provided with vibration damping sheet.Avoid when locating just down with the wind, occurring closed noise.
Characteristics of the present invention are: compact structure, easy for installation, safe and reliable, cost is low, and is applied widely, effective down with the wind.But need not the control system blade just box haul regulate automatically, can realize that wind-driven generator is in lasting working state.
Description of drawings Fig. 1 is the overall structure schematic representation of vertical axis aerogenerator of the present invention.
Fig. 2 is the structure enlarged view of the folding unit that shows as Fig. 1.
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, 2, vertical axis aerogenerator of the present invention is made of capacitation device, step-up gear 2, generator 3, inversion regulator, rectification load 4, braking device etc., three fan rectangular paddle 8 are distributed on tower bar 1 outer radial periphery edge, the tower bar outer wall that is fixed on ground is socketed with axle sleeve group 5, the axle sleeve group is by gear train assembly and step-up gear synchronous interaction, and the vane group frame 7 that is connected with folding unit 6 is cemented in axle sleeve group outer wall surface; Blade is connected to form by axis 9 successively by several folding units that are arranged parallel to each other, in each folding unit axis and stator blade 10 fixed, and rotatable blade 11 hinged.Be processed with the limit structure of rotatable blade on the axis of folding unit, limit the angle of swing of rotatable blade, be convenient in time launch under the wind.At rotatable blade and the closed place of vane group frame the plastic, rubber vibration damping sheet is installed, avoids when locating just down with the wind, occurring closed noise.
In actual the use, because of three blades are mutually 120 degree, promptly when a blade was in positive upwind position, all the other two blades always were in an other side of vertical shaft.Can realize the wind comes from of any direction,, all can produce not reciprocity moment in vertical shaft normal both sides.Because folding unit can unidirectional unlatching and closure, the folding unit of the blade that just facining the wind this moment is all closed again, and other two blades are in position against the wind, under wind action power, are in opening state.Greater than the moment at other places, two blades position, the wind blows blade is in the state of rotatablely moving to the one side force square at the blade place of therefore positive upwind position all the time forever.
Certainly mentioned rectangular paddle 8 is not limited to 3 among the present invention, can be for a plurality of.Can adopt the structure of having only a folding blade as the small-sized wind power generator rectangular paddle in addition.
The characteristics such as the present invention has compact conformation, and is easy for installation, safe and reliable, and cost is low, applied widely, and it is effective to facing the wind, but need not the control system blade just box haul automatically regulate, can realize that wind-driven generator is in the continuous firing state.
