Abstract
The utility model provides an aerogenerator blade. The purpose of the utility model is to solve the problem that an existing aerogenerator blade is made of glass fibre injection, a cross section of the existing aerogenerator blade is not gradient, the existing aerogenerator blade has a short life, especially the existing aerogenerator blade can not easily drive a generator shaft by wind power and can not make effective use of wind energy conversion. Comprise : the cross section is a hollow scalene blade, three edge of the hollow scalene blade are arc-shaped. The aerogenerator blade is a light alloy scalene shape, the aerogenerator blade can easily drive the generator when a windward side is pushed by wind power, can make effective use of wind energy conversion and makes full use of wind resources, especially under long-term strong wind effectively reduce the wind on the blade wear, the aerogenerator blade is advantaged by small force, less material, not easily broken, and long service life.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, belongs to the generator blade technical field.
Background technique
Used for blades of wind driven generator is in accepting wind-force and transferring electric energy to through head; Be that wind-driven generator is the vitals of electric energy with wind energy transformation; The blade of existing wind-driven generator is to adopt the glass fibre molding and forming mostly, and the cross-section is the face of no gradual change, has the problem of lacking working life; Particularly do the time spent and can not drive generator shaft easily and rotate, can not effectively utilize wind-force to carry out transformation of energy in the wind-engaging force urges.
Summary of the invention
The purpose of the utility model be for the blade that solves existing existing wind-driven generator be to adopt the glass fibre molding and forming mostly; And the cross-section is the face of no gradual change; There is short problem in working life; Particularly do the time spent and can not drive generator shaft easily and rotate, can not effectively utilize wind-force to carry out the problem of transformation of energy, and then a kind of blade of wind-driven generator is provided in the wind-engaging force urges.
The purpose of the utility model realizes through following technological scheme:
The utility model comprises: section is hollow scalene flabellum, and three limits of said hollow scalene flabellum all have circular arc.
The generator blade of the utility model is the scalene shape that light alloy is processed, and does the time spent when windward side wind-engaging force urges and can drive the generator rotation easily, effectively utilizes wind-force to carry out transformation of energy; Make full use of wind-resources, especially can stand long-term strong wind action, effectively alleviate the wearing and tearing of wind-force blade; Have stressed little; Materials are few, easy-rupturing not, the advantage of long service life.
Description of drawings
Fig. 1 is the cross-sectional configuration schematic representation of a kind of blade of wind-driven generator of providing of the utility model mode of execution;
Fig. 2 is the structural representation of wind-driven generator.
Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed mode of execution, but the protection domain of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technological scheme.
A kind of blade of wind-driven generator as shown in Figure 1, that present embodiment is related comprises that section is hollow scalene flabellum 2-1, and three limits of said hollow scalene flabellum 2-1 all have circular arc 2-1-1.
Further, also comprise two supporting frame 2-1-2, said two supporting frame 2-1-2 are arranged in parallel in hollow scalene flabellum 2-1.
The generator blade of present embodiment is the inequilateral hollow triangle shape that light alloy is processed; Thereby alleviate the weight of blade itself; All there is circular arc on its blade three limits; Blade interior is provided with two supporting frames to the inclination of the same side, one side, can make its blade firmer, and the bearing strength of wind-receiving face is more powerful.
As shown in Figure 2; The generator blade of present embodiment is installed on the following wind-driven generator: described wind-driven generator comprises: fan blade 1, external wind wheel 2 (being hollow scalene flabellum 2-1), magnetic suspension generator 3, down interior fan blade 4, blower fan fixed base 5 and external wind wheel fixing frame 6 in going up; Fan blade 1 is arranged on the upside of external wind wheel fixing frame 6 in going up; Fan blade 4 is arranged on the downside of external wind wheel fixing frame 6 down; The downside of fan blade 4 is provided with blower fan fixed base 5 down, and between fan blade 1 and the down interior fan blade 4, external wind wheel 2 was connected with external wind wheel fixing frame 6 in magnetic suspension generator 3 was arranged on.Said external wind wheel 2 is formed by three, and three external wind wheels 2 are equilateral triangle and distribute.
The above; Be merely the preferable embodiment of the utility model; These embodiments all are based on the different implementations under the utility model general idea, and the protection domain of the utility model is not limited thereto, and any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
Claims (2)
1. a blade of wind-driven generator is characterized in that, comprising: section is hollow scalene flabellum, and three limits of said hollow scalene flabellum all have circular arc.
2. blade of wind-driven generator according to claim 1 is characterized in that, also comprises two supporting frames, and said two supporting frames are arranged in parallel in hollow scalene flabellum.
