Abstract
The utility model discloses a blade and a generator with the blade. The blade comprises a rotating shaft, at least two fan blade bodies, a horizontal support and a vertical support connected with the horizontal support. Each fan blade body comprises a front section and a rear section. The cross section of the front section is of a semicircular or semi-oval or arc structure. The cross section of the rear section is of an arc structure. The sectional area of the front section is smaller than that of the rear section. The two ends in the horizontal direction of each fan blade body are fixedly connected with banding strips. The vertical support is fixedly connected to the two ends in the vertical direction of the blade. The blade is simple in structure. The front section of the front surface of each fan blade body is of an inwards concave semicircular or semi-oval or arc structure, so that the resistance to wind is large; oppositely, when each fan blade body rotates by 180 degrees, the front section of each fan blade body becomes outwards convex, and the resistance to wind is small; as a result, when the generator is started, the resistance to wind of the front surface of each fan blade body is much larger than the resistance to wind of the back surface of each fan blade body, and therefore the purpose that the generator can be started through a breeze is achieved.
Description
Technical field
The utility model belongs to a kind of technical field of wind power generator, relates in particular to a kind of blade and the generator of this blade is installed.
Background technique
The device that wind-driven generator is is electric energy by wind energy transformation, mainly by blade, generator, mechanical part and electric component form.According to the difference of running shaft, wind-driven generator is mainly divided into horizontal axis wind-driven generator and vertical axis aerogenerator two classes, and horizontal axis wind-driven generator accounts for position of mainstream in the market.
The blade of existing vertical axis aerogenerator is generally resistance S type and easily starts.Lift aerofoil profile, H type, wine bucket-type rotating speed are fast, and make axis wind power generator structure relative complex, and the cost of vertical shaft electric machine is high relatively, and this has all restricted the application of vertical axis aerogenerator.
Model utility content
For the deficiency of above-mentioned technology, the utility model provides a kind of has resistance type easily to start and the fast blade of lift-type rotating speed
To achieve these goals, the utility model is to solve the problems of the technologies described above taked technological scheme to be:
A kind of blade, the vertical support frame that comprises a rotating shaft, at least two flabellums, at least two horizontal stands and connection horizontal stands, described flabellum comprises leading portion part and back segment part, described leading portion part cross section is semicircle, half elliptic or arcuate structure, described back segment part cross section is arc-shaped structure, leading portion partial cross section is long-pending, and to be less than back segment partial cross section long-pending, two-part structure that is combined into one.The center of each described horizontal stand is all connected in rotating shaft, at the two end part of the substantially horizontal of flabellum, is connected with hoop bar, at the two end part of the Vertical direction of flabellum, is connected with vertical support frame.
The angle of each described horizontal stand is 30 °-90 °.
A generator with above-mentioned blade, comprises framework, wind generating unit and blade, and blade and electricity generating device are installed on described framework, and blade drives wind generating unit generating.
Described framework comprises that top and bottom are lambdoid A-frame, on the top of A-frame, solar panels is installed, and described solar panels are connected with described wind generating unit, and described solar panels are mounted obliquely within on described A-frame.
Described framework comprises that a cross section is the shape of the mouth as one speaks support of square shape, top, upper end at described shape of the mouth as one speaks support is provided with solar panels, described solar panels are connected with described wind generating unit, and described solar panels are mounted obliquely within on described shape of the mouth as one speaks support.
Described framework comprises the supporting frame of an installation blade, and described supporting frame is hinged on a underframe, and described wind generating unit is arranged on described underframe.
The beneficial effects of the utility model: the utility model is simple in structure, the front leading portion of its flabellum partly adopts semicircle or half elliptic or the arcuate structure of indent, its resistance to wind is larger, on the contrary, after 180 ° of flabellum runnings, the leading portion part of flabellum just becomes convex shape, and its resistance to wind is less, so while starting flabellum just in the face of the resistance of wind much larger than the back side resistance to wind, to reach the object that gentle breeze can starter-generator.
Accompanying drawing explanation
Fig. 1 is that employing two flabellums of the present utility model and two horizontal stand angles are the structural representation of 90 °.
Fig. 2 is embodiment 1 frame structure schematic diagram.
Fig. 3 is embodiment 2 frame structure schematic diagram.
Fig. 4 is embodiment 3 frame structure schematic diagram.
Embodiment
In order to make the utility model be convenient to understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
Embodiment 1
As depicted in figs. 1 and 2, a kind of blade, comprise a rotating shaft 1, at least two flabellums 2, the vertical support frame 4 of at least two horizontal stands 3 and connection horizontal stand 3, described flabellum 2 comprises leading portion part 21 and back segment part 22, described leading portion part 21 cross sections are semicircle, half elliptic or arcuate structure, described back segment part 22 cross sections are arc-shaped structure, described leading portion part 21 and back segment part 22 are integral type structure, the center of each described horizontal stand 3 is all connected in rotating shaft 1, at the two end part of the substantially horizontal of flabellum 2, be connected with hoop bar 5, two end part in the Vertical direction of flabellum 2 are connected with vertical support frame 4.Described vertical support frame 4 is affixed with horizontal stand 3.
The angle of each described horizontal stand 3 is 30 °-90 °.
The utility model partly adopts semicircle or half elliptic or the arcuate structure of indent at the front of flabellum leading portion, its resistance to wind is larger, on the contrary, after 180 ° of flabellum runnings, the leading portion part of flabellum just becomes convex shape, and its resistance to wind is less, thus while starting flabellum just in the face of the resistance of wind much larger than the back side resistance to wind, because the long-pending back segment partial cross section that is less than of leading portion partial cross section amasss, make to produce inertia after startup again.To reach gentle breeze, get final product the object of starter-generator.
