Abstract
The utility model discloses a blade structure of a vertical axis windmill generator. The keel of the blade consists of more than two vertical tendons; the adoption of partial thickening is used for the partial enhancement of the interface of all the vertical tendons and the blade; the structure solves the problem that the original keel structure can not satisfy the requirements for the strength and rigidness of the blade of the large-scale vertical axis windmill generator; and the structure facilitates the maximization of the vertical axis windmill generator.
Description
Technical field
The utility model relates to a kind of blade structure of generator, particularly a kind of blade structure of vertical axis aerogenerator.
Background technique
Existing vane of vertical shaft wind-driven generator adopts the thin-walled hollow structure mostly, and two perpendicular muscle is set as keel in cavity, makes blade satisfy the strength and stiffness requirement; At present wind power plant is to large scale development, and we find when development large-scale (1.5MW) vertical axis aerogenerator group, only has the keel of two perpendicular muscle not satisfy the requirement of blade strength and rigidity, is unfavorable for the maximization of wind-powered electricity generation unit.
Summary of the invention
The purpose of this utility model is to disclose the blade structure of a kind of many perpendicular muscle, interface enhancement mode keel, and the keel that can overcome two perpendicular muscle can not provide the difficulty of sufficient intensity and rigidity for large-scale vertical wind-driven generator thin-walled hollow blade.
The technical solution of the utility model is: a kind of blade structure of vertical axis aerogenerator comprises the thin-walled form structure of blade and the perpendicular muscle more than two; The number of perpendicular muscle and distributing position are determined by the load of blade with to the rigidity requirement calculating of blade, perpendicular muscle is arranged in parallel, the keel of having formed blade, it is as a whole that every perpendicular muscle and the thin-walled form structure of blade all are connected, and at the interface all the mode by local bulged blading wall strengthen.
The technical solution of the utility model is: a kind of blade structure of vertical axis aerogenerator comprises the thin-walled form structure of blade, first perpendicular muscle, second perpendicular muscle, the 3rd perpendicular muscle; First perpendicular muscle is 322mm from the distance of the big endvertex of blade, second perpendicular muscle is 752mm from the distance of the big endvertex of blade, the 3rd perpendicular muscle is 1050mm from the distance of the big endvertex of blade, the perpendicular muscle of root is arranged in parallel, the keel of having formed blade, it is as a whole that every perpendicular muscle and the thin-walled form structure of blade all are connected, and all strengthen by thickening 4mm at the interface.
The utility model has solved the problem that original keel structure can not satisfy large-scale vertical wind-driven generator blade strength and rigidity with simple way and very low cost, helps realizing the maximization of vertical axis aerogenerator.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local at the interface structural representation that strengthens of perpendicular muscle and blade wall.
Among the figure: 1, the perpendicular muscle of the perpendicular muscle of the thin-walled form structure 2 of blade, first 3, second 4, the 3rd perpendicular muscle.
Embodiment
Embodiment:
By the technical solution of the utility model designing mould, adopt pultrusion molding process, can once-through, directly draw the blade of large-scale vertical wind-driven generator.
As: for chord length 1400mm, length is the vane of vertical shaft wind-driven generator of 80m, be provided with 3 perpendicular muscle, first perpendicular muscle 2 is that 322mm, second perpendicular muscle 3 are that 752mm, the 3rd perpendicular muscle 4 are 1050mm from the distance of the big endvertex of blade from the distance of the big endvertex of blade from the distance of the big endvertex of blade, 3 perpendicular muscle are arranged in parallel, the keel of having formed blade, every perpendicular muscle and the thin-walled form structure 1 of blade all are connected as a whole, and all strengthen by thickening 4mm at the interface.
