Abstract
The utility model relates to a vertical axis wind turbine, which comprises a generator and a main fan blade connected onto a central shaft, wherein multiple layers of auxiliary fan blades are also connected onto the central shaft. According to the vertical axis wind turbine, on the basis of a phi-shaped main fan blade of a general vertical axis wind turbine, a double-layer semi-circular auxiliary fan blade arranged in a central position is additionally arranged, so that wind from any direction can be acted on one auxiliary fan blade, a moment is generated to drive the auxiliary fan blade to rotate, the function of low-wind start is realized, and the wind turbine is easier to start.
Description
Technical field
The utility model relates to a kind of wind-driven generator, relates in particular to a kind of vertical axis aerogenerator.
Background technique
The fan blade of general vertical axis aerogenerator is 2 or 3 main blades, and radius is big, own wt is big, need could rotate under the wind speed environment more faster, and the suitable environment scope is little, and wind-driven generator is not easy to start.
The model utility content
The utility model provides the vertical axis aerogenerator that a kind of simple in structure, low wind speed starts, cost of production is low in order to overcome the above problems.
The technological scheme of the utility model is: comprise generator and be connected the main blade on the central shaft, also be connected with the auxiliary fan blade of multilayer on the described central shaft.
Described auxiliary fan blade is divided into two-layer being connected on the central shaft, and every layer of auxiliary fan blade is three.
Described two-layer auxiliary leaf blade alternatively up and down is connected on the central shaft, and described auxiliary leaf blade is semi-circular fan blade.
The utility model is on the Φ type main blade basis of common vertical axis aerogenerator; Increased the double-deck semi-circular auxiliary fan blade that is positioned at the central position; Manage-style from which direction is not come like this, all can act on wherein on the auxiliary fan blade of a slice, produces moment and promotes auxiliary fan blade and rotate; Realize the effect that low wind starts, can make wind-driven generator be easier to start.
