Embodiment Construction

[0027] Such as image 3 — Figure 7 As shown, the multi-angle vertical axis wind power generator of the present invention includes a generator 22 , a base 1 , a lower pole 2 , an upper pole 21 , a lower plate 3 , a left wing 42 , a middle wing 41 , a right wing 43 and an upper plate 5 .

[0028] Such as image 3 with Figure 5 As shown, the base 1 is fixedly connected with the lower rod 2 . The base 1 and the lower rod 2 are strengthened and fixed by reinforcing ribs 11 . Eight reinforcing ribs 11 are evenly distributed around the axis of the lower rod 2 . The lower rod 2 is fixed with a lower flat plate 3 through a bearing. exist Figure 4 As shown, the lower plate 3 is in the left-right direction, and the upper end surface of the lower plate 3 is fixed with a left wing 42 , a middle wing 41 and a right wing 43 from left to right. The upper end surfaces of the left wing plate 42 , the middle wing plate 41 and the right wing plate 43 are fixed to each other by the upper...

Abstract

A multi-angle vertical axis wind turbine is a wind turbine with an axis of rotation substantially at right angles to the wind direction. The multi-angle vertical axis wind power generator includes a base, a lower pole, a generator, a lower plate, a left wing, a middle wing, a right wing and an upper plate. The shape and structure of the left wing plate and the right wing plate are exactly the same, and the left wing plate and the right wing plate are symmetrically arranged around the axis of the lower rod. The shape of the cross section of the left wing plate and the right wing plate is a plano-convex airfoil, and the inner surfaces of the left wing plate and the right wing plate are planes. The included angle ∠a between the vertical imaginary plane drawn by the line connecting the two vertices of the cross-section of the middle wing and the inner surface of the left wing is 39°-59°. The airflow near the small ends of the left and right blades of the multi-angle vertical axis wind turbine will flow from the inner surface close to the small end to the inner surface with lower air pressure near the large end, forming additional aerodynamic force to push the blades, so that the multiple Angled vertical axis wind turbines make full use of wind energy.

Description

technical field [0001] The present invention relates to a machine that converts natural wind energy into useful mechanical energy, and converts the mechanical energy into electrical energy, in particular to a wind generator with a rotation axis substantially at right angles to the wind direction. Background technique [0002] As a new type of power generation system with low price, reliable operation and no greenhouse gas emission, the installation of wind power system is increasing at a rate of more than 30% every year. Wind power has been increasingly widely used around the world, and has formed a global industry with an annual output value of more than five billion US dollars. However, the small-scale wind power generation system used for independent power supply in remote areas still needs to overcome many technical difficulties before it can be widely used. [0003] Wind turbines convert wind energy into mechanical energy and drive generators to generate electricity. ...
