Abstract

Multi-purpose vertical axis wind turbine.

Description

MULTI-PURPOSE VERTICAL AXIS WIND TURBINE Description

This invention is a wind-driven turbine transforming wind energy into rotation, producing torque much higher than that of similar known turbine units.

This invention have Small propeller diameter, and High maximum size of the surface contacting with the wind comparing with the common Horizontal - propeller Wind energy unit used in the market.

It have small size and Low weight of components so the Installation is possible in parts (each of the 3 components separately), and No necessity for construction of a special road for transportation.

It has the Wing with a constant profile and it doesnt required orientation system to the wind, and that Increase the efficiency and Decrease the electric power losses and simplify the installation of the project and the maintenance.

It has the max Pick up of wind energy in all kinds of winds, and it has Very high Wind power operating ratio, and High level of load And intensity of use.

The Installation of the generator can obtain at the base of the tower.

It has Low Influence on the environment, as Low level of noise and Small recession radius of splinters and Low danger for birds.

Produces up to 50% more electricity on an annual basis versus conventional turbines with the same swept area

Generates electricity in winds as low as 1 mph and continues to generate power in wind speeds up to 130 mph depending on the model Withstands extreme weather such as frost, ice, sand, humidity.

Easy on the eyes and ears being the only soundless wind turbine with reflecting surfaces to eliminate shadow strobing effect

Claims

Multi-Purpose Vertical Wind Turbine Claims

1 - The construction provides for a maximized wind-driven area per unit of volume and the air vortices, created by the wind, transfer the air stream from one wing to the next thus facilitating further self-acceleration of the turbine unit, (Figure 7).

2. The turbine is made entirely of pipes, an axle suitably supported by bearings depending on the turbine size, and a base of three pipes positioned at 120° in relation one to another (Figure 2), with the outer ends attached to a pipe bent into a circle with a radius R - the unit used in sizing of the entire structure, and to three vertical pipes which define the height of the turbine, 2R.

3. At there upper end, the three vertical pipes are connected to a top ring arranged in a mirror image of the base as described above, to form the frame of the unit.

The construction of only one wing is considered here due to the identical shapes of the wings.

4. Figure 1 presents the pipe items forming the internal frame of the wing.

5. Figure 1, 2, 3, 4 and 5 are placed in the same plane, while pipe sector 6 is a spatial curve bent sideways and comprising ¼ of a circle.

6. Figure 2 is an overview of the internal frame and shows the vertical positioning and fastening of the units in Figure 1 to the base and the fixing of sector 6 to the upper ring pipe.

7. The outer contour, figure 3, is a partial ring shape 1 and a helically bent pipe 3.

8. The contour starts with Figure 1 positioned at 90°30' in relation to the inner frame, and the helical pipe ends against the upper pipe of the top base, to which sector 6 is fixed.

9. The assembly work involves the use of three types of details - Φ16 x 1.5 pipes (figures 4, 5 and 6).

10. All connections are riveted. UV protected polycarbonate sheets would be the most suitable wing-skin material, its thickness depending on the turbine size. Additional strengthening ribs would be required for sizes above R2, 000.
