Vertical windmill

Abstract

The vertical windmill includes a rotatable wind wheel column mounted to a base. The column includes a plurality of hollow wheel hubs stacked vertically atop each other. Each wheel hub includes a plurality of radiating mounting arms equidistantly spaced around the axis of the wheel hub such that the arms of an adjacent hub are angularly offset with respect to the other. A plurality of mounting assemblies is disposed on each of the mounting arms for mounting an array of wing blades. Each alternate stacked wheel hub and mounting arms together forms a wind wheel with vertically oriented wing blades mounted between upper and lower spaced arms such that the top wheel is interconnected with the lower wheel at a height less than the height of the blades. Each array of blades may freely rotate or be positively rotated to orient the blades for optimum usage of wind power in rotating the column.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to alternative energy generating devices, and more specifically to a vertical windmill for maximizing conversion of wind energy into usable energy.[0003]2. Description of the Related Art[0004]Due to the ever-increasing energy demands and the negative environmental impact of fossil and nuclear fuels, pursuit of green alternatives have become a prominent concern worldwide. The supply of fossil fuels dwindles annually, and they produce tons of hazardous chemicals dangerous to dispose of without strict regulation. Nuclear reactors produce radioactive wastes that take decades before the radioactivity diminishes to safe levels. Moreover, it is difficult to find safe landfill real estate that does not encroach on livable land.[0005]With the above concerns in mind, many different alternative methods for generating usable energy have been pursued utilizing the power of the elements such as solar, wa...

Benefits of technology

[0008]The vertical windmill includes a rotatable wind wheel column mounted to a base. The column includes a plurality of hollow wheel hubs stacked vertically atop each other. Each wheel hub includes a plurality of radiating mounting arms equidistantly spaced around the axis of the wheel hub so that the arms of an adjacent hub are angularly offset with respect to the other. A plurality of mounting assemblies is disposed on each of the mounting arms for mounting an array of wing blades. Each alternate stacked wheel hub and corresponding mounting arms together forms a wind wheel with vertically oriented wing blades mounted between upper and lower spaced arms so that the top wheel is interconnected with the lower wheel at a height less than the height of the blades. Each array of blades may freely rotate or be positively rotated to orient the blades for optimum usage of wind power in rotating the column.

Problems solved by technology

The supply of fossil fuels dwindles annually, and they produce tons of hazardous chemicals dangerous to dispose of without strict regulation.

Moreover, it is difficult to find safe landfill real estate that does not encroach on livable land.

However, this particular configuration still does not maximize conversion of wind power to rotary force due to the weight of the blades despite the advantages of the aerodynamic design.

In other words, the typical windmill generator may not be able to convert the wind power from any given wind velocity with maximal efficiency because some will be lost in overcoming the mass and friction of the blades.

Moreover, it may be difficult to widely employ the typical windmill generator due to the lack of ideal windy locales and / or the size.
