Description

WIND ENERGY CONVERSION APPARATUS
(Wind Power Energy Collecting/Conversion Apparatus)
Field of the Invention
The present invention relates to wind turbines, and in particular, although not exclusively to apparatus for converting the energy of the wind into mechanical energy.
Background to the Invention
Conventional apparatus for converting wind energy to electricity involves the use of wind turbines in which a rotatably mounted fan is rotated by the wind, in turn, rotating a shaft of a turbine so as to produce electricity.
Examples of known wind turbines include US 4,414,477 and US 6,309,172. Referring to US 4,414,477 a fan is freely rotatably mounted on a column, the fan comprising of a plurality of circumferentially spaced blades.
An annular body surrounds the centrally mounted fan, this annular body being shaped so as to assist in directing and accelerating the wind onto the blades of the turbine.
In order to be effective, the wind turbines of the prior art are required to be mounted in an elevated position above ground level so as to catch sufficient wind. Typically, therefore conventional wind turbines are mounted on long columns or shafts which introduce various disadvantages. Firstly, a wind turbine suspended high from the ground may be unsightly. Additionally, where the fan or surrounding body is damaged, repair of the wind module may not be easy. Further, exposed wind turbines may be subject to vandalism.
What is required therefore is a wind turbine configured for use in the generation of electricity from the energy of the wind without the above disadvantages.
Summary of Invention
Accordingly, the inventors provide a wind turbine module configurable for positioning within a building, structure or body being operative for use in the generation of electricity from the energy of the wind being incident on the building, structure or body.
According to one aspect of the present invention there is provided apparatus for converting the energy of the wind into mechanical for use in the generation of electricity, said apparatus comprising: a rotatably mounted fan, said fan comprising a plurality of blades mounted on a central turntable fixed to a central spindle; directional means positioned so as to partially surround the said fan, said directional means defining at least one outermost aperture and at least one innermost aperture, the outermost aperture comprising a greater cross- section than said innermost aperture wherein said directional means is configured to accelerate the wind speed and direct the wind towards said fan; and at least one support configured for supporting said directional means, said support being mountable within a building.
According to a second aspect of the present invention there is provided a building configured for converting the energy of the wind into mechanical energy for the use in the generation of electricity, said building comprising: at least one aperture formed in an exterior surface of the said building, said aperture configured to allow wind to pass from the exterior of the building into an interior of the building; a rotatably mounted fan, said fan comprising a plurality of blades mounted from a central turntable mounted to a central spindle; directional means positioned so as to partially surround said fan, said directional means defining at least one outermost aperture and at least one innermost aperture, the outermost aperture comprising a greater cross-section than said innermost aperture wherein said directional means is configured to accelerate the wind speed and direct the wind towards said fan; and at least one support configured for supporting said directional means, said support being mountable within a building.
Preferably, the directional means comprises a plurality of curved directional fins, a cross sectional area between adjacent fins decreasing from the outermost aperture to the innermost aperture.
Alternatively, the directional means comprises a plurality of curved directional fins, or if there is space the cross sectional area between adjacent fins staying the same from the outermost aperture to the innermost aperture so the winds flow does not slow down.
Preferably, the blades of the said fan are curved wherein when said fan is positioned adjacent said directional means, the directional of curvature of each blade of the fan is opposed to the direction of curvature of the directional means. -3..
Alternatively, the fan blades configured to collect the energy from the wind comprise any specific design or material being solid, semi solid or aerodynamic blades.
According to a specific implementation, the support is configured to enable positioning of the directional means adjacent at least one aperture of a structure wherein passing through the at least one aperture of the structure is channeled and accelerated via the directional means towards the fan located within the structure.
Preferably, the structure or building comprise a plurality of vents located between a portion of the roof and at least one side wall of the structure or building. The vents may be specifically configurated to direct the wind towards the directional means which in turn directs the wind towards the centrally mounted rotatable fan. The vents of the building may extend a width of the building substantially across at least one face or all faces or walls of the building.
Alternatively, the vents may be positioned at each outer wall of the building wherein wind, incident on any wall of the building, is allowed to flow into the directional means via the vents.
Preferably, this apparatus is built on the top of the main building as a separate unit although built with the building, so that the main building is sealed from the apparatus to prevent small objects, insects and the like from entering the building via the vents, may be sealed before the apparatus is built on to the building.
Where the apparatus of the present invention is positioned within a building, the guiding fins, in the form of curved walls, may be positioned between an upper and lower floor and may be configured to support the upper floor within the building. Accordingly the guiding walls configured to guide the wind from the exterior of the building or structure onto the rotatable mounted fan, may extend the full height between the upper and lower floors.
Where the apparatus of the present invention is positioned in close proximity to the roof ofa building, the roof overhang of the building of the present invention may be larger than existing roof overhangs so as to create additional vents so as to channel a greater amount of wind through the vents in the building exterior and into the directing means and ultimately onto the
rotatable fan.
Additional directing means may be provided on the building or structure, such as a lean-to building serving as a guide to increase the amount of wind channeled through the vents of the building exterior.

Detailed Description
There will now be described by way of example a specific mode contemplated by the inventors. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to
unnecessarily obscure the description.
Figures Ia and lb herein illustrates an exploded perspective view of the wind turbine apparatus according to the specific implementation of the present invention comprising notably mounted fan 100; directional means 103 and support 104.
Rotatable fan 100 comprises a centrally positioned spindle 101 and a plurality of curved blades 102 extending transverse to the axis with a space allowing the wind to flow through. Each blade 102 is substantially equal in length and height. According to the specific implementation of the present invention each blade comprises a single radius of curvature extending along its length.
The directional means is formed from a plurality of fins 103. each fin comprises a radius of curvature extending long its length. The plurality of fins are positioned to extend radially outward from on a central portion configured to accommodate the rotatably mounted fan, being similar to the spokes of a bicycle wheel extending from the central hub. Importantly, the directional fins 103 are arranged to allow the fan 100 to freely rotate when mounted centrally amongst the fins 103.
Figure 2 herein is a plan view of the wind turbine apparatus of fig I and 2 herein. Directional fins 103 comprise a length allowing the wind to reach the fan blades 102 without losing any of the winds power so as to define extended channels 200.
Directional fins 103 are mounted on a support 104 configured to provide a means for supporting fins 103 in position around fan 100. Support 104 is formed as a cage in which the directional fins 103 may be supported along a first/or a second edge extending a long length. The support 104 may be an open cage or formed by a first substantially planar upper member ( e.g. an upper floor of a building) positioned opposed to a substantially planar lower member ( e.g. a lower floor of a building), the upper and lower members sandwiching the directional finsi 03 therebetween.
By configuring the directional means 103 with a much greater length relative to the length of the fan blades 102, directing channels 200 are provided so as to sufficiently accelerate the velocity of the wind and direct the wind onto the fan blades 102.
In use, wind incident onto the apparatus enters each directional channel via outermost aperture 106. Due to the curvature of the directing fins 103 and length of the directional channel 200, the wind speed is accelerated as a result of the decreasing cross sectional surface area from the outermost aperture 106 to an innermost aperture 105 of the directing channel 200.
The accelerated wind passing through aperture 105 of reduced cross section to outermost aperture 106, is incident on fan blades 102 causing central spindle 101 to rotate about its central axis, the spindle 101 being connected to or forming part of a conventional, known generator for the conversion of mechanical energy into electricity.
Referring to figure 3a herein is a front elevation view of a house comprising a plurality of vents; Figure 3b herein is a side elevation view of a building comprising a plurality of vents, also showing space for a increase size of the wind turbine apparatus according to a specific implementation of the present invention, which allows for the increased area of vents as in 4b; Figure 4a herein illustrates a cross section side elevation view of vents 303 being positioned adjacent aperture 106 of the directional means supported by support 104. Air incident onto the building and vents 303 is allowed to pass from the exterior of the building to an interior via the gaps between the vent blades.
Figure 4b herein illustrates an alternative cross section side elevation view of vents 303 being positioned adjacent aperture 106 of the directional means supported by support 104. Air incident onto the building and vents 303 is allowed to pass from the exterior of the building to an interior via the gaps between the vent blades.
Figure 5a herein illustrates the apparatus of the present invention positioned top of a roof of a structure or conventional building 300. According to this specific implementation, the apparatus of the present invention is useable with any conventional building or structure unmodified to accommodate the apparatus of the present invention.
Figure 5a herein illustrates an alternative apparatus of the present invention positioned top of a roof of a structure or conventional building 300.
