Abstract

A water wheel type fluid flow machine comprises vanes or paddles which have a hinge at one edge to allow them to swing through up to 180 degrees. The vanes are arranged such that they present a large surface area and maximum resistance to the flow of wind or water at one phase of the revolution of the wheel and then freely and automatically pivot to present a thin profile edge to the flow 180 degrees later in the wheel revolution, resulting in the vane trailing horizontally in line with the flow and presenting minimum resistance. Limiting devices may be used to limit the angular rotation of the vanes. The vanes may be mounted on or across one or more wheels or spokes. Due to the unequal pressure on opposite sides of the wheel, this design ensures that rotation and high torque drive occurs even when totally immersed in a fluid flow, and the torque produced may be utilised to rotate a central shaft.

Description

Page 1 Vane Wheel
Background
This invention relates to a wheel with pivoting vanes.
Water wheel design drive assemblies are very efficient for capturing drive forces on their large surface area paddles but their disadvantage is that if fully immersed in water or air the forces equalise on both sides of the wheel and they cease to rotate.
Statement of invention
To overcome this immersion limitation the present invention proposes a water wheel type design wherein the wheel or paddles hinge freely across one edge to allow them to swing through up to 180 degrees such that they present a large surface area and maximum resistance to the flow of wind or water on one side of the revolution of the wheel and then freely and automatically pivots through up tol8O degrees to present a thin profile edge to the flow on the other side of the wheel revolution resulting in vane trailing horizontally in line with the flow thus presenting minimum resistance. Due to the unequal pressure on opposite sides of the wheel, this design ensures that rotation and high torque drive occurs even when totally immersed in water or air flow.
Advantages Ability to present larger surface areas within a wheel of a given diameter to absorb energy then is possible with propeller blade type drives and is therefore significantly more efficient.
This design will work automatically with flow of wind and water from any direction.
Due its design flow this device will work in a current of air or water approaching from any direction.
This device will always rotate in the same direction whatever direction air or water current is flowing.
This device can be utilised equally as effectively in a horizontal or a vertical plane.
Page 2 Device can utilise paddle vanes in a configuration that is short and wide, for examples in rivers that are wide and shallow.
It can be tall and narrow for rivers that are narrow and deep.
Device can be smaller, wide and low profile for wind driven applications thus presenting much less of a visual environmental impact.
Introduction to drawings
An example of the invention will now be described by referring to the accompanying drawings: -Figure 1 shows a horizontal spoke wheel type example according to the invention.
-Figure 2 depicts a vertical embodiment of this device.
-Figure 3 shows an example with an additional outer pin in the design which limits vane pivot away from the stop pin.
Detaile description:
Referring to Figurel -example showing air or water flowing in right to left direction with vanes mounted on a spoke type assembly around a central hub. This could equally be a disk or wheel assembly as shown in Figure 2.
At position 1, pressure is forcing vane I to pivot around points (B) at outer edge and against a stop point, in this example a stop pin, positioned towards the inner edge of vane but any suitable similar limiting mechanism could be employed, for instance a bar across the length of the vane or a pivot that will only move between a fixed angle width.
In this position (1), a vane is presenting full surface area to the flow offering maximum resistance. Resulting pressure will rotate complete assembly anti-clockwise around centre shaft A. Page 3 On opposite side of assembly, at Vane 3 position, as the wheel moves vane juts past the horizontal position, the same flow direction will have now be pushing up and against the angled vane and away from the inner stop pin which will result in the vane being pushed over through degrees until it trails in the current in a mirrored horizontal position away from stop pin. In this position the vane offers minimum resistance to flower and will trail in line with the flow like a flag.
This difference in resistance on each side of assembly is always present resulting in the assembly always being driven by flow of wind or water in either direction irrespective of whether the device is installed in the horizontal or vertical plane.
Position 2 show vane lifting and rotating around its pivot point and away from the stop pin.
Position 3 shows a vane that has been rotated 180 deg anti-clockwise around its pivot point by flow and is trailing in line with the flow so is not offering resistance to water wheel main body rotation.
Position 4 continued rotation of wheel along with water flow has now lifted vane 4 up against the stop pin. In this position it wil be beginning to add drive to the wheel.
Referring to figure 2: This shows a vertical plane embodiment of this invention. It will operate in exactly the same way as example one except for the fact that it will use the angled flow from one side to rotate the non-drive side vane (2) over 180 degrees rather than pressure from below as in the first
example.
Referring to figure 3 -This embodiment shows a design where an second stop pin has been put in to limit the vane so that it rotates more than 90 degrees but less than 180 degrees. A design with eight vanes is depicted to more clearly demonstrate the affect this has.
Flow depicted by arrow (E) is exerting force on vane in position 1 pushing against inner stop pin (C) thus causing wheel to rotate counter clockwise. Vane 2 is at an angle that is still subject to pressure on its upper surface and is also driving wheel in counter-clockwise direction.
Vane 3 has just past the horizontal position and as a result, flow now pushing on its angled lower surface has made it rotate around its pivot point (A) but it has been prevented by its outer stop pin (B) from reaching the horizontal position but is now held at an angled position such that flow is exerting force on its new supper surface at an angle to cause further counter-clockwise rotation. This force is continuing at vane position 4.
At position 5, vane has moved away from both stop pins due to flow and is in the trailing flag' position with its edge on to the flow. Position 6 shows vane still n the trailing non drive position but it is nearing the inner stop pin as it rotates. At position 7 and 8 it is against the inner stop pin again and is driving the wheel. Cycle starts again when position 1 is reached.
