Description

DEVICE TO GIVE TORQUE TO GE]NfERATOR USING WATER
TECHNICAL FIELD
The present invention relates to power generating devices and, more specifically, to a fluid driven apparatus for turning a generator.
BACKGROUND ART
Wind and water have been employed for many years as a source of mechanical energy, using a variety of fluid wheels or fluid motors to convert the movements of air or water into a rotational mechanical force. A rotational mechanical force so produced may be used directly to drive a piece of mechanical equipment, such as a water pump for irrigation or a mill for grinding grain, or indirectly by turning a generator, thereby providing electricity for a multitude of uses.
Numerous devices have been devised to harness the movement of a fluid, such as air or water, to operate an electrical generator, converting the power of the wind or a river current or the like into electrical power. Many of such devices use a plurality of blades or vanes disposed about an axis of rotation such that a fluid impacting the blades or vanes causes their movement about the axis of rotation. Often, the blades or vanes are oriented or shaped such that the surface area of each blade or vane is maximized when the blade or vane is moving in the direction of the fluid, and is minimized when the blade is moving opposite the direction of the fluid. Thus, a fluid wheel that is fully immersed within a moving fluid medium is operable because a greater force is imparted to the blades or vanes whose surface area is maximized in the fluid stream, thereby providing an asymmetric force about the axis of rotation so that the fluid wheel turns.
Fluid wheel devices have been devised for operation by a fluid medium flowing in either of a forward or reverse direction. One example is a water wheel adapted for use in a tidal current that reverses direction periodically over the course of time. Other devices have been devised to function within a fluid medium that may flow in any direction within a full 360° range. Various techniques have been employed to accommodate such a change in direction of the fluid medium, including "weathervaning", whereby the fluid wheel simply turns in orientation to align with the direction of flow of the fluid medium, and movable blades or vanes that allow operation in more than a single direction of flow. Wind or water powered generators are typically specialized in their design for operation with either air or water, but are rarely adapted in their design for use with either fluid medium.
None of the above described systems or methods for generating electrical power from movement of air or water, taken either singly or in combination, is seen to describe the instant invention as claimed. Thus, a fluid driven apparatus for turning a generator solving the aforementioned problems is desired.
DISCLOSURE OF INVENTION
A fluid driven apparatus for turning a generator has an axle with a first end and a second end and a plurality of disks disposed between the first and second ends of the axle. The disks are flat and circular shaped members having a center portion, and each disk has at least one vaned surface. A plurality of vanes are disposed on each of the vaned surfaces, wherein each vane is flat and generally rectangular in shape, having a hinged edge coupled to the vaned surface of the disk and a free edge opposite the hinged edge, the hinged edge extending radially from the center of the disk. A plurality of channels are defined between adjacent disks on the axle.
The fluid driven apparatus for turning a generator is adapted to be rotated by movement of a fluid medium, such as air or water. The fluid wheel utilizes a plurality of planar disks disposed along an axle to support hinged vanes such that a fluid current causes rotation of the fluid wheel about its axle. The rotation of the axle may be transferred directly, or by a drive transmission, such as a gear train or a pulley and belt coupling.
The planar disks are evenly spaced apart along the axle, and are oriented parallel to one another so that a plurality n of disks defines n-\ channels between the disks. A pair of adjacent disks thus defines a channel, a surface of each of a pair of adjacent disks facing a channel. The hinged vanes are disposed on the channel-facing surfaces of the disks, and are arranged in vane pairs where for each pair of vanes, a first vane is located on a channel-facing surface of one of the pair of the disks, and a second vane is located in apposition to the first on the channel-facing surface of the other of the pair of disks.
Each of the vanes is a generally rectangular member having one edge pivotally coupled to a disk surface along a radial of the disk. Each of the vanes is movable from a first position, lying generally against and parallel to the disk surface, and a second position wherein the vane stands perpendicular to the disk surface. It can be recognized that the two vanes of a vane pair cooperate with one another in the second position, essentially forming a wall across the channel along a radial. A fluid current, impinging on the wall across a channel imparts a rotational force to the fluid wheel.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

BESTMODESFORCARRYINGOUTTHEINVENTION
The present invention is a fluid driven apparatus for turning a generator, designated generally as 10 in the drawings. Referring to Figs. 1-4B, the fluid driven apparatus for turning a generator 10 is a fluid wheel, adapted to be rotated by movement of a fluid medium, such as air or water, comprising a plurality of planar disks 20 disposed along an axle 11 to support hinged vanes 41 such that a fluid current C causes rotation of the fluid driven apparatus 10 about its axle 11. The rotation of the axle 11 may be transferred directly or by a drive transmission, such as a gear train or a pulley 17 and belt 19 coupling, to an electrical generator 60 or another mechanical device.
The axle 11 is rotatably supported, in the illustrated embodiment, by a frame 50. Bearings 52 are disposed on the frame, and first and second ends 13, 15 of the axle 11 are supported by the bearings 52. The frame 50 may be adapted to support additional bearings 52 as necessary or desired for support along the length of the axle 11, such as in an embodiment of the fluid driven apparatus 10 wherein a large number of planar disks 20 are employed along an axle of such length that the axle 11 might sag without additional support.
The disks 20 are evenly spaced apart along the axle 11, and are oriented parallel to one another so that a plurality n of disks 20 defines n-\ channels 30 between the disks 20. A pair of adjacent disks 20 thus defines a channel 30 between opposing channel-facing surfaces 22 (also referred to as vaned surfaces) of the disks 20. The hinged vanes 41 are disposed on the channel-facing (or vaned) surfaces 22 of the disks 20, and are arranged in vane pairs 40 where a vane pair 40 includes a first vane 41 on a channel-facing surface 22 of one of the pair of disks 20, and a second vane 41 located oppositely from the first on the channel-facing surface 22 of the other of the pair of disks 20. In an alternative embodiment, a spoke assembly may directly connect the vanes 41 to the axel 11.
Each of the vanes 41 is a flat and generally rectangular member having a hinged edge 43 and a free edge 44 opposite the hinged edge 43 (shown most clearly in Fig. 4A), the hinged edge 43 being coupled by a plurality of hinges 45 to a channel-facing surface 22 of a disk 20 along a radial extending from the center of the disk 20. Each of the vanes 41 is movable from a first position, lying generally against and parallel to the channel-facing surfaces 22 of a disk 20, and a second position wherein the vane stands perpendicular to the channel-facing surface 22. It can be recognized that the two vanes 41 of a vane pair 40 cooperate with one another in the second position, essentially forming a radial wall across the channel 30. A fluid current C, impinging on the vanes 41 across a channel 30, imparts a rotational force to the fluid driven apparatus for turning a generator 10. The vanes 41 are hinged to swing freely between the first and second positions. For each vane 41, a vane stop 47 prevents the vane from moving past the second position, holding the vane 41 upright against the impinging fluid current C. With the fluid driven apparatus 10 fully immersed in a fluid current, such as the fluid driven apparatus 10 being submerged in a river or stream, it can be seen that each channel 30 can be considered to have an up-current side 32, and a down-current side 34, the up-current side 32 and down-current side 34 being on opposite sides of a plane lying in alignment with the direction of the fluid current and containing the axle 11. As the fluid driven apparatus 10 turns about its axle 11 to bring a vane 41 into the down-current side 34, where the vane 41 is traveling in the direction of the fluid current C with the hinged edge 43 ahead of the free edge 44, the fluid current C lifts the free edge 44 and urges the vane 41 into its second position against the vane stop 47, perpendicular to the channel-facing surface 22. Thus, the vanes 41 of a vane pair 40 are positioned on the down- current side 34 to form a radial wall between disks 20, such that the fluid current C pushes the vanes 41 to rotate the axle 11.
When a vane 41 rotates into the up-current side 32, the current impinges on the vane 41 now with the hinged edge 43 of the vane 41 ahead of the free edge 44, such that the fluid current C urges the vane 41 from its second position to its first position, wherein the vane 41 lies generally against and parallel to the channel-facing surface 22 of a disk 20. With the vanes 41 so positioned in the up-current side 32 of the channel 30, the vanes 41 present no resistance to the rotation of the fluid driven apparatus for turning a generator 10.
The fluid driven apparatus 10 may be employed in a water current, such as a river or stream or tidal current. For use in a water current, the fluid driven apparatus 10 is made from sturdy materials suitable for withstanding the stress of the water current against the vanes 41 and suitable for resisting rust and corrosion associated with water submersion. Metal, such as stainless steel, sturdy plastics or composite materials may be employed. For use in an air or wind current, the fluid driven apparatus for turning a generator 10 is made from materials with a high strength-to-weight ratio so that the weight of the fluid driven apparatus 10 is not too great for air or wind current operation. The fluid driven apparatus 10 may be used in any suitable orientation, such as with its axle 11 horizontally positioned as illustrated, or with its axle 11 vertically positioned. A vertical orientation maximizes the effectiveness of the fluid driven apparatus for turning a generator 10 in capturing a fluid flow, such as wind in any direction.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
