DETAILED DESCRIPTION
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the figures illustrate one embodiment of a water and wind turbine made in accordance with the present invention. (Another embodiment is shown in my U.S. Pat. No. 8,076,791, which is hereby incorporated herein by reference.)
FIG. 1 is an illustrative view of the turbine and generator 10 in use powered by wind or water pressure. A pair of spaced apart stationary housing plates 14 have a plurality of fins 16 angularly disposed therebetween into optimum positioning for maximum driving and power. Additionally, the turbine and generator 10 may be utilized as a wind driven turbine 18 having a vane 20. In a reversed scenario, the turbine may also be utilized as a propulsion means for watercraft 12.
FIG. 2 is a side view of the wind/water turbine of the present invention in use with wind 18. The turbine comprises spaced apart stationary housing plates 14 with a main shaft 22 rotatively mounted therebetween. The main shaft is also called a main axle 42, as shown in FIGS. 6 and 8. The stationary housing plates 14 have magnetic tracks 30, magnetic guides 29 and a magnetic stud transfer guide 31 attached thereto for constraining and guiding fins 16 through a cyclical path driven by wind 18. The fins 16 are rotatively mounted to arms 36 which are fixedly attached to a main shaft 22, which is used to drive a generator. The fins 16 are shown in phantom in FIG. 2, and it can be seen that they are driven through a cycle in which they pivot from a vertical orientation to a horizontal orientation and then return to a vertical orientation. Since the track 30 is eccentric relative to the axis of rotation of the main shaft 22, it can guide the studs on the fins 16 and cause each of the fins 16 to pivot about the respective fin axis (the axis of the collar 48) as the main shaft 22 rotates.
Looking at FIG. 2, it can be seen that the fin 16 at the 9 o'clock position has its upper stud in the leading position outside of the track 30 and its lower stud in the trailing position inside the track 30. As the main shaft 22 rotates clockwise, when that fin 16 reaches the 12 o'clock position, it is in a vertical orientation. Its upper (leading) stud is on the outside of the outer guide 27, and its lower stud is between the ends 25 of the track 30. As the main shaft 22 continues to rotate clockwise, the lower stud of the fin 16 (which had been the trailing stud) enters into the inside of the track 30 and becomes the leading stud as it travels inside that track 30 until it reaches the lower gap 60 in the outer portion of the track 30, at which point it leaves the track and is guided by the guides 31 and 29 to the outside of the track 30, which also guide the other stud (which has now become the trailing stud) to the inside of the track 30. When the fin 16 reaches the six o'clock position, just before the trailing stud enters the inside of the track 30, the fin 16 has a horizontal orientation. It may also be appreciated that the fin axis 48 for each of the fins 16 follows an imaginary path 26 centered on the main axle 42, and that the track 30 is eccentric relative to the main axle 42.
FIG. 3 shows the orientation of one of the plates when the turbine is being used with wind. The fins 16 are independently moveable one from the other whereby one is driven through a vertical plane while the opposed fin 16 is driven through a horizontal plane.
FIG. 4 is a side view of one of the plates oriented for use with a flowing liquid, such as water. Shown is a turbine powered by a moving water 18 generator having magnetic fin guides 30 as a friction reduction system. The system comprises a support having magnetic tracks and guide positioned thereon whereby a main shaft 22 having arms 36 terminating in rotative fins 16 with magnetic tracks 30 constraining the fins 16 to a prescribed path 28, the inner track 24, while being driven by the water-energy to store potential energy produced from the kinetic energy of the water-energy. The fins 16 are driven through a cycle having a vertical orientation through a horizontal orientation before returning to a vertical orientation.
FIG. 5 is an illustrative view of the present invention in use with a flowing liquid. The fins 16 are independently moveable one from the other whereby one is driven in a vertical plane while the opposed fin 16 is driven in a horizontal plane.
FIG. 6 shows the main shaft 42 with a plurality of supporting arms 36 radially projecting therefrom with the distal end of each having a bearing 46 rotatively connected to a pair of fins 16, having one on each side of the arm 36, which rotates with the main shaft 42. Each fin 16 has magnetic studs 50 attached proximate to two outer corners. While one said magnetic stud 50 runs along a channel in a circular track of smaller diameter than that of the arm 36, the angle that each fin 16 rotates is controlled, in order to transfer maximum energy to the main shaft 42. It should be noted that the track need not necessarily be circular. The shape of the track may be designed as desired to achieve the optimal fin position.
FIG. 7 is a detailed view of the fin 16, arm 36 and magnetic studs 50. This wind or water powered wheel provides pairs of radially positioned arms 36 with each having a shaft with a pair of fins 16 pivotally attached thereto via a bearing 46 in collar 48. The fins 16 are independently movable from each other. One pair of fins 16 is driven in a vertical plane while the opposed pair of fins 16 is driven in a horizontal plane. Additionally shown is a pressure release gate 52 whereby under the incident of extreme weather, the fins 16 can pivot as shown in FIG. 10, to permit flow that otherwise would destroy the fin 16 if opposed.
FIG. 8 is a front view of the turbine and generator combination 10 with the generator 54 being shown connected to the main shaft 42. It can be seen in this view that the pair of fins 16 at the top are in a vertical position, while the pair of fins 16 at the bottom are in a horizontal to optimize the harvesting of energy while reducing drag.
FIG. 9 is similar to FIG. 8 but shows that the turbine may be expanded and ganged with a plurality of fins 16 and arms 36 operating on a common main shaft 42 and generator 54 as the magnets travel through the tracks 30 of the stationary plates 14.
FIG. 11 is an illustrative view of the wind or water turbine having an added cover 32. The cover 32 is placed above the wind or water turbine and prevents fluid escape.
