Abstract
This invention provides an apparatus and a method for generating power from a flowing liquid. The apparatus has three main components. The first component is a control unit for selectively directing the flowing liquid to the second component, the power unit, which is responsible for generating power. The third component, a reversing unit, is used to adjust the control unit between two control unit configurations. The method involves the manner in which the liquid is passed and directed through the apparatus in order to generate power.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to the production of power, and more particularly to an apparatus and method for generating power by utilizing the force of a flowing liquid.




The need to generate power in times of crisis and the need to generate power from a relatively inexpensive resource have long been felt. Inventors have tried for some time to create an apparatus and method that will generate power for little cost. The ability to generate power from an inexpensive resource when access to traditional power, namely power supplied by a power company, is not available due to power shortages or natural disasters is needed.




Also, in times when emergency power is not required, the ability to generate such power assists in preserving the environment by lessening the burden on power companies to provide power, and the ability to generate power would save consumers money on monthly electric bills. The need to generate power from an inexpensive resource will become of even more importance as other more expensive resources of the world dwindle and disappear over the course of time.




There have been attempts in the prior art to harness the kinetic energy of a flowing liquid in order to generate power. However, these attempts are either impractical, difficult to scale, difficult to distribute, awkward to use, or simply will not work. Therefore, an apparatus and method are needed that generates power from a flowing liquid.




SUMMARY OF THE INVENTION




This invention provides an apparatus and a method for generating power from a flowing liquid. The invention provides an apparatus comprising a control unit selectively operable between a first control unit configuration and a second control unit configuration for receiving the flowing liquid and selectively directing the flowing liquid to a first power unit aperture when the control unit is in the first control unit configuration, and selectively directing the flowing liquid to a second power unit aperture when the control unit is in the second control unit configuration; a power unit for generating power, including: (1) a power chamber having the first power unit aperture for receiving the flowing liquid from the control unit, and a second power unit aperture for receiving the flowing liquid from the control unit, (2) a power operator operable between a first power operator position and a second power operator position and disposed within the power chamber, operatively configured so the power operator becomes disposed in the first power operator position when the control unit is disposed in the first control unit configuration, and so that the power operator becomes disposed in the second power operator position when the control unit is disposed in the second control unit configuration, and (3) a power transmission linkage operatively communicating with said power operator for transmitting power as said power operator reciprocates between said first power operator position and said second power operator position; and a reversing unit to adjust the control unit configuration to become disposed in the first control unit configuration when the power operator becomes disposed in the second power operator position, and to adjust the control unit configuration to become disposed in the second control unit configuration when the power operator becomes disposed in the first power operator position.




The invention provides a method comprising passing the flowing liquid to a control unit selectively operable between a first control unit configuration and a second control unit configuration; directing, selectively, the flowing liquid to a first power unit aperture when said control unit is in said first control unit configuration, and selectively directing said flowing liquid to a second power unit aperture when said control unit is in said second control unit configuration; forcing a power operator operable between a first power operator position and a second power operator position and disposed within the power unit, to the first power operator position when receiving flowing liquid from the first power unit aperture and to the second power operator position when receiving flowing liquid from the second power unit aperture; transmitting power through a power transmission linkage operatively communicated with the power operator as said power operator reciprocates between the first power operator position and the second power operator position; and directing the flowing liquid to a reversing unit to adjust the control unit configuration to become disposed in the first control unit configuration when the power operator becomes disposed in the second power operator position, and to adjust the control unit configuration to become disposed in the second control unit configuration when the power operator becomes disposed in the first power operator position.

FIGS. 3 through 11

illustrate the manner in which a preferred apparatus and method of this invention generates power from a flowing liquid. The manner in which this preferred apparatus operates may be explained by beginning at any of FIG.


3


through FIG.


10


. For the sake of simplicity, the process is described beginning with

FIG. 3

, where the control unit operator


70


is disposed in the second control unit operator position


110


. The flowing liquid enters the apparatus through aperture


20


and passes through the control unit


40


and the first control unit channel


120


into second power unit aperture


60


, forcing the power operator


160


to the second power operator position


180


. Upon reaching the second power operator position


180


, the flowing liquid is directed through the reversing unit


320


, the first reversing unit channel


380


, and the reversing unit operator


330


to the second control unit aperture


410


.




Looking at

FIG. 4

, as the flowing liquid enters the control unit


40


through the second control unit aperture


410


, the control unit operator


70


begins to move towards the first control unit operator position


100


, which forces the flowing liquid through the first control unit aperture


400


to the second reversing unit channel


390


. The flowing liquid then exits the apparatus through port


30


.




In

FIG. 5

, the control unit is disposed in the first control unit configuration and the control unit operator


70


has reached the first control unit operator position


100


, forcing the flowing liquid entering the apparatus through port


20


to travel through the control unit


40


and the first control unit channel


120


to the first power unit aperture


50


. This forces the power operator


160


to begin moving towards the first power operator position


170


. As the power operator


160


moves towards the first power operator position


170


, the flowing liquid exits the power chamber


150


through the second power unit aperture


60


to the second control unit channel


130


. The flowing liquid then exits the apparatus through aperture


30


.





FIG. 6

illustrates the movement of the power operator


160


as the power operator is forced towards the first power operator position


170


. As the power operator


160


travels to the first power operator position


170


, the power operator forces the power transmission linkage


190


to move. This movement causes the power transmission linkage to transmit power to the power generator


260


.





FIG. 7

illustrates the movement of the reversing unit operator


330


towards the first reversing unit operator position


340


. The power transmission linkage


190


contacts the first strike


430


of the yoke


420


. As the power operator


160


moves towards the first power operator position


170


, the yoke


420


forces the reversing unit operator


330


towards the first reversing unit operator position


340


. The movement of the power transmission linkage


190


continues to cause the power generator


260


to generate power.




In

FIG. 8

, the power operator


160


completely moves to the first power operator position


170


, thereby causing the reversing unit operator


330


to move completely to the first reversing unit operator position


340


. As a result, the flowing liquid entering the apparatus travels through the first reversing unit channel


380


to the first control unit aperture


400


. The flowing liquid forces the control unit operator


70


towards the second control unit operator position


110


. As a result of the movement of the control unit operator


70


, the flowing liquid exits the control unit


40


through the second control unit aperture


410


to the second reversing unit channel


390


.




In

FIG. 9

, the control unit is disposed in the second control unit configuration and the control unit operator


70


is disposed in the second control unit operator position


110


. This allows the flowing liquid to travel through the first control unit channel


120


to the second power unit aperture


60


. Simultaneously, the power operator


160


moves towards the second power operator position


180


, and flowing liquid is forced to exit the power chamber


150


through the first power unit aperture


50


to the second control unit channel


130


. As the power operator


160


moves, the power transmission linkage


190


causes the power generator


260


to generate power.




In

FIG. 10

, the power transmission linkage


190


contacts the second strike


440


of the yoke


420


as the power operator


160


proceeds towards the second power operator position


180


. The movement of the power operator forces the reversing unit operator


330


towards the second reversing unit operator position


350


. At this point, the apparatus has completed one full cycle, and the cycle begins again at FIG.


3


.





FIG. 11

illustrates a preferred method of this invention. An act is preferably passing


500


the flowing liquid to a control unit selectively operable between a first control unit configuration and a second control unit configuration for receiving said flowing liquid. Suitably, an act is directing


510


, selectively, the flowing liquid to a first power unit aperture when the control unit is in the first control unit configuration, and selectively directing the flowing liquid to a second power unit aperture when the control unit is in the second control unit configuration.




Conveniently, an act is forcing


520


a power operator operable between a first power operator position and a second power operator position and disposed within the power unit, to the first power operator position when receiving flowing liquid from the first power unit aperture and to the second power operator position when receiving flowing liquid from the second power unit aperture.




Preferably, an act is transmitting


530


power through a power transmission linkage operatively communicated with the power operator as the power operator reciprocates between the first power operator position and the second power operator position.




Conveniently, an act is directing


540


the flowing liquid to a reversing unit to adjust the control unit configuration to become disposed in the first control unit configuration when the power operator becomes disposed in the second power operator position, and to adjust the control unit configuration to become disposed in the second control unit configuration when the power operator becomes disposed in the first power operator position.
