Abstract
A hydroelectric power generating method and/or apparatus provides one or more inlet pipes perpendicular to a flow of water in a stream or river. The inlet pipes have a length and plural apertures along the length of the at least one inlet pipe. A feedline and a turbine generator combination are interconnected with the inlet pipes. One or more outlet pipes are interconnected with the feedline and the turbine generator combination. The outlet pipes have an elevation lower than the inlet pipe. A flow of water passes through the inlet pipes, the feedline, the turbine generator combination, and the outlet pipes, and generates electricity from the flow of water passing through the turbine generator combination. The hydroelectric power generating method also provides a pressure dissipation device that causes a reduction in the pressure of the water so that the water can be released safely back into the stream or river.
Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/653,515, filed Feb. 17, 2005.
- 1. Field of the Invention
- The present invention relates generally to electric power generation and, more particularly to a hydroelectric power generating method and apparatus.
- 2. Description of the Related Art
- The constant increase in demand for electric power has resulted in various sources of electric power. Coal fired electric plants strip the land and make large pits. Nuclear power is economical but involves environmental and variable issues. Hydroelectric power is a renewable source but has some environmental and ecological effects. Typical hydroelectric power is generated through the use of dams that feed turbines and turns them for power generation. Building additional dams requires environmental and ecological studies, not to mention political questions. Turbines are based on volume and pressure depending on the height of the dam and reserve of water. What they lack in pressure, they have to make up in volume. For example, German patent DE 19544141, dated May, 1997 discusses a hydroelectric power generating system using an intake installation to remove part of the water from a flowing stream. However, unlike the present invention there exist no figures showing how to increase pressure from the inlet in a successive manner.
- Additionally, European patent EP 0036453 discusses installation of a hydro-electric turbine within a prefabricated tank, but unlike the present invention does not illustrate apparatus that advantageously uses head pressure from streams or lakes without dams.
- Similarly, Japanese patent JP 1077760 discusses an excess water discharge control device that responsive to pressure discharges excess water according to the water level in an upper dam, but, unlike the present invention, does not appear to disclose utilization of river or stream head pressure without the use of a dam.
- European patent WO 03054386 discusses placement of a turbine within a flow pipe, but, unlike the present invention, does not illustrate the construction of a piping system that advantageously utilizes stream or river head pressure without the use of a dam.
- Moreover, Japanese patent 2003201949 appears to discuss the usage of paddle wheel type generators placed in a river to avoid the use of a dam, however, unlike the present invention, does not illustrate the construction of a piping system that advantageously utilizes stream or river head pressure without the use of a dam.
- A need exists for a hydroelectric power generating method and apparatus that utilizes distance, elevation, and head pressure of a length of a river, stream, and/or any other water channel.
- The present invention is a hydroelectric power generating method and/or apparatus. The generating apparatus is configured to pass a portion of a flow of water through an input pipe and a feedline configured with funneling of the piping to increase the pressure of the water to a pressure sufficient to turn a turbine of a turbine generator combination. The turbine is interconnected with and drives a generator that outputs electrical power. The water that flows through the turbine is then returned to the stream or river from which it came.
- The hydroelectric power generating apparatus can include an inlet pipe with plural apertures along the length of the inlet pipe. The inlet pipe can be configured in the form of plural inlet pipes as desired to accommodate a predetermined amount of water. The inlet pipe is preferably positioned substantially perpendicular to the direction of the flow of water. The inlet pipe is interconnected to a feedline that includes pipe couplings, a source pipe and an input pipe. The input pipe is interconnected to the pipe couplings with a funnel shaped end.
- The input pipe extends for a predetermined distance and is interconnected to a turbine generator combination. Water passes through the turbine generator combination and through an outlet pipe. The water then passes through a pressure dissipation device (tank) that causes a reduction in the pressure of the water. The pressure dissipation tank relieves pressure so that the water can be released back into the stream or river without having a negative effect on the oxygen levels in the water. The water then passes through a drain pipe and is released back into the stream or river via one or more outlet pipes. As with the inlet pipe, the outlet pipe is configured with plural apertures along the length of the outlet pipe. The water being released back into the stream or river can have the same values and natural flow as the original values before entry into the generating apparatus. Alternately, the released water could be reintroduced into another generating apparatus that is in series, using more inlets to supplement the next generating apparatus.
- The piping of the power generating apparatus can be located on the bed of the stream or river, or can be provided on ground or buried in ground near the side of the stream or river. If the piping is located in the bed of the stream or river, it is preferably located on a gravel foundation such that it is not substantially damaged in extreme flood events. The turbine generator combination can be configured as desired. For example, the turbine could be a shaft propeller type turbine and the generator could be configured to generate a terminal voltage of between around eleven and thirty kilovolts. The generator output could then be connected to a transformer that could step up the voltage to around two hundred and twenty kilovolts, or to a predetermined desired output voltage.
- The hydroelectric power generating apparatus can be varied with, as described above, with plural inlet pipes and plural outlet pipes. The power generating apparatus can also include flow control valves, a by-pass pipe, a y-strainer, and y-strainer valves. The power generating apparatus can be interconnected with in series with other power generating apparatuses. Various aspects of maintenance of the power generating apparatus can be accomplished through the use of the flow control valves and the by-pass pipe that enable maintenance to be performed. The y-strainer is placed inline above the generator to catch debris and sediment. This can be cleaned on a scheduled maintenance program to keep the power generating apparatus running smoothly. Variations can be made regarding the materials and configurations of the various components of the generating apparatus. The piping sizes can be reduced to reach a desired pressure sufficient to turn the turbine of the turbine generation combination. The piping can be flanged on both sides and bolted together using engineering materials and torque specifications. Deliver ductwork can be buried as it reaches the shore to significantly reduce visual impacts.
- A hydroelectric power generating method provides at least one inlet pipe perpendicular to a flow of water in a stream or river, the at least one inlet pipe having a length and plural apertures along the length of the at least one inlet pipe; interconnects a feedline and a turbine generator combination with the at least one inlet pipe; interconnects at least one outlet pipe with the feedline and the turbine generator combination, the at least one outlet pipe having an elevation lower than the inlet pipe; passes a flow of water through the at least one inlet pipe, the feedline, the turbine generator combination, and the at least one outlet pipe; and generates electricity from the flow of water passing through the turbine generator combination.

Shown in the drawings and described herein below in detail are preferred embodiments of the invention. It is to be understood, however, that the present disclosure is an exemplification of the principles of the invention and does not limit the invention to the illustrated embodiments.
- Referring now to the drawings,
FIGS. 1 and 2 show a hydroelectricpower generating apparatus 100 according to the invention. Thepower generating apparatus 100 is configured to pass a portion of a flow ofwater 110 through aninput pipe 120, afeedline 122 configured with funneling of the piping to increase the pressure of the water to a pressure sufficient to turn a turbine of aturbine generator combination 140. The turbine is interconnected with and drives a generator that outputs electrical power. The water that flows through the turbine is then returned to the stream or river from which it came. - As illustrated, the hydroelectric
power generating apparatus 100 includes aninlet pipe 120 with plural apertures along the length of theinlet pipe 120. Theinlet pipe 120 can be configured in the form of plural inlet pipes as desired to accommodate a predetermined amount of water. Theinlet pipe 120 is preferably positioned substantially perpendicular to the direction of the flow ofwater 110. The inlet pipe is interconnected to afeedline 122 that includespipe couplings 124, asource pipe 120 and aninput pipe 128. The input pipe is interconnected to thepipe couplings 124 with a funnel shapedend 126. - The
input pipe 128 extends for a predetermined distance and is interconnected to aturbine generator combination 140. Water passes through theturbine generator combination 140 and through anoutlet pipe 142. The water then passes through a pressure dissipation device (tank) 150 that causes a reduction in the pressure of the water. Thepressure dissipation tank 150 relieves pressure so that the water can be released back into the stream or river without having a negative effect on the oxygen levels in the water. The water then passes through adrain pipe 152 and is released back into the stream or river via one ormore outlet pipes 160. As with theinlet pipe 120, theoutlet pipe 142 is configured with plural apertures along the length of theoutlet pipe 160. The water being released back into the stream or river can have the same values and natural flow as the original values before entry into the generatingapparatus 100. Alternately, the released water could be reintroduced into another generatingapparatus 100 that is in series, using more inlets to supplement thenext generating apparatus 100. - The piping of the
power generating apparatus 100 can be located on the bed of the stream or river, or can be provided on ground or buried in ground near the side of the stream or river. If the piping is located in the bed of the stream or river, it is preferably located on a gravel foundation such that it is not substantially damaged in extreme flood events. Theturbine generator combination 140 can be configured as desired. For example, the turbine could be a shaft propeller type turbine and the generator could be configured to generate a terminal voltage of between around eleven and thirty kilovolts. The generator output could then be connected to a transformer that could step up the voltage to around two hundred and twenty kilovolts, or to a predetermined desired output voltage. - Referring to
FIG. 3 , the hydroelectricpower generating apparatus 200 can be varied with, as described above, withplural inlet pipes 220 andplural outlet pipes 260. Thepower generating apparatus 200 shown inFIG. 3 also includesflow control valves pass pipe 238, a y-strainer 222, and y-strainer valves 224. Thispower generating apparatus 200 can be interconnected with in series with other hydroelectricpower generating apparatuses 300. Various aspects of maintenance of the hydroelectricpower generating apparatus 200 can be accomplished through the use of theflow control valves pass pipe 238 flowing intopressure dissipation tank 250 that enable maintenance to be performed. The y-strainer 222 is placed inline above the generator to catch debris and sediment. This can be cleaned on a scheduled maintenance program to keep thepower generating apparatus 200 running smoothly. Variations can be made regarding the materials and configurations of the various components of the hydroelectricpower generating apparatus 200. The piping sizes can be reduced to reach a desired pressure sufficient to turn the turbine of theturbine generation combination 240. The piping can be flanged on both sides and bolted together using engineering materials and torque specifications. Delivery ductwork can be buried as it reaches the shore to significantly reduce visual impacts. The configuration of the inlets, outlets, and other components of the generatingapparatus 200 can be varied as desired. - The hydroelectric
power generating apparatus 200 uses volume and head pressure to turn and drive theturbine generator combination 240. Thepower generating apparatus 200 utilizes pipe that is reduced to reach a specific pressure and volume to obtain a predetermined pressure. While thepower generating apparatus 200 is one configuration example of the hydroelectric power generating apparatus according to the present invention, it is the full intent of the applicant that a power generating apparatus according to the present invention may be varied in any number of suitable configurations as desired. For example, the piping system could be put directly in a particular water channel, material for the piping could be varied as desired to inhibit or preclude environmental damage, varying number of inlets could be provided as desired, etc. - Placement of the hydroelectric
power generating apparatus 200 is preferably along the length of a stream or river where that passes through a predetermined elevation distance. For example, consider a stream or river with an elevation of approximately four hundred feet from a beginning point to an ending point along a distance of five thousand feet. A forty-eight inch diameter pipe could be used at the beginning and run for approximately two thousand feet, while the pipe is necked down to a predetermined size. With an elevation of four hundred feet, a pressure of about one hundred and seventy-five pounds per square inch could be obtained which would be sufficient pressure and volume to turn the turbine of theturbine generator combination 240. - Generating electricity using a hydroelectric
power generating apparatus 200 according to the invention provides a variety of advantages over conventional power generation techniques. By using only a portion of the water flow of a stream or river, use of multiple generatingapparatuses 200 placed at multiple locations along the length of a stream or river would simplify distribution and make demand more adjustable. Output from generating apparatuses could be used by big electric companies or, on a smaller level, by farmers and ranchers(for irrigation, etc., using either the head pressure or the turbine generation for running motors for the pumps. Small towns and cities could use the same methods with their water systems. - A hydroelectric power generating method provides one or more inlet pipes perpendicular to a flow of water in a stream or river. The inlet pipes have a length and plural apertures along the length of the inlet pipes. A feedline and a turbine generator combination are interconnected with the inlet pipes. One or more outlet pipes are interconnected with the feedline and the turbine generator combination. The outlet pipes have an elevation lower than the inlet pipe. A flow of water passes through the inlet pipes, the feedline, the turbine generator combination, and the outlet pipes, and generates electricity from the flow of water passing through the turbine generator combination. The hydroelectric power generating method also provides a pressure dissipation device that causes a reduction in the pressure of the water so that the water can be released back into the stream or river without having a negative effect on oxygen levels in the water.
