Abstract
A system and process for generating hydroelectric power within a body of water relying on the pressure head existing between two depths of the water. A vertically arranged conduit or penstock has an upper water intake and is in fluid communication with a reservoir situated at a lower depth. In a first cycle, water flow is established in the conduit or penstock between the water intake and lower reservoir when the reservoir is substantially full of air. A turbine housing is mounted adjacent the reservoir at a lower depth than the water intake and houses an electric turbine generator having blades mounted within the conduit or penstock to be driven by the flow of water to generate electricity. As water is introduced into the reservoir, air is exhausted out an air exhaust tube to a point above the surface of the body of water. After the reservoir is generally full of water valves are provided to cease the flow of water through the water intake and flow of air out the exhaust tube. An air pump thereafter introduces air into the reservoir to force water out of a reservoir water outlet port. The generating cycle is then repeated.
Description
- 1. Field of the Invention
- This invention relates in general to hydroelectricity and, more particularly, to a system and method for generating hydroelectric power in an efficient and environmentally clean manner.
- 2. Summary of the Prior Art
- In the prior art there have been numerous attempts to develop satisfactory techniques of efficiently generating electricity without pollution. Many prior systems have relied on energy inherent in nature, including the forces found in atmospheric winds and the of energy created by water flowing in rivers, over dams, and the pressure differentials present at the depths of bodies of water, such as in oceans, seas, bays, lakes, and the like. It is the objective in the prior art when attempting to rely on nature to provide the energy for the generation of electricity to do for reasons of economy, efficiency, and minimization of pollution, such as created by environmentally harmful fossil fuels and the potential problems associated with nuclear energy.
- In some prior art power generators, attempts have been made to employ the energy potential present in a head of water to generate hydroelectric power. In general, prior designs relying on pressure differential have not attained an optimum level of power generation as is desired in the industry. An example of a known technique for generating electric power relying on the energy potential of a pressure head in a body of water is disclosed in U.S. Pat. No. 4,321,475 issued Mar. 23, 1982 to Grub. The technique taught in Grub is subject to certain inefficiencies involving the vertical lifting of water and other design flaws. It is desirable, therefore, to provide an improved system and method for generating hydroelectric power that is relatively efficient and economical to maintain and operate.
- It is accordingly an objective of this invention to provide an improved and economical system and method for the generation of hydroelectric power. The system and process herein disclosed extracts energy from the pressure head present in a body of water, such as, for example, from an ocean, sea, bay, lake and the like. Although the invention can operate at any depth within body of water, depths of greater than 100 feet are preferred for best efficiencies.
- The system herein includes an upper submerged inlet port of a vertical conduit or penstock that is selectively in fluid communication with a sealed air filled reservoir positioned at a lower depth of the body of water. The blades of a turbine generator of known design are positioned within the penstock or conduit in series with the reservoir so that energy produced by a head of water drives the blades of the electric generator at great velocity for generating hydroelectric power. The flow of water is created by opening fluid control means to the reservoir at the same time fluid control means in the intake port is opened. The water flow continues to drive the turbine generator until such time as the reservoir is generally filled with water as the level of water reaches a selected point. The air within the reservoir is pushed out through an air outlet tube during water flow process. Air pump means in fluid communication with the reservoir acts to drive out the collected water through a reservoir egress after the system fluid control means that opened during generation cycle are closed. After evacuation of the water from the reservoir, the system is ready for another cycle. To increase power output, multiple reservoir chambers and conduits are used to provide more continuing operation of the system
-
FIG. 1 is a side elevational view of the system for generating hydroelectric power of the invention; -
FIG. 2 is a side elevational view of the invention for generating hydroelectricity employing a plurality of water flows. - Referring to
FIG. 1 , there is illustrated a first embodiment of the system for generating hydroelectric power in accordance with the invention, generally designated byreference numeral 2. Thesystem 2 uses components submerged in a body of water 4, such as an ocean, lake, sea, bay and the like, that extract the energy derived from the pressure head present at a predetermined depth. Anupper platform 6 is mounted above the water surface 4′ at a selected height. Theplatform 6 can comprise any known platform design that employs support columns (not shown) extending to the floor of the body 4 of water. Other methods of supporting theplatform 6 may be employed, whether structural or using flotation means. Theplatform 6 carries a plurality of downward extendingcable attachments 8, such as, for example, four or more in number. Other support devices such as struts and the like may be used in place of thecables 8. Thecables 8 support an enlargedwater intake 8′ at a position submerged beneath the surface 4′ of the body of water 4. A sealedreservoir 10 is supported on thebottom 12 of the body 4 of water by legs orpillars 14. Thereservoir 10 is sealed to retain air within itsinterior chamber 16. As will be described later herein, thechamber 16 is designed to be substantially filled with water during the power generating cycle ofsystem 2 after which the water is removed fromchamber 16 by air pressure to complete the operating cycles of thesystem 2. The selected capacity ofreservoir 10 is dependent on numerous physical factors, including, but not limited to the desired output and efficiency ofsystem 2. For example, thereservoir 10 may have capacity of twenty million gallons, although a smaller or larger capacity may be employed dependent on desired results. - A generally vertical conduit or
penstock 20 is selectively in fluid communication with aport 22 provided in the lower portion ofinlet water intake 8′. The conduit orpenstock 20 may comprise either a flexible or rigid structure. An electrically controlledvalve 24 is operatively mounted inport 22 to control the flow of water into the conduit orpenstock 20. A sealedturbine housing 30 having an air filled interior is mounted adjacent thereservoir 10 and receives a portion of the downward extending conduit orpenstock 20 with suitable sealing between the interior ofhousing 30 and the surrounding water. Anelectric turbine generator 32 of conventional design is suitably mounted exteriorly of the portion of conduit orpenstock 20 within theturbine housing 30. Theelectric turbine 32 generates electric power through the rotation ofturbine blades 32′ that are mounted within the conduit orpenstock 20 and drive the generator in a known manner. As should be appreciated, multiple electric turbine generators (not shown) may alternatively be positioned withinturbine housing 30 and each may have turbine blades within the conduit orpenstock 20 to generate electricity in concert with each other. The conduit orpenstock 20 passes in and out of theturbine housing 30 and is in selective fluid communication with anintake port 34 ofreservoir 10. Aflow valve 36 is provided in operative relationship tointake port 34 to selectively allow flow through conduit orpenstock 20 and drive theturbine generator 32. Suitable electric lines (not shown) are connected toturbine generator 32 and distribute the generated electricity to a distribution system (not shown) situated at suitable exterior location fromsystem 2. - The
reservoir 10 is intended to be positioned at a depth of about 300-500 feet beneath thewater intake 8′ so as to generate a large flow of water through conduit orpenstock 20 created by the significant pressure differential existing between the air filledchamber 16 and thewater intake 8′ as result of the pressure head of water existing above thereservoir 30. The water enteringintake 8′ falls from a great height to the air filled reservoir at a large rate of flow through the conduit orpenstock 20. It is within the scope of the invention to situate thereservoir 10 above or below the range of 300-500 feet dependent on the body of water and the desired efficiency and power to be generated. From the foregoing it should be apparent that a flow of water is attained through conduit orpenstock 20 whenvalves air inlet tube 50 that may be carried by platform 4 is operatively connected at its upper end above the surface 4′of the body of water to anair pressure pump 52 that is mounted on platform 4. Theair pressure pump 52 can be a conventional device driven bywind mill vanes 52 a. Alternatively, theair pump 52 may be driven by solar energy, a fossil fuel, or by using a portion of the electricity generated byturbine generator 32 ofsystem 2 through an electric connection line (not shown). Theair inlet tube 50 extends downward and is coupled in fluid communication with thechamber 16 ofreservoir 10 by aninlet port 58 having a oneway valve 58′. Anair outlet tube 60 is connected to anair outlet port 62 ofreservoir 10 and extends upward in connected relationship toplatform 6 to anair outlet 64 to exhaust air fromreservoir 10 during the electricity generating cycle. Avalve 66 is mounted inreservoir port 62 which opens in concert to the opening ofvalves door 70 which opens and closes awater outlet 72 is mounted onreservoir 10 foremptying chamber 16 after it has been generally filled with water following the electricity generating cycle, as determined bylevel detector 17. The slidingdoor 70 alternatively can comprise a conventional valve if desired. Aconventional computer device 80 is mounted on platform 4 and is electrically connected to electrically operated tovalves door 70, the controls ofair pump 52 and tolevel detector 17 to open and close the valves and operate theair pump 52 in accordance with the sequence of operation of the invention. - In operation, during a non-generating cycle with the
reservoir 10 containing water after an electricity generating cycle, theair pump 52 is actuated bycomputer 80 and pumps air at a predetermined pressure throughair inlet tube 50 and into thechamber 16. At the sametime sliding door 70 opensport 72 whilevalves pump 52 forces the water out of thechamber 16 throughwater outlet 72. Once the reservoir is substantially filled with air, theport 72 is closed by slidingdoor 70 to seal thechamber 16 while theair pump 52 ceases operation withvalve 58′ closing. It is not necessary, however, to force all of the water out of thereservoir 10. Thevalves water intake 8′ and downward through conduit orpenstock 20. The water flow through the conduit orpenstock 20 enters theturbine housing 30 to drive theturbine blades 32′ thereby generating electricity. Subsequently, the water falls intochamber 16 forcing air out throughair outlet tube 60. Theair outlet tube 60 may be tapered to increase the air flow rate through the tube so that the stream of air fromair outlet 64 can be used to rotate thewindmill vanes 52′ to charge theair pump 52 in known manner. Once thereservoir 10 is substantially filled with water as determined bywater level detector 17, thevalves reservoir 10 is repeated. It should be clear that thesystem 2 provides successive cycles of power generation and removal of water from thechamber 16 to complete the process of generation. - Referring now to
FIG. 2 , there is illustrated a second embodiment of the invention, generally designated byreference numeral 2 a. For a greater and more continuous power output, thesystem 2 a establishes a plurality of water flows to generate electricity in two successive cycles, such as two separate flows as shown inFIG. 2 . If desired, it is within the scope of the invention to run the redundant components ofFIG. 2 generally simultaneously if desired. It should further be clear thatsystem 2 a could be modified further by employing more than two conduits establishing more than two water flows to generate electricity. - In
FIG. 2 , an upper platform 6 a is elevated above the water surface 4′ at a selected height. Cables 8 a support a pair of enlarged water intakes 8 a′ beneath the surface 4′ of the body of water. A sealedreservoir 10 a is mounted on the bottom 12 of the body of water by legs or pillars 14 a. Thereservoir 10 a is sealed to selectively contain air within a pair ofinterior chambers reservoir 10 a to create thechambers chambers system 2 a after which the water is removed from eitherchamber system 2 a. As described in connection with the description of the first embodiment ofFIG. 1 , the selected capacity ofreservoir 10 is dependent on numerous physical factors, including, but not limited to, the desired output and efficiency ofsystem 2. It is within the scope of the invention to employ duplicate reservoirs (not shown) rather than the dividedreservoir 10 a as shown inFIG. 2 . - A pair of conduits or penstocks 20 a are selectively in fluid communication with separate ports 22 a which are provided in the lower portion of the pair of inlet water intakes 8 a′. Electrically controlled valves 24 a are respectively mounted in ports 22 a to control the separate flows of water into the respective conduits or penstocks 20 a. A sealed
turbine housing 30 a is mounted adjacent thereservoir 10 a and receives a portion of both conduits or penstocks 20 a with suitable sealing between the interior ofhousing 30 a and the surrounding water. Anelectric turbine 32 of conventional design for generating electricity is operative mounted with inhousing 30 a and hasturbine blades 32 a′ respectively mounted for rotation within each of the conduits or penstocks 20 a in a known manner. It is within the scope of the invention to employ multiple turbine electric generators (not shown) in association with each conduit or penstock 20 a, if desired. The pair of conduits or penstocks 20 a pass in and out of theturbine housing 30 a and are in selective fluid communication withseparate intake ports 34 a in communication withchambers reservoir 10 a. A pair of electrically controlledflow valves 36 a are provided in operative relationship tointake ports 34 a to selectively create a flow of water through either of the pair of conduits or penstocks 20 a and drive theturbine generator 32, whereby the separate flows of water effect successive cycles of the generation of electricity. The generation of electricity of thesystem 2 a is based on the same principle as thesystem 2 ofFIG. 1 . The rapid flow of water through conduits or penstocks 20 a is derived from the pressure differential existing between the separate air filledchambers 16 a,b and the water intakes 8 a′ due to the head of water existing above thereservoir 10 a. From the foregoing it should be apparent that the two successive separate flows of water through conduits or penstocks 20 a occur whenvalves 24 a and 36 a which are respectively operatively connected to the separate conduits are opened. - A pair of
air inlet tubes 50 a are each operatively connected at their upper end above the surface of the water to air pressure pumps 52 a, 52 b that are mounted on platform 4 a. The air pressure pumps 52 a, 52 b are of same type as described with reference to the embodiment ofFIG. 1 . Theair inlet tubes 50 a extend downward and are each coupled in fluid communication with arespective chamber reservoir 10 a through respectiveair inlet ports 58 a. Theinlet ports 58 a each having an electrically operated, oneway valve 58 a′. A pair of reservoirair outlet tubes 60 a are respectively connected toair outlet ports 62 a of one ofchambers outlet tubes 50 a extend upward in connected relationship to platform 6 a and terminate with anair outlet 64 a to exhaust air from thechambers reservoir 10 a to which they are connected during the successive generating cycles.Valves 66 a are respectively mounted inreservoir outlet ports 64 a which open in concert to the opening ofvalves 24 a and 36 a. A pair of electrically powered doors 70 s opening and closing a water outlet 72 a to eachchamber reservoir 10 a. Thedoors 70 are used to empty achamber conventional computer device 80 is electrically connected to electrically operatedvalves door 70 to open and close the respective devices in conjunction with the successive duplicate power generating cycles ofsystem 2 a. - In operation of the system of
FIGS. 2 a, during the alternate non-generating cycles with either of thechambers reservoir 10 a being generally full of water after the respective generating cycles, one of the air pumps 50 a, 50 b is actuated bycomputer 80 and pumps air at predetermined pressure throughair inlet tube 50 a and into the water filledchamber 16 a orchamber 16 b. At the same time the particular sliding door 70 a communicating with the water filled chamber opens outlet 72 awhile valves air pump 52 b forces the water out of therespective chamber 16 a orchamber 16 b through either of the water outlets 72 a. Once thatparticular chamber 16 a orchamber 16 b is substantially filled with air, the sliding door 70 a moves to close outlet 72 a and seal the associatedchamber 16 a orchamber 16 b while at the same time the operatingair pump 52 a or pump 52 b ceases operation with avalve 58 a′ closing. Thevalves chamber 16 a orchamber 16 b are thereupon opened at generally the same time. Water rapidly falls into water intake 8 a′ and downward through one of conduits or penstocks 20 a associated with the emptiedchamber chamber 16 a orchamber 16 b, theblades 32 a′ within theturbine housing 30 are rotated to driveelectric generator 32. Subsequently, the water falls into eitherchamber air outlet tube 60 a connected tochamber 16 a orchamber 16 b that is being filled with water. Once thechamber 16 a orchamber 16 b is generally filled with water as determined bywater level detector 17 a or 17 b, the associatedvalves reservoir 10 is repeated. It should be clear that thesystem 2 provides duplicate successive cycles of power generation and removal of water from arespective chamber 16 a orchamber 16 b.
