It should be understood by one of ordinary skill in the art that the exemplary embodiments of the present disclosure can be applied to other types of hydrokinetic devices and generators, and even to wind generators.
  • an exemplary auger turbine 10 is shown.
  • the auger 10 is preferably formed of a lightweight material, such as rotationally molded plastics or molded carbon fiber. It will be appreciated that any suitable material may be used. Reinforcing structures, such as metal ribbing, may be included internally in the turbine blade. In order to aid buoyancy, the auger may be hollow, or can include air pockets or other buoyancy aids.
  • the helical auger turbine 10 comprises a helical turbine blade 1 1 provided with a flange 12 at the edge of the blade. The flange 12 is arranged generally perpendicularly to the helical turbine blade 1 1.
  • the edges of the flange 12 are smoothly curved, and the turbine blade may also have a gently curved center.
  • the flange is approximately equal to 25% ⁇ 10% of the outside diameter of the flange.
  • the flange 12 can be 2'-6' in width, preferably 3'-5'.
  • a tapered terminal section 13 is provided at each end of the turbine blade 1 1 .
  • the diameter of the turbine blade 1 1 is gradually and smoothly reduced so that it is tapered into a central shaft 14.
  • No flange is provided at the edge of the tapered terminal section 13, and in a preferred arrangement, ends of the flange 12 leading into the tapered sections 13 are reduced in diameter, to prevent the formation of a sharp edge to the flange that could damage marine life.
  • the tapered sections 13 help to reduce damage to marine life that may come into contact with the auger 10 from either direction, by providing a tapered lead in.
  • a tapered shape is also more tolerant of water- borne or floating debris, and is less likely to suffer damage therefrom.
  • the diameter of the turbine blade 1 1 can be reduced in the tapered sections 13 from, for example, 16' to 4' within 140 - 180 degrees of rotation of the helix, for example within 165 degrees of rotation.
  • the helical turbine blade 1 1 preferably has a 45° pitch, although it will be appreciated that any suitable pitch may be used.
  • the turbine can be supplied in sections of 45° arc or 90° arc that can be assembled together and locked onto the central shaft 14, producing a smooth helical spiral. This permits assembly of the auger 10 on site to suit the intended application and desired size of the energy capturing zone. Typically, a completed auger 10 will have 360° of arc, but of course more or fewer turns of the helix may be used in different applications by adding fewer or more sections.
  • the auger 10 is designed to rotate relatively slowly with the tidal flow, and the large size and smoothly curved edges allow marine life such as fish to safely move around the blade without becoming trapped or injured.
  • the flange 12 allows the auger to capture water flows coming from various directions to help turn the auger 10 even with a slow flow or if the How comes from a non-ideal direction.
  • the central shaft 14 of the auger 10 is hollow, through which an axle shaft can extend. With a 16' diameter auger, the shaft 14 can have a diameter of 18" although of course any suitable size can be employed.
  • the axle shaft can be connected at either end to one or more nose cones 16, and allows the auger 10 to rotate on bearings.
  • the nose cones 16 can be connected by mooring cables 18 to anchors (not shown) that can anchor the auger 10 to the seabed or to joints tethered to an oil rig leg or other securing structure.
  • the nose cones 16 can be provided adjacent to the tapered terminal sections 13 where the diameter of the auger 10 is reduced, in order to prevent pinch points between the auger and nose cone 16.
  • the augers 10 can be anchored in any suitable manner (such as by cables, tether, fasteners, etc.) to any suitable support structure.
  • the auger can be secured to the legs of an oil rig 20, as shown in Fig. 6.
  • a plurality of augers can be distributed in any suitable manner on the rig 20.
  • the augers can be submerged at a sufficient depth in a body of water so that they are away from floating debris, trees, logs, ice, etc.
  • the augers 10 can be tethered in place at depths of approximately 8'-10' below the lowest tides, to avoid floating debris.
  • the augers 10 can be oriented generally horizontally, and can be oriented with their central shaft 14 approximately parallel to the tidal or river flow for maximum energy capture. l " he augers can be adapted to allow for changes in the vertical level of the water in which they are submerged, and can capture tidal flow without horizontal orientation as other tidal generators must do to always be in the same direction with respect to the water flow. To that end, each auger 10 can include horizontal stabilizers with computer controlled ailerons to hold the auger horizontal and parallel to the tidal flow.
  • the rotation of the augers can be transmitted to power a hydraulic pump, which can generate high pressure oil that can be used for any suitable purpose.
  • the system can be adapted so that water flow in cither direction can operate the auger and can store energy in an accumulator, as shown particularly in Figs. 7-9.
  • water flow will turn the auger 10.
  • the rotation of the auger can be transmitted to operate the pump, which, in turn, will store hydraulic energy in the accumulator.
  • the stored energy in the accumulator can be released to continue the steady operation of the electric generator.
  • the accumulator can function as follows. During water flow, rotation of the augers 10 can be transmitted, such as by gears, to operate a high pressure hydraulic pump such as a stationary pressure compensated variable volume hydraulic motor/pump 30 that can be located in the stationary tethered nose cone assembly 16 with all necessary radial and thrust bearings also housed in the nose cone.
  • a planetary gearing system 31 can be provided inside the nose cone 16 or another part of the auger 10 to increase the relatively low speed of revolutions per minute of the auger 10 to a level of RPM that can be efficiently used to power the pump 30.
  • the pump 30 can be in fluid communication with an air-fluid accumulator 32, and can be bi-directional to maintain a constant high pressure of hydraulic oil at all speeds irrespective of whether it is accelerating or decelerating or reversing during the cyclic tidal flow. This can be accomplished by a series of criss-cross check valves 34 on a hydraulic circuit 36.
  • a vented elevated hydraulic fluid storage tank 38 can be supplied to store oil or other hydraulic fluid. It is preferred that all hydraulic fluid is water based and non-flammable so that any leakages in the system due to debris impact will not create a danger or an oil spill.
  • a system controller causes the criss-cross check valves 34 to be closed so that hydraulic fluid flows from the air-fluid accumulator 32 through fixed displacement hydraulic piston motors 40 without flowing through the pump 30. The high pressure in the air-oil accumulator 32 causes fluid to be propelled through the hydraulic circuit 36.
  • the hydraulic piston motors 40 can drive an electric generator 42 via a shaft 44.
  • a suitable hydraulically driven electric generator may be similar to those currently used on emergency vehicles such as fire trucks.
  • the accumulators 32 release their stored high pressure fluid to drive the electrical generators 42 at their steady output requirements. Fluid then circulates further through the hydraulic circuit 36 to the oil/fluid storage tank 38.
  • the output volume of the pump 30 can be set larger than the volume of steady flow required by the generator 42.
  • the system controller opens some of the criss-cross valves 34 to open the hydraulic circuit 36 through the pump 30 that is driven by the auger 10, with the hydraulic fluid flowing in one direction.
  • the excess volume of fluid over the generator's flow requirement automatically flows to the air-fluid accumulator 32 for energy storage, and builds up the pressure inside the accumulator 32.
  • Hydraulic fluid may be released from the storage tank 38 via a one-way valve, to ensure that a sufficient volume of fluid is always present in the circuit 36.
  • Multiple accumulators 32 of various sizes can be connected in parallel, enabling adequate energy storage.
  • the system controller detects when maximum flow is reached again.
  • the criss-cross valves 34 are operated so that the flow in hydraulic circuit 36 through the pump 30 is reversed and can thus be driven by the auger 10 rotating with the reversed tidal flow, while the flow through the hydraulic piston motors 40 remains in the same direction.
  • the pump 30 can be mono-directional and can pump consistent and constant pressure hydraulic fluid in one direction only to the accumulators 32. In river applications, therefore, criss-cross check valves 34 are not required.
  • Each location thus requires a study to determine the maximum and minimum tidal flow at peak tidal motion, or the size of the river current, in order that the appropriate number, arrangement and sizes of accumulators are used.
  • ⁇ computer system can control the accumulators and generators to provide the greatest efficiency in energy generation.
  • the tides are have a mean diurnal range of 15-28 feet and change every six hours.
  • ⁇ 16 ft diameter auger of carbon fiber material can be submerged into the flow below the ice pack which forms in the winter.
  • the augers 10 can be attached to oil platforms in the inlet. Most platforms have 3 or 4 legs, and thus if 4 augers are attached to each leg this enables 12-16 augers to be run simultaneously.
  • the auger 10 can turn on a stationary hollow shaft on sealed bearings to turn a gear box and through a planetary gear system, similar gearing that drives the propeller at the speed of a jet prop airplane engine. This can turn a high pressure hydraulic pump.
  • this system can pressure up the air-oil accumulator 22. As the flow slows for roughly one hour, the pressured storage of hydraulic oil can continue to turn the hydraulic turbine electric generator.
  • the system is bi-directional, accomplished with crisscross check valves, so that power is stored to the accumulator 22 in either water flow direction.
  • the system can be cable tethered parallel to the tidal flow for maximum energy capture. In deeper water, it is possible to attach a number of the units 10 around the platform 20, arranged up each of the platform legs, evenly staked vertically one over the other.
  • the gear-driven hydraulic pumps can be located in the nose cone 16 closest to the platform 20.
  • the oil lines are tethered to the platform legs and extend up to the accumulator 22 on the upper platform deck. This will protect them from damage by debris, because the units can be tethered a minimum of 10-15 ft under the surface of the water. Actual electricity generation can be up on the platform 20, out of the ocean water.
  • the tethering system allows for a vertical water level change with the tide.
  • the horizontal stabilizers can have computer control ailerons similar to airplane wings to hold the augers horizontally, and parallel to the tidal flow.
  • the augers 10 can be placed on bridge pilings that are cither positioned in tidal flow areas or in rivers.
  • the augers 10 can be used on decommissioned oil rigs to provide power generation that can be transmitted onshore via cables. This can prolong the useful life of oil platforms even afler drilling is no longer economically feasible.
  • floating pontoon bridges can be used to tether the augers 10. Hach installation (bridge, oil platform, pontoon bridge, etc) can in addition have one or more wind generators mounted above the water to provide additional generation capacity to the installation.
