Detailed description of the present invention
Hydro Kinetic Turbine
The invention is now described in further detail with reference to the accompanying drawings.
The present invention is subject to multiple variations, applications, alterations and modifications. The drawings shown and described herein do not limit or imply the final or finished version or versions of the present invention. Whilst the underwritten description of the invention enables reconstruction of the present invention the existence of variations, permutations and equivalents of the specific embodiments, methods and examples thereof are accepted. The descriptions and diagrams contained herein of the present invention therefore do not limit but rather enlarge the scope and spirit of the present invention.
The present invention is but not limited to a submersible or floating linear motion hydro kinetic turbine for producing energy from natural or other flows and currents of liquid bodies.
Referring to the present invention in more detail figures 1, 2 and 3 show a hydro kinetic turbine 10 supported on a water surface 30 by floatation and ballast tanks 36. The water surface 30 may be, but not limited to, a river, estuary or sea. Multiple bearings 34 incorporated in floatation and ballast tanks 36 support a plurality of lower shafts 18 upon which mount entry conveyor drive gear 24 and exit conveyor drive gear 26. A frame extends at an angle of 20 deg to 60 deg upwards and forwards from floatation and ballast tanks 36 to carry bearings 34 supporting shaft 18 which carries upper conveyor drive gear 22.
A plurality of blades 12 with a convex shape facing away from the current 28 and sides enclosed at an angle are connected to conveyors 20 by means of a plurality of hinged device 14. A locking device 16 is attached to conveyors 20 and to the blades 12. The conveyor 20 runs on upper conveyor drive gear 22, entry conveyor drive gear 24 and exit conveyor drive gear 26.
Materials used in the construction of the present invention shown in figures 1, 2, 3, 4 and 5 may comprise, but not limited to: the floatation and ballast tank 36, shafts 18, upper conveyor drive gear 22, entry conveyor drive gear 24 and exit conveyor drive gear 26 and hinged device 14 may be constructed of stainless steel or composites and or other suitably rigid materials. The blades 12 may be stamped of aluminium or composites and or other suitably rigid materials. The conveyor 20 may be constructed of stainless steel roller chain, canvas, rubber or other suitably flexible, high tensile strength material. Bearings 34 may be roller or ball bearings, water lubricated wooden bearings or other suitable material.
The embodiment may be tethered by single or multiple tethers attached at one end to the floatation and ballast tank 36 and the opposing end to anchors. Anchors may be positioned on the water bed or embankments as desirable and within the geographic scope. Surface units of the present invention are tethered in such a way to allow the unit to rise and fall with the water surface 30. Submerged units may be tethered permanently at a predetermined depth but may be allowed to pivot on an axis 48 as described more fully hereunder. The nose 38 of the floatation and ballast tank 36 may be angled to direct further current 28 into the blades 12. Still referring to figures 1, 2 and 3 to describe the operation of the present invention the blades 12 traverse a looped circuit which could be described as 3 stages of linear motion around 3 axes, the axes being the upper conveyor drive gear 22, entry conveyor drive gear 24 and exit conveyor drive gear 26. The circuit commences as the conveyor 20 moves over upper conveyor drive gear 22 blades 12 fold over the upper conveyor drive gear 22 coming to vertical or near vertical alignment maintained by the locking device 16 and commence the power stroke in an approach to the water surface 30 with the conveyor 20 inclined at an angle to the water surface 30 between the upper conveyor drive gear 22 and the entry conveyor drive gear 24 allowing efficient entry to the water surface 30 and continuing to be pushed along by the current 28 in a linear motion towards the entry conveyor drive gear 24. On reaching the point of the entry conveyor drive gear the blades 12 are maintained in vertical alignment by the locking device 16 and become completely submerged below the water surface 30 being pushed by the full force of the current 28. The forces applied by the current 28 to the blades 12 now drive the blades in a horizontal plane towards the exit conveyor drive gear 26. The blades 12 are kept vertical against the forces of the current 28 by the locking device 16. Upon reaching the exit conveyor drive gear 26 the locking device 16 fully releases or releases tension applied to the blades 12 thus allowing the blades 12 to exit the current 28 efficiently and completing the power stroke. The blades 12 continue in a looped circuit around the exit conveyor drive gear 26. The blades 12 on reaching the upper point of the exit conveyor drive gear 26 lay flat and in an idle state on the conveyor 20 above the water surface 30. The conveyor 20 travels in a direction opposite to the current 28 pulling the blades 12 in an idle state the upper conveyor drive gear 22. On reaching the upper point of the upper conveyor drive gear 22 the blades 12 are said to have completed a full cycle of the looped circuit.
Power to rotate an electrical generator and or mechanical devices such as a water pump may be drawn from individual or a plurality of shafts 18 being driven rotationally by upper conveyor drive gear 22, entry conveyor drive gear 24 and exit conveyor drive gear 26.
A counter weight may be incorporated into the upper end of the blades 12 situated centrally between the hinged device 14. The counter weight enables smoother travel of the blades 12 over the upper conveyor drive gear 22 and exit conveyor drive gear 26. A shock absorber may in addition be incorporated into the lower end of the blades 12 to counter the effect of the gravitational forces on the blades 12 when traversing the axis of the upper conveyor drive gear 22.
As illustrated in figure 6 the locking device 16 may alternatively, but not limited to, comprise a fixed locking rail 52 running from a point below the upper conveyor drive gear 22, inclined to follow the plane of the conveyor 20 to below the entry conveyor drive gear 24 where after the locking rail 52 extends in a horizontal plane terminating at a point below the exit conveyor drive gear 26. A roller or castor wheel 54 is attached to a lower section of the blades 12 where the roller or castor wheel 54 runs along the length of the fixed locking rail 52 maintaining the blades 12 in the required plane during the power stroke.
In further detail referring to figures 4 and 5 these show an alternate version of the present invention where the hydro kinetic turbine of the present invention may be used for generation of power from tidal flows. The turbine 46 may be, but not limited to, submerged by means of ballast applied to the floatation and ballast tanks 36 to a predetermined level at which the floatation and ballast tank 36 may be attached via a plurality of arms 50 to a pivot 48 connected to a single axis 40 embedded in, but not limited to, the estuary, sea or ocean bed. The turbine 46 rotates through 180 degrees on the pivot 48 to allow the turbine 46 to maintain the correct position in the current of the tidal flow to produce power. The pivot 48 may be powered by, but not limited to, an electrical device actuated by electronic apparatus at the turn of the tide. Referring to figure 4 the turbine 46 may be enclosed in an air tank 42 which excludes the blades 12 from being in the water current from the exit conveyor drive gear 26 to the upper conveyor drive gear 22 causing the blades 12 to encounter little resistance when not in the power stroke.
The present invention may in addition be adapted to but not limited to produce energy from wave action, waste and irrigation pipes, canals and any other instances where there is movement of a liquid body.
The advantages of the present invention include, but are not limited to, shallow water application and ability to produce significant power in shallow water by means of linear movement with the current. It has multiple applications being canals, waterfall, stream, river, estuary, tidal and wave. It may be adapted for installation into waste, irrigation and other pipes. It is environmentally friendly producing energy from natural flow without requirement for dams, weir, barrages or other diversions. The present invention may be manufactured of recycled and or other environmentally friendly material. It presents zero or limited hazard to aquatic life moving within its immediate proximity. The movement of the blades in a linear plane and speed approximately equal to the natural current result in near zero turbulence or eddy currents. The device can be built and installed into the water site in a relatively short space of time. Given the present invention's low capital cost per energy unit and without need for other infrastructure allows for a profitable alternative green energy solution.
