Abstract

This invention relates to a system for generating hydroelectricity from the tides. The current tidal hydroelectric technology being used is completely limited to suitable geographic areas. Tidal barrages and lagoons are expensive to construct, use very large quantities of raw materials and energy and have detrimental environmental impact. They only generate roughly 40% of the capacity of the electric generator. The invention is suitable to be used on any ocean current and or coastal tidal including within harbours. An advantage is that relatively small amounts of materials are used in its construction. It has little or no environmental impact and is much less expensive to construct and deploy.

Claims (23)

  1. Claims
    1 . A hydroelectric generating system comprises: a network of pipes, interconnected with at least a first valve which is operative to open one end of a pipe in the network, when the first end is at a relatively high pressure location, and a second valve opens a second end of a pipe in the network, the second end is in a relatively low pressure location; at least one hydroelectric turbine is located between the relatively high and relatively low pressure locations so that water flows from the relatively high pressure location to the relatively low pressure location, through the at least one hydroelectric turbine, thereby generating electricity; and a control system remote from the valves is operative to actuate at least one of the valves in accordance with a signal from a processor the signal being dependent upon tide times.
  2. 2. A hydroelectric generating system according to claim 1 wherein the at least one hydroelectric turbine is located on an oil rig platform.
  3. 3. A hydroelectric generating system according to claim 1 wherein the at least one hydroelectric turbine is located on a decommissioned ship.
  4. 4. A hydroelectric generating system according to claim wherein the at least one hydroelectric turbine is located on land.
  5. 5. A hydroelectric generating system according to any preceding claim wherein at least one pipe is laid on the sea bed.
  6. 6. A hydroelectric generating system according to any preceding claim wherein at least one pipe is buried under the sea bed.
  7. 7. A hydroelectric generating system according to any preceding claim wherein at least one pipe is floating on the sea or are semi submerged.
  8. 8. A hydroelectric generating system according to any preceding claim wherein at least one pipe is flexible to allow a pipe inlet and/or a pipe outlet to be moved to open towards or away from a rising or falling tide.
  9. 9. A hydroelectric generating system according to claim 8 wherein at least one pipe is moved using a robotic actuator.
  10. 10. A hydroelectric generating system according to any preceding claim wherein a means is provided to vary a manifold of a pipe inlet or outlet to accommodate fluctuations in turbulence.
  11. 11. A hydroelectric generating system according to any preceding claim wherein one or more filters prevent fish and other debris from entering a pipe and damaging a turbine.
  12. 12. A hydroelectric generating system according to any preceding claim wherein at least one pipe is formed from a recycled plastics material.
  13. 13. A hydroelectric generating system according to claim 12 wherein the diameter of at least two of the pipes is different one from another.
  14. 14. A hydroelectric generating system according to any preceding claim wherein a manifold is provided on an entrance of at least one of the pipes for reducing turbulence.
  15. 15. A hydroelectric generating system according to any preceding claim includes a syphon which is established between at least one of hydroelectric turbines and a pipe outlet.
  16. 16. A hydroelectric generating system according to any preceding claim wherein valves are located at interconnects, nodes, junctions or connections between two or more pipes.
  17. 17. A hydroelectric generating system according to any preceding claim wherein outlets of pipes of the network are disposed at different locations, in a tidal zone, so that valves are opened in a sequence according to location and tidal height, in order to maximise the period of electricity generation.
  18. 18. A hydroelectric generating system according to any preceding claim which is deployed as a temporary structure.
  19. 19. A hydroelectric generating system according to any preceding claim includes a mesh which is movable to cover an inlet of a pipe and removable when water is expelled from the pipe.
  20. 20. A hydroelectric generating system according to any preceding claim wherein valves are opened and closed by a servo or an actuator.
  21. 21. A hydroelectric generating system according to any preceding claim wherein signals, indicating absolute and relative sea levels, are obtained from buoys and/or measuring stations and/or satellites and are processed by a computer to obtain control signals for control, valves in response to variations in weather conditions, such as variations in air pressure or storm surges.
  22. 22. A hydroelectric generating system according to any preceding claim includes a holding tank with a weir located therein.
  23. 23. A hydroelectric generating system according to claim 22 wherein the holding tank has sluices over which fish can swim or bars through which fish can swim, thereby avoiding ingress into a turbine.
