Definitions

  • the main idea behind this invention is to use the unlimited huge ocean water to produce electricity either on small scale or big scale according to needs and the geological structure of different places in the world.
  • Hydraulic power plants have been long known as a source of potential energy for generating electricity.
  • the initial high cost of construction of conventional hydro-electric power plants is estimated to be thirty times higher than the cost of the subject to this invention.
  • US patent 6,967,413 proposes a tidal energy system with a structure made of an array of support columns and panels that form a tidal containment wall that forms an artificial tidal lagoon enclosed by the structure or partly bounded by the shoreline.
  • the walls are turbine generators that are driven by the level differential of water created by the tides, wherein the water flows from a higher level on one side of the walls to a lower level on the other side of the walls.
  • the present invention relates to a sea-water hydro-electric plant using a saline- proof steel structure or made of concrete or other suitable material for sea water structure of dam design to pass the sea water from upstream side of sea water to the downstream side of sea water towards a coastal sea area via at least one pipe and/or tunnel according to requirements.
  • This dam could be floating the same as a big mother ship.
  • a series of water wheels and turbines are positioned at the beginning of the dam or in any suitable place for example every 15 or 20 meters along the length of the side of the dam enclosure, to convert the sea water flow to electricity power.
  • the water wheels can be adjustable to allow the wheels to be raised or lowered thus enabling the wheels to be placed in or out of operation as needed.
  • a sea-water hydro-electric plant dam comprises a saline-proof structure in particular of steel or concrete or any other material suitable to resist contact with sea water, configured to pass sea water from an upstream side at the outlet of the structure to a downstream side towards a coastal area by at least one pipe or tunnel arranged to discharge water inland above the level of the water table.
  • the saline-proof structure can in particular be a hollow body of rectangular shape or other shapes, preferably open at its top.
  • This sea-water hydro-electric plant dam comprises at least one water wheel connected to a dynamo/generator for generating electricity powered by the flow of water.
  • the water wheel and dynamo/generator are located at an adjustable level to allow water flow from upstream to downstream during high tide and low tide.
  • the sea-water hydro-electric plant dam may comprise a dam enclosure fixed on sea-bed or connected to the sea bed and movable/floatable like an oil rig, or a buoyant dam enclosure.
  • the inventive sea-water hydro-electric plant dam usually has at least one pipe or tunnel leading from the bottom of said structure to a location inland for the outflow of sea water entering the structure, such pipe or tunnel being arranged to discharge water inland above the level of the water table.
  • This pipe or tunnel may branch inland to a number of buried discharge pipes having outlets above the level of the water table, these discharge pipes usually being substantially vertical, inclined or substantially horizontal and are buried in the ground.
  • the enclosure comprises at least one inlet adjacent its top edge and at least one outlet adjacent its bottom.

  • the outlet(s) is/are located at an opposite side of the enclosure
  • the enclosure has a bottom sloping down from said one side to said opposite side.
  • Another aspect of the invention is a method of generating electricity by a sea- water hydro-electric plant as set out above, which comprises intaking sea water adjacent the top of said structure, flowing the intaken water against at least one water wheel located inside the structure and connected to a dynamo/generator, exiting the seawater from adjacent the bottom of the structure, and delivering the exited water to a coastal area by at least one pipe or tunnel, which delivers the water that is released inland in the coastal area at a level above the water table.

  • FIG. 1 shows a first embodiment of the entire mechanism according to the present invention.
  • a diversion dam 01 projecting partway into deep sea near the coast, like an oil rig platform based or connected on the seabed.
  • the dam 01 is typically a steel structure.
  • the operation of the system is apparent in that sea water entering the dam at inlet 02 is diverted by a diversion spillway 03 from upstream to downstream towards a coastal area where the water exits at outlet 04, the water first passing via water wheels 20 (see FIG. 3).
  • the water wheels are connected to a suitable turbine-dynamo generator to generate the electricity in conventional manner.
  • the wheels 20 are driven by power of sea water to operate the turbine for power generating units.
  • any number of water wheels 20 and dynamo / turbines can be used within the scope of the present invention.
  • the said water wheels 20 and dynamo may be adjustable according to water flow.
  • the dam 01 could be fixed at a certain height according to requirements or could be floatable and movable.
  • FIG. 2 is another embodiment where the sea water after passing through the wheel 20 will move through a pipe or tunnel 06 on the seabed and merges the water into a coastal area at outlet 04.
  • FIG. 3 shows in plan view, in section along A and in section along B, a dam enclosure 01 fitted at its inlets 02 with an internal pipe 10 for delivering water to a water wheel 20 supported in the enclosure 01 on a structure 21.
  • the shaft of the water wheel 20 is connected to a turbine/dynamo, not shown.
  • the dam enclosure 01 has a sloping bottom 25 for delivering the water from wheel 20 to the outlet 05 at the opposite end of the bottom of the dam enclosure 01 , so the outflowing water can be taken off by the pipes or tunnels 03 or 06 (FIGS. 1 and 2).
  • FIGS. 4 and 5 are schematic representations of another embodiment of the invention showing the dam enclosure 01 in the sea, offshore and connected by its lower outlet to a pipe or tunnel 03 which extends inland over the coastline 35 where it is buried and separates into a number of branches 03' which each terminate with a vertical discharge pipe 30 or an inclined or a horizontal discharge pipe directed towards the sea side, as per requirements.
  • These pipes 30 discharge the water from outlets 32 at their lower ends, located above the level of the water table 36 in the sand layer above the usual rock and earth layers. The lower ends at outlets 32 are thus above the water table 36 but below the sea level, in particular below the level of the outlets 5 in the enclosure 01.
  • the pipes 30 could however go deeper as per requirements.
  • the discharge pipes 30 can have computer-controlled gates for controlling the outlet of water to avoid flooding of the water table 36, as necessary, by allowing time for the outlet water to mix with ground water.
