Abstract

The elevator includes a hollow column 1 secured to the sea bed 12 and having a tide inlet 13 at the base below low tide level 11 and a valved air outlet 4 at the top to allow the incoming tide to rise within the column to high tide level 10. An upper, inner tank 2 receives water drawn from an lower, outer tank 3 via pipes 14, 8 as the tide recedes and creates a partial vacuum within the column 1. As the tide rises again, the water flows freely from the inner tank 2 via valve 5 and pipe 9 to a reservoir, turbine and generator not shown.

Description

TIDE LEVEL ELEVATOR.
The invention relates to a Tide Level Elevator which includes a hollow column open at the bottom with an air outlet valve at the top, an inner tank, an outer tank, four one-way valves and three interconnecting pipes.
Currently, tidal power, based on a barrage system, has a very limited application to the generating of electricity because the tides are variable and intermittent and create a comparatively short head of water to power turbines. The available useful running time is limited to about 5.5 hours during the approximate 12.5 hour period of outgoing and incoming tides.
An object of this invention is to provide a means to raise the tidal water to higher level than that of its own at full tide, under its own momentum.
Accordingly, this invention provides a re-inforced sealed column with a one-way air outlet valve at the top and tide intake/outlets at the base. The column also contains an inner tank secured near the top.
The incoming tide reaches its high level both within the column and the outer tank and as it recedes, the height of the water within the column is held, thus creating a partial vacuum.
Atmospheric pressure on the surface of the sea outside the sealed column will support a column of water up to a maximum height of 10 metres. The vacuum causes the water to syphon from the outer tank into the inner tank from which it eventually flows into a reservoir supplied also by other similar units. The reservoir, after its initial filling, would provide a continuous regulated flow from a level approximately 70% higher than high tide level, to power turbines. Preferably, the sealed column would be made from reinforced concrete or metal or other suitable material capable of withstanding the internal pressures created by the partial vacuum.
A preferred embodiment of the invention will now be described with reference to the accompanying drawing which shows a side view of the whole invention with a view of the sealed column interior and the outer tank interior.
2. As shown in the drawing, the invention comprises a vertical column 1 which is secured to the sea bed, 12. Fixed within column 1 is tank, 2. As the tide rises through tide intake/outlet 13, air is expelled through outlet valve 4, until high tide level 10 is reached. The tide also rises into outer tank 3 via tide intake pipe 14 and water inlet valve 7 until high tide level 10 is reached.
Intake/outlet 13 and intake of 14 are located below low tide level 11. As the tide recedes, causing a partial vacuum in 1, valves 4,5 and 7 close, retaining water in tank 3. Water inlet valve 6 opens, allowing water to syphon from tank 3 via pipe 8 into tank 2 where it is retained. When the tide rises again, valves 4, 5 and 7 open. Valve 6 closes and the water from tank flows, via valve 5 and pipe 9, into a reservoir, not shown, and thence through a turbine. The invention would be located in selected coastal areas, in dock areas, tidal rivers or suitable fresh water rivers. It could produce electricity to be used locally or fed into the national grid.
