Abstract
A device for transmitting sea water from a lower level to a higher level by means of sea surge striking the intake pipe to generate air pressure in a sealed chamber and to cause the water therein to be transmitted upwards into the next higher sealed chamber. The sea water is finally lifted to a reservoir at a given elevation.
Claims4
A sea water reservoir device having a base in the sea comprising a plurality of vertically stacked sealed chambers, each having an upper portion and a lower portion,
- an air inlet in the upper portion of each chamber,
- a water inlet in the upper portion of each chamber,
- a water outlet in the lower portion of each chamber,
- water transmission means connecting each water outlet with the water inlet of the chamber above for transmitting water up the device,
- first check valve means in each water inlet for only letting water in,
- second check valve means in each water outlet for only letting water out, and
- intake pipe means connected to each air inlet from the base of the device for transmitting pressure from sea waves compressing and exhausting air in said pipe means
- whereby the successive surges from the sea waves alternatingly compress and exhaust the air in said intake pipe means and each sealed chamber thereby forcing water through said water outlets and said water transmission means to the next chamber stacked above, the water outlet of the uppermost chamber being connected to a reservoir.
