Abstract
Arrangement for feeding water into a reservoir located at a level above that of the ocean by utilising energy produced by the movement of waves thereof. An air cushion-forming portion of a first chamber communicates with an air cushion-forming portion of a second chamber. Water is supplied to the second chamber via an intake pipe and associated back pressure valves plus adjacent rising pipe. As a result of equivalent pressure variations in the first and second air cushion-forming portions caused by movement of the waves, water is lifted from the second chamber in a pipe via additional back pressure valves along with a further rising pipe plus pump to a higher lying, third chamber and from there to the reservoir.
Claims8
An apparatus for feeding water into a reservior located above an ocean level, said apparatus comprising:
- a first chamber having a downwardly opening housing for receiving a level of water which rises and falls in response to the waves of an ocean outside said chamber, said housing defining a first air cushion-forming portion above the level of water for compression and expansion of air therein in response to movement of said level of water;
- a first work chamber adjacent said first chamber for receiving a level of water and having a second air cushion-forming portion at an upper end in communication with said first air cushion-forming portion;
- a water intake conduit for feeding water from below into said work chamber;
- a first back pressure valve between said intake conduit and said work chamber to prevent a backflow of water from said work chamber into said conduit;
- a water lifting arrangement including a water guide pipe extending from said first work chamber to convey water therein in response to a rise of the water level in said first chamber and a first pair of back pressure valve in an upper end of said guide pipe to contain water therebetween;
- a piston and cylinder arrangement between said first air cushion-forming portion and a space in said guide pipe between said pair of back pressure valves for forcing water in said space past an upper valve of said pair of valves in response to a rise of the water level in said first chamber;
- a first rising pipe connected to said water intake conduit to receive water therefrom and to said first air cushion-forming portion to receive air therefrom for building up added water pressure upstream of said first back pressure valve;
- and
- a second pair of back pressure valves in said water intake conduit on opposite sides of said rising pipe.
