A DEVICE FOR LIFTING SEA WATER BY HARNESSING LINETIC ENERGY OF SEA WAVES

Abstract

This invention relates to a device for lifting sea water utilising the kinetic energy of sea waves. It consists of a venturi and a delivery system. The venturi has a movable floating valve fixed thereto and obstructions to limit its movement in the venturi. The delivery system consists of a hollow tubular body which houses a non-return valve, sieve means and connecting means to connect the tubular body to conduit of desired length extending to storage tanks located either on or off-shore.

2. The device as claimed in claim 1, wherein sieve means (M1) are also provided at the mouth of the venturi.
3. The device as claimed in claims 1 & 2 wherein the sieve means is wire mesh or net of non-corrosive type,
4. The device as claimed in any of the above claims wherein the floating ball is movably fixed to the venturi by link means such as chain or rope.
5. The device as claimed in claims 1 to 4 wherein the conduit means is a pipe of any desired length.
6. The device as claimed in claim 5 wherein the pipe is flexible
and is provided with support means.

7. The device as claimed in any of claims 5 or 6 wherein the the delivery end of the pipe is fixed to the storage tank,
8, The device as claimed in claims 1 to 7 wherein the storage
