Abstract

Water kinetic energy driven hydro turbine is disclosed to generate electricity utilizing the kinetic energy of the flowing water. The design of the turbine is such that it is conical shaped and the fins are attached in such a way that it gives a pointed face in one side and a broad fin end in another side and all the fins are curved in shape and attached to the turbine base in a manner so that it provides an angular shape, the turbine fins also have deep invert fold which gives space and converts maximum strike power of flowing water into torque. The screw like structure of the turbine allows is to cut the flow of water without disturbing the flow and then the water flows deeper into the groves of spiral fins and set the rotor in rotation. One or more such turbines are installed inside a floating case.

Claims

AMENDED CLAIMS
received by the International Bureau on 07 April 2016 (07.04.2016)
WE CLAIM:
1 to 17 (DELETED)
18. A turbine for harnessing hydrokinetic energy from running water, the turbine comprising:
a rotor; and
plurality of blades, wherein each of the plurality of blades is formed out of right angle triangle shaped material and wherein theright angle triangle shaped material is given a curved shape such that its base is straight and perpendicular side is curved; wherein the base of the plurality of blades is fixed to the rotor along its longitudinal axis.
19. The turbine of claim 18, wherein the turbine is of conical shape with narrow side of the right angle triangle shaped material forming pointed side of the conical shaped turbine, and wherein angle of the conical shape is in the range of 30 to 40 degrees.
20. The turbine of claim 18, wherein speed of the running water is more than 0.25 meter/sec.
21. The turbine of claim 18, wherein the turbine is partially submerged in the running water for harnessing the hydrokinetic energy.
22. The turbine of claim 19, wherein the curved shape of the blades provides deep invert folds between the blades, and wherein water enters the deep invert folds through the pointed side of the conical shaped turbine thus preventing disturbance in current of the running water.
23. A hydrokinetic energy conversion apparatus for harnessing energy from
running water, the apparatus comprising:
two or more turbines, each of the two or more turbines comprisinga rotor and plurality of blades; wherein each of the plurality of bladesis formed out of right
9 angle triangle shaped material and wherein theright angle triangle shaped material is given a curved shape such that its base is straight and
perpendicular side is curved;and wherein the base of the plurality of blades is fixed to the rotor along axis of the rotor such that each of the two or more turbines take a conical shape with pointed side of the plurality of blades forming pointed side of each of the conical shaped two or more turbines; and a floater case configured to float on water and hold the two or more turbines such that the two or more turbines are partially submerged in the running water; and wherein the two or more turbines are fixed on the floater such that the pointed sides of any two of the two or more adjacent turbines are in opposite directions.
24. The apparatus of claim 23, wherein the rotors of the two or more turbines are connected by sprocket and chain arrangement.
25. The apparatus of claim 23, wherein the floater case is anchored to keep it stationary in the running water.
26. The apparatus of claim 23, wherein the floater case is made of a light weight material.
27. The apparatus of claim 23, wherein the floater case is of hollow cross section to enable it to float on water.
28. The apparatus of claim 23, wherein the floater case incorporates metallic sheet on bottom side to direct the running water towards the blades of the two or more turbines.
