TECHNICAL FTEUD

[001] The present disclosure relates to the field of power generation systems. More particularly, the present disclosure relates to an onshore tidal power generation device comprising a tangential flow turbine drum and revolutions rate intensifier.

BACKGROUND

[002] Generally, tidal current energy is to be harvested at onshore or coastal site for generating electrical energy. Conventionally various axial turbine and paddle wheel turbines are used for tidal power generation. These types of turbines are to be stationed in shallow or deep ocean and rotated at a lower rpm for the same energy input.

[003] Furthermore, the turbine wheel which is rotated by the virtue of the flowing water and the energy obtained from the flowing water is transmitted to the roller of the generator by two sets of chain wheels, so that the electricity generated by the generator can be directed to the onshore socket. These results less improvement of output and more vibrations are produced. This system cannot solve the energy crisis and also huge amount of greenhouse gas emission is released into the environment.

[004] In the light of aforementioned discussion there exists a need of a device that would ameliorate or overcome the above mentioned disadvantage.
