Abstract
ABSTRACT The present invention relates to an electricity generating module. In particular the invention has two spherical floats 30m in diameter with a connecting beam which supports a water turbine suspended on a steel shaft. The turbine assembly has a buoyancy which will allow it to be pulled into the prevailing tidal flow. The structure is made from steel. It has a buoyancy chamber which is filled with air, and when the tidal flow tums the turbine this rotation is transferred to the generator drive disc by the shait. The structure is anchored to the sea bed by cable. This module uses an axe] flux generator but could be adapted to use conventional generators.
Description
Title:
A module to generate Electricity using tidal energy
Field of Invention
The present invention relates to the generation of electricity. In
particular the invention relates to harnessing energy.
Background to the invention
A tidal power module is a device for harnessing the sea’s energy
and converting it to electricity. Tidal power comes from the tide in
the sea and in particular channels and inlets.There are many
devices in existence that sit on the seabed. These are anchored
down principally by weights and have limited power.
Summerv of Invention
The module is a structure that floats on the surface of the water.
The structure consists of a turbine, a buoncy chamber,two
spherical floats each float 30mts in diameter connected together
by a 30mt beam.
The floats are anchored to the sea-bed by cable attached to
mouring points. at the outer side of each float. In the centre of this
beam there is a bearing compartment which supports a 40 meter
shaft. A turbine assembly is connected to one end of the shaft
which consists of a bouyancy chamber, turbine blades and cowel.
The opposite end of the shaft is connected to a drive disc which is
the centre of an axel flux generator. The generator is connected to
the beam by a generator rack. when there is no tide flowing (i.e.
full tide )the turbineassembly will hang down from the beam due
to turbine assembly having a 10% negative bouyancy (achieved by
bounancy chamber) . During a tidal flow the assembly will swing
into a working position. This turns the turbine assembly and
generator disc drive by way of the shaft. The turbine assembly will
rotate in the same direction at all times in either a backward or
forward tidal flow so enabling the use of parabolic curved turbine
blades.
