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 turns the turbine this rotation is transferred to the generator drive disc by the shaft. The structure is anchored to the sea bed by cable. This module uses an axel 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.
Summery 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 turbine assembly 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.
