Abstract
The present invention relates to an electricity generating module. In particular the invention has a square base footprint measuring 20 metres by 30 metres with a side elevation of 3 metres high on all sides. It is made of standard range shipbuilding grade steel plate. The structure is anchored to the ground beneath the water. The said structure is a steel box fabrication filed with air, in which a moving water-weighted weight rotates on a central shaft which drives a hydraulic pump. The module utilizes the energy produce by waves of longer lengths: 50-100 metres. The advantage of the module is that no fossil fuels are used as the total energy produced results from the constant and predictable supply of wave motion. There are no carbon dioxide emissions from the device. This module's optimum environment is ideally in 40-60 metres depth of water, 5-10 kilometres from the shore accessing large wave swells. Inside the module a centre shaft continuously rotates due to constant wave motion. The hydraulic pump is connected to hydraulic drives which turn the generators. <Figure 1>
Description
The present invention relates to the generation of electricity. In particular the invention relates to harnessing energy.
Background to the invention
A wave power module is a device for harnessing the sea's energy and converting that energy into electricity. Wave power or wave energy comes from the waves in the ocean. The tolling motion of the waves is harnessed to generate electricity. Turning waves Into watts might seem far fetched but harnessing power from the ocean is a very recent and new development, in time this method will gradually join the ranks of wind and solar as a source of renewable energy. The idea is to harness the undulating action of waves to generate usable energy, One popular existing version of a module or wave energy converter is the Peiamis
Machine. It floats aiong the surface of the water anchored down on one end. These wave energy generators were the first ever developed and put to use. Multiple Peiamis machines combined created wave forms for generating off shore electricity. The module is designed to be highly resistant to the forces of the open ocean and would be a very resilient renewable energy source, This module converts the wave motion to electricity by powering eiectrical generators,
Summery of the Invention
The module Is a structure that floats on the surface of the water,
This structure size is 30m x30m x 3mts high. The structure is hollow, filled with air. It is made of steel plate. The walls are reinforced with a steel lattice frame support. Inside the module contains a revolving weight coupled to electric fixed magnet generators. It would be positioned In the sea wherever there are waves of long duration and of suitable wave lengths, I.e. lOOmte in length,

The structure contains a centre vertical shaft, which is supported on either end by a tapered roller bearing.
A singular circular railway track runs on an outer circle, which is fixed in position by support beams. The support beams are connected at the top and bottom to the steel lattice structure.
The lateral beams of the weight carriage are connected to the central shaft.
The opposite ends of the lateral beams are connected to the weight carriage.
The weight carriage consists of a ferro concrete container weighing 30 tonnes, half of that weight consisting of water. The weight carriage is stabilized by steel wheels that grip either side of the railway track. These wheels are connected to electric motors which are controlled by a centrifugal switch.
Power supply to the motors is from a shore grid. These motors are switched to ON by the centrifugal switch when the weight carriage slows to a certain speed.
There is a hydraulic pump connected to the central vertical shaft, which in torn powers hydraulic drives on fixed magnet generators.
During suitable wave conditions this weight would rotate in a complete revolution around the central vertical shaft. The liquid weight content will facilitate the smooth rotation of the weight carriage. This is aided intermittently by the electric motors on demand by the centrifugal switch.
