Description
The present invention relates to the generation of electricity. In particular the invention relates to harnessing energy. &¢:Lcrrou&Q.tbegv mice 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 rolling 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 Pelamls Machine. it floats along the surface of the water anchored down on one end. These wave energy generators were the first ever developed and put to use. Multiple Pelamis machines combined created “wave farms" 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 electrical generators.
The module is a structure that floats on the surface of the water.
This structure size is 30m x30rn 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, l.e. 100mts in Iengdi.
O 2 336389 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 turn 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.

The outer steel plate 1 is reinforced by a steel lattice), A central shaft 5 runs from the top 15 in the centre of the structure which is supported in tapered roller bearings 11 at either end at top 15 and bottom 16 of the structure. Two lateral beams 4 extend from the central shaft 5 to the weight carriage 3. The lateral beams 4 are permanently fixed to the central shaft 5. The ferro concrete weight container 12 is supported by the weight carriage 3. The steel wheels 6 on the weight carriage 3 are gripping either side of the railway track 7, which adds stability to the weight carriage 3 whilst in motion and are connected to electric motors 17. The ballast water 14 in the ferro weight container 12 will increase the inertia of the term weight container 12 at the top of each cycle allowing for a smooth rotation of the weight carriage 3. The hydraulic pump 8 driven by the central shaft 5 which in turn powers the hydraulic drives 9 which are attached to the generators .
Referring now to the drawing Figz showing the lateral beams 4 and the weight carriage 3 which will move clockwise around railway track 7.
Referring now to the drawing Fig 3 showing rail support beams 13 attached to the steel lattice 2. This drawing shows the position of the ferro concrete weight container '12 and the ballast water 14. Steet wheels 6 are attached to the weight carriage 3. The steel wheels 6 run on the raii track 7. The details show section of iaterai beam 4.
Fig 3 also shows the position of the centrifugal switch 18 on motor 17.
