Abstract
ABSTRACT A module to generate electricity from water waves. The present invention relates to an electricity generating module. In particular the invention has a square base footprint measuring 30 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 filled with air-in which a moving water-weighted weight rotates on a central shaft which drives a hydraulic pump. The module utilizes the energy produced by waves of longer lengths: 50~100 metres. The advantage of the module is that no fossil fuels are used as the totalenergy produced results from the constant and predictable supply of wave motion. There are no carbon dioxide emissions from the device. The 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.
Description
The present invention relates to the generation ofelectncity. In particular the invention relates to harnessing energy.
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 inln 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 Pelamis 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 electridty. 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. i ‘ 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, tilled 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. ioomts in length.
OPEN TB P153115 IMSPECTEMI aunts sttrlcri 23 not EEILE 23 Jiiil. of S86147 2 The structure contains a centre vertical shaft, which is supported on either end by a tapered roller hearing.
A singular circular railway track runs on an outer circle, which is iixed 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 rriage 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 farm concrete container weighing 30 tonnes, half of that weight consisting of water. The weight rriage is stabilized by steel wheels that grip either side of the raliway track.
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.
