The present application is related to United States patent number U.S. 2007/0130929, issued Jun. 14, 2007, for WAVE POWER GENERATOR, by Ghazi Khan, Shahnaz Khan, included by reference herein.
FIELD OF THE INVENTIONThe present invention relates to a power generator and, more particularly, to a generator that is driven from sea wave,
BACKGROUND OF THE INVENTIONThere are problems related with generating energy or power from sea waves. One of them is that the sea wave has a crest and trough, that when applied to a pressure chamber will produce a bidirectional force of air. Therefore a normal turbine will not function because it would oscillate back and forward. So this force would have to be rectified to produce a one way rotation on the turbine. Also the waves have different wave length and different amplitudes. This would affect the steady rotation that an electrical generator would need.
One solution is the Well's turbine that is been used in the Island of Islay, Scotland. Another solution is using floats, by using the up and down movement of the float to compress air.
The Well's Turbine in Islay Scotland will rectify the bidirectional force, but will not correct the problem of different wave length and different amplitudes of the waves. That could affect the rotation stability of the generators. And using a float to compress air is a very inefficient way of compressing air because it only uses the mass of the float and not the total mass of water that is being used.
It is therefore an object of the invention to produce useful energy from the sea waves.
It is another object of the invention to rectify or eliminate the sea waves variation in both length and amplitude, and to produce a constant output force.
It is another object of the invention to produce energy from sea waves in the megawatt and higher range.
It is another object of the invention to produce clean energy from the sea.
It is another object of the invention to use the full mass of water to compress air in the full cycle of compression. When the wave level go's up or down. Which is very efficient. And not a float which is very inefficient.
SUMMARY OF THE INVENTIONIn accordance with the present invention, there is provided a primary piston that is connected to a secondary piston that is part of a compressor. Primary and secondary pistons are connected by a connecting rod. The primary piston is driven by the pressure and vacuum produced by a pressure chamber that is driven by the variation of the sea waves. The output of the compressor is applied to a pressure tank. The output of the pressure tank is controlled by a control valve, so as to control the air flow that is applied to the turbine. The purpose of the primary piston and compressor is to rectify the bidirectional force that is produce at the output of the pressure chamber, The control valve is controlled by any electronic close loop control system that monitors the velocity of rotation of the turbine or generator. Therefore, this system will cancel the variations of the sea waves, length and amplitude and produce a force of air flow that is very stable for constant rotation of the electrical generator.
A complete understanding of the present invention may be obtained by reference to the accompanying drawings, when considered in conjunction with the subsequent, detailed description, in which:
For purposes of clarity and brevity, like elements and components will bear the same designations and numbering throughout the Figures.
DESCRIPTION OF THE PREFERRED EMBODIMENTThe purpose of the present invention is take the energy present in sea waves or any large body of water which has waves and produce motive force. Since a wave has variations in both amplitude and wave length, this will produce a force that will be bidirectional and has variations in the magnitude of force. This would cause the speed and force at the turbine 23 to variate, and would cause variation in both voltage and frequency at the electrical generator 10. The present invention will correct all of this variations and apply a force that is constant and completely under control to the turbine 23. Also since it is using a primary piston 24 and not a float, it is very efficient because this system uses the total mass of the water that is moving in the pressure chamber 1 which can be in tons and deliver energy in the megawatt range and higher.
The following is a description of the system in operation. The waves enter the pressure chamber 1 at the bottom. The pressure or vacuum generated by the pressure chamber 1 will be applied to the primary piston 24 via the intake and exhaust pipe 2, which also houses the piston cylinder for the primary piston 24 as seen in
Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
Having thus described the invention, what is desired to be protected by Letters Patent is presented in the subsequently appended claims.
