Description

POLLUTION FREE ELECTRICAL POWER GENERATOR

BACKGROUND OF THE INVENTION

FIELD OF INVENTION

The present invention relates to a low speed, high torque rotary drive which is particularly useful in conjunction with gearbox driven generators such as wind power generators, where high torque can be reduced with this device that is applied to the gearbox whereby to generate power. This process can also be implemented on automobiles, homes, small business and at sea to produce clean electricity at a reduced cost for multiple applications

Another object of this device is it could be applied to any high torque required gearboxes applications. This invention relates to the generation of electricity and more particularly this invention relates to the method and apparatus used to generate electricity.

RELATED ART.

The present invention remedies the disadvantages and shortcomings of the prior art by reducing the required torque to turn the gearbox whereby the generator to generate electricity. The statements in this section merely provide a global need and background information related to the present disclosure and may or may not constitute prior art.

The present invention is similar to the large MW windmill type design where large long blades crate a low speed high torque for the gearbox to increase the speed of the generator, during the period the wind is blowing. The windmill has two major downside, that is the blades turn at different speeds which causes two more major problems one is that gearbox get damaged at high speed and upkeep are high, the other issue is frequency cannot be maintained to produce AC power directly therefore power losses, the other downside is its cost because windmill are reaching heights as much 200 meter at tip of the blade and each blade as long as 100 meter. The present decade has become a critical period for mankind globally and energy consumption continues to grow worldwide, as a result of population explosion, the decommission of Fukushima Daiichi Nuclear power plant due to the disaster along with Germany's decision to decommission all of Germany's nuclear plants permanently for safety, and there may be more to come, this has accelerated industrialization and economic growth and social development globally.,

There is an increase public awareness of the social and environmental problem related to production and consumption of CO2 related fuels.

Efficiency in the production of electricity is one of more critically important technical problems of the day. At a very time that the world's economy and the economies of the worlds industrial countries are becoming increasingly dependent on the consumption of electrical energy, there is a growing realization, the main source of this energy the earth's non-renewable fossil fuel reserves, will inevitably be exhausted and that in any event, the natural environment of the earth cannot readily assimilate the by-products of fossil fuel at much higher rates than it does at present without suffering unacceptable level of pollution whereby climate.

There is considerable agreement among scientists around the world that the byproduct of electricity is hydrogen as fuel will emerge as ultimate clean energy for the future. One of the raw material out of which hydrogen is derived, and covers 70% of the total surface area of the earth is water.

In the present invention all of these major issues are addressed and the outcome is excellent, further more this invention can be operated continuously and reliably at low cost almost anywhere. SUMMARYOF THE INVENTION

The object of the invention is to generate clean electrical energy by a new and improved method.

Another object is generate electricity that is AC power generated similar to the current method used, which is fossil fuel, direct engine driven generator sets. Except that, this present invention the generator is driven by its own power whereby gearbox and generator after an initial external start. Where AC electricity at 60Hz or 50Hz is generated by said generator, at constant speed required by design, power is recycled upon which only one third of the power is consumed by the motor in use, after initial start by external source. The balance of«the power can be consumed elsewhere, at zero emissions.

The high-torque ratchet reciprocating and energy generating device comprises of three parallel long rigid power arms. These arms play a vital role in producing clean energy, and synchronize AC power production where there is no need for inverter from alternating current to DC to AC, for the rpm is maintained for designed frequency requirement.

The high degree of torque and the continues rotation of the gearbox is overcome by the ratchets mechanisms and one way clutch bearings housed on one end, each of the long rigid power arms. One end of each long power arm is attached to two or more ratchets and a sprag clutch or one way clutch bearings which is sandwich between said ratchets, on a common shaft whereby the said shaft is attached to turn a helical or a planetary type of a gearbox, to bear the high torque created by the gearbox to rotate the generator at the required rpm for 50Hz or 60Hz .The other ends of the long rigid power arms to a crankshaft type or conveyer type reciprocating device.

There are several methods of achieving a common goal of turning the high torque created by helical or planetary type gearbox to generate electricity. On smaller generators, where one end of each rigid power arm on the generator side of the invention is fixed to two ratchets and a one way clutch bearing housed on a common shaft, each rigid power arm has two ratchet mechanism on each side of the rigid power arm and a one way clutch in the middle of the said arm, to turn the high torque created by the helical or planetary gearbox and generator.

To achieve the reciprocating of the long rigid power arms towards the electric motor end where reciprocating of the long rigid power arms is taking place during electricity generation, in this method it is attached individually, to three journal on the crankshaft by means of linear bearing & motion system. The linear bearings will be attached to a crankshaft journal saddle bearings and the linear shaft of the linear bearing as in FIG 9 will be attached at the end of rigid power arm whereby upon rotation of the crankshaft by an external force, the long rigid power arms reciprocate. Each full rotations of crankshaft the three rigid power arms attached to the crankshaft will be respectfully 120 degrees apart and each arm is limited to an angular excursion ranging between 12 degrees and 40 degrees depending on the outer circumference of the crankshaft journal rotation. Thus turning the gearbox whereby the generator.

Second method is for larger generators as in FIG.1 where the long rigid power arms are attached in similar manner as the first method. Where one end of the said long rigid power arm which is located on the generator side of the invention has two ratchet mechanism on each side of the long rigid power arm and a one way clutch in the middle of the said long rigid power arms. That is housed in a common shaft to turn the gearbox whereby generator. The long rigid power, arms can be as long as required by design engineering to reduce torque. The other end of the long rigid power arm which is located at the electric motor side is ratchet, reciprocated and the degree of movement which is much wider in larger systems and therefore are individually guided, controlled the up and down movements by a separate upright conveyer type system in a large frame. The synchronized and uniformity movement is controlled by electric motor, gears, and transmission roller chains and micro processed to achieve the desired frequency 50Hz or 60 Hz in this design.

The ratchet reciprocating of the long rigid power arm and uniformity is caused by three sets of upright conveyers individually framed as in FIG. 6 - 7 two set of transmission roller chains for each long rigid power arm. All sets of roller chains runs vertical on separate individual shafts and on identical size gears attached to the shaft at upper end supported by a independent frame which extends to the lower end of the said conveyer to support the conveyer structure, for each long rigid power arm and a pair of transmission roller chains, the lower end of the roller chains in pair of two are mounted on the said frame on two individual shafts and gears with each shaft mounted separately with gear for the transmission roller chain, each roller chain next to each other with four gears and two shafts are mounted to the frame with bearings, two for each said pair of transmission roller chains and a shaft, the other two gear is to attached to third shaft which is below the individual shafts with gears with each individual shaft. The difference between the individual said shafts and third shaft is that it's below the individual shafts and that it runs the full length of all individual shafts and whereby attaches to all of the reminding above gears on the lowest shaft, this shafts is turned by a separate electrical motor where the power is consumed which is generated by its own said generator, after been started by an external source of a much lower power than that the said generator is producing. As shown in drawings.

In present invention the external source of power can be fossil fuel driven engine to get the system in motion to producing power, immediately after the generator is producing full power as designed generator, a electric motor can take the place of the said fossil fuel motor to continue run the generator at on one third the cost of power produced by the said generator at the same time. That means, two third of the power produced by the generator can be used elsewhere, with zero consumption of fossil fuel after the initial start and zero emissions, this system of invention can continue to run until shutdown by disconnection of power to the electric motor.

Another method of reciprocating the three long rigid power arms towards the electric motor side of the invention is Ball screw assembly method on each arm separately and operated individually and synchronized by micro Drocessor. This method would be best applied to a vertical design of the invention.

Yet another method of achieving the reciprocating of the long rigid power arms on the electrical motor side is RPS+ PG Mechanics drives for reciprocating motion and roller pinion system or gear and track system, all controlled by micro processor. This method would be best applied if the design of this invention is horizontal.

The advantage of a vertical system is, in the vertical system of the said invention is that the downward reciprocating torque at the electric motor end of the long rigid power arms can be further reduces by increasing the mass weight by up to 100% of the torque required to turn the generator, at the electrical motor end where the rigid power arms are connected to conveyer chains type system, ithis is achieved by adding a large water tank to each arm that can be filled and drained repeatedly as to increase or decrease the pressure on the arms, this would reduce the torque from the generator when arms are pulled down, the downwards motion reduces the torque because of gravity and the pull of the said additional weight thus further reducing the required torque to the motor to turn the generator.

This present invention can also be implemented on open sea as in FIG. 1 1 where a continues up and down movement of the long rigid power arms by inflating and deflating the balloons in this diagram causing the arms to turn the gearbox whereby the generator that can generate electricity.
