Abstract

A generator includes a turbine with blades (2), a reservoir (7), an air pump (3), an air tube (4) and a dynamo (5). Water is filled in the reservoir (7) and the turbine is submerged in water. Air is pumped into the air tube (4) beneath the blades by the air pump (3) and is delivered to the water. The blades (2) are rotated by the air delivered into the water so as to rotate the dynamo (5) to produce electricity.

Title of Invention GENERATOR

Relevant science of the invention Mechanical and electrical engineering

Background of the relevant arts or science

Nowadays, energy sources are presenting themselves as problems to mankind. For household and industrial facilities, electricity production nowadays relies on hydroelectric dams, coal, oil, and nuclear power, solar energy or wind, etc. These energy sources either progressively diminish or generate too much pollution. For example, the construction of new hydroelectric dam is quite difficult due to the impact on the environment. Additionally, the coal- generated electricity plants pollute the air so that the anti-coal plant campaign is carried out by neighboring communities. Similarly, the nuclear power plant is protested against due to the radiation leaks and frequent explosion of the plants. The electricity production by solar cells has higher cost and can be produced only when the sun is out. Even the production of electricity from wind turbines is similarly difficult because electricity can be produced only when the wind is strong. Also there are resistances from communities due the noise pollution caused by rotation of the rotor, flashing lights caused by rotating rotor which affect the nearby residents and obstruct the scenery.

Characteristics and purpose of the invention

This invention is intended to produce electricity without having to rely on external fuel sources or not to create any pollution and can generate energy by itself. The invention works on the power of the air buoyancy in the water as water-driven turbine to power the generator producing electricity. The process begins by pumping air underneath the turbine blades and the air underneath the turbine blades will support the continuous rotation of the turbine. Numerous water sources can be found such as canals, rivers, treated water from household use or industry plants and sea water. In this case, the oxygen level in these water sources will beneficially be increased and the water is additionally treated. This system does not encourage water loss because the water is saved in reservoir unlike the hydroelectric dam. However the water may evaporate but not too much, so the invention produces an efficient use of water. The invention can accommodate the industry plant, distant communities, and households and can be fashioned as portable electric generator.

Complete disclosure of the invention

This generator has 12 key components: turbine, shaft axis, magnetic seal, air pump, air tube, dynamo, reduction gear, chain sprocket, chain, reservoir and water. The air is pumped into the water underneath the turbine by air pump. The pumped air stays afloat underneath the turbine blades and drives the turbine, designed to keep the air inside. When the first turbine blade moves, the pumped air will fill the next blades and generate continuous propulsion. A set of submerged turbine blades will prevent resistance in the process of the turbine spinning up to the top and down. The turbine blade has a curve design with the purpose of reducing the resistance of water. The pumped air inside the turbine blades, allowing the turbine to rise, will be released before the turbine spins down. The shaft axis of the turbine protruding outside the reservoir is sealed to prevent water leakage. The shaft enhances the reduction gear rotation faster at the speed of 1500 rpm in order to propel the generator.

The amount of air pumped into the turbine within 1 - 2 seconds, equals the volume of air filling one turbine blade. To achieve maximum effectiveness of the turbine, at first, we use external electricity or battery to power the air pump to pump air inside the reservoir. After the turbine blade starts to rotate and propels the dynamo which generates power to the air pump or some of the produced electricity will be reserved in the battery and can power the air pump continuously. This generator will continue to run by itself without relying on external fuel sources. To enhance the power production, we can use multiple turbine sets and reservoirs, stacking up on a vertical line. The pumped air propelling each turbine set will create propulsion that drives the set of reduction gear interconnected with sprocket. This will add momentum to the bottom set of turbine connected to the reduction gear and dynamo and helps generate more electricity.

The 2 control pads angled at 30-45 ° placed on top of the turbine blades will control the air navigation up to the turbine blade (as shown in the illustration).

Claims

1. The generator uses dynamo propulsion to produce electricity from the rotation of the turbine submerged in water. Turbine is rotated by the air inside the turbine blade. The air is pumped into the air tube. Naturally, the air will rise to the top. The blade filled with the air will move upward, the next blade will replace it and so on. When the turbine spins up to the top, the air beneath it will float away before the turbine blade rotate back into the water. This creates continuous rotation of the turbine blades.

2. A form of turbine blades can be specified in claim 1. It is designed to provide optimum air entrapment. The turbine blades are attached to the shaft axis. Although there is some air escaping from the first turbine blade, the escaping air will float up into the above one over and over again. The curve turbine blade is designed to reduce the resistance in the water when rotating down and has side covers to ensure optimum air entrapment. This will allow the air to escape faster once the blade reaches the highest point and there will be no air left inside. The set of turbine blades is fully submerged in order to reduce the resistance and enhance the continuous downward rotation. The size of the turbine blade depends on the amount of power needed. The number of turbine blade should be at least 8, depending on the diameter of the turbine. The blade number shall be increased according to the size of the turbine diameter. The more the cavity inside the blade is extended, the more the propulsion is enhanced. The full set of turbine blade is attached to the shaft axis which is attached to the reservoir. The shaft axis is protruding out off the reservoir with the magnetic seal to prevent water leakage. The axis connected to the reduction gear is used to increase the speed up to 1,500- 1,800 rpm in order to propel the dynamo. The reservoir is filled with water to cover the blades.

3. The turbine blade and reservoir can be stacked vertically in a rack. The pumped air propelling each turbine set will create propulsion that drives the set of reduction gear interconnected with sprocket. This will add momentum to the bottom set of turbine connected to the reduction gear and dynamo and helps generate more electricity. The axis of the turbine shaft extending outside the reservoir will propel the chain sprocket. The interconnected looped chain enhances the superior propulsion force.

4. Aeration pumps specified in claim 1 , is equipped with the air intake pipe under the turbine blade. The size of the force of the air pump equals the volume of air. It is important to have the capacity to pump air within 1-2 seconds to retain the air of one turbine blade.
