Abstract

Abstract A water turbine is used to generate electricity with minimal environmental impact. The turbine located on the surface of water and is arranged with fins into water and running spirally along the longitudinal axis of the rod. Fins are arranged in a specified angle around a central axis. The entry point or contact point of fin to water is at 0 degree and passes through angles of 0, 60, 90,120,150 and 180 are involved along the longitudinal axis of the axis where the flow exits. 30~~ 01o0o

Description

EDITORIAL NOTE There are 4 pages of the description There are 3 pages of claims All of the water turbine blades or fins are made that they deal directly with water. It means that the fins are arranged with the specified angle around a rod or central tube and diameter was created much more could be added to the number of fins according to the specific distance from each fin with other fins . However, rotation speed is low and more power. (figurel) In this method, the spiral fins around the central axis are twisted together. (figure2) In this case, the central rod, a rod or tube which is long, past the middle of each fin and zero angle on one side and it gives 180 degrees to the other bottom of fin. And actually makes it into two independent parts. Other fm or specific angle is placed right next to the first fin. ( considering to situation and requirement are slightly different, we consider the 30 degrees angle to this comment. It means that for 360 degrees, if our first blade gives angle of zero and 180 degrees, the second fig gives angle of 30 degrees and 210 degrees and continue to the last blade.) (figure3) So that if the fin width is 20 cm and we are placed it in distance from 0 cm to 20 cm on the rod axis, the second fm is placed with the angle of 30 degrees next to 20 cm to 40 cm the first fin on the rod axis.(figure4) And also to last fin that is placed between 100 cm to 120 cm on the rod axis or with angle of 150 degrees and 330 degrees than the first fin, since then we want another fin with angle of 180 degrees and 360 degrees and this angle in rotational circulation is equal to 0 degree and 180 degrees and the angle is equal to our first fin.

So we put a fin with angle between 150 degrees to 330 degrees in distance 100 cm to 120 cm on the rod axis. We are created a full circle for turbine rotational motion. (figure 5) Note: fins are always placed perpendicular (vertically) to the central axis. Note: since the fins act just like a shovel so no need to get into deep water for fins. And regard to position turbine can be made very small diameter which causes the turbine to spin faster. Turbine rotational state : When the first fin is placed with angle of 0 degree and 180 degrees with a distance of 0 and 20 cm on the first rod , angle of 0 degree into the water and the other side of fin out of water with angle of 180 degrees and also fin angle of 0 degree and 180 degrees are in the different states to water. (figure 6) If we want to consider a general form for this case , you can refer to figure 7. In total we have a full circle in a spiral turbin-born. (figure 8) Note : the water level is always 0 degree and 180 degrees that the moment of entering the fin is 0 degree and the moment of exiting the fin is 180 degrees. Central axis of the rod , which is installed on the fins , the pressure of the rod into the fins cause to rotate the fins. This rotation is transmitted to the gearbox and generator. The central rod axis past within the ballbearing and the ballbearings are also mounted on the chassis till the rotation is done without difficulty.

Chassis : the whole turbine is located on it and length varies depending on turbine and is mounted on the floating . (figure 9) Floating : considering that the turbine is located on the water and due to fluctuations in weather and tide the water goes up and down. And the fluctuations in water, turbines should be a constant state than water. Best use of floating number is in longitudinal sides of the turbines. The water changes always keep the contact stationary blades. Note : As regards turbines sides may have different weights , floating should be placed that turbines to be in balance to water. Note : considering to the position and intensify of currents and water depth and weight of the turbine use different floating which are certainly effective in the direct movement of water. You can minimize this problem by putting distance between the floating to fins and also calculating the angle of changing the water and adjusting the angle of lateral fins , which are effective in diverting water. Note : best collision or clash of water to fins is direct collision of water with angle of 90 degrees .(figure 11) Wire holder : because the turbine is floating on water and should be fixed to the turbine blades to rotate in the water floating should be connected by 2 steel cables to fixed object on a dry. So that water deal with from opposite to fins with angle of 90 degrees. Note : if the water is 0 degree and 180 degrees in a full rotation of the turbine , entry point of fin to water is 0 degree and angles of 30,60,90,120,150 are involved along the longitudinal axis of the rod into water with direct pressure water and water flow into each fin continues to be steady from the moment of arrival till exit of fin. (figure 12) Note : water flow, width of waterway , type of generator and gearbox have a direct impact to the angle between the fins , the number and diameter of turbine . To produce stronger rotational force for generators can be used several turbines in parallel to each other and their rotational power transmission to another axis.

Claims (13)

1. All people need electricity.

2. Different methods are used to generate electricity everywhere that many of them caused by environmental destruction and also have high costs.

3. We are always looking for better ways to generate electricity that will not cause environmental destruction.

4. Everywhere there is water flowing can be used as river and canals

5. The rivers can be used as a source of clean energy.

6. The turbine does not require a big deep river, just as a river with common and consistent flow. we determine the size of turbine and type of generator according to the intensify of water pressure.

7. Old methods must be created in specific circumstances. For instance, building a dam or redirect water and etc.

8. In this method: Turbine is so easy to transport, installation and maintenances, energy does not need to start, due to floating , it has no impact on water and climate changes. Due to the small diameter does not require fundamental changes in the environment . The river does not affect to the environment and ecosystem faunas . It does not cause water and air pollution and can be moved easily . Rivers are a renewable energy.

9. For longer generators that simply adding the number of turbines in parallel along the longitudinal river .

10. In old water turbines, the fins always rotates around a specified axis as a full circle and fins are one after another into the water. But in these turbines, fins into water together as spiral along the longitudinal axis of the rod.

11. To enhance power turbines are used of several turbines together within a river. But a large number of turbines in the turbine can be used in parallel along the longitudinal river.

12. They had to already make a longer turbine for obtaining the required pressure which were caused small angle between the fins. The result was a large number of fins and low rotation speed. But in this method, despite the small distance between the tip of each fin to next fin, angle between them is high, it will reduce the number of fins and high speed. Because of the large diameter and the large number of the old turbine blades and just when the water pressure on the first blade was too much, other fin got into the water. So much power was not generated. But in this method, each fin separately gets into the water and the maximum water pressure is used and get out of the water. Therefore, its power is much more and greater

13. In all old turbines, turbines were spinning inside of water as a barrier. And the water was diverted around after dealing with turbine. In this turbine, each fin is separately as water barrier and the water will be diverted to both sides after dealing with it . because there are other fins with different angles on the sides, it causes more pressure on water. Old turbines were always fixed to land and changes of water (tide) and the weather had a direct impact on their function but these turbines are floating on water. And in any weather condition of the turbine fins with the water level of contact is constant and does not change. In this turbine, the total transverse pressure of the river is used in a time . After considering the above and that no type of turbine has been built with these specifications .There is no power plant which is activated with this type of turbine . So it considers this new turbine and I demand the record it.
