Document Type and Number:
WIPO Patent Application WO/2016/200344
Kind Code:
A1
Abstract:
The main interest of our invention is the method of transforming the motion energy that the rivers with high flowrate and the powerful deep sub-flows in the straits formed into electric energy. The system is composed of two sections: I- A Cylinder System with Interior Wings It is a system composed of a metal cylindrical pipe and some wings fixed vertically lengthwise on the interior lateral area of this cylinder pipe through which water flows. The interior wings fixed on the interior lateral area lengthwise, vertically and opposing each other are fastened at a certain degree of bending from their position at the water- inlet upto the position at the water- outlet. The interior wings fixed on the interior lateral area of the metal cylinder should be shorter at a certain ratio than the circular radius of water-inlet. In our example, these interior wings are four opposing each other and the short edges of the wings are designed to be 25% shorter than the radius of the circular water-inlet and water outlet. II- The Outer Cover in which the Cylinder Rotates The waterflow entering into the cylinder with a great speed turns the it with a great speed around its own axis thanks to the interior wings fixed in a spiral lengthwise. This motion energy will be transmitted to the various dynamo gears fixed on the metal outer cover in which the cylinder is completely situated. This will be achieved through the gears fixed widthwise in a circle in various rows on the outer lateral area (back) of the rotating cylinder. When the gears fixed widthwise in a circle in various rows on the outer lateral area (back) of the rotating cylinder turn the gears, desired amount of electricity will be produced.

Description:
A SYSTEM TO GENERATE ELECTRICITY FROM WATERFLOW

D E S C R I P T I O N

The field the invention is related to :

This invention is related to the transforming of the kinetic energy produced by powerful sub-flow in the straits into electric power.

The known State of the technique:

The system used for producing electricity from water flow in the world aims at making use of the kinetic energy produced by sub-flows in the straits. This system is applied through only dynamo connected to a known propeller system rotating in the open. However this system was constructed in a very limited way at some certain places for experimental purposes and thus when the intallation costs and the cost-benefit analysis of the electric power to be generated using one dynamo that are not considered sufficient, it was found inefficient, in addition, it is observed that this system is criticized by the environmental organisations because of the fact that the propeller rotates in the open and harms the living creatures in the depth of the sea.

The technical Problems that the invention attempts to solve:

This system that will be used to transform the the kinetic energy produced by powerful sub-flows in the straits and rivers with high flow-rate, is a system composed of a metal pipe placed vertically upstream, and some wings fixed vertically lengthwise on the interior lateral area of a cylinder pipe through which water flows, rather than a system composed of only one dynamo connected to a propeller system.

On the metal part called outer cover in which the rotating cylinder in the system is placed, that is on the back of the cylinder, (on the outer lateral area), a number of dynamoes which are rotated by gears fixed crosswise at various rows are placed. In this system, power is generated on much greater scales by making use of the kinetic energy of the rivers with high flowrate and powerful sub-flows more efficiently.

Because of the the interior wing system in the cylinder, the waterflow passing through the pipe with great pressure rotates the pipe with the same power around its own axis. Thus the gears fixed on the outer lateral area, its back, rotate the series of dynamoes fixed on the outer cover at the same time in a fast and powerful way because of the production of power and speed simultaneously; as a result a continuous and very efficient electric power is generated.

The system set up to accomplish the objective is shown below: The Explanation of the Figures

The Explanation of the Invention:

The system used for transforming the kinetic energy produced by powerful sub-flows in the straits and rivers with high flowrate into electric power. It will be installed on the botom of the rivers where it is deep and narrow, and will be fixed on the appropriate places on the bottom of the straits facing the direction of the current flows in the depth of straits.

The system is composed of two main pieces (1 ,5) which are joined together. The first part is the cylinder system (1). There are four opposing wings fixed on the interior lateral area of the cylinder from the water-inlet to the water-outlet of the pipe. A spiral structure is formed bending the wings at a certain angle (90 degrees in our sample) upto the water-outlet except for the wings at the water-inlet. The short edge of the wings which are rectangular in shape and situated from the water-inlet and water- outlet of the pipe, should be shorter at a ratio of 25 % than the radius of the circular area of the water at the entrance and outlet. The wings that will be fixed lengthwise on the interior lateral area of the cylinder may be at least two opposing each other if preferred. Then these wings can be bent around 180 degrees upto the water-outlet. For instance if 10 opposing interior wings will be fixed, then the location of these wings at the outlet can be bent at 36 degrees from their original position that is, from their location at the water-inlet so, then, the short edges of the wings can be shortened. The total wing bending should be 360 degrees divided by the number of wings.

At the view of the interior wing system of the cylindrical tunnel from the water-inlet (2), wing "a" is situated to the position of "b" at the water-outlet, and likewise, wing

"b" is situated to the position of "c" at the water-outlet; wing "c" is situated to the position of "d" at the wate-outlet; wing "d" is situated to the position of "a" at the water-outlet.

That is, the pressurized waterflow entering into the cylindrical tunnel with a great speed rotates the cylinder the interior wings are fixed on, by applying great preassure on these wings with a great speed and power around its own axis. This rotating power of the cylinder also rotates the gears fixed on the outer lateral area (back) of the same cylinder parallel to each other in various rows with the same speed and power and the gears(4) transmit this power to the various number of dynamoes fixed on the metal outer cover (5) which is the second piece of the system. Thus, it will be possible to generate a great amount of clean and continuous electric energy by making use of the power of water flow in nature.

The metal outer cover in which the rotating cylinder is placed, is also cylindrical (5). The rotating cylinder is not connected to the outer cover at all. The only point at which the rotating cylinder touches the outer cover is the bottom of the outer metal cover because the pushing power which is produced by the rotating cylinder creates it because of the water pressure at the water escape area of the cylinder and of the metal outer cover. The extreme amount of friction caused by the high pressure at the above mentioned touching point must be reduced to minimum so that it does not prevent the rotating speed of the cylinder around its own axis. To achieve this, a few rows of steel balls are placed around the circular base of the metal cover at the touching point; at the bottom of the metal cover where the rotating cylinder will be placed. These balls are placed in the small semi spherical sockets cut in the bottom of the metal outer cover in order to keep them homegenous along with the whole bottom and prevent them to be scattered by the forcing effect of rotation. However, The part of the bottom of the rotating cylinder which touches the balls was covered with diamond, predicting that at the bottom of the rotating cylinder a certain amount of friction will occur because of the friction caused by the steel balls in time (6).

The gears fixed in parallel rows on the outer lateral area of the rotating cylinder transmit the motion energy to the dynamoes by turning the gears of the dynamoes fixed on the metal outer cover. The dynamo gears, will generate great amount of continuous electric energy with the help of the powerful and rapid motion energy produced by the gears of the cylinder.

On the other hand, a funnel shaped steel web (7) to be mounted on the water inlet of the metal cover prevents the stone, rock, alluvial deposits etc.to goi into the cylindrical tunnel with the help of strong water flow from harming the interior wing system. The holes of this steel web must be large enough to let the stones, rock and aluvial deposits that will easily pass through the tunnel but small enough to prevent the larger stone, rock, and aluvial deposits to harm the interior wings and these holes must have a structure so as to resist the entrance of the water at the minimum level. In other words, this stell web will function as a kind of impurity funnel.

Industrial application form of the invention

The system to generate electricity from waterflow so as to successfully solve the technical problems mentioned above is a product to be produced like the other systems.
