METHOD AND MECHANISM INCREASING THE EFFICIENCY OF WIND ENERGY CONVERSION THROUGH CHANNELING THE WIND

This invention is related to accelerating airflow particularly in energy generation with wind by channeling it by means of one or more sheets, and condensing the same and the method providing conveyance of the accelerated airflow to the desired region of one or more wheels at a desired angle and the mechanism applying this method.

The motion energy that wind has in wind energy conversion systems; motion energy is transferred to a turbine by passing wind on the turbine. The motion energy created in the turbine is transferred to energy conversion units including dynamo, generator and conversion of motion energy to any other type of energy is realized.

Wind energy is defined as the motion energy created by the airflow that creates the wind. The motion energy obtained from wing is used in the field of electricity generation using wind energy. The power plants generating electricity using wind power adapted the logic of windmill that has been used throughout the history to contemporary technology and provide electricity generation by transferring motion energy by means of the mentioned propellers firstly to propellers and then to dynamos, generators from there.

Turbines used in wind energy conversion systems, particularly in systems that provide electricity generating are in the form of wings placed on horizontal plain around a center. Wind is provided to crash wings placed on horizontal plain and give motion to the turbine. Aerodynamic form and placement of wings provides wings to move in one direction upon crash of wind to the wings. In wind energy conversion systems application of turbine expected to rotate by being exposed to airflow has certain defects in it. Rotating motion of turbines need sufficient amount of wind and turbines may not rotate in airflows with low speed. Since turbines that remain in tandem position according to wind direction weakens the airflow of one another, the turbines at the back fail to rotate and this leads to the need of distance between turbines in wind energy conversion plants and for this reason formations spread in broad area and called wind field are needed.

Wind energy turbine is constructed in a form that allows turbine wings have the highest length in order to benefit from airflow. This provides turbine cost to be high. Furthermore, high turbines with large volumes are produced with high costs whereas maintenance administration repair costs are high as well. Wind energy conversion plants having too much volumetric weight create extra costs in the field of transport logistics.

Failure of wind to come ideally from the opposite direction creation of forces in different directions on the wings of wind turbine leads to loss of power in the turbine. In this case, no efficient energy conversion can be realized from the turbine. Creation of loss of power at the stage of transfer of motion energy of wing to the turbine by crashing to turbine wings of wind decreases the efficiency of obtaining energy type different from wind. Turbines used in wind energy conversion systems particularly in systems that provide electricity generation; production costs of turbines in the form of wings placed on horizontal plain around a center is rather high compared to the energy amount they convert. Maximum energy amount that wind energy conversion plants can generate in a year is called capacity factor. An average wind energy turbine can generate theoretically approximately 20-40% of this value according to wind quality. This leads to failure to use the remaining capacities. This invention which related accelerating airflow particularly in energy generation with wind by channeling it by means of one or more sheets, and condensing the same and the method providing conveyance of the accelerated airflow to the desired region of one or more wheels at a desired angle and the mechanism applying this method overcomes the - abovementioned disadvantages fully and it is characterized by providing more efficient motion energy by channeling wind and condensing it in a passage with a cross section area narrower than the entrance and increasing the speed and the wing the speed of which is increased being provided to crash the desired part of the wheel, by isolating other parts of the wheel to the wind excluding the desired region of the wind sheet, its assembly being easy and production cost being low, its ability to operate in wind flows with lower speed as well. Wind is channeled with the wind sheet created and it is channeled to the wheel entrance the cross section area is narrower than the entrance. The narrower gets the cross section area the run of the fluid remains fixed but average fluid speed increases according to continuity equation in fluid mechanics. According to this continuity equation, the speed of wind on a way the cross section area of which created with the placement of the wind sheet increases fairly in the wheel entrance.

Wind the speed of which is increased in the wheel entrance is provided to crash the wheel wings placed angularly on the wheel with desired angle. In this manner the efficiency of transferring the motion energy of the wind the speed of which is increased to wheel is maximized.

Wind the speed of which is increased can enter the wheel only from the wheel entrance determined. The parts of the wheel other than the entrance of the wheel are isolated to wind and access of the air flows created at the opposite of rotating direction of the wheel to the wheel is prevented and creation of power loss is provided. In this manner conversion of the motion energy provided by wind in any other energy type can be performed more efficiently.

With the effect of the wind sheet located in the mechanism created with the invention the wheel can rotate in wind flows with lower speed and energy conversion may be provided. Owing to this, it offers the chance to provide energy conversion even at times and in periods when the speed of wind flow decreases. " Assembly of invention can be realized more easily and production cost becomes lower. The fact that materials used in the invention are smaller than similar ones decreases production cost.

The mechanism created with the invention has smaller volume and occupies a smaller space. Higher number of mechanisms can be placed in wind energy fields created by being aligned one after the other. This invention has been explained in more detail by means of exemplification only with reference to the drawings appended, in those drawings;

This invention which related accelerating airflow particularly in energy generation with wind by channeling it by means of one or more sheets, and condensing the same and the method providing conveyance of the accelerated airflow to the desired region of one or more wheels at a desired angle and the mechanism applying this method is generally composed of wind sheet (1) which provides channeling of wind, its passage from a cross section area narrower than the entrance, wheel entrance (2), the passage point located in the narrowest area of the wind sheet (1) which is the way created with the cross section area narrowed with channeling of the wind, channeling extension (2.1), the part of the wind sheet (1) which provides channeling of wind which inclines inwards from the wheel entrance (2), wheel (3) where the motion energy of the wind is transferred and which rotates from its center around the shaft, wheel wings (3.1) positioned angularly on the wheel (3) and connected to the wheel (3) longitudinally, back cover (4) that prevents turbulences that arise during the exit of wind from the inside of the wheel (3), transmission shaft (5) that provides transmission the motion energy provided during passage of the wind from the wheel (3), generator (6) where the motion energy created in the wheel (3) is transmitted with the transmission shaft (5) and which provides its conversion to electrical energy.

Use of the invention is as follows:

According to the continuity equation, one of the basic principles of fluid mechanics (Q=V.A Q: Fluid run, A: Cross section V: Average speed in the cross section area), run of the fluids remains fixed in the narrowing cross section area and average speed of the fluid increases. According to this principle, average speed of a fluid increases when a fluid with a certain speed is provided to move in a narrowing cross section.

Winds defined as airflows moving in the atmosphere are also defined as fluids with gaseous state and they are characterized with fluid mechanics principles.

There is a wind sheet (1) that receives the wind from the front part of the mechanism created with the invention. The coming wind enters in the wind sheet (1) and the cross section areas moves in an air tunnel as narrowing and while the cross section area gets narrower the speed of the wind increases.

At the end of the wind sheet (1) there is wheel entrance (2) having the narrowest cross section area and where the coming wind reaches maximum average speed. In the wheel entrance (2) the coming wind reaches maximum average speed in the wind sheet (1) and passes to the wheel (3). There is a wheel (3) where motion energy that the wind has by being passed on it which wind reaches maximum average speed in the wheel entrance (2) passing through the wind sheet (1) with narrowing cross section area. Through passing the wind on the wheel (3) the wheel (3) rotates with the motion energy of the wheel. The wheel (3) can rotate around a shaft from the center.

Wind sheet (1) blocks the wheel (3) at the direction of the coming wind. Owing to this the wheel (3) is isolated from the wind and the wind passes to the wheel (3) only through the wheel entrance (2), the desired region. In this case, in the wheel (3), wind coming from different directions, forces that prevent, created by airflows created in the opposite of the rotating direction of the wheel (3) are not created. Efficiency of obtaining energy from the coming wind is increased.

On the wheel (3) there are wheel wings (3.1). The wheel wings are placed on the wheel (3) perpendicularly preferably in the mechanism created in our invention. In our invention wheel wings (3.1) are connected to the wheel (3) with a longitudinal hinge preferably. Since wheel wings (3.1) are connected with hinge they perform opening and closing movement.

There is channeling extension (2.1) in the wheel entrance (2). The wind the average speed of which increases in narrowing cross section area of the wind sheet (1) and which comes to the wheel entrance (2) is channeled with the channeling extension (2.1) which is an extension of the wind sheet (1) and made crash to the wheel wings (3.1) with desired angle. Owing to this, wind is allowed to crash wheel wings (3.1) with an angle closest to right angle if desired and efficiency of motion energy is increased.

There is back cover (4) at the back of the wheel (3). Decreasing the turbulences created during airflow passage inside the wheel (3) prevents the turbulences created when airflow leaves the wheel (3). With the back cover (4) isolation of undesired airflows from the back of the wheel (3) is provided.

There is transmission shaft (5) that transmits the motion energy created in the wheel (3) while the wind passes on the wheel (3). The motion energy transmitted with the transmission shaft (5) is transmitted to the generator (6) and the generator (6) provides conversion of motion energy to electrical energy. Coming wind is channeled with wind sheet (1) and reaches maximum average speed at the wheel entrance which continuing in the cross section narrower than the entrance. With the channeling extension (2.1) located in the wheel entrance (2) wind is provided to crash to the wheel wings (3.1) with desired angle. Upon crash of the wind to the wheel wings (3.1) the wheel (3) starts to rotate. The motion energy created by the rotating wheel (3) is transmitted to the generator (6) with the transmission shaft (5). Conversion of motion energy transmitted to the generator (6) into electrical energy is provided.

Additional mechanisms that provide channeling the wind sheet (1) to the direction of the wind may be placed on the mechanism developed with the invention. For example; placing wing channeling of the mechanism to the direction of the wind may be provided, and using electronic sensors channeling of the mechanism to the direction of the wind may be provided.
