The invention is about especially blades having cell structure that is in contact with wind power and can open and close according to the direction of the wind, a switch mechanism that allows these cell structures to open and close and a mechanism and method containing an apparatus for determining the direction to put this switch mechanism in an appropriate position according to the direction of the wind.

PREVIOUS TECHNICS

Today, efforts for obtaining energy from petroleum and similar resources, along with the several issues increasing day by day, are directing the whole world to alternative energy resources.

The leading resources are sun and wind energies. Studies that are based on these two fundamental energy resources showing progresses continuously keep their importance as an alternative to fossil fuel that has got our world on the brink of an environmental disaster.

At present, several systems based on propeller principle such as turbine, air propeller and weather vane are well-known. These work basically with the principle of driven the blades by the relationship of high and low pressures that occurs when the wind collides with blades of the propeller or turbine and as a result, an average of 30% efficiency is obtained. According to BETZ theorem, when the wind speed exceeds 12 m/s, the maximum efficiency becomes 59%. Also, when the speed of the wind goes under 3 m/s then no efficiency is achieved with the current systems.

BRIEF DESCRIPTION OF THE INVENTION

The aim of the invention is to provide a new mechanism that is simpler and more efficient in converting wind energy into mechanical energy and that acquires output even with lower wind speeds (for example 3 m/s).

Mentioned aim is achieved by a mechanism that consists of blades having cell structures that interact with wind power and are able to open and close according to the direction of the wind, a switch mechanism that allows these cell structures to open and close and a mechanism containing an apparatus for determining the direction to put this switch mechanism in an appropriate position according to the direction of the wind.

According to the invention, blades of mentioned mechanism have clearings that are called as cell and preferably in rectangular shape. There are curtains composed of resistant cloth or flexible material that allows benefiting from wind power by occasionally closing cell clearings completely. To manage the contact of the curtains designed to receive the wind in great efficiency with the switch mechanism and thus mechanical opening and closing, curtain shafts are provided on a blade that are positioned on cells generated preferentially by appropriate connection and adhesion manners.

All blades are positioned around the main shaft and one end of mentioned shafts of the curtains is in contact with the curtains on the blades and the other is in contact with the channels opening over inter-connected, preferably cylindrical two telescopic structures composing the mentioned switch mechanism.

Mechanically opening and closing movements of curtains are maintained by rising and lowering on the channels placed opposing on the same positions on both cylinders.

The positioning of the mentioned blade-switch mechanism according to the direction of the wind is provided by an apparatus such as a plate raised by means of a pole from the switch mechanism and thus a vertical wind is received continuously.

The formation and working system of the current invention shall be described in details under ?Detailed description of the invention? title along with the figures explained briefly below.

DETAILED DESCRIPTION OF THE INVENTION

Upper perspective view of the invention is pictured by Figure-1. There are a chassis (16), pedestals (17) standing the mentioned chassis (16) and opening-closing outer cylinder (1) positioned via outer support components (13) on chassis (16). In the center of the mentioned opening-closing outer cylinder (1), there is again an inner cylinder (2). Both cylinders (1-2) are fixed and strengthened with feeders (4). There is a main shaft (7) from end to end on the middle center of the mentioned inner cylinder (2). There are blades (6) in contact with main shaft (7) and preferably more than one blade cells (6.1) on the surface of each blade (6). Also there are outer cylinder (1) allowing the curtains (5) to open and close according to the direction of the wind and the contacted blade (15) determining the direction of the wind. This blade (15) is mounted to outer cylinder (1) by L-shaped shaft. Again there are channels (3-3.1) in the inner surface of the outer cylinder (1) and in the outer surface of the inner cylinder (2), and rollers (5.6) contacted with curtain shafts (5) moving inside the mentioned channels (3-3.1).

By blowing of the wind which is the most important energy during the operation of the system in the direction of a is first of all positioning the inner and outer cylinders (1-2) according to the wind and blades (6) connected to the main shaft (7) are driven by applying force on blade cells (6.1) on the surface of the mentioned blade (6) and the curtains (5) located on these blade cells (6.1). And it starts to turn in the direction of b. Driven blade (6) is opened after approximately 5/2 time and ends the driving. It comes back to its driving location after approximately 5/3 time.

Opening and closing of the curtains (5) in time is provided by the channels (3-3.1) created on the surfaces of inner and outer cylinders (1-2) and rollers (5.6) moving inside these channels (3-3.1). Operation mechanism of curtain shafts (5.1) is described in ore details on Figure-3.

There is a blade (15) determining the direction of the wind connected to a shaft on the outer surface of the mentioned outer cylinder (1). This blade (15) turns the outer and inner cylinders (1-2) that are acting as switching according to the direction of the wind to this direction. Thus, working position of the system is determined whatever the blowing direction of the wind is. Channels (3-3.1) on the surfaces of inner and outer cylinders (1-2) lift the moving rollers (5.6) within 5approximately /2 time. And they pull down them within approximately 5/3 time. They move with an 80? angle while moving up and 40? angle while moving down. Thus, opening and closing of the curtains (5) are realized.

In Figure-2, bottom perspective view of the subjected invention is shown. Turning movement occurred on main shaft (7) is transferred to horizontal conical gear (8) connected to main shaft (7) and the movement on horizontal conical gear (8) is transferred to vertical conical gear (8.1). This movement is given to joint (12) with a shaft, to transmission (10) from joint (12) and then to the load (11). The task of the transmission (10) is to allow the system to work in a round with which it?s more efficient by analyzing the system and determining the torque curve. Furthermore, base ball (7.1) is positioned at bottom end of shaft (7) in order to eliminate the load on main shaft (7). An adjustment screw (7.3) and a chock (7.2) on which this screw (7.3) is located are available for adjusting the base ball (7.1) towards up and down.

In Figure-3, view of curtain (5) mechanism allowing opening and closing of the cells (6.1) on the mentioned blades (6) is shown. Curtains (5) are located to allow the mentioned blade cells (6.1) to open and close. Bearing of the mentioned curtains (5) and opening and closing of them as a fan are managed by helical holes (5.4) created at the edges of the curtain (5) and curtain bearing shafts (5.3) passing through these holes (5.4). The most important factors in opening and closing of the curtains (5) are curtain shafts (5.1) with synchronize movement and the channels (3-3.1) of inner and outer cylinders (1-2) helping this synchronize movement to be happen. The mentioned curtain shafts (5.1) are connected with curtain binding shaft with fixed bottom (5.2) holding the curtain (5) from top and stretching along on it. There are vertical (5.9) and horizontal (5.8) connection shafts connecting both curtain shafts (5.1). Horizontal connection shaft (5.8) connects both curtain shafts (5.1) by reclining. Curtain shafts (5.1) and connection shaft (5.9) are supported from the top by bearings (5.5). Also, main shaft (5.9) and curtain shafts (5.1) are attached to blades (6) on top by the blades (5.7). The reason of mounting the springs (5.7) is to help immediate closing of the curtains (5).

Instructions specifying an application manner described above in details are being given as an understandable example without bringing any restrictions on the current invention. In this example, curtains that have 6 blades with 4 cells on each and are opened and closed via channels within preferably created in two cylinders and angular and other various values relating to these are given.
