Description:
A WIND TURBINE SYSTEM HAVING A HELICAL SAVONIUS TURBINE AND GENERATING ELECTRICITY WHICH IS MOUNTABLE ON VEHICLES

Technical Field

The present invention relates to a wind turbine system which can be mounted on vehicles and which generates electricity using wind energy, one of the renewable energy sources, while the vehicle is in motion.

The invention relates in particular to a wind turbine system designed to be mounted on the bodies of land, marine or aircraft that need electricity, which can generate electrical energy from the air flow or wind energy generated by the vehicle's movement, and has a helical savonius turbine.

Prior Art

Wind turbine systems used today are systems that convert wind energy, kinetic energy into mechanical energy and then electrical energy. Wind turbines are generally divided into 3 groups as horizontal axis wind turbines, vertical axis wind turbines and inclined axis wind turbines according to the axis of rotation.

Today, systems developed to generate electrical energy from wind energy for land, sea or air vehicles in motion are horizontal axis wind turbine systems that mostly contain wind rose of 3 blades or multi blades. The rotational axis of these systems is parallel to the direction of the wind.

Such systems take up a lot of space. In this respect, it is difficult and costly to locate (install) those systems anywhere on the vehicles, which also deteriorate the aesthetic appearance of the vehicle.

It is not suitable for the systems used in the current technique to operate at high speeds. For this reason, the fact that the vehicle goes above a certain speed poses a danger with the existing techniques. It negatively affects the road holding of the vehicle. They cause excessive energy consumption. They work with sound (noisy).

The systems used in the current art negatively affect the ecological balance harming the flying creatures like birds while the vehicles are on the move.

There are similar wind turbine systems in the literature. One of them is the US Publication No. US5920127A titled “Propeller Wind Charging System for Electrical Vehicles”. In this application, the axis of rotation and wind are parallel to each other. For this reason, since it occupies a lot of space on the vehicle, it is very costly and causes the vehicle not to look aesthetically beautiful. In addition, it causes the vehicle to be swept as it disrupts the aerodynamics thereof. In addition, these systems prevent the vehicle from going to high speeds.

Another application is US Patent Publication No. US20110100731 A1 titled “Perpetual Fuel-free Electric Vehicle”. The invention generally relates to the method used to charge the accumulator on vehicles such as trucks or to produce the necessary electrical energy. The turbine mentioned in this application is installed around the vehicle by opening channels. For this reason, the wind entering the channel hits the turbine inside the vehicle. Therefore, aerodynamics and road holding safety of these vehicles are impaired.

Purpose of the Invention

The present invention provides a new wind turbine system designed to overcome the above-mentioned disadvantages.

In this system, which has been developed to generate electrical energy from air flow or wind energy in land, sea or air vehicles being in motion, the spiral rotation axis in the helical savonius turbine can be horizontal or vertical depending on where it will be mounted. In both cases, however, the axis of rotation of the blades is positioned perpendicular to the wind direction. This allows the wind turbine system to take up less space. At the same time, easier assembly is made with lower costs. As mentioned in the prior art, there is no aesthetic deterioration in its appearance.

Another aim of the invention is to provide a wind turbine system that works without problems even at high speeds thanks to the main blades of helical form and the minor blades of helical form which are inside the helical savonius turbine. There is no reverse force here which negatively affects the road holding of the vehicle. This allows the vehicle to accelerate to high speeds. In this way, no annoying sound or noise is heard while the system is operating. Furthermore, excess energy consumption is also avoided.

In order to realize all the advantages mentioned above and which will be understood from the detailed description below, the invention discloses a wind turbine system which generates and stores electrical energy from the kinetic energy in the air flow (wind (R)) that occurs in vehicles being in motion, comprising:

- a helical savonius turbine which converts the kinetic energy of the wind (R) into mechanical energy, i.e. rotational motion, and comprises main blade shaped in helical form, minor blade positioned to face the back region of each main blade and a camshaft on which said blades are housed,

- an alternator that converts the mechanical energy in said helical savonius turbine to electrical energy,

- a motion transmission mechanism that enables transmission of the mechanical energy in said helical savonius turbine to the alternator.

Detailed Description of the Invention

The wind turbine system (A), which is the subject of the above mentioned invention, has been made in order to most efficiently convert and store the kinetic energy, which occurs in the air flow and/or the current wind (R) in the sea, air or land vehicles that need electricity while they are in motion. The most important element that constitutes the said wind turbine system (A) is the helical savonius turbine (10).

As seen in Figure 4, the turbine rotation axis (X-X) of the helical savonius turbine (10) can be mounted on the vehicle horizontally or vertically, but in any case, the axis of rotation must be perpendicular to the direction of the wind (R), i.e. the direction of travel of the vehicle.

As seen in Figure 1, Figure 2 and Figure 3, said helical savonius turbine (10) comprises at least 2 main blades (11) shaped in helical form and at least total 2 minor blades (12) positioned to face the back area of each main blade (11). Said minor blades (12) are in helical form, just like the main blades (11), and are configured to reduce the loss of efficiency and increase torque during the rotation of the main blades (11). The minor blades (12) in helical form prevent the wind that contacts the backside of the main blades (11) in the helical form from generating reverse force, prevents the loss of revolutions and torque and prevents unwanted current fluctuations in the generated electrical energy.

As seen in Figure 1, Figure 3 and Figure 4, there are wedge-shaped camshafts (13), where main blades (11) and minor blades (12) are positioned, within the helical savonius turbine (10).

As seen in Figure 4 and Figure 5, while the wind turbine system (A) is mounted on the vehicle, the helical savonius turbine (10) is positioned inside the turbine casing (20) by means of this camshaft (13). As can be seen in Figure 7 and Figure 8, a turbine casing (20) can have more than one helical savonius turbine (10), depending on the size of its surface area facing wind, to generate more electricity. Working Principle of the Invention;

- As seen in Figure 5, the helical savonius turbine (10), which converts wind kinetic energy into mechanical energy, i.e. rotational motion, transmits this rotational motion to the alternator (40) with the help of the motion transmission mechanism (30). The motion transmission mechanism (30) can be gearwheel, belt pulley, chain, and the like.

- Alternator (40) is an electromechanical device that converts mechanical energy into alternating current. The alternator (40) converts this rotational motion transmitted by the motion transmission mechanism (30) into electrical energy.

- Said alternator (40) also transmits the electrical energy to an inverter (60) by means of the cable line (50).

- The inverter (60) transmits the alternating current electrical energy to the direct current required to charge the battery (70) and transmits it to the rechargeable battery (70) via the cable line (50).

As a result, the wind turbine system (A) according to the invention generates electrical energy by passing the kinetic energy in the wind and/or air flow through all the above mentioned processes and charging this electric energy in the battery (70) for use when necessary.

In the vehicle where the wind turbine system (A) is mounted, the other units such as the motion transmission mechanism (30), alternator (40), inverter (60), battery (70) and cable line (50), except for the helical savonius turbine (10) which should take the wind (R), can be placed inside the bodywork of the vehicle in such a way that they cannot be damaged by the external factors and they cannot disrupt the external appearance of the vehicle. Said helical savonius turbine (10), on the other hand, can be positioned in various places of the vehicle, for example, above, in front, next to or below, so as to get the wind energy (R) in the best possible way.
