Description

VERTICAL WIND TURBINE

TECHNICAL FIELD

The invention relates to a vertical wind turbine that can be installed and operated on coastal edges, roofs, roadsides, open lands, in other words, in any region where there is wind, and that meets the electricity needs of the region by generating electricity.

In particular, the invention relates to a vertical wind turbine comprising a propeller which is horizontally positioned on the casing and rotates under the influence of the wind to generate electricity, and a blade having a concave structure which allows excess wind to pass between them.

KNOWN STATE OF THE ART

The wind turbine is a system that converts the kinetic energy in the wind into mechanical energy and then into electrical energy. Wind turbine generally consists of tower, blades, rotor, gearbox, generator (alternator), electrical-electronic elements. The kinetic energy of the wind is converted into mechanical energy in the rotor. The rotation movement of the rotor shaft is accelerated and transferred to the alternator in the casing. The electrical energy obtained from the alternator is stored by accumulators or delivered directly to the receivers. In order to understand how wind turbines work, important aerodynamic forces must be well known.

Horizontal axis wind turbines are the most widely used and undoubtedly one of the most important turbines among wind turbines. It is probably the turbine that comes to your mind when you think of a wind turbine. Its design is almost identical to the idea used in windmills; the rotor blades, which are attached to a shaft and rotate when in contact with the wind, are connected to a generator that generates electrical energy. It can be likened to a large aeroplane propeller mounted on a tower. Of course, these huge devices are not as simple as a weathervane that we pick up and blow. These devices are turbines that are designed to withstand the destructive effect of wind energy and contain many more complex structures. It has mechanisms that can adjust its direction in the same direction with the direction of the wind to prevent damage in the contrary wind. The casing must also be strong enough to support the weight of the rotor blades, gearbox, generator and other components of the turbine. The cost of horizontal axis wind turbines and other wind turbines is almost the same, although these turbines are the most widely used type due to their efficiency and ability to generate higher power. That's why we mostly see these turbines around us.

The efficiency of the horizontal systems used in the current technique is around 40%, which is quite low. Cost recovery period is long.

As a result, the need for a new economic, useful, practical transport apparatus for solving the above-mentioned problems existing in the existing technique and the inadequacy of the existing solutions necessitated a development in the relevant technical field.

OBJECT OF INVENTION

The present invention relates to a vertical wind turbine, which is developed to eliminate the above-mentioned disadvantages and to bring new advantages to the related technical field, and which meets the electricity needs of the region by generating electricity.

The most important object of the invention is the high efficiency compared to the turbines currently used. While the efficiency of horizontal systems is 40%, the efficiency of our invention is around 55%. The cost of this system is 20% lower than other systems. While the kWh rate in electricity generation is 7-9 cents in others, it is 5 cents in our system. There is no gearbox. Another important object of the invention is that its cost is 20 per cent lower than other systems. Since there is no gearbox in our invention, the cost is lower. While the kWh rate in electricity generation is 7-9 cent in others, it is 5 cent in our system.

The structural and characteristic features and all advantages of the invention will be more clearly understood by means of the figures given below and the detailed description written by making references to these figures, and therefore, the evaluation should be made by taking these figures and detailed description into consideration.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the preferred configurations of the vertical wind turbine are described only for a better understanding of the subject matter and without any limiting effect. Figure 1 shows the vertical wind turbine which is the subject of the invention. Our invention stands out with its maximum and continuous energy intake from the wind due to its design. In the invention, energy is obtained by ensuring the continuity of the thrust force to be applied by the contact surface of the wind energy to the blades (21) of the propeller (20). With the special concave blade (21) design, the direction of the wind angle does not affect the efficiency of the movement. The propeller (20) can reach a speed of 8.8 m/s by taking the first movement in the wind blowing at 2.6 m/s. Electricity is produced by transmitting the rotational movement of the propeller (20) to the generator. In terms of system safety, if the speed reaches more than the desired level, the wind is discharged through the gaps between the blades (21). After reaching a certain speed, the power is stabilised. Wind direction is rendered unimportant in the propeller (20), which is designed and assembled for its horizontal operation. There is no stoppage in the system in the range of 0°-360°. In the invention, a propeller (20) is mounted on the casing (10). Here, the height and diameter of the casing (10) varies according to the project/design and the intensity of the wind. In the propeller (20), the number and design of the blades (21) vary according to the power (kW) desired to be produced. With the connection system (30), the rotational movement produced by the propeller (20) is transmitted to the generator. In this connection system (20 preferably a flanged connection is preferred. By not using a gearbox here, both cost is reduced and gearbox problems are prevented.

The scope of protection of this application has been determined in the claims section and cannot be limited to what is explained above for exemplary purposes, it is clear that a person skilled in the art can demonstrate the innovation in the invention by using similar structures and/or can apply this structure to other areas with similar purposes used in the relevant technique. Therefore, it is obvious that such structuring will lack the criteria of innovation and especially overcoming the state of the art.
