Description

Three-propeller counter-rotating wind turbine
Technical Field
The present invention relates to a three-propeller counter-rotating wind turbine that requires a smaller installation area, yet has higher productivity and increased productivity, does not use gears, and has a direct drive mechanism, as compared to the conventional wind turbines currently used for generating electric power by benefiting from the wind in windy environments.
Background
Energy is described as the ability to do work. Currently, the demand for energy is rapidly increasing due to the ever-increasing economic and industrial activities. Industrial activities have led to the utilization of electrical energy as a primary energy source. Fossil fuels (gasoline, coal, natural gas, etc.) are used in large quantities in energy production.
As fossil fuel reserves are rapidly depleting and the use of these materials is damaging to the environment, old energy production technologies are slowly being abandoned. Carbon dioxide, sulfur dioxide, nitrous oxide, dust and smoke emitted into the earth's atmosphere due to the use of fossil fuels have a great adverse effect on the immediate environment, while carbon dioxide and similar greenhouse gases cause global climate change and pose a threat to the entire world. In the face of these negative effects, research studies on clean and renewable energy sources have begun, and applications have been started to utilize these resources in various fields.
Solar and wind energy are two major clean and renewable energy sources. Solar energy is the cleanest free energy source in use today. With the ever-increasing use, solar energy is now also used for the production of electrical energy, due to recent technological advances, although it was previously used only for thermal energy. The utilization of solar energy depends on the weather and the number of sunny days in a year. Cloudy and cloudy weather limits the ability to benefit from solar energy. This situation reduces the productivity of the solar panels installed to extract electrical energy from the solar energy.
Wind energy is the clean renewable energy source most used following solar energy. Wind turbines mounted to benefit from wind energy rotate with the wind stream created by the wind, and the magnetic field created by this rotational motion can derive electrical energy. The wind turbines currently used occupy a very large installation area, but are not efficient in generating electricity in consideration of the installation area.
One of the reasons for the low production efficiency of conventional wind turbines is the conventional single propeller configuration. In the area where the relevant wind turbine is located, only one propeller benefits from the wind, which results in that the potential wind power cannot be exploited to its maximum. On the other hand, another reason for the low production efficiency is the gear structure for transmitting the rotational motion generated by the wind to the generator, which will generate electrical energy. The kinetic energy transmitted to the generator is somewhat lost due to the gears used in the turbine, and this translates into the production of electrical energy because of the reduction in productivity.
There are several efforts devoted to the operation of wind turbines for harnessing wind power to generate electrical power, and national patent application No. TR2020/05258 describes a "vertical axis wind turbine with improved efficiency". The invention in question is explained as a vertical axis wind turbine with a weight compensating tail system whose eccentric diameter can vary according to the blade width, and said wind turbine is composed of a number of blades, an alternator system, an eccentric motion mechanism providing the transmission of motion between the blades and the rotor or alternator system, an arm connecting the blades and each blade of the eccentric motion mechanism, and a tail.
The national utility model application with the number TR 2020/01184 describes a "high efficiency horizontal axis wind turbine with wide and short blades". It is explained that residential wind turbines are not sufficient in capacity and the related inventions are designed to generate higher electrical energy from lower cost wind energy without the need for secondary masts and other materials to meet all the energy needs of the residence. It is pointed out that the turbine is of the horizontal axis type, the blades are wide and short, and the designed blade surface shows an improved ability to benefit from wind energy.
European patent application publication No. EP3341608B1 describes a "tunnel wind turbine with horizontal axis of rotation of the rotor". The invention is said to relate to a turbine comprising a diffuser in the form of a body of revolution, the wall of which has a shape with a convex-concave aeronautical profile in the axial section, and a rotor with blades rotating in the plane of the throat of the diffuser and connected by their lower ends to a hub.
Another european patent application with publication number EP3121441B1 describes a "rotor blade root assembly for a wind turbine". By way of explanation, the invention relates to a root assembly for a rotor blade of a wind turbine and a method of manufacturing the same. The root assembly is shown to include a blade root portion having an inner sidewall surface and an outer sidewall surface separated by a radial gap, a plurality of root inserts circumferentially spaced within the radial gap, and a plurality of spacers disposed between one or more of the root inserts.
In summary, in order to eliminate the above-mentioned disadvantages and drawbacks of the current technology, developments in the related art have been necessary.
Object of the Invention
The present invention relates to a three-propeller counter-rotating wind turbine developed to eliminate the above disadvantages and to provide new advantages to the related art.
The object of the present invention is to create a wind turbine structure that contains more propellers and blades than the traditional propeller structures of currently used wind turbines and that also transfers the rotational motion obtained from the wind to the generator with a direct drive mechanism.
Another object of the invention is to create a structure that allows to benefit from the potential wind power per unit area at an increased level, enabling a more efficient production of electrical energy, since a wind turbine structure is created that contains more propellers and blades than the traditional propeller structures employed in currently used wind turbines, and that also transfers the rotational motion derived from the wind to the generator with a direct drive mechanism.
Another object of the invention is to ensure a minimization of the costs generated in the production of electric energy, thanks to the formation of a structure that allows to benefit from the potential wind power per unit area at an increased level, thus enabling a more efficient production of electric energy.
The structural and characteristic features of the present invention, as well as all its advantages, will be more clearly understood in conjunction with the drawings given below and the detailed description written with reference to the related drawings, and therefore, it should be evaluated in consideration of the drawings and the detailed description.

Detailed Description
Detailed description of the products to which the invention relates the description of the alternatives chosen is only intended to ensure a better understanding of the subject matter and does not have any limiting effect to some extent.
The present invention relates to a three-propeller counter-rotating wind turbine for obtaining electrical energy from wind in wind-powered environments benefiting from wind, requiring a smaller installation area than the conventional wind turbines currently in use, yet having a higher production capacity and increased productivity, without the use of gears, and with a direct drive mechanism.
The product to which the invention relates generally comprises at least one rear vane cluster (104), consisting of at least five vanes; at least one front blade group (106) consisting of at least seven blades; at least one intermediate blade group (105) placed between the rear blade group (104) and the front blade group (106) and composed of at least nine blades; at least one third rotor (109) linked to the rear set of blades (104) and rotating in a counter-clockwise direction; at least one second rotor (108), linked to the intermediate set of blades (105), rotating clockwise and passing through the third rotor (109); at least one first rotor (107) linked to the front set of blades (106), turning in the counter-clockwise direction and passing through the third rotor (109) and the second rotor (108); at least one contra-rotating generator (103) whose stator is rotated by the first rotor (107) and the third rotor (109) and whose rotor is rotated in the opposite direction by the second rotor (108); at least one propeller housing (101) in which the front blade group (106), the rear blade group (104) and the intermediate blade group (105) are accommodated and rotated; at least one nacelle (102) containing the entire mechanism on its body; at least one tower (100) to carry and lift the entire structure.
The vanes found in the leading vane set (106), trailing vane set (104) and middle vane set (105) preferably have an angle of 60 degrees.
The first rotor (107) and the third rotor (109) connected to the front blade group (106) and the rear blade group (104) rotating by the wind directly turn the stator of the counter-rotating generator (103), while the second rotor (108) connected to the middle blade group (105) rotating in the opposite direction of the front blade group (106) and the rear blade group (104) turns the rotor of the counter-rotating generator (103). The rotational motion of the wind is transmitted to the counter-rotating generator (103) without using a gear system, so that the counter-rotating generator (103) in which the rotor and the stator are directly driven in opposite directions can efficiently generate electric power. Because the number of the front blade group (106), the middle blade group (105) and the rear blade group (104) is large, the wind power can be effectively utilized. Based on these facts, the amount of electric energy obtained per installation area can be maintained at a higher level and the electric energy generation cost can be reduced as compared with the conventional wind turbine.
The number and angle of the blades of the turbine can be varied to adjust the performance of the turbine at the appropriate and desired level based on meteorological data relating to each installation area.
The invention relates to a product which may or may not be fitted with a propeller housing (101).
In another configuration of the present invention, the first rotor (107), the second rotor (108), and the third rotor (109) are disconnected to minimize energy loss, and the front blade group (106), the middle blade group (105), and the rear blade group (104) are directly connected to the body of the counter-rotating generator (103).
