Description

DESCRIPTION OF THE INVENTION

Name of the invention: Winged windmill

Starting from the visual appearance of the invention and comparing it with the existing technical solution to the problem, which this invention deals with, which is the use of wind as a source of energy, I named the subject invention "Winged Windmill". Unlike the existing, predominant and dominant solution of taking over the power of the wind with three-bladed windmills, which decorate our environment more and more every day and threaten our living space, the solution in question is characterized by forms of the same purpose, which, with their appearance and especially their number, justifiably associate with the mentioned name. Instead of only three propellers, the proposed solution is characterized by the mass of the mentioned wings, the number of which exceeds several hundreds.

Of course, it is not only a question of the external appearance of the technical solution to the problem, but first of all the question of the efficiency of such a solution in relation to the excessively high price of their products according to the existing solutions.

The details of the solution will be discussed in more detail in and under the headings of the following description.

Technical field to which the invention relates

The invention relates to the technique of obtaining energy. Given the different sources of energy, the techniques for obtaining it are very diverse. In addition to limited resources, the technique of burning fossil fuels and biomass leaves undesirable consequences for the environment, and this technique can lead to (according to the opinion of many scientific authorities) climate changes with uncertain consequences.

Unlike the previous one, the technique of obtaining energy using wind power is based on clean and renewable and sometimes abundant sources and has no harmful and unwanted consequences for the environment as well as climate change with an uncertain outcome.

Prior art

Despite the large number of sources and the application of the latest scientific solutions in obtaining energy from these diverse sources, the amount of energy obtained does not even remotely meet the growing and increasing needs, both production and final consumption needs. When it comes to using the power of the wind, the existing technology knows various types of windmills, which use the wind as a spontaneous natural phenomenon with a very uneven power and irregular and even in some places very rare occurrence. In addition, the technique of taking over such an uneven force and irregular natural phenomenon, such as wind, is extremely irrational and is reflected in a very low percentage of the use of the surface of the impact force of the wind, which is described by three or four propellers of the windmill. Instead of 5 to 6%, which is covered by three or four propellers in the existing system, by applying the solution according to the subject invention, this percentage is up to ten times higher.

The essence of the invention

The essence of the invention is reflected in a more rational use of the surface of the impact force of the wind, which is covered by the propellers, in this case the wings, of the rotor of the windmill.

For me, the explanations, how a larger number of propellers does not achieve a higher speed of their rotation, as if the goal is only speed and not total power, which, in addition to speed, also consists of mass, are unacceptable to me. So, for example, it is not the same to lift 100 kg one meter in one second or 200 kg one meter in the same time. In the first case, the power is one kilowatt, and in the second, two kilowatts. And when we have the power, then it will not be difficult for us to reach the desired speed with the appropriate transmission.

Or, for example, in the study for the construction of a wind park in South Banat, the information is presented, how in the case of windmills with the maximum performance of the propeller length, the effect changes drastically, namely at a wind speed of 3m/s 20 KW, at a speed of 6m/s 600 KW and 12m/s 3000 KW, but I did not find an explanation other than the term drastic, which would explain such a drastic change.

It is obvious, however, that in addition to the speed, mass also participates in the force of the wind, whose change, i.e. increase, occurs due to the higher density of the air during its faster movement. If, however, there is no problem with converting the wind speed into the rotation speed of the windmill rotor, which would then also depend on the type of converter, then the effect of the wind speed on the power obtained should be proportional to that speed, and everything else, in one way or another, would have to be related to the mass, if the power formula in which mass and speed are equal factors is not questioned.

What is certain, however, is the fact that, in this case, there is no speed without mass.

If, however, we accept the claims of a proportional relationship between the surface of the impact force of the wind, and the force of that wind itself, then the advantage of a winged windmill over a three-bladed or similar one is incomparable, since the comparability of those surfaces, which we will prove computationally in the following presentations, shows that this advantage is tenfold or even more than that, and thus the greater efficiency of the device, and thus the lower price per unit of product.

In the aforementioned detailed and comprehensive study, prepared by experts invited for this purpose, the rarity of wind speeds exceeding 3m/s, as the minimum required to start windmills built according to the most modern technical solutions, is presented as a problem. This invention also solves that problem, so that starting windmills will be possible even at lower wind speeds, in proportion to the mentioned greater degree of rationality of using the surface of the impact force of the wind, and thus achieving a higher total power, which can be converted into the desired higher speed, which is limited as the smallest usable speed, by appropriate speed transmission.

The special specificity of speeds, which are achieved based on the speed of wind movement, is that they are very often limited by low speeds, on the one hand, and on the other hand, by frequent changes of such and such speeds. It is my conviction that this issue, with this invention of mine, is solved in a more efficient way than the existing solutions.

In addition to the mentioned low level of utilization of the surface of the impact force of the wind, it is obvious that modern windmills are also burdened by the problem of rotor suspension, or as I have already called it the converter of the rectilinear movement of wind energy into rotating energy, and the associated existence of other limitations, which is solved in a new way with my invention. This new solution is reflected in the introduction of a movable base with a rotor suspension on both sides. With this new way of hanging the rotor, some new possibilities for improving the efficiency of the entire device have opened up, which will be explained in more detail later.

Description of the draft images

Figure 1. is a pictorial representation of the appearance (part) of the converter of rectilinear air movement into rotational movement.

Considering that it is an explanation of the working principle itself, only one quarter of the rotor is shown as sufficient for that explanation. The rotor of this converter (in order to understand its functioning) is comparable to the rotor of some of the existing and prevailing three-propeller windmills, in that instead of the propellers there are rotor wings, which (instead of 5 to 6% of the existing windmills, of the size of the rotor surface to which they relate) rotated by 45 degrees, cover up to 70% of the imaginary surface of the rotor, as the surface of the impact force of the wind.

The image represents the rotor of the converter placed in a vertical position with a graphic representation of the radial and circular division, which in the end shows the imaginary surface of the rotor, which is covered by only one wing. In those fields, a pictorial representation of the wings related to that imaginary surface of the rotor is given. Of course, the shape and surface of the wing, in practical implementation, does not have to correspond to the imaginary surface of the rotor, but the surface of the wing itself can be close to that surface.

The best idea of the position of the wings in the rotor is obtained when observing their row in the rotor in a horizontal position, as they are presented in the first picture. Viewed in a horizontal position, the wings are located one above the other, rotated by 45 degrees in relation to the straight air movement, in a radial position, as shown by the radial division lines of the rotor.

From the example shown, it can be seen that the inverter rotor is divided into five circles in which the rotor wings are arranged. In the first circle, closest to the center, 8 wings were overlooked, with only one wing shown in the picture, which is marked with the number 1, in the second circle, 16 wings were overlooked, of which only two wings were shown, which were marked with the numbers 2/1 and 2/2, in the third circle, 32 wings were overlooked, of which only two were marked with the numbers 3/1 and 3/2, and in the 4th and 5th circle 64 wings, of which only two are marked with corresponding numbers.

The first picture does not show the complete frontal view of the rotor with, as I called them, joint and inter-joint couplings, for the sake of clarity. For this reason, a special representation of these rotor elements is given in the second and third picture, which, I believe, due to the simplicity of the device as a whole, will not be difficult to imagine in the whole system and its functioning.

Figure 2 shows what I have called a hinge joint. The connection of one wing from the previous circle with two wings of the next circle is shown. This coupling should provide both the spacing and the rotated position of the connecting wing. This position is ensured by the corresponding points on the hinge joint, which determine the distance and position of the wings. The incoming wing is marked with Roman numeral I, while the outgoing wings are marked with Roman numerals II and III.

The Arabic numerals 1 and 2 are the screws that connect the outgoing wing II, the numbers 3 and 4 the screws that connect the incoming wing marked with the Roman numeral I and the screws 5 and b that connect the outgoing wing marked with the Roman numeral III.

It is logical to conclude that the width of the incoming wing, at the end of the wing itself, corresponds to the sum of the widths at the beginning of the outgoing wings, which is a matter of the very geometry of their distribution on the imaginary surface of the rotor.

Due to its location and the function it has in the system, the shape of the joint coupling is determined to be aerodynamic. In practical implementation, it is enough to maintain and support its aerodynamic shape.

Figure 3 shows an inter-joint coupling represented by one (for aerodynamics) modest shaft, with appropriate slots and openings for connecting it to the ends of the joint couplings through holes 7, 8, 9 and 10, marked on the joint coupling, with the aim of connecting the entire system into one unit. Figure 4 shows the mobile stand, on which the rotor with protruding rings for tying the stabilization wires is graphically depicted. The number 1 is the movable or rather the rotating foot of the base, the numbers 2 and 3 the supports on the outlet side and the number 4 the support on the air, i.e. the wind, inlet side, the number 5 is the bearing rotating shaft of the rotor, the numbers 6 and 7 are the stabilizing wires and finally the numbers 8 and 9 are the protruding rings for attaching the stabilization wires.

Figure 5 shows a tunnel or channel, which wraps around the rotor of a windmill. The number 1 is the rotary shaft, the number 2 is the foot of the mobile stand, the number 3 is the rotor supports on the output part, and the number 4 is the support on the wind input part. The number 5 is the rotor with stabilizing wires, the number 6 is the conical cover, the number 7 is the rim of the channel itself, and the number 8 is its extended part.

Detailed description of the invention

From the previous description, we could see that this invention called "Winged Windmill" is very different from the existing solutions in its external appearance, primarily in the external appearance of the rotor, i.e. the converter of rectilinear air movement into rotary motion, and then also in the technical solution of its two-sided suspension on a movable, i.e. revolving base. However, the change of this external appearance represents at the same time an essential difference in relation to the existing solutions. That difference is reflected in its much higher efficiency, that is, in a much larger amount of energy produced with unchanged or proportionally significantly lower investments. The essential change, in relation to existing solutions, is reflected in a significantly larger surface area of wind shock power taken over by the converter of that straight-line energy, in relation to existing solutions.

The converter is a system of interconnected wings, which represent the imaginary surface of the rotor, divided into the appropriate number of wings, rotated by 45 degrees in relation to the direction of air movement. An example of such a division is shown in Figure 1 of the drawing. In the example, it starts from one ring on the common shaft, whose radius is 1.5 m, and then from the first circle, from eight wings, whose length is also 1.5 m. Under the aforementioned assumption that these wings cover the imaginary surface of the rotor, we come to the conclusion that these eight wings cover an area of 21.20 m2 or 2.65 m2 per one wing of the appropriate shape. Each of these wings splits into two wings in the next round, so that in the next second round we have 16 wings, each 3 m long, which cover the imaginary surface of the rotor of 84.78 m2 or 5.30 m2 per one wing of the appropriate shape. Following the front one, in the third circle we have 32 wings, also 3 m long, which cover the imaginary surface of the rotor of 141.30 m2 or 4.42 m2 per wing of the appropriate shape. In the fourth round, we get 64 wings according to the same principle, which cover the imaginary surface of the rotor of 197.82 m2 or 3.09 m2 per one wing of the appropriate shape, and finally in the fifth round, also 64 wings, since there is no bifurcation, due to a smaller change in the imaginary surface of the rotor and the same number of wings, which cover it, and whose area is 254.34 m2 or 3.97 m2 per one wing of the appropriate shape shape.

In the forward way, we arrived at the total area of the rotor blades in all five circles of 699.44 m2, which is the imaginary area of the rotor (without the surface of the ring on the shaft), which we divided into a total of 184 rotor blades, of different shapes and different areas per circle. Rotated 45 degrees to the direction of the wind, these wings cover about 70% of the imaginary surface of the rotor, which is far more than the area covered by three or four propellers in a windmill.

The given example of covering the surface of the rotor with wings is only an example and is not binding in any case, on the contrary, in practical implementation a smaller, but not significantly smaller percentage of that coverage is implied.

All wings are connected to each other with hinged joints fig. 2. and inter-articular connectors fig. 3., so that they form a single unit. In addition to this, the ends of the wings near the central part are specially stabilized with appropriate wires, like those of suspension bridges and tied to enlarged and protruding rings, in front of the respective wings, on the rotor shaft. Thus, we have eight wires that connect eight wings in the first rotor circle, sixteen wires that connect sixteen wings in the second rotor circle, thirty-two wires that connect thirty-two wings in the third rotor circle, sixty-four wires that connect sixty-four wings in the fourth rotor circle, as many as there are in the fifth circle, which makes a total of 184 wires, as many wings as there are in the rotor example shown in Fig. 1.

It is necessary to install stabilization wires at the rotor outlet due to the swirling of the wind.

I also consider it necessary to mention that the bearing elements of the wings in the first round should be specially strengthened, since they take the entire power of the rotor and transfer it to the rotating shaft.

The hinge joint (fig. 2.) connects one wing from the previous circle with two wings in the next circle, ensuring at the same time the angle of inclination of the wings according to the movement of the wind. All elements of the joint coupling are aerodynamic, which should be taken for granted. The wing from the previous round is marked with Roman numeral I, and the wings in the next round are marked with Roman numerals II and III. Arabic numerals from 1 to 6 indicate the places where the wing joins the joint. At the end of the fourth and fifth rounds, the appropriate adjustment of the joint couplings would be made, as is the adjustment necessary for each round.

The inter-joint joint (fig. 3) consists of one aerodynamic or flattened shaft with appropriate slots at the ends of the shaft, through which joint joints are connected so that the rotor of the energy converter of rectilinear air movement into rotational energy forms a single unit.

Figure 4 shows a mobile stand that provides the possibility of hanging the rotor on both sides, which achieves its significantly greater stability compared to existing solutions.

Fig. 5. shows a tunnel that includes the rotor, thus directing the movement of the wind towards the rotor, and then, with its bell-like expansion at the entrance, capturing larger amounts of air, which represents additional possibilities and therefore an advantage compared to existing solutions. Installation of such tunnels is most suitable for small-scale windmills.

In addition to this, there are additional possibilities in placing a conical cover on the central part of the mentioned channel, which directs the air, i.e. the wind, towards the peripheral parts of the rotor, which also gives increased results. This conical cover is connected to the outer channel, so it moves simultaneously with that channel, orienting towards the direction of the wind, while the rotor rotates independently of this cover in the direction dictated by the direction of the wind.

Method of applying the invention

The only or almost the only and exclusive way of industrial or any other application of a winged windmill is to enable the production of electricity of appropriate power with the help of an electric generator, in order to satisfy both industrial and other needs of its consumption.
