Abstract

The intensive activity for the more powerful, cleaner, renewable and profitable power sources directed us towards a completely new construction of wind turbines. The wind turbine in the combined nozzle is a new electro energy facility, which converts the long term weaker "free" flow of air into the "concentrated" and "regulated", thereby increasing its power and productivity multiple times. The increase in wind speed, and consequently in power, occurs when the turbine rotor is built in the neck of the combined nozzle. Greater power on the turbine comes from the cube of doubly elevated speed on the rotor, and the decrease of exit speed in the diffuser. Wind turbines in the combined nozzle can be of swerving and fixed construction, and of small, medium and large power with the appropriate regulation system. However, the sloped lower collector surface of the combined nozzle is very suitable for the installation of photo-voltaic solar panels, and the swerving mechanism of the wind turbine, with the aid of a special program, can successfully follow the movement of the sun. So, the same facility can very profitably produce energy from the wind and the sun. If the fixed wind turbines in the combined nozzle are installed one next to the other, the result is a wind shield, which protects the lee, and can produce very large quantities of electrical energy, which fact is suitable for the surrounding area of Senj, where approximately 90% of energy comes from the north-eastern winds (bora).

Description

WIND TURBINE IN A COMBINED NOZZLE

DESCRIPTION OF THE INVENTION

Area of the invention

The wind turbine in a combined nozzle with the flow concentration and regulation is intended for the production of electrical energy especially from long-lasting weak and medium winds; from all directions, in case of the swerving construction, and from one direction only in case of fixed mounted installations. The windbreak is a series of wind turbines installed fixedly one next to the other whereby simultaneously producing electrical energy and protecting objects in the lee. This new technique belongs to the area of wind turbines or wind generators, that is to the technique of using wind energy and is part of group F 03 D 1/00 «Wind powered actuating mechanism with a rotational axes mostly in the direction of the wind» according to the International Classification of Patents.

Technical problem

Wind, as a clean and renewable energy source has a serious short coming, and that is the low profitability in zones with lesser potential, if existing wind turbines are used. The wind turbine in a regulating nozzle of the combined mantle is a new energy facility, which turns the "free" flow of air into the "concentrated and regulated", whereby multiplying its power, productivity and profitability multiple times. This increased power comes from the cubes with higher speeds and mostly from medium and weak but constant winds ( P = ( v³ )).

In case of turbines in a nozzle of a combined mantle, the speed at the neck would approximately double, which fact would create certain problems in cases of stronger north-eastern (bora) and southern winds. That is why it is necessary to install aerodynamic swerving flaps at the entry front lower part of the nozzle, which would automatically open and pass the excess air mass inactively outside of the rotor and thereby regulate the increase in speed in the nozzle neck. In wind turbines with a swerving construction, which have a flap rotation mechanism, the power regulation can be achieved by rotating the mantle axis away from the direction of high winds, with the same device aided by wind speed and direction sensors, and computers and operative programs. State of the art

Wind energy has been used around the world for a long time to power ships, mills, pumps or generators. The best known of these machines is the propeller drive with two, three or more blades mounted vertically on top of a pillar, with the possibility of turning in the direction of the wind action.

However, all of these devices operate in the free stream of the wind. The wind turbine, which would be installed into the regulating nozzle of the combined aerodynamic rotational mantle and the supplementary collector surfaces haven't been realized until now.

Exposition of the essence of the invention

The increase in wind speed, and consequently the increase in power, occurs when the wind turbines rotor is built in the neck of the aerodynamically profiled nozzle mantle, which is constructed in segments of circular cross sections like the front upper part of the aviation profile. This rotationally constructed part of the aero profile as nozzles induces a big increase in the radial, and thereby the resulting overall speed.

Under pressure side (the hump) of this truncated aero profile is turned toward the center of the nozzle, and lift in each place is directed radially centripetally, which fact (because of the under pressure) involves a large number of streamlines in the active air mass.

After that, a centrifugally directed reaction force appears in the stream flow, which, helped by the diffusers behind the rotors, results in a significant widening of the stream field, and the reduction of speed. This form of a short aerodynamically profiled nozzle enables the increase in the flow speed. The elevated speed in the rotor plain in the nozzle neck then gives an elevated flow of air mass, and the supplementary sloped collector surface on the lower front side considerably aids in that. More power in the turbine comes from the augmented flow of air, which creates higher speeds on the rotor blades, as well as from the significant reduction of that speed in the diffuser behind the rotor. Theoretically, in the section of the work area the power of the wind turbine rises with the speed cube, i.e. Psf(v³) and for those in the nozzle it would be much more P≤f(2v)³, and time wise would take longer, because of the usage of even weaker winds with the elevated speed on the rotor.

The increase in speed at the neck of the nozzle (vs) opposed to the surrounding wind speed (vo) is approximately vs= 2vo. Such elevated speed would, in a certain work area, give elevated theoretical power according to the formula P= vs³ = 2 (vo) ³ = 8

VO³.

The increase in wind speed in the nozzle vs= 2vo, enables such a wind turbine to operate over a significantly longer period. Namely, wind turbines operate poorly or not at all at speeds under 5 m/s, and the nozzle elevates them in higher working speeds thereby prolonging the drive time.

And the multiplication of increased speed and longer working time gives 3 to 4 times more electrical energy.

The wind turbine in the nozzle with the combined asymmetric mantle is a facility, which consists of a curved mantle surface of the aerodynamic nozzle neck and front lower elongated sloped piece (the supplementary collector mantle) made in segments with flat surfaces, with a specific pitch. This kind of a combined nozzle mantle with part of the lower flat collector surfaces is much simpler and cheaper to manufacture, as well to use. The overall weight of the combined nozzle is considerably smaller. The wind speed moment on the mantle is also reduced. The regulation of the increase of flow speed in case of high winds is significantly facilitated by the installation of swerving regulation flaps on the lower flat surfaces.

The wind turbine with a combined asymmetric mantle is appropriate for both fixed and swerving construction of facilities of small, medium and high powers.

It is especially favorable for the construction of wind shields, i.e. the installation of wind turbines of fixed construction in rows one next to the other or even one above the other. This is possible when most of the energy, approximately 90%, comes from the north-eastern winds (bora).

Such wind shields can produce significantly more electrical energy, and ensure good protection of structures and settlements in their lee.

The lower sloped collector surface of the swerving nozzle of the combined mantle is favorable for installation of solar photo-voltaic panels, which would enable (in the same facility) the successful production of electrical energy from two renewable sources: the wind and the sun. This is important for the operation of transmitters (and others) outside of the electrical systems, because of the relation between the sun and the wind, that is between summer and winter.

Such a facility would be very profitable not only because of the production of double the quantity of electrical energy (wind plus the sun) but also because of the fact that the same swerving system of the wind turbine along with the special calculation program would be used also for the optimal orientation of the solar panels, thereby insuring a sizeable saving in investments and maintenance.

Short description of the drawings

Pic. 1 and 2

Picture 1 shows the front view, and picture 2 the side cross section of the wind turbine in a combined nozzle with the swerving construction. These pictures show the essence of the invention. These pictures, as well as the following ones have these assigned markings:

1. Wind turbine set with the rotor, generator, etc.

2. Profiled wind turbine bearings located in the zone of the exit diffusers.

3. Short aerodynamic nozzle mantle - inner side, and the bracings on the outer side, all together made up of 12 circular segments.

4. Front, lower, sloped (slope of 30° to 38°, middle 34°) supplementary collector mantle in seven segments of flat surfaces joined on the short aerodynamic nozzle neck mantle which all together make up the combined nozzle.

5. Exit diffusers. Fabrication and location in several options. 6. Electromotor powered swerving mechanism for the optimal orientation of the combined nozzle toward the wind (or toward the sun in the summer if solar panels are installed).

7. Reinforced axially-radial bearings (ball or tube) with a large gear for the action of the swerving mechanism.

8. Bearing column, which can be made in several variations: tubular or grid-like. Materials for the column can be steel or specially reinforced concrete with rust- resistant steel wire, 0,6 to 0,7 mm thick, unkempt like wool, blended into it. This kind of concrete even has the advantage to steel because, for the same strength, it is lighter, cheaper, and without the expensive anticorrosive protection.

Pic. 3A and 3B

Picture 3A (front view) and picture 3B (longitudinal cross section) show the installation of solar photo-voltaic panels into the wind turbine facility in the combined nozzle, with the swerving construction.

The marking (9A) shows the solar panels. The lower sloped surface of the collector, angled at 38°, is especially appropriate for the installation of these panels.

The installation of the solar photo-voltaic panels for the production of electrical energy on the wind turbine facility in the combined nozzle with the swerving construction is a big save because of the already installed expensive mechanism, which has to continually and optimally turn the panels toward the sun.

Pic. 4A and 4B

Picture 4A (front view) shows how the collector surface in the front lower part can be expanded and thereby collect and increased air mass, which would be able to increase speed in the nozzle neck up to 2,5 times.

Pictures 4A (front view) and 4B (longitudinal cross section) shows the cheaper wind turbine of less power in the combined nozzle with the swerving construction but without the electromotor and the rotation mechanism.

The maintenance of the wind turbine in the direction of the maximal wind action is enabled by the two stabilizer surfaces (marking 9B) located in the lee. As soon as the wind turbine rotates away from the direction of the wind, a force acts on the stabilizer surfaces, which in turn creates a moment and everything again returns to the direction of the optimal stream. Only one reinforced bearing (marking 9C) of the generator with the rotor blades is enough for the small, cheap wind turbine without a diffuser

Pic. 5 and 6A and 6B

Pictures 5 (front view) and 6A (longitudinal cross section) show the wind turbine in the combined nozzle with the fixed construction.

This kind of construction is significantly simpler and cheaper, because it does not have and axially-radial bearing and the swerving mechanism, and the tubular bearings (marking 10) are easier to fabricate and install.

To be able to see the application possibilities, the sloped collector mantle in segments is slightly longer. This enables a higher concentration on a larger surface in the nozzle neck and an increased wind stream speed, 2-3 times to the surrounding one. The lower collector surface is mounted at an angle of 38° in relation to the horizontal one to achieve a more favorable pitch of the bearing. The fixed wind turbines in the combined nozzle are appropriate for those areas (e.g. the region around Senj, Croatia) where most of the winds, over 90%, comes form one direction, the north-east. These kinds of wind turbines with the fixed construction are used for the construction of large energy systems in the form of wind shields. Picture 6B (front view) depicts the wind shields, i.e. the row of wind turbines in the combined nozzle, with the fixed construction installed one next to the other.

Pic. 7 and 8

Picture 7 (front view) and 8 (longitudinal cross section) show the wind turbine in the combined nozzle with a special fixed construction. It differs from the wind turbine in pictures 5 and 6 in that the front lower collector mantle is mounted on the underside, but only half of it. The other half of this mantle (5 segments) is mounted on the upper side with the reinforcement of the construction itself.

This is done so that another wind turbine in the combined nozzle with the fixed normal construction could be added on top of this construction.

This two-piece collector mantle can also be installed horizontally, i.e. rotated by 90°, in the special construction.

Pic. 9, 10A and 10B

Picture 9 (front view) and picture 10A (longitudinal cross section) offer the view to a double module, with the fixed construction, which consists of a wind turbine in the combined nozzle installed one above the other, of the same width.

The upper wind turbine is of a standard construction with a sloped collector mantle in the lower part, while the lower one is of the reinforced and special construction with a symmetric collector mantle, i.e. half up and half down, like in pictures 7 and 8.

The combined nozzle of the lower wind turbine is simultaneously a bearing of the double high module.

Picture 10B shows the wind shield from the front arranged partially from double modules with wind turbines in the combined nozzle. The wind shield with the installed double modules one next to the other would provide a lot of power and good protection of the area in its lee.

Pic. 6B and 10B

Picture 6B offers the front view of the wind shield, i.e. the series of wind turbines in the combined nozzle (like in picture 5) installed one next to the other on a hilly terrain. The collector mantle, the aerodynamic nozzle, and the exit diffuser enable this construction in places where most of the wind potential is coming from the same quadrant, like around Senj in Croatia (that is in the wider area from Maslenica to Bakarac). The wind shield offers a series of advantages in the technical and economic sense, i.e. more power, cheaper installation, easier maintenance and better protection of the structures in lee.

Picture 10B shows the complex wind shield. Double modules (pictures 9 and 10A) of great height and power are installed in the middle part in the valley, which cover the area well, and on the surrounding hills, there are normal, that is single wind turbines in the combined nozzle like in pictures 5 or 6B. The complex wind shield - electric power plant, and especially its double modules, could provide considerably more of the clean, renewable and cheaper electro energy, as well as better protection against strong north-eastern winds (bora), which there is more and more due to the climate change. Pic. 11 , 12 and 13

Pictures 11 (front view), 12 (longitudinal cross section) and 13 (layout) show the wind turbine in the combined nozzle with the swerving construction, with the altered collector mantle and the system of flow regulation by swerve, in layout.

Due to this regulation, the mantle is narrowed towards the bottom, has 7 segments, and the flat surfaces have a different configuration. The pitch of the lower surface is at an angle of 38°.

A stronger swerving mechanism drive is provided due to the higher speed. The system needs to also have: wind direction and strength sensors, and a computer which automatically activates the servomotors when the speeds of the high winds exceed the programmed sizes. Then the servomotors rotate the combined nozzle, and it gets a smaller amount of the driving air mass so the speed no longer rises.

When the wind speed lowers again, the servomotors return the nozzle in the position toward the wind and the turbine again gets a larger air mass, i.e. a higher or more productive speed.

This system of regulation is not possible with the fixed mounted wind turbines in the combined nozzle and with small turbines without a swerving mechanism and servomotors.

Pic. 14, 15, 16 and 17

Picture 14 offers the front view of the wind shield in the combined nozzle with the swerving construction and shows the positions of the regulation flaps and thrust resistor surfaces in the special construction, according to the sequence of markings:

12. Lower, first regulation flaps of the collector mantle (2 pieces)

13. Upper, second regulation flaps of the collector mantle (5 pieces)

14. Direct, thrust-resistor flaps, under the force of the wind open the first regulation flaps

15. Indirect, thrust-resistor flaps, under the force of the wind open the second regulation flaps

Picture 15 shows the position of the regulation flaps in the longitudinal cross section.

In picture 16 there is the detail of the direct thrust-resistor surface (14) which under the force of the wind opens the lower, first regulation flaps (12). The return spring, with the marking 16, automatically closes the regulation flap (12) once the wind dies down.

In picture 17 there is the detail of the indirect thrust-resistor surface (15) which under the force of the wind opens the upper, second regulation flaps (13) by way of a steel line (18). The return spring (with the marking 16) automatically closes the regulation flap (13) once the wind dies down. And the second return spring (marked 17) automatically returns the thrust-resistor surface (15) into the starting position in low winds.

These pictures, 14, 15, 16 and 17, show the automatic regulation of wind flow, through the regulation flaps by way of the wind pressure force directly or indirectly mechanically without the use of expensive servomotors, sensors and computers.

Pic.18

Picture 18 shows the air flow regulation system, i.e. the flow speeds in the neck of the combined nozzle in both the swerving and with construction with the action of the wind on the thrust resistor surface (15) and the hydraulic transfer of force for opening the regulation flap, according to the marking as follows:

19. Pressure hydraulic cylinder driven by the thrust of the wind on from the resistor surface (15)

20. Hydraulic connecting pipe for the pressurized oil

21. Working hydraulic cylinder for driving the regulation flap

22. Return spring for returning the regulation flap.

This picture shows the automatic air mass flow regulation by way of the regulation flap (13) and the force of the wind's thrust, similar to picture 17 indirectly and hydraulically, without the expensive sensors, computers and servomotors, and it is appropriate for facilities of born small and high power.

Pic. 19 and 20

Picture 19 shows the air flow regulation system in case of stronger winds for wind turbines in the combined nozzles of both the swerving and fixed construction, by way of sensors, computers and servomotors (marking 23) which automatically opens and closes the regulation flap (13) following a program. The system is appropriate for wind turbines of medium and high power.

Picture 20 shows the special exit diffusers (marking 24) on the protective wind shield, which have the task of dispersing the air mass downwards in case of smaller wind speeds (for extra power) and in case of high winds they direct the air mass upwards for better protection of structures and settlements in lee.

Description of the realization of the invention

There are two appropriate ways of realizing this invention. The recommended one is to build a prototype of smaller power and with the fixed construction to minimize costs.

1. Working documentation must be made, following the attached pictures, and the necessary calculations, and according to this documentation the nozzle of the combined mantle is to be made, and a suitable wind turbine, readily available, needs to be installed into it. All of this then has to be installed onto the necessary bearing columns.

A standard wind turbine (without a nozzle) of the same power should be installed at a favorable location in the proximity of the new wind turbine in the combined nozzle, and simultaneously measure the amounts of produced energy of one turbine and the other (with same winds). Other important parameters should be measured on the prototype, like the wind force moment, performance of the regulation system, etc. After making the prototype, the zero series would be made, etc.

2. Following the attached pictures from the patent application, technical documentation of the prototype model should be made, and then the corresponding model. All this should be tested in an appropriate wind tunnel, and only afterward should the prototype itself be built. This other way is considerably more complicated, more expensive and more time consuming. Method of application for the invention

The wind turbine in the combined nozzle is a new electro energetic facility for profitable production of electricity. Its basic purpose is to (in the same conditions) produce 3 to 4 times more electric energy, then the standard turbines of today (without the nozzle), for the same rotor diameter and at the same height. They can be made for small, medium and high powers of 3 kW to 3 MW, and their construction can be swerving and fixed. They have several regulation systems for the increase of wind speed and power. Solar photo-voltaic panels can be installed onto the special wind turbine in the combined nozzle to produce electric energy from the sun.

Wind stream on the turbine in the mantle of the combined nozzle does not affect the other stream in the neighboring nozzles so they can be installed on next to the other without a problem as one wind shield, or wind shield - power plant. This can be successfully constructed with wind turbines in the nozzle with the fixed construction where 90% of the wind energy always comes from the same quadrant, like the northeastern winds (bora) in Croatia, in Senj. This kind of a facility could produce a large quantity of electrical energy and ensure adequate protection (of all structures) from the gusts of bora in lee of the wind shield in question.

Wind turbines in the small power nozzle (swerving or fixed) would be a great choice for weekend-tourists, isolated homes, agricultural properties, relay systems, etc. The most interesting for them would be the wind turbine in the combined nozzle mantle with solar photo-voltaic panels for the production of electricity from the sun during the summer, and from the wind during the winter.

Wind turbines in the combined nozzle of medium power could successfully ensure electrical energy even for larger consumers. These wind turbines could work independently or be part of a grid. Wind turbines of high power would be swerving or fixed, with or without the photo-voltaic panels. Those installed as a farm or a wind shield - electrical power plant should in most cases be included in the electro energy grid.

The new wind turbines in the combined nozzle would be the most effective along the Adriatic Sea and on the coasts of the Mediterranean. They could ensure their owners considerably greater profits (as opposed to the current situation), jobs would open in industry and the installation business, and the local population would get good employments in building and maintaining these facilities.
