Description

VERTICAL AXIS WIND TURBINE

Branch of technology

Technical solution of wind turbine consist from upgrading it's eficiency, performance and automatic regulating wind turbine upgrades with vertical rotor based on mechanical, pneumatic and aerodynamic principles.

State of technolgy until today

Devices that use wind energy are thousands years known. First devices wich use wind energy . was sail ships and wind mills. It's constructions was made especially from wood, cloth, stone or bricks. This wind energy application was from 16. to 19. century upgraded and it was especially like sea ship propulsion, because large and flat area of sea level was curved only with sea waves and it has perfect conditions to use wind energy. Wind energy from it's discovery was used for many applications for example like sea sailing ships propulsion and some ships wich sail on < rivers and lakes, wheat milling, pumping of water and irrigation purposes. Advance of wind _ energy is zero polution, it mean that does not produce heat (with exception of compressors : powered by wind devices) carbon dioxide and other pollution and chemical compounds like reason of global warming and it's free. Most important wind energy misadvantage is it's instability, because it's performance depend on meteorologic conditions and devices, wich use it and very high wind speed in storm can case damage of any wind energy device. Along 18-th and 19-th century was upgrade iron and steel processing methods, and these technologies allow increase durability and resistance this kind of devices. Advance in branch of machinery, aerodynamics and meteorology allow upgrades of technical properties wind energy devices, but shipbuilding industry does not use wind energy today. Even similar wind turbine type was designed, original type of wind turbine has some very important missadvantages and diferences. First and most important different is that original wind turbine type does use Savoinus rotor, that case very strong whirling, low efficiency, low performance and strong binding of rotor at high rotation frequency. Second most important different against original wind turbine is missing performance regulation, and that is reason for entrance windhole wings lenght, performance and efficiency limitation with different wind speed and does not use admission effect on exit windhole. Original wind turbine type does not have lamellas on entrance windhole and rotor very high rotation protection.

wind energy devices dividing by construction:

a) with non moving parts - into this group belong especially wind sails used like historic and sport sails or land vehicles. Application for land vehicles like wheel vehicles or vehicles with slides necessary for transport on ice are used only for sport purposes.

b) with moving parts - into this group belong devices with horizontal and vertical rotors, like horizontal rotors with three flatboards as most spread wind energy devices in industries today for electricity production.

wind energy devices dividing by rotor type:

a) fast rotation and slow rotation horizontal flatboard rotors

b) horizontal rotors with gown turbine

c) Savoinus rotor it does mean flatboard rotor with vertical spin rotation based on different aerodynamical resistance by it's flatboars shape. This principle of different aerodynamical resistence is set by it's shape and wind direction, wich push on rotor flatboards.

d) Darieus rotor Essence of solution

This wind turbine is different from other types with vertical rotor, because it's turning cover increase vertical rotor performance. Savoinus rotor like vertical rotor type case very high whirling and that is reason for it's lower performance and has low durability against binding by excentricity force binding. This is reason why was not used in this wind turbine type with vertical rotor. Upgraded, enlighted, symetric costruction of vertical rotor is designed for maximal durability, rotation frequency tolerance and lowest possible weight. Diagonal area of four rotor flatboards with enter windhole lamellas make possible higher efficiency of wind energy application by horizontal streaming of air on rotor flatboards with it's rotation direction nearly in 90 degrees in relationship with sheet of flatboards. Turning cover is designed to catch maximal amount of air and allow it's very efficient directing on rotor flatboards thru enter windhole lamellas together with curve on right turning cover wing. Swinging assembled wings allow to regulate amount of streaming air and rotor turning frequency respectively wind turbine " performance in depence on wind speed. Advance in comparation with other wind turbine types is, that can use not only kinetic energy of wind, but it's dynamic pressure in enter windhole too. Admission effect based on special exit windhole shape create lower air pressure at wind speed higher than approximately 20 km/hour. Exit windhole shape is another purpose, how to increase performance and to correct turning cover direction against wind with enter windhole. Pneumatic regulating system of turning cover allow to join advances of slow rotation and fast rotation rotor and with partial closing of wings to decrease air stream in rotor at high wind speed. This system prevent tearing parts of rotor and prevent damage of other wind turbine parts. Partially closing of wings on enter windhole at high wind speed will decrease front wind pressure on whole device and it will prevent too high rotor rotation frequency, wind turbine owerthrown and breaking of carry axle-tree. Partially closing of enter windhole wings will derease air stream amount thru rotor to decrease rotor rotation frequency and to prevent tearing parts of rotor by excentricity force. Concave rotor axle-tree allow high resistance against jam, tolerance for carry axle-tree binding at strong and stroke wind, increase rotor durability and allow very simply mechanical connecting of devices wich use wind turbine performance.

Wind turbine construction consist of:

1 Carry axle-tree - this non moving parts is strongly fixed in soil. It's main carry part of whole wind turbine construction. It's part under surface is for fixation of whole device to sustain binding stress, as consequence of wind pressure on whole device and wind turbine parts. It's upper part above soil surface pass thru circle base, concave rotor axle-tree and turning cover. It's agile assembled by bearings with concave rotor axle-tree and turning cover of wind turbine. Carry axle-tree is divided on two parts, for more simply transport and installation, because it's whole lenght is bigger than lenght of trucks. Another reason for dividing of carry axle-tree on two parts is more simply manipulation with it's lower part, that is set and fixed under surface of soil.

2. ) Circle base - this part is fixed and set on soil surface and is non movably assembled by screws with carry axle-tree. It has circle shape and on it's upper side are agile cones assembled by bearings to allow easy turning of turning cover that depend on wind direction. It's agile assembled by bearings with concave rotor axle-tree and turning cover for agile turning around vertical axis of rotation. Circle base carry weight of rotor and all turning cover parts.

Rotor - purpose of this rotating part that is agile assembled by bearings for rotation on carry axle-base, circle base and in turning cover is to transform kinetic wind energy and wind pressure into applicable performance. It consist of four rotor flatboards and concave rotor axle-tree.

3. ) Rotor flatboards - change kinetic wind energy and wind pressure into applicable

performance. It's assembled with concave rotor axle-tree. Special connection with shaped steel insertions, fixing stick on concave rotor axle-tree and connecting ring allow high pull and push force durability, increase rotor flatboards triangle profiles durability against binding and allow simply mounting and exchange rotor flatboards. Rotor flatboards diagonal area in relation with axis of rotation, upgrade wind pressure angle on rotor flatboards sheets. Triangular shape of carry profiles on top and bottom edge rotor flatboards upgrade durability against binding stress, excentricity force and transmission acquired performance on concave rotor axle-base. Triangular profiles shape modify angle of rotor flatboards sheets for better wind pressure application on rotor flatboards and press air on outer vertical rotor flatboard edge together with excentricity force. Purpose of this modification is correct air direction which pass thru rotor into turning cover exit windhoie with minimal whirling.

4. ) Concave rotor axle-tree - transmit acquired performance from rotor flatboards on cogwheel

- respectively belt wheel fixed on concave rotor axle-tree bottom and allow very simply assembl of other device, increase rotor tolerance against jam and carry axle-tree tolerance for binding at shaking and at high rotation frequence. Cogwheel or belt wheel for assembling of belt or chain is fixed on concave axle-tree bottom, where transfer performance by chain respectively belt into other device wich use acquired performance. Suitable devices are compressor and pump for pumping of water or different liquid. Variable rotation frequency is reason of high energy losses for synchronization with electricity frequency and phases amplitude in electric distribution network and it is case that wind turbine is not suitable for direct elektricity production.

Turning cover - this moving construction part of wind turbine consist of this parts:

5. ) Cylinder cover with exit windhoie - on this part are assembled all other parts of turning cover wich turn around carry axle-tree against wind with enter windhoie. Enter windhoie has rectangle shape and is fixed by vertical stick profiles, wich prevent it's binding like consequence of wind pressure and serve as security cage for enter windhoie wings. On left and right vertical edge are assembled wing pegs of enter windhoie. On top and bottom enter windhoie edges are

horizontally mounted straight steel sheets with shaped start edge. It direct catched wind into rotor together with enter windhoie wings. It's start edge is shaped like stop motions for edge positions of enter windhoie wings. It cover top and bottom of enter windhoie, rotor and exit windhoie. This horizontal plates are carry construction parts for wing pegs, sprirall pegs, pneumatic control system, stop motions, lamellas turning axle-trees and concave rotor axle-tree. Space between enter windhoie wings and horizontal plates must be miriimal (not more than one milimeter) to prevent leak of catched wind. Bottom, circle horizontal area is enforced and shaped to carry weight of all other turning cover parts and to allow it's free rotation on rotating cones of circle base. Shape of exit windhoie is designed for minimal wind resistance and low pressure production. Purpose of vertical triangular curve with rounded edge is to prevent strong whirling and to divide air released thru exit windhoie and it's remnant is returned back into rotor space. Admission effect is created by extension of exit windhoie on it's left and right side end. It produce low pressure, that mean lower air pressure and wind stream expansion inside than outside. This principle is well known and used on aircrafts wings to produce aerodynamic lifting force. It increase this wind turbine performance, because rapidly increase wind stream size inside exit windhoie and decrease it's pressure inside in comparation with outside. Faster wind stream outside exit windhoie pull slower wind stream inside windhoie and that way is low pressure produced to increase wind turbine performance.

6. ) Wings of enter windhoie - purpose of this two swinging parts is to regulate amount of wind stream and it's directing into enter windhoie. It's vertically and agile assembled on vertical edges of turning cover enter windhoie and at high wind speed, wich can case wind turbine damage are partially closed in depency on stop motions set on top and bottom horizontal start edges. Space between enter windhoie wings, top and bottom straight horizontal plates inside is agile tighded by horizontal cylinders for free moving of enter windhoie wings at opening and closing. Curve on right wing direct wind behind lamellas of enter windhoie. It's purpose is to change air direction behind lamellas to perpendicular direction in comparation with rotor flatboards into rotor rotation direction, to upgrade efficiency and to modify vector of pressure on flatboards. 7. ) Directing lamellas - it's purpose is to direct wind, that pass thru enter windhole that way to push flatboards into it's rotation direction and this way to increase kinetic energy application efficiency of wind stream. In sight from front side cover approximately one half of enter windhole and prevent streaming of wind against rotor rotation direction. It's agile assembled with vertical axle-trees thru comb on string shock absorber. It's purpose of turning agile assembly is strong and stroke wind shock absorbtion and protection against too high rotation frequency and tearing part of rotor. At too high wind speed it turn at 100 degrees horizontal angle and direct wind stream to break rotor rotation. After decreasing rotor rotation frequency and speed of wind, wich pass thru rotor is it turned back by string in string shock absorber into it's original position.

8. ) String shock absorber and lamellas stop motions - String shop absorber is on top side of turning cover. Lamellas stop motions are set inside enter windhole edges, where begin work space of rotor. It's purpose is to chanche wind direction in depence on dynamic wind pressure on lamellas. Higher pressure at higher wind speed turn lamellas into correct position for

perpendicular wind pressure on flatboards. Another purpose is to absorb stroke wind and use it's energy to increase wind turbine performance. Wind pressure on lamellas is transmitted from lamellas turning tree-axes, thru comb into string piston. Lamellas turning axle-trees are set in one third of their width on inner side. Purpose of this design is turn lamellas in depence on wind, absorb stroke wind and correctly direct wind into rotor space. String shock absorber absorb pressure and stroke wind on lamellas. Stop motions (it mean edges on upper and lower horizontal area of enter windhole) prevent turning of lamelas into working space of rotor. String absorber and lamellas stop motions serve like wind turbine rotor protection against lamellas turning into work space of rotor because that can case lamellas fracture and damage of rotor. String shock absorber and lamellas stop motions serve like wind turbine protection of rotor, prevent dangerous rotor rotation frequency and serve like aerodynamical break. Exceeding of secure wind speed and pressure that stream thru lamellas defined by top rotation frequency of rotor and settings of string shock absorber case turning of lamellas into aerodynamic brake position. That mean to direct wind against rotation direction, to decrease rotor rotation frequency and to prevent tearing part or damage of rotor by excentricity force.

9. ) Spiralis - spiralis purpose is fluent and strong enough closing and opening wings of windhole. High wind speed create strong pressure on enter windhole wings. That is reason why is necessary to swing wings of enter windhole to position parallel with wing direction, to decrease wind stream amount and to decrease wind pressure on whole device. This wing position has several advances. Wind turbine can work properly at high wind speed, because it decrease size of wind stream thru rotor on one third. Front side wind pressure and turning cover air resistence is reduced to ininimal value to prevent overtrown of whole turning cover and to prevent binding or breaking of carry axle-tree and damage of rotor.

10. ) Spirall pegs - transfer pull and push force on spiralis to open and to close enter windhole wings. Outer spirall pegs are turning assembled thru slide bearings and vertical sticks into enter windhole wings on wings top and bottom. Inner spirall pegs are set on top and bottom vertical area of mrning cover. All inner spirall pegs has turning agile matrix for closing of wings at high wind speed and it's opening at low wind speed. Matrixes are assembled thru chain transmision into small rotor powered by compressed air, that turn matrixes in inner pegs. This construcing solution allow to transfer by screws pull respectively push force in both directions with fluent and strong enough force at high wind speed that case high pressure on wings of enter windhole.

11. ) Pneumatic control system - is main directing and control unit of whole wind turbine. It's purpose in depence on wind speed is to close or to open enter windhole wings. At critical wind speed this control system release compressed air from reservoir of compressed air thru pipes into inner screw pegs and that way to open or to close wings of enter windhole. It's part is compressor powered by belt. Belt transmit performance from rub coupling into compressor inside pneumatic control system box and absorb shocks together with rub coupling.

12. ) Reservoir of compressed air - hold compressed air for purpose of pneumatic control system. 13. ) Rub coupling - it's lower disk is stationary mounted on concave rotor axle-tree. Upper disk move up or down along grooves with compressed air piston and string in depence on air pressure in reservoir of compressed air. Upper disk is pushed with string that is pressed with compressed air piston. When air pressure in reservoir of compressed air decrease it case that compressed air piston release string, wich push two disks of rub coupling together and belt transmision initiate compressor of pneumatic control system.

14. ) Direction wing ~ purpose of this vertical part fixed on upper horizontal area of exit windhole is turning of turning cover into correct position with enter windhole against wind direction.

Examples of realization

Wind turbine use kinetic energy of wind like all other wind turbines and rotor types. It consist of several main construction parts. Purpose of carry axle-tree I fixed under soil surface is prevent overthrowing of whole device by wind pressure, it serve like fixing column and axle-tree for rotor and turning cover. Axle-trees are well known from cars and columns of sky-scrapers, for stabilization against overthrowing at strong wind. Circle base 2 is metal cast, that carry weight of rotor and turning cover to allow free turning around vertical rotation axis wich pass thru center of carry axle-tree \ . On circle base 2 bottom side are cavities and holes like space for belt respectively chain for performance transmission and for saving of metal. Many machines and buildings like statues use bases for fixing it's position and correct weight dividing on surface. Rotor consist of four rotor flatboards 3 and concave rotor axle-tree 4. Rotor flatboards 3 has triangular profiles designed for assembling of flat sheets that hold wind pressure that pass thru rotor space. Triangular rotor flatboards 3 are plugged and fixed into concave rotor axle-tree 4 to prevent it's tear up with binding and excentricity force. Flat sheet of material on rotor flatboards 3 is supported by diagonal supports assembled with concave rotor axle-tree 4 and rectangular shape profile on outer edge of flatboards 3. Special connection with steel ring, insertions and fixing sticks on concave rotor axle-tree 4 allow simply and durable connection of rotor flatboards 3 with concave rotor axle-tree 4. As I know, this kind of assembly is new even metal rings are used similar way in ball bearings. This kind of fixed assembly rotor flatboards 3 with concave rotor axle-tree is simillar with connection of flatboards on axle-tree of jet engines and other gas turbines types. Cylinder cover with exit windhole 5 is most important wind turbine part, because together with other parts assembled on it direct wind thru rotor, catch wind energy, direct wind into exit windhole and divide work space of rotor from outer environment. It purpose is same like at case of horizontal rotors with gown cover. On cylinder cover with exit windhole 5 are in enter windhole agile turnable assembled wings of enter windhole 6. It's purpose is to regulate wind amount that pass thru rotor to be opened at slow wind, it mean to catch maximal amount of air and to close when wind speed become critical. Main reason for this setting is to decrease front wind pressure on wind turbine at high wind speed to prevent it's overthrown or damage of rotor. Second reason is wind turbine properly function at high wind speed too in range of allowed rotor rotation frequency respectively performance decreasing defined by rotor construction durability and excentricity force. Wings of enter windhole 6 principle is well known from all doors with pegs, it mean that are assembled to swing at 45 degrees angle range.

Directing lamellas 7 are set in enter windhole between wings of enter windhole 6 and are assembled with sticks to swing on top and bottom of inner horizontal area in cylinder cover with enter windhole 5. Directing lamellas 7 purpose is to direct wind parallely with rotor rotation direction, absorb wind shocks, use it's energy and to swing in 100 degree angle like air brake, to protect against too high and dangerous rotor rotation frequency and that way prevent damage, curving respectively tearing it's part by excentricity force. Fixed lamellas are well known from ventilation systems. These systems are equipped with fixed lamellas on rotors, that propell air into ventilation systems. Directing lamellas 7 must not cross working space of rotor to prevent impact rotor into lamellas, that prevent string shock absorber and lamellas stop motions 8. String shock absorber and lamellas stop motions 8 consist of from verticall edges on inner horizontal top and bottom of enter windhole, top area placed stop motions of comb and string shock absorber piston. It absorb wind pressure that push on lamellas, absorb wind shocks on lamellas and protect rotor against too high and dangerous rotor rotation frequency if fail pneumatic control system I I . Lamellas swinging at 100 degrees angle direct wind against rotor rotation direction and that decrease it's rotation frequency below dangerous value and prevent damage of rotor by excentricity force. Spiralis 9 and spirall pegs 10 transmit compressed air force for closing and opening wings of enter windhole 6. High wind speed create big push force from inside on wings of enter windhole 6. Spiralis 9 and spirall pegs K) allow fluent pull with strong enough force without hits to close wings of enter windhole 6. Anoter reason is to decrease front push force on whole wind turbine to prevent it's overtrown and to prevent pass of secure rotor rotation frequency. Spiralis are well known for transport of loose materials, even in this case is better comparation with screw and matrix. Screws and matrixes like assemble parts are well known and used very often. Screws and matrixes same as spiralis 9 and spiralis pegs 10 can create big pull force and fluid movement. It was necessary use chain gear with spirall pegs 10, because wings of enter windhole 6 pressure force create big resistance against turning of matrixes in spirall pegs 10. Air pressure from pneumatic control system ϋ and reservoir of compressed air 12 can't turn matrixes in spirall pegs 10 strong enough without chain gear.

Pneumatic control system Π. based on anemometer and tachometer regulate rotor rotation frequency thru spirall pegs 10 and compress air with compressor into reservoir of compressed air 12. Anemometer is connected with tachometer and set for opening of valve at critical wind speed to release air from reservoir of compressed air 12 thru pipes into inner spirall pegs 10 and thru spiralis 9 close wings of enter windhole 6 to decrease amount of streaming wind and rotor rotation frequency. Compressor like part of pneumatic control system H is powered by rub coupling 13. Is difficult to compare simillarity of pneumatic control system 11 with other control systems, all it's parts: anemometer, tachometer, compressor and valves are well known and usually used devices in metorologic stations and many branch of industries. Reservoir of compressed air 12 is connected by pipe with compressor in pneumatic control system H and second pressure pipe is connected with pneumatic piston in rub couple 13. In rub couple 13 is string holded by pneumatic piston and that way divide disks of rub coupling 13 from themselves. When pneumatic control system H. is initiated, valve release compressed air into pipes and it decrease pressure in reservoir of compressed air 12 and that release string in rub cuple 13 pressed by pneumatic piston. It push rub couple 1J. disks together and begin transfer

performance from rotor to compressor of pneumatic control system Π.. This solution has three advances. Rub couple 13 at high rotor rotation frequency begin to work as rotor break, absorb shocks at start of compressor and begin to power compressor for compressed air production, as necesary condition for properly function of pneumatic control system Π_. Rub couples are most often used in motorcycles and personal cars, transfer performance from combustion engine into gear box, equalize different rotation and absorb engine and gear box axle-trees shocks and stress at gears switching. Direction wing 14 is placed on top, backward area of exit windhole. It's purpose is hold cylinder cover with exit windhole 5 in correct direction with enter windhole against wind. Direction wing 14 has same purpose like direction wings on airplanes, it mean that hold cylinder cover with exit windhole 5 turned with enter windhole against wind. Direction wing 14 is based on simple principle of it's shape and air resistance. Wind direction change case side pressure on direction wing 14 and exit windhole. This pressure force turn cylinder cover with exit windhole 5 into correct direction aginst wind with enter windhole, what is necessary condition for properly function of rotor and whole wind turbine.

Industry applications

Wind turbine is suitable for wind energy application in agriculture, energy industry and sea ship transportation. In industry is suitable for energy acumulation into reservoirs of compressed air and saving of electricity necessary as compressors power source. Is suitable like compressed air power source of stationary piston engine, under condition that piston engines are modified for this purpose. Wind turbine can increase performance of hydroelectric power stations, like water pumps power source for pumping of water below dam back to fill dam with water again and acumulate energy into height position energy of water inside dam. Very perspective application of this wind turbine can be fuel consumption decreasing in sea ship diesel engines like additive wind energy power source. Performance transfer can be made by cyclic pumping of hydraulic liquid into hydrodynamic coupling, or turbine designed for liquid. Performance can be transmitted by direct mounting of hydrodynamic coupling respectively liquid turbine on ship propellers axle-trees and can be distributed by pipes and regulated with valves. Direct electricity production can be very complicated, because is necessary to add electric generator and electronic device for synchronization of electricity phases and frequency with distribution electricity network what can case higher expences and energy losses. Most suitable way for electricity production is for lights respectively other electric devices, temporary disconnected from electric distribution network and with tolerance of unstable electric phases and frequencies like bulbs. For electric engines, computers and other electric devices that need correct electric frequency and phases synchronization is this source of electricity non suitable and very problematic.

Suitable can be direct mechanic power source by stationary modified piston engines, or small compressed air rotors for example like power source for water pumps and milking devices vacumers in farms. Wind speed variability is reason that this wind turbine type is more suitable for devices with interrupted working, because it allow acumulate compressed air into reservoirs of compressed air. Energy acumulation into electric batteries is not correct application, because is complicated and expensive. Energy acumulation with compressed air is very ecologic too, because does not need toxic and acid chemicals like electrochemical bateries. Another suitable compressed air application is loose material transportation, like grain or cement. Compressed air can be used for cleaning grain from chaffs, climatization and additive power source for grain mills in depency on compressed air device type, wich can use compressed air. Transport companies can use this wind turbine like gear compressor respectively filling of compressed air based brake systems without fuel consumtion to decrease expences for naphtha.
