Description

7804020-1 - I fig 1 illustreras en vertikal axel 1 med en rotor bildande vind- blad 4 och en horisontell axel 2 med vindblad 4lsamt en synkroni- sering 3. Vidare visas en anordning med stagning och eqvindrikt- ningsföljande skärm 5. Även ett styrblad 8 och en generator 6 samt dessas placering framgår. 7804020-1 - Fig. 1 illustrates a vertical shaft 1 with a rotor forming wind blade 4 and a horizontal shaft 2 with wind blade 4 as well as a synchronization 3. Furthermore, a device with bracing and wind direction following screen 5 is shown. Also a guide blade 8 and a generator 6 and their location are shown.

I fig 2 visas generatorn 6 uppifrån med vertikalaxelns 1 (mastens) funktion att driva generatorn 6 samt vindriktnings-skärmen 5 med rullager 5'. Dessa rullager 5' för eller styr skärmen 5 och axeln 2 till horisontalrotorn 4'runt ett fundament 12 varvid skärmen eallfia föl jer vinariktningen.Fig. 2 shows the generator 6 from above with the function of the vertical axis 1 (mast) to drive the generator 6 and the wind direction screen 5 with roller bearings 5 '. These roller bearings 5 'guide or guide the screen 5 and the shaft 2 to the horizontal rotor 4' around a foundation 12, the screen or the following following the direction of the wine.

Fig 5 anger hurusom horisontalvindbladen 4' regleras med en stång 7 som förflyttar ettkullager 10 fram och åter utmed axeln 2 med hjälp av ett styrblad 8. Det framgår att med en anordning 11 vrides horison- tfiñmMmm4'ifimähmefinswflhæwßimfiflmwav vindtrycket. Fjädern 9 är ett ställbart mottryck mot vindtrycket.Fig. 5 shows how the horizontal wind blades 4 'are regulated with a rod 7 which moves a ball bearing 10 back and forth along the shaft 2 by means of a guide blade 8. It can be seen that with a device 11 the horizontal fi ñmMmm4'i fi mähme fi nsw fl hæwßim fifl mwav wind pressure is rotated. The spring 9 is an adjustable back pressure against the wind pressure.

Fig 4 illustrerar den vindriktningsföljande skärmens 5 konstruktion och arbetssätt, med utjämning av rotationshastigheten genom den av vindtrycket på styrbladet 8 uppkomna sidovridningen av skärmen 5.Fig. 4 illustrates the construction and working method of the wind direction-following screen 5, with equalization of the rotational speed by the lateral rotation of the screen 5 caused by the wind pressure on the guide blade 8.

Detta åstadkommas av horisontalvindbladens 4' medverkan med den successiva vridningen av vindbladen ända fram till parallellt med vindriktningen. Därav uppstår denna sidovridning samtidigt av skärmen 5 och axeln 2 och av att horisontalvindbladen 4' även verkar i sidled. Detta gör att hastigheten bromsas upp, och vid onormalt hård vindstyrka står vindkraftverket stilla. Detta uppstår av att skärmen 5 helt täcker mastens vertikala vindblad, och axelns 2 ' horisontalvindblad blir samtidigt helt parallella med vindriktning- en. Därav omöjliggöres all rotation av vindkraftverket.This is achieved by the participation of the horizontal wind blades 4 'with the successive rotation of the wind blades all the way to parallel to the wind direction. As a result, this lateral rotation arises simultaneously of the screen 5 and the shaft 2 and of the fact that the horizontal wind blades 4 'also act laterally. This slows down the speed, and at abnormally strong winds, the wind turbine stands still. This arises from the fact that the screen 5 completely covers the vertical wind blades of the mast, and the horizontal wind blades of the shaft 2 'become at the same time completely parallel to the wind direction. This makes all rotation of the wind turbine impossible.

Det som här framkommit är endast ett exempel. Vid normal vindstyrka - som är mest förekommande - verkar vindkraftverket så, att högsta möjliga effekt går att utvinna.What has emerged here is only an example. At normal wind speeds - which are most common - the wind turbine works in such a way that the highest possible effect can be extracted.

Tekniska exempel som ytterligare belyser vindkraftverkets funktion.Technical examples that further illustrate the wind turbine's function.

När fjädern 9 med styrbladet 8 inställes för ett víndtryck som mot- svarar t.ex. 8 sekundmeter, med därav uppkomna varvantal på vind- kraftverket, och när vinden.därefter ökar till exempelvis 12 sekund- meter, vridas horisontalbladen 4'para11el1t med vindriktningen några 7804020-1 grader, och samtidigt vridas därav skärmen 5, och minskar vind- fånget på vertikalbleden 4. På så sätt bibehålles hastigheten som motsvarar 8 sekundmeter trots att vindhastigheten fortfarande är 12 sekundmeter. Alltså: När vinden varierar reglerar styrbladet 8 till jämnare gång på vindkraftverket.When the spring 9 with the guide blade 8 is set for a wind pressure corresponding to e.g. 8 second meters, with resulting speeds at the wind turbine, and when the wind then increases to, for example, 12 second meters, the horizontal blades 4'para11el1t with the wind direction are turned a few 7804020-1 degrees, and at the same time the screen 5 is turned, and the wind catch is reduced on the vertical blade 4. In this way, the speed corresponding to 8 seconds is maintained, even though the wind speed is still 12 seconds. Thus: When the wind varies, the guide blade 8 regulates to a smoother course on the wind turbine.

Hastighetsnivån är beroende av fjädern: 9 inställning. Alltså: Hård inställning på fjädern betyder hög/varierande/hastighetsnivå, och lös inställning på fjädern betyder låg/varierande/hastighetsnivå.The speed level depends on the spring: 9 setting. Thus: Hard setting on the spring means high / varying / speed level, and loose setting on the spring means low / varying / speed level.

Allt fungerar synkront, som en enda stor maskin, med en effekt som överstiger verk som har enbart horisontal-vindblad, eller enbart vertikal-vindblad.Everything works synchronously, like a single large machine, with an output that exceeds plants that have only horizontal wind blades, or only vertical wind blades.

Karakteristiskt för det uppfinningsenliga vindkraftverket är vidare att det har vertikala 1 och horisontella 2, samverkande, synkroni- serade axlar, som medbâmonterade vindblad 4 och 4' av vinden driver både horisontellt och vertikalt axelmasten 1 i rotation. Av den härav uppkomna stora effekten drives den på mastens nedre del an- slutna generatorn 6, Detta sker med styrbladets 8 medverkan som även höjer vindeffekten, Detta resultat kan endast erhållas av den dubbelverkande vertikal- horisontella effekten, och av en vindledande anordning 8 som även ökar vindhastigheten genom sin snedställning mot vinden, och för vinden mer i vinkel mot vindbladens 4 yta, som ytterligare ökar effekten. Även jämnare gång med enbart hög eller enbart låg hastighet på vindkraftverket erhålles av vindstyrbladets 8 vridning fram och åter med fjäderns 9 inställning mot vindtrycket. Vindstyrbladet är med en stång 7 förbunden till horisontalvindbladen 4, som därav vrides i olika grader (även parallellt med vinden) av anordningen 11, i överensstämmelse med vindtrycket på vindstyrbladet 8 som är vridbart.Characteristic of the wind turbine according to the invention is further that it has vertical 1 and horizontal 2, cooperating, synchronized axes, which co-mounted wind blades 4 and 4 'of the wind drive both horizontal and vertical shaft mast 1 in rotation. Due to the large power resulting from this, the generator 6 connected to the lower part of the mast is driven. This is done with the participation of the guide blade 8, which also increases the wind power. This result can only be obtained by the double-acting vertical-horizontal power, and by a wind-conducting device 8. increases the wind speed through its inclination towards the wind, and for the wind more at an angle to the surface of the wind blades 4, which further increases the effect. Even smoother running with only high or only low speed on the wind turbine is obtained by the rotation of the wind guide blade 8 back and forth with the spring 9 setting against the wind pressure. The wind guide blade is connected by a rod 7 to the horizontal wind blades 4, which are thereby rotated to different degrees (also parallel to the wind) by the device 11, in accordance with the wind pressure on the wind guide blade 8 which is rotatable.

Av detta framgår att synkroniseringen av axlarna 1 och 2 är en för- utsättning för att även få samverkan/synkronering mellan styrblad 8 och horisontal- och vertikal-vindbladen 4', 4. Dessa moment sammanhålles av stöd och den vindföljande skärmen 5. _r78Û4Û2Û-1 När fjädern 9 är fast inställd och därmed även styrbladet 8, upp- tages all vindkraft och den högsta rotationshastigheten uppstår.From this it appears that the synchronization of the shafts 1 and 2 is a prerequisite for also having cooperation / synchronization between guide blades 8 and horizontal and vertical wind blades 4 ', 4. These elements are held together by support and the wind-following screen 5. _r78Û4Û2Û- 1 When the spring 9 is fixed, and thus also the guide blade 8, all wind power is absorbed and the highest rotational speed occurs.

Vid onormalt hård vindstyrka och därav för högt varvantal, utlöses fjäderns 9 säkerhetsanordning och förhindrar pâ så sätt skador på vindkraftverket. Alltså: Vid för hårt tryck på styrbladet 8 fri- kopplas fjädern 9 ur en spärranordning, och styrbladet 8 tryckes mot skärmen 5.In the event of abnormally strong wind strength and hence too high a speed, the safety device of the spring 9 is triggered and thus prevents damage to the wind turbine. Thus: If the guide blade 8 is pressed too hard, the spring 9 is released from a locking device, and the guide blade 8 is pressed against the screen 5.

När fjädern 9 är löst inställd och styrbladet 8 trycker mot skärmen vrides horisontalaxeln 2och skärmen 5 så att vertikalvindbladen 4 kommer i lä (skyddade) för vinden, och när då horisontalvind- bladen 4'samtidigt ställer sig parallellt med vinden, blir följden den att vindkraftverket successivt stannar upp hastigheten till i det närmaste stillastående. Detta är väsentligt vid hård orkanvind, och är ett av uppfinningens viktigaste särdrag.When the spring 9 is loosely adjusted and the guide blade 8 presses against the screen, the horizontal axis 2 and the screen 5 are rotated so that the vertical wind blades 4 are sheltered (protected) from the wind, and when the horizontal wind blades 4 are simultaneously parallel to the wind, the wind turbine gradually stops the speed to almost standstill. This is essential in strong hurricane winds, and is one of the most important features of the invention.

Horisontalvindbladen 4' kan begränsas till två eller utökas till ett flertal vindblad. Vertikalvindbladen 4 kan begränsas till ett eller utökas till flertal vindblad, och hela masten mer likna och verka som en turbin.The horizontal wind blades 4 'can be limited to two or extended to a plurality of wind blades. The vertical wind blades 4 can be limited to one or extended to several wind blades, and the whole mast more similar and act as a turbine.

Skärmen 5 stagar'utpvindkraftverkets konstruktion genom att alltid inställa sig på längden i riktning med vinden. Om så erfordras kan dessutom staglinor eller stüiinmonteras på vindkraftverket. Genera- torn 6 är direkt ansluten till vertikalaxelns 1 (mastens) nedre del.The screen 5 braces the construction of the wind turbine power plant by always adjusting the length in the direction of the wind. If required, stag lines can also be installed on the wind turbine. The generator 6 is directly connected to the lower part of the vertical shaft 1 (mast).

Det må slutligen påpekas att fjädern 9 kan ersättas med annan anord- ning, t ex ett hydrauliskt kolvsystem som kan regleras från manöver- bord.Finally, it must be pointed out that the spring 9 can be replaced by another device, for example a hydraulic piston system that can be adjusted from the control table.
