Patentkrav
1. Vertikalakslet vindturbin (1), hvori
hvert av flere rette rotorblader (12) er dreibart støttet omkring en vertikal rotorbladaksel (121) ved en turbinrotorbase (111) og ved et øvre endeparti (112) av en senteraksel (113) til turbinrotoren (11), senterakselen (113) er støttet av et aksiallager (131) til et stasjonært fundament (13),
senterakselen (113) strekker seg gjennom og er festet til et senterparti av turbinrotorbasen (111),
k a r a k t e r i s e r t v e d at
det stasjonære fundamentet (13) strekker seg fra en grunn (3) og er forsynt med et støttelager (132) anordnet for å støtte turbinrotorbasen (111) distalt fra senterakselen (113).
2. Vertikalakslet vindturbin (1) ifølge krav 1, hvori minst én kraftgenerator (14) er tilveiebrakt inni fundamentet (13).
3. Vertikalakslet vindturbin (1) ifølge krav 2, hvori en drivaksel (141) til den minst ene kraftgeneratoren (14) og en ringformet tannstang (115) festet til turbinrotorbasen (111) er sammenkoplet med utvekslingsmidler (142) anordnet for å omforme rotasjon av turbinrotoren (11) til rotasjon av drivakselen (141).
4. Vertikalakslet vindturbin (1) ifølge hvilket som helst av de foregående kravene, hvori en aktuator (15) er koplet til hver rotorbladaksel (121) og er anordnet for å styre vinkelposisjonen til rotorbladet (12).
5. Vertikalakslet vindturbin (1) ifølge krav 4, hvori aktuatoren (15) er tilveiebrakt nedenfor basen (111) til turbinrotoren (11).
6. Vertikalakslet vindturbin (1) ifølge hvilket som helst av de foregående kravene, hvori hvert rotorblad (12) er forsynt med flere bladseksjoner (12a, 12b, 12c) dreibart støttet av mellomliggende bladfester (114) som strekker seg fra turbinrotorens (11) senteraksel (113).
7. Vertikalakslet vindturbin (1) ifølge krav 6, hvori hver rotorbladseksjon (12a, 12b, 12c) er koplet til én av flere in-line rotorbladseksjonsaksler (121a, 121b, 121c), hver av rotorbladseksjonsakslene (121a, 121b, 121c) kopler sammen hver rotorbladseksjon (12a, 12b, 12c) og en rotorbladseksjonsaktuator (15a, 15b, 15c) anordnet for å uavhengig dreie hver rotorbladseksjon (12a, 12b, 12c).
8. Vertikalakslet vindturbin (1) ifølge hvilket som helst av de foregående kravene, hvori et kontrollsystem (2) er anordnet til å kontinuerlig overvåke vindretning og vindhastighet ved å samle og prosessere signaler fra ett eller flere anemometre (21) tilveiebrakt ved turbinrotoren (11).
9. Vertikalakslet vindturbin (1) ifølge krav 8, hvori trådløs signaloverføring fra det ene eller flere anemometrene (21) til kontrollsystemet (2) er tilveiebrakt.
