. Vindmølle. Windmill
Oppfinnelsen vedrører en vindmølle av det slag som er angitt i innledningen til patentkrav 1, for omforming av vindenergi til annen utnyttbar energi, særlig elektrisk energi. The invention relates to a windmill of the type specified in the introduction to patent claim 1, for converting wind energy into other usable energy, in particular electrical energy.
Hovedformålet med oppfinnelsen er å skape en vindmølle som har høyere virkningsgrad og større ytelse ved varierende vind enn tilsvarende kjente vindmøller. The main purpose of the invention is to create a windmill that has a higher degree of efficiency and greater performance in varying winds than similar known windmills.
Ifølge oppfinnelsen kan dette oppnås ved hjelp av en vind-mølle som er utformet i samsvar med patentkrav 1. According to the invention, this can be achieved with the help of a windmill which is designed in accordance with patent claim 1.
Ytterligere fordelaktige trekk ved oppfinnelsen vil gå fram av underkravene. Further advantageous features of the invention will be apparent from the subclaims.
Oppfinnelsen vil nedenfor bli beskrevet nærmere under hen-visning til et utførels^eseksempel vist i tegningene, hvor fig.l viser et delvis oppskåret planriss ovenfra og fig. 2 et delvis oppskåret sideriss- av en vindmølle utf ormet vi samsvar med opp^finnelsen. The invention will be described in more detail below with reference to an embodiment shown in the drawings, where fig. 1 shows a partially cut plan view from above and fig. 2 is a partially sectioned side view of a windmill we designed in accordance with the invention.
Den viste vindm.01.le omfatter to hoveddeler, nemlig en luft-fanger og en rotor. The shown windm.01.le comprises two main parts, namely an air trap and a rotor.
Luftfangeren består av søyler eller blad 3 med kjent aerodynamisk profil, som er oppstilt i en sirkelformet rekke som opp-gir rotoren, Disse bladene eller vingene er plassert eikeformet med en bestemt vinkel eller skrås till ing, slik at det dannes kanaler mellom dem, gjennom hvilke vinden blir fanget og ført fram:- til bladene til rotoren som vil bli beskrevet nedenfor. The air catcher consists of columns or blades 3 with a known aerodynamic profile, which are arranged in a circular row that gives rise to the rotor. These blades or wings are placed oak-shaped with a certain angle or oblique tilling, so that channels are formed between them, through which the wind is caught and brought forward:- to the blades of the rotor which will be described below.
En slik utformet vindfanger med en sirkelformet rekke verti-kale vinger vil fange opp vinden over omtrent 180° av en sirkel og over hele sin høyde. En slik vindfanger virker slik i alle kvadranter at den ikke trenger ytterligere mekanisk ledeutstyr. A wind catcher designed in this way with a circular array of vertical wings will catch the wind over approximately 180° of a circle and over its entire height. Such a wind catcher works in all quadrants so that it does not need additional mechanical guidance equipment.
Vingene 3 er festet til en King ved overkanten og til en plate eller skive ved underkanten. Vindmøllens rotor 2 kan føres inn i vindfangeren gjennom åpningen i overkanten, idet denne åpning dekkes av en plate 4 som festes til ringen som holder The wings 3 are attached to a King at the upper edge and to a plate or disc at the lower edge. The windmill's rotor 2 can be introduced into the wind catcher through the opening in the upper edge, as this opening is covered by a plate 4 which is attached to the ring that holds
vingene 3 sammen ved overkanten.the wings 3 together at the upper edge.
Platen 4 ved overkanten tjener samtidig som deksel og som bærer for et lager 8 som holder rotoren, noe som vil bli beskrevet nærmere nedenfor. The plate 4 at the upper edge simultaneously serves as a cover and as a carrier for a bearing 8 that holds the rotor, which will be described in more detail below.
Platen som bærer vingene 3 ved underkanten er også betegnet med henvisningstall 4 og den tjener samtidig som bærer for et lager 9 ved rotorens underkant. The plate which carries the wings 3 at the lower edge is also denoted by the reference number 4 and it also serves as a carrier for a bearing 9 at the lower edge of the rotor.
Vindfangeren kan frams tilles • av armert betong dersom dimen-sjonene gjør dette nødvendig, eller av stål, aluminium, eller andre materialer som tilfredsstiller de aktuelle økonomiske og tekniske krav. The wind deflector can also be made • of reinforced concrete if the dimensions make this necessary, or of steel, aluminium, or other materials that meet the current economic and technical requirements.
Rotoren omfatter en sirkelformet rekke blad 5 med passende aerodynamisk profil og dimensjon, som er festet mellom to plater 6 som igjen er festet til en vertikal aksel 7 som bæres av lag-rene 8 og 9. The rotor comprises a circular array of blades 5 with a suitable aerodynamic profile and dimension, which are fixed between two plates 6 which are in turn fixed to a vertical shaft 7 which is supported by bearings 8 and 9.
Den viste utforming gjør vindmøllen ifølge oppfinnelsen dobbeltvirkende, noe som øker virkningsgraden betydelig. Kanal-ene som dannes av luftfangeren og som grovt kan sies å danne Venturi-rør, øker hastigheten på den innkommende vindstrømmen The design shown makes the windmill according to the invention double-acting, which increases the degree of efficiency significantly. The channels formed by the air trap, which can roughly be said to form Venturi tubes, increase the speed of the incoming wind flow
og øker dermed effekten på vindmøllen.and thus increases the effect on the windmill.
Rotoren kan på tilsvarende måte som vindfangeren framstilles av vilkårlige materialer, så som stål,, aluminium eller andre hensiktsmessige materialer eller kombinasjoner av materialer. The rotor can, in a similar way to the wind catcher, be produced from arbitrary materials, such as steel, aluminum or other suitable materials or combinations of materials.
Vindmøllen i utførelseseksempelet er videre forsynt medThe windmill in the design example is also equipped with
en teleskopisk sammenpassende rekke sylinderformete bremseele-menter 10 som er anbragt koaksialt med rotoren og med vindfangeren og som kan beveges opp og ned ved hjelp av hydrauliske syl-indre 11, idet det i eksempelet finnes fire slike sylindersett 11 jevnt fordelt langs omkretsen. Bremseelementene 10, som hen-siktsmessig er framstilt av stålplate, gjør det mulig å stoppe rotoren for vedlikehold og andre arbeider uten bruk av drivverks-bremser. a telescopic matching row of cylindrical brake elements 10 which are arranged coaxially with the rotor and with the wind catcher and which can be moved up and down with the help of hydraulic cylinders 11, in the example there are four such sets of cylinders 11 evenly distributed along the circumference. The brake elements 10, which are expediently made of sheet steel, make it possible to stop the rotor for maintenance and other work without the use of drivetrain brakes.
Drivkraften overføres fra akselen 7 ved hjelp av en hensikts-messig drivforbindel&e, som kan omfatte en girkasse eller liknende, til en generator 12, i eksempelet for generering av elektrisk energi. Vindmøllen ifølge oppfinnelsen kan imidlertid prinsippielt omforming av vindenergien til andre energiformer, for eksempel for pumping av væsker. The drive force is transferred from the axle 7 by means of a suitable drive connection, which may comprise a gearbox or the like, to a generator 12, in the example for generating electrical energy. However, the wind turbine according to the invention can in principle transform the wind energy into other forms of energy, for example for pumping liquids.
På grunn av den gode utnyttelse av energien i vinden, kanDue to the good utilization of the energy in the wind, can
en vindmølle ifølge oppfinnelsen utnyttes både ved små og store anlegg. a windmill according to the invention is used in both small and large installations.
