<1 Innledning><1 Introduction>

Dagens teknologi Today's technology

Store vindmøller med horisontal rotasjonsakse ser ut til å være vinnere ved dagens utbygginger av vindmøller. Large wind turbines with a horizontal axis of rotation seem to be winners in today's development of wind turbines.

Av større vindmøller med vertikal rotasjonsakse, henvises det til de historiske vindmøllene i Nashtifan, Iran. Disse sies å fortsatt være i bruk. Of larger windmills with a vertical axis of rotation, reference is made to the historic windmills in Nashtifan, Iran. These are said to still be in use.

Felles for de nevnte vindmøller er at de er avhengige av vindretningen. What the aforementioned windmills have in common is that they are dependent on the direction of the wind.

Den gjeldende oppfinnelsen adresserer vindretningsuavhengig energifanger (1) , samt fremming av oppstarten av vindmøllen ( tegning/fig.5 ), og vindmølle ( tegninger/ fig.4 og fig.8 ). The current invention addresses wind direction-independent energy capture (1), as well as promoting the start-up of the windmill (drawing/fig.5), and windmill (drawings/fig.4 and fig.8).

Behov for ny teknologi Need for new technology

En mengde ulike konsepter finnes både for horisontale og vertikale vindmøller. Fortsatt er det ønskelig med nye løsninger dersom disse er mer effektive og billigere, både å bygge og å drive og å gjenvinne materialene i de. A number of different concepts exist for both horizontal and vertical wind turbines. It is still desirable to have new solutions if these are more efficient and cheaper, both to build and to operate and to recover the materials in them.

Funksjon og beskrivelse av energifanger Function and description of energy trap

Uavhengigheten av vindretningen oppnås ved at det benyttes en gruppe av energi-fang-elementer (2) som har en konkav og en konveks side( tegning/ fig.5 ). Ellementene består av svakt bøyde rektangulære plateelementer festet til hvert sitt bjelkeelement (4). Bjelkeelementene er hengslet (7) til horisontale åk, som igjen står horisontalt ut fra en vertikal stamme, som igjen roterer når tilstrekkelig med vind tar tak i fang-elementene. De bøyde fang-elementene får en konveks side og en konkav side ( tegning /fig.5 ). For vind fra samme retning oppstår det ulike krefter på diametralt motsatt plasserte fang-elementer. I tillegg oppstår det ytterligere ulike krefter fordi de hengslete elementene i utgangspunktet henger på skrå p.g.a. tyngdekraften til fang-lementene ( tegning/fig.5 ) . Når viden tar tak i den konkave siden av et element, vil det svinge med vinden til det står vertikalt og gir størst motstand mot vinden. Tilsvarende vil et konvekst elment svinge med vinden til det blir liggende horisontalt og gir sin minste motstand mot vinden. Ligger et konkavt fang-element diametralt motsatt til et konvekst fang- element, vil det konkave fang-elementet gi et større dreiemoment enn det motsatt virkende konvekse fang-elementet. Når vinden kommer parallelt med de to fang-elementene, vil det også oppstå større krefter på den konkave siden av fang-elementene, enn på den konveksee siden, og derved oppstår et dreiemomentbidrag i samme retning som for vindretning normalt på fang-elementene. The independence of the wind direction is achieved by using a group of energy capture elements (2) which have a concave and a convex side (drawing/fig.5). The elements consist of slightly bent rectangular plate elements attached to each individual beam element (4). The beam elements are hinged (7) to horizontal yokes, which again stand horizontally from a vertical stem, which again rotates when sufficient wind takes hold of the catch elements. The bent catch elements have a convex side and a concave side ( drawing /fig.5 ). For wind from the same direction, different forces arise on diametrically oppositely placed catch elements. In addition, further different forces arise because the hinged elements initially hang at an angle due to the gravity of the catch elements ( drawing/fig.5 ). When the vine takes hold of the concave side of an element, it will swing with the wind until it is vertical and offers the greatest resistance to the wind. Similarly, a convex element will swing with the wind until it lies horizontally and offers its least resistance to the wind. If a concave catch element is located diametrically opposite to a convex catch element, the concave catch element will produce a greater torque than the oppositely acting convex catch element. When the wind comes parallel to the two fang elements, greater forces will also arise on the concave side of the fang elements, than on the convex side, and thereby a torque contribution occurs in the same direction as for wind direction normal to the fang elements.

Claims

Alternative energy capture elements

The energy capture elements can alternatively have the greatest length in the vertical direction, and consist of multiple sub-elements. The sub-elements can primarily consist of half pipes, where the wall thickness can vary from completely thin walls to closer to half a cylinder. Between each of the elements there is a gap (15). The catch elements are attached to one or more yokes (5). A shaft (3) is attached to the center of the yoke(s) (5).

Function and description of windmill

A windmill with a vertical, or predominantly vertical axis of rotation, (drawings /fig.1 and fig.3), consists of multiple energy collectors (1) in one or multiple levels, and a shaft (3), as well as one or more hubs / bearings ( 14), and a coupling (11), and a gear (8), and a generator (9), as well as a support structure (12).

3 Drawings

On the drawings/figures 1, 4, 6, 8 and 9, energy traps are shown with elevation and ground plan. Drawings/fig.4 and fig.8 show how an entire wide mill is put together.

4 Patent requirements

1. Multiple bent and hinged catch elements, with one or multiple hinges attached to multiple yokes, which in turn are attached to a rotating stem/shaft that is vertical or with a few degrees of deviation from vertical.

2. A group of vertical energy capture elements consisting of a sum of sub-elements having a concave and a convex side, with a gap (15) between each of the sub-elements (22), and the elements (22) are primarily half pipes, where the wall thickness can vary from thin and up to half a cylinder and where the catch elements are attached to a curved beam which in turn is attached to a straight beam, which in turn is hinged to a yoke, which is in turn attached to a rotating stem/axle which is vertical or with a few degrees of deviation from the vertical.

5 Summary

A wind direction-independent energy collector, used in a windmill with a vertical, or nearly vertical axis of rotation. The windmill can be varied from a small one to a very large mill, which is independent of wind direction. The wind catcher "surfaces" can be made very large. The windmill does not need to be steered against the wind, and therefore has no machinery for that kind of steering. This constitutes a cost-saving element compared to today's large horizontal wind turbines.

The new thing added through this solution is that large "wind catchers - surfaces" can be used in a vertical windmill, and that the start-up property is promoted.
