Description

40 7803411454 2 vingblad 3, vilka i det visade utföringsexemplet sträcker sig från konens 2 spets till dess baspartí. Man kan även tänka sig att exem- pelvis vartannat vingblad 3 endast sträcker sig utefter halva konens 2 höjd. Wing blades 3, which in the embodiment shown extend from the tip of the cone 2 to its base portion. It is also conceivable that, for example, every other wing blade 3 extends only along half the height of the cone 2.

Såsom framgår av fig. 1 är luftturbinen 1 roterbart lagrad på en axel 4 på ett hållarorgan 5, vilket i sin tur, via ett lager 6, är roterbart anbringat i en stolpe 7 för svängning i ett horisontal- plan.As can be seen from Fig. 1, the air turbine 1 is rotatably mounted on a shaft 4 on a holding member 5, which in turn, via a bearing 6, is rotatably mounted in a post 7 for pivoting in a horizontal plane.

Såsom tydligast framgår av fig. 1 och 3 ökar vingbladens 3 höjd mot konens 2 basparti. _ I det visade utföringsexemplet, se fig. 1, träffar en horison- tell linje 8 genom yttersta spetsen av ett vingblad 3 konen 2 i dess anslutningspunkt till nästföljande vingblad 3 i riktning mot konens Z basparti. Vid betraktande av turbinen l i axelns 4 längdriktning så täcker vingbladen 3 konens 2 mantelyta, se fig. 3. Därigenom upp- fångas vinden, vilken antytts med pilar i fig. 1 på ett optimalt Sätt, ÖVS- frisk energi utnyttjas ständigt på varje del av vingbladens yta.As can be seen most clearly from Figs. 1 and 3, the height of the wing blades 3 increases towards the base portion of the cone 2. In the exemplary embodiment shown, see Fig. 1, a horizontal line 8 through the outermost tip of a wing blade 3 strikes the cone 2 at its connection point to the next wing blade 3 in the direction of the base portion of the cone Z. When looking at the turbine in the longitudinal direction of the shaft 4, the wing blades 3 cover the mantle surface of the cone 2, see Fig. 3. Thereby the wind is captured, which is indicated by arrows in Fig. 1 in an optimal way. wing surface.

Vingbladens 3 vinkel mot konens 2 mantelyta kan naturligtvis varieras för att erhålla den för varje användningsområde bästa effek- ten.The angle of the wing blades 3 towards the mantle surface of the cone 2 can of course be varied to obtain the best effect for each area of use.

Förntom att vingbladens 3 utsträckning i rotatíonsaxelns längd- riktning kan varieras så kan naturligtvis även antalet vingblad 3 varieras. Om det ovan angivna villkoret skall gälla att vingbladen 3 skall täcka mantelytan, sett i rotationsaxelns riktning, så måste vingbladens 3 höjd öka om dess antal minskar och omvänt.Apart from the fact that the extent of the wing blades 3 in the longitudinal direction of the axis of rotation can be varied, the number of wing blades 3 can of course also be varied. If the above condition is to apply that the wing blades 3 are to cover the mantle surface, seen in the direction of the axis of rotation, then the height of the wing blades 3 must increase if its number decreases and vice versa.

Konen 2 kan vara öppen eller tillsluten vid sitt bottenparti.The cone 2 can be open or closed at its bottom part.

I fig. 4 visas en annan utföringsform av uppfinningen. Ving- bladen 3' uppvisar ej någon baksida utan de förlöper i en spiralformad, trappstegsliknande konfiguration. I Genom den i fig. 4 visade utformningen av vingbladen 3' förhind- ras virvelbildning på dessas baksida då vinden passerar förbi bladen 3.Fig. 4 shows another embodiment of the invention. The wing blades 3 'have no back side but run in a helical, step-like configuration. Due to the design of the wing blades 3 'shown in Fig. 4, vortex formation on their rear side is prevented as the wind passes the blades 3.

I fig. 4 syns även tydligt att horisontella linjer genom ving- bladens 3' spetsar träffar konens 2' mantelyta vid nästföljande blads anslutning till denna.In Fig. 4 it is also clear that horizontal lines through the tips of the wing blades 3 'hit the mantle surface of the cone 2' at the connection of the next blade to it.

I övrigt är luftturbinen 1' enligt fíg. 4 upphängd på samma sätt som luftturbinen 1 i fig. 1, dvs. ett i horisontalplanet svängbart lagrat hållarorgan 5' uppbär en axel 4', på vilken turbinen l' är roterbart lagrad.Otherwise, the air turbine is 1 'according to fig. 4 suspended in the same way as the air turbine 1 in Fig. 1, i.e. a holding member 5 'pivotally mounted in the horizontal plane carries a shaft 4', on which the turbine 1 'is rotatably mounted.

Genom den visade upphängningen kommer luftturbinen 1 och 1' all- 7803445-1 3 tid att ställa in sig med axlarna 4,4' i vindriktningen.Due to the suspension shown, the air turbine 1 and 1 'will always adjust with the shafts 4,4' in the wind direction.

Den i luftturbinen 1,1' ingående konen 2,2' kan, på grund av sin form, själv uppta stora påkänningar. Emellertid kan man även förstärka den från insidan på lämpligt sätt.The cone 2.2 'contained in the air turbine 1,1' can, due to its shape, itself absorb large stresses. However, it can also be reinforced from the inside in a suitable way.

När det gäller vingbladen, speciellt de enligt utföringsformen enligt fig. 1-3, så dimensioneras även de för att motstå de aktuella påkänningar som kan uppträda.In the case of the wing blades, especially those according to the embodiment according to Figs. 1-3, they are also dimensioned to withstand the actual stresses that may occur.

Uppfinningen är på intet sätt begränsad till de visade utförings- exemplen utan kan fritt varieras inom ramen för de efterföljande patentkraven. -__---~-.-_The invention is in no way limited to the exemplary embodiments shown, but can be freely varied within the scope of the following claims. -__--- ~ -.-_
