Abstract
Description
453 115 _g- annat särskilt kännetecken för uppfinningen, en vinkelrätt mot kammarens symmetriaxel anordnad skärm avsedd att riktas tvärs vindriktningen för att tillvarata så mycket vindenergi som möjligt och för att gynna uppkomsten av tornadoströmningen. 453 115 _g - another special feature of the invention, a screen arranged perpendicular to the axis of symmetry of the chamber intended to be directed transversely to the wind direction in order to utilize as much wind energy as possible and to promote the emergence of the tornado flow.
Då två luftskikt glider mot varandra laddas dessa som bekant upp. För att hindra sådan uppladdning hos de uppfinningsenliga nedåt- och uppåtgående tornadoströmningarna innefattar anordningen enligt uppfinningen ett med kammarens symmetriaxel koncentriskt rör, som tätt ansluter till nämnda öppning och sträcker sig nedåt i kammaren till ungefär halva dess höjd. Detta är företrädesvis av ett elektriskt ledande material och är elektriskt isolerat från kammaren i övrigt.As two air layers slide against each other, these are charged, as is well known. To prevent such charging of the downward and upward tornado currents according to the invention, the device according to the invention comprises a tube concentric with the axis of symmetry of the chamber, which tightly connects to said opening and extends downwards in the chamber to about half its height. This is preferably of an electrically conductive material and is electrically insulated from the rest of the chamber.
Uppfinningen skall i det följande förklaras ytterligare med hänvisning till bifogade ritning på vilken fig 1 schematiskt och delvis i sektion visar en anordning enligt uppfinningen. Fig 2, visar likaså delvis i sektion ett alternativt utförande av en anordning enligt uppfinningen.I nämnda figurer har detaljer som återfinnsi båda figurerna erhållit lika hänvisningsbeteckningar.The invention will be further explained in the following with reference to the accompanying drawing, in which Fig. 1 schematically and partly in section shows a device according to the invention. Fig. 2 also shows, partly in section, an alternative embodiment of a device according to the invention. In said figures, details found in both figures have been given the same reference numerals.
På ritningen betecknar 1 en rotationssymmetrisk kammare med en vertikalt anordnad symmetriaxel. Kammaren är öppen upptill och har åtminstone en vindöppning 2 genom vilken vinden är ämnad att strömma in i kammaren 1. Enligt uppfinningen är kammarens vägg 3 utformad så att kammaren smalnar av nedåt och vindöppningen 2 är relativt kammarväggen 3 utformad så att det i kammaren 1 uppkommer en spiralformigt nedåtriktad strömning 4. Hos denna strömning är trycket på en viss nivå i kammaren 1 minst i centrum, dvs omkring symmetriaxeln men genom kammarens nedåt avsmalnande form ökar trycket ju längre ned i kammaren man befinner sig. Vid botten av kammaren tvingas strömningen 4 att vända och bilda en uppåtgående tornadoströmning 5 i centrum av den nedåtgående strömningen 4, detta på grund av den nämnda tryckfördelningen i denna. Att strömningen 4 blir nedåtriktad beror i det i fig 1 visade utförandet på att vindöppningen 2 pekar nedåt; i fig 2 uppnås motsvarande genom att 453 115 kammaren 1 är äggformad så att den genom vindöppningen 2 inkommande luftstrålen av kammarväggen avlänkas nedåt. Till vindöppningen kan lämpligen anslutas en vinduppfångande skärm 6. Energin i tornadoströmningen 5 tas tillvara med hjälp av en till kammarens 1 övre öppning anslutande turbin 7.In the drawing, 1 denotes a rotationally symmetrical chamber with a vertically arranged axis of symmetry. The chamber is open at the top and has at least one wind opening 2 through which the wind is intended to flow into the chamber 1. According to the invention, the wall 3 of the chamber is designed so that the chamber tapers downwards and the wind opening 2 is formed relative to the chamber wall 3 so that it arises in the chamber 1 a helical downward flow 4. In this flow the pressure at a certain level in the chamber 1 is at least in the center, ie around the axis of symmetry but through the downwardly tapering shape of the chamber the pressure increases the further down in the chamber one is. At the bottom of the chamber, the flow 4 is forced to turn and form an upward tornado flow 5 in the center of the downward flow 4, this due to the said pressure distribution therein. The fact that the flow 4 becomes downward in the embodiment shown in Fig. 1 is due to the fact that the wind opening 2 points downwards; in Fig. 2 the corresponding is achieved in that the chamber 1 is egg-shaped so that the air jet entering through the wind opening 2 is deflected downwards by the chamber wall. A wind-absorbing screen 6 can suitably be connected to the wind opening. The energy in the tornado flow 5 is utilized by means of a turbine 7 connecting to the upper opening of the chamber 1.
Det kan noteras att när tornadoströmningen 5 är fullt utbildad är den i viss mån självförsörjande. För detta ändamål finns vid botten av kammaren 1 en ventil 8 inrättad att öppnas när tornadoströmningen 5 är fullt utbildad för att styra intensiteten hos tornadoströmningen . Vid alltför kraftig lufttillförsel via ventilen 8 kommer tornadoströmningen 5 att störas så mycket att den slutligen upphön ventilen 8 tjänar då som ett medel att stoppa vindenergisystemet.It can be noted that when the tornado flow 5 is fully formed, it is to some extent self-sufficient. For this purpose, at the bottom of the chamber 1 there is a valve 8 arranged to open when the tornado flow 5 is fully formed to control the intensity of the tornado flow. In the event of an excessive supply of air via the valve 8, the tornado flow 5 will be disturbed so much that the finally raised valve 8 then serves as a means of stopping the wind energy system.
Det kan också noteras att turbinen genom sin placering tar tillvara energiinnehållet från såväl den nedåtriktade strömningen 4 som den genom ventilen 8 inkomande strömningen.It can also be noted that the turbine, through its location, takes advantage of the energy content from both the downward flow 4 and the flow entering through the valve 8.
Som inledningsvis nämnts uppkommer elektriska laddningar då två luftskikt glider mot varandra. Eftersom strömningen 5 har en avsevärd periferihastighet kommer den uppkomna laddningen att bli mycket kraftig och eftersom energi härvid tas från tornadoströmningen är laddningseffekten en icke önskad bieffekt.För att i möjligaste mån minska uppkomsten av laddningar är, som framgår av fig 2, ett med kammarens 1 symmetriaxel rör 9 anslutet till kammarens 1 övre öppning. Röret 9 sträcker sig nedåt i kammaren 1 till ungefär halva dess höjd. Röret 9 är företrädesvis av ett elektriskt ledande material och medelst en ring 10 av isolerande material isolerat från kammaren 1 i övrigt.As mentioned in the introduction, electrical charges arise when two air layers slide against each other. Since the flow 5 has a considerable peripheral velocity, the resulting charge will be very strong and since energy is taken from the tornado flow, the charging effect is an undesirable side effect. To reduce the occurrence of charges as much as possible, as shown in Fig. 2, one with the chamber 1 axis of symmetry tube 9 connected to the upper opening of the chamber 1. The tube 9 extends downwards in the chamber 1 to about half its height. The tube 9 is preferably of an electrically conductive material and by means of a ring 10 of insulating material insulated from the chamber 1 in general.
Genom den uppfinningsenliga anordningen åstadkommas ett vindenergisystem med högre verkningsgrad och lägre bygghöjd än hos jämförbara anordningar av känt slag.The device according to the invention provides a wind energy system with a higher efficiency and lower construction height than with comparable devices of known type.
