Description
vsoßoseés 10 15 20 25 30 35 2 propeller har en äggliknande eller cylindrisk form. vsoßoseés 10 15 20 25 30 35 2 propellers have an egg-like or cylindrical shape.
Vissa längsgående blad är svängbart monterade på detta löphjul medelst klämmor, vilka blad är försedda med serier av skevningsroder, som sträcker sig i bla- dens tvärriktning. Dessa skevningsroder användes för att uppstöda bladen på löphjulets stomme, då bladen är i sin maximala operationsfas. Denna fas uppnås blott på det parti av löphjulet, där riktningen av rotations- rörelsen av bladet på sin led under verkan av centrifu- galkraften är densamma som vindriktningen.Some longitudinal blades are pivotally mounted on this impeller by means of clamps, which blades are provided with series of skew rudders, which extend in the transverse direction of the blades. These skew rudders are used to support the blades on the impeller body, as the blades are in their maximum operating phase. This phase is achieved only on the part of the impeller where the direction of the rotational movement of the blade on its joint under the action of the centrifugal force is the same as the wind direction.
Detta läge tenderar att vara det mellanliggande lä- get mellan det operativa och icke operativa läget av bladet, då skevningsrodrens tyngdpunkt rör sig närmare linjen, som är en förlängning av löphjulets radie, på grund av verkan av centrifugalkraften. I det fallet pla- ceras varje blad mot vindriktningen, varigenom den yta på bladet, som är vänd mot vinden, reduceras.This position tends to be the intermediate position between the operative and non-operative positions of the blade, as the center of gravity of the skew rudder moves closer to the line, which is an extension of the impeller radius, due to the action of the centrifugal force. In that case, each blade is placed against the wind direction, thereby reducing the surface of the blade facing the wind.
Ovannämnda vindmotor har vissa nackdelar, nämligen låg effektivitet, dynamisk obalans under operation, låg reaktionsförmåga vid igångsättning och är mycket kompli- cerad. Ändamålet med föreliggande uppfinning är att undan- röja ovannämnda nackdelar och åstadkomma en bättre vind- -motor. Detta ändamål uppnås medelst den i efterföljande patentkravs kännetecknande del närmare definierade konstruktionen.The above-mentioned wind engine has certain disadvantages, namely low efficiency, dynamic imbalance during operation, low reactivity at start-up and is very complicated. The object of the present invention is to obviate the above-mentioned disadvantages and to provide a better wind engine. This object is achieved by means of the construction further defined in the characterizing part of the appended claims.
Uppfinningen skall i det följande närmare beskrivas under hänvisning till bifogade ritningar, som visar ett utföringsexempel. Fig l visar i perspektiv en vindmotor enligt uppfinningen med blad med variabelt utförande.The invention will be described in more detail below with reference to the accompanying drawings, which show an exemplary embodiment. Fig. 1 shows in perspective a wind engine according to the invention with blades of variable design.
Fig 2 visar vindmotorn i vertikalsektion och åskådlig- gör två halvcylindriska blad. Fig 3 visar vindmotorns rörliga delar_ovanifrân. Fig 4 visar vindmotorn på sam- ma sätt som fig 2 och åskådliggör bladens tyngdpunkt och tryckcentrum under deras rotationsrörelse och fig 5 åskådliggör vindmotorns rotationskurva relativt vindhas- tigheten. vindmotorn enligt föreliggande uppfinning har en ver- 10 15 20 25 30 35 7806056-3 3 tikal axel l, som är monterad i en bärkonstruktion 2 medelst lager 3.Fig. 2 shows the wind motor in vertical section and illustrates two semi-cylindrical blades. Fig. 3 shows the moving parts of the wind engine from above. Fig. 4 shows the wind motor in the same way as Fig. 2 and illustrates the center of gravity and pressure center of the blades during their rotational movement and Fig. 5 illustrates the rotation curve of the wind motor relative to the wind speed. the wind motor according to the present invention has a vertical shaft 1, which is mounted in a support structure 2 by means of bearing 3.
Den vertikala axeln har vid sin övre del en serie horisontella armar 4, vilka är stelt fästa vid axeln.The vertical shaft has at its upper part a series of horizontal arms 4, which are rigidly attached to the shaft.
Vid ytteränden av varje arm är ett halvcylindriskt blad 5 svängbart förbundet med armen. Varje blad 5 är försett med en halvcirkulär platta 6 vid vardera änden.At the outer end of each arm, a semi-cylindrical blade 5 is pivotally connected to the arm. Each blade 5 is provided with a semicircular plate 6 at each end.
Varje blad kan svänga från ett vertikalt begynnelse- läge till ett yttre horisontellt läge med hjälp av en led 7.Each blade can pivot from a vertical initial position to an outer horizontal position by means of a joint 7.
Ett stopporgan 8 är monterat på varje blad 5, vilket förhindrar en indragning av bladet mot bärkonstruktionen 2, då bladet befinner sig mittemot denna.A stop means 8 is mounted on each blade 5, which prevents a retraction of the blade against the support structure 2, when the blade is opposite it.
Vindmotorn enligt uppfinningen arbetar på följande sätt.The wind engine according to the invention operates in the following manner.
Dâ vinden icke blåser befinner sig bladen 5 i verti- kalt läge. Så motorn rotera snart som vindhastigheten ökar börjar vind- (fig 4) på grund av vindtrycket, som ver- kar på de halvcylindriska bladen 5.When the wind is not blowing, the blades 5 are in the vertical position. So the engine rotates as soon as the wind speed increases, the wind starts (fig. 4) due to the wind pressure, which acts on the semi-cylindrical blades 5.
Under denna rotationsrörelse, som Vindmotorn utför under verkan av vinden med en med v betecknad hastighet, utsättes varje blads tyngdpunkt G för verkan av två kraf- ter, som samtidigt verkar i vertikalplanet, nämligen tyngdkraften Fg och centrifugalkraften Fc. Läget av bla- det bestämmes av dessa båda krafters resultant. Tryck- centrum P för varje blad 5 kommer att befinna sig en viss sträcka R från vindmotorns rotationsaxel. Ju högre vindhastigheten är desto längre är sträckan R, varigenom en långsam variation av vindens rotationshastighet be- stämmes.During this rotational movement, which the Wind Motor performs under the action of the wind at a speed denoted by v, the center of gravity G of each blade is exposed to the action of two forces acting simultaneously in the vertical plane, namely gravity Fg and centrifugal force Fc. The position of the blade is determined by the resultant of these two forces. The pressure center P for each blade 5 will be a certain distance R from the axis of rotation of the wind motor. The higher the wind speed, the longer the distance R, whereby a slow variation of the wind rotational speed is determined.
Sålunda ökar löphjulets diameter och begränsar rota- tionshastigheten, då motorkopplingen ökar. På detta sätt kan rotationsegenskapen effektivt bibehållas konstant även då kraftiga vindar påverkar bladen.Thus, the impeller diameter increases and limits the rotational speed, as the motor clutch increases. In this way, the rotation property can be effectively maintained constant even when strong winds affect the blades.
Vindmotorn enligt uppfinningen har följande fördelar.The wind engine according to the invention has the following advantages.
Den tillåter en konstant rotation under många olika vind- hastigheter och tillåter inställning av Vindmotorn till speciella lokala förhållanden genom motsvarande dimen- 780605643 4 sionering av konstruktionselementen. Den tillåter en säker operation under varierande vindtryck. Den är av enkelt utförande, så .att funktionsproblem undvikes och den medför hög effektivitet vid varje vindhastighet.It allows a constant rotation under many different wind speeds and allows the setting of the Wind Motor to special local conditions by corresponding dimensioning of the structural elements. It allows safe operation under varying wind pressures. It is of simple design, so that function problems are avoided and it results in high efficiency at each wind speed.
