Abstract
Description
10 15 20 25 30 Le monde consomme de plus en plus d'énergie et il est clair qu'il nous faut polluer de moins en moins. II convient donc d'utiliser ces énergies appelées « renouvelables » parmi lesquelles le vent présente une disponibilité remarquable. Les éoliennes sont donc d'actualité avec une offre très vaste allant des plus petits modèles jusqu'aux projets d'implantation, terrestres ou offshore, qui son énormes. Généralement utilisées pour produire de l'électricité, elles servent également pour pomper des liquides ou comprimer des gaz. L'être humain a toujours utilisé le vent mais n'a pas toujours réussi à le dominer et à l'utiliser en permanence. Même actuellement certaines grandes éoliennes ont besoin d'un vent minimum, assez élevé, pour commencer à produire et, malheureusement, arrêtent de produire quand le vent devient trop fort pour elles. On peut trouver ça aberrant car il semble logique de produire beaucoup quand le vent est fort. C'est cette réflexion qui est à la base de l'invention objet de ce brevet. L'éolienne à axe vertical présente l'avantage d'utiliser le vent, quelque soit sa direction. Le rotor vertical, (voir planche 2) qui nous concerne pour ce brevet, est composé de deux ou plusieurs pales dont le profil est courbe donc présentant une partie convexe appelée r extrados et une partie concave appelée l'intrados. Ces pales sont fixées sur deux disques, l'un au dessus et l'autre au dessous, traversés par un axe vertical solidaire des disques. Selon la disposition de ses pales, il peut tourner dans un sens ou dans l'autre. La pression du vent exercée sur les pales lui présentant leur intrados est supérieure à celle exercée sur les pales lui présentant leur extrados ; ce qui fait que le rotor tourne sur lui-même autour de son axe. Une partie génère de la puissance mais l'autre est un frein. On comprend donc facilement que si on diminue ou si on annule la pression du vent sur les pales lui présentant leur extrados, on élimine ce frein et on augmente la puissance du rotor et sa vitesse de rotation. 35 10 15 20 25 30 The world is consuming more and more energy and it is clear that we have to pollute less and less. It is therefore appropriate to use these energies called "renewable" among which the wind has a remarkable availability. Wind turbines are therefore topical with a wide range of offerings ranging from smaller models to implementation projects, land or offshore, which are huge. Usually used to produce electricity, they are also used to pump liquids or compress gases. The human being has always used the wind but has not always managed to dominate it and use it constantly. Even now some large wind turbines need a minimum wind, high enough, to start producing and, unfortunately, stop producing when the wind becomes too strong for them. We can find this absurd because it seems logical to produce a lot when the wind is strong. It is this reflection that is the basis of the invention that is the subject of this patent. The vertical axis wind turbine has the advantage of using the wind, whatever its direction. The vertical rotor, (see plate 2) which concerns us for this patent, is composed of two or more blades whose profile is curved thus having a convex part called r extrados and a concave part called the intrados. These blades are fixed on two discs, one above and one below, crossed by a vertical axis secured discs. Depending on the arrangement of its blades, it can turn in one direction or the other. The pressure of the wind exerted on the blades presenting to him their intrados is greater than that exerted on the blades presenting to him their extrados; which makes the rotor turn on itself around its axis. One part generates power but the other is a brake. It is therefore easily understood that if we decrease or if we cancel the wind pressure on the blades presenting their extrados, we eliminate this brake and increases the power of the rotor and its speed of rotation. 35
L'invention objet de ce brevet consiste en un DISPOSITIF périphérique à un rotor vertical d'éolienne qui a pour but d'en optimiser le rendement par vent de force normale et de la protéger en cas de vent excessif mais sans la stopper pour qu'elle continue à produire. Le dispositif se veut simple car une éolienne travaille dans un environnement hostile, rayons UV du soleil, humidité, air salin et chargé de particules abrasives ce qui occasionne de l'usure et de l'oxydation donc des pannes qui impliquent des frais de maintenance. Donc, plus le dispositif est simple, plus il est fiable et moins il coûte. The invention which is the subject of this patent consists in a DEVICE peripheral to a vertical rotor of a wind turbine which aims to optimize its efficiency in normal force wind and to protect it in case of excessive wind but without stopping it so that she continues to produce. The device is simple because a wind turbine works in a hostile environment, UV rays of the sun, humidity, salt air and loaded with abrasive particles which causes wear and oxidation so breakdowns that involve maintenance costs. So, the simpler the device, the more reliable it is and the less it costs.
Ce dispositif convient à tout type d'éoliennes à axe vertical depuis celles de petite taille, pour des usagers particuliers, jusqu'à celles de très grandes dimensions pour une utilisation industrielle. This device is suitable for all types of vertical axis wind turbines, from small ones, for particular users, to very large ones for industrial use.
15 On considère une embase sur laquelle est fixé un moyeu lui-même traversé par l'axe vertical d'un rotor. Le dispositif se compose d'un support fixé sur l'axe du rotor, au dessus du disque supérieur et au dessous du disque inférieur. Sur ce support est fixé un déflecteur qui se positionnera en fonction de la 20 direction du vent, de sa puissance et de la vitesse de rotation du rotor grâce aux organes suivants : un aileron fixe, un contrepoids, un aileron réglable et un système centrifuge d'entraînement. We consider a base on which is fixed a hub itself traversed by the vertical axis of a rotor. The device consists of a support fixed on the axis of the rotor, above the upper disk and below the lower disk. On this support is fixed a deflector which will be positioned according to the wind direction, its power and the speed of rotation of the rotor through the following organs: a fixed fin, a counterweight, an adjustable fin and a centrifugal system. 'training.
Le support (S) du dispositif (planche 3) est composé de : Un ensemble rigide de tiges ou plaques (S1), fixées sur un palier monté sur l'axe vertical du rotor, et d'une couronne (S2), sur la partie supérieure dans l'exemple décrit. Sur la partie inférieure, dans l'exemple décrit, un ensemble rigide de tiges ou plaques fixées sur un palier monté sur l'axe vertical du rotor. Trois tiges verticales (S3) qui donnent sa rigidité au dispositif et qui supportent le déflecteur et les deux ailerons. 10 25 30 35 Une tige ou plaque (S4) qui supportera la vis de réglage de l'aileron réglable. Pour des rotors de petite taille il sera fixé sur l'axe vertical du rotor au moyen de roulements et/ou de paliers. Pour des rotors de diamètre plus important il pourra être fixé à la fois sur l'axe 5 vertical et/ou sur la périphérie du rotor. Le support permet au dispositif de se déplacer en rotation, librement, tout autour du rotor. The support (S) of the device (plate 3) is composed of: A rigid set of rods or plates (S1), fixed on a bearing mounted on the vertical axis of the rotor, and a ring (S2), on the upper part in the example described. In the lower part, in the example described, a rigid set of rods or plates fixed on a bearing mounted on the vertical axis of the rotor. Three vertical rods (S3) which give rigidity to the device and which support the deflector and the two fins. A rod or plate (S4) that will support the adjustable fin adjustment screw. For small rotors it will be fixed on the vertical axis of the rotor by means of bearings and / or bearings. For rotors of larger diameter it can be fixed both on the vertical axis and / or on the periphery of the rotor. The support allows the device to move in rotation, freely, all around the rotor.
Le déflecteur (planche 4) (D), pièce essentielle du dispositif, est une plaque 10 rigide, courbe ou galbée fixée sur les parties supérieure et inférieure du support de même hauteur que le rotor. De par sa largeur il masquera le rotor sur une partie de sa circonférence, d'un sixième à un tiers, en fonction du diamètre du rotor et du nombre de ses pales. La courbure et le galbe du déflecteur seront fonction du diamètre du rotor et du 15 nombre de ses pales. The deflector (plate 4) (D), essential part of the device, is a rigid plate 10, curved or curved fixed on the upper and lower parts of the support of same height as the rotor. Because of its width, it will mask the rotor over a part of its circumference, from one-sixth to one-third, depending on the diameter of the rotor and the number of its blades. The curvature and curvature of the deflector will be a function of the diameter of the rotor and the number of its blades.
Le déflecteur sera fixé au support de façon à ce que sa partie avant, appelée « bord d'attaque » (D1) soit proche du rotor mais sans le toucher tandis que sa partie arrière appelée « chute » (D2) en sera écartée de façon à former un 20 angle (D3) avec le bord du rotor qui sera plus ou moins important en fonction du diamètre du rotor et du nombre de ses pales. C'est grâce à cet angle et au galbe du déflecteur que la simple action du vent sur son intrados et son extrados fera qu'il se positionnera devant la partie du rotor où les pales présentent leur extrados au vent donc augmentera la 25 puissance du rotor. Le comportement du déflecteur est similaire à celui du spinnaker ou du kite. Il a tendance à osciller, c'est-à-dire a faire des va et vient d'un côté et de l'autre, en fonction des sautes de vent. II convient donc de le stabiliser au moyen de deux ailerons. 30 35 10 15 20 25 L'aileron fixe (planche 5) (AF) est un volet fixé sur le support plus ou moins à l'opposé du bord d'attaque du déflecteur; il est de la même hauteur que le déflecteur. Sa largeur et sa position peuvent varier en fonction du diamètre du rotor et du nombre de ses pales. La pression du vent qui s'exerce sur l'aileron fixe déplace le déflecteur vers la partie du rotor où les pales présentent leur intrados au vent et, par conséquent, diminuera la puissance du rotor et sa vitesse. The deflector will be fixed to the support so that its front part, called "leading edge" (D1) is close to the rotor but not touching it while its rear part called "fall" (D2) will be removed so to form an angle (D3) with the edge of the rotor which will be more or less important depending on the diameter of the rotor and the number of its blades. It is thanks to this angle and to the curve of the deflector that the simple action of the wind on its intrados and extrados will cause it to position itself in front of the part of the rotor where the blades present their extrados to the wind so will increase the power of the rotor . The behavior of the deflector is similar to that of the spinnaker or kite. It tends to oscillate, that is to say to go back and forth on one side and the other, depending on the wind changes. It is therefore necessary to stabilize it by means of two fins. The fixed wing (Plate 5) (AF) is a flap fixed on the support more or less opposite the leading edge of the baffle; it is the same height as the deflector. Its width and position may vary depending on the diameter of the rotor and the number of its blades. The wind pressure on the fixed fin displaces the deflector towards the part of the rotor where the blades have their intrados to the wind and, consequently, will decrease the power of the rotor and its speed.
L'AILERON REGLAELE (planche 5) L'aileron réglable (AR) est un volet fixé sur la chute du déflecteur (D2), au moyen d'une charnière (AR4); il peut donc osciller autour de cette charnière. Sa hauteur est celle du déflecteur et sa largeur dépend du diamètre du rotor et du nombre de ses pales. La pression du vent qui s'exerce sur l'aileron réglable est contraire à celle exercée sur l'aileron fixe (AF). Le réglage de cet aileron se fait au moyen d'un ensemble « vis écrou » fixé à une tige solidaire du support. Cette vis (AR1), qui supporte un ressort (AR3) et un écrou de réglage (AR2), traverse un orifice pratiqué dans l'aileron (AR) qui peut donc osciller légèrement sous l'action du vent, en comprimant le ressort réglé par l'écrou. C'est en agissant sur cet écrou qu'il est possible d'ajuster et de stabiliser l'ensemble du dispositif pour que le déflecteur se place automatiquement devant les pales rotor qui présentent leur extrados au vent et qu'il s'oriente en fonction des changements de direction du vent. THE REGULATED FIN (board 5) The adjustable fin (AR) is a flap fixed on the fall of the deflector (D2), by means of a hinge (AR4); he can therefore oscillate around this hinge. Its height is that of the deflector and its width depends on the diameter of the rotor and the number of its blades. The wind pressure on the adjustable fin is opposite to that on the fixed fin (AF). The adjustment of this fin is done by means of a set "screw nut" attached to a rod secured to the support. This screw (AR1), which supports a spring (AR3) and an adjusting nut (AR2), passes through a hole made in the fin (AR) which can therefore oscillate slightly under the action of the wind, compressing the set spring by the nut. It is by acting on this nut that it is possible to adjust and stabilize the entire device so that the deflector is automatically placed in front of the rotor blades that have their upper wind and that it is oriented changes in wind direction.
II reste maintenant à protéger l'éolienne en cas de vent excessif car elle se détériorera si elle tourne trop vite, si elle « s'emballe ». Le système centrifuge (planche 6) (C) a pour but de déplacer le déflecteur devant les pales du rotor qui présentent leur intrados au vent et, par conséquent, diminuer la puissance du rotor et sa vitesse.It remains now to protect the wind turbine in case of excessive wind because it will deteriorate if it turns too fast, if it "gets carried away". The purpose of the centrifugal system (Plate 6) (C) is to move the deflector in front of the rotor blades which have their underside to the wind and, consequently, to decrease the power of the rotor and its speed.
30 35 10 15 Il se compose d'un roulement à billes (Cl) contenu et fixé au moyen d'un axe (C2) dans l'évidement pratiqué dans l'extrémité d'une masse métallique (C3), dont la taille et le poids sont fonction du diamètre du rotor et du nombre de ses pale. L'autre extrémité de cette masse est traversée par un axe (C4), fixé sur le disque supérieur du rotor, autour duquel elle peut tourner librement. Le système devient actif quand la vitesse du rotor augmente excessivement. Dans ce cas la masse qui supporte le roulement à billes tend à s'écarter vers l'extérieur par à la force centrifuge. Plus le rotor tourne vite, plus la pression est forte et plus le roulement à billes, qui roule sur la couronne du support du déflecteur accentue sa pression et entraîne progressivement le dispositif dans le sens de sa rotation. Quand la vitesse du vent baisse, la vitesse du rotor descend également, la pression du roulement sur la couronne diminue et le dispositif reprend sa position originale. Selon le diamètre du rotor et le nombre de ses pales, il peut y avoir plusieurs systèmes centrifuges. 20 25 30 35 3/ It consists of a ball bearing (Cl) contained and fixed by means of an axis (C2) in the recess formed in the end of a metal mass (C3), whose size and the weight depends on the diameter of the rotor and the number of its blades. The other end of this mass is crossed by an axis (C4), fixed on the upper disk of the rotor, around which it can rotate freely. The system becomes active when the rotor speed increases excessively. In this case the mass which supports the ball bearing tends to deviate outwards by the centrifugal force. The faster the rotor rotates, the stronger the pressure and the more the ball bearing, which rolls on the crown of the deflector support increases its pressure and gradually causes the device in the direction of its rotation. When the wind speed drops, the rotor speed also drops, the bearing pressure on the crown decreases and the device returns to its original position. Depending on the diameter of the rotor and the number of its blades, there may be several centrifugal systems. 3 /
