Abstract

The invention relates to a turbine blade wheel for small and average water depths, characterised by the association of: a water admission in the wheel obtained by means of multi-directional flaps (7) that incline and open in such a way as to enable the space between the blades to be 100 % filled; blades comprising a blade closing element (9) and a space (V) for the air to escape, such a closing element enabling the pressurisation (P) of the wheel, eliminating the air pockets, without any overflow inside the wheel; and a lower fixed corridor for ensuring tightness beneath the wheel with a minimum amount of play in order to maintain the pressure (P) constant during the rotation of the wheel. Said association leads to a novel concept for a so-called pressure wheel that operates only as a result of the pressure exerted on the blades with a 100 % filling of the space between the blades.

ROUE à AUBES à PRESSION WHEEL IN AUBES PRESSURE
Domaine technique de l'inventionTechnical field of the invention
La présente invention est relative à des roues hydrauliques à aubes, un dis- positif qui utilise l'énergie potentielle et dynamique de l'eau des cours d'eau et des marées de toutes natures pour la transformer en énergie mécanique et ou en électricité. Etat de la techniqueThe present invention relates to hydraulic paddle wheels, a device that uses the potential and dynamic energy of water streams and tides of all kinds to transform it into mechanical energy and or electricity. State of the art
Les roues existantes jusqu'à ce jour, d'utilisation de l'énergie de l'eau dans le sens naturel du courant, sont des roues à aubes assemblées sur un châssis tournant constitué de disques avec des rayons de maintient jusqu'à l'axe de rotation, l'eau pénètre par dessous ou sur le coté avec des vannages d'admission , les aubes ouvertes du coté de l'entrée d'eau sont aussi ouvertes du coté intérieur de la roue. Différents types ont vu le jour au 19ième siècle parmi les plus notables les roues Poncelet et Sagebien en France et la roue Zuppinger en Allemagne, dans toutes ces roues qui s'inscrivent dans le flux d'eau avec une admission latérale, les débits entrant sont faibles et les vitesses très lentes car adaptées au dessin des aubes de la roue afin de maintenir un équilibre hydraulique sans chocs et sans débordements vers l'intérieur, ce qui limite considérablement leurs débits raison essentielle qui a conduit à leur abandon à la fin du 19ième siècle au profit des turbines.The existing wheels to date, using the energy of the water in the natural direction of the current, are paddle wheels assembled on a rotating frame consisting of discs with spokes of maintains up to the axis of rotation, water enters from below or on the side with inlet valves, the blades open on the side of the water inlet are also open on the inner side of the wheel. Various types emerged in the 19th century among the most notable Poncelet and Sagebien wheels in France and the Zuppinger wheel in Germany, in all these wheels that fit into the stream of water with a lateral admission, inflows coming in are low and very slow speeds because adapted to the design of the vanes of the wheel to maintain a hydraulic balance without shocks and without overflows inward, which significantly limits their flows essential reason that led to their abandonment at the end of the 19th century in favor of turbines.
Dans toutes ces roues le remplissage des aubes est très partiel de l'ordre au plus de 30% du volume disponible entre les aubes. Aucune roue au fil de l'eau, à aubes traditionnelle, sans possibilité de débordement intérieur et à remplissage à 100% , n'a été conçue à ce jour.In all these wheels the blade filling is very partial of the order at most 30% of the available volume between the blades. No run-of-the-river, traditional paddle wheel, with the possibility of overflow and 100% filling, has been designed to date.
La présente ROUE TURBINE à AUBES adapte la roue à aubes traditionnelle avec un dessin d'aubes qui interdit tout débordement de l'eau vers l'intérieur permettant des rotations à des vitesses élevées et le remplissage sans con- trainte de la totalité du vide entre les aubes, les débits passants, par ces deux facteurs , sont beaucoup plus élevés et rend les roues à aubes comparables, en matière de performances, aux turbines.The present TURBINE WHEEL in AUBES adapts the traditional impeller with a vane design that prevents overflow of the water inwards allowing rotations at high speeds and the uncompressed filling of the entire vacuum between the blades, the flow rates, by these two factors, are much higher and makes the impellers comparable in performance to the turbines.
Le remplissage de l'eau se fait par l'intermédiaire d'un distributeur amont constitué de volets orientables de façon à ne pas avoir de chocs de la veine d'eau entrante sur la roue ce permet d'utiliser la totalité de l'énergie potentielle de hauteur entre les niveaux amont et aval de la rivière et de fonctionner en pression, l'énergie potentielle est transformée en en énergie mécanique. DescriptionThe filling of the water is done by means of an upstream distributor consisting of adjustable shutters so as not to have shocks of the incoming water vein on the wheel it allows to use the totality of the energy potential height between the upstream and downstream levels of the river and operate in pressure, the potential energy is transformed into mechanical energy. Description
La présente invention concerne une roue hydraulique à aubes qui utilise l'énergie potentielle et dynamique de l'eau des cours d'eau et des marées pour la transformer en énergie mécanique laquelle peut être transformée en électrici- té, elle se compose :The present invention relates to a paddlewheel which uses the potential and dynamic energy of the water of rivers and tides to transform it into mechanical energy which can be converted into electricity, it is composed of:
- d'une partie mobile tournante dite rotor (1) constituée par des aubes(4) maintenus par des disques (3) les disques sont reliés à l'arbre (A) par des rayons (2) de forme et de nombre variable en fonction des efforts à transmettre, l'arbre tournant est maintenu en ses extrémités par des roulements tenus par des boî- tiers , un à chaque extrémité.- Of a rotating mobile part called rotor (1) constituted by blades (4) held by disks (3) the disks are connected to the shaft (A) by radii (2) of variable shape and number in According to the forces to be transmitted, the rotating shaft is held at its ends by bearings held by casings, one at each end.
- d'un couloir inférieur (5) d'une largeur minimum égale à l'espacement de deux aubes successives afin de maintenir en permanence une pression de poussée (P) derrière les aubes, pour maintenir cette pression il faut toujours au moins une aube sur le couloir (5) avec des jeux réduits comparables au jeu des turbines.- A lower corridor (5) of a minimum width equal to the spacing of two successive blades in order to maintain a constant pressure (P) behind the blades, to maintain this pressure must always at least one blade on the corridor (5) with reduced games comparable to the game of turbines.
- d'un distributeur amont (6) composés de plusieurs volets orientables (7).- An upstream distributor (6) composed of several adjustable flaps (7).
Pour une bonne compréhension, l'innovation est décrite ci-après par les figures 1 à 3 La figure 1 représente la vue générale d'ensemble en coupe transversale d'une roue prise comme exemple et qui comprends :For a good understanding, the innovation is described hereinafter in FIGS. 1 to 3. FIG. 1 represents the overall cross-sectional overview of a wheel taken as an example and which comprises:
- La partie tournante (1) composée de l'arbre porteur tournant (A) - des rayons (2) - des disques (3) - des aubes (4), dans l'exemple présenté le nombre d'aubes est égal à 16 mais ce nombre peut être plus ou moins important en fonction des dispositions géométriques qui peuvent varier en fonction des caractéristiques des sites à équiper, cette partie tournante pour la partie située entre le niveau amont et le niveau aval est entièrement dans l'eau- The rotating part (1) composed of the rotating bearing shaft (A) - spokes (2) - discs (3) - blades (4), in the example presented the number of blades is equal to 16 but this number may be more or less important depending on the geometric arrangements that may vary depending on the characteristics of the sites to be equipped, this rotating part for the part located between the upstream level and the downstream level is entirely in the water
- Le couloir inférieur (5) partie fixe d'une largeur au moins équivalente à un espacement entre deux aubes afin de maintenir la pression (P) induite par la hauteur (H) différence des niveaux de l'eau entre l'amont et l'aval. Lorsque l'aube sort du couloir la pression P disparaît, cette pression a été récupérée par la roue et transmise à l'arbre (A) pour une utilisation mécanique ou énergétique. H s'agit ainsi d'une roue dite à pression qui fonctionne uniquement par la pression (P) au niveau du couloir (5) et dont l'énergie est libérée lorsque la pression P disparaît avec l'échappement de l'aube.- The lower corridor (5) fixed part of a width at least equivalent to a spacing between two blades to maintain the pressure (P) induced by the height (H) difference in water levels between upstream and downstream. 'downstream. When the dawn leaves the corridor the pressure P disappears, this pressure was recovered by the wheel and transmitted to the shaft (A) for mechanical or energetic use. This is a so-called pressure wheel that operates only by the pressure (P) at the corridor (5) and whose energy is released when the pressure P disappears with the exhaust of the blade.
- Le distributeur (6) composé de volets orientables (7), dans le cas présent au nombre de quatre - la figure 1 les représentent dans une position d'admission d'eau dans la roue et la figure 2 dans une position fermée, dans ce cas l'eau ne pénètre plus dans la roue et la roue ne fonctionne plus.- The dispenser (6) consisting of adjustable flaps (7), in this case four in number - Figure 1 represent them in an admission position water in the wheel and Figure 2 in a closed position, in this case the water no longer enters the wheel and the wheel no longer works.
Ce distributeur bloque l'admission directe de la veine d'eau dans la roue source de chocs et de reflux, réparti la veine d'eau, oriente les flux d'eau, et rè- gle les débits et vitesses permettant ainsi le remplissage optimum de la roue.This distributor blocks the direct entry of the water vein into the source wheel of shock and ebb, distributes the water vein, orients the water flows, and regulates the flow rates and speeds thus allowing optimum filling. of the wheel.
La trajectoire des aubes n'utilise qu'un volume cylindrique extérieur restreint qui laisse parfaitement libre le volume intérieur dans lequel peut être implanté des arbres de diamètre adapté aux longueurs à franchir.The trajectory of the blades uses only a small external cylindrical volume which leaves perfectly free the interior volume in which can be implanted trees of diameter adapted to the lengths to be crossed.
La forme générale est cylindrique et de toutes longueurs - pour de grandes longueurs des rayons intermédiaires seront nécessaires.The general shape is cylindrical and of all lengths - for long lengths of intermediate radii will be necessary.
La figure 3 montre plus précisément la forme de la section de ces aubes constituée de deux parties : une partie courbe principale (8) dont la fonction est de recevoir le flux d'eau entrant en le déviant vers le haut de l'aube afin d'éliminer les chocs source de pertes et une partie droite (9) de liaison entre deux aubes successives, cette liaison d'aube à aube ferme les aubes vers l'intérieur de la roue et interdit ainsi toute pénétration de l'eau à l'intérieur de la roue ce qui permet le remplissage et la mise en pression (P) par la hauteur d'eau - la courbure des aubes, associée à la répartition et à l'orientation de l'eau entrante donnée par les volets (7), est telle qu'il n'y a pas de choc du flux d'eau entrant sur cette paroi arrière ainsi constituée.FIG. 3 shows more precisely the shape of the section of these blades consisting of two parts: a main curved part (8) whose function is to receive the flow of incoming water by deflecting it towards the top of the blade in order to eliminating shocks source of losses and a straight part (9) of connection between two successive blades, this blade vane connection closes the vanes towards the inside of the wheel and thus prevents any penetration of water to the inside the wheel which allows the filling and the pressurization (P) by the height of water - the curvature of the blades, associated with the distribution and orientation of the incoming water given by the flaps (7) , is such that there is no shock of the flow of water entering the rear wall thus formed.
Le détail d'assemblage (D) montre qu'un vide (V) est réservé afin de permettre à l'air de s'échapper lors des remplissages et d'éviter des phénomènes de succion lors de l'évacuation de l'eau, l'échappement de l'air reste un problème majeur en hydraulique lorsqu'il y a remplissage ou évacuation, c'est ce vide d'air associé aux volets d'admission et à leur orientation qui permet le remplissage optimum de la roue nécessaire pour un fonctionnement en pression.The assembly detail (D) shows that a vacuum (V) is reserved to allow the air to escape during refilling and to avoid suction phenomena during the evacuation of water, the exhaust air remains a major problem in hydraulics when filling or evacuation, it is this air vacuum associated with the intake flaps and their orientation that allows the optimum filling of the wheel necessary for pressure operation.
Les aubes sont assemblées en leur extrémités sur les disques minces circulaires (3) par l'intermédiaire de raidisseurs latéraux boulonné sur les disques. NOUVEAUTE : la nouveauté, pour des roues au fil de l'eau, est consti- tuée par l'association :The blades are assembled at their ends on the circular thin discs (3) via lateral stiffeners bolted to the discs. NEW: the novelty, for wheels on the water, is constituted by the association:
- de la forme des aubes qui permet de maintenir l'eau à l'intérieur de la roue sans possibilité de débordement intérieur,- The shape of the blades that keeps the water inside the wheel without the possibility of internal overflow,
- du couloir inférieur (5) fixe qui assure l'étanchéité inférieure de la roue afin de mobiliser la pression (P) issue de l'énergie potentielle de la hauteur H, - du distributeur (6) qui, par la distribution et l'orientation donnée au flux d'eau, permet le remplissage optimum de la roue afin de lui permettre de travailler en pression en maîtrisant l'introduction de l'eau dans la roue en direc - tion et en vitesse afin d'éviter tout phénomène de chocs, qui reste le problème majeur de toute introduction d'un fluide dans une structure tournante.- The lower corridor (5) fixed which ensures the lower seal of the wheel to mobilize the pressure (P) from the potential energy of the height H, - the distributor (6) which, by the distribution and the orientation given to the flow of water, allows the optimum filling of the wheel to enable it to work in pressure by controlling the introduction of water into the wheel in direc - tion and speed to avoid any shock phenomenon, which remains the major problem of any introduction of a fluid in a rotating structure.
C'est cette association qui permet un fonctionnement en pression avec un remplissage total du vide disponible entre les aubes Cette conception de remplissage par distributeur présente plusieurs intérêts :It is this combination that allows a pressure operation with a total filling of the available vacuum between the blades. This filling design by distributor has several interests:
- elle permet le remplissage du volume entre les aubes à 100% avec échappement de l'air.- It allows the filling of the volume between the blades to 100% with exhaust air.
- elle permet une profondeur de l'aube jusqu'à des valeurs de l'ordre du quart du diamètre de la roue , proportion inconnue à ce jour qui permet pour un même débit utilisable des roues de dimensions réduites.- It allows a depth of the blade up to values of the order of a quarter of the diameter of the wheel, unknown proportion to this day which allows for a similar usable flow of small size wheels.
- du fait de la conception hydraulique d'élimination des chocs elle permet des vitesses de rotation beaucoup plus élevées que celles des roues anciennes.- Due to the hydraulic design of shock elimination it allows speeds of rotation much higher than those of old wheels.
- l' association de vitesses plus élevées, de profondeur d'aube plus importantes et de remplissage à 100% a pour conséquence des débits utilisables pour un même encombrement extérieur plus de 5 fois supérieur aux roues de conception anciennes.- the combination of higher speeds, greater blade depth and 100% filling results in usable flow rates for the same external footprint more than 5 times higher than the old design wheels.
- la conséquence est de permettre des puissances comparables à celles des turbines ce qui permet de replacer la roue à aube avec ses propres avantages de simplicité et de non impacts négatifs sur la faune aquatique constaté pendant des centaines d'années sur tous les continents- the consequence is to allow powers comparable to those of the turbines which makes it possible to replace the impeller with its own advantages of simplicity and not negative impacts on the aquatic fauna found during hundreds of years on all the continents
- c'est une forme traitée en deux dimensions ce qui simplifie considérablement les études de recherches et la fabrication -- it is a form treated in two dimensions which considerably simplifies the studies of researches and the manufacture -
- le volume global mobile est cylindrique ce qui permet à l'ensemble de s'inscrire dans un canal simple ce qui réduit de façon considérable les amé- nagements extérieurs nécessaires habituellement pour les turbines de moyenne et basses chutes.the overall moving volume is cylindrical, which allows the assembly to fit into a single channel, which considerably reduces the external arrangements usually required for medium and low-pressure turbines.
Les dimensions géométriques peuvent être très variables : le diamètre hors tout de la roue, sa largeur, la profondeur des aubes et la hauteur de retenue de l'eau sont directement liés aux paramètres d'utilisation de la rivière ou des réservoirs d'eau, les hauteurs de chutes pouvant être pour les plus basses de l'ordre de 10m, jusqu'à des hauteurs de plusieurs centaines de m. Les seules limitations du dispositif sont imposées par les contraintes de tenue mécanique et de précision de fabrication des différents matériaux mis en oeuvre. Dans l'exemple représenté par les figures 1 à 3 :The geometric dimensions can be very variable: the overall diameter of the wheel, its width, the depth of the blades and the height of water retention are directly related to the parameters of use of the river or water tanks, the heights of falls can be for the lowest of the order of 10m, up to heights of several hundred meters. The only limitations of the device are imposed by the constraints of mechanical strength and manufacturing precision of the different materials used. In the example represented by FIGS. 1 to 3:
- le diamètre de la roue est de 4m- the diameter of the wheel is 4m
- la profondeur des aubes est de 100cm - la largeur prise comme exemple est de 200cm- the depth of the blades is 100cm - the width taken as an example is 200cm
- la hauteur H de la retenue d'eau est de 200cm- the height H of the water reservoir is 200cm
La vitesse de la roue sera de l'ordre de 3m/ sec en périphérie ( 0,5 rati- ne(2x9,81xH) soit de l'ordre de 14tours/mn Le débit sera de l'ordre de 4,5m3/secThe speed of the wheel will be of the order of 3m / sec at the periphery (0.5 rati (2x9.81xH), ie of the order of 14rpm. The flow rate will be of the order of 4.5m3 / sec.
La puissance produite à la sortie du générateur sera de l'ordre de (4, 5m3/ sec)x(2m)x(7) soit de l'ordre de 6OkW - ce qui est très important pour un encombrement de cet ordre et comparable aux performances des turbines. INVENTIVITE Les roues à aubes existent depuis des milliers d'années, au 19ième siècle de nombreuses études ont été faites pour les perfectionner : les roues Poncelet - Sagebien - Zuppinger toutes sont des roues à vitesses lente car toutes confrontées à la problématique de l'admission d'une veine d'eau dans une structure tournante et aux débordement d'eau à l'intérieur de la roue - depuis quelques années des concepts de roues à pression ont vu le jour mais sont toutes restées confrontées à cette même problématique qui leur interdit de fait un remplissage à 100%.The power produced at the output of the generator will be of the order of (4, 5m3 / sec) x (2m) x (7) is of the order of 6OkW - which is very important for a congestion of this order and comparable turbine performance. INVENTIVITY Paddle wheels have existed for thousands of years, in the 19th century many studies have been made to perfect them: the wheels Poncelet - Sagebien - Zuppinger all are slow speed wheels because all face the problem of admission a vein of water in a rotating structure and overflow of water inside the wheel - in recent years concepts of pressure wheels have emerged but all have remained confronted with the same problem that prevents them in fact a 100% filling.
L'inventivité est essentiellement constituée par l'admission de l'eau dans la structure tournante d'une roue à aubes par des volets orientables, solution de remplissage qui n'a jamais été envisagé à ce jour, cette solution, par les débits passant important qu'elle permet, replace la roue à aubes dans les techniques de production d'énergie hydraulique performantes avec tous ses avantages de simplicité et écologiques constatés sur des centaines d'années.The inventiveness is essentially constituted by the admission of water into the rotating structure of a paddle wheel by means of adjustable flaps, filling solution which has never been envisaged to date, this solution, by the flow rates important that it allows, replace the impeller in the techniques of efficient hydropower generation with all its advantages of simplicity and ecological found over hundreds of years.
INDUSTRIALISATIONINDUSTRIALIZATION
La fabrication générale des éléments, y compris celle des aubes, du fait de leur forme, est très simple et économique.The general manufacture of the elements, including that of the blades, because of their shape, is very simple and economical.
L'assemblage de l'ensemble peut parfaitement être réalisé sur les sites eux- mêmes.
