La présente invention concerne un dispositif pour dégager les déchets obstruant la grille d'admission d'eau d'une turbine hydraulique. The present invention relates to a device for releasing waste obstructing the water intake grid of a hydraulic turbine.
La désobstruction de ces grilles est traditionnellement effectuée manuellement à l'aide d'un racleur ou d'un râteau. The unblocking of these grids is traditionally carried out manually using a scraper or a rake.
Certaines centrales sont équipées de bras hydrauliques. Le coût élevé de ces installations dissuade la majorité des propriétaires de micro centrale. Some power plants are equipped with hydraulic arms. The high cost of these facilities dissuades the majority of micro power plant owners.
Un autre système consiste à racler les grilles au moyen du principe de l'épandeur à fumier. Une partie de la mécanique de guidage est immergée et se trouve ainsi exposée au sable, gravillons, branchages et autres qui provoquent de nombreux blocages et une usure rapide des éléments mécaniques. Another system consists of scraping the grates using the principle of the manure spreader. Part of the guide mechanism is submerged and is thus exposed to sand, gravel, branches and others which cause numerous blockages and rapid wear of the mechanical elements.
Le dispositif suivant l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.
Il comporte en effet un module linéaire monté sur un axe réglable permettant un mouvement pendulaire dont seul le bras en acier inoxydable et le racleur en plastique ou en bois sont immergés. Les mouvements sont donnés par la combinaison de la traction d'un treuil (pignon crémaillère ou galet entraîneur), d'une bague buttée réglable, de la force de gravitation et d'une glissière de levage. Cet ensemble permet un raclage devant la grille et de la grille. Il permet également une adaptabilité à chaque site grâce à ses portiques permettant les réglages aisés horizontalement et verticalement de l'axe et de la glissière. L'armoire électrique se réduit à une protection moteur et à un programmateur. Le tout avec une grande simplicité et fiabilité mécanique d'où un coût et une maintenance très inférieure aux autres systèmes. It indeed comprises a linear module mounted on an adjustable axis allowing a pendulum movement of which only the stainless steel arm and the plastic or wooden scraper are immersed. The movements are given by the combination of the pull of a winch (rack pinion or driving roller), an adjustable butted ring, the force of gravity and a lifting slide. This set allows scraping in front of the grid and the grid. It also allows adaptability to each site thanks to its gantries allowing easy adjustments horizontally and vertically of the axis and the slide. The electrical cabinet is reduced to an engine protection and a programmer. All with great simplicity and mechanical reliability, hence a cost and maintenance much lower than other systems.

Dans la position (1), le module est à l'arrêt pendant un laps de temps plus ou moins long suivant la période de l'année. In position (1), the module is stopped for a longer or shorter period depending on the time of the year.
Au démarrage du module, le bras (6) entraîné par le treuil (15) et le câble (7), le racleur (2) racle le fond (3) du cours d'eau devant la grille (4), puis la grille (4) en remontant. A l'arrivée du racleur (2) au niveau de la glissière (5), le module remonte en pivotant sur l'axe (11) par le fait de l'inclinaison de la glissière (5) puis bascule par contrepoids et se met en buttée sur la pièce (23) par l'intermédiaire de la pièce (24). La buttée mobile (25) se glisse sous la buttée fixe (23) en pivotant sur son axe (27) sous l'effet de la traction du ressort (28). Elle se met en buttée sur la pièce (26) en position de verrouillage du basculement du module (10). En bout de course haute, le bras (6) muni d'une pièce (19) arrête le treuil (15) en se mettant en contact avec la buttée de fin de course (16). Le bras (10) se met à descendre sous l'effet de la gravité et bascule pour se mettre en contact sur la buttée mobile (25). Dans cette position de descente, le racleur (2) est tenu à l'écart de la grille (4). Arrivé en bout de course basse le bras (6) muni d'un poussoir (29) fait pivoter la buttée mobile (25) libérant le mouvement pendulaire du module et remet ainsi le racleur (2) en position (1). When the module starts, the arm (6) driven by the winch (15) and the cable (7), the scraper (2) scrapes the bottom (3) of the stream in front of the grid (4), then the grid (4) going up. At the arrival of the scraper (2) at the level of the slide (5), the module rises by pivoting on the axis (11) by the fact of the inclination of the slide (5) then rocks by counterweight and starts abutting on the part (23) via the part (24). The movable abutment (25) slides under the fixed abutment (23) by pivoting on its axis (27) under the effect of the traction of the spring (28). It abuts on the part (26) in the module tilting locking position (10). At the high end of travel, the arm (6) provided with a part (19) stops the winch (15) by coming into contact with the end of travel abutment (16). The arm (10) begins to descend under the effect of gravity and switches to come into contact on the mobile abutment (25). In this lowering position, the scraper (2) is kept away from the grid (4). Arrived at the lower end of the stroke the arm (6) provided with a pusher (29) rotates the mobile abutment (25) releasing the pendulum movement of the module and thus returns the scraper (2) to position (1).
En référence à ces dessins, le dispositif comporte - un bras (6) en forme de tube rectangulaire comportant : - un racleur (2) glissant sur le fonds (3), la grille (4) puis la glissière (5). Les pointillés (30) et (31) représentent deux exemples de circuit du racleur (2) au point (32). With reference to these drawings, the device comprises - an arm (6) in the form of a rectangular tube comprising: - a scraper (2) sliding on the bottom (3), the grid (4) then the slide (5). The dotted lines (30) and (31) represent two examples of the circuit of the scraper (2) at point (32).
- une platine (21) pour sa fermeture avec un perçage (20) d'admission d'eau régulant sa descente. - a plate (21) for its closure with a bore (20) for water intake regulating its descent.
- une pièce (19) qui en se mettant en contact avec la buttée (16) de fin de course arrête le treuil (15). - A part (19) which by coming into contact with the end stop (16) stops the winch (15).
- un câble (7) fixé à son extrémité inférieure permet sa remontée en s'enroulant sur le treuil (15) et en coulissant de ce fait dans la coulisse (10). - A cable (7) fixed at its lower end allows its ascent by winding on the winch (15) and thereby sliding in the slide (10).

- une buttée mobile (25) pivotant sur son axe (27) fixé à la coulisse (10) et tirée par le ressort (28). - A mobile stop (25) pivoting on its axis (27) fixed to the slide (10) and pulled by the spring (28).
- un axe (11) fixé à ses extrémités dans les coulisseaux (18). - an axis (11) fixed at its ends in the slides (18).
- une bague buttée (22) réglable sur l'axe (11) par des vis pointeaux, une barre de positionnement (23) est soudée sur celle-ci. - a butted ring (22) adjustable on the axis (11) by needle screws, a positioning bar (23) is welded thereon.
- deux glissières (5) réglables sur le portique (8) contraignent le module linéaire à remonter par le contact du racleur (2). - two slides (5) adjustable on the gantry (8) force the linear module to go up by the contact of the scraper (2).
- deux portiques (8) en tube carré ou rectangulaire fixés au sol munis de : - deux coulisses (17) permettant le réglage vertical de l'axe (11) - deux coulisses (14) - deux coulisseaux (18) permettant le réglage horizontal de l'axe (11). - two gantries (8) in square or rectangular tube fixed to the ground provided with: - two slides (17) allowing the vertical adjustment of the axis (11) - two slides (14) - two slides (18) allowing the horizontal adjustment of the axis (11).
A titre d'exemples non limitatifs, le bras (6) a une longueur d'environ trois mètres et le racleur (2) une largeur d'environ deux mètres. By way of nonlimiting examples, the arm (6) has a length of around three meters and the scraper (2) a width of around two meters.
