Description
Groupe électrogène hydraulique à axe vertical du type en parapluie. La présente invention concerne un groupe électrogène à turbine hydraulique à axe ver tical, du type constructif dit en parapluie, c'est-à-dire dans lesquels les parties rotatives de la turbine et du générateur électrique sont montées sur un arbre porté par un palier de butée monté au-dessous de la machine supé rieure et tournant dans deux paliers de gui dage.
La présente invention permet de réaliser d'importantes simplifications de construction et d'exploitation de ces groupes électrogènes par rapport aux réalisations connues et de réduire par rapport à celles-ci l'encombrement des groupes et, de ce fait, de réduire dans une certaine mesure les travaux de génie civil né cessaires pour les fondations et les bâtiments.
Le groupe électrogène selon l'invention se distingue des groupes connus par le fait que le palier de butée et le palier de guidage su périeur sont portés par un support commun reposant sur une bâche d'un distributeur de la turbine et par le fait que le moyeu du rotor du générateur électrique est assemblé au cylindre d'un servomoteur de réglage de la turbine, ce cylindre reposant par l'inter médiaire d'un manchon sur le palier de butée.
Le dessin annexé montre schématiquement et à titre d'exemple deux formes d'exécution du groupe électrogène, objet de l'invention.
Le groupe électrogène représenté comporte un alternateur 1 du type parapluie et une turbine 2 du type Kaplan. La partie tournante du groupe est guidée par deux paliers 3 et 4 et supportée par une butée 5.
Dans l'exemple de la fig.1, le palier de guidage 4 de la machine supérieure, c'est- à-dire de la génératrice électrique, prend appui directement sur l'arbre. Ce palier de guidage et la butée 5 sont portés par un support com mun 6, solidaire du couvercle 7 qui repose sur la bâche de distribution de la turbine. Le manchon tournant 8 repose sur la par tie tournante de la butée 5 et fait corps avec le cylindre 9 du servomoteur Kaplan, et cette pièce est prévue pour être accouplée, à sa partie intérieure, à l'arbre 10 de la turbine, par une bride circulaire 11 et à sa partie ex térieure au moyeu 12 de l'alternateur, par la bride 13.
Le moyeu 12 de l'alternateur a une forme appropriée à son accouplement à la bride 13 et dans le but de rapprocher le plus possible le centre de gravité du rotor de l'al ternateur du plan d'action du palier de gui dage 4, ce moyeu 12 entoure en grande partie le palier de butée 5, ce qui conduit à un gain important sur l'encombrement du groupe en hauteur. Le cylindre 9 du servomoteur porte à sa périphérie extérieure le collecteur à ba gues 14 d'amenée de courant d'excitation au rotor de l'alternateur.
Le support 6 du palier de butée sert égale ment d'appui aux vérins de levage 1.5 atta- quant le rotor de l'alternateur par son moyeu 12.
L'alternateur 1 est ainsi libéré de toute charge importante. Il ne comporte ni croisil lon inférieur ni consoles support de vérins, et son croisillon supérieur 16 ne sert que de plancher de fermeture et de support de la tête de réglage Kaplan, non représentée sur la figure. Le croisillon 16 porte également les vérins de freinage 17 attaquant le rotor de haut en bas.
Dans la variante de la fig. 2, le palier su périeur de guidage 4' prend appui sur la par tie tournante de cette butée.
Le manchon tournant 8 reposant sur la partie tournante de la butée 5 fait corps, comme dans l'exemple de la fig.1, avec le cy lindre 9 du servo--moteur Kaplan et est prévu pour être accouplé, par la bride 11, à l'arbre 10 de la turbine, et par la bride 13, au moyeu 12 de l'alternateur;
celui-ci reste au-dessus du palier de butée 5, la réduction du groupe en hauteur qui, dans le cas de la fig.1, provenait de ce que le moyeu 12 entourait le palier de butée 5, est ici réalisée du fait que c'est sur la partie tournante de cette butée 5 que prend appui le palier de guidage 4'.
Umbrella type vertical axis hydraulic generator. The present invention relates to a hydraulic turbine generator set with a vertical axis, of the so-called umbrella constructive type, that is to say in which the rotating parts of the turbine and of the electric generator are mounted on a shaft carried by a bearing stopper mounted below the upper machine and rotating in two guide bearings.
The present invention makes it possible to achieve significant simplifications in the construction and operation of these generator sets compared to known embodiments and to reduce the size of the groups in relation to them and, therefore, to reduce to a certain extent. measures the civil engineering work required for foundations and buildings.
The generator set according to the invention differs from known groups by the fact that the thrust bearing and the upper guide bearing are carried by a common support resting on a cover of a distributor of the turbine and by the fact that the The hub of the rotor of the electric generator is assembled to the cylinder of a servomotor for adjusting the turbine, this cylinder resting by means of a sleeve on the thrust bearing.
The appended drawing shows schematically and by way of example two embodiments of the generator set, object of the invention.
The generator set shown comprises an alternator 1 of the umbrella type and a turbine 2 of the Kaplan type. The rotating part of the group is guided by two bearings 3 and 4 and supported by a stop 5.
In the example of FIG. 1, the guide bearing 4 of the upper machine, that is to say of the electric generator, bears directly on the shaft. This guide bearing and the stop 5 are carried by a common support 6, integral with the cover 7 which rests on the distribution cover of the turbine. The rotating sleeve 8 rests on the rotating part of the stop 5 and is integral with the cylinder 9 of the Kaplan servomotor, and this part is intended to be coupled, at its inner part, to the shaft 10 of the turbine, by a circular flange 11 and on its part outside the hub 12 of the alternator, by flange 13.
The hub 12 of the alternator has a shape suitable for its coupling to the flange 13 and with the aim of bringing the center of gravity of the rotor of the alternator as close as possible to the action plane of the guide bearing 4, this hub 12 largely surrounds the thrust bearing 5, which leads to a significant saving in the overall height of the group. The cylinder 9 of the booster carries at its outer periphery the ba ged collector 14 for supplying the excitation current to the rotor of the alternator.
The support 6 of the thrust bearing also serves as a support for the lifting cylinders 1.5 attaching the rotor of the alternator by its hub 12.
The alternator 1 is thus freed from any significant load. It has neither lower cross lon nor jack support consoles, and its upper cross member 16 only serves as a closing floor and support for the Kaplan adjustment head, not shown in the figure. The spider 16 also carries the brake cylinders 17 attacking the rotor from top to bottom.
In the variant of FIG. 2, the upper guide bearing 4 'bears on the rotating part of this stop.
The rotating sleeve 8 resting on the rotating part of the stop 5 is integral, as in the example of fig. 1, with the cylinder 9 of the Kaplan servo motor and is intended to be coupled, by the flange 11, to the shaft 10 of the turbine, and by the flange 13, to the hub 12 of the alternator;
this remains above the thrust bearing 5, the reduction of the group in height which, in the case of fig. 1, was due to the hub 12 surrounding the thrust bearing 5, is here achieved because it is on the rotating part of this stop 5 that the guide bearing 4 'rests.
