- a ship building site can last several months, and thus the lock gate will remain stationary in the position of the figure 12 all the time that will last the construction of the ship.
- the figure 12 also shows a lower cavity 8, bounded downwards by the race 2, upwards by the lower face 10 of the door 1, and on the sides by the lower portions 61,64 of the first and second spans of FIG. lock masonry. It is generally in this cavity that detritus and / or mud accumulate, which are then deposited on the raceway 2.
- the invention proposes the use of the inflatable seal 6, which can be inflated or deflated, and whose operation will be described below.
- the figure 13 is a view similar to figures 5 and 9 , the door being pressed this time on its second main face 12 by pressure.
- the inflatable seal 6 is in the state of rest, that is to say not inflated; on the other hand in the case illustrated on the figure 13 (and also on figures 14 and 16b ) the inflatable seal 6 is in the inflated position.

- the figure 14 is a view similar to the figure 12 , in which the inflatable seal is inflated, identical configuration to that just described for the figure 13 .
- the internal space 16 of the door 1, including the access cavity 3 located in the lower part, remain filled with water, but without communication with the first space 81.
- the figure 15 is a schematic sectional view, parallel to the YZ plane, along line XV of the figure 13 , where it can be seen that the inflatable seal 6 extends continuously along the first masonry span by traversing a 'U' shape, and comprising a lower portion 6a, a front vertical portion 6b and a portion vertical rear 6c, so as to be pressed against the 'U' formed by the first masonry 61,32,63 range.
- the inflatable seal 6 is made in one piece, the lower part 6a being connected in continuity with the front vertical portion 6b respectively and with the rear vertical portion 6c.
- the first sealing device 31, 32, 33 is also in the form of a 'U' open top and of the same shape as the 'U' formed by the first masonry span 61, 32, 63 so as to be able to press one against the other in a continuous manner on any the length of this shape in 'U', thus providing the desired seal.
- the section also shows a portion 110 of the edge of the first main face, visible because the rear vertical portion 32 is projecting relative to the other portions of the first sealing device, and is somewhat offset to the X positive.

- the profile of the inflatable seal 6 comprises a base 94 parallel to the first main face 11, first and second lateral flanges 92, 93, extending perpendicularly to said base 94, and a flexible membrane portion 90, 91 which moves between a retracted position 90 if the inflatable seal 6 is deflated and a protruding position 91 if the inflatable seal 6 is inflated.
- the flexible membrane portion In the deflated state, the flexible membrane portion does not exceed the thickness defined by the lower portion of the first sealing device 31, whereas in the inflated state, the flexible membrane portion protrudes and bears against the lower portion 61 of the first masonry span, thus canceling the clearance 23 created by the fact that the door is pressed against the second masonry span.
- the sectional profile of the inflatable seal 6 which has just been described extends continuously over the entire length of said inflatable seal 6, thus defining an interior space 95 which extends all along the 'U' formed by the seal 6. Therefore, it is sufficient to connect this space 95 to an inflation device (not shown) for example at the upper end of the rear vertical portion 6c of the inflatable seal 6, so that it is it is possible to simultaneously inflate the assembly of the inflatable seal 6, or conversely to deflate it simultaneously.
- the inflatable seal 6 is equipped with a pressure sensor 96 which makes it possible to control the pressure prevailing in the inner space 95 of the inflatable seal 6, in particular so as to detect a potential leak.
- a second inflatable seal similar to the first, can be mounted on the second main face 12 of the door, with a geometry symmetrical with respect to the YZ plane.
- This second inflatable seal, mounted on the second main face 12, may be a complementary solution of the auxiliary sealing device 37,38,39 or even replace this same auxiliary sealing device 37,38,39 to avoid maneuvers to set up the latter.

Des portes d'écluses sont utilisées en rivière pour séparer deux biefs situés à des niveaux différents, et dans ce cas les portes d'écluses sont utilisées par paire, une paire de portes encadrant un sas dont le niveau d'eau est variable et maitrisé.Lock gates are used in the river to separate two reaches at different levels, and in this case the lock gates are used in pairs, a pair of doors flanking an airlock whose water level is variable and controlled .
On utilise également de telles portes pour fermer l'accès à un bassin portuaire, soit pour maintenir le bassin à niveau constant, indépendamment des marées, soit pour utiliser un tel bassin comme chantier de construction navale, le bassin étant alors asséché et isolé de la mer.Such gates are also used to close access to a harbor basin, either to maintain the pool at a constant level, regardless of the tides, or to use such a basin as a shipyard, the basin being then drained and isolated from the sea. sea.
Il est d'usage d'utiliser des portes d'écluses à vantaux pour des portes d'écluses de dimensions petites ou moyennes, et il est connu dans l'art d'utiliser, pour des portes de grandes dimensions, des portes d'écluses roulantes.It is customary to use leaf lock gates for small or medium sized lock gates, and it is known in the art to use gates for large doors. rolling locks.
De telles portes d'écluse roulantes connues dans l'art comprennent généralement :
- une structure rigide, ayant des première et deuxième faces principales parallèles, une face inférieure, une face d'extrémité avant, une face d'extrémité arrière, et une face supérieure.
- a rigid structure, having first and second parallel main faces, a lower face, a front end face, a rear end face, and an upper face.
Dans les portes d'écluse roulantes connues dans l'art, lorsque la porte d'écluse reste longtemps en position fermée, il arrive que le chemin de roulement sur lequel se déplace la porte d'écluse roulante se remplisse de vase et/ou de détritus, notamment au gré des marées.In rolling lock gates known in the art, when the lock gate remains in a closed position for a long time, it sometimes happens that the raceway on which the rolling lock gate is moving is filled with mud and / or detritus, especially with the tides.
La présente invention a notamment pour but de perfectionner les portes d'écluse roulantes.The present invention is intended in particular to improve the rolling lock doors.
A cet effet, selon l'invention, une porte d'écluse roulante du genre en question est caractérisée en ce que ladite porte d'écluse comprend au moins un joint d'étanchéité gonflable solidaire de la porte et situé au moins le long d'un bord inférieur d'une des faces principales.For this purpose, according to the invention, a lock gate rolling wheel of the kind in question is characterized in that said lock gate comprises at least one inflatable seal integral with the door and located at least along a lower edge of one of the main faces.
Grâce à ces dispositions, le chemin de roulement situé sous la porte d'écluse roulante peut être isolé lors des périodes longues de fermeture de la porte d'écluse roulante et on évite ainsi que le chemin de roulement ne se remplisse de vase et/ou de détritus, notamment au gré des marées.Thanks to these provisions, the raceway located under the rolling lock gate can be isolated during long periods of closure of the rolling lock gate and thus prevents the raceway from filling with sludge and / or of detritus, especially with the tides.
Dans divers modes de réalisation de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivante :
- le joint est fixé sur la première face principale de la porte ;

En outre, la porte d'écluse roulante 1 selon l'invention peut aussi contenir un joint d'étanchéité gonflable 6, ayant lui aussi une forme générale de 'U' ouvert vers le haut, situé sur les bords de la première face principale 11. Le joint d'étanchéité gonflable 6 est adjacent au premier dispositif d'étanchéité 31,32,33 sur toute la longueur de celui-ci, et ses dimensions selon les axes Y et Z sont légèrement inférieures aux dimensions du premier dispositif d'étanchéité 31,32,33 selon les axes Y et Z, de sorte que le 'U' que parcourt le joint d'étanchéité gonflable s'inscrit juste à l'intérieur du 'U' que parcourt le premier dispositif d'étanchéité 31,32,33.In addition, the rolling
Le joint d'étanchéité gonflable 6 comporte une portion rigide fixé à la première face principale, et une portion flexible, réalisée par exemple à base de caoutchouc ou de plastique souple.The

De façon similaire, les portions horizontale et verticale 34,36 du deuxième dispositif d'étanchéité sont séparées des portions inférieure et verticale 64,66 de la deuxième portée de la maçonnerie d'écluse par un deuxième jeu fonctionnel, qui est sensiblement identique au premier jeu fonctionnel en l'absence d'efforts exercés sur la porte 1 selon la direction X.Similarly, the horizontal and

En effet, la portion horizontale 31 avant du premier dispositif d'étanchéité est plaquée contre la portion inférieure 61 de la première portée de la maçonnerie d'écluse. De même, les portions verticales avant et arrière 33, 32 du premier dispositif d'étanchéité sont respectivement plaquées contre les portions verticales avant et arrière 63,62 de la première portée de la maçonnerie d'écluse. Il est à noter que la première face principale 11 présente une surface continue à l'intérieur de la surface délimitée par le 'U' formé par le premier dispositif d'étanchéité, donc l'eau ne peut pas passer à travers la première face principale 11.Indeed, the
Du coté opposé, à savoir du côté de la seconde face principale 12, il existe un jeu fonctionnel 26 plus important, le deuxième dispositif d'étanchéité 34,35,36 étant éloigné de la deuxième portée de la maçonnerie 64,65,66.On the opposite side, namely on the side of the second
La
Du coté de la seconde face principale 12, le deuxième dispositif d'étanchéité 34,35,36 étant éloigné de la deuxième portée de la maçonnerie 64,65,66, et le jeu fonctionnel 26 laisse passer l'eau en provenance du deuxième espace 82, cette eau remplissant l'espace intérieur 16 de la porte, y compris la cavité d'accès 3 en partie inférieure, et aussi le chemin de roulement 2. Le niveau d'eau à l'intérieur de la porte est au même niveau que l'eau dans le deuxième espace 82.On the side of the second

Ainsi le logement de retrait 7, l'espace interne 16 de la porte 1 et la cavité d'accès 3 sont isolés de manière étanche des deux étendues d'eau 81,82. On peut alors procéder à l'assèchement de cette zone. Pour ce faire, un dispositif de pompage 19 (non détaillé car connu dans l'état de la technique) est utilisé : on prélève l'eau se situant dans le logement de retrait 7 jusqu'à assèchement de celui-ci, ainsi que de la cavité d'accès 3 qui est en communication fluide avec ledit logement de retrait 7.Thus the recess housing 7, the
Après que la cavité d'accès 3 a été vidée et asséchée, il est possible pour un humain de descendre dans ladite cavité d'accès 3, empruntant un passage 17 prévu à cet effet, situé dans l'espace interne 16 de la porte 1, et qui s'étend depuis la face supérieure 15 jusqu'à la cavité d'accès 3, et comportant par exemple un ou plusieurs escaliers 17. La cavité d'accès 3 étant ouverte vers le bas, le ou les intervenants humains peuvent inspecter le chemin de roulement 2, le ou les rails 41, qui le reste du temps sont inaccessibles car immergés.After the

Grâce à cette disposition, l'élément inférieur 37 peut être facilement manoeuvré entre la position de retrait et la position active, et inversement, et on évite une opération de manutention difficile pour amener et descendre au fond de l'écluse ledit élément inférieur 37.Thanks to this arrangement, the

Dans cette configuration, la porte est décalée de sa position neutre dans la direction des X négatifs et sa deuxième face principale 12 bute sur la deuxième portée de la maçonnerie 64,65,66. Ceci a pour conséquence d'isoler de façon étanche le deuxième espace 82 par rapport à l'espace interne 16 de la porte d'écluse, au chemin de roulement 2 et au premier espace 81.In this configuration, the door is shifted from its neutral position in the direction of the negative X and its second
En effet, la portion horizontale 34 du deuxième dispositif d'étanchéité est plaquée contre la portion inférieure 64 de la deuxième portée de la maçonnerie d'écluse. De même, les portions verticales avant et arrière 36, 35 du deuxième dispositif d'étanchéité sont respectivement plaquées contre les portions verticales avant et arrière 66,65 de la deuxième portée de la maçonnerie d'écluse. Il est à noter que, comme la première face principale 11, la deuxième face principale 12 présente une surface continue à l'intérieur de la surface délimitée par le 'U' formé par le deuxième dispositif d'étanchéité, donc l'eau ne peut pas passer à travers la deuxième face principale 12.Indeed, the
Comme cela a été indiqué au début de la description, le niveau de liquide dans l'espace 82 peut être piloté par des moyens hydrauliques. En particulier, le niveau peut être abaissé jusqu'à ce que ce deuxième espace 82 soit complètement vidé. En effet, si l'on veut construire ou réparer un navire à sec, on procède à l'assèchement du deuxième espace 82 (comme cela est illustré sur la
Du coté opposé, à savoir du côté du premier espace 81 et de la première face principale 11, il existe un jeu fonctionnel 23 important, le premier dispositif d'étanchéité 31,32,33 étant éloigné de la première portée de la maçonnerie 61,62,63, l'eau du premier espace 81 peut donc pénétrer par ce jeu dans l'espace intérieur 16 de la porte.On the opposite side, namely on the side of the

Dans ces conditions, si aucune précaution n'est prise, compte-tenu du jeu 23 qui laisse rentrer et sortir l'eau du côté de la première face principale 11 et du premier espace 81 au gré des marées, de la vase et/ou des détritus s'accumulent petit à petit au niveau du chemin de roulement 2. Ceci devient problématique le jour où l'on veut à nouveau manoeuvrer la porte d'écluse 1 pour la déplacer vers sa position ouverte : la vase et les détritus présents sur le chemin de roulement 2 empêche la roue 42 de rouler correctement sur le rail 41.Under these conditions, if no precaution is taken, taking into account the
Pour pallier cet inconvénient, l'invention propose l'utilisation du joint d'étanchéité gonflable 6, qui peut être gonflé ou dégonflé, et dont le fonctionnement va être décrit ci-après.To overcome this drawback, the invention proposes the use of the
La
Dans cette position, le joint d'étanchéité gonflable 6 s'étend en direction opposé à la première face principale 11, et sur toute la longueur du joint d'étanchéité gonflable 6, il vient porter sur la première portée de maçonnerie 61,62,63.In this position, the
Ainsi il obture le jeu 23 entre la première face principale 11 et la première portée de maçonnerie 61,62,63, si bien que l'espace interne 16 de la porte, la cavité d'accès 3 et le chemin de roulement 2 ne sont plus en communication directe avec le premier espace 81. De même, la cavité inférieure 8 ainsi que le logement de retrait 7 sont isolés du premier espace et on évite ainsi que des détritus ou de la vase viennent se déposer sur le chemin de roulement 2.Thus it closes the

Le premier dispositif d'étanchéité 31,32,33, se présente aussi sous forme de 'U' ouvert le haut et de même forme que le 'U' formé par la première portée de maçonnerie 61,32,63 de manière à pouvoir se plaquer l'un contre l'autre de manière continue sur toute la longueur de cette forme en 'U', procurant ainsi l'étanchéité recherchée.The

Le profil du joint d'étanchéité gonflable 6 comprend une base 94 parallèle à la première face principale 11, des première et deuxième joues latérales 92,93, s'étendant perpendiculairement à la dite base 94, et une partie de membrane souple 90,91 qui se déplace entre une position de retrait 90 si le joint d'étanchéité gonflable 6 est dégonflé et une position en saillie 91 si le joint d'étanchéité gonflable 6 est gonflé.The profile of the
Dans l'état dégonflé, la partie de membrane souple ne dépasse pas de l'épaisseur défini par la portion inférieure du premier dispositif d'étanchéité 31, alors que dans l'état gonflé, la partie de membrane souple fait saillie et vient porter contre la partie inférieur 61 de la première portée de maçonnerie, annulant ainsi le jeu 23 créé du fait que la porte est plaquée contre la deuxième portée de maçonnerie.In the deflated state, the flexible membrane portion does not exceed the thickness defined by the lower portion of the
Le profil en section du joint d'étanchéité gonflable 6 qui vient d'être décrit s'étend continument sur la totalité de la longueur du dit joint d'étanchéité gonflable 6, définissant ainsi un espace intérieur 95 qui s'étend tout le long du 'U' formé par le joint d'étanchéité gonflable 6. Par conséquent, il suffit de connecter cet espace 95 à un dispositif de gonflage (non représenté) par exemple au niveau de l'extrémité supérieure de la portion verticale arrière 6c du joint d'étanchéité gonflable 6, pour qu'il soit possible de gonfler simultanément l'ensemble du joint d'étanchéité gonflable 6, ou inversement de la dégonfler simultanément.The sectional profile of the
Par ailleurs, selon l'invention, le joint d'étanchéité gonflable 6 est équipé d'un capteur de pression 96 qui permet de contrôler la pression régnant dans l'espace intérieur 95 du joint d'étanchéité gonflable 6, de manière en particulier à détecter une fuite potentielle.Furthermore, according to the invention, the
Par ailleurs, selon l'invention, un deuxième joint d'étanchéité gonflable, analogue au premier, peut être monté sur la deuxième face principale 12 de la porte, avec une géométrie symétrique par rapport au plan YZ. Ce deuxième joint d'étanchéité gonflable, monté sur la deuxième face principale 12, peut être une solution complémentaire du dispositif d'étanchéité auxiliaire 37,38,39 ou même remplacer ce même dispositif d'étanchéité auxiliaire 37,38,39 pour éviter les manoeuvres de mise en place de ce dernier.Furthermore, according to the invention, a second inflatable seal, similar to the first, can be mounted on the second
