Description

La présente invention a trait à un outil de nettoyage de surfaces surplombantes et en particulier de plafonds et de voûtes, surfaces qui peuvent être plates ou courbes.The present invention relates to a tool for cleaning overhanging surfaces and in particular ceilings and vaults, surfaces which can be flat or curved.

Un problème important posé lors du nettoyage industriel de ces surfaces consiste en ce que les liquides de nettoiement et de rinçage qui y sont projetés retombent en pluie ou en ruisselant le long de parois latérales, ce qui est indésirable dans nombre de cas, notamment pour le nettoiement des couloirs et quais de métropolitain où une telle humidité produirait des dégâts et ne pourrait s'évaporer.A major problem posed during the industrial cleaning of these surfaces consists in that the cleaning and rinsing liquids which are sprayed therein fall in rain or by dripping along side walls, which is undesirable in many cases, in particular for the cleaning of metro corridors and platforms where such humidity would cause damage and could not evaporate.

Le brevet français no2 579 535 présente ainsi un système de nettoiement comprenant en particulier des buses d'arrosage a l'extrémité d'un bras mobile et déformable fixé à un véhicule ; les rampes de buses d'arrosage sont extensibles dans le sens transversal, ce qui leur permet, selon la courbure de la voûte, de nettoyer la plus grande largeur possible. Toutefois, ce système ne possède aucun dispositif de récupération des eaux usées et ne résout donc pas le problème évoqué ci­dessus.French Patent No. 2,579,535 thus has a cleaning system comprising in particular spray nozzles has the end of a mobile and deformable arm fixed to a vehicle; the spray nozzle ramps are extendable in the transverse direction, which allows them, depending on the curvature of the vault, to clean as wide as possible. However, this system does not have any wastewater recovery device and therefore does not solve the problem mentioned above.

Un objet essentiel de l'invention est donc de fournir un outil de nettoyage qui permette de récupérer les eaux usées. On y parvient en entourant les buses de projection de liquide d'un bac ouvert vers la surface à nettoyer et muni d'une bordure qui crée une étanchéité en s'appuyant sur cette surface.An essential object of the invention is therefore to provide a cleaning tool which makes it possible to recover the waste water. This is achieved by surrounding the liquid spray nozzles with a tank open to the surface to be cleaned and provided with a border which creates a seal by pressing on this surface.

Il est cependant nécessaire que le bac, qui doit être de largeur assez importante pour obtenir des cadences de nettoyage acceptables, soit déformable transversalement pour s'adapter à la courbure des voûtes. Le bac a donc une forme d'ensemble variable et s'appuie sur le bras du véhicule par une succession d'appuis élastiques, d'autres appuis élastiques pouvant par ailleurs relier diverses parties rigides du bac entre elles.It is however necessary that the tank, which must be wide enough to obtain acceptable cleaning rates, or deformable transversely to adapt to the curvature of the vaults. The container therefore has a variable overall shape and is supported on the arm of the vehicle by a succession of elastic supports, other elastic supports being able moreover to connect various rigid parts of the container to one another.

Un autre objet de l'invention est d'incorporer des moyens qui permettent de commander la courbure du bac avant que celui-ci n'atteigne la surface à nettoyer, de façon à ne devoir appuyer sur cette surface qu'avec une pression modérée et uniforme sur toute la largeur du bac. Un objet supplémentaire de l'invention consiste à incorporer des moyens de lavage appropriés et efficaces dans le bac.Another object of the invention is to incorporate means which make it possible to control the curvature of the container before it reaches the surface to be cleaned, so as to have to press on this surface only with moderate pressure and uniform over the entire width of the tank. A further object of the invention consists in incorporating suitable and effective washing means in the tank.

L'outil de nettoyage selon l'invention comprend donc, dans sa forme la plus générale, un bac ouvert vers la surface à nettoyer et muni d'une bordure souple destinée à s'appuyer sur la surface en réalisant une liaison étanche, le bac étant disposé à une extrémité d'un bras mobile dont l'autre extrémité est liée à un véhicule, l'intérieur du bac étant muni de buses de projection de liquide de nettoyage vers la surface et d'un dispositif de récupération de liquide de nettoyage usé, le bac étant par ailleurs déformable pour s'adapter à la courbure de la surface et relié au bras par des raccordements incluant des appuis élastiques.The cleaning tool according to the invention therefore comprises, in its most general form, a container open towards the surface to be cleaned and provided with a flexible border intended to rest on the surface by forming a sealed connection, the container being disposed at one end of a movable arm the other end of which is linked to a vehicle, the inside of the tank being provided with nozzles for spraying cleaning liquid towards the surface and with a device for recovering cleaning liquid worn, the tank being also deformable to adapt to the curvature of the surface and connected to the arm by connections including elastic supports.

Dans sa réalisation préférée, le bac est composé de parties disposées en chaîne transversale et reliées entre elles par des articulations. Ces parties peuvent ainsi être au nombre de trois, les deux parties extrêmes étant reliées au bras par des appuis élastiques et la partie médiane étant soutenue par les parties extrêmes à l'aide de raccordements élastiques. Notamment dans cette réalisation, les appuis élastiques peuvent consister en des ressorts d'extension oblique et déplaçables horizontalement ou obliquement par rapport au bras mobile pour pouvoir ajuster la courbure du bac.In its preferred embodiment, the container is made up of parts arranged in a transverse chain and connected together by articulations. These parts can thus be three in number, the two end parts being connected to the arm by elastic supports and the middle part being supported by the end parts by means of elastic connections. In particular in this embodiment, the elastic supports may consist of oblique extension springs which can be moved horizontally or obliquely relative to the movable arm in order to be able to adjust the curvature of the tank.

Les buses de projection de liquide pourront être complétées par des brosses rotatives.The liquid spray nozzles can be completed with rotating brushes.

L'invention va maintenant être décrite dans sa réalisation préférée à l'aide des cinq figures suivantes annexées à titre illustratif et non limitatif :

  • la figure 1 est une vue de face de l'invention ;
  • - la figure 2 est une vue de dessus de l'invention ;
  • - la figure 3 est une vue d'un détail de la figure 1 ;
  • - la figure 4 est une vue de côté d'un détail de la figure 3 ; et
  • - la figure 5 représente un élément constitutif de l'invention vu de côté.
The invention will now be described in its preferred embodiment with the aid of the following five figures annexed by way of illustration and not limitation:
  • Figure 1 is a front view of the invention;
  • - Figure 2 is a top view of the invention;
  • - Figure 3 is a view of a detail of Figure 1;
  • - Figure 4 is a side view of a detail of Figure 3; and
  • - Figure 5 shows a component of the invention seen from the side.

Les figures montrent que l'outil de nettoyage est monté au-dessus d'un véhicule 1 qui peut être selon le cas conduit ou automatique et sur la surface supérieure duquel s'élève un bras mobile 2. Le bras mobile 2 est déformable et possède un degré de liberté de translation verticale 3, un degré de liberté de rotation dans le plan transversal (roulis) 4 et un degré de liberté de rotation dans le plan longitudinal 5 (tangage), les mots "longitudinal" et "transversal" étant pris par rapport au sens de marche 6 du véhicule 1. Le bras mobile 2 est par ailleurs relié au véhicule 1 par une liaison à rotule et vérins 8 qui lui permet d'être orienté. La surface à nettoyer 7 est ici une voute légèrement concave, mais l'invention peut egalement s'appliquer à des plafonds plats, à des surfaces supérieures également convexes ainsi qu'à des murs collatéraux obliques de voûtes, et d'une façon générale à toute surface surplombante.The figures show that the cleaning tool is mounted above a vehicle 1 which can be driven or automatic depending on the case and on the upper surface of which rises a movable arm 2. The movable arm 2 is deformable and has a degree of freedom of vertical translation 3, a degree of freedom of rotation in the transverse plane (roll) 4 and a degree of freedom of rotation in the longitudinal plane 5 (pitch), the words "longitudinal" and "transverse" being taken relative to the direction of travel 6 of the vehicle 1. The movable arm 2 is also connected to the vehicle 1 by a ball joint and jacks 8 which allows it to be oriented. The surface to be cleaned 7 is here a slightly concave arch, but the invention can also apply to flat ceilings, to upper surfaces that are also convex as well as to oblique collateral walls of arches, and generally to any overhanging surface.

L'outil de nettoyage 10 comprend tout d'abord un bac 11 composé de trois parties disposées en chaîne :une partie centrale 12 et deux parties extrêmes 13 situées transversalement par rapport à la partie centrale 12. Les parties centrale 12 et extrêmes 13 délimitent un volume commun 14 ouvert vers le haut. Chacune des parties 12 et 13 est munie d'une bordure supérieure le long de son contour, qui est suffisamment souple pour pouvoir s'appliquer sur la voûte 7 en suivant la courbure de celle-ci et en maintenant par conséquent l'étanchéité. Plus précisément, on peut préconiser, pour chacune des parties 12 et 13, une bordure double constituée d'une bordure de poils de brosse très denses 15 et une bordure en bande racleuse souple 16 telle que du Néoprène parallèle et extérieure à la précédente. Les bordures 17 avant et arrière présentent des zones de recouvrement 18 à la jonction des parties 12 et 13 du bac. Les parties extrêmes 13 possèdent également une bordure latérale double 17 de même nature. Cette disposition est utile pour maintenir l'étanchéité du bac 11 quand il s'appuie sur des surfaces à reliefs, comme les surfaces de métropolitain recouvertes de carreaux dont les chanfreins sont importants : les bandes racleuses 16 ont une assez forte rigidité de torsion, si bien qu'elles ne peuvent pénétrer entre les chanfreins de carreaux jointifs. Les poils de brosse ont en revanche cette faculté.The cleaning tool 10 firstly comprises a tank 11 composed of three parts arranged in a chain: a central part 12 and two end parts 13 located transversely to the central part 12. The central 12 and end parts 13 define a common volume 14 open upwards. Each of the parts 12 and 13 is provided with an upper border along its contour, which is flexible enough to be able to be applied to the arch 7 by following the curvature thereof and consequently maintaining the seal. More precisely, it is possible to recommend, for each of the parts 12 and 13, a double border consisting of a border of very dense brush bristles 15 and a border in flexible scraper strip 16 such as neoprene parallel and external to the previous one. The front and rear edges 17 have overlap zones 18 at the junction of the parts 12 and 13 of the tank. The end portions 13 also have a double side border 17 of the same kind. This arrangement is useful for maintaining the tightness of the tank 11 when it rests on relief surfaces, such as metropolitan surfaces covered with tiles whose chamfers are large: the scraper strips 16 have a fairly high torsional rigidity, if although they cannot penetrate between the chamfers of adjoining tiles. Brush hairs, on the other hand, have this ability.

Alors que la souplesse des bordures 17 permet de s'adapter dans une certaine mesure aux variations de courbure de la voûte 7, l'outil de nettoyage 10 doit pouvoir s'adapter à des surfaces à nettoyer de formes beaucoup plus variées. De plus, les bordures doivent être appliquées avec une pression relativement faible sur la surface 7, ce que le degré de liberté vertical 3 du véhicule est impuissant à assurer à lui seul.While the flexibility of the edges 17 makes it possible to adapt to a certain extent to the variations in curvature of the arch 7, the cleaning tool 10 must be able to adapt to surfaces to be cleaned of shapes much more varied. In addition, the edges must be applied with a relatively low pressure on the surface 7, which the vertical degree of freedom 3 of the vehicle is powerless to provide alone.

La première difficulté est résolue par un montage non rigide des différentes parties 12 et 13 du bac 11 entre elles ; la seconde est résolue par un montage élastique du bac 11 sur le bras mobile 2.The first difficulty is solved by a non-rigid mounting of the different parts 12 and 13 of the tank 11 between them; the second is resolved by an elastic mounting of the tank 11 on the movable arm 2.

A cet effet, chacune des parties extrêmes 13 est reliée à la partie centrale 12 au moyen d'une articulation 20 d'axe longitudinal, ainsi que par des soufflets 21 au-dessous des bordures 17 pour maintenir l'étanchéité.To this end, each of the end parts 13 is connected to the central part 12 by means of an articulation 20 with a longitudinal axis, as well as by bellows 21 below the edges 17 to maintain the seal.

Une liaison élastique en rotation entre la partie centrale 12 et les parties extrêmes 13 est apportée par des ressorts à lame 22 dont une extrémité est fixée au fond de la partie centrale 12 et dont l'autre extrémité s'appuie, par l'intermédiaire d'une vis de réglage 23, sur le fond des parties extrêmes 13.An elastic connection in rotation between the central part 12 and the end parts 13 is provided by leaf springs 22, one end of which is fixed to the bottom of the central part 12 and the other end of which is supported by means of 'an adjustment screw 23, on the bottom of the end portions 13.

Par ailleurs (figures 3 et 4), les parties extrêmes 13 sont reliées au bras mobile 2 par un mécanisme comprenant, pour chacun d'entre eux, un vérin électrique 52 dont le corps 53 est articulé au bras mobile 2 par un pivot 54 et dont la tige 55 entraîne un coude 56 dont le grand côté 57 coulisse avec un jeu suffisant dans un évidement 58 du grand côté d'une équerre 59. L'équerre 59 est reliée au bras mobile 2 par une articulation 60 ; son petit côté est muni d'un point d'attache articulé 61 pour une extrémité d'un ressort de traction 62, dont l'autre extrémité est fixée à un point d'attache articulé 63 du petit côté du coude 56.Furthermore (Figures 3 and 4), the end parts 13 are connected to the mobile arm 2 by a mechanism comprising, for each of them, an electric actuator 52 whose body 53 is articulated to the mobile arm 2 by a pivot 54 and whose rod 55 drives an elbow 56 whose long side 57 slides with sufficient clearance in a recess 58 on the long side of a bracket 59. The bracket 59 is connected to the movable arm 2 by a hinge 60; its short side is provided with an articulated attachment point 61 for one end of a tension spring 62, the other end of which is fixed to an articulated attachment point 63 on the short side of the elbow 56.

L'équerre 59 comprend, sur la face de son grand côté opposée au vérin électrique 52, deux montants recourbés 64 séparés par une rainure 65 et enfermant un chemin de roulement 66. Une patte triangulaire 67 dont la base est fixée au fond de la partie extrême 13 pénètre à travers la rainure 65, et sa pointe est munie d'un rouleau 68 qui circule dans le chemin de roulement 66.The bracket 59 comprises, on the face of its large side opposite to the electric actuator 52, two curved uprights 64 separated by a groove 65 and enclosing a raceway 66. A triangular tab 67 whose base is fixed to the bottom of the end portion 13 penetrates through the groove 65, and its point is provided with a roller 68 which circulates in the raceway 66.

L'extension de la tige 55 du vérin électrique 53 entraîne une tension supplémentaire du ressort 62, et donc un pivotement de l'équerre 59 qui soulève la partie extrême 13, modifiant les angles entre les différentes parties 12 et 13 du bac 11 et donc son rayon de courbure. Pour chaque utilisation, les vis 23 qui agissent en coopération avec les ressorts à lame 22 peuvent évidemment être réglées.The extension of the rod 55 of the electric jack 53 causes additional tension of the spring 62, and therefore a pivoting of the bracket 59 which lifts the end part 13, modifying the angles between the different parts 12 and 13 of the tank 11 and therefore its radius of curvature. For each use, the screws 23 which act in cooperation with the leaf springs 22 can obviously be adjusted.

La position d'ensemble du bac 11 est maintenue au moyen d'un mât vertical 27 qui coulisse dans le bras mobile 2 et dont une extrémité est constituée par une chape 50 articulée à l'avant et à l'arrière de la partie centrale 12, à deux bouts d'arbre 51 dépassant de celle-ci.The overall position of the tank 11 is maintained by means of a vertical mast 27 which slides in the movable arm 2 and one end of which is constituted by a yoke 50 articulated at the front and at the rear of the central part 12 , at two ends of the shaft 51 protruding therefrom.

Le rayon de courbure du bac 11 est communiqué au véhicule par un palpeur 69 sur le bras mobile 2 et dont le doigt 70 vient au contact d'une surface biseautée 71 du mât vertical 27.The radius of curvature of the tank 11 is communicated to the vehicle by a feeler 69 on the movable arm 2 and whose finger 70 comes into contact with a beveled surface 71 of the vertical mast 27.

On se reporte maintenant davantage à la figure 2 pour examiner les différents composants utilisés pour le nettoyage et leur disposition dans le bac 11.We now refer more to FIG. 2 to examine the various components used for cleaning and their arrangement in the tank 11.

On remarque tout d'abord que le volume 14 est pour l'essentiel occupé par des brosses 30 rotatives, de forme cylindrique et montées chacune sur un tambour 31 ou 31′. Une brosse 30 s'étend dans chaque partie 12 ou 13 du bac 11 et son sens de rotation est transversal. L'entraînement est effectué par l'un ou l'autre de deux moteurs électriques 32 disposés dans les tambours 31 des brosses 30 situées dans les parties extrêmes 13.First of all, it is noted that the volume 14 is essentially occupied by rotary brushes 30, of cylindrical shape and each mounted on a drum 31 or 31 ′. A brush 30 extends in each part 12 or 13 of the tank 11 and its direction of rotation is transverse. The drive is carried out by one or the other of two electric motors 32 arranged in the drums 31 of the brushes 30 located in the parts extremes 13.

Les moteurs 32 s'appuient sur les bords latéraux 33 des parties extrêmes 13 ; leurs arbres sont terminés chacun par un accouplement sphérique 34 formé comme son nom l'indique d'une portion de sphère. Le tambour 31′ de la brosse 30 située dans la partie centrale 12 est muni de flasques extrêmes évidés de façon à pouvoir y introduire les deux accouplements sphériques 34, soutenant ainsi le tambour 31′ qui est par ailleurs relié en rotation à l'un des accouplements sphériques 34 par un clavetage 35.The motors 32 are supported on the lateral edges 33 of the end portions 13; their shafts are each terminated by a spherical coupling 34 formed as its name indicates a portion of a sphere. The drum 31 ′ of the brush 30 located in the central part 12 is provided with end flanges hollowed out so as to be able to introduce there the two spherical couplings 34, thus supporting the drum 31 ′ which is also connected in rotation to one of the spherical couplings 34 by keying 35.

Les tambours 31 des brosses 30 situées dans les parties extrêmes 13 sont par contre reliés rigidement à l'accouplement sphérique 34 du moteur 32 qu'elles entourent. Pour permettre de réaliser ces différentes liaisons, les tambours 31 et 31′ de brosses 30 adjacentes présentent chacun une saillie 36 et un évidement 37 complémentaire - leur contour étant en forme d'un pas d'hélice - et qui permettent de réaliser un emboîtage des tambours 31 et 31′ avec un léger jeu qui est fonction des déformations de courbure du bac 11 que l'on s'autorise.The drums 31 of the brushes 30 situated in the end parts 13 are on the other hand rigidly connected to the spherical coupling 34 of the motor 32 which they surround. To allow these different connections to be made, the adjacent drums 31 and 31 of brushes 30 each have a projection 36 and a complementary recess 37 - their outline being in the form of a helix pitch - and which make it possible to nest the drums 31 and 31 ′ with a slight clearance which is a function of the deformations of curvature of the tank 11 which are authorized.

Les tambours 31 des brosses 30 situées dans les parties extrêmes 13 sont perforés de façon que le liquide détergent issu de deux rangées 38 de buses de projection de liquide de nettoiement puisse traverser les tambours 31. Les rangées 38 de buses sont ici au nombre de deux pour chaque partie extrême 13 et sont situées entre le moteur 32 et le tambour 31, à l'avant et à l'arrière du moteur 32. Leurs buses de projection 39 sont orientées à la fois vers le haut et vers l'intérieur dans le sens transversal de façon à effectuer un arrosage uniforme de la voûte 7, y compris à l'emplacement de la partie centrale 12. Les rangées 38 s'étendent sur toute la longueur des brosses 30 et sont alimentées par des tuyaux 40 partiellement représentés et qui sortent des bords latéraux 33 des parties extrêmes 13 pour se raccorder au véhicule 1 en étant attachés de manière lâche au bras mobile 2.The drums 31 of the brushes 30 located in the end portions 13 are perforated so that the detergent liquid coming from two rows 38 of nozzles for spraying cleaning liquid can pass through the drums 31. The rows 38 of nozzles are here two in number for each end portion 13 and are located between the motor 32 and the drum 31, at the front and at the rear of the motor 32. Their projection nozzles 39 are oriented both upwards and inwards in the transverse direction so as to effect a uniform watering of the arch 7, including at the location of the central part 12. The rows 38 extend over the entire length of the brushes 30 and are supplied by pipes 40 partially shown and which emerge from the lateral edges 33 of the end portions 13 to connect to the vehicle 1 while being loosely attached to the movable arm 2.

L'action du nettoyage est complétée par des rampes de rinçage 41 qui s'étendent sur toute la longueur du bac 11 et qui sont situées juste devant la bordure arrière 17 et éventuellement, si on prévoit une possibilité de marche arrière pour le véhicule 1, juste derrière la bordure avant 17. Les rampes de rinçage 41 sont garnies de buses 46 de projection d'eau de rinçage dirigées vers le haut et sont alimentées en eau par des tuyaux souples 42 courant parallèlement aux tuyaux 40 jusqu'au véhicule 1. Les rampes de rinçage 41 sont bien entendu souples à l'emplacement des jonctions 18. Des collerettes 43 assurent la fixation des rampes 41 au bac 11, et on peut prévoir des bordures d'étanchéité supplémentaires 44 entre les rampes 41 et les brosses 30 afin d'assurer une séparation parfaite entre les fonctions de nettoyage et de rinçage.The cleaning action is supplemented by rinsing ramps 41 which extend over the entire length of the tank 11 and which are located just in front of the rear edge 17 and possibly, if there is a possibility of reversing for the vehicle 1, just behind the front edge 17. The rinsing ramps 41 are fitted with nozzles 46 for spraying rinsing water directed upwards and are supplied with water by flexible pipes 42 running parallel to the pipes 40 to the vehicle 1. The rinsing ramps 41 are of course flexible at the location of the junctions 18. Flanges 43 ensure the fixing of the ramps 41 to the tank 11, and additional sealing edges 44 can be provided between the ramps 41 and the brushes 30 in order to '' ensure a perfect separation between the cleaning and rinsing functions.

L'évacuation des eaux usées et des salissures est effectuée par aspiration à l'aide de tuyaux d'évacuation 45 se raccordant au fond de chacune des parties 12 et 13 du bac 11 ainsi qu'un réservoir de vidange non représenté dans le véhicule.The evacuation of waste water and dirt is carried out by suction using evacuation pipes 45 connecting to the bottom of each of the parts 12 and 13 of the tank 11 as well as a drain tank not shown in the vehicle.

La mise en place de l'outil de nettoyage 10 s'effectue tout d'abord en orientant le bras mobile 2 par une action sur sa liaison 8 au véhicule 1, puis en orientant l'outil 12 face à la voûte 7 par une action sur les degrés de liberté 4 et 5 de tangage et de roulis du bras mobile 2. Le conducteur du véhicule 1 (ou le système de pilotage, dans le cas où le véhicule 1 est robotisé) est aidé par les indications de rangées de capteurs de proximité 75 situées dans le bac 11, à proximité de ses quatre coins. Chacun des capteurs de proximité 75, représenté figure 5, est constitué d'un galet 76 roulant à l'extrémité d'une bielle 77 dont l'autre extrémité est articulée à un point fixe 78 d'un corps 79 fixé au bac 11. Un piston 80 est articulé à un point intermédiaire de la bielle il comprime, en fonction du déplacement du galet 76, un fluide dont la pression ou le déplacement est mesuré. Toujours à l'aide de ces capteurs de proximité, la courbure du bac 11 est réglée à l'aide des vérins électriques 53 jusqu'à ce que la surface supérieure du bac 11 soit parfaitement parallèle à la voûte 7. Le bras mobile 2 est alors soulevé, par action sur le degré de liberté de translation verticale 3, d'une hauteur déterminée de façon à appliquer le bac 11 sur la voute 7 avec une pression connue à l'avance. Cette pression doit être suffisante pour réaliser l'étanchéité, sans être cependant trop importante car les bordures 17 seraient rapidement usées. Les brosses 30, les rangées 38 de buses et les rampes de rinçage 41 sont alors mises en marche et alimentées en liquide de façon à projeter du détergent sur la voûte 7, puis à la brosser et à la rincer. Les eaux usées et les salissures tombent dans le fond du bac 11 et sont aspirées par les tuyaux d'évacuation 45.The installation of the cleaning tool 10 is carried out firstly by orienting the movable arm 2 by an action on its connection 8 to the vehicle 1, then by orienting the tool 12 facing the arch 7 by an action on the degrees of freedom 4 and 5 of pitching and rolling of the movable arm 2. The driver of vehicle 1 (or the control system, in the case where vehicle 1 is robotized) is helped by the indications of rows of sensors of proximity 75 located in bin 11, near its four corners. Each of the proximity 75, shown in FIG. 5, consists of a roller 76 rolling at the end of a connecting rod 77, the other end of which is articulated at a fixed point 78 of a body 79 fixed to the tank 11. A piston 80 is articulated at an intermediate point of the connecting rod, it compresses, as a function of the displacement of the roller 76, a fluid whose pressure or displacement is measured. Still using these proximity sensors, the curvature of the tank 11 is adjusted using electric jacks 53 until the upper surface of the tank 11 is perfectly parallel to the arch 7. The movable arm 2 is then raised, by action on the degree of freedom of vertical translation 3, by a height determined so as to apply the container 11 to the vault 7 with a pressure known in advance. This pressure must be sufficient to achieve the seal, without however being too great because the edges 17 would quickly wear out. The brushes 30, the rows 38 of nozzles and the rinsing ramps 41 are then started and supplied with liquid so as to spray detergent on the roof 7, then to brush and rinse it. The waste water and dirt fall into the bottom of the tank 11 and are sucked in through the evacuation pipes 45.

Il est important de noter que l'outil s'adapte à des légères variations de courbure et de hauteur de la voûte 7 à l'aide tout d'abord des ressorts 62 entre le bac 11 et le bras mobile 2, à l'aide également des ressorts à lame 22 entre les différentes parties 12 et 13 du bac 11 et enfin par le fait que les différents degrés de liberté 3, 4 et 5 du bras mobile 2 peuvent être munis d'accouplements élastiques qui leur confèrent une certaine souplesse par rapport aux réglages effectués par leurs moteurs pas à pas. Si la pression de contact sur la voûte 7 devient excessive sur une partie 12 ou 13 du bac 11, cette partie s'abaisse donc vis-à-vis des autres, ce qui soulage ses bordures 17 ainsi que sa brosse 30.It is important to note that the tool adapts to slight variations in curvature and height of the arch 7 using first of all the springs 62 between the tank 11 and the movable arm 2, using also leaf springs 22 between the different parts 12 and 13 of the tank 11 and finally by the fact that the different degrees of freedom 3, 4 and 5 of the movable arm 2 can be provided with elastic couplings which give them a certain flexibility by compared to the settings made by their stepper motors. If the contact pressure on the arch 7 becomes excessive on a part 12 or 13 of the tank 11, this part therefore lowers with respect to the others, which relieves its edges 17 as well as its brush 30.

Il est cependant clair que d'autres formes de réalisation sont possibles sans s'éloigner de l'idée directrice de l'invention, qui est un outil de nettoyage permettant, au moyen d'un bac déformable et situé sur des appuis élastiques, de garantir l'étanchéité d'une action de nettoyage sur des parois de forme variable.It is however clear that other embodiments are possible without departing from the guiding idea of the invention, which is a cleaning tool making it possible, by means of a deformable container and located on elastic supports, to guarantee the tightness of a cleaning action on walls of variable shape.
