Les parties planes 1a et 1b sont toutes deux raccordées à des parois montantes 2 sensiblement verticales.The flat parts 1 a and 1 b are both connected to rising walls 2 which are substantially vertical.

Pour traiter la masse d'eau 3, le bassin 1 comporte une installation de traitement 4 bien connue dans la technique du traitement de l'eau, cette installation étant en particulier munie de filtres dans lesquels l'eau est amenée à circuler sous l'action d'au moins une pompe 5 à laquelle l'eau est amenée par un tube 6 relié au dispositif de balai 7.To treat the body of water 3, the basin 1 comprises a treatment installation 4 well known in the art of water treatment, this installation being in particular provided with filters in which the water is caused to circulate under the action of at least one pump 5 to which water is supplied by a tube 6 connected to the brush device 7.

Le dispositif de balai 7 comporte un boîtier 8 qui est creux, ouvert à sa base, et qui contient des organes décrits dans ce qui suit.The brush device 7 comprises a housing 8 which is hollow, open at its base, and which contains members described in the following.

Le boîtier 8 est relié au tube 6 par une buse de sortie 9 et un manchon 10.The housing 8 is connected to the tube 6 by an outlet nozzle 9 and a sleeve 10.

Il est avantageux que la liaison entre le boîtier et le tube 6 soit réalisée pour que le boîtier 8 puisse tourner librement par rapport au tube 6 qui doit, par ailleurs, être flexible.It is advantageous that the connection between the housing and the tube 6 is made so that the housing 8 can rotate freely relative to the tube 6 which must, moreover, be flexible.

Ce résultat peur être obtenu par différents moyens et, par exemple, comme cela est représenté.This result can be obtained by various means and, for example, as shown.

La paroi externe de la buse de sortie 9 peut être annelée, de même que la paroi externe du tube 6, et les extrémités internes du manchon 10 peuvent présenter des joncs 11 et 12 entrant dans des rainures du tube 6 et de la buse 9, ce qui fait que le manchon 10 peut tourner librement, tant par rapport à la buse de sortie 9 que par rapport au tube 6, qui peut lui-même tourner librement par rapport à ladite buse 9.The external wall of the outlet nozzle 9 can be corrugated, as can the external wall of the tube 6, and the internal ends of the sleeve 10 can have rods 11 and 12 entering grooves in the tube 6 and the nozzle 9, so that the sleeve 10 can rotate freely, both with respect to the outlet nozzle 9 and with respect to the tube 6, which can itself rotate freely with respect to said nozzle 9.

Le boîtier 8 délimite deux grands côtés 8a, 8b reliés par des côtés latéraux 13a, 13b se rejoignant par un côté dit supérieur 13.The box 8 delimits two long sides 8 a , 8 b connected by lateral sides 13 a , 13 b joining together by a so-called upper side 13.

Les côtés latéraux 13a, 13b supportent un arbre 14 pour des roues 15, 16 qui font saillie au-delà desdits côtés latéraux 13a, 13b.The lateral sides 13 a , 13 b support a shaft 14 for wheels 15, 16 which protrude beyond said lateral sides 13 a , 13 b .

Lorsque le dispositif de balayage est en fonctionnement, le boîtier 8 est maintenu dans une position pour laquelle il est vertical ou forme des petits angles (fig. 1) inférieurs à 25°.When the scanning device is in operation, the housing 8 is maintained in a position for which it is vertical or forms small angles (FIG. 1) less than 25 °.

Pour maintenir le boîtier 8 en position verticale, le dispositif prévoit un flotteur 17 qui, de préférence, est relié par friction au tube 6 mais qui pourrait aussi être relié au boîtier 8 ou au manchon 10 par un autre moyen.To maintain the housing 8 in a vertical position, the device provides a float 17 which, preferably, is frictionally connected to the tube 6 but which could also be connected to the housing 8 or to the sleeve 10 by other means.

Le flotteur 17 se présente sous la forme d'un bottier annulaire délimitant une ouverture centrale 18 de diamètre légèrement supérieur à celui du tube 6 et dans laquelle font saillie des moyens de liaison 19 par exemple des pattes en matière souple pouvant être introduites dans les rainures du tube annulaire 6 afin d'immobiliser le flotteur à un emplacement approprié par rapport à la position du boîtier 8. De cette façon, le dispositif de balai peut être maintenu dans une position sensiblement verticale même lorsqu'il est déplacé sur la partie inclinée 1b.The float 17 is in the form of an annular boot housing defining a central opening 18 of diameter slightly greater than that of the tube 6 and in which protrude from the connecting means 19, for example lugs of flexible material which can be introduced into the grooves of the annular tube 6 in order to immobilize the float at a suitable location relative to the position of the housing 8. In this way, the device broom can be kept in a substantially vertical position even when it is moved on the inclined part 1 b .

L'intérieur du flotteur 17 est rempli de mousse de matière plastique 20 ou d'un produit analogue.The interior of the float 17 is filled with plastic foam 20 or the like.

L'intérieur du boîtier 8 délimite une chambre 21 divisée en deux compartiments 21a, 21b par une cloison 22.The interior of the housing 8 delimits a chamber 21 divided into two compartments 21 a , 21 b by a partition 22.

Les fig. 2 et 7 montrent que la cloison 22 délimite un fourreau 23 mettant en communication les deux chambres 21a, 21b. Le fourreau 23 contient le corps 24 du stator 25 d'une turbine à rotor 26 dont l'admission est ainsi formée par l'ouverture dudit fourreau 23.Figs. 2 and 7 show that the partition 22 delimits a sheath 23 connecting the two chambers 21 a , 21 b . The sheath 23 contains the body 24 of the stator 25 of a rotor turbine 26 whose inlet is thus formed by the opening of said sheath 23.

Le dessin montre que le corps 24 présente une forme de révolution et se termine par des anneaux 24a, 24b engagés à frottement dans le fourreau 23 pour y être immobilisés.The drawing shows that the body 24 has a shape of revolution and ends in rings 24 a , 24 b engaged in friction in the sheath 23 to be immobilized there.

Le stator 25 comporte des aubes directrices fixes 25a et il contient un palier de butée 27 (fig. 3) prenant appui contre la turbine ou rotor 26.The stator 25 has fixed guide vanes 25 a and it contains a thrust bearing 27 (fig. 3) bearing against the turbine or rotor 26.

La turbine ou rotor 26, qui est du type axial, est porté par un arbre 28 sur lequel est calé angulairement un rotor 26.The turbine or rotor 26, which is of the axial type, is carried by a shaft 28 on which a rotor 26 is wedged angularly.

Dans la pratique, il est avantageux que le stator 25 comme le rotor 26 soient réalisés en matière plastique, tandis que l'arbre 28 et le palier de butée 27 sont de préférence réalisés en métal. Le palier est inséré dans le stator 25 pour être protégé, par suite, des impuretés qui peuvent traverser la turbine lors du fonctionnement du dispositif.In practice, it is advantageous that the stator 25 as the rotor 26 are made of plastic, while the shaft 28 and the thrust bearing 27 are preferably made of metal. The bearing is inserted in the stator 25 to be protected, as a result, from impurities which may pass through the turbine during operation of the device.

Le montage décrit ci-dessus fait que la turbine ou rotor 26 est centré par le stator 25 qui est lui-même centré dans le fourreau 23, ce qui assure un fonctionnement parfaitement régulier particulièrement lorsque l'arbre 28 est réalisé en une matière plastique par exemple en polyamide présentant une certaine souplesse pour compenser d'éventuels défauts mineurs d'alignement.The assembly described above means that the turbine or rotor 26 is centered by the stator 25 which is itself centered in the sheath 23, which ensures perfectly smooth operation, particularly when the shaft 28 is made of a plastic material. example in polyamide having a certain flexibility to compensate for possible minor misalignments.

Le dessin, en particulier la fig. 2, montre que l'arbre 28 entraîne un mécanisme réducteur et de transmission 29 dont l'engrenage de sortie 29a est calé ou autrement relié à l'arbre 14 d'entraînement des roues 15, 16.The drawing, in particular fig. 2, shows that the shaft 28 drives a reduction and transmission mechanism 29, the output gear 29a of which is stalled or otherwise connected to the shaft 14 for driving the wheels 15, 16.

Il est avantageux, ainsi que l'illustre le dessin, que le réducteur 29 soit logé dans des carters 30, 30a rapporté sur le côté latéral 13b du boîtier 8, par exemple, au moyen de vis 31 pouvant, comme les autres parties du dispositif, être réalisées en matière plastique.It is advantageous, as illustrated by the drawing, that the gear unit 29 is housed in the housings 30, 30 is attached to the lateral side 13b of the housing 8, for example, by means of screws 31 that can, like the other parts of the device, be made of plastic.

Le compartiment 21b de la chambre 21 contient un tamis de filtrage 32 dont la face antérieure 33 ferme complètement le côté libre du boîtier 8, c'est-à-dire que la face 33 s'étend de l'un à l'autre des côtés latéraux 13a, 13b en épousant le carter 30a, ce qui est illustré par la fig. 3.The compartment 21b of the chamber 21 contains a filtering screen 32 whose front face 33 completely closes the free side of the housing 8, that is to say that the face 33 extends from one to the other lateral sides 13 a , 13 b by marrying the casing 30 a , which is illustrated in FIG. 3.

La face antérieure 33 du tamis est formée à partir d'une plaque 34 formant couvercle pour la fermeture du compartiment 21b.The front face 33 of the screen is formed from a plate 34 forming a cover for closing the compartment 21b .

La plaque 34 et la face antérieure 33 sont formées d'une pièce avec une paroi perforée 36 conformée pour épouser approximativement les côtés du boîtier 8 et de la cloison 22 délimitant le compartiment 21b.The plate 34 and the front face 33 are formed in one piece with a perforated wall 36 shaped to approximate the sides of the housing 8 and of the partition 22 delimiting the compartment 21b.

La paroi perforée 36 est reliée de même que la face antériewe 33 à un fond amovible 37.The perforated wall 36 is connected, like the front face 33, to a removable bottom 37.

Le fond amovible 37 est constitué par une plaque présentant des doigts 38 engagés dans des trous de la face antérieure 33, ledit fond 37 étant, par ailleurs, maintenu dans la paroi perforée 36 au aryen d'une patte 39 formant verrou.The removable bottom 37 is constituted by a plate having fingers 38 engaged in holes in the front face 33, said bottom 37 being, moreover, held in the perforated wall 36 with the aryan of a tab 39 forming a lock.

Pour faciliter la mise en place et le retrait de la patte 39 et par conséquent pour faciliter le montage et le démontage du fond 37, il est avantageux, d'une part, que la patte 39 soit souple et, d'autre part, que des fentes 40 (fig. 3) soient pratiquées dans la paroi perforée 36 afin que celle-ci soit elle-même déformable élastiquement.To facilitate the establishment and removal of the lug 39 and therefore to facilitate the mounting and dismounting of the bottom 37, it is advantageous, on the one hand, that the lug 39 is flexible and, on the other hand, that slots 40 (FIG. 3) are made in the perforated wall 36 so that the latter is itself elastically deformable.

Ce qui précède montre que le tamis de filtrage délimite une cavité interne 41 qui communique avec le compartiment 21b par les perforations de la paroi perforée 36.The above shows that the filtering screen delimits an internal cavity 41 which communicates with the compartment 21b through the perforations of the perforated wall 36.

La cavité interne 41 communique en outre avec l'extérieur au moyen d'un clapet 42 porté par la face antérieure 33, ce clapet étant constitué, par exemple, par une lame élastique en élastomère ou matière analogue.The internal cavity 41 further communicates with the outside by means of a valve 42 carried by the front face 33, this valve being constituted, for example, by an elastic blade of elastomer or similar material.

La description qui précède montre que l'ensemble du tamis de filtrage 32 est porté par la plaque 34 formant couvercle et le dessin illustre que la plaque 34 est munie de redents 43 et 44 (fig. 4 et 5).The above description shows that the entire filter screen 32 is carried by the plate 34 forming a cover and the drawing illustrates that the plate 34 is provided with redents 43 and 44 (FIGS. 4 and 5).

Les redents 44 sont destinés à être engagés en dessous du grand côté 8b du boîtier 8 (fig. 2) tandis que le redent 43 est destiné à être engagé en dessous d'une réglette 45 saillant de la cloison 22, ce qui est illustré en particulier par la fig. 4 qui montre, ainsi que la fig. 4a, que la plaque 34 formant couvercle vient en butée contre l'extrémité saillante 13₁ des côtés latéraux 13a, 13b lorsque ledit couvercle est en place.The redents 44 are intended to be engaged below the long side 8b of the housing 8 (fig. 2) while the redent 43 is intended to be engaged below a strip 45 projecting from the partition 22, which is illustrated in particular by fig. 4 which shows, as well as FIG. 4 a , that the cover plate 34 comes into abutment against the projecting end 13₁ of the lateral sides 13 a, 13 b when said cover is in place.

Outre ce qui précède, le dispositif est muni, à sa partie inférieure, d'une unité de balayage 46.In addition to the above, the device is provided, at its lower part, with a scanning unit 46.

Dans l'exemple représenté, l'unité de balayage 46 comporte deux traverses 47 reliées par des barrettes 48, de préférence lestées comme montré en 48a.In the example shown, the scanning unit 46 comprises two crosspieces 47 connected by bars 48, preferably ballasted as shown at 48 a .

Les barrettes 48 supportent des balais 49.The bars 48 support brushes 49.

L'une des barrettes 48 est engagée dans une encoche 50 du grand côté 8a du boîtier 8. L'autre barrette 48 est munie de doigts 51 engagés dans des encoches 52 des côtés latéraux 13a, 13b du boîtier 8 pour être maintenus verrouillés par le couvercle 34 lorsque celui-ci est en place.One of the bars 48 is engaged in a notch 50 on the long side 8 a of the housing 8. The other bar 48 is provided with fingers 51 engaged in notches 52 on the lateral sides 13 a , 13 b of the housing 8 to be maintained locked by the cover 34 when the latter is in place.

Comme le montre en particulier la fig. 4a, la Largeur des encoches 50 et 52 est notablement plus grande que la partie correspondante des barrettes 48 et doigts 51 de manière que l'unité de balayage 46 puisse jouer et être déplacée d'une relativement grande amplitude, par exemple jusqu'à 5 mm par rapport au boîtier.As shown in particular in fig. 4 a , the width of the notches 50 and 52 is notably greater than the corresponding part of the bars 48 and fingers 51 so that the scanning unit 46 can play and be moved by a relatively large amplitude, for example up to 5 mm from the housing.

La longueur des balais 49 est choisie compte tenu de la position des roues 15, 16, de manière que l'une d'elles soit toujours en appui contre le sol quelle que soit la position angulaire que peut occuper le dispositif de balayage par rapport aux parties planes ou inclinées du bassin 1.The length of the brushes 49 is chosen taking into account the position of the wheels 15, 16, so that one of them is always in abutment against the ground whatever the angular position that the scanning device may occupy relative to the flat or inclined parts of the pelvis 1.

Outre ce qui précède, le dispositif comporte un clapet de réglage 53 (fig. 3) pouvant être commandé à partir d'une tête 54 (fig. 2) pour établir un passage éventuel entre les compartiments 21a, 21b du boîtier 8.In addition to the above, the device includes an adjustment valve 53 (fig. 3) which can be controlled from a head 54 (fig. 2) to establish a possible passage between the compartments 21 a , 21 b of the housing 8.

La fig. 3 montre que le clapet de réglage 53 est constitué par une clé disposée dans un logement 55 de la cloison 22.Fig. 3 shows that the adjustment valve 53 is constituted by a key arranged in a housing 55 of the partition 22.

En tournant plus ou moins la tête 54, il est possible d'établir ou non un passage de l'un à l'autre des compartiments 21a, 21b, ce qui est réalisé en dépendance de la dépression pouvant être produite par la pompe 5 de l'installation de traitement 4.By turning the head 54 more or less, it is possible to establish or not a passage from one to the other of the compartments 21 a , 21 b , which is carried out in dependence on the vacuum that can be produced by the pump. 5 of the treatment plant 4.

Le dispositif de balayage décrit ci-dessus fonctionne de la façon suivante :The scanning device described above operates as follows:

Lorsque la poque 5 est en fonctionnement, de l'eau est aspirée par le tube 6, ce qui produit une dépression dans le compartiment 21a du boîtier 8.When the time 5 is in operation, water is sucked through the tube 6, which produces a vacuum in the compartment 21 a of the housing 8.

De l'eau est par conséquent aspirée pour être refoulée dans l'installation de traitement 4 puis ensuite, faire retour au bassin 1 d'une manière connue.Water is therefore sucked up to be discharged into the treatment installation 4 and then return to the basin 1 in a known manner.

Le boîtier 8 est ouvert seulement à sa partie inférieure entre les balais 49, c'est-à-dire par le passage laissé libre entre les barrettes 48.The housing 8 is open only at its lower part between the brushes 49, that is to say by the passage left free between the bars 48.

L'eau du bassin ne peut être aspirée qu'en soulevant le clapet 42 par lequel elle entre dans la cavité interne 41 du tamis de filtrage 32.The water in the basin can only be aspirated by lifting the valve 42 by which it enters the internal cavity 41 of the filter screen 32.

Les impuretés sont retenues dans la cavité 41, l'eau traversant la paroi perforée 36 et étant ainsi conduite à l'admission, donc aux aubes directrices 25a du stator 25 de turbine.The impurities are retained in the cavity 41, the water passing through the perforated wall 36 and thus being led to the inlet, therefore to the guide vanes 25 a of the stator 25 of the turbine.

Le courant d'eau en circulation entraîne le rotor de turbine 26 puis est ramené à la buse 9, au tube 6, à la pompe 5 et à l'installation de traitement 4.The current of circulating water drives the turbine rotor 26 and is then returned to the nozzle 9, to the tube 6, to the pump 5 and to the treatment installation 4.

La rotation de la turbine 26 a pour effet d'entraîner l'arbre 28 dont le mouvement est démultiplié par le mécanisme réducteur et de transmission 29 qui entraîne l'engrenage de sortie 29a et, par conséquent, l'arbre 14 et les roues 15, 16.The rotation of the turbine 26 has the effect of driving the shaft 28 whose movement is increased by the reduction and transmission mechanism 29 which drives the output gear 29 a and, consequently, the shaft 14 and the wheels 15, 16.

La rotation des roues 15, 16 a pour effet de déplacer l'ensemble du dispositif de balayage 7 sur le fond du bassin, l'un au moins des balais 49 frottant le fond et détachant, par conséquent, les impuretés qui sont aspirées et retenues dans la cavité 41 du tamis de filtrage 32.The rotation of the wheels 15, 16 has the effect of displacing the whole of the sweeping device 7 on the bottom of the basin, at least one of the brushes 49 rubbing the bottom and detaching, consequently, the impurities which are sucked in and retained in the cavity 41 of the filter screen 32.

Le lest 48a dont sont munies les barrettes 48 assure une application appropriée des balais sur le sol et cela sans qu'il en résulte des pertes d'adhérence des roues 15, 16 puisque l'unité de balayage 46 peut jouer par rapport au boîtier 8 auquel elle est reliée par les barrettes 48 et les parois des encoches 50 et 52.The ballast 48 a with which the bars 48 are provided ensures an appropriate application of the brushes on the ground and this without this resulting in losses of adhesion of the wheels 15, 16 since the scanning unit 46 can play relative to the housing 8 to which it is connected by the bars 48 and the walls of the notches 50 and 52.

Après un long usage, le dispositif de balayage peut être facilement nettoyé en le sortant du bassin 1 et en le démontant. Comme l'illustre la fig. 4, il y a lieu tout d'abord de soulever légèrement la plaque 34 formant couvercle pour qu'elle échappe de l'extrémité saillante 13₁ des côtés latéraux 13a, 13b.After long use, the sweeping device can be easily cleaned by removing it from the basin 1 and dismantling it. As illustrated in fig. 4, it is necessary firstly to slightly lift the lid plate 34 so that it escapes from the projecting end 13₁ of the lateral sides 13 a, 13 b.

Ensuite les redents 44 sont dégagés respectivement de la réglette 45 et du grand côté 8b, ce qui permet de faire pivoter l'ensemble du tamis de filtrage comme l'illustre la fig. 4 pour l'extraire du compartiment 21b.Then the steps 44 are released respectively from the strip 45 and the large side 8b , which allows to rotate the whole of the filter screen as illustrated in FIG. 4 to extract it from compartment 21 b .

Pour nettoyer le tamis de filtrage, on exerce une traction sur la patte 39 formant verrou en même temps que l'on exerce une légère poussée sur la paroi du tamis de filtrage pour la déformer élastiquement grâce aux fentes 40 (fig. 3 et 5).To clean the filter screen, a pull is exerted on the tab 39 forming a lock at the same time as a light push is exerted on the wall of the filter screen to deform it elastically thanks to the slots 40 (fig. 3 and 5) .

Lorsque le doigt 39 est dégagé, les doigts 38 peuvent être extraits de sorte que le fond 37 est retiré et que les impuretés retenues à l'intérieur du tamis de filtrage peuvent être évacuées.When the finger 39 is released, the fingers 38 can be removed so that the bottom 37 is removed and the impurities retained inside the filter screen can be removed.

Pour démonter l'unité de balai 46 après retrait du tamis de filtrage, il suffit de faire glisser les doigts 51 en dehors des encoches 52, ce qui fait échapper la barrette 48 de l'encoche 50.To dismantle the brush unit 46 after removal of the filtering screen, it suffices to slide the fingers 51 outside the notches 52, which causes the bar 48 to escape from the notch 50.

Après retrait du tamis de filtrage 32, l'ensemble de la turbine peut être démonté en exerçant une poussée sur le rotor de turbine 26 par exemple en agissant par un doigt de la main dans le sens de la flèche de la fig. 7.After removal of the filter screen 32, the entire turbine can be removed by exerting a push on the turbine rotor 26, for example by acting with a finger of the hand in the direction of the arrow in FIG. 7.

Cette poussée, facilitée par une encoche 56 prévue dans le fourreau 23, est transmise au corps de turbine 24 qui glisse jusqu'au compartiment 21b en même temps que le rotor de turbine 26 qui est lui-même dégagé de l'arbre 28.This thrust, facilitated by a notch 56 provided in the sheath 23, is transmitted to the turbine body 24 which slides to the compartment 21b at the same time as the turbine rotor 26 which is itself released from the shaft 28.

Après nettoyage, les pièces sont remises en place en procédant de manière opposée à ce qui vient d'être décrit, lesdites pièces se verrouillant mutuellement.After cleaning, the parts are replaced by proceeding in the opposite manner to what has just been described, said parts locking each other.

Suivant la variante des fig. 8 et 9, les mêmes numéros de référence désignent les mêmes organes qu'aux figures précédentes.According to the variant of FIGS. 8 and 9, the same reference numbers designate the same members as in the preceding figures.

A la fig. 8, le boîtier 8 est ouvert sur chacun de ses deux côtés latéraux 8₁, 8₂.In fig. 8, the housing 8 is open on each of its two lateral sides 8₁, 8₂.

Sur le côté latéral 8₁, le boîtier 8 reçoit un couvercle 57 fixé par emboîtement et retenu par encliquetage, friction ou autre moyen de la technique. Le couvercle 57 supporte le tamis de filtrage 32 qui est simplement emboîté à l'intérieur du boîtier 8 et dont la partie perforée est conformée pour être compatible avec la forme interne du boîtier 8 et de la cloison 22.On the lateral side 8₁, the housing 8 receives a cover 57 fixed by interlocking and retained by snap-fastening, friction or other means of the technique. The cover 57 supports the filter screen 32 which is simply fitted inside the housing 8 and the part of which perforated is shaped to be compatible with the internal shape of the housing 8 and the partition 22.

Dans l'exemple représenté, le tamis de filtrage 32 est également emboîté dans le couvercle 57 et ce tamis de filtrage ne présente pas de fond.In the example shown, the filter screen 32 is also fitted into the cover 57 and this filter screen has no bottom.

Dans cette réalisation, le boîtier 8 comporte un fond 8′ qui est muni de deux clapets 42a, 42b disposés en regard des conduits d'entrée 58, 59 formés par des déflecteurs 58a, 58b et 59a, 59b du boîtier. Les déflecteurs ci-dessus délimitent les conduits d'entrée 58, 59 disposés au-dessus de deux jeux de balais 49a, 49b réalisés comme décrit en référence aux figures précédentes en ce qui concerne le balai 49.In this embodiment, the housing 8 has a bottom 8 ′ which is provided with two valves 42 a , 42 b arranged opposite the inlet conduits 58, 59 formed by deflectors 58 a , 58 b and 59 a , 59 b of the housing. The above deflectors delimit the inlet conduits 58, 59 arranged above two sets of brushes 49 a , 49 b produced as described with reference to the preceding figures as regards the brush 49.

La disposition qui précède permet le montage d'une roue médiane 60 sur l'arbre 14.The above arrangement allows the mounting of a central wheel 60 on the shaft 14.

De préférence et comme représenté, la roue 60 est de diamètre légèrement plus petit que celui des roues 15, 16. De cette manière, la roue 60 ne porte pas constamment sur le fond du bassin mais s'il advient qu'un obstacle, par exemple une crépine faisant saillie du fond du bassin, se trouve sur la trajectoire des biellettes 49a, 49b, alors la roue 60 venant heurter l'obstacle peut rouler sur celui-ci en entraînant l'ensemble du dispositif de balayage qui pourrait autrement être immobilisé si l'une des roues 15 ou 16 était soulevée et que cette roue soit justement une roue motrice.Preferably and as shown, the wheel 60 is of slightly smaller diameter than that of the wheels 15, 16. In this way, the wheel 60 does not constantly bear on the bottom of the basin but if it happens that an obstacle, for example a strainer protruding from the bottom of the basin, is on the trajectory of the links 49 a , 49 b , then the wheel 60 striking the obstacle can roll thereon driving the entire scanning device which could otherwise be immobilized if one of the wheels 15 or 16 was raised and this wheel is precisely a driving wheel.

Le côté latéral ouvert 8₂ du boîtier 8 reçoit par emboîtement une buse 61 qui est elle-même emboîtée dans un logement 62 que délimite un couvercle 63 qui est, d'une part, emboîté sur la buse 61 et, d'autre part, relié au boîtier 8 par des pattes 64 ou autres organes analogues.The open lateral side 8₂ of the housing 8 receives by fitting a nozzle 61 which is itself fitted into a housing 62 which delimits a cover 63 which is, on the one hand, fitted onto the nozzle 61 and, on the other hand, connected to the housing 8 by lugs 64 or other similar members.

La buse 61 emboîtée dans l'ouverture 8b du boîtier 8 est aussi emboîtée dans le fourreau 23 que forme la cloison 22. Le fourreau 23 et la buse 61 supportent le corps 24 contenant le stator 25 et les aubes directrices 25a pour diriger l'eau devant entraîner le rotor de la turbine axiale 26.The nozzle 61 fitted into the opening 8b of the housing 8 is also fitted into the sheath 23 formed by the partition 22. The sheath 23 and the nozzle 61 support the body 24 containing the stator 25 and the guide vanes 25 a for directing the water to drive the rotor of the axial turbine 26.

Dans cette réalisation, le rotor de la turbine axiale 26 est supporté par l'arbre 28 par rapport auquel il peut tourner et coulisser librement contrairement à ce qui est décrit en référence aux figures précédentes.In this embodiment, the rotor of the axial turbine 26 is supported by the shaft 28 with respect to which it can rotate and slide freely contrary to what is described with reference to the previous figures.

L'arbre 28 porte un manchon 65 qui lui est rigidement connecté pour que ledit manchon soit solidaire en rotation de l'arbre 28 et un ressort hélicoîdal 66 est interposé entre le manchon 65 et le rotor de turbine axiale 26.The shaft 28 carries a sleeve 65 which is rigidly connected to it so that said sleeve is integral in rotation with the shaft 28 and a helical spring 66 is interposed between the sleeve 65 and the axial turbine rotor 26.

Le sens de rotation de la turbine 26 et le sens d'enroulement du ressort hélicoîdal 66 sont de préférence les mêmes.The direction of rotation of the turbine 26 and the direction of winding of the helical spring 66 are preferably the same.

Le ressort hélicoîdal 66 exerce une poussée sur la turbine 26 pour tendre à la maintenir contre le palier de butée 27 (fig. 9) et il est fixé, d'une part, à ladite turbine et, d'autre part, au manchon 65 par chacune de ses extrémités.The helical spring 66 pushes on the turbine 26 to tend to hold it against the thrust bearing 27 (fig. 9) and it is fixed, on the one hand, to said turbine and, on the other hand, to the sleeve 65 by each of its ends.

Le manchon 65, qui traverse le fond 62a du logement 62, est relié par un pignon 67 au réducteur 29 décrit dans ce qui précède.The sleeve 65, which passes through the bottom 62 a of the housing 62, is connected by a pinion 67 to the reduction gear 29 described in the foregoing.

La description ci-dessus fait apparaître que les éléments qui constituent la buse 61, le corps 24, la turbine 25, 26 et le couvercle 63 qui contient le réducteur 29 constituent un ensemble pouvant être facilement monté et démonté et qui est, par conspuent, interchangeable. Par ailleurs, cet ensemble est lui-même facilement démontable puisque la buse 61 est emboîtée dans le couvercle 63, ce qui rend possible un nettoyage éventuel facile du rotor de turbine 26 et des aubes 25a du stator 25 ainsi que des autres pièces, par exemple le ressort 66.The above description shows that the elements which constitute the nozzle 61, the body 24, the turbine 25, 26 and the cover 63 which contains the reducer 29 constitute an assembly which can be easily assembled and disassembled and which is, by conspuent, interchangeable. Furthermore, this set is itself easily removable since the nozzle 61 is fitted into the cover 63, which makes possible easy cleaning of the turbine rotor 26 and of the blades 25 a of the stator 25 as well as of the other parts, for example the spring 66.

Le fonctionnement du mode de réalisation suivant les fig. 8 et 9 est le même que décrit dans ce qui précède, à cette exception toutefois que le tube d'aspiration 6 peut être branché sur une pompe 5 de puissance très variable sans qu'il y ait lieu de procéder à aucun réglage du dispositif. En effet, lorsque la puissance d'aspiration est faible, l'eau ayant traversé le tamis de filtrage 32 passe entre les aubes directrices 25a puis entraîne en rotation le rotor de turbine axiale 26 qui transmet ce mouvement de rotation par le ressort 66 au manchon 65 et, par conséquent, au réducteur 29, de sorte que l'arbre 14 des roues 15, 16, 60 est entraîné.The operation of the embodiment according to FIGS. 8 and 9 is the same as described in the foregoing, with the exception however that the suction tube 6 can be connected to a pump 5 of very variable power without there being any need to make any adjustment to the device. In fact, when the suction power is low, the water having passed through the filtering screen 32 passes between the guide vanes 25a and then rotates the axial turbine rotor 26 which transmits this rotational movement by the spring 66 to the sleeve 65 and, consequently, the reduction gear 29, so that the shaft 14 of the wheels 15, 16, 60 is driven.

Si la vitesse d'aspiration de l'eau par le tube 6 croît, notamment lorsque la pompe 5 est très puissante, alors l'eau qui est dirigée vers la turbine tend à entraîner celle-ci à une vitesse plus élevée mais elle exerce aussi sur les aubes du rotor une pression plus élevée.If the speed of suction of water through the tube 6 increases, especially when the pump 5 is very powerful, then the water which is directed towards the turbine tends to drive the latter at a higher speed but it also exerts higher pressure on the rotor blades.

Si la pression dépasse la force sous laquelle la turbine est appliquée contre le palier de butée 27 par le ressort 66, celui-ci est comprimé et, par conséquent, la turbine 26 est écartée du palier de butée 27, de sorte qu'un effet de by-pass a lieu et que de l'eau s'échappe radialement entre le stator constitué par les aubes directrices 25a et le rotor de turbine axiale 26, ce qui est illustré par la flèche à la fig. 9.If the pressure exceeds the force under which the turbine is applied against the thrust bearing 27 by the spring 66, the latter is compressed and, consequently, the turbine 26 is moved away from the thrust bearing 27, so that an effect of bypass takes place and that water escapes radially between the stator constituted by the guide vanes 25 a and the axial turbine rotor 26, which is illustrated by the arrow in FIG. 9.

Plus la pression est élevée, plus grand est l'écart entre le stator et le rotor et, par conséquent, la vitesse de la turbine 26 est maintenue sensiblement constante, d'où il découle que la vitesse de déplacement du dispositif de balai est également sensiblement constante et indépendante de la puissance de la pompe 5.The higher the pressure, the greater the difference between the stator and the rotor and, consequently, the speed of the turbine 26 is kept substantially constant, from which it follows that the speed of movement of the device brush is also substantially constant and independent of the power of pump 5.

Suivant la variante de la fig. 10, le tamis 32 comprend une surface de fond pleine 33 qui ferme le côté ouvert du boîtier 8 comme à la fig. 3.According to the variant of FIG. 10, the screen 32 includes a solid bottom surface 33 which closes the open side of the housing 8 as in FIG. 3.

Le tamis 32 est conformé pour délimiter un canal interne 70 qui, de préférence, est délimité par une cloison 71 en forme de U réalisé de façon monobloc avec la surface de fond 33 et la paroi arrière 33a du tamis.The screen 32 is shaped to delimit an internal channel 70 which, preferably, is delimited by a U-shaped partition 71 made in one piece with the bottom surface 33 and the rear wall 33 a of the screen.

Le canal 70 est ouvert à son extrémité opposée à la paroi arrière 33a pour communiquer avec l'intérieur du couvercle 57 et l'intérieur du tamis.The channel 70 is open at its end opposite the rear wall 33 a to communicate with the interior of the cover 57 and the interior of the screen.

La surface de fond 33 est munie de clapets 42a, 42b analogues à ceux décrits dans ce qui précède, clapets qui ouvrent dans ledit canal 70.The bottom surface 33 is provided with valves 42 a , 42 b similar to those described in the foregoing, valves which open in said channel 70.

Le tamis 32 est ouvert sur son côté latéral qui correspond au côté latéral 8₁ du boîtier 8 dans lequel il est engagé et retenu par friction ou encliquetage ou un autre moyen amovible de la technique.The screen 32 is open on its lateral side which corresponds to the lateral side 8₁ of the housing 8 in which it is engaged and retained by friction or snap-fastening or another removable means of the technique.

Comme représenté par la fig. 10, lorsque l'eau est aspirée par le tube 6, cette eau est aspirée à travers les clapets 42a, 42b et le canal 70 suivant les flèches. L'eau passe ensuite dans le couvercle 57 vers l'intérieur du tamis 32 et le compartiment 21a pour atteindre le tube 6.As shown in fig. 10, when the water is sucked through the tube 6, this water is sucked through the valves 42 a , 42 b and the channel 70 according to the arrows. The water then passes through the cover 57 towards the inside of the screen 32 and the compartment 21 a to reach the tube 6.

Pour le nettoyage, le couvercle 57 est démonté et le tamis extrait du boîtier 8 pour être soulevé.For cleaning, the cover 57 is removed and the sieve extracted from the housing 8 to be lifted.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, le mécanisme réducteur et de transmission 29 peut être muni d'un inverseur de marche déclenché lorsque le boîtier 8 heurte un obstacle ou en fonction d'un autre paramètre. De même, l'une des roues 16 ou 17 peut être entraînée par l'intermédiaire d'une roue libre ou d'un limiteur de couple pour permettre au boîtier 8 de pivoter lorsqu'il heurte un obstacle. Les mécanismes de roue libre, de même que les mécanismes d'inversion de marche étant bien connus en eux-mêmes, il n'est pas apparu utile de les représenter, ni de les décrire en détail.The invention is not limited to the embodiments shown and described in detail, since various modifications can be made without departing from its scope. In particular, the reduction and transmission mechanism 29 can be provided with a gear reverser triggered when the housing 8 strikes an obstacle or as a function of another parameter. Similarly, one of the wheels 16 or 17 can be driven via a free wheel or a torque limiter to allow the housing 8 to pivot when it strikes an obstacle. The freewheeling mechanisms, as well as the reverse mechanisms being well known in themselves, it did not appear useful to represent them, or to describe them in detail.
