Par intervention il faut entendre, notamment, la mise en place d'un ensemble, le remplacement d'un ensemble défaillant, ou le remplacement d'un ensemble par un autre ensemble de fonctionnalité différente.The purpose of the submerged device according to the invention is to insulate said functional assembly from the aqueous medium of the swimming pool, while preserving the possibility of interventions on this assembly outside the swimming pool. By intervention is meant, in particular, the establishment of an assembly, the replacement of a failed assembly, or the replacement of an assembly by another assembly of different functionality.
L'invention a donc pour objet un dispositif immergé pour piscine, disposé de façon étanche dans un orifice, qui traverse la paroi de la piscine, caractérisé par le fait qu' il comporte :The subject of the invention is therefore a submerged device for a swimming pool, disposed in a sealed manner in an orifice which crosses the wall of the swimming pool, characterized in that it comprises:
- un boîtier cylindrique, dont l'ouverture affleure au voisinage de la face de ladite paroi, qui est du côté de l'intérieur de la piscine, et dont le fond est au voisinage de l'autre face de ladite paroi, - des moyens de séparation portés par ledit boîtier et disposés dans l'ouverture dudit boîtier, et- a cylindrical housing, the opening of which is flush in the vicinity of the face of said wall, which is on the side of the interior of the swimming pool, and the bottom of which is in the vicinity of the other face of said wall, - means separation carried by said housing and arranged in the opening of said housing, and
- une gaine étanche reliant le fond du boîtier auxdits moyens de séparation, et susceptible de permettre, à l'intérieur de ladite gaine, le passage hors d'eau d'au moins un câble électrique depuis les moyens de séparation jusqu'à l'extérieur de la piscine, ladite gaine étant d'une longueur suffisante pour que lesdits moyens de séparation puissent être remontés au-dessus du niveau d'eau de la piscine sans démontage de la gaine et le boîtier définissant un volume intérieur suffisant pour y loger la gaine entre les moyens de séparation et le fond du boîtier. On peut prévoir que l' intérieur du boîtier et l'intérieur de la piscine soient en communication hydraulique ; de préférence, entre le boîtier et les moyens de séparation est prévue au moins une fente ménagée sur au moins une partie du pourtour de l'ouverture du boîtier pour le passage de l'eau entre la piscine et l'intérieur du boîtier. De la sorte, il n'y a aucune difficulté pour séparer du boîtier les moyens de séparation qui sont fixés sur son ouverture, quelque soit la profondeur sous l'eau où se trouve le dispositif.- A sealed sheath connecting the bottom of the housing to said separation means, and capable of allowing, inside said sheath, the passage out of water of at least one electric cable from the separation means to the exterior of the swimming pool, said sheath being of sufficient length for said separation means to be able to be raised above the water level of the swimming pool without disassembly of the sheath and the housing defining an interior volume sufficient to accommodate the sheath between the separation means and the bottom of the housing. Provision may be made for the interior of the housing and the interior of the swimming pool to be in hydraulic communication; preferably, between the housing and the separation means is provided at least one slot formed on at least part of the periphery of the opening of the housing for the passage of water between the pool and the interior of the housing. In this way, there is no difficulty in separating from the housing the separation means which are fixed on its opening, whatever the depth under water where the device is located.
Les moyens de séparation entre l ' intérieur du boîtier et la piscine sont constitués alternativement par un compartiment étanche ou par un cache.The separation means between the interior of the housing and the swimming pool are alternately constituted by a sealed compartment or by a cover.
Avantageusement, le compartiment étanche et le cache sont assemblés avec une cloche sur laquelle se fixe l'une des extrémités de la gaine ; la cloche peut être fixée sur l'enceinte ou sur le cache avec interposition d'un joint d'étanchéité.Advantageously, the sealed compartment and the cover are assembled with a bell on which one of the ends of the sheath is fixed; the bell can be fixed on the enclosure or on the cover with the interposition of a seal.
De préférence, le boîtier présente des renforcements d'épaisseur répartis sur le pourtour de son ouverture, pour la fixation des moyens de séparation ; une collerette annulaire peut être fixée sur le pourtour de l'ouverture du boîtier pour masquer la paroi de la piscine autour de l'orifice et éventuellement pour masquer l'étanchéité mise en place entre le boîtier et l'orifice.Preferably, the housing has thickness reinforcements distributed around the periphery of its opening, for fixing the separation means; an annular flange can be fixed on the periphery of the opening of the housing to mask the wall of the swimming pool around the orifice and possibly to hide the seal put in place between the housing and the orifice.
La gaine est, par exemple, enroulée en hélice dans le boîtier, contre la paroi cylindrique dudit boîtier ; elle relie, de préférence, le fond du boîtier aux moyens de séparation grâce à au moins un raccord étanche.The sheath is, for example, wound helically in the housing, against the cylindrical wall of said housing; it preferably connects the bottom of the housing to the separation means by means of at least one sealed connection.
Le compartiment étanche est constitué, de préférence, d'un globe, formant avantageusement un relief arrondi dans la piscine, et d'une cuvette, assemblés le long de leurs bordures libres avec interposition d'un joint d'étanchéité, la mise en place du compartiment dans l'ouverture du boîtier s'effectuant en disposant le globe vers l'intérieur de la piscine, la cloche étant fixée sur le fond de la cuvette. La cuvette porte avantageusement sur son fond, du côté de la cloche, un connecteur relié à l'intérieur du compartiment, ledit connecteur étant susceptible de coopérer avec un connecteur complémentaire porté par le(s) câble(s) électrique(s) qui traverse(nt) la gaine. Le fond de la cuvette peut aussi porter des raccords à clapet permettant la mise sous atmosphère contrôlée de l'intérieur du compartiment.The watertight compartment is preferably made up of a globe, advantageously forming a rounded relief in the pool, and a bowl, assembled along their free edges with the interposition of a seal, placing of the compartment in the opening of the housing being effected by placing the globe towards the interior of the swimming pool, the bell being fixed on the bottom of the bowl. The bowl advantageously carries on its bottom, on the side of the bell, a connector connected inside the compartment, said connector being capable of cooperating with a complementary connector carried by the electrical cable (s) which passes through (nt) the sheath. The bottom of the bowl can also carry valve fittings allowing the interior of the compartment to be placed under a controlled atmosphere.
La gaine peut contenir, outre les câbles électriques qui la traversent, un fil en attente constituant une "aiguille" pour l'introduction d'un nouveau câble dans la gaine sans qu'il soit nécessaire de déconnecter la gaine par rapport au boîtier.The sheath may contain, in addition to the electric cables which pass through it, a waiting wire constituting a "needle" for the introduction of a new cable into the sheath without it being necessary to disconnect the sheath relative to the housing.
Avantageusement, le moyen de séparation est un compartiment étanche contenant un ensemble fonctionnel, connecté électriquement avec l'extérieur par un connecteur, qui coopère avec un connecteur complémentaire monté sur le câble, le connecteur du compartiment étanche étant porté par le fond de la cuvette ; le compartiment étanche contient un ensemble fonctionnel électronique, optique ou sonique : l'ensemble contenu dans le compartiment peut être constitué par un projecteur lumineux, une caméra, un sonar, un capteur pour effectuer une télémétrie par laser, ou un appareil de sonorisation.Advantageously, the separation means is a sealed compartment containing a functional assembly, electrically connected with the outside by a connector, which cooperates with a complementary connector mounted on the cable, the connector of the sealed compartment being carried by the bottom of the bowl; the watertight compartment contains an electronic, optical or sonic functional unit: the unit contained in the compartment can be constituted by a light projector, a camera, a sonar, a sensor for performing laser telemetry, or a sound device.

D'autres caractéristiques ressortent de la description, qui suit, faite en se référant au dessin annexé. Sur ce dessin :Other characteristics will emerge from the description which follows, made with reference to the appended drawing. On this drawing :
- la figure 1 est une vue en coupe axiale d'un exemple de réalisation d'un dispositif immergé pour piscine selon l'invention équipé d'un compartiment contenant un ensemble fonctionnel, le haut de la piscine étant supposé être à droite de la figure alors que le bas est à gauche, l'axe du dispositif étant supposé être horizontal et perpendiculaire à une des parois latérales de la piscine ;- Figure 1 is an axial sectional view of an embodiment of a submerged swimming pool device according to the invention equipped with a compartment containing a functional assembly, the top of the swimming pool being assumed to be on the right of the figure while the bottom is on the left, the axis of the device being assumed to be horizontal and perpendicular to one of the side walls of the pool;
- la figure 2 est une vue en coupe axiale du dispositif de la figure 1 équipé d'un cache de protection en l'absence d'ensemble fonctionnel. Sur la figure 1 , on voit que la paroi latérale 4 d'une piscine comporte un orifice cylindrique 5 ; dans l'orifice 5, on a disposé un boîtier 7 cylindrique avec interposition d'une garniture d'étanchéité 6.- Figure 2 is an axial sectional view of the device of Figure 1 equipped with a protective cover in the absence of a functional assembly. In Figure 1, we see that the side wall 4 of a swimming pool has a cylindrical orifice 5; in the orifice 5, a cylindrical housing 7 has been arranged with the interposition of a seal 6.
Pour réaliser la mise en place du boîtier 7, on pratique dans la paroi 4 de la piscine un carottage qui, ou bien débouche dans un couloir de visite préexistant, ou bien débouche dans une zone accessible par un forage externe, le but étant de sortir à l'extérieur de la piscine des câbles associés à un ensemble fonctionnel associé au dispositif. On positionne deux joints toriques 90, 91 sur la paroi externe du boîtier 7, aux deux extrémités de l'orifice 5 pour assurer le centrage du boîtier dans ledit orifice 5. Le joint 90 situé du côté piscine comporte deux trous, l'un au voisinage du point bas et l'autre au voisinage du point haut. On injecte une résine polymérisable par le trou inférieur pour constituer la garniture d'étanchéité 6 entre l'orifice de carottage 5 et le boîtier 7. Après polymérisation, on termine la face frontale de la garniture 6, du côté piscine, par mise en place d'un joint silicone 94.To carry out the installation of the housing 7, a coring is practiced in the wall 4 of the swimming pool which either opens into a preexisting inspection corridor, or opens into an area accessible by external drilling, the aim being to exit outside the pool of cables associated with a functional assembly associated with the device. Two O-rings 90, 91 are positioned on the external wall of the housing 7, at the two ends of the orifice 5 to ensure the centering of the housing in said orifice 5. The gasket 90 located on the swimming pool side has two holes, one at the near the low point and the other near the high point. A polymerizable resin is injected through the lower hole to form the seal 6 between the coring orifice 5 and the housing 7. After polymerization, the front face of the seal 6 is terminated, on the swimming pool side, by positioning a silicone seal 94.
Le boîtier 7 comporte un fond 7a ; son ouverture opposée à son fond est disposée au voisinage du carrelage 4a de la piscine ; son fond 7a est disposé au-delà de la face de la paroi 4, qui est opposée à l'intérieur de la piscine. Lorsqu' il y a un couloir de visite, qui entoure la piscine, le fond 7a fait donc légèrement saillie dans ledit couloir. Le fond 7a laisse passer, par un raccord étanche 23 , deux câbles 8, par exemple coaxiaux, qui, d'un côté, sont reliés à une centrale de contrôle non représentée et, de l'autre, se raccordent à l'ensemble fonctionnel mis en place dans un compartiment 3, que l'on peut fixer sur l'ouverture du boîtier 7. Dans l'exemple décrit sur la figure 1, l'ensemble fonctionnel comporte deux caméras 1 de type "CCD" disposées chacune en regard d'une lentille d 'observation 2 portée par un globe 17.The housing 7 has a bottom 7a; its opening opposite its bottom is arranged in the vicinity of the tiling 4a of the swimming pool; its bottom 7a is disposed beyond the face of the wall 4, which is opposite to the interior of the swimming pool. When there is a visit corridor, which surrounds the swimming pool, the bottom 7a therefore protrudes slightly in said corridor. The bottom 7a allows two cables 8, for example coaxial cables, which pass, on one side, to a control unit (not shown) and, on the other, to be connected to the functional unit, by a sealed connection 23 put in place in a compartment 3, which can be fixed on the opening of the housing 7. In the example described in FIG. 1, the functional unit comprises two cameras 1 of the "CCD" type, each disposed opposite one another. 'an observation lens 2 carried by a globe 17.
L'ouverture du boîtier 7 affleure le carrelage 4a de la paroi 4 de la piscine ; elle porte une collerette 9, fixée sur le boîtier 7 par quelques vis 10, par exemple six, qui sont régulièrement réparties sur le pourtour de l'ouverture du boîtier et dont une seule est représentée sur les figures 1 et 2. Cette collerette 9 recouvre la zone annulaire proche du pourtour de l'orifice 5 de façon à masquer les éventuels éclats du carrelage 4a résultant du carottage ainsi que le joint silicone 94.The opening of the housing 7 is flush with the tiling 4a of the wall 4 of the swimming pool; it carries a collar 9, fixed to the housing 7 by a few screws 10, for example six, which are regularly distributed around the periphery of the opening of the housing and only one of which is shown in FIGS. 1 and 2. This collar 9 covers the annular zone close to the periphery of the orifice 5 so as to mask any fragments of the tiling 4a resulting from the coring as well as the silicone seal 94.
A trois emplacements répartis sur le pourtour de son ouverture, le boîtier présente des renforcements d'épaisseur 11 destinés à recevoir des vis de fixation 12. Ces vis 12 sont destinées à la fixation sur le boîtier 7 de moyens de séparation interposés entre l'intérieur de la piscine et l'intérieur du boîtier 7 ; ces moyens de séparation sont constitués soit d'un compartiment étanche 3 contenant un ensemble fonctionnel (figure 1) soit d'un cache 13 (figure 2). Le compartiment 3 (ou le cache 13) est en appui sur le boîtier 7 au droit des renforcements d'épaisseur 11 ; il comporte sur sa paroi latérale trois dépressions permettant de loger les trois renforcements d'épaisseur 1 1 ; on oriente angulairement le moyen de séparation par rapport au boîtier en raison du fait que les renforcements d'épaisseur 1 1 ne sont pas angulairement équidistants. Le compartiment 3 (ou le cache 13) est décalé par rapport au pourtour de l'ouverture du boîtier 7, de façon à ménager une fente 14 pour le passage de l'eau de la piscine dans le boîtier 7.At three locations distributed around the periphery of its opening, the housing has thick reinforcements 11 intended to receive fixing screws 12. These screws 12 are intended for fixing on the housing 7 separation means interposed between the interior of the swimming pool and the interior of the housing 7; these means of separation are consisting either of a sealed compartment 3 containing a functional assembly (Figure 1) or of a cover 13 (Figure 2). The compartment 3 (or the cover 13) bears on the housing 7 in line with the thick reinforcements 11; it has on its side wall three depressions making it possible to house the three thickness reinforcements 1 1; the separation means are angularly oriented relative to the housing due to the fact that the reinforcements of thickness 1 1 are not angularly equidistant. The compartment 3 (or the cover 13) is offset with respect to the periphery of the opening of the housing 7, so as to provide a slot 14 for the passage of the water from the swimming pool into the housing 7.
Le compartiment 3 est constitué de deux parties fixées l'une à l'autre par des vis 15, avec interposition d'un joint d'étanchéité annulaire 16 : un globe 17 tourné vers la piscine et une cuvette 18 placée dans le boîtier 7. Le globe 17 est arrondi pour éviter toute blessure pour un nageur venant en contact avec ledit globe. Le globe 17 est moulé en fonte d'aluminium ; devant les caméras 1 de l'ensemble fonctionnel, il présente deux orifices circulaires où l'on a enchâssé deux lentilles 2 ; les lentilles 2 coopèrent avec les objectifs des deux caméras 1 pour constituer des "ensembles-objectifs" ; la bordure de chaque lentille 2 forme une collerette collée dans un embrèvement circulaire du globe 17. Les lentilles sont réalisées en un verre de dureté élevée pour éviter tout risque de détérioration ; le dessin des lentilles 2 permet d'adapter les caractéristiques optiques des "ensembles-objectifs" aux besoins du système. Le compartiment 3 porte une cloche 19, fixée de l'extérieur à la cuvette 18 au moyen de vis 20, avec interposition d'un joint d'étanchéité annulaire 21. La cloche 19 comporte un raccord étanche 22, et le fond du boîtier 7 comporte le raccord étanche 23. Entre ces deux raccords étanches 22 et 23 est disposée une gaine souple 24, étanche, qui sert de protection extérieure au câble 8 reliant la centrale de contrôle à l'ensemble fonctionnel logé dans le compartiment 3. La gaine 24 est, par exemple, enroulée en hélice contre la paroi intérieure du boîtier 7 ; elle a une longueur suffisante pour que le compartiment 3 puisse être amené sur le bord de la piscine tout en restant fixé au bout de la gaine 24. Les câbles 8 se terminent par un connecteur 92, qui est complémentaire d' un connecteur 93 porté par celle des faces du fond 18a de la cuvette 18, qui est en regard de la cloche 19. Le fond de la cuvette 18 porte une carte électronique 95 sur laquelle sont branchés les fils de sortie des caméras 1 de l'ensemble fonctionnel. La sortie de ladite carte électronique traverse de façon étanche le fond 18a qui, sur sa face externe, porte le connecteur 93. Le fond 18a porte, en outre, deux raccords à clapet 96 destinés à coopérer avec une tubulure d'alimentation en azote, d'une part, et avec une tubulure de mise à l'air libre, d'autre part. On peut ainsi, lorsque le compartiment 3 a été fermé par assemblage du globe 17 et de la cuvette 18, mettre l'intérieur du compartiment 3 sous azote sec pour éviter les oxydations, améliorer la durée de vie des caméras CCD et prévenir tout problème de formation de buée ; dès que les tubulures sont débranchées, les clapets des raccords 96 isolent l'intérieur du compartiment 3 vis-à-vis de l'extérieur. En même temps que les câbles 8, on enfile dans la gaine un fil en attente, par exemple un fil de nylon, qui, de façon connue, joue le rôle d'une "aiguille" destinée à permettre l' introduction d'un câble, complémentaire ou de remplacement, dans la gaine 24 sans qu'il soit nécessaire de déconnecter le raccord 23 et donc de vider la piscine : il suffit, en effet, d'accrocher le nouveau câble et une nouvelle "aiguille" au fil de nylon pré-existant, en arrière du fond 7a, de mettre hors d'eau l'ensemble (3, 19), de démonter la cloche 19, de déconnecter les connecteurs 92, 93, de tirer par l'extrémité ainsi dégagée de la gaine 24 le fil de nylon qui s'y trouve, jusqu'à apparition du nouveau câble et de la nouvelle "aiguille" , de jeter ledit fil de nylon pré-existant constituant 1' "aiguille" initiale, de raccorder le nouveau câble mis en place sur le connecteur 92, de ré-assembler la cloche 19 sur la cuvette 18, de redescendre l'ensemble (3 , 19) sous l 'eau et de le refixer par les vis 12 sur la face du boîtier 7. Dans le cas de la figure 2, la cloche 19 est fixée directement au cache 13 par les vis 20 avec interposition d'un joint d'étanchéité 21.The compartment 3 consists of two parts fixed to each other by screws 15, with the interposition of an annular seal 16: a globe 17 facing the swimming pool and a bowl 18 placed in the housing 7. The globe 17 is rounded to avoid any injury to a swimmer coming into contact with said globe. The globe 17 is molded from cast aluminum; in front of the cameras 1 of the functional assembly, it has two circular orifices in which two lenses 2 have been embedded; the lenses 2 cooperate with the objectives of the two cameras 1 to form "objective assemblies"; the edge of each lens 2 forms a collar stuck in a circular recess of the globe 17. The lenses are made of a glass of high hardness to avoid any risk of deterioration; the design of the lenses 2 makes it possible to adapt the optical characteristics of the "objective assemblies" to the needs of the system. The compartment 3 carries a bell 19, fixed from the outside to the bowl 18 by means of screws 20, with the interposition of an annular seal 21. The bell 19 comprises a tight connection 22, and the bottom of the housing 7 comprises the sealed connection 23. Between these two sealed connections 22 and 23 is arranged a flexible sheath 24, sealed, which serves as external protection for the cable 8 connecting the control unit to the functional unit housed in the compartment 3. The sheath 24 is, for example, wound helically against the inner wall of the housing 7; it has a sufficient length so that the compartment 3 can be brought to the edge of the swimming pool while remaining fixed to the end of the sheath 24. The cables 8 terminate in a connector 92, which is complementary to a connector 93 carried by that of the faces of the bottom 18a of the bowl 18, which is opposite the bell 19. The bottom of the bowl 18 carries an electronic card 95 to which the output wires of the cameras 1 of the functional unit are connected. The outlet of the said electronic card passes through the bottom 18a in a leaktight manner which, on its external face, carries the connector 93. The bottom 18a also carries two valve fittings 96 intended to cooperate with a nitrogen supply pipe, on the one hand, and with a vent pipe, on the other hand. It is thus possible, when compartment 3 has been closed by assembling the globe 17 and the bowl 18, put the interior of compartment 3 under dry nitrogen to avoid oxidation, improve the life of the CCD cameras and prevent any problem of fogging; as soon as the pipes are disconnected, the valves of the fittings 96 isolate the inside of the compartment 3 from the outside. At the same time as the cables 8, a waiting thread is threaded into the sheath, for example a nylon thread, which, in known manner, acts as a "needle" intended to allow the introduction of a cable , complementary or replacement, in the sheath 24 without the need to disconnect the connector 23 and therefore empty the pool: it suffices, in fact, to hook the new cable and a new "needle" to the nylon thread pre-existing, behind the bottom 7a, to put the assembly out of water (3, 19), to dismount the bell 19, to disconnect the connectors 92, 93, to pull by the end thus released from the sheath 24 the nylon thread therein, until the appearance of the new cable and the new "needle", to throw said pre-existing nylon thread constituting the initial "needle", to connect the new cable put in place on the connector 92, reassemble the bell 19 on the bowl 18, lower the assembly (3, 19) under water and l e reattach by the screws 12 on the face of the housing 7. In the case of FIG. 2, the bell 19 is fixed directly to the cover 13 by the screws 20 with the interposition of a seal 21.
Le dispositif immergé pour piscine selon l'invention peut être mis en place directement dans la configuration de la figure 1 , ou bien il peut être provisoirement mis en place dans la configuration de la figure 2. Dans ce dernier cas (figure 2), le cache 13 assure là protection des éléments inclus dans le boîtier 7. Lorsqu'un ensemble fonctionnel doit être installé dans le dispositif, il est inutile de vider partiellement ou totalement la piscine. Les vis 12 sont enlevées dans l'eau, le cache 13 est enlevé et il entraîne la cloche 19 et la gaine 24. Le cache et la cloche sont remontés sur le bord de la piscine. Les vis 20 sont enlevées ; le compartiment 3 est substitué au cache 13, les connexions électriques sont réalisées grâce aux connecteurs 92, 93 et les vis 20 sont remises en place. Le compartiment 3 équipé de sa cloche 19 est alors mis en place dans le boîtier 7 en enroulant au fur et à mesure la gaine 24. Les vis 12 sont remises en place sous l'eau pour fixer le compartiment 3 sur le boîtier 7 (figure 1 ). Pendant toutes ces opérations, aussi bien qu'avant et après, l'eau de la piscine remplit le boîtier 7. En raison de la présence de la fente 14, il n'y a aucune difficulté pour enlever ou mettre en place le cache 13 ou le compartiment 3.The submerged swimming pool device according to the invention can be installed directly in the configuration of FIG. 1, or it can be temporarily installed in the configuration of FIG. 2. In the latter case (FIG. 2), the cache 13 ensures there protection of the elements included in the box 7. When a functional unit must be installed in the device, it is useless to partially or completely empty the pool. The screws 12 are removed in the water, the cover 13 is removed and it drives the bell 19 and the sheath 24. The cover and the bell are raised on the edge of the swimming pool. The screws 20 are removed; compartment 3 is substituted for cover 13, the electrical connections are made using connectors 92, 93 and the screws 20 are replaced. The compartment 3 equipped with its bell 19 is then put in place in the housing 7 by winding the sheath 24 progressively. The screws 12 are replaced under water to fix the compartment 3 on the housing 7 (FIG. 1). During all these operations, as well as before and after, the water from the swimming pool fills the housing 7. Due to the presence of the slot 14, there is no difficulty in removing or putting the cover 13 in place. or compartment 3.
Lorsque la piscine doit être vidée et nettoyée, par exemple avec des produits acides, il est préférable, sinon indispensable, pour la sauvegarde des lentilles optiques 2 du globe 17, de remplacer le compartiment 3 par un cache 13. La disposition de la gaine 24 permet de conserver les câbles et connexions électriques à l'air ambiant, ce qui permet d'utiliser des composants électriques classiques et non-étanches et de s'affranchir de la nécessité d'utiliser un presse-étoupe pour les passages de câble au niveau du fond 7a. De plus, le câble étant à l'air libre dans la gaine 24, il peut être remplacé sans difficulté, grâce au fil de nylon mis en attente dans la gaine.When the swimming pool must be emptied and cleaned, for example with acid products, it is preferable, if not essential, for the safeguarding of the optical lenses 2 of the globe 17, to replace the compartment 3 by a cover 13. The arrangement of the sheath 24 keeps electrical cables and connections in the ambient air, which allows the use of conventional and non-watertight electrical components and eliminates the need to use a cable gland for cable passages at level from the bottom 7a. In addition, the cable being in the open air in the sheath 24, it can be replaced without difficulty, thanks to the nylon thread put on hold in the sheath.
Le dispositif immergé selon l' invention peut être équipé de différents ensembles fonctionnels. C'est ainsi que le compartiment 3 peut recevoir, par exemple, un ou plusieurs projecteurs d'éclairage de la piscine, des caméras pour la surveillance des baigneurs en vue de détecter le risque de noyade, des caméras pour le fi Image d'épreuves sportives ou de compétitions de water-polo, des capteurs pour effectuer une télémétrie par laser, un sonar de mesures, ou des appareils de sonorisation pour les épreuves de natation synchronisée, cette énumération n'étant pas limitative. Le dispositif immergé selon l' invention présente de nombreux avantages parmi lesquels peuvent être soulignés :The submerged device according to the invention can be equipped with different functional assemblies. This is how compartment 3 can receive, for example, one or more pool lighting projectors, cameras for monitoring swimmers with a view to detecting the risk of drowning, cameras for fi sports or water polo competitions, sensors for laser telemetry, measurement sonar, or sound devices for synchronized swimming events, this list is not exhaustive. The submerged device according to the invention has many advantages, among which can be highlighted:
- l'absence de gêne pour la natation en raison de la forme arrondie du globe 17 ou de la forme plate du cache 13 ; - la facilité d'installation par carottage et scellement étanche dans le mur de piscine ;- the absence of discomfort for swimming due to the rounded shape of the globe 17 or the flat shape of the cover 13; - ease of installation by coring and waterproof sealing in the pool wall;
- la sécurité contre les éclats assurée par la collerette 9 ;- the security against splinters provided by the collar 9;
- la facilité d'intervention hors d'eau en raison de la gaine 24 disposée à l'intérieur du boîtier 7, ce qui permet de réparer ou interchanger rapidement l'ensemble fonctionnel contenu dans le compartiment 3 ;- The ease of intervention out of water due to the sheath 24 disposed inside the housing 7, which allows to quickly repair or interchange the functional assembly contained in the compartment 3;
- l'absence de problèmes d'échauffement de l'ensemble fonctionnel car l'eau circule autour du compartiment 3 dans le boîtier 7 ; - l'absence de stagnation de l'eau dans le boîtier 7 en raison de la présence de la fente 14 de passage de l'eau sur la majeure partie du pourtour du cache 13 ou du compartiment 3 et en raison des dimensions suffisantes de la fente 14, ce qui évite tout problème de pollution de la piscine dû à des eaux mortes. - The absence of heating problems of the functional unit because the water circulates around compartment 3 in the housing 7; - The absence of stagnation of water in the housing 7 due to the presence of the slot 14 for the passage of water over the major part of the periphery of the cover 13 or of the compartment 3 and due to the sufficient dimensions of the slot 14, which avoids any problem of pollution of the swimming pool due to dead water.
