Description
La présente invention se rapporte à un véhicule nautique submersible, comprenant essentiellement un habitacle à capot amovible et étanche à l'eau, permettant à une ou deux personnes d'embarquer, et de moyens de propulsion permettant le déplacement dudit véhicule.The present invention relates to a submersible nautical vehicle, essentially comprising a cabin with a removable and waterproof hood, allowing one or two people to board, and propulsion means allowing the displacement of said vehicle.
Diverses embarcations ont été développées dans l'état de la technique en vue de proposer des véhicules nautiques permettant d'agrémenter les loisirs à la fois sur la surface de l'eau mais également en dessous de celle-ci.Various boats have been developed in the state of the art with a view to proposing nautical vehicles to enhance leisure in both on the surface of the water but also below of it.
Le document FR-A-2463049 décrit un engin flottant sur l'eau qui est rendu insubmersible par des moyens de stabilisation e de flottaison. Ce véhicule est disposé de manière permanente à la surface de l'eau et en contact direct avec l'air libre. Il comprend toutefois un hublot d'observation immergé dans l'eau pour permettre une vision sous-marine. Cependant, le champ de vision en profondeur de ce type de véhicule reste limité.Document FR-A-2463049 describes a machine floating on water which is made unsinkable by means of stabilization and flotation. This vehicle is permanently disposed on the surface of the water and direct contact with the open air. It does however include a observation window immersed in water to allow a underwater vision. However, the field of vision in depth of this type of vehicle remains limited.
Le document FR-A-2703652 décrit un engin nautique complètement submersible dans l'eau jusqu'à des profondeurs relativement importantes et qui permet un déplacement aisé aussi bien en surface qu'en plongée. L'embarcation décrite se présente sous la forme d'un catamaran "ouvert", c'est-à-dire dépourvu d'un habitacle étanche à l'eau, qui sert de moyen d'embarcation et de déplacement. Dans ce cas, uniquement des personnes équipées d'une combinaison de plongée pourront se déplacer à l'aide de ce genre de véhicule.Document FR-A-2703652 describes a machine nautical completely submersible in water up to relatively large depths and which allows a easy movement both on the surface and in diving. The boat described is in the form of a "open" catamaran, that is to say without a cockpit waterproof, which serves as a means of boat and displacement. In this case, only persons equipped of a wetsuit can be moved using of this kind of vehicle.
On a également proposé des engins nautiques partiellement submersibles à une profondeur réduite et dans lesquels il n'est pas nécessaire de prévoir un équipement de plongée pour les utilisateurs. En particulier, le document EP-A-165192 propose un véhicule marin semi ou partiellement submersible, qui comprend des moyens de propulsion fonctionnant aussi bien en surface qu'en semi-submersion et équipé d'un habitacle en forme de bulle transparente. La hauteur de l'habitacle reste supérieure à la profondeur de plongée de sorte que seule la partie inférieure de cet habitacle est immergée lors de l'utilisation du véhicule en plongée. En outre, des équipements de contrôle et de sécurité sont intégrés à ce type de véhicule afin d'éviter tout risque d'une immersion complète de l'habitacle.We also proposed nautical devices partially submersible to a reduced depth and in which it is not necessary to provide an equipment diving for users. In particular, the document EP-A-165192 proposes a semi or partially submersible, which includes means for propulsion working both on the surface and in semi-submersion and fitted with a bubble-shaped interior transparent. The height of the passenger compartment remains greater than the diving depth so that only the part lower part of this passenger compartment is submerged during using the vehicle while diving. In addition, control and safety equipment are integrated into this type of vehicle to avoid any risk of immersion complete interior.
Le document FR-A-2607101 décrit un appareil semi-submersible permettant l'observation sous-marine et comprenant un habitacle submergeable. Cet appareil comprend également des flotteurs qui peuvent être reliés à l'habitacle à l'aide de bras mécaniques articulés. L'immersion de l'habitacle se fera par son poids propre, qui lui permet de s'enfoncer spontanément dans l'eau. L'émersion s'effectuera par l'intermédiaire d'un treuil qui agit sur un câble qui relie l'habitacle aux flotteurs. Ce treuil est simplement actionné depuis l'intérieur de l'habitacle. Il convient de noter qu'un défaut mécanique lors du fonctionnement du treuil par exemple, pourrait rendre l'utilisation d'un tel dispositif risquée ou peu fiable.Document FR-A-2607101 describes an apparatus semi-submersible allowing underwater observation and including a submersible cockpit. This device includes also floats which can be connected to the passenger compartment using articulated mechanical arms. The immersion of the passenger compartment will be by its own weight, which allows it to sink spontaneously into the water. The emersion will be carried out by means of a winch which acts on a cable which connects the passenger compartment to the floats. This winch is simply operated from inside the passenger compartment. It should be noted that a mechanical defect during the operation of the winch for example, could make the use of such a device risky or little reliable.
La présente invention vise à proposer un véhicule nautique submersible qui ne présente pas les inconvénients des véhicules de l'état de la technique.The present invention aims to provide a submersible nautical vehicle that does not have the disadvantages of prior art vehicles.
Plus précisément, la présente invention vise à proposer un véhicule nautique qui permet d'être utilisé aisément sans nécessité d'un apprentissage ou d'un entraínement approfondi de la part des utilisateurs.More specifically, the present invention aims to offer a nautical vehicle that allows it to be used easily without the need for learning or extensive training from users.
La présente invention vise principalement à proposer un véhicule nautique submersible qui présente des conditions de sécurité et de fiabilité maximales tout en maintenant le coût de production relativement réduit.The main object of the present invention is to offer a submersible nautical vehicle that has maximum safety and reliability conditions while now the production cost relatively reduced.
La présente invention se rapporte à un véhicule nautique submersible comprenant un habitacle et des ballasts, caractérisé en ce qu'il comprend également des moyens de flottaison ou flotteurs reliés auxdits ballasts à l'aide de deux bras mécaniques articulés et équipés de moyens pneumatiques permettant le lien entre lesdits flotteurs et lesdits ballasts.The present invention relates to a submersible water vehicle comprising a passenger compartment and ballasts, characterized in that it also includes flotation means or floats connected to said ballasts using two articulated mechanical arms and equipped with pneumatic means allowing the link between said floats and said ballasts.
De préférence, des moyens de récupération de l'air emprisonné dans les flotteurs sont prévus pour le renvoyer vers les ballasts, par exemple par l'utilisation d'une pompe.Preferably, means for recovering the air trapped in the floats is intended for the refer to ballasts, for example by use of a pump.
De manière avantageuse, le volume des flotteurs est identique à celui des ballasts. Ces flotteurs se présentent sous la forme de ballons possédant une partie inférieure rigide et une partie souple. Advantageously, the volume of floats is identical to that of ballasts. These floats are in the form of balloons having a part rigid lower part and a flexible part.
Des moyens de ventilation du véhicule nautique sont en outre prévus. Ceux-ci se présentent sous la forme de deux tubes schnorkel dont les parties supérieures sont solidaires des flotteurs avec une connexion à l'air libre ainsi qu'une pompe secondaire permettant une arrivée d'air et une évacuation de CO2.Means of ventilation of the nautical vehicle are also provided. These are in the form of two schnorkel tubes, the upper parts of which are integral with the floats with a connection to the open air as well as a secondary pump allowing an air intake and a CO 2 evacuation.
On a également prévu des moyens de propulsion soit mécaniques, soit électriques, dudit véhicule.There are also means of propulsion either mechanical or electrical, of said vehicle.
De manière particulièrement avantageuse, ce type de véhicule permet de réaliser une plongée permettant l'observation de la faune et de la flore sous-marines à faible profondeur dans des conditions de sécurités optimales.Particularly advantageously, this type of vehicle allows for a dive allowing observation of underwater flora and fauna in shallow depth under safe conditions optimal.
Les figures 1 à 5 représentent différentes vues d'une forme d'exécution préférée d'un véhicule nautique submersible selon la présente invention.Figures 1 to 5 show different views of a preferred embodiment of a vehicle nautical submersible according to the present invention.
Le véhicule nautique désigné par le repère de
référence général 1 comprend un habitacle 2 pourvu d'un
capot amovible 3 muni d'un hublot 31 permettant
l'embarcation d'un ou plusieurs passagers lorsque le
véhicule est en surface (figures 1a, 2a et 3a).The nautical vehicle designated by the
Ce hublot est bien entendu réalisé en un matériau transparent et présente la plus grande surface possible de manière à permettre une observation du milieu sous-marin.This window is of course made in one transparent material and has the largest area possible so as to allow observation of the environment submarine.
Après l'embarquement des passagers, le capot est ensuite refermé de manière étanche à l'aide de moyens de verrouillage adéquats afin de permettre l'immersion du véhicule (figures 1b, 2b et 3b).After passenger boarding, the hood is then tightly closed using means adequate locking to allow immersion of the vehicle (Figures 1b, 2b and 3b).
Ce véhicule comprend, au sein de l'habitacle,
au moins deux ballasts 4 et 5 qui sont de préférence
disposés de chaque côté de celui-ci afin de garantir une
meilleure répartition des masses. De préférence, un ballast
sera situé à l'avant tandis que l'autre sera situé à
l'arrière.This vehicle includes, within the passenger compartment,
at least two
Le véhicule comprend également au moins deux
flotteurs 6 et 7 fixés au véhicule par l'intermédiaire de
deux arbres mécaniques pivotables 8 et 9. En outre, ces
arbres mécaniques pivotables comprennent également un moyen
pneumatique permettant un lien entre les ballasts 4 et 5 et
les flotteurs 6 et 7. Le volume desdits flotteurs 6 et 7
doit être identique à celui des ballasts 4 et 5 afin de
permettre un échange gazeux sans entraíner de compression
ou de dilatation. Leur forme sera également appropriée afin
de ne pas freiner la progression du sous-marin. De
préférence, les flotteurs se présentent sous la forme de
ballons présentant une partie rigide inférieure dans
laquelle est emboítée une partie souple et qui permet de
les gonfler lors de l'immersion du véhicule.The vehicle also includes at least two
En situation d'émersion, les deux flotteurs 6
et 7 sont totalement dégonflés et les arbres mécaniques 8
et 9 sont disposés de manière essentiellement horizontale
le long du véhicule nautique 1. Lors de l'opération de
plongée, obtenue par inondation des ballasts 4 et 5, l'air
est chassé de ceux-ci vers les flotteurs 6 et 7 par
l'intermédiaire des moyens pneumatiques, ce qui permet de
gonfler les deux flotteurs 6 et 7. En position d'immersion
maximale, on observe que les bras mécaniques 8 et 9 sont
disposés de manière essentiellement verticale par rapport
au plan de la surface de l'eau, maintenant les deux
flotteurs 6 et 7 gonflés en surface.In an emersion situation, the two
De manière particulièrement avantageuse, on observe que ces différentes éléments (ballasts, flotteurs et bras mécaniques équipés de moyens pneumatiques) assurent de manière simultanée plusieurs fonctions, et permettent en particulier de:
- récupérer l'air chassé des ballasts 4 et 5 lors de la
plongée dans les
flotteurs 6 et 7, - récupérer cet air emprisonné dans les
flotteurs 6+ et 7 en le renvoyant vers les ballasts 4 et 5 pour réaliser l'opération d'émersion duvéhicule 1, - limiter la profondeur maximale de plongée dudit
habitacle 2 à la longueur des arbres mécaniques 8 et 9, - maintenir une stabilité dudit habitacle en maintenant l'assiette de celui-ci en position essentiellement horizontale, et
- indiquer la présence du véhicule nautique immergé en surface.
- recover the air expelled from
ballasts 4 and 5 when diving intofloats - recover this air trapped in the
floats 6+ and 7 by sending it back to theballasts 4 and 5 to carry out the emersion operation of thevehicle 1, - limit the maximum diving depth of said
passenger compartment 2 to the length of themechanical shafts 8 and 9, - maintain stability of said passenger compartment by maintaining its trim in an essentially horizontal position, and
- indicate the presence of the water vehicle submerged on the surface.
Il convient également de prévoir une
ventilation adéquate de l'habitacle du véhicule, en
particulier en situation d'immersion. De préférence, celle-ci
devra s'enclencher de manière automatique dès fermeture
du capot 3.There should also be a
adequate ventilation of the vehicle interior,
particularly in immersion situations. Preferably, this
will have to start automatically when closing
De manière particulièrement avantageuse, on a envisagé de prévoir l'utilisation de tubes schnorkel qui permettent un lien entre l'habitacle et la surface en vue de permettre la respiration des passagers embarqués dans le véhicule nautique. De préférence, un premier tube schnorkel est disposé dans le bras mécanique pivotable afin de permettre l'arrivée de l'air extérieur à l'aide d'une main courante solidarisée au flotteur et qui permet de ce fait d'être constamment à l'air libre. L'évacuation s'effectuera par un second tube schnorkel disposé le long du second bras mécanique vers la surface. De préférence, l'aspiration sera effectuée à l'aide de moyens adéquats (pompe) qui seront disposés sous les sièges. On observe ainsi la disparition de la buée pouvant être générée par la respiration des passagers à l'intérieur de l'habitacle.Particularly advantageously, we have considered providing for the use of schnorkel tubes which allow a link between the passenger compartment and the surface in view to allow the breathing of the passengers embarked in the nautical vehicle. Preferably, a first schnorkel tube is arranged in the pivotable mechanical arm in order to allow the outside air to come in using one hand current secured to the float and which therefore allows to be constantly in the open air. Evacuation will take place by a second schnorkel tube placed along the second arm mechanical to the surface. Preferably, the suction will be carried out using suitable means (pump) which will be arranged under the seats. We thus observe the disappearance fogging that can be generated by the breathing of passengers inside the passenger compartment.
Une autre alternative pour prévoir la ventilation pourrait être réalisée en embarquant de l'oxygène comprimé, par exemple. Dans ce cas, il est nécessaire de prévoir l'évacuation du CO2.Another alternative to provide ventilation could be achieved by taking on compressed oxygen, for example. In this case, it is necessary to plan the evacuation of CO 2 .
Des moyens de propulsion dudit véhicule
nautique sont prévus, qui peuvent être des moyens
mécaniques ou électriques. Ceux-ci seront adaptés
précisément audit véhicule nautique afin d'éviter tout
risque, d'électrocution, d'incendie, d'asphyxie ou autre.
Ces moyens de propulsions sont reliés à une hélice 11 et à
un gouvernail 12 afin de permettre le déplacement dudit
véhicule nautique en surface ou sous l'eau. Means of propulsion of said vehicle
nautical are planned, which can be
mechanical or electrical. These will be adapted
precisely to this nautical vehicle in order to avoid any
risk of electric shock, fire, suffocation or other.
These propulsion means are connected to a
Afin d'augmenter la stabilité dudit véhicule, on peut également envisager d'abaisser son centre de gravité en prévoyant une quille sous la coque du véhicule.In order to increase the stability of said vehicle, we can also consider lowering its center of gravity by providing a keel under the hull of the vehicle.
Les différents éléments du véhicule seront réalisés en des matériaux composites qui permettent le moulage. Ceci permet d'allier les avantages de résistance importante pour un coût de réalisation raisonnable, et permet en outre d'éviter tout problème de corrosion. Les articulations des bras mécaniques seront réalisées en téflon, ce qui garantira une durée de vie importante ainsi qu'une bonne autolubrification.The different elements of the vehicle will made of composite materials which allow the molding. This combines the advantages of resistance important for a reasonable cost of realization, and furthermore, it avoids any corrosion problem. The mechanical arm joints will be made in teflon, which will guarantee a long service life as well than good self-lubrication.
De manière particulièrement avantageuse, on peut réaliser un véhicule nautique submersible tel que décrit précédemment en prévoyant certains aménagements complémentaires, tels qu'un habitacle réalisé de manière indépendante qui pourra remonter même si le véhicule est inondé. Il est également important de prévoir que les pompes d'immersion s'arrêtent automatiquement lorsque le sous-marin atteint sa profondeur maximale.Particularly advantageously, we can realize a submersible nautical vehicle such as described above with some improvements complementary, such as a passenger compartment constructed independent which can be reassembled even if the vehicle is flooded. It is also important to provide that immersion pumps stop automatically when the submarine reaches its maximum depth.
Une communication phonique permanente avec l'extérieur devrait être prévue grâce à l'installation à bord d'un haut-parleur relié à une radio.Permanent voice communication with the exterior should be provided thanks to the installation at on a loudspeaker connected to a radio.
Il convient également de prévoir des signaux d'avertissement sonores ou visuels dans le cas où la quantité de CO2 devient trop importante dans l'habitacle. Dans ce cas, une pompe de vidange des ballasts devra s'actionner, permettant une remontée automatique et rapide.It is also advisable to provide audible or visual warning signals in the event that the quantity of CO 2 becomes too large in the passenger compartment. In this case, a ballast drain pump must be activated, allowing automatic and rapid ascent.
Un système de vérification de l'étanchéité devra être prévu avant de permettre une plongée. De même, on peut également prévoir de manière particulièrement avantageuse un lest largable mécaniquement afin de permettre une remontée rapide en cas de problème ou incident.A tightness verification system must be planned before allowing a dive. Likewise, one can also provide in a particularly advantageous a mechanically releasable ballast in order to allow rapid ascent in the event of a problem or incident.
