Description

Périscope flottant notamment pour un engin sous-marin Periscope floating especially for an underwater vehicle
La présente invention concerne un périscope flottant notamment pour un engin sous-marin.The present invention relates to a floating periscope, in particular for an underwater vehicle.
On connaît déjà dans l'état de la technique, des périscopes flottants notamment pour engin sous-marin de ce type, qui comportent un container flottant présentant une forme allongée, dont une extrémité est adaptée pour faire saillie au-dessus du niveau de l'eau et qui comporte des moyens de prise de vue de l'environnement, portés par une plateforme stabilisée, elle-même portée par des moyens de suspension à la cardan. Un tel système est connu par exemple du document US 7,279,675.Floating periscopes, particularly for underwater vehicles of this type, which comprise a floating container having an elongate shape, one end of which is adapted to protrude above the level of the vessel, are already known in the state of the art. water and which comprises means for shooting the environment, carried by a stabilized platform, itself carried by cardan suspension means. Such a system is known for example from US 7,279,675.
De tels systèmes ont été développés pour améliorer la discrétion des engins sous-marins et en particulier des sous-marins proprement dits.Such systems have been developed to improve the discretion of underwater vehicles and in particular submarines themselves.
En effet, de tels périscopes flottants peuvent être utilisés en remplacement ou en complément des périscopes de massif de ceux-ci, qui nécessitent d'être hissés au-dessus de la surface de l'eau et à partir du sous-marin, alors que celui- ci est à immersion périscopique et à vitesse réduite.Indeed, such floating periscopes can be used as a replacement for or in addition to the periscopes of the massif of these, which need to be hoisted above the surface of the water and from the submarine, while this is periscopic immersion and at reduced speed.
On conçoit alors que cette situation se traduit par le fait que le sous-marin est relativement vulnérable. En effet, il est en immersion peu profonde et même si le sous-marin se déplace à faible vitesse, le périscope laisse une traînée visible à la surface de l'eau.It is understandable then that this situation results in the fact that the submarine is relatively vulnerable. Indeed, it is in shallow immersion and even if the submarine moves at low speed, the periscope leaves a visible trail on the surface of the water.
Par rapport à ces périscopes hissés à partir du massif du sous-marin, les périscopes flottants présentent un certain nombre d'avantages, dans la mesure où l'immersion du sous-marin a peu d'importance et où un périscope flottant ne laisse pas de traînée visible. Cependant, dans ces périscopes flottants tels qu'illustrés par le document antérieur, se pose le problème de la stabilité des moyens de prise de vue.Compared to these periscopes hoisted from the submarine, floating periscopes have a number of advantages, insofar as submarine immersion is of little importance and where a floating periscope does not leave visible trail. However, in these floating periscopes as illustrated by the previous document, there is the problem of the stability of the shooting means.
En effet, le périscope est soumis à différents mouvements et en particulier aux mouvements des vagues, etc ..., de sorte qu'il est nécessaire d'utiliser des moyens de stabilisation des moyens de prise de vue. Ces moyens de stabilisation peuvent par exemple être des moyens de stabilisation gyroscopiques associés à la plateforme de support des moyens de prise de vue, ou encore des moyens de stabilisation informatiques par traitement des images délivrées par ces moyens de prise de vue. On conçoit cependant que ces différents moyens sont relativement complexes et coûteux à mettre en œuvre.Indeed, the periscope is subject to different movements and in particular wave movements, etc ..., so it is necessary to use stabilization means of the shooting means. These stabilization means may for example be gyroscopic stabilization means associated with the support platform of the shooting means, or else computer stabilization means by processing the images delivered by these shooting means. However, it is conceivable that these different means are relatively complex and expensive to implement.
Le but de l'invention est donc de résoudre ces problèmes.The object of the invention is therefore to solve these problems.
A cet effet, l'invention a pour objet un périscope flottant notamment pour engin sous-marin, du type comportant un container flottant présentant une forme allongée dont une extrémité est adaptée pour faire saillie au-dessus du niveau de l'eau et comporte des moyens de prise de vue de l'environnement, portés par une plateforme stabilisée elle-même portée par des moyens de suspension à la cardan, caractérisé en ce que la plateforme stabilisée est associée à au moins une tige de stabilisation s'étendant selon l'axe longitudinal du container et dont une extrémité est associée à la plateforme et dont l'autre extrémité est associée à des moyens formant masselotte de stabilisation en position.For this purpose, the subject of the invention is a floating periscope, in particular for underwater vehicles, of the type comprising a floating container having an elongate shape, one end of which is adapted to protrude above the water level and comprises means of shooting the environment, carried by a stabilized platform itself carried by cardan suspension means, characterized in that the stabilized platform is associated with at least one stabilizing rod extending according to the longitudinal axis of the container and one end of which is associated with the platform and the other end of which is associated with stabilizing weight means in position.
Selon d'autres aspects de l'invention, le périscope flottant comprend l'une ou plusieurs des caractéristiques suivantes : - l'extrémité du container adaptée pour faire saillie au-dessus du niveau de l'eau et comportant les moyens de prise de vue de l'environnement, comporte un hublot transparent,According to other aspects of the invention, the floating periscope comprises one or more of the following characteristics: the end of the container adapted to protrude above the level of the water and comprising the means for shooting of the environment, has a transparent porthole,
- la plateforme de stabilisation est montée articulée dans un cadre autour d'un premier axe, et ce cadre est articulé sur le reste du container autour d'un second axe perpendiculaire au premier,the stabilization platform is articulated in a frame around a first axis, and this frame is articulated on the rest of the container around a second axis perpendicular to the first,
- le container est cylindrique,the container is cylindrical,
- les moyens de prise de vue comprennent des moyens formant caméras,the shooting means comprise means forming cameras,
- il comporte des moyens de transmission d'informations à destination de l'engin sous-marin, - les moyens de transmission d'informations sont des moyens filaires,it comprises means for transmitting information to the underwater vehicle, the information transmission means are wire means,
- il comporte des moyens d'accélération de sa vitesse de remontée vers la surface après son largage, afin de l'amener à sauter au-dessus de la surface de l'eau et des vagues,it comprises means of accelerating its speed of return to the surface after its release, in order to cause it to jump over the surface of the water and the waves,
- l'engin sous-marin est un sous-marin proprement dit, - l'engin sous-marin est un drone sous-marin, et- the underwater vehicle is a submarine proper, - the underwater vehicle is a submarine drone, and
- l'engin sous-marin est un équipement sous-marin mis à la disposition d'un plongeur. L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :- the underwater vehicle is an underwater equipment made available to a diver. The invention will be better understood with the aid of the following description given solely by way of example and with reference to the appended drawings, in which:
- la figure 1 illustre le principe d'utilisation d'un périscope flottant selon l'invention,FIG. 1 illustrates the principle of using a floating periscope according to the invention,
- la figure 2 représente une vue de côté d'un tel périscope,FIG. 2 represents a side view of such a periscope,
- la figure 3 représente une vue en perspective de la structure interne d'un tel périscope,FIG. 3 represents a perspective view of the internal structure of such a periscope,
- la figure 4 représente une vue de dessus de cette structure, et - la figure 5 représente une vue en coupe d'une telle structure.- Figure 4 shows a top view of this structure, and - Figure 5 shows a sectional view of such a structure.
Comme cela a été indiqué précédemment, un périscope flottant tel que celui désigné par la référence générale 1 sur ces figures, peut être déployé par exemple à partir d'un engin sous-marin désigné par la référence générale 2 sur la figure 1 , cet engin sous-marin étant par exemple un sous-marin proprement dit. Un tel périscope flottant peut par exemple être utilisé pour compléter ou remplacer l'utilisation d'un périscope de massif du sous-marin comme le périscope désigné par la référence générale 3 sur la figure 1 , et permet alors d'observer l'environnement de celui-ci, et de détecter par exemple des navires de surface, comme le bâtiment désigné par la référence générale 4 sur cette figure 1. Comme cela est illustré sur la figure 2, le périscope selon l'invention comporte un container flottant désigné par la référence générale 5 sur cette figure, ce container flottant présentant une forme allongée, dont une extrémité est adaptée pour faire saillie au-dessus du niveau de l'eau et comporte des moyens 6 de prise de vue de l'environnement, portés par une plateforme stabilisée elle- même supportée par des moyens de suspension à la cardan.As previously indicated, a floating periscope such as that designated by the general reference 1 in these figures, can be deployed for example from an underwater vehicle designated by the general reference 2 in Figure 1, this machine submarine being for example a submarine proper. Such a floating periscope may for example be used to complete or replace the use of a sub-massif periscope such as the periscope designated by the general reference 3 in FIG. 1, and then allows the environment of the submarine to be observed. this, and detect for example surface vessels, such as the building designated by the general reference 4 in this Figure 1. As shown in Figure 2, the periscope according to the invention comprises a floating container designated by the general reference 5 in this figure, this floating container having an elongated shape, one end of which is adapted to project above the water level and comprises means 6 for taking the environment, carried by a platform stabilized itself supported by cardan suspension means.
Dans l'exemple illustré, les moyens de prise de vue 6 sont par exemple formés par des moyens formant caméras et sont disposés sous un dôme transparent 7 de l'extrémité correspondante du container 5.In the example illustrated, the shooting means 6 are for example formed by camera means and are arranged under a transparent dome 7 of the corresponding end of the container 5.
Ce container peut par exemple être relié par des moyens de transmission d'informations tels que par exemple des moyens filaires, à destination de l'engin sous-marin.This container may for example be connected by information transmission means such as for example wired means to the underwater vehicle.
En fait et comme cela est illustré sur les figures 3, 4 et 5, les moyens 6 de prise de vue de l'environnement sont portés par une plateforme stabilisée désignée par la référence générale 8 sur ces figures, associées à au moins une tige de stabilisation désignée par la référence générale 9, s'étendant selon l'axe longitudinal du container 5, celui-ci étant par exemple cylindrique, et dont une extrémité est associée à la plateforme et dont l'autre extrémité est associée à des moyens formant masselotte de stabilisation en position, désignés par la référence générale 10.In fact and as illustrated in FIGS. 3, 4 and 5, the means 6 for shooting the environment are carried by a stabilized platform designated by the general reference 8 in these figures, associated with at least one stabilizing rod designated by the general reference 9, extending along the longitudinal axis of the container 5, the latter being for example cylindrical, and one end of which is associated with the platform and whose other end is associated with means for forming a stabilization weight in position, designated by the general reference 10.
En fait et comme cela est illustré, la plateforme de stabilisation 8 est montée articulée dans un cadre 11 selon un premier axe A-A, ce cadre 1 1 étant lui-même articulé sur le reste du container autour d'un second axe B-B perpendiculaire au premier.In fact and as illustrated, the stabilization platform 8 is articulated in a frame 11 along a first axis AA, this frame 1 1 itself being hinged to the rest of the container around a second axis BB perpendicular to the first .
Comme cela est illustré sur ces figures, la plateforme et le cadre sont articulés l'une par rapport à l'autre, et par rapport au reste de la structure du périscope par l'intermédiaire de portions de tige d'articulation dont l'une est par exemple désignée par la référence générale 12 sur la figure 4. II va de soi bien entendu qu'un tel périscope flottant peut être utilisé à partir d'un engin sous-marin qui peut se présenter sous la forme d'un sous-marin proprement dit, d'un drone sous-marin ou encore d'un équipement sous-marin mis à disposition par exemple de plongeurs qui peuvent ainsi rester discrets dans le contexte évoqué dans le préambule de la présente description. Par ailleurs, le container peut également être équipé de moyens d'accélération de sa vitesse de remontée vers la surface après son largage, afin de l'amener à sauter au-dessus de la surface de l'eau et notamment au-dessus des vagues, et permettre ainsi d'améliorer l'observation de l'environnement.As illustrated in these figures, the platform and the frame are articulated with respect to each other, and with respect to the remainder of the periscope structure via hinge pin portions, one of which is for example designated by the general reference 12 in Figure 4. It goes without saying of course that such a floating periscope can be used from an underwater vehicle that can be in the form of a subset. marine proper, a submarine drone or underwater equipment provided for example by divers who can thus remain discreet in the context mentioned in the preamble of this description. Furthermore, the container may also be equipped with means of accelerating its speed of recovery to the surface after its release, to cause it to jump over the surface of the water and especially above the waves , and thus to improve the observation of the environment.
En effet, des moyens mécaniques, pyrotechniques, hydrauliques ou encore pneumatiques peuvent être associés au container pour accélérer sa vitesse de remontée.Indeed, mechanical, pyrotechnic, hydraulic or pneumatic means may be associated with the container to accelerate its ascent rate.
Il peut en effet être particulièrement avantageux d'obtenir des prises de vue de l'environnement de ce péricope lorsque celui-ci est à l'apogée de sa phase aérienne au-dessus de la surface de l'eau, afin d'augmenter la portée de l'observation.It can indeed be particularly advantageous to obtain shots of the environment of this pericope when it is at the peak of its aerial phase above the surface of the water, in order to increase the scope of observation.
Le traitement des images délivrées peut alors être réalisé en temps réel ou encore en temps différé. Bien entendu, les moyens de prise de vue peuvent être formés par des moyens de différentes natures, caméras, appareils photos, IR, etc ...The processed images can then be processed in real time or in deferred time. Of course, the means of shooting can be formed by means of different types, cameras, cameras, IR, etc ...
Par exemple, des essais ont démontré que l'utilisation de quatre caméras disposées à 90° les unes par rapport aux autres, permettait d'obtenir une très bonne surveillance de l'environnement.For example, tests have shown that the use of four cameras arranged at 90 ° relative to each other, allowed to obtain a very good monitoring of the environment.
De même, dès le largage du périscope flottant, celui-ci est à même de délivrer des informations concernant l'environnement lors de son déplacement sous, à et au-dessus de la surface de l'eau.Likewise, as soon as the floating periscope is released, it is able to deliver information concerning the environment during its displacement under, at and above the surface of the water.
De plus, un tel périscope est extrêmement discret, ce qui permet de limiter les risques de détection de l'engin sous-marin.In addition, such a periscope is extremely discreet, which limits the risk of detection of the underwater vehicle.
L'utilisation de moyens de suspension à la cardan associés à la tige et à la masselotte permet de limiter fortement le phénomène d'instabilité des images obtenues, et le résultat obtenu peut être amélioré grâce à un traitement numérique d'images, tel que cela est connu. Bien entendu, d'autres modes de réalisation encore peuvent être envisagés. The use of cardan suspension means associated with the rod and the flyweight makes it possible to greatly limit the phenomenon of instability of the images obtained, and the result obtained can be improved by means of digital image processing, such as that is known. Of course, other embodiments may be envisaged.
