Abstract

The beacon (1) has a case enclosing a radio acoustic signal receiver (4), and a mooring rope (11) attached to a mooring point at one end. An electro-mechanical type releasing mechanism i.e. gear motor (7), is enclosed in a sealed tank (5) constituting a reserve of buoyancy. The mechanism controls a ratchet (8) for blocking or allowing free rotation of a winding drum (10) around which the rope is spooled. The gear motor drives the ratchet in cooperation with teeth (9) for forming a ratchet mechanism to ensure unwinding of the rope when a signal is sent to the receiver.

Description

La présente invention a pour objet une balise immergée dotée de moyens assurant sa remontée à la surface sur commande ainsi qu'un système de repérage d'objets immergés mettant en oeuvre ladite balise.The subject of the present invention is a submerged beacon provided with means ensuring its return to the surface on command as well as a system for locating submerged objects using said beacon.

De tels systèmes de balises sous-marines, permettant le repérage d'objets immergés après déclenchement d'un signal, sont plus particulièrement adaptés au repérage et à la récupération d'engins de pêche immergés tels que des palangres, des filets et des casiers de pêche, comme les casiers pour la pêche aux crabes ou aux homards. Ces systèmes de balises immergées permettent avantageusement aux pêcheurs de retrouver leurs engins de pêche mis en place, tout en évitant les problèmes habituellement rencontrés de perte des signaux qui restent en surface, ainsi que le vol des engins de pêche ou le repérage des zones de pêche privilégiées, rendus possibles par la visualisation des signaux de surface.Such submarine beacon systems, allowing the tracking of submerged objects after triggering a signal, are more particularly adapted to the identification and recovery of submerged fishing gear such as longlines, nets and traps. such as fishing traps for crabs or lobsters. These submerged beacon systems advantageously allow fishermen to find their fishing gear in place, while avoiding the problems usually encountered of loss of signals that remain on the surface, as well as the theft of fishing gear or the identification of fishing areas. privileged, made possible by the visualization of surface signals.

Différentes solutions techniques de balises immergées ont déjà été imaginées.Various technical solutions for submerged beacons have already been devised.

On connaît ainsi, selon le brevet américain US 3 722 014 , une bouée sous-marine comportant un mécanisme de libération d'une corde à laquelle est rattachée la bouée, un récepteur de signaux acoustiques déclenchant la libération et un système à déclenchement par explosifs, le tout étant renfermé dans un boîtier cylindrique dont le fond se sépare au moment de l'explosion pour libérer la corde enroulée autour du boîtier. Dans une seconde variante, le dispositif comprend une bouée gonflable dont le gonflement est déclenché par la rupture d'une vanne reliée à une bouteille de gaz au moment de l'explosion.So we know, according to the US patent US 3,722,014 , an underwater buoy comprising a rope release mechanism to which the buoy is attached, a release acoustic signal receiver and an explosive trigger system, all enclosed in a cylindrical housing whose bottom is separates at the moment of the explosion to release the rope wrapped around the case. In a second variant, the device comprises an inflatable buoy whose inflation is triggered by the rupture of a valve connected to a gas cylinder at the time of the explosion.

Le brevet européen EP 0.686.553 décrit un autre système de libération dans lequel une batterie, en réponse à des signaux acoustiques, déclenche des moyens de chauffage afin de liquéfier une substance expansible qui va entraîner le déplacement d'un levier permettant d'actionner le mécanisme de libération de la bouée.The European patent EP 0.686.553 describes another release system in which a battery, in response acoustic signals, triggers heating means to liquefy an expandable substance that will cause the movement of a lever for actuating the buoy release mechanism.

On connaît également des systèmes de libération à commandes mécaniques. Ainsi, le brevet US 5.513.886 propose un système de crochet à échappement dont le pivotement est commandé par une came motorisée suite à la réception du signal de libération ; le brevet US 6.378.202 propose, quant à lui, un système de pince dont les deux branches sont écartées lorsque le signal de libération est reçu.Release systems with mechanical controls are also known. Thus, the patent US5,513,886 proposes an exhaust hook system whose pivoting is controlled by a motorized cam following the reception of the release signal; the patent US 6,378,202 proposes, meanwhile, a gripper system whose two branches are separated when the release signal is received.

Un autre exemple de réalisation est donné dans le brevet US3.310.820 , qui est consideré comme étant l'état de la technique le plus proche: la balise immergée comporte une minuterie commandant un cliquet de blocage d'un tambour autour duquel est enroulé un câble relié au flotteur. Une fois le temps imparti écoulé, le cliquet est désengagé du tambour qui peut alors se dévider.Another embodiment is given in the patent US3.310.820 , which is considered to be the closest state of the art: the immersed beacon has a timer controlling a locking pawl of a drum around which is wound a cable connected to the float. Once the time elapsed, the pawl is disengaged from the drum which can then unwind.

Enfin, le brevet US 6.880.290 propose une solution évitant la perte de casiers de pêche, dans laquelle la bouée sous-marine est reliée au casier par des attaches biodégradables, dont la désagrégation complète est assurée après plusieurs semaines en immersion et permet ainsi de retrouver des casiers qui seraient perdus. Par contre, ce système ne comporte pas de dispositif de libération sur commande.Finally, the patent US 6,880,290 proposes a solution avoiding the loss of fishing traps, in which the underwater buoy is connected to the trap by biodegradable fasteners, the complete disintegration is ensured after several weeks in immersion and thus allows to find traps that would be lost. However, this system does not include a custom release device.

L'ensemble de ces systèmes connus est relativement complexe sur le plan mécanique, ne propose pas nécessairement la réunion des différents éléments (bouée, système acoustique de réception, mécanisme de libération) au sein d'un même boîtier, et représente généralement un coût important de fonctionnement.All these known systems is relatively complex mechanically, does not necessarily propose the meeting of the various elements (buoy, acoustic receiving system, release mechanism) within the same housing, and generally represents a significant cost Operating.

La présente invention a donc pour but de proposer un dispositif alternatif de balises immergées comportant des moyens assurant à volonté sa remontée à la surface, de conception simple et robuste, facile d'utilisation et d'un prix de revient peu élevé.The purpose of the present invention is therefore to propose an alternative device for immersed beacons comprising means ensuring at will its ascent to the surface, of simple and robust design, easy to use and low cost.

A cet égard, la présente invention a pour objet une balise immergée constituée d'un boîtier renfermant un récepteur, d'un signal radioacoustique, d'une amarre rattachée à l'une de ses extrémités à un point d'amarrage, d'un mécanisme de libération de la balise permettant sa remontée à la surface et d'une réserve de flottabilité, remarquable en ce que le mécanisme de libération est du type électro-mécanique et est enfermé dans une cuve hermétique constituant ainsi la réserve de flottabilité, ledit mécanisme commandant un cliquet bloquant ou non la rotation libre d'un tambour enrouleur autour duquel l'amarre est bobinée.In this regard, the present invention relates to a submerged beacon consisting of a housing enclosing a receiver, a radioacoustic signal, a tether attached to one of its ends at a docking point, a mechanism for releasing the beacon allowing its return to the surface and a reserve of buoyancy, remarkable in that the release mechanism is of the electromechanical type and is enclosed in a hermetic tank thus constituting the reserve of buoyancy, said mechanism controlling a pawl blocking or not the free rotation of a drum drum around which the mooring is wound.

On comprend bien que la balise selon l'invention est donc de conception très simple et que son fonctionnement est entièrement réversible. En outre, on voit bien que la remontée à la surface initialement entraînée par la réserve de flottabilité est ensuite assurée par l'espace libéré par le déroulement de l'amarre, augmentant ainsi la poussée d'Archimède et accélérant la remontée à la surface.It is understood that the beacon according to the invention is therefore very simple in design and that its operation is completely reversible. In addition, it is clear that the rise to the surface initially driven by the buoyancy reserve is then ensured by the space released by the unfolding of the mooring, thus increasing the buoyancy and accelerating the recovery to the surface.

D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre d'une variante d'exécution de la balise immergée selon l'invention en référence aux dessins annexés sur lesquels :

  • la figure 1 est une vue en perspective de la balise selon l'invention ;
  • la figure 2 est une vue partielle et en coupe longitudinale de la balise représentée à la figure 1 ;
  • la figure 3 est une vue agrandie en perspective partielle du voile du tambour enrouleur portant la dentition du mécanisme à rochet.
Other advantages and features will become more apparent from the following description of an alternative embodiment of the immersed beacon according to the invention with reference to the accompanying drawings in which:
  • the figure 1 is a perspective view of the beacon according to the invention;
  • the figure 2 is a partial view in longitudinal section of the beacon shown in FIG. figure 1 ;
  • the figure 3 is an enlarged partial perspective view of the veil of the winding drum carrying the dentition of the ratchet mechanism.

En référence aux figures 1 à 3, la balise 1 selon l'invention est constituée d'un boîtier 2 de forme globalement inscrite dans un cylindre. Selon une variante particulièrement préférée, ce boîtier 2 est constitué de deux demi-coques 3 assemblées par vissage ou rivetage entre elles. De préférence, la forme du boîtier présente un profil hydrodynamique qui lui permet avantageusement d'être peu sensible aux courants marins. Ce boîtier 2 renferme dans sa partie supérieure un récepteur 4 de signal radioacoustique. Ce récepteur 4 surplombe une cuve hermétique 5 (représentée en pointillés sur la figure 2) qui contient une carte électronique 6 en liaison avec le récepteur 4, une batterie (non représentée) et un moyen d'entraînement constitué par un motoréducteur 7. Le motoréducteur 7 entraîne un cliquet 8 coopérant avec une dentition 9 pour former un mécanisme à rochet, ladite dentition telle que représentée de manière agrandie sur la figure 3 étant disposée à la périphérie sur la face externe d'un des voiles du tambour enrouleur 10 autour duquel une amarre 11 est bobinée pour permettre son libre déroulement, lorsqu'un signal radioacoustique adéquat est envoyé au récepteur 4. L'homme de l'Art pourra mettre en oeuvre d'autres moyens qu'un motoréducteur pour réaliser le moyen d'entraînement, comme par exemple un dispositif à électroaimant et ce, sans sortir du cadre de la présente invention.With reference to Figures 1 to 3 , the beacon 1 according to the invention consists of a housing 2 of form globally inscribed in a cylinder. According to a particularly preferred variant, this housing 2 consists of two half-shells 3 assembled by screwing or riveting them. Preferably, the shape of the housing has a hydrodynamic profile which advantageously allows it to be insensitive to marine currents. This housing 2 contains in its upper part a radioacoustic signal receiver 4. This receiver 4 overhangs a hermetic tank 5 (shown in dashed lines on the figure 2 ) which contains an electronic card 6 in conjunction with the receiver 4, a battery (not shown) and a drive means constituted by a geared motor 7. The geared motor 7 drives a pawl 8 cooperating with a dentition 9 to form a ratchet mechanism said dentition as shown enlarged on the figure 3 being disposed peripherally on the outer face of one of the webs of the winding drum 10 around which a tether 11 is wound to allow its free unwinding, when a suitable radioacoustic signal is sent to the receiver 4. The skilled person may implement other means that a geared to achieve the drive means, such as an electromagnet device and without departing from the scope of the present invention.

Une sortie 12 pour l'amarre 11 est aménagée à l'extrémité opposée du boîtier par rapport au récepteur 4 et une trappe d'accès 13 au tambour 10 est aménagée dans une paroi latérale du boîtier 13. Selon une caractéristique de l'invention, l'axe de rotation du tambour 10 est perpendiculaire à la direction longitudinale de la balise, de sorte que le plan de rotation soit parallèle à l'axe de déroulement de l'amarre 11.An outlet 12 for the tether 11 is arranged at the opposite end of the housing with respect to the receiver 4 and an access hatch 13 to the drum 10 is arranged in a side wall of the housing 13. According to one characteristic of the invention, the axis of rotation of the drum 10 is perpendicular to the longitudinal direction of the beacon, so that the plane of rotation is parallel to the axis of unwinding of the line 11.

En référence à la figure 2, le boîtier 2 est muni d'un logement longitudinal 14 destiné à accueillir un mât d'équilibrage, non représenté, et le repérage en surface de la balise 1.With reference to the figure 2 , the housing 2 is provided with a longitudinal housing 14 intended to receive a mast balancing, not shown, and the identification on the surface of the beacon 1.

Selon une caractéristique avantageuse de l'invention, le tambour enrouleur 10 est monté sur un axe de rotation dont l'une des extrémités 15, avantageusement munie d'un carré d'entraînement, émerge à l'extérieur du boîtier 2 assemblé, permettant ainsi à l'utilisateur de réenrouler l'amarre 11 autour du tambour 10 en utilisant un outil électroportatif ou manuel tel qu'une manivelle de WINCH.According to an advantageous characteristic of the invention, the winding drum 10 is mounted on an axis of rotation of which one of the ends 15, advantageously provided with a driving square, emerges outside the assembled housing 2, thus allowing the user to rewind the tether 11 around the drum 10 using a power tool or manual such as a winch crank.

On comprend bien que le système mécanique de l'invention est extrêmement fiable et peut être réamorcé très facilement sur un bateau de pêche par réenroulement manuel de l'amarre 11 autour du tambour 10, puis envoi d'un signal réengageant le cliquet 8 dans la dentition 9 du tambour 10 afin de bloquer sa rotation. Bien sûr, le réarmement du dispositif pourra être contrôlé automatiquement par une minuterie.It is understood that the mechanical system of the invention is extremely reliable and can be rebooted very easily on a fishing boat by manual rewinding of the tether 11 around the drum 10, and sending a signal reengaging the pawl 8 in the teething 9 of the drum 10 to block its rotation. Of course, the rearming of the device can be controlled automatically by a timer.

Selon une caractéristique préférentielle, la batterie est du type accumulateur rechargeable. La recharge de cette batterie pourra être assurée par l'intermédiaire d'une connectique étanche ou par induction, selon le choix que retiendra l'Homme de l'Art.According to a preferred characteristic, the battery is of the rechargeable accumulator type. The recharging of this battery can be provided by means of a sealed connection or induction, depending on the choice that will retain the Man of Art.

Selon une variante, la balise 1 est équipée d'un dispositif additionnel non représenté sur les figures, ajouté à l'extérieur de celle-ci permettant d'ajuster la profondeur d'immersion de ladite balise 1. Ce dispositif consiste en un boîtier renfermant un moteur d'enroulement associé à un profondimètre et alimenté par une batterie autonome, par exemple du type au sel qui permet une charge électrique constante dès que la balise 1 est immergée. Le dispositif sera avantageusement disposé de manière à ce que le moteur d'enroulement soit relié à l'extrémité émergente 15 de l'axe de rotation du tambour 10. Dans une variante préférée (figure 3) où le cliquet 8 bloque uniquement la rotation dudit tambour dans le sens du déroulement de l'amarre 11, le dispositif additionnel réajustera la profondeur d'immersion de la balise 1 soit en procurant l'enroulement supplémentaire afin de la faire descendre, soit en débloquant le tambour en envoyant un signal à la balise 1 jusqu'à ce qu'elle atteigne une profondeur inférieure à la profondeur visée, puis en enroulant l'amarre jusqu'à atteindre la profondeur voulue. La communication entre le dispositif additionnel pourra être filaire, par le biais d'une connectique étanche, ou non filaire, de préférence par ondes à très courte portée. Ce dispositif additionnel de contrôle de profondeur permet avantageusement d'éviter la perte d'une balise immergée en cas d'erreur de largage de celle-ci dans une zone où elle se retrouverait à une profondeur supérieure à la longueur prévue de l'amarre 11, ce qui empêcherait la remontée à la surface de la balise et donc sa récupération. En outre, dans les cas de marée, ce dispositif additionnel permet d'ajuster précisément la longueur de câble nécessaire de l'amarre 11 pour que la balise 1 arrive en surface et permet donc ainsi de limiter la dérive en surface de ladite balise lorsque celle-ci est libérée.According to a variant, the beacon 1 is equipped with an additional device not shown in the figures, added to the outside thereof to adjust the immersion depth of said beacon 1. This device consists of a housing containing a winding motor associated with a depth gauge and powered by a self-contained battery, for example of the salt type which allows a constant electric charge as soon as the beacon 1 is immersed. The device will advantageously be arranged in such a way that the winding motor is connected to the emergent end 15 of the axis of rotation of the drum 10. In a preferred variant ( figure 3 ) where the ratchet 8 blocks only the rotation of said drum in the direction of unwinding of the tether 11, the additional device will readjust the depth of immersion of the beacon 1 either by providing the additional winding to lower it, or by unlocking the drum by sending a signal to beacon 1 until it reaches a depth less than the target depth, then winding up the line until it reaches the desired depth. The communication between the additional device may be wired, via a sealed connection, or non-wired, preferably by very short-range waves. This additional depth control device advantageously makes it possible to avoid the loss of a submerged beacon in the event of an error in its release in an area where it would be at a depth greater than the planned length of the tether 11 , which would prevent the return to the surface of the tag and thus its recovery. In addition, in the case of tide, this additional device makes it possible to precisely adjust the necessary cable length of the tether 11 so that the beacon 1 arrives at the surface and thus makes it possible to limit the drift at the surface of said beacon when that it is released.

Selon une caractéristique additionnelle, la balise 1 est équipée d'un système de sécurité pour les cas de défaillances électriques liées à un problème de charge des accumulateurs commandant le motoréducteur 7 ou à un problème d'étanchéité, ce dispositif entraînant le désengagement automatique du cliquet 8 et ainsi la remontée de la balise 1 en surface.According to an additional characteristic, the beacon 1 is equipped with a safety system for cases of electrical failures related to a problem of charging the accumulators controlling the geared motor 7 or a sealing problem, this device causing the automatic disengagement of the ratchet 8 and thus the recovery of the beacon 1 on the surface.

Le dispositif de balise selon l'invention sera mis en oeuvre de préférence dans un système de repérage d'objets immergés.The beacon device according to the invention will preferably be implemented in a system for marking submerged objects.

La présente invention a donc pour second objet un système de repérage d'objets immergés à l'aide de balises immergées libérant un signal de surface suite à la réception de signaux acoustiques de déclenchement, ledit système comportant un émetteur et un jeu de balises. Ce système de repérage est remarquable en ce que, d'une part, l'émetteur est constitué d'une centrale émettrice connectée à un transducteur immergé et, d'autre part, les balises sont telles que décrites précédemment.The object of the present invention is therefore a system for locating immersed objects using tags. immersed releasing a surface signal following receipt of acoustic trigger signals, said system comprising a transmitter and a set of tags. This marking system is remarkable in that, on the one hand, the transmitter consists of an emitting unit connected to a submerged transducer and, on the other hand, the beacons are as described above.

Cette configuration particulière de l'émetteur permet avantageusement d'avoir un rayon d'émission omnidirectionnel.This particular configuration of the transmitter advantageously makes it possible to have an omnidirectional transmission radius.

De préférence, la centrale émettrice comportera un module de gestion automatique des codes d'activation des balises, par exemple en connexion avec un système de positionnement global (GPS). En outre, une fonction d'activation de l'ensemble des balises présentent sur un site pourra être prévue, en émettant successivement l'intégralité des codes de signaux prévus. De préférence, le système d'émission permet de gérer plus de 64000 codes de déclenchement avec une seule fréquence, ce qui permet d'individualiser le code de déclenchement de chacune des balises. De façon pratique, la portée du système sera de plus de 500 mètres, de façon optimale avec un rayon d'émission d'environ 800 mètres.Preferably, the sending station will comprise an automatic management module tag activation codes, for example in connection with a global positioning system (GPS). In addition, an activation function of all the tags present on a site may be provided, emitting successively all the signal codes provided. Preferably, the transmission system can handle more than 64,000 trigger codes with a single frequency, which allows to individualize the trigger code of each of the tags. In practical terms, the range of the system will be more than 500 meters, optimally with an emission radius of about 800 meters.

Le système de repérage d'objets immergés selon l'invention permet donc avantageusement de gérer avec un seul émetteur une flotte de balises, ce qui réduit substantiellement les coûts d'utilisation du système et assure la rentabilité de l'investissement pour les utilisateurs. En outre, on comprend bien que le grand nombre de codes gérés par le système d'émission assure la sécurité du dispositif, dans les cas où plusieurs utilisateurs du système selon l'invention fréquentent des zones géographiques proches ou identiques.The system for locating immersed objects according to the invention therefore advantageously makes it possible to manage with a single transmitter a fleet of tags, which substantially reduces the costs of using the system and ensures the profitability of the investment for the users. Furthermore, it is well understood that the large number of codes managed by the transmission system ensures the security of the device, in cases where several users of the system according to the invention frequent near or identical geographical areas.

Dans le cas d'un bateau de pêche, le transducteur du système de repérage sera positionné sous la coque dans le dernier tiers arrière du bateau : en effet, cette partie est la moins exposée aux turbulences lorsque le bateau est en déplacement.In the case of a fishing vessel, the transducer of the tracking system will be positioned under the hull in the last third of the boat: indeed, this part is the least exposed to turbulence when the boat is on the move.

Enfin, la centrale émettrice comporte une interface utilisateur, avec notamment un clavier et un écran d'affichage permettant de proposer à l'utilisateur différentes options de gestion des codes de déclenchement.Finally, the sending station has a user interface, including a keyboard and a display screen to provide the user with different options for managing the trigger codes.

On comprend bien que l'application principale de la balise immergée selon l'invention est destinée aux engins de pêche immergés. Toutefois, l'invention trouvera avantageusement une autre application dans la gestion des emplacements d'amarrage, c'est-à-dire des anneaux dans les ports de plaisance. On associera les balises immergées selon l'invention à un système d'émetteur central lié à un serveur et à un terminal bancaire qui déclenchera la remontée d'une balise immergée portant un anneau lié à un câble d'amarrage, suite au paiement requis pour l'obtention d'une place dans le port de plaisance.It is understood that the main application of the submerged beacon according to the invention is for submerged fishing gear. However, the invention will advantageously find another application in the management of mooring locations, that is to say, rings in marinas. The submerged beacons according to the invention will be associated with a central transmitter system linked to a server and to a banking terminal which will trigger the ascent of a submerged beacon carrying a ring connected to a mooring cable, following the payment required for obtaining a place in the marina.

Le système selon l'invention peut également être utilisé pour neutraliser des accès à certaines zones comme des chenaux ou des passerelles le long desquelles les bateaux peuvent être amarrés. Toutefois, dans cette application il faudra prévoir un boîtier externe supplémentaire avec un moteur entraînant l'enroulement de l'amarre 11 autour du tambour 10 afin d'immerger la balise 1, le système étant au repos et en surface lorsque l'accès doit être interdit. On pourra également envisager d'utiliser la balise selon l'invention pour délimiter à la demande une zone sensible, par exemple une épave ou des mines marines.The system according to the invention can also be used to neutralize access to certain areas such as channels or bridges along which the boats can be moored. However, in this application it will be necessary to provide an additional external housing with a motor causing the winding of the tether 11 around the drum 10 to immerse the beacon 1, the system being at rest and on the surface when the access must be not allowed. It will also be possible to use the beacon according to the invention to delimit on demand a sensitive area, for example a wreck or mines.

Enfin il va de soi que la forme d'exécution de la balise 1 selon l'invention n'est qu'une variante particulière en aucun cas limitative des adaptations que l'Homme de l'Art pourrait y apporter.Finally, it goes without saying that the embodiment of the beacon 1 according to the invention is only a particular variant in no way limiting the adaptations that the Man of Art could bring it.
