Abstract
L'invention concerne une structure off-shore d'élevage de poissons de volume utile de 700 M3 (fig. ndegré 1) et son dispositif d'immersion/émersion. Le dispositif d'immersion/émersion est constitué d'un système de flottaison (assemblage de modules tubulaires reliés entre eux par des brides) solidaire de l'ensemble (beta) et de deux parachutes ascensionnels (delta) (fig. ndegré 1). Après réglage des volumes d'air dans les parachutes ascensionnels (delta) (par le biais d'un jeu de vannes), et dans les compartiments du système de flottaison (compartiment à air confiné à volume constant), il suffit d'agir sur la seule vanne (23) solidaire de la bouée du narguilé (alpha) (fig. ndegré 1) pour avoir une émersion (par injection d'air à l'aide d'un compresseur ou de bouteilles de plongée) ou immersion (par ouverture de la vanne (23), l'air évacuant alors les ballasts). L"ossature" rigide, et la largeur de l'espace ménagé sur le pourtour du volume utile (filet avec poissons) permet de tendre un "filet" de protection anti-plongeurs et protège le cheptel des risques de compression dus aux plis du filet lors de forts courants sous-marins ou de tempêtes brusques qui surprennent l'ensemble (beta) à des profondeurs non protégées.The invention relates to an off-shore fish rearing structure with a useful volume of 700 M3 (fig. Ndegré 1) and its immersion / emersion device. The immersion / emersion device consists of a flotation system (assembly of tubular modules linked together by flanges) integral with the assembly (beta) and two parasailing (delta) (fig. Ndegré 1). After adjusting the air volumes in the parasailing (delta) (by means of a set of valves), and in the compartments of the flotation system (confined air compartment at constant volume), it suffices to act on the only valve (23) integral with the hookah buoy (alpha) (fig. ndegree 1) to have an emersion (by injection of air using a compressor or diving cylinders) or immersion (by opening valve (23), the air then discharging the ballasts). The rigid "framework", and the width of the space provided around the perimeter of the useful volume (net with fish) allows a "net" to be stretched for anti-diver protection and protects the herd from the risk of compression due to the folds of the net. during strong underwater currents or sudden storms that surprise the whole (beta) at unprotected depths.
Description
Description
La présente invention concerne une structure aquacole (élevage de poissons nobles :loups,daurades... > immergeable ,dtun volume utile de 700 M
Jusqu'à présent,ce type d'élevage s'est effectué surtout en zone protégée estuarienne,lagunaire , voire en bassins alimentés en eau par des pompes puissantes.Description
The present invention relates to an aquaculture structure (breeding of noble fish: wolves, sea bream, etc.> submersible, with a useful volume of 700 M
Until now, this type of farming has been carried out mainly in protected estuarine and lagoon areas, or even in basins supplied with water by powerful pumps.
Les structures immergeables existantes arrivent a résoudre certains problèmes posés aux élevages en mer ouverte , mais trouvent rapidement leurs limites . Elles restent fragiles et d'emploi difficile et contraignant ( surveillance 7 jours sur 7, intervention immediate lors d'un incident). The existing submersible structures manage to solve some of the problems posed to open sea farming, but quickly find their limits. They remain fragile and difficult and restrictive to use (surveillance 7 days a week, immediate intervention in the event of an incident).
Notre structure aquacole immergeable évite tous les problèmes ci-dessus . Son système d'immersion / émersion souple lui permet une bonne assise grâce à sa capacité d'amortissement - un couple de rappel s'exerce en permanence quelles que soient les sollicitations. Par ailleurs, des amarres de sécurité assurent d'une part les parachutes ascensionnels (d) et et autre part la structure aquacole elle-même (b) (amarres non représentées pour ce qui concerne l'ensemble (b)( fig. n 1 ) afin de ne pas surcharger le schéma ). Our submersible aquaculture structure avoids all of the above problems. Its flexible immersion / emersion system allows it to sit well thanks to its damping capacity - a return torque is permanently exerted regardless of the stresses. In addition, safety moorings ensure, on the one hand, the parasailing (d) and, on the other hand, the aquaculture structure itself (b) (moorings not shown for the assembly (b) (fig. N 1) ) so as not to overload the diagram).
L'"ossature"donnée à la structure(b) permet au volume utiles matérialisé par le ou les filet(s) (h), de se maintenir dans les conformations les meilleures - évitant ainsi de nombreux problèmes dont :
*la formation de poches dans les filets (h)o leur tassement
(dangereux pour le cheptel) lors de courants forts ou de tempêtes
brusques surprenant les cages à des profondeurs encore exposées. The "framework" given to structure (b) allows the useful volume materialized by the net (s) (h) to be maintained in the best conformations - thus avoiding many problems including:
* the formation of pockets in the nets (h) o their settlement
(dangerous for livestock) during strong currents or storms
abrupt surprises the cages at still exposed depths.
*La rupture du "narguil@" (a) qui, accidentelle ( section par hélices de bateaux etc...) ou volontaire C malveillance ) , au niveau de certaines structures aquacoles immergeables déjà exploitées, fait émerger la cage et nécessite une intervention rapide - laquelle , par gros temps ,met en danger les hommes le cheptel et la structure elle-même. * The rupture of the "narguil @" (a) which, accidental (section by boat propellers etc ...) or intentional (malicious)), at the level of certain immersible aquaculture structures already in use, causes the cage to emerge and requires rapid intervention - which, in heavy weather, endangers the livestock and the structure itself.
De tels accidents ou déprédations soustraient automatiquement notre structure aquacole immergeable à tout danger, par immersion totale et immédiate. Such accidents or depredations automatically remove our submerged aquaculture structure from any danger, by total and immediate immersion.
En effet, le système d'émersion/immersion de notre structure aquacole immergeable ,fonctionne de la manière suivante
* Immersion
La cage (b) est en surface.L'ouverture de la vanne (23) du narguilé permet à l'air d'évacuer les 5 ballasts (2,4) du système de flottaison (détails figue et 7) La flottabilité de l'ensemble (b) qui diminue graduellement alors , associée a la contre-poussee exercée par les parachutes ascensionnels (d) permet l'immersion et le maintien de cet ensemble(b) en plongée
La profondeur désirée est obtenue par action sur les différents facteurs (conjointement ou non > que représentent l amplitude de la montée des parachutes ascensionnels - par limitation de la course de l amarre (g) , par dosage de la poussée d'Archimède
grAce au jeu de vannes incorporées aux dits parachutes ascensionnels - et le degré de flottabilité imposé à l'ensemble (b) en agissant sur le volume d'air dans les ballasts(2 ,4).Indeed, the emersion / immersion system of our immersible aquaculture structure works as follows
* Immersion
The cage (b) is on the surface The opening of the valve (23) of the hookah allows the air to evacuate the 5 ballasts (2,4) of the flotation system (details fig and 7) The buoyancy of the 'set (b) which then gradually decreases, associated with the counter-thrust exerted by the parasailing (d) allows the immersion and the maintenance of this set (b) in diving
The desired depth is obtained by acting on the various factors (whether or not jointly> represented by the amplitude of the rise of the parasailing) - by limiting the travel of the mooring (g), by dosing the Archimedes thrust
thanks to the set of valves incorporated in the so-called ascending parachutes - and the degree of buoyancy imposed on the assembly (b) by acting on the volume of air in the ballasts (2, 4).
* Emersion
L'émersion est obtenue par injection d'air sous pression grâce à un compresseur ou des bouteilles de plongée.* Emersion
The emersion is obtained by injection of pressurized air using a compressor or diving cylinders.
Enfin ,la rigidite de la cage , alliée a la lumîère(l,5m) ménagée sur le pourtour du volume utile ,permet de tendre efficacement un filet anti-plongeurs(filet métallique à larges mailles). Finally, the rigidity of the cage, combined with the light (1.5m) provided around the perimeter of the useful volume, makes it possible to effectively stretch an anti-diver net (metal net with large meshes).
