Description
Oppfinnelsen angår en løsning ved flatbunnet merdkonstruksjon spesielt rettet mot flat og stabil bunnkonstruksjon med mulighet for heving/senking til ønsket dybde. Samtidig som det skal være mulig for personell til fysisk å gå på bunnen når denne er i overflateposisjon. Heving/senking foregår pneumatisk, styrt fra overflaten. The invention relates to a solution for a flat-bottomed cage construction, particularly aimed at a flat and stable bottom construction with the possibility of raising/lowering to the desired depth. At the same time, it must be possible for personnel to physically walk on the bottom when it is in surface position. Raising/lowering takes place pneumatically, controlled from the surface.
Oppdrett av fisk er blitt en betydelig næring. De store oppdrettsvolumene og inntektene, er p.r. dag knyttet til oppdrett av anadrome arter som laks, sjøørret og røye. Det anses at marine arter vil kunne ha stor betydning for konvensjonell oppdrett i fremtiden. Kveite, steinbit og piggvar, er arter det knytter seg stor interesse til fremover. Disse artene er bunnfisker som oppholder seg det meste av tiden på bunnen. Den forskning og erfaring som finnes, er knyttet til oppdrett i lengdestrømsrenner og oppdrettskar på land. Denne teknologien egner seg best til yngel og for små individer i tidlig matfisk-produksjonsstadie. Teknologien, landbasert, vil være svært kostbar for matfiskproduksjonen med hensyn til vann, areal — og energibehov. Ny løsning som flatbunnet merd bør benyttes hvis oppdrett av kveite, steinbit og piggvar skal bli lønnsom (sjøbasert oppdrett). I tillegg vil det bli behov for lagring og oppforing av levendefanget villfisk, kveite, steinbit, flyndre og torsk samt kongekrabbe og kråkeboller o.l. Flatbunnet merd vil være spesielt tilpasset dette behovet. Fish farming has become a significant industry. The large farming volumes and income are p.a. day related to the farming of anadromous species such as salmon, sea trout and char. It is considered that marine species will be of great importance for conventional farming in the future. Halibut, catfish and turbot are species that will be of great interest in the future. These species are demersal fish that spend most of their time on the bottom. The research and experience that exists is linked to farming in longitudinal flow channels and farming vessels on land. This technology is best suited for fry and for small individuals in the early food fish production stage. The technology, based on land, will be very expensive for food fish production in terms of water, land and energy requirements. A new solution such as a flat-bottomed cage should be used if the farming of halibut, catfish and turbot is to become profitable (sea-based farming). In addition, there will be a need for storage and feeding of live caught wild fish, halibut, catfish, flounder and cod as well as king crab and sea urchins etc. A flat-bottomed cage will be specially adapted to this need.
Torsk som levendefanges til oppforing eller levendelagring, vil ha sprengt svømmeblære. Dette er ønskelig i fangstmetoden. Svømmeblæren til torsken rehabiliteres ved at fisken ligger i ro på en flat bunn ca 1-2 døgn. Torsken blir da pelagisk og kan overføres til en "vanlig" merd. Cod caught live for feeding or live storage will have a ruptured swim bladder. This is desirable in the capture method. The swim bladder of the cod is rehabilitated by the fish lying at rest on a flat bottom for about 1-2 days. The cod then becomes pelagic and can be transferred to a "normal" cage.
Flatbunnede merder hvor man kan heve og senke bunnet med Flat-bottomed cages with which you can raise and lower the bottom
påliggende nettpose gir muligheter til sjøbasert oppdrett med de driftsmessige fordeler dette gir kontra landbasert kardrift. Heving av merdebunnen/nettposen opp til en dybde slik at personell fysisk kan gå på bunnen gir anledning til røkting, kontroll og sortering på en enkel og effektiv måte. attached net bag provides opportunities for sea-based farming with the operational advantages this provides compared to land-based tank farming. Raising the cage bottom/net bag up to a depth so that personnel can physically walk on the bottom provides an opportunity for smoking, checking and sorting in a simple and efficient way.
I NO- 303.313 viser en løsningen med flatbunnet merd hvor en trapolinebunn danner et flatt underlag for nettposen. Trampolinebunnen fremskaffes ved at det mellom en ytre sirkulær bunnring og en innenfor denne beliggende bardunring og i felles senter av disse en senterring. Mellom disse finnes barduner som strammes opp og danner trampolinebunnen hvor nettposen ligger an. Senterringen utgjør en del av et strammesystem nettbunnen, hvor det knyttet til senterringen finnes en basisring beliggende nærmere sjøbunnen og anordnet stivt til senterringen via stenger. For å fa et vertikalt stabilt system så er det også anordnet barduner mellom bunnringen og basisringen. Bunnringen er anordnet via wirer (stag, glider) til en flytering. Nettposen er anordnet til flyteringen og vertikalt glibar til wirene slik at nettposen kan heves og senkes i forhold til flyteringen hvilket gjør at nettposens bunn kan forflyttes vertikalt i vannet. Bardunringen består av to i noe avstand fra hverandre horisontalt beliggende ringer, en ytre barduring og en indre barduring. Mellom disse to bardunringene befinner det seg en hevering som kan tilføres komprimert luft/gass for å kunne endres oppdriften på og dermed kunne heve/senke trampolinebunnen med nettposen på. NO-303,313 shows a solution with a flat-bottomed cage where a trapoline bottom forms a flat base for the net bag. The trampoline bottom is provided by placing between an outer circular bottom ring and a bar dunn ring located within this, and in the common center of these a center ring. Between these there are bar downs that are tightened and form the bottom of the trampoline where the net bag rests. The center ring forms part of a tensioning system on the bottom of the net, where connected to the center ring there is a base ring located closer to the seabed and arranged rigidly to the center ring via rods. In order to obtain a vertically stable system, bar dunes are also arranged between the bottom ring and the base ring. The bottom ring is arranged via wires (stays, sliders) to a floating ring. The net bag is arranged for the floating ring and vertically slidable to the wires so that the net bag can be raised and lowered in relation to the floating ring, which means that the bottom of the net bag can be moved vertically in the water. The bardun ring consists of two horizontally situated rings at some distance from each other, an outer bardur ring and an inner bardur ring. Between these two bar du rings there is a riser that can be supplied with compressed air/gas in order to be able to change the buoyancy and thus be able to raise/lower the trampoline bottom with the net bag on it.
Den løsningen som er beskrevet i NO-303.313 knyttet til heving/senking av trampolinebunnen med bunnring, bardunring og senterring, viser seg noen for kompleks teknisk i praktisk bruk. Videre er senterstrammingen av bunnettet også noe for komplekst til å kunne gi den store praktiske anvendelsen. Trampolinebunnen med strammesystem, blir for komplekst og kostbart å produsere. The solution described in NO-303,313 related to raising/lowering the trampoline bottom with bottom ring, bar dunn ring and center ring, turns out to be technically too complex in practical use. Furthermore, the center tightening of the bottom grid is also somewhat too complex to be able to provide the large-scale practical application. The trampoline base with a tensioning system is too complex and expensive to produce.
Hensikten ved foreliggende oppfinnelse er å fremskaffe flatbunnet merdesystem som lettere kan betjenes og opereres med hensyn, røkting og rengjøring. The purpose of the present invention is to provide a flat-bottomed cage system that can be more easily operated and operated with regard to smoking and cleaning.
Dette oppnås en mangekantet bunnring som har et antall hjørner hvor det fra disse til toppunkter i det minste i nærheten av en sentertank er anordnet toppstag og at fra hjørnene til bunnpunkter i det minste i nærheten av sentertanken er anordnet bunnstag idet bunnringen via et 1. sett løkker er glidende anordnet til glidere hvilke videre er anordnet med sin ene ende til flyteringen og i andre enden et lodd og hvor nettposen er glidende anordnet via et 2. sett løkker til glideren og hvor wirer er festet til flyteringene og i sin andre ende festet til bunnringen . This is achieved by a polygonal bottom ring which has a number of corners where top braces are arranged from these to top points at least near a center tank and from the corners to bottom points at least near the center tank bottom braces are arranged, the bottom ring via a 1st set loops are slidingly arranged to sliders which are further arranged with one end to the floating ring and at the other end a plumb line and where the net bag is slidingly arranged via a 2nd set of loops to the slider and where wires are attached to the floating rings and at its other end attached to the bottom ring.
Ytterligere detaljer ved oppfinnelsen vil fremgå av den etterfølgende beskrivelsen med henvisning til tegningene av et utførelseseksempel på oppfinnelsen. Figur 1 sammenstilling av komplett merd med flytering, bunn og nettpose. Further details of the invention will appear from the following description with reference to the drawings of an embodiment of the invention. Figure 1 assembly of a complete cage with float ring, bottom and net bag.
Figur 2 viser horisontalt riss av bunnring med sentertank. Figure 2 shows a horizontal view of the bottom ring with central tank.
Figur 3 viser vertikalt tverrsnitt i bunnring og sentertank. Figure 3 shows a vertical cross-section in the bottom ring and center tank.
Figur 4 viser bunnen anordnet til flyteringene. Figure 4 shows the bottom arranged for the floating rings.
Merdsystemet består av flyteringer 1, en bunn 2 og mellom disse vertikale glidere 3 og wirer 4. Inne i denne rammen utformet av nevnte elementer og liggende an på bunnen 2, befinner en nettpose 5 seg. The cage system consists of floating rings 1, a bottom 2 and between these vertical sliders 3 and wires 4. Inside this frame formed by the aforementioned elements and resting on the bottom 2, a net bag 5 is located.
Bunnen 2 har som funksjon å være anlegg for nettposen 5 og å forme den slik at en flat bunn oppnås. Bunnen 2 må være så stram at personell kan gå på den. The function of the bottom 2 is to be a facility for the net bag 5 and to shape it so that a flat bottom is achieved. The bottom 2 must be so tight that personnel can walk on it.
Figur 2 viser hvordan bunnen 2 kan utformes. En ytre ramme for bunnen 2 utgjøres av en bunnring 6 som har en mangekantet form. Fra hvert hjørne 7 i mangekanten og til senterpunkt 8 på en sentertank 9, finnes toppstag 10 som kan strammes opp for å oppnå et tilstrekkelig grunnlag for nettposen 5. Stagene 10,12 kan være utformet i wirer som materiale. Sentertanken 9 har en vertikal lengde og hvor det fra bunnringen 6 til bunnpunkter 11 i sentertanken 9 nærmest sjøbunnen, er anordnet bunnstag 12. Sentertanken 9 utgjør således forankring av stagene 10,12 for å kunne oppnå en stram bunn 2. En alternativ måte vil være at stagene 10,12 mot senter er anordnet noe utenfor sentertanken 9 for eksempel på en ring/sylinderform og hvor sentertanken 9 befinner seg inne i denne. Figure 2 shows how the bottom 2 can be designed. An outer frame for the bottom 2 is formed by a bottom ring 6 which has a polygonal shape. From each corner 7 in the polygon and to the center point 8 of a center tank 9, there are top struts 10 which can be tightened to obtain a sufficient foundation for the net bag 5. The struts 10,12 can be designed in wires as material. The center tank 9 has a vertical length and where from the bottom ring 6 to the bottom points 11 in the center tank 9 closest to the seabed, a bottom stay 12 is arranged. that the rods 10,12 towards the center are arranged somewhat outside the center tank 9, for example in a ring/cylindrical shape and where the center tank 9 is located inside this.
Sentertanken 9 kan fylles delvis med vann og luft/gass i ønsket mengde for å oppnå ekstra oppdrift. Disse mengder kan styres med ventiler og styreutrustning fra flytende enheter ved eller på flyteringen. The center tank 9 can be partially filled with water and air/gas in the desired amount to achieve extra buoyancy. These quantities can be controlled with valves and control equipment from floating units at or on the floating ring.
Gliderne 3 i materiale som wire eller tau, er forankret til The sliders 3 in material such as wire or rope are anchored to
flyteringene 1 og har i sin nedre ende nærmest bunnen 2 lodd 13. Gliderne 3 løper gjennom et 1. sett løkker 14 som er anordnet til bunnringen 6, og et 2. sett løkker 15 som er fast oppover langs nettposen 5. Mellom hver av løkkene 15 befinner det seg flyteelementer 16 som er tredd inn på glidere 3 og løper fritt på denne mellom to løkkene 15. the floating rings 1 and has at its lower end closest to the bottom 2 plumb bob 13. The sliders 3 run through a 1st set of loops 14 which are arranged to the bottom ring 6, and a 2nd set of loops 15 which are fixed upwards along the net bag 5. Between each of the loops 15 there are floating elements 16 which are threaded onto sliders 3 and run freely on this between the two loops 15.
Wirer 4 fast til flyteringene 1 og bunnringen 6, har fast feste til pose 5 på flere steder mellom flyteringen 1 og bunnen 2 på noe tilsvarende måte som glider 3. Bunnen 2 heves ved å tilføres passe mengde luft til sentertanken 9. Bunnen 2 driver da nettposen 5 opp mot flyteringene 1 ved hjelp av den oppdriften som finnes i flyteelementer 16. Det som tilføres av luftmengde til sentertanken 9, vil kunne være slik at når bunnen befinner seg for eksempel 0,5 -1,0 m under flyteringene 1 så balanserer det vektmessige slik at røktere kan gå på bunnen 2 å foreta nødvendig arbeid. Wirer 4 fixed to the floating rings 1 and the bottom ring 6, has a fixed attachment to the bag 5 in several places between the floating ring 1 and the bottom 2 in a similar way to sliding 3. The bottom 2 is raised by supplying the right amount of air to the center tank 9. The bottom 2 then drifts the net bag 5 up against the float rings 1 with the help of the buoyancy found in the float elements 16. The amount of air supplied to the central tank 9 could be such that when the bottom is for example 0.5 - 1.0 m below the float rings 1 then balances the weight-wise so that breeders can go on the bottom 2 to carry out the necessary work.
Wirene 4 er forsynt med strekkavlaster 17 for demping av bølgebevegelser / hydrodynamikk. Glider 3 vil dempe av bølger / hydrodynamikk ved at denne beveger seg vertikalt (opp/ned) i løkke 14. The wires 4 are provided with strain relief 17 for dampening wave movements / hydrodynamics. Glider 3 will dampen waves / hydrodynamics by moving vertically (up/down) in loop 14.
Rundt periferien av flyteringen 1 kan man ha en eller annen kombinasjon av glidere 3 og wirer 4, f. eks. annen hver eller bare den ene typen eller bare den andre typen. Around the periphery of the floating ring 1, one can have some combination of sliders 3 and wires 4, e.g. different each or only one type or only the other type.
