Description
Den foreliggende oppfinnelse vedrører en anordning ved fiskeoppdrettskar som i en ende er utstyrt med innløp for vann og, som i den motstående er utstyrt med utløp for vannet. The present invention relates to a device for fish breeding vessels which is equipped at one end with an inlet for water and which is equipped with an outlet for the water at the opposite end.
Det er kjent at vanngjennomstrømningen som er nødvendig i oppdrettskar er avhengig av en rekke faktorer, bl.a. an-tallet fisk, fiskestørrelsen, vannets strømningsprofil og oksygeninnhold. It is known that the water flow which is necessary in breeding tanks depends on a number of factors, i.a. the number of fish, the fish size, the water's flow profile and oxygen content.
Med vannets strømningsprofil menes et bilde av vannets hastighet på forskjellige steder i oppdrettskaret. Vannhastig-heten vil være høyere inne i vannmassen enn langs bunn og vegger, dersom man ikke tar forholdsregler for å endre dette forhold. Som følge av disse varierende vannhastigheter vil oksygeninnholdet i vannet variere, og være lavest ved bunn og vegger. For at oksygenkonsentrasjonen over alt skal være til-strekkelig er det ofte nødvendig å øke vanngjennomstrømningen i uønsket høy grad, med økende omkostninger som resultat. By the water flow profile is meant a picture of the speed of the water at different places in the breeding tank. The water velocity will be higher inside the water mass than along the bottom and walls, if precautions are not taken to change this situation. As a result of these varying water speeds, the oxygen content in the water will vary, and will be lowest at the bottom and walls. In order for the oxygen concentration to be sufficient everywhere, it is often necessary to increase the water flow to an undesirably high degree, with increasing costs as a result.
For å redusere ovennevnte problemer har det vært fore-slått forskjellige typer bunnstrømregulatorer, som sørger for at vann strømmer opp gjennom bunnen av karet på forskjellige steder i dets lengderetning. Derved oppnår man en bedre strømningsprofil, men erfaring har vist at bunnstrømnings-regulatoren virvler opp for som har sedimentert på karets bunn, og det oppvirvlede sediment legger seg på fiskens gjeller, med fare for fiskedød som resultat. In order to reduce the above-mentioned problems, different types of bottom flow regulators have been proposed, which ensure that water flows up through the bottom of the vessel at different places along its length. This achieves a better flow profile, but experience has shown that the bottom flow regulator swirls up what has sedimented on the bottom of the tank, and the swirled sediment settles on the fish's gills, with the risk of fish death as a result.
Det er således behov for bedre løsninger, og med den foreliggende oppfinnelse er det frembrakt en anordning som reduserer problemene. There is thus a need for better solutions, and with the present invention a device has been produced which reduces the problems.
Anordningen ifølge oppfinnelsen er kjennetegnet ved at det i karets vegg(er) er anordnet dyser for innsprøytning av vann i oppdrettskaret, og at dysene er fortrinnsvis regulerbare både sideveis- og i høyderetning. The device according to the invention is characterized by the fact that nozzles are arranged in the wall(s) of the vessel for injecting water into the rearing vessel, and that the nozzles are preferably adjustable both laterally and vertically.
Dysene er fortrinnsvis anordnet i et antall enheter som har innbyrdes avstand i karets lengderetning og som hver omfatter et antall dyser som er anordnet over hverandre. Dysene i hver enhet reguleres samtidig, men hver enhet reguleres for seg. Det blir derved mulig å påvirke strømningsbildet i oppdrettskaret etter behov langs karet. Ved hensiktsmessig retning på dysene kan disse bringes til å "samvirke" med en avløpsrenne i karets bunn og derved øke utsuging av suspenderte partikler i vannet. The nozzles are preferably arranged in a number of units which are spaced apart in the longitudinal direction of the vessel and each of which comprises a number of nozzles which are arranged one above the other. The nozzles in each unit are regulated at the same time, but each unit is regulated separately. This makes it possible to influence the flow pattern in the rearing tank as needed along the tank. If the nozzles are oriented appropriately, these can be made to "cooperate" with a drainage channel in the bottom of the tub and thereby increase the suction of suspended particles in the water.
Anordningen ifølge oppfinnelsen muliggjør således en meget fleksibel regulering av forholdene på forskjellige steder i oppdrettskaret. The device according to the invention thus enables a very flexible regulation of the conditions at different places in the breeding tank.
Oppdrettskarets vegger kan være oppbygget av et modul-system av kassetter. Disse anbringes på et støpt fundament og sammenføyes med hverandre. Derved blir det mulig å bygge oppdrettskaret på en nokså enkel måte og å forandre dets størrelse om det skulle være ønskelig etter at det har vært i bruk en tid. The breeding tank's walls can be made up of a modular system of cassettes. These are placed on a cast foundation and joined together. This makes it possible to build the breeding tank in a fairly simple way and to change its size if desired after it has been in use for some time.
En utførelsesform av oppfinnelsen vil bli beskrevet* i det etterfølgende under henvisning til de medfølgende tegninger, hvor: Fig. 1 viser et skjematisk planriss av anordningen ifølge oppfinnelsen. Fig. 2 viser et vertikal snitt etter linjen A-A i fig. An embodiment of the invention will be described below with reference to the accompanying drawings, where: Fig. 1 shows a schematic plan view of the device according to the invention. Fig. 2 shows a vertical section along the line A-A in fig.
Ifølge fig. 1 tilføres det til et.avlangt oppdrettskar 1 vann gjennom en mateledning 2, som inne i oppdrettskaret går According to fig. 1, water is supplied to an oblong breeding vessel 1 through a feed line 2, which runs inside the breeding vessel
over i en tverrgående vannledning 3 med åpninger 4 som sørger for en jevnere fordeling av vannet i oppdrettskaret. På langs i bunnen av oppdrettskaret 1, som vanligvis er delvis nedgrad i bakken, går det en avløpsrenne 5, som oventil for det meste er tildekket med plater i plan med resten av oppdrettskarets into a transverse water pipe 3 with openings 4 which ensure a more even distribution of the water in the breeding tank. Along the bottom of the rearing tank 1, which is usually partially downgraded to the ground, there is a drainage channel 5, which is mostly covered at the top with plates flush with the rest of the rearing tank
bunn, men som med visse mellomrom (2,5 m innbyrdes avstand har vist seg hensiktsmessig), er utstyrt med rister 6a-6f, slik at vann kan komme ned i rennen. Ved å dekke rennen med lokk vil bottom, but which at certain intervals (2.5 m spacing has proven appropriate), is equipped with grates 6a-6f, so that water can get down into the gutter. By covering the gutter with a lid will
vannet suges ned i rennen ved en form for sugeeffekt, og det oppnås en høy grad av fjerning av suspenderte partikler fra vannet i karet. I oppdrettskarets utløpsende, ved enden av rennen 5, føres vannet ut i en vannledning 7 med en regu-leringsventil 8, hvorigjennom uttatt vann ledes til et sedi-menteringsbasseng 9, hvori faste partikler, hovedsakelig for-rester, tillates å bunnfelle. Fra sedimenteringsbassenget 9 ledes avløpsvannet videre gjennom et rør 10 til en pumpekum 11, hvorfra det enten pumpes til en resipient gjennom et rør 12, eller gjennom en rørledning 13 resirkuleres til mate-ledningen 2 og innføres igjen i oppdrettskaret. the water is sucked into the gutter by some form of suction effect, and a high degree of removal of suspended particles from the water in the tub is achieved. At the outlet end of the breeding tank, at the end of the chute 5, the water is led out into a water line 7 with a control valve 8, through which withdrawn water is led to a sedimentation basin 9, in which solid particles, mainly residues, are allowed to settle. From the sedimentation basin 9, the waste water is led further through a pipe 10 to a pump sump 11, from where it is either pumped to a recipient through a pipe 12, or recycled through a pipeline 13 to the feed line 2 and introduced back into the breeding tank.
Litt under vannflaten i oppdrettskaret er det i oppdrettskarets 1 utløpsende anordnet en pumpe 14. Ved hjelp av denne pumpe kan vann fra avløpsrennen 5 føres inn i rør-ledninger 15a og 15b som fører til dyser henholdsvis 16a^-16a^og leb^-ieb,- som er anordnet i vertikale rekker som har innbyrdes avstand i oppdrettskarets lengderetning og som ligger i oppdrettskarets sidevegger. Dysene i hver vertikal rekke kan svinges i horisontalplan, hvorved deres stråleretning kan styres slik som antydet med piler i fig. 1. Dysene kan også svinges i vertikalplanet, hvorved de kan reguleres slik at deres stråleretning rettes oppover, nedover eller horisontalt ut i vannet i oppdrettskaret. I oppdrettskarets utløpsende kan det om ønskelig innføres oksygen i rørledningene 15a og 15b. Derved kan det gjennom dysene 16 innføres ekstra oksygen i oppdrettskaret, hvorved det blir mulig å regulere oksygenkon-sentrasjon relativt fritt og i varierende grad på forskjellige steder i karet. A little below the water surface in the rearing tank, a pump 14 is arranged at the outlet end of the rearing tank 1. With the help of this pump, water from the drainage channel 5 can be fed into pipes 15a and 15b which lead to nozzles 16a^-16a^ and leb^-ieb respectively ,- which are arranged in vertical rows that are spaced apart in the lengthwise direction of the rearing tank and which are located in the side walls of the rearing tank. The nozzles in each vertical row can be swung in a horizontal plane, whereby their beam direction can be controlled as indicated by arrows in fig. 1. The nozzles can also be swung in the vertical plane, whereby they can be regulated so that their beam direction is directed upwards, downwards or horizontally into the water in the breeding tank. At the outlet end of the rearing vessel, oxygen can be introduced into the pipelines 15a and 15b if desired. Thereby, extra oxygen can be introduced into the breeding vessel through the nozzles 16, whereby it becomes possible to regulate the oxygen concentration relatively freely and to varying degrees at different places in the vessel.
Fig. 2 viser et tverrsnitt gjennom oppdrettskaret 1 og viser dette nedgravd i bakken 17. Dyser 16a^ er i denne figur bare inntegnet i den ene sidevegg. Vanntilførselen (og den eventuelle ekstra oksygentilførsel) til dysene gjennom rør-ledningen 15a styres ved hjelp av en ventil 18 som reguleres ved hjelp av et ratt 19 over bakkenivå. Som det fremgår av figuren omfatter hver vertikal rekke av dyser (bare én, nemlig 16a^er vist) et antall dyser som er anordnet over hverandre. Dysene er forbundet med rørledningen 15a gjennom en gren-ledning 20 som går over i en fleksibel ledning 21 til hver enkelt dyse. Dysenes retning reguleres ved hjelp av en spake 22 som via en vertikal stang 23 er forbundet med en dyseramme som omfatter en øvre horisontal rammearm 24, som i sin ene ende er forbundet med den vertikale stang og en vertikal del 25 som oventil er forbundet med rammearmens 24 annen ende og nedentil er forbundet med en nedre rammearm 26. Den vertikale del befinner seg i avstand fra dysenes åpning, og gjennom denne rager det et dyseskaft 2 7 som går frem til dysemunningen. Ved løfting av spaken 22 føres den vertikale del oppover med det resultat at dysemunningen rettes nedover. Omvendt vil senking av spaken 22 bevirke løfting av den vertikale del 25, og derved blir dysemunningene rettet oppover. Dreining av spaken 22 i horisontalplanet bevirker svinging av dyseskaftene 27 i horisontalplanet og derved retningsforandring av vannstrålen i horisontalplanet. Fig. 2 shows a cross-section through the breeding vessel 1 and shows it buried in the ground 17. In this figure, nozzles 16a^ are only drawn in one side wall. The water supply (and any additional oxygen supply) to the nozzles through the pipeline 15a is controlled by means of a valve 18 which is regulated by means of a steering wheel 19 above ground level. As can be seen from the figure, each vertical row of nozzles (only one, namely 16a^ is shown) comprises a number of nozzles which are arranged one above the other. The nozzles are connected to the pipeline 15a through a branch line 20 which transitions into a flexible line 21 to each individual nozzle. The direction of the nozzles is regulated by means of a lever 22 which is connected via a vertical rod 23 to a nozzle frame which comprises an upper horizontal frame arm 24, which is connected at one end to the vertical rod and a vertical part 25 which is connected above to the frame arm's 24 other end and below is connected to a lower frame arm 26. The vertical part is located at a distance from the nozzle's opening, and through this a nozzle shaft 2 7 protrudes which goes up to the nozzle mouth. When the lever 22 is lifted, the vertical part is moved upwards with the result that the nozzle mouth is directed downwards. Conversely, lowering the lever 22 will cause the vertical part 25 to be lifted, and thereby the nozzle mouths are directed upwards. Turning the lever 22 in the horizontal plane causes the nozzle shafts 27 to swing in the horizontal plane and thereby change the direction of the water jet in the horizontal plane.
