Abstract

Aquafeeder bringer vann og kommersielt fôr fra overflaten og ned gjennom hovedrør (3) til ønsket dybde, uten at fôr eller vann er tilgjengelig før det spres ut gjennom forgreiningsrør (7) i ønsket dybde. Fôret føres ved hjelp av hovedrør (3) og forgreiningsrør (7) ut i ønsket dybde. Pumpe (5) som skaper undertrykk ved hjelp av en ejektor plassert i fordelingskammeret (4), sørger for sirkulasjon og av vann og fôr i Aquafeeder. Vann tilføres Aquafeeder og fører vann og fôr ut ved tilnærmet samme dybde for å unngå å tilføre vann fra de øvre vannlag til de nedre vannlag. Begge rør (8) for inntak av vann er forsynt med en sil for å unngå større fremmedlegemer. Bunnring (6) omslutter fordelingsrørene ved utløp og er fylt med vekter for stabilitet.Aquafeeds bring water and commercial feed from the surface down through the main pipe (3) to the desired depth, with no feed or water available before spreading through the branch pipe (7) at the desired depth. The feed is guided to the desired depth by means of main pipe (3) and branch pipe (7). Pump (5) which generates negative pressure by means of an ejector located in the distribution chamber (4), ensures circulation and of water and feed in the Aquafeeder. Water is fed to Aquafeeder and carries water and feed at approximately the same depth to avoid supplying water from the upper water layers to the lower water layers. Both pipes (8) for water intake are provided with a strainer to avoid larger foreign matter. Bottom ring (6) encloses the distribution pipes at outlet and is filled with weights for stability.

Description

Beskrivelse Description

Oppfinnelsen angår en teknisk løsning for å tilføre ordinært kommersielt anvendt fiskefdr ut i vannmassene i ønsket dybde fra overflaten, uten at vann fra de øvre vannmasser tilføres de lavere vannmasser. The invention relates to a technical solution for supplying normally commercially used fish feed into the water masses at the desired depth from the surface, without water from the upper water masses being supplied to the lower water masses.

Dette skal gjøres uten at fåret er tilgjengelig for laksearter, eller andre fiskearter som går pelagisk i oppdrettsmerd eller kar før foret befinner seg på ønsket dybde. This must be done without the feed being accessible to salmon species, or other fish species that go pelagically in breeding pens or vessels before the feed is at the desired depth.

Det er en utfordring for, blant annet, oppdrettere av laks at fisken oppholder seg forholdsmessig mye i de øvre vannlag i forbindelse med foring. Noen av disse utfordringene kan reduseres ved at foret tilføres på dypere vann. It is a challenge for, among others, salmon farmers that the fish spend a relatively large amount of time in the upper water layers in connection with feeding. Some of these challenges can be reduced by feeding the feed in deeper water.

Oppfinnelsen sørger for at foret ikke blir tilgjengelig, ved å føre foret fra overflatenivå i et foringsrør til ønsket dybde. I enden av røret er det et forgreiningssystem som sørger for at foret blir fordelt i et sirkelmønster. The invention ensures that the lining does not become accessible, by leading the lining from surface level in a casing to the desired depth. At the end of the tube there is a fork system which ensures that the feed is distributed in a circular pattern.

For å unngå å føre overflatevann ned i vannmassene, suges vann fra tilnærmet samme dybde som foret føres ut i vannet, til øverst i foringsrøret. To avoid bringing surface water down into the bodies of water, water is sucked from approximately the same depth as the casing is brought out into the water, to the top of the casing.

Ved å benytte en pumpe blir vann ført inn i fordelingskammeret og gjennom en ejektor som skaper undertrykk ovenfor fordelingskammeret. Det er dette undertrykket som sørger for at vann suges fra dypt vann og opp til den øverste delen av røret. Begge inntakene er utstyrt med en sil for å unngå større fremmedlegemer. By using a pump, water is fed into the distribution chamber and through an ejector which creates negative pressure above the distribution chamber. It is this negative pressure that ensures that water is sucked from deep water up to the upper part of the pipe. Both intakes are equipped with a strainer to avoid larger foreign bodies.

Oppfinnelsen er tilpasset dagens tilføringssystem av for til merdene. The invention is adapted to today's supply system of lining to the cages.

Claims

1. Aquafeeder (the name of the patent claim) commercially supplies feed from sea level to the desired depth so that the feed is not available until the feed is released at the desired depth.

2. Aquafeeder according to claim 1, characterized in that the feed is fed through pipes from sea level using negative pressure created by an ejector placed in the distribution chamber (4).

3. Aqufeeder according to claim 1, characterized by float collar (2) keeps Aguafeeder afloat. The float collar (2) is squarely designed with tubes with attachments for the main tube (3) and keeps the Aquafeeder floating on the sea surface (1)

4. Aquafeeder according to claim 1, characterized in that the main pipe (3) leads and water down the main pipe (3) is spread out via the branching pipes (7). The tubes are cylindrical in shape.

5. Aquafeeder according to claim 1, characterized in that a negative pressure is created by means of an ejector which is placed in the middle of the distribution chamber (4), the ejector is driven by a pump (5) which receives water from a pipe with a strainer (8). The negative pressure created by pumping water through the ejector creates a negative pressure that sucks water from the pipe with strainer (8) into the main pipe (3) just below the water surface.
