BRIEF SUMMARY
This invention relates to a feeding installation, which handles feedstuff in the form of any feed and which is arranged as a floating module at sea.
In U.S. Pat. No. 4,372,252 a feeding installation is shown, which handles wet feed and which is arranged on land. There is employed a pump with associated pressure conduits for conveying a current of water centrally downwards through an upwardly opening feedstuff silo to a discharge at the bottom portion of the feedstuff silo, where the feedstuff is admixed with the current of water, the feedstuff being carried along in the water current and led via a transport conduit from the bottom portion of the silo to suitable feeding locations (fish pools).
In GE 2,000,421 a feeding installation is shown, which handles dry feed supplied from one or more separate silos, which are arranged in a module submersible in the sea, that is to say in a module submersible in the fish pool itself. The dry feed, for example in the form of feed meal, is dosed from the silo(s) via a valve arrangement directly out into the fish pool by means of compressed air.
In U.S. Pat. No. 4,799,459 a feeding installation is shown, which handles dry feed and which is arranged in a floating module at sea. The module comprises a feedstuff silo arranged centrally in the latter, which is connected below via a discharge opening to two separate feed openings to their respective separate transport conduits for distribution of feedstuff to their respective fish pools. The feedstuffs are pressed by means of a remotely controlled feed arrangement, which is arranged between the discharge opening and the feed openings, inwardly into and through respective transport conduits to the feeding location. The illustrated feeding installation is based on a fully automated operation, without a need for manual working or manual access to the feed arrangement. The module shown is adapted to be controlled as required in a variety of angular positions on the surface of the sea for the supply of feedstuff to different fish pools. However the module is badly suited for use at employment locations at sea exposed to the weather, where the module can be exposed to heavy wind and ocean forces in a relatively high floating feeding installation.
With the present invention the aim is a feeding installation of the afore-mentioned type, which is specially designed for employment at locations of use exposed to weather and wind, especially at locations along the coast towards the ocean, where the module can stand being exposed to heavy wind and ocean forces and can nevertheless be operated with great dependability, in a fully automated, remotely controlled manner known per se. More especially the aim is a module which exhibits favourable features at sea, having great stability, low weight and concentrated, favourable weight distribution in the module.
In addition the aim is a solution which gives easier access to vital parts of the feeding installation for inspection and possible repair, when this is necessarily required, even with feedstuff occupying the silo(s).
The feeding installation according to the invention is characterised in that the module has a vertical shaft, which is arranged centrally, surrounded by one or more feedstuff silo/silos, and that the silo/silos over a large portion of their height dimension have lower sidewall portions converging obliquely inwards and downwards, the shaft and the converging sidewall portions are terminated just above a feedstuff transfer hold at the bottom of the module, while module outside of the converging portions has an outer surface converging obliquely inwards and downwards.
According to the invention an advantageous internal arrangement is obtained in the module and in addition an advantageous external design of the module, so that the module can function effectively at sea even under severe weather and wind conditions. Inter alia a funnel-shaped outline of the silos is achieved internally in the module downwardly towards the feedstuff transfer hold, while in addition an equivalent fr
