DESCRIPTION:
BRIEF SUMMARY
The invention relates to a plant for fish farming in the open sea, comprising a net-work container submerged into the water, and elongated hollow bodies floating on the water, from which said container is suspended.
Prior art plants of this kind are of a construction which does not allow the plant to be used in water regions where large wave movements may be expected, because there is a risk that the plant will be broken down when such large wave movements are encountered.
The purpose of the invention is to provide a plant of the kind referred to above which is suitable for water regions wherein large wave movements may be expected so that the fish farming can be carried on in such regions of the ocean far from land where the water is of a higher quality and where the influence from the environment is less concentrated.
In order to achieve this object the plant of the invention has obtained the characteristics appearing from claim 1.
In order to explain the invention in more detail reference is made to the accompanying drawings in which
FIG. 1 is a perspective view of a fish farming plant of the invention in a preferred embodiment thereof,
FIG. 2 is a fragmentary plan view of the plant in FIG. 1,
FIG. 3 is an enlarged cross-sectional view of two hollow bodies connected together to form a floating unit,
FIG. 4 is a plan view of the connection between two floating units,
FIG. 5 is a cross-sectional view of the connection shown in FIG. 4,
FIG. 6 is an axial sectional view of a joint provided in a protective railing,
FIG. 7 is an axial sectional view of a joint for interconnecting platforms supported by the hollow bodies, and
FIG. 8 is an axial sectional view of a connection between a platform and a hollow body.
With reference to FIGS. 1 and 2 the plant for fish farming in the open sea shown therein comprises a number of elongated closed hollow bodies 10 of rubber or plastic material, which can be substantially shape permanent but also can comprise inflatable hollow bodies which may be filled with balls or similar bodies of a light plastic material so as to be kept floating even if the body should be punctured. In the preferred embodiment, the hollow bodies are made of lengths of cylindrical rubber tubing, which are closed at the ends by the tubing being flattened and the flat portions thereof being interconnected by gluing or vulcanization.
The bodies 10 are interconnected in pairs with the bodies of each pair extending in parallel, spaced one beside the other to form floating units. The connection between the bodies of each unit is shown in more detail in FIG. 3 to which reference now is made.
Between the two bodies 10 of each unit there is provided a spacer 11 forming two opposite circular recesses 12 each receiving one of the hollow bodies 10. On top of each tubular body there is provided a spacer 13 also formed with a circular recess 14 to receive the associated body therein, and a tube 15 having square cross-sectional form is located on top of the three spacers 11 and 13. The spacers form aligned grooves to receive the tube 15 therein, and the tube projects at each end from the spacers 13. In a lug 16 connected to the tube 15 at each projecting end portion thereof a strap 17 is connected at the end thereof and extends around the two hollow bodies 10 of the unit. The strap preferably is received in a groove formed by the lower surface of the spacer 11. The strap 17 can be tightened by fitting the strap around the hollow bodies stretched around said bodies and then pressurizing the interior of the hollow bodies so as to engage the wall thereof against the strap and thus tightening the strap around the bodies. A tube 18 is connected to the tube 15 perpendicularly to the lower side thereof and is received in a bore 19 in the spacer 11 to center the tube 15 in the floating unit.
The floating units formed by the interconnected hollow bodies 10 are each interconnected at the ends thereof by universal joints 20 to form a closed configuration, viz. in the embodiment described a hexagonal configuration as is best
