DESCRIPTION:
BRIEF SUMMARY
The object of the invention is to provide a method of the present type which enables rapid and easy emptying of a tank of fish.
This object is achieved by moving a net-shaped scraper means having a width corresponding to the distance between two adjacent partitions so that its outer edge substantially follows the inner side of the hull with constant change in the angle formed by the scraper means with the vertical plane. Thus, by performance of a single movement through the entire tank the scraper means pushes all the fish ahead of it so that during the last part of the movement all the fish are brought up to the upper edge of the hull from where they can be poured directly down into a cage or down into a net or a bucket from where they can then be poured down into the cage.
A more rapid and rational way of transfer is stated in claim 2. Thus, the fish are flushed through the hose
A more rapid and rational way for transferring of the fish is disclosed by the present application. According to the invention, the fish can be flushed through the hose directly down into the cage.
The present invention provides a particular simple design of the barge, so that the movement of scraper means is simple rotation about a fixed axis.
The present invention provides a structure which is in addition to making the barge stable, provides convenient way of temporary attachment of a hopper with a hose for transferring of the fish to a cage. A pump with a flushing hose for the same purpose is provided. Both the flushing hose and the hopper can readily be moved from one tank to another.
The present invention also provides an arrangement which enables scraper means to be moved from one tank to another, so that common scraper means may be used for all the tanks.
A simple construction of the attachment means for the hopper is also disclosed by the present invention.
A simple embodiment of the attachment means for the hopper is stated in claim 8.
One end of an embodiment of the barge of the invention is shown cut transversely in the drawing and will be described more fully below with reference to the drawing.
In the drawing, the barge hull is generally designed by 10. This hull has a relatively narrow, plane centre bottom part 11 and two hull parts 12, which are quarter-circular in cross-section and along whose upper edge a hollow floating member, substantially rectangular in cross-section, extends. The plane bottom part 11 forms one side of a box-shaped central part 14 whose upper side is coplanar with the upper edge of the hull and forms a footbridge 15 between two decks 16 above the rounded ends of the hull.
The spaces between the central part 14 and the hull are divided into a plurality of tanks 18 of the same size by transverse partitions 17. The front and the rear partitions 17 close the spaces between the decks 16 and the hull. These end spaces are accessible through hatches 19 in the decks and are used for storing various equipment, such as e.g. oxygen cylinders for oxidation of the water in the tanks.
Two upwardly open bearings 20 of semi-circular cross-section are attached to the upper edge of the central part 14, in alignment with each tank 18. Each pair of these bearings accommodates the upper frame member 21 of a rectangular frame 22, which may e.g. consist of stainless steel tubes, and in which a wire net 23 is stretched. This frame with wire net forms a scraper means which has approximately the same width as the tanks and extends, in the position shown in the drawing, right down to the bottom of the hull, with the exception of a small clearance. The side frame members are extended upwardly and interconnected by a transverse member forming a handle 24.
Two brackets 25 of rectangular cross-section are attached to the upper side of the floating member 13, in alignment with each tank 18. The brackets serve to receive flat, rearwardly extending fingers 26 of a Z-shaped cross-section, which are attached to the underside of a hopper 27 with a rectangular mouth facing obliquely downwardly toward the tank and with a pipe conn
