Description

one

The invention relates to fish farming, in particular, to a cage set itself, grouped from separate cages or cage sections, and can be used both for floating cage complexes and for complexes mounted on pile supports.

When conducting fish farming, it is important to have a sufficient number of tanks for carrying out various fish-breeding works in isolated volumes, in order to ensure the required density of fish planting and increase its salvage area, as well as for maintenance of the tanks in turn.

In fish farming, on the basis of construction structures such as pools, tanks, etc., the latter are performed with compartments or chambers equipped with openings with movable ceilings to communicate or isolate compartments to meet these requirements.

The Ieyesten cave complex for breeding fish, consisting of supporting float elements carrying flooring in vertically located guides, and mounted in the last cages joined together with each other, the end walls of which are made removable and installed with the possibility of movement in guides in a vertical plane.

However, the well-known cage complex does not provide an optimum link to the reservoir, since it creates a channel for fish breeding, and the area of the reservoir is not used rationally.

The aim of the invention is the possibility of changing the configuration of the complex and thereby ensuring the rational use of the area of the reservoir.

To achieve this goal, in the Sadakovo complex, consisting of supporting elements, carrying the flooring and vertically arranged guides, and mounted in the last cages joined to each other, the end walls of which are made

25 are removable and mounted for movement in guides in a vertical plane, the side walls of the cages are made and mounted similarly to the end, and the guides

30 supporting elements are fixed with the possibility of movement in the BepTHKanbuo plane. FIG. 1 shows a part of a floating cage device, a plan; in fig. 2 - the docking unit of the cage sections, section A-A in FIG. one; in fig. 3 - part of the collecting cage device, type B in FIG. one; in fig. 4 - installation unit for fixing the flange of the cage sections, section B-B in FIG. 3; in fig. 5 — unit for installation of the clip holder, section G-D in FIG. 3 in FIG. 6 - side view of the collecting cage device on the piles; FIG. 7 - cage device general view in plan. The cage complex contains the joints of interconnected cages 1 fixed to the supporting float elements 2. Cages 1 can be made of net material with or without a rigid frame. They can also be made in the form of chambers and rigid sheet material, for example, plastics. The cages can be fitted with upper ceilings to provide the necessary level of illumination or to protect young fish from birds. All tanks 1 have removable walls and are installed in vertically arranged guides 3, behind supporting elements 2 fixed along the perimeter. Guides 3 are made in the form of flanges 3. The walls of the cages are made in the form of a barrier 4, which can be made as solid partitions rigid sheet material or in the form of a frame with a lattice, mesh, or overlapping of the plies made of flat material. At the same time, the upper part of the barriers 4 has a protrusion 5 extending along their upper edge, by means of which the barrier 4 clashes with the flange 3. Instead of the barrier 4, a frame with an open opening can be installed, similar to the barrier frame. Another embodiment of the flanges and barriers is possible, in which grooves are made in the flanges and barriers are inserted into them with a seal with the latter being displaced vertically (not shown). Element 2 of the floating cage complex is formed from separate base parts 6 with four corner sockets 7, representing in plan a square, the side of which is equal to 1/2 the length of the charge (Fig. 1). At the corner of Btox. The nests 7 are installed and fixed floats 8 (Fig. 3). The corner sockets 7 on the outer side have flanges 9, through which the parts 6 are rigidly connected to each other. For this purpose, the flanges 9 have holes 10 (Fig. 1) in which a rod bolt 11 is installed (Fig. 1, 3). Parts b can be made under one tank or several cage sections. On the corner slots 7 of the basic parts laid flooring 12 (Fig. 1.3). The parts 6 have guides 13 which interconnect the sockets and are located at the inner corners of the sockets 7 so that they are separated from the holes 10 at a distance equal to 1/2 of the length of the charge. In the guides 13, the clips 14 are mounted with two parallel grooves 15 (Fig. 1). The width of the grooves 15 is equal to the sum of the thicknesses of the flange 3 and the barrier 4 or its frame (Fig. 2). This provides a tight-fitting installation in the grooves 15 of the flanges 3 with barriers 4. The flanges 3 with barriers 4 can be moved in the vertical direction and held at the desired height relative to the yoke using a rod lock 16 fixed on the chain 17 and installed through the socket 18 in the cage in one of the sockets 19 of the flange 3 (Fig. 4). The sleeves 14 can move in the guides 13 of the element 2 in the vertical direction and be held at the desired height relative to the guides by means of a clamp 20 attached to the chain 21 and having the ability to install coaxial axes 22 of the guides 13 and one of the holes 23 of the yoke 14 (Fig. 5). On the pile supports 24 (Fig. 6), the guides 13 of the basic parts b are fixed, and to them the frames 25 for floorings. Barriers 4 (Fig. 7) are installed in accordance with one of the stages of the production cycle. The floorings 12 are laid in a line, the transition from line to line is provided by means of transitional ladders 26. During the construction of the floating cage complex, the base parts are joined to each other using the flanges 9 of the sockets 7, and the connection is fixed by a rod lock 11. In this case the distance between adjacent pairs of guides 13 should be equal to the length of the cage sections. Further, the sleeves 14 are inserted into the guides 13, and in turn, flanges 3 with barriers 4 are installed. The cage complex of the required configuration can be mounted in one stage, but can be mounted in several stages as the working height increases. volume. In this case, the pile supports 24 can be installed in advance, based on the maximum development of the structure of the cage complex, and can be installed when performing the next stage of development of the structure of the cage complex. If necessary, replace one or more cage sections 1

fish from them at open barriers 4 are distilled into adjacent sections, and then the barriers of adjacent sections overlap their openings and the sections to be removed are removed from the water. Cages 1 can be taken out and together with the fish contained in them. Removed from the water cages can be easily cleaned or repaired. In addition, cages can be replaced with cages of other functional purposes, in particular, cages for the medical treatment of fish, spawning or hatching cages, sorting, feeding, for the production of live food, etc.

If it is necessary to change the depth of individual cage sections, their flanges 3 raise to the desired height relative to the yoke 14 and lock up in this position using clamps 16. If you need to change the depth of a group of adjacent cages, lift the yokes 14 into the guides 13 and fix them in this position using latch 20.

If necessary, communicating or separating adjacent cages, respectively, raise or lower the barriers 4. If the barriers are removed, then to ensure sufficient sealing between the flanges 3 and the yokes 14 (Fig. 6.7), instead of the barrier 4, it is necessary to insert frames with an open inner part identical to the barriers. By manipulating with barriers 4 and cages 1, it is possible to ensure the creation of various forms and volumes of space for fish or to ensure its concentration in a certain zone (Fig. 7). In this case, it is possible to ensure the creation of a closed circuit for the circulation of fish for its movement in different directions along an endless channel (Fig. 7).

As follows from the above, the proposed prefabricated cage complex

provides the possibility of replacing the cage sections and their docking without overloading the fish, which allows changing the functionality of the cage complex and carrying out its maintenance without stopping the production process. In addition, the proposed cage device, without any installation operations and without overloading the fish, allows the volume and configuration of the space in which the fish are contained to change, in particular to increase it or, conversely, to ensure the concentration of fish in the desired area. The universality of the proposed precast cage complex and the convenience of its maintenance is achieved with a high degree of unification of such cage complex. All this allows to obtain a significant technical and economic effect.
