The invention relates to fish farming technology, in particular to devices for growing and keeping fish in cages.

The aim of the invention is the convenience of operation and the prevention of injury to fish.

The proposed device allows creating a large cage volume, which provides an increase in the fish output per unit volume and at the same time has the ability to lift the cage ashore due to its folding and reducing the building height. This increases the output of marketable fish by improving the conditions for its development and growth, provides temperature and light conditions, water exchange, waste disposal, reduces the feed coefficient due to the increased survival rate of fish, and also improves the working conditions of the staff.

net canvas 11. The bottom 12 of the cone-shaped form has vertical walls 13 and is suspended on the core 14 to the frame 8.

Caisson feeders 15 are mounted on the upper part of the cage 3, and compressed air cylinders 16 are connected to the float valve 17 on the pontoon 1. The feeders 15 are equipped with a dispenser for periodic feeding (not shown). On the upper part of cage 3 there is a hinged eye 18.

The cone-shaped bottom 12 has a lattice drain hole 19, closed by a spring-loaded valve 20, which is flexible with a connecting rod 21, passed through the tank 3 and the sleeve 22, and is connected to the groove 23. The shutter 24 is designed to close the outside of the grating hole 21. hatches 25 with covers 26. On the outside of the vertical walls 13, guide plates 27 are fixed.

The free-hanging net-like web 11 is fixed on top of the tent part 9 of the cage 3, and at the bottom on the annular cross 28, which rests on the inner annular stop 29 located on the inner side of the vertical wall 13 of the bottom 12.

At half the height of the netting sheet 11, there is an elastic ringed elderly 30 having a diameter smaller than the diameter of the frame 8.

In order to hold cage 3 on pontoon 1, grips 31 are made on the upper part of frame 8, and support brackets 32 are made on pontoon.

In order to keep fish of various sizes in the cage, the internal part of the cage is divided into sections by vertical net walls 33 fixed on the spokes 34 of the annular belt 28, and on the bottom 12 there are opposing vertical ribs 35 in contact with the spokes 34 (FIG. 3).

On the pontoon 1 there are two hard sails 36, made in the form of two convex plates, placed at an angle of 90 ° one relative to the other (Fig.7),

The pontoon 1 has a cone-shaped hole 37 with a one-sided cut corresponding in shape to the cabaret part 9 of the frame 8.

The device works as follows.

Before installing the device, stationary measles 5 (Fig. 1) are lowered to the bottom of the reservoir, which is connected to the buoy 4 by a rope 6. Pontoon 1 is connected to the buoy 4 by a mooring rope 7. The submersible cage 3 is lowered into the water using a winch 2 and a rope fixed 18. The immersion depth depends on the state of the water surface, wave height, wind direction, as well as temperature and light conditions. The depth of ditch 3 is regulated in the process of growing fish by lifting winch 2 from pontoon 1 or remotely by cable from the shore.

With the help of sails 36 mounted on the pontoon 1, the device is moved into the water column than the natural water exchange in the charge is achieved when using the device in closed reservoirs.

With the wind effect of different directions on the sails 36, the device performs a circulation movement along the radius around the core 5 by an amount equal to the slack of the rope 6 with respect to the depth of the reservoir. In order to increase the efficiency of the sails 36, they must be given a two-convex shape, and in order to increase the possibility of using different directions of wind flows, the sails are positioned relative to each other at an angle of 90 °.

Fish are fed through caisson feeders 15, in which, depending on the depth of the cage, the appropriate pressure of compressed air from the cylinder 16 through the float valve 17 is maintained (Fig. 2). The control of the vibrating dosing unit of the feeders 15 is performed by remotely supplying an electrical impulse via a cable from a pontoon or from the shore from a timer.

The waste of fish in the process of their cultivation accumulates in the cone-shaped bottom 12 of the cage 3. Cleaning the bottom of the waste and water exchange in the cage 3 is carried out by vertical raising and lowering of the cage 3 with the help of a winch 2 with the open spring-loaded valve 20 through the grate drain hole 19.

Lifting cage 3 is carried out by a winch 2 (Figures 2 and 7), while the tent part

9 enters the cone-shaped notch of the pontoon 1.

If it is necessary to transport the cage to the shore, the raised cage 3 (figure 2) is fixed on the support brackets 32 of the pontoon 1

0 by the clamps 31. Then the hook of the winch rope 2 is disconnected from the hinged eye 18, and the mooring rope 7 from the floating bu 4. After that, the pontoon 1 is towed with cage 3 to the shore. To reduce towing resistance, the pontoon has zygomatic outlines in the direction of towing. Before lifting the cage 3 to the shore, in order to reduce the building height, it is folded down, for which the hook of the coastal lifting device is hooked onto the wheel

23, attached to the flexible pipe 21, wherein the guide plates 27 on the outer side of the vertical wall 13 enter the annular with 10, and the annular core 30 tightens the net 11, thus preventing the entanglement of the later and the injury of the fish ( 4). To maintain water in the bottom 12, when lifting the tank 3, the spring-loaded valve 20 is closed with the thrust 21. Then, the grippers 31 located on the tent part 9 are removed from the brackets 32 of the pontoon 1, and towed

 pontoon 1 from tank 3, while the tent part 9 of tank 3 passes through a cut-out in pontoon 1 (Fig.6 and 7).

With the approach of the folded tank 3 to the bank, the covers 26 of the hatches 25 on the walls 13 of the bottom 12 are open, thus reducing the lifting weight by lowering the water level in the bottom 12. Before lowering the dump 3 on the land, the shutter 24 is closed manually. With the release of the cockpit 23 and the gigi 21 from the shore-lifting means, the spring-loaded valve 20 opens again. After stopping the folded cage 3 on land (FIG. 5), the annular-by-up from 28 raises up and is fixed on the frame 8, the flexible rod 21 is separated from the lever of valve 20, the aged 14 are separated from the frame 8, that

allows you to separate the frame 8 from the bottom 12. After that, the hatches 25 are closed with lids 26 and water is added to the bottom 12 to reach the required level to carry out sanitation and sort the fish into three dimensional groups, for which the bottom is divided by vertical ribs 35 into three sections.
