Description

The utility model relates to fish farming, namely to cages for commercial fish farming, and is aimed at improving the conditions for keeping fish and their maintenance.

Known fish tank ASF-30PL [1], containing the pontoon part, the rail part with a network camera fixed to it.

The network camera of the device does not provide good conditions for keeping fish, as well as comfortable access to it for various manipulations (routine inspection, sorting, selection of individuals, etc.), especially when working with large individuals.

Known cage for the industrial cultivation of fish with artificial aeration [2], a net camera which does not exclude the above disadvantages.

The production cycle of commodity cultivation of valuable fish species (sturgeon, salmon) includes the formation of uterine stocks, the maintenance of large masses of fish. The period of keeping fish under these conditions is quite long and requires constant monitoring of individuals. Cage devices for these purposes should provide constant comfortable access to fish for various manipulations with it.

The technical goal of the developed utility model is to expand the biotechnological capabilities of the cage device, while at the same time creating favorable conditions for both keeping fish and the possibility of various manipulations by specialists.

This goal is achieved in that the fish tank includes a sectional floating frame (1) with a deck (8) and a guard rail (2) and a cage chamber (3) made of stainless steel chain mail (4) with a rigid frame bottom (5), chain mail the web (4) is made of rings with a diameter of 57 mm to 127 mm, of wire with a diameter of more than 2.5 mm, while the rings are not fixed to each other in a rigid coupler, and the bottom is a frame made of pipes onto which rods 10 mm thick are welded forming a mesh size of 150 × 150 mm. and equipped with pontoons from welded pipes PDN, which are fixed in the flooring.

A general view of the cage is shown in FIG. one.

The design of the cage includes: 1 - sectional floating frame, 2 - railing, 3 - cage, 4 - stainless chain mail, 5 - rigid frame bottom, 6 - winches for raising the bottom, 7 - pontoons of the bottom frame, 8 - flooring, 9 - feed dispenser, 10 - security system, 11 - surface security fence of the cage.

The frame (pos. 1) and the bottom (pos. 5) are assembled from 8 or more sections (pos. 12, pos. 13, respectively) depending on the required diameter of the cage.

In FIG. 2 shows a view of the frame bottom assembly.

In FIG. 3 shows a view of the cage with the raised bottom.

In FIG. 4 shows a view of a stainless steel chain cloth on a bobbin.

The bottom is moved by hand winches (pos. 6), and to facilitate it, whose weight is 1550 kg, welded HDPE pipes are used, which are driven and fixed in the bottom frame.

Corrosion-proof chain mail excludes rotting, fouling, gusts (gnawing) and fish leaving the cage. Its vibrational movements (vibrations) and sufficient throughness provide additional water exchange in the cage and reduce the effect of the enclosed space, which increases the comfort of the fish staying in the cage for a long time. Chain mail does not take the load on a separate section, but on the entire surface of the canvas. Mobility (folding, unfolding, lifting, lowering) of the chain mail is provided by rings with a diameter of at least 57 mm from a wire with a diameter of more than 2.5 mm, which are not fixed to each other in a rigid coupling.

A fish tank with a stainless steel chain mail (net) is made, assembled and operated as follows.

For the manufacture of chain mail using a stainless wire with a diameter of at least 2.5 mm, for example, from material 12X18H10T GOST 18143-74. Ring mail rings are made with a diameter in the range of 57-127 mm.

A stainless wire is connected with argon-free solder, argon-free solder, and laser contact welding. The method of connecting rings is selected depending on its size, wire thickness, strength characteristics of the fabric assembly, as well as the availability of appropriate equipment.

Rings are made, for example, by argon-free soldering without a solder, by a non-combustible electrode in an argon medium. Two ends of the wire are melted, which are joined using a crimping device. Get rings that are woven with standard weaving 4 to 1. One ring in the middle, four from the edge. A web of 4 or 3.5 m wide and 50 m long is obtained. Then the initial and last rows are sewn together, and a circle of chain mail is obtained. The finished fabric is wound on a bobbin, and sent to the farm, where they install a cage.

A sectional floating frame is assembled from 8 sections, on the railing of which a ready-made circle of chain mail is attached, and a bottom is attached to the lower edge.

The bottom frame is assembled from three contour pipes, which are connected to a triangular truss. The truss sections form a circle of large diameter, onto which floor-type shields are welded from a strip of 40 mm with a cell size of 300 × 300 mm. Using the tension cable, a netting net of 2 mm wire is installed in the bottom frame. Get the surface on which to put the del feed table.

To control the fish and perform various manipulations with it, the bottom of the cage is raised, for which 4 manual winches are used. The bottom is facilitated by pontoons from welded PDN pipes, which are driven and fixed in the bottom frame.

The rigid construction of the bottom in a raised state provides comfortable conditions for both staff and farmed fish at the time of observation, control and other manipulations with them.
