Description

This invention relates to fish farming equipment, in particular, to railway equipment for growing fish in cages.

A known plant for growing fish, containing cage sections, is concentrically mounted and connected to the vertical axis with the possibility of rotation in a horizontal plane, the cages being fixed on concentrically arranged pontoons, and one of the cages sections is provided with a propeller, while the central one is rigidly fixed on the vertical axis. a pontoon and a platform above the cages, which is connected to the central pontoon through an additional annular pontoon and has openings for each ticipate technological operations 1.

The design of this device adversely affects its wind resistance, which prevents the device from being used in open waters. In addition, the device uses only a small layer of water vertically, and this worsens the temperature of the water and does not allow the fish to choose the desired temperature horizon itself.

The closest technical solution, chosen as a prototype, is a device for growing marine organisms, in particular fish, consisting of a vertical cylinder with buoyancy, on which inflatable tanks are mounted, with containers located around a vertical cylinder approximately in a horizontal plane and associated with vertical cilin-. the cores of the rods, inside of which the water supply pipelines are installed, the containers in the plane have a circular shape and are connected to the rod by its central part or as close as possible to it, in addition, the central part of the tank consists of a pipeline leading to the central cylinder, and a valve on the outside 2.

The supply of this device with fish feed, fuel, fresh water is difficult. In addition, the disadvantage of this device is the unstable position that is created when it is in the submerged position.

The aim of the invention is ease of operation, as well as an increase in submerged stability.

The goal is achieved by the fact that a device for growing fish, containing cages with feed dispensers connected by brackets with a variable buoyancy pontoon, mooring barrels and measles, is provided with

mounted on a pontoon variable buoyancy mast with a ramp, while the ramp is mounted on the mast can be rotated in a vertical plane, and

its free end is provided with a floating support; in addition, the brackets are attached to the pontoon with variable buoyancy that can be rotated in the vertical and horizontal planes.

0 Comparative analysis with the prototype allows us to conclude that the device described differs in that it is equipped with a ramp mast mounted on the pontoon variable

5, the ramp is mounted on the mast rotatably in a vertical plane, and its free end is provided with a floating support; in addition, the brackets are fixed on the pontoon of the variable buoy of honor with the possibility of rotation in the vertical and horizontal planes.

FIG. 1 shows the proposed device, top view; in fig. 2 - connection of the tank with the buoyancy variable pontoon;

5 in FIG. 3 - device afloat; in fig. 4 - device at the initial moment of immersion; in fig. 5 - device in the submerged position; in fig. 6 is a diagram of the acting forces on a variable buoyancy pontoon located in a submerged position.

The device for growing fish contains netting 1, feed dispensers 2, variable buoyancy pontoon 3, mooring barrels 4 and measles 5. All netting 1

5 are made with a frame consisting of the upper tent part 6, the middle part formed by the vertical rods 7 and the lower part 8. On the upper deck of the pontoon 3 of variable buoyancy, the tower is mounted 9, the top tent parts 6 of the tanks 1 are attached to the feed dispensers 2 connected brackets 10 with pontoon 3 variable buoyancy with the possibility of rotation in the vertical and horizontal

5 planes The brackets 10 are provided with upper 11, lower 12 and 13 side braces. The upper straps 11 are passed through the blocks 14 and fixed on the mast 9. The lower 12 and lateral 13 straps are fixed on the hoop 3 of the variable buoyancy. On the mast 9 is fixed with the possibility of rotation in the vertical plane of the ramp 15, the free end of which is provided with a floating support 16.

5 When the device is afloat, the ramp 15 is used as a berth for ships supplying the device with feed, sources of electricity, and as similar along which cargo is delivered to pontoon 3 of variable buoyancy. In addition, the ramp 15 with a floating support 16 on the free end provides increased stability of the device when it is both submerged and afloat.

In the pontoon 3 of variable buoyancy, a tank 17 of the ballast system, cylinders 18 of compressed air, a feed bin 19, an automatic feeding system 20, a source of electrical energy (not shown) are located. The remote control of the ballast system is installed on one of the mooring barrels 4.

Feed dispensers 2 are made in the form of caisson chambers, each feed dispenser 2 is equipped with lighting (not shown) and level sensors (not shown) to maintain the level of the free surface of the water. Using hoses and cables, feeders 2 are connected to compressed air cylinders 18, a source of electricity (not shown), an automatic feeding system 20 located in the pontoon 3 of variable buoyancy.

Net cages 1 in the lower part have facilities for collecting and disposing of waste, dead fish (not shown).

Mooring barrels are connected by 4 with ropes 21 to brackets 10, and with the help of broods 22 to cortex 5.

The described device operates as follows.

Before installing the device for growing fish, measles 5 is laid on the bottom of the reservoir, which are connected with the mooring barrels 4 with the help of windmills 22.

Feed dispensers 2 are connected by hoses and cables to pontoon 3 of variable buoyancy. Stockpiles of feed, compressed air are replenished, charged with electric power sources, a program of an automatic feeding system is established.

Then the device is transported to a specified point in the sea. After the device is installed at a given point on the sea surface, the mooring barrels 4 are connected by ropes 21 to the brackets 10. The length of the ropes 21 is set equal to the immersion depth, which depends on the magnitude of the water surface, temperature and light conditions.

The device is immersed by means of a remote control of a ballast system, the console of which is installed on one of the mooring barrels 4.

When the ballast system tank 17 is filled under water, the device is submerged to a depth determined by the length of the ropes 21. And the ramp 15 is due to the floating

The support 16 occupies a vertical position.

When the device is in a submerged position, the pontoon 3 of the variable 5 buoyancy, which is in equilibrium, is affected by the force of gravity P applied to the center of gravity of the CG with the Zg applicator, the strength of the buoyancy Q applied to the center of the CG value with the applied Zc and force the amplitude of the F of the ramp 15 applied to the CR point with the applicator Zf.

At equilibrium of a pontoon with 3 variable buoyancy, the sum of the forces acting on it is zero. The sum of the moments of these forces in 5 this case is also zero.

When nakrenekii pontoon 3 variable buoyancy at an angle and there is a restoring moment Mvos equal to the sum of the moments of forces acting on the pontoon 3 0 variable buoyancy - P, Q, F.

Bridge Mp + MQ + Mp, where Mp is the moment of strength of body of tin P;

MQ is the moment of buoyancy force Q;

MF moment buoyancy force F; 5 Mr Ra;

Mo Q-a;

,

where is the vulture shoulder P and Q; C, - shoulder strength F.

0 Since, when the device is tilted, the buoyancy force F of the ramp 15 appears a shoulder Q, which has a larger value, the moment of force F (Mp) significantly increases the restoring moment (Bridge), and consequently, increases the stability of the device that is submerged .

The feeding of fish is carried out according to the established program of the automatic feeding system 20. For collecting and removing

0 waste, dead fish use the fixture located at the bottom of the cages (not shown).

When the device is lifted to the surface using a remote control, 5 the ballast system flushes its tank 17. After this, the device floats to the surface. At this time, replenishment of feed, compressed air is made, the source of electric power is charged, and mechanisms are inspected.

The proposed device in comparison with the prototype has great ease of operation and increased stability when the device

5 submerged.
