(54) DEVICE FOR LIVING FISH TRANSPORTATION

The invention relates to the fishing industry, in particular to devices for transporting live fish on ships.

A device for transporting live fish, which contains a tank, made in the lower part in the form of a semi-cylinder, and a rotary perforated blade mounted on a horizontal axis in the center of the tank with the possibility of fixing the blade in the horizontal plane 13.

However, the capacity in the device when transporting live fish is used irrationally. It is impossible to transport the quantity of fish corresponding to its volume, as the fish, concentrating in its lower part, are in conditions that do not ensure its viability.

The purpose of the invention is the rational use of the volume of the container.

This goal is achieved by the fact that a device for transporting fish on ships, containing a tank, made in the lower part in the form of a half-cylinder, and a rotary perforated blade mounted on a horizontal axis in /

the center of the container with the possibility of fixing the blade in the horizontal plane, is provided with an additional blade mounted on the axis symmetrically main, while the blades have a rectangle shape in longitudinal section.

In addition, the walls of the container are formed from removable perforated sections.

15

The device for transporting live fish contains a tank 1, built into the hold 2 of the vessel 3, the tank 1 is impenetrable, and on its side wall 4 there is a loading hatch 5

20 and discharge hatch b. Inside tank 1, a container 7 is installed, the end walls of which are the front walls of tank 1. In the lower part of the tank 7, it is made in the form of semi-.

25 lindra 8, -in-sided there is a blade 9, having the possibility of rotation around the axis 10 passing through the axis of the axis of the half-cylinder 8, the blade 9 has a rectangular shape in plan. 30 Its sides are adjacent to the end faces.

the walls of the tank 7 have a length equal to the diameter of the half cylinder 8; secured by means of the batten 13 to the batten, made of T-shaped beams 14 and mounted inside the tank 1 (see FIGS. 1 and 2).

The blades 9 consist of a frame 15, which is fixed on the axle 10, and removable perforated sections (see Fig. 3. The frame 15 is made of pipes, all sections of the blades 9 and 11 are fixed by means of 16 with one side on the axis 10, the other on the frame 15, Elastic seals 17 are also reinforced on the frame 15 from the outside, made, for example, of rubber. To ensure the rotation of the blades 9 and 11, their axis 10 is connected to a pulley 18 located outside the front wall 19 of the tank 1 cm, 4, 4 on a pulley 18 is secured by a receiving cable 20, bred on a winch (not shown), on the p An ebord 21 of a pulley 18 is secured by a drive cable 20, which is connected to a drive bar. On a flange 21 of a pulley

18 holes 22 are made, on the wall

19 above the shaft 10, a hole (not shown) is also made, which is located at the same distance from the shaft 10 as the hole 22, Near the pulley 18 on the chain 23, the pin 24 is suspended, intended for fixing the blade in a horizontal position, position 25 at loading fish, position 26 when unloading fish and t, d, (cm, fig, 1),

In the lower part of the tank 1 under the perforated semi-cylinder 8 holey pipes 27 are placed for aeration of water in the tank 7, the pipes 27 are connected to the aeration system (not shown)

The device works as follows.

Before loading the fish, close the unloading hatch 6, open the loading hatch 5 and fill the tank 1 with sea water to the lower edge of the hatch b. The blades 9 and 11 with the help of a winch set at position 25 and fixed in this position. This is achieved by turning the pulley 18 until the corresponding hole 22 on the flange 21 coincides with a hole on the wall 19 (see FIG. 4), after which the tab 24 is inserted into both of these holes,

Next, through the hatch 5 load the tank 7 with live fish. After that, the blades 9 and 11 turn clockwise to install and then fix B to a horizontal position, thus dividing the capacitance 7 into two

parts. After that, load the live fish top. At the same time, the tank 1 is filled to the top with water. Then the hatch 5 is closed and a water aeration system is connected.

After the ship’s arrival at the port, hatch 5 is opened, the water level in tank 1 is adjusted to the lower edge of hatch b and the last one is opened. After that, the blades 9 and 11 are turned clockwise and placed in position 2b. Thus, the fish from the upper parts of the tank is concentrated at the hatch 6, through which it is discharged. Due to the presence of elastic seals 17 when rotating the blades 9 and 11, the formation of gaps between it and the surface of the half-cylinder 8 and, consequently, the injury of the fish, is prevented.

The blades 9 and 11 are then rotated by 180 ° and again fixed to position 26. This allows the fish to be concentrated from the bottom, the tank 7 at the unloading hatch 6. After that, the fish is unloaded.

The use of the invention will allow the most efficient use of the volume of the tank and increase the number of fish transported in comparison with the prototype.

In addition, since internal capacity 7 is filled out. perforated sections, the volume of water for transporting fish is increased in the proposed device to the volume of the external tank 1, It will also allow an increase in the amount of cargo transported.

The implementation of the tank 7 and the blades 9 and 11 of the removable sections provides easy access to any part of the device and, consequently, its quick inspection and cleaning,
