Description

 The invention relates to a device for storing an array of fish catch in the sea and can be used for mass fishing with a large number of fishing vessels in a limited area of capture or in stand-alone fishing in a large area.

 A device for growing fish is known, which contains a container for accommodating fish (or its fry), a floating device that is connected to the tank. The tank is equipped with a feeder.

The disadvantages of the described device is:
- the impossibility of quick loading, unloading and loading of the catch;
- placing the feeder on the tank itself does not allow changing the recharge in accordance with the changing storage time of the fish array, which also changes.

 These shortcomings do not allow it to be used to store fish catch in the sea. It is also difficult to store the described device on a ship.

 A device for preserving a fish catch is known, which is made in the form of a fish tank made of flexible material with holes that communicate with the aquatic environment.

 The specified fish tank is connected by a channel to the fishing gear through a pump, which provides transportation of the fish mass from the fishing gear (purse seine) to the storage tank.

 The tank itself, due to the material from which it is made, has positive buoyancy. The capacity is connected to the vessel, as well as to the means of fishing.

The disadvantages of the described device are the following:
1. In fact, the tank plays the role of a barge and additional energy is required for its transportation.

 2. Such a container should not be used for waves at sea, as it will be subjected to destructive effects from waves. This is due to the fact that the container is located on the water surface.

 3. If the aquatic environment is disturbed (even if the container is not destroyed), the catch will die due to the forceful effects of the waves on the catch, which is in a confined volume.

 4. The storage of the catch is very limited in time, since not every fish can be in the upper layer of the aquatic environment for a long time, which does not always correspond to the habitat.

 5. The catch is constantly affected by the flow of running water through openings in the wall when the vessel is moving, and this leads to the death of the fish.

The purpose of the proposal is to address these shortcomings, namely:
- increase ease of use;
- improve storage conditions;
- promptly change the depth of placement of an array of fish.

 The goal is achieved by the fact that the device for storing fish catch in the sea is equipped with a winch mounted on a floating vehicle, a fish life support system and a protective cover, and a device for linking the tank with the floating tool, the pump is also placed on the floating tool, the latter is made in the form of a sealed container with a vertical channel, the fish tank consists of a frame containing at least two horizontal belts, each of which is made in the form of a closed ring, and a net web in the form of a pipe fixed to The bottom, bottom and top of the fish tank are equipped with a cargo and a pipe with a hollow ring and a cap fixed to the pipe, respectively, and the device for connecting the tank with a floating means is a cable, one end of which is attached to the pipe cover and the other is fed to the winch, while the supply lines of the life support system are made flexible, some of their ends are fed to the winch for movement along with the cable, and the others are inserted through the lid into the fish tank.

 Figure 1 shows the device Assembly in the working position; figure 2 - floating means (hereinafter platform); figure 3 is a view along arrow A from above on the winch; figure 4 is a schematic diagram of a life support system; in FIG. 5 - the upper part of the tank for fish and its connection with the platform; in FIG. 6 - fastening to the belt of the upper part; figure 7 - cargo securing to the bottom of the fish tank; Fig. 8 is a view of a fish tank during storage.

 The device contains a platform 1, which is made in the form of a sealed container with a vertical channel 2. On the platform 1 is a winch 3, which has three pulleys 4, 5, 6 with guide rings on the jumpers 3-1, 3-2 and three drums 7, 8 9. In drums 7 and 9 are placed cylinders 10 with gas under pressure and a chamber 11 with a nutrient mixture, which form a life support system for the array of stored fish.

 The cable 12 and the trunk 13, 14 are collected by a ring 15, which is placed along the axis of the channel 2. The winch 3 has a vertical axis 16, and the drums 7, 8, 9 are equipped with a handle 17.

 A pump 18 with nozzles 19 and 20 is located on the platform 1. The pump 18 is located on the rotary table 21. The winch 3 and table 21 have position locks that are not shown conditionally. At the bottom of the platform 1 there is a load 22 and a guide cone 23, which provide a stable position of the platform 1 by shifting the center of gravity into the aquatic environment. All devices that are located on the platform 1 are closed by a rotatable protective cover 24. The cable 12 is connected to the cover 25, and the lines 13 and 14 through the holes in the cover 25 enter the internal cavity of the fish tank 26.

 The cover 25 is connected to a pipe 27, which has a hollow ring 28 and cutouts 29, into which pins 30 located on the platform 1 can enter. The cutouts 29 are either small in size or are closed by a shutter. A load 32 is placed in the bottom 31. The top 33 and the bottom 31 are equipped with a nylon mesh that is mounted on the ring 34 on bolts 35 between the ring 34 and the plate 36 on the pipe 27 and on the load 32, the upper and bottom parts 33 and 31 are secured with clamps 37 , 38.

The canvas 39, which is made in the form of a continuous pipe, is also attached to the ring 34. The ring 34 with the fastening fittings form horizontal belts. The chamber 11 is connected to the cylinder 10 through pressure reducers 40, 41 and have an adjustable throttle 42. Highways 13 and 14 have valves 43 and 44. The blade 39 is expedient to be made continuous with the following message:
1. The fish will be less damaged in an uncontrolled collision or stuck in the side surface.

 2. The more directed will be the flow of water when pumping fish out of the tank.

 3. The life support system will be used more effectively.

 At the same time, the implementation of the upper and bottom part 31 of the mesh material is sufficient for the circulation of water.

 The device operates as follows.

 Capacity 26 is collected in advance and stacked on deck (Fig. 8). Ring 34 is formed by unwinding a strip from a roll. The strip of the ring 34 has holes in which the bolts 35 are inserted and they are fastened with nuts (Fig. 5), together with the bottom 31 and the upper part 33 using a flexible plate 35, in which the holes are pierced by the pointed end of the bolt 35.

 The ring 34 is formed by the junction of the cut ends, but there may also be mounting plates. The plate 36 and the strip of ring 34 are made of plastic, for example fiberglass. The upper 33 and bottom 31 parts are crimped with clamps 38 and 37, respectively, on the pipe 27 and the load 32. Thus, horizontal belts of the container 26 are made.

 A cap 25 is put on the pipe 27 and attached to it. The tank 26 is folded on the deck of the vessel and occupies a position as shown in Fig. 8. A winch 3 and a pump 18 are mounted on the platform 1, a pipe 27 is inserted into the hole 2, which is fixed with pins 30, a cable 12 is attached to the cover 25 and the lines 13 and 14 are passed through it, valves 43 and 44 are closed.

 The entire system is released to the surface of the reservoir. Under the action of the load 32 and the hollow ring 28, the container 26 takes on the form shown in FIG. 1. This is due to the fact that the entire tank with a load of 32 has a negative buoyancy, and without it, a positive buoyancy.

 To load the container 26, the lid 25 is removed, the winch 3 is turned, the pump 18 is turned on the table 21 so that the pipe 19 becomes coaxial with the pipe 27, the pipe 20 is connected to the catch selection bridge, the pump 18 is turned on and the fish moves to the tank 26. Similarly, pumping takes place fish from the tank.

 Then the pipe 19 is disconnected, put on and fastened the cover 25 with a cable 12 and highways 13, 14, the pins 30 are shifted and, turning the handle 17, the container is lowered to a depth that corresponds to the habitat of this type of fish. Then winch 3 stops.

 Valves 44 and 43 are opened, regulator 40 controls the supply of a gaseous medium for aeration of the aqueous medium in the vessel 26, regulates the valve 41, which creates pressure in the chamber and provides the supply of the nutrient mixture to the container 26. There is an additional adjustment of the supply of the nutrient mixture using the throttle 42. Then the platform 1 is closed with a hinged casing 24.

 In this form, the entire system can remain for a long time, corresponding to the supply of air in the cylinder 10 and the nutrient mixture in the chamber 11. For loading or unloading by turning the handle 17, the container 26 is lifted by the cable, fixed with pins 30, the cover 25 is removed, the winch 3 is turned and 3 then the table 21 with the pump 18, respectively connect the nozzles 19 and 20 and produce the necessary movements of the fish.

 Canvas 39 must be standard, for example, form a diameter of ≈10 m, and its length is pre-selected, say 20 m.

This corresponds to ≈1600 m ³ and can accommodate ≈500 tons of live fish. It is possible to increase the capacity by increasing the height of the pipe web 39.

 Under the protective casing 24, a beacon is installed, which makes it easy to find a storage for additional loading or unloading.

 The proposed device allows you to pre-conduct basic installation work, put the tanks on deck and, if necessary, quickly dismantle the storage during fishing. In addition, the proposed storage is simpler in design and number of parts.

 The device shows and describes the operations that are performed manually, however, instead of the handle 17, a drive can be installed, also drives can be provided for turning the table 21, winch 3, moving the pins 30, and turning the protective cover 24, as well as for other technological operations. That is, the proposed device is promising and lends itself to substantial mechanization and automation.

 The fish tank in its shape is chosen optimal in the form of a cylinder, although there may be an option when the top and bottom parts are connected on the ring at once, but such a tank will not be very convenient in shape. The weight of the web can also be used as a load, but the technical solution makes the system uncertain in position when the aquatic environment is agitated.

 It is possible to carry out the upper part without a hollow ring and to obtain the desired shape due to the cargo on the bottom without a hollow ring and fastening on a cable, however, it is advisable to have a cargo and a hollow ring on the fish tank itself, so that the form remains without a cable, it is permissible when stored at the bottom a reservoir without a platform, and in this case the cable can be fixed on the shore.

 A case is possible when the cargo tank for fish due to the hollow ring of the upper part will have positive buoyancy. Such a case is also possible for use during storage in the coastal zone without a platform.

 Both of the latter options are possible with the platform, and changing the mass of the load during initial installation or the addition of another hollow ring to the upper part with its fastening. However, the most universal device is a complete set with a platform, the device and the operation of which are described above. Thus, the invention allows to achieve all the goals with an optimal technical solution.
