Description

The utility model relates to shipbuilding, namely to the fishing fleet, operated in the coastal zones of the seas.

Small fishing vessels manufactured in Russia and abroad are known, for example, a trawl boat (Project 716 Bu, Zapryba, Tallinn) having a hull, a cabin, an engine room with an engine, a fish hold and a fishing gear (Small fishing vessels, 1977 g.). The main significant disadvantages of the known fishing vessel are: the impossibility of its work in a shallow zone; low autonomy; lack of a net hold, a refrigeration unit and a network selector.

The closest analogue to the claimed vessel as a prototype is a vessel mass-produced by the Akhtarskaya shipyard (Primorsko-Akhtarsk), BMP - 74 - a modernized fishing boat including a hull, a cabin, an engine room with an engine, a fish hold and a fishing gear (Collection proposals, 1988).

The main significant disadvantages of the known fishing vessel are: large draft, which does not allow the vessel to work in a shallow zone; lack of mechanization for sampling nets, traps, cutters, etc .; lack of a net hold; lack of a refrigeration unit for cooling a fish hold.

The main task performed by the claimed utility model is to increase fishing productivity and quality delivered to the fish receiving center.

In the proposed vessel, as a utility model, the task is solved by additionally equipping the vessel with a refrigeration unit mounted in the fish hold and engine room, made in the aft part of the hinged side, in the bow - of a net picker, and in the middle part - of a slewing crane with an angle 180 ° rotation.

In addition, the task in the proposed utility model is solved by using a more reliable and simple air-cooled engine as a power plant; supplying the network selection machine with a device for lifting ship and net anchors (for their ropes).

Neither from the patent technical literature, nor from the practice of operating the fishing fleet, we are aware of the presence of a small fishing vessel that has significant features identical to the proposed technical solution.

The signs inherent in the claimed technical solution, in the aggregate (significant differences) are associated with a causal relationship with the solution of the problem of the utility model.

The claimed technical solution can be implemented with its inherent features repeatedly with the solution of the same problem posed to the utility model, which characterizes the compliance with the criterion of "industrial applicability".

The essence of the utility model is illustrated by the drawing, where:

- figure 1 - shows a side view of the vessel;

- figure 2 - shows a top view of the vessel.

The vessel consists of hull 1, wheelhouse 2, aft fishing deck 3, a bow fishing deck 4, a hinged aft bulwark 5, a mast with lights 7, a slewing crane 8, a net hold 9, a cooled cargo hold 10, in which a refrigeration unit 16 is installed , engine room 11, cockpit for fishermen and crew 12, galley 13, a device for retrieving nets and anchors 14, cargo winch 15. In the hull there is a place for transportation and storage of anchors 17 and ropes. It is equipped with a liferaft 18 and lifebuoys 6.

Four cabinets are mounted in the wheelhouse for drying clothes of fishermen (not shown in the figure), air conditioning, etc.

The vessel is operated as follows. Arriving in the fishing area and arranging the fishing gear, fish are caught, the nets or traps are sorted out, the fish is pulled out, sorted by boxes and placed in the fish hold 10, which is pre-cooled by the refrigeration unit 16 to a temperature of -15 ° С. Fish is taken to a shore receiving point or to a receiving vessel.

The selection of networks from the water is carried out from the bow of the vessel using the network sampling machine 14, which has a device for selecting net anchors.

Using a rotary crane-beam 8 and its winch 15 from the side of the vessel, they check the filling of traps and cutters with fish, as well as pouring the catch from any side, followed by sorting, and placing them in boxes and in a fish hold 10.

Then the nets (or traps, or net) are laid out on the aft deck 3, the aft board (ramp) 5 is lowered to the level of deck 3 and the fishing gear and its equipment are noticeable from the aft platform 3. The vessel is controlled from the wheelhouse 2.

After selecting fishing gear, pouring, sorting the catch into crates, storing it in the hold (cooled by installation 16), setting nets or traps, vessel 1 proceeds to the receiving point, workshop, vessel, etc. to unload the catch using a crane beam 8 .

The advantages of the proposed as a utility model of the vessel over the prototype is as follows:

- small draft (up to 0.9 m instead of 1.5 m), allowing fishing at shallow depths and mooring to gentle shores;

- reduction of the vessel’s excessive carrying capacity and its size;

- increase the autonomy of all nodes of the vessel and its stocks;

- equipping the vessel with a lifting mechanism (crane-beam), which provides various lifting operations (loading and unloading) for working with fishing gear;

- supply with a mechanism (network-selection winch), allowing you to choose a network with fish and their anchors for the ropes;

- equipping the vessel with a refrigeration unit that provides cooling of the fish hold and fish (which improves quality and extends the shelf life);

- amenities for the work of the team and fishermen (drying cabinets, air conditioning).
