Description

The invention relates to means for providing amphibious tracked vehicles with fishing capabilities and new seaworthiness due to the equipment of watercraft.

Known craft for equipment of armored vehicles, containing two permeable airborne pontoons, filled with lightweight aggregate and made with the possibility of mounting on the armored vehicle through the bow and stern attachment points, a wing to create lift from the incoming water flow and drain it under the bow of the armored car installed between the pontoons in front armored vehicles with the possibility of fixing it on the inner sides of the pontoons in various positions in height and angle of attack, and stern inserts, fixed ny on the extensions of the side pontoons. For each side pontoon: the pontoon's nasal tip, pointed in plan, made with a tank and with smooth ship contours, the pontoon's aft tip is L-shaped expanded along the inner side, the bottom is made flat with a smooth transition to the wedge rise towards the bow and stern ends. In the stern of the pontoon, a tunnel is made to accommodate the propeller and stabilizer steering wheel. The transmission of torque to the propeller is carried out from the drive wheels of the armored vehicle through a step-up gearbox (see RU 2371350). Armored vehicles equipped with the indicated watercraft received the conditional name “Alligator”. The inclusion of this object in the prior art is due to the fact that it is related to the claimed design according to the circuit and structural solutions.

The closest analogue to the claimed invention in terms of functionality and tactical and technical data can serve as the BP-72 marine fishing boat of the Pribuzhye type (project 70150), equipped with a trawl for fishing according to the feed pattern in coastal marine areas (see information on the website http: //avangardplant.narod.ru). The main tactical and technical data (TTD) of the BP-72 bot:

- main dimensions: length 14.4 m, width 4.9 m, side height - 2.5 m, draft 1.44 m;

- total displacement - 51 tons;

- speed - 843 knots;

- autonomy (in stocks) - three days;

- carrying capacity of a cargo boom - 0.9 tons;

- the volume of the fish hold is 16 m ³ ;

- transportation of fresh catch in containers (with ice or without ice).

The main disadvantages of the BT-72 offshore fishing boat are:

- low seaworthiness; fishing operations with fishing gear are provided for waves up to 3.5 points;

- laborious operations of unloading the catch in boxes, holds, as well as unloading from the vessel to the shore;

- the need to create conditions on board the vessel to preserve the catch (cooling, freezing, etc.);

- the need to install cargo arrows.

The claimed invention is aimed at solving the problem of giving amphibious tracked vehicles new seaworthiness and fishing capabilities, significantly exceeding the capabilities of small fishing vessels.

The technical result that can be achieved with the implementation of the invention is as follows:

- safety of navigation is ensured in case of any sea disturbance;

- provided unsinkability at full load and filling the car body with water;

- the crew is not susceptible to seasickness due to the lack of pitching;

- provided the possibility of fishing at a higher sea level;

- the possibility of passage of shallows (shallows), access to the shore;

- the possibility of placing two trawl fishing schemes with fishing and cargo (combined) winches;

- there is no need to install cargo arrows;

- eliminated the need to load catch in boxes and holds;

- it is not necessary to create conditions for the conservation of the catch (cooling, freezing, etc.), the ability to save the catch in a living form is provided;

- excludes the time-consuming operation of unloading the catch from the vessel to shore;

- the possibility of dumping watercraft from an amphibious tracked vehicle is provided; the machine can be used for its intended purpose;

- the possibility of transporting boats by road and rail was provided.

To achieve the specified technical result, a fishing craft for the equipment of amphibious tracked vehicles is proposed, containing two permeable airborne pontoons, a wing to create lift from the oncoming flow of water and divert it under the fore end of the machine, installed between the pontoons in front of the machine, and feed inserts mounted on the inside aboard the pontoons. Watertight side pontoons are mounted on an amphibious tracked vehicle via bow and stern mounts. Pontoons have the necessary buoyancy and a buoyancy margin, providing unsinkability at full load and filling the car body with water. To accommodate and keep the catch alive, each pontoon has a hold pool with dimensions along the entire length and width of the pontoon (from side to side and from bow to stern), and in height - from a set of bottom to the cargo waterline.

On the bottom of each pontoon, polyurethane foam slabs with a thickness equal to the height of the frame are laid, while the volume of the pontoon above the water line to the deck is filled with cubes of polyurethane foam to ensure unsinkability when filling the car body with water.

In the area of the feed inserts on the deck of the pontoons is a removable utility module with elevation above the surface of the deck to ensure the flow of water.

To ensure the movement of watercraft, propellers driven by hydraulic motors were used, the energy for which comes from the engine with a pump installed in a hopper located in the utility module.

In the aft end of each pontoon, a slip is placed for drawing the trawl to the deck.

To pour the catch from the hut into the hold pool, there is a hatch located on the deck beyond the upper threshold of the slipway, and for pouring the catch from the hold pool on the outer side of the pontoons, two fore and aft hatches with lids opening by moving along the rails upwards are provided.

Each pontoon has an independent trawl circuit with a combined fishing and cargo winch for hauling a trawl mounted on a deck in the bow.

For each side pontoon: the pontoon’s nasal tip is planed with a tank and with smooth ship contours, the pontoon’s aft extremity is L-shaped along the inner side, the bottom is flat with a smooth transition to the wedge rise towards the bow and stern extremities, cheekbone the outer side is rounded, the deck connection to the outer side is rounded to reduce spray formation, a tunnel is provided in the aft part of the pontoon to accommodate the propeller, nozzle and stabilizer steering wheel.

The bow mount consists of a bracket with a lock fixed on the inside of the pontoon and a shoe mounted on the tracked vehicle, and the stern mount consists of a bracket mounted on the rear wall of the tracked vehicle, and a mating socket made in the end of the L-shaped extension pontoon.

An emergency suspension is provided, which serves to prevent the pontoon from bouncing when the bow mount is destroyed.

In pontoons under the deck in the area of the center of gravity of the Alligator fuel tanks are provided with a volume that provides the necessary cruising range.

Further, the essence of the invention is illustrated by the example of the use of watercraft for equipment. For example, snow and swamp tracked conveyor tractor (GT-TM product 536). The transporter-tractor equipped with the proposed craft, in the text of the description is given the conventional name "Alligator" ("Alligator-fisherman").

The dimensions of the craft are selected from the conditions for ensuring the placement and transportation of the maximum possible catch, while ensuring:

- optimal hydrodynamic capabilities;

- patency by land - the maximum possible angles of entry to the shore, the descent from the shore and the clearance of the craft not less than the clearance of the car;

- unsinkability at full load and during flooding of the machine body with water;

- mobility - the possibility of transporting a complete set of watercraft in the same car with a trailer or on the same four-axle railway platform.

The invention is illustrated by drawings, where:

- figure 1 shows the "Alligator", side view;

- figure 2 - "Alligator", a top view;

- figure 3 is a section aa in figure 2;

- figure 4 is a plan of household equipment in the cabin of the conveyor tractor;

- figure 5 is a plan of a removable office module;

- figure 6 - stern mount;

- Fig.7 - nasal mount;

- in Fig.8 - emergency suspension.

The watercraft includes two water-permeable airborne pontoons 1 and 2, mounted on an amphibious tracked vehicle 3 by means of the bow and stern attachment points, wing 4 to create lift from the oncoming flow of water and drain it under the bow of the tracked vehicle 3 and stern inserts 5. Wing 4 is installed between pontoons 1 and 2 in front of the tracked vehicle.

For each side pontoon: the pontoon's nose is pointed in plan and made with a tank and with smooth ship contours, the pontoon's aft tip is L-shaped expanded along the inner side (pos. 6), the bottom of the pontoon is flat with a smooth transition to the wedge lift 7 and 8 to the side of the fore and aft extremities, respectively, the cheekbone of the outer side of the pontoon is rounded. The connection of the pontoon deck with the outer side is rounded to reduce splashing. To ensure the movement of watercraft, propellers 9 are used, driven by hydraulic motors, the energy of which comes from the engine with a pump.

In pontoons under the deck in the zone of the center of gravity of the car, equipped with a watercraft, fuel tanks with a volume providing the required cruising range are provided.

Two feed inserts 5 are located between the feed extensions of the pontoons (pos. 6) behind the machine body and are fixed on the inner sides of the pontoons 1, 2. The inserts 5 are filled with a lightweight filler. Salon for passengers by car will be used as a living room with four beds (Fig. 4).

In the area of the feed inserts 5 on the deck of the pontoons is a removable service module 13 with two or four berths, which rises above the surface of the deck to provide water flow. In the utility module, a hopper 14 is provided for placing the engine with a pump, from which power is transmitted through the hydraulic system to the hydraulic motor 15, and the generator is also located. The engine is similar to the engine of a car.

On the sides of the pontoons on the transom there is a guard rail with splash-proof curtains and doors for the crew to exit (aft).

Pontoons 1 and 2 are mounted on the tracked vehicle 3 by means of the bow and stern mounts.

The bow mount consists of a bracket 17 with a lock 17a, mounted on the inner side of the pontoon 1, 2, and the shoe 18 mounted on the machine, and the stern mount consists of a bracket 19 mounted on the rear wall of the machine, and a reciprocal socket made in the end parts of the L-shaped extension of the pontoon. To drop the craft from the car, it is necessary to open the lock remotely on the nose bracket 17.

To ensure unsinkability in an emergency (for example, unintentional opening of the nose attachment points), emergency suspensions are installed in the area of the nose attachment, which keep the machine connected to the pontoons afloat. The emergency suspension consists of a hook 20, welded on board the tracked vehicle, and the suspension-chipper 21, fixed by the axis 22 in the shells 23 mounted on the pontoon 1, 2.

Each pontoon 1, 2 has a hold pool 24 for accommodating a fish catch, which has an unpressurized structure, self-filling with water at the entrance to the sea. The hold pool is made with dimensions along almost the entire length and width of the pontoon, and in height - from a set of bottoms to the cargo waterline.

In the lower part of the hold basin from the bottom to the upper edge of the height of the frame (to the height of the frame), polyurethane foam slabs are laid.

The upper volume of the pontoon 1, 2 from the cargo waterline to the deck is filled with cubes of polyurethane foam to ensure the unsinkability of the Alligator when filling the car body with water.

On the outer sides of the pontoons below, two hatches (bow hatch 28 and aft hatch 29) with lids opening by moving upward along the guides are provided for outflow of the catch.

On the deck of the pontoons 1, 2 in the fore end there is a combined fishing cargo winch 30 for hauling the trawl 27.

In the aft end, a slip 31 is provided for drawing the trawl to the deck. The slip has a rectilinear shape (i.e. a flat surface) with an inclination angle of 10-12 °. Behind the upper threshold of the slip there is a hatch 25 for pouring the catch from the pile into the hold pool.

At the end of the trawl, a fish-trawl 27 is pulled onto a pontoon. At the same time, there is no need to install cargo arrows, because the low height of the freeboard of the pontoon (35-40 cm) allows you to draw the trawl with a catch onto the deck of the pontoon with winch 30 along slip 31. When fishing with two trawls, each trawl is pulled onto the deck of its pontoon 1, 2. The trawl draw ends when the tail 32 approaches to the inlet hatch 25, through which the catch is poured into a hold pool filled with water. Being in the hold pool, the catch is kept alive for a long time.

To unload the catch, the Alligator at low speed comes ashore and stops at a predetermined location. The bow and stern hatches are opened (or separately) and the catch is emptied. This eliminates the time-consuming operation of unloading the catch from the vessel to the shore.
