Description

The proposal relates to shipbuilding, in particular to vessels for the transport of various goods in small portions.

Known single-deck vessel with a nasal ramp, cargo deck, superstructure and engine compartment in the stern of the vessel. The wheelhouse is located on the superstructure. (Yu.V. Gorbunov et al. “Ships for small rivers”, Moscow, “Transport”, 1990, pp. 127-129).

It is also known single-deck vessel for transportation of various goods, closest to the proposed solution, comprising a hull, power (propulsion) installation, superstructure, engine room, cargo deck, waterproof fencing, ramp in the bow of the ship (author. Svid. USSR № 1505835, publ .BI number 33 from 09/07/89).

However, the well-known vessels do not have sufficient maneuverability and performance to ensure the mobile transportation of small loads in small batches simultaneously along reservoirs, main and small rivers.

The technical result when using the proposal is to create a speedy cargo vessel with a simple design with characteristics and hull shape, providing access to the gliding mode with cargo on board, as well as facilitating loading and unloading operations.

The task is solved due to the fact that the vessel containing the hull with the cargo deck and the engine compartment, the wheelhouse, the deck enclosure and the ramp in the forward part of the hull, in accordance with the proposed solution, has a shape made in the form of a pontoon wedge-shaped in a longitudinal vertical section the side of the bow and with the minimum possible height of the stern, determined by the size of the engines placed in the engine compartment between the transom and the transverse bulkhead of the hull. Moreover, the wheelhouse is installed on the deck in close proximity to the engine compartment.

Execution of the hull in the form of a wedge-shaped pontoon provides for simplifying the design, reducing the weight and size characteristics, and simplifying the process of loading and unloading.

The relief of the bow in relation to the stern has a favorable effect on ensuring the gliding angle during operation with a load and entering the gliding mode, which allows you to move at a higher speed.

The reduced height of the bow of the hull determines the lower position of the ramp relative to the unequipped shore, reducing its length and facilitating the loading and unloading of the transported goods.

For access to engines in conditions unfavorable for their maintenance in the engine compartment, ahead of the engines, a free volume is formed, which connects to the aft part of the cabin through the hatch.

To reduce the size and weight of the wheelhouse and at the same time ensure the convenience of the crew, the latter is combined into a single unit with a galley and a toilet, located in its stern behind the steering and sailor’s seats installed in its front part on the floor, forming the forecastle, in which the electrical equipment is located The toilet is fenced with impenetrable bulkheads and provided with a separate door leading onto the deck.

The hull and logging forms are formed mainly by flat surfaces, which reduces the complexity of its construction.

In the course of the conducted patent research, the device according to the patent of the Russian Federation No. 2033368 class was revealed V63V 35/42 of 04/20/95, in which the hull is constructed as a pontoon tapering towards the bow, however, the above-mentioned device does not solve the above problem of simplifying the loading-unloading process and ensuring the gliding effect, which was possible in combination with other features of the invention, i.e. The present invention complies with the conditions of patentability.

The invention is illustrated by drawings.

FIG. 1 shows a ship, side view.

FIG. 2 is a top view of a cargo ship.

The cargo ship consists of a carrying hull 1 made in the form of a pontoon having a wedge-shaped form in DP, wheelhouse 2, fence 3 and ramp 4.

In the case, having a cargo deck 5, is located in its stern between the transom 6 and the transverse bulkhead 7 engine compartment 8 with engines 9.

In the front of cabin 2 on the forecastle 1 0, chairs 11 for the helmsman and sailor are installed, and in the aft part there is a galley 12 and a toilet 13 fenced by bulkheads 14 and equipped with a separate door 15. The entrance to the cabin is through door 1 6.

In the forecastle 1 7 placed electrical equipment and skipper equipment.

The engine compartment 8 is closed on top of the hatch cover 18.

In front of the engines 9 there is a free volume, connecting with the aft part of the cabin through the hatch 19.

Ramp 4 has the ability to rotate through the mechanism 20.

Cabin 2 is connected to deck 5 through elastic elements (not shown).

The deck behind the cabin 2 is covered with an awning 21.

Loading (unloading) of the vessel through a lowered ramp 4. At the same time, thanks to the wedge-shaped hull, cargo deck 5 and ramp 4 form a gentle surface that facilitates loading (unloading) of vehicles with their course.

Repair and maintenance of engines are carried out through the hatch cover 18, and in adverse weather conditions through the hatch 19, installed in the aft cabin 2.
