RU2137657C1 - Smaller high-speed cargo vessel - Google Patents

Abstract

FIELD: shipbuilding; cargo vessels. SUBSTANCE: vessel has wedge-shaped carrying hull, engines arranged in aft engine compartment closed with hatch closure at the top, wheelhouse combined with galley and WC, guard of cargo deck and ramp in fore portion of vessel. Wedge-shaped form of hull and construction of wheelhouse ensure reduction of mass and possibility of gliding with cargo on board. Construction of hull is simplified due to use of mainly flat structural members. EFFECT: facilitated cargo handling procedure due to reduced height of ramp axis owing to wedge-shaped form of hull. 5 cl, 2 dwg

Description

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

 A single-deck vessel with a bow ramp, cargo deck, superstructure and engine compartment in the aft of the vessel is known. The wheelhouse is located on the superstructure. (Yu. V. Gorbunov et al. "Ships for small rivers", M., "Transport", 1990, pp. 127-129).

 Also known is a single-deck vessel for transporting various cargoes, closest to the proposed solution, comprising a hull, a power (propulsion) installation, a superstructure, an engine room, a cargo deck, a waterproof guard, a ramp in the bow of the vessel (ed. Certificate of the USSR N 1505835, publ. BI N 33 from 09/07/89).

 However, the known vessels do not possess sufficient maneuverability and operational qualities to ensure the mobile transportation of small cargoes in small batches at the same time along reservoirs, main and small rivers.

 The technical result when using the proposal is to create a simple, by design, high-speed cargo vessel with the characteristics and shape of the hull, providing access to the planing mode with cargo on board, as well as facilitating loading and unloading.

 The problem is solved due to the fact that the vessel containing the hull with the cargo deck and the engine compartment, the wheelhouse, the deck guard and the ramp in the bow of the hull, in accordance with the proposed solution, has a shape made in the form of a wedge-shaped in the longitudinal vertical section of the pontoon, tapering into side of the bow and with the minimum possible height of the stern, determined by the size of the engines located 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.

 The execution of the hull in the form of a pontoon in a wedge-shaped shape provides a simplification of the design, a reduction in overall dimensions, and a simplification of the loading and unloading process.

 The facilitation of the bow in relation to the stern favorably affects the provision of the gliding angle during operation with the load and entering the planing 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 loading and unloading of transported goods.

 To access the engines in conditions unfavorable for their maintenance in the engine compartment, a free volume is formed in front of the engines, connecting to the stern 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 aft part behind the steering and sailor seats, installed in its front part on the floor forming the forecastle in which the electrical equipment is located, moreover, the toilet is fenced off by impermeable bulkheads and is equipped with a separate door facing the deck.

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

 In the process of patent research, a device was discovered according to the patent of the Russian Federation N 2033368 C. B 63 B 35/42 of 04/20/95, in which there is a body in the form of a pontoon tapering to the bow, but the device does not solve the above problem of simplifying the process of loading and unloading and ensuring the effect of gliding, the solution of which became possible in combination with other features of the invention, i.e. the present invention meets the conditions of patentability.

 The invention is illustrated by drawings.

 In FIG. 1 shows a ship, side view.

 In FIG. 2 - cargo ship, top view.

 A cargo ship consists of a bearing hull 1, made in the form of a pontoon, having a wedge-shaped shape tapering to the bow, a wheelhouse 2, a guard 3 and a ramp 4.

 In the hull having a cargo deck 5, an engine compartment 8 with engines 9 is placed in its aft part between the transom b and the transverse bulkhead 7.

 In the front of the wheelhouse 2, on the forecastle 10, seats 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. Logging is through the door 16.

 In the forecastle 17 placed electrical equipment and skipper equipment.

 The engine compartment 8 is closed from above by a hatch 18. In front of the engines 9 there is a free volume connected to the aft of the cabin through the hatch 19.

 The ramp 4 has the ability to rotate through the mechanism 20.

 The wheelhouse 2 is connected to deck 5 through resilient elements (not shown).

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

 Loading (unloading) of the vessel is carried out through the lowered ramp 4. Moreover, due to the wedge-shaped hull, the cargo deck 5 and the ramp 4 form a flat surface, which facilitates the loading (unloading) of vehicles on their own.

 Repair and maintenance of engines is carried out through the hatch 18, and in adverse weather conditions through the hatch 19 installed in the aft part of the cabin 2.3
