Abstract

The invention relates to shipbuilding, and in particular to the creation of a shallow-draft towing vessel with high tractive effort on mooring and increased maneuverability, intended for towing various structures and cargoes.

The present invention is directed to the creation of a shallow-draft towing vessel with high pulling forces at mooring and increased maneuverability, due to the twin-screw scheme with the location of the screws with nozzles in the tunnels formed in the bottom of the vessel.

The technical problem is achieved in that the towing boat containing the hull, deck, engine compartment, in which the engines are located between the transom and the transverse bulkhead of the hull, the wheelhouse mounted on the deck, the deck guard and the ramp in the bow of the hull, according to the invention, the chassis the cabin is located towards the bow of the hull, the engine compartment is made with two transverse bulkheads, between which an engine is connected, connected by means of a gearbox to the propulsion system, consisting of two shafts on which the couplings are installed, the shafts pass through the bottom of the vessel and exit into tunnels having the shape of a truncated ellipse formed in the bottom of the ship’s hull, the shafts are equipped with screws that can be rotated in different directions, closed by nozzles and equipped with rudders, not extending beyond the hull of the vessel, a towing device is installed on the aft deck of the vessel’s hull, which enables towing of pontoons, barges, rafts and other structures.

The technical result achieved by solving the problem is expressed in the creation of a small-draft towing boat with great traction on mooring lines and increased maneuverability due to the possibility of rotation of the screws in different directions. Screws are closed by nozzles to increase traction and protection. Installing screws in tunnels formed at the bottom of the vessel significantly reduces draft of the hull and protects the screws from touching the bottom of the reservoir at shallow depths. The location of the towing device on the deck in the aft part of the hull of the vessel provides the possibility of towing due to the rigid or flexible hitch. The wheelhouse is placed towards the bow of the hull for ease of installation in the engine compartment, made with two transverse bulkheads, of an engine with a propulsion system.

Description

The invention relates to shipbuilding, and in particular to the creation of a shallow-draft towing vessel with high tractive effort on mooring and increased maneuverability, intended for towing various structures and cargoes.

It is known a vessel containing a hull, a power plant with a propulsion system, a superstructure, a wheelhouse, an engine room, a cargo deck, a waterproof deck guard, a ramp in the bow of a ship’s hull [1].

A well-known vessel does not have sufficient maneuvering and operational qualities to ensure the mobile transportation of goods through reservoirs and small rivers.

The closest in technical essence and the achieved results, is a high-speed cargo vessel containing a hull, deck, engine compartment; wheelhouse, deck guard and ramp in the bow of the hull. . The vessel is equipped with a device for feeding and removing ballast from sealed containers, which are located in a hull made in the form of a pontoon of a wedge-shaped shape in a longitudinal vertical section, tapering towards the bow and with the minimum possible height of the stern, determined by the size of the engines located in the engine compartment between transom and transverse bulkhead hull. Moreover, the wheelhouse is installed on the deck in close proximity to the engine compartment [2].

A disadvantage of the known is the lack of maneuverability of the vessel, the safety of the screws is not ensured.

The present invention is directed to the creation of a shallow-sitting towing vessel with great pulling forces at mooring and increased maneuverability; due to the twin-screw circuit with the location of the screws with nozzles in the tunnels formed in the bottom of the vessel.

The technical problem is achieved in that the towing boat containing the hull, deck, engine compartment, in which the engines are located between the transom and the transverse bulkhead of the hull, the wheelhouse mounted on the deck, the deck guard and the ramp in the bow of the hull, according to the invention, the chassis the cabin is located towards the bow of the hull, the engine compartment is made with two transverse bulkheads, between which an engine is connected, connected by means of a gearbox to the propulsion system, consisting of two shafts on which the couplings are installed, the shafts pass through the bottom of the vessel and exit into tunnels having the shape of a truncated ellipse formed in the bottom of the ship’s hull, the shafts are equipped with screws that can be rotated in different directions, closed by nozzles and equipped with rudders, not extending beyond the hull, a towing device is installed on the aft deck of the hull,

providing the ability to tow pontoons, barges, rafts and other structures.

The technical result achieved by solving the problem is expressed in the creation of a small-draft towing boat with great traction on mooring lines and increased maneuverability due to the possibility of rotation of the screws in different directions. Screws are closed by nozzles for increase in an arch and protection. Installing screws in tunnels formed at the bottom of the vessel significantly reduces draft of the hull and protects the screws from touching the bottom of the reservoir at shallow depths. The location of the towing device on the deck in the aft part of the hull of the vessel provides the possibility of towing due to the rigid or flexible hitch. The wheelhouse is placed towards the bow of the hull for ease of installation in the engine compartment, made with two transverse bulkheads, of an engine with a propulsion system. The invention is illustrated by drawings and a drawing, where:

Figure 1 - shows a General view of a towing boat, in section;

Figure 2 - shows a towing boat, a top view, in section;

Figure 3 - shows a towing boat, a General view from above;

Figure 4 - shows a towing boat, common from below;

In fig. 1 - shows the bottom of the hull of a towing boat with formed tunnels in the bottom in the form of truncated ellipses.

The towing boat of FIGS. 1-4 consists of a hull 1 with a deck 2 and an engine compartment 3, with an engine 4 being placed between the transverse bulkheads 5.6 of the ship’s hull, wheelhouse 7, located towards the bow of the ship’s hull 1, deck guard 8 and ramp 19 in the bow of the hull 1. The engine 4 is connected via a gearbox 9 to the propulsion system 10, consisting of two shafts 11 on which the couplings are installed 13. The shafts 11 pass through the bottom 14 of the vessel and exit into the tunnels 15 of Fig. 1, having the shape of a truncated ellipse and formed in the bottom 14 of the building 1 court and, on the shafts 11 are set screws 12, rotatably via a reversing gear unit 9 in different directions, the closed nozzles 16 and provided with hydroplanes 17, without departing from the vessel body 1. A towing device 18 is installed on the aft part of deck 2 of hull 1 of the vessel, which enables the towing of pontoons, barges, rafts and other structures.

The operation of the towing vessel consists in connecting it by means of the towing device 18 to the towed structure and moving the towed structure in the desired direction due to the traction developed by the propellers 12 of the vessel. The two-screw scheme makes it possible to provide increased maneuverability due to the possibility of rotation of the screws 12 in different directions and to significantly increase the traction force on the screws 12 without increasing the diameter of the screws 12 and, accordingly, the draft of the hull 1 of the vessel.
