Abstract

FIELD: shipbuilding.

SUBSTANCE: invention is related to propulsion for river vessels, mainly for shallow rivers. The towing vessel contains a displacement body, an internal combustion engine with an electric generator and a propulsion unit. The engine is made in form of two side-by-side annular garlands, hollow balls, hingedly connected and containing a rotational drive mechanism inside. The axes of the balls are located outside their shell and interact with current-transmitting electric buses.

EFFECT: high efficiency of the propulsion is achieved.

Description

The invention relates to the field of transport engineering, namely the device of river vessels, mainly for shallow rivers.

Known projects of river vessels with propellers directly affecting the bottom of the water area (patents RU No. 2391248, 2382716). The first involves the use of a caterpillar chain with tracks in the form of buckets, which is practically unacceptable, since the bottom of rivers, especially shallow ones, is polluted with various debris (logs - firewood, etc.) and which will inevitably put this mover out of action. The second project involves the use of poles as propellers, but they will not be able to provide the necessary traction and are suitable only for small boats.

The aim of the invention is to create a workable and highly efficient (with high efficiency) propulsion for river vessels.

This goal is achieved by the fact that in a towing vessel containing a displacement body, an internal combustion engine with an electric generator and a propulsion device, according to the invention, the propulsion device is made in the form of two side-by-side annular garlands of hollow balls connected pivotally and containing a rotational drive mechanism inside. In this case, the axes of the balls located outside their shell interact with current-transmitting electric buses. And the rotary drive mechanism is made in the form of an electric motor with a planetary gear. The shell of the balls is made of steel or cast iron with a rubberized treadmill. And their inner cavity is filled with a dielectric liquid.

Figure 1 shows the vessel, side view. Figure 2 shows the internal structure of the balls.

The vessel consists of a displacement hull 1, along the sides of which racetracks 2 for balls 3 are mounted. The latter are assembled into an annular garland with the help of levers with hinges 4. Balls 3 have a steel/cast-iron shell 5 with a rubber-coated treadmill 6. Outside the balls 3, there are axes 6 and 7 isolated from the shell 5, in contact with current-carrying tires 8. Inside the balls 3 and coaxially with them, electric motors 9 with planetary gears 10 are installed. hinges 4 connecting the balls 3 of the dielectric material and interact with the axes 6 and 7 through the freewheel mechanisms (MSH) 11. In the aft part of the hull 1 there is a retractable tensioner 12 (the extension mechanism is not shown). Electric motors 9 are equipped with pendulum weights 13. And the internal cavity of the balls 3 is filled with a dielectric liquid (for example, denatured alcohol) 14.

The vessel operates as follows. With the ship standing in shallow water, already assembled, but still open, garlands of balls 3 are laid side by side on the bottom, the ends of which then simultaneously rise from the bow and stern to the treadmills 2 and close with hinges 4. After that, using the tensioner 12, the garland of balls 3 is given the optimal location (depending on the topography of the bottom and the depth of the reservoir). Next, electrical voltage is applied to the tires 8 and which, through the axes 6 and 7, is supplied to the electric motors 9. The latter, through the gearboxes 10, begin to rotate the balls 3, which, rolling along the treadmills 2, set the vessel in motion. At the same time, the rolling of balls 3 along the bottom of the reservoir is prevented by MCX 12.

This vessel is intended for towing barges (one or several) with a small draft (flat-bottomed option) along shallow (mainly) rivers. Maneuvering of the vessel is carried out according to the "tractor" one, by stopping one of the garlands of balls 3. When installed on balls 3 instead of rubber rings 6 rings with lugs (not shown), this vessel can be operated in winter, already as an icebreaker.
