Description

The invention belongs to the field of shipbuilding and can be used as a universal base for any sea and river vessels.

A combined vessel is known, containing one or more hulls with wings that extend to create aerodynamic lifting force when the vessel is moving, which contains one or more free-piston gas generators, a system of gas pipelines connected to the gas generator for gas injection, one or more water-jet thrusters in the form of an air cushion, a system of stabilizing the vessel relative to the water surface, wedge-shaped walls along the bottom of the vessel and air cushions, sealing spring-loaded plates with limiters of their movement in front and behind the air cushions, while the rear plate forms an adjustable nozzle of the water-jet thruster; in addition, it contains one or more additional engines in the form of a pair of air or propellers on the shafts of a two-stage turbine connected to the gas pipeline, while the propellers are of opposite rotation (VO 2002102058 AT, VbOM 1/00, 20031.

A known ship that contains two hulls with a stern in the form of a transom, connected at the stern by means of a controlled temporary attachment. Each hull has a vertical well with a cylinder movably inserted into it, and the cylinder houses the internal combustion engine(s), a two-stage gearbox and a propeller fin. Water jets, or semi-submerged propellers, or Arneson drives, or corner columns, or air propellers are used as engines for full-stroke power plants (ВО Мо 2572180 СИ, Вб6ЗВ 3/08, ВбЗВ 1/0, В6ЗВ 35/00 1/10 2015) .

The closest to the claimed invention is the main power plant of a high-speed vessel with air caverns on the bottom, containing two marine gas turbine power plants, each consisting of a gas turbine engine, a propeller shaft with a propellant in the form of a water jet or an adjustable pitch propeller, a fan and a gear gearbox, which includes an input shaft connected to the power shaft of the gas turbine engine with an overrunning clutch on it, toothed gears and wheels, an intermediate shaft connected to the propeller shaft, the main output shaft with an installed on it with the possibility of communication using friction clutch hydraulically controlled by an output cylindrical wheel inside it, on the side surface of which a bevel wheel is fixed, which is in engagement with the bevel wheel placed on the main output shaft perpendicular to the side output shaft, and where the gear reducers of the power plants are turned to each other by the side output shafts , between the output ends of which is placed n a spur shaft with the possibility of connecting gear reducers to each other using this shaft and a friction clutch with hydraulic control, made at the output end of the side output shaft of one of the gear reducers. The intermediate shaft in each of the gear reducers, which is engaged by the gear wheel with the gear shaft of the input shaft, is made with the output end, to which the shaft of the fan for blowing air into the air caverns on the bottom is connected (VOYU Me 147169 01, Vb6ZV 1/38, 2014 ).

The specified prototype, like the previous analogues, has one type of propulsion - a gas turbine, which significantly reduces its overall reliability and economy at low turbine speeds.

The invention is based on the task of creating a universal, multifunctional propulsion system for sea and river vessels, which would be reliable and economical, allowing it to be used during the movement of vessels in a wide range of speeds without the installation of additional equipment.

The problem is solved by the fact that the propulsion system for sea and river vessels, which contains two gas turbine power plants, each of which includes a gas turbine, which is connected to a water jet engine through a gearbox, according to the invention, contains a third gas turbine power plant and two electric power plants, each of which contains a generator for recharging the batteries feeding the electric motor and the electric motor itself with a drive on a retractable rotary propeller, while the electric motors with drives are located between the gas turbines in vertical shafts made inside the ship's hull.

The electric motor and the propeller make up one unit, located in a vertical shaft with the possibility of lowering to ensure the movement of the vessel and raising back into the shaft when the movement stops.

The propeller has an annular nozzle, a closing rectangular plate is attached to the annular nozzle from below, made with the possibility of closing the vertical shaft flush with the bottom of the vessel when the electric motor assembly with the propeller is raised, and the annular nozzle in plan has a rectangular shape for free movement inside the vertical shaft because the rectangular section and is made as one unit with a closing rectangular plate.

The engine-propulsion system for sea and river vessels, which is claimed, ensures the movement of the vessel in a wide range of speeds, up to 60 and above knots on gas turbines, with a multiple increase in the range of the vessel with regular fuel reserves at speeds of 7-12 knots on electric motors.

The multifunctionality of the engine-propulsion installation consists in the possibility of building ships of various purposes: passenger, cargo, special, etc., which use, at different moments of time, the merits and advantages of one or another engine-propulsion complex for the optimal performance of the tasks assigned to the ships.

The combination of gas turbine power plants with water-jet engines and electric power plants with drives on retractable rotary screws allows the system to be used in various driving modes without installing additional equipment.

Electric power plants are used at speeds of 7-12 knots, allowing the ship to cover 5-10 times more distance with the same amount of fuel than when using gas turbine plants.

A high degree of reliability is provided by the presence of two electric power plants with rotary propellers that are removed into the hull, and three gas turbine power plants, instead of two, as in the prototype.

The system has five power units independent of each other, each of which can independently ensure the ship's progress.

A high degree of economy is provided by the use of low-power electric motors with a coefficient of useful action and a torque significantly higher in comparison with internal combustion engines, and the presence of three gas turbine power plants that can work both together and separately.

The presence of rotary propellers of electric power plants provides increased maneuverability of the vessel, the ability to make U-turns in almost one place.

The invention is explained with drawings.

In Fig. 1 schematically depicts a high-speed sea (river) vessel; in Fig. 2 schematically shows the propulsion system for high-speed sea (river) vessels;

From in Fig. C - a vertical mine with a propeller and an electric motor; in Fig. 4 - bottom view of the vessel.

The propulsion system includes three gas turbine 1 power plants and two electric 2 power plants (Fig. 2).

The gas turbine 1 power plant consists of a gas turbine 3, which is connected to a water jet engine 5 through a reducer 4.

Water jet engines 5 have inlet 6 and outlet 7 openings (Fig. 4).

The electric 2 power plant contains a generator 8 for recharging the battery 9, which powers the electric motor 10 with a drive on the rotary propeller 11, which is removed.

Electric motors 10 with drives are located between gas turbines C in vertical shafts 12 made inside the ship's hull (Fig. 3).

The electric motor 10 and the rotary propeller 11 make up one node, located in the vertical shaft 12 with the possibility of lowering to ensure the movement of the vessel and raising back into the shaft 12 when the movement stops.

The propeller has an annular nozzle 14, on which a closing rectangular plate 15 is fixed, made so that it can close the vertical shaft 12 level with the bottom 13 of the vessel when the assembly of the electric motor 10 with the propeller 11 is raised, and the annular nozzle 14 in plan has a rectangular shape for free movement inside the vertical shaft 12 of rectangular section.

Electric 2 power plants are used at low speeds, have a relatively small power, which is transmitted to the drive - rotary propellers 11.

A high-speed marine vessel has two options for movement: on electric motors 10 and on water jets 5.

When the vessel moves on electric motors 10, they are lowered from the vertical shaft 12 so that the rotary propeller 11 is located below the plane of the bottom 13 (this position is shown in dashed lines in Fig. C). When moving on water jet engines 5, the rotary propeller 11 is not used and is in a raised position in a vertical shaft 12, closed flush with the bottom by a locking plate 15.

When the assembly electric motor 10 - propeller 11 is raised, the locking plate 15 closes the opening of the vertical shaft 12. Thus, the assembly electric motor 10 - propeller 11 is completely hidden inside the vertical shaft 12, and no elements protrude beyond the surface of the bottom

The inclusion of gas turbine units in operation is carried out in such a way that the ship can run on one, two or three units at the same time. Thus, in a wide range of speeds, fuel economy is achieved both due to the operation of the number of units necessary for a given speed, and in providing the most economical powerful indicators for the turbines - operation at capacities of 50-90 95 from the maximum.
