Description

The invention relates to the field of underwater shipbuilding, namely to the device of submarines.
Known submarine with hydraulic torpedo tubes (RF patent No. 2324620, dub. 05/20/2008), containing a sturdy hull, lightweight hull, high pressure air system, torpedo tube filling and draining system with front and rear drainage valves, valves ventilation and piping. Hydraulic torpedo tubes are installed with their breech inside a sturdy hull, and the front part, which has a kingston, in a pulse tank located between the sturdy and light hulls. At least two hydraulic torpedo tubes are integrated into a module on a bulkhead plate welded into a sturdy submarine hull and having holes for connecting a torpedo tube filling and draining system outside the durable piping body with front and rear torpedo tube drainage valves installed on the inside of the plate, connected by a pipeline with a torpedo-tube filling-draining system. In addition, a battle cylinder connected to a battle valve mounted on the inside of the plate and connected by a pipeline to the turbopump is connected from the outside of the plate with a large neckline. The opposite side of the combat cylinder has pipelines for filling and purging it, connected by a purge valve installed on the inside of the plate and a cylinder filling valve, connected by a pipeline to the ship’s high-pressure air system.
The main disadvantage is the use of high pressure air as a source of energy, for the following reasons:
- the processes of air outflow from a combat balloon during firing and filling of a combat balloon during reloading are characterized by high noise, which is a factor that unmasks the firing submarine;
- when firing a large amount of air is discharged into the compartment of the submarine, which leads to an increase in pressure and a drop in temperature in the compartment and is a danger to personnel and equipment. In this case, the use of effective silencers or receivers is impossible, since this will cause an increase in pressure at the outlet of the turbine and lead to a drop in power. For the same reason, it is impossible to ensure the release of technical equipment from the launch tube at low speed, because long-term operation of the turbine will be required, which will lead to even more air discharged into the compartment;
- the high complexity of regulating the speed of the shot products - requires the development of specialized high-speed pneumatic equipment of large passage area and its adjustment.
A marine vessel, for example, a submarine, is known (application US No. 2005/0051076, publ. 03.10.2005), adopted as a prototype and containing an outer light hull, an inner strong hull and a launcher having at least one launch tube , an impulse liquid tank installed in the outboard space between the light and durable housings. The pulse liquid tank has an inlet for water to enter the pulse tank and an outlet connected to the launch tube, and a vane pump with an electric motor inside the pulse tank for compressing the liquid in the pulse tank to direct pressurized liquid to the launch tube through the output of the pulse tank to start payload from the launch tube.
The main disadvantage is the placement of the pump motor in the outboard space between the light and durable housings, resulting in the following negative consequences:
- the presence of an engine and communications that conduct high currents of a strong hull of a submarine entails the need for special measures to exclude the formation of a magnetic field that unmasks the submarine;
- vibration from the operation of the electric motor in this embodiment is perceived by the structures of the outer hull and the pulse tank, which have significantly lower rigidity than the designs of the main hull, which leads to the transmission of vibrations to these structures and, as a result, an increase in the noise of the submarine;
- inspection, maintenance and repair of the engine or its elements when the submarine is in the underwater position and the engine is below the cruising waterline is impossible without placing the submarine in the dock. When the engine is located above the impulse tank, above the cruising waterline, the engine can be inspected and serviced in the above-water position and on the base without docking, however, the high location of the pump unit reduces the cavitation reserve and limits the use of the launcher at shallow depths of the submarine due to the possibility of formation cavitation;
- the performance of the engine in an outboard version is associated with the need to fill it with a special liquid or to ensure the flow of overboard water. In both cases, the presence of liquid in the gap between the rotor and the stator will create an additional moment of resistance to rotation, and in the presence of outboard water inside the engine, scaling and biological fouling of structures are also possible, which reduces the reliability of the launcher.
The objective of the invention is to develop a submarine with an electro-hydraulic launcher with a layout scheme that allows you to eliminate these disadvantages.
The technical result is to reduce the noise of the submarine and improve the operational characteristics of the submarine, namely, increasing its reliability and maintainability.
The technical result is achieved in that in a submarine with an electro-hydraulic launcher, including an outer hull, a main hull and an electro-hydraulic launcher, including at least one launch tube, an impulse tank installed in the outboard space between the hulls, with a vane pump, an input for water inflow from the overboard space and the outlet associated with the launch tube, and a pump motor, a pump motor installed inside the main body of the submarine and connected to the impulse pump of the impulse tank using a shaft, while the passage of the shaft through the main body is equipped with a sealing device with a turn-off static seal that is able to completely seal the main body, and at least one sealing device with a dynamic shaft seal made with creating a low moment of resistance to rotation of the shaft when disabling the static seal.
The electric motor, pump, shaft and sealing devices can be made in the form of a single unit located in a single housing installed in the welded cup of the main body of the submarine.
At least one launch tube is brought out with its rear cut into the main body of the submarine with the possibility of recharging it from the main body.
At least one launch tube can be installed in the outboard space between the outer and main hulls of the submarine.
The pulse tank can be made in the form of a pipeline connecting at least one starting pipe to the pump.
The launcher can be equipped with a motor control device, configured to select the parameters of the electric motor depending on the type of product being thrown out and the external conditions, and controlled by a converter combined with the electric motor in an adjustable electric drive.
The installation of a pump motor inside the main body of the submarine reduces the noise of the submarine due to the absence of such unmasking signs as the magnetic and acoustic field of the working electric motor in the outboard space, as well as due to the absence of vibrations from the electric motor transmitted directly to the aquatic environment and to the light structures of the submarine .
Installing a pump motor inside the submarine’s main hull increases the reliability of the submarine. Due to the lack of sea water inside the motor in the gap between the rotor and the stator, the possibility of scaling and biological fouling of the structure is excluded, which increases the reliability of the pump motor and the launcher.
In addition, the electric motor, designed to be placed in the main body of the submarine, has a much simpler and more technological design. And also, it is not necessary to ensure the output of large electric cables through the main submarine case, namely the welding of glasses in the main case, the installation of current leads, the use of cables with longitudinal sealing of insulation.
Installing a pump motor inside the main hull of a submarine increases the maintainability of the launcher and submarine. Since the location of the electric motor in the compartment of the main body of the submarine provides quick access for inspection, maintenance and repair of the electric motor without docking the submarine.
The presence of the connecting shaft and sealing devices allows you to install the launcher motor in the main hull of the submarine.
The presence of a sealing device with a turn-off static seal ensures the tightness of the passage of the connecting shaft through the main body in standby mode and in preparation for launching the gun.
The presence of a sealing device with dynamic shaft seal provides a low moment of resistance to rotation of the shaft during operation of the pump motor with short-term incomplete sealing of the main body. During operation of the electric motor, the static seal is disconnected and does not create braking of the rotating shaft.
The invention is illustrated by drawings, where in FIG. 1 shows a layout of an electro-hydraulic launcher, a pulse tank, a pump and an electric motor in a submarine according to an example of embodiment. In FIG. 2 shows diagrams of sealing devices with static and dynamic seals according to an example of execution.
Execution example. A submarine with an electro-hydraulic launcher includes an outer hull 1, a main hull 2, a launcher including at least one launch tube 3, an impulse tank 4 with a pump 8, and a pump motor 9 connected to the pump 8 via a shaft 10. Place of passage shaft 10 through the main body 2 is equipped with one sealing device 11 with a switchable static seal, and at least one sealing device 12 with a dynamic seal of the shaft 10.
The launch tube 3 passes through the main body 2 and the pulse tank 4, the front section of the launch tube 3 is located opposite the shield 15 in the outer case 1. The rear section of the launch tube 3 with the back cover 14 is installed inside the main body 2 to enable recharging of the launch tube 3 from the compartment submarine. The part of the launch tube 3 passing through the pulse tank 4 is equipped with a kingston 7 with a drive, which is the output of the pulse tank 4 and is designed to communicate the pre-filled outboard water 3 of the launch pipe 3 with the pulse tank 4 when preparing the launch pipe 3 for a shot and disconnect the launch pipe 3 s pulse tank 4 when draining the launch pipe 3. To fill or drain the launch pipe 3 is connected by a pipe 21 through the shut-off valve with a tank of overboard water 20.
The impulse tank 4 is a collector around one or several launch tubes 3 and is designed to supply water under excess pressure, relative to the outboard, from the pump 8 to one of the launch tubes 3 and create an ejection pressure on the stern of the product 16 in the launch tube 3. Pulse the tank 4 is installed in the outboard space between the outer and main bodies 1 and 2. The pulse tank 4 is made with an inlet 5 for water intake connected to the outboard space with a water conduit 6, and with an outlet connected to the launch tube 3 and arranged on the wall of the launch tube 3. The output pulse of the tank 4 is made in the form of sea valve 7 and is designed to release water injected into the impulse tank 4, a launch tube 3.
Excessive water pressure in the pulse tank 4 for starting the product 16 is created by a vane pump 8, which is installed at the entrance to the pulse tank 4 and is driven by an electric motor 9. The electric motor 9 is installed inside the main body 2 and is connected to the pump 8 by means of a shaft 10 passing through main building 2.
The electric motor 9, the controlled Converter 18 and the control device 19 are an adjustable electric drive.
The electric motor 9 is designed to convert electrical energy coming from a controlled Converter 18 at a mechanical moment on the output shaft. A controllable converter 18 converts electrical energy from a storage device 17 or the submarine’s onboard power supply into a power supply with the required current and voltage parameters. The control device 19 is designed to control the moment on the output shaft of the electric motor 9 by changing the output parameters of the controlled transducer 18 depending on the type of ejected product 16 and external conditions.
The sealing device 11 with a disconnectable static seal of the main body 2 is configured to completely seal the main body. The sealing device 11 is made in the form of a clamping ring 22 with a radial rubber seal 24 and with an end rubber seal 23, which is pressed against the thrust element on the shaft 10 under the action of the hydraulic actuator 25.
At least one sealing device 12 with a dynamic shaft seal 10 is configured to create a low moment of resistance to rotation of the shaft 10 when the static seal is turned off. The sealing device 12 is made in the form of a radial rubber seal 28 and an end seal 27 made of a material with a low coefficient of friction, for example carbon fiber, and mounted on a metal base, for example, a ring 26, which is pressed against the thrust element on the shaft 10 under the action of the springs 29 and overboard pressure. Full tightness of the passage of the shaft 10 of the motor 9 through the main body 2 is not provided, however, given the speed of the shot process, the total number of leaks is negligible. To collect leaks with incomplete sealing of the main body 2, any of the overboard water tanks available on the submarine, for example, tank 20, can be used to fill launch tubes with water in preparation for launching the launch vehicle. Sealing devices 11 and 12 can be made in a single housing.
The electric motor 9, sealing devices 11 and 12, the pump 8 can be made in the form of a single unit placed in a single housing, which can be installed in a welded cup of the main body 2 of the submarine (not shown). The assembly of such a single unit, housed in a single building, at a specialized engineering company is characterized by higher accuracy and alignment along the shaft line 10, which further reduces the noise and other operational characteristics of the submarine. The presence of a single hull allows you to partially compensate for the deformation of the main hull 2 that occurs when the submarine is submerged, and a decrease in the length along the horizontal axis as compared to the version with individual elements reduces the bending of the shaft 10, which increases the reliability of the launcher and the submarine. Installation of a single unit can be carried out from the main body 2, which increases maintainability.
A submarine with an electro-hydraulic launcher operates as follows. In the initial position, the impulse tank 4 is completely filled with seawater entering through inlet 5 and the conduit 6 from the outboard medium, while the starting pipe kingston 7 is closed. The sealing device 11 is turned on and is in a position ensuring complete tightness of the passage of the shaft 10 through the main body 2 The product 16 is located in the launch tube 3. The front 13 and rear 14 of the launch tube cover are closed. In preparation for firing, the launch tube 3 is filled with water from the overboard water tank 20 through the filling / drainage pipe 21 and the pressure is equalized with the overboard, then the front cover of the launch tube 13, shield 15 and kingston 7 are opened. Immediately before starting the shot, the sealing device 11 is turned off, this overboard water under pressure partially passes through the sealing device 12 into the tank 20 overboard water.
After giving a shot command, through a controlled converter 18, power from the drive 17 or from the on-board network is supplied to the windings of the electric motor 9. The electric motor 9 converts electrical energy into torque on the shaft 10. Pump 8 converts the torque on the shaft 10 into the kinetic energy of the fluid pumped from the overboard space through the conduit 6 to the pulse tank 4, which leads to an increase in pressure in the pulse tank 4. The pressure through the aqueous medium is transmitted to the launch tube 3 through open Kingston 7. Under By the action of force caused by excessive pressure on the back of the product 16, it begins to move towards the front cut of the launch tube 3 and, thus, is ejected from the launch tube 3.
At the end of the shot, the power of the electric motor 9 is turned off, the sealing device with a static seal 11 is turned on. Covers 13 and 14 and Kingston 7 are closed, the launch tube 3 is drained. The pulse tank 4 is filled with water from the conduit 6 through the inlet 5.
Thus, the invention provides a reduction in the noise of the submarine and an increase in its reliability and maintainability.
