Description

The system of proactive sounding of the space in front of a moving surface or underwater vessel is intended for use in marine practice to ensure the safety of navigation of marine vessels in difficult meteorological conditions and in poorly known areas of the oceans and seas.

Given the large inertia of large displacement vessels, the probability of encountering an unpredictable underwater obstacle is very high when moving, especially in areas with complex underwater terrain. The sonar systems that all heavy class vessels are equipped with can clearly see in the near zone, but they do not allow reliable information about approaching underwater obstacles: such as shallows, drifting large-sized objects, including mines and icebergs, as well as vessels traveling at intersecting courses, encounters that could be avoided if you had proactive information about an obstacle in the zone of final braking (the distance depends on the speed and weight of the vessel). It is known that the sonars that all large vessels have at their disposal “see” obstacles and drifting objects - high-frequency ones at a distance of up to 20-30 meters, and low-frequency ones - up to 3000 meters, but with a lower resolution and are not suitable for detecting small-sized obstacles and interference .

The purpose of the invention is to provide additional protection for heavy class ships from underwater obstacles. To achieve this, you can use gliders moving in front of the main vessel. Gliders are known - autonomous devices moving under water and periodically floating to the surface, equipped with sensor equipment (sonar, magnetometer). Gliders are widely used for bioresource research, hydrographic measurements, etc. They could be used to obtain operational information about obstacles in the front zone of the vessel, but virtual communication with them through radio and satellite channels is psychologically unacceptable for the captain or pilot.

The use of a glider in free movement in front of a ship carries a number of problems: in such a way there is uncertainty among the captain or pilot that the glider is strictly kept in a given trajectory of the ship. Gliders do not have enough energy to ensure the operation of all equipment, for a long time to work in standalone mode, since the equipment and propulsion devices located on the glider require high energy costs for their operation, which is almost impossible to provide.

Only a rigid binding of the remote instrumentation equipment, located both on the flying and on the floating devices, simultaneously and synchronously moving with the vessel, can provide reliable information necessary for controlling a multi-ton colossus.

According to the Moscow Aviation Institute (Moscow, November 18 - RIA Novosti) a light drone called the Pterodactyl is proposed to scan the battlefield for tens of kilometers around the combat vehicle on the Armata platform. The reconnaissance drone will be connected to the machine with a flexible cable and designed to scan the battlefield for tens of kilometers around. He will be able to circle in a radius of 50-100 meters around the combat vehicle and rise to a height of several tens of meters. Thanks to the flexible cable with which it is connected to the combat vehicle, it will be able to receive electricity and thereby be able to stay in the air for an unlimited time. Compared to drones controlled via the radio channel, Pterodactyl will be able to take on board more equipment since it does not have to carry batteries. Another advantage of a tethered control system, according to the newspaper, is complete protection against information interception.

The essence of the invention lies in the fact that the proactive sounding system of the space in front of a moving surface or underwater vessel consists of two devices: floating and flying, and the floating device consists of a body on which water-jet propulsion devices are located, combined with steering wheels, as well as sonar, magnetometer , depth gauge, swivel searchlight, video camera, GPS sensor with external antenna, self-contained microcomputer, buzzer, flashing light, parking lights, SOS signaling device, gas Tel longitudinal and transverse vibrations. The retention of the apparatus at a given depth of movement is ensured automatically by means of controlled water-jet propulsors. On the body of the flying apparatus are located: a gas control propulsion, combined with the steering wheels, a magnetometer, a video camera, an autonomous microcomputer with an operator program, an acoustic signaling device, a flashing light, marker lights, an SOS signaling device.

The cable-cable connects the devices with the supporting devices on which are located: a dynamometer, a cable tension value sensor, an angular sensor of vertical and horizontal position of the cable-cable.

The power of both devices is produced via cables combined with cables.

Devices: air and floating, move in constant tension mode of cable cables.

The floating apparatus provides a block for the reception and transmission of sonar signals of the sonar navigation system (HANS).

Considering the considerations expressed above, it is proposed to equip large-tonnage surface and underwater vessels with a complex consisting of two vehicles: floating and flying, equipped with the necessary sensor equipment.

The floating apparatus in the initial position is fixed in the lower underwater part of the vessel or on the deck. At the same time, it is constantly connected to the ship with a cable-cable and fiber-optic cable.

The flying apparatus in its initial position is located on a support located in the upper bow of the vessel, and is also connected to the vessel with a cable-cable and fiber-optic cable.

If necessary, the floating apparatus is lowered into the water in front of the vessel and transferred to the operating mode with energy supply via a cable. Then the propulsors are turned on and the floating apparatus in the “tightness” mode of the cable cable and fiber optic cable starts synchronous movement in front of the vessel at a distance that grows with increasing speed of the vessel and thereby provides forward-looking information about obstacles ahead of the vessel at any speed. In the idle position, when the vessel is at a stop or stops, the cable-cable is reeled up, the underwater vehicle is pulled to the vessel and returned to the supports.

The floating apparatus consists of the following main parts and assemblies:

1. Case

2. Water jet propulsion

3. Shock absorber

4. Sonar

5. Magnetometer

6. Depth gauge

7. Camcorder

The floating apparatus in the initial position is mounted on the bearings of the suspension 15 in the lower bow of the vessel. At the same time, with the help of a cable cable 16 and a fiber optic cable 17, the device is connected to the suspension support 15 and the operator panel located in the control cabin of the vessel. To put it into working condition, the operator gives a command to connect the power supply to the device and remove it from the suspension supports 15. The water-jet propulsion 2 is turned on, and the device starts moving in front of the vessel, pulling and unwinding the cable-cable 16. When moving, the device takes up a position in front of the vessel distance that provides proactive information about obstacles ahead of the ship. The included devices: sonar 4, magnetometer 5, depth gauge 6, constantly transmit information via fiber-optic cable 17 to the operator console 20, and the rotary spotlight 9 and video camera 7 constantly scan the space in front of the device, giving additional visual information to the operator console.

Automatic holding of the floating apparatus at a given depth of movement is provided by the operator program 22.

The dynamometer 18, connected to the cable-cable 16, allows you to set and control the necessary level of tightness of the cables for the stable movement of vehicles in front of the vessel.

For additional monitoring and improving the reliability of the hazard warning system, a unit for receiving and transmitting hydroacoustic signals from the hydroacoustic navigation system (HANS) 25 is provided, and the use of a fiber optic cable for receiving and transmitting information from devices located on the device allows to increase the noise immunity of information coming from devices .

In FIG. 2 shows a flying apparatus, consisting of the following parts: housing 1, on which are located: gas control propulsion 2, altimeter 3, magnetometer 4, video camera 5, GPS sensor 6, 7, flashing beacon 8, side lights 9, spotlight 7, cable cable 10, suspension bracket 11, fiber optic cable 12, dynamometer 13, cable tension gauge 14, angle sensors for horizontal and vertical position of cable 16, operator panel 15, autonomous microcomputer 18 with operator program 17.

The flying apparatus in the initial position is on the suspension bracket 11 in the upper bow of the vessel. Using a cable cable 10 and a fiber optic cable 12, the device is connected to the vessel and the operator panel 15, located in the control room, and is ready for use.

The flying device operates as follows: at the signal of the operator, power is connected to the device and it is put into operation, all devices of the device are tested, then the gas control propulsion device 2 is checked and turned on. After that, the device is removed from the suspension support 11, rises and starts moving forward of the vessel, unwinding the cable-cable 10 and the associated fiber-optic cable 12. The device in the process of moving occupies a position ahead of the vessel at a distance providing anticipatory information about obstacles ahead of the ship. The device program operator 17 is displayed on the necessary lead and is transferred to automatic mode. The operator program 17 sets the level of movement of the device in height and distance in front of the vessel, taking into account the predicted situation. The included magnetometer 4 constantly provides information to the operator’s console about massive metal objects located in depth, and the video camera 5 scans the space in front of the apparatus, giving additional visual information to the operator’s console about objects located on the surface of the water. If necessary, the searchlight 7 is turned on to illuminate the scanned space.

When the apparatus moves, the angular position of the apparatus cable relative to the longitudinal axis of the vessel horizontally and vertically is continuously removed from the angular sensor of the support unit 16 and, if necessary, corrections are made for the angular lead and the height of the apparatus. Information from the altimeter 3, magnetometer 4, video camera 5, GPS sensor 6, continuously fed to the autonomous microprocessor 18 of the device, is also displayed on the screens of the navigator and captain.

As a flying apparatus for completing a system of proactive sounding of space, drones of both aircraft and helicopter types can be used.

The use of the system of proactive sounding of space in front of a moving surface or underwater vessel will increase the safety of their navigation on the seas and oceans.

The use of fiber-optic cable for the removal and transmission of information from devices located on a flying device, allows to increase the noise immunity of information coming from devices, and secrecy.

So no one doubts the safety of air traffic. The global air traffic control system of the planet, although it is divided into government segments that are well linked. And, thanks to the fact that comprehensive global satellite systems made it possible to streamline the intense movement of aircraft so much that their accidental encounter between themselves in the air is practically excluded. The thin atmosphere in which flights take place does not hold objects for any longer heavier than air and therefore the air is clean of random objects.

You can’t say about the seas and oceans, where everything that is heavier than air dumps. The oceanic "broth" in which gigantic vessels make movements is fraught with the dangers of an accidental encounter with anything. Despite the perfect equipment of these giants, their huge mass and inertia during movement does not allow, even when they are discovered, to do anything.

Means of early detection of dangerous obstacles are constantly being improved: how shallows, drifting large-sized objects ("wandering" vessels), including mines and icebergs, as well as small vessels sailing with intersecting courses. Meetings that could have been avoided with proactive information about the obstacle in the zone of the final braking of the vessel - alas, no. So, the achievement of the level of safety at sea that has already been obtained in aviation is still a long way off.

The proposed system of proactive sounding of space in front of a moving surface or submarine vessel does not require significant costs for its design, since well-developed components that are widely used in practice will be used. The creation of specialized production and the use of sophisticated equipment is not required.
