Description

The invention relates to the field of trawling of marine water areas and can be used to disable anti-landing mines and underwater reconnaissance robots having non-contact sonar and magnetic sensors of target and orientation in the coastal zone [1, 2].

Known explosive method of clearance of the coastal zone using elongated explosive charges. [3, 4]

The disadvantage of this method is the low efficiency of minesweeping of anti-airborne mines having magnetic proximity sensors of orientation and target designation in their design. Mine clearance is very cumbersome and requires a large consumption of explosives. In addition, this causes great environmental damage to the coastal zone, which is unacceptable for humanitarian demining. In the event of explosions, it is also possible to disable submarine communications (pipelines, cable lines and energy).

Closest to the claimed invention is a non-contact combined method of trawling sea mines [5]. The combined trawl incorporates devices simulating several physical fields of a ship at the same time in order to trigger the operation of multi-channel (combined) non-contact mine detonators. The combined trawl creates hydroacoustic, hydrodynamic [7] and magnetic fields recorded by the corresponding mine sensors. Similar sensors have also modern underwater reconnaissance robots. The emulated simulation fields have low intensity, comparable in magnitude with the fields created by targets (ships).

The disadvantages of this method is the low reliability of trawling modern contactless mines that can distinguish false simulating physical fields from real fields created by ships. In addition, this does not ensure the failure of underwater intelligence robots that do not have their own explosive charge.

The technical result of the invention is to increase the reliability of the clearance of anti-landing mines with non-contact sonar and magnetic sensors of the target and underwater intelligence robots.

It is proposed to use simultaneous impact on their sensitive seismic-acoustic and magnetic sensors for the clearance of anti-landing mines with non-contact detonators and reconnaissance robots. Simultaneous exposure provides a more severe violation in the functioning of the electronic circuit of the integrated signal processing of underwater objects.

Non-contact anti-airborne mine fuses and sensors of underwater reconnaissance robots have a certain dynamic range of operability in terms of the amplitude of the acting physical fields [6, 8].

Sensitive sensors of mechanical pressure (hydroacoustic) lose their operability upon impact with an amplitude of more than several hundred atmospheres, and magnetic fields with an amplitude of more than several hundred A / m [8-10].

Thus, a pulsed impact with a large amplitude disables the sensors of the target and orientation of the anti-landing mines and underwater reconnaissance robots, which leads to their neutralization. Since a pulsed magnetic field penetrates through the thin-walled metal shell of an underwater object, this also leads to disruption of the functioning of electronic circuits [10]. This increases the reliability of the disposal of these objects.

Hydroacoustic shock impact is due to the effect of electrohydraulic shock, which can create a pulsed pressure of several hundred atmospheres or more, near a high-voltage underwater spark gap [11, 12].

Shock magnetic action is carried out from a conductive non-grounded circuit. The circuit can be made in the form of a frame or a solenoid. A high-voltage underwater arrester and an ungrounded conductive circuit are connected to the output of a pulsed high-voltage source of electrical energy.

The drawing shows a structural diagram of a device that implements the proposed method of clearance of anti-landing mines with non-contact detonators and underwater intelligence robots.

The neutralization device contains a high voltage pulsed power source 1, an open conductive circuit 2, a high voltage underwater spark gap 3.

The neutralization device operates as follows.

High-voltage pulses from source 1 are fed to a pulsed magnetic field source in the form of an ungrounded conductive circuit 2 and an electro-hydraulic shock source in the form of a high-voltage underwater spark gap 3. These sources form a pulsed magnetic and mechanical electro-hydraulic shock impact on sensitive sensors of the magnetic field 4 and hydroacoustic field 5, incapacitating them. In addition, the pulsed magnetic field from the source 2, penetrating through a thin-walled metal shell (body) of the target (mine, robot) 6, disrupts the operation of the electronic circuits of this object.
