Description

 The invention relates to the field of military equipment, mainly armored. and can be used to improve the protection of crew members of a combat vehicle from the shock wave of a nuclear explosion and radioactive substances by sealing the fighting compartment of the tank.

 Operational experience of tanks shows that the effective protection of the tank crew from the shock wave of a nuclear explosion and radioactive substances will be in the case when the wedge of the shutter of the gun is closed. Otherwise, when the shutter wedge is open, the operation of the collective protection system (RMS) will not provide for the sealing of the tank hull.

 For protection against weapons of mass destruction of a tank crew in normative and technical documentation, for example (see Tank T-72M. Technical description and operating instructions. Book 1. Edition N 3/019988 p - P-82. Pages 236 - 264 .) a collective protection system is provided. It will be effective in the case when the bolt wedge is closed, but we cannot guarantee the presence of a bolt-locked bore of the gun barrel at the time of a nuclear explosion.

 Therefore, constructive automation of the process of closing the wedge of the shutter of a tank gun when the collective defense system is triggered is an important military-technical task.

 For the prototype for creating a device for automatically closing the wedge of the tank gun’s shutter when the collective defense system is triggered, the well-known system of protection against weapons of mass destruction of the T-72M tank is taken (see T-72M tank. Technical description and operating instructions. Book 1. Edition No. 3 / 019988 p - P-82. Pages 236 - 264.) consisting of a battery switch, an automation unit, a control panel for a driver, a relay box, a gamma sensor, an electromagnet for blinds, a control and alarm panel, temperature sensors, and buttons th redundancy, electrical installation, the rotary contact arrangement.

 The problem solved by the invention is the provision of reliable sealing of the fighting compartment and the control compartment of the T-72 tank when the SKZ is triggered.

 This problem is solved by installing a device for automatically closing the clip of the shutter of the tank gun on the cannon guard when the collective protection system is activated, consisting of an electromagnet and a gear rack, which is constantly engaged with the axis of the drive for manually resetting the ejectors.

 For the practical implementation of the proposed device in the well-known collective protection system, an electromagnet is connected to the automation unit B11-5-2C1 of the ZETs11-3 equipment via a rotating contact device, connected via a gear rack to the axis of the drive for manually resetting the ejectors.

 The invention is illustrated in FIG. 12.

 FIG. 1. The system of collective protection of the tank.

 FIG. 2. The system of collective protection of the tank. A device for automatically closing a wedge of a tank gun shutter.

 In FIG. 1, 2 shown: battery switch - 1; automation unit B11-5-2C1 of the equipment ZETs11-3 - 2; shield control devices of the driver-3; relay box KRP-1 - 4; gamma sensor GD-1M -5; electromagnet of blinds - 6; control panel and alarm P11-5 - 7; temperature sensors (seven pieces) - 8; manual duplication button - 9; electrical unit - 10; rotating contact device - 11; engine stop mechanism - 12; device for automatically closing the wedge of the shutter of the tank gun - 13; gun guard - 14; an electromagnet - 15; the axis of the two shoulders of the lever - 16; two shoulders lever - 17; gear rack - 18; gear rack mounting - 19; the gear sector of the axis of the drive for manual resetting of ejectors - 20; cams of a drive of manual dumping of ejectors of a lock wedge - 21; the axis of the drive for manually resetting the ejectors is 22.

 Battery switch (1) - is designed to connect a collective protection system to the on-board network of the tank.

 The automation unit B11-5-2C1 of the equipment ZETs11-3 (2) - for issuing a command to the executive mechanisms of the collective protection system by a signal from a gamma sensor, temperature sensors and manual duplication buttons.

 On the dashboard of the control devices of the driver-driver (3) are placed control devices.

 Relay box KRP-1 (4) - is intended for switching voltage of the equipment ZETs11-3 and gamma sensor.

 GD-1M gamma sensor (5) - used to signal the actuation of actuators of the collective defense system in a nuclear explosion before the arrival of the shock wave.

 Electromagnet of blinds (6) - is intended for automatic closing of blinds during a nuclear explosion.

 Remote control and alarm P11-5 (7) - used to monitor the health of the protection system, alarm and manual duplication of the signal "Fire".

 Thermal sensors (8) - designed for fire alarm.

 Manual duplication button (9) - to turn on the collective protection system manually in anticipation of a nuclear explosion.

 Rotating contact device (11) - is used to power the tower.

 Engine stop mechanism (12) - designed to automatically stop the engine.

 The device for automatically closing the wedge of the shutter of the tank gun (13) - is used to automatically close the wedge of the shutter when the collective protection system is triggered.

 All devices have an electrical and mechanical connection. So the automation unit B11-5-2C1 (2) has an electrical connection with the battery switch (1), temperature sensors (8), the engine stop mechanism (12), the shield of the control devices of the driver (3), the electromagnet shutters (6), a relay box (4), a gamma sensor (5) through a relay box (4), a control and alarm panel (7) and through a rotating contact device (11) with an electromagnet (15) for the automatic closing of the tank gun shutter wedge (13), as well as with an electrical unit (10).

 The electromagnet (15) of the device for automatically closing the wedge of the tank gun’s shutter (13) is mechanically connected to the axis of the drive for manually dropping the ejectors (22) through the two-arm lever (17), mounted on the gun guard (14) with mountings (19) toothed rack (18) and toothed sector (20).

 The collective protection system is ready for operation when the battery switch is turned on. At the same time, the collective protection system circuit is powered by electricity.

At the same time, system operation options are possible:
1. The wedge of the shutter is open: during a nuclear explosion, the signal is supplied from the GD-1M device through the relay box КРП-1, the automation unit B11-5-2С1 to the electromagnet of the device for automatically closing the shutter wedge, the operation of which closes the shutter wedge (Operation automatically).

 2. The wedge of the shutter is closed: during a nuclear explosion, the signal is supplied from the GD-1M device through the relay box КРП-1, the automation unit B11-5-2С1 to the electromagnet of the device for automatically closing the shutter wedge, while the device operates "idle" (Operation automatically )

 In anticipation of a nuclear explosion, the driver presses the manual duplication button on the relay box KRP-1, thereby issuing a command to trigger the automatic closing of the shutter wedge (Manual operation).

 If the enemy uses nuclear weapons, the GD-1M gamma sensor is triggered and sends a signal through the KRP-1 relay box to the automation unit B11-5-2C1 of the ZETs11-3 equipment, which sends a command to the electromagnet of the tank gun shutter wedge closing device. In this case, the shutter wedge will be closed automatically.

 If the shutter wedge was closed, the device for automatically closing the shutter wedge of the tank gun will work "idle".

 In anticipation of the use of nuclear weapons by the enemy, the driver can send a signal to the electromagnet of the automatic closing device for the wedge of the tank gun’s shutter manually by pressing the manual duplication button located on the relay box KRP-1.

 The introduction of the proposed collective defense system will increase the survivability of the tank on the battlefield and significantly reduce the loss of crew members from nuclear weapons.
