Description

The utility model relates to the field of military equipment, namely to the safety-cocking mechanisms of cluster engineering munitions.

Known anti-personnel cluster mines POM-2 (prototype) [1, 2] and POM-3 [3], in which the transfer of mines to the combat position is as follows: when an electrical impulse is supplied to the ECV-30M electro-capsule bushing, the capsule composition fires, which ignites powder explosive charge of the cartridge, as a result of which the block with mines is ejected from the cartridge. The separation of the block with mines occurs on the flight path by the pressure of the powder gases of the separation charges, which are ignited by the pulse of pyrotechnic moderators. The supply of powder gases from pyrotechnic moderators is carried out through gas pipes. Before the block with mines from the cassette exits, the channels of the gas pipes are blocked by spring-loaded rods (the first stage of protection of the safety-cocking mechanism), which are released after the block with mines exit the cassette. After the separation of the block, the mines are scattered on the ground and transferred to the combat position in the target standby mode.

The disadvantage of the safety-cocking mechanisms of these engineering munitions is that they do not ensure the safety of cartridges with mines when they enter the fire zone (fire) during storage or transportation. The capsule composition, which is part of the EKV-30M, and the powder charge in these engineering munitions are sensitive to high temperature, which contributes to the release of a mine block when exposed to open fire on the cartridge, which in turn leads to their transfer to the combat position. Thus, in the event of a cluster munition falling into the ignition zone, it is highly likely that mines can be fired from cartridges and put into combat position, resulting in unintentional mining of the adjacent territory.

The technical result, which the utility model is aimed at, is the inclusion of a cocking blocking device in the safety-cocking mechanism, which will eliminate the removal of the first stage of protection of cassette engineering mines in the event of an abnormal (when exposed to open fire) operation of the powder expelling charge of the cartridge.

The technical result is achieved by the fact that in the safety-cocking mechanism of cluster engineering munitions at the first stage of protection, an additional device for blocking the loading of cluster mines in case of fire is additionally installed, including: a housing, a movable locking means (option, in the form of a plunger) installed in the housing with rotation and / or longitudinal movement in the housing, the fixing means for fixing the locking means in the housing, which is moved by the actuator, is located nnym in the locking device.

As an actuator in the device, any of the groups is used: a solenoid, an electric motor, a piezomotor, electrostatic mechanisms, etc. The placement of the actuator in the locking device simplifies the communication of the device elements and ensures its compactness. The movable locking device is moved by the actuator located in it, an impulse from an electrically connected to it, through the wiring harness of the ECV-30M cartridge capsule.

To remove the lock from the first stage of protection of the safety-cocking mechanism of the unit with mines, an electrical impulse is required on the ECV-30M cartridge capsule. In the absence of an electrical impulse, when the cartridge detonating charge is triggered by external influences (open flame), the blocking from the first stage of protection is not removed.

The figure 1 shows a functional diagram of a cartridge with a cocking locking device, containing an ECV-30M electro-capsule sleeve (1), expelling powder charge (2), temperature and pressure sensors (3) and a safety cocking mechanism with a cocking locking device (4).

The figure 2 shows a functional diagram of a cocking locking device containing a locking means (5) installed in the housing with the possibility of rotation and / or longitudinal movement. A locking means (6) (balls or rollers) is provided in the locking means for locking the movement or fixing the locking means in the housing by force. The actuator (7) is also located in the locking means. The actuator is parallelly connected by electric wires to the ECV-30M cartridge capsule.

The operation of the claimed device blocking cocking is as follows.

When storing the cartridge in storage conditions, the cocking blocking device blocks the rods that cover the gas ducts intended to transmit the force of fire from the pyrotechnic amplifiers to the separation charges of the min unit. When a standard electrical impulse is supplied (from a portable mining kit or from the side of a mine trap) to the ECV-30M electro-capsule sleeve (using a cartridge for mining the terrain), the lock is removed from the rods, as a result of which the cartridge is operated and mines are put into combat position in the normal mode. In the event of an emergency (fire in the storage with engineering cluster munitions, lack of an electrical impulse to the ECV-30M electro-capsule sleeve, an abnormal firing of a block with mines, due to the operation of the powder expelling charge), the cocking blocking device prevents the rods from escaping (fire force is not transmitted to the separation charges , the removal of the first stage of protection of the safety-cocking mechanism does not occur).

The cocking blocking device will ensure that the block with mines is not cocked when they are not fired from the cartridge in case of an emergency (fire) at storage sites or during the transportation of engineering cluster munitions.
