Description

The proposed utility model relates to the field of information and explosive technology, as well as to storage and transportation systems, namely, to systems of transportation, storage and protection of information contained on optical and magneto-optical disks from unauthorized access through explosive destruction of information carriers.

A device for transportation and emergency destruction of confidential information carriers is known, based on a thermochemical method of destroying information carriers (Boborykin S.N., Ryzhikov S.S. “Thermochemical Destruction of Information Drives”, magazine “Special equipment”, No. 2, 2002, pp. 46-50). It consists of a container for storage of information carriers with double walls, made of heat-resistant material and of thermite composition located between the walls of briquettes connected by a common system of destruction initiation. In the event of a danger of unauthorized access to the transported documents, the transporting party activates the system of initiating destruction, and under the influence of high-temperature products of burning briquettes of thermite composition, physical destruction of information carriers occurs. The main disadvantage of this device is its low speed - up to several minutes.

The protective system is also known for transporting and preventing unauthorized access to information contained on transported information carriers - CDs, cassettes or 3.5-inch diskettes (US Patent No. 4931770, published 05.06.1990). This system contains a case in the form of a rectangular parallelepiped with rounded edges and with a hinged lid located on top and with a locking mortise lock, a storage system for the information carrier, which is a wire frame made in the form of a carrier and rigidly fixed inside the system case information located opposite the carrier being transported and consisting of an abrasive wheel rigidly mounted on the shaft of the electric motor that sets the rotational movement to uh huh and rails, on which an electric motor with abrasive wheel can move in the direction of the carrier, with an external activation system activation button located on the apparatus body and a power source, fixed in the inner space of the system housing and electrically connected by wires to other circuit elements. When a danger of unauthorized access to the transported disks occurs, the destruction system is activated, as a result of which the rotary movement is attached to the abrasive disk and along the guides it moves closer to the information carrier being deleted, and the layer with the recorded information is erased.

The disadvantages of this device are:

- technical complexity;

- the system is designed to transport and store only one CD;

- low destruction rate - up to several minutes.

The closest to the proposed known technical solution as a prototype is a shredder of confidential information disk media (Patent RU 86494, IPC В02С 19/18, 2009) containing an electric igniter, a cylindrical working chamber with a threaded closing lid and a chord hole leading into the cylindrical a working chamber with an installed guide pin in its center, and a sleeve with a removable powder accumulator of gases, installed on the outside of the chord hole, using an electric the igniter undermines the charge of the powder gas accumulator. When the powder charge of the gas accumulator is blown up, a shock wave is generated, which, moving first along the chord and then along the spiral line inside the cylindrical working chamber, destroys confidential information compact discs that were previously laid (strung) on a pin installed in the center of the cylindrical working chamber. chambers, for their crushing.

The disadvantages of this utility model are:

- using a powder charge as a source of a shock wave does not allow to achieve the required pressure values at the front of the shock wave ΔРф for crushing the transported disks to fragments, the value of which is guaranteed not to allow data from them to be recovered;

- the connection of the end cap with the cylindrical chamber body only by a threaded joint in the case of using a more powerful shock-wave initiating device can lead to the breakdown of this cap.

In connection with the different designations of the same details of the proposed utility model in various sources, we will bring their name to a common technical terminology. "Guide pin" from the description of the prototype we denote as "pillar", "transitional washers" as "intermediate sleeves". The term “Cylindrical working chamber” will be opened as “a cylindrical body with an open top part and a closed bottom”.

The essence of the utility model is that the storage device and emergency destruction of optical and magneto-optical disks, containing a cylindrical body with an open upper part and a closed bottom, with a mounted rod stand in its center, on which are mounted portable disks, and the upper part of the cylindrical body is connected with end cap by means of a threaded connection, a cylindrical shock wave generator (BSG) is additionally introduced, rigidly attached to the central part of the cylindrical Skog body perpendicularly to its axis, and connectable to an external device initiation, the end cap is secured by thumb screw threaded connection formed by the cylindrical body axis.

This design is optimized in size for a specific task - the storage and emergency destruction of optical and magneto-optical disks, laid inside the cylindrical body.

The design of the device is shown in FIG. 1 and 2. Here: 1 - a cylindrical body, 2 - an end cap; 3 - shock wave generator; 4 - rod stand, 5 - intermediate bushings; 6 - thumb screw; 7 - locking sleeve.

A device for storing and urgently destroying information from optical and magneto-optical disks consists of a cylindrical body 1, which is perpendicular to the axis of which, on the outside, is fixed to the power supply device 3 connected to an external initiating device; transportable discs are positioned, separated from each other by fluoroplastic intermediate sleeves 5, while the number of discs transported can be varied by changing The length of the locking sleeve 7, located on the rod stand 4, which by means of the thumb screw 6 is connected to a threaded closing lid 2. All parts of the device body are made of high-strength steel. The design of BS 3 is known from the current level of technology (Patent RU No. 140420, IPC F15B 21/12, 2014, patent RU No. 154734, IPC F15B 21/12, В06В 1/02, 2015). At the same time, the intensity of the excited shock waves depends on the pressure of the medium supplied to the receiver. The higher the pressure, the higher the intensity of the shock waves.

A device for storing and emergency destruction of information from optical and magneto-optical disks operates as follows. In the event of a danger of capturing transportable discs with restricted access information, a control module located in one of the members of the accompanying group activates the BSB 3 by applying an electric impulse to the electric detonator included in its composition, and a shock wave is generated as a result of the initiation of the explosive charge , which passes through the outlet of the BS 3 into the internal volume of the cylindrical body 1, taking a hemispherical shape. Under the action of shock wave loads on the material of the disks located on the rod rack 4 and separated from each other by intermediate sleeves 5, they are physically destroyed to fragments whose dimensions do not reliably restore the information contained on them.

Thus, the proposed device for storing and urgently destroying information from optical and magneto-optical disks allows, with a sufficient degree of efficiency and efficiency, to destroy information from this type of confidential information media.

Technological execution of this device is quite simple, all components, in particular, metal-roll of various sizes, electric detonators, fasteners, explosives are produced industrially.

The use of HVG 3 as a device for initiating a shock wave will increase the efficiency of information destruction from transported disks. A device for storing and urgently destroying information from optical and magneto-optical disks allows emergency destruction of the indicated information carriers with a high degree of speed and reliability of destruction.
