Description

Technology area

The invention relates to logical explosive devices. More specifically, for devices that implement logical operations using an explosion, and can be used in explosive systems, to which high safety requirements are imposed to protect detonation firing circuits in case of accidental or unauthorized actions.

Prior art

The known device is described in the patent of the Russian Federation No. 2542804 "Detonation logic device for the formation of a blast wave", IPC F42B 3/10; application: No. 2013152817/11, priority 27.11.2013; published on February 27, 2015, authors: Osiptsov Alexander Petrovich (RU), Zubanov Alexander Vladimirovich (RU).

The features of the analogue, coinciding with the essential features of the invention, are as follows. Detonation logic device for the formation of a blast wave, containing a housing in which the main charge of explosives and a matrix of inert material are located, with a network of channels and holes filled with explosives, having an initiation point, a matrix of inert material with a network of channels and holes filled with its own initiation point.

The disadvantage of this device is the complexity of the automation system, since it is designed to excite detonation in explosives with reduced sensitivity, and for the normal operation of this device, it is necessary to issue two synchronous pulses.

You know the device described in the patent of the Russian Federation No. 2247923 "Explosive logic circuit", IPC F42B 3/10, application No. 2003124686/02, priority 07.08.2003, published 10.03.2005, authors: German V.N. (RU), Orlikov Yu.P. (RU), Alexandrova S.A. (RU), Dendenkov Yu.P. (RU), Fisenko A.K. (RU).

Explosive logic circuit containing a board with two inputs and one output, interconnected by detonation rods, forming a long and short branches between the first input and the output, with the second input being connected to the short branch, while at the joints of the long with a short branch and a short branch with the second the input installed actuating elements that destroy the detonation connection, characterized in that the detonation rods are placed on both sides of the board, and through holes are made in the board, in which the actuators are installed that destroy the detonation connection, made in the form of a receiving charge and an inert barrier adjacent to it, placed on the side of the detonation rod to be destroyed with the ability to move under the action of the explosion products of the receiving charge, and the detonation channels and the receiving charge are made of the deposited explosive.

The features of the analogue, coinciding with the essential features of the invention, are as follows. Explosive logic circuit containing a board with two inputs and one output, interconnected by detonation rods, forming a long and short branches between the first input and the output.

The disadvantage of this explosive logic circuit is the need to accurately calculate the minimum difference in the lengths of the short and long sections, if violated, the circuit may not work in normal mode. Its principle of operation is based on the destruction of a long rod, along which detonation is transmitted to the exit, due to the effect of detonation propagating along an additional short path. That is, it is necessary to ensure a certain minimum difference in the lengths of the short and long sections, so that the detonation propagating along the short bar has time to destroy the long bar.

As a prototype was chosen the closest in technical essence to the claimed device RF patent No. 2335732 "Explosive logic device", IPC F42B 3/10, F42D 1/04, Application: 2005100137/02, priority: 11.01.2005; published on 10.10.2008, authors: Gorelik Zakhar Abramovich (RU), Ovcharov Igor Vladimirovich (RU), Semenov Boris Pavlovich (RU), Senkin Alexander Nikolaevich (RU), Shchutsky Aleksey Anatolyevich (RU).

The explosive logic device contains a detonation circuit, a blocking circuit, a blocking release circuit, an explosive circuit branching unit and explosive valves, the first of which is located in the blocking circuit between the branching unit connected to the first input of the explosive logic device and the output of the explosive logic device. The second explosive valve is located in the detonation circuit between the branching unit and the control input of the first explosive valve, and the first explosive valve is connected by a blocking release circuit with the second input of the explosive logic device. The blocking chain and the blocking release chain are made in the form of detonating cords with a plastic explosive core enclosed in a metal sheath, and the outer diameter of the metal sheath is equal to two diameters of the cord core.

The features of the prototype that coincide with the essential features of the invention are as follows. The explosive logic device containing the detonation circuit, the interlock circuit, the interlock circuit, the interlock circuit and the interlock circuit are made of a plastic explosive.

The disadvantage of this device is the insufficient explosion safety of the logic device, due to the presence of an extended dangerous section of the DGHF, an unauthorized detonation of which will lead to the activation of the main charge. The length of this section must additionally include the response time of the valve F, which increases the length of this dangerous section. The use of a detonation cord in metal tubes, as well as additional elements in the form of detonation valves, requires the introduction of additional fasteners and docking connections that increase the dimensions of the logic device and reduce its reliability.

Disclosure of invention

The task to be solved by the claimed invention is the creation of an explosive logic device with increased explosion safety, reliability, with reduced weight and size characteristics for products containing explosives.

The technical result achieved when solving this problem is to reduce the length of the dangerous section, the detonation of which leads to the activation of the main charge, as well as in the placement of all elements of the explosive logic device in the dimensions of one inert pad, in the exclusion of metal tubes and valves from the circuit of the explosive logic device ...

The technical result is achieved by the fact that in an explosive logic device containing an input, an output, a detonation circuit, a blocking circuit, a blocking release chain, a blocking chain and a blocking release chain are made of a plastic explosive in the form of detonation rods, according to the invention, the detonation chain is combined with a blocking chain , the detonation rods are enclosed in a pad of inert material, the output of the explosive logic device is made in the form of a rod of a plastic explosive enclosed in a metal sleeve and an adjacent detonation rod.

Implementation of the entire device in a pad of inert material containing detonation wiring in the form of rods of explosive composition in detonation channels ensures reliable operation.

Detonation paths in the form of rods of explosives of the explosive logic device are designed in such a way that when the main detonation path is initiated, without activating the interrupting detonation path, there is no detonation signal at the output of the explosive logic device, thus ensuring the safety of detonation chains of detonation during accidental or unauthorized actions.

Execution of the main detonation path, when the interrupting detonation path is triggered, provides the formation of simultaneous detonation signals from the source of initiation to the explosive bar placed in the metal sleeve. The simultaneous front of detonation signals in the area of the bushing ensures reliable initiation of the explosive rod placed in the metal bushing. In the absence of activating the interrupting detonation path, detonation signals in the area of the sleeve pass with a time difference, due to this, the wall of the sleeve is preserved, and the detonation signal is not transmitted to the explosive composition bar, placed on the sleeve, without using the main explosive of the product.

Thus, the set of essential features provides the creation of an explosive logic device with increased explosion safety, reliability, with reduced weight and size characteristics for products containing explosives.

Brief Description of the Drawings The invention is illustrated by the following drawings: FIG. 1 shows a general view of an explosive logic device, FIG. 2 shows section AA.

Embodiments of the invention

Explosive logic device (Fig. 1), contains a pad 1 of an inert material, an inlet in the form of a rod 2, made of an explosive. Rod 2 is located perpendicular to the plane of the pad 1. Detonation rods 2, 5, 6-19 are fixed in the pad 1 of inert material.

The outlet, in the form of a bar 3, is located perpendicular to the plane of the lining 1. The bar 3 is made of an explosive and passes through a metal sleeve 4. A detonation bar 15 adjoins the sleeve 4 from the outside.

The blocking chain consists of rods 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and is configured to conduct or block a signal. When the blocking release chain is activated, the blocking chain is designed to initiate the bar 3 surrounded by a metal bushing 4. The bushing 4 is installed in the lining 1 made of inert material by means of an adhesive joint.

The blocking release chain consists of a bar 18 located on the back side of the lining 1. At the inlet of the bar 18 there is a receiving bar 19 located perpendicular to the plane of the lining 1. The blocking release chain is interrupted in the bar 16 at section 20. The blocking release chain in the form of a bar 18 and a bar 19, when triggered, interrupts the blocking circuit in bar 16 in section 20.

The blocking chain and the blocking chain are made of rods consisting of a plastic explosive.

The bushing 4 contains a wall 21, which is adjoined by a detonation rod 15 on one side and a rod 3 on the other side.

Interruption of the blocking circuit in the bar 16 in the section 20 ensures the synchronization of the detonation signals in the bar 15. As a result, the wall 21 of the sleeve 4 breaks through, initiating the bar 3.

In case of emergency and unauthorized influences on the explosive logic device, the dangerous section is the bar 7 and part of the bar 6. In the claimed device, in comparison with the prototype, the hazardous section in the explosive logic device occupies a much shorter length. A decrease in the size of the hazardous area leads to a decrease in the probability of transmission of a detonation signal to rod 3 from the bullet-fragmentation effects along the main detonation path, and, therefore, leads to an increase in the explosion safety of products containing explosives.

The assembly of the claimed device is carried out as follows.

A metal sleeve 4 is installed and glued into the hole of the lining 1 made of inert material 4. Then, rods 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 are placed in the grooves of the lining 1. the holes of the lining 1 insert the rods 2 and 19, and the rod 3 into the hole in the sleeve 4. The device is assembled and ready for use.

The implementation of the entire device in a strip 1 of inert material containing detonation wiring in the form of rods of explosive composition in the detonation channels ensures the reliability of the device. Each element in the explosive logic device reduces its overall reliability. In comparison with the prototype, where there are metal tubes and valves, they are not in the claimed explosive logic device. This leads to an increase in the reliability of the claimed explosive logic device in comparison with the prototype, as well as to a decrease in weight and size characteristics.

The device works as follows.

Before the blocking circuit is initiated, the blocking release chain is initiated in the form of a bar 19, the detonation signal passes through the bar 18 and in section 20 interrupts the detonation path in the bar 16. Next, bar 2 is initiated, the detonation signals pass along the bars 5, 6, 7, 8, 9, 12, 10, 13, 11, 14, are found in the bar 15, and with a synchronous front, the detonation wave destroys the wall 21 of the sleeve 4, thereby initiating the explosive bar 3.

In case of emergency, unauthorized or erroneous actions in the blocking circuit when the blocking release chain is not used, bar 16 is not interrupted in section 20. If you further initiate bar 2, then the signal will go along bars 5, 6, 7, 8, 9, 10, 11 and along rods 5, 16, 17, 12, 13, 14. The signals, having reached the rod 15, do not form a synchronous front, since the length of their paths is different.

The danger is the unauthorized use of the bar 7 and part of the bar 6, as a result of a bullet-fragmentation effect. In this case, a detonation pulse is formed, which is able to form detonation signals, which, having passed in two ways, the rods 8, 9, 10, 11 and 8, 12, 13, 14, meet in the rod 15, and the detonation wave with a synchronous front destroys the wall 21 of the sleeve 4, thus thus initiates the explosive bar 3. However, in comparison with the prototype, the size of the hazardous area 7 and part of the bar 6 is much smaller. This makes it possible to draw a conclusion about the increase in explosion safety, the reliability of the explosive logical device as a whole in case of emergency, erroneous or unauthorized actions.

The enterprise produced and tested prototypes, which confirmed the performance of the proposed device. The specified device can be used in the development of military equipment, explosive devices, for use in economic activities (engineering charges, mining, mechanical engineering, etc.), research activities, where requirements are imposed on ensuring the safety of operation of products containing explosives, reduction of weight and size characteristics, ease of manufacture and ensuring the reliability of the explosive automation of the initiation system.
