Description

The invention relates to the field of safe means of blasting, namely detonators with programmable time delay, and can be used as a means of initiation during blasting operations.

A device described in the patent for the invention №2156945, IPC F42B 3/10, F42C 19/08, publ. 09/27/2000 under the name “Detonator without primary explosive”, containing a body, an igniter element sequentially arranged in it, a narrow part of an intermediate shell of different section facing it, a charge of a blasting explosive of low density, a charge of blasting explosive of high density. The intermediate shell is made in the form of coaxial cylinders with a diameter increasing in the direction of high explosive high density explosive, while the narrow part of the intermediate envelope is filled with an incendiary composition that is separated by an indestructible membrane from the following igniter composition followed by a charge of low density explosive located as in intermediate the shell, and in the detonator housing before charging a high-density blasting explosive.

The disadvantage of this device is:

- difficulty in manufacturing;

- lack of possibility of programming (response time);

- long duration of the ignition process.

A device is also known that contains successively located in a housing: the charge of a pressed high explosive; charge blasting explosives with bulk density; the charge of the initiating explosive and the ignition unit (HC), the latter is made in the form of a metal spiral connected to an electronic module, described in patent for invention No. 2147365, IPC F42B 3/10, F42C 19/08, publ. 04/10/2000, under the name "detonating device".

The disadvantages of the known detonating device are:

- difficulty in manufacturing;

- use in the device of the initiating explosive, which increases the danger in handling it;

- increased energy consumption due to the use in its design of a metal spiral.

The closest and chosen as a prototype is a device that contains a case and placed in it successively an output charge of a blasting explosive, an initiating device connected to an electronic unit and containing an explosive charge, made in the form of hinges, described in the RF patent №2211435, IPC F42B 3 / 10, F42C 19/08, publ. 08.27.2003 under the name "Detonating device".

The disadvantages of the device include:

- difficulty in manufacturing;

- use in the device of the initiating explosive, which increases the danger in handling it;

- increased energy consumption due to the use in its design of a metal spiral.

The objective of the invention is to improve and expand the operational capabilities of the proposed device, namely the implementation of the exact response time of the device and the ability to carry out remote testing of the device, while improving its technical characteristics: to improve the accuracy of the response time, resistance to mechanical and electromagnetic influences, static electricity and safety in fire conditions.

The technical result of the present invention is the ability to implement the exact response time of the programmable detonator, reducing the response time of the detonator (no more than 20 μs) and remotely check the device’s performance, ensure safety when working with the detonator due to the absence of initiating explosives (IHV) and the use of secondary explosives, increased resistance to mechanical and electromagnetic effects, static discharges and safety in fire conditions, and kzhe of expansion of operational opportunities due to accomplishment of the initiator in various options.

This is achieved by the fact that in a programmable detonator comprising a housing and an output charge of a blasting explosive placed in it sequentially, an initiating device connected to the electronic unit and containing an explosive charge made in the form of hinges, according to the invention, the initiating device is made in the form of a detonator unit placed in the sleeve installed in the housing of the programmable detonator, connected to the electronic unit through the connecting element, contains the initiator, the output linkage from the high explosive and at least two x initiating attachments of blasting explosives and is bordered by the output charge of blasting explosives.

In addition, the initiator of the detonator unit is made semiconductor.

In addition, the initiator of the detonator unit is made optical (laser).

In addition, the initiator of the detonator unit is made of bridged wire.

In addition, the initiator of the detonator unit is made of shock-wave.

In addition, the connecting element is designed as conclusions.

In addition, the connecting element is designed as a connector.

The presence in the claimed invention of features that distinguish it from the prototype, allows us to consider it to be consistent with the condition of "novelty."

New features (in a programmable detonator the initiating device is made in the form of a detonator unit placed in a sleeve installed in the housing of the programmable detonator, connected to the electronic unit through a connecting element, contains the initiator, the output linkage from the high explosives and at least two initiating suspensions from the high explosives and bordered by the output charge of blasting explosives) not identified in the technical solutions of a similar purpose. On this basis, it is possible to draw a conclusion on the compliance of the claimed invention with the term “inventive step”.

The invention is illustrated in the drawing, which shows a General view of the programmable detonator and marked the following positions:

1 - case

2 - output explosive charge

3 - sleeve,

4 - output charge BB,

5 - initiating hinge explosives,

6 - initiator

7 - connecting element

8 - electronic unit

In case 1, an output charge 2, an initiating device consisting of explosive hinges and connected to an electronic unit 8 through a connecting element 7, made in the form of current leads or connectors, is installed in series. The initiating device is made in the form of a detonator unit consisting of a sleeve 3 with an output link 4 of blasting explosives pressed into it, bordered by an output charge of 2 blasting explosives, and initiating hanging 5 of blasting explosives, and the initiator 6.

Programmable detonator works as follows.

When applying a disruptive electric pulse from the electronic unit 8, programmed for a certain response time to the initiating device, the initiator 6 is triggered, which activates the initiating suspensions 5 from the high explosive (bypassing the stage of convective combustion, a high-speed deflagration (explosive) transformation quickly in detonation) and sequential operation (detonation) of the output linkage 4 of the high explosive and the output charge 2 high explosive.

An example of a specific implementation is a programmable detonator containing pressed sequentially into the sleeve 3, which borders on the output charge 2 of blasting explosives (HKT), output hitch 4, made of blasting explosives (PETN) and at least two initiating hangings 5, made of blasting explosives , namely, diperchlorate (5-nitrotetrazolato) pentaamine cobalt (III). One of the initiating hinges 5 is associated with the initiator 6, made, for example, in the form of a housing (not shown) with an integrated semiconductor energy conversion device (PES) consisting of an exploding bridge of semiconductor structures formed on a dielectric substrate fixed in a sleeve 3 , for example, by laser welding. The initiator 6, connected to the electronic unit 8 through the connecting element 7, made in the form of conclusions, the sleeve 3 with hinges BB 5 and 4, the output charge 2 are located in the housing 1, rolled in the area of the seal (not shown), to ensure tightness and eliminating the possibility of axial movement of elements of a programmable detonator. In addition, the company conducted successful laboratory tests of a programmable detonator having an initiator 6, made optical (laser) or shock-wave. In addition, the connecting element 7 in the laboratory tests of a programmable detonator was made in the form of a connector.

The use of this invention will allow:

- to increase safety when working with a programmable detonator due to the absence of an initiating explosive in its structure;

- to ensure high accuracy of time characteristics (response time, time delay step)

- reduce the time of operation of the detonator and the step of the time delay of blasting due to the absence of igniter composition;

- reduce the energy of operation of the explosive device,

- improve its weight and size characteristics,

- improve and expand the operational capabilities of the programmable detonator by performing the initiator in various ways.

Thus, a programmable detonator embodied in the claimed invention, in its implementation, is capable of ensuring the achievement of a technical result perceived by the applicant. Therefore, the claimed invention meets the condition of "industrial applicability".
