Description

The invention relates to the field of development of high-precision blasting systems and can be used as part of non-electric blasting systems, initiation systems based on shock wave tubes (UVT), etc., when initiating blasting systems for blasting in the mining industry, military affairs, rescue services, etc.

Practical application is to create a safe high-precision initiation system with a given time delay of the device.

An example of safe devices for generating time delays during initiation is the application for the invention RU 2008117494, 04/30/2008, in which a pyrotechnic relay of increased accuracy for tripping is proposed, however, creation of accurate deceleration intervals is possible only when using electronic detonators with electronic deceleration (US Pat. No. 6173651 from 2001 [1], Russia №21473 65 [2], 2211435 [3] and others), in which the required deceleration time is programmed before the explosion, and the accuracy of the time intervals is ~ 1 ms, in the range from 0 to 20 s. The cost of such systems (see www.rica.com) exceeds $ 20 or more.

Closest to the proposed device is a detonator capsule with an electronic delay (RF patent No. 2349867) containing a housing in which are located: an igniter, an electronic blast delay assembly ... programmed in the manufacture for a fixed deceleration time, and also the device according to patent No. DE 4427296 / 0A1 and patent No. US 6814005 B1, containing as a source of power node delay and initiation of galvanic cells.

The objective of the invention is to create a cheap, reliable, safe, quickly programmable before the explosion of the digital delay module of the non-electric blasting system, which is switched on by a pulse initiating UHT.

The technical result of the invention is the creation of a safe design of a device for switching and initiating an electric moderator, which ensures the initiation of a shock wave with a delay in the movement of its pulse.

The technical result is achieved by the constructive implementation of the device for switching and initiating the UHT with an electronic chronometer without the use of explosives.

The problem is solved due to the fact that the programmable digital delay module of the non-electric blasting system (module) contains a housing in which the igniter is located, an electronic node of the programmable delay of the igniter operation, UHT clamp-inputs, a power supply of the electronic node of the programmable delay of switching on via the key-sensor igniter and UHT connected to the instant detonator capsule, triggered when the igniter is triggered, in addition, the housing is equipped with roofs Second, through which, after programming, through the open key sensor inserted power supply providing, when activated, sensor key, the power supply of the electronic assembly and the ignition power supply.

The device description is illustrated by the module diagram shown in the drawing, where: 1 - module housing, 2 - igniter, 3 - programmable delay electronic assembly, 4 - UVT input-clamps, 5 - sensor key, 6 - power supply, 7 - UVT, 8 - lid-lock of the power source, 9 - electronic key, 10 - indicator of module activity, 11 - sealing plug, 12 - instant-action detonator capsule.

The device operates as follows.

Before using module 1, with the cover open 8, the electronic delay unit 3 is programmed, then through the input 4, using the sealing plug 11, the start segment of the UVT 7 is fixed, immediately before the blasting, the module is connected by galvanic connection, through open key 5, the power supply 6 (a galvanic cell, an ionistor, etc.), which is indicated by the activity indicator 10, closes the latch-latch 8 and connects the second section of the UVT with an instant detonator capsule 12. P When initiating the start segment of the UHT 7, the key sensor 5 is triggered, starting with the electronic key 9 a programmable delay unit 3, the operation of which ends with the start of the igniter 2, which initiates the UHT 7 and the detonator capsule 12, which completes the operation of the device of the non-electric explosion system.

Implementation of the module as a separate unit allows you to secure blasting operations, storage and transportation conditions, since without a power source it is equivalent in degree of danger to a single match head. The possibility, with the lid open, of programming the deceleration time, ensures the speed of making adjustments to the scheme for blasting the face, block, etc. under changing mining and geological and other conditions. Placing a power source in the module immediately before the explosion significantly increases the reliability of the system, eliminating the appearance of discharged sources during long-term storage in non-separable modules. The short duration of operation of power sources allows the use of cheap single-use elements, while the possibility of using an ionistor, magneto-induction, piezoelectric and other current generators used in the prototypes is not excluded, significantly reducing the cost of the module. Thus, the proposed device and method of its application performs all the tasks.
