Description

1 one

Известен корпусный кумул тивный перфоратор , содержащий секции с кумул тивными зар дами и средствами взрывани .A well-known cumulative perforator containing sections with cumulative charges and means of blasting is known.

Предложенный перфоратор отличаетс  от известного тем, что кажда  из сопр гающихс  частей секций снабжена платой, в которой размещен концевой элемент детонационной цепи и контакт электрической цепи. Концевые элементы детонационной цепи установлены с зазором. Это обеспечивает безопасность при разр дке отказавшего перфоратора, повышает производительность работы, исключает подрыв перфоратора в случае его разгерметизации.The proposed perforator differs from the known one in that each of the mating parts of the sections is provided with a plate in which the end element of the detonation circuit and the contact of the electric circuit are placed. The end elements of the detonation circuit are installed with a gap. This ensures safety when discharging a failed perforator, improves productivity, eliminates the detonation of the perforator in case of its depressurization.

На фиг, I изображен предложенный перфоратор; на фиг. 2 - места соединени  смежных секций, узел А и разрез по Б-Б. Перфоратор состоит из соединенных между собой секций 1, включа  концевую 2, закрытых сверху головкой . В каждой секции размещены кумул тивные зар ды 3, отрезок детонирующего щнура 4 и запальный электропровод, а в концевой секции - электродетонатор или взрывпатрон 5.Fig, I shows the proposed perforator; in fig. 2 - junctions of adjacent sections, node A and section along BB. The perforator consists of interconnected sections 1, including the end 2, closed on top of the head. Each section contains cumulative charges 3, a segment of detonating cable 4 and ignition electric wire, and in the end section there is an electric detonator or explosive 5.

С одного конца секции устанавливаетс  плата 6 с электрическим контактом, например, в виде кольцевой контактной пластинки 7 и гнездом, в которое вводитс  конец отрезка детонирующего шнура с шашкой взрывчатого вещества 8. Плата удерживаетс  в корпусе секции стопорным кольцом 9. С другого конца секции устанавливаетс  аналогична  плата сAt one end of the section, a board 6 is installed with an electrical contact, for example, in the form of an annular contact plate 7 and a socket into which an end of a section of a detonating cord with a bomb of explosive substance 8 is inserted. board with

Дл  исключени  подрыва перфоратора в случае его разгерметизации шашки взрывчатого вещества установлены с зазором. После свинчивани  секций подпружиненный контактный штырь 10 упираетс  в кольцевую контактную пластину и обеспечивает электрическую цепь между секци ми, включа  концевую сTo avoid undermining the perforator in the event of its depressurization, the explosives are installed with a gap. After screwing the sections, the spring-loaded contact pin 10 abuts against the annular contact plate and provides an electrical circuit between the sections, including the end

От импульса электрического тока, подаваемого по кабелю через электропровод, а затем по электрической цепи, включающей скольз щие контакты в секци х, срабатывает электродетонатор или взрывпатрон. Детонаци  от него через заданный зазор передаетс  шашке взрывчатого вещества, а затем от нее - к отрезкам детонирующего шнура и зар дам в секци х.From a pulse of electric current supplied through a cable through an electrical wire, and then through an electrical circuit, including sliding contacts in the sections, a detonator or explosive charge is triggered. Detonation from him is transmitted through a predetermined gap to the explosive bomb, and then from it to the segments of the detonating cord and charges in the sections.

В случае отказа перфоратора при отвинчивании концевой секции взрыватель, пол ещенный в нее, автоматически отключаетс  от электрической и детонационной цепей.In the event of a failure of the perforator, when unscrewing the end section, the fuse, which has already been inserted into it, is automatically disconnected from the electric and detonation circuits.
