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
контактом, например с подпружиненным контактным штыред.contact, for example with a spring-loaded contact pin.
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
электродетонатором.electric detonator.
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.
