Abstract

Предложено извлекаемое устройство (10) трубопрочистного ерша, имеющее, по существу, цилиндрический корпус (32), причем этот корпус (32) имеет сквозной центральный проточный канал (34) и прикреплен к гибкой трубе (22), свертываемой в бухту, и при этом центральный проточный канал (34) текучей среды сообщается посредством текучей среды с внутренним каналом (35) гибкой трубы, свертываемой в бухту; при этом предусмотрена совокупность проточных каналов (40), равноотстоящих друг от друга внутри корпуса, причем эти проточные каналы (40) обеспечивают протекание текучей среды, нагнетаемой под предварительно определенным давлением, по проточным каналам с обеспечением ее выпуска на переднем конце трубопрочистного ерша для образования струи высокого давления, предназначенной для разрушения возникших в трубопроводе пробок обломочного материала (70), такого как парафин и т.п.; при этом обломочный материал (70) удаляют по центральному каналу (34) обратно в гибкую трубу, свертываемую в бухту, для сбора в резервуаре (157) и т.п. на поверхности. Также имеется совокупность гибких манжет (24), которые отстоят друг от друга вдоль внешней стенки корпуса (25) трубопрочистного ерша, причем каждая манжета (24) прикреплена к внутреннему металлическому кольцу (26) вокруг корпуса (25) трубопрочистного ерша, при этом гибкие манжеты (24) вступают в контакт со стенкой (13) трубопровода для обеспечения постоянного гидравлического уплотнения между стенкой (13) трубопровода и концами совокупности гибких манжет (24). Между каждыми соседними манжетами (24) имеется сжимаемое предохранительное кольцо (28), которое сжимается под действием избыточного давления в трубопроводе, обеспечивая тем самым протекание текучей среды мимо
