Abstract

The invention discloses a waterproof safe detonation transmission pipe, and belongs to the field of blasting operation. The purpose of the waterproof safe detonation transmission pipe is to solve theproblems of poor sealing performance and poor safety of existing detonation transmission pipes. The waterproof safe detonation transmission pipe comprises a main detonation transmission pipe shell anda sealing shell, the sealing shell is arranged at the upper end of the main detonation transmission pipe shell, and the lower end of the sealing shell is closed and the upper end of the sealing shellis open. An annular lower groove is formed in the outer side wall of the lower end of the sealing shell, and a high-temperature O-shaped ring is arranged in the lower groove. An annular protrusion isarranged on the inner side wall of the sealing shell, and the annular projection is matched with a clamping groove on a detonating cord. The waterproof safe detonation transmission pipe is resistantto high temperature and high pressure and is waterproof; and the detonating cord is connected by a direct-insertion and counter-lock mode and is not prone to falling off.

Description

technical field [0001] The invention belongs to the field of blasting operations, and in particular relates to a waterproof safety detonator tube. Background technique [0002] In the blasting process of oil and gas well perforating operations, geological underground mineral mining, and open-pit blasting, the blasting tube is one of the most critical links. Without a stable and reliable blasting tube, the explosion energy cannot be successfully transmitted. The entire blasting The system will break off and reject the explosion phenomenon, resulting in the failure of the explosion operation or accident. Only by adopting safe and reliable detonating tubes to transmit the explosive energy continuously, all medium-fire workpiece perforating bullets, synergistic charges, detonating cords, secondary detonating devices, and charge packs during the detonation process can obtain detonation energy and be recognized. Detonation, sacrifice, play its blasting effectiveness. [0003] Ex...
