Underwater induced detonation experiment device and using method thereof

Abstract

The invention provides an underwater induced detonation experiment device which comprises an explosive loading and hoisting system, a pressure testing system and a witness target testing system. The explosive loading and hoisting system comprises a hoisting frame, a main launching loaded explosive, a detonation device and a launched loaded explosive. The main launching loaded explosive and the launched loaded explosive are arranged in the hoisting frame, and the detonation device is arranged on the main launching loaded explosive; the pressure testing system comprises a pressure sensor and a data acquisition instrument, the pressure sensor is connected with the data acquisition instrument, and the pressure sensor is arranged on the periphery of the explosive loading and hoisting system; the witness target testing system is of a witness target structure. More information for judging sympathetic detonation or not and the degree can be recorded, collected and analyzed mainly through cooperation of the explosive loading and hoisting system, the pressure testing system and the witness target testing system, so that multiple effective evaluation ways can be provided for evaluation of sympathetic detonation in water.

Description

technical field [0001] The invention relates to the technical field of underwater blasting, in particular to an underwater blasting experiment device. Background technique [0002] At present, there are few public documents on the problem of detonation in water, and there are many researches on the detonation of explosives in air at home and abroad. For the air explosion, whether there is residual powder or residual shell at the place where the charged charge is placed, the damage of the witness plate, and the shock wave pressure are the main methods to judge whether the charged charge is exploded or not. The underwater explosion test method can refer to the air explosion, but due to the compressibility of water during the underwater explosion, the overpressure formed by the shock wave in the water is much greater than that in the air. In addition, long-term pulsating bubbles will be formed during the underwater explosion. , may also cause the sacrificial explosion of the c...

AI Technical Summary

Problems solved by technology

At present, for the detonation experiment in water, the peak pressure of the shock wave at the measuring point and the bubble period are used to judge whether the charge is detonated. If it is destroyed during the underwater explosion, it will not be able to record the complete pressure time-history curve, bubble pulsation period and other physical quantities, and it will not be possible to fully evaluate whether the explosion in water is complete or not.
