Abstract

The invention provides an electronic detonator underwater explosive power testing device based on water hammer wave signals. During testing, an open and safe water area is selected; the testing device is assembled, an electronic detonator and an underwater shock wave sensor are arranged in an annular frame, and a detonating circuit and a signal receiving circuit are connected; the connection condition of the device is checked, and the testing device is placed in the water area after it is determined that no problem exists; the electronic detonator is detonated, the water hammer wave signals are collected through a sensor, a P-t curve is obtained, and parameters such as the underwater explosive shock wave pressure peak value are obtained; and the TNT equivalent value of the tested electronic detonator is calculated. The device is developed on the basis of the water hammer wave signals, the interference of environmental noise is small, the testing precision is high, no noise is generated in the testing process, the device is environmentally friendly and free of pollution, in addition, fragments generated after the detonator is detonated in water cannot fly into the air, no threat is caused to surrounding persons, safety and reliability are achieved, and the testing requirements under different water depth conditions can be met.

Description

technical field [0001] The invention relates to the field of electronic detonator testing, in particular to a device for testing the underwater explosion power of electronic detonators based on water shock wave signals. Background technique [0002] The importance of underwater blasting is very high. Whether it is the removal of cofferdams during dam construction, or silt discharge projects, mining projects, civil engineering, etc., underwater blasting will be required. Underwater blasting needs to strictly control the amount of explosives, and be able to detonate safely and efficiently, so as to avoid additional damage to underwater projects. [0003] As a safe, reliable, high-precision, intelligent, environment-friendly and high-performance detonating device, the electronic detonator is very suitable for the actual needs of underwater blasting projects. The Ministry of Public Security, together with the Ministry of Industry and Information Technology, held the National Ci...
