Miniature exploder for testing deep sea pressure resistance of explosive

Abstract

The invention relates to a miniature exploder for testing the deep sea pressure resistance of an explosive, which comprises the following components: an explosion system, a pressurization system and a pressure container, wherein the explosion system comprises an initiator, an initiation wire, a miniature threaded rod, a detonator leg wire, a detonator and the explosive; the pressurization system comprises an explosion system inflation hose, a joint, an explosion system throttle valve, a three-way valve, a pressure gage, a gas generator inflation hose, a gas generator throttle valve and a gas generating device; the pressure container comprises an upper plug, a pressure container shell and a lower plug; the detonator and the explosive are arranged in the water in the pressure container shell which is sealed by the upper and lower plugs and are connected with the initiator through the detonator leg wire and the initiation wire; and the gas which is generated by the gas generating device is inflated to the water surface through the gas generator inflation hose, the three-way valve and the explosion system inflation hose, thus the pressure of the explosive is equal to the pressure of the simulated water depth. The exploder provided by the invention provides the basis of explosive loading when the explosive is exploded in the actual underwater environment according to the damage of the explosive to the simulated environment.

Description

technical field [0001] The patent of the present invention relates to an explosive device for testing the performance of explosives, in particular to a miniature explosive device for testing the anti-deep water pressure performance of explosives. Background technique [0002] Underwater engineering blasting technology has been widely used in the dredging of ports and waterways to blast reefs, the demolition of water retaining cofferdams or rock ridges, the blasting of underwater rock plugs in reservoirs, the blasting reinforcement of silt and saturated sand foundations, etc. The design of underwater blasting requires data such as water depth, current velocity, tidal difference, wave height, wind speed, etc., more accurate underwater topographic maps and detailed hydrogeological data. In addition, the water and pressure resistance of blasting equipment, especially in deep water blasting, must be paid attention to. According to relevant literature, for ordinary water-resistan...
