Simulated deep water environmental explosion test device

Abstract

The invention discloses a test device for simulating deepwater environment, comprising a pot-type pressure vessel; an opening is formed in the top of the pressure container; the upper part of the opening is covered by a sealing head through a clamping-sealing cover; the surface of the outer wall is fixedly connected to an operation platform; the upper part and the bottom part of the pressure container are provided with a pressure port and a water port; the pressure container is buried inside a foundation; a pressurizing port, a port, a sealing head, an operation platform and a hoop are exposed from the ground; the bottom of the port is surrounded by a safe skirt which is projected into the pressure container; the bottom of the skirt is arranged right above the center of the pressure container; the safe skirt is provided with an axial through hole; the safe skirt is in communication with the internal of the opening and the pressure container; a plurality of damping springs are connected between the pressure container and the foundation; and the damping springs comprise a plurality of vertical damping springs arranged on the lower part of the pressure container and a plurality of transverse damping springs which are arranged on two sides of the pressure container. The invention can satisfy the explosion test condition requiring that the maximal water depth is 600m.

Description

technical field [0001] The invention relates to the technical field of simulating underwater environmental explosion tests, in particular to a test device for simulating deep water environmental explosions. Background technique [0002] Underwater explosion test research generally adopts indoor test and field test. Due to the high cost of field tests, many uncertain factors and poor repeatability, in comparison, the indoor test of simulating underwater explosion environment by filling the explosion test container with water medium is economical and easy to implement. Water depth is one of the factors affecting the underwater blasting effect and the performance of explosive equipment. According to the relationship between water depth and pressure, different water depth environments can be simulated by pressurizing the container, and further research on explosion experiments in simulated deep water environments can be carried out. [0003] Under the condition of deep-water ex...

AI Technical Summary

Problems solved by technology

Most of the existing underwater explosion test devices are small-scale test devices completely on the ground, with small pressurization, small amount of explosive charge, and no consideration of the influence of environmental pressure on the explosion bubbles. Therefore, the deep water environment explosion The simulation of the deep water environment simulated by the test is very limited
