According to the technical scheme, the positions and the number of sensors are selected according to the test purpose, water is injected through a water injection and drainage system, a pressurization system is energized to give magnetic force for pressurization, waste water is discharged after the test is completed, and test data are exported. The electromagnetic effect is used for pressurization, compared with a traditional deepwater explosion testing device, the device has the advantages of being environmentally friendly, efficient, short in experimental period, simple in system design and low in device cost, and a new thought can be provided for follow-up research.

Description

technical field [0001] The invention belongs to the technical field of simulated deep-water environment explosion test. In particular, it relates to a pressure testing device for explosion shock waves in a simulated deep water free field environment. Background technique [0002] With people's exploration of nature, a large number of valuable mineral resources contained in the bottom of the water have been discovered, and blasting mining has gradually deepened from land blasting to underwater blasting. . In order to promote the development of underwater engineering blasting technology, it is very important to develop a pressure test device that simulates blasting shock waves in deep water free field environment. [0003] In order to simulate the deep water environment and explore the explosive power of the explosive in the deep water environment, it is necessary to pressurize the water medium in the explosion test container. Researchers have designed some underwater explo...

AI Technical Summary

Problems solved by technology

Connect the high-pressure gas cylinder through the high-pressure gas pipe and use the high-yield chemical reaction to generate high-pressure gas to pressurize the container for simulating the deep-water environmental explosion test. Although the pressurization process of the water medium inside the container can be completed, the former pressurization efficiency is low and the controllability is poor. ; If the large amount of toxic gas generated by the latter reaction is not handled properly and leaks, it may cause personal danger
