Problems solved by technology

[0003] The existing underwater bubble generation device generates bubbles by ionizing water through metal wire short-circuit discharge under low-pressure and high-pressure environments. This device is switched on by manually adjusting the steering switch, and it is impossible to accurately control the initiation time and the generation of multiple bubbles.
There is also a visual experimental research device for cavitation near the wall, which uses a 55V DC power supply, and the maximum size of the generated cavitation is only 3-5mm, and the radius of the bubble is small; and the research on the interaction of double cavitation is only realized through parallel circuits, and cannot Realize the delay function
Some devices have a small voltage range and cannot achieve higher voltages, nor can they be applied to the generation and delay control of multiple bubbles
[0004] Considering the following problems in the existing technical solutions, it is impossible to accurately control the discharge voltage and discharge delay for generating multiple bubbles, and to monitor the charging voltage, and there is no automatic triggering of the high-speed camera for synchronous observation of the multi-bubble state

Description

technical field [0001] The invention relates to the technical field of underwater multi-bubble generation test, in particular to an underwater multi-bubble generation test device for precise control. Background technique [0002] In the process of underwater explosion, in addition to the formation of shock waves, the detonation of explosives also has the phenomenon of bubble pulsation, whose energy accounts for about 50% of the total energy of explosives, which is of great significance for improving the effectiveness of explosives. The underwater environment is complex and diverse, and bubbles will produce different motion characteristics when they interact with different boundary conditions. For example, if the bubble pulse occurs near the ship, it will cause fatal damage to it. If the explosion occurs near the water surface, different forms of water columns or water curtains will be formed, which can be used for air defense and anti-missile research. In reality, there ar...
