The device applies short-circuit discharge of metal wires under high-voltage underwater environment to rapidly ionize and vaporize water to generate large bubbles, which can more realistically simulate the working conditions of actual explosions. It provides good help to the disturbance and destruction of the ship; the device is easy to operate, safe and reliable, with strong repeatability, good experimental effect and low cost.

Description

technical field [0001] The invention relates to an underwater disturbance test device, in particular to an underwater high-voltage discharge bubble generating device. Background technique [0002] Bubbles produced by underwater explosions or underwater disturbances have an important impact on the safety of the hull. The bubbles produced by underwater explosions and the resulting powerful jets may cause damage to the hull. The violent destructive effect of the bubbles produced by the underwater explosion and the resulting jet is only cut off in the middle. Therefore, it is of great significance to study the bubbles produced by underwater explosions or underwater disturbances and their impact on the hull. [0003] Due to the destructiveness and high cost of underwater explosion experiments, and the strict control of explosives, it is unrealistic for ordinary researchers to conduct frequent full-scale, realistic explosive tests. Therefore, researchers at home and abroad are c...

AI Technical Summary

Problems solved by technology

[0007] (1) The device cannot achieve a stable linear DC output from 0 to (ultra) high voltage, the voltage is unstable, the experiment operation is troublesome, there is no capacitor discharge function after the experiment, and the safety protection measures are not enough;

[0008] (2) Capacitors are connected by multiple sets of capacitors to obtain capacitor banks, which will cause instability and many accidental events, and the experiment is unstable;

[0009] (3) The high-voltage switch cannot be operated at a short distance, and there are safety hazards (switch breakdown discharge) during operation, and there is no safety alarm system, which brings great psychological pressure to the equipment operator

[0010] Document 2 uses an electric spark ignition method as a bubble generating device, but this device cannot ionize water molecules to generate a large amount of gas like high-voltage electricity, so it cannot generate ideal large bubbles and cannot be used for simulation (ship or ship model) the real scene of underwater explosion bubbles
