Abstract

The invention discloses an underwater high-voltage pulse discharge foaming method and device. The device includes a host computer, a boosting module, an energy storage module, a high-voltage switch, and a foaming module; A rectifier circuit, the host computer is connected to a high-voltage switch through a single-chip controller, the low-voltage power supply is connected to a high-voltage switch through a high-frequency boost module and a voltage doubler rectifier circuit in turn, and the energy storage module and the foaming module are connected to a high-voltage switch. The position of the cavitation bubble generated by the device through high-voltage pulse discharge can be adjusted by the position of the discharge electrode, and the size of the cavitation bubble can be changed by increasing or decreasing the number of series connections of the multi-voltage booster circuit, thereby forming a cavitation bubble with precise position and controllable size.

Description

technical field [0001] The invention relates to an underwater high-voltage pulse discharge foaming device and a method for using the same, belonging to the field of physics. Background technique [0002] Cavitation Cavitation is a common phenomenon in rotating machinery with liquid as the medium, which will cause damage to the propeller of the ship, and even damage solid materials such as the hull, resulting in serious consequences. With the progress and development of science, the study of cavitation cavitation is beneficial to reduce the damage of cavitation cavitation to underwater and water surface structures. Cavitation cavitation can also be used in many fields such as water treatment, medical cancer treatment, drug delivery in cells, and cleaning of fruit and vegetable and material surfaces. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, solve the problems of the prior art, and propose an underwat...
