Underwater plasma sound source directed radiation device

Abstract

The invention discloses an sound source radiation device and relates to an underwater plasma sound source directed radiation device, for improving the problems existing in the conventional device thatthe end face of a discharge electrode tip is not ablation resistant, non-uniform in ablation, easy to deform and difficult to replace after damage, the device is poor in own insulating property and water tightness, an energy gathering scheme for improving a peak sound pressure of a plasma sound source is high in operating difficulty and complicated in process, and the like. According to technicalkey points, the underwater plasma sound source directed radiation device disclosed by the invention comprises a rigid parabolic sound barrier, a conical anode supporting rod, an anode discharge electrode, a cathode discharge electrode, a cathode insulating medium supporting table and a flange disc, wherein the bottom of the rigid parabolic sound barrier is connected with the center of the flangedisc; screw holes in sealed fixed connection with an external plasma sound source device are distributed in the flange disc; the conical anode supporting rod is connected with the inner side of the rigid parabolic sound barrier; and corresponding discharge centers at head ends of the anode discharge electrode and the cathode discharge electrode are positioned on the focus of a paraboloid of the rigid parabolic sound barrier.

Description

technical field [0001] The invention relates to a sound source radiation device, in particular to an underwater plasma sound source directional radiation device. Background technique [0002] Underwater plasma sound source, also known as electric spark sound source, its working principle is based on the theory of "hydroelectric effect" proposed by the former Soviet scientist Yutekin, that is, high voltage and high current pulse discharge in liquid medium, resulting in The strong shock wave realizes the radiation of sound energy. The plasma sound source has the characteristics of high power, narrow pulse width, and wide frequency spectrum, and is widely used in the fields of pipeline descaling, sewage treatment, sanitation and disinfection, and marine geological exploration. [0003] The plasma sound source system has a large-capacity energy storage capacitor. During normal operation, it discharges into the underwater electrode channel within microseconds to form a high-temp...
