An underwater plasma sound source directional radiation device

Abstract

The invention discloses a sound source radiation device, and relates to an underwater plasma sound source directional radiation device. Deformed, difficult to replace after damage, the device itself has poor insulation and water tightness, and the energy-gathering scheme used to increase the peak sound pressure of the plasma sound source is difficult to operate, and the process is complicated. The technical points of the present invention include: rigid parabolic sound baffle, anode cone support rod, anode discharge electrode, cathode discharge electrode, cathode insulating medium support table and flange disc; the bottom of the rigid parabolic sound baffle and the center of the flange disc The flange disc is distributed with screw holes for sealing and fixing the external plasma sound source equipment; the anode conical support rod is connected to the inner side of the rigid parabolic sound baffle; the anode discharge electrode and the cathode discharge electrode, the head end The corresponding discharge center is located at the focal point of the paraboloid of the rigid parabolic acoustic baffle.

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] The underwater plasma sound source, also known as the electric spark sound source, its working principle is based on the "hydroelectric effect" theory proposed by the Soviet scientist Yutkin, that is, a high-voltage, high-current pulse discharge is carried out in a liquid medium, which produces a strong The shock wave realizes the radiation of sound energy. Plasma sound sources have the characteristics of high power, narrow pulse width and wide frequency spectrum, and are widely used in pipeline descaling, sewage treatment, sanitation and disinfection, marine geological exploration and other fields. [0003] The plasma sound source system has a large-capacity energy storage capacitor. During normal operation, it discharges into the underwater electrode channel within a microsecond time...
