Electro-acoustic transformation electrode

Abstract

An electro-acoustic transformation electrode comprises a high-voltage electrode (1), an inner insulating cylinder (2), an outer metal cylinder (3), a ground terminal (4), a second outer cylinder (5) and a metal cap (6), wherein the upper portion of the inner insulating cylinder (2) is sleeved with the metal cap (6), the lower portion of the outer metal cylinder (3) is sleeved with the second outer cylinder (5), the inner insulating cylinder (2) is installed in the outer metal cylinder (3), the high-voltage electrode (1) is formed by bundling of multiple single-core insulated cables in the same length, an insulating layer at one end of each insulated cable is stripped off, exposed center conductors are welded together to serve as the leading-out end of the high-voltage electrode (1) to be connected with the high-voltage output end of an external power supply, the other end of the high-voltage electrode (1) is placed in liquid with certain electrical conductivity, the enclosed space defined by the outer metal cylinder (3), the second outer cylinder (5) and the inner insulating cylinder (2) is filled with the liquid, and the high-voltage electrode (1) is inserted into the inner insulating cylinder (2) to be sealed and fixed.

Description

technical field [0001] The invention relates to a pulse discharge electrode, in particular to an electroacoustic conversion electrode which converts discharge energy in water into pulse sound energy or seismic wave energy. Background technique [0002] Pulse discharge technology in water has been widely used in the fields of industry, science and medicine, and the electric spark source is one of its potential applications in the field of seismic exploration. The spark source is a huge shock wave formed in water by high-current discharge. The shock wave propagates through the liquid and the surface layer, and finally is received by the geophone to obtain geological and topographical features. Traditional EDM sources must rely on large water bodies. For example, marine EDM sources discharge in vast seawater, while land EDM sources also need to dig wells and inject water in the exploration site, and then place electrodes into the well water for discharge. Therefore, for seismi...
