Abstract

The invention provides a large power underwater plasma strong sound source discharge electrode head, consisting of a detachable discharge contact and a discharge electrode pole; the detachable discharge contact is installed on one end of the discharge electrode pole; and the detachable discharge contact is in assembly connection with one end of the discharge electrode pole through conical surface meshing and screw locking. The large power underwater plasma strong sound source discharge electrode head can realize small contact resistance and a good watertight function, which can guarantee high discharge efficiency, discharge stability, avoids the problem of sintering under big power and big current, and provides convenience to updating maintenance of the discharge contact. The detachable discharge contact adopts a high strength ablation-resistant alloy inner core and an external conductive layer which is good in conductivity and shock resistance and forms an integrated body through sintering or fusion casting in a composite structure mode, so that the contact obtains good discharging characteristics and ablation resistance. The large power plasma underwater strong sound source discharge electrode head can reliably decompose the big shock borne by the discharge contact, improves the conductivity performance and heat conduction performance, effectively reduces the heat accumulation of the discharge contact, and prolongs the service life of the electrode head.

Description

technical field [0001] The invention relates to a discharge electrode head, in particular to a high-strength, impact-resistant and ablation-resistant detachable discharge electrode head for high-power underwater plasma strong sound sources. Background technique [0002] When the underwater plasma strong sound source is working, a high voltage (above 10kV) is used to act instantaneously between the two underwater electrodes to generate an arc or corona discharge behavior, and a plasma channel is formed between the two electrodes, thereby generating a huge energy impact pressure wave. Therefore, the discharge electrode is the core component that converts the electrical energy of the system into mechanical energy in the strong underwater plasma sound source, directly determines the electroacoustic conversion efficiency, pulse characteristics and working life of the system, and is also a key consumable component that needs to be replaced frequently. When the head of the dischar...
