An ultrasonic probe structure and an ultrasonic electromagnetic instrument

Abstract

This application relates to the field of ultrasonic flaw detection electromagnetic equipment, and more particularly to an ultrasonic probe structure and an ultrasonic electromagnetic instrument. The ultrasonic probe structure, disposed on the surface of a gas injection device, includes a housing containing at least one gas groove body. The gas groove body has a bifurcated structure, dividing it into a main gas groove and at least two auxiliary gas grooves symmetrically arranged relative to the main gas groove. Each auxiliary gas groove is connected to a throttling gas channel, the outer end of which is connected to a pressure chamber for diffusing gas and forming a uniform gas film support. Through the step-by-step throttling combined with the external pressure chamber, suspension stability is achieved, thus solving the problem of inaccurate detection caused by the lack of effective buoyancy in existing ultrasonic probes.
