Ultrasonic non-contact leakage discharge detector

The invention discloses an ultrasonic non-contact type leakage discharge detector comprising a conical ultrasonic energy concentrator arranged at the front end of a shielding case. A through hole is formed in the center of a base; a concave worm is formed in the position, right opposite to the through hole, of the shielding case, and an ultrasonic sensor is embedded in the concave worm. A laser positioning emitter and a display screen are arranged on the shielding casing in a front-and-back manner. A lithium battery and a control mechanism are arranged in the shielding case, the output terminal of the lithium battery is connected with a power input terminal of the control mechanism, the output terminal of the ultrasonic sensor is connected with the input terminal of the control mechanism,and the output terminal of the control mechanism is connected with the input terminals of the ultrasonic energy concentrator, the laser positioning transmitter and the display screen. A handle is arranged below the shielding
