A probe fitting device for high-altitude gis ultrasonic testing

Abstract

The invention discloses a probe bonder for high-altitude GIS (Geographic Information System) ultrasonic testing. The probe bonder comprises a probe, a connecting plate and a shell, wherein a first elastic member is arranged between the connecting plate and the shell; one end of the first elastic member is connected with the connecting plate, and the other end is connected with the shell; a cylinder with a cavity is arranged in the shell; one end of the cylinder is provided with an outlet matching the probe; the outlet communicates with the cavity; an inner wall of the cylinder is provided witha channel; one end of the channel communicates with the cylinder, and the other end communicates with the cavity; the probe is located in the outlet; a movable rod is arranged on the connecting plate; the movable rod runs through the cavity, and is connected with the probe; the movable rod can drive the probe to move in the outlet; a piston is also arranged on the movable rod; the piston is located in the cavity; the movable rod is sleeved with the piston; and the piston can move along with the movable rod. Through adoption of the probe bonder, the probe can be automatically coated with silicone grease, thereby ensuring the stability of the probe during detection.

Description

technical field [0001] The invention relates to a probe fitting device, in particular to a probe fitting device used for high-altitude GIS ultrasonic testing. Background technique [0002] When performing GIS ultrasonic general survey, the most repeated action is the attachment of the ultrasonic probe to the surface of the GIS tank. At present, the commonly used method is that the tester holds the silicone grease box in the left hand and the probe in the right hand. During the test, apply silicone grease to the end of the ultrasonic probe, and then attach the probe to the surface of the GIS tank by hand, and keep this action for at least 15 seconds. This method is inefficient, and it is easy to cause interference and misjudgment to the ultrasonic signal due to hand shaking when maintaining the fitting action. At the same time, the hands of the tester are easily stuck with silicone grease, which is not clean enough. And for the GIS tank at a high place, the tester needs to u...

This method is inefficient, and it is easy to cause interference and misjudgment to the ultrasonic signal due to hand shaking when maintaining the fitting action. At the same time, the hands of the tester are likely to stick to silicone grease, which is not clean enough.

And for the GIS tank at a high place, the tester needs to use a ladder to test the GIS tank, but this method needs to increase the manpower to hold the ladder, and there is a risk of casualty for the tester falling from a high place, and at the same time replace the tester. Need to climb up and down the ladder and move the ladder when pointing, the test efficiency is low
