A Realization Method of Ultrasonic Testing of Tank Body Based on GIS

Abstract

The invention discloses an implementation method based on GIS tank ultrasonic testing, which comprises a detection head. The implementation method further comprises a connecting plate and a shell. 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; acylinder equipped with a cavity is arranged in the shell; one end of the cylinder is provided with an exit matched with the detection head; the exit communicates with the cavity; a passage is arrangedon the inner wall of the cylinder; one end of the passage communicates with the cylinder, and the other end communicates with the cavity; the detection head is located in the exit; a movable rod is arranged on the connecting plate; the movable rod penetrates through the cavity and is connected with the detection head; the movable rod can drive the detection head to move in the exit; a piston is also arranged on the movable rod; the piston is located in the cavity; the piston is sleeved on the movable rod, and the piston can move together with the movable rod. The implementation method based on GIS tank ultrasonic testing in the invention can automatically apply grease to the detection head and meanwhile ensure the stability of the detection head during detection.

Description

technical field [0001] The invention relates to a probe laminating device, in particular to a method for realizing ultrasonic testing of tanks based on GIS. 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 use...

Problems solved by technology

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
