[0026] The operating principle of this type of equipment maintenance line inspection instrument is:
[0027] When it is necessary to detect the power line in the gap inside the equipment, first open the inspection instrument through the inspection instrument host 1, then extend the extension tube 2, the bending head 3 and the ultrasonic sensor 4 into the gap of the equipment, adjust the inside of the gap to make the ultrasonic sensor 4 align with the power line. When it is necessary to adjust the direction angle of the ultrasonic sensor 4, first turn the dial 6 to pull the wire 7. Since one end of the wire 7 is fixedly connected to the ultrasonic sensor 4, it can generate tension on the ultrasonic sensor 4. At this time, the joint part 301 and the joint part 302 on the bending head 3 are The influence of the connection structure of joint part 1 302 and joint part 3 303 can cause the bending head 3 to bend in one direction, and then rotate the angle of the inspection instrument host 1 to drive the ultrasonic sensor 4 to further deflect until it is suitable for the inspection angle. When the bending of the bending head 3 needs to be reset, it is only necessary to loosen the rotation of the dial wheel 6, and the torsion spring can cause the dial wheel 6 to reset and pull the wire 7. Then, under the elastic force of the support spring 305, the connection structure of joint part 1 301, joint part 2 302 and joint part 3 303 on the bending head 3 is reset.
