Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0039] An arc-shaped frame 201, a magnetic clamping plate 202 is clamped inside the arc-shaped frame 201, an arc-shaped cloth belt 203 is clamped to the outer surface of the magnetic clamping plate 202, a bolt group 204 is threadedly connected inside the arc-shaped frame 201, a rotating rod 205 is rotatably connected to the outer surface of the bolt group 204, a holding surface 206 and a magnetic surface 207 are arranged on the outer surface of the rotating rod 205, a first connecting rod 208 is fixedly connected to the outer surface of the rotating rod 205, and the arc-shaped cloth belt 203 is used to fix the tooling.

[0040] The expansion mechanism 2 includes a first screw rod 209, the first screw rod 209 is rotatably connected to the rotating rod 205, a friction sleeve ring 210 is fixedly connected to the outer surface of the first screw rod 209, a sleeve 211 is threadedly connected to the outer surface of the first screw rod 209, and the friction sleeve ring 210 is used to rotate the first screw rod 209.

[0041] One end of the arc-shaped cloth belt 203 is fixedly connected to the arc-shaped frame 201, the arc-shaped cloth belt 203 is clamped to the magnetic clamping plate 202, the outer surface of the magnetic clamping plate 202 is in contact with the outer surface of the arc-shaped frame 201, the magnetic surface 207 is used to magnetically attract the display 1, the outer surface of the friction sleeve ring 210 is in contact with the outer surface of the rotating rod 205, the outer surface of the friction sleeve ring 210 is in contact with the outer surface of the sleeve 211, the first screw rod 209 and the sleeve 211 are used to expand the detection range. A plurality of through holes are arranged inside the arc-shaped cloth belt 203 and can all be clamped to the magnetic clamping plate 202. The outward movement and expansion of the sleeve 211 enable the tooling to adapt to the detection of transformers at lower positions, making the tooling conveniently adaptable to different environments.

[0042] The bending mechanism 3 includes a first groove cylinder 301, the first groove cylinder 301 is fixedly connected to the outer surface of the sleeve 211, an arc magnet 304 is fixedly connected to the outer surface of the first groove cylinder 301, a first clamping block cylinder 302 is clamped inside the first groove cylinder 301, a first motor 303 is fixedly connected to the lower surface of the first groove cylinder 301, a second connecting rod 305 is fixedly connected to the outer surface of the first clamping block cylinder 302, a second groove cylinder 306 is fixedly connected to the outer surface of the second connecting rod 305, a second clamping block cylinder 307 is clamped inside the second groove cylinder 306, a second motor 308 is fixedly connected to the upper surface of the second clamping block cylinder 307, an arc rod 309 is fixedly connected to the outer surface of the second clamping block cylinder 307, and the first motor 303 and the second motor 308 are used to adjust the angle.

[0043] The upper surface of the first clamping block cylinder 302 is flush with the lower surface of the second groove cylinder 306. The output end of the first motor 303 is fixedly connected to the first clamping block cylinder 302, and the output end of the second motor 308 is fixedly connected to the second groove cylinder 306. The arc magnet 304 is used to fix the position. The clamping connection between the first groove cylinder 301 and the first clamping block cylinder 302, and the clamping connection between the second groove cylinder 306 and the second clamping block cylinder 307 ensure that when the first motor 303 and the second motor 308 rotate, they do not directly bear the gravity of the mechanism, protecting the mechanism, the first motor 303, and the second motor 308.

[0044] The working principle of this embodiment is as follows: When using this detection tool for transformers and rectifiers, the arc-shaped cloth belt 203 is put on the operator's waist, and the tightness of the arc-shaped cloth belt 203 is adjusted by adjusting the position where the magnetic clamping plate 202 is clamped to the arc-shaped cloth belt 203. At this time, the operator is lifted by the scissor lift. At the same time, the operator holds the tool through the holding surface 206, and magnetically attracts the display 1 through the magnetic surface 207. At this time, the rotating rod 205 is rotated around the bolt group 204 through the holding surface 206, and the arc magnet 304 is magnetically attracted to the outer surface of the transformer. If there is a distance that prevents ultimate magnetic attraction, the first screw rod 209 is rotated by driving the friction sleeve ring 210, so that the sleeve 211 moves outward, thereby adjusting the position limit of the arc magnet 304 and performing magnetic attraction. After magnetic attraction, the first motor 303 rotates, causing the first clamping block cylinder 302 to rotate, driving the second connecting rod 305 to rotate, and making the arc magnet 304 on the outer surface of the second groove cylinder 306 magnetically attracted to the other side of the transformer. At this time, the transformer is detected by the detection device.

[0045] Embodiment 2: Please refer to Figures 7 - 8, on the basis of Embodiment 1, the present invention provides a technical solution: The detection mechanism 4 includes a first clamping groove 401. The first clamping groove 401 is formed inside the arc-shaped rod 309. A second screw rod 402 is rotatably connected inside the first clamping groove 401. An outer surface of the arc-shaped rod 309 is fixedly connected with a disc 404. An outer surface of the disc 404 is fixedly connected with an arc-shaped rubber pad 405 and an industrial camera 406. An outer surface of the second screw rod 402 is threadedly connected with a first slider 403. An outer surface of the first slider 403 is fixedly connected with a partial discharge detector 407. An outer surface of the first slider 403 is fixedly connected with a first spring 408. An outer surface of the first spring 408 is fixedly connected with an arc-shaped plate 409. An outer surface of the arc-shaped plate 409 is fixedly connected with a contact ultrasonic sensor 410. An outer surface of the first clamping groove 401 is fixedly connected with a telescopic plate 411. The partial discharge detector 407 and the contact ultrasonic sensor 410 are used to detect the transformer and display the detection through the display 1. At this time, by reversing the first motor 303 and the second motor 308, the detection of the other two sides of the transformer is realized.

[0046] The first slider 403 is slidably connected with the arc-shaped rod 309. An outer surface of the telescopic plate 411 is fixedly connected with an outer surface of the first slider 403. The telescopic plate 411 is flush with an outer surface of the arc-shaped rod 309. The telescopic plate 411 is used to protect the second screw rod 402. When the arc-shaped magnet 304 is magnetically attracted to the surface of the transformer, when the arc-shaped rubber pad 405 of the contact ultrasonic sensor 410 contacts the outer surface of the transformer, the contact ultrasonic sensor 410 performs detection. After reversal, the second motor 308 reverses, so that the contact ultrasonic sensor 410 can contact the surface of the transformer to realize its detection.

[0047] The working principle of this embodiment is as follows: When using this detection tool for the transformer and rectifier, during detection, the second motor 308 rotates, and the arc-shaped rubber pad 405 of the contact ultrasonic sensor 410 contacts the outer surface of the transformer. At this time, the industrial camera 406 observes the surface of the transformer and displays it through the display 1. At this time, the operator is lifted by the scissor lift, so as to observe the two sides of the surface of the transformer, and observe the other sides through the above-mentioned reversal process. By rotating the second screw rod 402, the movement of the first slider 403 is driven, so that the positions of the partial discharge detector 407 and the contact ultrasonic sensor 410 are adjusted, so that the position where the contact ultrasonic sensor 410 contacts the transformer is adjusted to an appropriate position, and the contact ultrasonic sensor 410 is pushed by the first spring 408 to contact the surface of the transformer. At the same time, the first slider 403 pushes the telescopic plate 411 to expand and contract, realizing the protection of the second screw rod 402.
