[0002] High-voltage transmission lines and substations form the backbone of the power system and are its most important components. The safe, reliable, and stable operation of high-voltage transmission lines directly impacts the stable development of the national economy. Power cables, as conductors for power transmission, bear extremely important power transmission responsibilities and have been in service for over a century since the first cable was laid. In actual line operation, factors such as construction defects, aging, manufacturing defects, and installation defects lead to a very high probability of cable failure. Therefore, it is essential to inspect high-voltage transmission equipment.

[0003] In the Chinese patent with publication number CN218382469U entitled "A Novel High-Voltage Cable Fault Diagnosis Device", an electric telescopic rod, a fixed plate, a camera device and a display are used in conjunction to facilitate fault detection of high-voltage cables and check for damage. At the same time, the height of the camera device can be easily adjusted to facilitate fault detection of high-voltage cables at different heights, thus improving its practicality.

[0004] However, this device still has shortcomings. Cable maintenance workers need to climb ladders to higher positions to inspect and maintain the cables, but there are no good safety measures at the ladders. In addition, workers need to carry maintenance tools with them when working at heights, which not only increases the difficulty of operation for maintenance workers, but also increases the risk of accidents. In order to solve the above problems, the inventor proposed a high-voltage cable fault detection device based on X-ray imaging technology. Utility Model Content

[0005] To address the lack of adequate safety measures at the ladder and the increased operational difficulty for maintenance personnel who need to carry maintenance tools while working at heights, this utility model aims to provide a high-voltage cable fault detection device based on X-ray imaging technology.

[0007] Preferably, a guide shaft is symmetrically fixedly connected to the top of the top plate and near one side, and the placement plate is slidably connected to the guide shaft. A telescopic shaft is symmetrically fixedly connected to the top of the top plate and near the guide shaft, and the output end of the telescopic shaft is fixedly connected to the placement plate.

[0008] Preferably, a motor is fixedly connected to the bottom end of the placement plate, and the output end of the motor passes through the placement plate and is fixedly connected to the rotating seat.

[0009] Preferably, an electric cylinder is fixedly connected to the top of the top plate and near the center of the other side, the output end of the electric cylinder passes through the top plate and is fixedly connected to the workbench, and a tool rack is fixedly connected inside the tool box and near one side.

[0010] Preferably, a limiting plate is fixedly connected to the top of the guide shaft, and a push handle is fixedly connected to the center of the side end of the equipment base.

The electrical components in this application are electrically connected to their compatible power supply through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection methods are known in the art.

[0023] By adopting the above technical solution, two guide shafts 3 are set up to slide and lift the placement plate 31 and adjust the height of the X-ray flaw detector body 34.

[0024] A telescopic shaft 35 is symmetrically fixedly connected to the top of the top plate 12 and near the guide shaft 3. The output end of the telescopic shaft 35 is fixedly connected to the placement plate 31.

[0025] By adopting the above technical solution, the working telescopic shaft 35 is activated, causing the fixedly connected placement plate 31 to rise under the action of the guide shaft 3.

[0026] A motor 36 is fixedly connected to the bottom of the placement plate 31, and the output end of the motor 36 passes through the placement plate 31 and is fixedly connected to the rotating seat 32.

[0027] By adopting the above technical solution, the motor 36 is operated, thereby causing the fixedly connected rotating seat 32 to rotate.

[0028] An electric cylinder 25 is fixedly connected to the top of the top plate 12 and near the center of the other side. The output end of the electric cylinder 25 passes through the top plate 12 and is fixedly connected to the worktable 2.

[0037] When a faulty cable is detected and needs repair, the worker can first place the repair tools on the tool box 23 and tool rack 24 on the side of the workbench 2. Then, the worker steps onto the workbench 2 and starts the electric cylinder 25, which causes the fixedly connected workbench 2 to rise under the action of the lifting column 11.
