[0002] Power fault detection devices are intelligent monitoring and diagnostic equipment applied to all aspects of power system generation, transmission, transformation, distribution and consumption.

They are key equipment to ensure the safe and stable operation of the power system and reduce the duration of power outages.

[0003] Traditional wire inspection devices are limited by fixed inspection angles and can only perform point-to-point inspections on local areas of the wire. They cannot achieve full-dimensional circumferential inspection, resulting in obvious blind spots in the circumference of the wire. This makes it impossible to conduct a comprehensive and detailed inspection of the internal wiring condition of the entire circumference of the wire, and it is very easy to miss hidden technical problems such as internal wiring damage and loose connections. Summary of the Invention

Both ends of the fixed rods are fixedly connected to fixing members, and the bottom ends of the fixing members are fixedly connected to the inner bottom end of the upper frame.

[0011] In a preferred embodiment, each of the multiple sliding rail frames is fixedly connected to an electric extension device on one side opposite to the electric extension device, and an arc-shaped frame is fixedly connected to one side opposite to the arc-shaped frame. Each compression spring is fixedly connected to one end opposite to the compression spring, and an arc-shaped compression plate is fixedly connected to one end opposite to the compression spring. Each of the two opposing sliding rail frames is fixedly connected to a telescopic rod, and a tension spring is provided on the outer side of each telescopic rod. The tension spring is fixedly connected to the side opposite to the telescopic rod on the side opposite to the arc-shaped frame, and the tension spring is located on the outer side of the telescopic rod.

[0012] In a preferred embodiment, the bottom of the mobile platform is fixedly connected to multiple base frames, each of which is movably connected to pulleys.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The power fault detection device disclosed in this invention is mainly applied to the problem that traditional wire detection devices have limited detection angles, can only detect local areas of the wire, and form a detection blind spot in the circumference of the wire. It is impossible to conduct a comprehensive inspection of the internal circuit of the entire circumference of the wire, and it is very easy to miss hidden circuit defects in the circumference of the wire.

[0020] Reference Figures 1-8 A power fault detection device includes a mobile platform 1, a telescopic pole 2 fixedly connected to the top of the mobile platform 1, a lifting frame 11 fixedly connected to the top of the telescopic pole 2, an upper frame 13 above the lifting frame 11, a wire transparent detection component 10 inside the upper frame 13, the wire transparent detection component 10 including an annular frame 1001, both sides of the annular frame 1001 fixedly connected to the inside of the upper frame 13, and an annular groove 1005 fixedly connected to the inner side of the annular frame 1001, a transparent detection device 1010 inside the annular groove 1005, and a dust absorption device 1012 below the transparent detection device 1010, the dust absorption device 1012 being located inside the annular frame 1001.

[0021] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 A servo motor 1004 is provided below the upper frame 13. The power output shaft of the servo motor 1004 is connected to the drive gear 1003 through a coupling. A rectangular groove is provided at the bottom of the upper frame 13. The drive gear 1003 is located inside the rectangular groove. A gear ring 1002 is provided above the drive gear 1003. The drive gear 1003 and the gear ring 1002 are meshed through tooth grooves. One side of the gear ring 1002 is movably connected to one side of the ring frame 1001.

[0022] In this invention, a connecting frame 1008 is fixedly connected to the side of the gear ring 1002 near the annular frame 1001, a retaining frame 1007 is fixedly connected to the top of the connecting frame 1008, and a universal ball 1006 is movably connected to the inner side of the retaining frame 1007, while the outer side of the universal ball 1006 is movably connected to the inside of the annular groove 1005.

[0023] In this invention, a semi-circular frame 1009 is fixedly connected to the bottom end of the connecting frame 1008, the top end of the transparent detection device 1010 is fixedly connected to the inner side of the top end of the semi-circular frame 1009, and a pressing spring 1011 is fixedly connected to the inner side of the bottom end of the semi-circular frame 1009. The top end of the pressing spring 1011 is fixedly connected to the bottom end of the dust absorption device 1012.

[0024] Specifically, the servo motor 1004 located below the upper frame 13 serves as the power source for the perspective detection component. When the servo motor 1004 starts and rotates, the drive gear 1003 rotates around its own axis, driving the gear ring 1002 to perform a circular motion in the horizontal direction through tooth meshing. One side of the gear ring 1002 is movably connected to one side of the ring frame 1001. The ring frame 1001 provides support and limits for the rotation of the gear ring 1002, ensuring the stability of the rotation trajectory of the gear ring 1002. The connecting frame 1008, which is fixedly connected to the side of the gear ring 1002 near the ring frame 1001, moves in sync with the circular motion of the gear ring 1002. The connecting frame 1008 rotates in one step; the retaining frame 1007 fixed at the top of the connecting frame 1008 provides a mounting carrier for the universal ball 1006. The universal ball 1006, which is movably connected to the inner side of the retaining frame 1007, is movably connected to the outer side of the annular groove 1005 fixed to the inner side of the annular frame 1001, forming a rolling support structure. The universal ball 1006 can roll freely inside the annular groove 1005, which not only supports the rotation of the connecting frame 1008 and reduces the friction during the rotation process, but also restricts the rotation trajectory of the connecting frame 1008, ensuring that the connecting frame 1008 rotates stably along the circumferential direction of the annular frame 1001 and avoiding deviation. The bottom end of the connecting frame 1008... The fixed semi-circular frame 1009 rotates synchronously with the connecting frame 1008. The semi-circular frame 1009 serves as the mounting carrier for the transparent inspection device 1010 and the dust absorption device 1012. The transparent inspection device 1010, fixed on the inner side of the top, moves in a circular motion synchronously with the semi-circular frame 1009, performing a comprehensive transparent inspection of the internal wiring of the wire along its circumference. The transparent inspection device 1010 can penetrate the insulation layer of the wire, enabling real-time detection of the connection status of the internal wires and the presence of potential defects such as breaks, loose connections, and insulation damage. Simultaneously, the pressing spring 1011 fixed on the inner side of the bottom of the semi-circular frame 1009 serves as the dust absorption device. 1012 provides elastic support. The dust absorption device 1012, fixed at the top of the pressing spring 1011, rotates synchronously with the semi-circular frame 1009. The suction port is always close to the outer surface of the wire. During rotation, the dust absorption device 1012 uses negative pressure adsorption to simultaneously clean the dust and impurities attached to the outer surface of the wire, preventing dust from affecting the detection accuracy of the transparent detection device 1010 and keeping the wire surface clean. The elasticity of the pressing spring 1011 allows the dust absorption device 1012 to adapt to the slight shaking or diameter change of the wire, ensuring that the suction port and the wire surface always maintain a suitable distance, thus improving the dust cleaning effect.

[0025] In specific application scenarios, relying on gear transmission and 1006 universal ball guide, the detection device can rotate around the wire at all angles, with no blind spots, and comprehensively investigate internal circuit defects.

[0026] It should be noted that dust removal and inspection are carried out simultaneously to adsorb dust from the surface of the wires, avoid obstruction, improve the accuracy of the transparent inspection, and eliminate interference factors in the inspection.

[0027] Reference Figure 1 , Figure 4 , Figure 7 and Figure 8 The inner side of the upper frame 13 is provided with a wire coiling and stretching assembly 14. The wire coiling and stretching assembly 14 includes two slide plates 1401, and the opposite sides of the slide plates 1401 are fixedly connected to the inner side of the upper frame 13. The opposite sides of the slide plates 1401 are movably connected to slide brackets 1402.

[0028] In this invention, two symmetrical telescopic electric rods 1406 are provided on each side of the multiple slide rails 1402. The inner sides of the slide rails 1402 located below are provided with circular holes. The inside of each circular hole is movably connected to a fixing rod 1407. Both ends of the fixing rod 1407 are fixedly connected to fixing members 1408. The bottom end of the fixing member 1408 is fixedly connected to the inner side of the bottom end of the upper frame 13.

[0029] In this invention, electric extension devices 1409 are fixedly connected to opposite sides of multiple slide rails 1402, arc-shaped frames 1403 are fixedly connected to opposite sides of electric extension devices 1409, compression springs 1411 are fixedly connected to opposite sides of arc-shaped frames 1403, and arc-shaped compression plates 1410 are fixedly connected to opposite ends of compression springs 1411. Furthermore, telescopic rods 1404 are fixedly connected to two opposite slide rails 1402, and tension springs 1405 are provided on the outer side of telescopic rods 1404. The side of tension springs 1405 opposite to telescopic rods 1404 is fixedly connected to the opposite side of arc-shaped frames 1403, and tension springs 1405 are all located on the outer side of telescopic rods 1404.

[0030] Specifically, after the wire is introduced, to address the coiled state of the wire, the electric extension device 1409 fixed on one side of the slide frame 1402 is activated. The two sets of electric extension devices 1409 synchronously generate opposing thrusts, driving the arc frame 1403 to move synchronously towards each other in the horizontal direction. The compression spring 1411 fixed on one side of the arc frame 1403 provides elastic support for the arc compression plate 1410. The arc compression plate 1410, fixed at one end opposite to the compression spring 1411, moves along with the arc frame 1403. The device moves step by step until the inner side of the arc-shaped extrusion plate 1410 is in close contact with the outer side of the wire. At this point, the telescopic electric rod 1406 extends synchronously, causing the two sets of slide rails 1402 to slide along the slide rail 1401 in opposite directions, widening the distance between the two sets of slide rails 1402. The sliding of the slide rails 1402 causes the arc-shaped frame 1403 to move outward synchronously. Under the elastic action of the extrusion spring 1411, the arc-shaped extrusion plate 1410 remains in contact with the outer side of the wire. As the distance between the slide rails 1402 increases, the arc-shaped extrusion plate 1410... The pressure plate 1410 applies a continuous tensile force to the wire, gradually straightening the coiled wire. During this process, the telescopic rod 1404, fixedly connected between the two opposing slide rails 1402, works in conjunction with the outer tension spring 1405. The telescopic rod 1404 provides guidance for the movement of the arc frame 1403, preventing the arc frame 1403 from tilting during movement. One end of the tension spring 1405 is fixed to the opposite side of the arc frame 1403, and the other end is fixed to the slide rail 1402. When 403 moves, the tension spring 1405 is stretched and generates a reverse pulling force. At the same time, the elasticity of the compression spring 1411 can adapt to different diameters of the wire, so that the arc-shaped compression plate 1410 is always in close contact with the outside of the wire, ensuring the uniformity of the straightening effect. When the wire is fully straightened, the electric extension device 1409 stops operating, the telescopic electric rod 1406 maintains the current telescopic length, the positions of the slide frame 1402 and the arc frame 1403 are fixed, and the wire remains in a straight state, preparing for subsequent testing operations.

[0031] In specific application scenarios, it can automatically straighten the coiled wires before installation, avoiding obstruction of the detection field of view and deviation of parameter detection caused by wire bending, thereby improving the accuracy of subsequent detection.

[0032] It should be noted that the arc-shaped extrusion plate 1410, together with the extrusion spring 1411, can be adapted to wires of different diameters, always closely adhering to the outside of the wire, preventing slippage during the straightening process and exhibiting strong adaptability.

[0034] A method of using a power fault detection device, comprising the following steps: Step 1: Push the mobile platform 1 and use the pulleys 4 on the base frame 3 to move the device to the position directly below the high wire to be tested. Fix the pulleys 4 to prevent displacement and to set the position for subsequent operations. Step 2: Start the drive motor 7 to release the rope 9, which will cause the telescopic pole 2 to extend and raise the upper frame 13. Then, through the hydraulic rod 12 on the lifting frame 11, the horizontal and spatial position of the upper frame 13 will be precisely adjusted. Step 3: Introduce the first end of the wire into the ring frame 1001. The moving platform 1 drives the wire through the upper frame 13 and the extended power detection device 15. Start the curling and stretching assembly, and use the arc-shaped extrusion plate 1410 to attach and straighten the curled wire. Step 4: Start the servo motor 1004, which drives the semi-arc frame 1009 to rotate around the wire via gear transmission. The dust absorption device 1012 simultaneously adsorbs dust on the surface of the wire, and the transparent inspection device 1010 inspects the internal circuit defects of the wire in a circumferential manner. Step 5: Connect the energized end of the wire to the extended power detection device 15.

Step 2: Start the drive motor (7) to release the rope (9), which will cause the telescopic pole (2) to extend and raise the upper frame (13). Then, through the hydraulic rod (12) on the lifting frame (11), the horizontal and spatial position of the upper frame (13) will be precisely adjusted. Step 3: Introduce the first end of the wire into the ring frame (1001), and the moving platform (1) drives the wire through the upper frame (13) and the extended power detection device (15). Start the coiling and stretching assembly, and use the arc extrusion plate (1410) to attach and straighten the coiled wire. Step 4: Start the servo motor (1004), which drives the semi-arc frame (1009) to rotate around the wire via gear transmission. The dust absorption device (1012) simultaneously adsorbs dust on the surface of the wire, and the transparent inspection device (1010) inspects the internal circuit defects of the wire in the circumferential direction. Step 5: Connect the energized end of the wire to the extended power detection device (15). The device detects the current, voltage and other parameters of the entire wire circuit to determine whether there are power faults such as open circuit or short circuit, and completes the detection.
