[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a power grid fault diagnosis device, including a fixed base 1, a movable base 2 slidably installed on the inner wall of the top of the fixed base 1, a limit bolt 3 rotatably installed on the top of the fixed base 1, an opening 4 on the side of the fixed base 1, a movable plate 5 movably installed at the opening 4, a drive roller 6 rotatably installed inside the fixed base 1, a transmission base 7 fixed on the side of the fixed base 1, a drive motor 8 fixedly installed on the transmission base 7, the drive motor 8 being connected to the drive roller 6 through an output shaft, a pulley rotatably installed inside the transmission base 7, the pulley being mounted on the output shaft, a transmission belt rotatably installed between the pulleys, the drive motor 8 driving the pulleys to rotate through the output shaft, the pulleys driving the drive rollers 6 to rotate synchronously through the transmission belt, the synchronous rotation of the drive rollers 6 causing the fixed base 1 to be suspended on the cable for mobile diagnosis.
[0026] In this embodiment, the inner wall of the movable plate 5 has a groove 18, and a tension mechanism 19 is fixed inside the groove 18. One end of the tension mechanism 19 is fixed with a protrusion 20, which is fixed to the inner wall of the fixed base 1. A slider 14 is welded to the top of the movable base 2. A sliding groove 21 is opened on the inner wall of the fixed base 1. The slider 14 is slidably installed inside the sliding groove 21 through the support mechanism 15. A limit hole 13 is opened on the top of the movable base 2. One end of the limit bolt 3 is rotatably installed inside the limit hole 13. The tension mechanism 19, the support mechanism 15, and the reset mechanism 17 are all springs. Under the support of the reset mechanism 17, the limit roller 10 pushes the cable to squeeze and limit at the active roller 6 through the rebound force of the reset mechanism 17 to increase friction, which facilitates the movement of the fixed base 1 as a whole in the later stage.
[0027] In this embodiment, a fixed tube 12 is fixed to the bottom of the movable seat 2. A fixed column 11 is movably installed inside the fixed tube 12. A fixed frame 9 is welded to one end of the fixed column 11. A limiting roller 10 is rotatably installed inside the fixed frame 9. A limiting block 16 is fixed to the side of the fixed column 11. The fixed column 11 is installed inside the fixed tube 12 through a reset mechanism 17. A support frame 22 is fixed inside the fixed seat 1. A ring seat 23 is fixed to one end of the support frame 22. The ring seat 23 is a high-voltage clamp ammeter, model ETCR9000. A slot is opened on the ring seat 23. The cable is movably installed inside the ring seat 23 through the slot, which facilitates the rapid positioning and installation of the cable later. After the cable is installed, the active roller 6 and the limiting roller 10 cooperate to make the cable move stably inside the ring seat 23.
[0028] Working principle: In use, the movable plate 5 is moved upward, opening the opening 4. The cable enters the fixed base 1 through the opening 4 and is installed between the drive roller 6 and the limit roller 10. When the cable diameter is small, the movable base 2 pushes the limit roller 10 inward. After the limit roller 10 moves inward, it loses the support of the drive roller 6. The reset mechanism 17 pushes the fixed column 11 downward. After the fixed column 11 moves downward, the limit roller 10 on the fixed frame 9 squeezes the cable. Under the squeeze, the cable fully contacts the surface of the drive roller 6. The drive motor 8 is started to drive the drive roller 6 to rotate. As the drive roller 6 rotates, the fixed base 1 moves on the cable. When the fixed base 1 moves, the cable moves inside the ring seat 23, which is a high-voltage clamp ammeter. Its model is ETCR9000. After the cable moves inside the ring seat 23, the internal current is detected. The current data is displayed through an external device. When the cable breaks or is open-circuited, it is displayed through an external display device. The external display device connects to the device via Bluetooth. The external power cord is connected to the fixed seat 1 to provide the required power. The power cord is connected to the power supply equipment on the ground and moves through the required power of the drive motor 8. When the diameter of the cable is large, after the cable is installed on the active roller 6, the movable seat 2 drives the limit roller 10 to move to the top of the active roller 6. The limit roller 10 contacts the active roller 6 during movement and rotates to the top of the active roller 6 with the active roller 6 as the fulcrum. After the limit roller 10 is adjusted, the limit bolt 3 is rotated and installed inside the limit hole 13 to limit the movable seat 2.
