DETAILED DESCRIPTION
[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0020] Example 1
[0021] A grounding wire device, such as Figure 1-Figure 5 As shown, it includes a hook 1, a first mounting ring 2, a latch 3, a first spring 4, a ball joint 6, an insertion rod 7 and a mounting shell 8. The first mounting ring 2 is arranged on the right side of the hook 1, a notch is opened on the left side of the hook 1, a latch 3 is movably passed through the left side of the hook 1, the latch 3 passes through the notch, a first spring 4 is sleeved on the outside of the latch 3, the upper end of the first spring 4 is connected to the hook 1, and the lower end of the first spring 4 is connected to the latch 3, a ball joint 6 is rotatably arranged on the bottom of the hook 1, the ball joint 6 is connected to the insertion rod 7, a mounting shell 8 is movably sleeved on the outside of the insertion rod 7, and the ball joint 6 is vertical to the ground with the insertion rod 7 in the absence of external force.
[0022] The high-voltage line power maintenance worker inserts a ground wire into the ground before inspecting the high-voltage line. Then, the other end of the ground wire is fixed in the first mounting ring 2. The worker takes the device to the equipment to be inspected and pulls down the pin 3. The pin 3 moves downward to squeeze the ground wire of the equipment into the hook 1 through the exposed gap. The pin 3 is released and reset to seal the gap, thereby adding a ground wire.
[0023] Example 2
[0024] On the basis of Example 1, Figure 1 As shown, it also includes a magnet block 5, a guide frame 9, a sliding rod 10, an iron ring 11, a second mounting ring 12, a second spring 13, a telescopic rod 14 and an insulating sleeve 15. The guide frame 9 is installed on the right side of the mounting shell 8, and the sliding rod 10 is slidably penetrated in the guide frame 9. The iron ring 11 is installed on the top of the sliding rod 10, and the second spring 13 is sleeved on the outside of the sliding rod 10. The magnet block 5 is installed at the bottom of the first spring 4. The iron ring 11 and the magnet block 5 are magnetically attracted to each other. The second mounting ring 12 is installed at the bottom of the sliding rod 10, and the telescopic rod 14 is installed at the bottom of the mounting shell 8. The telescopic end of the telescopic rod 14 is connected to the bottom of the mounting shell 8, and the insulating sleeve 15 is sleeved on the outside of the telescopic rod 14.
[0025] In order to prevent the ground wire of the equipment from being electrified and shocking the staff, a pull rope is set in the second mounting ring 12. When the equipment ground wire needs to be inserted into the hook 1, the pull rope is pulled downward, and the pull rope drives the sliding rod 10 to move downward. The sliding rod 10 moves downward with the iron ring 11. The iron ring 11 magnetically attracts the magnet block 5, and the magnet block 5 moves downward with the pin 3. The gap opens, and the equipment ground wire can be squeezed into the hook 1 through the gap, which facilitates pulling the pin 3. If you want to stay away from the equipment during work, you can extend the telescopic rod 14 to achieve long-distance control.
