[0002] In the live working practice of distribution network, live disconnecting and connecting lead is a routine task, but the detached lead is often left hanging in the air in the past, which hides a security risk that cannot be ignored. First of all, it is easy to cause inter-phase short circuit problem, especially under the action of wind, the hanging lead is easy to contact with the adjacent phase lead, directly leading to short circuit accident. Secondly, the lead that has been connected to the line may also induce electricity to the phase that has not been connected, which not only interferes with the subsequent work of the workers, but also may constitute a security risk of touching the lead. Moreover, for the workers who use the insulated glove working method to disconnect and connect the lead, they need to pay attention to avoid the lead hanging in the air at all times, which increases the difficulty and complexity of the work.
[0003] In the existing method, the operator locks the lead line close to one end of the line with an insulating lock rod, and the ground electrician uses an insulating rope to pass an insulating binding line cutter and a three-toothed scraper to the pole, and fixes the lowered lead line on the cross arm or electric pole to prevent it from swinging or affecting the work. The operation of winding the lead line in the air does not change, and there is a greater security risk. The lead line is not suitable to be wound on the electric pole if it is too long or too short.

[0029] Example 1
[0030] As shown in the figure, an overhead line lead wire safety fixing device includes a first insulating rod, a second insulating rod, and a wire clamping assembly; the first insulating rod and the second insulating rod are arranged perpendicular to each other, and one end of the first insulating rod is connected to the middle of the second insulating rod; the wire clamping assembly includes a first wire clamping assembly, a second wire clamping assembly, and a third wire clamping assembly; the first wire clamping assembly is installed at one end of the second insulating rod, and the third wire clamping assembly is installed at the other end; the second wire clamping assembly is installed at the other end of the first insulating rod.
[0031] The working principle of this embodiment:
[0032] Each lead wire safety fixing device consists of a first insulating rod and a second insulating rod. The first insulating rod has wire clamping structures at both ends, one of which can rotate 360° around the insulating rod (to rotate, loosen the screw on the sleeve and rotate the sleeve until the wire clamping structure is in the desired position). The second insulating rod has a sleeve at one end and a wire clamping structure at the other. In use, the wire clamping structure on the second insulating rod is installed on the main line, so that the first insulating rod is vertically installed below the line conductor. Simultaneously, the position of the second insulating rod on the first insulating rod and the wire clamping structure on the second insulating rod are adjusted so that the clamping structure can hold the lead wire in the appropriate position. This provides a device specifically designed for the safe fixing of overhead line leads, allowing for flexible adjustment of the wire clamping position to adapt to different line layouts. It effectively fixes the lead wire, reduces safety hazards, and is relatively easy to operate, reducing labor intensity.
[0033] Example 2
[0034] The difference between this embodiment and Embodiment 1 is that the wire clamping assembly includes a wire pressing block, a pressing tongue, a connecting rod, and a sleeve; the left end of the wire pressing block is provided with a pressing tongue, and the bottom surface is provided with a connecting rod; one end of the first insulating rod where the wire clamping assembly is installed and both ends of the second insulating rod are provided with sleeves; one end of the connecting rod is connected to the bottom surface of the wire pressing block, and the other end is connected to the sleeve.
[0035] By loosening the fixing screw, the pressure tongue is pressed against the inside of the clamping block. After inserting the lead wire, the pressure tongue is released, and the screw is tightened to clamp the lead wire. Sleeves are installed on the first and second insulating rods to connect with the connecting rod to the wire clamping assembly. Loosening the fixing screw 2, the pressure tongue 11 is pressed against the inside of the clamping block 12. The lead wire is placed in the receiving hole formed by the pressure tongue 11 and the clamping block 12. The pressure tongue 11 is released and springs back to its original position. The screw 2 is then tightened to clamp the lead wire.
[0036] The working principle of this embodiment is the same as that of Embodiment 1.
[0037] Example 3
[0038] The difference between this embodiment and Embodiment 2 is that it also includes a fixing screw; the lower end of the pressure block has a threaded hole, and the lower end of the pressure tongue has a through hole; the fixing screw passes through the through hole at the lower end of the pressure tongue and the threaded hole at the lower end of the pressure block, fixing the pressure tongue to the pressure block. By adding a fixing screw to fix the pressure tongue to the pressure block, the stability of the pressure tongue when clamping the lead wire is ensured, further enhancing the robustness of the clamping structure, preventing the lead wire from slipping out, and improving the safety of the device.
[0039] The working principle of this embodiment is the same as that of Embodiment 1.
[0040] Example 4
[0041] The difference between this embodiment and embodiment 3 is that it also includes a connecting screw; a through hole is formed in the middle of the connecting rod and the sleeve; the connecting screw passes through the through hole in the middle of the connecting rod and the sleeve, connecting the connecting rod and the sleeve together. Connecting the connecting rod and the sleeve together with the connecting screw makes the connection between the wire clamp assembly and the insulating rod more secure, ensuring that the wire clamp assembly will not separate from the insulating rod during use, thus improving the overall reliability of the device.
[0042] The working principle of this embodiment is the same as that of Embodiment 1.
[0043] Example 5
[0044] The difference between this embodiment and embodiment 4 is that it also includes a sliding sleeve; a sliding sleeve is installed at the other end of the first insulating rod; the sliding sleeve is fitted onto the body of the second insulating rod. Installing a sliding sleeve on the first insulating rod and fitting it onto the body of the second insulating rod allows for position adjustment, increasing the flexibility of the device. The position of the second insulating rod can be adjusted according to actual needs, better adapting to different working scenarios.
[0045] The working principle of this embodiment is the same as that of Embodiment 1.
[0046] Example 6
[0047] The difference between this embodiment and embodiment 5 is that a fixing threaded hole is provided in the middle of the sliding sleeve. By providing a fixing threaded hole in the middle of the sliding sleeve, the sliding sleeve can be fixed to a specific position on the second insulating rod using a fixing component. This ensures that the device will not move due to external force after the position is adjusted, thus improving the stability of the fixed lead.
[0048] The working principle of this embodiment is the same as that of Embodiment 1.
[0049] Example 7
[0050] The difference between this embodiment and embodiment 6 is that the upper ends of the pressure tongue and the wire clamping block are respectively provided with arc-shaped grooves. The arc-shaped grooves on the upper ends of the pressure tongue and the wire clamping block are used to better conform to the shape of the lead wire and clamp it. The arc-shaped grooves increase the contact area with the lead wire, reduce damage to the lead wire, and improve the clamping firmness.
[0051] The working principle of this embodiment is the same as that of Embodiment 1.
[0052] Example 8
[0053] The difference between this embodiment and Embodiment 7 is that the lengths of the first and second insulating rods are 0.5m. Setting the lengths of the first and second insulating rods to 0.5m facilitates operation and portability; the suitable lengths make the device easier to carry and operate, improving work efficiency. Simultaneously, the entire device can quickly and conveniently complete the work of disconnecting and connecting live leads, eliminating safety hazards such as induced current and phase-to-phase short circuits, and reducing labor intensity.
[0054] The working principle of this embodiment is the same as that of Embodiment 1.
[0055] In summary, the present invention has the following beneficial effects:
[0056] 1. This invention utilizes a wire clamping assembly, a first insulating rod, and a second insulating rod suspended in the air. The insulating rod, 0.5m in length, is vertically installed below the conductor. Plastic wire clamping structures are installed at both ends, clamping the main wire at one end and the lead wire at the other, thus securing the lead wire. The clamping points can be freely moved and fixed on the insulating rod, adjusting the distance between the wires for clamp installation. This allows for quick and convenient connection and disconnection of live lead wires, effectively solving operational difficulties, eliminating safety hazards such as induced current and phase-to-phase short circuits, and reducing labor intensity.
[0057] 2. The 0.5m long insulating rod is reasonably designed, making it easy to operate and carry. Meanwhile, the wire clamping assembly can move and be fixed freely on the insulating rod, allowing for quick adjustment of the wire spacing for clamp installation. This makes live wire disconnection and connection work more convenient and efficient, greatly reducing labor intensity.
