Description

multifunctional ground wire

technical field

The utility model belongs to the technical field of temporary grounding wire devices. Specifically relates to a multifunctional grounding wire that can be used in conjunction with threaded ends, wire clamps and aluminum bars of equipment such as control boxes, distribution boxes, and meter boxes.

Background technique

At present, most of the temporary grounding wires used for power transmission and distribution lines and equipment are composed of insulating operating rods, spring-loaded hook clamps and grounding wires. The clamps are fixedly connected to the insulating operating rods, and one end of the grounding wires is connected to the clamps. For the maintenance and repair of horizontal equipment clamps and aluminum bars, it is necessary to use the grounding wire with the opening of the clamps to the left or right, and only need to touch the clamps or aluminum bars. For the maintenance and repair of the distribution box or transformer, it is necessary to use the ground wire hook with the opening of the wire clamp upward, and only need to push it to the metal conductor. Due to the different line environments, power supply maintenance and repair departments must be equipped with ground wire hooks facing different directions, and they must also carry the ground wire hooks facing different directions during work, which makes storage and carrying very inconvenient and poses a safety hazard. In addition, the control box, distribution box, and meter box are all equipped with grounding screws, and grounding is also required during maintenance and overhaul to ensure greater safety.

Contents of the invention

The purpose of this utility model is to provide a multi-functional grounding wire which is very convenient to store, carry and use, and has high safety in view of the above-mentioned deficiencies.

The technical solution of the utility model is: a multi-functional grounding wire, including an insulating operating rod, a spring-loaded hook clamp and a grounding wire, characterized in that: one end of the insulating operating rod is provided with a metal U-shaped clip, The grounding wire penetrates through the other end of the insulating operating rod and is electrically connected with the metal U-shaped clip; bolt holes and connecting bolts are provided on the front side walls of the metal U-shaped clip; Clamp bolt holes, and the thickness of the spring-loaded hook clamp matches the distance between the two side walls of the front end of the metal U-shaped clip; it also includes a metal polygonal threaded joint whose thickness matches the distance between the two sides of the front end of the metal U-shaped clip, and the metal polygonal thread Each side of the joint is provided with threaded holes with different diameters, and the center of the metal polygonal threaded joint is provided with a joint bolt hole.

The metal polygonal threaded joint described in the technical solution of the utility model is a metal regular polygonal threaded joint with 3-6 sides.

The length of the insulating operating rod described in the technical solution of the utility model is 40-50 cm.

The utility model adopts a multifunctional grounding wire composed of an insulating operating rod, a metal U-shaped clip and a connecting bolt, a spring-loaded hook wire clip, a metal polygonal threaded joint and a grounding wire, wherein the metal U-shaped clip is fixed on the insulating operation At one end of the rod, the grounding wire penetrates through the other end of the insulating operation rod and is electrically connected with the metal U-shaped clip. Bolt holes and connecting bolts are provided on the front side walls of the metal U-shaped clip. Clamp bolt holes, threaded holes with different diameters are provided on each side of the metal polygonal threaded joint, the center of the metal polygonal threaded joint is provided with joint bolt holes, spring-loaded hook clamps, metal polygonal threaded joint thickness and metal U-shaped clamp The distance between the two sides of the front end is coordinated, so when the power supply department conducts indoor maintenance and repairs, it can choose to press the metal polygonal threaded joint or spring according to the screw specifications of the control box, distribution box, and meter box or the positions of the wire clamps and aluminum bars. The tight hook clamp is installed and fixed on the metal U-shaped clamp through the connecting bolt, and the direction of the operation surface of the metal polygonal threaded joint or the spring-loaded hook clamp can be adjusted to realize the grounding operation. Due to the use of insulating operating rods with a length of 40-50 cm, multiple insulating operating rods connected with grounding wires and metal U-shaped clips, multiple metal polygonal threaded joints, and spring-loaded hook clamps can be installed. Inside a grounded box for easy storage and portability. The utility model has the characteristics of very convenient storage, carrying and use, and high safety. The utility model is mainly used for the grounding of the control box, the distribution box and the meter box during power supply maintenance and overhaul.

Detailed ways

As shown in Figure 1 to Figure 3. The multifunctional grounding wire of the utility model is made of insulating operating rod 5, metal U-shaped clamp 2 and connecting bolt, spring compression type hook clamp 9, metal polygonal thread joint 1 and grounding wire 4. The insulating operating rod 5 has a length of 40-50 cm, and the central axis is provided with a through hole. The metal U-shaped clip 2 is fixed on one end of the insulating operating rod 5, and the two front end walls of the metal U-shaped clip 2 are provided with bolt holes and connecting bolts. The grounding wire 4 is the existing grounding wire, and the wire jacket has an insulating sheath wire. The ground wire 4 is electrically connected with the metal U-shaped clip 2 after passing through the other end of the insulating operation rod 5 . The insulating operating rod 5 is provided with a handle 3 near the end of the grounding wire 4 . The metal polygonal threaded joint 1 is a metal regular hexagonal threaded joint, and its six sides are respectively provided with threaded holes 6 with different diameters, and the center of the metal polygonal threaded joint 1 is provided with a joint bolt hole 7 . The thickness of the metal polygonal threaded joint 1 matches the distance between the two side walls of the front end of the metal clevis 2, and the metal polygonal threaded joint 1 can be installed on the metal clevis 2 on site through connecting bolts, and the metal polygonal clevis can be rotated The threaded joint 1 makes its suitable threaded hole 6 end faces axially outwards, corresponding to the screws of the control box, the distribution box, and the meter box.
