Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0022] See also Figures 1 to 2 As shown, the utility model is a lightning protection grounding wire clamp, comprising a grounding ring 1, on which an arc-starting arm 2 and a grounding rod 3 are arranged, and the grounding ring 1 is fixed on a movable ring 4, and the grounding ring 1 is installed on a wire clamp seat 8 through the movable ring 4 in a height-adjustable manner;

[0023] The wire clamp seat 8 is provided with a V-shaped clamping opening 8a and a plate frame 8b, and an adjustable clamping lower clamping block 11 is installed below the V-shaped clamping opening 8a through an adjusting screw 10, which is used to install the grounding ring 1 on the wire 14;

[0024] The adjusting screw 10 is installed on the adjusting plate 9 through threads, and the adjusting plate 9 is detachably installed on the plate frame 8b.

[0025] How it works

[0026] When using, first loosen the fastening screws, adjust the grounding ring to a suitable position and then fix it;

[0027] Insert the insulating operating rod into the operating rod lap ring, lift the wire clamp seat and install it on the wire. The installation is very convenient.

[0028] In the utility model, the grounding ring can be installed on the conductor through the insulating operating rod; the grounding ring can also be installed on the wire clamp seat in an adjustable height through the movable ring, and can be adjusted when the height cannot be adapted to the insulator.

[0029] In some embodiments, see Figure 1As shown, the grounding ring 1 is installed on the wire clamp seat 8 through a bracket 6, the bracket 6 is "L" shaped, the bottom of the bracket 6 is installed on the plate frame 8b through a fixing bolt 7, and the grounding ring 1 is slidably mounted on the bracket 6 through a moving ring 4, and the moving ring 4 is fixed or loosened by a fastening bolt 5. This arrangement facilitates the up and down adjustment of the grounding ring, and when the arc arm is not aligned with the insulator, appropriate adjustment is performed to improve the accuracy of its protection.

[0030] In some embodiments, see Figure 1 As shown, the cross section of the adjustment plate 9 is rectangular, the plate frame 8b is adapted to the adjustment plate 9, and the adjustment plate 9 is detachably installed in the plate frame 8b. This design facilitates the separate replacement of the wire clamp seat or the adjustment screw. When the adjustment screw or the wire clamp seat is used for a long time, it is easy to be corroded or weathered. This disassembly design facilitates the replacement of any damaged part, avoiding the whole part being unable to continue to be used after any part is damaged, thereby improving its reusability; at the same time, the rectangle can ensure that the clamping position of the adjustment screw is accurate during adjustment, avoiding the lower clamping block driven by the adjustment screw from being crooked.

[0031] In some embodiments, see Figure 1 As shown, the lower clamping block 11 is rotatably mounted on one end of the adjusting screw 10 , and the other end of the adjusting screw 10 is provided with an operating rod lap ring 12 .

[0032] In some embodiments, see Figure 1 As shown, one end of the adjustment plate 9 is provided with a screw hole adapted to the fixing bolt 7, and the adjustment plate 9 is fixed to the wire clamp seat 8 by the fixing bolt 7. Such a fastening bolt can simultaneously fix the bracket and the adjustment plate, fix the column adjustment plate, and prevent the adjustment plate from falling when the wire clamp seat is installed.

[0033] In some embodiments, see Figure 1 As shown, a rib plate 13 is provided below the plate frame 8b. The rib plate is used to support the plate frame to prevent the plate frame from deforming or even falling off after being clamped for too long.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
