Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: a novel ground wire clamp comprises a wire clamping base 1, and specifically, in the embodiment, the wire clamping base 1 is a rectangular metal block. The wire clamping base 1 is provided with a wire hook 2 with an adjustable angle through a pin shaft 3, and the wire hook 2 is provided with a hook part 2-1 with an adjustable angle. In this embodiment, the wire hook 2 is a strip-shaped metal plate as a whole, the hook portion 2-1 is a C-shaped hook portion formed by bending the upper end of the wire hook 2, and the opening of the C-shaped hook portion faces downward. The lower end of the wire hook 2 is provided with a grounding wire connecting hole. The pin shaft 3 is an adjusting bolt capable of locking the angle of the wire hook 2, and the adjusting bolt is connected with the wire clamping base 1 through threads. Namely, a through hole is arranged at the lower end of the wire hook 2, a threaded hole is processed at the side part of the wire clamping base 1, and an adjusting bolt serving as a pin shaft 3 penetrates through the through hole to be combined with the threaded hole at the side part of the wire clamping base 1. And locking the adjusting bolt to fix the angle of the wire hook 2. The adjusting bolt is loosened, the angle of the wire hook 2 can be adjusted, and the adjusting range is the rotating range around the axis of the adjusting bolt.

The thread clamping base 1 is provided with a locking screw rod 4 which can be close to the hook part 2-1 at the end part through threads. Specifically, the locking screw 4 is installed in the middle of the wire clamping base 1, and the upper end of the locking screw is opposite to the hooking part 2-1 of the wire hook 2 when the wire hook 2 is in the middle position. The locking screw rod 4 is rotated, and the upper end of the locking screw rod 4 can be close to or far away from the hook part 2-1 under the action of the threads.

The end part of the locking screw rod 4 is provided with a semi-annular splint 5, the wire hook 2 is positioned at the side of the semi-annular splint 5, a wire clamping groove is formed between the hook part 2 and the semi-annular splint 5, and the outer arc surface of the semi-annular splint 5 is opposite to the wire hook 2. Under the drive of the locking screw rod 4, the outer arc surface of the semi-annular clamping plate 5 is close to or far away from the hook part 2-1, and the wire clamping groove is reduced or enlarged, so that the clamping action is realized.

Semi-annular splint 5 is connected with locking screw 4 in order can be around 4 axis pivoted modes of locking screw, and is concrete, and semi-annular splint 5's intrados is equipped with T shape hole, and the round hole is processed earlier at semi-annular splint 5's intrados in T shape hole, later utilizes the coaxial aperture of screw fixed band and round hole to form at the round hole opening. The upper end of the locking screw rod 4 is provided with a T-shaped joint matched with the T-shaped hole. In the process of rotation of the locking screw 4, under the stopping action of the wire hook 2, the semi-annular clamping plate 5 only moves linearly close to or far away from the wire hook 2, and cannot rotate along with the locking screw 4.

In the embodiment, the outer arc surface of the semi-annular clamping plate 5 opposite to the wire hook 2 is provided with a clamping groove 5-1 extending along the arc surface. The clamping is more stable.

The wire hook 2 in the clamp is connected with a grounding wire, and the wire hook 2 is adjusted to a proper angle before operation so as to be perpendicular to a hung wire when the wire hook is operated. The grounding rod 6 is fixed with the locking screw rod 4, the grounding rod 6 is used as an operating rod for operating the clamp, and after the wire hook 2 is hooked on a wire, the grounding rod 6 is rotated to control the locking screw rod 4 to rotate so as to control the clamp to clamp. The grounding rod 6 and the locking screw rod 4 can be connected through threads.

The maintainer can adjust the angle beta between the wire hook 2 and the ground rod 6 by adjusting the adjusting bolt, so that the wire hook 2 is perpendicular to the hung wire 7, and the wire hook 2 is easily hung on the wire 7. Delta ABC formed by the center lines of the wire 7, the grounding rod 6 and the wire hook 2, wherein the relationship of three included angles is as follows:

α+β+θ＝180°

wherein: alpha is an included angle between the grounding rod 6 and the lead 7; beta is an included angle between the wire hook 2 and the ground rod 6; theta is the included angle between the wire 7 and the wire hook 2. When the wire hook 2 is vertical to the hung wire 7, the wire hook 2 is most easily hung on the wire 7, so that the included angle between the wire 7 and the wire hook 2 is taken

θ＝90°，

Then α + β =90 °

β＝90°-α

∵α∈[0°，180°]

∴β∈[-90，90°]

It can be seen that the adjustment range of β is-90 ° to 90 ° (β =0 ° when the wire hook 2 is in the same line with the ground rod 6). The adjustment range of beta is so large that the maintainer can easily hang the grounding wire on the wire outside the porcelain insulator string of the strain tower by using the adjustable multi-angle grounding wire clamp on the strain tower, and the grounding is reliable.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
