Description

Technical Field

[0001] The utility model relates to a grounding rod structure used for high-voltage electric wires. Background Art

[0002] During the line construction, the maintenance of the zero-speed line at the station entrance (such as the heating treatment of the down conductor clamp at the zero-speed line at the station entrance), the traditional grounding wire can only be hung at the jumper or the connecting plate, and the maintenance work at this time is not within the grounding protection range. Similarly, this problem also occurs when the jumper is connected after the zero-speed line is erected in the infrastructure project.

[0003] In the maintenance room, a grounding rod is usually used for temporary grounding. The wire clamp of a traditional grounding rod is located in the extension direction of the grounding rod body. When inspecting low-voltage wires, the staff is located below the wires. The wire clamp can be conveniently hung on the wires through the above-mentioned grounding rod. However, when inspecting high-voltage wires, the staff needs to stand at a higher place. At this height, when the staff operates the grounding rod, the grounding rod will be approximately parallel to the wire, which makes it inconvenient for the staff to operate the grounding rod to hang on the wire and tighten it, thereby increasing safety hazards. Utility Model Content

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0018] like Figure 1-4 As shown, handle 1, shaft 2, wire clamp 3, bearing 4, rotating shaft 5, first bevel gear 6, second bevel gear 7, screw 8, wire clamp seat 9, pressing plate 10, wire groove 11, threaded hole 12, slide rail 13, slide groove 14;

[0019] A grounding rod structure for a high-voltage electric wire, comprising a rod body 2, a wire clamp 3, and a rotating shaft 5. The rod body 2 is made of an insulating material and is a hollow structure. The rotating shaft 5 is installed in the rod body 2 through at least two bearings 4. A handle 1 made of an insulating material is provided at the top of the rotating shaft 5. The handle 1 extends out of the rod body 2. A first bevel gear 6 is fixedly connected to the outer wall of the rotating shaft 5. The first bevel gear 6 is meshed with a second bevel gear 7. The rotation center lines of the first bevel gear 6 and the second bevel gear 7 are perpendicular to each other. The second bevel gear 7 is fixedly installed on the outer wall of a screw rod 8.

[0020] The wire clamp 3 includes a wire clamp seat 9, a pressure plate 10, and a screw 8. The wire clamp seat 9 is a C-shaped structure. The left end face of the wire clamp seat 9 is provided with a groove that passes through the front end face and the rear end face. The inner end face of the wire clamp seat 9 located below the groove is provided with a wire groove 11. The inner end face of the wire clamp seat 9 located below the groove is opposite to the lower end face of the pressure plate 10.

[0021] The upper end face of the wire clamp seat 9 is provided with a threaded hole 12 which passes through the upper side wall of the groove. The screw rod 8 is inserted into the threaded hole 12. The end of the screw rod 8 is inserted into the center of the pressure plate 10 through the bearing 4. The pressure plate 10 is in the groove on the left side of the wire clamp seat 9. The pressure plate 10 is a rectangular structure. The surface of the pressure plate 10 is provided with a slide groove 14. The groove of the wire clamp seat 9 is provided with a slide rail 13. The pressure plate 10 is connected to the wire clamp seat 9 through the slide rail 13 and the slide groove 14.

[0022] A connecting hole is provided on the side wall of the rod body 2 , and a bearing 4 is provided at the end of the connecting hole. The inner ring of the bearing 4 is fixedly connected to the outer side wall of the screw rod 8 .

[0023] Instructions for use: The staff climbs to a suitable height and temporarily grounds themselves through the grounding rod of this patent. During this operation, the rod body of the grounding rod is approximately parallel to the wire, so that the wire is in the wire groove below the wire clamp seat groove. The staff holds the handle and rotates it, and the rotating shaft drives the first bevel gear to rotate, thereby driving the meshing second bevel gear to rotate, and then drives the screw to rotate. Since the screw is threadedly connected to the wire clamp seat, the two constitute a screw structure. Since the planar freedom of the screw is limited, and its rotational freedom is retained due to the bearing, the rotation of the screw drives the wire clamp seat to rise or fall. When the wire clamp seat rises, the gap between the inner wall below the groove and the lower end face of the pressure plate is reduced, thereby tightening the wire. When the wire clamp seat falls, the opposite is true.

[0024] During the rotation of the upper screw, since the screw is installed on the rod body through a bearing and is connected to the center of the upper end surface of the pressure plate through a bearing, the rotation of the screw will not drive the pressure plate to rotate, and the slide groove and slide rail structure between the pressure plate and the wire clamp seat groove will not interfere with the rotation of the screw.

[0025] 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.
