DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As shown in FIG. 1 and FIG. 2, the present invention discloses a grounding segment for a segmented grounding electric device, including two groups of segment single bodies 1 that are disposed in a matched manner. A locking apparatus 6 playing a role in connection is mounted between the two groups of segment single bodies 1. The locking apparatus 6 includes a through hole 5 penetrating two ends of the segment single body 1. The two groups of segment single bodies 1 are fixedly connected by threading a locking bolt through the through hole 5. A curved concave surface 2 is formed in the outer side surface of each segment single body 1. A chute 3 is formed in the curved concave surface 2. The interior of the chute 3 is in sliding connection with an elastic member 31. The elastic member 31 is a compression spring. As shown in FIG. 3 and FIG. 4, two ends of the elastic member 31 are respectively connected to sliders 32. Each slider 32 is in sliding connection with the interior of the chute 3. The outer side surface of each slider 32 is hinged to a curved fixing member 4 that matches a grounding conductor.

[0031] As shown in FIG. 2 and FIG. 4, a cross section of the chute 3 is T-shaped. The chute 3 is formed in the middle of the curved concave surface 2. The chute 3 and the curved concave surface 2 are disposed in parallel. During mounting of the segment single body 1, the length of the projection of the chute 3 in the horizontal direction and the length of the projection of the curved concave surface 2 are disposed to be the same. The length of the projection of the chute 3 in the vertical direction and the width of the projection of the curved fixing member 4 in the vertical direction are disposed to be the same.

[0032] The curved fixing member 4 is made of conductive spring steel. The thickness of the curved fixing member 4 is 2 to 4 mm. A nock of the curved fixing member 4 faces one end distal from the slider 32.

[0033] An elastic fixing piece 33 used for fixing the elastic member 31 is fixedly connected to the middle of the chute 3. Two ends of the chute 3 are fixedly connected to baffles 34 used for limiting sliding in the chute 3.

[0034] A working condition and principle of the embodiments are as follows.

[0035] During application of a grounding segment used in a segmented grounding body, two segment single bodies 1 are clamped on the exterior of a grounding conductor. A locking bolt is threaded through a through hole 5 to gradually tighten the two groups of segment single bodies 1. In a tightening process, a curved fixing member 4 deforms under an extrusion force of the grounding conductor, thereby being gradually stretched to clamp the grounding conductor. The slider 32 slides along with the curved fixing member 4, and the elastic member 31 is compressed, so that a joint area between the curved fixing member 4 and the grounding conductor is larger. The elastic member 31 is compressed and provides a reaction force for the slider 32, so that the curved fixing member 4 fits the grounding conductor tightly. Both the curved fixing member 4 and the slider 32 are conductors, thereby transferring chargers on the grounding conductor to the segment single body 1. The grounding segment adopts a split structure, thereby being relatively convenient to transport and mount. During mounting, because the size of the segment single body 1 is smaller than that of an entire grounding segment, the grounding segment can be conveniently buried in the ground for mounting, thereby reducing an excavation area. Meanwhile, the flexibility of the curved fixing member 4 is improved, thereby enabling the curved fixing member 4 to be applicable to grounding conductors of different sizes, and improving the universality of the grounding segment.
