Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view at a in fig. 1.
In the figure: 1-guide head, 2-grounding rod, 3-pin shaft, 4-steel sleeve, 5-deformation part, 6-silver sheet, 7-suspension ring, 8-conical wedge block, 9-anti-theft chain, 10-grounding wire, 11-wiring bolt, 12-radial lancing, 13-inner conical surface section.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, the embodiment includes a grounding rod 2, a steel sleeve 4, a guide head 1, a grounding wire 10 and an antitheft chain 9, wherein the grounding rod 2 and the guide head 4 are both made of copper rods with a diameter of 30mm, so as to ensure the effectiveness of grounding. During specific implementation, the grounding rod 2 can adopt a segmented structure to improve portability, and all the segments are connected into a whole through threads.
As shown in figure 1, the steel bushing 4 suit is in the upper end of earth rod 2, installs the utility model discloses the time, the mode of accessible hammering steel bushing 4 will guide head 1 and earth rod and wedge in subaerial mounting hole. The steel bushing 4 is connected with the grounding rod 2 through the shaft hole in an interference fit mode, so that the connection strength between the steel bushing 4 and the grounding rod 2 can be effectively guaranteed, and the resistance of the contact surface between the steel bushing 4 and the grounding rod 2 is reduced. The lower extreme of guide head 1 through threaded connection at earth bar 2, the lower extreme processing of guide head 1 has the taper structure, resistance when effectively reducing the installation.
As shown in fig. 1, one end of the grounding wire 10 is fixed on the steel sleeve 4 through a wiring bolt 11, and the other end is connected to the equipment to be ground protected, so that a reliable current path is established between the grounding rod 2 and the equipment to be ground protected.
The one end welding of theftproof chain 9 on the steel bushing 4, another section welding can effectively prevent through setting up of theftproof chain 9 on by ground protection's equipment the utility model discloses it is stolen.
The up end of steel bushing 4 is the plane, and the side of steel bushing 4 upper end articulates there is link 7, and when equipment shifted, hook link 7 through the lifting hook on the hoisting equipment, can swiftly will the utility model discloses extract in the follow soil.
The steel sleeve 4 is connected with the grounding rod 2 through the pin shaft 3, and the connection strength between the steel sleeve 4 and the grounding rod 2 is further guaranteed. The wiring bolt 11 is made of brass, and the wiring bolt 11 is connected with the grounding rod 2 through threads. By this connection, virtual connection between the ground wire 10 and the ground rod 2 is effectively avoided.
The center at the top of the grounding rod 2 is provided with a conical hole, the inner side of the steel sleeve 4 is provided with a conical wedge 8 corresponding to the conical hole, four radial slits 12 are processed at the top of the grounding rod 2, the top of the grounding rod 2 is equally divided into four deformation parts 5 with the same size by the four radial slits 12, the four deformation parts 5 are outwards expanded after the conical wedge 8 is wedged into the conical hole, the inner side of the grounding rod 2 is provided with an inner conical surface section 13 used for accommodating the expanded deformation parts 5, the large-diameter end of the inner conical surface section 13 faces upwards, the small-diameter end faces downwards, and the outer side of the expanded deformation part 5 is tightly attached to the inner wall of the inner conical surface section 13.
