Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The wire installation assembly 2 includes a connection unit, an expansion unit, a linkage unit, and a sealing unit;

[0034] The connection unit is used to realize the connection between the grounding wire end and the grounding pile 1;

[0035] The expansion unit is used to increase the area of ​​the top of the grounding pile 1 that is hit by the hammer;

[0036] The linkage unit is used to drive the expansion unit to retract when the connection unit is installed;

[0037] The sealing unit is used to perform sealing operations on the connection unit and the expansion unit;

[0038] The connection unit includes a mounting groove 201, a threaded hole 202, and a fixing screw 203;

[0039] The installation groove 201 is formed at the top of the grounding pile 1, and the threaded hole 202 is formed at the bottom end of the inner wall of the installation groove 201;

[0040] The fixing screw 203 is composed of a screw rod 2031 and a round top cap 2032. The round top cap 2032 is fixed to the top of the screw rod 2031, and a through groove 2034 is provided near the edge of the top of the round top cap 2032, which penetrates to the bottom of the round top cap 2032. The grounding wire end passes through the through groove 2034 from the top of the round top cap 2032 and is wound around the outer side of the top of the screw rod 2031. The grounding wire end is connected and fixed to the grounding pile 1 by screwing the screw rod 2031 and the threaded hole 202.

[0041] The expansion unit includes an arc-shaped rotating block 205 and an arc-shaped cushion block 206;

[0042] The arc-shaped rotating block 205 is rotatably mounted on the top of the grounding pile 1 and is provided with a plurality of arc-shaped rotating blocks 205 with the mounting groove 201 as the center circumference. A rotating groove for vertically accommodating and rotating the arc-shaped rotating block 205 is provided at the contact position between the grounding pile 1 and the arc-shaped rotating block 205.

[0043] The arc pad 206 is fixed to the top of the arc rotating block 205. The arc pad 206 in the vertical state fits the top of the grounding pile 1. The arc pad 206 in the horizontal state has its upward end face flush with the top end face of the grounding pile 1. At this time, the arc rotating block 205 is in a horizontal state and the bottom end face of the arc rotating block 205 fits the bottom of the rotating groove. The multiple unfolded arc pads 206 are used to increase the contact surface between the grounding pile 1 and the hammering object when it is hammered.

[0044] The linkage unit includes an annular tooth groove 2033 and a sector-shaped tooth block 207;

[0045] The sector tooth block 207 is fixed to the side of the arc-shaped rotating block 205 facing the inner side of the mounting groove 201, and the annular tooth groove 2033 is opened on the outer side of the circular top cap 2032;

[0046] When the arc-shaped pad 206 is in a horizontal state, the circular top cap 2032 enters the installation groove 201 and meshes with the annular tooth groove 2033. The circular top cap 2032 moves downward to push the multiple sector-shaped tooth blocks 207 to rotate synchronously, so that the multiple arc-shaped pads 206 rotate synchronously to a vertical state.

[0047] The sealing unit includes a connecting piece 204 and an external thread groove 208;

[0048] When the arc-shaped pads 206 are in a vertical state, the external thread grooves 208 are integrally formed on the outer sides of the multiple arc-shaped pads 206, the arc-shaped rotating blocks 205 and the grounding piles 1;

[0049] The connecting piece 204 is composed of an outer sleeve 2041 and a 7-shaped rubber sleeve 2042. The 7-shaped rubber sleeve 2042 is fixed to the top of the outer sleeve 2041. The grounding wire passes through the 7-shaped rubber sleeve 2042 and the outer sleeve 2041 and is connected with the fixing screw 203 in sequence. The inner side of the outer sleeve 2041 is formed with an internal thread groove matching the external thread groove 208. The external thread groove 208 is threadedly connected to multiple arc-shaped pads 206, arc-shaped rotating blocks 205 and the outer side of the grounding pile 1 to achieve sealing of the installation groove 201 area.

[0050] In this embodiment: when installing the grounding pile 1, the plurality of arc-shaped pads 206 and the arc-shaped rotating block 205 are rotated to a horizontal state. At this time, the facing end surface of the arc-shaped rotating block 205 is in contact with the bottom of the rotating groove, thereby limiting the rotation angle of the arc-shaped rotating block 205 so that it can only be rotated to a horizontal state, and at the same time providing support for the arc-shaped rotating block 205;

[0051] Then, the top of the grounding pile 1 is hammered by an external tool to insert the grounding pile 1 deep into the soil. During this process, the multiple arc pads 206 can provide identification coordinates for the hammering operation. Compared with the small-area end of the traditional grounding pile 1, the multiple unfolded arc pads 206 have higher recognition and can better assist the operator to align with the top of the grounding pile 1. At the same time, the external tool will contact the grounding pile 1 and the tops of the multiple arc pads 206 at the same time, so that the hammering force can be better transmitted, and when the external tool is slightly offset, the transmission of the hammering force can also be guaranteed. In addition, it should be supplemented that: when hammering, it is still necessary to align with the top of the grounding pile 1 to avoid directly hammering a single arc pad 206. The arc pad 206 serves more as an auxiliary mark and prevents the tool from offsetting from the top of the grounding pile 1.

[0052] After the grounding pile 1 is inserted to a sufficient depth, the grounding wire end can be passed through the 7-shaped rubber sleeve 2042, the outer sleeve 2041, and the through groove 2034 in sequence, and then the grounding wire end is wrapped around the outer top of the screw rod 2031, and then the screw rod 2031 and the threaded hole 202 are tightened. During this process, the circular top cap 2032 will move down into the installation groove 201. At this time, the annular tooth groove 2033 on the outer side of the circular top cap 2032 is meshed with the fan-shaped tooth block 207. During the process of the circular top cap 2032 rotating and moving down, the circular top cap 2032 can push the fan-shaped tooth block 207 to rotate through the annular tooth groove 2033, and the fan-shaped tooth block 207 drives the arc-shaped rotating block 205 and the arc-shaped cushion block 206 to rotate from a horizontal state to a vertical state. Finally, the circular top cap 2032 presses the grounding wire end tightly inside the installation groove 201, and the arc-shaped cushion block 206 is vertically attached to the top of the grounding pile 1;

[0053] Then, the outer sleeve 2041 is tightened from the top of the multiple arc-shaped pads 206, and finally the outer sleeve 2041 is connected to the outer side of the grounding pile 1 by threads. At this time, the multiple arc-shaped pads 206 and the arc-shaped rotating block 205 are completely received in the inner side of the outer sleeve 2041, so that the sealing protection of the grounding wire end is achieved, and the connection part is effectively prevented from being eroded by rainwater. It should also be noted that the 7-shaped rubber sleeve 2042 fits tightly to the outside of the grounding wire to achieve a good sealing effect.

[0054] Please refer to Figures 1 to 3 The grounding pile 1, the arc-shaped pad 206, the arc-shaped rotating block 205 and the rotating connecting shaft between the arc-shaped rotating block 205 and the grounding pile 1 have high hardness, and when the arc-shaped pad 206 is in a horizontal state, the top horizontal height of the sector tooth block 207 is lower than the top horizontal height of the grounding pile 1.

[0055] In this embodiment: this structure allows the grounding pile 1, arc-shaped pad 206, arc-shaped rotating block 205, and rotating connecting shaft to remain unchanged when subjected to external hammering force, while the fan-shaped tooth block 207 will not be hammered, thereby ensuring the smooth installation of the subsequent fixing screws 203 and connecting parts 204.

[0056] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
