[0044] Working principle of the present invention:

[0045] When in use, a grounding groove is opened on the ground, and then a concrete layer 6 is poured on the inner wall of the grounding groove, and the insulating lightning protection shell 1 is embedded in the concrete layer 6. During the embedding process, the seat edge 101 fixedly arranged on the outer side of the insulating lightning protection shell 1 abuts against the top side of the concrete layer 6, and then the seat edge 101 and the concrete layer 6 are fixedly connected to each other by bolts, and the lightning protection grounding pin 5 is inserted into the inner bottom surface of the grounding groove. After being firmly inserted, the inner support plate 105, the connecting shaft rod 106 and the inner support ring 107 are sent into the insulating lightning protection shell 1, and the upper end of the lightning protection grounding pin 5 is passed through the pinhole at the center position of the inner support plate 105, and then the inner support ring 107 and the insulating lightning protection shell 1 are tightened by the tightening bolts 108, so that the inner support plate 105 limits the limiting boss 502 to achieve the stability of the lightning protection grounding pin 5 inserted in the grounding groove and prevent it from falling off, see the attached manual Figure 3 and Figure 7 As shown, a reserved section is formed at the connection between the lightning conductor 2 and the lightning grounding pin 5, and the lightning conductor 2 above the baffle 901 can be tightened under the elastic force of the spring 9. At this time, the spring 9 is in a compressed state, so that when the lightning conductor 2 is subjected to an external force, the spring 9 can play a certain buffering role, thereby avoiding the problem of breakage and poor contact between the lightning conductor 2 and the lightning grounding pin 5;

[0046] In daily use of the lightning conductor 2, in order to observe the displacement change of the lightning conductor 2, the indicator ring 804 and the displacement column 805 cooperate with each other, so that the displacement column 805 indicates the height change of the indicator ring 804, and cooperates with the telescopic change of the telescopic sheath 802 to achieve the sealing protection of the connection between the lightning conductor 2 and the conical sleeve 801, preventing impurities and rainwater from entering the insulating lightning protection cover 1, and playing a protective role on the lightning protection grounding pin 5, as well as protecting the surrounding people;

[0047] When it is necessary to detect the connection between the lightning conductor 2 and the lightning grounding pin 5, in order to ensure that there is no disconnection or damage between the lightning conductor 2 and the lightning grounding pin 5, the detection head structure 3 can be used for detection. Specifically, the motor 310 drives the detection rotating block 301 to rotate so that the second positioning pin 306 and the socket 110 correspond to each other, and the electric telescopic rod 311 drives the second positioning pin 306 to be inserted into the socket 110, and the two second contact heads 308 are respectively in contact with the third contact head 401 and the fourth contact head 1001, thereby forming a loop among the detection wire, the lightning conductor 2 and the detection light 307. When the loop is complete, the detection light 307 is in In the lit state, when the circuit is disconnected, the detection light 307 is in the off state, so when the light is not on, the cause can be eliminated in time to ensure that the lightning conductor 2 and the lightning grounding pin 5 are in the correct connection state; in the other states, in order to avoid damage to the detection light 307 during thunder, the motor 310 can drive the detection rotating block 301 to rotate, so that the first positioning column 302 and the socket 110 correspond to each other, and the electric telescopic rod 311 drives the first positioning column 302 to be inserted into the socket 110, and the two first contact heads 304 are respectively in contact with the third contact head 401 and the fourth contact head 1001, so that the lightning conductor 2 and the lightning grounding pin 5 are connected to each other.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
