First, the internal thread 10 of the first steel pipe 2 is rotationally connected to the external thread 9 of the second steel pipe 3, and then the internal thread 10 of the second steel pipe 3 is rotationally connected to the external thread 9 of the third steel pipe 4, making the connection between the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 tighter. A lightning protection ball 5 is installed at the top of the first steel pipe 2, and a lightning arrester 6 is installed at the top of the lightning protection ball 5. The lightning arrester 6 is conical to absorb electric shock, while the lightning protection ball 5 can store the current inside, thus preventing the current from spreading. Moreover, the first steel pipe 2, the lightning protection ball 5 and the lightning arrester 6 are integrally designed. The bottom end of the lightning protection ball 5 is welded with a ground wire 14, and the bottom end of the ground wire 14 is connected to the earth electrode 15, enabling the current to be introduced into the earth electrode 15 through the ground wire 14, so that the current can be dispersed through the earth. First convex blocks 7 and second convex blocks 8 are respectively installed at both ends of the second steel pipe 3, and the second steel pipe 3, the first convex blocks 7 and the second convex blocks 8 are integrally designed. Moreover, the first convex blocks 7 are installed at the top end of the third steel pipe 4, and the second convex blocks 8 are installed at the bottom of the first steel pipe 2. External threads 9 are provided on the outer walls of the first convex blocks 7, and internal threads 10 corresponding to the external threads 9 are provided on the inner walls of the second convex blocks 8, enabling the connection between two steel pipes through the external threads 9 and the internal threads 10, making it more stable. Installation holes 13 are provided on both the first convex blocks 7 and the second convex blocks 8, and the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 are fixedly connected through the long bolts 11 and the short bolts 12 passing through the installation holes 13. Connecting with the long bolts 11 and the short bolts 12 can make the connection between the steel pipes more firm, thus preventing the lightning rod 1 from breaking. Then, the lightning rod 1 is set upright. After alignment, the third steel pipe 4 is connected to the support steel plate 101 and welded to the support steel plate 101. A rib plate 103 is installed on the support steel plate 101, and the support steel plate 101 is connected to the rib plate 103. Moreover, the support steel plate 101 is fixed by anchor bolts 102, making the foundation of the lightning rod 1 more firm, thus avoiding the phenomenon of the lightning rod 1 collapsing.

[0028] Please refer to Figure 1 and Figure 2 , the diameters of the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 are the same, and the diameters of the first convex blocks 7 and the second convex blocks 8 are the same, so that the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 will not be easily blown down by the wind.

[0029] Please refer to Figure 1 - Figure 4 , the diameter of the lightning protection ball 5 is larger than that of the first steel pipe 2, and the lightning arrester 6 is conical. The lightning arrester 6 is conical to absorb electric shock, while the lightning protection ball 5 can store the current inside, thus preventing the current from spreading.

[0030] Please refer to Figure 1 -Figure 4 , the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 are connected by the first convex block 7, the second convex block 8, the long bolts 11 and the short bolts 12, and multiple groups of long bolts 11 are installed staggeredly. Through the connection of the long bolts 11 and the short bolts 12, the connection between the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 is made more compact.

[0031] Please refer to Figure 1 - Figure 4 , the long bolts 11 and the short bolts 12 have the same diameter, and the length of the long bolts 11 is greater than the length of the second steel pipe 3. The length of the long bolts 11 can connect the two steel pipes with an intermediate interval, making the connection between the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 more integrated.

[0032] Please refer to Figure 2 - Figure 3 , through holes corresponding to the long bolts 11 and the short bolts 12 are respectively drilled through the first convex block 7 and the second convex block 8, and the through holes 13 and the external threads 9 drilled on the first convex block 7 correspond to the through holes 13 and the internal threads 10 on the second convex block 8 in position. This can make the long bolts 11 and the short bolts 12 firmly connected to the first steel pipe 2, the second steel pipe 3 and the third steel pipe 4 without the bolts falling off.

[0033] The working principle of the present utility model is as follows: When the user assembles the lightning rod 1, first fixedly connect the support steel plate 101 to the pre-buried anchor bolts 102, weld a rib plate 103, and then assemble the lightning rod 1. First, rotatably connect the first steel pipe 2 and the second steel pipe 3 through the external thread 9 and the internal thread 10 of the first convex block 7 and the second convex block 8, and then rotatably connect the second steel pipe 3 and the third steel pipe 4 through the external thread 9 and the internal thread 10 of the first convex block 7 and the second convex block 8. After the connection is completed, insert the long bolts 11 and the short bolts 12 into the respective installation holes 13 and perform connection and fixation. The connection between the second steel pipe 3 and the second steel pipe 3 is carried out in the same way. The first steel pipe 2, the lightning protection ball 5 and the lightning arrester 6 are integrally produced. Then, weld the ground wire 14 to the lightning protection ball 5, and at the same time, weld the ground wire 14 to the ground electrode 15. Then weld a rib plate 103 to the support steel plate 101, then erect the lightning rod 1, straighten and align it, then connect and fix the lightning rod 1 to the support steel plate 101 and then correct it, and weld the other three rib plates 103. When lightning strikes, the lightning arrester 6 will receive the lightning strike, and conduct the lightning strike through the lightning protection ball 5 into the ground wire 14, then through the ground wire 14 into the ground electrode 15, and then through the ground electrode 15 to disperse the current in the ground.
