[0024] Embodiment:

[0025] As Figures 1 to 3 shown, a lightning protection device for a communication tower proposed by the present utility model includes a support frame 1 connected to the top of the communication tower. At the bottom of the support frame 1, there are a plurality of fixing mechanisms 11 distributed in a circumferential array to install the support frame 1 on the top of the communication tower. It further includes: a first lightning rod 3, a second lightning rod 4, and a third lightning rod 5 that are fixedly installed on the top of the support frame 1 and sleeved and spirally connected in sequence; a spiral connection block 451 provided at one end of the second lightning rod 4 and the third lightning rod 5. The function of the spiral connection block 451 is to make the connection ends of the first lightning rod 3 and the second lightning rod 4, and the second lightning rod 4 and the third lightning rod 5 be spirally sleeved. The spiral connection block 451 is inserted into the inner parts of one ends of the first lightning rod 3 and the second lightning rod 4, and a buckle mechanism for prompting the completion of installation is provided. The function of the buckle mechanism is that after the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 are spirally connected, the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 cannot be telescoped through the buckle mechanism, and can only maintain the maximum length after being opened. The function is to prevent loosening between the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5; a water flow hole 341 is opened at the bottom of the first lightning rod 3 and the second lightning rod 4 to drain the water in the first lightning rod 3 and the second lightning rod 4 by the action of gravity. The function of the water flow hole 341 is to prevent rainwater from accumulating in the second lightning rod 4 and the third lightning rod 5 and being unable to be discharged, which may eventually cause the second lightning rod 4 and the third lightning rod 5 to be rusted due to long-term immersion in water.

[0026] Furthermore, the buckle mechanism includes telescopic grooves 343 opened on the inner walls of the tops of the first lightning rod 3 and the second lightning rod 4. A push spring 344 is fixedly connected inside each telescopic groove 343. The function of the push spring 344 is that after the spiral connection block 451 moves to the designated installation position, it will be automatically locked, thereby preventing loosening between the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5. One end of the push spring 344 away from the inner wall of the telescopic groove 343 is fixedly connected with a telescopic latch 345. Hemispherical plugs are provided at one ends of the telescopic latch 345 inserted into the fixed card slots 452. The function of the hemispherical plugs is to make it easier and faster for the telescopic latch 345 to be inserted into the fixed card slots 452. A plurality of fixed card slots 452 distributed in a circumferential array for the ends of the telescopic latch 345 to be inserted into are opened on the outer wall of the bottom end of the spiral connection block 451.

[0027] Among them, anti - detachment heads 453 for preventing the second lightning rod 4 from coming out of the first lightning rod 3 and the third lightning rod 5 from coming out of the top of the second lightning rod 4 are provided at one ends of the spiral connection block 451 inserted into the first lightning rod 3 and the second lightning rod 4. One of the spiral connection blocks 451 is fixedly connected to the bottom end of the second lightning rod 4, and the other spiral connection block 451 is fixedly connected to the bottom end of the third lightning rod 5.

[0028] Secondly, a conical water guide block 342 for automatically draining the water inside the first lightning rod 3 and the second lightning rod 4 to the water flow hole 341 is fixedly connected to the inner bottom wall of the first lightning rod 3 and the second lightning rod 4. The function of the conical water guide block 342 is that the water entering the first lightning rod 3 and the second lightning rod 4 cannot stay for a long time and can flow out through the water flow hole 341.

[0029] Furthermore, the bottom end of the first lightning rod 3 is fixedly connected to a mounting base plate 2, and the top of the support frame 1 is fixedly connected to a fixed base plate 12. A plurality of bolt holes 21 distributed in a circumferential array are formed in both the fixed base plate 12 and the mounting base plate 2, and the bolt holes 21 on the fixed base plate 12 and the mounting base plate 2 are fixedly connected by a plurality of mounting bolts 22.

[0030] The working principle in this embodiment is as follows: When the lightning protection device for a communication tower is needed, as Figure 1 shown, the support frame 1 is installed on the top of the communication tower through a plurality of fixing mechanisms 11 at the bottom of the support frame 1. Then, the staff needs to climb to the top of the communication tower with the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5, and when installing the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 on the fixed base plate 12 on the support frame 1. Only by making the second lightning rod 4 extend into the first lightning rod 3 and the third lightning rod 5 extend into the second lightning rod 4, when the staff carries the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5, they only need to carry the length of the first lightning rod 3, which is convenient and easy to operate, thus avoiding the inconvenience caused by the excessive length of the lightning protection device. When the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 are carried by the staff to the top of the communication tower, only need to place the end of the first lightning rod 3 away from the mounting base plate 2 in an inverted manner, and the second lightning rod 4 inside the first lightning rod 3 and the third lightning rod 5 inside the second lightning rod 4 will both fall out of the first lightning rod 3 and the second lightning rod 4 due to the action of gravity. Then, by rotating the second lightning rod 4 and the third lightning rod 5 in sequence to drive the spiral connection block 451 at one end to rotate until the anti - detachment chuck 453 at the bottom of the spiral connection block 451 abuts against the inner walls of the tops of the first lightning rod 3 and the second lightning rod 4. At this time, the telescopic chuck 345 can be made to snap into any one of the fixed card slots 452 at the end away from the pushing spring 344 by the elastic thrust of the pushing spring 344 in the telescopic groove 343. Finally, the second lightning rod 4 and the third lightning rod 5 can neither rotate nor shake, so that the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 can be extended to the maximum length. Then, by inserting a plurality of mounting bolts 22 on the mounting base plate 2 and the fixed base plate 12 into the bolt holes 21, the first lightning rod 3, the second lightning rod 4, and the third lightning rod 5 can be firmly installed on the fixed base plate 12 at the top of the support frame 1.
