[0026] A lightning protection grounding device for a photovoltaic power station includes a support rod 1, with a lightning rod 2 connected to the top of the support rod 1. Support components 3 are arranged on both sides of the support rod 1. Each support component 3 includes arc-shaped sleeve plates 301 arranged on both sides of the outer wall of the support rod 1. Support shafts 302 are rotatably connected to the opposite sides of the two arc-shaped sleeve plates 301. Support plates 303 are rotatably connected to the opposite ends of the two support shafts 302. Reinforcing components 4 are symmetrically arranged on the top sides of the two support plates 303, away from the support shafts 302. Each reinforcing component 4 includes a mounting bracket 401 on the top of the support plate 303. Both sides of the mounting bracket 401 are fixedly connected to the top of the support plate 303. The top of the inner side of the mounting bracket 401 is rotatably connected to the lead screw 402 via bearings. A reinforcing sleeve 403 is provided on the outside of the lead screw 402. A driven gear 404 is fixedly connected to the top of the outer wall of the lead screw 402. Guide blocks 405 are fixedly connected to the top of the outer walls on both sides of the support plate 303. Guide rods 406 pass through the interior of the two guide blocks 405. A rotating rod 408 passes through the top of the mounting bracket 401 on the side away from the lead screw 402. A drive gear 407 is fixedly connected to the bottom of the rotating rod 408. A handwheel 409 is fixedly connected to the top of the rotating rod 408.

[0027] The inner walls of the two arc-shaped sleeves 301 are tightly attached to the outer wall of the support rod 1. The two ends of the two arc-shaped sleeves 301 are connected by fastening bolts. The inner wall of the reinforcing sleeve 403 has a threaded groove and is threaded to the outer wall of the lead screw 402. The bottom end of the reinforcing sleeve 403 is tapered and passes through the support plate 303. The outer walls of the two guide rods 406 are slidably connected to the inner walls of the two guide blocks 405 respectively. The bottom ends of the two guide rods 406 are fixedly connected to the top of the support plate 303. The outer wall of the rotating rod 408 is rotatably connected to the inner wall of the mounting bracket 401. The driving gear 407 and the driven gear 404 are meshed.
