[0002] Towers are important infrastructure in fields such as communications and power transmission. They can be used to erect communication antennas, power lines, etc., to achieve signal coverage or long-distance power transmission. Because towers are usually quite tall, they are easy targets for lightning strikes. The powerful current generated by lightning can damage the equipment on the tower, or even cause fires and threaten personnel safety. Therefore, it is necessary to install lightning protection facilities such as lightning rods, down conductors, and grounding devices to conduct lightning current into the ground, avoid equipment damage, and ensure the safe and stable operation of towers and related systems.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Reference Figure 1-6A lightning protection grounding structure for iron towers includes a support platform 1, a support frame 2 fixedly connected to the top of the support platform 1, a control console 3 fixedly connected to the top of the support frame 2, a lightning arrester 4 fixedly connected inside the control console 3, and a lifting assembly inside the control console 3. The lifting assembly includes a telescopic groove 301, a limiting slide groove 302, a transmission disc 303, a handle 304, a lead screw 305, a telescopic rod 306, a limiting slide bar 307, and a threaded groove 308. The telescopic groove 301 is formed inside the control console 3, limiting the... The slide groove 302 is formed on the inner wall of the telescopic groove 301. The transmission disc 303 is rotatably connected to the bottom of the telescopic groove 301. The handle 304 is rotatably connected to the bottom of the transmission disc 303. The lead screw 305 is fixedly connected to the top of the transmission disc 303 and located inside the telescopic groove 301. The telescopic rod 306 is fixedly connected to the bottom of the lightning arrester 4 and located inside the telescopic groove 301. The limiting slide bar 307 is fixedly connected to the outside of the telescopic rod 306. The threaded groove 308 is formed at the bottom of the telescopic rod 306.

[0027] The lifting assembly allows the operator to rotate the transmission disc 303 by cranking the handle 304. This rotation of the transmission disc 303 simultaneously rotates the lead screw 305. As the lead screw 305 rotates, the limiting groove 302 limits the limiting slide bar 307, and the telescopic rod 306 is threadedly connected to the lead screw 305 via a threaded groove 308. This causes the telescopic rod 306 to move upwards, thus simultaneously raising the lightning arrester 4. This invention, through the lifting assembly, allows the lead screw 305 to rotate while simultaneously raising the telescopic rod 306, thereby achieving height adjustment of the lightning arrester 4. This effectively improves convenience and practicality, facilitating the operator's adjustment work.

[0028] Furthermore, inside the support platform 1 and outside the telescopic groove 301, auxiliary holes 5 are arranged in a ring array. A down conductor 6 is fixedly connected to the side surface of the lightning arrester 4, and the down conductor 6 is located inside the auxiliary hole 5. An insulating sleeve 7 is sleeved on the outside of the down conductor 6, and a grounding rod 8 is fixedly connected to the end of the down conductor 6 away from the lightning arrester 4.

[0029] In this invention, when lightning strikes the lightning arrester 4 and releases current, the current is conducted along the down conductor 6 to the grounding rod 8, and then through the grounding rod 8 to the ground, thus protecting the tower. The installation of the insulating sleeve 7 not only protects the down conductor 6, but also prevents the current from spreading.

[0030] Furthermore, a connecting component is provided inside the grounding rod 8 and outside the lead wire 6. The connecting component includes a connecting groove 801, a threaded groove 802, a helical spring 803, and an adapter thread 804. The connecting groove 801 is opened inside the grounding rod 8.

[0031] The second threaded groove 802 is formed on the inner wall of the connecting groove 801. The helical spring 803 is fixedly connected to the bottom of the connecting groove 801. The adapter thread 804 is formed on the outer side of the down conductor 6. The end of the down conductor 6 away from the lightning arrester 4 is threadedly connected to the second threaded groove 802 through the adapter thread 804.

[0032] The connection component is designed so that workers can connect one end of the down conductor 6 into the connecting groove 801 inside the grounding rod 8, and then rotate the grounding rod 8 to achieve a threaded connection through the adapter thread 804 and the threaded groove 802. The installation of the helical spring 803 further enhances the tightness of the connection between the down conductor 6 and the grounding rod 8. This invention, through the design of the connection component, not only effectively improves the tightness of the connection between the down conductor 6 and the grounding rod 8, but also facilitates the replacement or maintenance of the grounding rod 8, thereby significantly improving its ease of use and practicality.

[0033] Furthermore, the support frame 2 is internally fixedly connected with connecting rods 9, and the bottom of the support platform 1 is fixedly connected with support columns 10 in a circular array. The bottom of the support columns 10 is fixedly connected with mounting blocks 11.

[0034] The down conductor 6 and the grounding rod 8 pass through the interior of the mounting block 11. The installation of the mounting block 11 and the support column 10 not only provides support for the device, but also makes it convenient for workers to install the device on the top of the tower.

[0035] Furthermore, the telescopic rod 306 is threadedly connected to the lead screw 305 through the threaded groove 308, and the limiting slide 307 is adapted to the limiting slide groove 302.

[0036] In summary:

[0037] In use, the worker first connects one end of the down conductor 6 into the connecting groove 801 inside the grounding rod 8, and then rotates the grounding rod 8 to make a threaded connection with the threaded groove 802 through the adapter thread 804. Then the device is installed on the top of the iron tower through the mounting block 11; and the grounding rod 8 is buried in the soil through the iron tower.

[0038] Afterwards, the staff can crank the handle 304 to make the handle 304 drive the transmission plate 303 to rotate. During the rotation of the transmission plate 303, the lead screw 305 can be rotated synchronously. When the lead screw 305 rotates, due to the limiting slide groove 302 limiting the limiting slide bar 307 and the threaded connection between the telescopic rod 306 and the lead screw 305 through the threaded groove 308, the telescopic rod 306 is driven to move upward. During the movement of the telescopic rod 306, the lightning arrester 4 can be driven to rise synchronously, thereby realizing the adjustment of the height of the lightning arrester 4.

[0039] Finally, when lightning strikes the lightning arrester 4 and releases current, the current will be conducted along the down conductor 6 to the grounding rod 8, and then conducted to the ground through the grounding rod 8, thus protecting the tower.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
