Description

Technical Field

[0001] This utility model relates to the field of lightning protection device technology, and in particular to a lightning protection device for a broadcast television signal transmission tower. Background Technology

[0002] Transmission towers are usually located at high altitudes, making them easy targets for lightning strikes. Lightning arresters in lightning protection systems can attract lightning and divert the lightning current to the ground, preventing lightning from directly striking the main structure of the transmission tower, transmitting antennas, feeders, and various electronic devices. This prevents these devices from being damaged by lightning strikes and ensures the normal operation of the broadcast television signal transmission system.

[0003] A search revealed a lightning protection device for a broadcast television signal transmission tower (publication number CN218415338U). The device includes a main body and a mounting base for fixing to the transmission tower. The lower end of the main body is threadedly connected to a snap-fit ​​sleeve. The upper end of the outer surface of the snap-fit ​​sleeve has an annular limiting block, and the lower end of the snap-fit ​​sleeve has an annular groove corresponding to the limiting block. An adapter seat is provided between the snap-fit ​​sleeve and the mounting base. The upper end of the inner surface of the adapter seat has an annular guide groove, and the lower end of the guide groove connects to a limiting groove. An air ring is provided at the lower end of the inner cavity of the adapter seat. Inside the air ring, an annular sleeve is provided, communicating with the interior of the air ring. A rod is movably inserted into the inner end of the sleeve. A stop sleeve is provided in the middle of the rod, and a return spring is movably sleeved on the rod. The rod is movably inserted into a insertion hole. This application not only facilitates the disassembly and maintenance of the lightning protection device but also improves the stability of the lightning protection device when used outdoors.

[0004] Based on the aforementioned patent, the background technology mentioned above states that the device is installed behind the broadcast television signal transmission tower, which is inconvenient to disassemble and causes great inconvenience to maintenance.

[0005] In response to the technical problem of the inconvenience of disassembling and assembling lightning protection devices, this application proposes a lightning protection device for broadcast television signal transmission towers. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4As shown, one embodiment of this utility model provides a lightning protection device for a broadcast television signal transmission tower, comprising a base 1, a knob 2 rotatably connected to the inner wall of the base 1, a rotating ring 5 disposed at the rear end of the knob 2, a lightning rod 10 disposed on the inner wall of the rotating ring 5, a gear 3 fixedly connected to the rear end of the knob 2, a toothed ring 4 meshing with the outer wall of the gear 3, the top end of the toothed ring 4 fixedly connected to the bottom end of the rotating ring 5 for driving the rotating ring 5 to rotate, rotating rods 6 rotatably connected to all four sides of the inner wall of the rotating ring 5, and locking blocks 7 rotatably connected to the other end of each rotating rod 6, the outer walls of the locking blocks 7 being slidably connected to the inner wall of the base 1, and the lightning rod 10. A mounting base 8 is fixedly connected to the bottom. The mounting base 8 has slots 9 on all four sides of its outer wall. The outer walls of the locking blocks 7 are all set on the inner walls of the slots 9. The shape of the locking blocks 7 matches the slots 9 for the installation and removal of the lightning rod 10. A fixing ring 13 is fixedly connected to the inner wall of the base 1. A limiting groove 14 is opened on the inner wall of the fixing ring 13. A limiting ring 12 is set on the inner wall of the limiting groove 14. The shape of the limiting ring 12 matches the limiting groove 14. The inner wall of the limiting ring 12 is slidably connected to the outer wall of the knob 2. A spring 11 is fixedly connected to the outer wall of the knob 2. The other end of the spring 11 is fixedly connected to the front end of the limiting ring 12 for limiting the knob 2.

[0027] Specifically, during disassembly, simply pull the limiting ring 12 and turn the knob 2 to remove the four side clips 7 from the slots 9, thus removing the lightning rod 10 and mounting base 8 from the base 1 and completing the disassembly. By turning the knob 2, the four side clips 7 can be removed from the slots 9, facilitating the disassembly and assembly of the lightning rod 10. The operation is simple and convenient, allowing for the quick removal of damaged lightning rods 10 and timely replacement with new ones, avoiding a decrease in lightning protection effectiveness due to untimely maintenance and ensuring the safety of the transmission tower during thunderstorms.

[0028] Reference Figure 2 and Figure 5 As shown, the outer wall of the rotating ring 5 is rotatably connected to the inner wall of the base 1. Buffer blocks 15 are slidably connected to all four sides of the inner wall of the base 1. A damping rod 17 is fixedly connected to one end of each buffer block 15. A spring 16 is sleeved on the outer wall of the damping rod 17. The other end of the damping rod 17 is fixedly connected to the inner wall of the base 1.

[0029] Specifically, the diameter of the inner wall on the upper side of the base 1 is larger than that of the lightning rod 10. At the same time, a wind deflector can be installed on the upper side of the base 1 to prevent rainwater from entering the base 1 and affecting its service life. By setting buffer structures on the four sides of the lightning rod 10, the mechanical energy generated by the wind can be absorbed to a certain extent in windy weather, reducing the stress on the lightning rod 10, protecting the structural integrity of the lightning rod 10, and improving its service life.

[0030] Working principle: First, when installing the lightning rod 10, pull the limiting ring 12 forward to remove it from the limiting groove 14, releasing the limitation on the knob 2. Then, rotate the knob 2. The knob 2 drives the gear 3 to rotate, the gear 3 drives the gear ring 4 to rotate, and the rotating ring 5 to rotate. The rotating ring 5 drives the rotating rods 6 on the four sides of the inner wall to rotate, and drives the locking block 7 to slide inward. Then, insert the mounting base 8 into the base 1 and align the locking groove 9 with the locking block 7. After installation, rotate the knob 2 in the opposite direction to lock the locking blocks 7 on the four sides into the locking groove 9 and release the limiting ring 12. The limiting ring 12 is then locked into the limiting groove 14 by the spring 11, thus completing the installation. Secondly, when the lightning rod 10 is used in windy weather, it will swing to any side. While swinging, it will drive the buffer block 15 to slide outward. The damping rod 17 and the spring 16 will buffer it and protect the lightning rod 10.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
