Description
Technical Field
[0001] This utility model relates to the field of lightning protection device technology, specifically a 110kV line lightning protection device. Background Technology
[0002] 110kV lines are high-voltage transmission lines and play an important role in the power system. A 110kV line refers to a power line that transmits 110 kilovolts. Depending on the method of installation, 110kV lines can be divided into overhead lines and cable lines. Overhead lines have conductors erected on poles or towers, while cable lines have conductors wrapped in insulating material and laid underground or underwater. Most existing 110kV line lightning protection devices lack specialized bird protection structures. The main function of lightning protection devices is to protect the line from lightning strikes, but their lack of effective bird protection design increases the possibility of line failure. Utility Model Content
[0003] The purpose of this utility model is to provide a 110kV line lightning protection device to solve the problem mentioned in the background art that most existing 110kV line lightning protection devices lack a dedicated bird protection structure. The main function of lightning protection devices is to protect the line from damage by lightning strikes, but they lack effective bird protection design, which increases the possibility of line failure.

[0026] 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.
[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a 110kV line lightning protection device, comprising: a non-continuing current device 1; a connecting top seat 3 disposed on the top of the non-continuing current device 1; a side fixed support box 4 equidistantly fixed to the outside of the connecting top seat 3; a rotating inner rod 5 rotatably disposed inside the side fixed support box 4; a cam 19 fixedly fixed to the outside of the rotating inner rod 5; bells 18 symmetrically disposed inside the side fixed support box 4, the bells 18 cooperating with the cams 19, and a loudspeaker 23 cooperating with the bells 18 symmetrically fixed to the outside of the side fixed support box 4; a rotating top column 6 rotatably disposed on the top of the side fixed support box 4, the top end of the rotating inner rod 5 fixedly fixed to the rotating top column 6; a fixed side rod 10 equidistantly fixed to the outside of the rotating top column 6, and a wind cup 12 fixedly fixed to one end of the fixed side rod 10; and a third reflector 11 equidistantly fixed to the outside of the fixed side rod 10.
[0028] It is understood that the non-follow-current device 1 of this utility model is a device specifically designed to prevent the generation of continuous power frequency current after the surge arrester or discharge gap is broken down. It ensures that when an overvoltage occurs in the power system, the current path can be quickly cut off after the current is released through the discharge gap, preventing the formation of continuous power frequency follow current and thus avoiding damage to the power system equipment. The grounding device 22, as the core of the lightning protection system, consists of a grounding electrode in contact with the soil and a grounding wire connecting the grounding electrode and the down conductor. The insulator 20 is used to support and fix the conductor and maintain electrical insulation. Disc-type suspension insulators and composite insulators are commonly used in 110kV lines. A parallel gap device 21 is connected to discharge before the insulator 20 during a lightning strike, protecting it from damage. The entire lightning protection device is installed on the 110kV line using a suspension clamp 2. The wind blows the air cup. At 12 o'clock, the wind cup 12 drives the rotating top column 6, rotating rod 7 and rotating inner rod 5 to rotate via the fixed side rod 10. The rotating rod 7 drives the first reflector 8 at the top to rotate, the fixed side rod 10 drives the third reflector 11 to rotate as a whole, and the rotating inner rod 5 drives the second reflector 9 at the bottom to rotate, thus completing the reflection and bird deterrence. At the same time, when the rotating inner rod 5 rotates, it drives the outer cam 19 to rotate. The cam 19 pushes the bell 18, and the bell 18 drives the rotating support block 14 and the rotating rod 15 to rotate within the fixed bracket 13. When the rotating rod 15 rotates, it drives the outer torsion spring 16 to rotate. The torsion spring 16 pushes the limiting block 17, which will reset after the bell 18 is pushed by the cam 19. The sound emitted by the bell 18 is broadcast through the megaphone 23 to drive away nearby birds, effectively preventing birds and avoiding failure of the 110kV line and lightning protection device.
[0029] Please see Figures 1 to 5 A rotating support block 14 is fixedly connected to the top of the bell 18. A rotating rod 15 is fixedly connected inside the rotating support block 14. A fixed bracket 13 is rotatably provided on the outside of the rotating rod 15. The fixed bracket 13 is rotatably connected to the rotating support block 14. The top of the fixed bracket 13 is fixedly connected to the side fixed support box 4.
[0030] It is understood that when the bell 18 of this utility model is pushed, it drives the rotating support block 14 to rotate inside the fixed bracket 13. The rotating support block 14 is rotatably connected to the fixed bracket 13 through the rotating rod 15.
[0031] Please see Figures 1 to 5 A torsion spring 16 is sleeved on the outside of the rotating rod 15. One end of the torsion spring 16 is fixedly connected to the rotating rod 15. A limiting block 17 that cooperates with the torsion spring 16 is symmetrically fixed on the outside of the fixed bracket 13.
[0032] It is understood that when the bell 18 is pushed, the rotating support block 14 and the rotating rod 15 rotate within the fixed bracket 13. When the rotating rod 15 rotates, it drives the torsion spring 16 to rotate synchronously. The rotation position of the torsion spring 16 is restricted by the limiting block 17. When the torsion spring 16 pushes the limiting block 17, it can be reset when the bell 18 is not pushed, thereby resetting the bell 18. The cam 19 pushes the bell 18 multiple times to make a sound to drive away birds.
[0033] Please see Figures 1 to 5 An insulator 20 is provided at the bottom of the non-follow-through device 1. A parallel gap device 21 is provided on the insulator 20. A grounding device 22 is provided at the bottom of the parallel gap device 21. A suspension clamp 2 is provided at the bottom of the grounding device 22.
[0034] It is understood that this utility model connects the entire lightning protection device to the 110kV line through the suspension clamp 2.
[0035] Please see Figures 1 to 5 A rotating rod 7 is fixedly connected to the top of the rotating top column 6, and multiple No. 1 reflectors 8 are fixedly connected at equal intervals to the top of the rotating rod 7.
[0036] It is understood that when the top column 6 and the inner rod 5 are rotated, the rotating rod 7 and the first reflector 8 are rotated to repel birds.
[0037] Please see Figures 1 to 5 Multiple No. 2 reflectors 9 are fixed at equal intervals at the bottom of the rotating inner rod 5.
[0038] It is understood that this utility model uses a first reflector 8 and a second reflector 9 in combination with a third reflector 11 to reflect light and repel birds.
