Description

Technical Field

[0001] The invention relates to the technical field of voltage-equalizing rings for lightning arresters, and in particular to a voltage-equalizing ring for preventing side lightning strikes. Background Art

[0002] The main function of the voltage-grading ring is to prevent lightning from damaging buildings or structures. It protects buildings from direct impacts of lightning by directing lightning on the building to the ground. The voltage-grading ring evenly distributes the potential difference on the surface of the building by setting up ring conductors at certain heights on the building, reducing the risk of electric shock caused by the potential difference. When a lightning strike occurs, the voltage-grading ring can prevent the counter-attack caused by the potential difference, that is, lightning is conducted to the ground through the metal structure (such as steel bars) in the building, which may cause harm to the human body or equipment. The voltage-grading ring effectively reduces the risk of damage to buildings caused by lightning strikes and protects the safety of people and equipment in the building;

[0003] The Chinese patent authorization announcement number is CN118553485B, and its name is a voltage-equalizing ring, which includes a fixing mechanism, a rotating mechanism and a ring body installed on an insulator. The fixing mechanism includes an inner ring and a plurality of limiters installed at the bottom of the inner ring, and extrusion plates carrying evenly arranged tooth grooves are slidably installed in the limiters; it also includes an outer ring rotatably connected to the inner ring, and a spiral protrusion matching the tooth groove is fixedly installed at the bottom of the outer ring, and when the outer ring rotates, the plurality of extrusion plates are close to or away from the insulator; a rotating mechanism is installed above the fixing mechanism, so that when the voltage-equalizing ring is directly blown by strong wind, the sleeve drives the ring body to rotate together, so that the rotating blades and the ring body can play a force-unloading effect, and the force on the connection part between the voltage-equalizing ring and the insulator string is weakened, so that the voltage-equalizing ring is firmly fixed and will not shake, thereby ensuring the uniform effect of the voltage-equalizing ring;

[0004] The shortcomings of the above scheme are: although the above scheme can firmly fix the equalizing ring and prevent it from shaking, the equalizing ring cannot be adjusted during use, and the spacing of the equalizing rings cannot be adjusted according to the structural changes of the building, which may lead to unsatisfactory equalization effect. When in use, birds may leave bird droppings on the equalizing ring. These bird droppings are conductive and may change the electrical properties of the equalizing ring and increase the risk of lightning strikes. In strong winds, the part where the equalizing ring is connected to the building may loosen due to the action of wind, resulting in technical problems such as poor contact at the connection point. Summary of the invention

[0005] The purpose of the present invention is to provide a voltage-equalizing ring for preventing side lightning strikes, so as to solve the problems in the prior art that the voltage-equalizing ring cannot be adjusted during use, and the spacing of the voltage-equalizing ring cannot be adjusted according to the structural changes of the building, which may lead to unsatisfactory voltage-equalizing effect. When in use, birds may leave bird droppings on the voltage-equalizing ring. These bird droppings are conductive and may change the electrical properties of the voltage-equalizing ring, increasing the risk of lightning strikes.

[0020] Beneficial effects of the present invention:

[0021] 1. The main body of the pressure-equalizing ring of the present invention is a semicircular structure.

The rotating ring drives the bird-repelling reflector to rotate, so that the reflective tape and the reflective film on the connecting rod continuously change the reflection angle. These reflective films can reflect light and produce light that interferes with birds. When the reflective tape and the connecting rod rotate, they reflect light and produce dynamic light and shadow effects. The dynamic light and shadow effects can attract the attention of birds better than static light, thereby improving the efficiency of bird repelling.

When pressure is applied to the pressure equalizing ring body, the plug connectors at the two ends of the connecting rod are inserted into the plug-in block. Since the plug connector is a triangular structure, the pressure equalizing ring will not be deformed. This design allows the pressure equalizing ring body to be firmly connected to the mounting plate through the second connecting rod. The triangular structure has high stability due to its geometric characteristics and can effectively disperse and withstand external forces, thereby enhancing the stability of the pressure equalizing ring body and maintaining the overall stability of the system even under strong wind conditions.

The voltage-equalizing ring body 8 is arranged on the mounting plate 19, and is used to guide the lightning current to be safely conducted to the ground, thereby protecting buildings or other structures from damage by lightning strikes. A rotating ring 1 is connected to the outer periphery of the mounting plate 18. The rotating ring 1 is connected to the mounting plate 18 through a rotating mechanism and can rotate around the mounting plate 18. The rotating motor drives the gear 6 to rotate, and the gear 6 engages with the teeth 7 on the rotating ring 1, so that the rotating ring 1 rotates accordingly. The rotation of the rotating ring 1 drives the bird-repelling reflector to rotate. The reflective tape 3 is arranged on the outer periphery of the voltage-equalizing ring body 8, and the connecting rod 4 is affixed with a reflective film.

The mounting plate 18 is provided with a through bolt 23 for fixing the entire equalizing ring system;

[0038] When the wind is strong, it may cause pressure on the pressure equalizing ring body 8. When pressure is applied to the pressure equalizing ring body 8, the plug connector 21 at the end of the connecting rod 20 is inserted into the plug block 22. Since the plug connector 21 is a triangular structure, the pressure equalizing ring 8 will not be deformed. This design allows the pressure equalizing ring body 8 to be firmly connected to the mounting plate 18 through the connecting rod 20, thereby improving the stability of the entire system.
