Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically a multi-directional lightning protection device. Background Technology

[0002] In modern power systems, communication base stations, and high-rise buildings, lightning strikes have become a significant factor affecting equipment safety and system stability. Traditional lightning protection devices (such as single lightning rods and simple grounding systems) are mainly based on the principle of "lightning interception-diversion-discharge," attracting lightning and conducting it to the ground through the tip discharge effect. However, these methods have significant technical limitations.

[0003] With the large-scale construction of new energy power plants (such as wind farms and photovoltaic power plants), their distributed layout and towering structures (such as hundred-meter-high wind turbine towers) exacerbate the risk of lightning strikes. Traditional protection solutions, due to their unidirectional protection characteristics, are unable to cope with multi-directional lightning intrusions in complex terrain. Although there are improved solutions such as array-type lightning rods and surge protectors in existing technologies, the lack of systematic coupling design between components makes it impossible to achieve gradient dissipation and multi-path conduction of lightning energy, resulting in insufficient protection effectiveness.

[0004] Therefore, this utility model provides a multi-directional lightning protection device. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a multi-directional lightning protection device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-directional lightning protection device of this utility model includes a mounting plate, an insulator string, and a support component on the top of the mounting plate; a conductive component on the top of the fixing plate, and a lightning protection component on the top of the fixing plate; a pressure reducing mechanism on the top of the fixing plate; and an insulator string fixedly installed on the top of the mounting plate; the insulator string can block the current and prevent the current from being conducted to the mounting plate, thereby generating unknown safety hazards.

[0007] Preferably, the support assembly includes a support rod and a fixing plate. Two sets of support rods are provided, and the two sets of support rods are fixedly installed on both sides of the top of the mounting plate. The fixing plate is fixedly installed on the top of the insulator string. The side of the support rod away from the mounting plate is fixedly installed with the fixing plate. In this scheme, the cooperation of the support rod and the fixing plate can provide stable support for the guide block and prevent it from being damaged by excessive wind at high altitudes.

[0008] Preferably, the conductive component includes a conductive block and a ceramic column. The conductive block is fixedly installed on the top of the fixed disk, and the top of the conductive block is fixedly installed with the ceramic column. In this scheme, the combined use of the conductive block and the ceramic column can reduce the current and conduct the reduced current to the grounding body.

[0009] Preferably, the lightning protection assembly includes a resistor block and a lightning rod. The resistor block is fixedly installed on the top of the ceramic column, and the top of the resistor block is fixedly installed with the lightning rod. In this scheme, the resistor block can slow down the current flow and reduce a portion of the voltage, while the lightning rod can absorb lightning strikes.

[0010] Preferably, the voltage reduction mechanism includes a conductive rod, a first conductive ring, a connecting rod, an inclined rod, and a second conductive ring. The conductive rod is fixedly installed on the top of the ceramic column. Several sets of the first conductive rings are provided, with the sides of the several sets of first conductive rings close to each other fixedly installed with the connecting rod. The top of the conductive rod is fixedly installed with the first conductive ring, the top of the first conductive ring is fixedly installed with the inclined rod, and the surface of the inclined rod is fixedly installed with the second conductive ring. The lightning rod is located on the inner wall of the first and second conductive rings. In this scheme, the coordinated use of the conductive rod, the first conductive ring, the connecting rod, the inclined rod, and the second conductive ring can absorb the current inside the lightning rod and generate an electric arc to dissipate the voltage when the current passes through the lightning rod.

[0011] Preferably, one side of the conductor block is fixedly installed. This design can guide the power after being stepped down layer by layer to the ground, thereby releasing the voltage and preventing current accumulation from damaging electrical appliances.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 3As shown in the embodiment of this utility model, a multi-directional lightning protection device includes a mounting plate 1, an insulator string 20, and a grounding electrode 70. A support assembly 3 is provided on the top of the mounting plate 1. A conductive assembly 4 is provided on the top of the fixing plate 32, and a lightning protection assembly 5 is provided on the top of the fixing plate 32. A pressure reducing mechanism 6 is provided on the top of the fixing plate 32. The insulator string 20 is fixedly installed on the top of the mounting plate 1. The support assembly 3 includes a support rod 31 and a fixing plate 32. Two sets of support rods 31 are provided, and the two sets of support rods 31 are fixedly installed on both sides of the top of the mounting plate 1. The fixing plate 32 is fixedly installed on the top of the insulator string 20. The side of the support rod 31 away from the mounting plate 1 is fixedly installed with the fixing plate 32. The conductive assembly 4 includes a conductor block 41 and a ceramic column 42. The conductor block 41 is fixedly installed on the top of the fixing plate 32, and the top of the conductor block 41... The lightning protection assembly 5 includes a resistor block 51 and a lightning rod 52. The resistor block 51 is fixedly installed on the top of the ceramic column 42, and the top of the resistor block 51 is fixedly installed with the lightning rod 52. The voltage reduction mechanism 6 includes a conductive rod 61, a first conductive ring 62, a connecting rod 63, an inclined rod 64, and a second conductive ring 65. The conductive rod 61 is fixedly installed on the top of the ceramic column 42. Several sets of first conductive rings 62 are provided. The side of several sets of first conductive rings 62 that are close to each other is fixedly installed with the connecting rod 63. The top of the conductive rod 61 is fixedly installed with the first conductive ring 62. The top of the first conductive ring 62 is fixedly installed with the inclined rod 64. The surface of the inclined rod 64 is fixedly installed with the second conductive ring 65. The lightning rod 52 is located on the inner wall of the first conductive ring 62 and the second conductive ring 65. One side of the conductive block 41 is fixedly installed with the grounding body 70.

[0024] like Figures 1 to 3 As shown, the insulator string 20 can block the current and prevent the current from being conducted to the mounting plate 1, thus creating unknown safety hazards. The cooperation between the support rod 31 and the fixing plate 32 can provide stable support for the conductor block 41, preventing it from being damaged by excessive wind at high altitudes. The cooperation between the conductor block 41 and the ceramic column 42 can reduce the current and conduct the reduced current to the grounding body 70. The resistor block 51 can slow down the current flow and reduce some of the voltage. The lightning rod 52 can absorb lightning strikes. The cooperation between the conductive rod 61, the first conductive ring 62, the connecting rod 63, the diagonal rod 64, and the second conductive ring 65 can absorb the current inside the lightning rod 52 and generate an arc to dissipate the voltage when the current passes through the lightning rod 52. The grounding body 70 can conduct the power after being reduced through layers to the ground, thereby releasing the voltage and preventing the power accumulation from causing damage to electrical appliances.

[0025] Working principle: During operation, first install the mounting plate 1 to the usage position, then connect the grounding electrode 70 to the grounding electrode or drive it directly into the ground, and then it can be used. When lightning strikes, the current will first strike the lightning rod 52, and then the current will be conducted downward through the lightning rod 52. When the current passes through the lightning rod 52, because the second conductive ring 65 and the first conductive ring 62 are conductive, the voltage inside the lightning rod 52 will be absorbed by the first conductive ring 62 and the second conductive ring 65, thereby generating an electric arc. During the generation of the electric arc, the voltage inside the lightning rod 52 will be consumed. As the current continues to be conducted, it will enter the resistor block 51. Since the resistor block 51 has a certain blocking ability and does not affect the current flow, the current will be consumed again when passing through the resistor block 51. When the current reaches the ceramic column 42, the voltage will drop sharply again due to the poor conductivity of the ceramic column 42. Then the ceramic column 42 will transmit the remaining power to the conductor block 41, and the conductor block 41 will conduct the remaining current to the ground through the grounding electrode 70 and release it. Thus, the protection of the electrical components is completed.
