Description

Technical Field

[0001] This invention relates to the field of lightning protection grounding technology, and in particular to the manufacturing technology of lightning protection grounding devices using novel electrical contact materials, specifically a grounding device for a flexible graphite lightning protection grounding body. Background Technology

[0002] Lightning protection grounding devices are core facilities for protecting electrical equipment, buildings, and personal safety. Their core function is to quickly and safely discharge the surge current generated by lightning into the earth, preventing accidents such as equipment damage, personal injury, and fires. Currently, most existing lightning protection grounding devices use metal grounding electrodes (such as copper rods or galvanized steel pipes) in conjunction with ordinary conductors to achieve grounding. Even though some devices have attempted to use new precious metal materials for electrical contact to manufacture key connection components, their high cost and poor adaptability make them difficult to popularize. Overall, they still have many technical defects and cannot meet the requirements for long-term stable operation in complex environments.

[0003] First, metal grounding electrodes have poor corrosion resistance. In harsh soil environments such as damp, saline, or acidic soils, they are prone to oxidation and rust, leading to a gradual increase in grounding resistance. After prolonged use, they may lose their grounding function, requiring frequent maintenance and replacement, resulting in high maintenance costs and affecting the reliability of lightning protection. Second, the installation of grounding stakes in traditional grounding devices is difficult, often requiring manual hammering or mechanical pile driving. This is not only labor-intensive but also makes it difficult to ensure the grounding stakes are inserted vertically into the ground, resulting in insufficient contact between the grounding electrode and the soil, unstable grounding resistance, and affecting the efficiency of lightning current discharge.

[0004] Furthermore, the connections between the lightning receiving, conducting, and grounding components of existing lightning protection devices are mostly simple overlaps. Even the few connection structures made of new electrical contact precious metal materials cannot fully utilize their conductivity advantages due to unreasonable design, and still suffer from poor connection reliability, easy contact failure, and breakage, leading to obstruction of lightning current conduction and the generation of dangerous overvoltages. At the same time, some grounding devices lack effective auxiliary positioning and reset structures, making it difficult to control the insertion depth of the grounding stake, and it is prone to displacement after installation, further reducing the grounding effect. In addition, traditional conducting components mostly use rigid wires, which have poor flexibility and are prone to breakage during construction and use, and are difficult to adapt to the wiring requirements of different installation scenarios.

[0005] To address the aforementioned technical issues, there is an urgent need to develop a grounding device for a flexible graphite lightning protection grounding body that is corrosion-resistant, easy to install, reliably connected, and has a stable grounding effect, in order to overcome the shortcomings of existing technologies and meet actual lightning protection grounding requirements.

At the same time, the flexible graphite lightning protection wiring 331 has good flexibility and is not easy to break.

[0031] In some embodiments of the present invention, reference is made to... Figure 8 - Figure 11 As shown, the clamping component of the auxiliary pile driving part 500 is a pull-down clamp 530, and the reset guide component includes a foot pedal bracket 510 and a reset component 520. The foot pedal frame 510 is movably connected to the platform plate 110. The reset component 520 is used to reset the foot pedal frame 510. The pull-down clamp component 530 is slidably engaged with the foot pedal frame 510. The auxiliary pile pressing part 500 is also provided with a moving guide block 540. The moving guide block 540 is engaged with the pull-down clamp component 530 to drive the pull-down clamp component 530 to clamp the grounding plug 400.

[0032] Furthermore, the foot pedal frame 510 includes a U-shaped connecting plate frame 511, a pedal 512, a reinforcing rod 513, a support block 514, a guide post 515, a spring 516, and a limiting groove 517. The reinforcing rod 513 is fixedly welded to both ends of the U-shaped connecting plate frame 511. The pedal 512 is fixed in the middle of the U-shaped connecting plate frame 511. The reinforcing rod 513 is movably inserted into the socket 130. The support block 514 is fixedly welded to the upper end of the reinforcing rod 513. The guide post 515 is fixed inside the support block 514. The spring 516 is sleeved on the guide post 515. The limiting groove 517 is opened on the support block 514.

[0033] Furthermore, the reset component 520 includes a guide rod 521, a bolt stop 522, and a second spring 523. The guide rod 521 is fixed on the U-shaped connecting plate frame 511 and is movably inserted into the positioning hole 140. The bolt stop 522 is threadedly connected to the upper end of the guide rod 521. The second spring 523 is sleeved on the guide rod 521. The upper end of the second spring 523 abuts against the bolt stop 522, and the lower end abuts against the platform plate 110.

[0034] Furthermore, the pull-down clamp 530 includes a clamping half-ring 531, a rubber strip 532, a reinforcing end block 533, a pulley 534, a sleeve block 535, and a limiting protrusion 536. The rubber strip 532 is embedded in the inner side of the clamping half-ring 531. The reinforcing end block 533 is fixed to the end of the clamping half-ring 531. The pulley 534 is rotatably connected to the pre-set mounting groove at the end of the reinforcing end block 533. The sleeve block 535 is fixed to the bottom of the reinforcing end block 533 and sleeved on the guide post 515.

[0036] Through the auxiliary pile pressing part 500 foot pedal frame 510, pull-down clamp part 530 and other structures, the grounding plug 400 can be pressed in a labor-saving manner without manual hammering or large machinery, making the operation convenient; at the same time, the positioning collar 220 of the positioning sleeve 200 accurately guides the grounding plug 400, ensuring that the grounding plug 400 is inserted vertically into the ground, solving the problems of laborious installation and inaccurate positioning of traditional grounding plugs.

[0037] When the grounding stake 400 is inserted into the ground through the auxiliary pile driving part 500, the grounding stake 400 is first inserted from the upper end of the pile opening 120 of the support platform 100. After passing through the pile opening 120, it is inserted into the positioning ring 220 of the positioning sleeve 200 to ensure that the grounding stake 400 is perpendicular to the platform plate 110 and the cone head 430 is facing down.

[0038] Then, the operator steps on the pedal 512 of the foot pedal frame 510, causing the U-shaped connecting plate frame 511 to move downwards along with the reinforcing rod 513, the support block 514, and the pull-down clamp 530. At this time, the guide rod 521 slides downwards along the positioning hole 140, and the second spring 523 is compressed, storing the return force. When the pull-down clamp 530 moves downwards, the pulley 534 rolls along the inclined guide end 542 of the moving guide block 540. Under the guidance of the inclined surface, the two symmetrically arranged clamping half-rings 531 move closer to the middle, and the first spring 516 is compressed. The rubber strip 532 on the inner side of the clamping half-rings 531 fits tightly against the insulating outer post 410 of the grounding plug 400, achieving stable clamping of the grounding plug 400. Through the clamping force of the pull-down clamp 530 on the grounding plug 400, the grounding plug 400 moves downwards, and the cone head 430 is inserted into the ground until the grounding plug 400 reaches the preset burial depth. When pedal 512 is released, spring 523 returns to its natural state, causing the U-shaped connecting plate frame 511, reinforcing rod 513, and pull-down clamp 530 to return to their original position. At the same time, spring 516 returns to its natural state, causing the pull-down clamp 530 to open to both sides, releasing the clamp on the grounding plug 400, and preparing for the next pedaling action.
