Description

TECHNICAL FIELD

[0001] The utility model relates to a grounding device for lightning disaster prevention. BACKGROUND

[0002] The grounding device refers to the general term of the grounding electrode buried in the ground and the connecting wire between the grounding electrode and the equipment, which is used to realize the purpose of connecting the electrical system with the ground. The metal object directly contacting with the ground to realize the electrical connection is the grounding electrode. It can be an artificial grounding electrode or a natural grounding electrode. The grounding electrode can be endowed with certain electrical functions, such as system grounding, protective grounding or signal grounding.

[0003] In the patent file with the publication number CN215955503U, a grounding device for lightning disaster prevention is disclosed. The outer cylinder is in a cylindrical shape, and the bottom end of the outer cylinder is in a sharp cone shape. The sharp cone shape can facilitate the insertion of the outer cylinder into the soil. The bottom end of the outer cylinder is provided with a guide groove, which facilitates the extension of the elastic metal strip. The inner part of the outer cylinder is slidingly connected with a slide rod, which provides power for the elastic metal strip. The bottom end of the slide rod is fixedly connected with the elastic metal strip. When the slide rod moves downward, the elastic metal strip can pass through the inside of the guide groove and enter the soil. After the elastic metal strip is inserted into the soil, it can increase the contact area with the ground and play a role in gripping the ground, ensuring that the grounding device does not come off. The elastic metal strip is provided with a retention groove. After the elastic metal strip is deeply inserted into the soil, the retention groove will continuously accumulate soil, further increasing the gripping effect.

[0004] In the above-mentioned device, the elastic metal strip is inserted into the soil to increase the gripping effect. Although the insertion of the elastic metal strip into the ground can increase the gripping effect to a certain extent, when the grounding device is subjected to pulling force, the elastic metal strip will bear the pulling force, which may cause the metal strip to break or be pulled out under a large pulling force. Therefore, a new grounding device for lightning disaster prevention is proposed to optimize the above-mentioned prior art. TECHNICAL CONTENT
