Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to a grounding rod. Background Art

[0002] The grounding rod, also known as the grounding needle or grounding electrode, is an important component of electrical equipment. It is mainly used to improve the internal conductivity of the grounding conductor and reduce the external soil resistivity of the grounding conductor. It plays a vital role in electrical safety and can effectively conduct and release lightning current to protect equipment and personal safety.

[0003] The existing grounding rods need to rely on electric pickaxes or construction workers to manually hammer the top of the grounding rod with a hammer to connect the grounding rod into the ground. The grounding rod body needs to be supported, which is inconvenient to operate and has certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to provide a grounding rod in view of the above-mentioned technical problems, and to set a limit assembly. When installing the grounding rod, there is no need for construction workers to support the grounding rod body, thus avoiding operational inconvenience and existing safety hazards.

[0006] In the present technical solution, when in use, the operator first fixes the support plate to the ground, or fixes the support plate by stepping on the support plate, and then inserts the grounding rod body through the bundle sleeve to contact the ground, and then uses a hammer, electric pick or other tools to hammer or drill the grounding rod body into the ground to fix it. There is no need for construction workers to support the grounding rod body, avoiding inconvenience in operation and potential safety hazards.

The bottom of the support block abuts against the support plate, and the top abuts against the upper cover. The upper cover is sleeved on the upper port of the positioning sleeve. A supporting component is connected between the support block and the inner wall of the positioning sleeve, and the supporting component can push the support block and the ground rod body passing through the positioning sleeve to slide and abut.

[0008] In the above technical solution, further, the abutment block includes a first plate and a second plate, the second plate is arranged in a fit on the side of the first plate facing the grounding rod body, the first plate and the second plate are correspondingly provided with placement grooves, the placement grooves are arranged in an array along the vertical direction, balls are arranged to roll in the placement grooves, and the ball part is exposed from the second plate and can be slidably connected to the grounding rod body.

[0009] In the present technical solution, the first plate and the second plate are both annular plates, and the two can be connected by threads or welding to limit the rolling of the ball in the placement groove. The support component pushes the abutment block to move in the direction of the central axis of the positioning sleeve until it contacts the grounding rod body passing through the positioning sleeve, so that grounding rods of different specifications can be limited. At the same time, the abutment block is limited by sliding through the ball and the grounding rod, which can avoid wear on the surface of the grounding rod when the abutment block limits the grounding rod.

[0010] In the above technical solution, further, the supporting component includes an airbag arranged between the first plate and the restraining sleeve, the airbag is connected to an air nozzle, the air nozzle is arranged on the top of the upper cover, and the airbag can push the abutment block to move along the radial direction of the restraining sleeve.

[0011] In the present technical solution, an external gas source is used to pass gas into an airbag arranged between the first plate and the positioning sleeve through a gas nozzle. The airbag expands, pushing a number of circumferentially arranged abutment blocks to move along the radial direction of the positioning sleeve, thereby abutting and limiting the grounding rod body coaxially passing through the positioning sleeve.

[0012] In the above technical solution, further, the supporting component is a first spring, the first springs are arranged in an array along the length direction of the second plate, one end of the first spring is connected to the outer wall of the first plate, and the other end is connected to the inner wall of the positioning sleeve.

[0017] In this technical solution, the inner threaded tube and the outer surface of the grounding rod body are provided with corresponding outer threads, the inner threaded tube is perpendicular to the support plate, and the support plate is parallel to the ground, ensuring that the grounding rod body passing through the inner threaded tube is vertically drilled into the ground to complete the installation.

[0018] The beneficial effects of the utility model are:

[0019] 1. When in use, the operator first fixes the support plate to the ground, or fixes the support plate by stepping on the support plate, then inserts the grounding rod body through the tie sleeve and contacts the ground, and then uses a hammer, electric pick or other tools to hammer or drill the grounding rod body into the ground to fix it. There is no need for construction workers to support the grounding rod body, thus avoiding inconvenience in operation and potential safety hazards;

[0020] 2. The fixed support plate is parallel to the ground, and the tie sleeve is perpendicular to the support plate, that is, perpendicular to the ground. The pressing piece in the tie sleeve can make the ground rod body pass through the ground in a state perpendicular to the ground. The ground rod body vertically set into the ground can distribute the current more evenly, effectively reduce the grounding resistance, and improve the grounding efficiency;

[0021] 3. Both the first plate and the second plate are annular plates, and the two can be connected by threads or welding to limit the rolling of the ball in the placement groove. The support member pushes the abutment block to move toward the central axis direction of the positioning sleeve until it contacts the grounding rod body passing through the positioning sleeve, so that grounding rods of different specifications can be limited. At the same time, the abutment block is limited by sliding through the ball and the grounding rod, which can avoid wear on the surface of the grounding rod when the abutment block limits the grounding rod.
