Description

Technical Field

[0001] The utility model belongs to the technical field of lightning rods, in particular to a device for reducing grounding resistance of a lightning rod used for geological drilling. Background Art

[0002] During geological drilling construction, since it is necessary to carry out engineering construction for a long time in sparsely populated and high-altitude areas, lightning strikes are very likely to occur in thunderstorms and severe convective weather. Although various types of geological drilling equipment are equipped with lightning rods and their grounding wires, due to the long-term use of cables, they have been exposed to high temperatures, exposure to the sun, low temperatures, freezing and other environments, and various situations such as cable contact, resistance value, cable breakage, and loose connection with lightning rods may occur. At the same time, the reduction in ground soil moisture content will also cause significant changes in wire resistance. Once the above problems occur, safety accidents are very likely to occur in thunderstorms and severe convective weather. The current solution to the reduction in ground soil moisture content is to reduce the grounding resistance by manually spraying sodium chloride solution. This operation method has the following problems: First, the effect of manual spraying is uneven, and it cannot be guaranteed that the grounding resistance can be effectively reduced; second, the size of the grounding resistance cannot be detected in real time, which is prone to safety hazards.

The output shaft of the motor 7 drives the rotating ring 2 and the spray pipe 6 to rotate, and the sodium chloride solution is evenly sprayed around the grounding nail 5.

[0045] The end of the nozzle 6 near the rotating ring 2 is fixed with a hinge plate 1 604, the rotating ring 2 is fixed with a hinge plate 201, the hinge plate 201 is fixed with a hinge shaft, the axis of the hinge shaft is perpendicular to the axis of the rotating ring 2, and the hinge plate 1 604 is hinged to the hinge plate 2 201 through the hinge shaft. The end of the nozzle 6 away from the hinge plate 1 604 is fixed with a hook 1 603, the rotating ring 2 is fixed with a vertical plate 202 perpendicular to the upper end surface of the rotating ring 2, the upper end of the vertical plate 202 is fixed with a hook 203, the height of the hook 203 is higher than the height of the hinge shaft; the hook 203 is connected to the hook 1 603 through a rope 8. Loosening the rope 8 adjusts the angle between the axis of the nozzle 6 and the axis of the rotating ring 2, thereby adjusting the spraying range of the sodium chloride solution, which is suitable for different working scenes.

[0046] A connecting pipe 602 is provided at one end of the nozzle 6 near the rotating ring 2, and the connecting pipe 602 is connected to the nozzle 6;
