Problems solved by technology

The length of this grounding device cannot be changed, and it is needle-shaped. The locking mechanism used is more suitable for relatively hard soil conditions. It does not work well in loose soil, and it needs to be nailed deeper into the ground under special conditions. At this time, the length of the grounding device cannot be changed
[0005] The above two inventions have better effects when used in general or relatively hard soil conditions, but the effect is obviously not good enough in loose soil areas
And when we use the existing grounding nails in normal work, the effect is better when the soil is normal or hard, but when it comes to areas with loose soil, the effect is greatly reduced. The effect is not good, and it is inconvenient to use when facing different soil conditions and need to increase or decrease the depth of burial in the ground. Because the grounding nails cannot change the length, it is necessary to bring various types of grounding nails, which brings a lot of troubles for construction and maintenance in loose soil areas. Inconvenience and safety hazard

Abstract

The invention discloses a grounding nail, which relates to the field of electric power tools. The grounding nail comprises a ground drilling guide head, a foundation rod detachably connected with theground drilling guide head, and a striking device detachably connected with the foundation rod, wherein the ground drilling guide head, the foundation rod and the striking device are connected in sequence. The grounding nail also comprises a lengthening pipe arranged between the foundation rod and the striking device. The lower end of the lengthening pipe is detachably connected with the foundation rod, and the upper end of the lengthening pipe is detachably connected with the striking device; water through holes are formed in the lengthening pipe and the foundation rod, so that water passingresistance reduction can be realized when the conductive resistance cannot meet the requirement; and a blade arranged on the drilling guide head not only can guide, but also can increase the groundingarea. The grounding nail is not prone to deviating when the nail is nailed into loose soil, and the length can be changed, so that the nail is suitable for being used in the loose soil.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a ground nail. Background technique [0002] With the development of my country's economy, my country's high-voltage transmission network is also spread all over the country. In order to ensure the safety of power supply, the maintenance of transmission lines is very important. High-voltage grounding devices will be used in the maintenance of high-voltage lines. It is an important tool to ensure the safety of staff when there is an unexpected voltage on the equipment and lines. When the power failure is overhauling the transmission line, in order to prevent the danger of electrostatic induction electric shock or false closing of the nearby charged body, it is necessary to insert the grounding nail below the ground. And the transmission line is connected by multi-strand grounding copper stranded wires to form a grounding system with good grounding performance to ensure the safety of op...
