Abstract
本实用新型涉及一种螺旋式接地棒。其特点是，包括一根圆钢(3)，该圆钢(3)的一端为圆锥状，在该圆钢(3)表面设有螺纹丝扣，而在该圆钢(3)的另一端固定有一连接板(2)，在该连接板(2)上开有两个通孔，另外在该连接板(2)旁的圆钢(3)上固定有一与圆钢(3)垂直的手柄(1)。本实用新型的有益效果是，第一避免了普通接地棒接触面积小，接地电阻大的问题，增大了接地棒与大地的接地面积，并且容易实现手工拆装。第二有效降低了接地棒接地电阻，使接地电阻下降约26％，避免了电压、泄后电流等对施工工作人员造成损害。并且工作效率也明显提高，从而缩短了停电时间，接地棒还可以重复使用。
The utility model relates to a spiral ground rod. It is characterized in that it includes a round steel (3), one end of the round steel (3) is conical, a screw thread is provided on the surface of the round steel (3), and the other end of the round steel (3) A connecting plate (2) is fixed, two through holes are opened on the connecting plate (2), and a handle perpendicular to the round steel (3) is fixed on the round steel (3) next to the connecting plate (2). (1). The beneficial effects of the utility model are: firstly, the problems of small contact area and large grounding resistance of ordinary grounding rods are avoided, the grounding area between the grounding rod and the earth is increased, and manual disassembly and assembly are easy to realize. The second is to effectively reduce the grounding resistance of the grounding rod, which reduces the grounding resistance by about 26%, and avoids damage to construction workers caused by voltage and leakage current. And the work efficiency is also significantly improved, thereby shortening the power outage time, and the grounding rod can be reused.
Description
Technical field
The utility model relates to a kind of spiral earth rod.
Background technology
Use earth rod to be at power construction, an important safety measure of doing before the work such as to overhaul, apply to install, when using the temporary grounding rod, require the earth rod buried depth to be not less than 60 centimetres at " electric power safety working regulation " (power circuit part) (trying) 3.4.7.But the northwest is much local at home, and affiliated area major part is the massif area, and geology is hard, the soil property thickness.Be difficult to earth rod is wedged underground 60 centimetres.
The earth rod surface light that adds present use is level and smooth, in construction with when overhauling, applying to install etc. in the work, runs into the mountain region, frozen soil layer is difficult under the wedge, easily causes the earth rod buried depth inadequate, and earth resistance can not satisfy the rules requirement.And when tearing earth rod open, because the barred body buried depth about 60 centimetres, is difficult to extract, can pull out out and can only lose.Connect the difficult technical problem of torch in order to solve in the mounting or dismounting of massif soil layer.
The utility model content
The purpose of this utility model provides a kind of spiral earth rod, can be implemented in mountain region, clay, tundra earth rod is installed smoothly.
A kind of spiral earth rod, its special feature is: comprise a round steel, one end of this round steel is coniform, be provided with screw thread on this round steel surface, and be fixed with a plate at the other end of this round steel, have two through holes at this connecting plate, be fixed with a handle vertical with round steel at the other round steel of this connecting plate in addition.
Wherein connecting plate and handle all are welded on the round steel.
Wherein on the other round steel of connecting plate, also be provided with the buried depth sign, thereby be convenient to identify burying depth.
Wherein the cross-sectional area of round steel is that 20 square millimeters of length are 80 centimetres, and the depth of thread on round steel surface is 2.5 millimeters.
The beneficial effects of the utility model are, first has avoided common earth rod contact area little, the problem that earth resistance is large has increased the contact area (existing earth rod contact area increases about 1/3rd) of earth rod and the earth, and has realized easily manual dismounting.Second effectively reduces the earth rod earth resistance, and it is about 26% that earth resistance is descended, and has avoided voltage, has let out after-current etc. the construction working personnel are caused damage.And operating efficiency also obviously improves, thereby has shortened interruption duration, and earth rod can also be reused.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of spiral earth rod, comprise a round steel 3, one end of this round steel 3 is coniform, be carved with screw thread on these round steel 3 surfaces, and be fixed with a plate 2 at the other end of this round steel 3, thereby having two through holes at this connecting plate 2 can be connected with earth connection by screw, is fixed with a handle 1 vertical with round steel 3 at this connecting plate 2 other round steel 3 in addition.
Wherein connecting plate 2 and handle 1 all are welded on the round steel 3, also are carved with the buried depth sign on the round steel 3 on connecting plate 2 sides, thereby are convenient to identify burying depth.Through probationary certificate, the cross-sectional area of the round steel 3 that the utility model adopts is that 20 square millimeters of length are 80 centimetres, and the depth of thread on round steel 3 surfaces is 2.5 millimeters, and result of use is better.
