Abstract
The utility model provides a rapid-construction screw-type grounding electrode. The grounding electrode comprises a screw rod. One end of the screw rod is provided with a conical head and the other end is provided with a cylinder bench. A lateral portion of the cylinder bench is provided with a through hole with an internal screw thread. A bolt is installed in the through hole. A top of the cylinder bench is provided with a raised prismatic bench. A temporary grounding device can not be fixed underground well and it is difficult to remove the device when the place is with complex soil. By using the grounding electrode of the utility model, the above problems are solved. The grounding electrode can be used repeatedly. It is convenient to screw in and pull out the grounding electrode. Phenomena that there is no grounding electrode bending, a depth is not enough and so on are avoided. Safety production of construction personnel is guaranteed and there is no accident. A grounding effect is good. Usage is convenient and reliable.
Description
Technical field
The utility model relates to electric power, building grounding system earth electrode, relates in particular to the spiral earth electrode of a kind of rapid construction.
Background technology
Line-to-ground line is in line construction process, to be installed in dead line side, and the equipment that prevents is sent a telegram here suddenly and caused workmen's injury.Line-to-ground line is comprised of insulating rod, copper conductor and earth electrode, and during use, earth electrode will enter underground at least 60cm.Existing line-to-ground line earth electrode is pin type, and head point point, takes during use to pound into underground mode with hammer or stone.Copper conductor is wanted crimping, forbids carrying out ground connection or short circuit by the way being wound around.Line-to-ground line exists earth electrode be not easy to insert underground and hold flexible shortcoming in work progress, causes potential Danger Electric shock risk very high, has had a strong impact on construction safety.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provides a kind of rapid construction spiral earth electrode, cost-effective rapid construction earth electrode.
The technical scheme of this real utility model is achieved in that
The spiral earth electrode of rapid construction, comprises screw rod, it is characterized in that: one end of described screw rod is provided with conical head, the other end is provided with cylinder table, this cylinder table sidepiece is provided with tapped through hole, and bolt is installed in through hole, and the top of described cylinder table is provided with protruding terrace with edge.
Described screw rod is metal spiral bar, and its outer wrap has electrically conductive graphite layer.
The cross section of described terrace with edge is outer cubic angle or outer six corner structures.
Beneficial effect:
The utility model has solved temporary earthing device, and to run into the place of soil property complexity bad lower and take out difficult problem regularly.Earth electrode can be reused; Be screwed into, to extract earth electrode very convenient, the no ground extremely crooked and phenomenon such as the degree of depth not, has guaranteed workmen's safety in production accident free.Earthing effect is good; Easy to use and reliable, facility.
