Description
Technical field
The utility model relates to the line-to-ground equipment technical field of applying in circuit on power system work progress, particularly a kind of new type grounding device that is applicable to pan soil matter.
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, ensures electric industry operating personnel's safety.Line-to-ground line is made up of insulating rod, copper conductor and earth electrode, requires earth rod buried depth to be not less than 60 centimetres at " electric power safety working regulation " (power circuit part) (trying) 3.4.7.Existing line-to-ground line earth electrode is pin type, and head point point is taked when 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, and 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.
But northwest is much local at home, and affiliated area major part is massif area, and geology is hard, soil property thickness, is difficult to earth rod to wedge underground 60 centimetres.The earth rod surface light that adds current use is level and smooth, in construction and in the work such as overhauling, apply to install time, runs into mountain region, frozen soil layer is difficult under wedge, easily causes earth rod buried depth inadequate, and earth resistance can not meet code requirement.And in the time tearing earth rod open, because barred body buried depth is 60 centimetres of left and right, be difficult to extract, can not pull out out and can only lose.
Connect the difficult technical problem of torch in order to solve mounting or dismounting on massif soil layer, CN201120204840.1 discloses a kind of ground electrode of ground wire with screw-type lines, it is characterized in that it comprises earth electrode body and sleeve handle, earth electrode body mid portion is a round steel, one end of round steel is welded with spiral bit, the other end is welded with a nut, below nut, be welded with a block length square flat iron plate, there are respectively two circular holes that vary in size the both sides of band iron plate, sleeve handle is made up of handle round steel and sleeve, and two sections of round steel are symmetrically welded at the both sides of sleeve.Its weak point is: 1) in use, earth connection is not easy to be screwed into, even if effort is screwed into, the easy oblique cutting underground layer of earth connection, so just need to be screwed into longer earth connection, and more wastes time and energy in the time taking out, because in severe cold area, imbed after overlong time, earth connection freezes in soil layer, is more not easy to take out.2) can not accurately judge insertion depth.
Utility model content
The purpose of this utility model is to provide a kind of new type grounding device that is applicable to pan soil matter, and this device not only can accurately be controlled insertion depth, and can make earth connection vertically insert ground, and it is time saving and energy saving to insert, and convenient taking-up.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of new type grounding device that is applicable to pan soil matter, comprise earth connection and base, and the body of rod of described earth connection is twist drill rods, described base arranges twist drill rods guided rotation mechanism.
In described guided rotation mechanism, through hole is set, these through hole two ends arrange bearing, and the nut matching with twist drill rods is set in bearing.
Several tapered thorns are set under described base.
Described bearing is hermetically sealed bearing.
T shape turning handle is set on described twist drill rods.
The top of described twist drill rods arranges the terminal block with screw.
On described twist drill rods, graduation mark is set.
When use, base is put on the ground, operating personnel stands on base plate, twist drill rods is inserted to the nut in bearing, rotate earth connection, two nuts rotate earth connection all the time in the vertical direction, can easily very fast twist drill rods be inserted underground, and can ensure vertical insertion, time saving and energy saving; Several tapered thorns are set under described base, and the frictional force on increase and ground, prevents that base from rotating; Described bearing is hermetically sealed bearing, prevents that soil from entering bearing; T shape turning handle is set on described twist drill rods, rotates more laborsaving; The top of described twist drill rods arranges the terminal block with screw, makes easy-to-connect and firm; On described twist drill rods, graduation mark is set, the convenient twist drill rods insertion depth of controlling.Therefore, comprehensively above-mentioned, the utility model not only can accurately be controlled insertion depth, and can make earth connection vertically insert ground, and it is time saving and energy saving to insert, and convenient taking-up.
