Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
As depicted in figs. 1 and 2, the present invention provides a kind of soft graphite grounding bodies for preventing fluid scouring, including inner core
Layer 1 and clad 2, inner sandwich layer 1 are more soft graphite lines, are coated with the first conductive adhesive layer on the outer wall of more soft graphite lines
3, wherein the first conductive adhesive layer 3 is preferably but is not limited to graphene conductive glue, has using graphene conductive glue and preferably lead
Electrically, more soft graphite lines are arranged closely in clad 2, form the conductor group for directly contacting with soil, it is ensured that
Can safe diffusing thunder energy make its leak into the earth.Specific more soft graphite lines can linear array or circular array point
Cloth, and the soft graphite line in the outside of inner sandwich layer 1 is close to the inner wall of clad 2 makes the shape of entire soft graphite grounding body can be with
Be designed as according to the specific installation situation of grounding body it is round or rectangular, convenient for being carried out according to different topographic features to grounding body
It is laid with.
As described above, clad 2 is the electric conductor for being coated on 1 outside of inner sandwich layer, specific clad 2 can be conductive modeling
The bed of material or conductive rubber layer, since existing soft graphite grounding body is mainly the tack according to graphite, after graphite expansion,
It is pressed into paper, is twisted into graphite line after cutting, is then woven into soft graphite grounding body, it is special if applied in the place for having fluid
It is not on rivers,lakes and seas side, for a long time by fluid scouring, graphite can be washed away slowly, lose ground connection electric conductivity, therefore benefit
The inside is coated on by conductive plastics or conductive rubber with graphite, it is possible to prevente effectively from fluid directly contacts inner core when flowing through grounding body
Graphite in layer 1 on graphite line, and then prevent fluid from washing away removing to graphite grounding body.Inner sandwich layer 1 and clad 2 it
Between be additionally provided with skeleton 4 (with reference to Fig. 3) for increasing grounding body intensity, cotton thread or glass or carbon fiber or each can be selected in skeleton 4
