Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in figures 1 to 6; the stake of a kind of built-in type earth connection of the utility model; comprise over cap 1, pre-buried ground connection spool, earthing clamp 3, branch's ground wire borer 7; described earthing clamp 3 is fixed on the inside of pre-buried ground connection spool; described branch ground wire borer 7 is connected with branch's ground spool 6 of pre-buried ground connection spool lower end; described over cap 1 covers the upper end of pre-buried ground connection spool, is connected with the draw-in groove 4-1 of pre-buried ground connection spool upper end by the bayonet lock axle 1-3 of over cap lower end.
Described over cap 1 comprises top cover 1-1, block pin seat 1-2, bayonet lock axle 1-3, and block pin seat 1-2 is fixed on the bottom of top cover 1-1, and bayonet lock axle 1-3 is fixed on the both sides of block pin seat 1-2.
Described pre-buried ground connection spool comprises bracket 2, supervisor 4, branched pipe 6, bracket 2 is fixed on the upper end of supervisor, the upper surface of bracket and the upper end surface of supervisor 4 are in same plane, branched pipe 6 is fixed on the bottom of supervisor 4, branched pipe 6 is interconnected with supervisor 4, and the both sides at supervisor 4 top are provided with draw-in groove 4-1.
Bracket 2 is socketed in the outside of supervisor 4 upper end, and the upper end surface of upper surface and supervisor 4, in same plane, connects over cap for holder.
Branched pipe 6 bottom supervisor 4 is certain inclination angle with supervisor's 4 bottom surfaces, and radiation outwards opens, and is inserted into each branched pipe 6 when branch's marchantia pricker 7 is installed from supervisor 4 inside, and from the embedding underground, lower end of branched pipe 6.Because branched pipe 6 and supervisor's 4 inclination radiations outwards open, therefore the upper end of branch's ground wire borer 7 fully can contact connection with branched pipe 6, and forms radioactive ground network in underground, effectively can ensure the through-current capability of ground wire.
Described earthing clamp 3 comprises binding clip 3-1, wire clamp seat 3-2, and binding clip 3-1 is fixed on the upper end of wire clamp seat 3-2, and wire clamp seat 3-2 is fixedly connected with the inwall of supervisor 4.
Be threaded outside binding clip 3-1, be evenly equipped with four clamping slots, can the metal bar connecting earth connection be directly inserted in binding clip 3-1, also in outside, binding clip 3-1 can be locked by nut, increase contact area and the tightness of binding clip 3-1 and metal bar.
A using method for built-in type earth connection stake, concrete grammar step is as follows:
1) reserve the pre-buried hole burying earth connection stake underground in bottom surface, pre-buried ground connection spool is placed in pre-buried hole;
2) adjust the pre-buried position of ground connection spool in pre-buried hole, make the upper surface of pre-buried ground connection spool concordant with ground;
3) by joints cement, pre-buried ground connection spool is fixed in pre-buried hole;
4) inside of branch's ground wire borer 7 from pre-buried ground connection spool is penetrated branched pipe 6, and branch's ground wire borer 7 is hammered into the soil of branched pipe 6 lower end from branched pipe 6;
If sandstone soil property, resistance reducing agent can be set in the surrounding of built-in type earth connection stake, in order to reduce resistance, increase the through-current capability of protection ground wire.
5) not used time, over cap 1 covered the upper end of pre-buried ground connection spool and by rotation, bayonet lock axle 1-3 and draw-in groove 4-1 locked, can prevent foreign material from falling in the supervisor 4 of pre-buried ground connection spool.During earth connection, the metal bar being connected to earth connection is inserted in earthing clamp 3.The external diameter of metal bar should close with the diameter compatible of binding clip 3, ensures that metal bar fully contacts with binding clip 3.
