Embodiment
Below in conjunction with accompanying drawing, describe the embodiment of the installation of the utility model ground wire and checkout gear in detail.
With reference to Fig. 1 and Fig. 3, the ground wire that the utility model provides is installed and checkout gear, comprises mounting panel 1, casing 9,10, earthing rod 2, position inspection sleeve 3, return spring 4, butterfly mother 5, sensitive switch 6, sensitive switch bearing 7 and aerial plug-in unit 8.
Wherein casing comprises top cover 9 and drain pan 10, and top cover 9 is fastened on the upper end of drain pan 10, and drain pan 10 is fixedly mounted on mounting panel 1.
Earthing rod 2 vertical weldings are combined on mounting panel 1 and by top cover 9 upper ends and stretch out.Butterfly female 5 is threaded connection with earthing rod 2.
Position inspection sleeve 3 is sleeved on earthing rod 2.Inspection sleeve 3 lateral surface upper ends, position are processed with annular groove 11, and inspection sleeve 3 medial surface lower ends, position are processed with another annular groove 12, and position inspection sleeve 3 is provided with base frame 13.
Return spring 4 one end are against on base frame 13, and return spring 4 other ends are against the upper end of another annular groove 12, position inspection sleeve 3 and female 5 synchronization actions of butterfly.
Sensitive switch 6 is arranged on sensitive switch bearing 7, and sensitive switch bearing 7 is arranged on drain pan 10, and sensitive switch bearing 7 is processed with limiting plate 14 vertically downward, and the position of limiting plate 14 bottom surfaces flushes with the position of tangent plane under metal wheel after sensitive switch 6 actions.The metal wheel shell fragment of sensitive switch 6 and the upper surface of base frame 13 cooperatively interact.
Aerial plug-in unit 8 is arranged on the side of drain pan 10.Aerial plug-in unit 8 adopts 2 core plug-in units, and two tie point is connected with a pair of normal opened contact electricity of sensitive switch 6 respectively.
The utility model ground wire is installed with the course of work of checkout gear as follows:
The utility model ground wire is installed with checkout gear and is fixedly mounted on the electric equipments such as high-tension switch cabinet.
With reference to Fig. 2 and Fig. 4, when artificial installing ground wire, be rotated counterclockwise butterfly female 5 and depart from earthing rod 2 to butterfly female 5, by temporary ground wire installing inspection sleeve 3 tops that put in place, then use butterfly mother 5 by earth connection and position inspection sleeve 3 close contacts, female 5 o'clock of butterfly turns clockwise, position inspection sleeve 3 moves down simultaneously, rotation butterfly is observed an annular groove 11 for position inspection sleeve 3 at female 5 o'clock, when the upper edge of annular groove 11 is with top cover 9 during at same plane, and the ground wire dead ground of installing.Now the shell fragment of sensitive switch 6 is along with the base frame 13 of position inspection sleeve 3 moves down and moves down, for external equipment provides ground wire installing status signal.
With reference to Fig. 1 and Fig. 3, when removing ground wire, be rotated counterclockwise butterfly female 5 and depart from earthing rod 2 to butterfly female 5, temporary ground wire is removed.Be rotated counterclockwise butterfly at female 5 o'clock, butterfly mother 5 moves up along the screw thread of earthing rod 2, and position inspection sleeve 3, under the elastic force effect of return spring 4, moves up simultaneously.Now on the base frame 13 of the shell fragment of sensitive switch 6 along with position inspection sleeve 3, move and on move, normal opened contact is closed, for external equipment provides ground wire, removes status signal.When the inspection base frame 13 of sleeve 3 in position is when the limiting plate 14 of sensitive switch bearing 7 contacts, a position inspection sleeve 3 stops moving up, anti-stop bit inspection sleeve 3 bad sensitive switch of bit loss 6.
