[0014] The present invention provides a substation anti-drop-out grounding device, which has the following beneficial effects: (1) The present invention cooperates with an arc-pressing plate through a vertical shell, a battery pack, a ring frame, an electric telescopic rod, a hole cover, a circular plate, a hole frame, a double-hole rod, a horizontal support plate, a ground wire, a long plate and a slide rod. The horizontal support plate moves to the bottom of the cable, and the telescopic end of the electric telescopic rod drives the long plate to move downward, and the long plate drives the arc-pressing plate to move downward. During the downward movement of the long plate, the long plate drives the slide rod to move downward, and the slide rod slides downward in the slide hole of the hole frame. The arc-pressing plate contacts the cable, and the slide rod guides the arc-pressing plate, so that the arc-pressing plate and the horizontal support plate clamp the cable over a large area. The ground wire on the horizontal support plate conducts the electricity of the cable, thereby preventing the ground wire from falling off easily due to the small clamping area of ​​the arc-pressing plate and the horizontal support plate.

[0015] (2) The present invention sets up an anti-touching wire device so that the recessed block one, the square rod, the clamping block and the thick rod cooperate with the recessed block two. The thick rod is restricted by the recessed block two, and the thick rod rotates left in the recessed block two. The square rod rotates left under the thick rod. The square rod rotates left in the clamping block. The square rod drives the clamping block to rotate left, and the clamping block drives the ground wire to rotate left, so that the clamping block drives the ground wire to deviate to the left, so that maintenance personnel will not accidentally touch the ground wire when removing the equipment, thereby preventing maintenance personnel from accidentally touching the ground wire and causing personal injury.

[0016] (3) The present invention provides an anti-touch-wire device so that the sliding frame and the arc-shaped spring sheet cooperate with the connecting plate. Under the elastic force of the arc-shaped spring sheet, the arc-pressing plate quickly clamps the cable on the cross-supporting plate, thereby preventing the arc-pressing plate and the cross-supporting plate from clamping the cable too slowly, resulting in poor cable clamping effect.

[0017] (4) The present invention sets an anti-oxidation device so that the hole block, U-shaped rod, straight ring block and ring strip block cooperate with the sponge ring. When the sponge ring moves upward, the sponge ring contacts the hole frame. Under the action of the extrusion force, the sponge ring squeezes out lubricating oil to the surface of the sliding rod, thereby preventing the sliding rod surface from being easily oxidized and rusted, causing the equipment to jam.

[0018] (5) The present invention sets an anti-oxidation device so that the short column and the plate cooperate with the spring sheet. When the spring sheet moves upward, the spring sheet contacts the hole frame. Under the elastic force of the spring sheet, the hole frame will not over-extrude the sponge ring, thereby preventing the hole frame from over-extruding the sponge ring and causing the sponge ring to be easily damaged by extrusion.

The sliding rod 12 guides the arc pressing plate 13, so that the arc pressing plate 13 and the horizontal supporting plate 9 clamp the cable in a large area. The ground wire 10 on the horizontal supporting plate 9 leads the current of the cable, so as to avoid the grounding wire 10 from falling off easily due to the small clamping area of ​​the arc pressing plate 13 and the horizontal supporting plate 9 when the anti-falling grounding device is grounded in the substation.

The arc-shaped spring piece 147 in a compressed state quickly deforms and stretches. Under the elastic force of the arc-shaped spring piece 147, the sliding frame 146 slides downward on the vertical shell 1, allowing the arc pressing plate 13 to quickly clamp the cable on the horizontal supporting plate 9, so as to avoid the arc pressing plate 13 and the horizontal supporting plate 9 clamping the cable too slowly when the anti-falling grounding device is grounded in the substation, resulting in poor cable clamping effect.

[0026] Hole blocks 151 are fixed to the front and back sides of the sliding frame 146, and U-shaped rods 152 are fixed to the inner walls of the two hole blocks 151, and a straight ring block 153 is fixed to the outer wall of the U-shaped rod 152.

[0030] While the long plate 11 drives the slide bar 12 to move upward, the slide bar 12 drives the concave block 141 to move upward, the concave block 141 drives the slide frame 146 to move upward, the slide frame 146 drives the hole block 151 to move upward, the hole block 151 drives the U-shaped rod 152 to move upward, the U-shaped rod 152 drives the straight ring block 153 to move upward, the straight ring block 153 drives the ring strip block 154 to move upward, and the ring strip block 154 drives the sponge ring 155 to move upward. In the process of the sponge ring 155 moving upward, the sponge ring 155 contacts the hole frame 7, and under the action of the extrusion force, the sponge ring 155 squeezes out lubricating oil onto the surface of the slide bar 12 to prevent the surface of the slide bar 12 from being easily oxidized and rusted when the equipment is used for a long time, thereby avoiding the problem of equipment operation jamming caused by the surface of the slide bar 12 being easily oxidized and rusted during the long-term use of the anti-falling grounding device.

[0031] While the U-shaped rod 152 drives the straight ring block 153 to move upward, the straight ring block 153 drives the short column 156 to move upward, the short column 156 drives the plate 157 to move upward, and the plate 157 drives the spring sheet 158 ​​to move upward. In the process of the spring sheet 158 ​​moving upward, the spring sheet 158 ​​contacts the hole frame 7. Under the elastic force of the spring sheet 158, the hole frame 7 will not over-squeeze the sponge ring 155, thereby preventing the hole frame 7 from over-squeezing the sponge ring 155 when the equipment is in use, thereby avoiding the problem that the sponge ring 155 is easily squeezed and damaged due to the hole frame 7 over-squeezing the sponge ring 155 when the anti-falling grounding device is grounded in the substation.
