A grounding device for intelligent grounding wire based on power engineering

Abstract

The invention discloses a grounding device for an intelligent grounding wire based on electric power engineering, belongs to the field of electric power engineering, and comprises a clamping block. An insulating rod is arranged below the clamping block, and a progressive groove is opened on the inner side wall of the clamping block. The clamping assembly comprises a backing plate installed on the top of the insulating rod. Through the arrangement of the clamping assembly and the insulating rod, a first screw rod is rotated to drive a lifting rod to rise, and the lifting rod drives the backing plate to rise. When the backing plate rises, it cooperates with the clamping block to clamp and fix the wire in the upper and lower directions. When the backing plate rises, it drives a toothed bar to slide in the progressive groove. As the toothed bar continues to rise, the toothed bar slides on the trapezoidal surface of the progressive groove, and then the toothed bar moves toward the inside of the cavity to drive a first toothed disc and a second toothed disc to rotate. The rotation of the second toothed disc drives push rods on both sides to move relatively. When the push rod moves relatively, it drives the clamping plate to clamp the left and right sides of the wire, thereby completing the clamping of the wire on four sides, thereby avoiding safety hazards caused by accidental falling of the wire.

The rotation of the second gear plate drives the push rods on both sides to move relative to each other. When the push rods move relative to each other, they drive the clamping plate to clamp the left and right sides of the wire, thereby completing the clamping of the wire on all four sides, thereby avoiding accidental falling of the wire and causing safety hazards.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 6 The present embodiment provides a grounding device for an intelligent grounding wire based on electric power engineering, comprising a card block 2. An insulating rod 1 is arranged below the card block 2, and a progressive groove is provided on the inner side wall of the card block 2;

[0027] The insulating rod 1 includes a lifting cylinder 101 installed at the bottom of the block 2, and first guide grooves are provided on both sides of the inner wall of the lifting cylinder 101. A lifting rod 102 is slidably connected inside the first guide groove. A rotating rod 103 is rotatably connected to the bottom of the lifting cylinder 101. A first screw rod 104 is fixedly connected to the top of the rotating rod 103. The other end of the first screw rod 104 passes through the bottom of the lifting cylinder 101 and is threadedly connected to the inside of the lifting rod 102.

[0029] Among them, rotating the rotating rod 103 drives the first screw rod 104 to rotate, and the rotation of the first screw rod 104 drives the lifting rod 102 to rise, and the lifting rod 102 drives the support plate 301 to rise. When the support plate 301 rises, it cooperates with the clamping block 2 to clamp and fix the wire in the upper and lower directions. When the support plate 301 rises, it drives the gear rod 306 to slide in the progressive groove. As the gear rod 306 continues to rise, the gear rod 306 slides on the trapezoidal surface of the progressive groove, and then the gear rod 306 moves toward the inside of the cavity to drive the first toothed disc 302 and the second toothed disc 303 to rotate. The rotation of the second toothed disc 303 drives the push rods 304 on both sides to move relative to each other. When the push rod 304 moves relative to each other, it drives the clamping plate 305 to clamp the left and right sides of the wire, thereby completing the clamping of the wire on all four sides.

[0030] Specifically, Figure 1 and Figure 6 As shown, a grounding wire body 4 is also provided on the outside of the clamping block 2 , and a plug post 5 is provided at the other end of the grounding wire body 4 .

[0031] The plug post 5 is inserted into the ground, and the ground wire body 4 is connected to transmit electricity to the ground to ensure the safety of the construction workers.

[0032] Specifically, Figure 1 As shown, an arc-shaped groove is provided on the upper surface of the abutment plate 301, and anti-slip strips 6 are fixedly connected to both sides of the upper surface of the arc-shaped groove.

[0033] The anti-slip strip 6 is provided to strengthen the friction between the abutment plate 301 and the wire, thereby preventing the wire from sliding back and forth when clamped.

[0034] Specifically, Figure 4 As shown, the plug column 5 includes an insertion rod 51, a top plate is provided on the top of the insertion rod 51, a contraction cavity is opened inside the insertion rod 51, second guide grooves are opened on both sides of the inner wall of the contraction cavity, a counter cone 53 is slidably connected inside the second guide groove, a second screw rod 52 is rotatably connected to the inner bottom wall of the contraction cavity, the top of the second screw rod 52 is penetrated through the top of the top plate and the surface is threadedly connected to the counter cone 53, anti-pull rods 54 are inserted on both sides of the middle of the contraction cavity, a second baffle 55 is fixedly connected to one side of the surface of the anti-pull rod 54, a second spring 56 is sleeved on the surface of the anti-pull rod 54, and the two ends of the second spring 56 are respectively connected to one side of the second baffle 55 and the inside of the cavity.

[0035] Among them, when the insertion rod 51 is inserted into the ground, the second screw rod 52 is rotated to drive the cone 53 to move downward, and the cone 53 moves downward to push the anti-pull rods 54 on both sides to move to the outside of the insertion rod 51 and insert into the ground, thereby improving the anti-pullout ability of the column 5, so that the column 5 is more firmly inserted.

[0036] Specifically, Figure 2 As shown, a through hole is formed at the bottom of the block 2, and the top of the lifting rod 102 passes through the inside of the through hole.

[0037] Specifically, Figure 1 As shown, the interior of the progressive groove is trapezoidal, and one side of the inner wall of the progressive groove contacts the end of one end of the gear rod 306 .

[0038] Among them, since the inside of the progressive groove is trapezoidal, the gear rod 306 becomes shallower as the depth of the progressive groove gradually decreases, thereby pushing the gear rod 306 to move.

[0039] Specifically, Figure 6 As shown, a plurality of reinforcing nails 7 are connected around the bottom of the top plate, and the end of one end of the anti-pullout rod 54 contacts the surface of the abutment cone 53.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
