Description

Technical Field

[0001] The invention relates to the technical field of grounding wires, and in particular to a grounding wire that is easy to hang. Background Art

[0002] The grounding wire is an essential safety tool for daily power operation and maintenance, emergency repair work and power grid construction. It is mainly used as a temporary grounding device to prevent sudden power supply to equipment and lines, eliminate induced voltage, and discharge residual charge. The currently used power portable short-circuit grounding wire is mainly composed of an insulating operating rod, a conductor clamp, a grounding copper wire, etc. When in use, the operator clamps the conductor clamp on the conductor through the insulating operating rod, so that the conductor is connected to the grounding rod on the ground through the conductor clamp and the grounding copper wire to form a ground.

[0003] The patent with announcement number CN112467405B discloses a high-voltage grounding wire device with anti-unhooking. By setting an anti-unhooking component, the cable enters from the upper part of the conductor end wire clamp opening and comes out from the lower part. After clamping, the cable is located in the upper part of the conductor end wire clamp and will not come out, which can effectively ensure that the cable does not detach from the conductor end. Its specification details its working process and principle, which is roughly as follows: hanging, moving the U-shaped bracket to make the cable contact with the upper part of the connecting rod and drive the upper part of the connecting rod into the U-shaped bracket, then the cable enters the U-shaped bracket, then the U-shaped bracket is moved and the connecting rod is reset through the cable, then the insulating rod is rotated so that the clamping plate clamps the cable; removing, rotating the insulating rod so that the cable is no longer clamped by the clamping plate, and then moving the U-shaped bracket so that the cable goes out from the lower part of the connecting rod. The insulating rod is connected to the U-shaped bracket by a screw, and it takes a certain amount of time to rotate the insulating rod. It can be seen that the operation steps when hanging and removing are cumbersome, the operation is difficult, and the efficiency is low.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, it includes an insulating operating rod 1 and a clamping block 4, and also includes: a grounding rod 3 and an elastic telescopic component;

[0031] The top of the insulating operating rod 1 is fixedly connected to a grounding block 2, the top of the grounding block 2 is fixedly connected to the bottom of the grounding rod 3, the top of the grounding rod 3 is bent downward to form a hook section 301, two grounding rods 3 are arranged at intervals, the two grounding rods 3 are arranged in a centrally symmetrical manner with the central axis of the insulating operating rod 1 as the center, and the center lines of the two hook sections 301 are located on the same straight line;

[0032] The elastic telescopic component is installed on the grounding block 2 , the clamping block 4 is arranged between the two grounding rods 3 , the elastic telescopic component is located below the clamping block 4 , and the elastic telescopic component can drive the clamping block 4 to enter the hook section 301 .

[0033] Specifically, the insulating operating rod 1 can be bonded or threaded with the grounding block 2; the grounding rod 3 can be threaded, integrally formed or welded with the grounding block 2. The insulating operating rod 1 can be made of, but not limited to, fiberglass, for example, epoxy resin or other insulating materials.

[0034] Before hanging, connect one end of the grounding copper wire 14 to the earth, and then electrically connect the other end of the grounding copper wire 14 to the grounding block 2. Figure 3 and Figure 4 For example, firstly, the clamp block 4 is lowered so that it withdraws from the hook section 301, and the conductor 13 is placed in the interval between the two grounding rods 3, and the conductor 13 is lower than the end of the hook section 301. At this time, the insulating operating rod 1 can be rotated so that the hook section 301 is aligned with the conductor 13, and then the elastic telescopic component drives the clamp block 4 to rise and enter the hook section 301, forming Figure 1 and Figure 2 In the form shown, the conductor 13 is clamped by the clamp block 4 and the grounding rod 3. To remove the clamp block 4, the clamp block 4 is lowered so that it withdraws from the hook section 301, the grounding rod 3 is moved upward and the conductor 13 is lower than the end of the hook section 301. At this time, the insulating operating rod 1 can be rotated so that the conductor 13 is located between the two grounding rods 3, and the present invention can be removed.

[0035] like Figure 2 and 4 As shown, the elastic telescopic component includes a slide rod 5 and a tension spring 6. The slide rod 5 is coaxially arranged with the insulating operating rod 1. The top end of the slide rod 5 is fixedly connected to the clamping block 4. The bottom end of the slide rod 5 slides through the grounding block 2 and extends into the central axis hole of the insulating operating rod 1. The bottom end of the slide rod 5 is fixed with a limit plate 7. The tension spring 6 is sleeved on the slide rod 5, and the top end of the tension spring 6 is fixedly connected to the bottom surface of the grounding block 2, and the bottom end of the tension spring 6 is fixedly connected to the top surface of the limit plate 7.

[0036] Specifically, the slide bar 5 and the clamp block 4 can be bonded, welded or threaded. The limit plate 7 can be bonded, welded or threaded to the slide bar 5. The top of the tension spring 6 can be welded, bonded or otherwise fixedly connected to the ground block 2; the bottom of the tension spring 6 can be welded, bonded or otherwise fixedly connected to the limit plate 7. The tension spring 6 provides an upward pulling force to the limit plate 7, so that the limit plate 7 can rise. When the limit plate 7 rises, the slide bar 5 rises synchronously, and the slide bar 5 drives the clamp block 4 to rise synchronously.

[0037] like Figure 2 and 4 As shown, the elastic telescopic component also includes a sliding key 8, which is fixed in the central axis hole of the grounding block 2. A sliding groove 501 is opened on the sliding rod 5, and the sliding groove 501 is slidably matched with the sliding key 8.

[0038] Specifically, the sliding key 8 is used to guide the sliding rod 5 to prevent it from rotating.

[0039] Principle: During hanging, the staff lifts the present invention to align the wire 13 with the interval between the two grounding rods 3, the wire 13 abuts against the top surface of the clamping block 4 and continues to lift the present invention, the wire 13 presses the clamping block 4 downward, the slide bar 5 and the limit plate 7 overcome the tension of the tension spring 6 and descend, when the wire 13 is lower than the end of the hook section 301, the insulating operating rod 1 can be rotated to align the hook section 301 with the wire 13, and then the insulating operating rod 1 is slowly released, the tension spring 6 provides an upward tension to the limit plate 7, the limit plate 7 can rise, when the limit plate 7 rises, the slide bar 5 rises synchronously, the slide bar 5 drives the clamping block 4 to rise synchronously, the clamping block 4 rises and enters the hook section 301, forming Figure 1 and Figure 2 In the form shown, the conductor 13 is clamped by the clamp block 4 and the grounding rod 3. To remove the present invention, the staff lifts the present invention, the conductor 13 presses the clamp block 4 downward, the slide bar 5 and the limit plate 7 overcome the tension of the tension spring 6 and descend, and when the conductor 13 is lower than the end of the hook section 301, the insulating operating rod 1 can be rotated so that the conductor 13 is located between the two grounding rods 3, and the present invention can be removed.

[0040] Example 2

[0041] Embodiment 2 is implemented on the basis of embodiment 1.

[0042] It also includes an insulating pull rod 9, the top end of the insulating pull rod 9 is connected to the limiting plate 7, and the bottom end of the insulating pull rod 9 protrudes out of the bottom end of the insulating operating rod 1.

[0043] Specifically, the insulating pull rod 9 can be made of, but not limited to, glass fiber reinforced plastics, and can also be made of, for example, epoxy resin or other insulating materials. In order to manually control the descent of the slide bar 5, an insulating pull rod 9 is designed. It can extend from the bottom end of the insulating operating rod 1, and the tension of the tension spring 6 is overcome by pulling the insulating pull rod 9, so that the clamp 4 is withdrawn from the hook section 301. In this embodiment, the wire 13 does not need to press the clamp 4, which reduces the probability that the method in embodiment 1 may damage the wire 13.

[0044] One connection mode between the insulating pull rod 9 and the limiting plate 7 is: the top end of the insulating pull rod 9 is fixedly connected to the bottom end of the limiting plate 7 (this mode is not shown in the drawings).

[0045] Example 3

[0046] The difference between Example 3 and Example 2 is that the fixing method of the insulating pull rod 9 and the limiting plate 7 is different.

[0047] Another connection mode of the insulating pull rod 9 and the limiting plate 7 is: a hinge support 701 is fixed to the bottom end of the limiting plate 7 , and the top end of the insulating pull rod 9 is hinged to the hinge support 701 .

[0048] Example 4

[0049] Embodiment 4 is implemented on the basis of embodiment 3, and a handle assembly is also designed to more conveniently operate the insulating pull rod 9.

[0050] The handle assembly includes a fixed handle 10 and a movable handle 11. A ring 12 is fixed to one side of the top of the fixed handle 10. The ring 12 is sleeved on the bottom end of the insulating operating rod 1, and the ring 12 is fixedly connected to the insulating operating rod 1. The movable handle 11 is located below the insulating operating rod 1. One end of the movable handle 11 is hinged to the fixed handle 10, and the rotation axis of the movable handle 11 is parallel to the rotation axis of the hinge support 701. The bottom end of the insulating pull rod 9 is hinged to the middle of the movable handle 11.

[0051] Specifically, by swinging the movable handle 11 away from the insulating operating rod 1, the movable handle 11 pulls the insulating pull rod 9 downward, the limit plate 7 descends, the limit plate 7 drives the slide bar 5 to descend, and the slide bar 5 and the clamping block 4 descend with the limit plate 7. The collar 12 is bonded or threaded to the insulating operating rod 1.

[0052] A configuration mode of the hinge support 701: the rotation axis of the hinge support 701 intersects perpendicularly with the center axis of the insulating operating rod 1 (this mode is not shown in the accompanying drawings)).

[0053] Another arrangement of the hinge support 701 is as follows: the rotation axis of the hinge support 701 is perpendicular to the central axis of the insulating operating rod 1 , and the rotation axis of the hinge support 701 is located on one side of the central axis of the insulating operating rod 1 .

[0054] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other, and the embodiments can be combined with each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0055] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
