[0001] The invention relates to the technical field of electric power maintenance equipment, and in particular to an adjustable conductor end short-circuit grounding wire. Background Art

[0002] In the daily maintenance work of substations, grounding wires play an important role in directing possible incoming electricity to the grounding grid. They are indispensable safety tools for protecting personal safety during work.

[0003] Among them, CN107425307A discloses a universal grounding wire, including a grounding head, a connecting plug is provided at one end of the grounding head, the connecting plug is detachably connected to a first connecting seat, the first connecting seat is rotatably connected to a second connecting seat, a rotation limiting mechanism is provided between the first connecting seat and the second connecting seat, the second connecting seat is electrically connected to the first connecting seat, the second connecting seat is connected to an insulating rod, and a grounding wire is provided on the second connecting seat.

[0004] The grounding head in the above-mentioned universal grounding wire includes a main body structure in the shape of an inverted "U" and two clamping springs arranged opposite to each other in the main body structure; when hanging on the transmission line, the transmission line is slid into the opening at the bottom of the main body structure and then clamped and fixed by the two clamping springs. Because the two clamping springs are both arc-shaped and arranged in opposite directions, the clamping stability of the transmission line is relatively poor. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an adjustable conductor end short-circuit grounding wire to solve the problem in the prior art that the power transmission line is clamped only by the cooperation of two clamping springs, resulting in relatively poor clamping stability.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an adjustable conductor end short-circuit grounding wire, including a grounding head, the grounding head including a main body structure and two elastic clips arranged in an installation space formed in the main body structure, the two elastic clips are both arc-shaped and the clamping area formed between the two elastic clips first decreases and then increases from one end opening to the other end opening, a hanging notch connected to one end of the clamping area is formed on one side wall of the main body structure, and a stop block that slides to the shrinkage in the middle of the clamping area is connected to the other end of the clamping area through an elastic support member.

[0007] Technical principle:

[0008] When the grounding head is hung on the transmission line, the grounding head moves to one side of the transmission line, and then the transmission line is slid into the clamping area from the hanging notch, and the grounding head is moved to make the transmission line pass from one end of the clamping area through the necking in the middle of the clamping area and enter the other end of the clamping area. Not only is the transmission line clamped and fixed by the elastic clip, but the elastic support member also continuously provides a resisting force for the resisting block, ensuring that the resisting block stably resists one side of the transmission line, and cooperates with the necking in the middle of the clamping area to limit the position, so as to stably clamp and fix the transmission line.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The adjustable conductor end short-circuit grounding wire is provided with a hanging notch on one side wall of the main body structure, so that the transmission line can be conveniently moved from the hanging notch into the clamping area, and then the transmission line is stably clamped and fixed through the cooperation of the elastic support member, the stop block, the constriction in the middle of the clamping area and the two elastic clips, thereby ensuring that the transmission line can be grounded smoothly and safely.

[0013] The figure marks in the drawings of the specification include: grounding head 1, main body structure 101, elastic clip 102, hanging notch 103, elastic support member 2, stop block 3, receiving block 4, first connecting rod 5, second connecting rod 6, angle adjustment member 7, adjusting screw 701, adjusting sleeve 702, traction rod 703, connecting sleeve 8, locking member 9, insulating rod 10. DETAILED DESCRIPTION

[0014] The present invention is further described in detail below through specific embodiments:

[0015] The grounding head 1 in the existing universal grounding wire includes a main body structure 101 in the shape of an inverted "U" and two clamping springs arranged opposite to each other in the main body structure 101; when clamping and fixing the transmission line, the two clamping springs are used to clamp the transmission line, resulting in relatively poor clamping stability. In order to solve this problem, Figure 1As shown, an embodiment of the present invention proposes an adjustable conductor end short-circuit grounding wire, including a grounding head 1, wherein the grounding head 1 includes a main body structure 101 and two elastic clips 102 arranged in an installation space formed in the main body structure 101, the two elastic clips 102 are both arc-shaped, and the clamping area formed between the two elastic clips 102 first decreases and then increases from one end opening to the other end opening, a hanging notch 103 connected to one end of the clamping area is formed on one side wall of the main body structure 101, and a stop block 3 that slides to the shrinkage in the middle of the clamping area is connected to the other end of the clamping area through an elastic support member 2.

[0016] During use: when the grounding head 1 is hung on the transmission line, the grounding head 1 moves to one side of the transmission line, and then the transmission line is slid into the clamping area from the hanging notch 103, and the grounding head 1 is moved to allow the transmission line to pass from one end of the clamping area through the necking in the middle of the clamping area and enter the other end of the clamping area. Not only is the transmission line clamped and fixed by the elastic clip 102, but the elastic support member 2 is also used to continuously provide a resisting force for the abutment 3, ensuring that the abutment 3 stably resists one side of the transmission line, and cooperates with the necking in the middle of the clamping area to limit the position, so as to stably clamp and fix the transmission line.

[0017] The adjustable conductor end short-circuit grounding wire is provided with a hanging notch 103 on one side wall of the main body structure 101, so as to facilitate moving the transmission line from the hanging notch 103 into the clamping area, and then stably clamping and fixing the transmission line through the cooperation of the elastic support member 2, the stop block 3, the constriction in the middle of the clamping area and the two elastic clips 102, thereby ensuring that the transmission line can be grounded smoothly and safely.

[0018] In this embodiment, due to the shape design of the power transmission line, in order to increase the contact area between the block 3 and the power transmission line, so as to improve the stability of the power transmission line when it is clamped and fixed, the block 3 is an arc-shaped block and the middle part thereof is bent toward the elastic support member 2; the elastic support member 2 can be an elastic telescopic rod or a support spring to continuously provide a stable resisting force for the block 3.

[0019] In addition, the adjustable conductor end short-circuit grounding wire can stably clamp and fix transmission lines of different thicknesses within a certain range through the cooperation of the elastic support member 2, the stopper 3, the constriction in the middle of the clamping area, and the two elastic clips 102.

[0020] In order to more clearly understand the adjustable conductor end short-circuit grounding wire, its structure will be further optimized below.

[0021] like Figure 1As shown, according to another embodiment of the present invention, the adjustable conductor end short-circuit grounding wire, wherein the two elastic clips 102 are arranged up and down, and the clamping area is arranged inclined upward from one end connected to the hanging port to the other end.

[0022] In this embodiment, the arrangement of the clamping area is that the two elastic clips 102 are arranged obliquely in the installation space, and the ends of the two elastic clips 102 facing the hanging opening are both low ends; such an arrangement has an advantage: when the power transmission line is clamped and fixed at the stop block 3, the constriction in the middle of the clamping area and between the two elastic clips 102, the power transmission line generally shakes in the left and right directions when there is wind, and the elastic clip 102 located above is bent toward the elastic clip 102 below to form a resistance for the power transmission line to escape from the clamping area, and the power transmission line can also be stably clamped and fixed under a certain degree of shaking.

[0023] like Figure 1 As shown, according to another embodiment of the present invention, in the adjustable conductor end short-circuit grounding wire, the elastic clip 102 is provided with slideways along the sliding direction of the stop block 3, and the two ends of the stop block 3 are slidably arranged in the two slideways in a one-to-one correspondence. In this embodiment, the arrangement of the two slideways is to improve the installation and sliding stability of the stop block 3.

[0024] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, an adjustable conductor end short-circuit grounding wire, wherein the main body structure 101 is provided with a receiving block 4 connected thereto, and the top surface of the receiving block 4 and the lower inner side surface of the hanging notch 103 are on the same plane or the bottom surface of the receiving block 4 and the upper inner side surface of the hanging notch 103 are on the same plane.

[0025] In this embodiment, the receiving block 4 is arranged horizontally and is formed integrally with the main body structure 101 .

[0026] like Figure 1 When the top surface of the receiving block 4 and the lower inner side surface of the hanging notch 103 are on the same horizontal plane, move the grounding head 1 to place the transmission line on the top surface of the receiving block 4, and then move the grounding head 1 closer to the transmission line. The transmission line slides from the hanging notch 103 into one end of the clamping area, and then the two elastic clips 102 are used to guide the transmission line to quickly slide into the clamping area. Finally, the elastic support member 2, the stop block 3, the necking in the middle of the clamping area and the two elastic clips 102 cooperate to stably clamp and fix the transmission line.

[0027] like Figure 2When the bottom surface of the receiving block 4 and the upper inner surface of the hanging notch 103 are on the same horizontal plane, move the grounding head 1 to make the transmission line contact with the bottom surface of the receiving block 4, and then move the grounding head 1 close to the transmission line, and the transmission line slides from the hanging notch 103 into one end of the clamping area, and then through the guiding effect of the two elastic clips 102, the transmission line is quickly slid into the clamping area, and then the transmission line is stably clamped and fixed through the cooperation of the elastic support member 2, the stop block 3, the shrinkage in the middle of the clamping area and the two elastic clips 102.

[0028] In summary, the design of the receiving block 4 helps the user to quickly move the power transmission line into the hanging gap 103 .

[0029] like Figure 1 As shown, according to another embodiment of the present invention, the adjustable conductor end short-circuit grounding wire also includes a first connecting rod 5, a second connecting rod 6 and an angle adjustment member 7, one end of the first connecting rod 5 is detachably connected to the main body structure 101; one end of the second connecting rod 6 is rotatably connected to the other end of the first connecting rod 5 through a rotating member; the angle adjustment member 7 is connected between the first connecting rod 5 and the second connecting rod 6 and is used to adjust the first connecting rod 5 and the second connecting rod 6 to form any desired angle.

[0030] In this embodiment, the first connecting rod 5 and the main body structure 101 can be detachably connected using an existing first connecting structure, and the rotating member includes a first connecting seat connected to the first connecting rod 5 and a second connecting seat connected to the second connecting rod 6, and the first connecting seat and the second connecting seat are rotatably connected via a rotating shaft.

[0031] In the prior art, there is a rotation limiting mechanism between the first connecting seat and the second connecting seat, and the rotation limiting mechanism includes a positioning pin and a plurality of positioning grooves. The positioning pin is adjusted to cooperate with any positioning groove, so as to stably adjust the angle formed between the first connecting rod 5 and the second connecting rod 6. Such a design enables the first connecting rod 5 and the second connecting rod 6 to be adjusted only between a few fixed angles, and the applicability is relatively poor. In this embodiment, the angle adjustment member 7 can form any desired angle between the first connecting rod 5 and the second connecting rod 6, and the applicability is stronger.

[0032] Specifically, the angle adjustment member 7 includes an adjusting screw 701, an adjusting sleeve 702 and a traction rod 703, wherein one end of the adjusting screw 701 is rotatably connected to the second connecting rod 6; the adjusting sleeve 702 is threadedly connected to the adjusting screw 701; one end of the traction rod 703 is rotatably connected to the adjusting sleeve 702 and the other end thereof is rotatably connected to the first connecting rod 5.

[0033] When the angle between the first connecting rod 5 and the second connecting rod 6 needs to be adjusted to find a suitable force angle, the adjusting sleeve 702 is driven to move axially on the adjusting screw 701 only by rotating the adjusting screw 701, and the first connecting rod 5 is driven to rotate around the rotating axis by the traction rod 703, so as to adjust the angle between the first connecting rod 5 and the second connecting rod 6. At the same time, the cooperation of the adjusting screw 701, the adjusting sleeve 702 and the traction rod 703 can also ensure that the angle between the first connecting rod 5 and the second connecting rod 6 is stably maintained during use.

[0034] The adjusting screw 701 may be rotatably connected to the second connecting seat.

[0035] The second connecting rod 6 is rotatably connected with a connecting sleeve 8, and one end of the adjusting screw 701 is inserted into the connecting sleeve 8 and fixed by a locking member 9. In this way, the adjusting screw 701 can be quickly connected to the second connecting rod 6, wherein the connecting sleeve 8 can also be rotatably connected to the second connecting seat.

[0036] In this embodiment, the locking member 9 includes a locking rod, which passes through the connecting sleeve 8 and the adjusting screw 701 in the radial direction of the adjusting screw 701, and the two ends of the locking rod are threadedly connected with locking caps that abut against the outer wall of the connecting sleeve 8. Specifically, the connecting sleeve 8 has two first connecting holes arranged in the radial direction thereof, and one end of the adjusting screw 701 has a second connecting hole arranged in the radial direction thereof. After the end of the adjusting screw 701 with the second connecting hole is inserted into the connecting sleeve 8 and abutted against each other, the second connecting holes are aligned and connected between the two first connecting holes, one end of the locking rod passes through the two first connecting holes and the second connecting hole, and then the locking caps are threadedly connected to both ends of the locking rod, and the two locking caps abut against the outer wall of the connecting sleeve 8, so as to complete the connection between the adjusting screw 701 and the second connecting rod 6 or the second connecting seat.

[0037] like Figure 2 As shown, according to another embodiment of the present invention, the adjustable conductor end short-circuit grounding wire further includes an insulating rod 10, one end of which is detachably connected to the end of the second connecting rod 6 away from the first connecting rod 5 through the existing second connecting structure. Here, the insulating rod 10 is convenient for the user to hold and install to operate the adjustable conductor end short-circuit grounding wire, slide the transmission line into the clamping area, and stably clamp and fix the transmission line through the cooperation of the elastic support 2, the stopper 3, the constriction in the middle of the clamping area, and the two elastic clips 102.

[0038] The grounding head 1, the first connecting structure, the first connecting rod 5, the rotating member and the second connecting rod 6 are all made of conductive materials. An electrical connection terminal is connected to the second connecting rod 6, and the grounding wire is connected through the electrical connection terminal.

[0039] The operation of the adjustable conductor end short-circuit grounding wire when in use is as follows:

[0040] First connect the ground wire to the electrical connection terminal to ground;

[0041] Then hold the adjusting screw 701 and rotate it to adjust the angle between the first connecting rod 5 and the second connecting rod 6 to the desired appropriate force angle;

[0042] Hold the insulating rod 10 to move the grounding head 1 until the transmission line fits on the receiving block 4, then move the grounding head 1 close to the transmission line, and the transmission line slides into one end of the clamping area from the hanging notch 103, and then the transmission line is quickly slid into the clamping area through the guiding effect of the two elastic clips 102, and finally the transmission line is stably clamped and fixed through the cooperation of the elastic support member 2, the stop block 3, the necking in the middle of the clamping area and the two elastic clips 102.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
