Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to an insulating spacer bar. Background Technology

[0002] Insulating spacers are hardware installed on split conductors to fix the spacing between them, preventing conductors from whipping each other, suppressing wind vibrations and secondary span oscillations, and ensuring the insulation distance between adjacent split conductors. However, with changes in the ecological environment, the number of birds has increased, their activity areas have expanded, and the frequency of bird activity has increased, leading to frequent bird-related accidents. Furthermore, with the continuous increase in voltage levels, the insulation requirements between the lead-in conductor and the ground wire or tower have also increased. Therefore, to reduce bird-related tripping, the original lead-in conductors have undergone insulation modification to improve the insulation level between the lead-in conductor and the ground wire or tower, reducing the probability of bird droppings flashover. After the insulation modification, the surface of the lead-in conductor will be covered with an insulating layer, which must be ensured to operate under stable and safe conditions during operation.

[0003] According to research, existing insulating spacers typically use bolts on the spacer body and nuts on the bolts to constrain the clamps. However, during actual use, the insulating drain wires exert forces on the insulating spacers due to vibration, causing the nuts to be continuously squeezed. Eventually, the nuts move relative to the bolts, resulting in the failure of the fixing between the insulating spacer and the insulating drain wire. The insulating spacer slides relative to the insulating drain wire, which easily causes wear on the insulating drain wire. Furthermore, the existing insulating spacers have a fixed overall length and cannot adjust their spacing distance as needed. Utility Model Content

A wire clamp 1 is connected, and a fixing component is rotatably connected to each of the two wire clamps 1. The fixing component includes a second screw 12, a second connecting sleeve 6, a base 7, and a second limiting rod 14. The second screw 12 is rotatably connected to the wire clamp 1, the second connecting sleeve 6 is threadedly connected to the second screw 12, and the second connecting sleeve 6 is rotatably connected to the base 7. The surface of the second connecting sleeve 6 is provided with ratchet teeth that cooperate with the second limiting rod 14. The second limiting rod 14 is connected to the base 7, and the base 7 is connected to the second screw 12.

[0027] In a preferred but non-limiting embodiment of this utility model, a first limiting rod 5 is slidably connected to the adjusting sleeve 9. The first limiting rod 5 passes through the adjusting sleeve 9, and a first spring 16 is provided between the first limiting rod 5 and the adjusting sleeve 9. The first spring 16 pushes the first limiting rod 5 into the limiting groove 17.

[0028] In a preferred but non-limiting embodiment of this utility model, the first connecting sleeve 4 is provided with a limiting groove 17 that cooperates with the first limiting rod 5 at one end near the first limiting rod 5, and the first limiting rod 5 is L-shaped.

[0029] In a preferred but non-limiting embodiment of this utility model, the limiting groove 17 is circumferentially linearly distributed on the surface of the first connecting sleeve 4.

[0030] In a preferred but non-limiting embodiment of this utility model, the base 2 and the limiting member are both provided with grooves on the side close to each other, and an elastic clamp 8 is provided in the groove.

[0031] In a preferred but non-limiting embodiment of this utility model, a rotating shaft 11 is provided at one end of the second screw 12, and the second screw 12 is rotatably connected to the wire clamp 1 by means of the rotating shaft 11.

[0032] In a preferred but non-limiting embodiment of the present invention, a connecting rod 13 is provided on the second screw 12, and the connecting rod 13 passes through the base 7 and is slidably connected to the base 7.

[0033] In a preferred but non-limiting embodiment of the present invention, the second connecting sleeve 6 is provided with a plurality of ratchet teeth, which are linearly distributed circumferentially on the surface of the second connecting sleeve 6.

[0034] In a preferred but non-limiting embodiment of the present invention, the second limiting rod 14 passes through the base 7 and is slidably connected to the base 7, and a second spring 15 is provided on the second limiting rod 14.

[0035] In a preferred but non-limiting embodiment of the present invention, the second spring 15 is located on the surface of the second limiting rod 14 away from the ratchet, and the second spring 15 pushes the second limiting rod 14 to abut against the ratchet.

[0036] Working principle:

[0037] Bring this device to the work area, such as Figure 4 As shown, the second limiting rod 14 is pushed upward to disengage it from the ratchet, and the second spring 15 is compressed. At this time, the second connecting sleeve 6 can be rotated in the opposite direction to rotate along the second screw 12 and move away from the rotating shaft 11. The second connecting sleeve 6 drives the base 7 to move away from the base 2 along the connecting rod 13. After the base 7 moves to the appropriate position, the second limiting rod 14 is released. The second spring 15 pushes the second limiting rod 14 to abut against the ratchet. Then, the wire clamp 1 is rotated in the opposite direction along the connection point between the base 2 and the wire clamp 1, thereby opening the wire clamp 1.

[0038] Pull the first limiting rod 5 to disengage it from the limiting groove 17. The first spring 16 is compressed. Rotate the first connecting sleeve 4 to drive the adjusting sleeve 9 to slide along the slide rod 10, thereby adjusting the interval between the two bases 2. Fix the two insulated drain wires at the required interval. The effect is good. After the adjustment is completed, release the first limiting rod 5. The first spring 16 pushes the first limiting rod 5 into the limiting groove 17 to prevent the first connecting sleeve 4 from rotating on its own.

[0039] Move the device so that the insulated drain wire is located in the groove of the base 2. Then rotate the clamp 1 forward along the connection point between the base 2 and the clamp 1, so that the clamp 1 and the base 2 fit together to cover the insulated drain wire. Rotate the second connecting sleeve 6 forward so that it rotates along the second screw 12 and approaches the rotating shaft 11. The second connecting sleeve 6 drives the base 7 to approach the base 2 along the connecting rod 13 until it abuts against the base 2. When the second connecting sleeve 6 rotates forward, the second connecting sleeve 6 drives the ratchet to rotate and can push the second limiting rod 14 to squeeze the second spring 15. The second limiting rod 14 cannot restrict the forward rotation of the second connecting sleeve 6. When the insulated drain wire vibrates and applies force to the device, the reverse rotation of the second connecting sleeve 6 needs to drive the ratchet to move synchronously. However, the second limiting rod 14 always abuts against the ratchet, which will interfere with the reverse rotation of the second connecting sleeve 6, thereby avoiding fixation failure.

[0040] The beneficial effect of this utility model is that, compared with the prior art,

[0041] 1. The length of the spacer body of this utility model can be adjusted as needed, thereby adjusting the spacing between the two bases to fix the two insulated guide wires at the required interval, resulting in good performance.

[0042] 2. This utility model uses a fixing component that can limit the direction of rotation to fix the base and the wire clamp, preventing the overall fixation failure caused by the vibration of the insulated lead wire, avoiding the sliding of this utility model relative to the insulated lead wire, and thus avoiding wear of the insulated lead wire.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
