Description

Technical Field

[0001] The utility model relates to the technical field of electric power fittings, in particular to a pre-twisted interphase spacer rod. Background Art

[0002] The existing interphase spacer rods are connected by U-shaped rings, and the length is adjusted by an adjusting plate. When there is wind deviation, the U-shaped ring is severely damaged, and the adjusting plate can only be adjusted to a fixed value.

[0003] Existing interphase spacers mostly use wire clamps to clamp the conductors. During long-term operation, the wire clamps wear the conductors due to the dancing of the conductors.

[0004] Therefore, there is an urgent need for a more flexible pre-twisted phase spacer to achieve multi-directional rotation when there is wind deviation, while reducing the wear on the conductor as much as possible. Utility Model Content

[0005] The utility model aims to provide a more flexible pre-twisted phase spacer rod to realize multi-directional rotation when there is wind deviation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pre-twisted interphase spacer used to connect four parallel wires, comprising a first pre-twisted wire clamp, a first hanging plate, a second pre-twisted wire clamp, a universal joint, a turnbuckle screw with adjustable length, a spacer composite insulator, a third pre-twisted wire clamp, a second hanging plate and a fourth pre-twisted wire clamp connected in sequence from front to back;

[0008] The universal joint comprises a first rotating member, a transmission member and a second rotating member connected in sequence;

[0009] The front end of the first rotating member is rotatably connected to the second pre-twisted wire clamp and its rotation axis is perpendicular to the ground, and the rear end of the first rotating member is rotatably connected to the front end of the transmission member and its rotation axis is parallel to the conductor;

[0010] The rear end of the transmission member is rotatably connected to the front end of the second rotating member, and the rotation axis thereof is perpendicular to the ground; the rear end of the second rotating member is rotatably connected to the front end of the turnbuckle, and the rotation axis thereof is perpendicular to the ground.

[0011] Furthermore, a first opening is formed on a side of the first rotating member facing the transmission member, a front end of the transmission member extends into the first opening and is freely sleeved on the outside of the first bolt, and the first bolt and the first nut are fastened on the first opening;

[0012] The axis of the first bolt is parallel to the wire;

[0013] The second rotating member is provided with a second opening on one side facing the transmission member, the rear end of the transmission member extends into the second opening and is freely sleeved on the outside of the second bolt, and the second bolt and the second nut are fastened on the second opening; the axis of the second bolt is vertical.

[0014] Furthermore, the first opening is a U-shaped opening in a horizontal plane, and the second opening is a U-shaped opening in a vertical plane.

[0015] Furthermore, the front end and the rear end of the transmission component are respectively hemispherical.

[0016] Furthermore, the first hanging plate is a pair of symmetrically arranged clamps, the second pretwisted wire clamp is clamped at the rear ends of the two clamps, and the second pretwisted wire clamp is provided with an opening on a side facing the first rotating member for the front end of the first rotating member to extend into, and a bolt that can rotate freely relative to the first rotating member passes through the second pretwisted wire clamp and the first rotating member and is screwed into a nut.

[0017] Furthermore, the front end of the basket screw is two relatively arranged horizontal plates, and the rear end of the second rotating member extends parallel to the middle of the two horizontal plates. The bolt can be rotated relative to the rear end of the second rotating member to pass through the two horizontal plates and the second rotating member and screw into the nut.

[0018] Furthermore, the first pretwisted wire clamp, the second pretwisted wire clamp, the third pretwisted wire clamp and the fourth pretwisted wire clamp are pretwisted suspension wire clamps respectively.

[0019] In the above technical solution, the utility model has the following beneficial effects:

[0020] The utility model provides a pre-twisted phase-to-phase spacer that can adjust the phase spacing of the conductors by adjusting the length of the basket screw, for example, by rotating its left and right pull rods. In addition, the universal energy-saving realizes multi-directional rotation when there is wind deviation, improves the adaptability of the spacer to wind, and makes it more flexible. At the same time, a pre-twisted suspension wire clamp is used to replace the original wire clamp to solve the problem of wire wear when the wire dances. At the same time, a basket screw is used to replace the original adjustment plate, which can achieve fine-tuning of the phase distance of the conductors. The distance between the phase spacer rods matches the conductors accurately, which can effectively suppress the occurrence of line dancing. The entire structure adopts an open structure slot connection, which effectively avoids the disadvantages of the ring connection (the phase spacing changes with the conductor dancing), ensures the phase spacing of the conductors, and thus can effectively suppress the occurrence of line dancing.

[0040] The first pre-twisted wire clamp 1, the second pre-twisted wire clamp 3, the third pre-twisted wire clamp 8 and the fourth pre-twisted wire clamp 9 are respectively used to connect four parallel wires, and the length of the pre-twisted interphase spacer is perpendicular to the wire. Preferably, the first pre-twisted wire clamp, the second pre-twisted wire clamp, the third pre-twisted wire clamp and the fourth pre-twisted wire clamp are pre-twisted suspension wire clamps.

[0041] The first hanging plate 2 is used to ensure the interval between the first pre-twisted wire clamp 1 and the second pre-twisted wire clamp 3, and the second hanging plate is used to ensure the distance between the third pre-twisted wire clamp 8 and the fourth pre-twisted wire clamp 9. The structure of the first hanging plate 2 or the second hanging plate belongs to the prior art, and can be referred to the Chinese utility model patent with application number 201220597528.8 and patent name "A New Vertically Arranged Double Clamp Suspension Clamp".

The function of the bolt is to fasten the first hanging plate 2 and the second pre-twisted wire clamp 3 together, and the bolt also acts as a rotating shaft to realize the rotation of the first rotating member 41 relative to the second pre-twisted wire clamp 3 along the vertical axis.

[0043] The universal joint 4 includes, from front to back, a first rotating member 41 , a transmission member 42 , and a second rotating member 43 which are connected in sequence.
