Description

Technical Field

[0001] The utility model relates to the technical field of UHV power transmission and transformation lines, in particular to a telescopic type current lead spacer. Background Art

[0002] In UHV power transmission and transformation lines, in order to improve the power transmission capacity and economic benefits of the lines and suppress the occurrence of power transmission line accidents and their related hazards, the method of bundled conductors needs to be adopted. When the method of bundled conductors is used, a certain distance needs to be maintained between the bundled conductors and they are arranged in a polygon, which can play a role equivalent to increasing the conductor diameter, making it not easy to generate corona and improving the power transmission capacity at the same time. However, when the current leads of the upper two conductors are introduced in the bundled conductors, they will touch the lower two conductors. Under the influence of external factors such as wind, the conductors swing, and it is easy for the current leads of the upper layer conductors to touch the fittings on the lower layer conductors. Long-term operation will cause damage to the current leads and fittings. In order to ensure a reasonable gap between the current leads and the fittings on the conductor string and avoid damage caused by the conductor dancing and colliding with the fittings, a current lead spacer needs to be installed between the current leads and the fittings on the lower layer conductor string.

[0003] During the use of the existing current lead spacer, two wire clamps are connected to a threaded rod through a sleeve. Although this method can provide a reasonable gap between the current leads and the fittings on the conductor string, under the influence of the external environment of wind, the threaded rod connected by the sleeve will become ineffective after long-term use, thus affecting the service life of the spacer.

[0031] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] It should be noted that the features in the embodiments of the present utility model can be combined with each other without conflict.

[0033] Please also combine Figures 1 to 3 , and now the telescopic type drain wire spacer provided by the present utility model will be described.

[0034] The telescopic type drain wire spacer includes a first wire clamp 1, a second wire clamp 2, a telescopic rod 3, a mounting rod 4, and an elastic member 5. The first wire clamp 1 is connected to the telescopic rod 3, the second wire clamp 2 is connected to the mounting rod 4. The mounting rod 4 is provided with a sliding groove 41, the telescopic rod 3 is installed in the sliding groove 41 and can slide in the sliding groove 41. The elastic member 5 is installed in the sliding groove 41 and elastically abuts between the telescopic rod 3 and the groove wall of the sliding groove 41. Specifically, the elastic member 5 can be a spring. Of course, the elastic member 5 can also be elastically connected between the telescopic rod 3 and the groove wall of the sliding groove 41.

[0035] It can be understood that the first wire clamp 1 of the telescopic drainage wire spacer is connected to the telescopic rod 3, and the second wire clamp 2 is connected to the mounting rod 4. The mounting rod 4 is provided with a sliding groove 41. The telescopic rod 3 is installed in the sliding groove 41 and can slide in the sliding groove 41. The elastic member 5 is installed in the sliding groove 41 and elastically abuts between the telescopic rod 3 and the groove wall of the sliding groove 41, so that the first wire clamp 1 and the second wire clamp 2 can move telescopically with respect to each other. Even in a windy external environment, since the first wire clamp 1 and the second wire clamp 2 are not rigidly connected, the first wire clamp 1 and the second wire clamp 2 will not break and fail, thereby improving the service life of the spacer rod.

[0036] It should be noted that in a windy external environment, the telescopic rod 3 can move in the sliding groove 41, and the telescopic rod 3 and the groove wall of the sliding groove 41 squeeze the elastic member 5, causing the elastic member 5 to undergo elastic deformation, so that the first wire clamp 1 and the second wire clamp 2 can move relative to each other.

[0037] In this embodiment, the telescopic rod 3 includes a sliding portion 31 and an abutting portion 32 connected to the sliding portion 31, and the abutting portion 32 elastically abuts against the elastic member 5. By providing the abutting portion 32, the elastic deformation force of the elastic member 5 can fully act on the telescopic rod 3, so that the telescopic rod 3 can move in the sliding groove 41.

[0038] Specifically, the diameter of the contact portion 32 is greater than the diameter of the sliding portion 31 .

[0039] Furthermore, the telescopic drain wire spacer also includes a ball 6, and the groove wall of the sliding groove 41 is provided with a mounting groove, and the ball 6 is rollingly connected in the mounting groove and rollingly connected with the sliding part 31. Since there is a certain gap between the sliding part 31 and the groove wall of the sliding groove 41, in order to prevent the sliding part 31 from shaking in the sliding groove 41, the ball 6 is provided so that the sliding part 31 can move stably in the sliding groove 41. In addition, since the ball 6 is provided, the friction of the sliding part 31 in the sliding groove 41 can be reduced, so that the sliding part 31 can move smoothly.

[0040] Furthermore, the ball 6 abuts against the abutment portion 32 and is used to prevent the sliding portion 31 from being separated from the sliding groove 41. Since the ball 6 can abut against the abutment portion 32, when the displacement of the sliding portion 31 in the sliding groove 41 is large, the abutment portion 32 can abut against the ball 6, thereby preventing the sliding portion 31 from being separated from the sliding groove 41, thereby preventing the spacer from failing.

[0041] Furthermore, a plurality of balls 6 are provided and are spaced apart along the circumferential direction of the sliding groove 41, and a plurality of mounting grooves are provided and are arranged one by one corresponding to the balls 6. By providing a plurality of balls 6, the circumferential direction of the sliding part 31 can be rollingly connected with the balls 6, thereby ensuring the stability of the movement of the sliding part 31.

[0042] In one embodiment, as Figure 1 and Figure 3 shown, the first wire clamp 1 includes a first clamp 11, a second clamp 12 and a first fastener 13. The first clamp 11 is connected to the telescopic rod 3 and is rotatably connected to the second clamp 12. The first fastener 13 is rotatably connected to the second clamp 12 and is used to abut against the first clamp 11. By providing the first clamp 11 and the second clamp 12, the drainage wire can be fixed between the first clamp 11 and the second clamp 12, and the first fastener 13 then fastens the first clamp 11 and the second clamp 12, so that the first clamp 11 and the second clamp 12 can maintain the current clamping position.

[0043] In this embodiment, the first clamp 11 is provided with a first groove 111. The first fastener 13 includes a first connecting portion 131 and a first fastening portion 132 threadedly connected to the first connecting portion 131. The first connecting portion 131 is disposed in the first groove 111, and the first fastening portion 132 is rotated so that the first fastening portion 132 abuts against the first clamp 11. When the first clamp 11 and the second clamp 12 fix the drainage wire therebetween, the first connecting portion 131 can penetrate through the first groove 111 and be disposed in the first groove 111. The first fastening portion 132 is rotated so that the first fastening portion 132 abuts against the first clamp 11, thereby fixing the first clamp 11 and the second clamp 12 in the current position.

[0044] Of course, in other embodiments, the second clamp 12 is provided with a first avoidance groove. When the first clamp 11 and the second clamp 12 fix the drainage wire therebetween, the first connecting portion 131 can move in the first avoidance groove so that the first connecting portion 131 can move into the first groove 111. The first fastening portion 132 is rotated so that the first fastening portion 132 abuts against the first clamp 11, thereby fixing the first clamp 11 and the second clamp 12 in the current position.

[0045] In one embodiment, continuing as Figure 1 and Figure 3 shown, the second wire clamp 2 includes a third clamp 21, a fourth clamp 22 and a second fastener 23. The third clamp 21 is connected to the mounting rod 4 and is rotatably connected to the fourth clamp 22.

By providing the third clamp 21 and the fourth clamp 22, the drainage wire can be fixed between the third clamp 21 and the fourth clamp 22, and the second fastener 23 then fastens the third clamp 21 and the fourth clamp 22, so that the third clamp 21 and the fourth clamp 22 can maintain the current clamping position.

[0046] In this embodiment, the third clip 21 is provided with a second groove 211. The second fastener 23 includes a second connecting portion 231 and a second fastening portion 232 threadedly connected to the second connecting portion 231. The second connecting portion 231 is disposed within the second groove 211. Rotate the second fastening portion 232 so that the second fastening portion 232 abuts against the third clip 21. When the third clip 21 and the fourth clip 22 fix the drainage line therebetween, the second connecting portion 231 can penetrate through the second groove 211 and be disposed within the second groove 211. Rotate the second fastening portion 232 so that the second fastening portion 232 abuts against the third clip 21, thereby fixing the third clip 21 and the fourth clip 22 in the current position.

[0047] Certainly, in other embodiments, the fourth clip 22 is provided with a second avoidance groove. When the third clip 21 and the fourth clip 22 fix the drainage line therebetween, the second connecting portion 231 can move within the second avoidance groove so that the second connecting portion 231 can move into the second groove 211. Rotate the second fastening portion 232 so that the second fastening portion 232 abuts against the third clip 21, thereby fixing the third clip 21 and the fourth clip 22 in the current position.

[0048] The technical features of the above-described embodiments can be combined arbitrarily.
