[0002] OPGW (Optical Fiber-Coated Wire) is a structure in which optical fibers are placed in the ground wire of an overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structure has the dual functions of ground wire and communication and is also known as OPGW optical cable.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0056] Please see Figures 1 to 7 The present application provides a fixed support for the installation of OPGW fiber optic composite ground wire in an overhead power distribution line, comprising: a connecting plate 1, a steering adjustment component and a telescopic control component; the connecting plate 1 is used to connect the crossarm, and a convex shaft 8 is provided on the connecting plate 1.

[0057] The steering adjustment assembly includes a rotating plate 6 and a positioning rod 10. The rotating plate 6 is rotatably mounted on the connecting plate 1 around the convex shaft 8. The connecting plate 1 has a plurality of positioning holes 9 evenly distributed around the convex shaft 8. The positioning rod 10 is detachably passed through the rotating plate 6 and extends into the positioning hole 9 to limit the rotation of the rotating plate 6.

[0058] Please refer to Figure 6 The rotating plate 6 is provided with a through hole 7. The convex shaft 8 rotates through the through hole 7, allowing the rotating plate 6 to rotate around the convex shaft 8. The positioning rod 10 can be a screw.

[0059] A support plate 11 is provided on the rotating plate 6; the telescopic adjustment assembly includes: a sleeve 13, two extrusion tubes 17, and a cable tie tube 20; the sleeve 13 is rotatably mounted on the support plate 11, and both ends of the sleeve 13 along the axial direction are provided with external thread sections with opposite rotation directions; the extrusion tubes 17 are provided with internal thread sections, and the two extrusion tubes 17 are respectively threaded to both ends of the sleeve 13; two anti-rotation inserts 19 are fixed on the connecting plate 1; the extrusion tubes 17 are provided with slots 18 along the axial direction; the two anti-rotation inserts 19 can slide into the slots 18 of the two extrusion tubes 17 to limit the rotation of the extrusion tubes 17; the cable tie tube 20. The tube 20 passes through the two extrusion tubes 17, and clamping structures are provided at both ends of the cable bundle tube 20. The clamping structures include: multiple side grooves 22 and multiple clamping blocks 24. The multiple side grooves 22 are arranged circumferentially around the cable bundle tube 20. The clamping blocks 24 are rotatably disposed in the side grooves 22 along the radial direction of the cable bundle tube 20. The inner end of the clamping block 24 extends into the cable bundle tube 20 and the outer end extends out of the cable bundle tube 20 at both ends along the radial direction of the cable bundle tube 20. The multiple clamping blocks 24 correspond one-to-one with the multiple side grooves 22. The sleeve 13 is used to drive the two extrusion tubes 17 away from each other during rotation, thereby pushing the clamping blocks 24 to rotate towards the center of the cable bundle tube 20.

[0060] Specifically, after installing the connecting plate 1 on the crossarm, the OPGW fiber is passed through the cable bundle tube 20. Then, the sleeve 13 is rotated, which in turn causes the clamping block 24 to rotate via the push tube 17, clamping the OPGW fiber and completing the installation and fixation of the OPGW fiber. Compared to existing methods using connecting hardware, this method more conveniently fixes the OPGW fiber to the crossarm and allows for adjustment of the rotation angle of the rotating plate 6 as needed. Specifically, when the positioning rod 10 is pulled out, the rotating plate 6 can rotate around the convex shaft 8 to adjust the axial direction of the cable bundle tube 20; after adjusting the cable bundle tube 20 to the appropriate position, the positioning rod 10 is passed through the rotating plate 6 and the positioning hole 9 to restrict the rotation of the rotating plate 6.

[0061] It should be noted that the clamping block 24 is rotatably connected to the cable tie tube 20 via the through shaft 23. Since the external threaded sections at both ends of the sleeve 13 rotate in opposite directions, the two extrusion tubes 17 can be moved in opposite directions when the sleeve 13 rotates. The slot 18 is located at the bottom of the extrusion tube 17, and both ends of the slot 18 are closed to prevent the anti-rotation insert 19 from slipping out of the slot 18. In addition, in order to better support the cable tie tube 20, a mountain-shaped plate 21 can also be fixed on the rotating plate 6; the mountain-shaped plate 21 is connected to the cable tie tube 20 and is used to provide support for the cable tie tube 20; and, in order to avoid the multiple clamping blocks 24 on the cable tie tube 20, the mountain-shaped plate 20 is set in a mountain shape.

[0062] In one embodiment, as shown in Figure 3, the outer end of the clamping block 24 is an inclined surface that engages with the wedge of the extrusion tube 17, so that the sliding extrusion tube 17 can better push the clamping block 24 to rotate.

[0063] In another embodiment, a rubber pad 25 is provided at the inner end of the clamp 24 to prevent the clamp 24 from damaging the optical fiber.

[0064] Furthermore, the clamping block 24 is an L-shaped block with the notch located on the inside; the clamping structure also includes a rubber block 26; the rubber block 26 is disposed on the notch of the clamping block 24.

[0065] By setting rubber block 26 and rubber pad 25, the optical fiber can be better protected while clamping it.

[0066] In one embodiment, to improve the stability of positioning the rotating plate 6, the positioning rod 10 includes two rods, which are symmetrically arranged about the convex axis 8.

[0067] In a more specific embodiment, a rotating ring 15 is fixed on the sleeve 13; a plurality of wrench slots 16 are evenly distributed around the circumference of the rotating ring 15.

[0068] The wrench slot 16 can be hexagonal, allowing a hexagonal wrench to be inserted, which then drives the sleeve 13 to rotate.

[0069] Furthermore, the support plate 11 includes two plates, each of which is provided with a through opening 12; the sleeve 13 is provided through the through openings 12 of the two support plates 11.

[0070] The two support plates 11 can provide more stable support for the sleeve 13.

[0071] Furthermore, a retaining ring 14 is fitted inside the opening 12; the sleeve 13 is located between the retaining rings 14 of the two support plates 11; the retaining rings 14 are used to restrict the axial movement of the sleeve 13.

[0072] The retaining ring 14 can be a baffle to prevent the sleeve 13 from moving axially; and both ends of the through hole 12 on the support plate 11 can be provided with retaining rings 14.

[0073] Furthermore, the connecting plate 1 is a C-shaped component with two parallel plates; each of the two parallel plates of the connecting plate 1 is provided with a snap groove 2; ear plates 3 are provided on both sides of the snap groove 2; and reserved holes 4 are provided on both the connecting plate 1 and the ear plates 3.

[0074] Specifically, when installing the connecting plate 1, the connection between the connecting plate 1 and the crossarm can be achieved by using bolts passing through the reserved holes 4.

[0075] Furthermore, a pad 5 is provided on the ear plate 3, and a rotating plate 6 is connected through the pad 5.

[0076] By setting the pad 5, a more stable support can be provided for the rotating plate 6.

[0077] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
