Technical Field

[0001] This utility model belongs to the field of optical cable traction technology, specifically, it relates to a traction tension control device for power communication optical cables. Background Technology

[0002] In the field of power communication, optical cables, as an important carrier of signal transmission, are usually laid in outdoor environments and are subject to various external forces such as wind and vibration. When strong winds act on optical cables, the two ends of the cable are easily stretched due to sudden tension changes, which can lead to the breakage of internal optical fibers or damage to the outer sheath, thereby affecting communication stability and even causing line faults.

[0003] Existing technology uses steel towers to fix optical cables. However, since the optical cable is fixed to the steel tower and has a fixed length, it may be damaged when the two ends of the optical cable are stretched by tension in strong winds. Therefore, existing technology has certain drawbacks.

[0004] In view of this, this utility model is proposed. Utility Model Content

The optical cable is located in the cavity of the protective box in an "n" shape.

[0008] The protective device includes two sets of clamps, with two clamps in each set. A perforation is opened on each of the left and right side walls of the protective box. Both ends of the optical cable pass through the perforation and are located between two corresponding clamps. Both ends of the clamps are rounded.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 As shown, a power communication optical cable traction tension control device includes:

[0029] The traction device includes a protective box 10. A lifting plate 14 is installed inside the cavity of the protective box 10. Two first pulleys 12 are rotatably installed on the left and right sides of the front side wall of the lifting plate 14. Two second pulleys 13 are installed at the lower part of the cavity of the protective box 10. An optical cable 11 is movably connected to the side walls of the first pulleys 12 and the second pulleys 13. The optical cable 11 is located in the cavity of the protective box 10 in an "n" shape.

[0030] The protective device includes two sets of clamps 24, with two clamps 24 in each set. A through hole 21 is opened on each of the left and right side walls of the protective box 10. The two ends of the optical cable 11 pass through the through hole 21. The two ends of the optical cable 11 are respectively located between two corresponding clamps 24. The ends of the multiple clamps 24 are rounded.

[0031] In practical use, when encountering wind, the optical cable 11 will be blown, and then the optical cable 11 will pull the first pulley 12 downward to extend the optical cable inside the protective box 10 cavity, increasing the length of the optical cable outside, so as to cope with the wind and prevent the optical cable from being pulled and damaged due to the fixed ends of the optical cable. The protective device can protect the surface of the optical cable during the movement of the optical cable. In specific applications, the protective box 10 should be fixedly installed according to the situation to ensure the stability of the protective box 10.

[0032] In summary, by setting up a traction device and a protective device, the optical cable 11 can be pulled by the traction device to prevent damage caused by excessive wind force, and the surface of the optical cable 11 can be protected by the protective device. Compared with the existing technology, it has the characteristics of being easy to use and having a simple structure.

[0033] like Figure 2 and Figure 3 As shown, a fixing plate 16 is fixedly installed on both the upper and lower sides of the rear wall inside the cavity of the protective box 10, and a fixing strip 20 is fixedly installed on both the left and right sides of the side wall where the two fixing plates 16 are close to each other.

[0034] A torsion spring 17 is fixedly installed at the middle of the bottom wall of the upper fixed plate 16, and a threaded rod 15 is fixedly installed at the other end of the torsion spring 17. The bottom wall of the threaded rod 15 is rotatably connected to the top wall of the lower fixed plate 16.

[0035] The fixing bar 20 passes through the lifting plate 14 and is movably connected to the through point of the lifting plate 14; the threaded rod 15 passes through the lifting plate 14 and is threadedly connected to the through point of the lifting plate 14.

[0036] A rotating column 18 is fixedly installed on the rear side wall of each of the two second pulleys 13, and the rear side wall of each rotating column 18 is fixedly connected to the rear side wall of the cavity of the protective box 10.

[0037] In practical use, when the wind pulls the optical cable 11 outside the protective box 10, the optical cable 11 can pull the first pulley 12 downward. The movement of the first pulley 12 can drive the lifting plate 14 to move. Through the movement of the first pulley 12, the optical cable 11 located in the cavity of the protective box 10 can be extended from the through hole 21. During the movement of the lifting plate 14, the threaded connection with the threaded rod 15 can drive the threaded rod 15 to rotate. The rotation of the threaded rod 15 can drive the torsion spring 17 to rotate. When there is no wind to drive the optical cable 11 to move, the force of the torsion spring 17 can drive the threaded rod 15 to rotate in the opposite direction. The rotation of the threaded rod 15 can drive the lifting plate 14 to reset, and then drive the first pulley 12 to reset. The fixing strip 20 can provide stability for the movement of the lifting plate 14, and the fixing plate 16 can limit the fixing strip 20 and the threaded rod 15.

[0038] In summary, by setting up a protective box 10, optical cable 11, first pulley 12, second pulley 13, lifting plate 14, threaded rod 15, fixing plate 16, torsion spring 17, rotating column 18 and fixing bar 20, the optical cable 11 inside the protective box 10 can be extended when there is wind, thereby reducing the pulling force on the optical cable 11 outside the protective box 10. When there is no wind, the optical cable 11 can be automatically reset. It is convenient to use and has a simple structure.

[0039] like Figure 4 and Figure 5 As shown, a first limiting groove 22 is provided on the front and rear side walls of the two perforations 21, and a second limiting groove 23 is provided on the side of the front and rear side walls of the two perforations 21 that is close to the cavity of the protective box 10.

[0040] A telescopic column 26 is fixedly installed on the side wall of each of the two corresponding clamping plates 24 that are far apart from each other. A spring 27 is fixedly installed at the end of each of the two telescopic columns 26 that is far apart from each other. The other ends of the two springs 27 are fixedly installed in the cavities of the two corresponding first limiting grooves 22. A sealing plate 25 is fixedly installed on the side wall of each of the two corresponding clamping plates 24 that is far apart from each other. The sealing plate 25 is movably installed in the cavity of the corresponding second limiting groove 23.

[0041] In practical use, when the optical cable 11 is pulled by the wind, the optical cable 11 will swing. During the swinging process, the optical cable 11 can drive the clamp 24 to move. The rounded corners at both ends of the clamp 24 play a protective role for the optical cable 11. When the optical cable 11 swings to the other side, the force of the spring 27 can push the telescopic column 26 to drive the clamp 24 to reset. The sealing plate 25 can play a sealing role to prevent debris from entering the cavity of the protective box 10. The first limiting groove 22 and the second limiting groove 23 can both play a limiting role for the clamp 24.

[0042] In summary, by setting the perforation 21, the first limiting groove 22, the second limiting groove 23, the clamping plate 24, the sealing plate 25, the telescopic column 26 and the spring 27, the clamping plate 24 can protect the optical cable 11, the spring 27 can drive the clamping plate 24 to reset, and the sealing plate 25 can seal the cable. It is convenient to use and has a simple structure.
