Description

Technical Field

[0001] This utility model relates to the field of optical cable protection technology, specifically a protective device for stranded optical cables. Background Technology

[0002] Currently, with the rapid development of communication technology, optical cables, as an important carrier of information transmission, play a crucial role in the construction of communication networks. As a common type of optical cable, stranded optical cable is widely used in various communication lines due to its advantages such as compact structure and stable transmission performance.

[0003] In the process of laying and using optical cables, how to effectively protect them from damage by the external environment has become an urgent problem to be solved. Especially in complex environments such as roads and bridges, optical cables are often susceptible to damage from factors such as being run over by vehicles or being vandalized, which can lead to serious consequences such as cable breakage and signal transmission interruption.

[0004] Therefore, we propose a protective device for stranded optical cables that can adapt to different terrains and environmental conditions and has a high-efficiency protective effect. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for stranded optical cables, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for stranded optical cables, comprising a lower cover, wherein lower side plates are fixedly connected to both sides of the top of the lower cover, and positioning components are installed on the outer sides of both sets of lower side plates; an upper cover is provided at the top of the lower cover, and upper side plates are fixedly connected to both sides of the bottom of the upper cover; a supporting protective mechanism is fixedly installed on both sets of upper side plates, and the two sets of supporting protective mechanisms are respectively connected to the two sets of lower side plates.

[0007] Optionally, the support and protection mechanism includes multiple sets of equally spaced fixing blocks welded to the upper side plate, a piston rod fixedly installed at the bottom of each set of fixing blocks, a spring sleeved on the outer wall of each set of piston rods, an external thread opened at the bottom of each set of piston rods, and a nut threaded on each set of external threads. The top of each set of springs is fixedly installed to the side wall of the upper side plate.

[0008] By adopting the above technical solutions, optical cables can be protected.

[0009] Optionally, multiple sets of equidistantly distributed mating holes are provided on the inner side of the lower side plates on both sides. The multiple sets of mating holes are movably connected to the bottom of each set of piston rods, and the nuts of each set are distributed at the bottom of the two sets of lower side plates.

[0010] By adopting the above technical solution, the upper cover can be fixed.

[0011] Optionally, a baffle is fixedly installed at the top center of both sets of lower side plates, and each set of baffles is distributed on the insertion hole and docking hole bracket, with the baffles corresponding to the bottom of the upper side plate.

[0012] By adopting the above technical solution, the upper cover can be supported.

[0013] Optionally, the positioning component includes multiple sets of equally spaced insertion holes on the outer side of the lower side plate, a pin inserted into each set of insertion holes, a cone head fixedly connected to the bottom of each pin, and a stop block fixedly installed on the top of each set of pins.

[0014] By adopting the above technical solution, the lower cover can be positioned.

[0015] Optionally, adhesive pads are bonded to the center of both the lower and upper covers, and both sets of adhesive pads are in contact with the sidewall of the optical cable.

[0016] By adopting the above technical solution, the friction between the cover and the side wall of the optical cable is reduced.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application lays the optical cable inside the lower cover and installs an upper cover on top of the lower cover. Multiple sets of piston rods on the upper cover are connected to the docking holes on the lower cover. By tightening multiple sets of nuts at the bottom of each set of piston rods, the upper cover can be firmly fixed to the top of the lower cover. With the support of the springs on the outside of each set of piston rods, the upper cover can be supported on top of the optical cable. When the upper cover is subjected to road pressure, it will first squeeze the top of the optical cable, thus protecting the optical cable and preventing it from being damaged by long-term pressure.

[0019] Both lower side panels have baffles fixedly installed at the top center, corresponding to the bottom of the upper side panels. When the upper cover is subjected to strong road pressure, it will continuously compress the spring on the piston rod. When the spring's supporting force is insufficient to support the road pressure, the baffles fixedly installed on both sides of the top of the lower cover can support the upper side panels on both sides of the upper cover, preventing the upper cover from compressing the optical cable and further protecting the optical cable.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a protective device for stranded optical cables, including a lower cover 1, with lower side plates fixedly connected to both sides of the top of the lower cover 1, and positioning components installed on the outer sides of the two sets of lower side plates. An upper cover 21 is provided on the top of the lower cover 1, with upper side plates fixedly connected to both sides of the bottom of the upper cover 21, and supporting protective mechanisms fixedly installed on the two sets of upper side plates. The two sets of supporting protective mechanisms are respectively connected to the two sets of lower side plates. The supporting protective mechanism includes multiple sets of equally spaced fixing blocks 22 welded to the upper side plates, piston rods 23 fixedly installed at the bottom of each set of fixing blocks 22, springs 24 sleeved on the outer wall of each set of piston rods 23, external threads opened at the bottom of each set of piston rods 23, and nuts 3 threaded on each set of external threads. The top of each set of springs 24 is fixedly installed to the side wall of the upper side plate, which can protect the optical cable.

[0026] By laying the optical cable inside the lower cover 1 and installing the upper cover 21 on top of the lower cover 1, multiple sets of piston rods 23 on the upper cover 21 are connected to the docking holes 2 on the lower cover 1. By tightening multiple sets of nuts 3 at the bottom of each set of piston rods 23, the upper cover 21 can be firmly fixed to the top of the lower cover 1. With the support force of the springs 24 on the outside of each set of piston rods 23, the upper cover 21 can be supported on the top of the optical cable. When the upper cover 21 is subjected to the pressure of the road surface, it will first squeeze the top of the optical cable, thus protecting the optical cable and preventing it from being damaged by long-term pressure.

[0027] In this technical solution, baffles 31 are fixedly installed in the middle of the top of the two sets of lower side plates. Each set of baffles 31 is distributed on the bracket of the insertion hole 11 and the docking hole 2. The baffles 31 correspond to the bottom of the upper side plate and can support the upper cover 21.

[0028] When the upper cover 21 is subjected to strong pressure from the road surface, the upper cover 21 will continuously compress the spring 24 on the piston rod 23. When the supporting force of the spring 24 is insufficient to support the road surface pressure, the baffles 31 fixedly installed on both sides of the top of the lower cover 1 can support the upper side plates on both sides of the upper cover 21, preventing the upper cover 21 from compressing the optical cable and further protecting the optical cable.

[0029] In this technical solution, the positioning component includes multiple sets of equally spaced insertion holes 11 opened on the outer side of the lower side plate, a pin 12 inserted into each set of insertion holes 11, a cone head fixedly connected to the bottom of each pin 12, and a stop block fixedly installed on the top of each set of pins 12, which can position the lower cover 1.

[0030] By using the positioning components installed on both sides of the lower cover 1, each set of holes 11 can be inserted into the pins 12, and then each set of pins 12 can be hammered into the soil with a hammer, so that the lower cover 1 can be firmly fixed in the trench.

[0031] In this technical solution, both the lower cover 1 and the upper cover 21 have adhesive pads 32 bonded to their inner center. Both sets of adhesive pads 32 are in contact with the side wall of the optical cable to reduce friction between the cover and the side wall of the optical cable.

[0032] After the optical cable is laid inside the lower cover 1, the inner center of both the lower cover 1 and the upper cover 21 is bonded with a rubber pad 32, which can reduce the friction between the inner wall of the lower cover 1 and the upper cover 21 and the optical cable, and reduce the wear of the optical cable sheath.

[0033] In this technical solution, multiple sets of equidistantly distributed docking holes 2 are provided on the inner side of both lower side plates. The multiple sets of docking holes 2 are movably connected to the bottom of each set of piston rods 23. Each set of nuts 3 is distributed at the bottom of the two sets of lower side plates, which can fix the upper cover 21.

[0034] By connecting multiple sets of piston rods 23 on the upper cover 21 with the docking holes 2 on the lower cover 1, and by tightening multiple sets of nuts 3 at the bottom of each set of piston rods 23, the upper cover 21 can be firmly fixed to the top of the lower cover 1.

[0035] In use, first, an excavator digs a trench on the road, and then lays the lower cover 1 in the trench. Using the positioning components installed on both sides of the lower cover 1, each set of insertion holes 11 can be inserted into the pins 12. Then, a hammer is used to drive each set of pins 12 into the soil, firmly fixing the lower cover 1 in the trench. Simultaneously, the optical cable is laid inside the lower cover 1, and an upper cover 21 is installed on top of the lower cover 1. Multiple sets of piston rods 23 on the upper cover 21 align with the connecting holes 2 on the lower cover 1. Multiple sets of nuts 3 are then tightened onto the bottom of each set of piston rods 23, firmly fixing the upper cover 21 to the top of the lower cover 1. The supporting force of the springs 24 on the outer side of each set of piston rods 23 further supports the upper cover 21. At the top of the optical cable, after the upper cover 21 is subjected to pressure from the road surface, it will first squeeze the top of the optical cable to protect the optical cable and prevent it from being damaged by long-term pressure. At the same time, baffles 31 are fixedly installed in the middle of the top of the two sets of lower side plates. The baffles 31 correspond to the bottom of the upper side plates. When the upper cover 21 is subjected to strong pressure from the road surface, the upper cover 21 will continuously squeeze the spring 24 on the piston rod 23. When the supporting force of the spring 24 is insufficient to support the road surface pressure, the baffles 31 fixedly installed on both sides of the top of the lower cover 1 can support the upper side plates on both sides of the upper cover 21, preventing the upper cover 21 from squeezing the optical cable and further protecting the optical cable.
