Description

Technical Field

[0001] This invention relates to the field of butterfly optical cables, and particularly to a self-supporting corrosion-resistant butterfly optical cable. Background Technology

[0002] Currently, conventional self-supporting butterfly optical cables use metal reinforcements and low-smoke halogen-free flame-retardant polyolefin sheaths. The cable structure involves placing the optical fiber behind two parallel reinforcements and extruding a layer of LSZH or PVC sheath, while adding high-carbon steel wire or steel strand suspension wires. This provides tensile strength and is suitable for outdoor installation. However, in some special environments, due to the poor corrosion resistance of the optical cable itself, it is necessary to add conduits or other materials to the outside of the cable for additional protection. This significantly affects construction time and increases construction difficulty.

[0003] Therefore, it is necessary to propose a self-supporting corrosion-resistant butterfly optical cable to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a self-supporting, corrosion-resistant butterfly optical cable that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A self-supporting corrosion-resistant butterfly optical cable includes a first anti-corrosion sheath and a second anti-corrosion sheath. A through groove is provided in the center of the first anti-corrosion sheath, and a reinforcing suspension wire is installed in the inner cavity of the through groove. An optical fiber is installed in the inner cavity of the second anti-corrosion sheath.

[0007] The top and bottom of the through groove cavity are symmetrically and movably connected with reinforcing components. The first anti-corrosion sleeve and the second anti-corrosion sleeve are symmetrically and fixedly connected with a hanger on opposite sides. The bottom hanger cavity is movably connected with a movable column, and the top hanger bottom center is fixedly connected with a connecting column.

[0008] Preferably, a first flame-retardant braided layer is installed in the inner cavity of the first anti-corrosion sheath, separation grooves are symmetrically opened in the center of both sides of the second anti-corrosion sheath, a second flame-retardant braided layer is installed in the inner cavity of the second anti-corrosion sheath, and reinforcing members are symmetrically installed at the top and bottom of the inner cavity of the second flame-retardant braided layer.

[0009] Preferably, the outer wall of the optical fiber is fitted with a water-blocking layer, the outer wall of the water-blocking layer is fitted with a shaped armor, and the outer wall of the shaped armor is fitted with an electromagnetic shielding layer.

[0010] Preferably, the two reinforcing components are symmetrically attached to the top and bottom of the reinforcing suspension line on opposite sides, and springs are symmetrically fixedly connected to the center of the opposite sides of the two reinforcing components, with the other side of the springs fixedly connected to the inner cavity of the through groove.

[0011] Preferably, guide rods are symmetrically fixedly connected to the four sides of the two reinforcing components on opposite sides, and limit blocks are fixedly connected to the other side of the guide rods. The guide rods and limit blocks are interactively connected in the inner cavity of the first flame-retardant braided layer.

[0012] Preferably, a movable groove is provided in the center of the top of the bottom of the neck, and a limiting rod is fixedly connected to the center of the inner cavity of the movable groove. Strong springs are symmetrically wound on both sides of the outer wall of the limiting rod. The opposite sides of the two strong springs are symmetrically fixedly connected to the two sides of the inner cavity of the movable groove, and the opposite sides of the two strong springs are symmetrically fixedly connected to the two sides of the movable column.

[0013] Preferably, the movable column is movably connected to the inner cavity of the movable groove, the movable column is sleeved on the outer wall of the limiting rod, and the top of the front and back sides of the movable column are symmetrically provided with extrusion grooves. The inner cavity of the extrusion groove is fixedly connected to the limiting column, and the outer wall of the limiting column is wound with an extrusion spring. The top of the extrusion spring is fixedly connected to the top of the inner cavity of the extrusion groove.

[0014] Preferably, the top of the front and back sides of the inner cavity of the connecting column are symmetrically and movably connected to the inner cavities of the two extrusion grooves and sleeved on the outer wall of the limiting column, and the bottom of the extrusion spring is installed in the inner cavity of the connecting column. Beneficial effects

[0015] Compared with the prior art, the present invention provides a self-supporting corrosion-resistant butterfly optical cable, which has the following beneficial effects:

[0016] This self-supporting corrosion-resistant butterfly optical cable, through its first and second anti-corrosion sheaths, provides corrosion resistance to the optical fiber, ensuring the stability of signal transmission. The electromagnetic shielding layer provides electromagnetic shielding, while the shaped armor, reinforced suspension wires, second flame-retardant braided layer, and reinforcing components enhance tensile strength, withstand tension, and increase the internal corrosion resistance of the sheath. This reduces the impact of internal corrosion on signal transmission, improving the stability and lifespan of the optical fiber. This cable can be used independently in corrosive environments, and its manufacturing process effectively reduces installation and maintenance costs, ensuring the stability and sustainability of optical signal transmission in special environments.

[0017] This self-supporting corrosion-resistant butterfly optical cable, through the springs it is equipped with, can constantly push the reinforcing components outward, so that the top and bottom reinforcing components can always fit against the top and bottom of the reinforcing suspension line. When in use, the overall structure can be strengthened by the reinforcing suspension line, while also giving it a certain degree of mobility to facilitate position adjustment. Moreover, the position of the reinforcing components is adjustable, making it highly adaptable.

[0018] This self-supporting corrosion-resistant butterfly optical cable can be fitted onto the outer wall of the movable column through the set connecting post. After the second anti-corrosion sheath is compressed, the movable column can be moved to the bottom through the bottom hanger. At this time, the connecting post will move in the inner cavity of the extrusion groove and the outer wall of the limiting post, and compress the extrusion spring. At this time, the distance between the first and second anti-corrosion sheaths can be adjusted, which makes the installation more convenient.

[0019] This self-supporting corrosion-resistant butterfly optical cable, through the set movable groove and limiting rod, can move the first and second anti-corrosion sheaths left and right, which can further increase its installation range during installation. The set strong spring will squeeze the movable column when it moves, which can play a certain buffering effect. The set limiting rod can limit the movement of the movable column.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figure 1As shown, a self-supporting corrosion-resistant butterfly optical cable includes a first anti-corrosion sheath 1 and a second anti-corrosion sheath 6. A through groove 3 is opened in the center of the first anti-corrosion sheath 1, and a reinforcing suspension wire 4 is installed in the inner cavity of the through groove 3. An optical fiber 13 is installed in the inner cavity of the second anti-corrosion sheath 6. A first flame-retardant braided layer 2 is installed in the inner cavity of the first anti-corrosion sheath 1. Separation grooves 7 are symmetrically opened in the center of both sides of the second anti-corrosion sheath 6. A second flame-retardant braided layer 8 is installed in the inner cavity of the second anti-corrosion sheath 6. Reinforcing members 9 are symmetrically installed at the top and bottom of the inner cavity of the second flame-retardant braided layer 8. A water-blocking layer 12 is installed on the outer wall of the optical fiber 13. A special-shaped armor 11 is installed on the outer wall of the water-blocking layer 12. An electromagnetic shielding layer 10 is installed on the outer wall of the special-shaped armor 11.

[0027] The first anti-corrosion sheath 1 and the second anti-corrosion sheath 6 provide corrosion resistance to the optical fiber 13, thus ensuring the stability of signal transmission. The electromagnetic shielding layer 10 provides electromagnetic shielding to the optical fiber 13. The irregular armor 11, the suspension wire 4, the second flame-retardant braided layer 8, and the reinforcing member 9 enhance tensile strength, withstand tension, and increase the corrosion resistance inside the sheath. This reduces the impact of internal corrosion on signal transmission caused by the optical fiber 13, while also improving the stability and service life of the optical fiber 13. This optical cable can be used independently in corrosive environments, and its installation and maintenance costs can be effectively reduced during processing. It ensures the stability and sustainability of optical signal transmission in special environments.

[0028] like Figures 1-4As shown, a self-supporting corrosion-resistant butterfly optical cable has reinforcing components 14 symmetrically and movably connected to the top and bottom of the inner cavity of the through groove 3. A hanger 5 is symmetrically and fixedly connected to the opposite side of the first anti-corrosion sheath 1 and the second anti-corrosion sheath 6. A movable column 22 is movably connected to the inner cavity of the bottom hanger 5. A connecting column 21 is fixedly connected to the center of the bottom of the top hanger 5. The opposite sides of the two reinforcing components 14 are symmetrically attached to the top and bottom of the reinforcing suspension wire 4. A spring 15 is symmetrically and fixedly connected to the center of the opposite side of the two reinforcing components 14. The other side of the spring 15 is fixedly connected to the inner cavity of the through groove 3. Guide rods 16 are symmetrically and fixedly connected around the opposite side of the two reinforcing components 14. A limit block 17 is fixedly connected to the other side of the guide rod 16. The guide rod 16 and the limit block 17 are interactively connected to the inner cavity of the first flame-retardant braided layer 2. A movable groove 18 is opened in the center of the top of the bottom hanger 5. A limiting rod 19 is fixedly connected to the center of the inner cavity of the groove 18. A strong spring 20 is symmetrically wound on both sides of the outer wall of the limiting rod 19. The opposite sides of the two strong springs 20 are symmetrically fixedly connected to both sides of the inner cavity of the movable groove 18. The opposite sides of the two strong springs 20 are symmetrically fixedly connected to both sides of the movable column 22. The movable column 22 is movably connected in the inner cavity of the movable groove 18. The movable column 22 is sleeved on the outer wall of the limiting rod 19. The top of the front and back sides of the movable column 22 are symmetrically provided with extrusion grooves 23. A limiting column 24 is fixedly connected in the inner cavity of the extrusion groove 23. An extrusion spring 25 is wound on the outer wall of the limiting column 24. The top of the extrusion spring 25 is fixedly connected to the top of the inner cavity of the extrusion groove 23. The top of the front and back sides of the inner cavity of the connecting column 21 is symmetrically movably connected in the inner cavities of the two extrusion grooves 23 and sleeved on the outer wall of the limiting column 24. The bottom of the extrusion spring 25 is installed in the inner cavity of the connecting column 21.

[0029] The spring 15 allows the reinforcing component 14 to be constantly pushed outwards, ensuring that the top and bottom reinforcing components 14 are always in contact with the top and bottom of the reinforcing suspension line 4. During use, the reinforcing suspension line 4 strengthens the overall structure while providing some mobility for position adjustment. The position of the reinforcing component 14 is adjustable, offering high adaptability. The connecting post 21 can be fitted onto the outer wall of the movable post 22. When the second anti-corrosion sleeve 6 is compressed, the bottom hanger 5 can move the movable post 22 downwards, at which point the connecting post 21 will be in the compression groove 23. The inner cavity and the outer wall of the limiting post 24 move, and the compression spring 25 is compressed. At this time, the distance between the first anti-corrosion sleeve 1 and the second anti-corrosion sleeve 6 can be adjusted, which makes the installation more convenient. Through the set movable groove 18 and the limiting rod 19, the first anti-corrosion sleeve 1 and the second anti-corrosion sleeve 6 can be moved left and right, which can further improve the installation range during installation. Through the set strong spring 20, the movable post 22 will be compressed when it moves, which can play a certain buffering effect. And through the set limiting rod 19, the movement of the movable post 22 can be limited.

[0030] It should be noted that this invention is a self-supporting corrosion-resistant butterfly optical cable. In use, the two reinforcing components 14 are moved to opposite sides, and the reinforcing suspension wire 4 is installed in the inner cavity of the first anti-corrosion sheath 1 through the through groove 3. After releasing the reinforcing components 14, the spring 15 will spring the reinforcing components 14 inwards towards the through groove 3. At this time, the two reinforcing components 14 will fit against the top and bottom of the reinforcing suspension wire 4. The positions of the two suspension necks 5 are adjusted according to the installation positions of the first anti-corrosion sheath 1 and the second anti-corrosion sheath 6. Move the second anti-corrosion sleeve 6 to drive the movable column 22 to the bottom of the inner cavity of the connecting column 21. At this time, the inner cavity of the connecting column 21 will move in the inner cavity of the extrusion groove 23 and the outer wall of the limiting column 24, moving the bottom hanger 5 left and right. At this time, the movable column 22 will move in the inner cavity of the movable groove 18 and the outer wall of the limiting rod 19, and extrude and stretch the strong springs 20 on both sides. After moving to the appropriate position, the installation of the first anti-corrosion sleeve 1 and the second anti-corrosion sleeve 6 can be carried out.
