Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, specifically to a bird-proof device for optical fiber communication. Background Technology

[0002] With the rapid development and expansion of fiber optic communication networks, optical cables are widely used in areas with high forest coverage and good ecological environment. However, the problem of optical cable damage caused by birds pecking at them is becoming increasingly prominent.

[0003] Currently, the main solutions to bird pecking problems fall into two categories: chemical protection and physical protection. Chemical protection is detrimental to ecological conservation and is generally not recommended. Physical protection includes enhancing the mechanical properties of optical cables and installing bird deterrent devices. Existing bird deterrent devices are mostly installed at the top of poles, while optical cables are usually suspended at the bottom, making it difficult to provide effective protection. Some bird-proof structures use metal materials such as wire mesh, which are heavy and inconvenient to install. Furthermore, existing bird deterrent devices rely on limited methods, allowing birds to easily adapt and making it difficult to achieve a long-lasting and effective protective effect.

[0004] Traditional optical fiber cables are widely used in outdoor communication line laying. Birds landing on and pecking at the cables are a significant factor affecting the safety of communication lines. Existing bird-repelling devices mainly use reflective bird deterrents, ultrasonic bird deterrents, or bird spikes. Most of these devices only have a single deterrent function and lack a multi-method coordination mechanism. When birds adapt to a single method, they cannot effectively prevent birds from landing and pecking. Furthermore, existing devices cannot provide buffering or length compensation when the optical fiber cable is subjected to external tension. In situations such as strong winds, icing, or accidental snagging, the optical fiber cable is prone to breakage or damage due to excessive instantaneous tension.

[0005] To address the aforementioned issues, we propose a bird-proof device for communication optical cables. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a bird-repelling device for communication optical cables. The device utilizes methyl anthranilate particles to emit an irritating odor to form a chemical repellent, red epoxy resin coating to provide a visual warning, and a repellent tip triggered by pressing the semi-circular shell to extend and form a physical repellent. The three repelling methods work synergistically and complement each other to avoid birds developing a single adaptation and to increase the bird-repelling effect of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bird-proof device for communication optical cables, comprising a lower semi-circular shell and an upper semi-circular shell rotatably mounted behind the lower semi-circular shell, wherein tensile protective components are provided on opposite sides of the bottom of the lower semi-circular shell. A feeding port is provided on the front side of the lower semi-circular shell, and a feeding cover is snapped into the inside of the feeding port. Several vent holes are provided on the lower side of the inner wall of the lower semi-circular shell. The top of the upper semi-circular shell is provided with a pressing semi-circular shell, and a number of connecting square rods are fixedly installed at the bottom of the pressing semi-circular shell. Telescopic combination cylinders are slidably installed on the lower side of the walls of the connecting square rods, and an unfolding protective component is provided at the bottom of the connecting square rods.

[0008] Furthermore, protective semicircular pads are fixedly installed inside both the lower and upper semicircular shells, and the protective semicircular pads are integrally formed from neoprene rubber.

[0009] Furthermore, the tensile protection component includes a U-shaped support frame fixedly installed on one side of the bottom of the lower semi-circular shell. A rotating groove is provided on the top side of the U-shaped support frame away from the lower semi-circular shell, and an arc-shaped interlocking groove is rotatably installed inside the rotating groove. A movable groove is provided on the lower side of the inner wall of the rotating groove. An adjusting screw is rotatably installed on the inner wall of the movable groove near the lower semi-circular shell. An adjusting groove block is threadedly connected to the rod wall of the adjusting screw. A first tension spring is rotatably installed on the inner wall of the adjusting groove block.

[0010] Furthermore, the arc-shaped interlocking groove has a concave arc-shaped groove surface at its arc position. The contour of the arc-shaped groove surface is adapted to the shape of the outer wall of the optical cable, which is used to embed the optical cable into the arc-shaped interlocking groove and form a fitting fit with the optical cable. One end of the adjusting screw extends through to the surface of the U-shaped support frame. The upper end of the first tension spring extends into the interior of the rotating groove through the moving groove, and the upper end of the first tension spring is fixedly connected to one side of the bottom of the arc-shaped interlocking groove. The connection position of the first tension spring and the arc-shaped interlocking groove is set away from the side of the lower semi-circular shell.

[0011] Furthermore, triangular reinforcing blocks are fixedly installed on the side of the U-shaped support frame near the arc-shaped interlocking groove and on the side of the inner surface of the U-shaped support frame near the lower semi-circular shell, respectively. There are two triangular reinforcing blocks inside the U-shaped support frame and one triangular reinforcing block near the lower semi-circular shell.

[0012] Furthermore, a combined horizontal plate is fixedly installed on the front side of both the lower and upper semi-circular shells, and the two combined horizontal plates are fixedly installed with screws to ensure the overall stability.

[0013] Furthermore, the interior of the lower semi-circular shell is filled with methyl anthranilate particles, and the outer surfaces of both the lower and upper semi-circular shells are coated with red epoxy resin paint.

[0014] Furthermore, the lower ends of several of the connecting square rods extend through to the interior of the upper semi-circular shell, and the bottoms of several of the telescopic combination cylinders are fixedly connected to the lower side of the inner wall of the upper semi-circular shell.

[0015] Furthermore, the unfolding protective assembly includes a sliding block fixedly installed at the bottom of the connecting square rod, and a compression activation rod is rotatably installed on both opposite sides of the sliding block. A compression movement port is opened on the surface of the telescopic combination cylinder on one side of the compression activation rod. The first combined rod is rotatably mounted on the side of the extrusion start rod away from the telescopic combined cylinder, and the second combined rod is rotatably mounted on the end of the first combined rod. A second tension spring is fixedly mounted between the first combined rod and the second combined rod. The upper side of the inner wall of the upper semi-circular shell and the surface of the pressing semi-circular shell are both provided with extension openings, and two expulsion tips are fixedly installed on the side of the second combined rod away from the first combined rod.

[0016] Furthermore, one end of the extrusion start rod extends into the interior of the upper semi-circular shell through the extrusion moving port, the bottom of the first combined rod is rotatably connected to the lower side of the interior of the upper semi-circular shell, the surface of the second combined rod slides in contact with the interior of the extension port on the upper semi-circular shell, and the surfaces of the two expulsion tips slide in contact with the interior of the extension port on the pressing semi-circular shell. When the semi-circular shell is pressed, the drive squeezing actuation rod squeezes the first combination rod, causing the first and second combination rods to unfold and push out the repelling point. The squeezing actuation rod is located below the first combination rod, which ensures that the squeezing actuation rod can push out the repelling point even with a small displacement, thus achieving the effect of repelling birds when they land. Furthermore, the dual repellency of extension and odor further avoids the impact of bird damage on the optical cable. The tensile protection component can greatly increase the safety of the optical cable and can compensate for the length when the optical cable is subjected to a large tensile force.

[0017] Compared with the prior art, the present invention provides a bird-proof device for communication optical cables, which has the following advantages: 1. This device utilizes methyl anthranilate particles to emit an irritating odor to form a chemical repellent, red epoxy resin coating to serve as a visual warning, and the repellent tip triggered by pressing the semi-circular shell to extend and form a physical repellent. The three repellent methods work together and complement each other to avoid birds developing a single adaptation and to increase the bird-repelling effect of the device.

[0018] 2. When the semi-circular shell is pressed, the device can drive the second combined rod to produce a large expansion displacement. After the bird flies away, the second tension spring drives the combined rod to reset, and the semi-circular shell is reset under the elastic action of the telescopic combined cylinder, realizing instantaneous triggering of the expulsion and self-recovery of the device.

[0019] 3. The device uses a tensile protection component. When the optical cable is under tension, the arc-shaped interlocking groove rotates around the rotating groove and pulls the first tension spring to generate an elastic reaction force for buffering and length compensation. The rotating adjusting screw drives the adjusting groove block to move along the moving groove to change the preload of the first tension spring and adapt to different optical cable tension requirements.

[0020] 4. The device uses triangular reinforcing blocks to enhance the structural strength of the U-shaped support frame, preventing it from deforming under frequent rotation or large tensile forces, and ensuring the long-term reliability of the tensile protection components. The device's protective semi-circular pads can prevent the optical cable from directly contacting the rigid shell and causing squeezing damage. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 9 This embodiment of a bird-proof device for communication optical cables includes a lower semi-circular shell 1 and an upper semi-circular shell 2 rotatably mounted behind the lower semi-circular shell 1. Protective semi-circular pads 101 are fixedly installed inside both the lower and upper semi-circular shells 1 and 2. The protective semi-circular pads 101 are integrally formed from neoprene rubber. Combined horizontal plates 201 are fixedly installed on the front sides of both the lower and upper semi-circular shells 1 and 2. The two combined horizontal plates 201 are fixedly installed together by screws to ensure overall stability. Tensile protective components 3 are provided on opposite sides of the bottom of the lower semi-circular shell 1. The interior of the lower semi-circular shell 1 is filled with methyl anthranilate particles. The outer surfaces of both the lower and upper semi-circular shells 1 and 2 are coated with red epoxy resin paint.

[0025] The tensile protection component 3 includes a U-shaped support frame 301 fixedly installed on one side of the bottom of the lower semi-circular shell 1. A rotating groove 302 is provided on the top side of the U-shaped support frame 301 away from the lower semi-circular shell 1. An arc-shaped interlocking groove 303 is rotatably installed inside the rotating groove 302. A movable groove 304 is provided on the lower side of the inner wall of the rotating groove 302. An adjusting screw 305 is rotatably installed on the inner wall of the movable groove 304 near the lower semi-circular shell 1. An adjusting groove block 306 is threadedly connected to the rod wall of the adjusting screw 305. A first tension spring 307 is rotatably installed on the inner wall of the adjusting groove block 306. The arc-shaped interlocking groove 303 has a concave arc-shaped groove surface at the arc position. The outline of the arc-shaped groove surface is adapted to the shape of the outer wall of the optical cable. It is used to embed the optical cable into the arc-shaped interlocking groove 303 and form an interlocking fit with the optical cable. One end of the adjusting screw 305 extends through to the surface of the U-shaped support frame 301. The upper end of the first tension spring 307 extends through the moving groove 304 to the interior of the rotating groove 302. The upper end of the first tension spring 307 is fixedly connected to one side of the bottom of the arc-shaped interlocking groove 303. The connection position of the first tension spring 307 and the arc-shaped interlocking groove 303 is set on the side away from the lower semi-circular shell 1. Triangular reinforcing blocks 3011 are fixedly installed on the side of the U-shaped support frame 301 near the arc-shaped interlocking groove 303 and on the side of the inner surface of the U-shaped support frame 301 near the lower semi-circular shell 1, respectively. There are two triangular reinforcing blocks 3011 inside the U-shaped support frame 301, and one triangular reinforcing block 3011 near the lower semi-circular shell 1. A feeding port 4 is provided on the front side of the lower semi-circular shell 1. A feeding cover 5 is snapped into the inside of the feeding port 4. Several vent holes 6 are provided on the lower side of the inner wall of the lower semi-circular shell 1. The top of the upper semi-circular shell 2 is provided with a pressing semi-circular shell 7. Several connecting square rods 8 are fixedly installed at the bottom of the pressing semi-circular shell 7. Telescopic combination cylinders 9 are slidably installed on the lower side of the walls of the several connecting square rods 8. The lower ends of the several connecting square rods 8 extend through to the interior of the upper semi-circular shell 2. The bottom of the several telescopic combination cylinders 9 are all fixedly connected to the lower side of the inner wall of the upper semi-circular shell 2. The bottom of the several connecting square rods 8 is provided with an unfolding protective component 10. The protective assembly 10 includes a sliding block 1001 fixedly installed at the bottom of the connecting square rod 8. A compression start rod 1002 is rotatably installed on both sides of the sliding block 1001. A compression moving port 1003 is opened on the surface of the telescopic combination cylinder 9 on one side of the compression start rod 1002. A first combined rod 1004 is rotatably mounted on the side of the compression start rod 1002 away from the telescopic combined cylinder 9. A second combined rod 1005 is rotatably mounted on the end of the first combined rod 1004. A second tension spring 1006 is fixedly mounted between the first combined rod 1004 and the second combined rod 1005. An extension opening 1007 is provided on the upper side of the inner wall of the upper semi-circular shell 2 and on the surface of the pressing semi-circular shell 7. Two expulsion tips 1008 are fixedly installed on the side of the second combined rod 1005 away from the first combined rod 1004. One end of the squeeze start rod 1002 extends into the interior of the upper semi-circular shell 2 through the squeeze moving port 1003. The bottom of the first combined rod 1004 is rotatably connected to the lower side of the interior of the upper semi-circular shell 2. The surface of the second combined rod 1005 slides in contact with the interior of the extension port 1007 on the upper semi-circular shell 2, while the surfaces of the two expulsion tips 1008 slide in contact with the interior of the extension port 1007 on the pressing semi-circular shell 7. When the semi-circular shell 7 is pressed, the drive squeezing actuation rod 1002 squeezes the first combination rod 1004, causing the first combination rod 1004 and the second combination rod 1005 to unfold, thereby pushing out the repelling tip 1008. The squeezing actuation rod 1002 is located below the first combination rod 1004, which ensures that the squeezing actuation rod 1002 can push out the repelling tip 1008 with a small pushing displacement, thus achieving the effect of repelling birds when they fall. Furthermore, by utilizing the dual repellency of extension and odor, the impact of bird damage on the optical cable is further avoided. The tensile protection component 3 can greatly increase the safety of the optical cable and can compensate for the length when the optical cable is subjected to a large tensile force.

[0026] The working principle of the above embodiments is as follows: When in use, the communication optical cable is first held together by the lower semi-circular shell 1 and the upper semi-circular shell 2, and then tightened with screws. In this way, the device enters a continuous protection state. Under normal conditions, the semi-circular shell 7 is pressed and held in its initial position by the elastic support of the telescopic combination cylinder 9. The repellent spike 1008 is stored in the extension port 1007 without affecting the normal transmission performance of the optical cable. Methyl anthranilate particles continuously emit an irritating odor through the vent 6 on the lower side of the inner wall of the lower semi-circular shell 1. Combined with the visual warning effect of the red epoxy resin coating on the outer surface of the lower semi-circular shell 1 and the upper semi-circular shell 2, it forms a continuous repellent effect on birds in the surrounding area, reducing the probability of birds landing on the surface of the device.

[0027] When a bird ignores olfactory and visual warnings and lands on the surface of the pressing semi-circular shell 7, the pressing semi-circular shell 7 moves downward under the pressure of the bird's weight. The pressing semi-circular shell 7 pushes the connecting square rod 8 to slide downward along the telescopic combination cylinder 9. The connecting square rod 8 drives the sliding block 1001 at its bottom to move downward in sync. The sliding block 1001 drives one end of the squeezing start rod 1002, which is rotatably installed on its opposite sides, to move downward.

[0028] The downward movement of the compression start rod 1002 compresses the first combined rod 1004. The contact position between the compression start rod 1002 and the first combined rod 1004 is located at the lower part of the first combined rod 1004, that is, near the bottom rotation fulcrum of the first combined rod 1004. In this way, when the driving force is applied to the position near the fulcrum, the end of the first combined rod 1004 obtains a large angular displacement amplification, so that the sliding block 1001 can drive the second combined rod 1005 to produce a large unfolding displacement with a small downward stroke.

[0029] After being pushed by the squeezing start rod 1002, the first combination rod 1004 rotates around its bottom fulcrum. The end of the first combination rod 1004 drives the second combination rod 1005, which is rotatably installed at its end, to unfold upward. The second combination rod 1005 drives the repulsion tip 1008, which is fixedly installed on the side away from the first combination rod 1004, to be pushed outward along the extension opening 1007 on the pressing semi-circular shell 7. After the repulsion tip 1008 extends out of the surface of the pressing semi-circular shell 7, it generates a pricking stimulation on the bird's foot, forcing the bird to fly away immediately, thus achieving an instantaneous response effect of the bird being driven away as soon as it lands.

[0030] After the bird flies away, the external force on the pressed semicircular shell 7 disappears. The first combined rod 1004 and the second combined rod 1005 retract under the elastic restoring force of the second tension spring 1006, which is fixedly installed between them. The pressed semicircular shell 7 returns to its original position under the elastic action of the telescopic combined cylinder 9. The expulsion point 1008 retracts into the extension port 1007. The device returns to its initial state and waits for the next trigger.

[0031] Throughout the protection process, the tensile protection component 3 works continuously to protect the optical cable from tensile damage. The optical cable is embedded in the arc-shaped splice groove 303 and forms a fitting fit with the arc-shaped splice groove 303 through the concave arc-shaped groove surface. When the optical cable is subjected to external tensile force, the optical cable drives the arc-shaped splice groove 303 to rotate around the rotating shaft of the rotating groove 302. When the arc-shaped splice groove 303 rotates, it pulls the first tension spring 307 fixedly connected to its upper end. After being stretched, the first tension spring 307 generates an elastic reaction force, which buffers and compensates for the tensile force on the optical cable, preventing the optical cable from breaking due to excessive instantaneous tensile force.

[0032] When the adjusting screw 305 is rotated, the adjusting screw 305 drives the threaded adjusting groove block 306 to move along the moving groove 304, changing the fixed position of the lower end of the first tension spring 307, thereby adjusting the initial tension and preload of the first tension spring 307 to adapt to the tension requirements of different optical cables. The triangular reinforcing block 3011 enhances the structural strength of the U-shaped support frame 301 and prevents the U-shaped support frame 301 from deforming during long-term use.

[0033] The odor repellent effect of the methyl anthranilate particles continuously emitted through the vent 6 in this application complements the physical repellent effect triggered by pressing the semi-circular shell 7 in both time and space. The odor repellent provides continuous protection against birds at a distance, while the physical repellent provides immediate protection after the birds break through the odor barrier. By combining the synergistic effects of odor repellent, visual warning, physical repellent, and tensile protection, comprehensive bird-pecking protection is achieved for communication optical cables.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
