Description

Technical Field

[0001] The invention relates to the technical field of turbine blade detection, and in particular to a communication optical cable rodent protection device. Background Art

[0002] Communication optical cable is a high-tech communication line that uses optical signals to transmit information. It is mainly composed of optical fibers and can transmit data at extremely high speeds and capacities. It has the advantages of anti-electromagnetic interference, long transmission distance, and good confidentiality. It is widely used in the Internet, telephone networks, and television signal transmission.

[0003] However, during the laying process of communication optical cables, they are often damaged by rats gnawing, resulting in signal transmission interruption, high maintenance costs and affecting the quality of communication services. Existing rodent-proofing measures have certain limitations, such as chemical agents may cause environmental pollution, physical protection is easily breached, and existing optical cable protective covers are not easy to remove and replace after laying. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and provide a communication optical cable rodent protection device.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: a communication optical cable rodent protection device, comprising:

[0006] optical fiber;

[0007] Support assembly; the support assembly comprises a non-metallic reinforcing core, the outer side of the non-metallic reinforcing core is fixedly connected to a cable core filler, the outer side of the cable core filler is fixedly connected to a pressure bag in a circular array, an extrusion bag is arranged on the outer side of the pressure bag, and the end of the extrusion bag away from the pressure bag is fixedly connected to aramid;

[0008] Protection component; the protection component comprises a metal protection shell 1 sleeved on the outside of the aramid fiber, one end of the metal protection shell 1 is rotatably connected to a rotating shaft, and the end of the rotating shaft away from the metal protection shell 1 is rotatably connected to a metal protection shell 2;

[0009] Rat repellent assembly; the rat repellent assembly includes an inner ring fixedly connected to the inside of metal protective shell one and metal protective shell two, an air bag is fixedly connected to the outside of the inner ring, an inner repellent layer is fixedly connected to the inside of metal protective shell one and the rotating shaft, and an outer repellent layer is fixedly connected to the end of the air bag away from the inner ring.

[0010] The technical effect of adopting the above technical solution is: by providing a non-metallic reinforcing core and a cable core filler, the communication optical cable rodent-proof protection device of the present invention can provide sufficient mechanical strength while maintaining the flexibility of the optical cable, ensuring that the optical cable will not be easily broken when subjected to external force. The design of the pressure capsule and the extrusion capsule enables the device to evenly disperse the pressure when subjected to pressure, avoiding damage to the optical cable caused by excessive local force.

[0011] The setting of the first and second metal protective shells not only enhances the physical protection capability of the optical cable, but also enables the protective shells to rotate flexibly through the connection of the shaft to adapt to different laying environments. The use of aramid further improves the tensile strength and impact resistance of the device.

[0012] The setting of the rat repellent component can effectively repel rats and prevent them from approaching the optical cable through the cooperation of the inner repellent layer and the outer repellent layer, as well as the assistance of the airbag. The inner repellent layer and the outer repellent layer can be materials with rat repellent properties, such as materials with special smells or devices that can emit rat repellent sound waves, and the airbag can expand rapidly when bitten by rats to form a physical barrier, further preventing the rats from destroying the cable.

[0013] As a preferred embodiment, an installation and disassembly component; the installation and disassembly component includes a slot opened on the two ends of the outer side of the metal protective shell 2, the two ends of the outer side of the metal protective shell 1 are fixedly connected with straps, the inside of the strap is provided with a fault-tolerant slide groove, the outer side of the fault-tolerant slide groove is slidably connected with a connecting column, the bottom end of the connecting column is fixedly connected with a card column, and the two ends of the outer side of the card column are fixedly connected with limiting columns.

[0014] The technical effect of adopting the above technical solution is that the installation and removal process is more convenient and efficient. The cooperation between the card slot and the card column enables the device to be quickly fixed on the optical cable.

[0015] As a preferred implementation, a limiting groove is provided inside the slot, the outer side of the limiting column is slidably connected to the fault-tolerant sliding groove, and the outer side of the limiting column is slidably connected to the limiting groove.

[0016] The technical effect of adopting the above technical solution is to ensure that the limit column can be accurately positioned at the predetermined position during the installation process, thereby ensuring the stability and reliability of the device. The design of the limit groove enables the limit column to effectively limit its range of movement when subjected to external force, preventing damage to the device caused by excessive sliding. In practical applications, users can quickly and accurately complete the installation and removal of the device without complex tools or expertise, greatly reducing maintenance costs and time consumption.

[0017] As a preferred implementation, a pressure spring is sleeved on the outer side of the clamping column, and an operating handle is fixedly connected to the top end of the connecting column.

[0018] The technical effect of adopting the above technical solution is that the pressure spring can provide continuous elastic force for the card column, ensuring close contact between the card column and the card slot, thereby enhancing the fixing effect of the device and preventing loosening in the event of vibration or impact.

[0019] As a preferred implementation, one end of the pressure spring is fixedly connected to the operating handle, and one end of the pressure spring away from the operating handle is fixedly connected to the binding strap.

[0020] The technical effect of adopting the above technical solution is: the setting of the operating handle allows the user to easily apply force when installing or removing the protective device, thereby quickly adjusting the strap; secondly, the design of the pressure spring can ensure stability after installation and avoid misalignment that may cause installation failure.

[0021] As a preferred embodiment, the interior of the second metal protective shell is sleeved on the outer side of the aramid.

[0022] The technical effect of adopting the above technical solution is that the entire anti-rat protection device can provide a more solid protection layer when facing the gnawing of rodents.

[0023] As a preferred embodiment, the inner repellent layer is made of cinnamamide, and the outer repellent layer is made of capsaicin.

[0024] The technical effect of adopting the above technical solution is: it can not only effectively protect the communication optical cable from rodent damage, but also because of the use of natural repellent ingredients, it is environmentally friendly and will not cause harm to plants and animals near the optical cable.

[0025] As a preferred embodiment, the outer side of the optical fiber is clamped by a pressure bag squeezing the squeezing bag.

[0026] The technical effect of adopting the above technical solution is that the optical fiber can be additionally protected when subjected to external force, and the elastic characteristics of the pressure bag can absorb part of the impact force, thereby reducing the direct pressure on the optical fiber and extending the service life of the optical fiber.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are

[0028] By passing the optical fiber through the support component, the outer side of the optical fiber is ensured to be squeezed by the pressure bag to squeeze the aramid fiber to provide mechanical strength and environmental resistance to prevent damage to the optical cable. Then, the protective component is placed on the outside of the aramid fiber, and the metal protective shell is connected by a shaft to form a rotatable protective layer to effectively prevent rat bites and external damage; this design can effectively and firmly fix the optical cable to ensure its stability and safety. The buffer layer equipped with the optical cable fixing frame has multiple functions. It can not only absorb the impact force from the outside, thereby protecting the optical cable from accidental damage, but also effectively fill the gap between the optical cable and the fixing frame to ensure that the optical cable will not be worn or broken due to vibration or movement during operation.

[0029] Move the strap to the slot, press to slide the limit post into the fault-tolerant slot, rotate to fix the limit post in the limit slot, and the post is stuck in the slot. At this time, the pressure spring is compressed to prevent the limit post from moving excessively. This design ensures that the optical cable can be effectively physically protected when it is threatened by the bite of mice and other animals. The firmness of the metal shell effectively prevents damage from rodents. At the same time, the rotating structure allows the protective shell to be flexibly installed and disassembled, avoiding the traditional protective shell that cannot be easily disassembled and replaced, or during the maintenance process, there is no need to disassemble the entire optical cable protection system on a large scale, reducing the complexity and workload of maintenance work, and further improving maintenance efficiency.

[0030] The airbag is designed to form a certain space outside the optical cable to facilitate the release of the rat repellent. When the airbag is damaged, the insect repellent inside can be quickly released to produce an effective rat repellent effect. The inner repellent layer and the outer repellent layer are made of cinnamamide and capsaicin respectively. These substances strongly force mice to stay away from the optical cable by releasing the rat repellent smell for a long time, reducing the risk of the optical cable being bitten; this design realizes that the inner repellent layer and the outer repellent layer use different rat repellent ingredients to enhance the rat repellent effect and effectively prevent mice from gnawing the optical cable. When the spare airbag is broken, the internal insect repellent will be automatically released to quickly play a role in expelling mice. This will not only more effectively prevent mice from gnawing, but also its agent release mechanism is automatic, avoiding human intervention. BRIEF DESCRIPTION OF THE DRAWINGS

When the pressure capsule 23 and the extrusion capsule 24 are protected, the pressure capsule 23 and the extrusion capsule 24 can be pressed against each other when the extrusion capsule 24 is pressurized. In this way, 1 can be stably installed on the cable core filler 22 to prevent displacement. The aramid fiber 25 is used to improve the mechanical strength and environmental resistance of the optical cable. Especially in the large-span optical cable, the aramid fiber 25 can not produce creep for a long time, which significantly increases the service life of the optical cable.

[0050] The card slots 41 are provided at both ends of the outer side of the metal protective shell 33 to fix and stabilize the binding belt 42, so as to ensure that the optical cable can be firmly fixed in place after installation. The binding belt 42 is fixedly connected to both ends of the outer side of the metal protective shell 31 to bundle and fix the optical cable. The binding effect of the binding belt 42 can conveniently fix the optical cable in the desired position. At the same time, the adjustability of the binding belt 42 also makes the installation process more flexible. The fault-tolerant slide groove 43 is provided inside the binding belt 42 to allow the connecting column 44 to slide thereon for easy disassembly and installation. The connecting column 44 is slidably connected to the fault-tolerant slide groove 43, and a card column 45 is fixedly connected to the bottom end to fix the binding belt 42 in the card slot 41. , can realize the fixing and releasing of the binding belt 42, convenient for the installation and removal of the optical cable, the clamping column 45 is used to fix the binding belt 42 in the clamping slot 41, to ensure that the binding belt 42 will not slide or fall off in the clamping slot 41, the limiting column 46 is fixedly connected to the outer ends of the clamping column 45, and is slidably connected to the fault-tolerant sliding groove 43 and the limiting groove 49, to limit the movement range of the binding belt 42, the limiting groove 49 is arranged inside the clamping slot 41, to limit the sliding of the limiting column 46, to ensure that the binding belt 42 is fixed in the correct position, the design of the pressure spring 47 ensures that the optical cable can be stably fixed in various environments through elastic action, and the design of the operating handle 48 allows the user to easily adjust the installation and removal component 4, to ensure the convenience of operation;

[0053] Working principle:

[0054] like Figure 1 - Figure 6 As shown:

[0055] When in use: First, pass the optical fiber 1 through the support assembly 2, and ensure that the outer side of the optical fiber 1 is squeezed by the pressure bag 23 to engage with the aramid 25, so that when the optical fiber 1 is subjected to external pressure, the aramid 25 can provide sufficient mechanical strength and environmental resistance to prevent damage to the optical cable, and then the protective assembly 3 is set on the outer side of the aramid 25, and the metal protective shell 1 31 and the metal protective shell 2 33 are connected by the rotating shaft 32 to form a rotatable protective layer, which effectively prevents rodents from gnawing and external damage;

[0056] Then, the operating handle 48 is held and the strap 42 is moved toward the card slot 41. When the card slot 41 contacts the card column 45, the limiting column 46 is pressed downward to slide on the fault-tolerant slide slot 43 and slide toward the limiting slot 49. Then, the operating handle 48 is rotated to rotate the limiting column 46 on the limiting slot 49, and the protruding portion at the top of the card slot 41 can clamp the card column 45 in the card slot 41. At this time, the pressure spring 47 is compressed and moves toward the top to avoid the deviation caused by excessive movement of the limiting column 46.

[0057] And due to the design of the inner repellent layer 53 and the outer repellent layer 54, it can have the effect of repelling rats within a certain period of time. If a rat bites through the metal protective shell 1 31 or the metal protective shell 2 33, the airbag 52 will release the rat repellent inside when it is damaged, thereby achieving the effect of double protection.
