Description

Technical Field

[0001] This invention belongs to the field of optical cable technology, specifically relating to a buried anti-biting optical cable and its usage method. Background Technology

[0002] Many fiber optic cables are laid in remote, undeveloped areas, making them vulnerable to gnaw by birds and rodents. Existing fiber optic cables have an outer sheath made of polyethylene, which has low hardness and is easily chewed through, affecting the cable's tensile strength and making the internal optical fibers prone to breakage, leading to communication interruptions. Current methods to prevent gnaw damage typically involve adding pungent substances to the outer sheath material using chemical methods. However, the pungent smell fades over time, and the effect usually fails after six months. Therefore, there is an urgent need to develop a fiber optic cable that can provide long-term protection against birds and rodents.

[0003] Chinese patent CN205942033U, entitled "Anti-bite Optical Cable," discloses a cable core composed of at least two twisted optical fibers; a reinforcing wire located in the middle of the cable core; an outer sheath covering the outer side of the cable core; the outer surface of the outer sheath having a dense array of protrusions and a colored coating; and a metal internal reinforcing layer between the outer sheath and the cable core. This patent uses dense protrusions and a colored coating on the outer surface of the sheath to mimic the posture of a snake, deterring birds and rodents and providing a biting-resistant effect from a biomimetic perspective. Furthermore, the metal internal reinforcing layer increases the cable's strength, thus ensuring the reliability of optical cable communication. However, the above-mentioned patent still has the following problems: once rodents and other creatures adapt to the shape and color of the optical cable, they may still gnaw on it. Although the internal metal reinforcement layer can play a certain protective role, the strength of the optical cable at the damaged point will be reduced due to the damage to the outer sheath, and over time it will still lead to damage to the damaged part of the optical cable. Summary of the Invention

[0004] To address the technical problems existing in the prior art, the purpose of this invention is to provide a buried anti-bite optical cable and its usage method.

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

[0006] A buried anti-bite optical cable includes an optical cable core, an inner reinforcing layer, and an outer sheath arranged sequentially from the inside out. Multiple support blocks are arranged between the inner reinforcing layer and the outer sheath, forming a space between the inner reinforcing layer and the outer sheath. The space is filled with anti-bite material, and anti-bite components are installed on the outer sheath for alarm functions and / or for adding anti-bite material into the space.

[0007] Furthermore, the optical cable core includes reinforcing ribs and a plurality of cable cores evenly distributed on its exterior, and the cable cores are covered with an internal reinforcing layer.

[0008] Furthermore, the reinforcing rib is located at the center of the optical cable core.

[0009] Furthermore, multiple through-holes are evenly distributed between the inner reinforcing layer and the outer sheath, and support blocks are provided on the through-holes. The support blocks are evenly distributed along the circumferential direction between the inner reinforcing layer and the outer sheath, and the support blocks are made of rubber.

[0010] Furthermore, the anti-biting component includes a filling cylinder mounted on an outer sheath. A piston is slidably installed inside the filling cylinder, and an insert rod is mounted on the piston. A gripping ball is mounted on the insert rod. A spring is also installed inside the filling cylinder, with its lower end connected to the piston. The spring is sleeved on the insert rod. A one-way tube is installed on the filling cylinder, and the two communicate with the space formed between the inner reinforcing layer and the outer sheath. A sealing cap is screwed onto the one-way tube and engaged with it.

[0011] Furthermore, a first electrode is installed on the holding ball, and a second electrode is installed below the first electrode and on the filling cylinder. The first electrode and the second electrode can be in contact or separated.

[0012] This invention also discloses a method for using buried anti-bite optical cable, comprising the following steps:

[0013] First, the optical cable core is prepared, and then an internal reinforcing layer is set on its exterior. The support block is installed in the through slot of the outer sheath and arranged as a whole outside the internal reinforcing layer, forming a space between the internal reinforcing layer and the outer sheath. Then, the space formed between the internal reinforcing layer and the outer sheath is filled with pungent or irritating substances using the following steps: the one-way tube is connected to the filling container, the holding ball is pulled outward, and the piston moves outward, so that the pungent or irritating substances in the filling container enter the space formed between the internal reinforcing layer and the outer sheath under pressure through the one-way tube and the filling cylinder. After filling, it is buried underground.

[0014] When a mouse or other creature bites through the outer sheath, pungent or irritating substances leak out, stimulating the mouse or other creature and causing them to stop biting. Simultaneously, due to the leakage, the piston moves inward under the action of a spring, causing electrode one to contact electrode two. Since a controller is connected to electrode one and electrode two, the contact between them generates an electrical signal change, triggering an alarm for timely maintenance. Electrodes one and two can be connected to the input terminal of a controller (PLC, etc.), which can sense changes in signal level. This can be achieved by sensing high or low levels of the signal. Those skilled in the art can refer to existing technology that generates electrical signal changes through switching on and off, which will not be elaborated upon here.

[0015] When adding pungent or irritating substances, connect the one-way tube to the addition container, pull the ball outward to move the piston outward, and the pungent or irritating substance in the addition container will enter the outer sheath through the one-way tube and the filling tube. The operation is simple and efficient, and helps to ensure the long-term effectiveness of the anti-bite performance.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention discloses a buried anti-bite optical cable and its usage method. The optical cable includes an optical cable core, an inner reinforcing layer, and an outer sheath arranged sequentially from the inside out. Multiple support blocks are disposed between the inner reinforcing layer and the outer sheath, forming a space filled with an anti-bite substance. An anti-bite component is installed on the outer sheath for alarm functions and / or adding anti-bite substance to the space. The buried anti-bite optical cable provided by this invention can achieve alarm functions and / or add anti-bite substance through the anti-bite component, facilitating timely maintenance by repair personnel. It also allows for timely and rapid addition of anti-bite substance, ensuring the long-term effectiveness of the cable's anti-bite capability. The anti-bite effect is significant, guaranteeing the reliability of optical cable communication. The overall structure is reasonable, novel, and low-cost, making it suitable for industrial-scale promotion and use. Attached Figure Description

[0019] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0020] The present invention will now be described in detail so that its advantages and features can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0021] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0022] like Figure 1-2 As shown, a buried anti-bite optical cable includes a reinforcing rib 1 located in the center. Multiple cable cores 2 are evenly arranged around the reinforcing rib 1. Each cable core 2 is composed of at least two stranded optical fibers. Optical fiber products are readily available on the market. The reinforcing rib 1 and the multiple cable cores 2 constitute the optical cable core. An inner reinforcing layer 3 is wrapped around the optical cable core. The inner reinforcing layer 3 is made of metal or rubber. An outer sheath 5 is provided outside the inner reinforcing layer 3, and multiple ring-shaped support blocks 4, made of rubber, are provided between the two. The support blocks 4 mainly support the outer sheath 5, creating a space between the outer sheath 5 and the inner reinforcing layer 3. This space is filled with an anti-bite substance (a pungent or irritating substance). An injection cylinder 6 is installed on the outer sheath 5, extending along the length of the outer sheath 5, and spaced apart at intervals of two segments. At least one filling cylinder 6 is provided between the plates 16. A piston 7 is slidably installed inside the filling cylinder 6. An insertion rod 8 is installed on the piston 7. A holding ball 9 is installed on the insertion rod 8. An electrode 10 is installed on the holding ball 9. A second electrode 11 is installed below the first electrode 10 and on the filling cylinder 6. A one-way tube 12 is installed on the filling cylinder 6. It is a tubular structure with an internal one-way valve (similar to the structure of a heart valve) to allow inward flow and outward cut-off. It can be replaced by a one-way valve. A sealing cap 13 is screwed onto the one-way tube 12. A spring 14 is installed inside the filling cylinder 6. The lower end of the spring 14 is connected to the piston 7. The spring 14 is sleeved on the insertion rod 8. The filling cylinder 6 and the one-way tube 12 are connected to the space formed between the outer sheath 5 and the inner reinforcing layer 3, which facilitates the addition of anti-biting material into the space through the filling cylinder 6 and the one-way tube 12.

[0023] In this invention, the segment partition 16 is set between the inner reinforcing layer 3 and the outer sheath 5 to separate the support block 4. The entire optical cable can be divided into multiple segments by the segment partition 16. When one segment is bitten, it does not affect the operation of other segments. Only the segment needs to be repaired and anti-bite material added.

[0024] Multiple permeable grooves 15 are evenly distributed between the inner reinforcing layer 3 and the outer sheath 5. The support block 4 is installed in the permeable groove 15. The permeable groove 15 allows the passage of biting material, so that the space between the outer sheath 5 and the inner reinforcing layer 3 is filled with anti-biting material.

[0025] The method of using the buried anti-biting optical cable of the present invention includes the following steps:

[0026] First, the optical cable core is prepared, and then an internal reinforcing layer 3 is set on its exterior. The support block 4 is installed in the through slot 15 of the outer sheath 5 and arranged as a whole outside the internal reinforcing layer 3, forming a space between the internal reinforcing layer 3 and the outer sheath 5. Then, the space formed between the internal reinforcing layer 3 and the outer sheath 5 is filled with pungent or irritating substances using the following steps: the one-way tube 12 is connected to the addition container, the holding ball 9 is pulled outward, causing the piston 7 to move outward, thereby allowing the pungent or irritating substances in the addition container to enter the space formed between the internal reinforcing layer 3 and the outer sheath 5 under pressure through the one-way tube 12 and the filling cylinder 6. After the filling is completed, it is buried underground.

[0027] When a mouse or other creature bites through the outer sheath 5, pungent or irritating substances leak out, stimulating the mouse or other creature and causing them to stop biting. At the same time, due to the leakage of substances, the piston 7 moves inward under the action of the spring 14, thereby causing the first electrode 10 to contact the second electrode 11. Since a controller or similar device is connected to the first electrode 10 and the second electrode 11, the contact between the first electrode 10 and the second electrode 11 can generate an electrical signal change, triggering an alarm, which is convenient for maintenance personnel to perform timely repairs. For example, the first electrode 10 and the second electrode 11 can be connected to the input terminal of a controller (PLC, etc.). The input terminal of the controller can sense changes in the signal level. By sensing the signal change through high or low level, those skilled in the art can refer to the technology of generating electrical signal changes through switching, which is existing technology and will not be described in detail here.

[0028] When it is necessary to add spicy or irritating substances, connect the one-way tube 12 to the addition container, pull the holding ball 9 outward, and the piston 7 will move outward. This allows the spicy or irritating substances in the addition container to enter the outer sheath 5 through the one-way tube 12 and the filling cylinder 6. The operation is simple and efficient, and it helps to ensure the long-term effectiveness of the anti-bite performance.

[0029] Any parts or structures not specifically described in this invention can be made using existing technologies or products, and will not be elaborated upon here.

[0030] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
