[0002] Optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fiber and plastic protective casing and plastic outer skin. There is no gold, silver, copper, aluminum or other metals in the optical cable, and it generally has no recycling value. Optical cable is a communication line in which a certain number of optical fibers are arranged in a certain way to form a cable core, which is covered with a sheath and some are also covered with an outer sheath to realize the transmission of optical signals. Optical cable is not affected by electromagnetic interference and radio frequency interference, and optical cable can achieve long-distance transmission, which enables optical cable to be used in some harsh environments or complex environments.

[0003] However, after long-term use in some harsh environments, optical cables will experience a certain degree of corrosion, which will accelerate the aging rate of materials such as the plastic protective sheath outside the optical cable, thereby increasing the attenuation of the optical fiber inside the optical cable, causing damage to the optical cable, affecting the use effect and life of the optical cable. In view of this, the present invention is specially proposed. Summary of the invention

[0015] Compared with the prior art, the present invention provides an outdoor high-durability optical cable, which has the following beneficial effects: 1. For this outdoor high-durability optical cable, when the optical cable shakes in a harsh environment, the installation ring will drive the flexible optical rod to move, thereby driving the piston in the cylinder to move. When the piston moves, the cylinder can extract the gas between the inner sleeve and the outer sleeve. As the gas decreases, on the one hand, the connection effect between the semicircular airbag and the inner sleeve can be enhanced, ensuring the sealing between the inner sleeve and the outer sleeve and improving the protection effect. On the other hand, reducing the air can reduce the contact between the air and the inner sleeve and the outer sleeve, further improving the corrosion resistance effect, thereby enhancing the durability of the optical cable, and the extracted gas will be transported to the semicircular airbag, thereby expanding the semicircular airbag, further enhancing the sealing effect and stability between the outer sleeve and the inner sleeve, and the excess gas will enter the annular airbag, thereby expanding the annular airbag, improving the sealing performance and stability between the annular airbag and the protective cover.

[0016] 2. The outdoor high-durability optical cable can fix multiple protective covers together through the buckling grooves, so that multiple optical fiber components are tightly fixed and connected to each other, improving the connectivity between each other. Slight movement or vibration between optical fiber components may cause the optical signal to attenuate during transmission; by fixing multiple optical fiber components, such slight movement or vibration can be significantly reduced, thereby reducing signal attenuation and ensuring stable transmission of optical signals, thereby improving stability and reliability and enhancing durability.

[0017] 3. When installing the outer sleeve of the outdoor high-durability optical cable, the hollow rod is inserted into the cylinder, which will press the slide plate and the partition to move, so that the circular hole on the partition plate corresponds to the position of the delivery pipe, so that the gas in the delivery pipe can be transported to the cylinder through the circular hole, and then enter the hollow rod through the through hole on the slide plate, and then enter the annular airbag, so that the annular airbag expands, improves the sealing performance and stability between the annular airbag and the protective cover, and improves durability.

[0018] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. In the present invention, the durability of the optical cable in harsh environments can be improved, the corrosion resistance can be improved, damage to the optical cable can be avoided, and the use effect and service life of the optical cable can be guaranteed.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Example 1: Reference Figure 1-Figure 10A highly durable outdoor optical cable comprises a plurality of optical fiber components 1, and a plurality of protective sleeves 101, which are respectively wrapped around the outer walls of the plurality of optical fiber components 1; and an inner sleeve 2 wrapped around the outer walls of the plurality of optical fiber components 1, the inner wall of the inner sleeve 2 being provided with a plurality of annular airbag components 201 which abut against the protective sleeves 101; an outer sleeve 3 is also provided, and semicircular airbag components 305 are provided at both ends of the inner wall of the outer sleeve 3, and the two semicircular airbag components 305 are respectively wrapped around the two ends of the inner sleeve 2; a cylinder 5 is provided on the outer wall of the outer sleeve 3, and the cylinder 5 is respectively connected with the two semicircular airbag components 305; a mounting ring 4 is slidably provided on the outer wall of the inner sleeve 2, a flexible optical rod 403 is provided on the mounting ring 4, a piston 502 is provided on the flexible optical rod 403, and the piston 502 is slidably connected in the cylinder 5.

[0024] In this embodiment, when in use, the inner sleeve 2 is first sleeved on the outer wall of the plurality of optical fiber components 1, and then the two outer sleeves 3 are mutually buckled and connected to the outer wall of the inner sleeve 2. After installation, the semicircular airbag member 305 on the inner wall of the outer sleeve 3 is abutted against the outer wall of the inner sleeve 2, and then the mounting ring 4 is connected to a fixed building, thereby realizing the positioning of the optical fiber component 1. The inner sleeve 2 and the outer sleeve 3 are provided to provide multi-layer protection for the optical fiber component 1, thereby improving the high temperature resistance and corrosion resistance of the optical fiber component 1 during use, and improving the durability.

[0025] During use, if strong wind or external force occurs and the mounting ring 4 is slidably connected to the inner sleeve 2, the optical fiber assembly 1 will shake or sway. When shaking, the mounting ring 4 will drive the flexible optical rod 403 to move, thereby driving the piston 502 located in the cylinder 5 to move. When the piston 502 moves, the cylinder 5 can extract the gas between the inner sleeve 2 and the outer sleeve 3, and a sealed cavity can be formed by the two semicircular airbags 305, the inner sleeve 2 and the outer sleeve 3. As the gas inside the cavity decreases, on the one hand, the connection effect between the semicircular airbag 305 and the inner sleeve 2 can be enhanced to ensure that the air is sealed. It ensures the sealing between the inner sleeve 2 and the outer sleeve 3 and improves the protective effect. On the other hand, reducing air can reduce the contact between the air and the inner sleeve 2 and the outer sleeve 3, further improving the corrosion resistance effect, thereby enhancing the durability of the optical cable, and the extracted gas will be transported to the semicircular airbag 305, so that the semicircular airbag 305 will expand, so that it will further enhance the sealing effect and stability between the outer sleeve 3 and the inner sleeve 2, and the excess gas will enter the annular airbag 201, so that the annular airbag 201 will expand, improve the sealing performance and stability between the annular airbag 201 and the protective cover 101, and improve the use effect.

[0026] During actual use, it is necessary to connect the inner sleeve 2 and the outer sleeve 3 on part of the optical cable that passes through a harsh environment. A mounting seat 313 is also provided at the tail of the inner sleeve 2 and the outer sleeve 3, which can enable multiple inner sleeves 2 and outer sleeves 3 to be interconnected to improve the use effect; and when in use, a corrosion-resistant and high-temperature resistant coating is applied on the protective sleeve 101, the inner sleeve 2 and the outer sleeve 3, so as to further achieve the effect of high temperature resistance and corrosion resistance.

[0027] The multiple protective covers 101 are respectively provided with snap-fitting grooves 102, and the multiple protective covers 101 are snapped together through the snap-fitting grooves 102. The multiple protective covers 101 can be fixedly connected to each other through the set snap-fitting grooves 102, so that the multiple optical fiber assemblies 1 are tightly fixedly connected to each other, thereby improving the connectivity between each other. Slight movement or vibration between the optical fiber assemblies 1 may cause the optical signal to attenuate during the transmission process; by fixing the multiple optical fiber assemblies 1, such slight movement or vibration can be significantly reduced, thereby reducing signal attenuation, ensuring the stable transmission of the optical signal, thereby improving stability and reliability, and enhancing durability.

[0028] A limiting groove 103 is provided on the outer side of the protective cover 101, and an extension portion 202 is provided on the annular airbag component 201. The extension portion 202 of the annular airbag component 201 is inserted into the limiting groove 103. The annular airbag component 201 can be set to fix a plurality of protective covers 101 in connection. The extension portion 202 on the annular airbag component 201 is inserted into the limiting groove 103, so that the annular airbag component 201 can limit a plurality of protective covers 101, making the connection tighter, further improving the stability and durability, and preventing the optical fiber assembly 1 from being damaged in harsh environments.

[0029] Example 2: Reference Figure 1-Figure 10 A highly durable outdoor optical cable comprises a plurality of optical fiber components 1, and a plurality of protective sleeves 101, which are respectively wrapped around the outer walls of the plurality of optical fiber components 1; and an inner sleeve 2 wrapped around the outer walls of the plurality of optical fiber components 1, the inner wall of the inner sleeve 2 being provided with a plurality of annular airbag components 201 which abut against the protective sleeves 101; an outer sleeve 3 is also provided, and semicircular airbag components 305 are provided at both ends of the inner wall of the outer sleeve 3, and the two semicircular airbag components 305 are respectively wrapped around the two ends of the inner sleeve 2; a cylinder 5 is provided on the outer wall of the outer sleeve 3, and the cylinder 5 is respectively connected with the two semicircular airbag components 305; a mounting ring 4 is slidably provided on the outer wall of the inner sleeve 2, a flexible optical rod 403 is provided on the mounting ring 4, a piston 502 is provided on the flexible optical rod 403, and the piston 502 is slidably connected in the cylinder 5.

[0030] There are two outer sleeves 3, both of which are semicircular. The two outer sleeves 3 are wrapped around the inner sleeve 2 after being buckled, and each outer sleeve 3 is provided with two semicircular airbag components 305. The semicircular airbag components 305 on the same side of the two outer sleeves 3 are against each other.

[0031] A hollow rod 203 is provided on the outer wall of the inner sleeve 2, and the hollow rod 203 is connected to the annular airbag component 201. A cylinder 306 is provided on the inner wall of the outer sleeve 3, and a slide plate 307 is slidably connected inside the cylinder 306. The slide plate 307 is provided with a through hole, and a delivery pipe 309 is provided between the semicircular airbag component 305 and the cylinder 306.

[0032] A partition 311 is provided on the slide plate 307, and the partition 311 is in contact with the inner wall of the cylinder 306. A circular hole 312 is provided on the partition plate 311. When the circular hole 312 moves to a position corresponding to the position of the delivery tube 309, the gas in the semicircular airbag part 305 can enter the cylinder 306 through the delivery tube 309. An elastic part 308 is provided between the slide plate 307 and the inner wall of the outer sleeve 3.

[0033] In this embodiment, refer to Figure 3 , Figure 8 , Fig. 9 and Fig.10When the optical cable shakes in a harsh environment, since the position of the mounting ring 4 is fixed, the piston 502 will be pulled back and forth to slide in the cylinder 5 under the action of the flexible light rod 403. If the piston 502 moves to the left in the cylinder 5, the right side will extract the gas between the inner sleeve 2 and the outer sleeve 3 through the right side exhaust pipe 504, so that the gas enters the right side of the piston 502. At this time, the gas on the left side of the piston 502 will be discharged through the exhaust pipe 503, so that it enters the semicircular airbag 30. 5, so that the semicircular airbag 305 is expanded, so that it further enhances the sealing effect and stability between the outer sleeve 3 and the inner sleeve 2. When the semicircular airbag 305 is expanded to the point where it cannot be expanded again, the excess gas will enter the delivery tube 309 and then enter the cylinder 306 again. Before this, when the outer sleeve 3 is installed, the cylinder 306 is made to correspond to the position of the hollow rod 203, and then the hollow rod 203 is inserted into the cylinder 306, which will press the slide plate 307 to move, so that it drives the partition 3 11 moves, so that the circular hole 312 on the partition 311 corresponds to the position of the delivery tube 309, so that the gas in the delivery tube 309 can be delivered to the cylinder 306 through the circular hole 312, and then enter the hollow rod 203 through the through hole on the slide plate 307, and then enter the annular airbag 201, so that the annular airbag 201 expands, improves the sealing performance and stability between the annular airbag 201 and the protective cover 101, and improves the use effect. When the gases are saturated, the excess gases can be discharged through the air release valve 310 on the outer sleeve 3, thereby preventing the semicircular airbag component 305 and the annular airbag component 201 from being damaged. After the annular airbag component 201 is expanded, the extension portion 202 thereon will also expand, thereby tightly abutting against the limiting groove 103 on the protective sleeve 101, thereby improving the connection effect with the protective sleeve 101 and enabling a better fixing effect between multiple protective sleeves 101, thereby fixing multiple optical fiber assemblies 1 to each other and improving durability.

[0034] When the piston 502 moves to the right in the cylinder 5, the air extraction pipe 504 on the left side extracts the gas between the inner sleeve 2 and the outer sleeve 3 and makes it enter the left side of the piston 502. The other operations are the same as above.

[0035] In the initial state, the partition 311 is against the delivery pipe 309, which can prevent the gas from flowing out of the delivery pipe 309 and prevent gas leakage. The elastic member 308 can make the slide plate 307 automatically reset after moving, which is convenient for repeated use. The elastic member 308 can specifically be a spring or a spring.

[0036] Two groups of air outlet pipes 503 and air extraction pipes 504 are provided on the cylinder 5, and the two groups of air outlet pipes 503 and air extraction pipes 504 are respectively placed at the two ends of the piston 502.

The two groups of air outlet pipes 503 and air extraction pipes 504 can respectively perform air collection operations on the two semicircular air bag components 305, which is convenient for use.

[0037] Both the air outlet pipe 503 and the air exhaust pipe 504 are provided with a one-way valve, the outer sleeve 3 is provided with a deflation valve 310, the deflation valve 310 is connected to the semicircular airbag part 305, and a limiting cylinder 501 is also provided on the outer wall of the cylinder 5, and the flexible light rod 403 is slidably connected in the limiting cylinder 501.

[0038] Specifically, one-way valves are provided on the air outlet pipe 503 and the air extraction pipe 504. When the gas in the cylinder 5 needs to be discharged, it will only be discharged through the air outlet pipe 503. At this time, the one-way valve on the air extraction pipe 504 can prevent the gas from being discharged through the air extraction pipe 504. When the gas needs to be extracted, the exhaust operation will only be performed through the air extraction pipe 504. At this time, the one-way valve on the air outlet pipe 503 can prevent the gas from being extracted through the air outlet pipe 503, thereby improving the overall use effect.

[0039] The flexible light rod 403 is configured as a smooth structure, which is slidably connected to the limiting cylinder 501, and a sealing gasket is provided at the limiting cylinder 501, which can improve the sealing performance between the flexible light rod 403 and the limiting cylinder 501 and avoid gas leakage in the cylinder body 5. Secondly, the flexible light rod 403 is configured to be flexible, can produce a certain bending effect, and has a small elastic force, which can produce a certain compensation effect when bending.
