Description

Technical Field

[0001] This invention belongs to the field of optical fiber pipeline technology, specifically, it relates to an optical fiber pipeline with a corrugated section pressure-strengthening structure and its detection device. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that serves as a means of transmitting light. The fine fibers are encased in a plastic sheath, allowing them to bend without breaking. Typically, a transmitting device at one end of the fiber uses a light-emitting diode (LED) or a laser beam to transmit light pulses, while a receiving device at the other end uses a photosensitive element to detect the pulses. Because the transmission loss of light in optical fibers is much lower than that of electricity in wires, optical fibers are used for long-distance information transmission.

[0003] Chinese patent application CN106443923A discloses a crack-resistant fiber optic cable. Its wear-resistant layer design reduces friction damage during transportation, extending the cable's lifespan. Six fiber optic tubes are evenly distributed within the inner ring of the cable body, increasing fiber integration and significantly reducing production costs. Support rods connected to the outer walls of the fiber optic tubes allow for free expansion and contraction under tension and compression, ensuring the cable's cushioning performance. These rods, in conjunction with fixing rods, effectively prevent cracking. A moisture-proof layer absorbs moisture penetrating the cable, ensuring its dryness. Reinforcing ribs increase the overall cable's strength, and locking sleeves further enhance its crack resistance, significantly improving the practicality of the fiber optic cable.

[0004] However, this technical solution still has at least the following drawbacks: the optical fiber cable in this solution does not have a pressure-resistant structure, and when used for underground optical fiber burial, it cannot withstand the pressure caused by terrain deformation, resulting in easy damage to the optical fiber. In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an optical fiber duct with a corrugated section for enhanced compressive strength and a detection device thereof. By setting annular corrugations of different sizes on the optical fiber duct, its compressive strength is increased and its axial deformation is reduced. By setting helical corrugations at the ends, its torsional strength is enhanced, which facilitates connection with other ducts.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An optical fiber conduit with a corrugated section compression-strengthening structure includes a first corrugated section, a second corrugated section, and a third corrugated section. The second and third corrugated sections have different depths and are arranged alternately on the optical fiber conduit. The second and third corrugated sections are annular corrugations, while the third corrugated section is a spiral corrugation and is distributed at both ends of the optical fiber conduit. The depth of the second corrugated section is less than that of the third corrugated section. The second corrugated section reduces the overall deformation of the optical fiber conduit in the axial direction by reducing its depth, while the third corrugated section reduces the angle between two adjacent corrugated walls by increasing its depth.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0050] Example 1

[0051] like Figure 1 As shown, an optical fiber duct with a corrugated section compression-strengthening structure includes a first corrugated section 100, a second corrugated section 101, and a third corrugated section 102. The second corrugated section 101 and the third corrugated section 102 have different depths and are arranged alternately on the optical fiber duct. The second corrugated section 101 and the third corrugated section 102 are in the form of annular corrugations, and the third corrugated section 102 is in the form of spiral corrugations and is distributed at both ends of the optical fiber duct.

[0052] The fiber optic pipe is made of high-density polyethylene, which has excellent toughness. After being processed into a corrugated structure, it can further absorb external forces.

[0053] The second corrugated section 101 has a smaller depth than the third corrugated section 102. By reducing the depth, the second corrugated section 101 reduces the overall axial deformation of the optical fiber duct, preventing it from undergoing significant deformation due to factors such as ground subsidence when buried in the soil. The third corrugated section 102 increases the depth to reduce the angle between two adjacent corrugated walls, thereby enhancing the radial compressive strength of the optical fiber duct. The spiral arrangement of the first corrugated section 100 strengthens the torsional resistance at both ends of the optical fiber duct, facilitating splicing and installation with other ducts.

[0054] Example 2

[0055] like Figures 2 to 16 As shown, the optical fiber duct inspection device is used to inspect optical fiber ducts with corrugated section compression-strengthened structure, including a support unit, a clamping unit, and a moving unit.

[0056] The support unit includes a mounting component 203, and a retracting mechanism is provided inside the mounting component 203;

[0057] The clamping unit includes a clamping rod 400 and a stretching mechanism, while the retracting mechanism is used to retract the clamping rod 400.

[0058] The moving unit includes a sliding mechanism. The mounting component 203 is rotatably mounted on the sliding mechanism. When the sliding mechanism drives the mounting component 203 to move, the mounting component 203 rotates under the action of the fiber optic tube's own toughness. When the mounting component 203 rotates, it drives the clamping rod 400 to move along its own axial direction through the tensioning mechanism.

[0059] like Figures 4 to 6 As shown, the mounting component 203 further includes a mounting groove 204. The retracting mechanism is located inside the mounting groove 204. The retracting mechanism includes a support component 205, and a clamping rod 400 is movably inserted into the support component 205. A first pull rod 206 is fixedly installed on one side of the support component 205. The first pull rod 206 movably passes through the mounting component 203 and extends into the mounting groove 204. The retracting mechanism also includes a retracting assembly and a resetting assembly. The retracting assembly and the resetting assembly drive the clamping rod 400 to move via the first pull rod 206 and the support component 205. In this configuration, there are two support components 205 symmetrically distributed on both sides of the mounting component 203. The first pull rod 206 drives the support components 205 to move so that the corresponding clamping rods 400 form a clamping effect.

[0060] like Figures 5 to 6 As shown, the retractable assembly further includes a connector 207 fixedly connected to the first pull rod 206, a stop post 209 fixedly installed on one side of the connector 207, and a slide plate 212 fixedly installed on the side wall of the mounting groove 204. A mounting block 210 is slidably installed on the slide plate 212, and a guide rod 211 is fixedly installed at one end of the mounting block 210. When the guide rod 211 moves, it drives the first pull rod 206 to move by moving the stop post 209.

[0061] The reset assembly includes a first spring 208, which is movably sleeved on the first pull rod 206, and its two ends are respectively connected to the connector 207 and the inner wall of the mounting groove 204.

[0062] In this configuration, the middle part of the guide rod 211 is inclined so that the stop post 209 moves under the action of the guide rod 211. When the guide rod 211 disengages from the stop post 209, the tension of the first spring 208 pulls the connector 207 to reset the first pull rod 206.

[0063] like Figure 3 , Figure 8 As shown, the sliding mechanism further includes a slide rail 201 and a slider 202, and a base 200 is installed at the bottom of the slide rail 201, and the mounting part 203 is rotatably connected to the slider 202.

[0064] The support unit also includes a positioning mechanism, which includes a fixed frame 404 fixedly installed at the bottom of the mounting component 203, and a rod 306 movably inserted into the fixed frame 404. A positioning post 307 is fixedly installed at the bottom of the rod 306. The positioning mechanism also includes a mounting plate 308 fixedly installed on the slider 202. A positioning hole 309 is provided on the mounting plate 308. The positioning hole 309 is adapted to the positioning post 307. A telescopic post 310 is installed at the bottom of the mounting plate 308. A movable ring 311 is installed at the bottom of the telescopic post 310. A top post 312 is installed on the movable ring 311 and is aligned with the positioning hole 309.

[0065] In this setup, the slide rail 201 and the slider 202 are electrically driven and controlled by a PLC control board. In the initial state, the positioning pin 307 is inserted into the positioning hole 309, preventing the mounting part 203 from rotating with the slider 202. When the positioning pin 307 is disengaged from the positioning hole 309, the mounting part 203 and the slider 202 can rotate.

[0066] like Figures 6 to 8 As shown, a transmission mechanism is further provided between the positioning mechanism and the retracting mechanism. The transmission mechanism includes a rotating plate 300 rotatably connected to one end of the mounting member 203. A torsion spring 301 is installed between the rotating plate 300 and the mounting member 203. A groove 302 is provided on the rotating plate 300. A push block 304 is fixedly installed at one end of the mounting block 210. First protrusions 303 are installed on both sides of the push block 304, and second protrusions 305 are installed on both sides of the bottom of the insertion rod 306. The first protrusions 303 and the second protrusions 305 are movably connected within the rotating plate 300. In this configuration, when the rotating plate 300 rotates, it drives the groove 302 to rotate. The groove 302 drives the first protrusions 303 to move, thereby moving the push block 304. The groove 302 drives the second protrusions 305 to move, thereby moving the insertion rod 306. The lengths of the push block 304 and the insertion rod 306 are set so that they do not interfere with each other during movement.

[0067] like Figures 7 to 8As shown, the tensioning mechanism further includes a second pull rod 401 fixedly connected to the clamping rod 400. A first telescopic rod 402 is installed on the second pull rod 401. A first stop rod 403 is installed at the bottom of the first telescopic rod 402. A limit groove 405 is opened on the fixing frame 404. The first stop rod 403 moves through the limit groove 405. The tensioning mechanism also includes a guide member 406 fixedly installed on the outside of the mounting plate 308. When the first stop rod 403 moves along the mounting plate 308, it drives the clamping rod 400 to move along its own axial direction through the guide member 406. In this configuration, the end of the guide member 406 is inclined and the outer ring is circular. When the first stop rod 403 contacts the guide member 406, a small rotation angle is sufficient to move the first stop rod 403 so that the clamping rod 400 moves along the axial direction. At this time, the first stop rod 403 contacts the outer ring of the guide member 406. When the first stop rod 403 moves along the outer ring of the guide member 406, the first stop rod 403 will not continue to drive the clamping rod 400 to move along the axial direction.

[0068] like Figure 2 , Figure 10 , Figure 12 , Figure 13 As shown, it further includes a triggering unit, which includes a sliding seat 500 slidably mounted on the base 200. The sliding seat 500 is provided with a transverse mechanism, which includes a guide plate 501 fixedly mounted on the sliding seat 500 and a second stop 502 fixedly mounted on the bottom of the guide member 406. When the second stop 502 moves with the slider 202, it drives the sliding seat 500 to move through the guide plate 501.

[0069] The triggering unit also includes a triggering mechanism, which includes a rotating member 504 rotatably mounted on the sliding seat 500 and a fixing member 503 fixedly mounted on the sliding seat 500. A top block 505 is mounted on one end of the rotating member 504. An elastic component is provided between the rotating member 504 and the fixing member 503. The elastic component applies elastic force to the rotating member 504 to make the top block 505 push open the optical fiber channel. The elastic component includes a connecting post 506 fixedly mounted on one side of the rotating member 504. A second spring 507 is movably sleeved on the connecting post 506.

[0070] In this configuration, the fixing member 503 has a groove for the connecting column 506 to pass through. The dimension of the groove in the height direction is greater than the diameter of the connecting column 506, so that when the connecting column 506 rotates with the rotating member 504, the fixing member 503 will not block the connecting column 506.

[0071] like Figures 13 to 16As shown, furthermore, adjusting mechanisms are provided on both sides of the fixing member 503 and the rotating member 504. The adjusting mechanisms include a first protrusion 508 fixedly installed on both sides of the fixing member 503 and a second protrusion 509 fixedly installed on both sides of the rotating member 504. The adjusting mechanisms also include a rotating disk 510, on which a guide assembly is provided. The guide assembly includes a first guide surface 511, a second guide surface 512, a third guide surface 513, and a fourth guide surface 514. When the rotating disk 510 rotates, the distance between the first protrusion 508 and the second protrusion 509 is controlled through the guide assembly. In this configuration, by controlling the contact state between the first guide surface 511, the second guide surface 512 and the first protrusion 508, and the third guide surface 513, the fourth guide surface 514 and the second protrusion 509, the distance between the first protrusion 508 and the second protrusion 509 is changed, thereby achieving the maximum rotation angle change of the rotating member 504.

[0072] like Figures 9 to 12 As shown, the adjustment mechanism further includes a shaft shifting mechanism, which includes a rotating column 602 fixedly installed on one side of the rotating disk 510. The rotating column 602 has a first guide groove 603 and a second guide groove 604. A first movable rod 606 is provided at the bottom of the rotating column 602, and a guide block 605 is installed on the first movable rod 606. A connecting plate 607 is fixedly installed on one side of the first movable rod 606. A second movable rod 608 is fixedly installed at one end of the connecting plate 607. The second movable rod 608 is movably connected to the sliding seat 500. A lifting component is provided at one end of the second movable rod 608. The lifting component is used to control the lifting of the movable ring 311. A fixing block 600 is movably sleeved on the first movable rod 606. The fixing block 600 is fixedly connected to the sliding seat 500. A positioning groove 601 is provided on the fixing block 600. A handle 614 is fixedly installed at the end of the rotating column 602, and the handle 614 is movably connected to the positioning groove 601. In this configuration, when the first protrusion 508 contacts the first guide surface 511, the guide block 605 moves only within the first guide groove 603. When the first protrusion 508 contacts the second guide surface 512, the guide block 605 moves only within the second guide groove 604. The plane of the second guide groove 604 is parallel to the end face of the rotating column 602, so that when the rotating column 602 rotates, the second guide groove 604 will not drive the guide block 605 to move.

[0073] The contact area between the guide block 605 and the second guide groove 604 is relatively large, so that when the rotating disk 510 drives the rotating column 602 to move, part of the guide block 605 is still in the second guide groove 604.

[0074] The lifting assembly includes a second telescopic rod 612 installed at the top of both ends of the base 200, and a side connecting rod 610 is fixedly installed on the second telescopic rod 612. A push rod 609 is provided on one side of the side connecting rod 610, and the side connecting rod 610 and the base 200 are rotatably connected to the push rod 609 through a support rod 611. A lifting rod 613 is also installed on one side of the side connecting rod 610, and the lifting rod 613 is located at the bottom of the movable ring 311.

[0075] The implementation principle of the fiber optic duct inspection device in this embodiment is as follows: During inspection, the fiber optic duct needs to be installed on the inspection device, and the pipe openings at both ends of the fiber optic duct are aligned with the mounting part 203. At this time, the handle 614 is pressed down, and the handle 614 drives the rotating column 602 to rotate. The rotating column 602 drives the guide block 605 to move through the first guide groove 603, so that the guide block 605 drives the first movable rod 606 to move. The first movable rod 606 drives the second movable rod 608 to move through the connecting plate 607. The second movable rod 608 abuts against the push rod 609 to make it move. During the movement, the side connecting rod 610 is driven to rise through the support rod 611. The side connecting rod 610 drives the movable ring 311 to rise through the lifting rod 613. The movable ring 311 drives the positioning column 307 to rise through the top column 312, and makes the positioning column 307 disengage from the positioning hole 309.

[0076] As the positioning post 307 rises, it also drives the insertion rod 306 to rise. The insertion rod 306 drives the rotating plate 300 to rotate via the second protrusion 305, and drives the push block 304 to move via the first protrusion 303. The push block 304 drives the mounting block 210 to move. The mounting block 210 drives the guide rod 211 to move. The guide rod 211 drives the stop post 209 to move, thereby causing the first pull rod 206 to move. The first pull rod 206 drives the support member 205 to move, thereby causing the clamping rod 400 to clamp the optical fiber tube.

[0077] The slider 202 is controlled to slide on the slide rail 201. During the sliding process of the slider 202, due to the toughness of the optical fiber tube itself, the mounting part 203 rotates on the slider 202. During the rotation, the first telescopic rod 402 and the first stop rod 403 rotate together and move through the inclined side guidance of the guide 406. When moving, the clamping rod 400 is moved through the second pull rod 401 so that the clamping rod 400 can install the optical fiber tube into the mounting part 203.

[0078] When the handle 614 is pressed down, it drives the rotating disk 510 to rotate. When the rotating disk 510 rotates, the second protrusion 509 changes from contacting the third guide surface 513 to contacting the fourth guide surface 514. At this time, the first protrusion 508 still maintains contact with the first guide surface 511. The second spring 507 drives the rotating component 504 to rotate, so that the top block 505 pushes open the optical fiber tube. When the slider 202 moves, the two ends of the optical fiber tube are squeezed so that the middle part bends in the direction of being pushed open, thereby realizing the test of the bending resistance performance of the optical fiber tube.

[0079] During the movement of slider 202, it drives the mounting plate 308 and guide 406 to move. The second stop 502 at the bottom of guide 406 drives guide plate 501 to move to one side so that sliding seat 500 can move. At this time, the component connected to sliding seat 500 moves to prevent it from blocking the movement of slider 202.

[0080] When the top block 505 cannot effectively open the fiber optic pipe due to its own size or other reasons, the handle 614 can be rotated to make the rotating disk 510 continue to rotate. At this time, the first protrusion 508 is aligned with the second guide surface 512, and the second protrusion 509 is aligned with the fourth guide surface 514, so that the rotating disk 510 can move to one side. The second spring 507 drives the rotating part 504 to rotate at a larger angle, so that it drives the top block 505 to move a longer distance, thereby effectively opening the fiber optic pipe.
