Description

Technical Field

[0001] The present invention relates to the technical field of optical cable operation and maintenance. More specifically, the present invention relates to a communication optical cable fault monitoring device. Background Art

[0002] With the rapid development of information technology, optical fiber communication has become the main way of information transmission in modern society. As the core carrier of optical fiber communication, the stability and reliability of the operating state of optical cables are directly related to the performance of the entire communication network. Among them, common communication optical cable faults are mostly found in the following situations: Impact of lightning: The armored components of optical cables are all metal conductors. If a short circuit occurs in the power line or lightning strikes a metal part, a strong current will be generated to damage the optical cable line equipment. In severe cases, even casualties may occur.

[0003] Poor insulation of the optical cable line: If the insulation work of the communication optical cable line is not done well, after the splice closure gets water or is in a damp state, the operating strength of the optical cable will be greatly reduced due to stress corrosion and static fatigue. In severe cases, the optical cable may break.

[0004] Influence of external forces: Line faults are often caused by the influence of external forces. Since many communication optical cable lines are laid in the wild and the general burial standard is to be buried deep below the ground layer, it is impossible to effectively avoid the damage of many external factors to the optical cable line.

[0005] Faults at the line joints: Faults are most likely to occur at the line joints because the optical fibers at the joints no longer have protection for the original optical cable structure or the protection has been significantly weakened. Therefore, the daily operation and protection work can only rely on the splice closure, which greatly increases the probability of faults.

[0006] Regardless of the above fault reasons, abnormal points will appear on the outer surface of the optical cable. To detect the optical cable fault points, optical cable fault monitoring equipment is required, especially the operating trolley that can move forward along the optical cable. However, due to the long length of the optical cable during laying, it shows a sagging and bending shape or there are relatively thick connection nodes in the middle of the line, which brings difficulties for the trolley to continue moving forward. And if an adaptive structure or even other accessories are used, it will increase the self-weight of the trolley, which will burden the stress strength of the optical cable and may cause damage to the optical cable due to the detection work. Summary of the Invention

[0010] In a preferred embodiment, the main carrier plate I, the main carrier plate II and the sinking basket are all fixed to the main carrier frame by bolts; At the top end of the main carrier frame, a wireless signal transceiver antenna is provided, on the outer wall of the upper cross plate I, a CCD camera is fixedly installed by bolts, wherein the storage battery is set as the energy supply for the wireless signal transceiver antenna, the CCD camera and the driving servo motor; positioning chips such as GPS and a wheel speed meter can be added to accurately locate the damaged part of the cable detection.

[0011] In a preferred embodiment, the limiting telescopic rod includes an inner rod, an outer cylinder, and a telescopic spring. The end of the outer cylinder is fixedly connected to the inner wall of the transverse sliding groove I. The top of the inner rod is connected to the steering shaft. The telescopic spring is received in the inner cavity of the outer cylinder, and the end of the inner rod is received in the inner cavity of the outer cylinder and is slidably connected along the inner cavity of the outer cylinder; The traffic-limiting bump is detachably and fixedly connected to the main carrier plate I by bolts; The wheel disc body includes a main body disc. An installation ring groove is formed at the connection between the outer edge of the main body disc and the flexible inlaid ring gasket, and an installation rotation groove is horizontally formed at the connection between the center of the main body disc and the steering shaft.

[0012] In a preferred embodiment, the traffic-blocking component includes a limiting groove, a positioning bump, and a limiting spring. The positioning bump and the limiting spring are received in the limiting groove, and one end of the positioning bump protrudes out of the limiting groove; The limiting groove is formed in the main body disc, and a plurality of limiting grooves are arranged in a circular array along the installation rotation groove; The positioning bump is set to a semi-spherical shape.

[0013] In a preferred embodiment, the flexible inlaid ring gasket includes a gasket body. A wire placement groove with a circular design is formed at the outer edge of the gasket body. The cross-sectional shape of the wire placement groove is set to a "V" shape, and a stress deformation groove is formed at the center of the wire placement groove; Air-dissipating through holes are formed between the inner wall of the stress deformation groove and the outer wall of the gasket body, and the outer wall of the gasket body and the stress deformation groove are communicated by the air-dissipating through holes; The number of the air-dissipating through holes is set to be multiple, and the multiple air-dissipating through holes are arranged in a circular array at equal intervals along the center line of the gasket body.

[0014] In a preferred embodiment, the flexible inlaid ring gasket is integrally injection-molded from a rubber material; A plurality of anti-slip ridges are uniformly fixed on the outer wall of the wire placement groove, and the plurality of anti-slip ridges are arranged in a circular array at equal intervals along the center line of the gasket body.

[0016] The beneficial effects of the present invention are: 1. In the present invention, the positioning bump and the traffic-limiting bump are used in cooperation with the upper wire pressing wheel. When the driving servo motor works to drive the lower wire supporting wheel to move forward, the upper wire pressing wheel is driven to move forward synchronously. The slight blocking force generated by the contact between the traffic-blocking component and the traffic-limiting bump creates a rotational speed difference between the upper wire pressing wheel and the lower wire supporting wheel, which is more conducive to the climbing / falling of the cable at the sliding or rising position. Moreover, when the upper wire pressing wheel and the lower wire supporting wheel reach a foreign object point, they are restricted by the body position. The steering shaft squeezes the limit telescopic rod to contract, and the upper wire pressing wheel together with the steering shaft retracts along the transverse sliding groove Ⅰ, enabling the device to smoothly pass through this point, which is conducive to ensuring the efficient and safe operation of the optical cable line.

[0017] 2. In the present invention, through the assembled structure of the wheel disc body and the flexible embedded ring gasket, the fully enclosed outer shell is cancelled, reducing the self-weight of the overall device and facilitating the threading of the cable into the device. The optical cable is clamped between the upper wire pressing wheel and the lower wire supporting wheel. By driving the driving servo motor to work to drive the lower wire supporting wheel to rotate, the lower wire supporting wheel drives the upper wire pressing wheel to rotate synchronously when moving forward along the optical cable. The wire placement groove of the flexible embedded ring gasket is arranged in a groove shape, and the cable is in direct contact with the surface of the wire placement groove. The design of the through-type air dispersion through holes can avoid the adsorption effect caused by the suction cup type air pressure difference between the flexible embedded ring gasket and the outer wall of the optical cable, which affects the forward movement of the device. Therefore, it effectively avoids the secondary damage to the cable detection caused by the excessive self-weight of the traditional transmission trolley. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] Embodiment 1: As Figure 1-2As shown in the figure, the present invention provides a communication optical cable fault monitoring device, which includes a main carrier frame 01. On both sides of the upper middle part of the main carrier frame 01, an upper cross plate I 02 and an upper cross plate II 03 are respectively and fixedly installed. On both sides of the lower middle part of the main carrier frame 01, a lower cross plate I 04 and a lower cross plate II 05 are respectively and fixedly installed. Upper wire pressing wheels 06 are provided at the corresponding positions at both ends of the upper cross plate I 02 and the upper cross plate II 03. Lower supporting wheels 07 are provided at the corresponding positions at both ends of the lower cross plate I 04 and the lower cross plate II 05. A driving servo motor 08 is provided at the position where the outer wall of the lower cross plate I 04 and the lower cross plate II 05 is aligned with the central axis of one of the lower supporting wheels 07. A sinking basket 11 is fixedly provided at the bottom end of the main carrier frame 01, and a storage battery 12 is provided inside the sinking basket 11. A wireless signal transceiver antenna 10 is provided at the top end of the main carrier frame 01. A CCD camera 09 is fixedly installed on the outer wall of the upper cross plate I 02 through bolts. Connecting wires are arranged between the storage battery 12, the wireless signal transceiver antenna 10, the CCD camera 09 and the driving servo motor 08. The storage battery 12 is set as the energy supply for the wireless signal transceiver antenna 10, the CCD camera 09 and the driving servo motor 08. Precise positioning accessories such as a positioning chip and a wheel speed meter can be added to accurately position the damaged part of the cable detection. During this period, the real-time monitoring picture / information can be transmitted to the monitoring terminal (ground maintenance personnel) by the wireless signal transceiver antenna 10, so as to realize real-time viewing.

[0034] As Figure 3-4 As shown in FIGS. 5 and 6, the upper cross plate I 02 and the lower cross plate I 04 both include a main carrier plate I 021, and the upper cross plate II 03 and the lower cross plate II 05 both include a main carrier plate II 031. The upper cross plate I 02, the lower cross plate I 04 and the main carrier frame 01 together form a "work" shape. Protective plates I 022 are provided at both ends of the main carrier plate I 021. Protective plates II 032 are fixedly provided at both ends of the main carrier plate II 031. The protective plate II 032 corresponding to the upper cross plate II 03 is folded downward, and the protective plate II 032 corresponding to the lower cross plate II 05 is folded upward. The protective plate II 032 is set as a "T" - shaped plate, and the protective plate II 032 and the main carrier plate II 031 together form an "n" - shaped plate. The main carrier plate I 021, the main carrier plate II 031 and the sinking basket 11 are all fixed to the main carrier frame 01 through bolts.

[0035] Transform the shell of the traditional forward trolley into the connection structure of the upper cross plate I 02, the lower cross plate I 04, the upper cross plate II 03 and the lower cross plate II 05 with the main carrier frame 01, and cancel the fully enclosed shell. On the one hand, the self - weight of the overall device can be reduced. On the other hand, it is more convenient for the optical cable to pass through the gap between the upper cross plate I 02 and the lower cross plate I 04, so that the optical cable is clamped between the upper wire pressing wheel 06 and the lower supporting wheel 07. The settings of the protective plate I 022 and the protective plate II 032 can form longitudinal protection at the side wall to prevent the optical cable from falling off due to the deviation of the upper wire pressing wheel 06 and the lower supporting wheel 07, and the continuous monitoring work cannot be carried out.

[0036] As Figure 7-8As shown in the figure, the upper wire pressing wheel 06 and the lower wire supporting wheel 07 both include a wheel disc body 001. A flexible inner embedded ring gasket 002 is sleeved on the outer edge of the wheel disc body 001, and a steering shaft 003 is rotatably arranged at the center of the wheel disc body 001; the upper wire pressing wheel 06 and the lower wire supporting wheel 07 are respectively loaded in place by the steering shaft 003, and the wheel disc body 001 is rotatably connected along the steering shaft 003; the height of the bottom end of the upper wire pressing wheel 06 is set at the same horizontal height as the height of the top end of the lower wire supporting wheel 07; the side edge of the upper wire pressing wheel 06 and the steering shaft 003 corresponding to the lower wire supporting wheel 07 are set in the same longitudinal line position.

[0037] Referring to Figure 9 , the wheel disc body 001 corresponding to the upper wire pressing wheel 06 includes a main body disc 061. An installation ring groove 062 is opened at the connection between the outer edge of the main body disc 061 and the flexible inner embedded ring gasket 002, and an installation rotation groove is horizontally opened at the connection between the center of the main body disc 061 and the steering shaft 003; the wheel disc body 001 corresponding to the lower wire supporting wheel 07 is fixedly connected to the steering shaft 003, the output shaft of the driving servo motor 08 is fixedly connected to the steering shaft 003 corresponding to the lower wire supporting wheel 07, and the lower cross plate I 04 and the lower cross plate II 05 are rotatably connected to the steering shaft 003 corresponding to the lower wire supporting wheel 07.

[0038] The upper wire pressing wheel 06 and the lower wire supporting wheel 07 rotate synchronously, so that the optical cable wire body is clamped between the upper wire pressing wheel 06 and the lower wire supporting wheel 07. The driving servo motor 08 works to drive the lower wire supporting wheel 07 to rotate, so that the lower wire supporting wheel 07 drives the upper wire pressing wheel 06 to rotate synchronously when moving forward along the optical cable, ensuring that the device can move forward smoothly along the optical cable line.

[0039] Referring to Figure 12 , the flexible inner embedded ring gasket 002 is integrally injection-molded from a rubber material; the flexible inner embedded ring gasket 002 includes a gasket body 071. A wire placement groove 072 with a circular design is opened at the outer edge of the gasket body 071. The cross-sectional shape of the wire placement groove 072 is set as a "V" shape. The wire placement groove 072 with an inclined surface of the "V" shape can increase the contact area between the flexible inner embedded ring gasket 002 and the cable compared with the wire placement groove 072 with a flat surface or a convex surface. A stress deformation groove 074 is opened at the center of the wire placement groove 072; air dispersion through holes 075 are opened between the inner wall of the stress deformation groove 074 and the outer wall of the gasket body 071, and the outer wall of the gasket body 071 and the stress deformation groove 074 are communicated by the air dispersion through holes 075; the number of the air dispersion through holes 075 is set as multiple, and the multiple air dispersion through holes 075 are equidistantly arranged in a circular array along the center line of the gasket body 071; a plurality of anti-slip convex strips 073 are uniformly fixed on the outer wall of the wire placement groove 072, and the plurality of anti-slip convex strips 073 are equidistantly arranged in a circular array along the center line of the gasket body 071.

[0040] When assembling the upper wire pressing wheel 06 or the lower wire supporting wheel 07, the flexible embedded ring gasket 002 is loaded at the position of the mounting ring groove 062. The wire placing groove 072 of the flexible embedded ring gasket 002 is arranged in a groove shape, so that when the upper wire pressing wheel 06 and the lower wire supporting wheel 07 drive along the optical cable, the cable is in direct contact with the surface of the wire placing groove 072. The anti-slip convex strip 073 can enhance the friction force at the contact position between the surface of the optical cable and the flexible embedded ring gasket 002. When the flexible embedded ring gasket 002 is restricted by the position of the optical cable, slight deformation occurs at the stress deformation groove 074, so that the upper wire pressing wheel 06 and the lower wire supporting wheel 07 adaptively match the shape of the optical cable. Moreover, the through-type air-diffusing through hole 075 design can avoid the adsorption effect of the flexible embedded ring gasket 002 with a suction cup type air pressure difference on the outer wall of the optical cable, which affects the forward movement of the device. As the upper wire pressing wheel 06 and the lower wire supporting wheel 07 move forward along the optical cable, the CCD camera 09 takes pictures of the appearance of the cable, so as to determine the fault point by taking pictures of the abnormal points on the outer surface of the cable to determine the cable monitoring work.

[0041] Embodiment 2: Based on the optical cable fault monitoring device proposed in Embodiment 1, the present invention provides further technical solutions for the upper wire pressing wheel 06, the upper cross plate I 02, and the upper cross plate II 03.

[0042] Please refer to Figure 4-6 , a transverse movement chute I 023 is opened at the alignment connection position between the main carrier plate I 021 provided by the present invention and the upper wire pressing wheel 06, and a transverse movement chute II 033 is opened at the alignment connection position between the main carrier plate II 031 and the upper wire pressing wheel 06; a limiting telescopic rod 024 is fixedly arranged on the inner walls of the transverse movement chute I 023 and the transverse movement chute II 033, and limit bumpers 025 are arranged on both sides of the transverse movement chute I 023 and the transverse movement chute II 033; the limit bumpers 025 are detachably and fixedly connected to the main carrier plate I 021 through bolts.

[0043] Refer to Figure 11 , the limiting telescopic rod 024 includes an inner rod, an outer cylinder, and a telescopic spring. The end of the outer cylinder is fixedly connected to the inner wall of the transverse movement chute I 023. The top of the inner rod is fixedly connected to the steering shaft 003. The telescopic spring is received in the inner cavity of the outer cylinder, and the end of the inner rod is received in the inner cavity of the outer cylinder and is slidably connected along the inner cavity of the outer cylinder.

[0044] Refer to Figure 8 , a blocking component 004 is arranged in a circular array on the outer wall of the wheel disc body 001 corresponding to the upper wire pressing wheel 06. Refer to Figure 9-10 , the blocking component 004 includes a limiting groove 063, a positioning convex block 064, and a limiting spring 065. The positioning convex block 064 and the limiting spring 065 are received in the limiting groove 063, and one end of the positioning convex block 064 protrudes out of the limiting groove 063; the limiting groove 063 is opened in the main body disc 061, and a plurality of limiting grooves 063 are arranged in a circular array along the installation rotation groove; the positioning convex block 064 is set to be semi-spherical.

[0045] The working process is as follows: when the servo motor 08 is driven to drive the lower support wheel 07 forward, the main carrier 01, the sinking basket 11 and the battery 12 are deadweighted to ensure the position of the device after being assembled on the cable, effectively avoiding the displacement of the position and detachment from the cable and falling. The upper pressing wheel 06 is driven to move forward synchronously by the friction between the anti-skid ridges 073 corresponding to the wire groove 072 disposed on the outer ring of the flexible embedded ring pad 002 and the cable. During this period, because the limiting protrusion 025 protrudes from the inner wall of the main carrier plate Ⅰ021, and the positioning protrusion 064 protrudes from the outer wall of the wheel disc body 001 corresponding to the upper pressing wheel 06, the main disc 061 corresponding to the upper pressing wheel 06 rotates, and the positioning protrusion 064 on the outer wall rotates to the position of the limiting protrusion 025 and is blocked by the lateral position. The positioning protrusion 064 is restricted by the position of the limiting protrusion 025 and drives the length of the limiting spring 065 to shrink, so that the top of the positioning protrusion 064 is immersed in the limiting groove 0 At position 63, the limiting protrusions 025 corresponding to the upper transverse plate Ⅰ02 and the upper transverse plate Ⅱ03 lose their barrier to the blocking component 004 at this position, and as the main plate 061 continues to rotate, the positioning protrusions 064 are reset under the action of the rebound force of the limiting spring 065, and under the horizontal cable path, the friction force between the flexible embedded ring pad 002 and the cable offsets the barrier force between the blocking component 004 and the limiting protrusions 025, ensuring the upper wire pressing wheel 06 and the lower wire supporting wheel 07 to move forward synchronously.

[0046] When the long cable is in an arc shape, in the downward or upward position, the cable will be in a non-straightened state. Because the positioning protrusion 064 is restricted by the position of the limiting protrusion 025, the slight blocking force generated by the friction between the blocking component 004 and the limiting protrusion 025 produces a speed difference between the upper wire pressing wheel 06 (driven wheel) and the lower wire supporting wheel 07 (driving wheel). The clamping section of the cable by the upper wire pressing wheel 06 and the lower wire supporting wheel 07 on the front and rear sides is tightened, which is more conducive to the climbing / falling of the cable at the upward / sliding position, and ensures the clarity of the tensioned section of the cable captured by the CCD camera 09, avoiding the bending of the cable affecting the forward movement of the device and the shooting quality of the CCD camera 09.

[0047] And if there are nodes or connecting terminals (thicker than the cable) in the cable of the monitoring section, the upper pressing wheel 06 and the lower supporting wheel 07 will be restricted by their position when they reach the foreign object point. The steering shaft 003 corresponding to the upper pressing wheel 06 will be restricted to the backward position, and the steering shaft 003 will squeeze the limiting telescopic rod 024 to shrink, so that the upper pressing wheel 06 and the steering shaft 003 will shrink along the transverse slide groove Ⅰ023, so that the device can pass through the foreign object point smoothly without additional operation, and can adaptively pass through the cable with the foreign object point.

[0048] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0049] The above are only the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
