Description

Technical Field

[0001] The present invention relates to the technical field of optical cable fault detection, and in particular to an optical cable fault detection device based on the Internet. Background Art

[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective sleeves and plastic outer sheaths. Optical cables are a certain number of optical fibers arranged into a cable core in a certain manner, which is covered with a sheath and sometimes an outer sheath to realize a communication line for optical signal transmission. Optical cable lines are important infrastructure in the Internet. Because the optical fibers inside the optical cables are very thin and fragile, they are easily damaged when damaged by external forces, resulting in the ineffective transmission of optical signals. At this time, it is necessary to use an optical cable fault detection device to find the fault point on the optical cable through OTDR technology, power meter method and red light source method, and repair the fault point in time.

[0003] When using the existing Internet optical cable fault detection device, in order to increase the accuracy and convenience of optical cable fault point investigation and positioning, the OTDR output port, power meter output port and red light source output port are integrated into one Internet optical cable fault detection device, so that fault detection personnel can quickly switch between different optical cable fault detection methods as needed. However, when the current Internet optical cable fault detection device uses one of the detection methods to connect to the optical cable connector for fault detection, the other two output ports will also be exposed to the outside. The Internet optical cable fault detection device has poor safety protection for the three output ports, resulting in external dust, impurities or water vapor entering the two exposed output ports when the fault detection personnel work outdoors, affecting the accuracy of subsequent optical cable fault detection, and making the OTDR output port, power meter output port and red light source output port extremely susceptible to damage due to dust and impurity contamination, thereby reducing the overall service life of the Internet optical cable fault detection device.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing Internet optical cable fault detection device, and even if it can be solved, it needs to be solved through the cooperation of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose an Internet-based optical cable fault detection device. Summary of the Invention

The left side of the detector 11 is fixedly connected to three clamping seats 2113, and the interior of each clamping seat 2113 is slidably connected to two positioning blocks 2114, and the left side of each positioning block 2114 is an inclined surface with a certain inclination angle, and the inner wall of each positioning block 2114 is fixedly connected to a sliding rod 2116, and each sliding rod 2116 is slidably connected to the interior of the clamping seat 2113, and each clamping seat 2113 is fixedly connected to the left side of the detector 11.

By providing a separate protection unit 21, it is possible to provide separate protection space for the OTDR output port 14, the power meter output port 15 and the red light source output port 16 respectively.The OTDR output port 14, the power meter output port 15, and the red light source output port 16 can be easily opened and used, so that when a single output port is used to detect faults in an Internet optical cable, the other two output ports can be effectively protected and will not be directly exposed to the outdoors, making it difficult for external dust and impurities to contaminate the other two output ports. This increases the safety protection performance of the Internet optical cable fault detection device for the three detection output ports, ensures the accuracy of data collection for optical cable fault detection at the output ports, and prevents the OTDR output port 14, the power meter output port 15, and the red light source output port 16 from being damaged by dust and impurities, thereby increasing the overall service life of the Internet optical cable fault detection device.

The upper surface of each pushing rod 2110 is fixedly connected with a reinforcing rib 2121, and the other end of each reinforcing rib 2121 is fixedly connected to the outer surface of the connecting rod 2109. The multi-stage telescopic rod 2120 can prevent the first spring 2104 from being excessively twisted inside the protective shell 2101, thereby avoiding the first spring 2104 from contacting with the OTDR output port 14, the power meter output port 15 and the red light source output port 16 and causing wear.

An auxiliary telescopic rod 2123 is provided inside each third spring 2119, and the telescopic end of each auxiliary telescopic rod 2123 is fixedly connected to the inner wall of the push frame 2117, and the right end of each auxiliary telescopic rod 2123 is fixedly connected to the left side of the detector 11.

[0022] The specific implementation of this embodiment is as follows: manually pressing the pressing plate 2111 to the right in conjunction with the pushing rod 2110 and the connecting rod 2109 can drive the sliding block 2103 to slide to the right inside the protective shell 2101, thereby forcing the first spring 2104 to stretch and accumulate elastic force. As the sliding block 2103 moves to the right, the first guide rod 2105 can cooperate with the second guide rod 2106 and the third guide rod 2107 to push the cover plate 2102 upward through the connecting frame 2108 through the four-link structure, so that the OTDR output port 14, the power meter output port 15 and the red light source output port 16 inside the protective shell 2101 are exposed to the outside, so that the staff can connect the Internet optical cable connector that needs to be fault detected to the corresponding output port for fault detection, and when pressing When the plate 2111 moves to the right to open the cover 2102, it will also drive the clamping block 2112 to move to the right until the clamping block 2112 is inserted into the clamping seat 2113. When the clamping block 2112 enters the clamping seat 2113, the inclined surface of the positioning block 2114 can be used to push the positioning block 2114 to retract into the clamping seat 2113, forcing the second spring 2115 to retract, and the sliding rod 2116 slides inside the clamping seat 2113 and the guide groove 2118, and the inclination of the guide groove 2118 is used to force the pressing frame 2117 to move to the right. The third spring 2119 is retracted, and when the positioning block 2114 is parallel to the groove on the clamping block 2112, the elastic force of the second spring 2115 can push the positioning block 2114 to be clamped into the clamping seat. The positioning block 2114 is forced to retract into the inside of the card seat 2113 by utilizing the inclination of the guide groove 2118 in combination with the sliding rod 2116, thereby releasing the card with the card block 2112. When the sliding block 2103 is reset, the first guide rod 2105, the second guide rod 2106, the third guide rod 2107 and the connecting frame 2108 can cooperate with each other to drive the cover 2102 to close, thereby protecting the unused output ports. In addition, the OTDR output port 14, the power meter output port 15 and the red light source output port 16 can be provided with separate protection spaces. At the same time, the OTDR output port 14, the power meter output port 15 and the red light source output port 16 can be ensured to be convenient when they are opened and used, so that when a single output port is used to detect faults on the Internet optical cable, the other two output ports can be effectively protected and will not be directly exposed to the outdoors.This prevents external dust and impurities from contaminating the other two output ports, increasing the safety protection performance of the Internet optical cable fault detection device for the three output ports, ensuring the accuracy of data collection for output optical cable fault detection, and making the OTDR output port 14, power meter output port 15, and red light source output port 16 less likely to be damaged by dust and impurities, thereby extending the overall service life of the Internet optical cable fault detection device.

The reinforcement plates 2217 can increase the connection strength between the positioning plates 2208 and the protective cover 2201, making it difficult for the positioning plates 2208 to deform after being subjected to force, thereby improving the pressure bearing strength of the positioning plates 2208. The outer surfaces of the two clip-on frames 2210 are both slidably connected with a stabilizing sleeve 2218, and the right sides of the two stabilizing sleeves 2218 are fixedly connected to the left side of the detector 11. The stabilizing sleeve 2218 can limit the position of the clip-on frame 2210 without affecting the sliding of the clip-on frame 2210, thereby increasing the accuracy and stability of the clip-on frame 2210 during the forward and backward sliding process.

[0025] The specific implementation of this embodiment is as follows: when the detector 11 is not in use, the protective cover 2201 is first rotated counterclockwise to the left. At this time, the protective cover 2201 can drive the fixed column 2202 to rotate inside the sliding seat 2203, and force the torsion spring 2204 to twist and accumulate elastic force until the protective cover 2201 is rotated to the left until the clamping column 2205 is clamped into the U-shaped seat 2206, and the protective cover 2201 and the detector 11 remain relatively parallel. Then, the protective cover 2201 is pressed downward, and the protective cover 2201 can push the sliding seat 2203 and the U-shaped seat 2206 downward to slide downward inside the detector 11 through the fixed column 2202 and the clamping column 2205, and at the same time force the fourth spring 2207 to contract. Moreover, when the protective cover 2201 moves downward When the locking cam 2201 is in contact with the upper surface of the detector 11, the locking cam 2208 is pressed against the locking cam 2208, and the locking cam 2208 is pressed against the locking cam 2208. When the locking cam 2201 is in contact with the upper surface of the detector 11, the locking cam 2208 is pressed against the locking cam 2208, and the locking cam 2208 is pressed against the locking cam 2208. The sturdy protective structure makes the OTDR output port 14, the power meter output port 15 and the red light source output port 16 less susceptible to bumps. At the same time, the double-layer safety protection measures of the protective cover 2201 and the protective shell 2101 make the safety protection measures of the Internet optical cable fault detection device for the three output ports more superior. When it is necessary to use the detector 11 again to perform Internet optical cable fault detection through the OTDR output port 14, the power meter output port 15 and the red light source output port 16, it is only necessary to press the pressing plate 2216 to the right and cooperate with the anti-drop frame 2214 to limit the conical block 2215, so as to push the conical block 2215 to move to the right. At this time, the conical surface of the conical block 2215 cooperates with the inclined surface of the clamping frame 2210, so as to push the two clamping frames 2210 to each other. When the locking cam 2205 is in the closed position, the locking cam 2205 is in the closed position, and the locking cam 2205 is in the closed position, so that the locking cam 2205 is in the closed position, and the locking cam 2205 is in the closed position, so that the locking cam 2205 is in the closed position, and the locking cam 2205 is in the closed position, so that the locking cam 2205 is in the closed position, and the locking cam 2205 is in the closed position, so that the locking cam 2205 is in the closed position, and the locking cam 2205 is in the closed position, so that the locking cam 2205 is in the closed position,The protective cover 2201 can be fully opened by rotating clockwise to the right through the fixing column 2202, so that the tester can use the OTDR output port 14, power meter output port 15 and red light source output port 16 on the tester 11.

[0026] Example 3: Please refer to Figure 4 、 Figures 9-11 The present invention provides a technical solution: an Internet-based optical cable fault detection device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A sealing mechanism 3 is provided inside the overall protection unit 22. The sealing mechanism 3 is used in conjunction with the protective mechanism 2. The sealing mechanism 3 is used to increase the sealing performance of the overall protection unit 22 after it is closed.

[0027] As a further limitation of the sealing mechanism 3 of the present invention, the sealing mechanism 3 includes an annular airbag 301, which is arranged inside the detector 11, and the outer surface of the annular airbag 301 is in contact with the bottom surface of the protective cover 2201. The outer surfaces of the annular airbag 301 are fixedly connected with a one-way valve 302 and a pressure relief valve 303, respectively. The air inlet end of the one-way valve 302 and the exhaust end of the pressure relief valve 303 both pass through the left side of the detector 11. A hollow cylinder 304 is provided inside each fourth spring 2207, and the bottom end of each hollow cylinder 304 is fixedly connected to the inner bottom wall of the detector 11. The interior of each hollow cylinder 304 is slidably connected to a telescopic sleeve 305, and the interior of each telescopic sleeve 305 is slidably connected to a piston rod 306. The bottom surfaces of the two sliding seats 2203 and the two U-shaped The bottom surface of the seat 2206 is fixedly connected to the top of the piston rod 306, and the bottom end of each hollow cylinder 304 is fixedly connected to a connecting pipe 307. Each connecting pipe 307 passes through the detector 11 and extends to the interior of the annular airbag 301. By providing a sealing mechanism 3, it can cooperate with the overall protection unit 22 to further seal the gap between the protective cover 2201 and the detector 11 after the protective cover 2201 is closed, so that external impurities and finer dust such as water vapor are less likely to enter the OTDR output port 14, the power meter output port 15 and the red light source output port 16 to cause pollution, thereby further improving the safety protection effect of the Internet optical cable fault detection device on the OTDR output port 14, the power meter output port 15 and the red light source output port 16 when it is carried and used outdoors; Several rubber belts 308 are fixedly connected to the outer surface of the annular airbag 301, and the other ends of the several rubber belts 308 are fixedly connected to the inner wall of the detector 11. The rubber belts 308 can limit the position of the annular airbag 301 inside the detector 11 without affecting the expansion of the annular airbag 301, thereby preventing the annular airbag 301 from detaching from the detector 11.

[0028] The specific implementation of this embodiment is as follows: when the protective cover 2201 closes and protects the OTDR output port 14, the power meter output port 15 and the red light source output port 16, as the sliding seat 2203 and the U-shaped seat 2206 move downward, the piston rod 306 can be driven to move downward, and the telescopic sleeve 305 can be gradually contracted, so that the air inside the telescopic sleeve 305 and the hollow cylinder 304 is squeezed into the annular airbag 301 through the connecting pipe 307 without affecting the downward sliding of the sliding seat 2203 and the U-shaped seat 2206. The annular airbag 301 expands accordingly, thereby further sealing the gap between the protective cover 2201 and the detector 11, making it more difficult for external impurities and water vapor and other finer dust to enter the OTDR output port 14, the power meter output port 15 and the red light source output port 16 to cause pollution, thereby further improving the safety protection effect of the Internet optical cable fault detection device on the OTDR output port 14, the power meter output port 15 and the red light source output port 16 when the Internet optical cable fault detection device is carried and used outdoors, and by releasing pressure The valve 303 can discharge the excess gas inside the annular airbag 301 to the outside, preventing the annular airbag 301 from over-expanding and affecting the smooth closing of the protective cover 2201. When the protective cover 2201 is unfolded, as the sliding seat 2203 and the U-shaped seat 2206 move upward under the push of the fourth spring 2207, the sliding seat 2203 and the U-shaped seat 2206 can drive the piston rod 306 to move upward and allow the telescopic sleeve 305 to gradually unfold, which can be done without affecting the upward movement of the sliding seat 2203 and the U-shaped seat 2206. While moving, the gas inside the annular airbag 301 is re-absorbed into the hollow cylinder 304 and the telescopic sleeve 305 through the connecting tube 307, preparing for the next inflation of the annular airbag 301. In addition, the one-way valve 302 can be used to send external air into the annular airbag 301 to prevent the problem that there is too little gas inside the annular airbag 301, resulting in insufficient air pressure inside the hollow cylinder 304 and the telescopic sleeve 305, and causing the sliding seat 2203 and the U-shaped seat 2206 to be unable to slide upward to the appropriate position.
