Description

Technical Field

[0001] This utility model relates to the field of optical cable testing technology, and in particular to an optical cable coupling testing device. Background Technology

[0002] As the length of oil and gas pipelines continues to increase year by year, most oil and gas pipelines are equipped with accompanying optical cables. In order to prevent the accompanying optical cables from being damaged by third-party construction, the management units along the pipeline need to locate the optical cable position regularly or when encountering third-party construction.

[0003] Underground fiber optic cables accompanying oil and gas pipelines, being a type of communication fiber optic cable with a metal core, face challenges due to their small cross-section and lack of dedicated test stakes. Current methods for detection and positioning all require excavating test pits beforehand, connecting the testing equipment to the exposed fiber optic cable, and using a transmitter on a dedicated detection instrument to apply a current signal to the metal core of the cable at the excavation point. Alternatively, the detection instrument can be used to locate and detect the fiber optic cable under test, and then a receiver can be used for further location and depth detection of upstream and downstream cables via electromagnetic induction. This detection method necessitates excavating test pits before each underground fiber optic cable inspection operation; after testing, the pits must be backfilled, wasting time, manpower, and resources, impacting work efficiency. Furthermore, the continuous excavation of test pits increases the possibility of damage to the fiber optic cables accompanying the oil and gas pipelines. Utility Model Content

[0004] The purpose of this invention is to provide an optical cable coupling testing device that can reduce the time and labor costs of pit excavation and maintain the efficiency and safety of optical cables in positioning and testing.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Optical cable coupling testing device, including:

[0007] The optical cable coupling clamp includes two semi-circular clamps, one of which is wound with a lead wire, and both ends of the lead wire are provided with wire lugs; the two semi-circular clamps can selectively clamp optical cables located in underground pits.

[0008] Electrical tape is wrapped around the outside of the two semi-circular clamps to secure the optical cable coupling clamp to the optical cable.

[0009] Viscoelastic tape, the viscoelastic tape being wrapped around the outside of the electrical tape, capable of wrapping the two semi-circular clamps and the preset portions of the optical cable located on both sides of the semi-circular clamps;

[0010] A ground-based optical fiber cable post is fixedly erected on the ground. The ground-based optical fiber cable post has an inlet channel that connects to the ground. Both ends of the lead wire pass through the inlet channel. The wire lug is fixed to the ground-based optical fiber cable post for connecting the detector.

[0011] As an optional technical solution for optical cable coupling testing devices, the ring formed by stacking multiple layers of silicon steel sheets along the axial direction is cut into two semi-circular clamps.

[0012] As an optional technical solution for the optical cable coupling test device, the cut surfaces of the two semi-circular clamps are sprayed with paired codes.

[0013] As an optional technical solution for the optical cable coupling test device, the lead wire includes a winding section and two lead wire sections. The two ends of the winding section are respectively connected to the two lead wire sections. The winding section is wound around one of the semi-circular clamps. The wire diameter of the winding section is 0.47 mm, and the wire diameter of the lead wire section is greater than or equal to 2 mm.

[0014] As an optional technical solution for the optical cable coupling test device, protective sleeves are respectively fitted on the outer sides of the two lead segments, and the end of the lead segment away from the winding segment is exposed by the protective sleeve and fixed to the wire lug.

[0015] As an optional technical solution for the optical cable coupling test device, the two lead segments are jointly sleeved in a protective sleeve. The protective sleeve is used to lead the lead segments out of the ground and into the ground optical cable pile. The end of the lead segment away from the winding segment is exposed in the protective sleeve and fixed to the lug. A protective connector is sleeved at the fixed position of the lead segment and the lug.

[0016] As an optional technical solution for the optical cable coupling test device, the ground optical cable pile has two drill holes, which can connect the inlet channel to the outside of the ground optical cable pile. The optical cable coupling test device also includes two fixing members, which are respectively set to correspond one-to-one with the two drill holes and the two wire lugs. The fixing members can pass through the wire lugs and the drill holes in sequence, and the detector can be connected to the part of the fixing member that extends out of the ground optical cable pile.

[0017] As an optional technical solution for the optical cable coupling test device, the length of the part of the fixing member extending out of the ground optical cable pile ranges from 1 cm to 2 cm.

[0018] As an optional technical solution for the optical cable coupling test device, the fixing component is set as a bolt. The optical cable coupling test device also includes a connecting washer and a nut. The connecting washer is coaxially attached to both sides of the drill hole. The nut is threadedly connected to the part of the bolt that extends out of the ground optical cable pile, so that the head of the bolt clamps the wire lug with the connecting washer located inside the ground optical cable pile, and the nut abuts against the connecting washer located outside the ground optical cable pile.

[0019] As an optional technical solution for optical cable coupling testing devices, warning signs are provided on the outside of the ground optical cable piles.

[0020] The beneficial effects of this utility model are:

[0021] The optical cable coupling testing device provided by this utility model includes an optical cable coupling clamp, electrical tape, viscoelastic tape, and a ground optical cable stake. The optical cable coupling clamp includes two semi-circular clamps, which are made using the principle of electromagnetic induction coupling. A lead wire is wound around one of the semi-circular clamps. The two semi-circular clamps can selectively clamp the optical cable located in the underground pit. The electrical tape is wrapped around the outside of the two semi-circular clamps to fix the optical cable coupling clamp to the optical cable. The viscoelastic tape wrapped around the outside of the electrical tape can cover the two semi-circular clamps and the preset part of the optical cable located on both sides of the semi-circular clamps, forming a sealed and fixed structure to maintain the safety of the optical cable during position testing. The ground-based optical fiber cable bollard is fixed to the ground and has an entry channel that connects to the ground, ensuring that the bottom of the ground-based optical fiber cable bollard is open and easy to guide the cable. The two ends of the lead cable are led out of the ground and pass through the entry channel together. Both ends of the lead cable are equipped with cable lugs, which are fixed to the ground-based optical fiber cable bollard and can be used to connect to the detector. This saves the effort and cost of digging optical fiber cable test pits before each test, and allows the detector to directly connect to the cable lugs located on the ground. This can improve the efficiency of optical fiber cable positioning, reduce the time, labor costs and safety risks of test pit excavation, and improve work efficiency. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figures 1 to 4 As shown, this utility model discloses an optical cable coupling test device, including an optical cable coupling clamp 200, electrical tape 300, viscoelastic tape 400, and a ground optical cable stake 500. The optical cable coupling clamp 200, simulating a Radiometer clamp, specifically includes two semi-circular clamps 201, manufactured using the principle of electromagnetic induction coupling. Multiple layers of silicon steel sheets are stacked together along the axial direction to form a ring with a width of 10 mm; this ring is then cut into two semi-circular clamps 201, with the cut surfaces ground smooth and free of dirt. Matching codes are sprayed onto the cut surfaces of the two semi-circular clamps 201 for easy and rapid pairing to form the optical cable coupling clamp 200. A lead wire 210 is wound around one of the semi-circular clamps 201, allowing the two semi-circular clamps 201 to selectively clamp the optical cable 100 located in an underground pit. In some cases, an optical cable silicon tube 110 is fitted over the outside of the optical cable 100 to protect it, improving its corrosion resistance and sealing performance.

[0036] Specifically, the lead wire 210 includes a winding section and two lead wire sections. The two ends of the winding section are connected to the two lead wire sections respectively. The winding section is wound around one of the semi-circular clamps 201. The wire diameter of the winding section is 0.47 mm, and the wire diameter of the lead wire section is greater than or equal to 2 mm. The lead wire sections are two 5-meter-long soft copper wires.

[0037] In this embodiment, electrical tape 300 with a width of 2 cm is wrapped around the outside of the two semi-circular clamps 201 to fix the optical cable coupling clamp 200 to the optical cable 100; viscoelastic tape 400 with a width of 10 cm is wrapped around the outside of the electrical tape 300 to cover the two semi-circular clamps 201 and the preset portions of the optical cable 100 located on both sides of the semi-circular clamps 201, thus forming a sealed and fixed structure and maintaining the safety of the optical cable 100 during position testing.

[0038] Specifically, the ground-based optical fiber cable stake 500 is fixedly erected on the ground. The stake 500 has an entry channel that connects to the ground, ensuring the bottom of the stake 500 is open for easy cable routing. Both ends of the lead wire 210 are led out of the ground and pass through the entry channel. Each end of the lead wire 210 is equipped with a lug 220. The lug 220, fixed to the ground-based optical fiber cable stake 500, can be used to connect to detectors such as those from Radiodetection. This allows for long-term detection and positioning of the underground optical fiber cable 100 at the location of the stake 500, eliminating the need for excavating a test pit for the optical fiber cable 100 before each test. It facilitates direct connection of the detector to the lug 220 on the ground, improving the positioning efficiency of the optical fiber cable 100, reducing the time, labor costs, and safety risks associated with excavation, and increasing work efficiency. For example, the lug 220 can be made of copper.

[0039] Through actual testing and application, a single optical cable coupling test device can achieve unidirectional testing within a range of 1 to 2 kilometers, and bidirectional testing within a range of 2 to 4 kilometers, with a positioning accuracy higher than 0.2 meters, which is consistent with the detection distance and accuracy of detectors such as Radiant that are directly connected to optical cable 100.

[0040] Optionally, protective sleeves 211 are respectively fitted on the outer sides of the two lead segments, with the end of the lead segment away from the winding segment exposed by the protective sleeves 211 and fixed to the wire lugs 220, which can effectively protect the safety of the lead segments underground and on the ground.

[0041] In this embodiment, two lead segments are jointly sleeved within a protective sleeve 211. The protective sleeve 211 is used to lead the lead segments out of the ground and into the ground optical fiber anchor 500. The ends of the two lead segments furthest from the winding segment protrude from the protective sleeve 211 and are respectively fixed to the lugs 220. Protective connectors are sleeved at the fixing positions of the lead segments and the lugs 220. Both the protective sleeve 211 and the protective connectors can be transparent plastic tubes to facilitate observation of the position and connection of the lead segments.

[0042] Furthermore, the ground fiber optic cable post 500 has two holes pre-drilled at a suitable height using a hand drill. These holes connect the cable entry channel to the outside of the ground fiber optic cable post 500. The fiber optic cable coupling test device also includes two fixing members 510, each corresponding to one of the two drilling holes and one of the two lugs 220. The fixing members 510 can pass through the lugs 220 and the drilling holes in sequence. The detector can be connected to the portion of the fixing member 510 that extends beyond the ground fiber optic cable post 500. This allows for convenient connection between the lugs 220 and the fiber optic cable 100 from the outside of the ground fiber optic cable post 500. For example, the length of the fixing member 510 extending beyond the ground fiber optic cable post 500 ranges from 1 cm to 2 cm, ensuring a stable connection with the detector without excessive extension that could damage surrounding surfaces, effectively protecting the ground fiber optic cable post 500.

[0043] In this embodiment, the fixing member 510 is a bolt, and the optical cable coupling test device also includes a connecting washer and a nut. The connecting washer is coaxially attached to both sides of the drilled hole. The nut and the part of the bolt extending out of the ground optical cable post 500 are threadedly connected so that the head of the bolt abuts against the wire lug 220 and together with the connecting washer located inside the ground optical cable post 500 to clamp the wire lug 220. The nut abuts against the connecting washer located outside the ground optical cable post 500. By rotating the nut, the fixing member 510 can be controlled to install the wire lug 220 to the ground optical cable post 500, thereby improving the stability of the structure and facilitating disassembly and maintenance.

[0044] Understandably, the red warning sign painted on the outside of the ground fiber optic cable stake 500 can better remind passersby that fiber optic cable 100 is buried nearby; it is also more noticeable for staff who want to check the location of fiber optic cable 100.

[0045] This solution also discloses an installation and usage method for an optical cable coupling test device. First, a test pit is excavated to locate the optical cable 100, ensuring sufficient working space for personnel below the pit. The optical cable 100 or the optical cable silicon tube 110 is suspended in the air to provide sufficient working space for the subsequent installation of the optical cable coupling clamp 200. The surface of the optical cable 100 or the optical cable silicon tube 110 is cleaned to ensure it does not affect the performance of the optical cable coupling clamp 200 or the adhesion of the electrical tape 300 and viscoelastic tape 400. Next, it is checked whether the lead wire segment of the optical cable coupling clamp 200 has the lug 220 properly installed to facilitate secure fixing and connection at the joint later. Simultaneously, a protective sleeve 211 is placed over the lead wire segment to protect the lead wire 210 from damage during burial. Install the optical cable coupling clip 200 onto the cleaned optical cable 100 or optical cable silicon tube 110, and secure the optical cable coupling clip 200 with electrical tape 300. Then, use viscoelastic tape 400 to further protect and secure the optical cable coupling clip 200, ensuring its long-term effectiveness during underground use. Finally, lead the lead wire to the ground optical cable post 500, pass it through the inlet channel into the ground optical cable post 500, and use stainless steel bolts 510 as fasteners to secure the lug 220 and the lead wire to the ground optical cable post 500, completing the installation of the optical cable coupling test device. During testing, simply use the two clamps of the detector to clamp the portions of the two stainless steel bolts extending out of the ground optical cable post 500 to test and locate the upstream and downstream optical cables 100 at this location.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
