Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical cable construction technology, specifically to an optical cable fixing and protection device. Background Technology
[0002] Currently, to endow long-distance pavement structures with intelligent sensing capabilities, intelligent sensing optical cables are being widely applied in the transportation sector, with an increasing number of new transportation projects requiring their installation. During the construction of intelligent airport runways and intelligent highway pavements, intelligent sensing optical cables need to be laid simultaneously during the pavement structure pouring process. Since pavement structure pouring typically employs segmented or skip-segment construction, end molds are frequently used for mold construction of the construction sections. However, since the optical cable is already pre-embedded beneath the construction section, the fixing of the end mold inevitably results in anchors being driven into the already laid optical cable, causing damage and severely impacting cable survival quality and construction progress. During the laying process, it is crucial to maintain consistent sensing functionality across the entire cable. If uneven stress occurs due to varying stress in certain areas, the stress will be superimposed on the cable, leading to significant interference and errors during long-term monitoring.
[0003] If conventional circular tube sleeves are used for protection, the protective tubes are prone to invisible, hidden deformation within the pavement structure due to the repeated rolling of construction vehicles during construction. This introduces additional stress into the sensing fiber optic cable, resulting in uneven stress on the cable and long-term monitoring errors. Furthermore, the deformed areas of the circular tubes are prone to cuts, causing fatal severance to the fiber optic cable, rendering it completely incapable of sensing. Utility Model Content

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] like Figures 1-3 As shown, this embodiment discloses an optical cable fixing and protection device, including a first component 1, a second component 2, and a third component 3, which are connected end-to-end to form a triangular interlocking structure. The first component 1 has a fixed end 11 and a movable end 12, and the second component 2 has a fixed end 21 and a movable end 22. The fixed end 11 of the first component and the fixed end 21 of the second component are hinged and fixed by an anchoring fork 4. The movable ends 12 of the first component and 22 of the second component are respectively movably connected to the third component 3. When the optical cable fixing and protection device is subjected to external force, the movable ends 12 of the first component and / or 22 of the second component can move in the extending direction of the third component 3. An elastic reset mechanism can be provided in the anchoring fork 4 so that when the external force on the optical cable fixing and protection device is removed, the movable ends of the first and second components can return to their initial positions.
[0019] The optical cable can be installed within the triangular space formed by the connection of the first component 1, the second component 2, and the third component 3. For example... Figure 1 As shown, when the optical cable 5 fixing and protection device is subjected to a lateral external force, such as when the first component 1 is subjected to an external force, the first component 1 rotates around the anchor fork 4 as the center, and the movable end 12 of the first component moves inward to get closer to the optical cable 5; when the optical cable 5 fixing and protection device is subjected to a vertical external force, such as when the anchor fork 4 is subjected to an external force, the first component 1 and the second component 2 rotate around the anchor fork 4 as the center, and the movable end 12 of the first component and the movable end 22 of the second component move inward to get closer to the optical cable 5. The external force is unloaded by moving the movable ends of the first component and / or the second component in the extension direction of the third component, avoiding stress or damage to the optical cable; and the optical cable fixing and protection device as a whole can maintain a stable triangular support structure before and after movement, which is not easy to flip or move, thus improving the stability of the device.
[0020] Specifically, the third component 3 is an arc structure. The arc structure of the third component 3 is adapted to the arc trajectory of the movable end of the first component 1 and the second component 2 during rotation, so that the rotation of the first component 1 and the second component 2 will not be separated from the third component 3 or obstructed by the third component 3.
[0021] Specifically, the first component 1 and the second component 2 are arc structures. The distance from the movable end 12 of the first component to the midpoint of the second component 2, the distance from the movable end 22 of the second component to the midpoint of the first component 1, and the distance from the anchor fork 4 to the midpoint of the third component 3 are all equal, ensuring that the height difference remains unchanged no matter how the optical cable fixing and protection device is placed during installation, and does not affect the installation of the upper pavement structure.
[0022] Specifically, the third component 3 has a first slide groove 31 and a second slide groove 32 at both ends, and the movable end 12 of the first component and the movable end 22 of the second component are respectively disposed in the first slide groove 31 and the second slide groove 32. The movable ends of the first component and the second component can move in the slide grooves, and the slide grooves facilitate the provision of displacement space for the first component and the second component.
[0023] Specifically, the first slide 31 and the second slide 32 have engaging portions 33. When the optical cable fixing and protection device is not subjected to external force, the movable end 12 of the first component and the movable end 22 of the second component are respectively engaged in the engaging portions 33 of the first slide 31 and the second slide 32. When the external force exceeds a certain threshold, the movable end 12 of the first component and the movable end 22 of the second component break through the limit of the engaging portions 33 and generate displacement. The engaging portions ensure that the movable ends are initially assembled in the slide 31 away from the outer side of the optical cable, ensuring that the movable ends have displacement space when subjected to external force.

It is not intended to be exhaustive or to limit the invention to a single disclosed embodiment. As mentioned above, various alternatives and variations of the present invention will be apparent to those skilled in the art. Therefore, while some alternative embodiments have been specifically discussed, other embodiments will be obvious or readily apparent to those skilled in the art.

[0025] Although the present invention has been described by way of embodiments, those skilled in the art will know that the present invention has many modifications and variations without departing from the spirit of the present invention, and the appended claims cover such modifications and variations without departing from the spirit of the present invention.
