Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, specifically to an auxiliary device for laying optical cables for monitoring reservoir panels. Background Technology

[0002] The reservoir basin project of a pumped storage hydropower station is a core component of the station, and its construction quality directly affects the station's water storage capacity, operational safety, and efficiency. Among these aspects, seepage prevention is crucial, and common construction methods include concrete panel seepage prevention, asphalt concrete seepage prevention, and clay seepage prevention.

[0003] In existing seepage prevention projects, the laying of concrete and asphalt panels relies heavily on workers' experience, leading to low efficiency, significant quality fluctuations, and high safety risks. To improve efficiency and quality stability due to reliance on manual labor, current solutions involve intelligent compaction using unmanned compaction equipment. However, this technology requires not only acquiring multiple compaction parameters from the unmanned equipment but also real-time monitoring of the dam's condition to flexibly adjust parameters such as speed and frequency. When monitoring the dam's condition, high-density strain sensors need to be laid in stress concentration areas like the dam foundation and easily deformable areas like the slopes. Current options include monitoring optical cables incorporating fiber optic strain sensors, but the sloping nature of the dam slopes makes laying these cables cumbersome.

[0004] Based on the above background, the applicant has designed an auxiliary device for laying optical cables for monitoring reservoir panels to solve the above problems, and hereby submits this application. Summary of the Invention

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 3 As shown, this embodiment provides an auxiliary device for laying optical cables for monitoring the reservoir panel, including a cable take-up and drop assembly for installation on the top of the reservoir and a cable turning assembly 9 for installation on the bottom of the reservoir, as well as a guide cable 5.

[0036] The take-up and unwind assembly includes a rotating shaft 3 and two identical wire reels 4 mounted on the rotating shaft 3, and also includes a drive structure for driving the rotating shaft 3 to rotate.

[0037] The guide cable 5 is provided with at least one optical cable fixing clip 51. One end of the guide cable 5 is connected to one of the cable reels 4, and the other end is connected to another cable reel 4 after passing around the steering component.

[0038] This embodiment, by setting up a cable reel-in / deel-out assembly, a cable turning assembly 9, and a guide cable 5, allows the guide cable 5 to be released through the cable reel-in / deel-out assembly, turned by the cable turning assembly 9, and then retracted. The guide cable 5 is also equipped with an optical cable fixing clip 51, which can fix the end of the monitoring optical cable. Then, the guide cable 5 moves from the top of the reservoir to the bottom of the reservoir, and then the operator can directly lay the optical cable on the inclined slope. Therefore, through the cooperation of the above components, this embodiment eliminates the need for manual pulling of the monitoring optical cable when laying it, resulting in high laying efficiency and good construction safety. It can effectively solve the problem of difficulty in laying monitoring optical cables on inclined slopes in the prior art.

[0039] In this embodiment, the two reels 4 are used for taking in and releasing the line, respectively. Since both reels 4 are mounted on the rotating shaft 3, the guide wire 5 needs to be wound in opposite directions when it is wound on the two reels 4. When the rotating shaft 3 rotates and drives the two reels 4 to rotate synchronously, the guide wire 5 on the two reels 4 is in a state of taking in and releasing the line.

[0040] In this embodiment, a mounting frame 1 is also included, which includes a portal frame 11, a base plate 12, and a motor mounting base 13.

[0041] The portal frame 11 and the motor mounting base 13 are both mounted on the base plate 12;

[0042] The drive structure is a drive motor 2 mounted on a motor mounting base 13. The output shaft of the drive motor 2 is coaxially and fixedly connected to the rotating shaft 3 via a coupling. The end of the rotating shaft 3 away from the coupling is rotatably connected to the gantry frame 11. In this embodiment, the drive structure is a drive motor 2, which can reduce the labor intensity of laying monitoring optical cables.

[0043] In this embodiment, a pulley block 6 is also included, which includes a first pulley 61 and a second pulley 62 disposed on the top of the portal frame 11.

[0044] One end of the guide line 5 is connected to one of the line reels 4, and the other end is connected to another line reel 4 after passing through the first line pulley 61, the line steering assembly 9, and the second line pulley 62. By setting the first line pulley 61 and the second line pulley 62, the guide line 5 can be supported, preventing it from falling onto the slope surface when it is located in the middle of the reservoir slope.

[0045] In this embodiment, the first line pulley 61 and the second line pulley 62 are respectively located directly above the two line reels 4;

[0046] The top of the gantry frame 11 is also equipped with an optical cable pulley 8, which can support and guide the monitoring optical cable.

[0047] In this embodiment, the coil 4 includes a winding part 41 and a mounting part 42 that are fixedly connected;

[0048] The outer peripheral wall of the winding part 41 is provided with a winding annular groove for winding and coiling.

[0049] The inner peripheral wall of the mounting part 42 is provided with a plurality of rotation limiting grooves 421 that are axially connected along the disc 4;

[0050] The rotating shaft 3 is provided with two sets of rotation-limiting protrusions 301 that are adapted to the rotation-limiting grooves 421 on the two reels 4. By providing rotation-limiting grooves 421 on the mounting part 42 of the reel 4 and rotation-limiting protrusions 301 on the rotating shaft 3, the reel 4 can rotate synchronously with the rotating shaft 3 after being installed on it. When needed, the reel 4 can be moved laterally to other positions on the rotating shaft 3, so that the two reels 4 can simultaneously release or retract the line, thereby adjusting the distance between the line release / retract assembly and the line steering assembly 9 to adapt to different slope positions of the reservoir basin.

[0051] In this embodiment, the spool 4 further includes a plurality of connecting plates 43 distributed circumferentially along the mounting portion 42, and the winding portion 41 is fixedly connected to the mounting portion 42 through the connecting plates 43.

[0052] In this embodiment, a plurality of retaining ring mounting holes 422 are also provided on the two side walls of the mounting part 42;

[0053] It also includes an anti-slip ring 7 for preventing the rotation-limiting groove 421 of the reel 4 from sliding off the rotation-limiting protrusion 301. The anti-slip ring 7 is detachably fixed to the side wall of the mounting portion 42 via a ring mounting hole 422. By providing the ring mounting hole 422 and the anti-slip ring 7, it is possible to prevent the reel 4 from sliding off the rotation-limiting protrusion 301 of the shaft 3 when it rotates. In some embodiments, the anti-slip ring 7 can also be detachably connected to the mounting portion 42 of the reel 4 by snap-fit ​​or other means.

[0054] In this embodiment, the line steering assembly 9 includes a steering seat 91 for mounting to the bottom of the tank, and a steering pulley 92 mounted on the steering seat 91, with the guide cable 5 wound around the steering pulley 92. It also includes a bracket, through which the steering pulley 92 is mounted on the steering seat 91. In this embodiment, the steering seat 91 can be a metal counterweight base, and its placement facilitates the repositioning of the line steering assembly 9.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
