DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to specific implementation methods.

[0025] like Figure 1-5 As shown, a device for taking out an optical cable for a well includes a base, a large cable drum, a small cable drum, a cable drum shaft and a telescopic clamp; the number of the large cable drum, the small cable drum and the cable drum shaft is two, the two large cable drums are rotatably connected to the two cable drum shafts respectively, and the two small cable drums are rotatably connected to the two cable drum shafts respectively, and the two cable drum shafts are fixedly connected to the base, and the two cable drum shafts are arranged at intervals, located in the large cable drum and the small cable drum of the same cable drum shaft, and the small cable drum is located between the base and the large cable drum; a self-locking mechanism is provided between the two large cable drums and the two cable drum shafts to limit the reversal of the large cable drum, and a rebound mechanism is provided between the two large cable drums and the two cable drum shafts to provide rotational force for the large cable drum; the telescopic clamp is installed on the base, and the telescopic clamp is located between the two cable drum shafts; the optical cable is wound around the large cable drum, the optical cable is wound around the telescopic clamp, and the optical cable is wound around the small cable drum, and the winding directions of the optical cable and the two large cable drums are opposite.

[0026] In this embodiment, the two large wire reels are respectively the first large wire reel and the second large wire reel, and the two small wire reels are respectively the first small wire reel and the second small wire reel. The optical cable is wound around the first large wire reel, the first small wire reel, the telescopic clamp, the second small wire reel and the second large wire reel in sequence, wherein the winding direction of the optical cable is opposite to that of the first large wire reel and the second large wire reel, and the winding direction of the optical cable is opposite to that of the first small wire reel and the second small wire reel.

[0027] The large wire drum includes a large drum and two first guard plates, and the two first guard plates are respectively fixed to the two end edges of the large drum; the interior of the large drum is hollow, and one end of the large drum is provided with a first opening connected to the interior of the large drum, and the other end of the large drum is provided with a first connecting hole connected to the interior of the large drum, one end of the wire drum shaft passes through the first connecting hole and extends into the interior of the large drum, and the wire drum shaft and the first connecting hole are rotatably connected; the rebound mechanism is located in the large drum, one end of the rebound mechanism is fixed to the inner wall of the large drum, and the other end of the rebound mechanism is fixed to the wire drum shaft; one end of the self-locking mechanism is fixed to the first connecting hole, and the other end of the first self-locking mechanism is fixed to the wire drum shaft, and the optical cable is wound around the large drum.

[0028] The rebound mechanism is a rebound spring, one end of the rebound spring is fixed to the inner wall of the large drum, and the other end of the rebound spring is fixed to the reel shaft.

[0029] The self-locking mechanism includes a self-locking spring, a locking clip, and a toothed clip. The toothed clip is fixed in the first connecting hole. One end of the self-locking spring is fixed to the spool shaft, and the other end of the self-locking spring is fixed to one end of the locking clip. The other end of the locking clip presses against the toothed clip. The toothed clip is a helical gear. Because the self-locking spring continuously applies a thrust, the locking clip constantly presses against the toothed clip. Since the toothed clip is a helical gear, if it is reversed, the locking clip will jam the helical gear, preventing the large drum from rotating, thus achieving self-locking and limiting rotation to a single direction.

[0030] The first guard plate is an annular plate with a first through hole in the middle. The large roller is a cylindrical roller. The diameter of the first through hole is equal to the outer diameter of the large roller.

[0031] The small wire drum includes a small roller and two second guard plates, which are respectively fixed to the two end edges of the small roller; the small roller is provided with a second connecting hole, which passes through the small roller along the axis of the small roller, and one end of the wire drum shaft passes through the second connecting hole and extends into the interior of the large roller, and the wire drum shaft is rotatably connected to the second connecting hole; the optical cable and the small roller are wound.

[0032] The second guard plate is a frustum structure with a gradually decreasing radius. A second through hole is provided in the middle of the second guard plate. The small roller is a cylindrical roller. The diameter of the second through hole is equal to the outer diameter of the small roller.

[0033] The telescopic clamp includes four chucks, four telescopic springs and a fixed block. The fixed block is fixed on the base. The four telescopic springs are evenly distributed along the circumference of the fixed block. The four telescopic springs are fixedly connected to the fixed block. The four telescopic springs are distributed and fixedly connected to the four chucks. The optical cable and the chuck are wrapped around.

[0034] The outer end of the chuck is provided with a wire clamping groove, and the optical cable is wound around the wire clamping groove.

[0035] The base is a flat plate structure.

[0036] In this embodiment, a return spring increases the rotational force of the large reel, keeping the optical cable taut at all times. The initial design rotational force is 100N. A self-locking mechanism prevents the large reel from rotating, facilitating maintenance and tightening. When the large or small reel rotates, excess optical cable flows out. The retractable clamp opens to coil the excess cable around it.

[0037] An 11m optical cable margin is reserved on the large and small reels on the left and right sides respectively. The large and small reels are wound in opposite directions. During use, when the optical cable on either side is pulled, the two large and small reels on that side move together and rotate one circle at the same time. Due to the difference in diameters of the two large and small reels, the lengths of the released optical cables are different. Finally, after the large reel has released 10m of optical cable, the small reel only releases 1m of optical cable. The 1m optical cable is placed in the telescopic clamp by opening it, which does not affect the winding and tightening of the optical cable on the other side, thereby achieving the effect of flexible access to reserved optical cables of any length.

[0038] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
