Description

Technical Field

[0001] This invention relates to the field of temperature-sensing fiber optic installation technology, and in particular to a temperature-sensing fiber optic pre-winding device. Background Technology

[0002] Busbar fiber optic temperature measurement technology is based on the principle of fiber optic sensing, utilizing the optical signal transmission characteristics in optical fibers to measure temperature. When the ambient temperature of the fiber changes, the transmission characteristics of the optical signal also change accordingly. By detecting these changes, the real-time temperature of the busbar can be measured.

[0003] Currently, the common method for installing temperature-sensing optical fibers on busbars is to directly bundle the fiber with cable ties, making contact between the fiber and the busbar. However, in specific situations, it is necessary to focus on monitoring the temperature at the busbar connection point. In this case, the fiber is coiled around the busbar connection point multiple times, and the coiled fiber loops are fixed with high-temperature resistant tape. Monitoring the temperature at the busbar connection point is done by coiling the fiber. During the coiling process, the entire fiber at one end needs to be coiled around the busbar connection point. This process is all done manually, which is quite tedious and laborious for workers. Furthermore, there are usually multiple busbar connection points on a single line, requiring workers to perform the coiling operation multiple times, further increasing the difficulty of construction. Summary of the Invention

[0004] The main objective of this invention is to propose a temperature-measuring optical fiber pre-winding device, which aims to automate the pre-winding of optical fibers before they are laid, thereby greatly reducing the difficulty and construction time of optical fiber laying.

[0005] To achieve the above objectives, the temperature-measuring fiber optic pre-winding device proposed in this invention includes:

[0006] A frame, comprising a chassis and a frame body, wherein a fixing sleeve is provided protruding from one side of the frame body;

[0007] The fiber optic tray is located on one side of the frame and is rotatably connected to the inner wall of the fixed sleeve.

[0008] A winding mechanism includes a drive mechanism, a rotating frame, and a winding disc. The rotating frame is rotatably disposed on the outer wall of the fixed sleeve and extends toward the outer periphery of the optical fiber disc. The winding disc is connected to the end of the rotating frame and is located at the outer periphery of the optical fiber disc. The drive mechanism is used to drive the rotating frame to rotate around the fixed sleeve as an axis, so that the winding disc rotates around the optical fiber disc.

[0009] A guide ring is fixed to the chassis and surrounds the fiber optic disc. The winding disc is located inside the guide ring. The inner side of the guide ring has an inclined surface facing away from the frame. The side of the guide ring away from the frame is more prominent than the side of the fiber optic disc, and the side of the winding disc away from the frame is more prominent than the side of the guide ring.

[0010] In one embodiment, the temperature-measuring fiber pre-winding device further includes a pusher located on the side of the winding disc near the frame. The drive mechanism is used to drive the pusher to move toward the winding disc to push the fiber coil wound on the winding disc out of the winding disc.

[0011] In one embodiment, the drive mechanism is mounted on the frame, and the drive mechanism includes:

[0012] Drive motor;

[0013] The first gear is sleeved on the fixed sleeve and fixed to the rotating frame;

[0014] The second gear is located below the first gear and meshes with the first gear. The second gear is fixed to the drive motor. The second gear has only half a circle of teeth. The second gear has half a circle of teeth on the side of the second gear closest to the drive motor.

[0015] The third gear meshes with a half-circle tooth on one side of the second gear;

[0016] The fourth gear is located directly below the third gear and on one side of the winding disc. The fourth gear is connected to the third gear via a rotating shaft and has only half a tooth.

[0017] A guide frame and a sliding toothed frame, wherein the sliding toothed frame is slidably disposed on the guide frame, and teeth are provided on the two opposite inner sides of the sliding toothed frame; the fourth gear meshes with two teeth of the sliding toothed frame; and the pusher is connected to one side of the sliding toothed frame.

[0018] The drive motor drives the second gear to rotate. When the half-circle tooth of the second gear engages with the first gear, the first gear drives the rotating frame and the winding disc to rotate around the optical fiber disc, so as to wind the optical fiber onto the winding disc. When the half-circle tooth of the second gear disengages from the first gear, the half-circle tooth on the side of the second gear engages with the third gear. The second gear drives the third gear and the fourth gear to rotate. The fourth gear engages with the teeth on one side of the sliding tooth frame, so as to drive the sliding tooth frame and the pusher to move toward the winding disc, so as to push the optical fiber loop wound on the winding disc out of the winding disc. The fourth gear continues to rotate to engage with the teeth on the other side of the sliding tooth frame, so as to drive the sliding tooth frame and the pusher to reset.

[0019] In one embodiment, a half-turn tooth of the second gear can drive the first gear to rotate two or three times.

[0020] In one embodiment, a half-circle tooth on one side of the second gear can drive the third gear to rotate one revolution.

[0021] In one embodiment, a plurality of clearance grooves are uniformly formed on the outer wall surface of the winding disc.

[0022] In one embodiment, the end of the rotating frame is connected to the upper side of the winding disc, the pusher is an annular structure with a notch, the notch is used to make way for the end of the connecting frame, and the inner ring diameter of the pusher is the same as the diameter of the winding disc.

[0023] In one embodiment, the pusher has a chamfered angle on the side facing the winding disc.

[0024] In one embodiment, the temperature-measuring fiber pre-winding device further includes a discharge rack located on one side of the guide ring. The discharge rack is equipped with a fixing device for fixing the discharged fiber when the winding disc rotates.

[0025] The technical solution provided by this invention includes a temperature-measuring optical fiber pre-winding device comprising a frame, an optical fiber disc rotatably mounted on the frame, a winding mechanism, and a guide ring. The winding mechanism includes a drive mechanism, a rotating frame, and a winding disc. The drive mechanism drives the winding disc to rotate around the optical fiber disc. Combined with the guide ring having an inclined surface, during the optical fiber winding process, one end of the optical fiber can be guided to the outside, preventing the completed winding section from being wound onto the winding disc, thus ensuring that the optical fiber can be wound onto the winding disc normally. This configuration realizes an automated optical fiber pre-winding process. During optical fiber laying, it is only necessary to loop the optical fiber onto the busbar, eliminating the need for further winding operations, greatly reducing the difficulty and construction time of optical fiber laying.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0036] In the existing technology, during the construction of fiber optic cable laying and busbar winding, the entire fiber optic cable coiled at one end needs to be wrapped around the busbar connection point. This process is all done manually, which is tedious and laborious for workers. In addition, there are usually multiple busbar connection points in a line, requiring workers to perform the coiling operation multiple times, which further increases the difficulty of construction.

[0037] To address this technical problem, the present invention provides a temperature-measuring optical fiber pre-winding device 1000 to solve the problem of high difficulty for workers in winding optical fibers.

[0038] Please see Figures 1 to 3 The temperature-measuring fiber optic pre-winding device 1000 includes:

[0039] The frame 1 includes a chassis 11 and a frame 12, and a fixing sleeve 13 is provided on one side of the frame 12.

[0040] Fiber optic tray 2 is located on one side of the frame 12 and is rotatably connected to the inner wall of the fixed sleeve 13.

[0041] The winding mechanism 3 includes a drive mechanism 31, a rotating frame 32, and a winding disc 33. The rotating frame 32 is rotatably mounted on the outer wall of the fixed sleeve 13 and extends toward the outer periphery of the fiber optic disc 2. The winding disc 33 is connected to the end of the rotating frame 32 and is located at the outer periphery of the fiber optic disc 2. The drive mechanism 31 is used to drive the rotating frame 32 to rotate around the fixed sleeve 13 as the axis, so that the winding disc 33 rotates around the fiber optic disc 2.

[0042] Guide ring 4 is fixed to the chassis 11 and surrounds the fiber optic disk 2. The winding disk 33 is located inside the guide ring 4. The inner side of the guide ring 4 has an inclined surface that is away from the frame 12. The side of the guide ring 4 away from the frame 12 is more prominent than the side of the fiber optic disk 2. The side of the winding disk 33 away from the frame 12 is more prominent than the side of the guide ring 4.

[0043] The temperature-measuring fiber optic pre-winding device 1000 of this solution includes a frame 1, a fiber optic coil 2 rotatably mounted on the frame 1, a winding mechanism 3, and a guide ring 4. The winding mechanism includes a drive mechanism 31, a rotating frame 32, and a winding coil 33. The drive mechanism 31 drives the winding coil 33 to rotate around the fiber optic coil 2. Combined with the guide ring 4, which has an inclined surface, during the fiber winding process, one end of the fiber can be guided to the outside, preventing the completed winding section from being wound onto the winding coil 33, thus ensuring the fiber can be wound onto the winding coil 33 normally. After the fiber optic coil 2 is wound, the fiber coil is manually bound with high-temperature resistant tape, then removed from the winding coil 33. The completed winding section of the fiber is then pulled to the required length manually or by machine before the next winding operation. This setup realizes an automated fiber optic pre-winding process. During fiber laying, only the fiber coil needs to be placed on the busbar; no further winding is required, greatly reducing the difficulty and construction time of fiber optic laying.

[0044] The temperature measuring fiber pre-winding device 1000 also includes a take-up reel (not shown), which is located on one side of the guide ring 4. The take-up reel is used to pull out and store the completed section of the fiber winding.

[0045] In the technical solution provided by this invention, the temperature-measuring optical fiber pre-winding device 1000 further includes a pushing member 5, which is located on the side of the winding tray 33 near the frame 12. The driving mechanism 31 is used to drive the pushing member 5 to move toward the winding tray 33, so as to push the optical fiber loop wound on the winding tray 33 out of the winding tray 33. This reduces the manual operation process, saves labor costs, and improves the automation level of the product.

[0046] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the driving mechanism 31 includes two driving members, one driving member is used to drive the rotating frame 32 to rotate, and the other driving member is used to drive the pusher 5 to push toward the winding disk 33.

[0047] In another embodiment, the drive mechanism 31 is mounted on the frame 12, and the drive mechanism 31 includes:

[0048] Drive motor 311;

[0049] The first gear 312 is sleeved on the fixed sleeve 13 and fixed to the rotating frame 32;

[0050] The second gear 313 is located below the first gear 312 and meshes with the first gear 312. The second gear 313 is fixed to the drive motor 311. The second gear 313 is only provided with half a circle of teeth. The second gear 313 is provided with half a circle of teeth on the side of the second gear 313 closest to the drive motor 311.

[0051] The third gear 314 meshes with a half-circle tooth on one side of the second gear 313;

[0052] The fourth gear 315 is located directly below the third gear 314 and on one side of the winding disc 33. The fourth gear 315 is connected to the third gear 314 through a rotating shaft. The fourth gear 315 is only provided with half a circle of teeth.

[0053] The guide frame 316 and the sliding tooth frame 317 are slidably disposed on the guide frame 316. The two inner sides of the sliding tooth frame 317 are provided with teeth. The fourth gear 315 meshes with two teeth of the sliding tooth frame 317. The pusher 5 is connected to one side of the sliding tooth frame 317.

[0054] In this system, the drive motor 311 drives the second gear 313 to rotate. When the half-circle tooth of the second gear 313 engages with the first gear 312, the first gear 312 drives the rotating frame 32 and the winding disc 33 to rotate around the optical fiber disc 2, thereby winding the optical fiber onto the winding disc 33. When the half-circle tooth of the second gear 313 disengages from the first gear 312, the winding disc 33 returns to the position corresponding to the pusher 5. At this time, the worker uses high-temperature resistant tape to bind the optical fiber loop, and then restarts the drive motor 311. The half-circle tooth on the side of the second gear 313 engages with the third gear 314. The half-circle tooth on the side of the second gear 313 drives the third gear 314 and the fourth gear 315 to rotate. The fourth gear 315 engages with the teeth on one side of the sliding gear frame 317 to drive the sliding gear frame 317 and the pusher 5 to move towards the winding disk 33, so as to push the optical fiber coil wound on the winding disk 33 out of the winding disk 33. The fourth gear 315 continues to rotate to engage with the teeth on the other side of the sliding gear frame 317, so as to drive the sliding gear frame 317 and the pusher 5 to reset. At this time, the optical fiber coil pushed out of the winding disk 33 can be pulled out a predetermined distance to repeat the above winding and pushing operation.

[0055] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the half-circle tooth of the second gear 313 can drive the first gear 312 to rotate two or three times. The number of rotations of the first gear 312 is the number of rotations of the winding disk 33 around the optical fiber disk 2, and the number of rotations of the winding disk 33 around the optical fiber disk 2 is the number of times the optical fiber is wound onto the winding disk 33. Generally speaking, two or three turns of optical fiber winding is more in line with the detection setting.

[0056] In this embodiment, the half-circle tooth on one side of the second gear 313 can drive the third gear 314 to rotate one revolution. That is, during the process of winding, pushing and resetting, the fourth gear 315 will only rotate one revolution. One revolution is enough to drive the sliding gear frame 317 to move back and forth once, thus completing the pushing and resetting steps.

[0057] In one embodiment of the present invention, a plurality of clearance grooves 331 are uniformly formed on the outer wall surface of the winding disc 33. The clearance grooves 331 allow workers to use high-temperature resistant tape to bind the fiber coil after the optical fiber is wound onto the winding disc 33 and before the pusher 5 pushes it, making the operation relatively simple.

[0058] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the end of the rotating frame 32 is connected to the upper side of the winding disc 33. The pusher 5 is an annular structure with a notch, the notch being used to allow space for the end of the connecting frame. The inner ring diameter of the pusher 5 is the same as the diameter of the winding disc 33. By connecting the end of the rotating frame 32 to the upper side of the winding disc 33, more space is provided for the pusher 5 below. While ensuring that the pusher 5 does not obstruct the normal rotation of the rotating frame 32, the height of the pusher 5 is kept as high as possible to ensure that the pusher 5 can push the entire optical fiber coil, rather than only the lower half of the optical fiber coil.

[0059] In this embodiment, the pusher 5 has a chamfer on the side facing the winding disc 33. After the winding disc 33 is wound, it may not return to the position corresponding to the pusher 5, and there may be a slight positional deviation. By setting a chamfer on one side of the winding disc 33, this defect can be well compensated.

[0060] Please see Figure 1 In one embodiment of the present invention, the temperature-measuring optical fiber pre-winding device 1000 further includes a feeding rack 6, which is located on one side of the guide ring 4. The feeding rack 6 is equipped with a fixing device (not shown), which is used to fix the already fed optical fiber when the winding disc 33 rotates. By setting the fixing device, the already fed optical fiber is fixed, avoiding the already bundled optical fiber loop from being stretched too tightly during the winding process, which would cause the optical fiber loop to deform and affect the finished product.

[0061] In this embodiment, the fixing device is a clamp that fixes the optical fiber by clamping it.

[0062] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
