Description

Technical Field

[0001] The invention relates to the technical field of temperature measuring optical fiber installation, and in particular to a temperature measuring optical fiber pre-winding device. Background Art

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

[0003] At present, the installation method of temperature measuring optical fiber on the bus is generally to directly tie the optical fiber to the bus with a cable tie to make the optical fiber contact with the bus. However, in certain circumstances, it is necessary to focus on monitoring the temperature of the busbar connection. At this time, the optical fiber will be coiled around the busbar connection for multiple turns, and the multiple coiled optical fiber turns will be fixed with high-temperature resistant tape. The temperature of the busbar connection is focused on monitoring by coiling the optical fiber. During the coiling process, the entire optical fiber coil at one end needs to be coiled around the busbar connection. This process is all manual operation, which is cumbersome and laborious for workers. In addition, there are usually multiple busbar connection positions in a line, and workers are required to perform coiling operations multiple times, further increasing the construction difficulty for workers.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In the prior art, during the construction of laying and winding the optical fiber busbar, the entire optical fiber coil at one end needs to be wound around the busbar connection. This process is all manual, which is cumbersome and laborious for workers. In addition, there are usually multiple busbar connection positions in a line, and workers are required to perform the winding operation multiple times, further increasing the construction difficulty for workers.

[0037] In order to solve this technical problem, the present invention provides a temperature measuring optical fiber pre-winding device 1000 to solve the problem that it is difficult for workers to wind the optical fiber.

[0038] See also Figures 1 to 3 The temperature measuring optical fiber pre-winding device 1000 comprises:

[0039] The frame 1 comprises a chassis 11 and a frame body 12, and a fixing sleeve 13 is protruding from one side of the frame body 12;

[0040] The optical fiber tray 2 is located on one side of the frame 12 and is rotatably connected to the inner wall surface of the fixed sleeve 13;

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

[0042] The guide ring 4 is fixed to the chassis 11, and the guide ring 4 is arranged around the optical fiber reel 2. The winding reel 33 is located on the inner side of the guide ring 4. The inner side of the guide ring 4 is provided with an inclined surface facing away from the frame 12. The side of the guide ring 4 away from the frame 12 is more protruding than the side of the optical fiber reel 2, and the side of the winding reel 33 away from the frame 12 is more protruding than the side of the guide ring 4.

[0043] The temperature measurement optical fiber pre-winding device 1000 of the present scheme includes a frame 1, an optical fiber reel 2 rotatably arranged on the frame 1, a winding mechanism 3, and a guide ring 4. The winding mechanism includes a driving mechanism 31, a rotating frame 32, and a winding reel 33. The driving mechanism 31 drives the winding reel 33 to rotate around the optical fiber reel 2. Combined with the guide ring 4 provided with an inclined surface, during the optical fiber winding process, one end of the optical fiber can be guided to the outside, and the completed winding section of the optical fiber will not be wound together on the winding reel 33, so as to ensure that the optical fiber can be normally wound on the winding reel 33. After the optical fiber reel 2 is wound, the optical fiber coil is manually tied with a high temperature resistant tape, and then the optical fiber coil is removed from the winding reel 33, and then the completed winding section of the optical fiber is manually or mechanically pulled out to the required length for the next winding operation. Such a setting realizes the automatic pre-winding process of the optical fiber. When laying the optical fiber, it is only necessary to put the optical fiber coil on the busbar, and no winding operation is required, which greatly reduces the difficulty and construction time of laying the optical fiber.

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

[0045] In the technical solution provided by the present invention, the temperature measuring optical fiber pre-winding device 1000 further includes a pusher 5, which is located on the side of the winding disk 33 close to the frame 12, and the driving mechanism 31 is used to drive the pusher 5 to move toward the winding disk 33 to push the optical fiber loop wound on the winding disk 33 out of the winding disk 33. The manual operation process is reduced, the labor cost is saved, and the automation degree of the product is improved.

[0046] See also 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 pushing member 5 to push toward the winding disk 33.

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

[0048] Driving motor 311;

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

[0050] A second gear 313, 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 driving motor 311, the second gear 313 is only provided with a half circle of teeth, and a half circle of teeth is provided on a side of the second gear 313 close to the driving motor 311;

[0051] A third gear 314, the third gear 314 is meshed with a half circle of teeth 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 disk 33. The fourth gear 315 is connected to the third gear 314 via a rotating shaft. The fourth gear 315 is only provided with a half circle of teeth.

[0053] A guide frame 316 and a sliding gear frame 317, wherein the sliding gear frame 317 is slidably disposed on the guide frame 316, and teeth are disposed on two opposite inner sides of the sliding gear frame 317, and the fourth gear 315 is meshed with two teeth of the sliding gear frame 317, and one side of the sliding gear frame 317 is connected to the pusher 5;

[0054] The driving motor 311 drives the second gear 313 to rotate. When the half-circle teeth of the second gear 313 are in contact and mesh with the first gear 312, the first gear 312 drives the rotating frame 32 and the winding disk 33 to rotate around the optical fiber disk 2 to wind the optical fiber onto the winding disk 33. When the half-circle teeth of the second gear 313 are out of mesh with the first gear 312, the winding disk 33 is reset to the position corresponding to the pusher 5. At this time, the worker uses a high-temperature resistant tape to tie the optical fiber loop and starts the driving motor 311 again. The second gear 31 The half-circle teeth on the side of the second gear 313 are in contact and mesh with the third gear 314, and the half-circle teeth on the side of the second gear 313 drive the third gear 314 and the fourth gear 315 to rotate, and the fourth gear 315 is meshed 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 toward the direction of the winding disk 33, so as to push the optical fiber ring wound on the winding disk 33 out of the winding disk 33, and the fourth gear 315 continues to rotate to mesh with the teeth on the other side of the sliding gear frame 317 to drive the sliding gear frame 317 and the pusher 5 to reset. At this time, the optical fiber ring pushed out of the winding disk 33 can be pulled out a predetermined distance to repeat the above winding and pushing operations again.

[0055] See also Figure 2 and Figure 3 In one embodiment of the present invention, the half circle of teeth of the second gear 313 can drive the first gear 312 to rotate two or three circles. The number of circles of the first gear 312 is the number of circles of the winding disk 33 around the optical fiber disk 2, and the number of circles of the winding disk 33 around the optical fiber disk 2 is the number of circles of the optical fiber wound around the winding disk 33. Generally speaking, the optical fiber is wound two or three circles, which is more in line with the set number of circles for detection.

[0056] In this embodiment, the half circle of teeth on one side of the second gear 313 can drive the third gear 314 to rotate one circle. That is, in the process of one round of winding to push and reset, the fourth gear 315 will only rotate one circle, and one circle can drive the sliding gear frame 317 to go back and forth once, that is, the pushing and reset steps are completed.

[0057] In one embodiment of the present invention, a plurality of clearance grooves 331 are evenly arranged on the outer wall surface of the winding drum 33. The setting of the clearance grooves 331 allows workers to use high temperature resistant tape to pass through the clearance grooves 331 to bundle the optical fiber loop after the optical fiber is wound onto the winding drum 33 and before the pusher 5 is pushed, which is relatively easy to operate.

[0058] See also 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 disk 33, and the pusher 5 is a ring structure with a notch, and the notch is used to make way for the end of the connecting frame, and the inner ring diameter of the pusher 5 is consistent with the diameter of the winding disk 33. The end of the rotating frame 32 is set and connected to the upper side of the winding disk 33, so as to make more space for the setting of the pusher 5 below. Under the premise of ensuring that the pusher 5 does not stop the normal rotation of the rotating frame 32, the setting height of the pusher 5 is guaranteed as much as possible, so as to ensure that the pusher 5 can push the entire optical fiber loop instead of only the lower half of the optical fiber loop.

[0059] In this embodiment, the pusher 5 is provided with a chamfered angle on one side facing the winding disk 33. After the winding of the winding disk 33 is completed, the winding disk 33 may not be reset to the position corresponding to the pusher 5, and there may be a slight position deviation. By providing a chamfered angle on one side of the winding disk 33, this defect can be well compensated.

[0060] See also Figure 1 In one embodiment of the present invention, the temperature measuring optical fiber pre-winding device 1000 further includes a discharging rack 6, which is located on one side of the guide ring 4. The discharging rack 6 is provided with a fixing device (not shown), which is used to fix the discharged optical fiber when the winding disk 33 rotates. By providing the fixing device, the discharged optical fiber is fixed, which avoids the already bundled optical fiber loop being stretched and stretched during the winding process to cause the optical fiber loop to deform, thereby affecting the finished product effect.

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

[0062] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
