A distributed cable body temperature measuring device

Abstract

The utility model discloses a distributed cable body temperature measuring device, which relates to the technical field of cable temperature measurement, and comprises a shell body. The shell body is a split structure, and a mounting port is opened on the shell body. A plurality of clamping plates are arranged inside the shell body, and a half gear is arranged on each clamping plate. The output shaft of a driving motor drives a clamping plate to rotate, and then the half gears on the two clamping plates mesh with each other, so that the two clamping plates are relatively rotated, and the cable is fixed between the two clamping plates. The cable tie on the clamping plate is affected by the relative rotation and extrusion of the two clamping plates, so that the cable tie gradually fits with the outer surface of the cable. In this process, the cable tie pulls the temperature measuring optical fiber to make it fit closely with the outer surface of the cable, thereby avoiding the situation that the cable tie is unevenly tied, and then the automatic bundling work can be realized, so as to improve the bundling tightness and bundling efficiency, which is beneficial to the feedback of the actual temperature of the cable.

Technical Field

[0001] The utility model relates to the technical field of cable temperature measurement, in particular to a distributed cable body temperature measurement device. Background Art

[0002] With the development of optical fiber application technology, the optical fiber temperature measurement system is currently the most advanced and effective continuous distributed temperature monitoring system in the world. It has been widely used in power systems. It is used to perform online real-time temperature monitoring of power cables. Its continuous, real-time and distributed temperature monitoring can accurately capture abnormal hot spots in cables, eliminate cable fires in the bud, and ensure the safe and healthy operation of the entire system.

[0003] At present, when the cable body temperature measuring device is installed with an external temperature measuring optical fiber, the temperature measuring optical fiber needs to be installed close to the detection area to achieve a rapid response to temperature or fire, and thus it is necessary to use a flame-retardant cable tie to bundle the temperature measuring optical fiber and the cable together. The traditional cable tie bundling method is usually done manually, which is prone to uneven tightness of the cable tie, which may cause uneven temperature distribution of the temperature measuring optical fiber monitoring cable, making it impossible for the temperature measuring optical fiber to accurately reflect the actual temperature of the cable.

[0012] Preferably, a slider is provided on the outer surface of the arc rod, a telescopic rod is evenly provided between the slider and the end of the arc rod away from the sealing plate, a return spring is provided between the slider and the end of the arc rod away from the sealing plate, and the return spring is sleeved on the outer surface of the arc rod.

[0013] Compared with the prior art, the utility model provides a distributed cable body temperature measuring device, which has the following beneficial effects:

[0014] The output shaft of the driving motor drives a clamping plate to rotate, and the mutual meshing action between the half gears on the two clamping plates causes the two clamping plates to rotate relative to each other, and the cable is fixed between the two clamping plates. The cable tie on the clamping plate is affected by the relative rotation and squeezing of the two clamping plates, so that the cable tie gradually fits the outer surface of the cable. In this process, the cable tie pulls the temperature measuring optical fiber to make it fit tightly with the outer surface of the cable, thereby avoiding the situation where the cable tie is unevenly tied, and then automatic bundling can be realized, thereby improving the bundling tightness and bundling efficiency, which is beneficial to the feedback of the actual temperature of the cable.

[0015] By injecting and extracting air into the air inlet pipe through an external fan, the sealing plate can push and pull the arc rod, thereby pulling the cable tie to the specified position, and then the pushing plate is driven by the pushing cylinder to push the cable tie into the storage groove on the clamping plate, thereby realizing automatic bundling of the cable tie, which can greatly speed up the bundling speed, reduce the time and cost of manual operation, and thus significantly improve production efficiency. At the same time, it can also ensure the tightness and uniformity of the bundling, and reduce the errors and differences caused by human operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The utility model is further described in detail below based on the drawings and embodiments.

[0027] Example

[0028] Please refer to Figures 1 to 4As shown, in order to solve the problems mentioned in the technical solution, an embodiment of the present application provides a distributed cable body temperature measuring device, including a shell 1, and the shell 1 is a split structure, wherein the shell 1 is composed of two symmetrical parts, and the two parts are detachable, and the two parts are connected to each other by snap fastening, so that the shell 1 can be quickly installed on the outer surface of the cable, and a mounting port 2 is opened on the shell 1, and a plurality of snap-fit ​​plates 5 are arranged inside the shell 1, each snap-fit ​​plate 5 is provided with a half gear 7, and a drive motor 4 is arranged inside the shell 1, and the output shaft of the drive motor 4 is connected to the rotating shaft on one of the snap-fit ​​plates 5; a feeding assembly is arranged inside the shell 1, which is used to convey the cable tie to the snap-fit ​​plate 5, wherein the shell 1 is formed by snapping together two parts, which is convenient for workers to quickly install it on the outer surface of the cable, and is conducive to the subsequent bundling of the temperature measuring optical fiber and the cable.

[0029] It is worth mentioning that the snap-fitting plate 5 is in an arc shape, which is used to better fit the cable surface, and the arc-shaped snap-fitting plate 5 can squeeze the cable tie to cause it to deform, thereby facilitating the subsequent snap-fitting of the two ends of the cable tie. In addition, the half gears 7 are meshed with each other and are symmetrically distributed around the central axis of the mounting port 2, which is used to ensure relative movement between the snap-fitting plates 5, so that the two ends of the cable tie can be close to each other and can make the cable tie fit the cable body more closely, thereby avoiding the situation where the uneven tightness of the cable tie leads to inaccurate temperature monitoring by the temperature measuring optical fiber; in addition, a storage groove 6 is provided on the inner surface of each snap-fitting plate 5, which is used to limit the movement range of the cable tie, prompting the cable tie to be placed inside it, and the two sides of the cable tie are in contact with The storage grooves 6 are in close contact with each other to avoid the situation where the front and rear ends of the cable tie are not aligned and cannot be bundled, and an anti-slip pad is arranged inside the storage groove 6 to prevent the cable tie from slipping during the bundling process, so that the cable tie can be firmly placed in the storage groove 6; at the same time, guide balls 3 are evenly arranged inside the installation port 2, which are used for the shell 1 to move along the outer surface of the cable, so that workers can quickly bundle the cable and the temperature measuring optical fiber, thereby improving the bundling work efficiency, and a limiting groove 19 is provided on the installation port 2 to limit the movement range of the temperature measuring optical fiber, thereby avoiding the situation where the temperature measuring optical fiber is offset during the bundling process and cannot fit tightly with the outer surface of the cable.

[0030] Further examples:

[0031] Please refer to Figures 2 to 5As shown, the feeding assembly includes a feeding trough 12, which is located on one side of the top of the shell 1, and a pushing cylinder 8 is evenly arranged on one side of the feeding trough 12 through an opened groove, and a pushing plate 10 is arranged at one end of the pushing cylinder 8, and a limiting rod 9 is arranged on one side of the pushing plate 10, which is used to assist the pushing plate 10 to shift the cable tie, and the pushing plate 10 is fitted with the feeding trough 12, which is used to ensure that the cable tie can be pushed onto the clamping plate 5 to prevent the position of the cable tie from being offset and affecting the subsequent bundling work, and a feeding hopper 11 is arranged on the top of the feeding trough 12, which is used to facilitate workers to quickly feed.

[0032] In addition, an air inlet pipe 13 is provided on the other side of the top of the shell 1, and the air inlet pipe 13 is located inside the feed trough 12. A sealing plate 14 is provided on the inner surface of the air inlet pipe 13, and an arc-shaped rod 15 is provided on one side of the sealing plate 14, which is used to pull and assist the cable tie to move along the inside of the feed trough 12, so that the cable tie can slide completely into the feed trough 12; at the same time, a slider 16 is provided on the outer surface of the arc-shaped rod 15, and telescopic rods 17 are evenly provided between the slider 16 and the end of the arc-shaped rod 15 away from the sealing plate 14, and a return spring 18 is provided between the slider 16 and the end of the arc-shaped rod 15 away from the sealing plate 14, and the return spring 18 is sleeved on the outer surface of the arc-shaped rod 15, wherein the telescopic rods 17 can be folded and rotated, and then the clamping and releasing of one end of the cable tie can be realized by its own rotation, so that the cable tie can be pulled to the specified position, which can be beneficial to the subsequent docking and clamping processing of the front and rear ends of the cable tie.

[0033] Everything in the above example works like this:

[0034] When in use, the two parts of the shell 1 are buckled onto the outer surface of the cable, and the temperature measuring optical fiber is placed inside the limiting groove 19, so that the temperature measuring optical fiber is located directly below the cable, and the multiple guide balls 3 inside the installation port 2 are pressed against the outer surface of the cable, thereby causing the shell 1 to slide along the cable. Then the worker puts the cable tie from the feed hopper 11 into the feed trough 12, and then injects air into the air inlet pipe 13 through an external fan, so that the sealing plate 14 pushes the arc rod 15 to slide along the inner surface of the air inlet pipe 13. When the telescopic rod 17 contacts the inner wall of the cable tie head, the telescopic rod 17 is forced to rotate inward and tends to be straightened, and The return spring 18 is in an extended state, and then the telescopic rod 17 is extended into the cable tie head. The return spring 18 loses its restriction and returns to its original state, so that the foldable and rotatable telescopic rod 17 is clamped inside the cable tie head. Then the air in the air inlet pipe 13 is discharged, and the air pressure difference is used to cause the arc rod 15 to drive the cable tie to move into the feed trough 12. When the telescopic rod 17 moves to the orifice of the air inlet pipe 13, its orifice continuously squeezes the telescopic rod 17, causing it to rotate inward again and tend to a straight state. At this time, the telescopic rod 17 is separated from the inside of the cable tie head, and the cable tie head stops moving due to the restriction of the air inlet pipe 13. Then the telescopic rod 17 moves with the arc rod 15. The shaped rod 15 enters the air inlet pipe 13 again, thereby ensuring that the position of the cable tie will not deviate, so as to facilitate the subsequent docking and engagement of the front and rear ends of the cable tie. Subsequently, the pushing cylinder 8 is started, and under the action of the limit rod 9, the pushing plate 10 is urged to fit the inside of the feed trough 12 to push the cable tie into the storage groove 6 on the locking plate 5. At this time, the driving motor 4 is started again, and the output shaft of the driving motor 4 drives a locking plate 5 fixedly connected to it to rotate, and under the mutual meshing action between the half gears 7 on the two locking plates 5, the two locking plates 5 are urged to rotate relative to each other, thereby squeezing the cable tie inside the storage groove 6. Under the limit groove 19, the temperature measuring optical fiber inside the limit groove 19 can be pulled upward and fit against the outer surface of the cable by bending the cable tie. The cable tie fits the temperature measuring optical fiber tightly against the lower position of the outer surface of the cable, while the two ends of the cable tie are not engaged with each other. As the two engaging plates 5 continue to move closer, the two ends of the cable tie gradually fit together. Since the cable tie is placed in the storage groove 6, the two ends of the cable tie are aligned with each other, and then the two ends can be engaged with each other. Under the gradual squeezing action of the two engaging plates 5, the inner diameter of the cable tie continues to shrink, and then the temperature measuring optical fiber and the cable can be bundled together, so that the temperature measuring optical fiber and the cable can fit tightly.
