Description

Technical Field

[0001] The utility model relates to the field of optical fiber fixing frames, in particular to a universal temperature measuring optical fiber bracket. Background Art

[0002] Temperature-measuring optical fibers can provide real-time, continuous temperature monitoring over long distances, offering high temperature measurement accuracy and accurately reflecting even small temperature changes. They also offer distributed measurement capabilities, capable of simultaneously measuring the temperature at multiple points along the fiber's length, providing comprehensive temperature distribution information. Therefore, in large hydropower stations, temperature-measuring optical fibers are typically installed on the top layer of cables within the cable tray to form a fiber Bragg grating (FBG) temperature measurement system. This FBG temperature measurement system is then linked to the fire alarm system to monitor the temperature of power and control cables.

[0003] Compared with power cables or control cables, temperature measuring optical fibers have a smaller diameter and are easily damaged. In actual work, in order to meet the needs of equipment operation, it is often necessary to add or remove cables. Since the temperature measuring optical fibers need to be laid on the top layer of the cables, it is inevitable to move the temperature measuring optical fibers out of the cable tray when adding or removing cables, thereby increasing the risk of the temperature measuring optical fibers being twisted or broken. In addition, temperature measuring optical fibers are often laid over long distances. Once the temperature measuring optical fibers are damaged, re-laying them will increase the workload. Utility Model Content

[0004] In order to overcome the problem in the above-mentioned background technology that adding or removing cables requires moving the temperature measuring optical fiber out of the cable tray, thereby increasing the risk of the temperature measuring optical fiber being twisted or broken, the utility model provides a universal temperature measuring optical fiber bracket. By installing the temperature measuring optical fiber on a bracket that can arbitrarily bend and adjust the arrangement position of the temperature measuring optical fiber, the distribution position of the temperature measuring optical fiber can be freely adjusted without moving the temperature measuring optical fiber out of the cable tray, thereby avoiding damage to the temperature measuring optical fiber when adjusting the cable. The utility model has the beneficial effects of simple structure, compact size, wide application range, easy installation, cost saving, great construction flexibility, and improved efficiency of cable adjustment construction.

[0005] The technical solution of the utility model is as follows:

[0006] A universal temperature measuring optical fiber bracket includes a universal rod, which can be bent arbitrarily. A fixed ring is connected to the top of the universal rod, and the fixed ring is used to provide limited support for the temperature measuring optical fiber. The bottom of the universal rod is fixedly connected to the base, and the base is fixedly connected to the cable tray. The temperature measuring optical fiber is installed on the cable tray through several groups of brackets.

[0007] Compared with the existing technology, the beneficial effects of this technical solution are:

[0008] (1) The bracket is compact, light and easy to carry. Since the universal rod can be bent arbitrarily, it can be bent 360° in all directions according to the actual situation and construction conditions on site, and the temperature measuring optical fiber at that position can be adjusted to the most suitable position to meet the installation requirements of various angles without having to remove the temperature measuring optical fiber from the cable tray. Universal rods of different lengths can be used in conjunction with the base to meet the needs of cable trays with different layer spacings.

[0009] (2) This bracket solves the problem in the background technology that when adding or removing cables, the temperature measuring optical fiber needs to be removed from the cable tray, thereby increasing the risk of the temperature measuring optical fiber being twisted or broken. The bracket is installed on the cable tray where cables are frequently added or removed, which greatly reduces the risk of damage to the temperature measuring optical fiber, avoids increasing workload, and improves efficiency.

[0010] (3) This bracket is not only suitable for temperature measuring optical fibers, but also can be used for most secondary leads and network cables with smaller diameters to avoid damage caused by external forces.

[0011] Preferably, the fixing ring passes through the top end of the universal rod, and its broken connection portion is fixedly connected by a metal loose-leaf buckle.

[0012] Further preferably, the temperature measuring optical fiber directly passes through the fixing ring.

[0013] Preferably, the fixing ring is fixedly connected to the universal rod, and the temperature measuring optical fiber is connected to the fixing ring by binding.

[0014] Preferably, a threaded column perpendicular to the surface of the base is fixed in the middle of the base, and a threaded hole matching the threaded column is provided at the bottom of the universal rod, and the threaded column is fixedly connected to the threaded hole.

[0015] Further preferably, both sides of the base are provided with integrally connected connecting plates, and the connecting plates are fixedly connected to the cable tray by means of threaded connections.

[0016] Preferably, the brackets are laid on the cable tray in an "S" shape, and the spacing between adjacent brackets is 1.5-2m.

[0017] Preferably, the universal rod is made of carbon steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example 1: Figures 1 to 3 The illustrated universal temperature-sensing optical fiber bracket includes a flexible universal rod 1, which can be bent or straightened to adjust the position of the mounting component. A fixed ring 2 is connected to the top of the universal rod 1, which provides positional support for a temperature-sensing optical fiber 4. Specifically, the temperature-sensing optical fiber 4 is mounted on the top of the universal rod 1 via the fixed ring 2. Bending or straightening the universal rod 1 allows the position of the connection point of the temperature-sensing optical fiber 4 to be adjusted to meet practical needs. The bottom of the universal rod 1 is fixedly connected to a base 3, which is secured to the cable tray.

[0025] During use, first install the bases 3 of several brackets on the cable tray at intervals according to actual conditions, and then install the entire temperature-measuring optical fiber 4 on the fixing ring 2 of the brackets in sequence. That is, each temperature-measuring optical fiber 4 is installed on the cable tray through several groups of brackets to maintain the stability of the entire section of temperature-measuring optical fiber 4. When adding or removing power cables or control cables, straighten the brackets on the cable tray and bend them in the opposite direction of laying. The temperature-measuring optical fiber 4 is suspended on both sides of the cable tray through the brackets, maintaining a sufficient distance from the cable tray to avoid stretching or pinching the temperature-measuring optical fiber 4 when dragging or pulling new or old cables.

[0026] This bracket is small in size, light in weight and easy to carry. Since the universal rod 1 can be bent arbitrarily, the universal rod 1 can be bent 360° in all directions according to the actual situation and construction conditions on site, until the temperature measuring optical fiber 4 at that position is adjusted to the most suitable position to meet the installation requirements of various angles without having to move the temperature measuring optical fiber 4 out of the cable tray. Universal rods 1 of different lengths can be used in combination with the base 3 to meet the needs of cable trays with different layer spacings. This bracket solves the problem in the background technology that when adding or withdrawing cables, the temperature measuring optical fiber 4 needs to be moved out of the cable tray, thereby increasing the risk of the temperature measuring optical fiber 4 being twisted or broken. Installing this bracket on a cable tray where cables are frequently added or withdrawn can greatly reduce the risk of damage to the temperature measuring optical fiber 4, avoid increasing workload and improve efficiency. This bracket is not only suitable for the temperature measuring optical fiber 4, but most secondary leads and network cables with smaller diameters can also use this method to avoid damage caused by external forces.

[0027] Example 2: Based on Example 1, the fixing ring 2 is preferably designed as follows: Figures 1 to 2 As shown, the fixing ring 2 is a fractured circular ring structure, and a fixing hole 11 is provided at the top of the universal rod 1. The fixing ring 2 passes through the fixing hole 11 of the universal rod 1 and is circumferentially connected with the fixing hole 11. The fracture connection part 21 of the fixing ring 2 is fixedly connected by a metal loose-leaf buckle 22. Preferably, the metal loose-leaf buckle 22 made of aluminum alloy has high strength and toughness, and is lightweight and suitable for both indoor and outdoor use. When in use, it is only necessary to put the temperature measuring optical fiber 4 into the fixing ring 2, and the two loose-leafs are buckled together to achieve the purpose of fixing the optical fiber. This fixing method is fast and convenient to install, and it is firmly fixed after installation and easy to disassemble and assemble. In addition, the metal loose-leaf buckle 22 design is also suitable for different types of optical fibers, including single-mode and multi-mode optical fibers. When installing or removing the temperature measuring optical fiber 4, the temperature measuring optical fiber 4 can be directly inserted into or out of the fixing ring 2, or it can be inserted into or out of the fixing ring 2 from the opened fracture connection part 21. Therefore, the fixing ring 2 can be separated or closed by opening and closing the metal loose-leaf buckle 22 to remove or install the temperature measuring optical fiber 4, and the temperature measuring optical fiber 4 supported by multiple groups of brackets can be removed or installed partially, which is more convenient to use. This connection method has good connection stability and is easy to disassemble and assemble. After the temperature measuring optical fiber 4 is withdrawn, the bracket can still be used, thereby improving the utilization rate of the bracket.

[0028] Example 3: Based on Example 1, the connection method of the temperature measuring optical fiber 4 and the fixing ring 2 is optimally designed, such as Figure 3 As shown, the fixing ring 2 is a seamless (no break) circular ring structure and is welded and fixed to the universal rod 1. The temperature measuring optical fiber 4 is connected to the fixing ring 2 by binding. This connection method is simple to operate and the connection stability can also be guaranteed.

[0029] Example 4: Based on Example 1, the connection method of the universal rod 1 and the base 3 is preferably designed. A threaded column 31 perpendicular to the surface of the base 3 is fixed in the middle of the surface. A threaded hole matching the threaded column 31 is provided at the bottom of the universal rod 1. The threaded column 31 is fixedly connected to the threaded hole. During installation, the universal rod 1 is directly rotated and mounted on the base 3. The installation is simple. The universal rod 1 and the base 3 are connected in this detachable connection manner, which can not only ensure the installation stability during use, but also realize the single replacement of the universal rod 1 or the base 3. If any component of the base 3 or the universal rod 1 is damaged, only the damaged component can be replaced without replacing the entire component, thereby saving costs. In addition, universal rods 1 of different lengths can be selected according to the actual cable tray layer spacing on site to meet actual needs and increase the scope of application.

[0030] Furthermore, both sides of the base 3 are provided with integrally connected connecting plates 32, and threaded holes are provided in the connecting plates 32. Bolts pass through the threaded holes and are fixedly connected to the cable tray. By adopting this double-hole fixing method, the base 3 can be installed and fixed on the cable tray longitudinally or transversely, and the fixing method of the bracket is also stronger and more flexible.

[0031] Example 5: An optimal design is made based on Example 1. Since the universal rod 1 can be bent arbitrarily, it is bent to an appropriate position according to the arrangement of the on-site temperature measuring optical fiber 4 during use, so that the temperature measuring optical fiber 4 is laid in an "S" shape on the top layer of the cable, which can cover more cables on the bridge. The spacing between adjacent brackets is 1.5-2m, which can keep the entire section of temperature measuring optical fiber 4 stably connected. In actual use, the spacing between each bracket can be flexibly arranged according to the actual situation and construction conditions on site.

[0032] Furthermore, the universal rod 1 is made of carbon steel, which contains a certain proportion of carbon elements, so that it has high strength and can well support the weight of the temperature measuring optical fiber 4. There is no need to worry about the bracket being deformed or damaged due to being unable to bear the weight, and carbon steel has good wear resistance and fatigue resistance. When the bracket is in use, it is not easy for the universal rod 1 to be deformed or damaged due to bending or straightening adjustment or slight collision and friction. It has a long service life and good toughness, and can maintain good support even after bending or straightening.

[0033] The above embodiments merely represent specific implementation methods of the present application. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the technical concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
