Description

Technical Field

[0001] This utility model relates to the field of fiber optic temperature measurement technology, and in particular to a fiber optic temperature measurement device. Background Technology

[0002] In modern industry and scientific research, the demand for high-precision temperature monitoring is growing. Fiber optic temperature measurement technology, with its significant advantages such as resistance to electromagnetic interference, high precision, and long-distance transmission, is gradually becoming the preferred solution for temperature monitoring in many critical scenarios. For example, in power systems, temperature monitoring of critical components such as transformers, distribution cabinets, and transmission lines is directly related to the stability and security of power supply. In the petrochemical industry, real-time temperature control of equipment such as reactors and pipelines plays a decisive role in ensuring the safe operation of production processes and product quality. In these application scenarios, to achieve comprehensive and accurate temperature monitoring, it is necessary to uniformly cover the entire circuit or monitoring area with optical fibers.

[0003] However, many challenging problems arise when actually deploying fiber optic temperature measurement equipment.

[0004] 1) Traditional cable winding and management methods are difficult to meet the requirements of uniform fiber optic coverage. Common manual winding methods are not only inefficient, but also difficult to ensure the uniformity of fiber optics during winding and unwinding. Cable tangling and knotting are very likely to occur, which will not only affect the service life of fiber optics, but also make it impossible to accurately lay fiber optics to the designated location during cabling, thus affecting the accuracy and comprehensiveness of temperature measurement.

[0005] 2) Most of the existing cable take-up and management devices on the market are simple in design and lack targeted optimization for delicate cables such as optical fibers. They often cannot achieve precise control over the fiber take-up speed and management position, making it difficult to meet the stringent requirements for uniform fiber coverage under complex circuit layouts.

[0006] In addition, these devices are also inadequate in their coordination with fiber optic temperature measurement equipment. They cannot adjust the cable winding and management operations in real time according to the working status of the temperature measurement equipment, which greatly reduces the stability and reliability of the entire fiber optic temperature measurement system. Utility Model Content

[0007] The purpose of this invention is to solve the problems existing in the prior art, such as the low efficiency of traditional cable winding and management methods, the difficulty in ensuring uniform winding and unwinding of optical fibers, and the inability to accurately lay optical fibers during cabling. Therefore, this invention proposes an optical fiber temperature measurement device.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: It includes a device housing, the top of which has an optical fiber inlet and a sliding groove; a device host is fixedly connected inside the device housing; a winding mechanism is provided inside the device housing; the winding mechanism includes a rotating handle, one end of which is fixedly connected to a transmission disc; two winding rods are fixedly connected to the outer surface of the transmission disc; one end of each winding rod is fixedly connected to a quick-release connector; a first gear is movably sleeved on the outer surface of the quick-release connector; a first connecting rod is fixedly inserted into the outer surface of the first gear; and the sliding groove is the inlet for the optical fiber.

[0010] Preferably, a first sector gear is fixedly connected to the outer wall of the third gear, and a second sector gear is fixedly connected to the outer wall of the fourth gear.

[0011] Preferably, both the outer walls of the first sector gear and the second sector gear are meshed with racks.

[0012] Preferably, a sliding block is fixedly connected to the outer surface of the rack, a wire hole is fixedly connected to the outer surface of the rack, and a sliding groove is slidably connected to the outer wall of the sliding block.

[0013] Preferably, the outer walls of the first gear and the second gear mesh with each other, and one end of the first connecting rod is rotatably connected to the inner wall of the equipment housing.

[0016] Preferably, the outer wall of the rotating handle is movably inserted into the outer surface of the equipment housing.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, the innovatively designed winding mechanism, through the coordinated operation of the rotating handle, transmission disc, and winding rod, combined with the quick-release connector, achieves efficient and uniform winding and storage of optical fiber cables. Unlike traditional manual winding or simple winding devices, this winding mechanism uses the first gear and the first connecting rod to maintain operational stability, ensuring that the cable will not tangle or knot during the winding process. This greatly improves winding efficiency and quality, which not only saves wiring time but also ensures the integrity of the optical fiber in the subsequent laying process, effectively improving the accuracy of optical fiber temperature measurement equipment wiring, and thus improving the accuracy and comprehensiveness of temperature measurement.

[0019] 2. In this utility model, the unique translation mechanism, through a series of complex and precise gear transmissions, can accurately control the position movement of the threading hole, thereby achieving precise adjustment of the fiber optic cable position. In the actual deployment of fiber optic temperature measurement equipment, existing technologies often struggle to flexibly and accurately adjust the cable position according to the complex circuit layout. However, the translation mechanism of this utility model can easily solve this problem. Through the coordinated work of components such as worm gears, sector gears, and racks, it ensures that the threading hole drives the fiber optic cable to move smoothly and accurately, meeting the stringent requirements for uniform fiber optic coverage in different circuit wiring scenarios. In addition, the translation mechanism and the winding mechanism achieve power transmission and linkage control through the meshing of the first and second gears, enabling the two mechanisms to cooperate with each other and adjust their operation in real time according to the working status of the fiber optic temperature measurement equipment, significantly enhancing the stability and reliability of the entire fiber optic temperature measurement system.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: Please refer to... Figures 1-6 As shown, this utility model provides, as Figure 1 As shown, it includes: a device housing 1, with an optical fiber inlet 11 and a sliding groove 12 on the top of the device housing 1, a device host 13 fixedly connected inside the device housing 1, and a winding mechanism 3 inside the device housing 1; the winding mechanism 3 includes a rotating handle 301, a transmission disc 302 fixedly connected to one end of the rotating handle 301, two winding rods 303 fixedly connected to the outer surface of the transmission disc 302, quick-release connectors 304 fixedly connected to one end of the two winding rods 303, a first gear 305 movably sleeved on the outer surface of the quick-release connector 304, and a first connecting rod 306 fixedly inserted into the outer surface of the first gear 305.

[0030] The overall effect of Embodiment 1 is that rotating the handle 301 drives the transmission disc 302 to rotate smoothly. Since the winding rod 303 is fixed on the outer surface of the transmission disc 302, the winding rod 303 can rotate synchronously and at a uniform speed. The quick-release connector 304 facilitates the connection of optical fiber cables. During the winding process, the first gear 305 and the first connecting rod 306 work together to ensure the stability and smoothness of the rotation of the winding rod 303, so that the optical fiber cables can be wound evenly and orderly on the winding rod 303, avoiding cable accumulation or uneven winding. When it is necessary to rearrange the optical fiber, rotating the handle 301 in the opposite direction allows the cable to be quickly and evenly unwound.

[0031] Example 2: Please refer to... Figures 1-6 As shown, a translation mechanism 4 is provided inside the housing 1 of the equipment. The translation mechanism 4 includes a second connecting rod 402 fixedly inserted inside a second gear 401. A worm gear 403 is fixedly connected to the outer wall of the second connecting rod 402. A fifth gear 412 meshes with the outer wall of the worm gear 403. A fourth gear 405 is fixedly connected to the outer surface of the fifth gear 412 via a shaft. A third gear 404 meshes with the outer wall of the fourth gear 405. A first sector gear 406 is fixedly connected to the outer wall of the third gear 404. A second sector gear 407 is fixedly connected to the outer wall of the fourth gear 405. A rack 408 meshes with the outer walls of both the first sector gear 406 and the second sector gear 407. A sliding block 409 is fixedly connected to the outer surface of the rack 408. A wire hole 411 is fixedly connected to the outer surface of the rack 408. A sliding groove 410 is slidably connected to the outer wall of the sliding block 409.

[0032] The effect achieved by the entire embodiment 2 is as follows: when the second gear 401 rotates, a series of gear transmissions are activated. The second connecting rod 402 drives the worm gear 403 to rotate, the worm gear 403 drives the fifth gear 412, which in turn drives the fourth gear 405 to rotate. The fourth gear 405 drives the third gear 404 and the fixedly connected second sector gear 407 to rotate respectively. The third gear 404 drives the first sector gear 406 to rotate. The first sector gear 406 and the second sector gear 407 rotate synchronously, pushing the rack 408 to move smoothly. Since the rack 408 is fixed with a sliding block 409 and a wire hole 411, the wire hole 411 will move precisely according to the predetermined transmission path, so that the optical fiber cable passing through the wire hole 411 always maintains a stable and uniform state during the translation process, which can better adapt to the wiring requirements of different positions of the circuit and ensure the uniformity of optical fiber coverage of the entire circuit.

[0033] Example 3: Please refer to... Figures 1-6 As shown, the outer walls of the first gear 305 and the second gear 401 mesh with each other. One end of the first connecting rod 306 is rotatably connected to the inner wall of the equipment housing 1. Both ends of the second connecting rod 402 are rotatably connected to the opposite side of the equipment housing 1. The outer surface of the slide groove 410 is fixedly connected to the inner wall of the equipment housing 1. The outer surface of the fifth gear 412 is fixedly connected to a support frame. The outer surface of the support frame is fixedly connected to the outer surface of the main equipment 13 and the inner wall of the equipment housing 1, respectively. The outer wall of the rotating handle 301 is movably inserted into the outer surface of the equipment housing 1.

[0034] The overall effect of embodiment 3 is that the first gear 305 and the second gear 401 mesh with each other, establishing a power connection between the winding mechanism 3 and the translation mechanism 4. When the winding mechanism 3 winds up or unwinds the cable, the rotation of the first gear 305 drives the second gear 401 through meshing, enabling the translation mechanism 4 to adjust the cable position in real time and synchronously according to the winding situation. The first connecting rod 306 and the second connecting rod 402 are rotatably connected to the equipment housing 1, ensuring that the rotation of each component is smooth. The slide groove 410 provides a stable track for the sliding block 409, allowing the wire hole 411 to remain accurate during translation. The mounting frame on the outer surface of the fifth gear 412 firmly supports the main unit 13 of the equipment and related components, improving the overall stability of the equipment. This ensures that the winding mechanism 3 and the translation mechanism 4 can work continuously and stably during long-term, high-intensity fiber optic cabling operations, achieving efficient and uniform winding and management of fiber optic cables, and helping the fiber optic temperature measurement equipment to accurately cover the entire circuit.

[0035] Working Principle: The working principle of the equipment is based on the coordinated operation of the mechanisms in each embodiment. In the winding mechanism 3 of embodiment 1, rotating the handle 301 will drive the transmission disc 302, which is fixedly connected to it, to rotate. Since the winding rod 303 is fixedly connected to the outer surface of the transmission disc 302, the winding rod 303 will rotate synchronously with the transmission disc 302. When it is necessary to connect optical fibers or other cables, the connection can be easily completed using the quick-release connector 304. At this time, the first gear 305 and the first connecting rod 306 work together to maintain the stability and smoothness of the winding operation. The cable is orderly wound and stored during the rotation of the winding rod 303. When the cable is needed, rotating the handle 301 in the opposite direction will quickly unfold the cable. In the translation mechanism of embodiment 2... In step 4, when the second gear 401 rotates, the second connecting rod 402, which is fixedly inserted inside the second gear 401, rotates synchronously, thereby driving the worm gear 403 fixed to the outer wall of the second connecting rod 402 to rotate. The worm gear 403 meshes with the fifth gear 412, and the rotation of the worm gear 403 drives the fifth gear 412 to rotate. Because the outer surface of the fifth gear 412 is fixedly connected to the fourth gear 405 through a shaft, the fourth gear 405 also rotates. The fourth gear 405 meshes with the third gear 404, and the rotation of the fourth gear 405 drives the third gear 404 to rotate. The outer wall of the third gear 404 is fixedly connected to the first sector gear 406, so the first sector gear 406 also rotates. At the same time, the outer wall of the fourth gear 405 is fixedly connected to the first sector gear 406. The fixedly connected second sector gear 407 will also rotate with the fourth gear 405. The first sector gear 406 and the second sector gear 407 mesh with the rack 408. When they rotate, they will push the rack 408 to move. Since the sliding block 409 and the wire hole 411 are fixedly connected to the outer surface of the rack 408, the sliding block 409 slides in the groove 410, and the wire hole 411 also moves accordingly, realizing precise translation adjustment of the cable position. Embodiment 3 further demonstrates the connection between the various mechanisms. The first gear 305 and the second gear 401 mesh with each other, which enables the winding mechanism 3 and the translation mechanism 4 to realize power transmission and linkage control. When the winding mechanism 3 performs the winding or unwinding of the cable, the rotation of the first gear 305 will drive the cable to move. The meshing relationship drives the second gear 401 to rotate, thereby enabling the translation mechanism 4 to synchronously adjust the cable position according to the winding situation. The first connecting rod 306 and the second connecting rod 402 are rotatably connected to the equipment housing 1, ensuring the stability of the rotation of each component of the winding mechanism 3 and the translation mechanism 4. The slide groove 410 is fixedly connected to the inner wall of the equipment housing 1, providing a reliable track for the sliding block 409. The mounting frame on the outer surface of the fifth gear 412 stably supports and fixes the main equipment 13 and related components, enhancing the stability of the internal structure of the equipment. The outer wall of the winding mechanism 3 is movably inserted into the outer surface of the equipment housing 1, making it easy for operators to operate the winding from outside the equipment. Ultimately, the equipment can efficiently and stably complete the winding and translation of the cable.

The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the optical fiber will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
